ABSTRACT
As I stated at the beginning of this thesis, I was fortunate in gaining a new series of observations in one of my patients; I was also led to see the part played by unconscious factors in this same subject. I shall, therefore, at this stage, proceed to give some details of the observations recorded. I was fortunate, in the case I am about to relate, in being able to elicit the history of a continued change gradually taking place. The case was that of a patient who had gradually substituted fore-pleasure for end-pleasure in a large number of spheres of activity. That is to say, he substituted psychic discharges for physical discharges of tension, and in order to lengthen his period of psychic fore-pleasure, he postponed the discharge of physical tension by deliberately adding stimuli to protract the tension indefinitely.
