Through a penetrating interview and sixteen essays, this volume explores key intersections of medieval religion and philosophy. With characteristic erudition and insight, Remi Brague focuses less on individual Christian, Jewish, and Muslim thinkers than on their relationships with one another. Their disparate philosophical worlds, Brague shows, were grounded in different models of revelation that engendered divergent interpretations of the ancient Greek sources they held in common. So, despite striking similarities in their solutions to the philosophical problems they all faced, intellectuals in each theological tradition often viewed the others' ideas with skepticism, if not disdain. Brague's portrayal of this misunderstood age brings to life not only its philosophical and theological nuances, but also its true lessons for our own time.
