If the results of the two psychic operations disagree, the contradiction between the two may never be brought to logical adjustment, but as a compromise between the resistance and the pathological result of thought an apparently absurd obsession enters into consciousness beside the normal result of the thought. If both streams of thought yield the same result, they reinforce each other so that the normally gained result of thought now behaves psychically like an obsession. Wherever neurotic compulsion manifests itself psychically it originates from repression. The obsessions have, as it were, a psychical course of compulsion which is due, not to their own validity, but to the source from which they originate, or to the source which furnishes a part of their validity. A second form of compulsion neurosis results if the repressed reproach and not the repressed content of memory forces a replacement in the conscious psychic life. Through a psychic admixture, the affect of the reproach can change itself into any other affect of displeasure, and if this occurs there is nothing to hinder the substituting affect from becoming conscious. Thus, the reproach (of having performed in childhood some sexual actions) may be easily transformed into shame (if some one else becomes aware of it), into hypochondriacal anxiety (because of the physical harmful consequences of those reproachful acts), into social anxiety (fearing punishment from others), into religious anxiety, into delusions of observation (fear of betraying those actions to others), into fear of temptations (justified distrust in one’s own moral ability of resistance), etc. Besides, the memory content of the reproachful action may also be represented in consciousness, or it may be altogether concealed, which makes the diagnosis very difficult. Many cases which on superficial examination are taken as ordinary (neurasthenic) hypochondria often belong to this group of compulsive affects; the very frequently so called “periodic neurasthenia” or “periodic melancholia” especially seem to be explained by compulsive affects or obsessions, a recognition not unimportant therapeutically.
