From Darwin to Hitler ― Evolutionary Ethics, Eugenics, and Racism in Germany

From Darwin to Hitler elucidates the revolutionary impact Darwinism had on ethics and morality. Weikart demonstrates that many leading Darwinian biologists and social thinkers in Germany believed that Darwinism overturned traditional Judeo-Christian and Enlightenment ethics, especially the view that human life is sacred. Many of these thinkers supported moral relativism, yet simultaneously exalted evolutionary "fitness" (especially intelligence and health) as the highest arbiter of morality. Darwinism played a key role in the rise not only of eugenics, but also euthanasia, infanticide, abortion, and racial extermination. This thinking had its biggest impact on Germany, since Hitler built his view of ethics on Darwinian principles, not on nihilism as popularly believed.

Richard Weikart is an associate professor of modern European history at California State University, Stanislaus. He has published two previous books, including Socialist Darwinism: Evolution in German Socialist Thought from Marx to Bernstein (1999), as well as articles in German Studies Review, Journal of the History of Ideas, Isis, European Legacy, and History of European Ideas.
