From all these the thought of defense resulted as if simultaneously. Indeed, it is generally admitted by all psychologists that the assumption of a new idea (assumption in the sense of belief, judgment of reality), depends on the mode and drift of the ideas already united in the ego. For the process of the censor, to which the newly formed ideas are subjected, special technical names have been created. An idea entered into the ego of the patient which proved to be unbearable and evoked a power of repulsion on the part of the ego, the purpose of which was a defense against this unbearable idea. This defense actually succeeded, and the idea concerned was crowded out of consciousness and out of the memory, so that its psychic trace could not apparently be found. Yet this trace must have existed. When I made the effort to direct the attention to it, I perceived as a resistance the same force which showed itself as repulsion in the genesis of the symptom. If I could now make it probable that the idea became pathogenic in consequence of the exclusion and repression, the chain would seem complete. In many epicrises of our histories, and in a small work concerning the defense neuropsychoses (1894), I have attempted to indicate the psychological hypotheses with the help of which this connection also—the fact of conversion—can be made clear. Hence, a psychic force, the repugnance of the ego, has originally crowded the pathogenic idea from the association, and now opposes its return into the memory. The not knowing of the hysterics was really a—more or less conscious—not willing to know, and the task of the therapeutist was to overpower this resistance of association by psychic labor. Such accomplishment is, above all, brought about by “urging,” that is, by applying a psychic force in order to direct the attention of the patient on the desired traces of ideas. It does not, however, stop here, but as I will show, it assumes new forms in the course of the analysis, and calls to aid more psychic forces. I shall, above all, still linger at “the urging.” One cannot go very far with such simple assurances as, “You do know it, just say it,” or “It will soon come to your mind.” After a few sentences the thread breaks, even in the patient who is in a state of concentration. We must not, however, forget that we deal everywhere here with a quantitative comparison, with the struggle between motives of diverse force and intensity. The urging of the strange and inexperienced physician does not suffice for the “association resistance” in a grave hysteria. One must resort to more forceful means.
