The document discusses St. Thomas Aquinas. As a child, Aquinas was sent to a monastery at age 5 and was later imprisoned by his own family for nearly 2 years. He wrote influential works including Summa Theologica and Summa Contra Gentiles. Aquinas' philosophy holds that physical objects and the mind are created by God, and faith and reason can know God. His teachings form the basis of Catholic philosophy and he advocated that reason and faith are complementary.
