The approach to crime from the medical point of view has fascinated many a physician and general reader. The author of this book has taught his subject for some years at Bucknell University, Lewisburg, Pa. He supplements his text with case reports that are as fascinating as modern novels. His chapters concern such aspects of the subjects as the motivation of crime, psychopathy and crime, juvenile delinquency and life in prison. Dr. Lindner is convinced that there is need for far more study of the individual criminal by the methods of modern psychology and psychiatry than has thus far been applied. His approach to crime from the psychologic and sociologic points of view and what he has learned from this approach offer opportunity for application by the responsible authorities.
