Thomas Aquinas (1225-1274 AD)

Italy

Thomas Aquinas was born the seventh son of an Italian nobleman. His family wanted him to join a group of monks called the Benedictines, but he wanted to be a Dominican monk instead. When he ran away to join the Dominicans, his brothers kidnapped him and brought him back. His family finally allowed him to join the Dominicans. As part of the Dominicans, Aquinas had the opportunity to study ancient Greek philosophers, such as Plato and Aristotle. His goal became proving God’s existence through reason, the tool of philosophy.

Before Thomas Aquinas, people believed that faith in God was in conflict with philosophy. Aquinas, a monk, set out to change that belief. He believed that Aristotle’s "unmoved mover," a supreme being whose existence at the beginning of time set the universe in motion, was the same as the Christians’ God, who created all things. He believed that without God there was no universe because "to take away the cause is to take away the effect." Aquinas provided five proofs that show the existence of God in his book Summa Contra Gentiles. Aquinas also believed that all living things had souls, and that people's souls had the ability to reason.
