[AN] The pride of the female, says Otto Weininger (Sex and Character, p. 201), is something quite peculiar to herself, something foreign even to the most handsome man, an obsession of her own body, a pleasure which displays itself even in the least handsome girl, by admiring herself in the mirror, by stroking herself and playing with her own hair, but which comes to its full measure only in the effect that her body has on man. [AO] Grudge, ill will, fear, hatred, or envy are often miscalled jealousy, but are emotions entirely different from the emotion of sexual jealousy. Jealousy is especially confused with the emotion of envy. Professional jealousy, artistic jealousy, etc., for instance, are nothing but envy. Jealousy has a real or pretended claim, envy has none. Envy needs only two persons, jealousy three. When a man, for instance, loves a woman in silence, without her knowledge or encouragement, i. e., without even a pretended claim upon her, and another man enters upon the stage, the emotion of the first man is not that of jealousy but of fear, lest the second man may succeed where he has not yet. When a man has a successful love affair, and another man appears as a disturber, the emotion of the second is that of envy. If the woman transfers her affections on the disturber, the emotion of the lover is that of jealousy, because he had a claim upon her. [AP] This accounts for the observation not seldom made in the cases of widows that the children of the second husband bear a certain resemblance with the first dead one. [AQ] The experiments of Waldstein and Elder show that every congressio, ending in the male ejaculation within the vagina, causes a certain saturation of the female blood with a substance, owing its origin within the male body, and exercises a certain change in the female blood. These authors have shown by experiments on rabbits (Archiv für Kriminalanthropologie und Kriminalistik, Vol. 56, p. 364) that the male sperma within the female organism represents a foreign body in the sense of Abderhalden. When the sperma has entered the blood of the female organism it produces there a specific ferment. The blood of a rabbit, twenty-four hours after copulation, possesses the quality of dialyzation upon testicular tissue. This reaction is positive after every copulation, no matter whether fertilization has taken place or not. Thus a part of the male circulates within the blood of the female, even after copulation without fertilization. PART VI. PATHOLOGY OF SEXUALITY CHAPTER XV PARADOXIA The pathology of love treats only of sensual love or of sensuality. The anomalies of sentimental love lie more properly within the province of the metaphysician or sociologist. Hence only the pathologic aspect of sensuality will be considered in the following part.
