"This is one of the finest examples of intellectual history I have seen in a long while. It is insightful, thoughtful, informative, and highly readable. Rather than simply connecting the dots, so to speak, the author provides a sophisticated and nuanced examination of numerous German thinkers of the late nineteenth and early twentieth centuries who were influenced to one degree or another by Darwinist naturalism and their ideas, subtly drawing both distinctions and similarities and in the process telling a rich and colorful story."--Ian Dowbiggin, University of Prince Edward Island and author of A Merciful End: The Euthanasia Movement in Modern America
"Richard Weikart's outstanding book shows in sober and convincing detail how Darwinist thinkers in Germany had developed an amoral attitude to human society by the time of the First World War, in which the supposed good of the race was applied as the sole criterion of public policy and 'racial hygiene'. Without over-simplifying the lines that connected this body of thought to Hitler, he demonstrates with chilling clarity how policies such as infanticide, assisted suicide, marriage prohibitions and much else were being proposed for those considered racially or eugenically inferior by a variety of Darwinist writers and scientists, providing Hitler and the Nazis with a scientific justification for the policies they pursued once they came to power."--Richard Evans, University of Cambridge, and author of The Coming of the Third Reich
"This is an impressive piece of intellectual and cultural history--a well-researched, clearly presented argument with good, balanced, fair judgements. Weikart has a thorough knowledge of the relevant historiography in both German and English."--Alfred Kelly, Hamilton College
"Taking a middle ground between scholars on both sides, Richard Weikart has traveled far and wide to bring together a broad range of important programs, institutions, and thinkers who shaped the social and political ramification of Darwinian thought in late nineteenth and early twentieth century Germany. Many of the voices Weikart conveys appear here in English for the first time."--Kevin Repp, Yale University
