Quintessence for the first time collects Quine's classic essays (such as "Two Dogmas" and "On What There Is") in one volume - and thus offers readers a much-needed introduction to his general philosophy. Divided into five parts, the twenty-five selections take up analyticity and reductionism; the indeterminacy of translation of theoretical sentences and the inscrutability of reference; ontology; naturalized epistemology; philosophy of mind; and extensionalism. Representative of Quine at his best, these readings are fundamental not only to an appreciation of the philosopher and his work, but also to an understanding of the philosophical tradition that he so materially advanced.
