Duns Scotus lectures in Oxford
1299
The Scottish Franciscan philosopher John Duns Scotus began his Oxford lectures on Peter Lombard's Sentences, developing a subtle metaphysics of individuation and divine will that would earn him the nickname the Subtle Doctor and a permanent place alongside Aquinas in Catholic theology. His concept of haecceity, the thisness that makes each individual unique, anticipated modern debates about personal identity and the nature of particulars.
