Thomas Aquinas becomes one of the most influential thinkers in Medieval Europe when he reconciles Christian theology with ancient Greek philosophy. For instance, he uses principles from Aristotle to prove the existence of God.


In 1277, many of Aquinas’ propositions are condemned and banned by the Bishop of Paris.


Reason in man is rather like God in the world.
– Thomas Aquinas, Opuscule II, De Regno
