3599. James Lovelock Dies at 103

Pearce Wright and Jim Bradford, The Guardian, July 27, 2022

James Lovelock

The scientist James Lovelock’s discoveries had an immense influence on our understanding of the global impact of humankind, and on the search for extraterrestrial life. A vigorous writer and speaker, he became a hero to the green movement, although he was one of its most formidable critics.

His research highlighted some of the issues that became the most intense environmental concerns of the late 20th and early 21st centuries, among them the insidious spread through the living world of industrial pollutants; the destruction of the ozone layer; and the potential menace of global heating. He supported nuclear power and defended the chemical industries – and his warnings took an increasingly apocalyptic note.

The scientist James Lovelock’s discoveries had an immense influence on our understanding of the global impact of humankind, and on the search for extraterrestrial life. A vigorous writer and speaker, he became a hero to the green movement, although he was one of its most formidable critics.

“The planet we live on has merely to shrug to take some fraction of a million people to their deaths,” Lovelock wrote in 2006. “But this is nothing compared with what may soon happen; we are now so abusing the Earth that it may rise and move back into the hot state it was in 55m years ago, and if it does, most of us, and our descendants, will die.” In a speech to the Royal Society, he described the 2007 report of the Intergovernmental Panel on Climate Change as “the scariest official document I have ever read”.

Lovelock, who has died on his 103rd birthday, was best known through the Gaia theory, a controversial idea that he proposed in the 1960s and developed with the US biologist Lynn Margulis in the 70s. They suggested a radically different way of looking at the evolution of life. Their proposition challenged the view of Earth as just a lump of rock, a passive host to millions of species of plants and animals that simply adapted to their environment. Gaia held that those countless millions of organisms not only competed, but also cooperated to maintain an environment in which life could be sustained: a process of co-evolution.

It was a conjecture that jarred with many scholars, such as Richard Dawkins, the evolutionary biologist, who regarded the notion as a profound heresy against Charles Darwin’s theory of natural selection anchored in the thesis of survival of the fittest.

Gaia was an instant inspiration for the green movement; but it took years to get overt recognition from the scientific establishment. That came in 1988 when the American Geophysical Union held a meeting in San Diego, California, that drew leading physicists, biologists and climatologists to weigh the evidence for Gaia and debate its implications for the future of science.

In 2001, more than 1,000 scientists met in Amsterdam to declare that the planet “behaves as a single self-regulating system comprised of physical, chemical, biological and human components”. In effect, Lovelock and Margulis had won the day: the details could be debated, but the broad argument was settled.

Early in his career, Lovelock devised techniques to freeze and then re-animate cell tissue, and even whole animals such as hamsters. Just for fun, in 1954, he used microwave radiation from a continuous wave magnetron to cook a potato. “It may have been the first working microwave oven used to cook food that was then eaten,” he wrote. “If it was, then I did invent it.”

He worked with the actors Leo McKern and Joan Greenwood on a BBC drama, The Critical Point (1957), about the experimental freezing of a human, and used a home-made electronic sound generator to simulate the failing breath, the fading heartbeat and the death rattle of an actor. He was later told that his tape inspired the BBC to found its pioneering radiophonic workshop.

He designed new types of extraordinarily sensitive instruments that could detect the presence of unimaginably tiny concentrations of man-made chemicals in gases. When they were used to study the chemistry of the atmosphere they pointed the finger at the spread of chlorofluorocarbons (CFCs) as the source of destruction of the ozone layer. Similarly, they revealed the accumulation of residues of pesticides in the tissues of virtually all living creatures, from penguins in Antarctica to mothers’ milk in Europe and the US.

Throughout his life he went on delivering inventive ideas. With Chris Rapley, then director of the Science Museum in London, Lovelock proposed in the journal Nature in 2007 a way by which humans could churn the world’s oceans to stimulate algal growth, draw down extra carbon dioxide from the atmosphere, increase the formation of sunlight-reflecting clouds and thus damp down global heating.

Lovelock was born in Letchworth Garden City, Hertfordshire, but was brought up in Brixton, south London, where his parents, Tom and Nellie, ran a shop selling picture frames. He was educated at the local grammar, the Strand school. At an early age, he discovered the public library, which he said fired a fascination with science. By comparison, he found science lessons at school dull.

In the unfettered freedom of the library, he soaked up information with equal relish from science fiction or any science textbook that caught his interest, on astronomy, natural history, biology, physics and chemistry. Lovelock’s practical flair was also given free rein. He recalled inventing a gadget as a schoolboy, an airspeed indicator that he held out of the window during train journeys.

His parents could not support their son at university, so Lovelock got a job as a laboratory technician in industry, and studied for a BSc at evening classes. In 1940 he joined the National Institute for Medical Research at Mill Hill, where he stayed for 20 years. Then a Quaker, he was a conscientious objector during the second world war.

While at the NIMR, he took a PhD in biomedical science and made the most important of his inventions, the electron capture detector. It was a matchbox size device that could detect and measure tiny traces of toxic chemicals. Like many great inventors Lovelock was not really a team player. He craved independence. The electron capture detector earned him enough money to get that freedom, and in later years he liked to describe himself as an “independent scientist since 1964”.

“Any artist or novelist would understand,” he wrote in his autobiography, Homage to Gaia (2000), “some of us do not produce their best when directed.”

Lovelock’s transition to independence began when he left the NIMR in 1961 to work for Nasa, the US space agency. He was invited to design experiments for the Surveyor series of unmanned spacecraft that were to examine the surface of the moon before the US government would authorise a lunar landing attempt by the Apollo astronauts.

He moved from the moon project to work with Nasa’s interplanetary exploration team at the Jet Propulsion Laboratory (JPL), Pasadena, California, on ideas for looking for signs of life on Mars. He was surprised at the shortage of suggestions from the universities and research institutes to a request from Nasa for proposals to study the biological aspects of the Red Planet.

He attributed the lack of interest to an obsession with molecular biology and genetic evolution triggered by the stunning discovery by Francis Crick and James Watson of how the genetic code was carried by DNA. Lovelock was disappointed in the shift in the focus of research in biology from the big picture to the small. The study of life concentrated more on a closer examination of molecules and atoms rather than on whole organisms, with the implication that the whole was never more than the sum of its parts and scientists could figure out how organisms worked by taking them to pieces.

Lovelock’s experiments to look for signs of life on Mars were conceived quite differently, through a holistic approach rather than a reductionist one; and his approach had an important influence in the thinking he and Margulis shared in establishing the principles of the Gaia theory.

Nasa plans to look for evidence of extraterrestrial life were targeted initially on Earth’s neighbouring planets, Venus and Mars. Lovelock predicted from a study of the chemical composition of their atmospheres that both Mars and Venus would be lifeless. Then, with a bit of pure lateral thinking, he wondered how Earth might appear to an extraterrestrial intelligence.

He pursued the idea in a conversation with Dian Hitchcock, a colleague at JPL, about why there were such extreme differences between the atmosphere of Earth and those of Mars and Venus. He said the conclusion he reached was probably the moment Gaia was born.

The atmospheres of both Mars and Venus comprised over 95% carbon dioxide, with small amounts of nitrogen, oxygen and other gases. In contrast, the Earth’s atmosphere was 77% nitrogen and 21% oxygen, with traces of carbon dioxide and other gases. He looked for an explanation as to what made the Earth’s atmosphere so different, and unique in our solar system. The evidence that the sun’s energy had increased 30% during the three and a half billion years life had existed on the planet, and yet the Earth’s surface temperature had remained constant, particularly puzzled him.

Lovelock reckoned that, according to standard physics, the planet’s surface should have boiled with the increasing heat, rather than remain cool. The only explanation, he decided, was that the Earth was a self-regulating system that had found a way to preserve its equilibrium: and that the organisms on Earth had kept their environment stable. He reasoned that the Earth’s atmosphere was a continually changing balance of gases because of its living and breathing inhabitants, while the Martian atmosphere was static.

The regulatory mechanism began when the earliest life-forms in the ancient oceans extracted carbon dioxide from the atmosphere and released oxygen back into it. Over vast spans of geological time, the concentration of carbon dioxide in the Earth’s atmosphere declined to the present composition to favour the oxygen-dependent organisms. Lovelock and Margulis argued that the biosphere of planet Earth could be considered a self-evolving and self-regulating system that unconsciously and subtly manipulated atmosphere, water and rocks to its own advantage.

When he was developing his theory, Lovelock described his ideas to his then friend and neighbour in the Wiltshire village of Bowerchalke, the novelist William Golding, and asked his advice on a suitable name. Golding suggested Gaia, after the Greek goddess who drew the living world forth from Chaos.

As an illustration of the Gaia theory, Lovelock invented the Daisyworld model of coevolution. Daisyworld involved a field of black and white daisies. If the temperature rose, the black flowers absorbed more heat than the white ones, and withered. The white daisies proliferated. Eventually, the white daisies reflected more heat back into space, cooling the planet down again and allowed the black daisies to re-emerge.

Although Gaia exerted a great influence on the green movement, Lovelock had, by his own admission, “never been wholly on the side of environmentalism”. He acted as a consultant to corporate groups such as Hewlett-Packard and Shell, and in Homage to Gaia wrote: “Too many greens are not just ignorant of science, they hate science.” He likened them to “some global over-anxious mother figure who is so concerned about small risks that she ignores the real dangers”. He wished they “would grow up” and focus on the real problem: “How can we feed, house and clothe the abundant human race without destroying the habitats of other creatures?”

Unlike most environmentalists, Lovelock favoured nuclear energy. “Some time in the next century, when the adverse effects of climate change begin to bite, people will look back in anger at those who now so foolishly continue to pollute by burning fossil fuel instead of accepting the beneficence of nuclear power. Is our distrust of nuclear power and genetically modified food soundly based?” he asked.

He filed more than 40 patents, and wrote more than 200 scientific papers, as well as several books on the Gaia theory. He was awarded scientific medals, and showered with international prizes and honorary doctorates by British and other universities.

From his first book, Gaia: A New Look at Life on Earth (1979), to his last, published when he was 99, Lovelock wrote elegantly and persuasively. He remained an optimist. In Novacene: The Coming Age of Hyperintelligence (2019), he delivered what he called “a shout of joy” for the colossal expansion of human knowledge during his lifetime, and hoped for the potential salvation of humanity by a new generation of artificially intelligent cyborgs that would – unlike many of his fellow humans – understand the importance of other living things in maintaining a habitable planet.

In 1977, Lovelock and his wife Helen – already ill with multiple sclerosis – moved from Bowerchalke to Coombe Mill, near the Devon/Cornwall border, which grew into a 35-acre woodland experimental farm. In later years he lived in Abbotsbury, near the Dorset coast.

Helen (nee Hyslop), whom he had married in 1942, died in 1989. His second wife, Sandy (nee Orchard), whom he married in 1991, survives him, along with two sons, Andrew and John, and two daughters, Jane and Christine, from his first marriage.


The climate disaster is here, with temperatures soaring across Europe, the US and much of the northern hemisphere – and scorching summers becoming the norm. As scientific predictions become reality, the emergency is becoming palpable, indisputable and widespread, with dramatic weather events reported with an ever-increasing frequency. Such patterns have disastrous, far-reaching effects –for the natural world, global food supplies, health, infrastructure and more. 

UN chief António Guterres has likened the crisis to ''collective suicide". The Guardian is one group of people who are trying to avert such a scenario, with daily reporting on the emergency. We are calling on you to support us, to ensure that even more people are made aware of the dangers — and opportunities — of this moment.

3597. Marxism, Science, and Science Studies: Marx and Engels to COVID-19 and COP26

By Helena Sheehan, Monthly Review, May 1, 2022

The history of Marxism in relation to science is extraordinarily dense and dramatic. Although it is a fascinating and important story, it is one increasingly forgotten.

From the beginning, Marxism took science extremely seriously, not only for its economic promise in building a socialist society, but also for its revelatory power in understanding the world. Marxism has made the strongest claims of any intellectual tradition before or since about the sociohistorical character of science, yet always affirmed its cognitive validity.

Science was seen as inextricably enmeshed with economic systems, technological developments, political movements, philosophical theories, cultural trends, ethical norms, ideological positions—indeed, all that is human. It was also a path of access to the natural world, generating studies, texts, theories, tensions, and debates.1 The objectivist/constructivist dichotomy could never capture this epistemological dynamic. Nor could internalist/externalist dualism ever do justice to the interacting field of forces harnessed in its historiographical process.

Karl Marx and Frederick Engels were acutely attuned to the science of their times and integrated their awareness into the core of their thought process in developing the intellectual tradition and political movement that came to be called Marxism. I would prefer that this complex theoretical and political history not be named after one man, but so it was.

There have been controversies about the Marx-Engels relationship, with a tendency to counterpose a humanist Marx to a positivist Engels, especially to dissociate Marx from Engels’s posthumous Dialectics of Nature. The dialectics of nature debate resurfaces periodically, as it has done recently, and there is a stronger tendency to vindicate Engels today than when I entered the fray decades ago.2 What is at stake is the development of a comprehensive worldview embracing both human society and the natural world, with a strong emphasis on cutting-edge science.

The subsequent generation of Marxists, during the period of the Second International, also paid acute attention to the onward development of science and there were debates about its implications and consequences, especially in response to trends such as positivism, Machism, and neo-Kantianism.

After the Russian October Revolution, there was an intensification of this activity. Science was a necessity in building a new social order. Scientific theory was thought to be not only a matter of truth and error, but also of life and death. There were many debates, including between those more grounded in the empirical sciences and those who stressed the continuity of Marxism with the history of philosophy.

Intertwined with all the intellectual debates of the day was an intense struggle for power. There was tension with a more cosmopolitan Marxist intelligentsia, who had found their way to Marxism in difficult and dangerous conditions, exposed to an array of intellectual influences, accustomed to mixing with intellectuals of many points of view and arguing the case for Marxism in such milieus. They came under increasing pressure from those who had come up under the revolution, never been abroad, knew no foreign languages, had little detailed knowledge of either the natural sciences or the history of philosophy, and never mixed with exponents of other intellectual traditions. Some were more inclined to cite the authority of classic texts or party decrees than to engage in theoretical debate. They were being fast-tracked in their careers and taking over as professors, directors of institutes, and members of editorial boards, occupying positions of authority over intellectuals of international reputation. There was high drama and, soon, blood on the floor.

It was the more cosmopolitan intelligentsia that came to London in 1931 for what is perhaps the most memorialized conference ever. The Second International Congress on the History of Science and Technology spilled over into the mass media with the arrival of a Soviet delegation led by Nikolai Bukharin and including Boris Hessen, Nikolai Vavilov, and others renowned in the history of science. They were struggling for their version of Marxism against one set of pressures at home and quite another abroad. They navigated these turbulent waters impressively. Nevertheless, tragedy engulfed them. Bukharin, Hessen, and Vavilov all perished in the purges.

The paper from this congress that had the greatest impact then and since was Hessen’s “The Social and Economic Roots of Newton’s Principia,” often cited as a classical manifesto of the externalist position in the historiography of science. Hessen examined the roots of Isaac Newton’s thought within the social, political, and economic forces of his time, seeing Newton as a son of seventeenth-century mercantile capitalism and the class compromise of 1688, combining mechanistic causation with theological speculation in his pattern of scientific explanation. Within the Soviet Union, Hessen was defending relativity theory and quantum mechanics against a position that argued that the new physics was rooted in bourgeois idealism. Although he emphasized the socioeconomic roots in London and cognitive credibility in Moscow, most provocatively in both contexts, against conflicting pressures, his position was a consistent one, demonstrating a dialectical synthesis of internal and external factors, empirical evidence, logical argument, and socioeconomic context. Hessen was not an externalist.3

Bukharin was a major figure in both the political and philosophical development of Marxism. Although a possible successor to V. I. Lenin, he had fallen from the pinnacle of power, yet was still a prominent player in many sectors of Soviet life, from the arts and sciences to economic planning. In the pressure to “Bolshevize” every social institution and academic discipline, to shut down debate and arrive at a correct Marxist line on every question, Bukharin stood up to brash Bolshevizers who were attempting to override the process of scientific discovery, siding with geneticists such as Vavilov against Trofim Lysenko. In London, Bukharin set out to convey the intellectual vitality of Marxism to a skeptical audience, placing Marxism within the context of all contemporary currents in philosophy. He continued refining his philosophical position throughout the decade. Even in his prison cell, preparing to leave life, he wrote a major tract on philosophy that showed a most impressive grasp of the history of philosophy as well as philosophical problems within science.4

The 1931 congress brought forces already in motion into a new level of interaction with each other. At the congress, contrasting worldviews collided. Those most touched by this confrontation were those who stood in between, the left-wing scientists in Britain who shared the visitors’ vision from afar. The ideas of J. D. Bernal, J. B. S. Haldane, and other leading scientists who became Marxists took hold among many of their contemporaries and gave rise to a dynamic radical science movement in the 1930s.5

This encounter between British and Soviet Marxists radiated outward and touched many who did not attend the congress. The book Science at the Crossroads, collecting the Soviet papers from the congress, was translated into many languages and found its way into many parts of the world for decades. It was read by Antonio Gramsci in his prison cell and by Christopher Caudwell as he raced through every field of human knowledge, reconceptualizing all from a Marxist point of view. From this, Caudwell produced many amazing tracts on biology and physics, as well as history, philosophy, psychology, and culture—all left unfinished when he was killed in the Spanish Civil War.

Caudwell showed how scientific discoveries reflected fresh contact with the natural world through empirical experiment but received their form and pressure from the social relations of the age. He argued that the problems of physics could not be solved within physics alone and saw the metaphysics of physics as rife with the same dualisms as every other aspect of bourgeois consciousness. Caudwell saw knowledge as advancing at an empirical level while generating confusion and chaos, as bourgeois culture was unable to assimilate its achievements or unleashed forces because of the lack of an integrated worldview.6 Bernal too saw Marxism as providing such an integrated framework. It was a philosophy derived from science that brought order and perspective to science and illuminated its onward path. It provided a method of coordinating the experimental results of science and unifying its different branches in deep sociohistorical perspective. He called for a science of science—what later came to be called science studies.7

Marxists of this period not only elaborated this position, but also entered into polemics with others holding contrary views. In philosophy of science, arguments against James Jeans and Arthur Eddington, who were seen as importing irrationalism into science itself, were particularly prominent. It is not hard to know what Marxist scientists and philosophers of science of that time would make of the postmodernist anti-science science studies that came later.

After 1945, the influence of Marxism spread ever wider. In Eastern Europe, Marxism became the dominant force in the universities, research institutes, and academic journals of new socialist states. It spread to Asia, Latin America, and Africa in liberation movements, some of which became parties of power. Marxism was sometimes a matter of deepest conviction, but sometimes not. Being an orthodoxy in a one-party state was not a recipe for the healthy development of an intellectual tradition.

Nevertheless, there was serious work done in developing a distinctive approach to science, particularly in exploring the philosophical implications of the natural sciences. This was the case in the academies of Eastern Europe, in the intellectual life of Communist parties, in journals such as Science & SocietyLa PenséeModern Quarterly, and Monthly Review. It was very different from the narrowly methodological approach being pursued in philosophy of science elsewhere. It was work of profound significance that was too little known outside these milieus.

Marxism combined attention to the advancing results of the empirical sciences with the development of a philosophical framework capable of integrating expanding knowledge and an awareness of the sociohistorical context of it all.

In the rest of the world where capitalism held sway, the 1960s and ’70s put Marxism on the agenda in a new way. New left ferment pervaded North America and Western Europe especially. This was a time when all that had been assumed was opened to question, when the universities and the streets became contested terrain. Academic disciplines were scrutinized at their very foundations. Philosophy, sociology, literature, science—all knowledge—was seen as tied to power. University campuses and academic conferences were alive with passion and polemic. Journals such as Radical PhilosophyInsurgent SociologistScience for the PeopleRadical Science Journal, and Science as Culture gave expression to this ferment. Many of my generation threw ourselves wholeheartedly into this searching, this striving. We burned many boats and set ourselves swimming in strange seas. Never in my youth as a little Catholic cold warrior did I imagine myself crossing to the other side of the “iron curtain” and becoming a communist. Even when I first moved to the left, I did not see myself as heading that way.

There was residual anticommunism as well as generational rebellion in the U.S. new left’s attitude to the old left. There was also a naiveté about power, obliviousness of economics, and suspicion of science. I shared these attitudes at first. I changed when I moved from the United States to Europe, where the gap between new left and old left was not so wide. My involvement in the political culture of Europe was transforming and I took a new look at the previous generation of the left. Although many were still alive, those who touched me most deeply were dead. Nevertheless, they came to life again in my imagination as I read their texts and grilled their contemporaries about their lives. Bernal and Caudwell especially were my mentors. Perhaps it had something to do with the sensibility of Catholics who become communists.

I was interested in Marxism as a comprehensive worldview. I was intrigued by the ways in which intellectual movements were rooted in sociohistorical forces. I saw the whole history of philosophy that I had been studying in a new way. I saw everything in a new way, a way in which everything was interconnected: philosophy, culture, politics, economics, science. I decided to focus on science within this network of relationships. Researching my book Marxism and the Philosophy of Science: A Critical History was an absorbing adventure, especially during my intervals in Eastern Europe. I felt like a detective uncovering an intricate series of intersecting stories. I tried to write a Marxist history of Marxism and science, despite the enormous and opposite pressures on me as I strove to do so—pressures from east and west, left and right, old and new left, commitment and career.

Sometimes, to my surprise, I felt more of an affinity with the previous generation than my own. I could not understand why my contemporaries, especially among British Marxists, turned their backs on the earlier generation of British Marxists and went flocking to Louis Althusser or Michel Foucault. New Left Review veered between obliviousness and hostility to the previous generation of British Marxists. Marxism Today moved ever further from Marxism, no matter how far the term was stretched.

Radical Science Journal did engage with the earlier generation, however critically. Gary Werskey’s book The Visible College was perhaps the most substantial work mediating between these generations on the question of science. Robert Young’s “Science Is Social Relations” was the most explicit and provocative exposition of a new left position on science. Reacting strongly against the view that science itself is neutral and that only the use or abuse of science is ideological, Young and Radical Science Journal held that science as such is ideological. We never encounter nature unmediated, the argument went, and so what we call nature is socially negotiated and socially constructed, a product of interactions among contending interests. From the premise that modern science, with its characteristic concepts of truth and rationality, and modern capitalism, with its alienating division of labor, arose upon a single edifice, came the conclusion that both would have to be totally dismantled. For Young, science meant capitalist science, epistemology was a bourgeois pursuit, and philosophy of science was a dead end. It was hard to see a way forward. It was a far cry from the affirmation of science characterizing previous generations of the left.8

Meanwhile, some of us carried on in the tradition of older generations of the left, most outstandingly Richard Levins and Richard Lewontin, who brought it to bear on the advancing science of our times, always clear that “the truth is the whole,” especially in polemics against trends that got lost in the parts.9

Through the 1970s, I found what was going on within the intellectual culture of the left to be much more absorbing than anything at Trinity College Dublin, where I was based at the time. Every summer I went over to the Communist University of London. There were alternative approaches to every academic discipline and the liveliest debates imaginable. I veered to the courses on philosophy, history, science, Soviet studies, gender studies, but regretted that I could not attend the ones on psychology, anthropology, literature, and other fields.

Living as if in some parallel universe much of the time, parts of academe proceeded as if the only story in philosophy of science was the one proceeding from the Vienna Circle through Karl Popper, Imre Lakatos, and Thomas Kuhn. Philosophy of science in philosophy departments rarely took a sideways glance at this other tradition. I found adjusting to the philosophy department at Trinity strange every time I returned from Moscow, Berlin, Dubrovnik, or even London.

Meanwhile, Soviet delegations were no longer a surprise at international conferences. They were integrated into the organizing structures and gave papers in many sessions. How much of a meeting of minds occurred, however, was another matter. The World Congress of Philosophy was to be held in Düsseldorf in August 1978. I spent much of that year in Eastern Europe, mostly in Moscow. The philosophers there were constantly talking about it. In fact, they were preparing for it as if for Warsaw Pact maneuvers. They kept asking me what Irish and British philosophers were planning. They were not planning anything in the sense that they meant. They were coming or not coming as individuals and thinking only about their own papers and travel arrangements.

At the congress itself, philosophers from the socialist countries and philosophers from the rest of the world mostly read papers past each other (as most academics at most congresses do). There were, however, several skirmishes and a Cold War atmosphere. I felt myself to be in a similar situation to that of British Marxists at the 1931 congress. I moved between both sides in a way that very few did. I found this quite stimulating and entered into all of the polemical possibilities the situation offered.

It was similar at other conferences in those years, for example, the 1979 International Congress of Logic, Methodology, and Philosophy of Science in Hanover and the 1981 International History of Science Congress in Bucharest. At the latter, I was often in the company of British historians of science. I felt that my arguments that Marxism plus science did not necessarily equal Lysenko were constantly undermined by the locus and events of the congress. Elena Ceausescu was presented to a plenary session as a great scientist and many sessions featured Romanians arguing that Romanians were responsible for many discoveries in the history of science and technology attributed to others, including Albert Einstein. There were others who were negotiating these tensions. Joseph Needham, present at the 1931 congress and prominent in the movement of left scientists in the 1930s, was there still mediating between east and west fifty years later.

There were other enclaves where there was sustained cross-fertilization, such as the Boston Colloquium in Philosophy of Science, issuing many volumes of Boston Studies in the Philosophy of Science, edited by Robert Cohen and Marx Wartofsky. The Inter-University Centre in Dubrovnik was a pioneering and important base for interaction between east and west, between Marxists and non-Marxists. I have happy memories of stimulating encounters in these milieus. The philosophy of science conference in Dubrovnik was preoccupied with the defense of scientific realism against various forms of social constructivism, particularly the Edinburgh School and Paris School. Arguing against positions of Barry Barnes, David Bloor, and Bruno Latour were philosophers from a critical Marxist position such as Wartofsky, Srdan Lelas, and WÅ‚adisÅ‚aw Krajewski, alongside others from different philosophical traditions, such as William Newton-Smith, Rom Harre, and Ernan McMullin. The dialogue was free, friendly, funny, and purposeful.10

This was a particularly difficult time for me as a precariously employed intellectual. I often felt angry and bitter, near to despair at times, but I kept working. I lectured at many venues, from Ivy League universities to local employment centers, became a talking head on radio and television, and diversified into cultural studies. When it came to a secure position, I was always passed over for someone safer, even if less qualified. Long after I thought it would never happen, I did finally get a tenured academic position in the 1990s.

Marxism may not have been an asset to me in career advancement, but it made me develop a way of thinking through the trials and tribulations that it brought upon me. I had intellectual clarity and moral purpose and that was a lot. I had ways to steel and to console myself. I thought: Who were the prestigious professors of philosophy when Marx and Engels were writing their classic texts while living difficult exiled marginalized lives, when Caudwell and David Guest were bleeding on battlefields with all their brilliance and passion draining into the soil of Spain, when Bukharin was writing in his bleak cell, arguing the case for Marxism to posterity right up to the moment when he was taken out to be shot? So many times, I had sung “through dungeons dark and gallows grim,” but I was not imprisoned, I was not executed. I could live with unemployment, semi-employment, marginalization, condescension, injustice. I could endure the loneliness of the long-distance Marxist.

In Eastern Europe, within a few years, there was much happening. Everything opened up only to close down again. In 1990, it seemed that the world turned upside down. The Soviet Union, the German Democratic Republic, Czechoslovakia, and Yugoslavia disappeared from the map of the world. I often wondered how many of the intellectuals I met in Eastern Europe would be Marxists if there were a regime change. I found out. I had several confrontations in the 1990s with those who had made their careers professing Marxism and then made their careers denouncing it. Academic life all over the world is full of such people. They do what is necessary to advance themselves and they are rewarded, then and now, but they will never produce anything of real value.

In 1996, I was sent to a university in Slovakia, as part of the European Union’s Trans-European Mobility Programme for University Studies, which sent Western academics into Eastern universities to show them how “proper” universities were run, a blatantly colonizing project. I was asked to give a guest lecture on a topic of my choice. I picked Marxism. They were surprised, then disconcerted. Nevertheless, they organized it. The room was packed. Marxism had the frisson of forbidden fruit again. I said that the situation was ridiculous. Marxism was the philosophy for decades and then it disappeared from the curriculum, as if it had never happened. It was orthodoxy one day and apostasy the next. It was not healthy. Marxism, I argued, was a major intellectual tradition in the history of the world and things would never be healthy until it found its place vis-à-vis all contenders in the overall scheme of things. People came whispering to me in the following days, saying that they agreed.

I have returned over the years to Eastern Europe to see where all the Marxists went. I have been most impressed when visiting the vanquished, the Marxist intelligentsia who were still Marxists, especially those involved in philosophy of science, who once occupied the apex of academe and subsequently led quite marginalized lives. However, there has been much dishonesty and denial. It has extended even to the dead. I have been profoundly distressed to read obituaries of those I knew as Marxists where this was never mentioned. When I asked questions about Marxism, it was sometimes as if I were probing sexual liaisons or spy scandals. Nevertheless, while the topic still generates a considerable unease among many, what I have found most striking is the surprise of younger intellectuals at hearing someone make a case for Marxism in this area and their openness to considering it.

Loren Graham of the Massachusetts Institute of Technology and Harvard University, who has spent his whole professional life studying Soviet and post-Soviet science and philosophy of science, has testified to the lasting impact of dialectical materialism on Russian scientists, even after the demise of the Soviet state. Moreover, he observed: “This philosophy of science is actually quite a sensible one and corresponds to the implicit views of many working scientists all over the world.”11

What does Marxism have to offer to science and science studies now? These fields seem to be flourishing in the sense that there is a lot happening. There is much funding, many metrics, all sorts of empirical studies. Much of this is interesting and valuable, although a lot of it is bland and bitty. Many studies are short and shallow, driven by market demand and fast-track careerism more than intellectual quest. There is not much in the way of thinking that is simultaneously empirically grounded, philosophically integrated, and sociohistorically contextualized. This is what Marxism could bring to bear. Instead, science and science studies go from one extreme to the other: from the minutiae of molecules to the Tao of physics. It is either science stripped of philosophical and historical reflection or it is new age nonsense stepping into the philosophical gap and filling the bookshop shelves. Both are commercially successful. Contradiction sells.

The intensification of the commercialization of science, as part of the general commodification of knowledge, is the strongest force in the field today. A new orthodoxy has taken command, not so much by winning arguments, but by wielding systemic power on a global scale. Philosophy is not thriving in this arena. Nor is theory in any discipline. Universities are being harnessed to operate by market norms and survival of the fittest in commercial competition, outstripping all other forms of validation, particularly truth criteria, theoretical depth and breadth, moral responsibility, and political engagement. There are powerful pressures disincentivizing, eroding, and marginalizing critical thinking, creative thinking, and especially systemic thinking.

Universities are contested terrain. The atmosphere has changed drastically from what prevailed in the 1960s and ’70s. Then, large-scale contending paradigms in every area faced off with great energy and passion. This has dissipated. It is disconcerting, because nothing has been solved. People have learned to live with problems unresolved or unacknowledged, or to settle for resolution at a less than fundamental level. The confrontations of worldviews have given way to low-level eclecticism. There is a narrowing of perspective and a retreat from engagement, whether through myopia, ignorance, shallowness, conformity, fear, or careerism.

So much of what I read or review in so many areas is half-baked. Conceptualization is weak and confused. Contextualization is thin and random. Marxism has nurtured in me a demand for conceptualization that is strong and lucid, for contextualization that is thick and systemic. Many social studies of science are still too weak in conceptualization and contextualization.

There have been periodic rediscoveries of the sociohistorical context of science as if Marxism had never happened—from Kuhn to the Edinburgh School to Latour. This is not to deny the significant contribution of the Edinburgh School, offering an impressive output of empirical studies of intriguing episodes in the history of science connecting social structures to cosmologies, relating class interests to positions taken in scientific controversies. They have argued against seeing what is considered to be true and rational in the history of science as unproblematic, as needing no sociological explanation, and against understanding social factors as necessarily involving distortions or corruptions of science. They have taken issue with the older view of knowledge as individualist, passive, and contemplative in favor of a view of knowledge as social, active, and contextual. Knowledge is conceived as a product, not of passively perceiving individuals, but of interacting social groups. Scientific theories are not individually revealed but socially constructed. This much is in common with Marxism.

However, unlike Marxism, Edinburgh School proponents see scientific knowledge as totally contingent, leaving us with no overall patterns, no necessary connections linking knowledge either to the social order or to the natural world, no concept of scientific progress, no criteria of differential assessment. For them, social groups simply choose theories as resources to suit their purposes and there is no way in which such theories can be ranked in terms of their proximity to reality or their rationality. They constantly shift ground, veering from the most arbitrary voluntarism to the most mechanistic determinism. They set down a hard interest-constitutive model of knowledge and then plead for disinterested research. They argue against giving science a special status vis-à-vis other forms of culture and against criteria of demarcation and then give the highest honorific status to science. It is too random, too contradictory, too loose to take us any further toward a deeper insight into the relationship between the cognitive and social aspects of science.12

The science wars of the 1990s took up the threads of this tension. I found myself on both sides, yet wholly on neither. I agreed with those who wanted to defend the cognitive capacity of science against epistemological antirealism, irrationalism, mysticism, conventionalism, and especially anything-goes postmodernism. I also agreed with those who insisted on a strong sociohistorical account of science against a reassertion of scientism. A better grounding in what the Marxist tradition has brought to bear on these issues would have illuminated the terrain. I do not believe that the debunking of science in terms of its cognitive validity is an appropriate activity for the left.13 It is neither epistemologically sound nor politically progressive. The left should take its stand with science—a critically reconstructed, socially responsible science, but with the possibilities of science.

Science and science studies have tended increasingly to back away from the big ideas that were once in play. They have become too small, too introverted, too obsessed with mini debates of micro-tendencies, with only weak evidence of relevant intellectual history and social context.14

As to philosophy, although it is central to the human condition, many professional philosophers have reduced it to technicist esoterica or obfuscating nonsense. They have alienated many who have come to it seeking meaning, putting any defense of its declining status on dubious grounds. Some texts in philosophy of science seem to me to be equivalent to obsession with a game of chess while the house is burning down around it.

Marxism is still an alternative. It is still superior to anything on the scene. It is a way of seeing the world in terms of a complex pattern of interconnecting processes where others see only disconnected and static particulars. It is a way of revealing how economic structures, political institutions, legal codes, moral norms, cultural trends, scientific theories, philosophical perspectives, even common sense, are all products of a pattern of historical development shaped by a mode of production.

Marxism as a philosophy of science is materialist in the sense of explaining the natural world in terms of natural forces and not supernatural powers. It is dialectical in the sense of being evolutionary, processive, developmental. It is radically contextual and relational in seeing everything that exists within the web of forces in which it is embedded. It is empiricist without being positivist or reductionist; rationalist without being idealist; coherent and comprehensive while empirically grounded.

It needs constantly to be revised in light of the most advanced science, the most up-to-date knowledge, of its time. In philosophy of science, this means reflecting substantively on the philosophical implications of the empirical sciences and doing so in a thick sociohistorical context. In philosophy, generally it means looking to other disciplines and to interdisciplinary inquiries and participating in debates about the theoretical foundations of growing knowledge. It means scrutinizing contemporary shifts in the very production of knowledge.

Marxism has been a major position in the history of philosophy. It has been a formative force in science studies and other disciplines, and it is a continuing influence. It is not as influential as it deserves to be in the current intellectual landscape, but it is still more influential than many might think. It is there in ways that are not always acknowledged. It is sometimes the philosophy “that dare not speak its name.” Moreover, many of its premises have come to be so accepted that it seems no longer necessary or opportune even to know from where they have come.

Marxism lives on, but in circuitous and complex ways, sometimes in strong, brilliant, defiant ways, sometimes in subtle yet influential ways, but sometimes too in weak, confused, and debased ways. It is often “Marxism lite” as an element of shallow intellectual history to be raided for random insights for shallow theory. Some are quasi-Marxists or post-Marxists. They have become discouraged by defeat or decentered by postmodernism. It was one thing when the wind was at their back, but they have been swept off their feet by crosswinds they could not withstand. There are ebbs and flows and new waves of realization all the time.

The current push for the decolonization of knowledge is important. I cheered as Rhodes fell at the University of Cape Town in 2015. I cringed every time I passed it on campus prior to that. However, I have watched as a lot of this progressive impulse has become unmoored for failure to see what has been achieved by previous generations or that the central force colonizing knowledge is capital. I am already seeing a lot of it co-opted into a bland and blind liberal agenda.15

There is evidence of a revival of interest in Marxism in relation to science now. Over the years, my invitations to speak about it rose and fell. The reasons why I and other Marxists are now sought out have more to do with our current planetary emergency, particularly the looming climate catastrophe and the persisting COVID-19 pandemic. Science has become urgent. Premodern or postmodern antiscience is a blind alley. Positivist scientism has some limited potency, but is too narrow, too myopic to grasp the full picture.

I have not seen much of the postmodernist critique of science lately. Because science has become so salient, so immediate, so crucial to our collective fate, I do not think anyone wants to hear that we have no criteria for deciding between contending truth claims or that science is inherently deceptive or oppressive. Yet science under capitalism has never been so problematic. Only systemic analysis can address this, and only action flowing from this understanding is able to deal with the issues that emerge.

The statistics on carbon emissions or biodiversity loss only get us so far unless we name the system that created the problem, fuels the process, and blocks possible solutions. There is so much being written about ecological crisis, but it is Marxists, such as John Bellamy Foster, Ian Angus, and Andreas Malm, who connect the science to philosophy, sociology, and political economy, who bring the whole picture into clear focus and point the way beyond it.16

It is the same with the current pandemic. The statistics on COVID cases, hospitalizations, deaths, vaccinations, and mitigation measures only get us so far unless we see what conditions have created this pandemic and persist to create future and fiercer pandemics. It is Marxists, such as Mike Davis and Rob Wallace, who predicted that such a pandemic was coming and showed how it was bound up with circuits of capital. Whatever may have happened in the Wuhan lab or market, the real source is in deforestation, destruction of habitats, wildlife trafficking, the whole industrialized system of food production, and the global circuitry of capital. Marxists and others have highlighted the downgrading of public health systems, the negative effect on patents, and the stranglehold of big pharma in obstructing just distribution of vaccines and therapeutic medicines.17

We need a more open, cooperative international science to deal with these problems. There have been moves in this direction in response to current crises, but the obstructions are still formidable.

Marxists have been at the fore in doing the systemic thinking demanded by these crises, not only in clarifying the causes, but pointing to the solutions—solutions difficult to achieve, because the imperatives generated by ecological and epidemiological crises go contrary to the very logic of capitalism. I think this is being understood by more and more people, the sort of people who gathered outside the barriers of the 2021 UN Climate Change Conference or followed the news reports with dismay.

So where are we now? It is a paradox: never has there been such a totalizing, systematizing force as contemporary global capitalism and yet never has there been such inhibition of synthesizing systemic thinking. The centralizing market decenters the psyche. It organizes production and consumption, but disorganizes community. Nevertheless, there is a seeking of truth, a striving for justice that the system can neither satisfy nor suppress. In this, I place my hope in a revival of the kind of totalizing thinking and collective acting that Marxism has nurtured through the decades.

The history of Marxism and its relation to science is tied inextricably to the history of everything else. It has been so far a riveting drama, full of revelation, catharsis, tragedy, and farce. We are ready for the next act. It is still the unsurpassed philosophy of our time.
