Although the Jesuit Francisco Suarez (1548-1617) is one of the most important figures of late scholasticism, his work has not received the attention it deserves in English-speaking scholarly literature. One exception to this generalization is found in the work of the American scholar John P. Doyle, whose ground-breaking studies of several important areas of Suarez's complex but highly original system of thought have helped to make the Jesuit's ideas accessible to several generations of historians of philosophy. This volume gathers together Doyle's most important articles on the philosophical theology, metaphysics, ethics, and legal philosophy of Suarez, and is prefaced by an introductory chapter that places the Jesuit's life and thought in context.
