This work contains a chapter entitled _“New Contributions to the Theory of Homosexuality.”_ Here _Sadger_ abandons entirely his former notion about the significance of the fourth year and states: “_Permanent_ inclination towards one’s own sex usually comes to surface and is certainly increased during puberty, or during the prepubescent period at the earliest, in our latitude around the tenth or eleventh year. Occasionally an earlier onset is recorded and every case of that kind is due to some special factors.” Permanent homosexuality is established through some significant incident which leads to the repression of the mother in her rôle as helper and teacher. Such incidents are death, sudden financial reverse, and consequent serious neurosis, making sanatorium treatment necessary, inconsiderate persecution of the boy on account of masturbation and similar traumata. The love feeling is turned from the mother to the father, or to older comrades, or to comrades of about the same age, who stand as substitutes for the mother and initiate the boy into the facts of love.... The path to homosexuality leads over love of self, through narcissism. “The state of being in love with one’s own person, which shows itself also in the admiration of one’s own genitalia (_sic_), is never absent as a developmental phase.” Every person has two aboriginal sexual objectives to which he clings throughout life: the mother and self. The father replaces self only for a short period because as the primary rival in his relationship to the mother the child early assumes an antagonistic attitude towards him. The _urning_ hates woman for an obvious reason: “when the best of women, my own mother, amounts to no more than that, what can there be to any other woman?” Here follows a convincing proof that the _urning_ identifies himself with his mother. The _urning_ always plans to instruct his beloved, for the mother does it. (Does not the father, rather, do it?) The patient has instructed a waiter in geology and history of art, subjects which did not interest the latter. But the mother had done the same.... Most _urnings_ are said to be “only” children. (This statement like many another of _Sadger’s_, is positively false. Among 500 homosexuals _Hirschfeld_ found only 67 “only” children and among them only 54 were sons. My own statistical figures are even smaller. But the percentage among my neurotics is practically the same.) _Sadger_ summarizes his findings in five fundamental statements: “1. The _urning_ is a victim of withdrawal from the mother (the first caretaker or nurse, respectively) in whom he is himself seriously disappointed. He represses the mother by identifying himself completely with her. 2. The path to homosexuality leads through narcissism, that is, love of self, as one was, or as one may ideally be. 3. The sexual ideal of the invert includes not only traits of former female and male sexual objectives but also features of one’s own beloved self.
