Duns Scotus

Life

Duns Scotus was born in 1266 in Duns, Scotland. He joined the Franciscan Order and studied at Oxford and Cambridge before being ordained in 1291. He taught at Oxford and then at the University of Paris, where he became a regent master in 1305. In 1307, he was transferred to the Franciscan studium in Cologne, where he died on November 8, 1308, at the age of only 42.

Despite his short life, Scotus produced a vast body of extraordinarily dense and technical philosophical work. His early death left many works incomplete, and the textual tradition is complex — separating genuine works from later additions has been a major project of modern scholarship.

The Univocity of Being

Scotus' most important metaphysical thesis is that the concept of 'being' (ens) is univocal — it applies in the same basic sense to everything that exists, including God and creatures. This directly opposes Thomas Aquinas' doctrine of the analogy of being, which holds that 'being' is predicated of God and creatures in an analogical sense. Scotus argued that unless we have a univocal concept of being, no reasoning from creatures to God is possible — we could not even begin to think about God.

Haecceity

Scotus introduced the concept of haecceitas ('thisness') — the principle of individuation that makes each individual thing the unique individual it is. For Scotus, what makes Socrates Socrates is not his matter (Aquinas' view) or his collection of universal properties, but an irreducible individual difference — his haecceity. This idea has been enormously influential in the history of philosophy, from medieval debates to modern discussions of individuality and identity.

Voluntarism

Scotus emphasized the primacy of will over intellect in both God and human beings. God's will is genuinely free — God chose to create this world from among genuinely possible alternatives, not because this world is the 'best possible' (as Leibniz would later argue). In human beings, the will has a genuine power of self-determination that cannot be reduced to the dictates of reason. This voluntarism influenced the entire tradition of Western thinking about freedom.

Legacy

Scotus was beatified in 1993. His philosophical influence was immense — 'Scotism' was a major school of thought rivaling Thomism throughout the late medieval and early modern periods. His ideas about univocity, haecceity, and the primacy of will influenced Ockham, Suárez, Leibniz, Peirce, Heidegger, and Deleuze.
