An essential ingredient of any education is the willingness to face objections to one's own beliefs. One can only have knowledge rather than opinion if one can defend one's beliefs against all objections that can be put to them. The field of research on the paranormal has changed enormously in the last 20 years and this book will be an appraisal of the best available evidence to date on scientific claims of the paranormal. Covering the entire field of the paranormal, David Marks examines ESP, psychokinesis, precognition, ganzfeld, dissociative states, out-of-the-body experiences, alien abductions and near-death experiences. These are phenomena that all may appear on the surface to defy rational explanation. This book will provide a description of the psychological processes that are likely to contribute to paranormal experience and the high prevalence of paranormal beliefs. It will provide readers with the critical skills required to defend and justify scientific claims of the paranormal. This book will not take a fixed sceptical or 'disbelieving' view of the phenomena but, as far as possible, offer a neutral gaze and readers will be equipped to make up their own minds
