As to the neurotic symptoms, we already know that they are the result of a conflict aroused by a new form of gratifying the libido. The two forces that have contended against each other meet once more in the symptom; they become reconciled through the compromise of a symptom development. That is why the symptom is capable of such resistance; it is sustained from both sides. We also know that one of the two partners to the conflict is the unsatisfied libido, frustrated by reality, which must now seek other means for its satisfaction. If reality remains inflexible even where the libido is prepared to take another object in place of the one denied it, the libido will then finally be compelled to resort to regression and to seek gratification in one of the earlier stages in its organizations already out-lived, or by means of one of the objects given up in the past. Along the path of regression the libido is enticed by fixations which it has left behind at these stages in its development. Here the development toward perversion branches off sharply from that of the neuroses. If the regressions do not awaken the resistance of the ego, then a neurosis does not follow and the libido arrives at some actual, even if abnormal, satisfaction. The ego, however, controls not alone consciousness, but also the approaches to motor innervation, and hence the realization of psychic impulses. If the ego then does not approve this regression, the conflict takes place. The libido is locked out, as it were, and must seek refuge in some place where it can find an outlet for its fund of energy, in accordance with the controlling demands for pleasurable gratification. It must withdraw from the ego. Such an evasion is offered by the fixations established in the course of its evolution and now traversed regressively, against which the ego had, at the time, protected itself by suppressions. The libido, streaming back, occupies these suppressed positions and thus withdraws from before the ego and its laws. At the same time, however, it throws off all the influences acquired under its tutelage. The libido could be guided so long as there was a possibility of its being satisfied; under the double pressure of external and internal denial it becomes unruly and harks back to former and more happy times. Such is its character, fundamentally unchangeable. The ideas which the libido now takes over in order to hold its energy belong to the system of the unconscious, and are therefore subject to its peculiar processes, especially elaboration and displacement. Conditions are set up here which are entirely comparable to those of dream formation. Just as the latent dream, the fulfillment of a wish-phantasy, is first built up in the unconsciousness, but must then pass through conscious processes before, censored and approved, it can enter into the compromise construction of the manifest dream, so the ideas representing the libido in the
