The Disconnection Thesis

In this essay I claim that Vinge’s idea of a technologically led intelligence explosion is philosophically important because it requires us to consider the prospect of a posthuman condition succeeding the human one. What is the “humanity” to which the posthuman is “post”? Does the possibility of a posthumanity presuppose that there is a ‘human essence’, or is there some other way of conceiving the human-posthuman difference? I argue that the difference should be conceived as an emergent disconnection between individuals, not in terms of the presence or lack of essential properties. I also suggest that these individuals should not be conceived in narrow biological terms but in “wide” terms permitting biological, cultural and technological relations of descent between human and posthuman. Finally, I consider the ethical implications of this metaphysics If, as I claim, the posthuman difference is not one between kinds but emerges diachronically between individuals, we cannot specify its nature a priori but only a posteriori. The only way to evaluate the posthuman condition would be to witness the emergence of posthumans. The implications of this are somewhat paradoxical. We are not currently in a position to evaluate the posthuman condition. Since posthumans could result from some iteration of our current technical activity, we have an interest in understanding what they might be like. It follows that we have an interest in making or becoming posthumans.
