The author is the wife and associate of J.B. Rhine, former head of the Duke University Parapsychology Laboratory who now heads the Foundation for Research on the Nature of Man, an institute also devoted to the study of the psi process known as ESP. She is also co-editor of the Journal of Parapsychology. This book, written to call attention to the scientific investigations made in this area, is far more comprehensive and rational than the many others whose major claim to fame is heightened by unenlightened imagination. She discusses and analyzes lab experiments (particularly those at Duke University) as well as many of the spontaneous cases (unusual occurrences, usually once-in-a-lifetime, voluntarily reported by reliable individuals) recorded here. The research methods and experiments will be of particular interest to those involved in this field while the reports themselves will intrigue the layman. While the book-does not pretend to definition or conclusion, it does point up a ""consistent outline"" as proof of the psi process at work and worthy of continued study.
