Birnbaum showed in his excellent summary of the literature of the traumatic neuroses that in many of the explanations of these neuroses (for example, in Strümpell’s theory of covetousness) is summed up a psychogenic wish of hysteria, and says: “If the psychogenic wish, the wish fixation, etc. is an essential component of hysteria then it belongs unconditionally in the definition of the disorder”. Psycho-analysis has long maintained this; as is well known, it regards the neurotic symptoms as expressions of unconscious wishes or as reactions to them.

Vogt also refers to the “famous Freudian statement” according to which the troubled mind flies into illness and he acknowledges that “the compulsion which originates from this is more often unconscious than conscious”. Liepmann divides the symptoms of the traumatic neuroses into the direct results of the psychic trauma and into “finally adjusted psychic mechanisms”. Schuster speaks of symptoms which are evoked by means of “unconscious processes”.

You see, therefore, ladies and gentlemen, that the experiences among war neurotics gradually led further than to the discovery of the mind; they led neurologists very nearly to the discovery of psycho-analysis. When we read in the more recent literature on the subject, of the ideas and views which have become so familiar,—abreaction, unconscious, psychic mechanisms, separation of the affect from its idea, etc.,—we might easily imagine ourselves to be in a circle of psycho-analysts, and yet it has never occurred to these investigators to ask themselves whether, after these experiences in the war neuroses, the psycho-analytical concepts cannot be made use of in the explanation of the usual neuroses and psychoses which were well known to us in peace times. The specificity of the war trauma is universally denied; in general, it is said, that the war neuroses contain nothing and have added nothing new to the already known symptomatology of the neuroses; even the Munich Congress of German Neurologists formally demanded the elimination of the word and concept, “war neurosis”. If, however, the peace and war neuroses are identical in their nature, then neurologists will be obliged to make use of all these ideas of emotional shock, of the fixation of pathogenic memories, and of their continued activity in the unconscious, etc., also in the explanation of the usual hysterias, the obsessional neuroses and the psychoses. They will be astonished how easy it will be for them to traverse the path trodden by Freud, and will regret having shown such obstinate resistance to his hints.

To the question of the disposition to fall sick with a war neurosis the authors gave contradictory answers. Most of them follow the views of Gaupp, Laudenheimer and others, according to whom most of the war neurotics are ab ovo neuropaths or psychopaths, the shock merely playing the part of the releasing factor. Bonhoeffer says direct: “The possibility of a psychopathological condition being evoked by psychogenic factors is the criterion of a degenerative predisposition”. Forster and Jendrassik say the same thing. Nonne, on the contrary, finds that the deciding factor in falling a victim to war neuroses lies less in the personal constitution than in the nature of the operating injury. Psycho-analysis takes a median position with regard to this question, which Freud has frequently and expressly stated. It speaks of an “aetiological succession” in the predisposition, the traumatic occasion figuring as reciprocal value with this. A trifling predisposition and severe shock can produce the same effects as an increased predisposition and a much lesser degree of shock. Psycho-analysis, however, is not content with the theoretical allusion to this condition, but it endeavours—with success—to separate the complex idea of the “disposition” into simpler elements and establish those constitutional factors that influence the choice of neurosis (the special tendency to fall sick with this or that neurosis). I shall return later to the question as to where psycho-analysis looks for the special disposition to falling sick with a traumatic neurosis.

The literature concerning the symptomatology of the neuroses of the war is simply immense. According to Gaupp, for example, the following hysterical symptoms are to be observed. “Attacks of a slight nature up to those of the severest kind, with an arc de cercle lasting for hours, sometimes with epileptic frequency, astasia-abasia, anomalies of the position and movement of the body even to going on all fours, all the varieties of tic and shaking tremors, paralyses and contractures in monoplegic, hemiplegic and paraplegic forms, deafness and deaf and dumbness, stuttering and stammering, aphonia and rhythmical screaming, blindness with or without blepharo-spasm, all kinds of disturbances of sensation, and most of all twilight states in quantities never before met with and in combination with phenomena of physical irritation and disorders”. You see, it is like a museum of glaring hysterical symptoms, and whoever has once seen it will plainly have to decline Oppenheim’s view, according to which purely neurotic symptoms are rarely seen in the traumatic neuroses of the war. Schuster draws attention to the frequent vasomotor and trophic phenomena; according to him, these are no longer psychogenic. Psycho-analysis, however, will agree with those who hold that these symptoms can originate to some extent from psychic causes, analogous to the physical alterations which can be produced under hypnosis. Finally, all the authors allude to the alterations in disposition, apathy and over-excitability, etc. after the trauma.

Out of this chaos of symptoms the “trembling” neurosis stands out through its frequency and conspicuousness. You all know those pathetic creatures who hobble along through the streets with shaking knees, uncertain gait and peculiar motor disturbances. They give the impression of being helpless and incurable invalids; and yet experience shows that also this traumatic form of illness is purely psychogenic. A single treatment with electricity and suggestion, a few hypnotic sittings are often sufficient in rendering these men capable of doing some work, if only temporarily and under certain conditions. Erben has made the most careful investigation into these disturbances of innervation; he found that these disturbances are only suspended or increased when the respective group of muscles carry out an action or intend to do so. His explanation for this is, that here the “volitional impulse makes a path for the spasm”, which, however, is only the physiological paraphrase of the facts of the case. Psycho-analysis suspects here a psychical motivation: the activity of an unconscious contrary wish which puts itself in the way of the consciously wished act. This is indeed most striking in those patients of Erben who are prevented from going forward through the most violent attacks of shaking, but can carry out the much more difficult task of going backwards without trembling. Erben also here has a complicated physiological explanation ready, but forgets that the movement backwards, which removes the patient from the dangerous goal of the forward movement—and finally from the front line—does not need to be disturbed by any contrary wish. The remaining kinds of motor disturbances demand a similar interpretation, in particular the striking, uncontrollable running of many neurotics, so like the propulsion in paralysis agitans. These are the men who do not recover from the effect of the terror and are still always flying from dangers to which they were once exposed.

Many investigators, including non-psycho-analysts, came to the conclusion from these and similar observations, that these disturbances are not the direct effects of the trauma, but psychical reactions to it and act in the service of the instinct of self-preservation against the repetition of the unpleasant occurrence. We know that also the normal organism has at its disposal such protective measures. The symptoms of the terror, such as the immovable legs, the tremblings, the hesitating speech, seem to be useful automatisms; one is reminded by them of certain animals which simulate being dead when danger threatens. And if Bonhoeffer looks upon these traumatic disturbances as fixations of the means of expression of the terrible emotion which has been suffered, Nonne goes further and discovers that “the hysterical symptoms represent partly a reminiscence of inborn guard and defence mechanisms, the suppression of which in those individuals whom we call hysterical has not taken place in the normal degree or not at all”. According to Hamburger the most frequently occurring type of disturbances of standing, walking and speech associated with shaking tremors represents a “complex of ideas of feebleness, weakness, refusal and exhaustion”, and Gaupp sees in the same symptoms the lapse into infantile and puerile states of obvious helplessness. Some authors actually speak of the “fixation” in the traumatic posture of the body and innervation.

It cannot escape the notice of anyone with a knowledge of psycho-analysis how near these authors, without knowing it, are to psycho-analysis. The “expressions of fixations of movements” described by them are in reality only paraphrases of the Breuer-Freudian hysterical conversion, and the lapse into atavistic and infantile methods of reaction is nothing more nor less than what Freud called special attention to as the regressive character of the neurotic symptoms, all of which according to him only signify reversions into ontogenetic and phylogenetic stages of development already overcome. At any rate we have definite proof that neurologists have now decided to interpret certain nervous symptoms, that is to say, refer them to unconscious psychical contents, which would never have occurred to anyone to do before the introduction of psycho-analysis.

I will now speak of the few authors who occupy themselves with the war neuroses from the psycho-analytical points of view.
