In Sorgner's 2009 paper "Nietzsche, the Overhuman, and Transhumanism", he argues, contra Bostrom, that the transhumanist movement's postman is fundamentally similar to Nietzsche's overman. In this paper, Sorgner's thesis is challenged. It is argued that transhumanism, as presented both popularly and academically, is fundamentally incompatible with Nietzsche's overman, as presented in Thus Spoke Zarathustra. This argument focuses on three significant characteristics's of Zarathustra's description of the overman: the role of earthly existence, immortality, and the rejection of collective values.
