I think it worth emphasizing that with all changes my ideas on the etiology of the psychoneuroses still never disavowed or abandoned two points of view, to wit, the estimation of sexuality and infantilism. In other respects we have in place of the accidental influences the constitutional moments, and instead of the pure psychologically intended defense we have the organic “sexual repression.” Should anybody ask where a cogent proof can be found for the asserted etiological significance of sexual factors in the psychoneuroses, and argue that since an outburst of these diseases can result from the most banal emotions, and even from somatic causes, a specific etiology in the form of special experiences of childhood must therefore be disavowed; I mention as an answer for all these arguments the psychoanalytic investigation of neurotics as the source from which the disputed conviction emanates. If one only makes use of this method of investigation he will discover that the symptoms represent the whole or a partial sexual manifestation of the patient from the sources of the normal or perverse partial impulses of sexuality. Not only does a good part of the hysterical symptomatology originate directly from the manifestations of the sexual excitement, not only are a series of erogenous zones in strengthening infantile attributes raised in the neurosis to the importance of genitals, but even the most complicated symptoms become revealed as the converted representations of fancies having a sexual situation as a content. He who can interpret the language of hysteria can understand that the neurosis only deals with the repressed sexuality. One should, however, understand the sexual function in its proper sphere as circumscribed by the infantile predisposition. Where a banal emotion has to be added to the causation of the disease, the analysis regularly shows that the sexual components of the traumatic experience, which are never missing, have exercised the pathogenic effect.
