Book excerpt: A fifteen-year-old girl who claimed regular communications with the spirits of her dead friends and relatives was the subject of the very first published work by the now legendary psychoanalyst C.G. Jung. Collected here, alongside many of his later writings on such subjects as life after death, telepathy and ghosts, it was to mark just the start of a professional and personal interest—even obsession—that was to last throughout Jung’s lifetime. Written by one of the greatest and most controversial thinkers of the twentieth century, Psychology and the Occult represents a fascinating trawl through both the dark, unknown world of the occult and the equally murky depths of the human psyche. Carl Gustav Jung (1875–1961). Founded the analytical school of psychology and developed a radical new theory of the unconscious that has made him one of the most familiar names in twentieth-century thought.
