In this intensely interesting and original book, a distinguished administrator and scientist tells the 'plain man', in plain language, exactly what the historical and biological sciences have to say on the origin, development and prevention of War. His pacifism is based, not on sentimentality, but on the facts of human nature and human environment. For every argument f the war-mongers he has a stinging reply and against every doubt of the peace-lover a constructive and well founded encouragement. Contents Include: Pacifism The Origin and Development of War the Causes of Modern War Conditions of World Peace
