I regret to have to omit many interesting details from the analysis of this case. To me the analysis of this case has been a revelation. For a number of years past I have been intensely interested in the problem of recidivism, and although I have had many opportunities to study the recidivist, and have seen a number of very interesting cases, the histories of a few of whom I have reported several years ago, I have always felt that I had never touched the real specific cause of a life of recidivism in a given individual. Why a man, an apparently intelligent man, and many of them are far from suffering from a purely intellectual defect, should choose a career of crime and in spite of repeated penalties should keep on recurring to it, has always been an unsolved mystery to me. I have been especially perplexed about those cases which repeatedly committed the same crime, and although in some instances an apparently plausible explanation was found in an existing psychosis, or strong psychopathic make-up, these explanations were in many instances unsatisfactory. Let us see what the repeated commission of theft means to the individual whose history we have just reported. We have seen that his own explanation of that series of physical and mental phenomena which always accompanied the act of stealing were not only very much akin to the physical and mental state which accompanies the act of sexual congress, but were actually recognized as such by the man himself. In other words the motive and instinctive prompting which led this man to the act of stealing were the same which lead normal men to the act of sexual congress. It would be inconceivable without further explanation why this colored boy should repeatedly resort to stealing as a means of sexual gratification in spite of the trials and tribulations which this carried with it, when he had all the opportunities to gratify this desire in a natural heterosexual manner, as others of his race have no difficulty at all in doing. The answer lies in the type of sexual gratification which his stealing supplied. We have mentioned the anal sensations, the feeling as though there was something in the rectum of which he had to rid himself, and which for years led him to run to the toilet soon after the commission of a theft. To one versed in the psychology and manifestations of the sex instinct this can only mean one thing, namely, that we are dealing here with a homosexual whose erotic receptors were concentrated in the anal region, with an anal-erotic.
