PSYCHOLOGY AND SOCIAL SANITY.
Psychology and Social Sanity. By Hugo hifinsterberg. (T. Fisher Unwin. 5s. net.)—Since Professor Miinsterberg made his reputation as a critic of national life with The Americans, be has from time to time emerged from his psychological laboratory at Harvard to throw light on some of the problems of the day. He holds this to be part of his professional duties. "Our practical life is filled with psycho- logical problems which have to be solved somehow, and if everything is left to common-sense and to unscientific fancies about the mind confusion will result, and the psychologist who stands aloof will be blamed." In the present collection of essays he deals with such subjects as sex education, the mind of the juryman, efficiency on the farm, the ethics of advertising, and thought transference. All that he says is well worth reading.
