I place Nonne in the forefront of those authors who have laid particular stress on the psycho-genesis of the traumatic neuroses of the war. Not only because he recognised that the symptoms of the war shock neuroses were without exception hysterical, but because he was also able to cause the severest war neurotic symptoms to disappear for a time or to recall them by hypnotic and suggestive measures. This excluded the possibility even of a “molecular” disturbance in the nerve tissues; a disturbance that can be set right by means of psychic influences can itself have been nothing else than psychical. This therapeutic argument had the greatest effect; by degrees a marked silence fell over the mechanistic school, and attempts were frequently made to explain their former utterances psycho-genetically. The quarrel from now onwards lay entirely between the supporters of the various psychological theories. How is one to explain the method of working of psychical factors, and also the fact of the psychogenic condition being more severe than the impressive forms of disorders of organic origin? One is reminded of the old theory of Charcot, that terror and the memory of it can produce in a similar manner physical symptoms after the nature of hypnosis and auto-hypnosis, just as they are intentionally brought about by the post-hypnotic command of the hypnotist. This reverting to Charcot means nothing less than paving the way to fruitless speculations and the re-discovery of the sources from which finally psycho-analysis sprang; for we know that the first researches of Breuer and Freud into the psychical mechanisms of hysterical phenomena originated directly from the influence of Charcot’s clinical and experimental experiences. Hysterics suffer from reminiscences: this, the primary axiom of the germinating psycho-analysis, is really the continuation, deepening, and generalisation of the ideas of Charcot applied to the neuroses of shock; the idea of the lasting effect of a sudden affect and of the association of certain expressions of affect with the memory of the thing experienced is common to both. Let us now compare with this the views of German neurologists on the genesis of the war neuroses. Goldscheider says: “Sudden and terrifying impressions can leave behind affects direct and also with the associative help of ideation; to these memory pictures are due the results of increased and lowered excitability. Thus it is the emotion, the terror, which bestows upon the trauma the distribution and fixation of the nervous results of the stimulus, which never occurs with the purely physical stimulus itself”. It is easy to recognise that this description is borrowed from the traumatic theory of Charcot and the Freudian conversion theory.
