Originally published in 1957. This book is concerned with the conflict between "Darwinism" as the Victorians called it, and Christianity, a conflict here re-stated in modern terms because it so vitally affects our understanding of human nature and human values today. The opening chapter describes the historical background. There is a short account of evolution and the argument over Genesis. The importance of natural selection is stressed, and rival theories as to the means of animal evolution are criticised. Discussions follow on whether the course of evolution has been random or determined, on the argument from design, death in nature, the biologist¿s methods and the difficulties in evolutionary ethics.
