Bl. John Duns Scotus
c. 1266–1308 · Scotism
Beatified 1993 by St. John Paul II; Doctor Subtilis, Doctor Marianus.
Franciscan master at Oxford and Paris, Scotus argued for the univocity of the concept of being, the formal distinction, individuation by “haecceity,” and the primacy of the will over the intellect in beatitude. He gave the decisive argument for the Immaculate Conception (Mary preserved from sin by a more perfect redemption) and held that the Incarnation was willed by God before and apart from the Fall.
Why he matters: His Marian theology became dogma in 1854, and Scotism stood beside Thomism for centuries as a legitimate Catholic school; his voluntarism, moderated and orthodox, is the hinge between the high scholastics and the nominalists.
Where to be careful
Univocity of being and the stress on the divine will were pushed by later thinkers (Ockham) into errors Scotus himself did not hold; his subtlety repays, but demands, careful reading.
