We imagine posthumans as humans made superhumanly intelligent or resilient by future advances in nanotechnology, biotechnology, information technology and cognitive science. Many argue that these enhanced people might live better lives; others fear that tinkering with our nature will undermine our sense of our own humanity. Whoever is right, it is assumed that our technological successor will be an upgraded or degraded version of us: Human 2.0. Posthuman Life argues that the enhancement debate projects a human face onto an empty (...) screen. We do not know what will happen and, not being posthuman, cannot anticipate how posthumans will assess the world. If a posthuman future will not necessarily be informed by our kind of subjectivity or morality the limits of our current knowledge must inform any ethical or political assessment of that future. Posthuman Life develops a critical metaphysics of posthuman succession and argues that only a truly speculative posthumanism can support an ethics that meets the challenge of the transformative potential of technology.

Most contemporary readings of Derrida’s work situate it within a transcendental tradition of philosophical enquiry explicitly critical of naturalistic accounts of knowledge and mind. I argue that Derrida provides the naturalist with some of the philosophical resources needed to rebut transcendental critiques of naturalism, in particular the phenomenological critiques which derive from Husserl’s philosophy. I do this by showing: a) that Derrida’s account of temporality as differance undermines phenomenological accounts of the meaning of naturalistic theories and assumptions; and b) that (...) it is itself both usable and interpretable within the naturalistic framework of current cognitive science.

I distinguish the ethics of transhumanism from a related metaphysical position which I refer to as “speculative posthumanism.” Speculative posthumanism holds that posthumans might be radically non-human and thus unintelligible in human terms. I claim that this transcendence can be viewed as analogous to that of the thing-in-itself in Kantian and post-Kantian European philosophy. This schema implies an impasse for transhumanism because, while the radically non-human or posthuman would elude evaluation according to transhumanist principles such as personal autonomy or liberal (...) freedom, it is morally unacceptable for transhumanists to discount the possible outcomes of their favoured policies. I then consider whether the insights of critical posthumanists, who employ a cyborg perspective on human-technology couplings, can dissolve this impasse by “deconstructing” the opposition between the human and its prospective posthuman successors. By exhibiting its logical basis in the postructuralist philosophies of Derrida and Deleuze, I show that the cyborg perspective is consistent with both cyborg humanism and a modified speculative posthumanism. This modified account treats the alterity of the posthuman as a historically emergent feature of human and posthuman multiplicities that must be understood through their technical or imaginative synthesis, not in relation to a transcendental conception of the human.
