These perverts do at least seek to achieve very much the same ends with the objects of their desires as normal people do with theirs. But after them comes a long series of abnormal types, in whom the sexual activities become increasingly further removed from anything which appears attractive to a reasonable being. In their manifold variety and their strangeness these types may be compared to the grotesque monstrosities painted by P. Breughel to represent the temptations of St. Anthony, or to the long procession of effete gods and worshippers which G. Flaubert shows us passing before his pious penitent, and to nothing else. The chaotic assembly calls out for classification if it is not to bewilder us completely. We divide them into those in whom the _sexual object_ has been altered, as with the homosexuals, and those in whom, first and foremost, the _sexual aim_ has been altered. In the first group belong those who have dispensed with the mutual union of the genital organs and who have substituted for the genitals, in one of the partners in the act, another organ or part of the body (mouth or anus, in place of the vagina) making light of both the anatomical difficulties and the suppression of disgust involved. There follow others who, it is true, still retain the genital organs as object; not, however, by virtue of their sexual function, but on account of other functions in which they take part anatomically or by reason of their proximity. These people demonstrate that the excretory functions, which in the course of the child’s upbringing are relegated to a limbo as indecent, remain capable of attracting the entire sexual interest. There are others who have given up altogether the genital organs as object; and, instead, have exalted some other part of the body to serve as the object of desire, a woman’s breast, foot, or plait of hair. There are others yet to whom even a part of the body is meaningless, while a particle of clothing, a shoe or a piece of underclothing, will gratify all their desires; these are the fetichists. Farther on in the scale come those who indeed demand the object as a whole: but whose requirements in regard to it take specific forms, of an extraordinary or horrible nature—even to the point of seeking it as a defenceless corpse and, urged on by their criminal obsessions, of making it one in order so to enjoy it. But enough of these horrors!
