Introduction

Sarah Byers is an assistant professor of philosophy at Boston College. She says Augustine's principal sources were Cicero and Seneca. In the city of God 14, he uses a Greek term, Yupathea, which is a technical stoic term for a morally good emotion. It seems that either he knew it from a Latin source that's not extant anymore, like part of Cicero's De Fato or else he had an anthology of extracts from Greek philosophers translated into Latin.
