Publisher's Synopsis
A contemporary of John Duns Scotus and William of Ockham, Burley was active at the universities of both Paris and Oxford. He became one of the most important figures in the transformation of medieval logic and semantics that took place in the early fourteenth century. Burley used new tools and techniques of logical and semantical analysis, yet in many cases he used them in defense of traditional views, such as a realist metaphysical theory of "universals." On the Purity of the Art of Logic shows both these sides of Burley-the innovator and the conservative-as well as some of the ways in which his views corresponded or clashed with those of William of Ockham.
