Thomistic Philosophy is inspired by the philosophical methods and principles used by Thomas Aquinas (1224/5-1274), a Dominican Friar and Theologian, in his explanation of the Catholic faith. Aquinas, who is most renowned for his Five Ways of Proving the Existence of God, believed that both faith and reason discover truth, a conflict between them being impossible since they both originate in God.

Believing that reason can, in principle, lead the mind to God, Aquinas defended reason's legitimacy, especially in the works of Aristotle. The philosophy of Aquinas continues to offer insights into many lingering problems in Metaphysics, the Philosophy of Mind, Philosophy of Religion and Ethics.
