Aristotle's theory of truth spans several areas of philosophy: philosophy of language, logic, ontology, and epistemology. Paolo Crivelli covers the main aspects of Aristotle's views on truth and falsehood in this volume by analyzing in detail the relevant passages and addressing well-known problems of Aristotelian semantics. Although Crivelli assesses Aristotle's theory from the point of view of modern analytic philosophy, his book will be of interest to a wide range of students of ancient philosophy and modern philosophy of language as well.
