Transhumanism and Adaptive Radiation

by Paul Gilster on May 29, 2015

Centauri Dreams regular Nick Nielsen here tackles transhumanism, probing its philosophical underpinnings and its practical consequences as civilization spreads outward from the Solar System. In a sense, transhumanism is what humans have always done, the act of transcendence through technology being a continuing theme of our existence. But accelerating technologies demand answers about human freedom in the context of a species that will inevitably bifurcate as it takes to the stars. Think of the ‘Cambrian explosion’ as a model as we consider what is to come. The author’s philosophy often takes him into mathematics (hence a digression on Georg Cantor and set theory), but the prolific Nielsen (Grand Strategy: The View from Oregon and Grand Strategy Annex) always has the long result in mind, a human future that grows and changes with us in a galactic diaspora and beyond.

0. Introduction: Synchronic and Diachronic Historiography


One of the most difficult aspects of thinking about the future is to see it not as Balkanized fragments, but to capture a glimpse of the whole, the big picture, and how the parts of the whole are related to each other. Complex wholes composed of diverse and originally separate elements are not always so elusive. In the experience of the individual, the separate deliverances of our senses, and the stimulation of thousands upon thousands of nerve endings, are synthesized in a single, unified narrative of conscious experience. [1] In so far as history aspires to be a single, unified narrative of the world entire, we would ideally like to see a conception of history as seamless as individual experience. Yet we routinely fail to see the past whole—few have the requisite knowledge to possess anything like a holistic perspective—so it should be no surprise that we fail to see the future whole. Nevertheless, we can make the attempt.

Historians make a distinction between the diachronic and the synchronic that can be helpful here—if we understand what these terms signify. It is often said that the diachronic perspective is through time while the synchronic perspective is across time. I have never found this very enlightening, so I explain it like this: diachrony is succession in time and synchrony is interaction in time. For example, the history of a single technology—say, chemical rockets—exhibits a sequence of developments, accidents, setbacks, triumphs, and the like that can be told as a unified and linear narrative. But no single technology or its history occurs in a vacuum; it interacts not only with other technologies, but also with economics, politics, diplomacy, and a myriad of other factors in its development. A synchronic history of the development of a single chemical rocket—say, the Saturn V booster for the Apollo program—would contextualize the technological effort within the many lives of the individuals involved in the program, these lives in the context of the Space Race, the Space Race within the Cold War, and the Cold War within post-WWII economic, political, and diplomatic superpower competition between former WWII allies. And it doesn’t end there.

A distinction between diachronic and synchronic historiography implies a parallel distinction between diachronic and synchronic futurism. Indeed, I would go farther and assert that within big history the two are one: we should not distinguish in principle between past and future, but should attempt to construct a framework of historical understanding that incorporates both. A big history of civilization that includes the ten thousand years of development up to the present must also look forward to at least the next ten thousand years, which will see the transition to spacefaring civilization if civilization does not stagnate or does not self-destruct.

In the spirit of a synchronic big history of civilization, then, I would like to develop some ideas regarding what might loosely be called “transhumanism” in order to better understand the transition to spacefaring civilization in the context of developments that will be simultaneously occurring with the agents of this transition. [2]

1. Planetary Constraints upon Civilization

Technological developments in the next one to two hundred years offer the potential of selectively eliminating certain constraints on human life and civilization that have defined the human condition since its emergence. Longevity technologies may alter or eliminate (for all practical purposes) temporal constraints on human life; leaving Earth may alter or eliminate spatial constraints of planetary life, as well as the temporal constraint of the limited habitable period of Earth; genetic engineering and technological enhancement may alter or eliminate the limitations intrinsic to the human mind and human body. The joint elimination of spatial and human limitations suggests the possibility of individuals assuming any form they may choose in order to live in any environment that they choose. Energy technologies may alter or eliminate the limitations on the production and consumption of energy that have shaped the development of civilization.

It is not likely that all human constraints that can be eliminated will be eliminated, or that this will happen simultaneously, or that it will happen completely (i.e., absolutely). The development of technological enhancement cannot be predicted. It is one of the distinctive properties of industrial-technological civilization that it is shaped by unpredictable technological developments, much as agrarian-ecclesiastical civilization is shaped by unpredictable weather and theological controversies. However, the closer a technological enhancement is to the stage of engineering an industrial application, the more predictable that development becomes. At our present state of knowledge, longevity is less of a scientific problem than a problem of particular technologies and engineering the application of these technologies; we can expect these unfolding technological advances to continue to incrementally contribute to longevity. However, the problem of artificial intelligence (not to mention machine consciousness) still lacks an adequate scientific basis. An adequate science of intelligence and consciousness is a necessary prerequisite of technologies of AI (or, rather, machine consciousness), and technologies must be engineered into practical solutions before they can pass on to industrial application.

It is the fact of pervasive (and sometimes even petty) constraints on human freedom that makes this freedom open to changes in scope as a result of technological change. If human freedom were something ideal and absolute, it would not be subject to revision as a consequence of technological change, or any change in contingent circumstances. But while we often think of freedom as an ideal, it is rather grounded in pragmatic realities of action. If a lever or an inclined plane make it possible for you to do something that it was impossible to do without them, then these machines have expanded the scope of human agency; more choices are available as a result, and the degrees of human freedom are multiplied.

Consistent and predictable constraints result in forced choices and mutually exclusive alternatives; when constraints are weakened or eliminated, the forced choice between mutually exclusive alternatives is removed, history no longer converges according to the predictable patterns of the past, and history bifurcates repeatedly as different individuals and different social groups make different choices. Technologies of consciousness may even eliminate perennial existential dilemmas, allowing an individual to be in two places at the same time, or to pursue both of two mutually exclusive alternatives (if embodiment is eventually rendered entirely voluntaristic).

What we have experienced to date of history might be framed as sentient-intelligent beings and their civilizations under conditions of severe constraint — what I have called terrestrial conflation, as the constraints of our planetary existence force the efforts of historical agents to converge upon actions consistent with planetary constraints, therefore conflating forms of civilization that would be distinct under conditions of constraint less severe than those imposed by planetary habitation. Before we consider these planetary constraints in more detail, however, we must first consider human constraints and their amelioration.

2. Transcending Human Limitations

Transhumanism means many different things to many different people. There is a simple explanation for this. Human being admits of many limitations and many forms of finitude. If we define transhumanism as the lessening or elimination of some one limitation or of several limitations (i.e., the transcendence of finitude and limitations), then there are as many forms of transhumanism as there are limitations and forms of finitude (as well as combinations and permutations thereof) that a human being might transcend. [3]

It is arguable that transhumanism is simply a perennial expression of human nature as magnified by the lens of contemporary technology, and that there is nothing at all radically new about transhumanism, hence it ought not to pose any kind of threat, nor be perceived as a threat—moral, emotional, or intellectual. Recently in Astrobiology is island biogeography writ large I expressed this such that technology is the pursuit of biology by other means, though it is the pursuit of biological ends accelerated by technology. If the tempo of historical transcendence alone counts as a threat, then one can understand the perceived threat of transhumanism.

In other words, transhumanism is simply humanism. With the advent of cognitive modernity, when human beings began to make use of their generous encephalization endowment, they began a series of unprecedented innovations not previously explored or exploited by any other organism on our planet, and, in so doing, transcending limitations never before transcended in the history of terrestrial life. It is, then, human nature to continually transcend the human condition.

From this point of view of continual transcendence, there is no human nature. Human beings are whatever they make of themselves. This is a position prefigured in philosophy. Sartre denied that there is any such thing as human nature, but (at least in his early years) insisted upon radical human freedom. If human nature is conceived as an eternal essence that cannot be transcended, then Sartre is right and there is no human nature. But if freedom itself is human nature, the ability to transcend any fixed and static nature, then there is a human nature, but not a nature expressible in terms of essence or necessity. Human nature, under this interpretation, confounds any attempts to assign it limitations on the basis of essentialist definitions or necessary constraints.

Despite the fact that human beings have created a unique world for themselves by transforming (i.e., transcending) their environment, and in so doing have transcended limitations for hundreds of thousands of years (and perhaps for millions of years, if we count our bipedal tool-making pre-human ancestors), transhumanism in its contemporary formulations—i.e., contemporary transcendence of limitations never before transcended in the history of our planet—is viewed as a threat by many, and as an existential threat by some.

Transhumanism as an existential threat (which is, at the same time, an existential opportunity) defines the contemporary debate over transhumanism, such as it is, which is often found to deteriorate into the assertion and counter-assertion of conflicting points of view that concede nothing to subtle shades of meaning, feeling, and intention that are intrinsic dimensions of human life. And this debate has not been clarified by the wide diversity of meanings that have been attached to the term “transhumanism.” The two operative assumptions that define each party to the conflict are, on the one hand, that everyone would, if given the opportunity, choose to transcend their limitations, or to transcend some particular limitation, and, on the other hand, that no one would really want to transcend their limitations, because our limitations define who and what we are, however loathe we are to admit this.

To make this conflict more concrete, let us take a particular human limitation: mortality. Some assume that everyone would want to live forever, if only the means were available, while, on the other hand, some assume that no one would really want to live forever, if truly faced with that prospect. We know that the quest for eternal youth and eternal life are ancient themes in our civilization, that alchemists sought to formulate the elixir of life and that some of the conquistadors sought to find the Fountain of Youth in the wild exoticism of the New World. There is no question that some men are greedy of life, and if given the opportunity would seize the possibility of life everlasting without hesitation. The thoughtful critics of this attitude assume that most individuals eventually rise to a level of maturity that allows them to accept their mortality, and assert that if human beings were given a life freed of biological necessities that they would not know what to do with themselves, and, like the Cumaean Sibyl, would wish for a death that does not come.

One of the most familiar critiques of transhumanism is that we would eventually find the ennui of immortality unbearable (which says nothing as to whether we might put two or three hundred years to good use), and this is an objection that has been around since the heretically-minded have questioned the joys of an eternity of heaven, such as Milton put in the mouth of the rebel angel Mammon:

“Suppose he should relent
And publish Grace to all, on promise made
Of new Subjection; with what eyes could we
Stand in his presence humble, and receive
Strict Laws impos’d, to celebrate his Throne
With warbl’d Hymns, and to his Godhead sing
Forc’t Halleluiah’s; while he Lordly sits
Our envied Sovran, and his Altar breathes
Ambrosial Odours and Ambrosial Flowers,
Our servile offerings.” [4]

It is difficult to imagine anyone enjoying a heaven so described, and it would only become more hateful over time. Presumably some parallel to ennui holds for other forms of human enhancement (distinct from longevity) with which we might become bored or fatigued once we had our fill of the exercise of some new capacity.

It is an obvious, and unforgivable, oversimplification to assume that everyone wants to live forever or that no one really wants to live forever. Even without the prospect of living forever, we know that there are suicides who choose to not even live out their natural term on Earth. That, too, is part of the human condition. We have always had the opportunity to shorten our own lives, or indeed to shorten the lives of others. We have not, to date, had the wherewithal to extend our own lives or to extend the lives of others at will (except incrementally through the interventions of scientific medicine), though, as I have observed in Unfinished Business: Finitude, Contingency, and Openness, the finitude of human being is a contingency, and it is a contingency subject to change in the light of future contingencies. The determination of human being by what is perceived as biological necessity is an accident of history.

This dialectic of transhumanism — will we accept or reject enhancement? — we can see, is a non-constructive approach, and when we generalize beyond any particular limitation of human being (whether it be lifespan or anything else) we immediately understand the necessity of patiently surveying human limitations in detail and asking of each limitation, “Is this desirable or is this not desirable?” This question in turn, formulated in tertium non datur form, is another non-constructive conception, and we again see the need to adopt a more subtle approach. Each human limitation, then, must be weighed and considered on its own merits, precisely because the human condition is defined by a range of limitations that each bear differently upon life.

One way to do this would be through a thought experiment in which one can imagine presenting a human being of today with a distant human descendent, some millions of years in the future, having been subjected to technological interventions intended to ameliorate limitations, and ask whether this descendent is to be counted within the charmed circle of humanity. Better, a human being of today could be presented with a range of distant descendents, some of which would be attractive and readily claimed as one of our own, and some of which would be repulsive. [5]

3. Transhumanism and Reflection Principles: a Technical Digression

The transcendence of human finitude and limitation, whether in regard to any one particular limitation (such as our finite life span) or in regard to all human limitations, begs the question of which human limitations or how many human limitations might be ameliorated or eliminated. As an exercise, i.e., as a thought experiment, we could attempt to imagine human being having infinitely transcended all human limitations. We may characterize the removal of all human finitude and limitation as absolute transhumanism. What would absolute transhumanism look like? There may be a way to approach this question, though at first sight it would seem to transcend any finite human conception by definition.

In order to formulate a coherent conception of absolute transhumanism we will need to call upon the theoretical resources of set theory, and firstly we will refer to a distinction that Georg Cantor, the founder of set theory, made between the transfinite and the absolutely infinite. In one passage Cantor formulated this distinction in the following terms: “Totalities that cannot be regarded as sets (an example is the totality of all alephs as is shown above), I have already many years ago called absolute infinite totalities [absolut unendliche Totalitäten], which I sharply distinguish from transfinite sets.” [6]

Elsewhere Cantor makes the distinction that the totalities of infinite sets are increaseable while the absolute infinite cannot be increased in size. This is profoundly counter-intuitive, but in studying the set theoretical conception of infinity, i.e., the transfinite, one must become familiar with the idea that there are infinite sets of different powers (i.e., infinite sets can be smaller or larger), and indeed an infinite hierarchy of infinitudes. [7] Cantor’s distinction between the increasable transfinite and the unincreasable absolute infinite is particularly suggestive for transhumanism, as human enhancement can be characterized as the increase of human capabilities and human faculties (which is logically equivalent to the reduction or elimination of limitations). Absolute transhumanism, if it could be realized, would then be an unincreasable enhancement of humanity—an unattainable and inconsistent ideal—while transhumanism simpliciter admits of increase, i.e., consists of human enhancements that admit of further enhancement.

In so far as a realized transhumanist property is the transcendence of some limitation, the telos of this transcendence is to pass from the finitude defined by limitation to an infinitude defined by no limitation. Of course, human enhancement will begin with the transcendence of limitations that nevertheless remain finite, and it may well be impossible for any human faculty to converge onto the infinite; this infinite transcendence is, however, the telos of the transcendence, whether or not that telos is realized. [8]

How do we distinguish the removal of all human finitude from the absolute infinite? Here we must go a bit deeper into set theory. The absolute infinite of human being suggests a transhuman reflection principle: any property that holds of absolute transhumanism holds of some lesser transhumanism, i.e., the properties of absolute transhumanism are reflected in lesser transhumanisms.

Reflection principles are employed in set theory in the study of infinite sets. First explicitly discussed and formalized by Azriel Lévy [9], reflection principles (there are many of them) are set theoretical implementations of the idea that the properties of higher infinite sets are “reflected downward” and can be found also as properties of smaller infinite sets. Intuitive glosses on the reflection principle are legion, as are proposed formalizations; as in all formal thought, the idea behind reflection principles is open to variation and to alternative formulations. [10] Lévy himself wrote that reflection is, “the idea of the impossibility of distinguishing, by specified means, the universe from partial universes,” and that reflection principles, “…state the existence of standard models… which reflect in some sense the state of the universe.”

Since the idea behind reflection principles is not widely familiar and can be difficult to grasp at first, I will give a couple of additional explanations. Here is how Hao Wang expressed the intuitive basis of reflection principles:

“The universe of all sets is structurally indefinable. One possible way to make this statement precise is the following: The universe of sets cannot be uniquely characterized (i.e., distinguished from all its initial segments) by any internal structural property of the membership relation in it which is expressible in any logic of finite or transfinite type, including infinitary logics of any cardinal number. This principle may be considered a generalization of the closure principle. Further generalizations and refinements are in the making in recent literature. The totality of all sets is, in some sense, indescribable. When you have any structural property that is supposed to apply to all sets, you know you have not got all sets. There must be some sets that contain as members all sets that have that property.” [11]

For another example, here is how Mary Tiles explains the reflection principle:

“…there is no way, within the language of ZF, to characterize the whole set-theoretic universe, as opposed to some member of it (some Va). Every formula in the language of ZF, if true at all, will be true within some set which falls short of being the whole universe. So there is no way, from within ZF, of insisting that one is talking about all sets rather than about all sets up to a given rank.” [12]

It follows from the reflection principle that every property of the absolute infinite is to be found in some lesser infinitude. Absolute transhumanism could be understood as some lesser absolute infinite—more than a mathematical infinite, i.e., the transfinite, but less than the absolute infinite, which excludes nothing—or indeed as an infinitude that is provided for by a reflection principle.

As we saw above, Cantor defined the absolute infinite as an inconsistent totality that cannot be a set and that cannot be increased in size (it lies beyond the hierarchy of transfinite numbers). Transfinite numbers are infinite sets that can be increased in size; the size of an infinite set is established by one-to-one correspondence. Equipollent sets are of the same size. The definition of the an infinite set as a set that can be put in one-to-one correspondence with a proper subset of itself already prefigures the idea of reflection: the infinite set of even numbers “reflects” the infinitude of the infinite set of all natural numbers, with which even numbers can be put in one-to-one correspondence (the set of natural numbers and the set of even numbers are equipollent).

Perhaps this isn’t very helpful, so let me try another approach. The absolute infinite is a conception of the infinite that is infinite in every respect. It is not uncommon that naïve conceptions of the infinite implicitly invoke the absolute infinite, which is sometimes framed as an objection to the mathematical theory of the infinite, which is not concerned with the absolute infinite. As we have seen, Cantor called the absolute infinite an inconsistent multiplicity (and did so long before Russell’s paradox was known), and distinguished it from the transfinite. Transhumanism simpliciter, then, is parallel to the transfinite, while absolute transhumanism is different in its essential nature from transhumanism because its admittedly inconsistent properties cannot be increased.

Just as the unrestricted comprehension principle [13] results in contradictions, so too unrestricted reflection principles also result in contradictions, and so more subtle formulations of reflection principles have proved to be necessary to translate the informal and intuitive conception into rigorous and formal contexts. One way of rescuing comprehension is to relativize it to a property that marks off elements of the set already given, so that instead of asserting that any property whatsoever defines a set, it is asserted that any property defines a set within another set. (Cf. the text of note [13] above) A similar approach can be taken with reflection principles, so that a reflection principle is relativized to properties marked off from a set already given. This, finally, is how we distinguish the removal of all human finitude (absolute transhumanism) from the absolute infinite. Absolute transhumanism is a set of infinite properties potentially applicable to human beings nested within the infinite properties of the absolute infinite. In this way, we have a glimpse of absolute transhumanism.

With the idea of absolute transhumanism we find ourselves on the verge of theological problems, and here I am even more wary to tread than set theory, but in all honesty I cannot discuss absolute transhumanism without reference to related theological concepts, however much I would prefer to avoid the subject. In so far as absolute transhumanism would be characterized by omniscience, omnipresence, omnipotence, and eternity (among other “omni-” properties), the infinite personhood of absolute transhumanism is, in a sense, the culmination of the Feuerbachian idea that humanity, in worshipping the divine, is worshipping what is best in itself, and that which humanity may, in the fullness of time, come into as its own birthright. This theme is pervasive throughout Feuerbach’s works [14] and it is a testament to the tolerance of nineteenth century civilization that Feuerbach was able to develop these themes as extensively as he did without experiencing persecution. People in our own time have been persecuted for less.

For contingent reasons derived from the terrestrial origins of human being, human being could never ascend to absolute transhumanism—in some cases because omni-properties are inconsistent, and in some cases because they conflict with the physical structure of the world. For example, human being can never be eternal, because humanity has a beginning in time, and therefore is limited to future sempiternity. Human being cannot ascend to omnipotence, because omnipotence is contradictory: could the omnipotent transhuman being create a rock so heavy that the same being could not lift it? Human being cannot aspire to omnipresence, because omnipresence is not possible in a relativistic universe: the relativity of simultaneity entails that no being could be present simultaneously at all times and all places. These contradictions actually show us how fruitful the definition of transhumanism in terms of a reflection principle is, since we can clearly see that absolute transhumanism, like the absolute infinite, is an inconsistent totality. Thus the parallelism of infinitude and humanism holds on several levels.

4. The Thin End of the Wedge

We have already accepted, if not embraced, psychosocial and emotional enhancement, and a range of psychotropic medications are available for this purpose, although enhancement is conceptualized in terms of normativity. There is a similar acceptance of physical enhancement through performance enhancing drugs, though a certain opprobrium attaches to this—perhaps due to the fact that physical enhancement is more obviously enhancement that exceeds normative levels of performance. In terms of emotional and cognitive enhancement, our measures are more subjective, and the efficacy of drugs (such as, e.g., modafinil) are openly debated. There is as yet no consensus regarding whether the efficacy of such drugs is a placebo effect or genuinely nootropic, but the time will come when cognitive enhancement in the form of a pill is no longer debatable except in so far as the desirability of taking such a royal road to cognitive performance.

Human enhancement has already begun; the thin end of the wedge of transhumanism has already been driven into the crooked timber of humanity. [15] Any attempt to circumscribe further development cannot but appear arbitrary—at least to some—and the more that political regimes or social pressure are mobilized to enforce an arbitrary interdiction of development, the stronger the reaction against interdiction and prohibition will be. In this context it will be easy to frame human enhancement as an expression of individual liberty, though moral arguments will also be made for interdiction and prohibition—as we well know from the range of prohibitions presently maintained by our society.

While we can already see the first signs of an emerging transhumanist ideology that views the elimination of human limitations as a moral good, we can also see the first signs of an anti-transhumanist ideology that celebrates human limitations and views their elimination with a kind of moral horror. While we have accepted the use of glasses to correct vision, pacemakers to correct irregular heartbeat, cochlear implants to restore hearing, at some point we cross a threshold that the greater part of humanity is unwilling to cross, and human enhancements (or even restorations to full functionality) are viewed as morally unacceptable. The implied sorites paradox as to where humanity ends and transhumanity begins is, however, a temporary stage in our moral evolution.

Well-intentioned opposition to transhumanism will eventually paint itself into too narrow a corner from which it will not be able to extricate itself, first by creating a kind of secular theology that debates the minutiae of what it means to be “truly” human—it is easy to imagine a scholasticism that parses the human condition down to its finest details and debates what constitutes a “real” or “genuine” human being (absolute humanism in contradistinction to absolute transhumanism)—and secondly by attempting to fix human biology at its present stage of development. [16] One might even imagine a dystopian totalitarian political regime attempting to enforce the Hardy-Weinberg equilibrium and so bring human evolution to an end, institutionalizing allele frequencies at their present level in the human population and by selective breeding attempting not to produce a “better” human being but rather to produce a “genuine” human being, utterly free of the taint of having been the result of engineering—a result paradoxically only possible through population engineering.

5. Transhumanism is not One, but Many

When the future contingencies of history yet-to-be will eventually compromise the contingency of human finitude, the human response to this change in the human condition will be subtle, sophisticated, and, above all, it will be manifold. Transhumanism is not one, but many. There will not be one response, but many different responses, and each opportunity to confront a new dilemma will mean that a new bifurcation opens up, with some taking one horn of the dilemma and the rest taking the other horn.

Transhumanism will initially be something only to be had by the very few at a very high price, but in the fullness of time it will be a choice that every individual will be forced to make. When every individual must choose for or against transhumanism, many individuals will make many different choices. Here we must distinguish between the specific limitations of individuals and classes of limitations (including their characteristic parameters) that limit all human beings. The variation of limitation across individuals has been a social problem throughout human history. Some individuals are more limited than others, some less limited than others, and these natural differences will invite both technological redress (social leveling) and technological facilitation (the maintenance of traditional social hierarchy).

In the meantime, the earliest bifurcations in our species will come to us in more intimate and familiar forms. Parents, in their doting solicitude of their children, including future children not yet born, who imagine the enhancement of their children through genetic engineering and biotechnology, are typically as naïve as futurists who rely solely on diachronic extrapolation for their predictions. A child who had been greatly enhanced and experiences disproportionate opportunity as a result, is very likely to utterly disregard his family, not to mention the traditions and beliefs of this family (which likely provided that family with its staple meanings and reason for existence, and ultimately reasons for enhancement), because he begins life so far in advance of them and develops from that point forward, so that there is very little in common between the enhanced child and the family of source. Sometimes the apple not only falls far from the tree, but also continues rolling once it hits the ground. Parents and children in these circumstances would likely be a profound disappointment to each other, and this familial disenchantment will open further social rifts.

6. Transhumanism implies Transspeciesism

In the spirit of synchrony in the attempt to see history whole it should be obvious that we cannot treat transhumanism in isolation, i.e., as only affecting human beings. That transhumanism is not one, but many, means that the technology of enhancement will not be confined to human beings. The enhancement of other species began with their domestication, although in this context “enhancement” means selective breeding of species to produce qualities desired by human beings, which might not be considered enhancement by the species in question. Enhancement is in the eye of the beholder.

Transhumanism implies transspeciesism [17], i.e., that any and all species might be enhanced through the reduction or elimination of limitations. We would expect this for our companion animals (some time ago I had already written a post on transcanidism), but we might also wish to enhance the species we hunt, in the interest of better sport—we could produce for ourselves the most dangerous game, more dangerous than anything nature has to offer.

As each species possesses a unique set of endowments, we can conceptualize the enhancement of other species along the same lines as that I have outlined for transhumanism, in terms of reflection principles, so that each species implies its trans-being absolute as an inaccessible telos that is a reflection of the absolute infinite, marking off a distinctive parameter space of being that is further reflected downward in embodied trans-beings.

In the consideration of the technological facilitation of our species and our future it is not uncommon to skip ahead to the point at which embodiment becomes irrelevant, or at least marginal, but I want to linger for a moment on our relationship to other terrestrial species. The bare possibility of making the transition from biocentric civilization to post-biological civilization does not entail the actualization of that possibility—at least, not immediately. We are likely to maintain a great many naturally occurring biological species simply because we want them to remain a part of our civilization, whether for companionship or for food. While technological advances may eventually make food irrelevant in theory, in fact almost no one will want to give up the pleasures of cooking and eating. Food has a ritual if not a sacral place in human experience (much as does the concretely embodied home) and will be maintained in some contexts simply for this ritual comfort, while initially only a small minority adopts new rituals and displaces sacrality elsewhere. In so far as a ritual is an opportunity to participate in a myth [18], ritual meals will allow our distant descendents to participate in the traditional mythology of terrestrial humanity.

Each biome into which human beings inserted themselves during our planetary diaspora out of our African origins has made available a unique cohort of species, some of which have been domesticated and the fates of which have thus become tied to human beings and their civilization (no less than our fate is joined to theirs). Terrestrial food production involves this tightly-coupled cohort of co-evolving species dependent upon one another as a consequence of domestication (which latter formulation would constitute a biologically minimalist conception of civilization). This species cohort varies according to endemic species, topography, and climatic conditions—in the Americas we find the “three sisters,” potatoes, and bison, in southeast Asia tropical fruit, rice, and water buffalo, in the Arabian peninsula fava beans, dates, and chicken, in Africa sorghum, taro, yam, and Ankole longhorn—with the invariant being the participation of human beings.

Thus each region of Earth not only possesses a cultural diversity of civilizations, but also a biological diversity of civilizations, each of which may be defined in terms of the unique cohort of tightly-coupled co-evolving species. To date, this process has been an exclusively terrestrial one, but when cohorts of species representative of terrestrial civilizations leave Earth and establish themselves in other environments, the same principles will be iterated at higher orders of magnitude. And when human beings become transhuman this coevolutionary cohort will not simply vanish, but will change even as human beings change.

While the industrial revolution entirely marginalized food production as a sector of the economy, even given a biotechnological revolution that would, in theory, allow for biology to be entirely marginalized in human experience, that marginalization will not follow automatically, because human beings are biologically embodied, many identify with this embodiment, and many will continue to maintain a strong sentimental relationship to embodiment long after embodiment is no longer strictly necessary and becomes entirely volunaristic.

An extraordinarily long period of time will likely be required for Earth-originating intelligence to largely (much less entirely) separate itself from its biological origins, initially by making the transition from a biocentric civilization to a biologically marginal civilization, and then eventually taking leave even of that biologically marginalized fragment. It may require the entirety of the Stelliferous Era for the development of biocentric civilization to run its course, to leave us at the beginning the Degenerate Era only when our descendents are at long last prepared to make the transition to post-biological civilization. Even after experience can be exhaustively emulated in a virtual context, and ordinary experience cannot be differentiated from virtual experience by any objective, quantifiable measure, there will yet remain those who not only insist upon the authenticity of embodied experience, but who also insist that there is a subtle qualitative difference between embodied and virtual experience.

The advent of post-biocentric civilization would mean the end of civilization defined in terms of a co-evolutionary cohort of species, but the advent of transhumanism would mean the adaptive radiation, and therefore the speciation, of humanity, which would mean a potentially dramatic expansion of the coevolutionary cohort of species, to include not only many post-human descendents, but also post-natural species of every phyla. The technology that would enable transhumanism would also enable the technologically-driven adaptive radiation of other species. It seems likely that the cluster of biological enhancement technologies would result in an expansion of the coevolutionary cohort of species. Much as the industrial revolution expanded biocentric civilization to include extinct species (in the form of fossil fuels), biotechnology may extend biocentric civilization to artificial species. Before the narrowing of our civilization down to a sole technological implementation, there will come a great expansion of biocentric civilization facilitated by transhuman technologies.

transhuman adaptive radiation 2

7. Existential ends are not indifferent to technological means

Transhumanism will have a strongly selective effect. After a few generations (and generations will take much longer to elapse given the technologies of transhumanism) those who choose to avoid all enhancement will represent an increasingly small proportion of the population, and their genes will be consequently less frequently represented in the gene pool. The human condition will repeatedly bifurcate as individuals face more choices and more sophisticated choices: how much, to what degree and in what way, an individual might change his mind or body. Depending upon the resources that are available, and depending upon what technologies of transhumanism prove to be robust and effective—that is to say, depending upon contingencies not yet known—the human condition may do considerably more than bifurcate, it may embark upon a technologically enabled and accelerated adaptive radiation throughout the cosmos.

The argument that I have made in regard to the unknowns of technological development when it comes to the engineering success or failure of particular spacefaring technologies (cf. How We Get There Matters) also applies to the engineering success or failure of particular transhuman technologies, i.e., technologies of human enhancement. How exactly we become transhuman matters. Just as it matters how we travel in space, because the design, production, and use of particular technologies will shape the economic infrastructure and industrial base of that civilization that employs these technologies, so too how we become transhuman matters because the technologies of transhumanism will shape the civilization that employs them, and the technologies will come to shape civilization in turn. Again, existential ends are not indifferent to the technological means by which these ends are attained.

We can make broad distinctions in classes of technologies and consequent distinctions in the civilizations integral with these technologies. It should be noted at this point that only industrial-technological civilization can be integral with technologies in this way—driving technologies and being driven in turn by them. Other forms of civilization, if they have a relation to technology, do not have a relationship to technology that defines the civilization, whereas industrial-technological civilization is defined by its relation to technology.

In so far as civilization is a social technology emergent from human intelligence (a principle that I have called civilization-intelligence covariance), the adaptive radiation that will be driven by the technologies of transhumanism will result in different forms of intelligence, which will mean in turn the adaptive radiation of civilization, as novel forms of intelligence give rise to novel forms of civilization. The particular social technologies of civilization—which among them can and which cannot be engineered into large-scale social organization and institutions—will matter. And, again, in so far as civilization is a co-evolutionary cohort of species, the proliferation of new species in the wake of transhumanism again points to an adaptive radiation of civilization.

8. The Great Voluntaristic Divergence: Peopling the Future

The Great Voluntaristic Divergence will come about when both biological and planetary constraints are overcome and agents have a free hand to shape their history as they will. When history arrives at a point of complexity and sophistication that pathways can diverge significantly, and history is no longer subject to the constraints that have defined it since its planetary origins, preventing its divergence, convergent evolution will begin to decrease while divergent evolution will increase.

Though the Great Voluntaristic Divergence represents the overtaking of contingent limitations by conscious choice (hence voluntaristic), transhuman adaptive radiation through the cosmos will not fly in the face of established evolutionary principles, but rather will exemplify what we know of adaptive radiation, albeit at an order of magnitude not previously realized in terrestrial history—a macroevolutionary adaptive radiation, if you will. Beyond the terrestrial biosphere, the principles of biology will continue to hold good, but in unprecedented ways. That we have at times mistaken contingent limitations on our biology for a kind of biological necessity may show up some of our initial misapprehensions, but once the fallacy has been identified as such, we will see adaptive radiation unfold on a cosmological scale.

For a sense of what biologists mean by adaptive radiation, here is a brief definition:

adaptive radiation: biologic evolution in a group of related species that is characterized by spreading into different environments and by divergence of structure. [19]

A longer and more detailed definition of adaptive radiation is to be found at Paleos as follows:

Adaptive radiation: the rapid expansion and diversification of a group of organisms as they fill unoccupied ecological niches, evolving into new species or sub-species; the classic example being Darwin’s finches. This occurs as a result of different populations becoming reproductively isolated from each other, usually by adapting to different environments. Radiations specifically to increase in taxonomic diversity or morphological disparity, due to adaptive change or the opening of ecospace, may affect one clade or many, and be rapid or gradual. The term can also be applied to larger groups of organisms, as in “the adaptive radiation of mammals” (see diagram below), although in this context it is perhaps better referred to as evolutionary radiation. Evolutionary radiation in this context refers to a larger scale radiation; whereas rapid radiation driven by a single lineage‘s adaptation to their environment is adaptive radiation proper. Adaptive and evolutionary radiations in this latter context follow mass-extinctions, as when during the early Cenozoic mammals and large flightless birds filled ecological roles previously occupied in the Mesozoic by dinosaurs.

Elsewhere I have said that astrobiology is island biogeography writ large. As we know from the example of Darwin’s finches, islands provide a particularly effective setting for speciation. The mechanisms of adaptive radiation are facilitated by an archipelago. On a much larger scale, the adaptive radiation of life in the cosmos will be driven by the range of conditions on an archipelago of habitable worlds, isolated like islands in the vast sea of interstellar space, more sterile even than the pelagic zones of terrestrial oceans.

Transhuman adaptive radiation will be an aspect of extraterrestrial dispersal vectors, both serving as a vector for the extraterrestrial dispersal of terrestrial species (which will radiate adaptively no less than humanity), and being driven further in turn by this dispersal of other terrestrial species. Each cohort of species that remains in biological proximity will coevolve while simultaneously radiating outward into the universe.

J. B. S. Haldane already explored some of these possibilities in his essay “Man’s Destiny” in his book Possible Worlds and other Papers (published in 1928), and in his 1963 lecture “Biological Possibilities for the Human Species in the Next Ten Thousand Years” [20] A more recent treatment of the same theme is to be found in Christopher Wills:

“As we spread to worlds that are very different from our own, the consequences for our evolution will be at least as profound as when our remote ancestors first ventured out of Africa. Will people living on other planets evolve into new species? Given sufficient isolation from the rest of us, we have no reason to suppose otherwise. Indeed, challenged by very different environments, they will probably become new species much more quickly than the millions of years that were required to engender the timid beginnings of speciation in the orangutans of Borneo and Sumatra. In short, the powers of natural selection that Darwin was the first to understand will certainly continue to shape our species. Here it is our task to try to glimpse the accelerating ways in which biological and cultural evolution will reinforce each other in the future, and to understand how this mutual interaction will allow us to survive the evolutionary challenges that we will face as we begin our spread through the universe.” [21]

Wills’ book is all about how human evolution, biological and cultural, far from having been arrested by the advent of civilization, has been accelerating as a direct result of civilization. To Wills’ concern for the accelerating evolution of human beings I would add the accelerating evolution of all species tied to human civilization, and to biological and cultural evolution noted in the above quote, we might wish to add technological evolution. When technological evolution becomes indistinguishable from biological and cultural evolution, i.e., after transhumanism, we will understand that biology and technology will be coextensive, without any need to make note of it.

I noted above the transhuman adaptive radiation will have a selective effect. I previously addressed this in The Human Future in Space, where I wrote:

“Other planetary bodies can be adapted for human habitation, and we can build structures in space that imitate gravity. However, it is worth noting that health will be an important factor for those leaving Earth to live elsewhere in the cosmos. Just as the individuals who go into space will be self-selected by their desire to live away from Earth, they will also be physically selected. Living in micro-gravity, low gravity, high gravity or simulated gravity environments will be strongly selective. There may be individuals who desire to live in these other environments, but who find that they are physical incapacitated by them. But due to human genetic variability, there will be some individuals who happened to be well-adapted to differing gravity environments. Such individuals will be favored in the expansion into space and they will pass on their genetic legacy to their children. Humanity will evolve under extraterrestrial selection pressures.”

These extraterrestrial selection pressures will be distinct in distinct environments, and so will lead to adaptive radiation among isolated populations, and populations will be more isolated across the gulfs of space than they were ever isolated by geographical barriers on Earth. To the technologically-driven selection pressures of transhumanism, then can be added the unprecedented selection pressures of alien worlds and artificial environments. And it doesn’t end there.

Because human beings are not only physical beings but also cultural beings, there are cultural forms of adaptation. These cultural forms of adaptation are more familiar and more obvious to us from our terrestrial experience than biological adaptation, which takes place over a biological time scale that conceals in plain sight the change that cannot be observed over a period as short as a human life span. Cultural adaptation is what we today call diversity, and an extreme diversity of cultural adaptations characterizes humanity’s inhabitation of Earth, as it was by way of behavioral adaptation that human beings were able to expand on a planetary scale and to inhabit every biome.

The sociocultural radiation of transhuman beings will also take place on an unprecedented scale coinciding with the possibilities opened up by the energy and material resources of a practically inexhaustible universe. Thus there is, in addition, the possibility of an abstract radiation into artificial environments—a radiation that transhuman beings would be especially well placed to effect. The technium is an artificial environment into which human beings could radiate, and which would expand and proliferate in that radiation.

9. Conclusion: Transcending Planetary Limitations

A viable spacefaring civilization, as we see, cannot be separated from the evolution of the agents of the spacefaring civilization; both are mechanisms of history considered on the largest scale. Transhumanism, like spacefaring, is not an end itself. Like any evolutionary development, as in technology no less than in biology, everything is a transitional form. In a famous passage of Thus Spake Zarathustra Nietzsche had his prophet deliver himself of the utterance: “Man is a rope stretched between animal and superman—a rope stretched over an abyss.” [22] Today we might rather say, “Man is a rope stretched between animal and transhumanity—a rope stretched over an abyss,” and then go on to note that the abyss is existential risk.

This does not go far enough. Transhumanity is a paradigm of sentient-intelligent being of the Stelliferous Era, still ensconced within the paradigm of civilizations of the Stelliferous Era. We must transcend this paradigm as well. Earth and its biosphere are a rope stretched over a cosmological abyss. Civilization is a rope stretched between prehistory and our life in the cosmos. Civilization is perhaps the highest stage of terrestrial development, but that does not mean there are no further developments to come—those further developments being what I have elsewhere called “post-civilizational successor institutions.” What the Cambrian revolution was to life on Earth, the great voluntaristic divergence will be for the cosmos at large. And if it is not terrestrial life that goes on to this destiny, we can hope that life originating from some other biosphere fulfills this function, whether according to evolutionary or technological time scales.

The transcending of planetary limitations is of a piece with transcending our biological limitations: it is a necessary step toward cosmic viability, but it is not the final step. On the contrary, both the transcendence of human limitations and planetary limitations may be considered the first step toward the cosmic viability of life originating in a planetary biosphere. Moreover, these two forms of transcendence are essentially one, as the peculiar limitations of human beings are a function of the terrestrial history of our species; the transcendence of human limitations is simply another planetary limitation to overcome, one limitation among many. This process of transcendence admits of no boundary and converges on infinite time.

In Who will read the Encyclopedia Galactica? I already began to suggest these themes of infinite history, and the possibility of beings with an infinite lifespan who could quite literally think the infinite thoughts that are denied human beings as we exist (and think) today. Dyson’s eternal intelligences are the distant descendents of the transhuman beings we see in our own future; or, to see it from a different perspective, the transhuman beings of our future, that some may perhaps see as the fulfillment of technological maturity, are a bridge over an abyss, and on the other side of the abyss are Dyson’s eternal intelligences.

Finally, in regard to an infinite future, it should be noted that the relation of absolute transhumanism to the absolute infinite by way of the reflection principle will also hold of infinitistically conceived history and cosmology in relation to the absolute infinite by way of the reflection principle: all that I have suggested here in relation to transhumanism and the reflection principle applies, mutatis mutandis, to infinitistic historiography and infinitistic cosmology. We will of course ask ourselves whether this infinite historiography is a reflection of a temporal absolute (an absolute temporal infinity, itself a reflection of the absolute infinite), and, if you like to think of a temporal absolute as the eternal, you have arrived at the Platonic formulation that time is the moving image of eternity. [23]

[1] It has become fashionable in some quarters to dismiss human experience and its apparent unity as a “user illusion,” but if it is an illusion, it is a robust and persistent illusion that can be studied in some degree of detail without the loss of its unity. Indeed, it is more difficult for most of us to imagine our experience as fragmented than as unified, simply because we have never experienced anything other than the unified stream of conscious experience, however heavy-handedly our brains must intervene in order to impose this order on experience—but this cognitive component, too, is another contributing element to the final synthesis of experience. There are, of course, many forms of pathological experience, and the books of Oliver Sacks are replete with remarkable anecdotes of individuals who fail to experience the world as most of us do. The existence of these exceptions in no sense disproves the rule.

[2] If the transition is a transition to the realization of some existential risk—extinction, permanent stagnation, flawed realization, or subsequent ruination—rather than to a viable spacefaring future, the role of the agents in this transition is no less interesting. Indeed, it could be argued that it will be the experience of the agents of history, collectively and individually, that will determine the overall course of history when it comes to the bifurcation between the viability or ultimate non-viability of civilization.

[3] I am not making the claim that this is the only way to define transhumanism, but only that it is an interesting and potentially fruitful way of defining transhumanism, as I will attempt to demonstrate below. Transhumanism might also be defined in terms of humanity beyond the prediction wall. This, too, might be a fruitful approach to transhumanism, but I will reserve its exposition for another time.

[7] The reader who wishes to learn more about the theory of transfinite numbers may profitably consult any number of textbooks on set theory. A good introduction is Everything and More: A Compact History of Infinity by David Foster Wallace—yes, the novelist.

[8] In regard to any human faculty converging upon the infinite, there is a passage from Gödel that I have quoted many times (cf. Gödel’s Lesson for Geopolitics, Evolutionary Transcendence, and Addendum on Technological Unemployment): “Turing… gives an argument which is supposed to show that mental procedures cannot go beyond mechanical procedures. However, this argument is inconclusive. What Turing disregards completely is the fact that mind, in its use, is not static, but is constantly developing, i.e., that we understand abstract terms more and more precisely as we go on using them, and that more and more abstract terms enter the sphere of our understanding. There may exist systematic methods of actualizing this development, which could form part of the procedure. Therefore, although at each stage the number and precision of the abstract terms at our disposal may be finite, both (and, therefore, also Turing’s number of distinguishable states of mind) may converge toward infinity in the course of the application of the procedure.” (“Some remarks on the undecidability results,” Italics in original, in Gödel, Kurt, Collected Works, Volume II, Publications 1938-1974, New York and Oxford: Oxford University Press, 1990, p. 306) In this way, any human faculty that transcends its limitations might be said to converge toward infinity.

[9] Azriel Lévy “Principles of reflection in axiomatic set theory” Fundamenta Mathematicae, T. XLIX, 1960, pp. 1-10. Lévy cites a paper by Tarski and Vaught, “Arithmetical extensions of relational systems,” Compositio Mathematica, 13 (1957), pp. 81-102, noting that reflection principles are related to arithmetical equivalence and arithmetical extension. This line of thought emerges out of model theory, and the Löwenheim-Skolem theorem is a continual point of reference. On the Löwenheim-Skolem theorem and model theory cf. Badesa’s book The Birth of Model Theory: “Today, we use the name Löwenheim-Skolem theorem to refer to all the theorems that guarantee that if a set of formulas has a model of a particular cardinality, it also has a model of some other cardinality.” (Calixto Badesa, The Birth of Model Theory: Löwenheim’s Theorem in the Frame of the Theory of Relatives, Princeton and Oxford: Princeton University Press, 2004, p. 143)

[10] On alternative formulations cf. Hilary Putnam, Philosophy of Logic, New York: Harper & Row, 1971: “One group of questions which I might have considered has to do with the existence of what I might call ‘equivalent constructions’ in mathematics. For example, numbers can be constructed from sets in more than one way. Moreover, the notion of set is not the only notion which can be taken as basic; we have already indicated that predicative set theory, at least, is in some sense intertranslatable with talk of formulas and truth; and even the impredicative notion of set admits of various equivalents: for example, instead of identifying functions with certain sets, as I did, I might have identified sets with certain functions. My own view is that none of these approaches should be regarded as ‘more true’ than any other; the realm of mathematical fact admits of many ‘equivalent descriptions’: but clearly a whole essay could have been devoted to this.” (pp. 75-76)

[11] Hao Wang, A Logical Journey: From Gödel to Philosophy, p. 280. In Wang’s books it is nearly impossible to tell where Wang leaves off and Gödel begins, as Wang’s books are assembled from notes he took based on conversations with Gödel, so that many of the ideas are Gödel’s, but expressed in Wang’s terms (much like Ludwig Landgrebe’s reworking of Husserl’s notes in the manuscript that became Experience and Judgment). The closure principle, in turn, is defined by Wang as follows: “If the universe of sets is closed with respect to certain operations, there exists a set that is similarly closed. This implies, for example, the existence of inaccessible cardinals and of inaccessible cardinals equal to their index as inaccessible cardinals.” (Wang, Ibid.)

[12] Tiles, Mary, The Philosophy of Set Theory: An Historical Introduction to Cantor’s Paradise, Oxford: Basil Blackwell, 1991, p. 158. “ZF” is an abbreviation for “Zermelo Fraenkel” which identifies by the names of the responsible mathematicians the most widely familiar axiomatization of set theory.

[13] The comprehension principle is an idea from naïve set theory that any property defines a set. The Russell paradox is that it is impossible to form a set that is the set of all sets not members of themselves. In order to avoid such contradictions, limitations are placed on the comprehension principle, as, for example, with the separation axiom (also called the subset axiom). D. C. Makinson characterizes the separation axiom as follows: “…every property marks off a subset of any given set. In other words, given any property expressible in the notation of our system of set theory, and any given set, there is a set whose elements are exactly the elements of the first set that possess the property.” (Topics in Modern Logic, London: Methuen & Co Ltd, 1973, p. 81) Different formalizations of set theory achieve this end by different means. (One way to narrate the history of set theory would be to present it as the many and different attempts to limit comprehension while retaining as many sets as possible).

[16] If human beings were to arrest human evolution while the remainder of the biosphere continued to evolve, eventually these two biologies would diverge and human beings would no longer be fit to live on Earth. Hence the dystopian scenario in the next sentence would have to be extended to the whole of the biosphere if it were to function over the long term.

[17] A more felicitous rendering might employ a single “s”: transpeciesism, as in “wherever” in which one “e” is eliminated in the conjunction. Alternatively, one might employ a hyphenated form: trans-speciesism.

Dyson’s eternal intelligences – where are they? If none have been created so far, perhaps one’s hubris is undone. At least, in an eternity of time a Boltzmann brain should be seen? But so far no where it seems?

Adam May 29, 2015 at 18:20

William Blight,
Dyson’s “Eternal Intelligences” are postulated beings of an infinite future in an Open Universe. You can find his physical argument for their possible existence here:

Time Without End: Physics & Biology in an Open Universe

Of course, they may not be possible since there’s evidence that the Universe might evolve into a DeSitter state, with finite pockets of matter isolated by the cosmological constant.

James Stilwell May 29, 2015 at 18:52

In the movie AI: Artificial Intelligence, Kubrick suggested that humanity will last only a brief moment in evolutionary time, destined to be replaced by the artilects…metal beings who do not count time as humans do…I wish somebody would make a convincing argument otherwise…

“On a much larger scale, the adaptive radiation of life in the cosmos will be driven by the range of conditions on an archipelago of habitable worlds, isolated like islands in the vast sea of interstellar space, more sterile even than the pelagic zones of terrestrial oceans. “

This may be a problem as we require a microbiome to live. Sterile worlds will need to be populated by the bugs we need (and phages needed to keep these bugs in check). I don’t know how easy or difficult this will be in the cosmos.

As we speciate, might we not compete, leaving one sole species, just as H sapiens sapiens has eliminate all other hominid species on Earth? This may happen quite early in the radiation, unless time and space can prove a viable separator of populations.

Abelard Lindsey May 29, 2015 at 22:19

Although I have my doubts about the specific technologies that advocates of transhumanism expect to show up in the coming decades, I am 100% in agreement with the objectives of transhumanism in the philosophical context that the purpose of intelligent beings is always to strive to become more, and that technology is the tool to enable such. To me, transhumanism and space colonization are inseparable. I simply fail to comprehend how some advocates of space colonization (such as Robert Zubrin) can express hostility towards the tenets and objectives of transhumanism.

It has been utterly obvious to me since the 1980’s that some flavor of transhumanism and extropian positivism will be the dominant meme of humanity (or transhumanity) as we spread through out the galaxy in the long-term future.

When it comes down to ways to colonise “difficult” planets, we can go either way – machine embodiments of ourselves or biological modifications of our genome – or indeed some combination of the two. I think we’ll take both paths at the same time. The richness and complexity afforded by genomic modification seems to favour this self-engineering approach over an all-metal AI.

Nick Nielsen May 30, 2015 at 18:15

RE: William Blight, Adam

Adam has already posted a link to Dyson’s paper on eternal intelligences. I discussed this idea extensively in my previous Centauri Dreams post, Who will read the Encyclopedia Galactica? I suggested there that eternal intelligences will read the Encyclopedia Galactica, as only they would have the complete record of civilizations of the Stelliferous Era.

As Adam points out, there are scenarios of cosmic evolution in which eternal intelligences could not come about. There are also many critiques of the very idea of eternal intelligences, apart from their compatibility with a future state of the universe. Dyson was very explicit in his paper about choosing to write about a scenario in which there was a long term possibility for the survival of intelligence in the universe. If some form of intelligence does not survive, then the future universe is not observed, thus a future state of the universe falls outside the class of universes that are observable.

Nick Nielsen May 30, 2015 at 18:32

RE: James Stilwell

I believe the term “artilect” is due to (or at least associated with) Hugo de Garis rather than the AI: Artificial Intelligence film, which is by Spielberg rather than Kubrik.

The Childhood’s End scenario is similar in some respects to what John Smart called The Transcension Hypothesis.

Some people have a great enthusiasm for these potential futures, and some regard them as a moral horror. Since you view the Childhood’s End scenario as “something worse” than human beings succeeded by artificial descendants, I would guess that you are closer to the moral horror end of the continuum. But this is precisely one of the points I was trying to make above: different individuals have different responses to change, and as a consequence they will choose different paths to different futures.

When our civilization is eventually extraterrestrialized (which is the only possible form of civilization viable in the long term), the terrestrial constraints that keep us on more-or-less one path to the future will be eliminated, and we will then see the Great Voluntaristic Divergence, in which the difference choices of different individuals play out on a cosmic scale, and they will not have to all play out on and compete for a single planet.

Nick Nielsen May 30, 2015 at 19:21

RE: Alex Tolley

Precisely because we require a micro- (or larger) biome in which to live as the organic beings that we are, we will have to take with us all the species we require in order to survive, and all the species required for the survival of the species we require, and so on. Space exploration to date has been a highly sterile undertaking, but any long-term, large scale expansion into the universe will be as much about other terrestrial species as it will be about ourselves. I have addressed this question on several occasions, as in my Centauri Dreams post Extraterrestrial Dispersal Vectors. Thus when we arrive at other sterile planets, we will have the bugs we need with us already, and, if we are smart, we will carry as complete a record of the terrestrial biosphere as we can bring along, including the species that we have sought to extirpate, such as weeds and competing predators.

“As we speciate, might we not compete, leaving one sole species, just as H sapiens sapiens has eliminated all other hominid species on Earth?”

It is possible, but I think that the universe is sufficiently large that competition would have to wait until after the observable universe had been completely seeded with life. On this time scale, adaptive radiation would already have taken place, species would have diverged quire considerably from their terrestrial origins, and for these adaptively radiated human descendants to compete leaving only a sole successor species would take even longer — so long, perhaps, that the Stelliferous Era would come to an end before that could happen. So I do not say that I categorically disagree with your suggestion, and, while I think it is unlikely, I would say that the matter requires further study.

Project Studio May 30, 2015 at 23:30

I think that in the context of this article ‘astrobiology is island biogeography writ large) human nature can be encapsulated in the quote “O brave new world, That has such people in’t.”

Our naiivte in the face of the complexity of factors that will influence future human evolution is comparable to the ease with which mathematicians apply the human concept of larger and greater to infinite sets of numbers that are merely more or less “dense” in a fully abstract space.

While I applaud the daring foray of thought projected into the future, the academic couching of transhumanism within set theory and Latin phraseology tends I think to add unnecessary abstraction and obscures the point I think the article is trying to make that the potentials of transhumanism are multifold and resplendent. The limitations the article places on absolute transhumanism are also unnecessary as omnipotence and omniscience in their practical application would also have a context which narrows to remove the possibility of paradox, and broadens to include new scope beyond the transcended limits.
I now leave this thread with dreams of electric mutton and an intention to study dead languages in the future. once again, a thought provoking article.

Nick Nielsen May 31, 2015 at 2:55

RE: Abelard Lindsey

I don’t see transhumanism as any kind of objective at all, but simply a consequence of evolution speeded up by technology. Transhumanism is coming upon us much as industrialization came upon us — as a result of millions of individual decisions without any grand plan.

I agree that, “transhumanism and space colonization are inseparable,” though there are different senses in which they could be said to be inseparable. Some posit that transhumanism is a necessary prerequisite to adaptation to space travel. If you suggest that human beings can construct artificial habitats for themselves as travel just as they are, this particular inseparability paradigm is challenged (I never seem to make much headway in these debates).

Similarly, some posit that space travel will require such long periods of time that it will require suspended animation, longevity, or reconstitution to get human beings to other worlds. If you suggest that alternative forms of propulsion might obviate the need for long voyage times, this paradigm of inseparability is challenged.

The inseparability for which I am arguing is that the kind of civilization we have (which I call industrial-technological civilization) regularly produces technological progress, and this technological progress will be applied synchronically both to space travel and human life. Hence the need for a synchronic understanding of history, as suggested in the opening paragraphs of this essay.

Nick Nielsen May 31, 2015 at 4:29

RE: Andrew Palfreyman

“I think we’ll take both paths at the same time.” That’s the point. The future is large enough to contain all these possibilities and more. Arguing for an exclusively human future or an exclusively machine future is too narrow, as we will likely have both and everything in between as well.

Brett Bellmore May 31, 2015 at 8:31

“The thoughtful critics of this attitude assume that most individuals eventually rise to a level of maturity that allows them to accept their mortality, and assert that if human beings were given a life freed of biological necessities that they would not know what to do with themselves, and, like the Cumaean Sibyl, would wish for a death that does not come.”

The term for this is, “sour grapes”.

Jer May 31, 2015 at 9:30

A fascinating read and an optimistic (even inspiring) vision.
I would argue that our future definitions, boundaries, and paths into transhumanism will be more defined by our inter-relationships with others – transhumanist aspirants and others that we interact with (and depend upon, perhaps) frequently. I think the article, with all due respect, effectively neglected the communal aspect (different than ‘within our species’ as a whole). It will be the ‘bouncing off’ and sharing and communal aspirations that will focus, propel, and enrich us the most. If we are essentially a mind CPU, sensors to gather info, and mechanisms to influence our surroundings -and- the entire purpose of those who aspire is to engage and consume (and thus become) complexity (knowledge, experience, ingenuity, etc.) — than accumulating the same from others would be the most efficient way to continue along this path to increasing complexity (perhaps a good quantification of transhumanism – units of complexity). In our accumulation of this shared knowledge we become a hybridized self. Is this a limitation or accelerator? Accelerator. For how ever fast we could accumulate complexity, we can accumulate it faster by the efforts of others who have also accumulated complexity. It would be interesting to consider transhumanist families, communities, and networks – in how they shape, influence, and direct the speed, direction, and potential of the individual transhumanist. Would the most advanced transhumanist (perhaps measured in units of complexity) be more borg-like or Q-like after many iterations of ‘upgrade’. I would say Borg (perhaps without the predatorial intentions).

@Nick Nielsen
“The argument that I have made in regard to the unknowns of technological development when it comes to the engineering success or failure of particular space faring technologies (cf. How We Get There Matters)”

I think the “How We get There Matters” is important for speciation. Relatively few world ships and abundant inhabitable worlds will facilitate adaptive (or technological) radiation. OTOH, few inhabitable worlds and small FTL ships will reduce the effective separation of populations. However, if the possible adaptive radiation options are fully utilized, machine or robotic embodiment will increase habitats, while restrictions to biological, only core human forms will reduce them.

On Earth, if habitats are reconnected (e.g. land masses combine, or land bridges form during ice ages) then previously separated will compete for the same resources they both need. Again, how easy interstellar travel is will determine how separated worlds will remain to allow species to remain safely separate. FTL travel may make all worlds be part of a joined habitat and therefore potentially allowing competition and eventual domination by a species.

Even without FTL, calculations have shown that von Neumann replicators can occupy all stars within a million years, about the length of time most Earth species exist. This suggests that an aggressive species could compete with all other species and dominate.

Should there be an extended period of space habitat building in the solar system before interstellar voyages are undertaken, the likelihood that different human species can co-exist or not might be tested.

RE: Project Studio

Brave new world, indeed! The isolated Miranda who speaks these words was a product of an insular environment (Prospero and his daughter are quite literally marooned on an island), and when she encounters other human beings, of which she had, up to that time, known nothing, she is astonished by the revelation.

“The limitations the article places on absolute transhumanism are also unnecessary as omnipotence and omniscience in their practical application would also have a context which narrows to remove the possibility of paradox, and broadens to include new scope beyond the transcended limits.”

I would love to see a detailed exposition of this thesis.

Brian May 31, 2015 at 21:52

Who decides what mankind becomes? Not you or me, not the engineers building the technology, but whoever pays for it. Not sure I consider that desirable even if I found any emerging technology hyped by the modern transhumanist movement promising.

RE: Jer

I assumed in the above, without making it explicit, that part of the Great Voluntaristic Divergence will be communities of different sizes going off on their own. That is to say, diverging from centers of civilization will be anything from single individuals to entire civilizations liberated from planetary constraints and taking up whatever way of life seems best to them.

I will admit without hesitation or embarrassment to a vision of a spacefaring future in which individuals and families and communities can get into a starships and lose themselves in the cosmos — a vision no doubt fueled by my youthful reading of every Heinlein juvenile novel, as well as a lot of Poul Anderson, Andre Norton, and others.

Recent futurism has distanced itself from the expansionist (and individualist) paradigm, and I think that there are sociological reasons that explain this. The spacefaring future envision in fiction by the authors mentioned above and in prose in the Collier’s space program and the O’Neill space program, etc., was the occasion of profound disappointment once government funding for the Space Race declined with détente. The idea of zipping about the universe in spaceships, exploring and getting into adventures, came to seem naïve and, quite literally, too good to be true. But don’t expect anyone to admit that this individualistic future is too good to be true, because that would be (as Brett Bellmore pointed out above in relation to transhuman longevity) sour grapes.

Quite a bit (more than we would like to admit) of our contemporary paradigm of what constitutes the good life and a idealistic society for human beings has been shaped by sour grapes as a result of planetary constraints on the development of civilization. If we don’t stop striving, those grapes will eventually come within our reach and we will find them sweet beyond imagining.

And then one of the transhumans chooses to exert control over all else by means of becoming an accelerating AI…

ljk June 1, 2015 at 8:28

Yes, Hugo de Garis coined the term Artilect to describe an artificial intellect, also known as an AI. I prefer the term Artilect and use it whenever the need arises.

Unlike many other experts on this subject, both real and self-anointed, de Garis sees problems from the coming of the Artilects more from human reactions to them rather than any real threat from the new intellect on the block themselves:

Artilects will likely be the next major step in the evolution of intelligence coming from Earth. I can imagine how most humans will feel about their descendants not being merely some larger-brained version of themselves.

They should be proud and impressed that we could go from swinging in trees just a few million years ago to creating such beings, but right now I can only see a largely negative and fearful reaction, much as people often do when it comes to the idea of advanced ETI, especially if it has plans to visit Earth.

Of course others go to the opposite extreme and view both ETI and Artilects as the saviors of humanity, but I wonder if there is any “saving” done upon our species it will be indirectly. I think Artilects will have much bigger and far more interesting things to do than hang around and make a few improvements to their nurseries just to make their nannies temporarily happy.

Harold June 1, 2015 at 9:31

Alex Toley,

Even with FTL ships, I don’t think competition between planets would produce a singular, fittest form. Transhuman technologies promise to generate a breadth of speciation more similar to the range of all current lifeforms on Earth than the range of hominids. With so wide a range of forms competition will tend to push forms toward new environmental niches. As well, I would describe a biological/semi-biological entity with access to technology as having a similar form to any other biological/ semi-biological entity with access to technology. Even if competition over resources commonly occurs, technology will allow individual forms to evolve independently of that competition.

That is not to say there won’t be a fittest form, but I think that form will evolve as it competes against finitudes such as mortality and data storage.


I agree. I don’t think the term transhumanism will survive the evolution of transhumanism, but will be replaced by something like “trans limits of individual experience”. The most valuable resource to these beings may very well be unique perspectives that they can not generate themselves.

ole burde June 1, 2015 at 15:37

Whatever the the future will bring for human beings , it will somehow be a logic continuation of biologic evolution and its extention into the virtual evolution of multiple human cultures.
In short , the basic rules of evolution is not going to change very much , even if we invent a certain benchmark from wich any further evolution will be defined as ”transhumanism” …
Some of us like to believe a unified global culture is just around the corner , but this does not fit very well with observed reality , where fundamental cultural differences in many ways seem to be growing ever stronger .
This , ofcourse fits very well with a basic tool of evolution called ”variability” . If one human culture fails to exploit the benefits of genetic engineering , another culture will exploit this failure to increase its strength and territory .
Lets say a certain leading culture would ban any experimentation with human genetics for ”moral ” reasons . As time passes by , certain un-exploited bennefits becomes bigger , and the cost of realizing them grows smaller . Before or later the proces we call evolution will short-circuit this potential , and when this happens it will not be acording to a specifik human-style ”plan” we can recognize , it is more likely to be predictable as a direct continuation of ”History” , or as close to an objective description of history as we can get .

Alex Tolley June 1, 2015 at 23:02

@Harold – Even with FTL ships, I don’t think competition between planets would produce a singular, fittest form

If we use the evolutionary model on Earth, then speciation requires populations to be isolated from each other. This was the model that I was invoking. However I also accept that technological speciation ,ay not need that condition, that it could be engineered. For example, it might be possible to engineer a population of humans that use a different genetic code or DNA bases. This would result in a separate population living amongst teh existing human population. Similarly, machine embodiment would do teh same.

Whether they compete or not, and whether that competition results in one species dominating or even making the losers extinct is unknown. For any randomly selected post-human species to increase their odds of survival would require finding a habitat that is isolated from other post-human species whatever their form. Slow, infrequent, worldships would most likely ensure such isolation, as this most mimics habitat isolation letting teh new species continue to evolve with a low probability of competition from other post-human species.@Harold – if very different human species are to live in teh same environment, e.g.

“It is an obvious, and unforgivable, oversimplification to assume that everyone wants to live forever or that no one really wants to live forever.”

Without stated dramatics, the decision is being decided for me in the relatively near future. I had the opportunity and privilege of spending a year as an intern social worker/counselor in a hospice organization. My assigned contacts among the clients were actually living more intensively than ever before in their lives. In what we consider spiritual matters, if ten people enter into a discussion, there will be at least 15 distinct positions presented. Dying is truly a very personal, individual and private matter. But there were none, in the last days, who believed that life would end. My spiritual beliefs are far from orthodox, but as I contemplate the future, I have concluded, as they did, that life, undefined and transcendental, does not end. I have no fear, no regrets, and great anticipation for an infinite future. If I could rebuild this worn body, with improvements, perhaps I would take another trip around the block. Probably not: I am quite curious about the next leg of this voyage of profound discovery. That is just my take on the matter.

ole burde June 2, 2015 at 2:38

So , is the idea of Transhumanism just a smart way to get around the painfull and explosive debate about Human Genetic Engeneering ?
On the one hand the core issues are identical , but on the other hand Transhumanism is a much wider concept .
Is it possibel to imagine a future where a subspecies of humans are designed for life in space , or elsewhere, while at the same time a total ban om human genetic engineering is enforced on earth ?
Is it possible for the human species to expand into space without using the tool of human genetic engineering ?
Not very propable , and thats why I think the isue of Human Genetic engeneering should be faced Head-On , whereever there is a winnable argument , such as the present talk of ” babies with three parents” .

ljk June 2, 2015 at 12:16

Humans already spend lots of money and resources on improving themselves, especially their appearances. It is all done quite voluntarily, unless you count societal and peer pressure as being big factors in such desires.

As science and technology advance so that people can really change their appearances, which will include their genders, issues with so-called genetic engineering will fall by the wayside in the name of looking and feeling good and making vast sums of money.

This may also extend into humans being modified to live on all sorts of alien worlds and environments, including space itself. The survival of the species will thus improve greatly. Space colonization as it currently stands with really expensive methods to recreate a terrestrial environment for a relative handful of unmodified people may not happen outside of a few token efforts otherwise.

How many people would want to live for decades underground or in a dome with no easy or quick way to return to Earth? Some I am sure but not as many as would like to think they could. Humans are still very much creatures of the plains and trees even though they are adaptable to degrees of variation (high mountainous regions, for example). But would this adaptability work as well if they have to live in a very restricted structure surrounded by an environment far more hostile than the worst places on Earth?

Brett Bellmore June 2, 2015 at 19:28

“. For example, it might be possible to engineer a population of humans that use a different genetic code or DNA bases. This would result in a separate population living amongst teh existing human population. Similarly, machine embodiment would do teh same.”

I think not. DNA is just a means of storing data. Technology can translate between storage schemes. With genetic engineering, in principle humans are interfertile with lichen. On a more abstract level, data processing schemes could be translated between biological and technological brains.

In isolation, you might get speciation, but it would have to be communications isolation, not just physical. More likely, what we’re going to see is a continuum of lifeforms. Any sustained speciation will be due to cultural isolation, not physical barriers.

Alex Tolley June 3, 2015 at 0:24

“With genetic engineering, in principle humans are interfertile with lichen. “

I think not. What possible viable offspring could result? You are confusing the fact that sequences of DNA can be inserted in highly disparate organisms and be functional, with viable offspring based on sharing 50% of their genomes. I think your are stretching the concept of species well beyond any limit that biologists would use.

“More likely, what we’re going to see is a continuum of lifeforms. Any sustained speciation will be due to cultural isolation, not physical barriers.”

What you are saying that just communication is enough to mingle population genetics. If so, then consider the consequences of a successful SETI contact in the next century, even if they are intelligent lichen. If you are correct, then technology effectively stops speciation in the universe, creating a vast spectrum of forms, which despite their physical differences can freely interbreed with any other through technology mediation.

Brett Bellmore June 3, 2015 at 18:55

Yes, that’s essentially it. Genetics are data, and deliberate data processing is vastly faster and more versatile than natural reproduction. The advent of genetic engineering is the end of natural evolution for any species that is subjected to it, as a practical matter.

And speciation is an aspect of natural evolution. Genetic engineering already crosses species boundaries, even phyla differences fall before it. Human genes get inserted into yeast. Yeast genes could be translated into humans, too, if we found some we liked.

But I don’t think this ends speciation. Speciation on Earth isn’t just based on genetic incompatibility. Speciation can arise and be sustained by differences in mating behavior, or preferred habitat.

Intelligent species could be caused and sustained by cultural factors. Just because you could mix your genes with the other, doesn’t mean that you will; Maybe your culture aims for something different from their’s.

Alex Tolley June 3, 2015 at 22:57

@Brett – the idea of the death of post-human speciation due to technology would be an interesting one to explore. It might even be subject to modeling.
Your points are well taken that we may no longer be subject to slow biological forces, and that the horizontal spread of “memes” might include technological gene transfer sufficient to overwhelm any slow evolution.

RE: Brian

“Who decides what mankind becomes? Not you or me, not the engineers building the technology, but whoever pays for it.”

There are strong and undeniable economic motives running through our history, and especially in those commercially-oriented civilizations such as ours… however, economic motives are not the sole determinant of history, and not always the most important.

If and when a new form of civilization emerges from developments in our present civilization, we (or, rather, our descendants) may create a civilization in which economic motives are as deemphasized as they are today emphasized. Indeed, I think it is plausible to argue that the strength of economic motives operating today may issue in a backlash. A favorite futurist motif is that of an economy of maximized abundance. While I am not predicting this, or offering an opinion on its likelihood, I will only observe that in such a society economic motives more more-or-less vanish precisely because the preceding civilization had attended so relentlessly to the provision of economic needs.

Nick Nielsen June 4, 2015 at 5:21

RE: John Hunt

“And then one of the transhumans chooses to exert control over all else by means of becoming an accelerating AI…”

There would be competition, and that means that it would be unlikely, or at least very difficult, or any one AI in accelerating development to outpace peers and therefore acquire an undisputed position of power.

Also, it should be expected that the voluntaristic divergence made possible by the technological enhancement of human abilities will be used in many and very different ways. Forms of intelligence can be complementary and only overlap in some basic functions. The more some particular capacity is developed, it is likely to come at the expense of other capacities. Thus specialized acceleration would always be vulnerable to some other specialization that the former does not fully understand and therefore against which it cannot fully protect itself.

Nick Nielsen June 4, 2015 at 5:33

RE: Alex Tolley

Addressing, for the moment, only the first of your comments, I agree with most of what you say. However, I don’t think it is a matter of FTL/no FTL starships as an either/or structure of future possibilities. As I argued in the post you noted (“How We Get There Matters”), we should expect to see a spectrum of possible interstellar technologies, some of them practicable and some of them not. There would be a very big difference between very long term generation ships, and starships of a single generation, 1G starships, and finally starships that use some loophole in general relativity (wormholes or spacetime manipulation) to achieve the practical equivalent of FTL travel. Again, I see these technological possibilities in light of the Great Voluntaristic Divergence. And if one were to suppose that an intelligence explosion occurs prior to any kind of rapid divergence of interstellar technologies, the former will serve of facilitate the latter.

Every possible permutation of technologies comes with biological consequences, as you imply. Some of these consequences might facilitate the ongoing dominance of a particular species or cohort of species, while other consequences following from other technological permutations might hamper dominance of a species or species cohort to the point of near impossibility. I would argue for the latter, but I do not dismiss the former out of hand.

RE: Harold Daughety

“My assigned contacts among the clients were actually living more intensively than ever before in their lives.”

Isn’t this what happens to Walter White in Breaking Bad after he receives a fatal diagnosis? While we might assimilate the “intense” living experiences of Walter White to a “dark enlightenment” paradigm, human diversity implies that different individuals will respond to their mortality in different ways, some of them socially approved, and some of them socially condemned. As technology extends the scope of human agency, I expect this consequence of diversity to continue, with even more spectacular instances of both socially approved and socially condemned intensity and divergence. This is the adaptive radiation of the human spirit.

RE: ole burde

“…is the idea of Transhumanism just a smart way to get around the painful and explosive debate about Human Genetic Engineering?”

No. It is more than that. Genetic engineering is one method among many possible technologies that could be employed to mitigate or eliminate human limitations. It could also be used (as could other technologies) to augment human limitations in terms of number and kind of limitations.

I am not making any attempt whatsoever to skirt or avoid a painful or explosive debate. But the debate is much larger than genetic engineering. In fact, if we look at society today we are doing out best to avoid talking about human genetic engineering, but transhumanist initiatives by any other name are present everywhere we look, so even if genetic engineering is taken off the table for social, moral, religious or even PR reasons, the debate over transhumanism goes on.

“Is it possible to imagine a future where a subspecies of humans are designed for life in space, or elsewhere, while at the same time a total ban on human genetic engineering is enforced on earth?”

“Is it possible for the human species to expand into space without using the tool of human genetic engineering?”

Both are possible. I would even argue that both are likely to occur in the long term. On Earth it is pretty easy to control scientific research on a large scale, but once there is a viable human population off planet there will be countless opportunities to conceal controversial activities, and eventually (as you implied in your earlier comment), “As time passes by , certain unexploited benefits become bigger, and the cost of realizing them grows smaller. Before or later the process we call evolution will short-circuit this potential, and when this happens it will not be according to a specific human-style ‘plan’ we can recognize.” I completely agree with this.
