Robert S. Hartman's life was marked by war. Hartman devoted much of his extraordinary intellectual capacity to understanding and articulating the political, philosophical, psychological, and spiritual causes of war so that humankind could stop waging war and start living together in peace. This collection of essays by Hartman reveal, for the first time in one place, the range and depth of his thoughts on this subject. It also traces how his own understanding of the role of war in human society evolved during his lifetime. It was his study of war that led, in large part, to his development of the value theory for which he is best known-formal axiology. Hartman's ideas, if understood and embraced, may well lead to fulfillment of his hope that we can learn to live in peace. This book will naturally be of interest to the historian and the political scientist. But, it offers much more than a historical record. Hartman offers lessons that will benefit any informed global citizen today. For more information on Hartman and his legacy, visit www.hartmaninstitute.org.
