The authors have had two major purposes, in writing this brief volume. They have, in the first place, attempted to formulate material for a college course which should give in vigorous, very direct, practical fashion acquaintance with the major problems of mental health, and mental disease and deficiency. The writers have attempted not only to outline the primarily medical and psychiatric features of these problems of mental health, but also to show their even more fundamental relations to education, and to give some realization of the frequency with which matters involving mental abnormality appear in the affairs of everyday business and professional life. The writers have, in the second place, attempted a treatment which should be of definite practical value to those interested in various special fields of work in which problems of personality and adjustment are frequently met; they have had in mind particularly social service, personnel management, work with delinquents, and those most important functionings of the school and college which involve the student's emotional and characterological development and his educational, vocational, and recreational guidance.
