Still we are not at the end of the psychotherapeutic methods and we may turn to a fascinating group of curative efforts which has especially come to the foreground in recent years. We mentioned before that mischief cannot seldom be traced back to earlier experiences with a strong unpleasurable feeling. In certain cases, the subject remembers such particular experiences as the beginning of his discomfort; in others, especially those of hysteric character, the starting point may have long been forgotten, and yet that early impression evidently left traces in the brain which produce disturbances in conscious life. The psychotherapist nowadays calls these groups of traces "complexes." We recognized clearly that there is no reason to refer such forgotten remainders of the past to any subconscious mind; they are physical after-effects which keep their influence over the equilibrium of the psychophysical system. Now modern psychotherapy finds that the entire disturbances which arise from such emotional disagreeable experiences, forgotten or not forgotten, can often be removed by psychical means. Two ways in particular seem open. As soon as the idea is fully brought back to consciousness again, the patient must be made to express the primary emotion with full intensity. Subtle analysis has repeatedly shown that many of the gravest hysteric symptoms result from such a suppression of emotions at the beginning and disappear as soon as the primary experience comes to its right motor discharge and gains its normal outlet in action. The whole irritation becomes eliminated, the emotion is relieved from suppression and the source of the cortical uproar is removed forever. Practically still more important seems the other case which refers alike to hysterics and psychasthenics and which is applicable for the forgotten experience not less than for the well-remembered ones. This second way demands that the psychotherapist bring this primary experience strongly to consciousness and then by a new training link it with new and more desirable associations and reactions. The disturbing idea is thus not to be discharged but to be sidetracked so that in future it leads to harmless results. The new setting works towards an entirely new equilibrium. What was a starting point for abnormal fears now becomes an indifferent object of interest and all its evil consequences are cut off. It may be acknowledged that the full elaboration of these methods still belongs to the future. Both methods, the discharging, or the so-called cathartic one, and the side-tracking method evidently demand the discovery of the starting point in the service of the therapy and here again several methods are at the disposal of the psychologist.
