Twentieth Century Psychology. Edited by Philip Lawrence Harri-man. [New York:  The Psychological Library. Pp.  xiii + 712. $6.]

This volume contains thirty-nine selected essays covering all fields of modern psychology. It is separated into the following eight sections: General and Theoretical, Social Psychology, Animal Psychology, Experimental Psychology, Psychology of Aesthetic Experience, Abnormal Psychology, Differential Psychology, and Child Psychology.

In such a review as this, it is impossible to discuss the individual articles, but it should be emphasized that they are all well-written and are sufficiently diversified to make an appeal to the interest of any reader. The studies vary from those on Nazi science to problems in ant learning, discussions of the American caste system and the question of Negro intelligence. Among the more interesting from a casual point of view are the study by Hartman dealing with the Black Hole of Calcutta and the study by Starch on the world's 100 greatest books. Psychiatrists will find the article, “Toward a Practical Concept of Neurosis,” by Dunlap provocative and worthy of consideration even though they may disagree with many of his concepts. The discussions on hypnotic technique by Brenman and Gill are particularly good. The section on differential psychology and the general theoretical articles should prove intriguing to any intelligent reader.

This idea of appealing to the general reader who desires to become acquainted with the work of psychology is stressed by the editor, and he has certainly achieved his aim. The book is an excellent sampling of current psychological work. It should prove of value not only to students of psychology but to all individuals concerned in any way with psychological investigations or problems of human relationships.

Because of its diversity of topics, it is not a book to be read through at one sitting but rather should be readily available in the library for dipping into at frequent intervals for both intellectual pleasure and profit.
