This book examines the dependence of transhumanist arguments on the credibility of the narratives of meaning in which they are embedded. By taking the key ideas from transhumanist philosophy - the desirability of human self-design and immortality the elimination of all suffering and the expansion of human autonomy - Michael Hauskeller explores these narratives and the understanding of human nature that informs them. Particular attention is paid to the theory of transhumanism as a form of utopia stories of human nature the increasing integration of the radical human enhancement project into the cultural mainstream and the drive to upgrade from flesh to machine.
