Human experience and schemes of personal behavior are the most interesting of all themes, as is evidenced by fiction, the drama, biographies, and histories. And works of this kind contain materials which will be given a scientific value as we analyze, compare, and interpret them. Even fictitious representations are significant when viewed as showing the tendency at a given moment to idealize certain schematizations of life. The autobiography has a more positive value for the student, but usually tends to approach the model of fiction, idealizing certain situations and experiences and repressing others totally. Incidentally one of the largest and most important bodies of spontaneous material for the study of the personality and the wishes passes through the mails. The letters of the Bedford girl, for example (document No. 86, p. 172) appeal to me as the most significant document in this volume, in spite of the fact that they relate to one incident and cover a relatively short time. The short life-histories of approximately six thousand Jews printed in the New York _Forward_, and representing the effort to find new definitions of new situations on the part of the million and a half Jewish immigrants in New York City, and to some extent of the three million Jews in America, are a rich contribution to the study of the wishes. These records, hidden from the eye of the “_goi_” behind the Hebrew alphabet, have the intimacy and naïveté of personal confessions. Another type of behavior record is now being prepared by those social workers, psychologists, and psychiatrists who have to handle the problems of maladjustment in the courts, schools, and reformatories and in private practice. Under the pressure of practical needs they have already assumed the standpoint I have outlined and are studying the evolution of personal life-organization and making the record as complete as possible. They meet the individual at the point of some crisis, some experience or breakdown calling for readjustment, but from this point they work backward into the history of the case and follow its development into the future. In the beginning they over-determined the value of the psychometric test, because this was the only method psychology had put in their hands, but at present the measurement of intelligence is recognized as having a limited usefulness. “Feeble-mindedness” is partly a classificatory term for those personalities whose behavior we have not been able to conform to the usual standards because of lack of knowledge and method. We shall not know what conditions to call feeble-minded until we have determined the limits of the social influences which we can apply. Certain social workers are taking case after case pronounced subnormal by the clinicists and developing in them activities which enable them to live in a society where they could not live before, while a large proportion of those now pursuing peaceful callings would be called morons if they
