Krafft-Ebing gives the details of five cases of "acquired" sexual inversion. Three of these were the children of afflicted parents. One had no morbid strain in his ancestry, except pulmonary consumption. The fifth sprang from a strong father and a healthy mother. Masturbation entered into the history of all.
It must be observed, in criticising Krafft-Ebing's theory, that it is so constructed as to render controversy almost impossible. If we point out that a large percentage of males who practise onanism in their adolescence do not acquire sexual inversion, he will answer that these were not tainted with hereditary disease. The autobiographies of onanists and passionate woman-lovers (J. J. Rousseau, for example, who evinced a perfect horror of homosexual indulgence, and J. J. Bouchard, whose disgusting excentricities were directed toward females even in the period of his total impotence) will be dismissed with the remark that the ancestors of these writers must have shown a clean record.
It is difficult to square Krafft-Ebing's theory with the phenomena presented by schools, both public and private, in all parts of Europe. In these institutions not only is masturbation practised to a formidable extent, but it is also everywhere connected with some form of sexual inversion, either passionately Platonic or grossly sensual. Nevertheless, we know that few of the boys addicted to these practices remain abnormal after they have begun to frequent women. The same may be said about
