<P>Saul Kripke is one of the most important philosophers of the twentieth century. His most celebrated work, <I>Naming and Necessity</I>, makes arguably the most important contribution to the philosophy of language and metaphysics in recent years. Asking fundamental questions - how do names refer to things in the world? Do objects have essential properties? What are natural kind terms and to what do they refer? - he challenges prevailing theories of language and conceptions of metaphysics, especially the descriptivist account of reference, which Kripke argues is found in Frege, Wittgenstein and Russell, and the anti-essentialist metaphysics of Quine.</P><P></P><P>In this invaluable guidebook to Kripke''s classic work, Harold Noonan introduces and assesses:</P><P></P><UL><P><LI>Kripke''s life and the background to his philosophy</LI><P></P><P><LI>the ideas and text of <I>Naming and Necessity</LI><P></P></I><P><LI>the continuing importance of Kripke''s work to the philosophy of language
