This collection of essays revisits Jacques Maritain's book, Man and the State - the University of Chicago Walgreen lectures of 1949 - and critically engages its greatest themes and arguments: the character of the modern state and its relation to the body politic, the state's functions and claims, the basis of authority, the foundation of human rights and natural law, structural pluralism, Church and State relations, national sovereignty, and the prospects for world government. The contributors address whether Maritain has successfully accomplished his project of engaging modernity from the perspective of a 20th century disciple of Thomas Aquinas; whether his reformulations and revisions of the modern state are philosophically sound and prudent; and whether his developments of Aristotle and Aquinas are faithful to the sources. Maritain, drawing upon the philosophy of Aquinas, represents a significant achievement: he provides a viable reassessment of the liberal state, uniting Thomistic and Aristotelian traditions with the human rights thrust of modern political philosophy. The contributors to this collection find Maritain has achieved much in the accomplishment of this project. Some continue this project by applying Maritain's philosophy to contemporary issues. Other contributors find it helpful, however, to compare Maritain to other contemporary political philosophers, and to question his use of the philosophy of Aquinas. Maritain's political philosophy, and Man and the State in particular, is worth continued study. His work shows a remarkable resilience and relevance to the issues of the day, offering a deeper philosophical foundation and more flexible set of tools for analysis than currently provided.
