You will remember that in the two cases in which we submitted the symptoms to detailed investigation analysis led to the innermost secrets of the patient’s sexual life. In the first case, moreover, the purpose or tendency of the symptom under examination was particularly evident; in the second case, it was perhaps to some extent veiled by another factor to be mentioned later. Well now, what we found in these two examples we should find in every case we submitted to analysis. Every time we should be led by analysis to the sexual experiences and desires of the patient, and every time we should have to affirm that the symptom served the same purpose. This purpose shows itself to be the gratification of sexual wishes; the symptoms serve the purpose of sexual gratification for the patient; they are a substitute for satisfactions which he does not obtain in reality. Think of the obsessive act of our first patient. This woman has to do without the husband she loved so intensely; on account of his deficiencies and short-comings she could not share his life. She had to be faithful to him; she could not put anyone else in his place. Her obsessional symptom gives her what she so much desires; it exalts her husband, denies and corrects his deficiencies, above all, his impotence. This symptom is fundamentally a wish-fulfilment, in that respect exactly like a dream; it is, moreover, what a dream is not always, an erotic wish-fulfilment. In the case of the second patient you could see that her ritual aims at preventing intercourse between the parents or at hindering the procreation of another child; you have probably also divined that fundamentally it seeks to set her in her mother’s place. It again therefore constitutes a removal of hindrances to sexual satisfaction and the fulfilment of the subject’s own sexual wishes. Of the complications referred to in the second case I shall speak shortly.
