"Much of the philosophical work of the last half-century could not have existed without Naming and Necessity. If you read this marvelous book, you???ll find out why." David Chalmers, University Professor of Philosophy and Neural Science and co-director of the Center for Mind, Brain, and Consciousness, NYU "Naming and Necessity represents a turning-point in the development of modern philosophy. It showed how confusions in the philosophy of language had blocked progress in metaphysics, and it provided a model of systematic philosophical theorizing informed by innovations in logic." Timothy Williamson, Wykeham Professor of Logic Emeritus, Oxford University Since first appearing in 1972, Saul Kripke's Naming and Necessity has shaped and continues to shape debates in metaphysics, the philosophy of language, and adjacent areas. It overturned long-established views concerning the relationships between names and descriptions and a priority and necessity, and catalyzed today's thriving essentialist metaphysics. This landmark work is here reissued for its 50th anniversary with a new preface by the author revisiting its central themes. If there is such a thing as essential reading in analytic philosophy, this is it.
