What do speakers mean? What do they convey? What do they reveal? How do they invite us to think? Communication exploits conventional rules, deliberate choices, and many other faculties. How? A common answer invokes simple meanings and general ways to reinterpret them, as in H. P. Grice's theory of conversational implicature. Lepore and Stone show such answers are unsatisfactory. Instead, they argue that language provides diverse tools for making ideas public, and that communication recruits distinct kinds of imagination. The work synthesizes results from across cognitive science into a profoundly new account of meaning in language.
