Analysis has taught us how misleading the first accounts are as obtained from the subjects, how much they recollect their past in a spirit of partizanship. Every person carries out a one-sided choice of remembrances recalling merely what suits a particular occasion. This came to me as a great surprise when I first undertook the analysis of a homosexual especially as at the time my experience was limited and my knowledge of the technique and my understanding of resistance very imperfect. At the time I still believed that the patient wills to get well; I am convinced today that the will to be ill is the strongest force which we must fight against. That first homosexual gave me the usual history,—the development from early childhood of feelings exclusively homosexual. My surprise was great when the subject recalled a large number of heterosexual experiences in the course of the following three weeks, all dating from his childhood. I learned then in one lesson that homosexuality is _developmental_ and not something _inborn_; _an acquired, not an inherited character_. I was much impressed with _Hirschfeld’s_ theory of the intermediary stage (_Zwischenstufentheorie_) but placed no credence in this theory and awaited further proofs. At the First Psychoanalytic Congress, _Sadger_ reported similar experiences based on psychoanalysis. To be sure, _Sadger_ conceived the psychogenesis of homosexuality in rather narrow terms and for a time, I must confess, I too looked upon the repression of the mother Imago, which every woman is alleged to reproduce, as the sole cause of homosexuality.[27] But my diligent researches extending over a period of years have since convinced me that this problem is very complicated and that there are clearly a number of genetic factors, and that several of them must and do cooperate in every instance to bring about the thwarting of the heterosexual and the enlargement of the homosexual craving.
