This book looks at how Darwinism has adversely affected morality in Western culture, not only sexual morals, but also the mistreatment of minority races, the killing of the sick and diseased and the rise of the abortion movement. Key figures of the twentieth century are considered: Havelock Ellis, Margaret Sanger, Friedrich Nietzsche, Sigmund Freud, Benjamin Spock, Karl Pearson, Anders Behring Breivik and others. The ideological impact of Darwinism on such issues as eugenics, abortion, racism, war and social policy since Charles Darwin's On the Origin of Species was first published in 1859 is profound. Overturning the predominately Judeo-Christian worldview of previous centuries, Darwinism has infiltrated every area of science, philosphy, art, literature, business, anthropology, social policy, governance and medicine. We need to understand the foundational problem in order to propose ways that societal reforms can be addressed in our day--this book will help us do just that.
