This period is brought to an end by the appearance of the—often self ripened—sexual “maturity.” A reproach then attaches itself to the memory of that pleasurable action, and the connection with the initial experience of passivity makes it possible—often only after conscious and recollected effort—to repress it and replace it by a primary symptom of defense. The third period, that of apparent healthiness but really of successful defense, begins with the symptoms of scrupulousness, shame and diffidence. The next period, the disease is characterized by the return of the repressed reminiscences, hence, by the failure of the defense; but it remains undecided whether the awakening of the same is more frequently accidental and spontaneous, or whether it appears in consequence of actual sexual disturbances, that is, as additional influences of the same. But the revived reminiscences and the reproaches formed from them never enter into consciousness unchanged, but what becomes conscious as an obsession and obsessive affect and substitutes the pathogenic memory in the conscious life, are compromise formations between the repressed and the repressing ideas. In order to describe clearly and probably convincingly the processes of repression, the return of the repression, and the formation of the pathological ideas of compromise, we would have to decide upon very definite hypotheses concerning the substratum of the psychic occurrence and consciousness. As long as we wish to avoid it we will have to rest content with the following rather figuratively understood observations. Depending on whether the memory content of the reproachful action alone forces an entrance into consciousness or whether it takes with it the accompanying reproachful affect, we have two forms of compulsion neurosis. The first represents the typical obsessions, the content of which attracts the patient’s attention; only an indefinite displeasure is perceived as an affect, whereas, for the content of the obsession the only suitable affect would be one of reproach. The content of the obsession is doubly distorted when compared to the content of the infantile compulsive act. First, something actual replaces the past experience, and second, the sexual is substituted by an analogous non-sexual experience. These two changes are the results of the constant tendency to repression still in force which we will attribute to the “ego.” The influence of the revived pathogenic memory is shown by the fact that the content of the obsession is still partially identical with the repressed, or can be traced to it by a correct stream of thought. If, with the help of the psychoanalytic method, we reconstruct the origin of one individual obsession we find that one actual impression instigated two diverse streams of thought, and that the one which passed over the repressed memory, though incapable of consciousness and correction, proves to be just as correctly formed logically as the other.
