This book was the winner of the Prize Contest of 1943 for the best religious manuscript by a new writer. It is safe to predict that the Protestant Christian world will hear much of this brilliant young Professor of Christian Ethics in the years to come, and have many more volumes from his facile pen. Professor Ropper gives us a philosophy of history as well as a history of philosophy. He outlines for us the cultural and intellectual trends which have brought the world to this crisis and gives an interpretation of our religious heritage which he believes alone can carry us through these critical years. There is brilliant scholarship behind the book, and lucid writing in it. Students of history, clergymen, philosophers and all interested in an intelligent and Christian appraisal of our world would profit by its reading.
