  As we have just seen, even sentences which we cannot imagine rejecting might, in principle, be rejected. As Quine says: ‘no statement is immune to revision’ (1951, 43; see Ebbs 2017, Ch. 8). This claim of Quine’s has attracted a good deal of attention, and is sometimes thought to be shocking or even paradoxical. In the context of his debate with Carnap, however, it is not, by itself, at all surprising. For Carnap too, any sentence can be revised; he would insist, however, that in the case of some sentences, the analytic ones, a revision involves a change of language, and thus of the meaning of the words used in the sentence. So the idea of meaning, and sameness of meaning, occupies a crucial role in the debate over analyticity.
