Darwin’s Cosmology

12 February 2012


Today is Darwin’s birthday, and therefore an appropriate time to celebrate Darwin by a mediation upon his work. No one has influenced me more than Darwin, and I always find the study of his works to be intellectually rewarding. I also read (and listen to) quite a number of books about Darwin. Recently I listened to Darwin, Darwinism, and the Modern World, 14 lectures by Dr. Chandak Sengoopta. While I enjoyed the lectures, I sharply differed from many of Dr. Sengoopta’s interpretations of Darwin’s thought. One theme that Dr. Sengoopta returned to several times was a denial that Darwin had anything to say about the ultimate origins of life. Each time that Dr. Sengoopta made this point I found myself grow more and more irritated.

To say that Darwin had nothing to say about the ultimate origins of life may be technically correct in a narrow sense, but I do not think that it is an accurate expression of Darwin’s vision of life, which was sweeping and comprehensive. While it may be a little much to say that Darwin ever entertained ideas that could accurately be called “Darwin’s cosmology,” it is obvious in reading Darwin’s notebooks, in which he recorded thoughts that never made it into his published books, his mind ranged far and wide. It is almost as though, once Darwin made the conceptual breakthrough of natural selection he had discovered a new world.

In characterizing Darwin’s thought in this way I am immediately reminded of a famous letter that Janos Bolyai wrote to his father after having independently arrived at the idea of non-Euclidean geometry:

“…I have discovered such wonderful things that I was amazed, and it would be an everlasting piece of bad fortune if they were lost. When you, my dear Father, see them, you will understand; at present I can say nothing except this: that out of nothing I have created a strange new universe. All that I have sent you previously is like a house of cards in comparison with a tower. I am no less convinced that these discoveries will bring me honor than I would be if they were complete.”

Darwin, too, discovered wonderful things and created the strange new universe of evolutionary biology, though it came on him rather slowly — not in a youthful moment that could be recorded to a letter in his father, and not in a fit of fever, as the idea of natural selection came to Wallace — as the result of many years of ruminating on his observations. But the slowness with which Darwin’s mind worked was repaid with thoroughness. Even though Darwin was the first evolutionist in the modern sense of the term, he must also be accounted among the most complete of all evolutionary thinkers, having spent decades thinking through his idea with a Platonic will to follow the argument wherever it leads.

Given that Darwin himself thought that making the idea of natural selection public was like “confessing to a murder,” the fragments of Darwin’s cosmology must be sought in his latter and notebooks as much as in his published works. As for the origins of life, narrowly considered, apart from the cosmological implications of life, Darwin openly speculated on a purely naturalistic origin of life in a letter to Joseph Hooker:

“It is often said that all the conditions for the first production of a living organism are now present, which could ever have been present. But if (and oh what a big if) we could conceive in some warm little pond with all sorts of ammonia and phosphoric salts, — light, heat, electricity &c. present, that a protein compound was chemically formed, ready to undergo still more complex changes, at the present day such matter would be instantly devoured, or absorbed, which would not have been the case before living creatures were formed.”

Darwin’s 1871 letter to Joseph Hooker

What has widely come to be known as “Darwin’s warm little pond” sounds like nothing so much as the famous Stanley L. Miller electrical discharge experiment.

Darwin revealed his consistent naturalism in his rejection of teleology in a letter to Julia Wedgwood, where he indirectly refers to his slow, steady, cumulative mode of thinking (quite the opposite of revelation):

“The mind refuses to look at this universe, being what it is, without having been designed; yet, where would one most expect design, viz. in the structure of a sentient being, the more I think on the subject, the less I can see proof of design.”

Darwin’s letter of 11 July 1861 to Miss Julia Wedgwood

This same refusal continues to a sticking point to the present day, since, like so much that we learn from contemporary science, appearances are deceiving, and the reality behind the appearance can be so alien to the natural constitution of thue human mind that it is rejected as incomprehensible or unthinkable. That Darwin was able to think the unthinkable, and to so with a unparalleled completeness at a time when no one else was doing so, is testimony to the cosmological scope of his thought.

One of the most memorable passages in all of Darwin’s writings is the last page or so of the Origin of Species, which touches not a little on cosmological themes. Take, for instance, the “tangled bank” passage:

“It is interesting to contemplate an entangled bank, clothed with many plants of many kinds, with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other, and dependent on each other in so complex a manner, have all been produced by laws acting around us.”

Besides anticipating the evolutionary study of ecology and complex adaptive systems long before these disciplines became explicit and constituted their own sciences, Darwin here subtly invokes a law-like naturalism that both suggests Lyell’s uniformitarianism while going beyond it.

Darwin places this law-governed naturalism in cosmological context in the last two sentences of the book, here also implicitly invoking Malthus, whose influence was central to his making the breakthrough to the idea of natural selection:

“Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.”

This famous passage from Darwin reminds me of a perhaps equally famous passage from Immanuel Kant, who concluded The Critique of Practical Reason with this thought:

“Two things fill the mind with ever new and increasing admiration and awe, the more often and steadily we reflect upon them: the starry heavens above me and the moral law within me. I do not seek or conjecture either of them as if they were veiled obscurities or extravagances beyond the horizon of my vision; I see them before me and connect them immediately with the consciousness of my existence. The first starts at the place that I occupy in the external world of the senses, and extends the connection in which I stand into the limitless magnitude of worlds upon worlds, systems upon systems, as well as into the boundless times of their periodic motion, their beginning and continuation. The second begins with my invisible self, my personality, and displays to me a world that has true infinity, but which can only be detected through the understanding, and with which . . . I know myself to be in not, as in the first case, merely contingent, but universal and necessary connection. The first perspective of a countless multitude of worlds as it were annihilates my importance as an animal creature, which must give the matter out of which it has grown back to the planet (a mere speck in the cosmos) after it has been (one knows not how) furnished with life-force for a short time.”

Both Darwin and Kant invoke both the laws of the natural world (and both, again, do so by appealing to grandeur of the heavens) and a humanistic ideal. For Kant, the humanistic ideal is morality; for Darwin, the humanistic ideal is beauty, but what Kant said of morality and the moral law is equally applicable, mutatis mutandis, to beauty. Darwin might equally well have said of “the fixed law of gravity” and of “endless forms most beautiful and most wonderful” that he saw them before himself and connected them immediately with the consciousness of his existence. Kant might equally well have said that there is “grandeur in this view of life” that embraces both the starry heavens above and the moral law within.

Darwin did not express himself (and would not have expressed himself) in these philosophical terms; he was a naturalist and a biologist, not a philosopher. But Darwin’s naturalism and biology were so comprehensive to have spanned the universe and to have converged on an entire cosmology — a cosmology, for the most part, not even suspected before Darwin had done his work.

There is a sense in which Darwin fulfilled Marx’s famous pronouncement, from this Theses on Feuerbach, such that: “Philosophers have only interpreted the world in various ways; the point is to change it.” Darwin, however, did not change the world by fomenting a revolution; Darwin changed the world by thinking, like a philosopher. In this sense, at least, Darwin must be counted among the greatest philosophers.

I would be a rewarding project to devote an entire book to the idea of Darwin’s Cosmology. I know that I have not even scratched the surface here, and have not come near to doing justice to the idea. It would be a rewarding project to think through this idea as carefully as Darwin thought through his ideas.

Happy Birthday Charles Darwin!
