GENERAL THEORY OF THE NEUROSES
You are, however, justified in expecting some interest on our part in the true neuroses. Because of their intimate connection with psychoneuroses we find this decidedly necessary. I shall tell you then that we distinguish three pure forms of true neuroses: _neurasthenia_, _anxiety neurosis_ and _hypochondria_. Even this classification has not remained uncontradicted. The terms are all widely used, but their connotation is vague and uncertain. Besides, there are in this world of confusion physicians who object to any distinctions between manifestations, any emphasis of clinical detail, who do not even recognize the separation of true neuroses and psychoneuroses. I think they have gone too far and have not chosen the road which leads to progress. The types of neuroses we have mentioned occur occasionally in pure form; more often they are blended with one another or with a psychoneurotic condition. This need not discourage us to the extent of abandoning the task of distinction. Think of the difference between the study of minerals and that of ores in mineralogy. Minerals are described as individuals; frequently of course they occur as crystals, separated sharply from their surroundings. Ores consist of an aggregate of minerals which have coalesced not accidentally, but as a result of the conditions of their origin. We understand too little of the process of development of neuroses, to create anything similar to the study of ores. But we are surely working in the right direction when we isolate the known clinical factors, comparable to the separate minerals, from the great mass.
A noteworthy connection between the symptoms of the true neuroses and the psychoneuroses adds a valuable contribution to our knowledge of symptom formation in the latter. The symptom in the true neuroses is frequently the nucleus and incipient stage of development of the psychoneurotic symptom. Such a connection is most easily observed between neurasthenia and the transference neuroses, which are termed conversion hysteria, between anxiety neurosis and anxiety hysteria, but also between hypochondria and paraphrenia (dementia praecox and paranoia), forms of neuroses of which we shall speak subsequently. Let us take as an illustration the hysteric headache or backache. Analysis shows that through elaboration and displacement this pain has become the gratification substitute for a whole series of libidinous phantasies or reminiscences. But once upon a time this pain was real, a direct sexual toxic symptom, the physical expression of libidinous excitation. We do not wish to assert, by any means, that all hysteric symptoms can be traced to such a nucleus, but it is true that this is frequently the case, and that all influences upon the body through libidinous excitation, whether normal or pathological, are especially significant for the symptom development in hysteria. They play the part of the grain of sand which the mollusc has enveloped in mother-of-pearl. In the same way passing signs of sexual excitation, which accompany the sexual act, are used by psychoneurosis as the most convenient and appropriate material for symptom formation.
A similar procedure is of diagnostic and therapeutic interest especially. Persons who are disposed to be neurotic, without suffering from a flourishing neurosis, frequently set in motion the work of symptom development as the result of an abnormal physical change--often an inflammation or an injury. This development rapidly makes the symptom given by reality the representative of the unconscious phantasies that had been lurking for an opportunity to seize upon a means of expression. In such a case the physician will try different ways of therapy. Either he will try to do away with the organic basis without bothering about its noisy neurotic elaboration, or he will struggle with the neurosis brought out by the occasion, and ignore its organic cause. The result will justify now one, now the other method of procedure; no general laws can be laid down for such mixed cases.
