Krafft-Ebing, already referred to, has described the peculiar sexual feeling of the invert as a functional sign of degeneration, and as a partial manifestation of a neuro-(psycho-)pathic state, in most cases (he believed) heriditary. He has catalogued the following characteristics as signs of this disorder: 1. The sexual life of individuals thus organized manifests itself, as a rule, abnormally early, and thereafter with abnormal power. Not infrequently still other perverse manifestations are presented besides the abnormal method of sexual satisfaction, which in itself is conditioned by the peculiar sexual feeling. 2. The psychical love manifest in these men is, for the most part, exaggerated and exalted in the same way as their sexual instinct is manifested in consciousness, with a strange and even compelling force. 3. By the side of the functional signs of degeneration attending antipathic sexual feeling are found other functional, and in many cases anatomical, evidences of degeneration. 4. Neurosis (hysteria, neurasthenia, epileptoid states, etc.) co-exist. Almost invariably the existence of temporary or lasting neurasthenia may be proved. As a rule, this is constitutional, having its root in congenital conditions. It is awakened and maintained by masturbation or enforced abstinence. (We have already considered the fallacious reasoning of ascribing homosexuality to masturbation. W. J. F.) 5. In the majority of cases, psychical anomalies (brilliant endowment in art, especially music, poetry, etc., by the side of bad intellectual powers or original eccentricity) are present, which may extend to pronounced conditions of mental degeneration (imbecility, moral insanity). In many urnings, either temporary or permanent insanity of a degenerative character (pathological emotional states, periodical insanity, paranoia, etc.) makes its appearance. 6. In almost all cases where an examination of the physical and mental peculiarities of the ancestors and blood relations has been possible, neurosis, psychosis, degenerative signs, etc., have been found in the families. It is Krafft-Ebing’s view that the study of antipathic sexual feeling points directly to anomalies of the cerebral organization of the afflicted individuals. “The very fact that in these cases, with few exceptions, the sexual glands are found quite normal, anatomically and functionally, seems to favor this assumption.”
