"This superb book takes on some of the hardest and longest-standing problems in the philosophy of language, including Frege's identity puzzle and Kripke's 'Paderewski' puzzle. It offers elegant solutions to these problems in the form of applications of an insightful theory of the nature of beliefs about language. The authors bring to this theory an impressive combination of technical sophistication and philosophical subtlety."
