Parochialism, ironically, knows no bounds. Our habit of blinkering ourselves — what visionary poet William Blake called “mind-forged manacles” — is nearly universal. Sometimes even the most sophisticated minds miss the simple things that are staring them in the face. Usually, I think this is a function of the absence of a theoretical context that would make it possible to understand the simple truth staring us in the face.
I have elsewhere written that one of the things that makes Marx a truly visionary thinker is that he saw the industrial revolution for what it was — a revolution — even while many who lived through this profound series of events where unaware that they were living through a revolution. So even if one’s theoretical context is almost completely wrong, or seriously flawed, the mere fact of having the more comprehensive perspective bequeathed by a theoretical understanding of contemporary events can be enough to make it possible for one to see the forest for the trees.
Darwin wrote somewhere (I can’t recall where as I write this, but will add the reference later when I run across it) that from his conversations with biologists prior to publishing The Origin of Species he knew how few were willing to thing in terms of the mutability of species, but once he had made his theory public it was rapidly adopted as a research program by biologists, and Darwin suggested that countless facts familiar to biologists but hitherto not systematically incorporated into theory suddenly found a framework in which they could be expressed. Obviously, these are my words rather than Darwin’s, and when I can find the actual quote I will include it here, but I think I have remembered the gist of the passage to which I refer.
It would be comical, if it were not so pathetic, that one of the first responses to Darwin’s systematic exposition of evolution was for people to look around for “transitional” evolutionary forms, and, strange to say, they didn’t find any. This failure to find transitional forms was interpreted as a problem for evolution, and expeditions were mounted in order to search for the so-called “missing link.”
The idea that the present consists entirely of life forms having attained a completed and perfected form, and that all previous natural history culminates in these finished forms of the present, therefore placing all transitional forms in the past, is a relic of teleological and equilibrium thinking. Once we dispense the unnecessary and mistaken idea that the present is the aim of the past and exemplifies a kind of equilibrium in the history of life that can henceforth be iterated to infinity, it becomes immediately obvious that every life form is a transitional form, including ourselves.
A few radical thinkers understood this. Nietzsche, for example, understood this all-too-clearly, and wrote that, “Man is a rope stretched between the beasts and the Superman — a rope over an abyss. A dangerous crossing, a dangerous wayfaring, a dangerous looking-back, a dangerous trembling and halting. What is great in man is that he is a bridge and not a goal..” But assertions as bold as that of Nietzsche were rare. Darwin himself didn’t even mention human evolution in The Origin of Species (though he later came back to human origins in The Descent of Man): Darwin first offered a modest formulation of a radical theory.
So what has all this in regard to Marx and Darwin to do with the great filter, mentioned in the title of this post? I have written many posts about the Fermi paradox recently without ever mentioning the great filter, which is an important part of the way that the Fermi paradox is formulated today. If we ask, if the universe is supposedly teaming with alien life, and possibly also with alien civilizations, why we haven’t met any of them, we have to draw that conclusion that, among all the contingencies that must hold in order for an industrial-technological civilization to arise within our cosmos, at least one of these contingencies has tripped up all previous advanced civilizations, or else they would be here already (and we would probably be their slaves).
The contingency that has prevented any other advanced civilization in the cosmos from beating us to the punch is called the great filter. Many who write on the Fermi paradox, then, ask whether the great filter is in our past or in our future. If it is in our past, we have good reason to hope that our civilization can be an ongoing concern. If it is in our future, we have a very real reason to be concerned, since if no other advanced civilization has made it through the great filter in their development, it would seem unlikely that we would prove the exception to that rule. So a neat way to divide the optimists and the pessimists in regard to the future of human civilization is whether someone places the great filter in the past (optimists) or in the future (pessimists).
Human beings are the only species (on the only biosphere known to us) known to have created industrial-technological civilization. This is our special claim to intelligence. But before us there were numerous precursor species, and many hominid species that have since gone extinct. Many of these hominids (who cannot all be called human “ancestors” since many of them were dead ends on the evolutionary tree) were tool users, and it is for this reason that I noted in Civilization and the Technium that the technium is older than civilization (and more widely distributed than civilization). But now we are only only remaining hominid species on the planet. So in the past, we can already see a filter that has narrowed down the human experience to a single sentient and intelligent species.
Writers on the technological singularity and on the post-human and even post-biological future have speculated on a wide variety of possible scenarios in which post-human beings, industrial-technological civilization, and the technium will expand throughout the cosmos. If these events come to past, the narrowing of the human experience to a single biological species will eventually be followed by a great blossoming of sentient and intelligent agents who may not be precisely human in the narrow sense, but in a wider sense will all be our descendants and our progeny. In this eventuality, the narrow bottleneck of humanity will expand exponentially from its present condition.
Looking at the present human condition from the perspective of multiple predecessor species and multiple future species, we see that the history of sentient and intelligent life on earth has narrowed in the present to a single hominid species. The natural history of intelligence on the Earth has all its eggs in one basket. Our existence as the sole sentient and intelligent species means that we are the great filter.
If we survive ourselves, we will have a right to be optimistic about the future of intelligent life in the universe — but not until then. Not until we have been superseded, not until the human era has ended, ought we to be optimistic.
Man is a narrow strand stretched between pre-human diversity and post-human diversity.

19 February 2012
Recently (in Don’t Cry for the Papers) I wrote that, “Books will be a part of human life as long as there are human beings (or some successor species engaged in civilizational activity, or whatever cultural institution is the successor to civilization).” While this was only a single line thrown out as an aside in a discussion of newspapers and magazines, I had to pause over this to think about it and make sure that I would get my phrasing right, and in doing so I realized that there are several ideas implicit in this formulation.
Since I make an effort to always think in terms of la longue durée, I have conditioned myself to note that current forms (of civilization, or whatever else is being considered) are always likely to be supplanted by changed forms in the future, so when I said that books, like the poor, will always be with us, for the sake of completeness I had to note that human forms may be supplanted by a successor species and that civilization may be supplanted by a a successor institution. Both the idea of the post-human and the post-civilizational are interesting in their own right. I have briefly considered posthumanity and human speciation in Against Natural History, Right and Left (as well as other posts such as Addendum on the Avoidance of Moral Horror), but the idea of a successor to civilization is something that begs further consideration.
Now, in the sense, everything that I have written about futurist scenarios for the successor to contemporary industrial-technological civilization (which I have described in Three Futures, Another Future: The New Agriculturalism, and other posts) can be taken as attempts to outline what comes after civilization in so far as we understand civilization as contemporary industrial-technological civilization. This investigation of post-industrial civilization is an important aspect of an analytic and theoretical futurism, but we must go further in order to gain a yet more comprehensive perspective that places civilization within the longest possible historical context.
I have adopted the convention of speaking of “civilization” as comprising all settled, urbanized cultures that have emerged since the Neolithic Agricultural Revolution. This is not the use that “civilization” has in classic humanistic historiography, but I have discussed this elsewhere; for example, in Jacob Bronowski and Radical Reflection I wrote:
…Bronowski refers to “civilization as we know it” as being 12,000 years old, which means that he is identifying civilization with the Neolithic Agricultural Revolution and the emergence of settled life in villages and eventually cities.
Taking this long and comprehensive view of civilization, we still must contrast civilization with its prehistoric antecedents. When one realizes that the natural sciences have been writing the history of prehistory since the methods, the technologies, and the conceptual infrastructure for this have been developed since the late nineteenth century, and that paleolithic history itself admits of cultures (the Micoquien, the Mousterian, the Châtelperronian, the Aurignacian, and the Gravettian, for example), it becomes clear that “culture” is a more comprehensive category than “civilization,” and that culture is the older category. The cultures of prehistory are the antecedent institutions to the institution of civilization. This immediately suggests, in the context of futurism, that there could be a successor institution to civilization that no longer could be strictly called “civilization” but which still constituted a human culture.
Thus the question, “What comes after civilization?” when understood in an appropriately radical philosophical sense, invites us to consider post-civilizational human cultures that will not only differ profoundly from contemporary industrial-technological civilization, but which will differ profoundly from all human civilization from the Neolithic Agricultural Revolution to the present day.
Human speciation, if it occurs, will profoundly affect the development of post-human, post-civilizational cultural institutions. I have mentioned in several posts (e.g., Gödel’s Lesson for Geopolitics) that Francis Fukuyama felt obligated to add the qualification to this “end of history” thesis that if biotechnology made fundamental changes to human beings, this could result in a change to human nature, and then all bets are off for the future: in this eventuality, history will not end. Changed human beings, possibly no longer human sensu stricto, may have novel conceptions of social organization and therefore also novel conceptions of social and economic justice. From these novel conceptions may arise cultural institutions that are no longer “civilization” as we here understand civilization.
Above I wrote, “human speciation, if it occurs,” and I should mention that my only hesitation here is that social or technological means may be employed in the attempt to arrest human evolution at more-or-less its present stage of development, thus forestalling human speciation. Thus my qualification on human speciation in no way arises from a hesitation to acknowledge the possibility. As far as I am concerned, human being is first and foremost biological being, and biological being is always subject to natural selection. However, technological intervention might possibly overtake natural selection, in which case we will continue to experience selection as a species, but it will be social selection and technological selection rather than natural selection.
In terms of radical scenarios for the near- and middle-term future, the most familiar on offer at present (at least, the most familiar that has some traction in the public mind) is that of the technological singularity. I have recounted in several posts the detailed predictions that have been made, including several writers and futurists who have placed definite dates on the event. For example, Vernor Vinge, who proposed the idea of the technological singularity, wrote that, “Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended.” (This is from his original essay on the technological singularity published in 1993, which places the date of the advent of the technological singularity at 2023 or sooner; I understand that Mr. Vinge has since revised his forecast.)
To say that “the human era will be ended,” is certainly to predict a radical development, since it postulates a post-human future within the life time of many now living today (much like the claim that, “Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.”). If I had to predict a radical post-human future in the near- to middle-term future I would opt not for post-human machine intelligence but for human speciation facilitated by biotechnology. This latter scenario seems to me far more likely and far more plausible than the technological singularity, since we already have the technology in its essentials; it is only a matter of refining and applying existing biotechnology.
I make no predictions and set no dates because the crowding of seven billion (and counting) human beings on a single planet militates against radical changes to our species. Social pressures to avoid speciation would make such a scenario unlikely in the near- to middle-term future. If we couple human speciation with the scenario of extraterrestrialization, however, everything changes, but this pushes the scenario further into the future because we do not yet possess the infrastructure necessary to extraterrestrialization. Again, however, as with human speciation through biotechnology, we have all the technology necessary to extraterrestrialization, and it is only a matter of refining and applying existing technologies.
From this scenario of human speciation coupled with extraterrestrialization there would unquestionably emerge post-human, post-civilizational cultural institutions that would be propagated into the distant future, possibly marginalizing, and possibly entirely supplanting, human beings and human civilization as we know it today. It is to be expected that these institutions will be directly related to the way of life adopted in view of such a scenario, and this way of life will be sufficiently different from our own that its institutions and its values and its norms would be unprecedented from our perspective.
