This book shall give information to practitioners and others on the subject of nervous disorders, and especially knowledge of the significant contributions of Sigmund Freud. A need for a simple, comprehensive presentation of the Freudian principles is met in this primer of psychotherapy, providing enough of biological and psychological background to make them intelligible, and enough application and illustration to make them useful to the general practitioner or the average layman. - Excerpted from summary by JFSmoyer
