What is Thomistic Philosophy?
Thomistic Philosophy refers to the philosophical methods and principles used or inspired by Saint Thomas Aquinas (1224/5-1274), a Dominican Friar and Theologian, in his explanation of the Catholic faith. Aquinas, is most renowned for his Five Ways of Proving the Existence of God (despite providing other proofs), and therefore believed that both faith and reason discover truth, a conflict between them being impossible since they both originate in God.
Believing that reason, unaided and independent of religious faith, can, in principle, lead the mind to know the existence of God and something of his nature, Aquinas defended the use of philosophy, especially in the works of Aristotle, as legitimate and beneficial within Catholic theology.

In the 13th century in which he lived, this was quite controversial, and the fact that it may not seem so today is a testament to the ultimately positive impact that he had on the Christian Church, and on the wider intellectual world as a whole. This defense of philosophy led him to incorporate philosophical insights beyond those pertaining directly to God, and so what can legitimately be termed the philosophy of Aquinas continues to offer insights into many lingering problems in Metaphysics, the Philosophy of Mind, the Philosophy of Religion, Ethics and Politics.
