Yves Simon was one of the preeminent Thomistic philosophers and political theorists of the twentieth century. He saw it as a moral duty to understand human reality and to use philosophical analysis to examine contemporary politics when they embodied philosophical errors or vicious ideologies. In "The Ethiopian Campaign and French Political Thought", Simon extracts principles from the 1894 Dreyfus Affair in France and applies them to Italy's 1935 invasion of Ethopia. As Simon's analysis shows, the relatively obscure events leading up to the Italian invasion had larger implications for Europe and the world, perhaps even paving the way for Vichy France's collaboration with Hitler's German New Order. This book, available for the first time in English, offers an interesting case study of such ethical concerns as just war theory and preemptive war, and is of particular relevance in our modern political climate.
