In this blog, originally published as the ICEHO pages in Global Environment 17.3 Jonatan Palmblad advocates for a renewed scholarship of synthesis – the ability to bridge theory and practice, history, present and future – and even the physical and the metaphysical
It was the Spanish-American philosopher George Santayana who observed that ‘Those who cannot remember the past are condemned to repeat it’. Frequently invoked, if often unattributed, this aphorism gives credit to the work of historians even in times when usefulness is commonly equated with innovation and invention. Still, Santayana’s pithy phrase begs an important question: what is there to learn from history, other than what not to do? Though circumstances have changed since he wrote in the early twentieth century, I would argue that earlier, even long-neglected, approaches, ideas and critiques can still help our engagement with the present and shape the future – that they constitute a ‘usable past’.[1]

All historians know that thinkers and ideas are influenced and circumscribed by the contexts of their times. Sometimes, then, it is helpful to adopt what Friedrich Nietzsche called ‘untimely’ (unzeitgemäße) ways of thinking – or to get ‘unstuck in time’, as Kurt Vonnegut had it.[2] In other words, there can be benefits in treating the arguments and commitments of earlier scholars as potential sources of insight into current concerns. At the very least, this prompts us to consider the affairs and problems of the present from a different angle, and it would be remiss to rule out the usefulness of such perspectives in advance.
Here I want to speak a word for the scholarship of synthesis – a form of interdisciplinarity that preceded the widespread use of the term, but that was largely shouldered aside by enthusiasm for the endless promise of scientific research after World War II. ‘This is an era of specialists, each of whom sees his own problem and is unaware of or intolerant of the larger frame into which it fits’, wrote Rachel Carson in 1962.[3] Synthesis resists and overcomes this still escalating fragmentation of knowledge – a hallmark of late modernity – and, at this conjuncture, when the idea of interdisciplinarity is widely embraced but there is little consensus about what it is and how it can be achieved, historical synthesis offers a fine example of the insights to be gained from the broad-ranging integration of disciplinary knowledges and approaches.
The American public intellectual Lewis Mumford (1895–1990) exemplifies the practice of scholarly synthesis.[4] A mid-twentieth century ‘Renaissance man’, and a remarkable scholar who taught at MIT and other prestigious universities without so much as a bachelor’s degree, Mumford’s curiosity ranged across almost all known subjects, without losing sight of how they relate to one another.[5] A voracious reader, he was also a prolific writer, and through eight decades (between the 1910s and the 1980s) he published over a thousand works. Mumford was moreover a prominent public intellectual, whose career turned on his youthful conviction that modern society was heading towards ecological and social disaster. Looking back at his work in old age, he characterised his own thinking as ‘ecological’, invoking both the discipline of ecology and what he believed to be the fundamental interconnectedness of ideas and subjects – with each other and with the world itself.[6]
Just as Mumford described the polymath George Perkins Marsh’s Man and Nature (1864) as the fountainhead of the conservation movement, Mumford might be considered one of the wellsprings of environmental history.[7] Marsh used history to describe the increasingly dysfunctional relationship between western civilisation and the natural world, and Mumford conducted similar critical work from an even more multi-faceted perspective, generally considering physical, ecological, technological and social environments together. Mumford’s was not just a generalist scholarship that resisted the growing tendency towards specialisation; it was methodologically rooted in the idea that human–environment interactions can only be understood properly through an interdisciplinary outlook. This idea was itself historical and came from his eclectic mentor, the Scottish biologist and sociologist Patrick Geddes (1854–1932), who had sought to synthesise science and knowledge to improve the human environment – and who had introduced Mumford to Marsh’s work in 1920.[8] Both Geddes and Mumford believed that a historical understanding of wide ecological regions, which took ‘natural’ and social factors into account, was necessary for the democratic planning of cities. Though Geddes was simultaneously more practical and theoretical than his acolyte, Mumford expanded his mentor’s gaze beyond the region of immediate concern. If Geddes regarded the history of human–environment interaction as an aid to good town planning, Mumford used what we now call environmental history to better understand human civilisation and its challenges. This has been acknowledged by some. For example, Ramachandra Guha argued three decades ago that Mumford’s Technics and Civilization (1934) and The Culture of Cities (1938) ‘need to be read as essentially ecological histories of the rise of modern Western civilization’.[9] Indeed, these and many of Mumford’s other works deal with how the ‘West’ became ecologically, socially and economically unsustainable.

Mumford was both more and less than an environmental historian, because he avoided a resolute focus on ecological concerns in order to relate such problems to other factors in history. This generalist perspective led him to understand history in terms of complexes: socio-techno-environmental wholes in which humans, ideas, resources, landscapes, techniques and tools interact.[10] This is not the only way one can do environmental history, but these ‘complexes’ come close to what leading American practitioner John McNeill has dubbed ‘clusters’ – ‘new combinations of energy sources, machines, and ways of organizing production’.[11] Such a way of thinking is ‘holistic’ in that it considers the larger and paradigmatic wholes in which the phenomena of everyday life are situated.[12] This approach does not preclude the study of phenomena in their own right; instead, it offers a broad context that includes consideration of ideas, ideology, knowledge and discourse. So, ideas are engaged without ignoring the material and ecological worlds in which they are situated – while cultural and ideological environments are recognised as essential aspects of the human environment. In sum, Mumford’s ‘complex’ contextualisation offers a useful theoretical ‘tool’ for thinking about the environmental past.
Mumford’s oeuvre also points, usefully, to the importance of giving knowledge practical value. Advocacy and activism are important goads towards the systemic changes needed to address the biodiversity, climate and other crises that loom so large today. Crucially, however, environmental historical expertise can also help by illuminating paths towards the realisation of more just and sustainable futures for all planetary life. Mumford learned the importance of planning from his Scottish mentor and adapted Geddes’s ‘regional survey’ method to map out the spatial and temporal contexts of cities and towns while seeking to identify ways of improving lives lived within them. This required synthesising research from many disciplines, including history,[13] and Mumford, a committed ‘generalist’, typically undertook this integrating work himself.[14] Many environmental historians have followed his lead, but relatively few have emphasised the practical utility of their synthesising endeavours. Environmental historians are the obvious inheritors of Mumford’s elaboration of regionalism, that sowed the seeds of what is now more aptly called bioregionalism and of the task that Geddes assigned to sociologists: coordinating and synthesising knowledge on socio-ecological regions.[15] Though the term gained credence long after his passing in 1990, Mumford’s relevance to discussions of the ‘Anthropocene’ is also worth considering. Regardless of earth scientists’ doubts about the Anthropocene as a geological epoch, the idea marks undeniable anthropogenic processes of earth transformation. Still, questions remain about how this epoch came to be and how to ensure survival through the changing circumstances it will entail. Almost a century ago, Mumford was building on the prescient work of G.P. Marsh to argue that western civilisation was undermining its ecological foundations. Rather than simply pitting ‘man’ and ‘nature’ against each other, however, Mumford emphasised how all-too-powerful technologies and narrow understandings of science and knowledge are central to the problems of planetary survival. In Mumford’s view, the material means at the disposal of modern humans, and the ideological ends we strive for – such as growth, control, and expansion – were (and are) both essential components of the ecological crisis. In his last academic works, Mumford coined the term ‘megamachine’ to describe the current paradigmatic complex of social organisation, ideas and technology. To effectively resolve the ecological crises that he saw developing through his final years, he argued the need to rethink technology altogether. In a nutshell, Mumford aspired to change modern societies’ relations to the world by the embrace of new technologies informed by older, less devastating practices and attitudes as well as by organic life itself. This approach surely demands deep knowledge of history and the humanities – making these attributes more germane than ever.[16]
The humanities have a key role to play in assessing, limiting and changing the terms and implications of our present conjuncture, and following Mumford’s lead by thinking historically across disciplines will – I believe – facilitate the necessary discussions between specialists. For example: neither modern global society nor today’s ecological crises would exist without humanity’s increasingly powerful tools and layered social organisation, and Mumford’s theory of the ‘megamachine’ anticipates contemporary technological explanations of the Anthropocene such as the ‘technosphere’, the ‘Technocene’ and even the ‘Capitalocene’. These concepts and much recent work in Science and Technology Studies have extended and refined Mumford’s focus on socio-techno-environmental complexes, but his synthesising framework and plain-language arguments retain (and increase) their value as the Anthropocene concept fragments and understandings of the crisis are shrouded by fast-proliferating specialist terminologies.[17] The nature of the Anthropocene demands synthesis, both for understanding its complexity and for amassing the joint effort needed to thwart the destructive processes behind it.
Environmental historians will hold disparate views of Mumford’s work. Some will find it fascinating and useful; others will be dismissive. Not everyone wants (or needs) to wrestle with deep cultural explanations of the ecological crisis. Not everyone wants (or needs) to be highly interdisciplinary. Not everyone wants (or needs) to articulate practical solutions to pressing problems. And that is fine. As John McNeill has indicated, ‘Usefulness in the context of today’s problems should not be a requirement for historians’. Environmental historians do not have to be useful – but there are many opportunities for those who so wish to be just that.[18] Conversely, some students of contemporary crises might find that earlier engagements with similar issues are of marginal value. Why go back, they might ask, to old notions and thinkers, when we now have so many new ideas and perspectives? Certainly we are now overtly conscious of much that earlier scholars ignored – especially issues of Indigeneity, feminism, colonialism and social and environmental justice. Yet it is also fair to note that much inclusive and theoretically advanced research – although of great import – seems to have little impact on the biogeophysical and social crises of our times. We understand, now more than ever, just how deep, threatening and inequitable the causes and consequences of these crises are, but they and the processes that underlie them keep escalating. Perhaps, then, it is time to set aside the hubris of high modernity, to acknowledge the wisdom of the elders by adding the best and most pertinent ideas and perspectives of earlier scholars to our ever-developing ‘toolbox’ of environmental-historical inquiry.
Knowing the use and limitations of conceptual tools makes it possible to bring the past alive without regressing into reactionary and naive nostalgia; to remain critical of the past without discarding what is useful and needed; to apply and refine integrative approaches that specialised research has rendered obsolete from its own fragmented vantage point. This certainly applies far beyond the specific case of Lewis Mumford, important synthesiser though he was. In history, there is no lack of voices forgotten, neglected, ignored, silenced and oppressed – and many of these voices still have much to say![19] As Indigenous Brazilian Kayapo scholar Kaká Werá suggests, the increasing loss of ancestral knowledge of our own naturalness might be the very root of the ecological crisis.[20] History may help to avoid the repetition of failures, as Santayana had it, but it is also replete with positive, critical and imaginative ideas that we need to engage and build upon. In particular, I would argue that those who put synthesis and wholeness first – rather than analysis and specialisation – have fertile seeds from which to grow the understanding needed to address our current socio-ecological dilemmas, and that historical critiques and solutions provide rich soil in which they might thrive. The scholarship of synthesis can help us better understand how we ended up in our current situation and guide our engagements with the present. As such, it is one of history’s most valuable resources – and an essential feature of environmental history’s usable past.

[11] McNeill’s conception of ‘energy regimes’, paradigmatic examples of clusters, resemble what Mumford understood as phases of ‘technics’ (e.g. paleotechnic, neotechnic, biotechnic phases). See J.R. McNeill, Something New Under the Sun: An Environmental History of the Twentieth-Century World (New York: W.W. Norton & Norton, 2001), pp. 296–97. Mumford also emphasised the ideological components of such constellations. This is a key idea in Mumford, Technics and Civilization.
[12] One might perhaps think of these also as ‘assemblages’ or what Michel Foucault called a ‘dispositif’ (sometimes rendered as ‘apparatus’ in English), though there are many understandings of these terms.

[16] The idea that we must rethink technology is clearly expressed already in Technics and Civilization, but his final rendition of the argument was that a ‘biotechnics’ had to replace the current ‘megatechnics’ as the prime mode for organising human societies. See especially the two volumes of The Myth of the Machine. For a similar idea, see the notion of ‘intermediate technology’ in E.F. Schumacher, Small is Beautiful: A Study of Economics as if People Mattered (Tiptree: The Anchor Press, 1973), pp. 143–44.
[17] The many neologisms and alternative notions to the Anthropocene have, in the words of Helmuth Trischler, served as a ‘trading zone’ for ideas, but, if humanity’s ecological crisis is to be resolved, these disparate explanations and theories must become complementary rather than competing.

Trischler, ‘The Anthropocene: A challenge for the history of science, technology, and the environment’, NTM: Zeitschrift für Geschichte der Wissenschaften, Technik und Medizin 24 (3) (2016): 309–35.
