I do not know, ladies and gentlemen, whether you also have obtained the impression from all these quotations and references (which are only taken at random from the literature) that an advance, even though one that is not admitted, has taken place in the attitude of leading neurologists towards the teachings of psycho-analysis. Moreover, candid recognition is not lacking; for example, the expression of Nonne, that Freud’s experiences concerning the elaboration in the unconscious have received interesting illuminations and corroborations through the experiences of the war. However, the same sentence of acknowledgement also contains a nihilistic opinion of Nonne concerning psycho-analysis; he states that Freud’s idea of the almost exclusively sexual foundation of hysteria has been conclusively disproved during the war. We can no longer leave this unanswered, which after all is only a partial denial of psycho-analysis: also we can very easily give the answer. The war neuroses, according to psycho-analysis, belong to a group of neuroses in which not only is the genital sexuality affected, as in ordinary hysteria, but also its precursor, the so-called narcissism, self-love, just as in dementia praecox and paranoia. I grant that the sexual foundation of these so-called narcissistic neuroses is less easily apparent, particularly to those who equate sexuality and genitality and have neglected to use the word “sexual” in the sense of the old platonic Eros. Psycho-analysis, however, returns to this extremely ancient standpoint when it treats all tender and sensual relations of the man to his own or to the opposite sex, emotional feelings towards friends, relatives and fellow-creatures generally, even the affective behaviour towards one’s own ego and body, partly under the rubric “erotism”, otherwise “sexuality”. It cannot be denied that those to whom this idea is strange cannot so easily be convinced of the correctness of Freud’s postulation of the sexual theory in a narcissistic neurosis in particular, for example, in the traumatic neurosis. We should like to advise them to examine themselves into the usual (non-traumatic) hysteria and obsessional neuroses also, and to keep strictly to the methods of free association, dream and symptom interpretation proposed by Freud; then they will be much more easily convinced of the correctness of the sexual theories of the neuroses, and agreement about the sexual background of the war neuroses will follow. At any rate the triumph concerning the overthrow of the sexual theories is somewhat premature.
