In A Companion to Giles of Rome, Charles Briggs, Peter Eardley, and seven other leading specialists provide the first synoptic treatment of the thought, works, life, and legacy of Giles of Rome (c. 1243/7–1316), one of medieval Europe’s most important and influential scholastic philosophers and theologians. The Giles that emerges from this volume was a subtle and independent thinker, who more than refining and modifying the positions of his teacher Aquinas, also made strikingly original contributions to theology, physics, metaphysics, psychology, ethics, logic, rhetoric, and political thought. He was also the founding intellectual of the Augustinian friars and a key participant in controversies at the University of Paris, and between Church and State. Contributors are: Charles F. Briggs, Richard Cross, Silvia Donati, Peter S. Eardley, Roberto Lambertini, Costantino Marmo, Martin Pickavé, Giorgio Pini, and Cecilia Trifogli.
