This case is in every way interesting and of great significance for our problem. It proves to us the great determinative role of a childish reminiscence and the persistence of a scene which is continually repeated in memory. The whole of that young man’s libido is centered around that particular scene. He stages it also in the brothel when he hires an old man to have intercourse in his presence. That old man assumes then the role of the father, the prostitute is the mother, while he is once more the onlooking child. The act of looking on so excites his passion that with that aid he proves potent in his intercourse with the prostitute. But that continues only so long as the exciting influence of the scene persists. After that he reverts to his former impotence and he again ... seeks his father. It is perfectly plain, and only the blind could fail to see that T. seeks his father. His wish was obviously that his father should also start something sexual with him. It is possible that he had identified himself with his mother. But we have no direct proof of that. This is particularly significant because _Sadger_ and the others who belong to _Freud’s_ narrower circle place great emphasis upon the role of the mother in the genesis of genuine homosexuality while neglecting ruefully the role of the father. This case shows us a “Japhet, who seeks his father.” The promenades with the respectable old gentleman are repetitions of the walks with his father. This patient does not recall any heterosexual experiences during his youth, probably because the memory of them has been repressed from consciousness. In the other case which I shall now quote from _Krafft-Ebing_ the heterosexual period is clearly recalled. I refer the reader to that author’s _Observation 144_. Here I quote the first part of the history of that case:
