For the same reasons the quality of the sexual sensations and sentiments may vary in a hysterical subject according to the influences it is subjected to, and pass from the normal to the perverted state, or inversely. I have observed a case where a highly cultured hysterical subject, in her early youth, fell in love with another young girl. At this period her sentiments were purely homosexual; her love for the young girl was clearly inverted and accompanied by intense sexual desire, while she was absolutely indifferent to men. Later on, a man fell in love with her, and she yielded to him rather from pity and feminine passiveness than from love. Still later she fell passionately in love with another man, quite as much as she had been with the young girl of her early youth. Her latest love was both exalted and libidinous. Her sexual appetite had thus taken the normal direction under the influence of a hetero-sexual affection. In hysterical men analogous changes occur less easily, on account of the nature of masculine sexuality which distinguishes more clearly between the mind and the appetite; but these changes are observed sometimes. In woman, the hysterical imagination and dissociation facilitate a polyandrous irradiation of the sexual appetite, which is otherwise rare in the female sex. In this respect the sexuality of hysterical women resembles that of men and differs from that of normal women. Hysterical men, on the other hand, become more feminine, not by their appetite being less polygamous, but by the more dissociated form of their thoughts and sentiments. (9). A variety of the pathological love of abnormal individuals is _imaginary love_, not founded on delirious ideas. Certain psychopaths of both sexes are convinced that they love some one, but they suddenly perceive during their betrothal, or even only after marriage, that they are mistaken and that they have never loved the person in question. Such illusions are the cause of numerous broken engagements, divorce and conjugal bitterness. (10). _Amorous tyranny_ constitutes another variety in the pathology of love. Lovers of this kind constantly tyrannize and torment the object of their passion, by their desires, their observations, their sensitive temper, their contradictions, their exigencies and their jealousy. This atrocious manner of loving is common in both sexes; perhaps more so in women than men. (11). The _love of psychopaths_ is a subject which has no end. If human society was better acquainted with psychopathology a great deal of conjugal misunderstanding and misery would be avoided.
