 Carnap explicitly takes up the “self-undercutting” charge against verifiability in Philosophy and Logical Syntax (1935), and he is not interested in introducing a new technical term, ‘meaning’, or in denying this new technical property to unverifiable sentences. Carnap is careful to distinguish the language for which the verifiability principle is given from the meta-language in which we talk about that language. This meta-language would be the language in which the principle would be expressed. This may seem to offer another strategy against the “self-undercutting” charge because the principle applies to a different language than that in which it is expressed. This is not Carnap’s strategy. Carnap fully understands that if the general verificationist strategy is followed, there will also be a verificationist principle expressed in the meta-meta-language governing the meta-language.
