A number of Catholic theologians, most of them French and English, have collaborated to produce this exhaustive study of the devil. The first part of the book in theological in nature, designed to prove the existence of a personal devil and to interpret his nature and his activity. The second part of the book is more of a psychological approach to the question, dealing with demoniac possession, witchcraft and exorcism. The concluding chapters outline the place of Satan in art and literature with particular reference to Milton, Blake, Balzac, Gogol and Dostoevsky. This is primarily a book for Catholic scholars, but the increasing number of people of all faiths who realize that we must come to grips with the reality of evil will find it illuminating.
