A psychiatrist, at present at the Yale Institute of Human Relations engaged in research (particularly in the field of juvenile delinquency, cf. Roots Of Crime) writes on the evolution of personality, unhampered by any rigid set of rules or dogmas. From prenatal and earliest infancy through childhood and the influence of environment, he deals with the way in which personality may be affected and he relates psychiatry to social and humane problems. Illustrated with actual case histories, some normal, some abnormal. Liberal, sound and unbiased -- good foundation book for the intelligent average reader.
