Penetrating and lucid…This is the definitive critique of what [Agar] calls ‘radical enhancement.’—Monash Bioethic Review—
An evenhanded treatment of an area ripe for serious philosophical scrutiny. Agar’s analysis is philosophically astute, empirically informed, and historically shrewd. It is a welcome corrective to the occasional extravagancies of the human sciences.
—Quarterly Review of Biology
Agar’s book is a valuable survey of the most important interlocutors in the conversation about posthumanism…should be taken seriously…one may well be persuaded by Agar’s arguments.
