A better description of this peculiar state in which one knows something and at the same time does not know it, I could never obtain. It can apparently be understood only if one has found himself in such a state. I have at my disposal a very striking recollection of this kind which I can vividly see. If I make the effort to recall what passed through my mind at that time my output seems very poor. I saw at that time something which was not at all appropriate to my expectations, and what I saw did not in the least divert me from my definite purpose, whereas this perception ought to have done away with my purpose. I did not become conscious of this contradiction nor did I remark the affect of the repulsion to which it was undoubtedly due that this perception did not attain any psychic validity. I was struck with that form of blindness in seeing eyes, which one admires so much in mothers towards their daughters, in husbands towards their wives, and in rulers towards their favorites.

Footnote 19: To my surprise I once discovered that such subsequent ab-reaction—through other impressions than nursing—may form the content of an otherwise enigmatic neurosis. It was the case of a pretty girl of nineteen, Miss Matilda H. whom I first saw with an incomplete paralysis of the legs, and months afterward I was again called because her character had changed. She was depressed and tired of living, entertaining lack of consideration for her mother, and was irritable and inapproachable. The whole picture of the patient did not seem to me to be that of an ordinary melancholia. She could easily be put into a somnambulic state, and I made use of this peculiarity to impart to her each time commands and suggestions to which she listened in her profound sleep and responded with profuse tears, but which, however, caused but little change in her condition. One day while hypnotized she became talkative and informed me that the reason for her depression was the breaking of her betrothal many months before. She stated that on closer acquaintance with her fiance the things displeasing to her and her mother became more and more evident. On the other hand, the material advantages of the engagement were too tangible to make the decision of a rupture easy, thus, both of them hesitated for a long time. She then merged into a condition of indecision in which she allowed everything to pass apathetically, and finally her mother pronounced for her the decisive “no.” Shortly after, she awoke as from a dream and began to occupy herself fervently with the thoughts about the broken betrothal, she began to weigh the
