Why this book?
Understanding human nature – nice and nasty – demands that we dig into the past, and this brings us at once to evolution. What are we and why are we? The powerful conceptual tool that we use for explanations is Charles Darwin’s theory of evolution through natural selection. The Descent of Man is about human evolution. At times it reads very much like something out of the nineteenth century – Charles Darwin’s discussion of women makes your hair stand on end (and, if it doesn’t, it should). But the central doctrine of evolution through natural selection brought on by the struggle for existence is right there and once you grasp that, you have grasped the key to unlocking the main issues.
