Saint Thomas Aquinas (1225–74) was a medieval Italian philosopher, theologian, and Dominican friar. He is recognized as the leading theological authority within the Roman Catholic Church—his philosophies regarding human rights and natural law, derived from Aristotelianism, prevail at the heart of the Catholic canon even today.
Aquinas is regarded as the most significant medieval figure of scholasticism. He reconciled the faith of Christian theology with Aristotelian reason. His incomplete Summa Theologica (1266–73) made intellectual arguments for the existence of God based on reason and observation—Aquinas’s “five proofs” are generally seen as genuine arguments for the reality of God.
Aquinas wrote some 60 works; in addition to his theological writings, Aquinas wrote such philosophical works as On Being and Essence (De ente et essentia, ad fratres socios, 1252–56,) On the Principles of Nature (De principiis naturae ad fratrem Sylvestrum, c.1255,) and Disputed Questions on Truth (Quaestiones disputatae de Veritate, 1256–59.) Aquinas’s many commentaries on Aristotle introduced Aristotelianism to Christian Western Europe.
Aquinas died on a journey to a church council in Lyons after being knocked from his donkey when it scurried under a low tree limb. According to legend, the donkey died of regret.
Aquinas was canonized in 1323; his feast day is January 28.
