It is scarcely accidental that the numerous examples of forgetting which have been collected without any selection should require for their solution the introduction of such painful themes as exposing of one’s wife; a friendship that has turned into the opposite; a mistake in medical diagnosis; enmity on account of similar pursuits, or the borrowing of somebody’s ideas. I am rather inclined to believe that every person who will undertake an inquiry into the motives underlying his forgetting will be able to fill up a similar sample card of vexatious circumstances. The tendency to forget the disagreeable seems to me to be quite general; the capacity for it is naturally differently developed in different persons. Certain _denials_ which we encounter in medical practice can probably be ascribed to _forgetting_.[32] Our conception of such forgetting confines the distinction between this and that behaviour to purely psychologic relations, and permits us to see in both forms of reaction the expression of the same motive. Of the numerous examples of denials of unpleasant recollection which I have observed in kinsmen of patients, one remains in my memory as especially singular. A mother telling me of the childhood of her nervous son, now in his puberty, made the statement that, like his brothers and sisters, he was subject to bed-wetting throughout his childhood, a symptom which certainly has some significance in a history of a neurotic patient. Some weeks later, while seeking information regarding the treatment, I had occasion to call her attention to signs of a constitutional morbid predisposition in the young man, and at the same time referred to the bed-wetting recounted in the anamnesis. To my surprise she contested this fact concerning him, denying it as well for the other children, and asked me how I could possibly know this. Finally I let her know that she herself had told me a short time before what she had thus forgotten.[33]
