Although best known for his views about universals and his dramatic love affair with Heloise, Peter Abelard (1079-1142) also made important contributions in metaphysics, logic, philosophy of language, mind and cognition, philosophical theology, ethics, and literature. The essays in this volume survey the complete range of Abelard's thought by examining his overall achievement in its intellectual and historical context. They also trace Abelard's influence on later thought and his relevance to contemporary philosophical debate.
