David Roden on Posthuman Life

by Steven Craig Hickman

 There evolved at length a very different kind of complex organism, in which material contact of parts was not necessary either to coordination of behaviour or unity of consciousness. . . .

—OLAF STAPLEDON, First and Last Men

When Stapledon wrote that book he was thinking of Martians, but in our time one might think he was studying the strangeness of what our posthuman progeny may evolve into.  In Last and First Men Stapledon presents a version of the future history of our species, reviewed by one of our descendants as stellar catastrophe is bringing our solar system to an end. Humanity rises and falls through a succession of mental and physical transformations, regenerating after natural and artificial disasters and emerging in the end into a polymorphous group intelligence, a telepathically linked community of ten million minds spanning the orbits of the outer planets and breaking the bounds of individual consciousness, yet still incapable of more than “a fledgling’s knowledge” of the whole.1
​
Modern humans (Homo sapiens or Homo sapiens sapiens) are the only extant members of the hominin clade, a branch of great apes characterized by erect posture and bipedal locomotion; manual dexterity and increased tool use; and a general trend toward larger, more complex brains and societies. We evolved according to Darwinian theory from early hominids, such as the australopithecines whose brains and anatomy in many ways more similar to non-human apes, are less often thought of or referred to as “human” than hominids of the genus Homo some of whom used fire, occupied much of Eurasia, and gave rise to anatomically modern Homo sapiens in Africa about 200,000 years ago where they began to exhibit evidence of behavioral modernity around 50,000 years ago and migrated out in successive waves to occupy all but the smallest, driest, and coldest lands. (see Human)

You begin to see a pattern that evolution moves through various changes and transformations. Yet, there is no end point, no progression, not teleological goal to it all. Instead evolutionary theory – and, more explicitly its modern synthesis, connected natural selection, mutation theory, and Mendelian inheritance into a unified theory that applied generally to any branch of biology. One thing that sticks out in this is that evolution deals with organic evolution. The modern synthesis doesn’t include other types of evolvement that might portend what the posthuman descendants of humans might become. If we follow the logic of evolutionary theory as it exists we could at best extrapolate only the continued organic evolution of humans or their eventual extinction. We know that extinction is a possibility since 99% of the species that have ever existed on earth are now extinct. Something will eventually replace us. But what that ‘something’ might be is open to question, an open ended speculative possibility rather than something a scientist could actually pin down and point to with confidence.

This is the basic premise of Dr. David Roden’s new work, Posthuman Life: Philosophy at the Edge of the Human. We are living in a technological era in which a convergence of NBIC technologies (an acronym for Nanotechnology, Biotechnology, Information technology and Cognitive science), as well as certain well supported positions in cognitive science, biological theory and general metaphysics imply that a posthuman succession is possible in principle, even if the technological means for achieving it remain speculative (Roden, KL 157). Roden will term his version of this as “speculative posthumanism”:

Throughout this work I refer to the philosophical claim that such successors are possible as “speculative posthumanism ” (SP ) and distinguish it from positions which are commonly conflated with SP, like transhumanism. SP claims that there could be posthumans. It does not imply that posthumans would be better than humans or even that their lives would be compared from a single moral perspective.2

Roden will develop notions of “Critical Posthumanism” — which seeks to “deconstruct” the philosophical centrality of the human subject in epistemology, ethics and politics; and, Transhumanism — which proposes the technical enhancement of humans and their capacities.Yet, as Roden admits before we begin to speak of the posthuman we need to have some inkling of exactly what we mean by ‘human’: any philosophical theory of posthumanism owes us an account of what it means to be human such that it is conceivable that there could be nonhuman successors to humans (Roden, KL 174).

One thought that Roden brings out is the notion of subjectivity:

Some philosophers claim that there are features of human moral life and human subjectivity that are not just local to certain gregarious primates but are necessary conditions of agency and subjectivity everywhere. This “transcendental approach” to philosophy does not imply that posthumans are impossible but that – contrary to expectations – they might not be all that different from us. Thus a theory of posthumanity should consider both empirical and transcendental constraints on posthuman possibility. (Roden, KL 180)

Yet, such premises of an anti-intentional or non-intentional materialism as stem from Schopenhauer, Nietzsche, Bataille, and Nick Land would opt that we need no theory of subjectivity, that this is a prejudice of the Idealist tradition and dialectics that are in themselves of little worth. Obviously philosophers such as Alain Badiou, Slavoj Zizek, Quentin Meillassoux, and Adrian Johnson stand for this whole Idealist tradition in materialism in one form or another. Against the Idealist traditions is a materialism grounded in chaos and composition, in desire: Nick Land’s sense of libidinal materialism begins and ends in ‘desire’ which opposes the notion of lack: instead his is a theory of unconditional (non-teleological) desire (Land, 37).3 Unlike many materialisms that start with the concept of Being, or an ontology, Libidinal Materialism begins by acknowledging thermodynamics, chaos, and the pre-ontological dimension of energy: “libidinal materialism accepts only chaos and composition” (43). Being is an effect of composition: “being as an effect of the composition of chaos”:

With the libidinal reformulation of being as composition ‘one acquires degrees of being, one loses that which has being’. The effect of ‘being’ is derivative from process, ‘because we have to be stable in our beliefs… one has a general energetics of compositions… of types, varieties, species, regularities. The power to conserve, transmit, circulate, and enhance compositions, the power that is assimilated in the marking, reserving, and appropriation of compositions, and the power released in the disinhibition, dissipation, and … unleashing of compositions (Land, 44) … [even Freud is a libidinal materialist] in that he does not conceive desire as lack, representation, or intention, but as dissipative energetic flow, inhibited by the damming and channeling apparatus of the secondary process (Land, 45).

R. Scott Bakker author of the fantasy series The Second Apocalypse is also the theoretician of what he terms Blind Brain Theory (BBT). Very briefly, the theory rests on the observation that out of the vast amount of information processed by the brain every nanosecond, only a meagre trickle makes it through to consciousness; and crucially that includes information about the processing itself. We have virtually no idea of the massive and complex processes churning away in all the unconscious functions that really make things work and the result is that consciousness is not at all what it seems to be. Even what we term subjectivity is but a temporary process and effect of these brain processes and has no stable identity to speak of, but is rather a temporary focal point of consciousness. (see The Last Magic Show)

So to come back to Roden’s statement that some “philosophers claim that there are features of human moral life and human subjectivity that are not just local to certain gregarious primates but are necessary conditions of agency and subjectivity everywhere (Roden, KL 180)”. We can with BBT and Libidinal Materialism, or what might be better termed an anti-intentional philosophy based on non-theophilosophical concepts throw out the need to base our sense of what comes after the human on either ‘agency’ or ‘subjectivity’ as conditions, for both are in fact effects of the brain not substance based entities. So Roden need not worry about such conditions and constraints. And, as he tells us weakly constrained SP suggests that our current technical practice could precipitate a nonhuman world that we cannot yet understand, in which “our” values may have no place (Roden KL 187). Which is this sense that our human epistemologies, ontologies and normative or ethical practices and values cannot tell us anything about what the posthuman might entail: it is all speculative and without qualification.

But if this is true he will ask:

Does this mean that talk of “posthumans” is self-vitiating nonsense ? Does speaking of “weird” worlds or values commit one to a conceptual relativism that is incompatible with the commitment to realism? (Roden, KL 191)

If posthuman talk is not self-vitiating nonsense, the ethical problems it raises are very challenging indeed. If our current technological trajectories might result in the world turning posthuman, how should we view this prospect and respond to it? Should we apply a conservative , precautionary approach to technology that favours “human” values over any possible posthuman ones? Can conservatism be justified under weakly constrained SP and, if not, then what kind of ethical or political alternatives are justifiable? (Roden, 193)

David comes out of the Idealist traditions which I must admit I oppose with the alternate materialist traditions. As he tells us:

As I mentioned, an appreciation of the scope of SP requires that we consider empirically informed speculations about posthumans and also engage with the tradition of transcendental thought that derives from the work of Kant, Hegel, Husserl and Heidegger. (Rode, KL 200)

These are the questions his book raises and tries to offer tentative answers too:

I’ve only begun reading his new work so will need to hold off and come back to it in a future post. Knowing that his philosophical proclivities bend toward the German Idealist traditions I’m sure I’ll have plenty to argue with, yet it is always interesting to see how the current philosophies are viewing such things as posthumanism. So I looked forward to digging in. So far the book offers so far a clear and energetic, and informative look at the issues involved. After I finish reading it completely I’ll give a more informed summation. Definitely a work to make you think about what may be coming our way at some point in the future if the technologists, scientists, DARPA, and capitalist machine are any sign. Stay tuned…
