This book, first published in 1962, is based on a series of lectures first given at Cambridge University in 1959 and 1960, dealing with 'psychical research' - i. e. the scientific investigation of ostensibly paranormal phenomena. Split into three sections, Professor Broad's study examines numerous issues relating to psychical theory, including guessing, hallucinatory quasi-perception and trance-mediumship. | Lectures On Psychical Research (routledge Revivals) by C.
