“I agree with _Freud_ that the homosexual or homopsychic component of man and woman finds one of its outlets, as sublimation, in the form of companionship and social drinking. But thus far I remain unconvinced that homosexuality or its psychic substitute plays also a similar rôle in the pathogenesis of the delusion of jealousy. Therefore I still adhere to the view expressed by my colleague, _Hans Oppenheim_, in his contribution, “_Zur Frage der Genese des Eifersuchtswahns_” (published in: _Zentralblatt f. Psychoanalyse_, 1911). As formerly I still regard the sadistic-masochistic instinctive cravings as the strongest root of the delusion of jealousy. I found particularly instructive a certain case in which sadism broke forth in a jealous drinker more quickly than I had ever seen that happen before. This man’s sadism manifested itself concurrently in an incredible cruelty to dogs which could be only explained by his sadism. The oft-recorded fact that the jealous drinker is not satisfied and does not release his victim even after the latter, in an attempt to quiet him, submits to some disgusting act, the continual repetition by him of tortures and cruelties, may be explained only as due to a deeply rooted sadistic impulse everlastingly craving gratification. The delusion of jealousy is rooted in sadism, the overstressed images accompanying the morbid feeling of jealousy are generated by the sadistic tendency. Sadism is the fertile soil giving rise to the delusions of persecution of the jealous alcoholics, and intimately linked with sadism stands masochism, upon which the feeling of jealousy feeds and grows.”
