Review of Babies by Design: The Ethics of Genetic Choice by Ronald M. Green and Enhancing Evolution: The Ethical Case for Making People Better by John Harris
by Richard Hayes, The American Interest (January - February 2008)
"Our common human nature evolved over millions of years but has been stable over the few thousand years during which modern human values, behaviors and institutions have developed. When we look into the eyes of another person, we know something about that person-indeed, an enormous amount, far more than we realize-no matter how dissimilar we may otherwise be. Manipulating the foundations of human nature would change all this. If human minds start modifying the basic structures of the human mind-that is, if the agent of change becomes the object of change-there will no longer be a "there" there. We will have destabilized both the biological and social foundations of the human world."
