 We will return to the issue of the primary bearers of truth in section 6.1. For the moment, it will be useful to simply follow Tarski’s lead. But it should be stressed that for this discussion, sentences are fully interpreted sentences, having meanings. We will also assume that the sentences in question do not change their content across occasions of use, i.e., that they display no context-dependence. We are taking sentences to be what Quine (1960) calls ‘eternal sentences’.
