John Duns Scotus

Blessed John Duns Scotus (c. 1266 – November 8, 1308) was a theologian, philosopher, and logician. He is considered one of the most important Franciscan theologians and was the founder of Scotism, a special form of Scholasticism. Some argue that during his tenure at Oxford, the systematic examination of what differentiates theology from philosophy and science began in earnest. He was known as Doctor Subtilis due to his subtle merging of differing views. Later philosophers were not so complimentary about his work, and the modern word dunce comes from the name "Dunse" given to his followers.
