 They claim that it is not difficult to understand what someone would mean by uttering (1), and it is fairly clear what it would take to persuade someone that (1) is not false, as seems initially evident. But in the case of (2), they argue, in effect, that with further investigation one would either conclude that the speaker was using familiar words to express new concepts, or else would conclude that nothing at all was being said. No attempt will be made here to adjudicate the dispute with Quine, who would reject both of these dichotomies (new concepts/old concepts, something said/nothing said) as well. But the reader should note that the crucial claims are that someone who asserts (2) is either asserting it with a meaning other than the standard conventional one, or with no meaning at all. A further elaboration of their claims depends therefore on elucidating the notion of the meaning of an utterance, and Section 4 will explore Grice’s account of this notion further.
