1215 – 1279
Robert Kilwardby (c. 1215–1279) was an English Dominican friar, logician, and Archbishop of Canterbury whose scholastic work synthesized Augustinian theology with Aristotelian natural philosophy and logic. He composed the encyclopedic De ortu scientiarum, a systematic classification of the sciences, and wrote extensive commentaries on Aristotle's Organon and Priscian's grammar. As Archbishop, he issued the Oxford Condemnation of 1277, censuring thirty philosophical propositions in opposition to emergent Thomistic positions.
