A Confirmation Criterion of Synonymy
Two declarative sentences are synonymous if, and only if, the statements they can be used to make are. given certain assumptions about the truth or falsity of other statements, confirmed or disconfirmed to the same degree by the same evidence. This criterion of synonymy is Quinean in that it treats confirmation holistically. But unlike Quine's criterion of synonymy, it conforms to and explains our intuitions of sentence synonymy.
