The completion of the human genome project in 2000 dramatically emphasized the imminent success of the genetic revolution. The ethical and social consequences of this scientific development are immense. From human reproduction to life-extending therapies, from the impact on gender and race to public health and public safety, there is scarcely a part of our lives left unaffected by the impact of the new genetics. A Companion to Genethics is the first substantial study of the multifaceted dimensions of the genetic revolution and its philosophical, ethical, social, and political significance. It brings together the best and most influential contemporary writing about genethics. Newly commissioned essays from prominent figures in the current debate provide a wide-ranging and fascinating scholarly analysis of all the issues that arise from this explosive science.
