The Psychogenesis of Mental Disease presents some of Jung's most important writings on psychiatry, including "On the Psychology of Dementia Praecox," his landmark early study of what is today called schizophrenia. Also featured here are nine other key papers in psychiatry, the earliest being "The Content of the Psychoses," written in 1908, when Jung was a leading member of the early psychoanalytic movement. The latest are two papers written in 1956 and 1958, which embody Jung's conclusions after many years of experience in the psychotherapy of schizophrenia. These writings reflect the original techniques with which Jung is especially associated.
