Psychology and the Occult Over his long career, Jung maintained a compelling interest in occult phenomena as a subject of psychological concern. His first publication, his M.D. dissertation in 1902, was, a psychiatric study of a medium, and he "dabbled in spookery" (as he wrote Freud) in his undergraduate days and before. His letters and autobiography frequently comment on parapsychological phenomena. The present collection brings together Jung's writings on the occult in the Collected Works, beginning with the 1902 monograph and coming up to 1960, the year before his death. In "On the Psychology and Pathology of So-called Occult Phenomena" Jung describes several clinical cases of double consciousness, twilight states, and somnambulism, then details the case of an adolescent girl "psychic" who had visions and held seances which Jung attended in his student days. In 1905 Jung gave a public lecture in Basel "On Spiritualistic Phenomena" in which he surveyed the history and psychology of the subject in America and Europe and told of his own experience investigating eight mediums in Zurich. This work of Jung's was brought to light only recently. The Psychological Foundations of Belief in Spirits"  (1919) and "The Soul and Death" (1934) both clinically and philosophically illustrate Jung's continued interest in parapsychology. Three late forewords to books by Stewart Edward White, Fanny Moser, and Aniela Jaffe, and Jung's answers to a questionnaire on "The Future of Parapsychology" (1960) complete the selection. These paperback editions of C. G. Jung's writings are selected from the Collected Works, translated by R.F.C. Hull and originally published as Bollingen Series XX. The present paperback is composed of papers from Psychiatric Studies, Volume 1; The Structure and Dynamics of the Psyche, Volume 8; and The Symbolic Life, Volume 18.
