First published in 1951, Man into Wolf attempts to suggest the possibility of historical, or rather prehistorical, evolutionist derivation of all crimes of violence, from the individual attack on life known as murder or manslaughter to the collective organized killing which we call war. The author has tried to show that the evidence from prehistory can be made intelligible on the theory of Jung's archetypes surviving in the collective conscience and revealing themselves all over the world in legends, myths and rites. He discusses, in the notes on the lecture, every possible aspect of the subject ranging from the perverseness of the Marquis de Sade to the Grecian Bacchantes, and from the Green Men and the agricultural ceremonies to a case study of John George Haigh. This book will be of interest to students of anthropology, gender studies, and psychology.
