Enough: Genetic Engineering and the End of Human Nature (Revised)Paperback - Revised, 1 February 2005

Scientists may soon reprogramme a human egg or sperm cell, make a change in the genetic instructions carried by that cell, a change that can be passed on down into eternity. The author asks should this happen? He argues that genetic engineering and the technologies that lie beyond it can launch us free of our past, of our humanity, of meaning.
