A unique combination of horse sense and drollery has made Martin Gardner the undisputed dean of the critics of pseudoscience. This bountiful collection of essays and articles will be wholeheartedly greeted by Gardner's fans, as well as by new readers. This collection of articles - many of which first appeared in the "Skeptical Inquirer", "The New York Review of Books", and "Free Inquiry" - explores pseudoscience and strange religious beliefs with the author's trademark wit and verve. Destined to be a classic of sceptical literature, this book covers a wide range of topics - including UFOs, rainmaking, ghosts, the Big Bang, ESP, Oral Roberts, as well as the early history of spiritualism and today's bizarre 'trance channelling' cults.
