Colin Wilson came to realize, through his own cathartic experiences, that each of us are in fact multi-personalities, that we consist of a ladder or hierarchy of selves, and that the upper members may be called upon at will. "Man's being is like a vast mansion, yet he seems to live in a single room in the basement." Mysteries is an attempt to explain all paranormal phenomena, from dowsing to demonic possession, from precognition to Uri Geller's spoon bending, in terms of this theory of man's multiple personality. There are detailed studies of hauntings, possession and 'demonic hypnosis', and also of magic, the Kabbala and astrology. The most personal of all Colin Wilson's books, Mysteries sets out, with daring originality, to place the world of the 'unseen' in a scientific framework.
