 The question as it concerns the first objection has already been answered. The supposed threat to public language arose entirely from the claim that memory-scepticism could not be confined to the private case. But since scepticism concerning memory is no part of the argument, there is no reason to suppose that any question of such confinement arises, and thus there is no question of the argument’s being self-defeating by excluding the possibility of something we know to be actual, i.e., the language we already have. Now showing the absence of any appeal to memory-scepticism involved transferring the burden of the argument from the question of whether or not an ostensive definition could be remembered or not to the question of whether there could be an ostensive definition in the first place.
