ABSTRACT

Climate change and broader Anthropogenic environmental risks pose existential threats to humanity. Human-driven environmental change has come to be understood through the concept of the ‘Anthropocene’. Anthropocene risks demonstrate that existing fossil-fuel intensive and growth-oriented capitalist development are unsustainable. The urgent need to transition towards greener forms of development is widely recognised. Comparative Political Economy (CPE) should be well placed to guide and evaluate green transition, yet it typifies a wider disconnect between political economy and environment. This article seeks to understand and transcend that disconnect. Developing a critical genealogy of CPE’s post-war emergence, the article examines CPE’s paradigmatic evolution and fitness for grappling with the Anthropocene. It argues that dominant theoretical paradigms (Varieties of Capitalism and Growth Models approaches) are grounded in a ‘nature/society’ dualism that treats national economic models as environmentally disembedded and causally independent from the Earth System. Economic growth is uncritically elevated as a dominant comparative metric, normative aspiration, and policy objective for capitalist development. These characteristics limit the capacity to engage with green transition. Embedding CPE within ecological considerations, the article selectively repurposes the field’s existing conceptual insights to develop hypotheses concerning comparative capitalisms and green transition in the Anthropocene.

Climate change poses existential threats to humanity. Our current trajectory risks a ‘Hothouse Earth’ scenario in which feedback loops within the Earth System trigger runaway warming and ecosystemic breakdown, heralding a planetary pathway inhospitable to human life. This scenario is possible even if the Paris Agreement target for keeping global warming to within 2 degrees Celsius is met (Steffen et al. 2018). Without large-scale efforts to rapidly decarbonise economies and promote environmentally sustainable practices, we face the possibility of civilisational collapse (Wallace-Wells 2019, Paterson 2020).

An expanding body of interdisciplinary scholarship comprehends this unique situation through the concept of the Anthropocene – a geological epoch in which human societies are primary drivers of climatic transformation (Steffen et al. 2011). More than a pseudonym for global warming, the Anthropocene represents a broader range of changing Earth System dynamics bearing the mark of human agency. Environmental consequences range from collapsing biodiversity prompted by industrial agriculture and rapid urbanisation, to the exhaustion of global fisheries and the reorientation of the Earth’s water, nitrogen, and phosphate cycles (Bonneuil & Fressoz 2016, p. 4).

Existing patterns of growth-oriented and fossil-fuel intensive human economic activity are unsustainable (Gough 2017, Raworth 2017). The need for a green transition towards a decarbonised and environmentally sustainable economy now has broad support. But the objects, actors, and goals of this transition remain ambiguous (Newell, Paterson & Craig 2020, p. 1). Comparative Political Economy (CPE) with its attentiveness to comparative institutional responses to common challenges and holistic theorisation of capitalism, should be well placed to guide and evaluate green transition. Yet CPE typifies the wider disconnect between political economy and ecological concerns, with climate change a troubling ‘blindspot’ (Paterson 2020). Even while environmental constraints on economic development become dangerously apparent, CPE remains silent on the ecological modalities of comparative capitalisms.

In this article, I critically interrogate CPE’s disciplinary foundations to assess its fitness for studying capitalism in the Anthropocene. Recognising the value of a comparative approach to green transition, I ask – how should we study comparative capitalisms in the Anthropocene? I argue that CPE’s theoretical foundations and research agenda limit its capacity to engage environmental issues. Ontologically and epistemologically, CPE is grounded in a ‘nature/society’ dualism that treats national economic models as environmentally disembedded and causally independent from the Earth System. Tracing the field’s post-war development, I show how this dualism is embodied by CPE’s elevation of economic growth as a dominant comparative metric, normative aspiration, and policy goal for capitalist development. The contemporary rise of the ‘Growth Models’ approach entrenches these disabling commitments at a time of heightened environmental crisis. These qualities render the field ill-equipped to grapple with the Anthropocene. Studying capitalism comparatively is, though, vitally important to guiding green transition. We need awareness of how institutional, sectoral, and holistic transformations within and between political economies can function in mutually beneficial and reinforcing ways. I propose that, despite the field’s unecological assumptions and uncritical entanglements with growth, existing analytical insights from comparative capitalism literature contain promising foundations and partial truths that can be environmentally embedded and productively reoriented to engage with green transition.1 This requires leveraging transdisciplinary insights, from ecological economics to Earth System governance, to retool CPE for the Anthropocene. It necessitates an approach to the comparative evaluation of political economies that prioritises issues of energy, emissions, and environmental impact.

I begin by tracing the ontological and epistemological significance of the Anthropocene for the social sciences. In the second section, I explore entanglements between CPE’s post-war emergence and the parallel rise of the economic growth paradigm, demonstrating how anthropogenic environmental threats challenge growth’s continued viability and desirability and question its status within dominant theoretical approaches. The third section evaluates the field’s paradigmatic shift from Varieties of Capitalism to the Growth Models approach, highlighting the field’s thematic narrowing and environmental silences, while revealing the continuity of growth-affirming and unecological assumptions. In the fourth section, I outline alternative hypotheses to guide CPE research into green transition. I conclude by calling for CPE to decentre growth analytically and normatively.

Anthropocene ontology and the nature/society dualism

The Anthropocene is premised on a transformative ontological claim – human societies and activities should be understood as highly interactive drivers of a ‘complex, adaptive Earth System’ (Steffen et al. 2018, p. 8526).2 This claim, supported by abundant empirical evidence linking socio-economic processes with environmental degradation, centres human agency within causal processes shaping the Earth System (Dryzek 2016, p. 940). How exactly human agency is imbricated within these processes is, nonetheless, sharply contested. Critics of the prevailing Anthropocene discourse have argued that it naturalises humanity’s destructive ecological imprint through a species-level analysis that elides sharply differentiated degrees of responsibility attached to sociologically and geographically distinctive social forces (Malm & Hornborg 2014, p. 63, Moore 20172018). Despite disagreements over exactly who bears responsibility for generating anthropogenic environmental risks, there is broad acceptance that destructive interdependencies between human societies and the Earth System disrupt modernist ontological and analytical binaries between ‘nature’ and ‘society’ (Malm & Hornborg 2014, p. 62–3, Bonneuil & Fressoz 2016, Moore 2017, Kelly 2019, p. 1).

Accepting the ontological premise of the Anthropocene means recognising that human institutions depend upon the regulative stability of ecosystemic and biogeophysical foundations. This has significant implications for the social sciences. Many social science disciplines emerged during a period of rapid European economic development in which humans appeared unconstrained by ecological limits (Moore 2017, p. 596). Sociology, for example, was profoundly shaped by the historical coincidence between its disciplinary emergence and accelerated economic development (Catton & Dunlap 1980, p. 24). This led to the construction of social theories premised, often unconsciously, on an idea of ‘human exemptionalism’ that represented human societies as, ‘exempt from ecological constraints’. Modern economic thought has been similarly anchored in a cornucopian postulate of infinitely exploitable natural resources and limitless ecological horizons, framed geographically through their representation as new frontiers to be harnessed for economic expansion (Jonsson 2014).3

Unecological suppositions within modern social sciences leave extant paradigms ill-equipped to respond to the Anthropocene. We need critical genealogies that interrogate paradigmatic foundations of contemporary approaches, opening new paths of enquiry. Scholars have called for the development of new ‘environmental humanities’ and a shift from social to ‘socio-ecological systems’, recognising social relations’ deep entanglement and co-constitutive relationship with biophysical processes (Bonneuil & Fressoz 2016, Moore 2017, p. 598, Dryzek 2016, p. 941). A disconnect remains between Anthropocene scholarship highlighting the nature/society separation underpinning modern social sciences, and the orientation of prevailing paradigms.

Within economics and political economy, dominant paradigms continue to treat economy and environment as causally dissociated. This is true of CPE. Threats posed by climate instability and ecological deterioration are increasingly apparent, and their political salience has risen dramatically, yet the field’s recent evolution has not kept pace. CPE has moved from a focus on ‘Varieties of Capitalism’ (VOC) to a concern with ‘Growth Models’. The Growth Models approach transcends the supply-side preoccupations of VOC, rebooting Keynesian-Kaleckian macroeconomics to identify institutional drivers of aggregate demand across distinctive national economies (Baccaro & Pontusson 2016). But it continues to treat ‘demand’, ‘growth’ and the ‘economy’ as neutral analytical categories, conceptually uncontroversial and independent from environmental contexts. Both VOC and GM approaches overlook the relevance of energy sources and sectors to comparative capitalism. This despite the existence of longstanding traditions of ecological economics that reckon with the perils of fossil-intensive growth within a finite global ecosystem (Georgescu-Roegen 1971, Daly 1974, Costanza et al. 2015). What explains this disconnect between Anthropocene environmental threats, the widely recognised need for green economic transition, and CPE’s narrowing around an unecological problematique of national pathways to economic growth? The following section explores the parallel rise of the economic growth paradigm and the post-war emergence of CPE. I argue that CPE’s rise was conditioned by the emergence of economic growth as a hegemonic developmental framing, becoming increasingly focussed on understanding national pathways to maximising economic growth. This leaves the field unable to critically interrogate the idea of growth itself, along with its deeper analytical foundations.

CPE and the problem of growth

Contemporary ‘ecopolitical’ discourses of green transition diverge over the viability of reconciling growth with environmental sustainability (Buch-Hansen & Carstensen 2021, p. 2). Dominant green growth discourses, supported by institutions such as the World Bank, stress capitalism’s compatibility with sustainability, suggesting that stronger environmental protections can enhance growth (Jacobs 2012, Meckling & Allan 2020, p. 436). De-growth and post-growth perspectives, conversely, argue that continued economic growth and environmental stability are most likely irreconcilable and the growth paradigm itself is an obstacle to an ecologically restorative political economy (Kallis, et al. 2018, Hickel 2020). Despite their breadth and disagreements, prevailing green transition discourses entail consideration of the environmental and energy dimensions of economic growth beyond that provided by dominant CPE approaches.4 These approaches treat growth as an objective, environmentally independent, and largely uncontested comparative metric. Questions of energy, emissions, and resource intensity hardly register. A brief genealogy of the field’s post-war development helps explain the schism between emerging discourses of green transition, historical traditions of ecological economics, and CPE.

The post-war emergence of CPE as a distinctive subfield coincided with the consolidation of economic growth as a hegemonic development goal. The growth paradigm can be understood as an institutionalised way of thinking that represents economic growth as ‘necessary, good, and imperative’ (Kallis et al. 2018, p. 294). Its history is deeply entangled with the rise of the ‘economy’ as an object of analysis. Early foundations date to the birth of political economy from the eighteenth century in France and Britain. As part of the broader fracturing of the natural and social sciences, liberal political economists conceived the economy as a distinctive and self-regulating sphere with independent governing principles (Kallis et al. 2018, 294, Tellmann 2018, p. 3).

It was during the 1930s and 1940s, though, that the modern notion of the economy as a geographically bounded, self-reproductive system crystallised. The formation of a new statistical construct to measure total national economic output, Gross Domestic Production (GDP), played a central role. Pioneering work on the measurement of national income, led by Simon Kuznets’s efforts in the US and the work of Colin Clark, Richard Stone and Keynes’s within the UK during the 1930s and 1940s, shaped the emergence of GDP as a new statistical imaginary that constructed the modern economy as a measurable and governable entity (Desrosières 1998, p. 172, Coyle 2015, p. 12–7, Schmelzer 2016, p. 81–92). These measurements did not account for the depletion of energy resources nor other environmental damage caused by economic expansion (Mitchell 2011, p. 124, 140, Schmelzer 2016, p. 100). By the 1950s economic growth, indicated by increasingly sophisticated techniques of national income accounting, had emerged as a policy goal. A transnational network of Western economic practitioners worked through international organisations to internationalise national income accounts and standardise the primacy of growth (Schmelzer 2016, p. 94).

Growth’s prevalence as a political-economic aspiration underlay the emergence of CPE after WWII. Disciplinary histories trace the post-war revitalisation of CPE to a common source – Andrew Shonfield’s 1965 magnus opus, Modern Capitalism. Shonfield’s comparative study of economic development in the UK, France, Germany and the US, became a touchstone for subsequent generations of scholarship (Hall & Soskice 2001, Clift 2014, p. 7, Baccaro & Pontusson 2016, p. 176, Menz 2017, p. 38). The book persuasively applied the comparative method. Shonfield anchored his investigation into a range of contemporary themes, from planning to full employment, within appreciation of the specific institutional foundations identifiable across capitalist states (Clift 2014, p. 7).

Intellectual histories of CPE usefully establish common points of origin. But these accounts tend to naturalise an important feature of Shonfield’s study – its preoccupation with the drivers, metrics, and possible futures of economic growth. Modern Capitalism is a book shaped by the dominance of growth. Shonfield set out to understand how the stagnation of the Depression-era had been overcome via the sustained economic growth of the post-war period. It was this context of the ‘high prosperity and rapid growth of post-war capitalism’ within the West that motivated Shonfield’s investigation (Shonfield 1965, p. 4–19). He argued that three key factors helped explain the period of unprecedented prosperity during the 1950s and 60s. Firstly, that economic growth ‘has been much steadier than in the past’. Secondly, production had expanded rapidly over the period. Finally, the benefits of the ‘new prosperity’ generated by the growth of economic output had been ‘very widely diffused’ (Shonfield 1965, p. 61–2). This explanatory framework bore all the hallmarks of the growth paradigm’s newfound hegemony. Shonfield sought to explain the overall prosperity of the West, understood as the fruits of economic growth, by arguing that growth had been more stable, rapid, and evenly distributed.

National economic statistics helped bring comparative representation of discreet economic units into being, heightening the empirical and conceptual possibilities of CPE. The interlocking origins of CPE and the growth paradigm had important normative implications too. Shonfield’s study carries the imprint of a liberal cornucopian optimism that conjures visions of unending progress and unlimited resource frontiers. He optimistically opines that ‘continuing prosperity and uninterrupted growth on the scale of recent years are possible in the future’, and suggests that, ‘the underlying conditions in the second half of the twentieth century are more favourable than at any time in the history of capitalism’ (Shonfield 1965, p. 63–4).

Shonfield’s work was critical to the emergence of CPE, reviving the comparative method and identifying core themes of post-war capitalism. Viewed from the vantage point of the Anthropocene, though, this growthist optimism rests on an ontological nature/society dualism that dangerously disguises ecological harms incumbent to capitalist development. The rise of the ‘Modern Capitalism’ that Shonfield celebrated was linked, causally and chronologically, to unprecedented intensification of environmental deterioration. Economic growth was central to this process (McNeill & Engelke 2016, p. 132–54, Dryzek & Pickering 2018, p. 13). Three quarters of human-induced carbon dioxide emissions into the atmosphere occurred post-1945. The number of motor vehicles increased from 40 million to 850 million. The volume of annual plastic production increased from 1 million tons in 1945 to almost 300 million by 2015. Production of nitrogen synthesisers, predominantly for use in agricultural fertilisers, increased from 4 million tons to over 85 million tons across the same period (McNeill & Engelke 2016, p. 4). Earth Scientists refer to this period as the ‘Great Acceleration’ – a concept that captures the ‘holistic, comprehensive and interlinked nature of the post-1950 changes simultaneously sweeping across the socio-economic and biophysical spheres of the Earth System, encompassing far more than climate change’ (Steffen et al. 2015, p. 82). From the 1950s, there is clear evidence of major shifts in the condition of the Earth System exceeding the normal range of variability of the Holocene, and driven by human socio-economic activity (Steffen et al. 2015, p. 93–4).

The Anthropocene prompts a critical re-evaluation of the drivers of growth and prosperity. It raises grave doubts over the viability of present and future economic growth if we are to respond to and contain multiple, intersecting, environmental threats. While orthodox economic thought elevated growth to an uncontested status, a shadow tradition of ecological thinking, stressing finitude, entropy, and waste, developed alongside (Boulding 1966, Georgescu-Roegen 1971, Daly 1974). Ecological economists have long acknowledged the biophysical dimensions of economic growth (Gowdy & Erickson 2005, p. 218). Economic processes involve the conversion of energy and natural resources into ‘goods, services and waste’ (Kallis et al. 2018, p. 292). This has important implications for addressing the leading edge of Anthropocene environmental instability – rapid global warming driven by greenhouse gas emissions. There are firm grounds for scepticism concerning the prospects of decoupling economic growth from resource use and, critically, carbon emissions. Even when efficiency gains are made, their impact in lowering costs within a market-based system tends to lead to ever higher consumption of finite resources and associated increases of environmentally damaging pollution (Kallis, et al. 2018, p. 292).

Green growth arguments have gained currency in policy discussions (Meckling & Allan 2020, p. 436).5 These arguments rest on optimistic outlooks for the possibility of ‘decoupling’ growth from both carbon emissions and wider resource use (Jackson 2017, p. 87). There is some evidence to support claims for ‘relative decoupling’, whereby the emissions or material intensity of economic output declines relative to the rate of economic growth, signalling an improvement in efficiency. But meeting the Paris Agreement target of 2 degrees warming, in the context of continued economic growth, requires ‘absolute decoupling’ with regard to carbon emissions – an absolute decline in emissions while economic output continues to rise. There is no historical evidence of absolute decoupling on this scale (Jackson 2017, p. 84–90). Hickel and Kallis’ literature survey (2019, p. 1) finds that absolute decoupling of growth from carbon emissions is, ‘highly unlikely to be achieved at a rate rapid enough to prevent global warming over 1.5C or 2C’ (Hickel and Kallis 2020, p. 1). Evidence suggests that although absolute decoupling of carbon emissions from economic output is possible (and underway in some countries) it is very unlikely to occur fast enough to meet the Paris Agreement targets within a context of continued economic growth. The problem, the authors conclude, is growth itself. Growth leads to increased demand for energy, making the transition to renewable energy harder and leading to increased emissions from changing land use and industrial processes (Hickel and Kallis 2020, p. 12). Whatever our view on the viability or otherwise of green growth, the nexus between energy and emissions concerns needs to be given much greater prominence in assessing comparative capitalisms.

Environmental anxieties surrounding economic growth are not new. From Malthusian predictions about population in the eighteenth century to the ‘Limits to Growth’ report in the 1970s, concerns about pressures on finite natural resources and fragile ecosystems have shadowed confident prognoses of economic progress (Jonsson 2014, p. 14, Dryzek 2016, p. 939). Scientific evidence and understanding surrounding the ecological impacts of economic growth is stronger than ever. Why, then, has CPE moved further away from a critical appraisal of the prospects for capitalism and growth over recent years? To understand this paradox, I argue, we need to understand disciplinary patterns of knowledge production within CPE.

From VOC to Growth Models

CPE has evolved in response to major transformations within the global economy (Clift 2014, p. 7, Baccaro and Pontusson 2016, p. 176). Accelerated economic globalisation in the 1990s inspired the emergence of Hall and Soskice’s (2001) influential ‘Varieties of Capitalism’ (VOC) framework, exploring possibilities for continued national economic diversity in a context of heightened international competition. After the 2007/8 financial crisis, a contending framework emerged. The ‘Growth Models’ (GM) perspective pioneered by Baccaro and Pontusson (20162020) addresses VOC’s limitations by highlighting neglected issues of inequality and distributional struggle. It has inspired a large volume of supportive scholarship (Perez & Matsaganis 2018, Amable et al. 2019, Bohle & Regan 2021, Rothstein 2021, Schedelik et al. 2021, Stockhammer 2021).

What are the core claims of these two approaches? I begin with VOC. Hall and Soskice introduced VOC in the early 2000s, during the high-water mark of globalisation. They rejected the premise that globalisation would drive comparative institutional convergence, seeking to demonstrate how distinctive forms of comparative advantage could be maintained. Hall and Soskice displaced CPE’s traditional focus on the state and positioned firms as the pivotal agents. Rational firms encounter specific ‘coordination problems’, with their capacity to deliver economic goods ultimately dependent on effective coordination with a diverse institutional actors, from employers’ associations to trade unions. Identifying five core spheres within which firms must overcome coordination problems, Hall and Soskice developed an influential twofold typology of ‘liberal market economies’ (LMEs) and ‘coordinated market economies’ (CMEs). Firms within each typology rely upon different mechanisms to secure effective coordination (Hall and Soskice 2001, p. 1–8).

Importantly, both types of economy could prosper under conditions of advanced globalisation, confounding expectations of cross-national convergence. This claim is underpinned by the notion of ‘institutional complementarities’ – whereby the presence of one institution increases the returns from/efficiency of another. Institutional complementarities lead to patterns of institutional clustering in response to the competitive pressures of international trade. Nations with specific forms of coordination in some spheres of the economy, ‘should tend to develop complementary practices in other spheres as well’ (Hall and Soskice 2001, p. 17). Complementarities generate self-reinforcing positive feedback loops incentivising further institutional alignment.

VOC dominated CPE from the early 2000s. Despite various critiques, VOC’s agenda-setting status endured. More recently, though, the paradigmatic centrality of VOC has been loosened. Scholarship has emerged utilising a new ‘Growth Models’ framework for comparative capitalism. The landmark contribution is Baccaro and Pontusson’s (2016) article, ‘Rethinking Comparative Political Economy’. They respond to a perceived fracturing of CPE scholarship during the post-crisis period – a division between those positing a common regressive developmental trajectory and others who claim that diversity endures. They seek to transcend this apparent division through greater sensitivity to both commonalities and differences between advanced capitalist economies (Baccaro & Pontusson 2016, p. 176)

Baccaro and Pontusson deploy a Post-Keynesian/Kaleckian macroeconomic perspective that emphasises the importance of different sources of aggregate demand, particularly exports and household consumption, as determinants of capitalist variation. Distinguishing between export-led and consumption-led models of growth, they associate each model with distinctive implications for inequality and distributive conflict. These growth models are both ‘more numerous’ and ‘more unstable’ than the VOC typologies. Emphasising the conditioning impetus of the post-Fordist period, they distinguish their view from the more deeply rooted institutional equilibria posited by VOC, hinting at greater (regulation school-inspired) sensitivity to transformations in capitalist production regimes (Baccaro & Pontusson 2016, p. 175-6, 186).

Exploring four cases, Germany, Sweden, Italy and the UK, they construct their model on observations of a cross-cutting post-Fordist decline of wage-led growth and an associated distributional shift in favour of capital and ‘high-income households’ (Baccaro & Pontusson 2016, p. 198). This presents a common puzzle for these economies – how can the ‘faltering wage driver’ of aggregate demand be replaced? How can economic growth be maintained in a context of secular wage decline? The divergent pathways of response to this common problem are the comparative crux for establishing patterns of continuity and variation across the cases. Germany, Sweden and the UK represent three different ‘solutions’ to the problem of how to generate post-Fordist growth, while Italy’s experiences of ‘sluggish growth’ and ‘overall stagnation’ cast it as a deviant failing case (Baccaro & Pontusson 2016, p. 176).

GM scholarship offers valuable correctives to VOC’s deficiencies. VOC’s technocratic and depoliticised representation of capitalism has been charged with ignoring crises and class struggles (Streeck 2010, Bruff 2011). GM literature counters VOC’s understatement of class and inequality through greater attentiveness to distributional dynamics. It also challenges the hallmark VOC distinction between LMEs and CMEs, which has been criticised for overlooking the unevenness of institutional development, neglecting the contingent and politically constructed nature of pressures for ‘convergence’ emerging from globalisation, and reifying ideal types into actually existing forms of capitalism (Brenner, Peck & Theodore 2010, p. 186–8, Hay 2004, p. 242–3, Hay 2020, p. 307). By contrast, GM scholarship highlights substantial degrees of variation within archetypal LMEs and CMEs across comparative variables such as inequality growth and household indebtedness (Baccaro & Pontusson 2016, p. 178–84).

The timing and content of this nascent theoretical shift from VOC to GM reflects both CPE’s sensitivity to changing structural conditions within global capitalism and the selectiveness of that sensitivity. The success of the GM perspective is attributable to VOC’s failure to depict actually existing capitalism. Post-2007/8, VOC’s depoliticised, supply-side vision of institutional dynamics no longer resonates with advanced capitalist economies characterised by rising inequality, divisive legitimation crises, and large-scale macroeconomic intervention. The GM approach substantively incorporates these themes. Simultaneously, though, it evades a critical question facing contemporary capitalism – how can advanced economies implement rapid and large-scale green political-economic transition in response to anthropogenic environmental instability? Despite the urgent need for decarbonisation, the GM approach continues VOC’s exclusion of energy, emissions, and environmental profiles from its typological representations. While opening to broader macroeconomic traditions, GM literature reproduces VOC’s neglect of ecological economics and green economic thought.

What explains this selective engagement with contemporary themes in global capitalism? Why are some traditions of economic thought leveraged while others are ignored? What determines issue hierarchies in the construction of theory? Social science paradigms shape future research patterns by identifying theoretically significant facts, creating a hierarchy of research questions, and determining appropriate forms of evidence (Geddes 2003, p. 7). Academic disciplines are highly networked communities guided by specific rules about ‘admissible’ work, norms about how research should be conducted and results presented, and frequently, ‘a clear sense of where disciplinary boundaries reside’ (Rosamond 2007, p. 235). These insights render CPE’s neglect of anthropogenic environmental threats intelligible. Despite notable differences between VOC and the GM perspective, foundational theoretical continuities hamper the field’s potential to engage green transition. Core background assumptions underpin CPE’s paradigmatic development. These assumptions delimit specific parameters about what constitutes a legitimate object of enquiry, permissible dimensions of comparative analysis, appropriate methods, and plausible assumptions regarding capitalism.

Two foundational continuities, defined in Figure 1 below as first order theoretical assumptions, situate both VOC and the Growth Models perspective within the growth-affirming lineage of CPE post-Shonfield. Firstly, at the ontological level, both perspectives maintain a nature/society dualism that represents capitalism as a bounded an internally self-reproductive system independent of environmental entanglements. Capitalism is understood to be exogenous to environmental considerations, with the analysis of how capitalist institutions change over time isolated from consideration of Earth System dynamics. These unecological assumptions are not confined to CPE. They form an often unconscious background to the majority of the social sciences (Catton & Dunlap 1980, p. 23). Holocene conditions of relative Earth System stability ensured that political and economic institutions could assume the continued stable presence of the ecological systems that support human society (Dryzek 2016, p. 938). Secondly, in a normative/analytical sense, GDP growth functions positively as a guiding aspiration and primary axis of comparative differentiation for evaluating capitalism.

Figure 1. Comparative capitalisms and the Anthropocence.

These assumptions shape the primary research questions and understanding of capitalist development. VOC asks which economic policies can enhance economic performance, focusing on increased institutional efficiency geared towards ‘higher rates of growth’ as an explicit objective (Hall & Soskice 2001, p. 2). GM literature relies on a normative/analytical binary between ‘successful’ and ‘failing’ growth strategies. Institutional characteristics of national economies are considered with regard to their propensity to threaten or unbalance economic growth (Baccaro & Benassi 2017, p. 85–6). Italy is considered as a deviant case due to its inability to secure high levels of growth (Baccaro & Pontusson 2016, p. 176). GDP is elevated as the dominant comparative metric and normative standard for evaluating economic development. Ecologically embedded indicators of capitalist development – central to ecological economics – are excluded. This prohibits recognition of potentially positive environmental and social impacts of displacing growth’s centrality.

Regarding second order foundations, the VOC approach identifies rational firms as primary agents. The economy is viewed as a sphere within which, ‘multiple actors develop competencies by devising better ways of coordinating their endeavours’ (Hall & Soskice 2001, p. 45). This neglects the environmental foundations of economic activity. From the firm to the macro-economic scale, specific assumptions about ‘efficiency’ and ‘complementarity’ are constructed outside of environmental considerations of energy intensity, waste, or emissions (Hall & Soskice 2001, p. 17, 32, Soskice 2007, p. 89, Iversen, Soskice & Hope 2016, p. 171). A Ricardian premise of efficient national economic responses to international trade competition, via comparative institutional advantage, naturalises unecological assumptions about economic efficiency by ignoring the environmental preconditions and consequences of trade and specialisation. In rare instances where the VOC framework has been mobilised to engage issues of climate change adaptation comparatively, its unecological foundations are left unquestioned (Mikler 2011, Mikler & Harrison 2012).

GM literature assumes a more macroeconomic vantage point and centres distributional struggles between social forces. The governing macroeconomic assumptions of CPE are shifted from a New Keynesian (VOC) to a Post-Keynesian (GM) axis. This move enhances recognition of aggregate demand’s impact on long-term productive potential, increases awareness of class power as a distributional determinant, and enables more optimistic views on the scope for, ‘growth-enhancing policy interventions’ (Baccaro & Pontusson 2020, p. 17–22). But it too treats core analytical categories such as consumption, demand, income and production as environmentally disembedded. It posits a set of logical macroeconomic interrelations independent of environmental context or consequences and fails to consider ecological constraints on aggregate demand management (Baccaro & Pontusson 2016, p. 182).

Ultimately, the principal disagreement between the two perspectives is fairly minor. It centres on the prospects for macroeconomic intervention to positively enhance long-term wage growth and employment. VOC’s New Keynesian origins lead to a more pessimistic reading, while the GM perspective leverages Post-Keynesian/Kaleckian insights to generate more auspicious conclusions. In reaching these contrasting conclusions, both theories explicitly draw inspiration from strands of twentieth century macroeconomic theory. Mainstream economic theory, from neoclassical to Keynesian, has systematically excluded ecological costs of economic activity, conceptualising the economy as an extra-natural system divorced from ecological foundations (Mitchell 2011, p. 136–41). The rise of Keynesian economic thought, a common lineage for both approaches, is causally imbricated with the Great Acceleration. Keynesian assumptions about the capacity to boost demand and attain full employment through increasing economic output discount the ecological foundations of capitalism (Mann & Wainwright 2018, p. 243–4). Energy and emissions considerations do not feature as constraints on the prospects for growth. This common theoretical inheritance severely limits the capacity of contemporary CPE to think ecologically about political economy. Ecological economics and Earth Systems scholarship provide more fertile transdisciplinary resources for CPE to engage with green transition.

Problematising CPE’s environmental silences is not sufficient to develop a comparative research agenda for green transition. Nor should we entirely discount achievements of prevailing approaches, which have been highly productive for understanding comparative capitalisms. Instead, we should consider how existing analytical insights might be repurposed to equip CPE for the Anthropocene. This requires reviewing additional conceptual deficiencies characteristic of the field. Firstly, concerning institutional dynamics, scholars have challenged VOC’s narrow, rational-functionalist, understanding of institutions that reduces the motivations of institutional development to efficiency gains, squeezing out the role of political struggles, accidental/unintended outcomes, and cultural or ideational causes (Watson 2003, p. 232, Hay 2004, p. Streeck 2010, p. 27, Clift 2014, p. 101–13). VOC has further been criticised for relying on a ‘punctuated equilibrium’ model that understates incremental institutional development (Streeck & Thelen 2005). Secondly, VOC’s methodological nationalism produces a truncated sense of the spatio-temporal parameters of capitalist development that reifies national territorial boundaries, obscures the unevenness of economic development, and occludes the relevance of different scalar determinants of institutional transformation (Peck & Theodore 2007, p. 738–40, Brenner, Peck & Theodore 2010, p. 187–8). Shallow historical contextualisation neglects longer-term developmental dynamics, including sources of crisis and instability, as well as the formative impact of deep-rooted historical antecedents such as distinctive trajectories of industrialisation (Jessop 2014, p. 48, Coates 2014, p. 173). Thirdly, critics have questioned VOC’s rationalist firm-centred ontology and a related down-playing of the importance of state capacity. Assuming rational firms exaggerates functional, utility maximising motives, and disregards cultural and contingent determinations of institutional development (Hay 2005, p. 111). By examining the firm-centred micro-foundations of capitalism, VOC offers an underdeveloped sense of macro-political structures (Hancké et al. 2007, p. 14–6). Finally, VOC has downplayed the importance of sectoral differences, determinants, and comparisons within and across states (Hay 2005, p. 110, Crouch, Schröeder & Voelzkow 2009, p. 656–7).

Owing to the field’s paradigmatic convergence around an increasingly demarcated research agenda, some of these limitations shape the GM perspective too. Conceptually, GM’s spatio-temporal coordinates are comparably narrow. The approach shares VOC’s methodological nationalism, treating coherent macro-economic models within territorial states as privileged units of analysis. GM’s scalar deficiencies render it similarly inattentive to subnational unevenness (Clift & McDaniel 2021, p. 2). In terms of historicising capitalism, Baccaro and Pontusson (2016, p. 176, 2020, p. 24) posit the post-Fordist transition of the 1970s, and the resultant decline of wage-led growth, as a common stimulus prompting divergent comparative responses. But the heavy reliance on macro-economic theory, with its ahistorical ontological foundations, ensures little attention is paid to the historicity of institutions.

Yet GM scholarship also transcends conceptual weaknesses of VOC to provide firmer foundations for engaging green transition. Regarding institutional dynamics, Baccaro and Pontusson draw on the ‘power resource tradition’ to foreground how competing social blocs and electoral coalitions shape institutional outcomes. A Gramscian conception of political hegemony gives greater scope for ideational determinants of institutional change too (Baccaro & Pontusson 2019, p. 1–3). Enhanced attentiveness to sectoral components of growth models provides clues for how we might examine green transition comparatively. Departing from VOC’s firm-centric foundations, Baccaro and Pontusson construct a broader ontology grounded in distributional struggles between distinctive socio-economic coalitions and sectoral interests.6 This enables a stronger foundation for considering the variety of actors that might shape green transition.

Despite their environmental elisions, then, CPE perspectives contain partial foundations for a comparative approach towards green transition. Existing scholarship often focuses narrowly on carbon markets (Newell & Paterson 2010, Bryant 2019), or the agency of particular actors (Wright & Nyberg 2015), without assessing comparative institutional variation and continuity. Literature on socio-technical transitions shares CPE’s institutionalist ontology and emphasis on path dependency, but lacks a wider macro understanding of comparative political-economic dynamics (Unruh 2000, Lockwood et al. 2017).

A CPE approach enables comparative assessment of national economic profiles, institutions, and sectors to inform specific pathways for green transition. Policy interventions required for green transition vary with the institutional characteristics, sectoral composition, and supply/demand drivers within political economies. For example, export-led (Germany) and consumption-driven (UK) economic models will likely have distinctive modalities of environmental impact. Understanding trade and payments interdependencies between countries, linked to comparative specialisation, enhances possibilities for mutually reinforcing and coordinated green transitions. Identifying comparative drivers of environmental harms can differentiate between multi-scalar clusters of institutions that produce negative environmental effects, and those that generate ecologically restorative prosperity. Comparative modelling could facilitate policies that identify and promote ecological complementarities – whereby the existence of one green institution/sector increases the ecological benefits available from another – between institutions and sectors. For example, enhancing sustainable, local non-meat agricultural production and promoting vegetarian offerings within the hospitality sector.

As I show in the research hypotheses below, theoretical insights from existing perspectives can be leveraged directly, or productively inverted, to equip CPE to engage with green transition. These hypotheses attempt to illuminate a path beyond the nature/society dualism within CPE and, correspondingly, to decentre the analytical primacy of growth while maintaining valuable insights from CPE scholarship to examine ecologically embedded variables.

Studying comparative capitalism in the Anthropocene

Capitalism in the Anthropocene no longer operates within Holocene conditions of benign climatic stability. Socio-economic institutions must be conceptualised in relation to a broad set of ‘Anthropocene risks’ related to different forms of environmental instability. They emerge from human-driven (anthropogenic) processes, demonstrate interactive patterns of global socio-ecological connectivity, and display ‘complex, cross-scale relationships’ (Keys, et al. 2019, p. 668). Acknowledging these risks has important implications for CPE, which situates institutional analysis at the core of its intellectual agenda (Clift 2014, p. 16). It makes sense, therefore, to begin our hypotheses with a consideration of institutional dynamics.

Hypothesis 1: Pathologically path dependent institutions drive environmental instability and face greater pressures for transformation

CPE emphasises path dependent institutional development (Clift 2014, p. 101–6).7 Within VOC, feedback mechanisms arising from ‘institutional complementarities’ shape path dependent development towards typological termini (Hall & Soskice 2001, p. 1, 17, Soskice 2007, p. 89, Iversen, Soskice & Hope 2016, p. 164). GM scholarship shares a conviction in path dependency (exemplified by two prevailing post-Fordist growth models), but views institutional development as more politically contingent. Path dependency is central to the political economy of green transition but must be properly integrated with environmental dynamics.

Path dependent processes of self-reproduction allow powerful institutions, from fossil-fuel companies to state agencies, to reassert dominance and propagate environmentally damaging behaviours. Dominant institutions maintain growth’s hegemony despite destructive environmental consequences. Dryzek and Pickering (2018, p. 23) describe these processes as ‘pathological path dependency’ – disconnecting human institutions from Earth System dynamics by privileging economic imperatives over ecological awareness. Such processes do not reflect a benign logic of environmentally neutral and efficient capitalist development as envisaged by VOC. They are ecologically embedded and dangerously disrupt Earth System dynamics (Dryzek 2016, p. 937, Dryzek & Pickering 2018, p. 23). Recognising pathological path dependency disrupts the nature/society dualism by highlighting the ecological foundations of institutions. Pathological path dependency is a critical comparative variable with material and ideational determinants. The institutional embeddedness of the growth paradigm itself is a pathologically path dependent force and an object for comparative evaluation.8

As scholarship on ‘carbon lock-in’ demonstrates (Unruh 2000, Seto et al. 2016) dominant capitalist institutions, social practices, and technologies are embedded in and (re)productive of environmentally damaging logics. CPE can connect these insights to a holistic, critical, assessment of comparative capitalism. Pathologically path dependent institutions, firms, sectors and economic discourses, those that are most carbon-dependent and environmentally damaging, will face greater transformative pressures and more contested institutional trajectories. National capitalisms with stronger environmental political coalitions and lesser dependency on pathologically path dependent energy sources, sectors, and accumulation strategies will likely respond more quickly and effectively to Anthropocene challenges.

Hypothesis 2: The Anthropocene stretches spatio-temporal determinants of capitalist development

The Anthropocene transforms spatio-temporal parameters of capitalist development. Temporally, the Anthropocene stretches diachronic determinants of institutional change (Malm 2016, p. 26). Imperatives for institutional change are determined by responses to historically rooted Earth Systems shifts and an anticipatory approach grounded in longer-term assessments of future environmental trajectories. Once effects of global warming, natural resource depletion, and ecosystemic exhaustion impinge radically on the functioning of capitalist institutions it will be too late for ameliorative action (Jackson 2017, p. 16). Goals for institutional development are increasingly shaped by scientific consensus (exemplified by IPCC reports) grounded in a broader temporal framing than typical calculations of business leaders, investors, and politicians. Concretely, temporal elongation manifests as comparatively distinctive time-frames and strategies for decarbonisation and infrastructural transformation, exemplified by national plans for reaching ‘Net Zero’ carbon emissions.9 These tendencies will likely generate common but differentiated movements towards extensive future-oriented and state-directed developmental goals across national capitalisms.

Temporal reconfigurations are linked to variegated spatial dynamics. Anthropocene risks are shaped by global socio-ecological connections and multi-scalar relationships (Keys et al., p. 2019). Responding to these threats also has multi-scalar dimensions. Scholarship on technological transitions demonstrates the multiple levels of infrastructural and social change involved in decarbonisation (Geels 20022014). Politically, responses to Anthropocene risks are increasingly articulated through multiple, interdependent, governance scales evidenced by the emergence of ‘transnational climate change governance’ (Bulkeley et al. 2014). Globally, UN climate conferences increasingly shape national economic policies around green transition. At regional and national scales, discussions of Green New Deals emphasise supranational and state capacities in pursuit of decarbonisation and wider sustainability goals. These scales are also increasingly interwoven. A genuinely multi-scalar approach to CPE, rather than exclusive prioritisation of the national, is required to engage with the different levels of agency involved in the political economy of green transition.

Hypothesis 3: States (not firms) are the pivotal actors in the political economy of green transition

The emergence of VOC displaced the state’s centrality from CPE. GM scholarship has restored Keynesian convictions in effective state intervention (Baccaro & Pontusson 2016, p. 178). Both approaches understate state capacity as a comparative variable. Green transition relies heavily on the political power, coordinative capacity, and infrastructural reach of states (Johnstone & Newell 2018, p. 72–3).10 Although interactions among multiple actors are involved in green transition, from corporations to social movements and individual consumers, these actors will likely pivot around attempts to contest legal, regulatory, and fiscal conditions underpinned by sovereign state authority. The urgency, scale, and complexity of activity required to effectively decarbonise and reorient economies within the prescribed time-frames requires the authority and coordinating capacity of states. This is exemplified by different proposals for Green New Deals, all of which rely on the fiscal, monetary, and legal-regulatory capacities of states to enact rapid transition away from fossil-fuel intensive economic models. Globally, inter-state bargaining within climate negotiations increasingly establishes (aspirational) parameters for national economic development.

State capacity is a critical determinant of comparative pathways towards green transition. Pre-existing modalities of state intervention are likely to condition national responses to environmental challenges. For example, the tradition of ‘Treasury Control’ within the UK has thwarted green developmental initiatives and propagated the dominant financial accumulation regime (Craig 2020). States are also pivotal sites for the political contestation of environmental issues by distinctive social forces and to the embedding of environmental concerns within public, legal, and regulatory institutions. Historically distinctive models of state authority facilitate differential degrees and forms of engagement with environmental movements (Dryzek et al. 2003). Growth Models’ Gramscian-inspired rediscovery of links between economic models, political coalitions, and legitimation strategies opens paths towards a more politicised understanding of the state that recognises the importance of environmental politics.

Hypothesis 4: Sectoral compositions and characteristics shape modalities of environmental damage and condition trajectories of green transition

Sectoral characteristics of national capitalisms are critical to producing (and ameliorating) Anthropocene risks. In aggregate, national capitalisms have distinctive environmental impacts dependent upon their sectoral make-up and specialisation within the global division of labour. For example, export-oriented economies characterised by strong manufacturing sectors are likely to have different energy and resource requirements, as well as waste and emissions implications, than consumption-led and services dominated economies. Industrial economies tend to have higher raw materials usage and physical imports compared to the lower material footprints of service economies (EU 2016).

At the level of analytically modelling comparative economies, GM’s focus on the sectoral and geographical orientation (export-led vs consumption-led) of demand drivers should be integrated with comparative environmental indicators. Measurements more commonly employed by ecological economics, such as Domestic Materials Consumption and Total Resource Consumption, should be central to CPE. This would facilitate understanding of which sectors must be contracted, or usefully expanded, in pursuit of ecological stability. Sectors may have disproportionately large environmental impacts relative to their contribution to growth, making them more salient for comparative analysis.11 Encouraging ecological complementarities between sectors can promote environmentally beneficial development.

Some sectors matter more than others. The absence of energy considerations from the typologies developed by VOC and GM literature signifies CPE’s environmental neglect. Whether or not different national capitalisms are powered by coal, oil, nuclear or renewables is a crucial variable for understanding patterns of cross-national continuity and difference in the political economy of green transition. For example, Germany has committed to much less ambitious targets for coal phase-out than the UK, due to the greater power of coal unions and companies (along with supportive energy-intensive sectors benefiting from low energy prices), as well as greater employment in the coal sector (Brauers, Oei & Walk 2020). Petrostates and those dominated by the coal industry are particularly significant, producing disproportionate CO2 emissions relative to GDP.12 Recognising that economic size alone does not accord with the importance of a national economy for green transition deprivileges GDP’s ordering of national economies’ analytical importance.

Given the vast investment requirements of green transition and the power of finance, financial sector characteristics are critical. The reluctance of powerful asset managers to endorse environmental shareholder resolutions suggests that considerable political mobilisation is required to harness the commanding heights of finance for green transition (Buller & Braun 2021). Agricultural orientations are significant. Environmental harms and emissions produced by the ‘industrial grain-oilseed-livestock complex’ point to the significance of livestock farming and meat consumption in environmental degradation (Weis 2013, p. 66). In large meat producing countries such as Brazil and the US, curbing these sectors is critical. National strategies and timeframes for green transition will be shaped by the environmental modalities of leading sectors, the relative power of social forces that standing to lose/benefit from curbing environmentally damaging sectors, and the relationship between energy sectors and the wider economy.

Conclusion

The arrival of the Anthropocene profoundly unsettles the modern social sciences. Theories grounded in the nature/society dualism are unsuited to reckoning with proliferating environmental risks and destructive interdependencies between socio-economic institutions and Earth Systems dynamics. Across the social sciences, critical genealogies of incumbent paradigms and new interdisciplinary perspectives are required to equip scholars for our rapidly changing environmental context. CPE has both an important responsibility for engaging in this project and much to offer if it does. Given the causal complicity of fossil-fuel capitalism in the making of the Anthropocene, and the centrality of economic transformation to ameliorating its effects, those of us who take capitalism as our object of study have a special responsibility to engage these issues. In a more concretely institutional sense, scholars of CPE have much to offer as a framework for understanding, evaluating, and guiding comparative pathways of green transition.

In this article, I have begun a critical genealogy of CPE’s modern development with the intention of appraising and encouraging the field’s capacity to engage substantively with the challenge of green transition. Retracing the field’s historical development, I argued that CPE’s post-war emergence alongside the crystallisation of growth’s hegemony instilled scholarship with an assumption of the environmental neutrality of economic development and an uncritical disposition towards growth. Appraising the more recent emergence of VOC and Growth Models approaches, I examined CPE’s paradoxical narrowing around an uncritical orientation to growth maximisation despite mounting environmental threats and heightened awareness of the links between capitalism and climate. In the penultimate section, I developed provisional hypotheses intended to tentatively recalibrate CPE scholarship towards fuller engagement with environmental issues. These hypotheses need to be evaluated through comparative empirical assessments of diverse national plans and pathways towards green transition.

I have made the case that ‘climate issues’ are not simply another empirical domain to be incorporated into existing CPE approaches, but rather require reconsideration of our approach to studying comparative capitalisms. I finish by calling for CPE to rediscover the conjunctural sensitivity and responsiveness that is a hallmark of the field, rather than succumbing to forms of intellectual path dependency that limit its analytical horizons and practical applications. Recognising capitalism’s environmental embeddedness requires rethinking theoretical foundations and decentring CPE’s preoccupations with economic growth. What we might establish as a comparative analytical metric and normative goal in place of growth, or whether indeed we should seek a direct substitute for GDP’s role, remains an open question requiring further consideration by scholars of CPE.

Abstract

In the Anthropocene, humankind has become a quasi-geological force. Both the rapid development as well as the depth of intervention of new technologies result in far-reaching and irreversible anthropogenic changes in the Earth’s natural system. However, early and development-accompanying evaluation of technologies are not yet common sense. Against this background, this review article aims to compile the current state of knowledge with regard to the early sustainability assessment of technologies and to classify this status quo with respect to the key challenges of the Anthropocene. To that end, the paper initially outlines major existing definitions and framings of the term of sustainability. Key milestones, concepts and instruments with regard to the development of sustainability assessment and technology assessment (TA) methodologies are also presented. Based on this overview, the energy sector is used as an example to discuss how mirroring ongoing transformation processes can contribute to the further development of the TA framework in order to ensure an agile, goal-oriented, and future-proof assessment system.

Introduction

For the first time in history, human development is characterized by a coupling of technological, social and geological processes. In this new geological epoch of the Anthropocene (Crutzen and Stoermer, 2000), humankind has become a quasi-geological force that profoundly and irreversibly alters the functioning of the Earth’s natural system (Potsdam Memorandum, 2007).

The main reasons for this extraordinarily high range of human activity are the exponential increase in the world’s population, production and consumption, as well as an increasing acceleration of industrial processes. New technologies are being developed that enable a particular high sectoral depth of intervention as well as a fast marketing of products and applications. As a result, they impose significant pressure on a wide range of sectors to change and adapt to the speed of innovation. Ultimately, society as a whole is urged to react to the impacts generated by the new technologies. A prominent example of a technology with such a high level of intervention is additive manufacturing. Also known as 3D printing, additive manufacturing is seen as a key technology for digitalization due to their production flexibility, the possibilities for function integration and product individualization. Beyond acceleration of innovation times, however, their use also allows for a reduction in component weight and thus a reduction in operating costs, which can promote resource-efficient manufacturing (Bierdel et al., 2019). However, additive manufacturing can create new consumption incentives due to faster product cycles and poses risks to new producers by shifting work and related hazardous substance risks to residential environments (Umweltbundesamt, 2018).

Both the rapid development as well as the depth of intervention of new technologies and materials result in anthropogenic changes in Earth system processes that can otherwise only be caused by meteorite impacts, continental drift and cyclical fluctuations in the Sun-Earth constellation. For example, the effects on the Earth’s nitrogen cycle are particularly serious. Through the ability to synthesize artificial nitrogen compounds by means of the Haber Bosch process, humans have managed to feed 48% of the global population. With increases in fertilizer usage, however, the nitrogen cycle has been pushed far beyond sustainability and nitrate pollution being responsible for increasing dead zones in coastal areas. Furthermore, due to the use of fossil fuels and intensive agriculture, CO2 concentrations in the atmosphere have reached a level last approached about 3 to 5 million years ago, a period when global average surface temperature is estimated to have been about 2°C–3.5°C higher than in the pre-industrial period (NAS and Royal Society, 2020).

The harmful effects of the technologies on the biosphere are fueled by the fact that technological developments are usually faster than political and technical countermeasures. Moreover, in many cases, technical countermeasures still focus on efficiency improvement strategies, less hazardous substitutions of substances as well as end-of-pipe cleaning technologies. While this approach has yielded some success in the past, it also entails the risk of rebound effects.

Against this background, there is an increasing need for comprehensive approaches to analysis and solutions. Hence, the following key questions arise how to deal with the challenges regarding the prospective assessment of technologies in the era of the Anthropocene:

Firstly, which applications of technologies are beneficial with respect to a sustainable development, and which ones we should rather abandon?

Secondly, which methodological approach can be used to assess and influence the development of new technologies right from the beginning and with sufficient certainty of direction?

Thirdly, who is responsible and competent to perform the evaluation on the sustainability performance of technologies and to make corresponding decisions concerning their future roadmap?

Ultimately, how can we transform technosphere and society to a culture of sustainability, in other words: “Can humanity adapt to itself?” (Toussaint et al., 2012)

In order to elaborate viable answers to these fundamental questions, this paper aims to review existing definitions of sustainability as well as approaches of sustainability assessment of technologies and associated tools within the era of the Anthropocene. Hence, it first addresses the issue of framing the term of sustainability in the era of the Anthropocene (section 2). Based on a brief overview in section 3 how sustainability assessment methodologies evolved in the past, major milestones and concepts with regard to the technology assessment (TA) framework are described in section 4, with particular focus on the concept of prospective TA. In section 5, we use the energy sector as an example to discuss how mirroring ongoing transformation processes in major areas of need can contribute to the further development of the TA framework. Finally, section 6 is dedicated to conclusions and outlook.

Sustainability in the Anthropocene

Sustainability is a delicate term. Its inflationary use in politics, science and society has rendered it increasingly arbitrary and often blurs the view of its core meaning. Sustainability as a concept was introduced more than 300 years ago by chief miner Hans-Carl von Carlowitz on the occasion of a serious raw material crisis: Wood, at that time the most important raw material for ore mining, had become noticeably scarce and without appropriate countermeasures, the operation of smelting furnaces and consequently silver production would not have been further possible within a foreseeable future. Driven by these economic requirements, von Carlowitz proposed a new principle of forest management, which envisaged taking only as much wood from the forests in a given period of time as could grow back again in the same period (Töpfer, 2013von Carlowitz, 1713).

In the discussions about the scarcity of natural resources in the 1970s (cf. Meadows et al., 1972), the concept of sustainability was taken up again and experienced a renaissance through its further development in terms of content. Environmental and social aspects of sustainability have been placed more and more in the foreground. Hence, sustainability has increasingly been understood as a major global transformation process (Grießhammer and Brohmann, 2015; see also section 5), which is reflected in particular in the term of a “sustainable development.” Another milestone in the framing of sustainability as a concept with normative relevance has been achieved in the World Commission on Environment and Development. In its report, the so-called “Brundtland Report,” the commission defines sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs” (World Commission on Environment and Development, 1987: without page). With this definition, the aspects of intra– and intergenerational equity were introduced and particularly emphasized in the sustainability debate. Furthermore, the “Brundtland Report” frames sustainable development as a necessary transformation process of economy and society as it points out that:

“Sustainable development is not a fixed state of harmony, but rather a process of change in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are made consistent with future as well as present needs” (World Commission on Environment and Development, 1987: without page).

Since the 1990s, the debate on how intergenerational justice is to be achieved has been dominated by two diverging perceptions of the concept of sustainability, referred to as “strong sustainability” and “weak sustainability”:

Strong sustainability postulates to preserve the entire natural capital of the Earth. Human capital and natural capital are perceived to be complementary, but not interchangeable. This means that humans, as users of nature, may live only from the “interest” of the natural capital. Any consumption of non-renewable resources would therefore be ruled out, and renewable resources could only be used within their regeneration rate (Som et al., 2009).

Weak sustainability calls only for preserving of the Earth’s total anthropogenic and natural capital. Accordingly, humanity could reduce natural capital to any degree if it was substituted in return by anthropogenic capital with the same economic value (Solow, 1986).

At the UN Conference on Environment and Development at Rio de Janeiro in 1992, the concept of sustainable development was recognized as an internationally guiding principle. The underlying idea was that economic efficiency, social justice and the safeguarding of the natural basis of life are interests that are equally important for survival and complement each other. Although 27 fundamental principles for sustainable development are enshrined in the Rio Declaration on Environment and Development (United Nations, 1992), for more than 10 years no concrete sustainability goals and indicators existed that would have been suitable in particular for the sustainability assessment of products and technologies.

With the adoption of the 2030 Agenda and its Sustainable Development Goals (SDGs) in 2015, the member states of the United Nations for the first time agreed upon a universal catalog of fixed time-specific targets. These 17 SDGs (see Figure 1) and the corresponding 169 targets can be considered as the interdisciplinary normative basis of sustainability research, covering all three dimensions of sustainable development, that is, environmental, economic, and social aspects (United Nations, 2015).

Figure 1. The 17 Sustainable Development Goals of the 2030 Agenda.Source: UNDP (2016).

The 2030 Agenda is universal in scope, which means that it commits all countries to contribute toward a comprehensive effort for global sustainability in all its dimensions while ensuring equity, peace and security. Furthermore, with its central, transformative promise “leave no one behind,” it is based on the principle to take on board even the weakest and most vulnerable. Hence, it seeks to eradicate poverty in all its forms as well as to combat discrimination and rising inequalities within and amongst countries (BMUV, 2022SDGF, 2016United Nations, 2021).

As a major specification of the 2030 Agenda, the concept of Planetary Boundaries focusses on the environmental dimension of sustainability. This approach put forward by Rockström et al. (2009) echoes the concept of “strong sustainability” (see above) and has been updated and extended by Steffen et al. (2015). At its core, it identifies nine global biophysical processes, whose significant changes can lead to conditions on Earth that are no longer considered a “safe operating space for humanity.” According to Steffen et al. (2015), several of the global biophysical processes are already beyond an uncertainty range with a high risk of dangerous changes on the planetary scale. These include the integrity of the biosphere (expressed as genetic diversity) and biogeochemical material flows, especially nitrogen and phosphorus. Others (e.g. climate change and land use change) are considered to be in an area of high uncertainty with an increasing risk of dangerous changes.

In 2016, Rockström and Sukhdev presented a new way of framing the SDGs of the 2030 Agenda. According to the concept of “strong sustainability” they argued that economies and societies should be perceived as embedded parts of the biosphere (Stockholm Resilience Center, 2016). This perspective is illustrated by the so-called “Wedding Cake” model (see Figure 2) and challenges the predominant understanding expressed by the “Three Pillars” model of sustainability (cf. Barbier, 1987) that environmental, economic and social development can be regarded as separate parts. Hence, the “Wedding Cake” model of sustainability can be understood as a combination of the 2030 Agenda and the concept of Planetary Boundaries since it calls for a transition toward a world logic where the economy serves society so that both economy and society can evolve within the “safe operating space” of the planet.

The link between SDGs and Planetary Boundaries is of paramount importance in the age of the Anthropocene. Even though the SDGs have been lauded for amplifying the global development agenda by including environmental, social and economic concerns, the 2030 Agenda remains committed to a growth-oriented development that potentially conflicts with keeping human development within the Planetary Boundaries as defined by Rockström et al. (2009). A striking example of the growth-oriented concept can be found in SDG target 8.1, which requires to “sustain per capita economic growth in accordance with national circumstances and, in particular, at least 7% gross domestic product growth per annum in the least developed countries” (United Nations, 2015). Against this background, substantial changes toward more sufficient consumption patterns that help to remain within the Earth’s environmental carrying capacity need to be established and promoted by setting corresponding political framework conditions (Fischer and Grießhammer, 2013).

Evolvement of sustainability assessment methodologies

The scientific methodology for assessing the sustainability of technologies, material or products is far less developed than the debate on sustainable development and sustainable consumption would suggest. However, initial approaches in this respect were developed by the Öko-Institut as early as 1987 (Öko-Institut, 1987). The concept of the Produktlinienanalyse (English “product line analysis”), representing a pioneering step in the development of methods for life cycle-based analyses, made it possible to record the environmental, economic, and social impacts of products along the whole product line.

Nevertheless, at the end of the 1990ies, the product-related Life Cycle Analysis (LCA) became established and standardized on the international level, representing a methodology which assesses only the environmental impacts of a product over its entire life-cycle. The decisive standards of LCA are ISO 14040 (2006) and ISO 14044 (2006), which have become widely applied. These international standards essentially describe the process of conducting LCAs, examining the impact of a product from “cradle to grave.” Particular attention is paid in ISO 14040 and ISO 14044 to the scoping of a LCA study, with concrete requirements on the choice of the system boundaries, the functional unit (i.e. the quantified performance of the investigated product system for use as a reference unit) and the data quality requirements. In addition, the performance of a critical review by an independent third party is envisaged as a quality assurance step.

Sustainability assessments, however, did not advance until the 2000s, with the detailed method descriptions PROSA (Product Sustainability Assessment) by the Öko-Institut (Grießhammer et al., 2007) and SEE-Balance (Socio-Eco-Efficiency Analysis) by the chemical company BASF (Kicherer, 2005Saling, 2016). Even for the sub-methods of Life Cycle Costing (Swarr et al., 2011) and Social Life Cycle Assessment (Grießhammer et al., 2006UNEP-SETAC Life Cycle Initiative, 2009), method descriptions were presented comparatively late. There are also proposals to combine the three sub-methods of Life Cycle Assessment, Life Cycle Costing and Social Life Cycle Assessment to form the Life Cycle Sustainability Assessment (LCSA) (Feifel et al., 2010Finkbeiner, 2011). However, in contrast to PROSA, the aim is not to analyze and evaluate needs and the realized product benefits, even though meeting basic needs through products is one of the central demands of Agenda 21. Whereas initially the sustainability of only relatively simple products such as food, textiles, or detergents had been assessed, in recent years the sustainability performance of complex products such as notebooks (Manhart and Grießhammer, 2006) and telecommunications services (Prakash et al., 2016) as well as emerging technologies and materials (Möller et al., 2012) has also been analyzed.

For many years, the comparatively open or specific selection of indicators for conducting sustainability assessment case studies was justified by the lack of a relevant normative framework as well as a generally accepted set of indicators. With the adoption of the United Nations’ 2030 Agenda in 2015, this has fundamentally changed (cf. section 2). In addition to its 17 SDGs and 169 targets, the 2030 Agenda provides a globally accepted system of indicators for measuring the SDGs. However, only a few dozen of the 169 targets explicitly refer to products and companies. In a recently completed research project (Eberle et al., 2021) funded by the German Federal Ministry on Education and Research a method was developed which provided for a reasoned restriction to those indicators to the achievement of which products, services and companies can actually contribute. By means of the method, it is possible for the first time to measure the contribution to the achievement of the SDGs at the level of products and services and thus to establish a link between LCA and SLCA results and the 2030 Agenda (Eberle and Wenzig, 2020). To complete the assessment, an in-depth analysis of societal benefits according to Möller et al. (2021a) can be supplemented, which is also based on the 2030 Agenda. In this way, additional benefit aspects of the products and services considered beyond their core benefits can be identified with a view to the SDGs.

As our experience from practice has shown, for the sustainability assessment of any object of investigation, the respective functionality is of utmost importance and must therefore be considered and defined in detail. In this context, a careful definition of the functional unit as defined in ISO 14040 and ISO 14044 is considered to be essential. In addition, a detailed analysis of the various benefit aspects of the studied object is recommended. Against this background, there is no technology, material or product that is sustainable per se. Only the way a technology, material or product is handled and used over its whole life-cycle may be more or less sustainable. Therefore, their sustainability performance always has to be analyzed and evaluated in the context of the intended application and with regard to a possible contribution to a sustainable development. Absolute statements such as “sustainable plastics,” often combined with the addition “due to recyclability,” must therefore be rated very critically. Recyclability, which is often regarded as synonymous with sustainability in the marketing of materials, depends on available recycling infrastructure, which typically only exists in the materials sector where it is economically viable.

Another important lesson learned from several decades of sustainability assessment is that assessment systems have changed and evolved significantly in the past. As sustainability assessment has been driven by emerging environmental risks, further developments in the normative framework and societal developments, the assessment methodology had to evolve as well. Notable examples of additions to the assessment methodology with respect to the environmental dimension of sustainability are the issues of greenhouse effect and ozone depletion in the 1980s and the microplastic problem in the recent past. It can be assumed that the aforementioned drivers will continue to influence sustainability assessment in the future. For a future-proof sustainability assessment methodology, it is therefore essential that newly emerging risks can be identified at an early stage. This calls for a flexible and adaptive assessment framework as well as an interdisciplinary exchange, especially between natural and social sciences (Möller et al., 2021b).

Evolvement of technology assessment

Roughly in the second half of the 20th century, undesirable side effects of progress in science and technology increasingly manifested themselves in the form of risks and concrete damaging events and thus found their way into the collective consciousness of society. The almost ubiquitous emergence of persistent pollutants like the pesticide DDT (Dichlorodiphenyltrichloroethane) in the environment and the risks of nuclear power can be regarded as particularly controversial examples in this respect (Carson, 1962Grunwald, 2019). Accordingly, the appearance of these phenomena is considered to mark the beginning of the Anthropocene era. As a result, a consensus previously largely in place, which equated scientific and technological progress with social progress, was increasingly questioned. Against this background, researchers were more and more confronted with the challenge of reflecting not only on the possible consequences of science-based technologies, but also on the epistemological foundations of their own actions (Kollek and Döring, 2012).

Consequently, the concept of TA became established in the 1960s, particularly in the United States, with early studies focusing on the issue of environmental pollution, but also issues like the supersonic transport, and ethics of genetic screening (Banta, 2009). One of the basic motivations of TA is to deal with possible short- and long-term consequences of scientific and technological progress (e.g. societal, economic, ethical, and legal impacts) as early and comprehensively as possible, in order to enable formative interventions (Grunwald, 20102019). The ultimate goal of early TA studies was to provide policy makers as primary target group with information on policy alternatives (Banta, 2009).

One of the key challenges for TA relates to the question of how to respond to emerging technologies, that is novel technologies that are still at an early stage of their development. Especially in the case of basic research-oriented R&D work, the new developments are characterized by low technology readiness levels (cf. Mankins, 1995), that is the R&D results are still relatively far away from entering the market in the form of tangible products. The relatively low maturity of the technologies results in a very limited availability of quantitative data on subsequent product specifications and potential environmental impacts. On the other hand, addressing sustainability aspects at such an early stage in the innovation process basically offers an excellent window of opportunity to avoid possible weaknesses with regard to sustainable development and to identify existing strengths. This situation is often referred as the Collingridge Dilemma (Collingridge, 1980): In the infancy of an emerging technology, the potential to influence its properties is particularly high, but the knowledge about its sustainability impacts is comparatively low. Later on, the understanding on the consequences of an emerging technology is expected to increase, yet the possibilities for shaping its design may already be significantly reduced by already existing path dependencies (see Figure 3).

Figure 3. Dependencies between the maturity of a technology, the knowledge about environmental, health safety and social (EHS/S) impacts as well as the ability to prevent corresponding risks.Source: Köhler and Som (2014).

Against this background, an ideal period for the assessment and eco-design of emerging technologies would be during the innovation stages of “applied technology development” or “product design.” In these stages, the ability to prevent sustainability risks is still relatively high (cf. curve with solid line in Figure 3) and, at the same time, the quantity and quality of data required for a sustainability assessment are increasing significantly. However, a sustainability assessment in the stage of “basic science and material research” is well before this ideal period.

Basically, the dilemma outlined by Collingridge presupposes a fundamental separation between cognition and action as well as between science and technology. With the emergence of the concept of “technosciences,” however, this hypothesis has been increasingly challenged since about the mid-1980s by postulating a constitutive relationship between science and technology (Haraway, 1997Hottois, 1984Latour, 1987). Hence, the characteristic feature of technosciences is a far-reaching convergence of science and technology on all levels of action and effect, of materiality and culture (Kastenhofer, 2010).

The concept of technosciences has been adopted by anthropologists, philosophers and sociologists in science and technology studies as well as in the field of philosophy of science (e.g. Hacking, 1983Nordmann, 2006Pickering, 1992). Other TA concepts attach less emphasis to the intertwining of science, technology and society, but rather aim to start TA as early as possible. These include the “constructive Technology Assessment” developed by Schot and Rip (1997), which does not focus primarily on the possible consequences of a technology but aims to assist in shaping its design, development and implementation process. In this context, it was also proposed that a “real-time assessment” should accompany technology development from the outset and integrate social science issues as well as policy and governance aspects at a very early stage (Guston and Sarewitz, 2002).

Nevertheless, the concept of technosciences generated important impulses to scrutinize and reconsider some of the central assumptions underlying many existing TA concepts. In this context, Liebert and Schmidt (2010) point out that the goals and purposes of innovation processes, which are often clearly articulated and recognizable in the context of technosciences, offer the possibility of unlocking knowledge about the respective technology development. Hence, they challenge the assumption of general knowledge deficits as stipulated by the Collingridge Dilemma. Furthermore, they argue that technosciences are usually developed and applied by many different actors. In this respect, the fiction of a control of technology (especially by political actors) as advocated in early TA concepts will increasingly shift to a paradigm of collaborative design.

Consequently, TA should be framed as a “Prospective Technology Assessment” (ProTA) and initiate phases of science- and technology-related reflection as early as possible:

“ProTA aims to shape technologies by shaping the goals, intentions and attitudes from the perspective of the anticipated consequences and realistic potentials” (Liebert and Schmidt, 2010: 114).

According to Liebert and Schmidt (2010), ProTA requires a normative framework that can be derived from the history of philosophical reflection. Concerning the underlying ethical criteria, two antagonistic principles are outlined: The “heuristics of fear” (Jonas, 1979) and the “principle of hope” (Bloch, 1959), which in combination serve as a mindset for shaping emerging technologies as well as technoscience as a whole and that entails four different types of orientation: human, social, environmental as well as future orientation.

Furthermore, ProTA is also strongly perceived as a participatory approach. In contrast to an observation from an external perspective (as practiced in earlier TA concepts), ProTA should become part of a of self-reflection and self-criticism among scientists and engineers within the R&D stage itself that also includes the perspective of societal and political actors (Fisher et al., 2006Liebert and Schmidt, 2010).

Discussion

As the evolutionary history of TA has shown, an early assessment of technologies and their impacts on environment and society is possible in principle. Despite of the epistemic limitations caused by the Collingridge Dilemma, the concept of ProTA provides a participatory and incremental self-reflection process that facilitates data acquisition even during the early stages of R&D and thus enables the shaping of technologies throughout the innovation process. One of the most important features of ProTA is a well-defined normative framework. Yet Liebert and Schmidt developed the associated criteria several years before the establishment of the 2030 Agenda. With its 17 SDGs and the 169 SDG targets, however, substantial opportunities have been created to concretize the normative framework of TA, especially with respect to a sustainable development. Hence, by referencing to the 2030 Agenda, a comprehensive sustainability assessment of technologies has become possible (Eberle et al., 2021Möller et al., 2021a). Even more than that, with the 2030 Agenda representing a globally accepted framework that all United Nation member states have committed themselves, sustainability assessment of technologies has become an obligation.

In order to ensure goal-oriented and future-proof assessments, TA methodology needs to be able to recognize changes regarding its assessment criteria at an early stage, as already pointed out in section 3. For early detection, the investigation of existing and predicted transformation processes plays an important role in this context.

Transformations can lead to structural paradigmatic changes at all levels of society, for example in culture, value attitudes, technologies, production, consumption, infrastructures and politics. The corresponding processes take place co-evolutionarily, simultaneously or with a time lag in different areas or sectors, and can significantly influence, strengthen or weaken each other. The decisive factor for a transformation is that those processes become more and more condensed over time and, in the sense of a paradigm shift, lead to fundamental irreversible changes in the prevailing system. Transformations can be unplanned or intentional, they can take several decades and proceed at very different speeds (Grießhammer and Brohmann, 2015).

In contrast to the non-targeted transformations of the past (such as the first and second industrial revolution), it is now presumed that intentional transformations (e.g. the “Energiewende,” i.e. the transition of the energy system in Germany) can be significantly influenced and accelerated in a desired direction, but nevertheless not controlled in detail. This assumption is based on the recently available knowledge and experience of complex control, governance and strategy approaches (Grießhammer and Brohmann, 2015). The fundamental possibility of influencing or even controlling transitions is expressed by the term “transition management” (Kemp and Loorbach, 2006).

For understanding transition management, a multi-level perspective is fundamental. Accordingly, three different levels exist in each system under consideration, referred to as niches, regime, and landscape, with interactions between these levels (see Figure 4).

Figure 4. Multi-level perspective of transition management (Grießhammer and Brohmann, 2015; modified based on Geels, 2002).

At the level of the prevailing regime, Grießhammer and Brohmann (2015) distinguish eight fields of action or sub-systems of society in which transformative innovations and initiatives can influence each other or proceed in a co-evolutionary manner. These eight fields of action are defined as follows:

Values and models: normative orientations such as values, socially or legally formulated goals, guiding principles or ideas for society as a whole or for individual areas of need (e.g. “Limits to Growth” according to Meadows et al., 1972);

Behaviors and lifestyles: individual and society-wide shared (consumption) actions, everyday practices and habits, which can often deviate significantly from values and consciousness (e.g. dietary habits);

Social and temporal structures: social and culturally determining structures (such as different gender roles or demographic shifts) as well as temporal factors (such as the duration of the transformation, windows of opportunities or diffusion processes of innovations);

Physical infrastructures: permanent material structures that influence or even dominate the action spaces for groups of actors (e.g. road network);

Markets and financial systems: market structures (e.g. degree of concentration, globalization) and market processes such as supply, demand and prices of goods and services;

Technologies, products, and services: individual products and services as well as overarching technologies that can act as a key driver of transformations;

Research, education, and knowledge: science, research and development in practice as well as their institutional constitution, appropriate educational measures at various levels as well as knowledge stocks required for transformations;

Policies and institutions: control instruments such as commandments and prohibitions, financial incentives or informational instruments, as well as the associated institutional and organizational framework (e.g. state bodies, competencies, separation of powers, course of the democratic process and legal framework).

The analysis of the determining factors of a transformation process and their possible impact on the method of sustainability assessment of technologies shall be exemplified by the transformation in the energy sector representing an area of need where general principles for the sustainability assessment of technologies have already been formulated (cf. Grunwald and Rösch, 2011). The following table summarizes the findings from this exercise and provides an overview of the determining factors for the fields of action in the energy sector. In this respect, it has to be noted that the scope of the investigation refers to the specific situation in Germany.

Many of the identified determining factors for the fields of action are transformation processes themselves. Digitalization, for example, is coupling the energy transition with the ongoing industrial revolution in information and communication technologies. Furthermore, the transition of the energy sector influences the energy supply for the transport system as well as for the building stock, and vice versa. The parallel transformations can influence, support, or hinder each other. For example, electromobility generates a higher demand for renewable electricity; on the other hand, the batteries installed in cars provide a storage option for electricity. In this context, it is also important to consider the various and partly rivaling innovations emerging from niches (cf. Figure 4). These include e-cars, for example, but also fuel cell cars and e-bikes as a fundamental alternative. The same is applicable for phenomena at the level of the greater landscape: The efforts of an increasing number of companies to achieve climate neutrality play an eminently important role here, as the demand for renewably generated energy will continue to grow significantly. However, the current consequences and long-term effects of the Corona pandemic could lead to significant energy savings through a reduction in air travel, at least in the short to medium term.

The concept of ProTA is currently implemented in the Cluster of Excellence “Living, Adaptive and Energy-autonomous Materials Systems” (livMatS) funded by the German Research Foundation. The vision of this cluster is to develop novel, bioinspired materials systems, which adapt autonomously to their environment and harvest clean energy from it. The research and development work in livMatS aims to provide innovative solutions for various applications, particularly in the field of energy technologies. Sustainability, psychological acceptance and ethical approval form essential claims of the work done in livMatS. Therefore, prospective reflection of the sustainability aspects as well as research into consumer acceptance and social relevance of the developed material systems form an integral part of livMatS work right from the very beginning (livMatS, 2022).

The prospective TA of the technologies and materials to be developed in the livMatS cluster is designed as a tiered approach called TAPAS (Tiered Approach for Prospective Assessment of Benefits and Challenges). The ultimate goal is the design of a new development-integrated sustainability assessment framework that starts with interactive early tools on a qualitative basis (e.g. questionnaires and prospective chemicals assessment) and also covers quantitative case studies. Development-integrated assessment entails that the methodology both encourages and enables the innovators themselves to carry out assessments on sustainability, ethics and consumer issues as part of the innovation process (Möller et al., 2021c).

With regard to the livMatS materials, the ongoing transformation in the energy sector has considerable influence on the potential application fields: In their efforts to become climate-neutral, companies will make much greater efforts to harness previously unused (waste) energy. Energy harvesting in industrial processes as well as in the mobility sector and in buildings will consequently gain considerably in importance and may become common practice. For example, due to progress in digitalization, there will be more and more sensors at peripheral locations requiring power supply. Moreover, prosumers may also find it attractive in the future to feed harvested energy of their own solar systems into the grid, especially at times of high energy prices.

For the methodology of the prospective sustainability assessment, however, no fundamentally new issues can be identified on the basis of the available findings, which could not be captured by the existing toolbox. This can be justified with a closer look to the relevant technological approaches (digitalization, hydrogen technology, energy harvesting) presented in Table 1, as their respective designs do not reveal any radically new materials and process configurations. This assessment, however, needs to be subject to continuous review as the new material systems mature. Furthermore, it should be noted that for sustainability assessments in living labs and citizen science projects, instruments are required that provide meaningful and consistent results even when used by laypersons. In this context, a tiered approach as described in section 4 is also expected to be beneficial.Table 1. Determining factors for the fields of action in the energy sector.

Conclusions and outlook

In light of the findings and the results of the previous sections, the four fundamental questions from the introduction will be revisited and answered as far as possible.

With regard to the first question, it could be demonstrated that universal and absolute statements on the sustainability of technologies are just as misleading as they are for materials or products. Possible contributions to a sustainable development can only be discovered in a case-by-case analysis of the entire product-line and in the context of the functionality and benefits of the object under investigation.

Secondly, an early and prospective assessment of sustainability of technologies requires a flexible and tiered approach. In this respect, we reference the TAPAS framework that aims to establish a new tiered development-integrated assessment methodology within the livMatS Cluster of Excellence. To enable assessments at an early stage and with sufficient certainty of direction, TAPAS starts with interactive early tools (e.g. questionnaires and prospective chemicals assessment) which are incrementally underpinned with quantitative case studies in an iterative process. In order to ensure an agile, goal-oriented and future-proof evaluation system, TAPAS also includes a careful reflection of ongoing transformation processes in application sectors (e.g. the energy sector) that are relevant to the technology. The prospective mirroring of the determinants of transformation processes of related areas of need as described in section 5 aims to provide a further feature for the continuous refinement of the TA framework, especially with regard to ProTA.

As of third, the assessment of the sustainability performance of technologies should include much greater involvement of those actors who are particularly good at overseeing and influencing the innovation process—the innovators themselves. To ensure sufficient feedback with society, science has to open up to the public and the participation of society in the sense of transdisciplinary research. In this respect, initial assessments of the technology developers need to be discussed in real laboratories, that is, open-innovation environments that focus on cooperation between science and the public in an experimental environment. Hence, suggestions from society should in return become part of the innovation process (Möller et al., 2021b).

Ultimately, in order to give humankind a chance to adapt to itself (Toussaint et al., 2012), technology and society need to co-evolve. Global agreements on normative goals such as the Sustainable Development Goals of the 2030 Agenda form a good starting point in this respect. For a culture of sustainability, however, policy should promote cooperation between actors for societally desirable transformation processes to a much greater extent. Equally important is a “greening” of ongoing transformations that are not induced by environmental policy (Grießhammer and Brohmann, 2015). The need to foster cooperation can be illustrated by the example of the energy transition: Driving forces for the “Energiewende” can already be found in all stakeholder groups, that is in civil society and governmental actors, but also in science and companies. Unfortunately, however, these players in many cases still act independently of each other. Instead, earlier and greater involvement of business and industry in ongoing transformation processes, support for new business models, and greater international cooperation would be needed.

Abstract

Much scientific debate has focused on the timing and stratigraphic signatures for the Anthropocene. Here we review the Anthropocene in its original usage and as it has been imported by anthropology in light of evidence for long-term human-environment relationships. Strident debate about the Anthropocene’s chronological boundaries arises because its periodization forces an arbitrary break in what is a long-enduring process of human alterations of environments. More importantly, we argue that dividing geologic time based on a “step change” in the global significance of social-environmental processes contravenes the socially differentiated and diachronous character of human-environment relations. The consequences of human actions are not the coordinated synchronous product of a global humanity but rather result from heterogeneous activities rooted in situated sociopolitical contexts that are entangled with environmental transformations at multiple scales. Thus, the Anthropocene periodization, what we term the “Anthropocene divide,” obscures rather than clarifies understandings of human-environmental relationships.

Since the Anthropocene’s formulation by atmospheric chemist Paul Crutzen and ecologist Eugene Stoermer (2000) to recognize a new period of geologic time marking human transformations of Earth’s environmental systems, the designation has been taken up vociferously across the academy. From Earth scientists to literary critics, scholars now debate the usefulness of distinguishing an Anthropocene from the Holocene, the currently recognized geological epoch spanning the past 11,600 years since Earth’s last glaciation (e.g., Autin and Holbrook 2012; Braje 2016; Finney and Edwards 2016; Lewis and Maslin 2015; Waters et al. 2016a; Zalasiewicz et al. 2015). The implications of this designation have also been discussed as a framing concept for environmental governance (e.g., Biermann et al. 2016; Moore 2016; Purdy 2015; Ribot 2014) and as a way of disrupting the long-held distinction between natural history and human history (cf. Chakrabarty 2009; Malm and Hornborg 2014; Mikhail 2016). The Anthropocene is thus a potentially revolutionary concept—not just because it has become synonymous with the unprecedented global environmental impacts of humans but also because it implies an end to basic frameworks of science, society, and scholarship that have long guided Western intellectual thought (e.g., Latour 2004). As the philosopher of science Bruno Latour (2014) has noted, it subverts traditional conceptions of an external objective world devoid of humans, given that human “action is visible everywhere—in the construction of knowledge as well as in the production of the phenomena … sciences are called to register” (6, italics in the original). Such statements underscore the need to evaluate how we understand human social action in the context of an Earth transformed by humans, especially in relation to anthropological concerns for historical relationships among humans, other organisms, and the material processes and associated discourses that give shape to environments.

While the Anthropocene has rightly called attention to a suite of grave global environmental consequences related to human activities, the various emphases among scholars now using the designation have also reoriented the concept in multiple directions, many of which work at cross-purposes from each other. For instance, while some argue that the concept dissolves the great binary between society and nature—“the end of the division between people and nature” in the words of environmental historian Jedediah Purdy (2015:3; see also McKibben 1989)—others emphasize its binary foundations, stressing, for example, that humans are now “overwhelming the great forces of nature” (e.g., Steffen, Crutzen, and McNeill 2007). The Anthropocene has become a differential lens through which disciplines across the academy are reviewing, debating, and reinventing their conceptions of humanity and nature.

Below we address the Anthropocene concept from a perspective more directly related to its original framing—asking foremost how the concept and geological time period might both constrain and enable scholarly understandings of human-environment relationships. To do so, we review the term’s broader usage in light of archaeological and ecological evidence on long-term relationships among humans and the environments they both inhabit and produce.

Strident debate about where to place the Anthropocene’s chronological boundaries arises—with the mid-twentieth or late eighteenth century being the most commonly advocated among others (cf. Crutzen 2002; Lewis and Maslin 2015; Ruddiman 2013; Smith and Zeder 2013; Waters et al. 2016a; Zalasiewicz et al. 2015)—because the Anthropocene’s periodization forces scholars to apply an arbitrary break in what is a lengthy process of human modifications to both local and planetary environmental conditions. There should be no doubt that the magnitude of human influence on Earth’s environmental systems has intensified alarmingly since the Industrial Revolution and particularly since the 1950s (e.g., Steffen, Crutzen, and McNeill 2007; Waters et al. 2016a). Nevertheless, an Anthropocene periodization that begins at these points fundamentally obfuscates qualitative similarities and historical linkages with the dynamics of human-environmental relationships in previous periods (e.g., Boivin et al. 2016; Braje 2015; Braje and Erlandson 2013; Erlandson and Braje 2013; Kirch 2005; Moore 2015; Ruddiman et al. 2015; Smith and Zeder 2013). To understand the role of human activities in transforming Earth, it is essential that these not be conceived as a binary distinction—before versus after—but rather as a continuously changing process, which necessarily calls attention to a variety of differentiated actors and historical, cultural, political, and ecological contexts. The challenge of the Anthropocene proposal is not simply its formal division of geologic time but also the need to call attention to the entanglements through which social relationships, inequalities, and environmental histories are continually unfolding and producing novel Earth trajectories.

The Anthropocene(s)

To contribute usefully to the Anthropocene conversation, it is critical to differentiate what the designation has come to mean among the various academic fields that have taken it up. The Anthropocene’s multiple referents (e.g., as marker of anthropogenic stratigraphic materials, as period in which Earth’s climatic and environmental workings have been shaped by humans, as the end of the division between society and nature) have allowed it to be adopted with a variety of different emphases among scholars of the natural sciences, humanities, and social sciences. Ironically, many of these framings work at cross-purposes from one another, a point we stress in arguing that the Anthropocene divide obscures understandings of the long-term dynamics of human-environment relationships.

For many scholars of the humanities and social sciences, the Anthropocene stands in for a dark period of human-environment relationships associated with modernity and the outgrowth of the Eurocentric belief in the divide between nature and humanity that now “catastrophically affects the destinies of all—plant, animal, and human—through global warming and mass extinctions” (Carrithers, Bracken, and Emery 2011:663). Environmental historian Ian Miller (2013), for example, has specifically argued that the Anthropocene be considered coeval with the development of “ecological modernity.” Yet, by highlighting humans’ current roles in shaping planetary conditions, the Anthropocene has largely come to signify a period in which this great divide is now obsolete. In environmental imaginaries and historiographies, it is a period that is “after nature” (Purdy 2015:3). Thus, for many anthropologists it represents the dissolution of the long-standing modernist binary that has structured understandings of human social life in distinction from a separate natural world. The Anthropocene has also engaged anthropologists in critically evaluating how the natural sciences represent humans as a single entity—that is, the species (cf. Bauer and Bhan 2016; Carrithers, Bracken, and Emery 2011; Gibson and Venkateswar 2015). The emphasis on the human species as a “geophysical force” has allowed some scholars to raise foundational epistemological and ontological questions about the nature of history, historical subjects, and the world humans inhabit. For instance, by signaling a period of human-caused global environmental change, the Anthropocene has spurred a philosophical recognition of phenomena and objects (e.g., climate) that are beyond, or at least challenge, human perception and experience (e.g., Morton 2013). In this way, the Anthropocene has disrupted historiography in this new period and how the ontological relationships between subjects and objects, the constitution of social actors, and the mediation of perception and historical imagination are theorized (cf. Chakrabarty 2009; Latour 2014; Mikhail 2016; Morton 2013; see Bauer and Bhan 2018).

Among the natural sciences, the Anthropocene has come to more strictly reference a period during which humans now dominate the “great forces of nature” (Steffen, Crutzen, and McNeill 2007) or rather, as the environmental scientists William Ruddiman and colleagues (2015) have characterized it, when humans have “replaced nature as the dominant environmental force on Earth.” Earth system science (ESS) views Earth as a system of interacting “spheres”—the atmosphere, lithosphere, hydrosphere, and biosphere—and uses Earth system models to describe the long-term dynamics of Earth’s interacting physical, chemical, and biological processes (Schellnhuber 1999; Steffen, Crutzen, and McNeill 2007). By connecting human history with ESS, this work helped build a foundation for assessing the most critical scientific claim of the Anthropocene narrative: that human activities have substantially changed the functioning of the Earth system. While evidence of human alteration of local environments has long been widespread, the claim that humans are altering the functioning of Earth as a whole has now been confirmed by a wide array of observations, perhaps most prominently by long-term trends in atmospheric carbon dioxide and their coupling with human combustion of fossil fuels and other alterations of the global “biogeochemical” cycling of carbon that are causing global changes in climate. These global changes are now potentially forcing the Earth system to undergo an irreversible step change or regime shift (tipping point) from a Holocene-like climate state to an Anthropocene climate state (Steffen, Crutzen, and McNeill 2007; Steffen et al. 2016; Waters et al. 2016a).

In these frameworks the Anthropocene is seen to demarcate a shift from humans as merely agents of local ecological changes to agents of geophysical history that are capable of affecting all planetary life by modifying the Earth system (cf. Chakrabarty 2009; Hamilton 2015; Morton 2013:7; Steffen, Crutzen, and McNeill 2007). Unsurprisingly, the Earth systems scholarship from which the term largely emanates has also focused on the Anthropocene’s utility in confirming humans’ planetary impacts within the stratigraphic systematics of the Geologic Time Scale maintained by the International Commission on Stratigraphy—that is, how humans’ global physical environmental impacts produce an unambiguous and permanent signature in Earth’s lithological and sedimentary records (e.g., Steffen et al. 2016; Vince 2011; Waters et al. 2016a; Zalasiewicz et al. 2015). On these lines, scientific debate focuses on where to place the Anthropocene’s stratigraphic boundary, or “golden spike.” The mid-twentieth or late eighteenth centuries are the most commonly advocated among a slew of other suggestions, including the “Orbis spike” of 1610, the mid-Holocene rise of agricultural land clearing, using the term to apply to the entirety of the Holocene, and even the megafaunal extinctions of the late Pleistocene (e.g., Braje and Erlandson 2013; Crutzen 2002; Erlandson and Braje 2013; Hamilton 2015; Lewis and Maslin 2015; Smith and Zeder 2013; Waters et al. 2016a; Zalasiewiz et al. 2015).

It is important to stress that proposals for formalizing the Anthropocene as a new epoch are based on three different forms of evidence that are not all applicable to the analytical framing of the Anthropocene by humanities and social science scholars noted above. Formal geological time periods are delimited through the identification of Global Boundary Stratotype Sections and Points (GSSPs or “golden spikes”) or the identification of Global Standard Stratigraphic Ages (GSSAs; Zalasiewicz et al. 2015). While both GSSPs and GSSAs are commonly used to mark geologic time transitions, GSSPs require the identification of a physical marker in a specific stratigraphic sequence of rocks, sediments, ice, or other layered materials, while GSSAs are simply chronologic times selected to mark significant changes in the Earth system. For example, Zalasiewicz et al. (2015) proposed to use radionuclide deposits from atomic bomb testing as a potential Anthropocene GSSP and recommended the precise timing of the first atomic bomb test be used as an Anthropocene GSSA. ESS presents a third form of evidence by identifying major shifts in Earth system functioning as an Anthropocene state transition (Steffen et al. 2016). While the first two approaches (GSSP and GSSA) are concerned with identifying anthropogenic strata or significant historical events, the last is concerned with environmental processes.

It should already be clear that these different designations should not be conflated. While a stratigraphic designation (GSSP) might serve as a practical reference for geological systematics to order sediments, the other (ESS) is a reference to the historical behavior of the relationships among Earth’s various interacting “spheres”—the atmosphere, lithosphere, hydrosphere, and biosphere—that have been similarly categorized for heuristic and analytical purposes. In that sense, only this last mode of designation is primarily concerned with understanding long-term relationships among human inhabitants and the workings of the Earth system. It is also the only Anthropocene designation that speaks directly to the concerns of humanities and social science scholars for the period’s dissolution of natural history and human history or for assessing the species as a “geophysical actor.” Indeed, ESS is foundationally concerned with how human activities both are embedded within and help to constitute the Earth system (e.g., Schellnhuber 1999). By way of contrast, stratigraphers concerned with GSSP designations might usefully categorize a new geological period by the presence of plastics and Styrofoam in sediments, just as an archaeologist of South India might identify the Iron Age by the presence of Black and Red Ware ceramics (e.g., Thapar 1957); yet neither stratigraphic designation necessarily implies an ontological shift in human-environment relationships. Moreover, the GSSP need for stratigraphic identifiers to mark globally synchronous Earth changes, rather than diachronous changes that typify historically specific environmental changes, prohibits the application of GSSPs to characterize more gradual and accumulative human alterations across Earth’s surface (Edgeworth et al. 2015; Ruddiman et al. 2015; Turner et al. 1990).

Periodization criteria for Anthropocene formalization in the Geologic Time Scale are thus clearly problematic for understanding long-term human environment relationships. Yet, it is worth stressing that the most literal translation of its etymology in scientific nomenclature references the “recent age” (cene) of “humans” (anthropos). Indeed, the Anthropocene concept appears first and foremost as a temporal designation—a period during which scholars recognize humans’ emergence as a “great force of nature,” the end of the division between society and nature, or the global presence of stratigraphic material evidence produced by the anthropos. Considering that the Anthropocene is at root a chronological designation about human activities and their relationships to the global environment, one might expect that anthropology would have had input into its formulation.

An Archaeology of the Anthropocene

It is remarkable that the scholarly discipline most focused on long-term changes in human-environmental relationships has been one of the most peripheral to discussions on the Anthropocene. As archaeologist Keith Kintigh and colleagues (2014) have recently noted, archaeology has hardly contributed to the formulation of the Anthropocene concept. Many of the early canonical pieces that defined the Anthropocene cite little or no archaeology (e.g., Crutzen 2002; Crutzen and Stoermer 2000). Indeed, its principal advocates over the last 15 years were largely natural scientists who stressed humans’ unique species-level effects on the Earth system over the last few centuries, largely dismissing the archaeological record of prehistoric periods as insignificant. While some of these foundational papers included historical scholarship in support of their claims of the uniqueness of environmental systems following the Industrial Revolution, they did not substantially rely on archaeological evidence. In fact, the pioneering work of Ruddiman and colleagues is the exception that seemingly proves the rule in this characterization: Ruddiman (2003) seriously considered the archaeological record to argue that prehistoric human agricultural activities greatly affected the climatic history of Earth by at least the middle Holocene but was generally dismissed early on by some of the more strident advocates of the Anthropocene (e.g., Ruddiman 2007; Ruddiman et al. 2016; Steffen, Crutzen, and McNeill 2007). This is not to suggest that early proponents of the Anthropocene did not have some general understanding of an archaeological record for long-term environmental change; clearly they did (e.g., Steffen, Crutzen, and McNeill 2007). However, the Anthropocene’s emphasis on humanity’s large-scale planetary effects allowed many scholars to easily overlook the archaeological and ecological evidence for pervasive long-term, human-related environmental changes that were tied to specific places or regions. As more recent scholarship on the Anthropocene has begun to incorporate regional archaeological records for human-related environmental histories, proponents of the Anthropocene have been forced to confront the difficulties of clearly demarcating it temporally (cf. Boivin et al. 2016; Braje and Erlandson 2013; Butzer 2015; Crumley et al. 2015; Edgeworth et al. 2015; Erlandson and Braje 2013; Rosen et al. 2015; Ruddiman et al. 2015). Indeed, the archaeologist Karl Butzer (2015) has suggested that the Anthropocene should be considered an “evolving paradigm.” Yet an emphasis on global-scale changes has continued to allow many scholars to explicitly argue that anthropologists, archaeologists, paleoecologists, and others building on place-based and regional environmental evidence have little to contribute to Anthropocene scholarship (e.g., Hamilton 2015). This position is untenable.

If the Anthropocene is an “evolving paradigm,” it is because its formulation depends on several underlying ontological challenges that require an anthropological and ecological intervention. To begin with, much of the Anthropocene literature reproduces the very dichotomy of nature and society that many scholars suggest it dissolves, separating one recent period during which the two realms could be usefully held apart from another more recent period in which they cannot. Such scholarship inherently perpetuates the natural-cultural distinction and also ignores historical and cultural diversity of human-environment conceptualizations; if, for instance, the Anthropocene represents a period in which people no longer acknowledge a clear divide between nature and society, as some argue, then many people were living in it well before Western scientists designated the period (e.g., Bradley 2000; Escobar 1999; see Bauer and Bhan 2018 for discussion). Moreover, in singling out the agency of humans as a “geophysical force,” the Anthropocene narrative also “silences” (sensu Trouillot 1995) a wide variety of social distinctions and landscape histories that are critical to contemporary understandings and experiences of socio-environmental conditions. In attributing climate change to humanity as an homogenous actor or species, it obscures underlying social differences and “asymmetries related to both the production and experience of environmental circumstances” and associated vulnerabilities (Bauer and Bhan 2016:66; Malm and Hornborg 2014; Ribot 2014; Sayre 2012). This is the case even as the most common proposals for marking the Anthropocene highlight decidedly Eurocentric drivers of Earth and human history, such as the invention of the steam engine (see discussion in Crossland 2014; Morrison 2015).

Humans, of course, do not modify global environmental systems by acting as an undifferentiated and homogeneous web, network, or species. They do so as socially, culturally, ecologically, and geographically situated and differentiated actors that have long been documented by archaeologists, cultural anthropologists, ecologists, and geographers (e.g., Bauer 2015a; Bauer and Bhan 20162018; Crumley 1994; Ellis 2015; Witmore 2014). Moreover, there can be little debate that humans who facilitated the production of greenhouse gases and global warming that originally inspired the Anthropocene designation have done so unequally and in different ways in different times. Crutzen (2002:23) himself recognized this early on: “these effects have largely been caused by only 25% of the world population.” This remains equally true today, with recent US per capita carbon dioxide emissions a full order of magnitude greater than those of India, for example (17 vs. 1.7 metric tons; World Bank 2015). Moreover, human-related climate change likely has early roots in land clearance and fire use in the early Holocene and perhaps even in the mass extinctions of megafauna across continents through the actions of late Pleistocene hunter-gatherers (cf. Braje and Erlandson 2013; Doughty 2013; Ruddiman et al. 20152016). Though a recent Anthropocene periodization might call needed attention to humans as agents of contemporary climate change, it does so while potentially obscuring historical processes and social differences related to the production of environmental changes at local, regional, and global scales over multiple time horizons.

Anthropocene narratives also risk downplaying the many nonhuman materials, things, and organisms that people are entangled with and that also contribute to climate and other global environmental changes through a variety of relationships. As the historian Dipesh Chakrabarty (2009) reminds us, humans have always been “biological” agents who shaped their environments, both collectively and as individuals. What sets the Anthropocene apart from previous periods for many scholars is that humans are now historiographically geophysical or “geological” agents. Yet, the distinction between humans as “biological” agents of ecology versus humans as “geological” agents of climate that arguably warrants the designation Anthropocene needs critical discussion, as it imagines a realm of geophysics somehow disconnected and separate from the biological world in the past. Ironically, the functional interconnections among humans—and all living organisms—and “the spheres” is a fundamental precept of ESS (Schellnhuber 1999).

Differences between humans as agents of “biology” and “geology” are not clearly differences in kind. There should be no doubt that people utilizing contemporary fossil-fuel technologies are transforming Earth’s climate, marking them as geophysical actors when considered within the broader assemblage of material relationships that affect greenhouse gases. Yet this should not preclude other people, dependent largely on human labor in clearing land and releasing carbon, for example, from being considered “geological” actors, relegating them to mere “biological” or ecological roles. It is not difficult to see such a position slipping into the problematic historiographical divide between “modern” and “primitive” people, differentiating people that are now capable of transcending the confines of nature to alter their environmental circumstances from those of previous times (Bauer and Bhan 2016). Moreover, such a distinction between biological and geological agents ignores basic ESS, in which the dynamics of diverse bacteria, plants, and other species are coupled with and alter the composition and functioning of Earth’s atmosphere, lithosphere, and climate systems (Ruddiman et al. 2016; Schellnhuber 1999). To identify any one of these as a geophysical agent to the exclusion of others is to ignore the numerous interactions among Earth’s organisms that constitute the biosphere and their coproduction of atmospheric conditions and climate. Thus, to address when any organism, human or nonhuman, affects geophysical conditions is to also address how they are enmeshed historically within the material relationships of ecologies and geographies that contribute to atmospheric conditions. Humans—and other species—began altering greenhouse gas concentrations in the atmosphere long before the invention of the steam engine (e.g., Ruddiman et al. 2016).

The Historical Ecology of Geophysical History

ESS is founded on the principle that interactions among the atmosphere, lithosphere, hydrosphere, and biosphere together with the external forcings of solar irradiance form a complex system that contributes to the processes of climate change, the global biogeochemical cycling of many elements, and other dynamics of the Earth system (Schellnuber 1999). Actively growing trees, for example, sequester carbon dioxide from the atmosphere that on release through combustion or decomposition contribute to greenhouse gas concentrations and therefore alter climate and the growth of other trees through feedback interactions (Archer and Rahmstorf 2010; Barford et al. 2001; Flannery 2005; Vavrus, Ruddiman, and Kutzbach 2008). On geologic timescales, the oxygenation of the atmosphere during the Proterozoic eon (ca. 2.5 bya) by cyanobacterial photosynthesis profoundly and permanently altered Earth’s atmosphere and climate over hundreds of millions of years—a geophysical and geochemical state shift produced by biological relationships and an example of niche construction; atmospheric oxygenation produced the ozone layer, shielding Earth’s surface from harmful ultraviolet radiation, making Earth’s land habitable to multicellular organisms for the first time (Erwin 2008). This process also reduced concentrations of methane and triggered a period of global glaciation (cf. Frei et al. 2009; Kopp et al. 2005). These examples demonstrate that biological agents inherently also function as geophysical and geochemical agents in the Earth system, as the term biogeochemical implies.

Early members of the genus Homo arguably developed abilities to alter the atmosphere with the use of fire hundreds of thousands of years ago when set within the context of biogeochemical assemblages (cf. Albert 2015; Roebroeks and Villa 2011). Moreover, human activities were likely related to mass extinctions of a range of land animals with a cascade of profound consequences for ecosystem functioning across Australia around 50,000 years ago and later elsewhere in the world (cf. Barnosky 2008; Boivin et al. 2016; Braje and Erlandson 2013; Grayson 2001; Kirch 2005; Miller et al. 2005; Rule et al. 2012). In the Holocene, intensified forms of land use associated with agriculture, animal husbandry, and human population and settlement growth reshaped animal populations, vegetation communities, and the ecological and geomorphic trajectories across large regions of the globe (e.g., Alizadeh et al. 2004; Bauer 2014; Boivin et al. 2016; Casana 2008; Conolly et al. 2012; Ellis 2011; Ellis et al. 2013; Erlandson and Braje 2013; Fuller et al. 2011; Morrison 2009; Rosen et al. 2015; Wilkinson 2003). These data alone have supported multiple suggestions that the Holocene has “long been the Anthropocene” (Morrison 2013:23; see also Braje 2016; Certini and Scalenghe 2015; Erlandson and Braje 2013; Smith and Zeder 2013). While archaeological research has focused on humans’ roles in local and regional ecological and geographical histories, as opposed to a global role as geophysical agents in a coupled “human-Earth” system, a few examples from the archaeological literature amply demonstrate the significance of assemblages of humans and nonhumans in creating climatic and other environmental conditions at global scales, problematizing claims of a newly emergent “geophysical” effect associated only with industrialization.

Prehistoric expansion of rice agriculture, irrigation, and pastoralism likely caused a reversal in atmospheric levels of methane, a greenhouse gas that decreased in the first half of the Holocene but then increased after ca. 5000 years ago (cf. Fuller et al. 2011; Ruddiman and Thomson 2001; Ruddiman et al. 20082016; Vavrus, Ruddiman, and Kutzbach 2008). Fuller et al. (2011) have argued that archaeologically estimated increases in rice cultivation and livestock pastoralism in South and East Asia correlate with rises of atmospheric methane documented in Greenland ice cores. This correspondence has allowed a growing cadre of climate scientists to convincingly argue that “the anthropogenic greenhouse era began thousands of years ago,” as per Ruddiman’s increasingly well-supported “Early Anthropogenic” hypothesis (Ruddiman 2003).

Yet crucial to our broader point, both prehistoric and contemporary environmental transformations and their effects cannot be attributed equally to all members of these societies. Neolithic and Iron Age inhabitants of South India, for instance, differentially participated in agropastoral activities that produced methane and large-scale geomorphological transformations, such as soil erosion, and these differences were related to the development of status distinctions and social inequalities (e.g., Bauer 20142015a2015b; Sinopoli 2013). Moreover, early irrigated rice cultivation across large areas of South and East Asia was likely a highly politicized practice; there is strong evidence that not all inhabitants had access to irrigation facilities for growing rice and that irrigated and dry-farmed cultigens had differences in productivity, value, and symbolic uses in many precolonial contexts (e.g., Bauer and Morrison 2008; Ellis and Wang 1997; Huang 1990; Morrison 2009). Thus, even in these preindustrial periods, the historical ecology of geophysical history was also a political ecology, a point that is critical to recognize if we are to understand and engage actively with the long-term entanglements between cultural practices, social relationships, and the material workings of Earth. To understand the historical degree to which human activities have altered Earth systems thus requires that the full assemblage of processes and actors be considered and, equally important, the differences among them.

Discussion: The Anthropocene Divide and the Social Environment

Different designations of the Anthropocene direct scholarly attention toward different things—a stratigraphic marker (GSSP), a global historical event indicating a new “age” (GSSA), and the historical behavior of relationships among Earth’s various “spheres” of interaction (ESS). Only the latter, the Anthropocene formulation of Earth system scientists, is primarily concerned with understanding long-term relationships among humans and the workings of Earth’s climate and other systems. In that sense, it is also the only Anthropocene designation that speaks directly to the concerns of humanities and social science scholars for the period’s dissolution of natural history and human history or for assessing the species as a geophysical actor. Yet, as we demonstrated above, humans have been participants in Earth’s biogeochemical processes for thousands of years, and their influence on geophysical and climatic conditions likely significantly predates the most common chronological proposals for the Anthropocene. In short, there is not, and could never be, a clear date at which humans became “geophysical.” To be biological is also to be geophysical. Thus, the degree to which humans have influenced climate must necessarily be considered as a dynamic long-term process, a process that we have argued above and elsewhere is also deeply enmeshed in a political ecology—that is to say, how social affiliations, differences, and inequalities are also produced and reconstituted.

For these reasons, proposals for an Anthropocene periodization—for a geological divide between the “recent age” of humans and that which preceded it—significantly constrain historical understandings of human-environment relationships, including the recent processes and histories that have shaped contemporary contexts and the increase in human effects on global warming over the last few centuries. Thus, we are in agreement with other scholars who have recently sought to supplant the designation Anthropocene with other terms that critically represent the sociohistorical processes that are related to contemporary global warming. Jason Moore (2015), for example, has suggested an alternative “Capitalocene” to highlight relations of power in the production of social and environmental conditions over the last five centuries that underlie contemporary carbon dioxide emissions under capitalism. The “Plantationocene” has also been proposed to stress the “transformation of diverse kinds of human-tended farms, pastures, and forests into extractive and enclosed plantations, relying on slave labor and other forms of exploited, alienated, and usually spatially transported labor” that might also critically frame the current connections between human history and global warming (see discussion in Haraway 2015).

Critiques of the Anthropocene that call attention to how the designation silences underlying social relationships and inequalities could also be applied to many treatments of “anthropogenic” environments that fail to differentiate social actors (Sayre 2012), including those of archaeologists, historians, and ecologists who argue for a pre-Industrial origin of the period as well as Earth system scientists who view humanity as a homogeneous geophysical force following industrialization. To reiterate an earlier example, cattle pastoralism and irrigated rice agriculture associated with mid- to late Holocene land use in South India had well-attested political effects (e.g., Bauer 2015a2015b; Bauer and Morrison 2008; Morrison 19952009). In short, prehistoric environmental transformations within Asia that altered atmospheric conditions (e.g., Ellis and Wang 1997; Fuller et al. 2011; Huang 1990; Ruddiman et al. 20152016) were tightly linked to the production of social relationships and institutionalized forms of inequality and in that sense were similar to those of contemporary capitalism.

These archaeological and historical cases demonstrate the need to comprehend the politics and social processes of environmental production in the past as well as the present if we are to understand the development of global warming and other changes in the Earth system that articulate with social conditions (see also Ribot [2014] on the “sociocene”). For instance, many large irrigation reservoirs that were constructed in southern India within highly politicized contexts during the period of Vijayanagara imperial rule (ca. 1330–1565) continue to hold water, irrigate crops, and contribute to atmospheric methane today (cf. Bauer and Morrison 2008; Morrison 19952009). These features illustrate the diachronous character of human-related landscapes and their multiple temporalities in contributing to socio-environmental conditions at various scales (see also Bauer and Bhan 2018; Crumley 1994; Morrison 2009). Reframing the Anthropocene as the Capitalocene or the Plantationocene (e.g., Haraway 2015; Moore 2015) places much-needed focus on the social relations of production and consumption that have produced alarming increases in the magnitude of humans’ effects on the Earth system. Both terms also cogently supplant the Anthropocene by focusing on historical sociopolitical processes through which humans have come to dramatically alter Earth, emphasizing social conditions that preceded the invention of the steam engine or the atomic bomb. Even so, we should not forget the fact that humans contributed to geophysical conditions well before the emergence of capitalism.

Land use and its accompanying social relations have long been related to environmental histories and their concurrent contribution to planetary changes. By no means does this minimize the role of capitalist forms of production in understanding the current phenomenon of intensified global warming. Nor does it produce an evolutionary scheme that suggests that an Anthropocene was an “inevitable outcome of human becoming” (Witmore 2014:129; see also Crossland 2014). To the contrary, it is an explicit call to historicize socio-material conditions that have resulted in environmental transformations at multiple scales and to resist progressive evolutionary narratives that imply a distinction in the externality of humans in relation to nature—the “civilized” and the “savage” sensu Morgan (1964 [1878]).

Despite the explicit emphasis that many Anthropocene advocates place on disrupting the concept and ideology of nature, many Anthropocene narratives silently reproduce it by distinguishing a recent time when the Earth system was external to or unaffected by humans from a more recent period in which it is not. In our view, a critical role of archaeology and other historically oriented disciplines is not to push back the start of the Anthropocene; rather, it is to call attention to the historicity of nature, so that we might more fully expose and discuss assumptions about what socio-environmental conditions are desirable, for whom, and how those might be achieved or disturbed. Calling attention to this history unsettles a teleological sense of “the species” as a singular geophysical “force.” It also suggests reconsideration of “business as usual” environmentalist approaches that historically have been structured by the nature-society divide (e.g., Latour 2004) and that, ironically, maintain the ideological basis for global warming deniers to frame climate change as a strictly “natural” process rather than a social-environmental one. To be clear, profound and pervasive planetary changes cannot be attributed equally to the entirety of the anthropos, and it is essential that social relationships and material conditions be investigated among the different institutions, cultural practices, and material processes that produce them; yet, the development of capitalism cannot be the entirety of our account, even as we agree that it is critical to call attention to its importance in underlying alarming and ongoing environmental transformations (see also Bauer and Bhan 2018).

Conclusion

To reinforce the notion of a historical binary, of an “Anthropocene divide,” by precisely dividing the history of Earth into a time in which human social engagement with the production of environments is globally consequential from a time in which it is not flows strongly against contemporary understandings of both human-environment relations and the coupling of human activities with Earth systems from prehistory to present. It is time to put aside concerns for locating an Anthropocene divide. It is our concern that the Anthropocene narratives produced by the stratigraphic formalization of a new geological epoch will form a barrier to developing recognition of the history and diversity of social and environmental entanglements, as well as their contribution to the (re)production of undesirable conditions as the effects of global warming are differentially experienced. If the Anthropocene divide is to be dissolved, as we argue it should be, anthropology must provide theory, critique, and empirical accounts of the historical entanglements of social relationships, cultural practices, and material conditions that recursively shape socio-environmental outcomes embedded within the Earth system. To accomplish this, anthropology cannot walk alone but must work to teach, guide, and collaborate with other scholarly disciplines concerned with humanity and its role in shaping Earth’s past, present, and future.Acknowledgments

Although I generally agree with Bauer and Ellis and their supposition that the designation of an Anthropocene epoch obscures rather than clarifies our understanding of social-environmental change, I believe that the fundamental importance of recognizing an age of humans is lost in their argument. I am in favor of debate about the Anthropocene, as it produces dialogue across disciplines and with the public about how humans have helped create the global environmental crisis and why we need to do something about it.

Bauer and Ellis mirror the position of the Anthropocene Working Group (AWG) that the “anthropocene” and the “Anthropocene” (lowercase vs. uppercase) are very different concepts (Zalasiewicz et al. 2017:219). The AWG is concerned with the uppercase Anthropocene as potentially a formally designated unit of the Geological Time Scale. Their Anthropocene is a chronostratigraphic unit that must have a fixed point in time (with some error bar range, as is common with other chronostratigraphic boundaries), tied to hard rock stratigraphy or a golden spike. General discussions and debates centered on other “anthropocenes” (according to the AWG) are viewed through the disciplinary lenses of their authors (Zalasiewicz et al. 2017:219). These place different emphases on the motives, material evidence, human activities, Earth system processes, and so on, and the AWG argues that they are separate concepts. The anthropocene in regard to Earth system science (ESS), the identification of anthropogenic strata, historical events that propelled changes in Earth system functions, and environmental processes are, according to Bauer and Ellis, “the only Anthropocene designation that speaks directly to the concerns of humanities and social science scholars.” This position is presumably why Ellis can advocate for an Anthropocene focused on the social, political, and historical contingencies of human-environmental ecodynamics and argue that we should “put aside concerns for locating an Anthropocene divide” while at the same time coauthoring several high-impact manuscripts with AWG members supporting a recent Anthropocene boundary marker (e.g., Waters et al. 2016a; Zalasiewicz et al. 20152017). Bauer and Ellis argue that we need to put aside concerns for locating an Anthropocene boundary marker and propose that archaeologists and other social scientists should adopt the Capitalocene or the Plantationocene, focusing on the “historicity of nature.”

The mountain of Anthropocene publications over the last several years, in my opinion, has been both positive and negative. It has fostered conversations across academic disciplines about how different scientists think about natural versus anthropogenic, human-environmental ecodynamics, and the future of our planet. It has sparked interest and high-profile articles in numerous media outlets. The Anthropocene has become a powerful environmental education tool at a time when climate change and climate science are highly politicized, especially in the United States. The Anthropocene encompasses not only anthropogenic climate change but also exploding human populations, pollution, accumulations of plastics in our oceans, accelerating extinction rates, and much more, and perhaps offers talking points that may permeate the defenses of climate change deniers. Unfortunately, conversations about the Anthropocene in the scientific community seem to be turning to academic siloing, following arguments similar to those presented by Bauer and Ellis that the different Anthropocenes should be carved up and controlled by specific disciplines or that we need different terminology to describe, at the broadest level, the same problem—humanity’s impact on Earth (Zalasiewicz et al. 2017). What is lost is Crutzen’s underlying message (in my opinion the only one that really matters) in proposing an Anthropocene nearly 20 years ago, drawing attention to the accelerating modern environmental crisis and guiding “society toward environmentally sustainable management” (Crutzen 2002:23; Crutzen and Stoermer 2000). The Anthropocene, for the public at least, has become a rallying cry to raise awareness about the growing human footprint on Earth. We risk losing this as we quibble over boundary markers, anthropocenes, and the usefulness of the Anthropocene versus the Capitalocene or the Plantationocene. Must we fiddle while Rome burns?

As a historical scientist, I, for one, am comfortable with ambiguity. I realize that I will never be able to completely reconstruct the incredible complexity of the ancient human experience from the shell middens I excavate and analyze. It is past time that the larger scientific community becomes comfortable with, or at least accepts, some level of similar ambiguity with the Anthropocene. I agree with Bauer and Ellis that ESS and the historical processes that helped create the Anthropocene are of fundamental importance, but so is its adoption in our scientific lexicon and our communication with the public. Why replace the Anthropocene with another term or terms and lose all the momentum built toward educating the public and stimulating interdisciplinary dialogues? As I have proposed previously, a merged Holocene/Anthropocene epoch would force us to think about the long-term impacts of humans, which have been variable across time and space, and offer a clear message to scientists and the public about humanity’s role in our growing environmental crisis (Braje 2016). A Holocene/Anthropocene would offer no starting point for humanity’s significant influence on Earth systems but would recognize the long-term, variable processes at work. This turns the conversation from the effects to the causes of the Anthropocene, calls attention to the “historicity of nature,” and concentrates attention on the conceptual merits of the Anthropocene. The Holocene/Anthropocene would function similarly to other previously designated geological epochs (Zalasiewicz et al. 2011:837), as a way to frame interdisciplinary, scientific inquiry of coupled human-natural systems in a practical and meaningful way (Smith and Zeder 2013:12).

“The Anthropocene Divide” by A. M. Bauer and E. C. Ellis provides very cogent reasons for not formally defining a beginning to an “Anthropocene epoch” yet fails in its explanation of the formal basis for a new interval in the Geologic Time Scale. As with most presentations on the Anthropocene, it ignores the true nature, purpose, and history of the chronostratigraphic units (system, series, stage) approved by the International Commission on Stratigraphy (ICS) and ratified by the International Union of Geological Sciences, which serve as the material basis for the geochronologic units (period, epoch, age) of the Geologic Time Scale. The primary argument of “The Anthropocene Divide” is that the human impact on the Earth system has spread episodically over the Earth through space and time and that to demark the now global impact with the term Anthropocene ignores a long history of intensification and dispersal of human impact. The primary purpose was not to describe the nature of chronostratigraphic units. Nevertheless, the authors do, and they do so in a manner promoted in the publications of members of the Anthropocene Working Group of the ICS Subcommission on Quaternary Stratigraphy, for example, that of Zalasiewicz et al. (2015). Finney and Edwards (20162017) challenged the misrepresentation that only a lower stratigraphic boundary must be proposed, approved, and ratified for the Anthropocene epoch to be formally recognized. Yet, what ICS establishes are chronostratigraphic units, which are intervals of stratified rock. A boundary between successive units is materially defined as a stratigraphic horizon in a single stratigraphic section, what is called a Global Stratotype Section and Point. It serves as the global reference on which the boundary is correlated to other stratigraphic sections worldwide. But the key concept is that the boundary is used only to set stratigraphic limits to the chronostratigraphic unit. ICS, the commission on stratigraphy, defines stratigraphic units, specifically, global chronostratigraphic units that are the material basis for the units of the Geologic Time Scale. Numerous recent publications propose stratigraphic markers for the beginning of the Anthropocene, but none provides documentation of the proposed units itself, which would be the Anthropocene series. Waters et al. (2016b) do illustrate the Anthropocene in a lake core, but it consists of only 2 cm of unconsolidated organic matter. It is unfortunate that Bauer and Ellis chose to ignore the nature of the units approved by ICS and instead continue with the serious misrepresentation. Bauer and Ellis cite Waters et al. (2016a) and Zalasiewicz et al. (2015) as providing evidence that “humans’ global physical environmental impacts produce an unambiguous and permanent signature in Earth’s lithological and sedimentary records.” They seem to not realize that stratigraphic documentation, from stratigraphic logs with sample levels and analysis, is not presented in those publications whatsoever, except for the 2 cm of unconsolidated organic matter in a lake core.

Also most pertinent to any discussion of formalization of an Anthropocene epoch is consideration of the usefulness of the term, particularly its stratigraphic application. Since the beginning of recorded human history, many geologic events are recorded in and referred to by years in the Gregorian calendar, and timing and history of all human impact is expressed with the Gregorian calendar. This applies to the lava flows in Hawaii, where individual flows are referred to specific dates (Poland et al. 2016). In geology textbooks, notable volcanic eruptions and earthquakes are listed in tables by the year in which they occurred. The lahar that devastated Armero, Colombia, deposited a thick, extensive blanket of sediment filled with human debris. It is referred to as the Lahar of November 13, 1987. It overlies another extensive lahar deposit that is referred to as the 1845 Lahar. Referring to the Anthropocene and Holocene lahars would be of no value. Throughout southern Europe, human artifacts discovered in soils and on the surface are referred to as Roman. Referring to them as Holocene would be of no value. It is of concern that many who publish on the Anthropocene as a new unit of the Geologic Time Scale fail to understand the basis of the units of the Geologic Time Scale. It is of further concern that they do not realize that the human calendar has replaced the Geologic Time Scale when giving the ages of geologic events and human events (impact) that have long been recorded by humans as they occurred.

Although Bauer and Ellis state that the Anthropocene “designation has been taken up vociferously across the academy,” they fail to recognize that it has not been so within the geoscience and stratigraphic communities. Presentations on the Anthropocene are rare at national and international geoscience meetings, other than by repeated presentations by a few members of the Anthropocene Working Group.

Bauer and Ellis state that “the claim that humans are altering the functioning of Earth as a whole has now been confirmed,” yet they ignore the fact that major changes to the Earth system have been controlled by internal tectonic and magmatic processes and extraterrestrial processes over which humans have no impact and no control and that, in turn, can catastrophically change the Earth system.

Unfortunately with discussions of the Anthropocene, those who are not geological scientists and particularly those who are not stratigraphers too often misrepresent the nature of the Geologic Time Scale, appear ignorant on the nature of stratigraphy, and do not fully understand the Earth system. Further, they seem not to recognize that today we use the human time scale, not the Geologic Time Scale, when dealing with human impact on the Earth system as well as expressing the age and timing of geologic events. Thus, there is no geological/stratigraphic need for an Anthropocene series. And if not formalized as a unit of the Geologic Time Scale, “Anthropocene” can have whatever meaning one wants it to have.

The Importance of Reference Frame

The Anthropocene was not originally introduced as a stratigraphic concept (Crutzen and Stoermer 2000) but rather as a philosophical idea meant to highlight the magnitude of human action in the Earth system. Recently, a group of scientists led by stratigraphers has been considering whether or not it would be valuable to formalize a stratigraphic definition of the Anthropocene, and if so, when and how to define its formal beginning—this is a requirement of all geologic epochs. Such an uppercase “A” Anthropocene would be recognized only after a process of definition, consultation, and ratification of a body largely comprised of Earth scientists.

As colleagues and I argued earlier (Ruddiman et al. 2015) however, the uppercase Anthropocene is an unnecessary concept. The Geologic Time Scale was a triumph of nineteenth-century scientific endeavor but has been rendered largely obsolete by the advent of radiometric dating. Radiocarbon and other techniques allow us to precisely estimate when certain events took place and can in large part trace the diachronous evolution of human-environment interactions around the world since our emergence as a species. We argued then, and continue to argue, for a lowercase “a” anthropocene, a recognition that we live on a planet largely transformed by the actions of our species, even to the point where our actions have become as important as changes in the Earth’s orbit around the sun or plate tectonics in influencing the state of the Earth system. We are also well aware of the problem of a stratigraphic definition of the age of humans, precisely for the reasons cited in this paper: human influence on the Earth system is a process with a long and variable history that emerged with the dispersal and migrations of humans across the planet, had different expressions in different places and times, and was by no means a unidirectional process but rather one that is marked by accelerations, decelerations, and even reversals in the sign of human influences over time on landscapes, plants, animals, and even the chemical composition of the atmosphere.

Given this long and diverse history of the anthropocene, one of the major issues currently limiting our understanding of the processes is the lack of reference frame. The “great acceleration” of anthropogenic activity (Steffen et al. 2011) clearly distinguishes the late twentieth century from earlier periods in Earth and human history, but the period immediately prior to this era or even a few centuries beforehand was also indisputably distinct from the “world without us.” Identifying a world without us surely requires examining the period before the beginning of the Holocene, but as we look into the past Ice Age, the Earth system in its glacial state was so different from the contemporary era that it is extremely difficult to use, say, 50,000 BP as a point of comparison. The global, rapid, and massive climate and environmental changes that occurred during the Pleistocene-Holocene transition are one of the reasons why it is very difficult to disentangle anthropogenic from other factors in explaining the extinction of the Pleistocene megafauna. To identify a period with climate analogous to that of the last several millennia but without substantial human influence, we would need to consider the last interglacial era, around about 125,000 BP, although even at this time anatomically modern humans were present throughout Africa. Perhaps the penultimate interglacial, 200,000 years ago at the dawn of human evolution, would be an appropriate time to consider the “natural” state of the Earth system. Unfortunately, extremely few terrestrial paleoenvironmental archives such as lake sediments—it is on land where we expect to see human influence—have records that extend so far back in time. We are therefore faced with the problem of lack of direct evidence for the evolution of human influence on the Earth system over time.

By the end of the glacial period, at the beginning of the Holocene 11,700 years ago (Walker et al. 2009), humans had spread to occupy even the extremes of all of the continents except Antarctica. On the other hand, many oceanic islands, large and small, were occupied by people only later in the Holocene. While imperfect in many ways, we may use reconstructions and observations of human influence on islands as an analogy for what may have happened on the continents earlier in Earth history (e.g., Boivin et al. 2016; Rolett 2008). Another way to understand how, when, and where humans influenced the Earth system is to employ process models of coupled human-environment interactions; in a hypothesis testing mode, it is possible to contrast model simulations of “the world we had” with the “world without us” (e.g., Kaplan et al. 2016). While it might ultimately be difficult to unequivocally prove that human agency was the cause of changes to landscapes, flora, and fauna, modeling experiments illustrate what could have happened and provide a valuable impetus for further, targeted paleoenvironmental and archaeological investigations.

As Bauer and Ellis point out in this article, the social sciences and humanities are largely concerned with the process (Earth system science) definition of the anthropocene. Many Earth system scientists themselves, however, continue to perpetuate the myth of a planet largely free of human influence in the latest preindustrial Holocene, and this perspective has had a large influence on the discussion surrounding a formal stratigraphic definition of the anthropocene. On the other hand, it is obvious to many archaeologists and historians that the state of the Earth system one or two centuries ago was clearly modified through anthropogenic activities. There is, therefore, an urgent need for social scientists to be engaged in the discussion around the anthropocene and to bring their evidence more clearly in front of the global change community. For many practitioners, this requires a leap of faith; few archaeologists or historians are comfortable with drawing general conclusions beyond their locality or period of expertise. But their synthetic viewpoint is invaluable and, combined with process modeling, will provide a powerful illustration of the state of the Earth system and improve our ability to put things into perspective, that is, to provide a reference frame for the anthropocene.

Ontologies of Occlusion in the Anthropocene

In this superb article, Bauer and Ellis explain how the “species” framing of “Anthropocene” occludes socially stratified causes and effects of climate change. Thus, it is logical that this framing also hides differentiated responsibilities for both cause and care. However, they later merge nature and culture in a manner that can also erase the very possibility of moral judgment and thus responsibility and response. They argue that “Anthropocene narratives … risk downplaying the many nonhuman materials, things, and organisms that people are entangled with and that also contribute to climate and other global environmental changes through a variety of relationships.” Indeed, climate-oriented explanations of weather-related damages are known to occlude the multiple causes of the vulnerabilities that place people at risk (Ribot 2014). Hazards (climate or otherwise) without vulnerability do not cause damage—they work together. With any given hazard, some people are damaged while others are not; that difference is vulnerability, not climate.

But the authors also evoke a different, Latourian-style occlusion—although their nature-culture discussions belie a more nuanced stance. Like Latour, they emphasize the need to attend to (ostensibly ignored) nonhuman things that shape outcomes, despite the fact that attention to these things is already present in any rigorous analysis of causality. Indeed, who ever said that the material world and material objects do not have effects? Was this ever in question? Thus, this object-oriented “turn” (ironically labeled “new materialism”) occludes the long history of analyses of social and material causes of climate crises. All thorough analysts—from Sen (1981) to Watts (1983) onward—bring in human and nonhuman factors.

Unfortunately, Latour goes further. He calls these nonhuman things “agents”—attributing this most-human quality to them. This introduces another occlusion, an occlusion of the role of agency in responsibility; by equating humans with objects, equating agency to any mere force, and thus flattening the relation between human and nonhuman influence—a flat ontology merging subject and object.

Objects can, of course, contain human agency. But they have no agency. Humans contribute to making the world. They influence it. They shape it. They are shaped by it. That relationship still does not give agency—a uniquely human attribute—to things. Things have force. Forces have effects. Effects have consequences. Consequences can, when humans are involved, have meaning. Human agency, like dead labor, is in things and shapes outcomes. This does not (without distinctly human fetishism) give things agency. Nevertheless, the forces that drive and shape things take on particular meaning when we can trace their origin back to humans. It is not agency of the objects that carry it. It is human agency that articulates through them. It is human agency that establishes blame, liability, and responsibility (see Calabresi 1975; Harte and Honoré 1959).

To attribute responsibility, a major reason that imagining an “Anthropocene” (of socially differentiated cause and effect) is worthwhile, we need to maintain the distinction between object and subject, nature and culture. For effective response (my goal), we need to know three things: (1) the human actions and nonhuman forces damaging the environment we depend on (whether or not we generate that environment or influence its nonhuman forces), (2) how we can reduce effects (regardless of their human or nonhuman origins) that undermine our environment, and (3) where to locate responsibility—what society judges can and should be done and who should do it. This responsibility—like blame or liability—cannot be located in the nonhuman forces. The force-agency distinction matters if response is to follow.

Since “should” shapes human action and thus outcomes, it must be within the scientific study of causality within any social system. Yet Latour (2014) tells us there is no history or theory (his irreducibility principle) nor therefore morality (due to his flat nonhierarchical ontology); this framing will miss those things that depend on “should”—social judgment that creates a hierarchy of value. Latour’s radical empiricism blinds us to all of the acts that did not happen (and are thus not visible) but that society judges as necessary or moral. These must be historicized and theorized to discern. In short, the normative is central to any scientific analysis of the multiple causes of disasters—such as the causes of vulnerabilities that turn climate events into crises (Ribot 2014).

“Shoulds” are necessary for the framing of any research that involves humans and that asks “why” something happened. This is because human (in)action is based on judgment. The inaction is visible only through knowledge of judgment—whereas action is manifest. Within a social world there is no asking why without asking about what is socially expected. Hierarchy (of human values), not flatness, guides action. We cannot know what was “not” done unless we know what could and “should” have been done.

This brings us full circle. “Should” is morality. It is located in the unique human characteristic called agency. It is in the will, predicated on the ability to think (à la Arendt 2003). If we view agency as everywhere, including objects, then everything, and therefore no one, is responsible. Tracing cause to an object’s force is fine. Yet, we must continue the search for agency, which is human, to establish the relations of responsibility and the possibility of response.

The Earth moves but is not moved. The Earth is a force without agency. Along with nonhuman forces, it carries in its movement the forces introduced by the agency of humans. That agency is part of causality. It leads us back to responsibility and basis for action—although responsibility can also come from mere knowledge of potential damages (knowledge, the apple, a good starting point for the Anthropocene?). The agency in the Earth is not of or from the Earth. It is ours, purely ours—no matter how it manifests and whether we can control it. True, “the traces of our action are visible everywhere” (Latour 2014:9). But it remains our agency since it is the antecedent that establishes responsibility for the movement that troubles us. We should be moved. We should consider what we do and how it affects others—the golden rule applies (see Arendt 2003).

Further, our being “subjected” to Earth’s vagaries does not give earth subjectivity (à la Latour 2014:9). The Earth remains object, shaped by our agency, but as much object as a table or chair. Placing it on the same plane with me, a subject, is tantamount to war—it is the objectification of humans. This flat ontological object-subject conflation is a frame of war that enables those of us who are subjects and have subjectivity to be reduced to the nongrievable equivalent of an object (Butler 2009). It is the equivalence, the erasure of difference, that reduces us. It is distinctly unethical. Humans are not equivalents of objects. Being is hierarchical—we live in a round world.

Once we distinguish humans from objects and recognize them as the locus of agency, then responsibility can be attributed and response can begin. I see no utility in asking whether humans are nature, since human nature, the ability to think and judge, is nature and is what distinguishes us from the remainder of the nature of which we are a part.

“A word means what I choose it to mean, no more and no less.” This pronouncement by Humpty Dumpty in Lewis Carroll’s Through the Looking Glass might be recalled in considering Bauer and Ellis’s contention that the “Anthropocene” as a sharply delineated geological term does not serve anthropology well and therefore should be more generally rejected. Their contention and accompanying assertions, though, are widely open to question.

Bauer and Ellis begin by saying that any such sharp delineation (“periodization”) is invalid because the relationship of humans to the Earth reflects a complex continuum (paradoxically, they do not reject the Holocene and Late Pleistocene even though these cut across the same continuum). We emphasize here that scientists working in the framework of geology and Earth system science (ESS) see all Earth history as comprising complex, continuous, and pervasively diachronous change and yet they regard the “periodization” given by formal geological time units as essential to their work. This is because these precise, synchronous, internationally agreed boundaries lead to unambiguous communication and enhance interpretation and understanding. They intermesh effectively with a wide and varied array of other time-related units (litho-, bio-, cyclo-, magnetostratigraphic, etc.) to build a detailed picture of Earth history. Earth system scientists find such “periodization” exceptionally useful because it provides a consistent way to discern and communicate significant changes in the structure and functioning of the Earth system from a very large amount of useful data, including data from archaeology and anthropology.

The Anthropocene concept and term indeed originated with Paul Crutzen (Crutzen 2002; Crutzen and Stoermer 2000) explicitly as a geological epoch/series to succeed the Holocene and was soon widely adopted by the ESS community. As interest in this concept grew, the term was also noticed by stratigraphers, with initial evaluation suggesting that it “had merit” as a potential formal geological time unit and should be investigated further, an extensive technical process initiated in 2009 by the Anthropocene Working Group (AWG) of the Subcommission on Quaternary Stratigraphy, part of the International Commission on Stratigraphy (ICS). In this context, the Anthropocene is being examined as a potential unit in the parallel chronostratigraphic/geochronologic “dual hierarchy” (i.e., as both a potential series and epoch) of the International Geological Time Scale.

This “dual” timescale is specific to geology but is just one of many means by which humans measure or subdivide time and is distinctive in simultaneously comprising synchronously bounded material units of strata (e.g., series) and their equivalent “pure” time units (e.g., epochs; Zalasiewicz et al. 2013). It is used to subdivide Earth history (not human history), which continues to the present and in recent times encompasses both human- and nonhuman-formed phenomena. We know of no equivalent timescale in anthropology, archaeology, history, or other cognate disciplines. It may of course be used in these or other disciplines when considered appropriate (see, e.g., Vidas, Zalasiewicz, and Williams 2016 regarding its relevance for international law), as with Bauer and Ellis’s use of Late Pleistocene and Holocene.

Key to the geological viability of the term is the distinctiveness of the stratal record, not least because this is the only means by which recent events can be related to the whole of Earth history. This record shows Holocene relative stability persisting even as substantial human civilizations rose and fell, leaving rich archaeological traces of their interaction with the environment. Plausibly, anthropogenic activities might have drip-fed greenhouse gases into the atmosphere for millennia to maintain CO2 levels and therefore Holocene climate stability (Ganopolski, Winkelmann, and Schellnhuber 2016; Ruddiman 2013). “Anthropogenic,” though, is not synonymous with “Anthropocene,” for which the key distinction is decisive and essentially synchronous impact at a geological scale.

Diverse stratigraphic markers indicate that strata from the mid-twentieth century onward can be clearly and widely distinguished from earlier strata (Waters et al. 2016a). These indicators belie Bauer and Ellis’s complaints (i) that the archaeological record has been ignored in the process, as they are commonly archaeological in nature (e.g., plastics, concrete, persistent organic pollutants, fly ash, artificial radionuclides), and (ii) that the currently suggested start of the Anthropocene represents “an arbitrary break.” The accompanying perturbation to sedimentation has been large and global, producing pervasive stratigraphic records. For instance, humans have placed large dams on the main stems of ∼2,500 rivers globally in less than a century, reducing sediment delivery to the coast such that coastal successions on every continent except Antarctica now record this near-synchronous event. Overall, since 1950, humans have been moving more sediment annually than wind, glaciers, and rivers combined. Earlier records of humans engaged in terracing, emplacing small check dams, or deforesting areas of Europe represent an important, indeed fundamental precursor to this phenomenon, but one that was patchy, diachronous over several millennia, and largely confined to land. These early records, for all their historical importance, cannot satisfactorily define a global and synchronous (chronostratigraphic) boundary that is geologically effective.

The stratigraphic record is congruent with the recognition of a major, ongoing perturbation of the Earth system (Steffen et al. 2016; Zalasiewicz, Waters, and Head 2017), including unprecedented change to the carbon, phosphorus, and nitrogen cycles and the biosphere, both marine and terrestrial. Energy consumption by humans since 1950 exceeds, by some 1.6 times, that of all of human history before 1950. One metric, the Anthropocene factor (Gaffney and Steffen 2017), over the last 65 years is orders of magnitude larger than for the entire Holocene interval prior to 1950. Such force multipliers show that humans have geologically very recently acquired the energy levels, the population, and the resource (engineering) application to significantly and globally change the Earth system: abundant evidence of this transformation now exists in the stratigraphic record (Waters et al. 2016a; see fig. 1).

Whether ultimately formalized or not, this is a major change in our planet’s history, considerably sharper than most other boundary intervals of the Geological Time Scale and capable of being precisely defined stratigraphically. It is a phenomenon also sharply distinct from the first evidence of, or early trends in, anthropogenic traces on land. It would be obfuscatory to conceal this change under the cover of “a complex continuum.”

This stratigraphic record represents a precise, clear, and valid definition of “Anthropocene”—but it is not an exclusive one, and it may not be relevant to all fields of human-dimension scholarship. The interpretation of the Anthropocene as presented by Bauer and Ellis bears scant relation to the one we have described above. Rather, it resembles the Anthropocene proposal of Ellis et al. (2016; although they do not mention this proposal nor responses to it [e.g., Zalasiewicz, Waters, and Head 2017]); this former proposal by Ellis et al. was similarly nonviable as a Geological Time Scale unit and similarly obscured the post-mid-twentieth-century changes. Ellis et al. (2016) had argued that the Anthropocene should not be rejected but rather removed from the ICS mandate and recast in social science terms.

In the English language, many words bear multiple, distinct meanings (“nature,” for instance). Naturally, this risks confusion, but nevertheless we would not presume to “supplant” other interpretations of the Anthropocene. The remit of the AWG is understandably to frame the Anthropocene in a geological context.

If such terms as Capitalocene and Plantationocene are thought useful by social-science communities to describe human influence on Earth, then perhaps this will resolve the “many Anthropocenes” in current use. These terms do not, however, “supplant” the “geological” Anthropocene, as they represent different concepts, from different contextual backgrounds, with social science interest on the socioeconomic drivers of change rather than on resultant Earth system behavior and its petrified and strata-bound consequences. Social science investigations are not irrelevant to understanding Anthropocene stratigraphic and Earth system change; to the contrary, the dynamics of human/technology interactions are clearly crucial to this question. Similarly, the Ordovician-Silurian boundary may be satisfactorily and pragmatically defined in strata even as the Earth system dynamics that drove this period-scale change remain unresolved, intensely debated—and hugely important.

The main thrust of Bauer and Ellis’s paper is captured by their claim that the stratigraphic and ESS definitions of the Anthropocene are based on “distinguishing a recent time when the Earth system was external to or unaffected by humans from a more recent period in which it is not.” This is obviously not true. The ESS definition is based on the evidence that the planet is on a strong trajectory out of the Holocene (and indeed out of the glacial-interglacial cycling of the late Quaternary) and that human activities are the primary driver of this trajectory (Steffen et al. 2016). This does not imply that there was inconsequential human influence on the Earth system before the Anthropocene. Of course there was, as the Bauer and Ellis paper shows in some detail. However, it was only since the mid-twentieth century that Earth system scientists can say with some confidence that a trajectory out of the Holocene clearly began. For them, placing a Holocene-Anthropocene boundary there seems natural and incontrovertible given the evidence. This parallels the stratigraphic perspective, where the putative Anthropocene series, although clearly characterized by a range of novel proxy signals (e.g., Waters et al. 2016a), negates Bauer and Ellis’s argument that the Anthropocene somehow represents a black-white divide between no human influence and massive human influence. The Holocene already accommodates the rich evidence of human environmental imprint (Gibbard and Walker 2014).

Bauer and Ellis fail to acknowledge the complex-system nature of our ocean-dominated planet and this importance for the Earth system definition of the Anthropocene. Complex systems have many definitions, but two features are common to all of them: (i) emergent properties at the level of the system as a whole that cannot be aggregated up from subsystems or individual components of the whole system and (ii) attractors or reasonably well-defined states that are characteristic of the system as whole. The Anthropocene is on a rapid trajectory away from the Holocene/interglacial attractor (or more appropriately, away from the glacial-interglacial limit cycle of the late Quaternary) but is not yet an attractor in its own right. Bauer and Ellis detail the rich background to human development and influence on the Earth system but do not acknowledge our planet’s shift as a complex system that began around the mid-twentieth century. The long anthropological story of human development occurred within the Pleistocene glacial-interglacial limit cycle (the Holocene being the latest interglacial) of the Earth system. In short, Bauer and Ellis confuse human influence on the Earth system with a change in state of the Earth system as a whole. This confusion has long surrounded the Anthropocene concept and is not unique to their paper.

We emphasize that all these various approaches are nonexclusive and complementary, and we are puzzled as to why Bauer and Ellis should regard them as some kind of battlefield, with the Anthropocene as a singular trophy to be fought over and won or lost. Anthropologists and archaeologists, who search for and map out the early evidence of human activities and their patterns, offer much to the stratigraphic/ESS study of the Anthropocene (and, we trust, vice versa). Without the evolving dynamics of human-Earth relations over the long term, the Anthropocene as we consider it here would not have happened. We note the genuine, wide-ranging, and generous interdisciplinarity that the Anthropocene has stimulated; this has been among the most positive features of this phenomenon. We dearly hope to see it continue and strengthen but note that interdisciplinarity does not mean an absence of disciplinary coherence.

Missing the Mark: On the Matter of Narrative and Social Difference

We are grateful to the commentators for engaging our essay and contributing to this forum. Their diverse perspectives emphasize the many distinct ways that the Anthropocene is being imported across the academy. Some see its utility as a political label, others stress its utility as a neutral geological period, and still others question its usefulness as either. While there is much agreement among the positions offered and the views we expressed in our essay, there are also significant points of misunderstanding or avoidance of our principal critiques of the Anthropocene periodization that deserve clarification in the interest of fostering productive interdisciplinary discussion.

The commentary of Zalasiewicz and colleagues of the Anthropocene Working Group was ostensibly the most critical of our position. Yet they also miscast our argument, evaded the more significant critiques that we foregrounded, and failed to acknowledge that the main Anthropocene narrative to which we and others are responding was in fact generated by Earth system scientists who promote the designation. To be clear, our essay does not challenge whether the Earth system is undergoing a state shift related to recent human activities or whether the magnitude of human impact has significantly increased. Rather, our essay problematizes the way in which geological systematics and the scientific narratives produced by Earth system scientists in accounting for this state shift frame historical processes and how that framing has been taken up by scholars.

Zalasiewicz et al. argue that we confuse “anthropogenic” for the “Anthropocene” (despite our explicit discussion of a tipping point and a recent state shift) and that we fail to recognize Earth as a “complex system.” Here they seemingly misunderstand our usage of the term “assemblage.” Similar to how natural scientists define “complex systems,” social scientists conceptualize assemblages as complexes of heterogeneous elements that, through their historical configurations and dynamic interactions, produce emergent outcomes—in other words, the whole is greater than the sum of its parts (cf. Bennett 2010; DeLanda 2006; Thomas 2015). We are aware that human activities do not simply add up to systemic change (cf. Turner et al. 1990), and we are not denying that geological or historiographic periods have disciplinary utility—indeed, archaeologists make heavy use of periodizations, albeit primarily at regional scales (e.g., South Indian Iron Age). As Finney noted, our essay does not challenge the validity or usefulness of an Anthropocene chronostratigraphic unit to geological systematics, though as both Finney and Kaplan diligently point out, its utility remains far from certain (see also Ruddiman et al. 2015).

The thrust of our argument is that the Anthropocene divide, the separation of a pre-Anthropocene from the Anthropocene, neither represents a shift in human agency from being merely “ecological” to becoming fully “geophysical,” as many have argued (see below), nor helps us to understand the historical, cultural, and political processes through which humans contribute to and transform Earth’s functioning as a system. Zalasiewicz et al. reiterate the geological need for a globally isochronous marker for anthropogenic global change; our point is that such a marker would not capture the socially differentiated and diachronous character of historical human-environmental entanglements that have contributed to a state shift in the Earth system. While one might question the degree to which any periodization could reflect such historical processes—as Kaplan’s commentary lucidly addresses in considering the anachronism of the Geological Time Scale more generally—our concern is explicitly with how the Anthropocene periodization obscures connections between pre-Anthropocene/Anthropocene human-environmental relationships while also foreclosing socially differentiated understandings of human-environmental interactions with its emphasis on the species. Zalasiewicz et al. mistake our interests in the geophysical impacts of human activities in prehistoric periods and the previous call of Ellis et al. (2016) for broadening interdisciplinary discussion with an attempt to win the “Anthropocene as a singular trophy” and sidestep our actual concerns for how human-environmental relationships are understood and narrated, given the critical recognition that narratives, scientific or otherwise, have ideological and political consequences.

When Zalasiewicz et al. sardonically dismiss the variable “meanings” of the Anthropocene to claim that a geological Anthropocene references the period in which the Earth has undergone its most recent state shift and little more with respect to historical processes or different kinds of human agency, they are reinforcing disciplinary divides and blatantly ignoring that many of the Anthropocene’s principal advocates, including Earth system scientists responsible for promoting the term, have explicitly provided narratives of human history to accompany the geological designation. Steffen, Crutzen, and McNeill (2007), for instance, state that the Anthropocene is “the current epoch in which humans … have become a global geophysical force” and that their “objective” is to examine the “evolution of humans and our societies from hunter-gatherers to a global geophysical force” (614). Such historical claims imply that humans did not have (global) geophysical effects prior to the Anthropocene. Thus, as humanities scholars have taken up the Anthropocene as a period when humans transitioned from being ecological actors to being “geological” actors, or the “inception of humanity as a geophysical force” (cf. Chakrabarty 2009; Morton 2013:7), they are not “confusing” the writings of Earth system scientists on the Anthropocene; rather, they are carefully considering the implications for their respective disciplines, such as Chakrabarty’s (2012) lucid recognition of “disjunctive” forms through which historical agency might be understood.

A primary concern of our essay is how the Anthropocene periodization has been taken up in such terms (e.g., geophysical vs. biological) and the ways in which it may, as Kaplan cogently remarks, “perpetuate the myth of a planet largely free of human influence in the latest preindustrial Holocene,” a myth that has heavily influenced “discussion surrounding a formal stratigraphic definition of the anthropocene.” In contrast to the suggestions of others, we stressed that the Anthropocene periodization cannot be taken as the beginning of humans’ “geophysical” impacts, as Zalasiewicz et al. also acknowledged. Moreover, explanations for the recent state shift in the Earth system must address prior intervals, especially if we accept that many human-related landscape transformations of thousands of years ago, such as the creation of methane producing irrigated landscapes and widespread deforestation, continue to affect the functioning of Earth’s biosphere and climate system today.

We welcome calls for complementarity and collaborations with archaeologists. However, interdisciplinary collaborations on relationships between human activities and Earth’s systemic functioning should not only mean sharing data or borrowing models but also learning from the critical perspectives that others bring—and this is especially relevant to narratives of the Anthropocene periodization. As archaeologists and historians know well, historical narratives are powerful in what they affirm and silence, ideologically (re)produce, and constrain and allow in discursive practice. Archaeologists, for instance, have been actively concerned with how their claims risk naturalizing or perpetuating presentist ideological constructs, such as those of nation or individual, or framing some humans as passive objects of history and others as its active makers (e.g., Leone, Potter, and Shackel 1987; Meskell 1998; Trigger 1980). As Earth scientists begin to write human history with archaeologists (or without them), we hope that they will be similarly open to such critical introspection.

In this regard, we disagree with Braje’s comments that our critique of the Anthropocene is tantamount to “fiddl[ing] while Rome burns.” While Braje “generally agree[s]” with our assessment of the Anthropocene’s obscuring tendencies, he nevertheless embraces the Anthropocene for its political work and appears less concerned with its occlusions (aside from arguing that it be extended to all of the Holocene). Although the contemporary politics of climate change were not the primary concerns of our essay, we nonetheless suggested how an uncritical acceptance of the Anthropocene periodization might actually work against a more inclusive environmental politics to mitigate the deleterious environmental effects of human activities. To start with: it potentially naturalizes a recent state shift as a teleological outcome of human evolution; it silences social differences and responsibilities with its emphasis on the species; it risks denying forms of historical agency outside of recent Euro-American innovation; and it effectively reproduces a society versus nature ideology that paradoxically enables “deniers” to maintain the position that climate change is purely “natural.”

We have noted several of these concerns before (e.g., Bauer 2015b; Ellis et al. 2016), and one of us has expanded on the Anthropocene narrative’s complex implications for environmental politics in considerably greater detail through other collaborations and mediums (see Bauer and Bhan 2018 for discussion). Here we will simply stress that to cast our critique as superfluous “quibbling” is to overlook an important point: that a critical framing of the historical process might enable ways of shaping both social relationships and environmental outcomes other than what is made possible by an emphasis on the emergence of the species as a singular “geophysical force” that recently came to “dominate” those of nature. This is why we have stressed the need for a political ecology (e.g., Biersack and Greenberg 2006; Robbins 2012) and are sympathetic to calls for a Capitalocene and other sociopolitical orientations, even while acknowledging that a critical history of capitalism cannot be the entirety of our account or the only alternative (see Bauer and Bhan 2018). Braje seems less bothered by the political implications of the silences (sensu Trouillot 1995) in the received Anthropocene narrative. We disagree with him regarding their importance (see also Bonneuil and Fressoz 2017).

Ribot agrees with us that the Anthropocene’s generalizing tendencies, in focusing on “the species,” mask important questions about social differences and responsibilities. Yet he equates our framing of the functioning Earth system as a dynamic assemblage to a “Latourian-style” merging of nature and culture that may erase the possibility for “moral judgment and thus responsibility and response.” Ribot’s concerns that posthumanist approaches that “distribute” agency (sensu Bennett 2010) foreclose important questions of ethics and intentionality dovetail with the positions of many others (cf. Martin 2014; Van Dyke 2015). We share these concerns and stress that our calls for a political ecology and emphasis on inequalities in the production of socio-environmental conditions are hardly a charge for “flattened” agency or responsibility. However, not forgetting the range of materials and other-than-human organisms that also give shape to Earth and through which human actions are entangled and realized is important for recognizing how humans partly shape social and environmental conditions simultaneously. There are many good reasons for rejecting the hubris of Anthropocene narratives that suggest humans now “dominate” nature, as Finney also effectively points out. In response to Ribot’s principled concerns, recognizing the social effects of things or that the production of climate is ontologically distributed does not mean that everything is an equal actor or the same kind of actor or even that the same “thing” will have the same effects in different contexts (e.g., Bauer and Kosiba 2016; Kipnis 2015). Hence, it does not exclude important questions of ethics, intentionality, or responsibility in regard to climate change; rather, it calls them to the fore in political discussion (see Bauer and Bhan 2018).

As these commentaries exemplify, there are many reasons why interdisciplinary discussions on the concept and utility of the Anthropocene should continue. As most of us agree, there is need to understand the historical entanglements of social conditions, materials, nonhuman life, and Earth system functioning. Moreover, there is still much to clarify as scholars are progressively drawn into conversations that go beyond the comfortable confines of their home disciplines, given that human-related climate change and mass extinctions are increasingly recognized as some of the greatest political concerns of our time. We the authors (Bauer and Ellis) have different disciplinary training and research objectives and are not in full agreement about the usefulness of the Anthropocene (or an anthropocene) designation to our respective fields or social concerns. However, that has not stopped us from finding common ground and learning from the critical perspectives that we can offer each other.

Narratives matter. “That which is said to have happened” recursively affects that which happens (Trouillot 1995:2). And this is just as true for narratives written by anthropologists, archaeologists, ecologists, and historians as it is for those written by geologists and Earth system scientists.

Anthropocene anthropology: reconceptualizing contemporary global change

Amelia Moore

Abstract

The Anthropocene is the scientific label given by earth scientists to the current epoch of unprecedented anthropogenic planetary change. The Anthropocene is also a political label designed to call attention to this change and evolving notions of agency and responsibility in contemporary life. This article critically explores what I call ‘the Anthropocene idea’ and the condition of ‘Anthropocene spaces’ through selected anthropological writing about recent planetary change and through analysis of current events in a specific ‘vulnerable’ location. By considering recent events in The Bahamas, I arrive at an orientation that I call simply Anthropocene anthropology. Rather than advocating for the creation of a new subfield of research, this mode of engagement offers an open-ended conceptual framework for the critical examination of the Anthropocene idea as it influences the symbolic and material realities of contemporary Anthropocene spaces.

This article is a critical exploration of a concept that is poised to breach the walls of academia and become an international buzzword: the Anthropocene. The term has been proposed as a designation for a new planetary epoch, encompassing the present and recent past, in which human processes drive all major earth systems. The Anthropocene idea has spread from the domain of the earth sciences into the realm of the social sciences, sparking conversations about the stakes and form of humanistic research. This article can be read as one possible approach to the anthropological engagement of the Anthropocene idea. I call this approach Anthropocene anthropology.

My goal in presenting this article is to orientate analysis around the Anthropocene as a concept that reflects the recent creation of a contemporary problem space.1 Ideas about global environmental change influence thought and action in a number of arenas, and I hope to see anthropologists tackle the breadth of this planetary imagination animating emergent cosmologies of anthroposbios, and geo. New frameworks are needed to keep pace with authoritative arguments about collectivity and responsibility in the face of a changing world. These arguments attempt to define the present (and therefore the future and the past) for ever-increasing numbers of people (and nonhuman beings). Such definitions enable new possibilities and processes while foreclosing others. By engaging the discourses and processes enabled by the Anthropocene idea as they help to transform practices of life and work, knowledge produced about place and space, infrastructural aesthetics, and the evolving language available for subjectivation, we also engage the Anthropocene on material and symbolic levels (Beirsack 2006).

The greater argument underpinning this article is that even in an era of rapid change, we still need critical analysis of the characterization of that change and responses to it. I conceptualize my own work as an anthropological awareness ‘of’ the Anthropocene (understanding the idea as a historically contingent manifestation of social, political, and material processes), as opposed to work that is un-reflexively ‘in’ the Anthropocene (taking the framing of the problem and responses to it for granted). We need anthropological analysis that can examine the characterizations of life and change that are being made within authoritative fields of power and that can follow these ideas as they affect institutional policies with real consequences for the everyday lives of the people we work with around the world. We need concepts that can both speak to and evolve with emergent trends. At the risk of being chastised for not acknowledging the stakes of anthropogenic change, I want to make sure that we continue to maintain a space for the untimely questioning of the present (Rabinow 2008) in a time when ‘the obvious’ is solidifying rapidly around us (Raffles 2002). This orientation is a necessary complement to all the work we anthropologists do as partners in the fight against unjust and deadly global change. The work I advocate here is a part of that fight.

This article is divided into five further sections. First, I provide a brief ethnographic introduction to one location with renewed relevance in light of the Anthropocene idea: the islands of The Bahamas. Second, I explain the Anthropocene in more depth, introducing the significance of the idea for both the sciences and humanities. Third, I explore different anthropological engagements with global environmental change, providing a brief discussion of select existing work. Fourth, I introduce a platform for an Anthropocene anthropology that might be applicable in ‘Anthropocene spaces’ like The Bahamas. I conclude with an appeal for continued open-ended analysis of contemporary life in any locale said to be marked by anthropogenic planetary change.2

While this piece is not an in-depth ethnographic exploration of The Bahamas, I have written about contemporary life in these islands elsewhere (Moore 2010a2010b20122015). In the following section, I use brief examples of current events in that location to introduce some of the ways in which experiences of and ideas about global change have come to influence the narratives, relations, and spatializations of human and nonhuman life. These Bahamian examples ground the following sections on current anthropological engagements with global change and the Anthropocene.

The Bahamas and global change

The Bahamas consists of over 700 islands and cays – an archipelago – in the western Atlantic stretching between eastern Cuba and southern Florida. The nation is a designated small island state under the Barbados Program of Action with a small, majority Afro-Caribbean population of approximately 320,000 and an economic dependency on the international tourism industry and foreign investment. The Bahamas is also increasingly described as home to the third largest reef system in the world, a large marine carbon sink, a number of endemic species, and several distinct island ecologies (The Islands of The Bahamas 2013a2013b; Westphal, Riegl & Eberli 2010). The nation has been internationally defined by its marine relations, from sponge trading and boat building in British colonial times to coastal development and beach vacationing today. Once known as the ‘isles of June’, the archipelago is now often characterized as the ‘ephemeral islands’ in an era of planetary crisis (Bell 1934; Campbell 1978).

I have travelled to The Bahamas for over a decade, exploring what it means to visit, study, and live in the ephemeral islands. The tourist industry of The Bahamas has been extremely successful in selling a brand of ‘tropicalized’ island ecology, from lush vegetation and palm-fringed beaches to azure waters and vibrant marinescapes (Thompson 2006), but the actual experience of these island ecologies is something else entirely. Spindly pine forests in the northern islands give way to dense coppice woodlands in the central islands and then to arid bush, bent by the winds, in the southern islands. The bedrock of the Bahama Banks is composed of porous limestone, an accretion of calcareous sediment deposited over millennia, and rain water (the only ‘natural’ source of fresh water) collects in fragile aquifers beneath the ground. Beaches range from white, powdery sand that swallows footprints to sand that takes on a delicate pink blush resulting from the build-up of tiny invertebrate shells. Other shores are rough and craggy, cutting like knives into bare feet.

I have learned from fishermen and ecologists that in the dense mangrove marls one is likely to come upon well-used middens (mounds of conch shells discarded by nearby fishers that are generations old at the bottom and freshly killed at the top) while navigating channels in a small boat. I have observed the way that buildings weather on the islands, responding to the sea air, heavy rains, and smoldering sun, revealing layers of pastel paint or the texture of brain coral mixed into the stuff of the building stones. I have stopped being surprised when stairways leading down sand dunes to the beach abruptly end in mid-air as the sands recede into the ocean after seasons of wave action and rising tides. And in Nassau, I fall asleep too often to the acrid smell of the perpetually burning city landfill mingled with the scent of local thyme left over from dinner.

What strikes me is that the islands are intensely alive, animated by anthropogenic and biogeochemical processes both in and out of the water, and this life is a central part of the social worlds of The Bahamas. The examples are never-ending: human waste and run-off lead to algal blooms offshore that affect the course of coral growth, inspiring novel restoration plans; hot pink shards of conch shell adorn roundabouts that direct traffic around the latest mega-resort; underwater, whip-like crawfish antennae wave from under artificial habitats laid by fishers; clouds of flying termites migrate through window screens during heavy downpours; tiny anole lizards hunt for insects in the dark corners of the house.

Bahamian ecologies shape and are shaped by those who live and work in The Bahamas and by multiple forms of anthropogenic change. These shifting ecologies are a large part of the materiality of Bahamian living, participating in the postcolonial contingencies of everyday life. I have experienced how the question of anthropogenic change affects the lives of Bahamians as well as the activities of regional environmental management communities along with national conversations around tourism and development. Multiple problems linked to the Anthropocene idea in The Bahamas include physical vulnerability to climate change, marine biodiversity loss, coastal erosion, fossil fuel dependency, and coral reef disappearance. These ‘Anthropocene problems’ are viscerally experienced by Bahamian island residents and increasingly called upon by the natural sciences and other industries to justify the speculative reorientation of local and regional geopolitics, interspecies relations, land- and marinescapes, field research, and travel markets.

In terms of geopolitical positioning, postcolonial arguments about regional distinction (in which The Bahamas is positioned by members of its government as unique in the Caribbean in terms of per capita wealth and sophistication in the tourism industry [Cleare 2007]) now sit side by side with arguments about impending anthropogenic disaster. The Bahamas, as a low-lying archipelagic nation, is imbricated in multi-scaled global change predictions that influence the creation of alliances centred on the small island (such as the Alliance of Small Island States [AOSIS] at the United Nations, of which The Bahamas is a member), and the small island is now institutionally defined by social, economic, and environmental fragility in the face of anthropogenic planetary change.3 Sea-level rise as a result of global warming is predicted to be a grave national threat within the very near future (Hamilton 2003; London 2004), sparking one Bahamian speaker at a recent conference at the national college to state, with a strong sense of irony, that ‘many of us will be environmental refugees’ who have to ‘head to the hills of Haiti’, and to ask: ‘Forty years after independence, will we have another forty years going forward?’4 These predictions are also debated privately after storms remove sections of coastline, flooding homes and roadways (a palpable inconvenience in terms of connectivity and cost), leading to conversational speculation over pub beers in Nassau about the sensibility of investing in coastal property or infrastructure.

Simultaneously, justifications for the country’s fisheries sector, following themes in international marine conservation, have switched from exhortations for growth and expansion to precautionary tales of declining numbers of commercial species and poor reef health as just some of the detrimental impacts of overfishing in recent decades (Buchan 2000; Chaplin 2006; Chiappone, Sluka & Sullivan-Sealey 2000; Clark, Danylchuk & Freeman 2005; Moore 2012). One of the ways this framing has manifested in The Bahamas has been through government partnership with local and international environmental NGOs to obtain Marine Stewardship Council (MSC) certification for the harvest of Spiny Lobster, the country’s main fisheries export. Fishers are worried that without product greening via international MSC certification, important lobster markets in the European Union and United States will soon be closed to Bahamian exports as consumers demand a sustainable stamp for their imported seafood (Smith 2011; World Wildlife Fund 2013). One Bahamian woman with a family history of fishing in the island of Eleuthera explained to me that lobster used to be so abundant that their bodies were used as pineapple fertilizer, but the value of these species drastically changed over time as the Bahamian pineapple market dried up and lobster became a global luxury food item, making lobster a million-dollar fishery. MSC certification was now necessary she said, ‘so we can continue to sell to Walmart’, registering the irony that the promotion of sustainable fisheries is increasingly central to international commodity chains linking large-scale commercial fishing and the mass consumption of marine products.

Similarly, the recognition of anthropogenic biodiversity loss has led to re-imaginations of space in the archipelago. The number of existing and proposed marine protected areas (MPAs) in The Bahamas dramatically increased in the last decade owing to the country’s commitment to international conservation plans. For example, The Bahamas has committed to the Nature Conservancy’s Caribbean Challenge Initiative (CCI) to enclose 20 per cent of its marine and coastal space within protected areas by 2020. The CCI justifies its regional plans with the argument that ‘the Caribbean contains some of the world’s richest marine biodiversity … 10% of the world’s coral reefs, 1,400 species of fish and marine mammals and mile after mile of mangrove forests … Alarmingly, the Caribbean is increasingly threatened by development, pollution, overfishing and climate change’ (The Nature Conservancy 2013). However, these NGO arguments are complicated by some Bahamian fishers, in the Berry Islands, for example, who fear that there will soon be more restricted space than open space for local fishing, ‘more red dots on the map’, and that MPA restrictions exacerbate ongoing transitions of land and reef from the generational use of islanders descended from colonial slave populations to real estate leased to foreign development companies (Stoffle 2013).

Finally, it is important to realize that engagement with global change in The Bahamas includes actions within industries and markets outside of conservation. In a 2013 speech given in observation of The Bahamas’ fortieth anniversary of independence, the Prime Minister reminded citizens that ‘tourism is the lifeline to The Bahamas’. Marketing The Bahamas has always been an effort in place-making, and the islands of the country are considered by its Ministry of Tourism to be ‘tourist products’ in competition for global travellers (Cleare 2007; Jefferson & Lickorish 1991; Moore 2015). I have witnessed the rise of the ‘sustainable tourism destination’ as an emergent product appearing alongside the mainstay postcolonial paradise model of tourism (Strachan 2002). In addition to calls for regional ‘carbon neutral destinations’ (Moore 2010b), some developers in The Bahamas are designing, building, and marketing self-sufficient travel destinations using island-based principles to keep resource use to a minimum (Schooner Bay Ventures Limited 2008). The tourist product has long influenced the basic life-ways of the islands in terms of building codes, community social relations, racialized spatialities, and household aesthetics, so it is no surprise that plans for sustainable tourism spill over into local thoughts about daily life. Yet for some younger Bahamians working in the island of Abaco and thinking about starting families, sustainability also means trying to maintain a ‘Bahamian style of community’ – living next to your neighbour in dense settlements and looking out for one another – as opposed to the prevailing model of private, segregated enclave development. For many Bahamians, knowledge about sustainable living in the face of global environmental change will always be linked to travel markets, experienced as debates over life-style and the quotidian details of community life.

These examples represent some of the ways in which the physical spaces and socioecological relations of the country continue to be transnationally framed as fragile, vulnerable, and in need of redesign within the networks of knowledge and governance concerning global change. These are simultaneously some of the ways the experience of global change and its rhetorics come to affect the everyday lives of those who reside in the islands. Bureaucratic discourse is framed around events in the archipelago as exemplary of global concerns, but the results are felt close to home. These examples are neither exhaustive nor unique to The Bahamas. However, they represent the kinds of complex emergent conjunctures that have coalesced around the Anthropocene idea and the experience of The Bahamas as an Anthropocene space.

These examples also raise a number of interrelated questions that require further anthropological engagement as ethnographic problems: How do we characterize this process of political creation that leads to geopolitical alliance, rearticulated subjectivities for island residents, and transformations of the value of landscape and infrastructure? What forms of reason hold projects like MSC and the CCI together, and how is this Anthropocene logic materialized in social relations, relations with other life-forms, and experiences of space and place? How do we understand human life in the context of lively anthropogenic ecologies informed by an awareness of global change? What kinds of stories do experts and laypeople tell in order to locate themselves in global change narratives and enroll others in planning for change? Who designs the mental and material models that inform the experience of life in an Anthropocene space?

In order to begin to approach these questions – perhaps better characterized as an anthropological puzzle for the Anthropocene – I have compiled a select collection of recent work and useful concepts that I think move us closer to an Anthropocene anthropology. However, before I delve into those compilations, I must further explain the Anthropocene idea.

The Anthropocene idea

Despite the fact that there have been a number of international conferences and even a journal dedicated to the subject, the term ‘Anthropocene’ is of very recent origin. The idea was formally introduced to the scientific community in 2000 by the atmospheric chemist Paul Crutzen and the biologist Eugene Stoermer in the back pages of the International Global Change Newsletter (Crutzen & Stoermer 2000), published by the International Geosphere-Biosphere Program (IGBP). Since then it has been popularized by Crutzen and others, who have campaigned for the term to label a new geological epoch encompassing the earth’s present, recent past, and indefinite future, signifying the influence of the human population on the stratigraphy of the planet as well as on earth’s primary biogeophysical systems (Crutzen 2002; Crutzen & Schwagerl 2011; Crutzen & Steffen 2003).

The campaigning has paid off – though not without controversy. The International Commission on Stratigraphy (ICS), appointed by the International Union of Geological Sciences (IUGS), has a designated Anthropocene Working Group who must determine:

  1. if the Anthropocene, as a geological time unit, makes stratigraphic sense (can we actually see a record of human influence in the sedimentary layers of the planet now, and will we still see it many, many years from now?);
  2. if it is a useful category for earth scientists as well as other disciplines, and if this conceptual utility should also be considered in its designation (could the term’s rhetorical use be as important as its scientific use?);
  3. when its beginning should be placed in the historical record (at the evolution of Homo sapiens, the advent of agriculture, the Industrial Revolution, post-Second World War, or at some point in the future?);5
  4. how it should be formally designated (as a ‘golden spike’ or by numerical date?);
  5. if it is best considered an age, epoch, period, era, or aeon (adapted from Waters & Zalasiewicz 2013).6

Prior to the advent of the Anthropocene idea, geologists generally agreed that the planet had been residing in the post-glacial Holocene epoch for approximately 11,000 years. Formal adoption of the Anthropocene would replace the Holocene as the category defining the earth’s present geological condition. The International Geological Congress has delayed ruling on the formal adoption of the Anthropocene until at least 2016 while scientists conduct further analyses (Waters & Zalasiewicz 2013).7

To heighten the anthropogenic aspect, scientific proponents of the Anthropocene idea claim that as a result of population growth and resource use, humans are now a geological force in and of themselves, driving planetary change at an unprecedented rate. Beyond climate change and biodiversity loss (leading to what some have called the Sixth Great Extinction [Kolbert 2014]), scientists point out that domesticated animals are now the majority of living vertebrates, and measured by global weight, only 5 per cent of all vertebrates are ‘wild’. Some stress that human activities have even changed the shape of the tectonic plates. Supporters of the idea therefore believe that the overarching context for all life on earth is now the Anthropocene. In other words, the controversial event is this: humans have been so influential as to necessitate a change of epochal categorization in the life history of the planet. For many earth scientists, this categorization matters because at stake is the morality of contemporary environmentalism and the hope for real political recognition of planetary change and uncertainty (Osborne, Traer & Chang 2013).

The Anthropocene idea has further significance for the social sciences and humanities, inspiring arguments across several fields about the shifting meaning of multiple forms of life and earth processes. For the postcolonial historian Dipesh Chakrabarty (200920122013), the Anthropocene idea itself (specifically climate change) represents a challenge to the primacy of the human in that the consequences of human activity can no longer be explained in terms of social theories of difference or political economy alone. He now sees the human as irrefutably bound up in the natural world through the collective effects of the species as a geological force. The human is therefore a tense figure within the narratives of the Anthropocene, doubly human and natural, and Chakrabarty argues that postcolonial historians and other humanists can no longer focus on the merely human aspects of human lives, and must instead accept that humanity is not ‘free’ from the vital realities of planetary existence.

In a distinct but sympathetic argument, the science studies scholar Bruno Latour makes the ironies of the Anthropocene idea explicit. He writes, ‘[W]hat makes the Anthropocene a clearly detectable golden spike way beyond the boundary of stratigraphy is that it is the most decisive philosophical, religious, anthropological and, as we shall see, political concept yet produced as an alternative to the very notions of “Modern” and “modernity”’ (Latour 2013: 77). He sees the Anthropocene as a confession of sorts of the fallacy that various forms of humanity and earth’s biogeochemical processes can each be examined in vacuums that do not contain the other.

The geographer Jamie Lorimer (2012) also speculates that the idea of the Anthropocene represents the nail in the coffin for the modern dichotomy between nature and culture that has been so central to Western environmentalism (but see also Crist 2013). He contends that the idea of ‘pure Nature’ has not gone quietly from the sciences; instead it has left a trail of confusion in its wake, what Robbins and Moore (2013) have labelled ‘ecological anxiety disorder’. Lorimer contends that there are a multiplicity of natures at play that stem from the variety of political-ecological scenarios in the world, and that these scenarios involve integrations of the human and nonhuman that cannot be uniformly described in an a priori fashion and that require radically new research approaches (see, e.g., Holm et al2013).

When it comes to taking up the provocations of the Anthropocene idea in scholarly depictions of the world, Irvine and Gorji note that the turn towards ‘Writing Culture in the Anthropocene’ is part of a broader move in the academy (2013; following Kirksey & Helmreich 2010). The environmental historian William Cronon is one well-known early exemplar of this Anthropocene turn in the humanities. His work, exemplified in publications like Nature’s metropolis (1992), explores historical socioecological relationships shaped by market institutions in the American Midwest using a methodological blend of ecological and economic history. He has argued that it would have been problematic to reinforce the boundary between human and nonhuman in his investigation of the growth of Chicago because neither city nor country can be understood as solely natural or unnatural.

In a more politically explicit vein, the geographer Nahan F. Sayre argues that ‘the key points to draw from the Anthropocene have less to do with when it began than how it affects the underlying assumptions that scientists make about understanding the world’ (2012: 63) and how these assumptions affect policy. He cautions that declaring the age of anthropogenesis should not lead to an assumption of a transhistorical ‘anthropos’ with no attention to the uneven distribution of Anthropocene responsibilities and impacts. Therefore, the Anthropocene necessitates questions of ‘socioenvironmental justice’ (2012: 67). Sayre’s work and my own are aligned in that he recognizes that the Anthropocene cannot be reduced to climate change alone and that the idea presents a number of opportunities for anthropological participation. He states, ‘[T]he challenge is to rebuild our conceptual scaffolding to reflect these novel realities’ (2012: 63).

The last few years have seen solidifications of scholarship around climate change, the proliferation of political ecology, and the rise of social studies of nature. The social sciences and humanities have begun to discuss the Anthropocene, engaging with the idea and its challenges and invitations for scholarship. But what about specifically anthropological engagements with the Anthropocene? What orientations are needed to explore anthropological puzzles like those I have begun to follow in The Bahamas? My hope is that we can craft new frameworks that will open doors for such an engagement, expanding the scope of the political ecology of global change.8

Anthropology and global change

In this section, I show some of the diverse ways that anthropologists already approach the discursive and material realities of global anthropogenic change. Of course, anthropologists have long been interested in various phenomena of global environmental degradation (Bodley 2002), and, of course, environmental change depends on ‘how we see evidence of change and the stakes at play in the perceptions of environments as natural or cultural’ (Cameron 2013: 105). Many scholars accept the planetary scaling of late twentieth-century environmental science, asking how local communities are involved with degradation as a locally enacted global phenomenon.

Since the Rio Convention on Biological Diversity in 1992, a broad-reaching topic in the anthropological investigation of global change has been biodiversity loss, and studies centred on biodiversity are still an important example of anthropology in the Anthropocene. Anthropologists have documented the knowledge and practices of rural and indigenous peoples that affect crop diversity and the existence of rare species. They have also shown how local people relate to biodiversity protection in ways that differ from mainstream international conservation efforts (Haenn, Schmook, Reyes & Calmé 2014; Orlove & Brush 1996; West 2006). Importantly, anthropologists have also had a great deal to say about the social production and material manifestations of biodiversity (Hayden 2003; Lowe 2006; Nazarea 2006; West 2006). This work delineates biodiversity as one of the most influential political forms of the 1990s, reshaping idioms of value, exchange, development paradigms, material realities, and rights in ways that have transformed North-South relations to this day. Further, anthropologists have shown that the scientific designation of biodiverse nature has salience for the circulation of multiple forms of capital. This work suggests that the way anthropogenic change is imagined, defined, and experienced has crucial implications for transnational flows of capital, knowledge, and social recognition.

Anthropogenic climate change has possibly surpassed biodiversity loss as the most widely recognized form of global transformation. The anthropology of climate change, as envisioned by Crate and Nuttall (2009), stresses protecting and respecting local cultures in the face of this phenomenon when it comes to adaptations, unpreventable impacts, and disasters. These scholars exemplify an action-orientated stance towards change, calling for anthropological engagement that can make local challenges visible aspects of international policy. Within this mode of research, also known as ‘climate ethnography’, anthropologists have a responsibility to explicate the local effects of global transformation in order to fill in gaps in Western scientific knowledge about anthropogenic change (Crate 20082011).

In a related vein, scholars like Lazrus and Rudiak-Gould have helped carve out a niche for an anthropological engagement with small island communities in the context of anthropogenic climate change. Lazrus (2012) argues persuasively that climate change has altered conditions for life in small islands, affecting islanders through a number of key environmental shifts, but also through the enactment of adaptive policies that circumscribe the sovereignty of affected peoples. For Lazrus, anthropological responsibility lies in reconfiguring international institutional understandings of island vulnerability so that islanders are not assumed to be inherently vulnerable. For Rudiak-Gould (20102013), climate change in small island states is both an issue of translation between international scientists and island citizens and a question of seeing the material consequences of change in islander environments. He argues that scientists can learn from island people when they examine how the information they present has been reinterpreted in local idioms. Scientists are then forced to see the ‘humanistic dimensions of this geophysical phenomenon’ (2010: 53) and to respond to material realities of change that may not be readily visible from their data sets or regional climate models (2013). For both scholars, the anthropologist’s task is to help find meaning in forms of change that combat scientific hegemony and colonial legacies.

Continuing the discussion, many scholars have advocated for more of a second-order perspective for the study of climate change (Lahsen 2005; Moore 2010b; Tsing 2005; Whitington 2012). For example, Lahsen (2008) is adamant that anthropologists should study those who populate the centres of power and generate knowledge and policy about the phenomenon itself. She argues that scientists, administrators, journalists, and officials do as much to shape climate change as an idea, discourse, and powerful frame for thought and action as do the marginalized peoples of the world. Along these lines, Barnes et al. (2013) have argued that engagements at this level allow for an understanding of the cultural dimensions and micro-dynamics of decision-making about climate processes and policies, and therefore for anthropological influence to be felt amongst people in positions of power.

Other topics for the anthropology of global change have included work on the scientific rationales and social realities of invasive species eradication strategies (Fortwangler 2009; Moore 2012); the critical analysis of spatial productions in the name of environmental change such as protected areas (West, Igoe & Brockington 2006); criticism of the crisis rhetoric of global change as an excuse to appropriate land and resources in carbon trading strategies (Fairhead, Leach, & Scoones 2012), and arguments about the nexus between ecological knowledge production and market-based extractive practices (Davidov 2012). Although this is by no means an exhaustive collection, these examples show the scope of recent anthropological work that takes on the idea of anthropogenic change in an era of planetary framing. But what about anthropological work (including sympathetic disciplines) that explicitly engages the Anthropocene idea as a social fact and material reality?

Anthropological writing that explicitly tackles the idea of the Anthropocene itself is relatively few and far between (though rapidly growing), but Carrithers, Bracken, and Emery (2011) use the term to label a ‘master narrative’ of endangerment, extinction, and crisis that helps dictate the social placement of species in the world of species protection and valuation. Sympathetically, Ogden et al. (2013) argue that it is crucial to study geopolitical outcomes tied to the transnational institutionalization of discourse and practice in the name of the Anthropocene, what they call global socioecological assemblages (following Ong & Collier 2005). They use the concept of global assemblages to describe market-driven, transnational environmental governance emerging as a means of managing life processes. Also emphasizing governance, Lovbrand, Stripple, and Wiman view the Anthropocene as a ‘central system of thought mediated by Earth System Science’ (2009: 10) new forms of research such as coupled natural and human systems. These projects then become ‘new political space(s) for government intervention’ (2009: 11). Going further, Howe (2014) describes (in the context of industrial alternative energy farms) how both experts and local people assert authoritative and ethical claims in the context of Anthropocene futures. ‘Anthropocenic ecoauthority’ therefore consists of ‘experiential, scientific and managerial truth claims’ about environmental knowledge (2014: 383).

As this work on various aspects of global transformation shows, anthropologists are situated to observe how the Anthropocene idea amalgamates multiple forms of anthropogenic change into an argument about the distinction of the contemporary world. Anthropology also shows that we must remain conscious of the multiple materialities entangled in this emergent cosmological ordering of reality. For example, Larkin (2013) points us towards the infrastructures that materially mediate much of the human relation to the nonhuman world. According to him, infrastructures are more than technical objects – they are poetic, semiotic, and aesthetic, constituting subjects and citizens while embodying the ‘collective fantasy of society’ (2013: 329). An anthropology for the Anthropocene would be attuned to the ‘politics and poetics’ of the material interventions made in the name of global change along with the political ecologies, discursive productions, modes of governance, justice, authority, and expertise that combine to constitute our planetary present.

Anthropocene anthropology

I see the Anthropocene as the most recent iteration of the positive feedback cycle producing ideas about planetary change: the more researchers and policy-makers promote anthropogenesis as a global issue with political stakes and the more transnational action takes place in its name, the more we will see shifts in understandings of global transformation, sociality, ecology, and landscape (or marinescape) formations on multiple levels. These will in turn inspire new alliances and materializations. We require frameworks that allow us to recognize the components and effects of this Anthropocene feedback cycle while they help reproduce locations like the Bahama Islands.

Returning to my anthropological puzzle in The Bahamas, I would like to propose concepts for the exploration of ‘Anthropocene spaces’ – the complex conjunctures that I hope will become the subject of an Anthropocene-aware anthropology. The puzzle of The Bahamas requires analytical categories and concepts – a framework – that can reframe global change and the Anthropocene idea as an anthropological object. For starters, global change predictions, driven by the work of scientists from the Intergovernmental Panel on Climate Change (IPCC) and others, have had far-reaching influence in the creation of political alliances for the Anthropocene. As I mentioned above, The Bahamas is a member of AOSIS at the United Nations. The forty-four AOSIS member nations come from all the ocean regions of the world, and the group now describes itself as ‘a coalition of small island and coastal countries that share similar development challenges and concerns about the environment, especially their vulnerability to the adverse effects of global climate change’ (Alliance of Small Island States 2013). The milieu in question within AOSIS is the small island, now thought of as an object about which it is possible to make a number of truth claims about its social, economic, and environmental fragility in the face of anthropogenic planetary change. Anthropocene political objects are scalable in the Bahamian context from particular islands, to the island nation, to the Caribbean island region, to the planet itself as a fragile ‘earth island’. Further, the forms of subjectivation available for island residents in The Bahamas now include the climate change refugee, facing the future possibility of ‘heading for the hills of Haiti’9 as the everyday experience of coastal erosion and sand replenishment is publicly linked to global change. AOSIS is one example of an alliance that hopes to promote small island subjectivity while facilitating transnational island adaptation measures.

To approach these political moves, the anthropological engagement of the Anthropocene requires a scope beyond the molecularization of recent work on bioscience (Rose 2006) and the sovereign anthropocentrism of concepts like biopower and biopolitics (Povinelli 2014; Rabinow & Rose 2006). These concepts must be remediated to speak to the Anthropocene as a social category that positions the nonhuman and biogeochemical processes as integral to the political understanding of life. To do this I borrow from Olson (2010), who coined ‘ecobiopolitics’, a concept acknowledging techniques of knowledge production and governance that focus on the milieu between environmental and human processes for the optimization of the milieu itself. Ecobiopolitics focuses attention on scientific and political strategies towards anthropogenic change that manage the idea of planetary ‘habitable space’ across scales and methodologically elide human and ecological research. Anthropogenic planetary change then becomes a form of global environmental imaginary within which it is possible for Olson’s understanding of ecobiopolitics to function through ‘truth claims based on knowledge of milieu processes, power relations that take milieus as their object, and the modes of subjecthood and subjectification that designate subjects as milieu elements’ (2010: 181, modifying Rabinow & Rose 2006). The Bahamas’ self-positioning as an AOSIS member signifies the positioning of its islands within an ecobiopolitical mode of knowledge and governance, subjectivation and development.

In light of the country’s commitments to Anthropocene alliances and projects designed to combat its fragility, The Bahamas is increasingly considered a ‘rich source of research’, in the words of a visiting marine scientist at a recent public meeting of the Bahamas National Trust. This means that emergent forms of reason can now be tested there through field research projects enacted by visiting researchers who are commonly conducting integrated ecological and socioeconomic studies about environmental change. One such project I participated in was the Bahamas Biocomplexity Project (BBP), an interdisciplinary amalgamation of researchers studying the archipelago’s marine biodiversity and species connectivity, the distribution of marine habitats, and the socioeconomics of fishing communities to ‘improve the design of networks of marine protected areas’ (American Museum of Natural History 2013). This kind of policy-focused, interdisciplinary work is indicative of the research paradigms attached to the Anthropocene idea in which methodologies are consciously designed to speak to ‘big picture’ issues of anthropogenic global change within ‘linked human and natural systems’ as opposed to studies of molecular or genetic processes in isolation (Colwell 1998). My time with the BBP was spent administering surveys to members of Bahamian fishing communities, catching answers as-catch-can on boats, dock benches, car rides, and at kitchen tables. As a member of the social science arm of the project, I had no field interactions with the biological teams collecting oceanographic, biological, and spatial data elsewhere in the archipelago. I came to realize that, methodologically, such teamwork often follows different patterns in space and time depending on the target of research: human or nonhuman, living or nonliving physical processes.

How should we characterize the forms of reason that anchor such ‘big picture’ research methodologies? I argue that within projects such as the BBP or the CCI (mentioned above), socioecological forms of institutional reason – what I label ‘socioecologics’ – frame human/environmental/nonhuman relations as coupled systems united in explanations of earth system dynamics and resource management planning. Some examples of socioecologics include complex adaptive systems theory (Holling 2001) and socioecological systems theory (Anderies, Janssen & Ostrom 2004; Berkes 2003). Popular socioecologics reframe research scope and method, creating novel interdisciplinary projects, but the form of socioecological projects can amplify or ameliorate disciplinary disparities and divides between researchers and the human and nonhuman others who inhabit the field. In other words, investigations of the Anthropocene idea must be aware of the form of socioecological reason that delineates thought and action around specific Anthropocene projects within a particular ecobiopolitical milieu.

In terms of other modes of human/nonhuman relation such as the process of reproducing a Bahamian export product through MSC certification, we must remember that commodity certification transforms the relationships of production between groups of people and between people and the things they produce (Bestor 2001; West 2010). These processes alter human and nonhuman beings in ways that make them amenable to recent Anthropocene markets. Sea creatures with a mottled carapace that are known as ‘crawfish’ in The Bahamas and sold as generic (but luxurious) white-fleshed ‘lobster’ in the United States and Europe are being moulded into ‘Spiny Lobster’, becoming scientifically measured and assessed as ‘stock’ that can be studied and rebranded at national and global levels.10 Fishers, too, are moulded into ‘stakeholders’ within the MSC system, continuing a process of fishery reorganization under the sign of global conservation begun in the 1980s and 1990s. The president of the Bahamas Marine Exporters Association has said that ‘with major supermarket chains in the US and Europe committed to buying only from countries that can prove their fisheries are sustainable, we realized MSC certification would be required to maintain market access for the Bahamian Spiny Lobster. This led to the rapid and wholehearted transition of the fishery’ (cited in Isaacs 2011).

An analytic beyond the human is useful here for understanding more than the co-constitution of biogeochemical processes and research project design. Anthropological attention to the emergent objects of knowledge, governance, and forms of reason adapted to the Anthropocene idea must also acknowledge the embodied relations that produce fisheries and creatures like Spiny Lobster and fishers. Tsing argues that the idea of human exceptionalism blinds us to the interspecies connections that make up our own lives within our bodies and in our surroundings (Tsing 2012; in homage to Haraway 20032008; and Kirksey & Helmreich 2010). Human species-being (the sense of human nature that concerns Chakrabarty [2009] in the Anthropocene) is not autonomous but is instead comprised of relations with other organisms moving within geochemical processes held together by diverse forms of dependency and love. Anthropocene ecobiopolitical and socioecological configurations (such as alliances based on geography, global science, resource management, etc.) manage humanity, geology, and biology in multiply produced landscapes that affect notions of value and relations of production and reproduction stretching from global markets to the state to the locality. Tsing refers to these networks as interspecies relations, but I call them ‘earthly relations’, as a reminder that there are ‘non-living’ components to consider when thinking about life (e.g. planetary geophysical processes, the ‘resonance’ of stones, and the movement of water [Ingold 2011; Kohn 2014; Raffles 2012]).

Within the assemblages and markets animated by the Anthropocene idea, there are myriad circulating stories that deserve anthropological attention. Examples of Anthropocene stories include the IPCC global change narratives that bind AOSIS members or the narratives of overfishing that link all fisheries in a global saga of anthropogenic decline. And, arguably, the task of the Anthropocene Working Group (see above) is to construct a plausible story about planetary change. Authoritative stories frame protagonists, perpetrators, and victims (human and nonhuman), and they help lay the groundwork that makes economic ventures like MSC certification or sustainable tourism viable in places like The Bahamas. While an attention to narrative may appear to abandon a commitment to material processes, I argue that such stories help constitute ecologies and socialities by bringing them into new kinds of socioecological and ecobiopolitical (earthly) relation.

The narrative power of what Latour (2013) has called ‘geostories’ is a useful analytic with which to tackle these circulating tales. Geostories reflect socioecological arguments about global change in narratives that stem from the teleologies of the earth sciences. They are meant to be accessible tales about the stakes and exceptionalism of the Anthropocene. Geostories simultaneously perpetuate ecobiopolitical discourses around global change – discourses that attempt to ‘reframe Anthropos’ (Palsson et al2013: 4) by narrating the Anthropocene as an effect of human species-being. Often these kinds of geostories can, in the words of Malm and Hornborg, obscure attention to the owners of the means of production who came to power out of a ‘constellation of a largely depopulated New World, Afro-American slavery, the exploitation of British labor in factories and mines, and the global demand for inexpensive cotton cloth’, which led to the rise of the steam engine and from there to our fossil-fuel-based economies (2014: 63). Even Chakrabarty (2013) contends that speaking about the collective ‘we’ of humanity should not imply that ‘we’ are politically one. As Latour (2013) points out, geostories are not harmonious tales but are instead tumultuous and crisis-ridden, steeped in the unknown.

Finally, I have observed that building models for living (and for tourist visitation) in locales such as The Bahamas involves struggle and negotiation between authorities and between authorities and marginalized groups. For example, the spread of marine reserve networks and the rebranding of Bahamian islands in speculative sustainable development markets align the country with global trends: transforming landscapes, infrastructures, and built environments to conform more obviously with prevailing concerns over greening and global change. Such Anthropocene worlding experiments (Roy 2011) can deepen social inequalities by appropriating space from coastal communities, and design models can also be misappropriated. An attention to designers and their plans for development, to resource management, scientific research, exploration projects, to the technologies that enable us to ‘see’ global change, and to various green markets and products will help open Anthropocene assemblages to scrutiny and intervention when necessary.

Therefore, I think an attention to design should be a major component of analysis as the thread that unites the interrelated themes of this framework and points us towards action. If, as proponents of the Anthropocene idea argue, the recognition of anthropogenic planetary change calls for the refashioning of human and nonhuman life on earth, then extreme care must go into redesigning ecobiopolitical configurations, socioecological forms of reason, and viable earthly relations on multiple levels (Latour 2008). The Anthropocene commitments of scientists, governments, and developers are already leading to emergent geostories and brand platforms that designers must draw together in their (co-)creations.

The interrelated concepts that I have chosen to help me explore my Bahamian anthropological puzzle – ecobiopolitics, socioecologics, earthly relations, geostories, and design – represent an amalgamation of environmental anthropology, critical science studies, and political ecology applicable to the evolving twenty-first-century concern with global change known as the Anthropocene. Such analytic reorientations help anthropologists explore events animated by the Anthropocene idea, from emergent political alliances and spatializations to modes of subjectivity and citizenship, from forms of scientific objectification and naturalization to shifting research methods and narratives, from green markets, products, and flows of capital to the materialization and embodiment of these ideas in spaces, places, bodies, and earthly relations. I contend that such recognition helps us identify how emergent ideas contribute to asymmetries and pervasive inequities, allowing anthropologists to intervene in arenas that were previously unavailable for thought. Further, recognizing the ways these conceptual arenas interrelate allows us to grasp the creativity and generativity of contemporary global change assemblages.

Conclusion

The International Geological Congress still has some time to deliberate before it rules on the ‘official’ designation of the Anthropocene. Official agreement on the existence of the Anthropocene as a geological category will not instantly change the way most of us think about planetary anthropogenesis. However, I believe it will spark further debate over the parameters of contemporary global change, inspiring more institutional initiatives and scientific engagement with policy. In other words, the Anthropocene feedback cycle could grow even more acute.

As these events unfold, anthropologists will certainly continue to respond to the social and material realities of global change, and, critically, to the Anthropocene idea itself as an important contemporary object and problem. I have argued that The Bahamas is one example of an emergent ethnographic area within the problematic of an ‘Anthropocene space’. Despite the fact that this seems to fly in the face of the Anthropocene as a planetary and temporal imaginary, it is now clear that global imaginaries and categories have powerful material and symbolic implications, contributing to the reproduction of particular locations, places, and scales. As Tsing has stated, ‘[W]e can investigate globalist projects and dreams without assuming that they remake the world just as they want’ (2000: 330). Anthropocene spaces like small islands are but one position from which anthropologists can begin to think the Anthropocene. And these spaces need not only be geographical locations, but they can also be locations of novel conservation interventions and laboratory situations, such as experiments in geoengineering, re-wilding, or de-extinction. I believe my conceptual bundle could handily be applied in these situations, with a great deal of room for modification and addition.

The work of an Anthropocene anthropology is needed in order to counter and complement the sciences of the earth system and global change research. Following Lovbrand et al., I think it is anthropology’s responsibility to ‘investigate the new forms of power, authority, and subjectivity formed within everyday practices of its own scholarship’ (2009: 12) as anthropologists are integrated further into interdisciplinary and transdisciplinary global change studies. Towards that end, frameworks like the one presented here can ground ethnographic engagement and collaboration and inform the task of reflexively ‘Writing Earthly Relations’ in the Anthropocene.

My research is slanted towards the products of travelling scientists, elite authorities, and green designers who mediate, circulate, and sell the Anthropocene idea in The Bahamas, and indeed these have been my primary informants over the years. However, I think this framework could be attuned towards less overtly ‘authoritative’ events and instantiations of Anthropocene ideas. Further, I hope I have shown that it is not only anthropogenic change that has material effects, as has been so thoroughly demonstrated by the sciences, but that the politics, forms of reason, relations, and narratives that the Anthropocene idea inspires are also materialized in ways that must be acknowledged and explored.

As I stipulated in the introduction, the background argument of this article has been that anthropology must retain its critical stance when confronted by institutional framings of global change. Again, along with Sayre, I call for a continued attention to science-based policy prescriptions that seek to limit the conceptualization of and possible responses to global environmental change. In other words, we must not participate in the erasure of real opportunities for justice and ethical awareness.

In closing, I ask, how ephemeral are the ideas that constitute today’s ‘ephemeral islands’? Despite the fact that there are anthropologists who consider the Anthropocene to be a trend-of-the-moment buzzword, I think that the Anthropocene idea as a problem space that configures locations around evolving notions of global change and human/nonhuman relations will stay with us for some time to come. There is too much political urgency and institutional attention attached to the idea for it to go quietly. I hope an Anthropocene anthropology will be there to help explore the multiplying puzzles of the epoch.

NOTES

1 Following Rabinow (2003) and Rabinow & Marcus (2008) on problematization and the contemporary.2 The Anthropocene idea is of recent origin, but the arguments leading up to its coining and conceptual coalescence have deep roots in transnational events of the last forty years and beyond with the creation of ‘the environment’ as a political category and its subsequent globalization. Parsing this history is not the goal of this article (but see Fortun 2001; Worster 2008).3 The Bahamas is also a British Commonwealth country and member of the Caribbean Community (CARICOM).4 The irony comes from the fact that Bahamians publicly debate the ‘Haitian problem’ of the illegal immigration of Haitians to The Bahamas.5 For more on the ‘start date’ controversy, which is beyond the scope of this article, see Ruddiman (2013).6 In general geochronology, an age is defined as an interval of several million years, an epoch is tens of millions of years, a period is somewhere between an epoch and an era, an era is several hundred million years, and an aeon is at least an interval of a half a billion years.7 The International Geological Congress (IGC) has been meeting since 1878 in three- to five-year intervals (IUGS 2009). The next meeting is in South Africa, in 2016, where the latest evidence for the existence of the Anthropocene will be marshalled by the Anthropocene Working Group to be voted on by the International Commission of Stratigraphy (ICS), the keepers of the geological timeline. The Anthropocene Working Group of the International Union of Geological Sciences and ICS is made up of approximately twenty-nine member scientists from fourteen countries (the United States, Spain, Germany, the United Kingdom, Switzerland, Brazil, Kenya, France, South Africa, Australia, Norway, Austria, Canada, and China). The disciplinary background of members includes archaeology, chemistry, geology, earth systems, and the earth sciences.8 Anthropologists have long concerned themselves with the impacts of humans on their environments as a historical and evolutionary question, and this is far too expansive a conversation to describe here. In this article, I am focusing on the Anthropocene idea as it is used by scientists today and as it is becoming popularized in the social sciences. This is a culturally specific idea of recent origins, and I am interested in investigating its current uses, implications, and materializations.9 For a discussion of climate refugees, see Collectif Argos (2010), McAdam (2009), and McKee (2011).10 The Bahamian lobster industry is many decades old, but MSC certification is a new iteration.

Artificial Stupidity and Artificial Intelligence in the Anthropocene


Bernard Stiegler

23 November 2018, Institute of Ereignis, Shanghai

For anyone wanting a precise analysis of what we refer to today as artificial intelligence, which seems now to have become the horizon of everyday life (and I will return to this question), it is necessary to begin from the following postulate: all noetic intelligence is artificial. This implies that there is such a thing as non-noetic intelligence. And it also implies that, generally speaking, noetic life is intelligent in a specific way, which is that of artifice.

I claim that there is non-noetic intelligence in the sense implied when Marcel Détienne and Jean-Pierre Vernant talk about metis, but also in the sense invoked by Kevin Kelly when he wrote an article that presented forms of life, of whatever kind, as forms of intelligence, where each of these forms has evolved in a different way over the last three billion years or more. Speaking in this way is for Kelly a matter of opposing what he calls the myth of super-intelligence, but it is also to speak against Descartes: it is to posit that life is never just machinic – and here we should also mention Georges Canguilhem’s ‘Machine and Organism’.1

Intelligence, here, whether in its ‘natural’ or ‘artificial’ forms, but I prefer to say in its organic or organological forms (I will clarify this a bit later on), is the accomplishment of a goal or an aim. There is no necessity at all for this goal to be a conscious representation, as Francisco Varela shows in a drawing in which he ridicules this kind of ‘representational’ hypothesis. What is involved with noetic intelligence, however, is, in principle, access to consciousness, insofar as it has the capacity to access what Heidegger called the as such – Heidegger being himself someone who deconstructs the metaphysics of representation. Intelligence, whether noetic or otherwise, is in a general way what orients behaviour: it constitutes an animation, as Aristotle will say in On the Soul, in which vegetative, sensible and noetic souls draw intelligence from what he calls the ‘first unmoving mover’, and where the intelligence that is the soul is above all movement, which is also to say, phusis.

In order to precisely distinguish (without opposing) the organic (vegetative and sensible) forms of intelligence from the organological (noetic) forms, we must firstly recall what Aristotle remained unaware of, namely that, some three million or so years ago, there arose the conditions for what would later, some forty thousand years ago, become noetic intelligence, in which Georges Bataille would recognize himself, and in relation to which he said: here it is we who begin, those who painted these animals are our ancestors, our father, this is evidently so, it is obviously so, and recognizing this evidence is a key feature of noesis itself. Here is exactly what he writes in Lascaux, or The Birth of Art:

It is ‘Lascaux man’ about whom we can surely say, and for the first time that, making works of art, he evidently resembled us, he was one of us, our fellow man.2

Bataille will go on to say that the kind of intelligence involved in the work of art is the intelligence of play – I will not develop this point now, but it is fundamental in order to understand what it means for the question of noetic imagination (and I will discuss this next year in Hangzhou). Having said this, we can begin to understand why what we today refer to as artificial intelligence is a continuation of the process of the exosomatization of noesis itself, such as it begins firstly with fabricating exosomatization, making things by hand, and continues with hypomnesic exosomatization, as that which makes it possible to access lived experiences of memory and imagination, which have accumulated since the origin  of the play of works, as Bataille considers them, and which engender, in passing through writing, instruments of observation, calculating machines whose principles were established by Leibniz, and analogue technologies, which form the basis of the culture industries – and here the question of their role in the ‘post-truth era’ arises as never before. All of this then, writing, telescopes, calculating machines and the analogue recording technologies of the culture industries, all of this has generated a perpetual and techno-logical evolution of what Kant called the faculties – whether they are lower, that is, functions of noesis, or whether they are higher, and thereby constitute faculties in the sense we refer to them in universities, and which regularly enter into conflict.

Why do such conflicts arise? Because there are exosomatic evolutions of the hypomnesic supports of noesis, and this generates tensions – which can be social as well as noetic.

Two years ago in Nanjing, I tried to show (and I will come back to this next year) that what Kant called the lower faculties – intuition, understanding, imagination and reason, which are put to work by the higher faculties that are those of knowing, desiring and judging – are functions that are produced through the process of their exteriorization, which Hegel was already able to see, but without truly seeing it. It is Marx who will be the first to understand this, and it will then be reformulated by Lotka, who will do so from a biological standpoint and by coining a new term: exosomatization, or exosomatic evolution and exosomatic organs. Here, the intelligence of the body is produced in being supplemented, inasmuch as it makes possible an exteriorization of experience, and the constitution of what I call (using Husserlian terminology) collective secondary retentions: the latter are retained in individual memories, but they are retained there collectively, forming what we also refer to as knowledge, which can be transmitted from generation to generation, and which metastabilizes the conditions of life – these conditions of life being negentropic, that is, struggling against the entropic effects of human behaviour, which is something we discover in the Anthropocene, through the analysis of what the IPCC calls anthropogenic forcings, which fundamentally threaten life, and in particular noetic life – life that is worthy of being lived by a noetic soul. All of this is what leads to a life that is unworthy of noesis – and ultimately becomes incompatible with life as a whole, as the 15364 signatories of a recent scientific text declare.

It is in this context, at the end of the Anthropocene – and these scientists indeed tell us that it is reaching its end, which must then also be ours – that we see the advent of artificial intelligence as an ordinary reality of everyday life. What then should be the function of what is today called ‘artificial intelligence’, where this refers to a technology of reticular, ubiquitous super-computing that automates the majority of processes by which behavioural flows are managed, where this has fundamental effects on both modes of production and modes of exchange in all their forms, and where, in its current stage, these have been transformed into functions of consumption?

What we today call artificial intelligence is not what was on the horizon of the Macy conferences, the project of which was formulated in Dartmouth by Marvin Minsky with Claude Shannon, Allen Newell, Herbert Simon, and so on. It is a reticular AI, based on what Clarisse Herrenschmidt has called reticular writing, which is linked to the networking together of three and a half billion individuals – via an apparatus that becomes exosopherical, constantly evolving, and now based on the ‘platform capitalism’ described by Benjamin Bratton – and that makes possible the production and exploitation of what I call ‘digital pheromones’.

The possibility of such digital pheromones was in a way already raised by Norbert Wiener in 1948, when he worried about the possibility that cybernetics could give rise to what he called a ‘fascist ant-state’.3 That the human could regress to the stage of the ant is a possibility contained in the fact that this human abandons his knowledge – his knowledge being the path by which he must struggle against entropy. That such a possibility exists, that is, that cybernetic exosomatization can generate an industrial artificial stupidity, is the question that must guide us here. As soon as intelligence becomes artificial, that is, as soon as it is made possible by artefacts and makes these artefacts possible – due to that astonishing faculty of dreaming which, according to the palaeo-anthropologist Marc Azéma, characterizes the human being: he posits that man dreams, as do animals, but that he also does so by producing, drawing and writing, by day-dreaming, such an ex-pression being the beginning of a process of exo-somatization by which man realizes his dreams. The faculty of dreaming is, then, here the faculty of the realization of dreams, and such is noetic intelligence according to Paul Valéry.

But as soon as it becomes artificial, such intelligence can also generate an artificial stupidity: the pharmakon that is the artifice thereby engendered can lead to regression and to self-destruction. Such artificial stupidity is what Alvesson and Spicer describe as ‘functional stupidity’, in a well-known article that has since become a book – and it also generates what Tijman Shep describes as ‘social cooling’, which John Pfaltz describes as an increase in the rate of entropy in social networks. This artificial stupidity, therefore, is also a technique for the production of lures and traps to in some way deceive humans, but here, beyond stupidity, we must also refer to the necessity of putting faults or accidents into music, as was the case with software created by IRCAM, which produced only absolutely ‘right’ notes – for example for the Queen of the Night aria in Mozart’s The Magic Flute – but the ‘music’ this produced was unbearable.

And this is an issue we also see with trading software – which raises the question of vertus and of the necessity of imperfection, that is, the necessity of negentropic locality – which we must interpret via John Stuart Mill and the necessity of diversity. Artificial stupidity also means cognitive overflow syndrome, that is, the functional destruction of attention, or, again, it is what worries Adam Smith in 1776 in The Wealth of Nations.

The possibility of artificial stupidity is what characterizes artificial intelligence, which, as we have already said with Kevin Kelly, can be distinguished from natural intelligence. Natural intelligence cannot commit acts of stupidity: it can only fail, which means, ultimately, to die. Taking up a thesis of Nick Bostrom – but we could also refer here to Bergson, who thinks intelligence in terms of a relation to action – Kelly himself argues that life in general amounts to a series of conquests of intelligence. He argues this while criticizing the perspective of those he calls ‘singularitans’, who maintain five assumptions which, when examined closely, are not based on any evidence.4

The first of these ‘misconceptions’, and the most common, begins with the common misconception about natural intelligence. This misconception is that intelligence is a single dimension. Most technical people tend to graph intelligence the way Nick Bostrom does in his book, Superintelligence – as a literal, single-dimension, linear graph of increasing amplitude. At one end is the low intelligence of, say, a small animal; at the other end is the high intelligence, of say, a genius – almost as if intelligence were a sound level in decibels […] with fish evolving into reptiles, then up a step into mammals, up into primates, into humans, each one a little more evolved (and of course smarter) than the one before it.

So the ladder of intelligence parallels the ladder of existence. But both of these models supply a thoroughly unscientific view. […] A more accurate chart of the natural evolution of species is a disk radiating outward, like this one first devised by David Hillis at the University of Texas and based on DNA. […] Every one of these species has undergone an unbroken chain of three billion years of successful reproduction, which means that bacteria and cockroaches are as highly evolved as humans.

Into this ‘mandala’, however, we must also introduce the perspective of Alfred J. Lotka, for whom ‘natural’ intelligence becomes ‘artificial’, which is also to say, discovers the possibility of its own stupidity, as highlighted by Arnold Toynbee – when the morphogenesis that is endosomatic organogenesis continues outside wet tissue, and does so as exorganogenesis. The latter generates exosomatic organs that modify the trajectory of motor acts, such as occurs with the flint tool, some of which are arrows capable of travelling at 350 kilometres per hour, and today’s rockets, which launch themselves to escape velocity – twenty-eight thousand kilometres per hour – are the continuation of this capacity in a direction that opens up exospherical spaces. But in addition, these exosomatic organs also engender accumulations of psychic retentions, which thereby become collective and constitute what Roger Bartra calls an ‘exocerebrum’ and what Karl Popper calls World Three and objective knowledge.

This third world, however, is the world of what I call hypomnesic tertiary retentions, a world composed not just of exosomatic organs but of retentional accumulations, and where Lotka shows that these are orthogenetic, that is, bearers of non- Darwinian selection processes, making possible the establishment of scalar relations between different orders of magnitude, something completely different from, for example, relations between cells, organs, bodies, milieus and so on. Here we should really turn to Durkheim and to his book, The Elementary Forms of the Religious Life, in which he studies totemism, but I no longer have time to do so now. But we should also note that échelle as ladder, which is also the ladder dreamed of by Jacob, who has a primordial role in Judaeo-Christian monotheism, then becomes échelle as scale, and technologies of scalability are at the heart of those ‘economies of scale’ characteristic of the industrial and capitalist stage of exosomatization. Furthermore, platforms that utilize and develop reticulated artificial intelligence are based on specific technologies of scalability, managing multi-scale data ranging from infra-organic medical ‘nanomachines’ to exospherical infrastructures capable of handling medical data at the scale of the technosphere.

It is worth noting that it is on the basis of totemic classification that Durkheim posits that the Aristotelian and Kantian theory of the categories should be completely rethought. Now, the biosphere may be one scale located within the cosmos. But to this we must add the fact that, from the moment such changes of scale and arrangements of orders of magnitude arise, which is something that occurs with the exosomatic organs that are technical objects in all their forms (including language), from this moment, this biosphere becomes a technosphere. Within this technosphere, moreover, entropy, negentropy and anti-entropy, whose local equilibriums had metastabilized over the course of three or four billion years, find themselves totally overthrown by those exosomatic organs that are pharmaka, that is, organs that can as easily increase entropy as contain it, defer it and transform it through the ‘art of living’, as Alfred Whitehead put it. And the function of artificial intelligence is to in this way minimize entropy and increase negentropy and anti-entropy.

Artificial stupidity, then, is what persists in accelerating entropy instead of deferring it, and does so by destroying knowledge, which, alone, is capable of generating positive bifurcations. It would be entirely possible to take advantage of the analytical possibilities of algorithms in order to defer entropy. But in order to do so, it would be necessary to modify data structures, to press algorithms into the service of the constitution of deliberative scales reconstituting neganthropic knowledge, that is, dialogically transindividuated knowledge, and to make automation serve disautomatization within the framework of a new macro-economy in which value would be defined according to the increase of negentropy. In the current model, however, the criteria of value are entropic.

Behind this question, there are those of the relationships between calculability, locality, incalculability and deliberation – which is equally to say, those of the relationships between understanding, imagination and reason. In Automatic Society, I have argued that algorithms constitute a hypertrophy of the understanding – and that the latter is always artificial, and based on tertiary retentions inasmuch as they configure the schematism and the categories. These questions of epistemology and technology, of the industrial future and new macro-economic models, must all be brought together. It is precisely in order to do so that a program is currently under development in the Plaine commune territory, in the northern suburbs of Paris. And in terms of the question of macro-economics – which is also a question of the function of knowledge and therefore of the episteme in Foucault’s sense and of epistemology in Bachelard’s sense – it is an attempt, in the epoch of algorithmic and articulated artificial intelligence, to draw conclusions from Marx’s statements about fixed capital and the general intellect in the Grundrisse.

I argued earlier that with Kelly’s model, inspired by Hillis, it is necessary to specify the conditions of the passage from natural intelligence to artificial intelligence. I would like to conclude by adding some further remarks on this point.

  1. We must think this passage both with Whitehead and with Canguilhem, with respect to biology for example, and more generally with respect to the role of knowledge in the technical form of life, and as a vital function that can be thought only starting from biology, but precisely as what requires that which is no longer only biological, and which leads Georges Canguilhem to make statements that are quite close to being post- Darwinian and very close to those of Lotka concerning orthogenesis.
  2.  We must specify the question of metis and distinguish it from noesis: cognition, in the sense that this word has in the so-called ‘cognitive sciences’, is not knowledge in Popper’s sense. The passage from cognition to knowledge requires an exosomatic exteriorization and the constitution of what Leroi-Gourhan calls a third kind of memory, very close to what Popper calls World Three, and what I myself call the epiphylogenesis that forms with the accumulation of tertiary retentions. It is this question of exosomatization that Kelly completely ignores when he writes that:

We contain multiple species of cognition that do many types of thinking: deduction, induction, symbolic reasoning, emotional intelligence, spacial logic, short-term memory, and long-term memory. The entire nervous system in our gut is also a type of brain with its own mode of cognition. We don’t really think with just our brain; rather, we think with our whole bodies. These suites of cognition vary between individuals and between species. A squirrel can remember the exact location of several thousand acorns for years, a feat that blows human minds away. So in that one type of cognition, squirrels exceed humans. And yet:

Your calculator is a genius in math; Google’s memory is already beyond our own in a certain dimension. We are engineering AIs to excel in specific modes.

But these specific modes are only functions. It is not just a question of functions, but of faculties – if we take it as given that we must rethink the concept of faculty from the exosomatic perspective.

… the faculties are social, and not just psychic, and that is the whole issue involved in the conflict of the faculties.

Here we should read Ignace Meyerson’s Les fonctions psychologiques et les oeuvres, along with Vernant. Now, when Kelly writes that:

In the future, we will invent whole new modes of cognition that don’t exist in us and don’t exist anywhere in biology. When we invented artificial flying we were inspired by biological modes of flying, primarily flapping wings. But the flying we invented – propellers bolted to a wide fixed wing – was a new mode of flying unknown in our biological world.

When Kelly writes this, what he describes is precisely exosomatization, but he does not see it as such, and he does not see in what way it stems from the works produced during the Upper Palaeolithic, upon whose appearance Bataille meditates. ‘To build machines capable of beating humans’: this is the very goal of exosomatization. Why would we bother to make an automobile – or a bow and arrow – if these exosomatic organs were not quicker than humans? Here, however, the question is of noetic functionality. What indeed is noesis? It is what struggles against the perverse effects generated by exosomatization, but always by generating other processes of exosomatization. This is what Freud describes in Civilization and Its Discontents.

But in that case, it is not just a matter of the exosomatization of the exosomatic organisms that we have been ever since the dawn of hominization: it is also a matter of social organizations. And the latter amount to complex exorganisms, composed of the simple exorganisms that we are, which together form social groups of longer duration than the individuals who form them, as is the case for all civilizations. Such complex exorganisms are, however, prone to becoming massively anthropic, and they can therefore collapse, and today, more than ever, the role of politics consists in struggling against this pharmacological tendency.

Kelly eventually points out that the ‘Turing machine’ and ‘the Church-Turing hypothesis’ are misleading:

no computer has infinite memory or time. When you are operating in the real world, real time makes a huge difference, often a life-or-death difference. Yes, all thinking is equivalent if you ignore time.

But this indicates that what matters here are scales of time – as well as scales of space, and hence of speed.

The only way to have equivalent modes of thinking is to run them on equivalent substrates. [The] only way to get a very human-like thought process is to run the computation on very human-like wet tissue.

What is at stake in the organic tissues of humans, that is, what is at stake in their bodies, is, however, their relationship to death, where the locus of this relationship does not just reside within this body, but, precisely, within what I call the noetic necromass, that is, within what Popper called World Three, which means for example the Trinity College library in Dublin, which is being shifted onto new substrates that require a total reconsideration of the conditions of a new era of exosomatic noesis, themselves fundamentally composed of organizations – without which it will be impossible to avoid collapse.

No thought that in fact thinks thinks like any others, and this is what points to the real challenge: anti-anthropic bifurcation is what exceeds all calculation – and the question is the function of calculation and its limit in a neganthropic field, that is, a localized field, whereas the generalization of calculation, and the totalizations to which this generalization gives rise in this or that locality, destroys this locality5 – and this locality is the biosphere itself, in its relation to the cosmos, a question that was opened in these terms by Vernadsky in 1926.

The biosphere is the condition of biodiversity. Today, the question is how to make the technosphere the possibility of a new noodiversity.

5 The question is: where is the limit of intelligence? Is it not clear that this is a matter of entropy – and of entropy within a finite locality? The limit is not quantitative, according to Kevin Kelly: for example, it is ‘not on a Moore’s law rise. AIs are not getting twice as smart every 3 years, or even every 10 years’. And to shift these limits, Kelly posits that ‘we should engineer friendly AIs and figure out how to instill self-replicating values that match ours’. But the question is here the categorization that is accomplished along with the algorithmic => a new ‘transcendental deduction’ of algorithmically generated categories.
