A Tentative Psychological Theory of Acquired Hysteria, Many Phobias and Obsessions, and Certain Hallucinatory Psychoses.
AFTER an exhaustive study of many nervous patients afflicted with phobias and obsessions a tentative explanation of these symptoms urged itself upon me. This helped me afterwards happily to divine the origin of such morbid ideas in new and other cases, and I therefore believe it worthy of reporting and further examination. Simultaneously with this "psychological theory of phobias and obsessions," the examination of these patients resulted in a contribution to the theory of hysteria, or rather in an alteration of the same, which seems to imply an important and common character to hysteria as well as the mentioned neuroses. Furthermore I had the opportunity to look into the psychological mechanism of a form of indubitable psychic disease and found that my attempted observation shows an intelligible connection between these psychoses and the two neuroses mentioned. At the conclusion of this theme I will describe the supporting hypothesis which I have used in all three cases.
