Lake monsters, Yetis, UFOs, crop circles, guardian angels and visions of the Virgin Mary can all be described as apparitions, and this book weaves together an account of them. It argues that only in the last three centuries or so, and only in Western culture, they're as lively as ever. But, the author suggests, they can be made intelligible again by appealing to a different world-view. Three of the chief models for understanding mind and world are Jung's Collective World, which is used to illuminate the links between the apparently disparate experiences being dealt with.
