I, therefore, find it important to separate the hysterical part in the pictures of the mixed neuroses from neurasthenia, anxiety neurosis, etc., for after this separation I can express concisely the therapeutic value of the cathartic method. I would venture to assert that—principally—it can readily dispose of any hysterical symptom, whereas, as can be easily understood, it is perfectly powerless in the presence of neurasthenic phenomena, and can only seldom, and through detours, influence the psychic results of the anxiety neurosis. Its therapeutic efficacy in the individual case will depend on whether or not the hysterical components of the morbid picture can claim a practical and significant position in comparison to the other neurotic components. Another limitation placed on the efficacy of the cathartic method we have already mentioned in our “Preliminary Communication.” It does not influence the causal determinations of hysteria, and hence it can not prevent the origin of new symptoms in the place of those removed. Hence, on the whole, I must claim a prominent place for our therapeutic method in the realm of the therapy of neuroses, but I would caution against attaching any importance to it, or putting it into practice outside of this connection. As I am unable to give here a “Therapy of Neuroses” as would be required by the practicing physician, the preceding statements are put on a level with the deferred reference to a later communication; still, for purposes of discussion and elucidation, I can add the following remarks: 1. I do not claim that I have actually removed all the hysterical symptoms which I have undertaken to influence by the cathartic method, but I believe that the obstacles were due to the personal circumstances of the cases, and not to the general principles. In passing sentence, these cases of failure may be left out of consideration, just as the surgeon puts aside all cases who die as a result of narcosis, hemorrhage, accidental sepsis, etc., when deciding upon a new technique. I will again consider the failures of such origin in my later discussions on the difficulties and drawbacks of this method. 2. The cathartic method does not become valueless simply because it is symptomatic and not causal. For a causal therapy is really in most cases only prophylactic; it stops the further progress of the injury, but it does not necessarily remove the products which have already resulted from it. To do this it requires, as a rule, a second agent, and in cases of hysteria the cathartic method is really unsurpassable for such purposes.
