This book provides a clear and comprehensive introduction to the work of Willard van Orman Quine, one of the most notable American philosophers of the post-war period. An understanding of Quine's work should assist anyone who wishes to follow contemporary debates in the philosophy of language, the philosophy of mind and metaphysics. The author traces the development of Quine's work from his early criticisms of logical positivism and empiricism to his more recent theories about mind and meaning. He gives particular attention to Quine's controversial arguments concerning the indeterminacy of translation, comparing Quine's views with those of Davidson, Putnam and others. Hookway concludes by offering a critical appraisal of Quine's approach and of some of his fundamental philosophical commitments.
