This collection brings together thirty-five letters and sermons of Augustine, Bishop of Hippo from 396-430 AD, that deal with political matters. The letters and sermons are both practical and principled and treat many essential themes in Augustine's thought, including the responsibilities of citizenship, the relationship between the church and secular authority, religious coercion, and war and peace. These texts complement Augustine's classic The City of God, and give students direct insight into the political and social world of late antiquity with which Augustine was immediately involved.

The great medieval philosopher Thomas Aquinas (1224/6-1274) was Dominican regent master in theology at the University of Paris, where he presided over a series of academic debates on ethical topics. This volume offers new translations of disputed questions on the nature of virtue. The introduction explains how Aquinas' theory of virtue fits into his conception of ethics as a whole, and clarifies Aquinas's views by explaining the institutional and intellectual context in which the disputed questions were debated.
