Social Psychology.

The article discusses books and authors. The title of the book "Principles of Social Psychology" is misleading, for the nature of the contents does not nearly justify the title, either with or without the obscurely placed sub-title, "as Developed in a Study of Economic and Social Conflict." The author James M. Williams has not addressed himself to the major problems of social psychology raised by other prominent sociologists, although he has made use by application of some of the conclusions of the theories.
