Jealousy need not always have a sexual motive. A woman may be jealous of her husband’s friend because he has been more successful than her husband. Her husband is her possession. He ought to be the foremost, he ought to have achieved the others’ successes, so that his fame should revert to her too. Pupils are jealous of one another even though not a trace of a sexual motive may be demonstrable. We may be jealous of another’s horses, dogs, furniture, virtues, honours, friendships, responsibilities, etc. Behind it there always is our brutal egoism, the desire for another’s possessions, or at least the fear of losing one’s own possession. Jealousy is generally regarded as a pre-eminently feminine quality. Erroneously so. It would be more nearly correct to say that the heroic side of jealousy is to be found only in men. It is not a matter merely of chance that we have no feminine counterpart to Othello, Herod and the Count in Hauptmann’s “Griselda.” Jealousy in women has received a social valuation from men; it always has a smack of the ridiculous, pathological, or unjustified. It is a subject for satire, and is more often a comedy motive than a tragic reproach. This is due to the fact that woman’s love is monopolised by men, whereas a man’s loyalty is demanded by most women but attained only by very few. A man’s infidelity is not a dramatic reproach because it is a daily occurrence and wholly in accord with the lax conception of the majority. A woman’s infidelity is an offence against the sacred mandates imposed by--men. And therefore the jealousy of a man--be the subject of the passion a fool, a fop, an old man, or some other laughable type destined for cuckoldry--is a struggle for just possession, a conflict which always has an heroic effect, whereas a woman’s jealousy is always a dispute for the sole possession of a man, a right which is disputed by a great majority (namely, the men, and even some women). But there are men and women who are not jealous even though they love intensely. And with this we hit upon a second and important root of jealousy. Only one who contemplates an act of disloyalty against the object of his jealousy, or who, as a result of doubts about his own erotic powers, thinks he cannot gratify that object can be jealous. Of course I am not now speaking of justified jealousy based on facts, but of baseless, unjustified jealousy. Whence comes the suspicion that attributes infidelity to the beloved being? What is the driving power in these cases? Only the knowledge of one’s true nature. Only they can be jealous, jealous without cause, who cannot guarantee for themselves. In other words: jealousy is the projection of one’s own shortcomings upon the beloved.
