A brilliant and penetrating study of three men on three fronts, the scientist, the sociologist, the artist, each one of whom established certain traditions by which we live. On the eve of new acceptances of new scientific theories he sees fit to appraise the contribution they have made. The book is biography, criticism, history philosophy. He surveys the inherited tradition for each man in his own field; he traces the impact of the new thought on the contemporary scene. Through these pages the social revolution, the scientific revolution and the artistic revolution take on new meaning, the three blending, overlapping, playing off against each other, and emerging as a unity of common thought, common approach, common line of development. Not a book for light reading, but a serious scholarly study.
