Saint Thomas Aquinas (c. 1225 – 7 March 1274) was a philosopher and theologian. He is best known for writing the Summa Theologiae.

"Unbelievers are in ignorance of things that are of faith, for neither do they see or know them in themselves, nor do they know them to be credible. The faithful, on the other hand, know them, not as by demonstration, but by the light of faith which makes them see that they ought to believe them, as stated above."

— Summa Theologiae II-II, Q. 1, Art. 5, reply obj. 1


Aquinas offered five proofs of the existence of God (originally called the quinque viæ):

  1. The unmoved mover
  2. The cosmological argument
  3. The argument from contingency
  4. The argument from degree
  5. The teleological argument

He proposed natural law as the foundation of morality and a variant of sensus divinitatis. [1]
