Art," "Man and the State," and "Factors in American Civilization," this volume carries evolutionary principles into the field of individual life and character, and shows their application to the practical problems of hygiene, sociology, religion and applied ethics. The writers are for the most part masters of the topics assigned them for treatment, and we confidently commend their work to thoughtful and intelligent readers who would know the last word of the evolutionist upon the most vital of all the questions of the time.
