"If biotechnology can be used to upgrade' humans physically and mentally, should it be done? And if so, to what extent? How will biotechnology affect societal cohesion, and can the development be controlled? Or is this a Pandora's box that should remain closed? These are just a few of the many questions that arise as a result of the increasing ability of technology to change biology and, eventually, transform human living conditions. This development has created a new horizon of a posthuman future that will influence contemporary life and politics in a number of ways. The book gathers researchers within the fields of biotechnology, medicine, ethics, politics, and aesthetics. Among the contributors are Francis Fukuyama, Julian Savulescu, Maxwell Mehlman, Lone Frank and Chris Hables Gray."--Provided by publisher.
