"In this follow-up to From Darwin to Hitler, Richard Weikart helps unlock the mystery of Hitler's evil by demonstrating that Hitler's immorality flowed from a seemingly coherent ethic. Hitler was inspired by evolutionary theory to pursue the utopian project of biologically improving the human race, and this ethic underlay or influenced almost every major feature of Nazi policy: eugenics, euthanasia, racism, population expansion, offensive warfare, and racial extermination. This study lends a new understanding to a divisive twentieth-century figure and the field of evolutionary studies."--BOOK JACKET.
