The following pages represent in the main a discussion of certain celebrated mysteries, as viewed in the light of the discoveries set forth in the writer's earlier work "The Riddle of Personality." That dealt, it may briefly be recalled, with the achievements of those scientists whose special endeavor it is to illumine the nature of human personality. On the one hand, it reviewed the work of the psychopathologists, or investigators of abnormal mental life; and, on the other hand, the labors of the psychical researchers, those enthusiastic and patient explorers of the seemingly supernormal in human experience. Emphasis was laid on the fact that the two lines of inquiry are more closely interrelated than is commonly supposed, and that the discoveries made in each aid in the solution of problems apparently belonging exclusively in the other.
