The engaging and inquiring mind of French philosopher Jacques Maritain reflected on subjects as varied as art and ethics, theology and psychology, and history and metaphysics. Maritain's work on the theoretical groundings of politics arose from his diverse studies. In this book, distinguished theologian and political scientist James V. Schall explores Maritain's political philosophy, demonstrating that Maritain understood society, state, and government in the tradition of Aristotle and Aquinas, of natural law and human rights and duties. Schall pays particular attention to the ways in which evil appears in political forms, and how this evil can be morally dealt with. Schall's study will be of great importance to students and scholars of political science, philosophy, and theology.
