In the media and in academia, there are few topics more fiercely debated than that of posthumanism. This volume inquires into the knowledge formation of the biological, philosophical and medial self-displacement of the human in anti-, post-, and transhumanism. The articles investigate how practices inscribe themselves into discourses, and what effects the subversion of the »human« has: what sort of boundaries are created? What sort of possibilities arise? Contributors from Philosophy, Neuroscience, and Media Studies, including Christina Brandt, Nick Bostrom, Ron-Cole Turner, Steve Fuller und Oliver Müller, throw light on the limits of the »human«.
