Darwin and materialist science

By Ian Angus

Socialist Voice -- February 12, 2009 is Darwin Day, the 200th anniversary of the birth of Charles Darwin. His masterwork, On the Origin of Species, was published 150 years ago, in November 1859, initiating a revolution in science that continues to this day.

Although Darwin’s political views were far from radical, his insights became the central weapons in the battle to establish materialist science as the basis for our understanding of the world, and contributed to the development of Marxism.

Charles Robert Darwin was, to say the least, an unlikely revolutionary. His father was a prominent physician and wealthy investor; his grandfather was Josiah Wedgwood, founder of one of the largest manufacturing companies in Europe. He could have lived a life of leisure — instead he devoted his life to science.

After graduating from Cambridge in 1831, 22-year-old Charles Darwin boarded the British survey ship HMS Beagle as an unpaid naturalist, subsidised by his doting father. When he returned after five years, he had thousands of pages of scientific observations, over 1500 carefully preserved specimens — and growing doubts about the dominant scientific and religious ideas of his day.

A heretical conclusion

At that time, Darwin wrote in his 1861 introduction to Origin, “the great majority of naturalists believed that species were immutable productions, and had been separately created”. Biblical literalists and deists alike agreed that species were fixed by divine law. Dogs might vary in appearance, but dogs don’t give birth to cats.

After five years of travel and two years of study at home, Darwin came to a heretical conclusion: species were not immutable. All animals were descended from common ancestors, different species resulted from gradual changes over millions of years, and God had nothing to do with it.

It is difficult today to understand how shocking this idea would be to the middle and upper classes of Darwin’s time. Religion wasn’t just the “opium of the masses”— it gave the wealthy moral justification for their privileged lives in a world of constant change and gross inequality. The world was unfolding according to God’s wishes, and anyone who questioned that endangered the very fragile social order.

Nevertheless, by the 1830s educated people knew that the Genesis creation story couldn’t be literally true. The rise of capitalism in the 1700s had led to booms in mining and canal building: those works exposed geological layers and ancient fossils that clearly contradicted the idea of a recently-created earth.

In the same period, imperialism led to global exploration and the discovery of more varieties of plant and animal life than any European had ever imagined. Why had the Creator been so extravagant? And why, if each animal was created separately, were their underlying structures so similar — why do bats’ wings, whales’ flippers, lions’ paws and human hands all contain the same bones?

Many attempts were made to preserve a central role for God and creation in the face of this evidence. Perhaps the most sophisticated was developed in the 1850s by Richard Owen, head of natural science at the British Museum and inventor of the word “dinosaur”. He argued that all animals are variations on ideas — “archetypes” — in God’s mind. God “foreknew all variations” on those archetypes and made them real in forms that would suit various environments or situations over time.

At the opposite end of the philosophical spectrum, the great French biologist Jean-Baptiste Lamarck offered a non-religious explanation. He proposed that there is a “chain of being”, a ladder of life, with single-celled animals at the bottom and humans at the top. Nature constantly and spontaneously creates new creatures that have an innate drive to climb the ladder, becoming more complex, or perfect, over time.

As they climb, they also adapt to environmental changes: giraffes have long necks because their ancestors had to stretch to reach high leaves, while fish that live in caves are blind because their ancestors’ vision declined as a result of disuse. This concept was not central to Lamarck’s theory, but “inheritance of acquired characteristics” has since become inextricably connected to his name.

A materialist explanation

While Lamarck and others just speculated that species changed over time, Darwin provided convincing evidence. More important, he showed that it happened by natural processes, without any help from gods or mysterious progressive forces. That is, his explanation of evolution was materialist.

In Darwin’s theory, three factors combine to create new species: variation, inheritance and natural selection. There are many differences between the members of any species, and those differences will result in some individuals being more likely to survive environmental changes and so pass on their variations to the next generation. Over long periods of time, such variations will spread through the population, while any that reduce the possibility of reproduction will decline. Eventually the accumulation of new characteristics results in new species.

Darwin developed the key elements of his theory by 1838, but didn’t publish it because he knew how hostile the scientific community of his day was to both materialism and evolution. Only after 20 years, when he had become one of the best-known and most respected naturalists in England, did he finally make his heresy public.

On the Origin of Species was an instant best seller. The publisher printed 1250 copies but received orders for 1500 copies on the first day. A second edition of 3000 copies followed in a few weeks, and some 110,000 copies were sold in England by the end of the century.

While Darwin’s ideas were quickly accepted by many scientists, especially younger ones, they were roundly condemned by the scientific establishment and by religious leaders. Adam Sedgwick, Darwin’s geology professor at Cambridge, called On the Origin of Species “utterly false and grievously mischievous” and declared his “detestation of the theory, because of its unflinching materialism”, while Richard Owen denounced it as an “abuse of science.”

Marx and Engels and Darwin

Outside official scientific circles, Darwin’s ideas found strong support in the workers' movement. Friedrich Engels said Origin was “absolutely splendid”, and Karl Marx called it “the book which contains the basis in natural history for our view”.

Marx’s friend Wilhelm Liebknecht later recalled that “when Darwin drew the conclusions from his research work and brought them to the knowledge of the public, we spoke of nothing else for months but Darwin and the enormous significance of his scientific discoveries”.

In Origin, Marx and Engels found a materialist explanation of nature’s history to complement and strengthen their materialist explanation of human history. They particularly valued Darwin’s demonstration that nature has a history that can be explained in materialist, natural terms. In Anti-Dühring, Engels wrote:

“Nature works dialectically and not metaphysically … she does not move in the eternal oneness of a perpetually recurring circle, but goes through a real historical evolution. In this connection, Darwin must be named before all others. He dealt the metaphysical conception of Nature the heaviest blow by his proof that all organic beings, plants, animals, and man himself, are the products of a process of evolution going on through millions of years.”

A triumph for humanity

Darwin spent most of the rest of his life researching evolution and natural selection, while his supporters defended his ideas against the most influential opinion leaders of his day. By the time he died in 1882, few scientists still disputed the fact of evolution—but it took much longer for most to accept the materialist core of Darwin’s work, that variation and natural selection are the processes that drive evolution. For decades scientists searched for an alternative to natural selection that would be compatible with the idealist conception that God, or some equivalent progressive tendency in nature, guided evolution upwards until humans emerged as the pinnacle of creation.

But twentieth-century genetic research proved that Darwin was right all along: that variations occur naturally, and that natural selection is the main force determining which variations survive and spread.

Darwin’s commitment to naturalist science has triumphed. No modern scientist, not even one with deep religious convictions, would today suggest that “then a miracle happened” is an acceptable explanation for anything in nature, including the origins, immense variety and constant changes in life on our planet.

This materialist victory in science is one of humanity’s greatest achievements. For that reason alone, no matter what his hesitations, delays or prejudices, Charles Darwin deserves to be remembered and honoured by everyone who looks forward to the ending of superstition and ignorance in all aspects of life.

The idea that nature has a history, that species come into existence, change and disappear through natural processes, is just as revolutionary, and just as important to socialist thought, as the idea that capitalism isn’t eternal but came into being at a given time and will one day disappear from the earth.

Darwin the reluctant revolutionary

By Ian Angus

Socialist Resistance -- In 1846, Karl Marx and Friedrich Engels wrote The German Ideology, the first mature statement of what became known as historical materialism. This passage was on the second page: “We know only a single science, the science of history. One can look at history from two sides and divide it into the history of nature and the history of men. The two sides are, however, inseparable; the history of nature and the history of men are dependent on each other so long as men exist. The history of nature, called natural science, does not concern us here...”

At the last minute, they deleted that paragraph from the final draft, deciding not even to mention a subject they had no time to investigate and discuss properly.

What the founders of scientific socialism couldn’t have known was that a compelling materialist explanation of the history of nature had already been written by an English gentleman who had no sympathy for socialism. They couldn’t read that account, because the author, Charles Darwin, was so shocked by the implications of his own ideas that he kept them secret for twenty years.

Darwin’s views on evolution were fully developed by 1838, and he wrote, then hid away, a 50,000-word essay on the subject in 1844. But he didn’t publish what Marx was to call his “epoch-making work” until 1859.

Darwin’s insight

Others had speculated about evolution before Charles Darwin, but the dominant view in scientific circles and society at large was that all the different types of plants and animals were created by God, and that the various species were forever fixed. The few who believed that species had changed over time couldn’t explain those changes without resort to the supernatural — that evolution was God’s long-term plan, or that some force (God by another name) caused nature to strive towards perfection.

What made Darwin’s work unique was not his assertion that evolution was a fact, but his entirely materialist explanation of how all of life’s wonderful variations and designs had come to be. He argued that the main factor in evolution is “natural selection”, a process that can be summarised simply.

1. All organisms produce more offspring than can possibly survive.

2. There are many differences between the individual members of any species.

3. Variations that increase individuals’ chances of surviving to reproduce are likely to be passed on to the next generation.

4. As a result, over long periods of time, such favourable characteristics will spread through the population, while harmful characteristics will decline, so the population as a whole will increasingly be better adapted to its environment.

5. If part of the population finds itself in a different environment, it will change in different ways, and those diverging changes can eventually lead to the development of separate species.

This simple and elegant concept took the evidence most commonly used to defend creationism — the seemingly perfect design of plants and animals — and explained it by natural processes. In the words of twentieth century evolutionist Ernst Mayr, Darwin “replaced theological, or supernatural, science with secular science. … Darwin’s explanation that all things have a natural cause made the belief in a creatively superior mind quite unnecessary.”

Darwin’s delay

Darwin’s theory was entirely materialist at a time when materialism wasn’t just unpopular in respectable circles, it was considered subversive and politically dangerous. Between 1838 and 1848, while he was working out his ideas, England was swept by an unprecedented wave of mass actions, political protests and strikes. Radical ideas — materialist, atheistic ideas — were infecting the working class, leading many to expect (or fear) revolutionary change.

Darwin was never actively involved in politics, but he was a privileged member of the wealthy middle class and that class was under attack. As John Bellamy Foster writes, “Darwin was a strong believer in the bourgeois order. His science was revolutionary, but Darwin was not.”

Rather than risk being identified with the radicals, Darwin set evolution aside, and devoted the next years to writing a popular account of his voyage around the world, two scientific books on coral reefs and volcanic islands, and an exhaustive four-volume study of barnacles. Only in the mid-1850s, when his scientific reputation was assured, and the social turbulence of the 1840s was clearly over, did he return to the subject he is now most famous for.

Even then he would likely have delayed into the next decade had not a younger naturalist, Alfred Russell Wallace, sent him an essay containing ideas virtually identical to his own, in June 1858. Pressed by friends to publish first, Darwin set aside “the big book on species” he had barely begun, and quickly wrote a much shorter one — On the Origin of Species by Means of Natural Selection, or, The Preservation of Favoured Races in the Struggle for Life. It was published in November 1859.

Brilliantly argued, and written to be understood by non-scientists, Origin was an instant best-seller. The publisher printed 1250 copies but received orders for 1500 copies on the first day. A second edition of 3000 copies followed in a few weeks, and four more editions in the next ten years: some 110,000 copies were sold in England alone by the end of the century.

While Darwin’s ideas were quickly accepted by many scientists, especially younger ones, they were roundly condemned by the scientific establishment and by religious leaders. Again and again the critics raised two related arguments: that natural selection excluded any role for God; and, that although Darwin had cautiously avoided the subject, human beings must also be products of natural selection. Both ideas were blasphemous; both would undermine the existing social order.

Even among scientists who rejected Biblical literalism and agreed with much of Darwin’s argument, there were many who insisted that God had to be part of the explanation, as the guiding force of evolution or as the divine source of the human soul and intelligence. Some used that view to defend their own reactionary and racist prejudices: for example, that God had created blacks and whites as separate species.

Working-class support

The discussion of Darwin’s book wasn’t limited to scientists and clergymen. At fifteen shillings, several days’ pay for a skilled craftsman, On the Origin of Species was too expensive to be found in many workers’ homes, but groups of radical workers in several cities took up collections to buy one copy that could be passed around.

One of Darwin’s closest collaborators, Thomas Huxley, organized a series of very well-attended public lectures on evolution for working men in London. In those talks, which were subsequently published as a popular pamphlet, Huxley had no hesitation in defending a key point Darwin only hinted at in Origin, that humans too are a product of natural selection and share common ancestors:

“there is no evidence whatever for saying that mankind sprang originally from any more than a single pair; I must say, that I cannot see any good ground whatever, or even any tenable sort of evidence, for believing that there is more than one species of Man.”

Karl Marx attended several of Huxley’s lectures and encouraged his political associates to do likewise. His friend and comrade Wilhelm Liebknecht later recalled that “when Darwin drew the conclusions from his research work and brought them to the knowledge of the public, we spoke of nothing else for months but Darwin and the enormous significance of his scientific discoveries”.

Friedrich Engels obtained one of the first 1250 copies of The Origin of Species: he wrote to Marx that it was “absolutely splendid”. Marx agreed, but that did not mean that they were uncritical. They disliked Darwin’s “clumsy English style of argument”, and ridiculed his positive references to Malthus. Since they were not themselves biologists, they didn’t take sides in the highly contentious debate on whether natural selection or some other natural process was the principal driver of evolution: in his strong defence of Darwin in Anti-Duhring (1877), Engels wrote, and Darwin would surely have agreed:

“The theory of evolution itself is however still in a very early stage, and it therefore cannot be doubted that further research will greatly modify our present conceptions, including strictly Darwinian ones, of the process of the evolution of species.”

What he and Marx most admired about Darwin was his demonstration that nature has a history. Again in Anti-Duhring:

“Nature works dialectically and not metaphysically … she does not move in the eternal oneness of a perpetually recurring circle, but goes through a real historical evolution. In this connection, Darwin must be named before all others. He dealt the metaphysical conception of Nature the heaviest blow by his proof that all organic beings, plants, animals, and man himself, are the products of a process of evolution going on through millions of years.”

The insight that Marx and Engels had written and then deleted in 1846 — that the history of nature and the history of men are inseparable and dependent on one another — was confirmed by The Origin of Species. In it they found a materialist explanation of nature’s history to complement their materialist explanation of human history. Darwin’s work was, as Marx wrote in 1861, “the basis in natural history for our own view.”

A triumph for humanity

It is a testimony to Darwin’s commitment to scientific truth that, once he overcame his reluctance to publish his ideas, he devoted the rest of his life to defending them against some of the most influential opinion leaders of his day. By the time he died in 1882, the fact of evolution was almost universally accepted in the scientific community.

Subsequent research has deepened our understanding of evolution — it has also confirmed Darwin’s conviction that natural selection plays a key role. Above all, Darwin’s commitment to materialist explanations of natural phenomena has triumphed. No modern scientist, not even one with deep religious convictions, would suggest that “then a miracle happened” is an acceptable explanation for any natural phenomenon, including the origins, immense variety and constantly changing nature of life on our planet.

This materialist victory in science is one of humanity’s greatest achievements. For that reason alone, no matter what his hesitations, delays or middle class prejudices, Charles Darwin deserves to be remembered and honoured by everyone who looks forward to the ending of superstition and ignorance in all aspects of life.

The idea that “nature does not just exist, but comes into being and passes away” (Engels) is just as revolutionary, and just as important to socialist thought, as the idea that capitalism doesn’t just exist, but came into being at a given time, and it too will pass away in the future.

Suggestions for further reading.

  • The best short overview of Darwin’s life and ideas is A Brief Guide to Charles Darwin, His Life and Times, by Cyril Aydon (Constable & Robinson, 2002).
  • Chapter six of John Bellamy Foster’s Marx’s Ecology: Materialism and Nature (Monthly Review 2000) is essential reading on the relationship between Marxism and Darwinism.
  • John Bellamy Foster’s latest book, Critique of Intelligent Design: Materialism versus Creationism from Antiquity to the Present, was not yet available when I wrote this article, but having read his previous works, I have no hesitation in recommending it.
  • Ernst Mayr’s What Evolution Is (Basic Books, 2001) isn’t light reading, but it is a superb presentation of modern evolutionary theory for non-scientists.
  • Finally, Charles Darwin’s The Origin of Species may be the only great work of science that is also a work of literature. The Penguin edition includes a good introduction by historian J.W. Burrow, and is widely available.

Darwin's revolutionary ideas

February 12 is the 200th anniversary of Charles Darwin's birth. Phil Gasper explains the significance of his ideas, and why they still spark controversy today.

CHARLES DARWIN'S ideas revolutionized biology in the 19th century, but they also had a profound and lasting impact far outside narrow scientific circles, challenging religious dogmas and affecting almost every field of human knowledge.

Yet Darwin himself was a reluctant revolutionary--a man who shunned the limelight, hated controversy and became physically ill worrying that his ideas would shock Victorian England.

Darwin was a child of the rising liberal bourgeoisie. His paternal grandfather, Erasmus Darwin, was a prominent doctor and freethinker who wrote a speculative work on biological evolution in the 1790s. His mother was the daughter of Josiah Wedgwood, founder of the famous pottery.

Darwin grew up in Shropshire in England, and later attended Edinburgh University to study medicine, but soon discovered he did not have the stomach for it. He transferred to Cambridge with ideas of becoming a country parson, but instead, the botanist John Stevens Henslow ignited his interest in science.

In 1831, Henslow arranged for Darwin to join a surveying voyage on HMS Beagle as personal companion to the ship's captain, Robert FitzRoy. The voyage lasted nearly five years and was the turning point in Darwin's life.

The Beagle took him to South America, the Galapagos Islands, Tahiti, New Zealand, Australia and southern Africa, before returning to England in 1836. Darwin made detailed geological, botanical and zoological observations and accumulated a large collection of specimens. Back in England, he gained respect for his work as a geologist, including proposing a novel theory for the origin of coral reefs.

Much more radically, however, by the time of his return, Darwin had come to privately reject orthodox accounts of the origin of biological species, which viewed them as having been created in pretty much their present forms.

His observations of the similarities between living and fossil mammals, and between the distinct species of plants and animals on the Galapagos Islands and their counterparts on the South American mainland, persuaded him that biological evolution had taken place, even though he was not yet sure how.

WITHIN A few years, Darwin had elaborated his entire theory of evolution. The crucial idea is that evolution is the result of natural selection--organisms that are better adapted to their environments are more likely to survive and reproduce, thus passing on their advantageous traits to the next generation.

Although Darwin formulated his theory as early as 1837, it was to be more than 20 years before he finally made it public.

The main reason for this delay was his nervousness about the materialist implications of his views and the challenge they posed to the dogmas of orthodox religion, regarded by the upper classes as a bulwark of the status quo during a period of social unrest in early Victorian Britain.

In Darwin's account, evolutionary change was largely the result of the random, ultimately purposeless process of natural selection. This suggests a thoroughly materialist picture of the world that banishes vital forces and preordained purposes from nature, and which implies that mental phenomena emerge when matter is arranged in complex ways.

Such ideas undermine not only traditional religious views of divine creation, but also more sophisticated versions of theism, which claim that God works through evolution.

"Love of the deity effect of organization [of the brain], oh you materialist!" he wrote privately in the late 1830s. "Why is thought being a secretion of brain more wonderful than gravity a property of matter? It is our arrogance, our admiration of ourselves."

Darwin confided to his friends that going public with his ideas about evolution would be like "confessing to a murder." In 1839, Darwin married his cousin, Emma Wedgwood, who, unlike him, was devoutly religious, adding a personal dimension to this conflict.

Darwin and his wife moved to Down House in Kent, and from this period onwards, he was in poor health, probably caused at least in part by his intellectual anxieties. But Darwin's family inheritance allowed him to devote his time to science and to accumulate a mass of evidence supporting his views.

Darwin finally went public with his ideas in 1858, after learning that a young Welsh naturalist, Alfred Russel Wallace, had reached similar conclusions. The following year Darwin published his masterpiece, The Origin of Species, which makes a methodical case for evolution.

Darwin argues that natural selection is a real process, analogous to the way in which plant and animal breeders can dramatically alter the characteristics of a group of organisms over a series of generations by permitting only those with desired traits to reproduce.

In the natural world, a population of organisms can become better and better adapted to its environment over a period of time, and the characteristics of its members at the end of the process may be very different from those of their ancestors.

Darwin went on to argue that natural selection is capable of giving rise not simply to new varieties, but to new species, and that it can in principle account for all the characteristics of existing organisms, even "organs of extreme perfection" like the human eye.

In the Origin, Darwin presents an enormous quantity of evidence that natural selection is not only a possible explanation of the origin of species, but that it is the only reasonable one. The data ranges from the pattern of development revealed in the fossil record, to facts about the geographical distribution of organisms, to anatomical and developmental similarities between otherwise very different living things.

Darwin demonstrates that his view can provide satisfying explanations of such matters, while from the point of view of those who believe in divine creation, they remain conundrums.

For instance, the forelimbs of humans, cats, bats, porpoises and horses perform very different functions and have very different forms, but remarkably share the same underlying bone structure. This only makes sense if all these creatures had a common ancestor in the distant past.

- - - - - - - - - - - - - - - -

EVEN THOUGH Darwin avoided the issue of human evolution in the Origin (a subject he was later to discuss at length in The Descent of Man), its publication inevitably sparked intense controversy. The eminent geologist Adam Sedgwick condemned Darwin's views for their "unflinching materialism," and figures such as Samuel Wilberforce, the Bishop of Oxford, attacked evolution from a religious perspective.

But it was precisely Darwin's materialism that explains the enthusiasm of his contemporaries Karl Marx and Frederick Engels for his new theory. Less than a month after the Origin was published, Engels remarked in a letter to Marx: "Darwin, whom I am just now reading, is splendid."

Marx himself read the Origin the following year and commented to Engels, "Although it is developed in the crude English style, this is the book which contains the basis in natural history for our own view." Several years later, Marx sent Darwin an inscribed copy of Das Kapital (although the story that he wanted to dedicate the second edition of this work to Darwin is a myth).

Although Darwin didn't engage in the public debate around The Origin, several younger scientists, including Joseph Hooker and Thomas Huxley, came to his defense. Within less than a decade, the bulk of the scientific establishment had been won over to evolution, although it took longer for natural selection to be accepted as the central mechanism.

Darwin's ideas were initially viewed as a challenge to the existing social order, but attempts were soon being made to use them in its support. The political theorist Herbert Spencer formulated the doctrine of Social Darwinism, defending laissez-faire economics on the grounds that it represented the principle of the "survival of the fittest" applied to human society.

Darwin's cousin, Francis Galton, founded the eugenics movement, which viewed social inequalities as having a biological basis and advocated intervention to "improve" the human stock.

But while there have been many attempts to link Darwin's ideas to the claim that social inequalities are biologically determined, and while Darwin undoubtedly shared many of the prejudices of his era, there is evidence of the opposite--that his biological theories were shaped by a commitment to human equality.

Darwin was horrified by slavery, and from an early age was a committed abolitionist who believed that all men are brothers. According to a new book by Adrian Desmond and James Moore, his convictions played an important role in leading him to the idea of the common descent of all organisms.

New attempts to use Darwinian ideas to explain social inequality have emerged in recent decades, including sociobiology and evolutionary psychology, which argue that evolution has shaped human beings to live in hierarchical, competitive societies.

But the history of human evolution reveals that the distinctive characteristic of our species is its flexibility, and that for most of human history, our ancestors lived in societies based on common ownership, cooperation and equality.

While Darwin's ideas have been misused by defenders of the status quo, they continue to come under attack from religiously motivated critics who advocate creationism or its somewhat more sophisticated variant the theory of "intelligent design."

The truth is, however, that Darwin had already refuted such ideas 150 years ago. Today, they are utterly without merit, and represent an attack not just on evolutionary biology but on scientific rationality itself. Although Darwin did not get everything right, the evidence for evolution has only increased since his death in 1882.

Darwin's ideas represent one of the great achievements of humanity's efforts to understand the natural world. Properly understood, they should be part of the arsenal of everyone fighting for progressive social change today.

What else to read

A collection of Darwin's writings can be found in The Darwin Reader [2], edited by Mark Ridley. Ridley is also the author of How to Read Darwin [3], a short and clear introduction. Darwin's complete works [4] are now available online.

The best biography of Darwin is Adrian Desmond and James Moore's Darwin: The Life of a Tormented Evolutionist [5]. Desmond and Moore have also just published Darwin's Sacred Cause: How a Hatred of Slavery Shaped Darwin's Views on Human Evolution [6].

For those interested in the debate around creationism and "intelligent design," Philip Kitcher's Living With Darwin: Evolution, Design, and the Future of Faith [7] is a good introduction. The debate is put into a broader historical context in Critique of Intelligent Design: Materialism versus Creationism From Antiquity to the Present [8] by John Bellamy Foster, Brett Clark and Richard York.

Finally, Ever Since Darwin [9], a collection of essays by the late Stephen Jay Gould, explores the continuing relevance of Darwin's ideas and criticizes their misappropriation by biological determinists of various stripes.

Happy birthday to a revolutionary evolutionist

by Megan Cornish

Image removed.    
It's no wonder that students in the U.S. score below average on international science achievement tests. They certainly have few role models who demonstrate the power of logical thinking! Politicians, CEOs, and the media stun with a flood of cynical doublespeak. Giving trillions of dollars away to banks is upholding "free enterprise," for example, while opposing gay marriage is defending "family values"!

In the middle of such intentional muddle comes a breath of fresh air: the 200th anniversary of Charles Darwin's birth and the 150th anniversary of his great work, On the Origin of Species by Means of Natural Selection. There will be a lot of revisiting of his monumental theory this year, and perhaps this will do us all some good.

The idea that forms of life evolve, rather than springing up as God's unchanging creations, had been developing for a century when Origin of Species was published. Darwin's contribution was to explain how evolution works.

Small variations between individuals in a species occur by chance. These sometimes result in a trait that either allows an individual to reproduce more successfully than other group members or helps it to exploit new sources of food or geographical areas. The beneficial trait is passed on to offspring.

Species gradually change. Over time, a quantity of small changes make a qualitative difference and new species emerge, while old ones die out. That is natural selection.

This is revolutionary stuff, and it caused an explosion that still reverberates today. Evolution means that the old order of things does not have to last forever; in fact, it cannot last forever. And the nature of the human species is not static and supernaturally defined, but fluid and conditioned by our material and social circumstances.

Darwin was one of many intellectual bomb-throwers of his time. Many modern spheres of investigation were just coming into being. Capitalism was still a rising star, able to make progressive use of technological discoveries. These were the days before it began to burn itself out and learned to fear exploration into climate science, or technologies that would reduce oil profits, or embryonic stem cell research. And, especially, before economics ceased to be an area of honest examination and became mere cheerleading for a dying system.

But, before that happened, the physical scientist Darwin had his counterparts in the social sciences: his contemporaries Karl Marx and Frederick Engels. The Communist Manifesto appeared in 1848, just before a revolutionary upsurge in Europe and 11 years before Darwin's Origin of Species.

Building on the work of philosophers and economists before them, Marx and Engels came up with a perspective that parallels Darwin's in its explanation of how society evolves. Every social system is born, develops, and dies, they said, because of identifiable historical and material reasons; change results from the interaction of one thing with another. No system can be eternal.

They recognized that their method of analysis, called dialectical materialism, applies both to social and natural reality. It's the method scientists use, whether or not they know the term. Engels wrote a brilliant treatment of its application to the physical world — including an appreciative analysis of Darwin — in his book Dialectics of Nature.

Darwin, Marx and Engels were kindred spirits because they saw things in this logical, dynamic way. Darwin's scientific approach led him to instinctively oppose oppression. He was horrified by the slavery he saw in Brazil. He objected to the exploitation of aboriginal peoples. His emphasis on human beings as one species was fundamentally at odds with the racist notion of "subhumans." And — oh, the horror! — he pointed out that humans are an integral part of the animal kingdom.

Darwin has much more in common with Marx and Engels than with the so-called social Darwinists who twist his theory into a simplistic glorification of competition between individuals ("survival of the fittest") and use it to justify the dog-eat-dog nature of capitalism.

Actually, a key element for species survival — one Darwin recognized — is the capacity to cooperate. Without it, humans would have been dinner for the large cats of Africa, our ancestral home, long before we could create modern society.

In today's global crisis, too, it will be our ability to work together that will determine our survival. In order to end war, act to save our planet, and take the reins of power away from the obscenely rich few, the overwhelming majority must cooperate to take the next logical step. The wealth of our world is collectively created; when it is also collectively shared, we can guarantee a continuing future for Homo sapiens.

Let's use the brain that evolution gave us to make sure we have a 300th birthday of Charles Darwin to celebrate!
