 Robert Kilwardby (ca. 1215–1279) was a Dominican Provincial and later Archbishop of Canterbury, who started his academic career around 1231 at the University of Paris. As a Master of Arts he is one of the first to comment on the newly available Aristotelian logical works, commentaries whose influence is generally recognized. His is also a widely read introduction to the sciences, the De ortu scientiarum. He is however mostly associated with Augustinian thought, especially on the plurality of substantial forms and the active nature of perception, and through his involvement in the controversy surrounding the Prohibitions in 1277 of thirty articles on logic, grammar, and natural philosophy. He was promoted to Cardinal and died soon after arriving at the Papal Court of Viterbo, in 1279.
