You are putting your finger just on the point, where new complications may arise. It is not always possible to be perfectly sure of such a case. The patient, in spite of displaying all the visible symptoms of neurosis, may actually be suffering from something else. The incipient stage of a mental disease, for example, or the beginning of a process destroying his brain. To distinguish between such symptoms is not always easy or possible. Responsibility for such a decision must naturally be assumed by the physician alone. And as mentioned before, it is not so easy for him. For the longest time, an ailment may appear absolutely harmless, until finally manifesting its malignant character. Nervous people, as a rule, fear that they may be on the road to some mental disease. Assumed that a physician has not correctly diagnosed a case, or has been unable to discover its true nature, nothing has been lost, no damage has been done. Analytical treatment, although not doing any harm to the patient, would have been superfluous in such a case. It might have given any number of people a chance to lay the blame for the unfortunate development of the case at the door of psychoanalysis. Unjustly so, to be sure, but such a likelihood should be avoided nevertheless. “That sounds hopeless. It apparently tears out, by the very roots, everything you told me about the nature and development of a neurosis.” Not at all. It only strengthens the fact that neurotics are a nuisance and a dilemma for all parties concerned, including the psychoanalysts. I may be able to alleviate your new apprehensions if I make myself clearer. Probably it would be more correct to say of such cases, as we now have under discussion, that they actually present neuroses. However, these neuroses are not psychic but rather somatic, that is, they do not originate from the soul, but rather from the body. Do you understand me? “I do. But I am at a loss to connect all this with the psychological aspect.” That can easily be done, if only complications of the living substance are sufficiently taken into consideration. What was the inherent feature of a neurosis? That the “I,” constituting the very essence of the soul, so to speak, developed and improved by the influence of the outer world, proved unable to fulfill its mediating functions between the “It” and reality; that the “I,” on account of its weakness, shirked its duties in regard to the “It,” thus incurring repressions from which it suffers. It is because such weakness of the “I” regularly takes place in all of us in childhood that events of our tender years exert such great importance in later life.
