My investigations of the traumatic neuroses in peace time had for a long time led me to conclude the importance of sexuality in them similar to that in the other neuroses, but they have not yet been sufficiently numerous and conclusive enough for publication. I might mention the case of a young girl who met with a slight tram accident when she was in the throes of a serious erotic conflict. The analysis showed that the accident in a certain measure gave a pretext for the outbreak of the neurosis. The symptoms were in connection with the conflict in question; the importance of the trauma receded quite into the background. I might also add that some litigious cases of traumatic neurosis which I observed in greater detail all suffered from impotence; this disturbance was produced by the accident, but seemed to have its real basis in old and unconscious sexual resistances. The investigation of war neurotics has fully confirmed my surmises connected with such observations. Moreover, the recurrence of certain definite symptoms in war neurotics, which were familiar to me not only in the traumatic neuroses of peace time, but also in the non-traumatic cases, seems to me worth noting. I refer particularly to the complex of symptoms which we could so often observe during the war in the anxiety cases with trembling, such as trembling, agitation, irritability, sensitiveness, sleeplessness, headaches, anxiety, depression of spirits and feelings of incompetency. Two neurotic types with the same symptoms—although these do not appear so prominently as in the war—would be the impotent man and the frigid woman. A similarity which is so marked in external phenomena leads one to expect a similarity also in internal processes. All my experience fully coincides with that which Ferenczi has just communicated. The trauma acts on the sexuality of many persons in the sense that it gives the impulse to a regressive alteration which endeavours to reach narcissism. I might add that we both arrived at this idea without having previously even mentioned it to one another. The trauma, however, has this effect only in a portion of those participating in the war, hence we are unable to dispense with the assumption of an individual disposition, but we are in the position to define it far more accurately than the prevailing school of neurology. A couple of examples will make the problem before us clearer.
