This book is a true classic, both in content and in its formulation. Quine's style, expressive and elegantly precise sometimes ironic, is unique in the literature of analytic philosophy, but Word and Object is not an easy book: it is recommended to address some training in philosophy, logic and linguistics, as well as logical positivism against which Quine reacted. In return for its difficulty, this book contains the famous second chapter (the thesis about the indeterminacy of translation and the notion of radical translation), a fascinating linguistic reformulation of the problem of "other minds" may seem a cliché, but takes Quine to treat a large number of epistemological, logical and metaphysical. Quine's conclusions in these areas were so unusual and still deep (more than four decades after the first edition of Word and Object) are studied philosophy. Quine Was he right? Surely not, but like all great philosophers, brought a new perspective on old issues, and opened our eyes to problems never knew existed. Word and Object, with Philosophical Investigations, Wittgenstein, The Concept of Mind, Ryle, and Empiricism of Mind, stamps, complete tetralogy of analytic philosophy in the second half of the twentieth century.
