Abstract

Every educated person in the Middle Ages learned logic, which was then always some version of the theory of the syllogism. But until the rise of the universities in the thirteenth century no scholar in Christendom had written a comprehensive commentary on the work of Aristotle's that contains that theory, namely the Prior Analytics. Robert Kilwardby was an English scholar who lectured on logic and grammar at the University of Paris in the 1230s. His lectures earned him widespread fame in Europe. Throughout the thirteenth century and up to the sixteenth,Kilwardby's lectures on Aristotle's Prior Analytics were considered to contain the authoritative exposition of Aristotle's syllogistic logic. They were published at Venice in 1499.
