Abstract

William of Ockham is a towering figure in the history of philosophy and he is commonly seen as the most important nominalist thinker of the Middle Ages. His nominalism basically consists in three theses: there are no universals in the external world, no relations either, and no quantities considered as distinct entities. This book provides an introduction to Ockham's defence of these positions and to what they amount to in metaphysics, semantics, and epistemology. It thus displays the outlines of a rich and carefully crafted nominalist system that is still of great philosophical interest today. All along in so doing, it situates Ockham's thought with respect to several salient contemporary debates in philosophy.
