Foundations of Speech Act Theory investigates the importance of speech act theory to the problem of meaning in linguistics and philosophy. The papers in this volume, written by respected philosophers and linguists, significantly advance standards of debate in this area. Beginning with a detailed introduction to the individual contributors, this collection demonstrates the relevance of speech acts to semantic theory. It includes essays unified by the assumption that current pragmatic theories are not well equipped to analyse speech acts satisfactorily, and concludes with five studies which assess the relevance of speech act theory to the understanding of philosophical problems outside the area of philosophy of language.
