A text—book of 430 pages for beginners and more advanced students in the field of psychology. The author has had broad experience as a

teacher in psychology and as a director of a clinic for mental hygiene, dealing with borderline cases and neurotic children, and much practical work in the World war as major in the Medical Corps in the United States Army, in England and France. In the text throughout the volume he cites cases to illustrate the various reactions among his patients. He deals not only with psychology but the points of contact of psychology with philosophy and this special feature should have its usefulness for spiritual advisors, physicians, psychologists and social workers.

The work is divided into six main parts and these are subdivided into chapters. In addition there are succinct conclusions and an excellent glossary which will prove very valuable especially to the beginner and the person without special training in this line of work. Part I reviews the various concepts of psychology from those of the Sophists on and discusses the relation of psychology to the other sciences. Dr. Moore's concept of the Conscious and Unconscious is not unlike Freud's; he comments: “But in the midst of all these changes, great or little, there is only one psychic field in which they occur, and that is the one Ego, the one metaphysical personality, the one substrate of our mental life.” His methods of investigating the unconscious do not deviate from the accepted methods of to—day, i.e., dreams, associations, etc. In the discussion of the classification of the mental processes he reviews the dual classification distinguishing between sensory and intellectual forms and the triple division of Kant as well as other classifications, including the scholastic one.

Part II deals with Stimulus, Response and Human Behavior. These are fully considered from their physiological and biological aspect including Reflex Action, Reaction—Time Experiments and Tropisms.

Part III takes up
