_Hirschfeld_ does not admit the influence of latent homosexuality in the choice of this androgenic type. A homosexual whose condition is not manifest he does not recognize. His ground for diagnosis is no longer similarity of bodily traits when compared with the opposite sex. The determining factor for _Hirschfeld_ is only the subject’s feeling. _If he is homosexually inclined (particularly if so disposed from childhood), the subject is homosexual._ _Hirschfeld’s_ own statement is as follows: “The determining factor in the diagnosis of homosexuality remains as before the contrary feeling proper; the diagnosis is strongly supported by a negative attitude towards the other sex, as well as by altero-sexual episodes, although these two features in themselves are not capable of establishing the diagnosis.” Since _Bloch_ also admits that there are many virile homosexuals with bodily structures wholly male, it follows that the organic diagnosis of homosexuality is altogether unreliable. _Hans Blüher_, a reliable expert on homosexuality, also recognizes the pure homosexual, which he calls the “male hero” type, whose character and habitus is completely male, thus differing from the second type, the “woman-like invert” (_invertierter Weibling_). The latent homosexual he considers a third type. (Vid. _Die drei Grundformen der Homosexualitaet: Eine sexuologische Studie._ Jahrbuch f. sexuelle Zwischenstuffen, vol. XIII). Let us repeat and underscore the far-fetched feature of this method of diagnosis. According to it _there is no objective means for ascertaining homosexuality. The only diagnostic guide is the homosexual’s declaration that he has always felt homosexually inclined and that he is indifferent towards the other sex._ The analyst is well qualified to recognise the utter weakness of such a diagnostic guide. We meet continually persons who claim to know themselves thoroughly; they claim that they have investigated their own state very conscientiously but after a few weeks, often only after a few days (illustrations will be fully given in this book) the subject must admit that he did not know himself, that, in fact, he had avoided knowing himself. _All persons lie about sexual matters and deceive themselves in the first place._ All play _Vogel-strauss-politik_, the ostrich. _All neurotics falsify their life history or at least retouch it._ They simply forget the facts which do not suit their system of thinking. We must also bear in mind _Havelock Ellis’_ statement that the homosexuals prefer to consider themselves as normal. Similarly the childhood history is distorted consciously or unconsciously and a life history is reconstructed (in retrospect) from which all heterosexual episodes have been eliminated.
