(_f_) That accidental actions are really intentional will find no greater credence in any other sphere than in sexual activity, where the border between the intention and accident hardly seems discernible. That an apparently clumsy movement may be utilized in a most refined way for sexual purposes I can verify by a nice example from my own experience. In a friend’s house I met a young girl visitor who excited in me a feeling of fondness which I had long believed extinct, thus putting me in a jovial, loquacious, and complaisant mood. At that time I endeavoured to find out how this came about, as a year before this same girl made no impression on me. As the girl’s uncle, a very old man, entered the room, we both jumped to our feet to bring him a chair which stood in the corner. She was more agile than I and also nearer the object, so that she was the first to take possession of the chair. She carried it with its back to her, holding both hands on the edge of the seat. As I got there later and did not give up the claim to carrying the chair, I suddenly stood directly back of her, and with both my arms was embracing her from behind, and for a moment my hands touched her lap. I naturally solved the situation as quickly as it came about. Nor did it occur to anybody how dexterously I had taken advantage of this awkward movement. Occasionally I have had to admit to myself that the annoying, awkward stepping aside on the street, whereby for some seconds one steps here and there, yet always in the same direction as the other person, until finally both stop facing each other, that this “barring one’s way” repeats an ill-mannered, provoking conduct of earlier times and conceals erotic purposes under the mask of awkwardness. From my psychoanalysis of neurotics I know that the so-called naïveté of young people and children is frequently only such a mask, employed in order that the subject may say or do the indecent without restraint. W. Stekel has reported similar observations in regard to himself: “I entered a house and offered my right hand to the hostess. In a most remarkable way I thereby loosened the bow which held together her loose morning-gown. I was conscious of no dishonourable intent, still I executed this awkward movement with the agility of a juggler.” (_g_) The effects which result from mistakes of normal persons are, as a rule, of a most harmless nature. Just for this reason it would be particularly interesting to find out whether mistakes of considerable importance, which could be followed by serious results, as, for example, those of physicians or druggists, fall within the range of our point of view.
