My theory appears to me quite incontrovertible and conclusive, and to afford a complete explanation of the entire set of phenomena. The exposition, however, must now face a set of facts which appear quite opposed to it, and which seem absolutely to contradict my reference of sexual inversion to the existence of sexually intermediate types, and my explanation of the law governing the attraction of these types for each other. It is probably the case that my explanation is sufficient for all female sexual inverts, but it is certainly true that there are men with very little taint of femaleness about them who yet exert a very strong influence on members of their own sex, a stronger influence than that of other men who may have more femaleness--an influence which can be exerted even on very male men, and an influence which, finally, often appears to be much greater than the influence any woman can exert on these men. Albert Moll is justified in saying as follows: “There exist psycho-sexual hermaphrodites who are attracted by members of both sexes, but who in the case of each sex appear to care only for the characters peculiar to that sex; and, on the other hand, there are also psycho-sexual (?) hermaphrodites who, in the case of each sex, are attracted, not by the characteristics peculiar to that sex, but by those which are either sexually indifferent or even antagonistic to the sex in question.” Upon this distinction depends the difference between the two sets of phenomena indicated in the title of this chapter--Homo-sexuality and Pederasty. The distinction may be expressed as follows: The homo-sexualist is that type of sexual invert who prefers very female men or very male women, in accordance with the general law of sexual attraction. The pederast, on the other hand, may be attracted either by very male men or by very female women, but in the latter case only in so far as he is not pederastic. Moreover, his inclination for the male sex is stronger than for the female sex, and is more deeply seated in his nature. The origin of pederasty is a problem in itself and remains unsolved by this investigation. CHAPTER V THE SCIENCE OF CHARACTER AND THE SCIENCE OF FORM
