“Furthermore we find in the insane the well-known delusion of persecution and its motive is often derived from homosexuality inasmuch as the patients complain that they are pursued with homosexual intent, of which they themselves disclaim any guilt. Or, in their morbid state of mind, they believe themselves victims of persecution because it is proposed that they should be driven into the alleged ranks of homosexuals, something they resent most scornfully. In both cases we see a peculiar psychic process which must be conceived as a projection to the surroundings, to the world of external reality, of unconscious subjective notions. When an individual breaks down mentally complaining to be a victim of watchfulness and persecution for alleged homosexual purposes, the condition may be explained only in the sense that the individual in question actually harbors within himself a powerful homosexual tendency and the latter is projected unto the world of external reality through a peculiar mental mechanism. The old proposition: _ex nihilo nihil fit_ holds true also of the mental sphere and it would be utterly unscientific to fail to recognize in this sphere as well the law of strict causality or motivation. A careful examination of the mental life of our insane man’s unconscious shows that homosexuality is a powerful motive force much more frequently than is ordinarily recognized and this attempt to turn the unconscious subjective feeling of homosexuality into an objective reality, constitutes a pathway for the release of inner psychic tension, so a means for the individual to escape the feeling of guilt roused by his erroneous perception of facts and to pass the responsibility onto other shoulders. Many of the insane notions of our patients become intelligible and we grasp their meaning only when we recognize the powerful rôle which homosexuality plays in man’s unconscious.” _Juliusburger_ also recognizes the significance of sadism and its tremendous rôle in the psychogenesis of the delusion of jealousy. In his contribution referred to previously, “_Zur Psychologie des Alkoholismus_” (_Zentralblatt f. Psychoanalyse_, Vol. III, 1913), he makes the following relevant observations:
