reflection, and not to the original force to which it owed its strength and which, unimpeachable, lay buried in the unconscious. Let us now piece together these fragments to see what a short and impeded psychoanalysis can nevertheless contribute to the understanding of this case. It is assumed of course that our inquiries were carefully conducted, a point which I cannot at this place submit to your judgment. In the first place, the obsession becomes no longer nonsensical nor incomprehensible, it is full of meaning, well motivated and an integral part of the patient's emotional experience. Secondly, it is a necessary reaction toward an unconscious psychological process, revealed in other ways, and it is to this very circumstance that it owes its obsessional nature, that is, its resistance to arguments based on logic or fact. In itself the obsession is something wished for, a kind of consolation. Finally, the experiences underlying the condition are such as unmistakably determine an obsession of jealousy and no other. You will also recognize the part played by the two important analogies in the analysis of the symptomatic act with reference to its meaning and intent and also to its relation to an unconscious factor in the situation. Naturally, we have not yet answered all the questions which may be put on the basis of this case. Rather the case bristles with further problems of a kind which we have not yet been able to solve in any way, and of others which could not be solved because of the disadvantage of the circumstances under which we were working. For example: why is this happily married woman open to an infatuation for her son-in-law, and why does the relief which could have been obtained in other ways come to her by way of this mirror-image, this projection of her own condition upon her husband? I trust you will not think that it is idle and wanton to open such problems. Already we have much material at our disposal for their possible solution. This woman is in that critical age when her sexual needs undergo a sudden and unwelcome exaggeration. This might in itself be sufficient. In addition, her good and faithful mate may for many years have been lacking in that sufficient sexual capacity which the well-preserved woman needs for her satisfaction. We have learned by experience to know that those very men whose faithfulness is thus placed beyond a doubt are most gentle in their treatment of their wives and unusually forbearing toward their nervous complaints. Furthermore, the fact that it was just the young husband of a daughter who became the object of her abnormal infatuation is by no means insignificant. A strong erotic attachment to the daughter, which in the last analysis leads back to the mother's sexual constitution, will often find a way to live on under such a disguise. May I perhaps remind you in this connection that the relationship between mother and son-in-law has
