Thomas Aquinas (c. 1224-74) was born in Aquino, southern Italy, was educated at the Benedictine Abbey of Monte Cassino and became a priest of the Dominican Order. He studied at the universities in both Paris and Naples and taught at the universities in Orvieto and Rome. Aquinas was a follower of Scholasticism, in which Aristotelian logic is applied to philosophical and theological questions. One of his greatest works was the Summa Theologiae, which he intended to be an introductory text for the university student. The Summa Theologiae presents a series of questions, objections, and resolutions concerning theology, the existence of God, and the nature of the soul. See Philosophy and Theology for more of an introduction to the topic.
