catastrophism or uniformitarianism

In my last post, The Problem with Diachronic Extrapolation, I attempted to show how diachronic extrapolation, while the most familiar form of futurism, is often misleading because it fails to adequately account for synchronic interactions as a diachronic strategic trend develops. In other posts concerned with unintended consequences I have emphasized that, in the long term, unintended consequences often outweigh intended consequences. Unintended consequences are the result of synchronic interactions that were not foreseen, that were no part of diachronic agency, and those cases in which unintended consequences swamp intended consequences the synchronic interactions have proved more decisive in shaping the future than diachronic causality.

In my post on The Problem with Diachronic Extrapolation I made several assertions that clearly imply the limitation of inferences from the present to the future, which also implies the limitation of inferences from the present to the past. This brings up issues that go far beyond futurism.

In that post I wrote:

“…diachrony over significant periods of time cannot be pursued in isolation, since any diachronic extrapolation will interact with changed conditions over time, and this interaction will eventually come to constitute the consequences as must as the original trend diachronically extrapolated.”

…and…

“…the most frequent form of failed futurism is to take a trend in the present and to project it into the future, but any futurism worthy of the name must understand events in both their synchronic and diachronic context; isolation from succession in time is just as invidious as isolation from interaction across time…”

The reader may have noticed the resemblance of this species of failed futurism to uniformitarianism: instead of taking a strategic trend acting at present and extrapolating it into the future, uniformitarianism takes a physical force acting in the present and extrapolates it into the future (or, as is more likely the case in geology, into the past). This idea of uniformitarianism is usually expressed as, “the present is key to the past,” and we might similarly express the parallel form of futurism as being, “the present is key to the future.” These two claims — the present is the key to the past and the present is the key to the future — are logically equivalent since, as I pointed out previously, every present is the future of some past, and the past of some future.

Since these interpretations of uniformitarianism involve uniformity across past and future, these formulations closely resemble formulations of induction also stated in terms of past and future, as when the logical problem of induction is formulated, “Will the future be like the past?” It is at this point that the philosophy of time, the philosophy of history, the philosophy of science, and futurism all coincide, because it concerns a problem that all have in common.

Stephen Jay Gould noticed this similarity of uniformitarianism and induction in his first published paper, “Is uniformitarianism necessary?” Gould, of course, become famous for his critique of uniformitarianism, and for this alternative to it, punctuated equilibrium (for which he shares the credit with Niles Eldredge). In this early paper by Gould, Gould distinguished between substantive uniformitarianism and methodological uniformitarianism. He tried to show that the former is simply false, and the the latter, methodological uniformitarianism, is now subsumed under the scientificity of geology and paleontology. Here is now Gould put it:

“…we see that methodological uniformitarianism amounts to an affirmation of induction and simplicity. But since these principles belong to the modern definition of empirical science in general, uniformitarianism is subsumed in the simple statement: ‘geology is a science’. By specifically invoking methodological uniformitarianism, we do little more than affirm that induction is procedurally valid in geology.”

Stephen Jay Gould, “Is uniformitarianism necessary?” American Journal of Science, Vol. 263, March 1965, p. 227

That is to say, the earth sciences use the scientific method, which Gould characterizes in terms of inductive logic and the principle of parsimony (I would argue that Gould is also assuming methodological naturalism) — therefore everything that is worth saving in uniformitarianism is already secured by the scientific status of geology, and therefore uniformitarianism is dispensable. Having once served an important function in science, uniformitarianism has now, Gould contends, become an obstacle to progress.

As I noted above, Gould didn’t merely assert that uniformitarianism was no longer necessary, but devoted his career to arguing for an alternative, punctuated equilibrium, which asserts that long period of stasis are interrupted by catastrophic discontinuities. While much has been written about uniformitarianism vs. punctuated equilibrium, I see this as the thin end of the wedge for considering all kinds of alternatives to strict uniformitarianism, and to his end I think we would do well to explore all possible patterns of development, whether uniform (slow, gradual, incremental), punctuated (sudden, catastrophic, discontinuous), or otherwise.

Of course, we could easily produce more sophisticated formulations of uniformitarianism that would avoid the subsequent problems that have been raised, but this is the path that leads to Ptolemaic epicycles and attempts to “save the appearances,” whereas what we want is a rich mixture of theoretical innovation from which we can try many different models and select for further development those that are most true to the world.

Since the philosophy of time, the philosophy of history, the philosophy of science, and futurism all coincide at the point represented by the problem of the relationship of parts of time to other parts of time (and the idea of temporal parts is itself philosophical contested), all of these disciplines stand to learn something of value from exploring alternatives to uniformitarianism. In so far as futurism is dominated by nomothetic diachrony, and constitutes a kind of historical uniformitarianism, very different forms of futurism might emerge from a careful study of the alternatives to uniformitarianism, or merely from a recognition that, as Gould put, uniformitarianism is no longer necessary and something of an anachronism. If there is anything of which futurists ought to beware, being an anachronism must be close to the top of the list.

Darwin’s Cosmology

12 February 2012

Sunday


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.

The Cougar (Male) by John Woodhouse Audubon, An illustration from The Viviparous Quadrupeds of North America by John James Audubon and John Bachman, originally published in three volumes (1845-1848).

I usually avoid local news, but when I visit my mother she always brings out clippings from the local paper that she has been saving and which she urges me to read, also mailing some of these to my sisters who live elsewhere and therefore don’t see the local paper on a regular basis. Most of these items are of no interest to me, but I was very intrigued by a guest editorial in the Daily Astorian, written by Matt Winters of the Chinook Observer. My mother tells me that she always looks forward to Mr. Winters’ columns.

The guest editorial was titled, “An unforgettable scream in the night,” and opens with the motif of a cougar scream. As I have myself heard a cougar scream, I know how blood-curdling it sounds. It isn’t really possible to explain it, but it is a sound that inspires instinctive fear. And it is probably a great evolutionary advantage to all primates to react with this instinctive fear to the sound of a big cat, as, if you get caught by one, you will be killed and eaten. To a mountain lion, we are mere prey.

Mr. Winters describes the scream of a cougar as a “hate-filled screech” and goes on to reflect:

There is much in the minds of other species that we can make no pretense of understanding.

In writing it is often regarded as an amateurish stunt to anthropomorphize — to attach human characteristics to animals. To say that a cougar is expressing hatred or that a raven is amused by is own reflection is to risk a figurative pat on the head, as if you are too simple-minded to know the vast difference between we suave humans and those buffoonish beasts.

More and more, I suspect that they are more like us and we are more like them than anyone wants to acknowledge. Maybe our snobbish attitude grew up to salve our consciences about treating so many creatures with such wanton cruelty…

While I disagree with Mr. Winters that a cougar’s scream sounds “hate-filled” (though it certainly is a fear-inspiring sound), more importantly I agree with the implied criticism of anthropomorphization, and this got me to thinking. The idea that anthropomorphization is a fallacy is itself a fallacy, and it is a fallacy based on an assumption of discontinuity between human beings and nature. In other words, the critique of anthropomorphization is a relic of the nature/culture dichotomy.

In The Continuity of Civilization and Natural History I made the following argument:

“…in so far as civilization is entirely the product of a set of behavioral adaptations that have made it possible for human beings to thrive in any habitat, we can view civilization as being continuous with the behavioral adaptations of natural history and therefore as exemplifying no historical novelty whatsoever. Thus the advent of human civilization does not represent historical discontinuity and no historical period is originated with the advent of human history.”

The continuity of civilization and natural history is, of course, only a special case of the continuity of human beings with the natural history that produced us. Darwin repeatedly appealed to what is sometimes called the saltation principle: Natura non facit saltum, i.e., nature does not make leaps. While modern science made many of its early gains by rejecting the authority of Aristotle enshrined by the Scholastics, the saltation principle is essentially a corollary of Aristotle’s dictum that nature abhors a vacuum. The absence of a vacuum means natural continuity, and this is also expressed by the uniformitarianism of geology before Darwin, and especially in Lyell, who profoundly influenced Darwin. For all our intellectual revolutions, there is a great deal of continuity here as well.

The continuity of of our ideas through history is an expression of the stability of what Braudel called the structures of everyday life. I have made this point in several posts, starting with Life and Landscape, and more recently coming to the formulation that, “…the landscape a people comes from shapes the life and character of that people, and this way of life in turn shapes the ideas of that people. Thus ideology is a highly derived form of geography.” (in Fifty Years of Brasília), further elaborated the next day as, “…ideology is the higher geopolitics, and philosophy is the higher ideology.” (in How the World Works: Philosophical Version)

A humorous take on the Aristotelian-Scholastic principle that nature abhors a vacuum.

If the critique of anthropomorphization is in fact a fallacy derived from suspending the continuity of the world, i.e., introducing a leap into nature, what then is the alternative? There are at least two alternatives, and I suspect that each is appropriate in its own context, whatever the appropriate context might be. Firstly, there is the possibility of validly inferring human qualities in other species, which then simply becomes an extension of the ancient philosophical puzzle of other minds (which I briefly considered in The Eye of the Other, inspired by an experience in Astoria, and so it ties in neatly here). Secondly, there is the possibility of non-anthropomorphization, which would be something like the objectification of human qualities (this isn’t the best formulation, but hopefully I will hit on a happier phrasing at some time in the future).

This second alternative bears some intuitive resemblance to the recent philosophical phenomenon of object-oriented ontology, which I have briefly discussed in several posts. To employ the non-anthropocentric discourses of the natural sciences to describe the human condition might be construed as a dehumanizing form of objectification, but it can also be liberating to take leave of the tendentious histories of the past. And one needn’t be an object-oriented ontologist to assume this perspective: William McNeill’s deservedly well-known book Plagues and Peoples adopts a natural historical approach to human history, and this is also the central task of the naturalistic conception of history.
