Duns Scotus

<p>John Duns Scotus was born around March 1266 in Duns, Berwickshire, Scotland. Entering the Order of Friars Minor (Franciscans) around 1279, he was ordained a priest at Northampton in March 1291. He studied and lectured at the University of Oxford and Cambridge before being summoned to the prestigious University of Paris (Sorbonne) in 1302.</p><p>In 1303, when King Philip IV of France attempted to depose Pope Boniface VIII, Scotus courageously refused to sign the king's anti-papal petition, facing immediate expulsion and exile from France rather than compromising his conscience. Returning to Paris after reconciliation, he was promoted to Regent Master of Theology in 1305.</p><p>Scotus earned the immortal scholastic title <strong>Doctor Subtilis</strong> ('The Subtle Doctor') for his razor-sharp analytical distinctions and nuanced metaphysics. His two most transformative philosophical breakthroughs were the <strong>Univocity of Being</strong> (the doctrine that 'being' is predicated univocally of both God and creatures, unifying metaphysics) and <strong>Haecceity</strong> (from the Latin <em>haecceitas</em>, or 'thisness'—the discrete, irreducible principle that makes an individual thing this unique individual rather than merely a member of a species). He also formulated the theological argument for the Immaculate Conception of Mary that the Catholic Church officially defined centuries later. In 1307, Scotus was assigned to Cologne, where he died unexpectedly on November 8, 1308, at age forty-two. He was beatified by Pope John Paul II in 1993, who hailed him as a 'cantor of the Incarnate Word and defender of the Immaculate Conception.'</p>
