In a predisposed person if there is no adaptation for conversion, and still for the purpose of defense a separation of the unbearable idea from its affect is undertaken, the affect must then remain in the psychic sphere. The weakened idea remains apart from all association in consciousness, but its freed affect attaches itself to other not in themselves unbearable ideas, which on account of this “false” connection become obsessions. This is in brief the psychological theory of the obsessions and phobias concerning which I have spoken above. I will now state what parts demanded in this theory can be directly demonstrated and what parts I have supplemented. Besides the end product of the process, the obsession, we can in the first place directly demonstrate the source from which the affect in the false connection originates. In all cases that I have analyzed it was the sexual life that has furnished a painful affect of precisely the same character as the one attached to the obsession. It is not theoretically excluded that this affect could not occasionally originate in other spheres, but I must say that thus far I have found no other origin. Moreover, one can readily understand that it is precisely the sexual life which furnishes the most manifold occasions for the appearance of unbearable ideas. Moreover, the exertion of the will, the attempt at defence, upon which this theory lays stress is demonstrated by the most unequivocal utterances of the patients. At least in a number of cases the patients themselves inform us that the phobia or obsession appeared only after the exertion of the will manifestly gained its point. “Something very disagreeable happened to me once and I have exerted all my power to push it away, not to think of it. When I have finally succeeded I have gotten the other thing instead, which I have not lost since.” With these words a patient verified the main points of the theory here developed. Not all who suffer from obsessions are so clear concerning the origin of the same. As a rule when we call the patient’s attention to the original idea of a sexual nature we receive the following answer: “It could not have come from that. Why I have not thought much about it. For a moment I was frightened, then I distracted myself and since then it has not bothered me.” In this, so frequent objection, we have the proof that the obsession represents a compensation or substitute for the unbearable sexual idea, and that it has taken its place in consciousness.
