The Summa Theologica (Summary of Theology) was written by Thomas Aquinas from 1265-1274. It is considered his best-known work. The Summa is one of the most influential works of Western literature, and it’s well known for its five arguments for the existence of God, which are known as the “five ways” (Latin: quinque viae). It provides a synthesis of Christian thought and has impacted philosophy and religion since it was written.
