The most comprehensive collection of its kind, this unique anthology presents fifty-four readings--many of them not widely available--by the most important and influential Christian, Jewish, and Muslim philosophers of the Middle Ages. The text is organized topically, making it easily accessible to students, and the large selection of readings provides instructors with maximum flexibility in choosing course material. Each thematic section is comprised of six chronologically arranged readings. This organization focuses on the major philosophical issues and allows a smooth introduction to the material. The topics covered are: (1) The Existence of God, (2) Ethics and the Problem of Evil, (3) God's Foreknowledge and Free Will, (4) Theology, (5) Political Philosophy, (6) Knowledge and Sensation, (7) Universals, (8) Logic and the Philosophy of Language and (9) Physics. Each text is preceded by a biographical note on the author and a brief analytical introduction. Unlike other anthologies, which present sources as a series of truncated excerpts, this collection avoids intrusive editing and includes many selections in their entirety, thus preserving the rich flavor of the medieval mind at work.
