Quine was one of the foremost philosophers of the Twentieth century. In this outstanding overview of Quine's philosophy, Peter Hylton shows why Quine is so important and how his philosophical naturalism has been so influential within analytic philosophy. Beginning with an overview of Quine's philosophical background in logic and mathematics and the role of Rudolf Carnap's influence on Quine's thought, he goes on to discuss Quine's famous analytic-synthetic distinction and his arguments concerning the nature of the a priori. He also discusses Quine's philosophy of language and epistemology, his celebrated theory of the indeterminacy of translation and his broader views of ontology and modality. This book is essential reading for anyone interested in Quine, twentieth century philosophy and the philosophy of language.
