 Many have construed Kripke’s Wittgenstein as saying exactly that: it is part of his skeptical campaign against semantic facts in general that such facts cannot be reduced to whatever precisely is allowed in a naturalistic supervenience base for meaning/content. An argument for this could take a weaker, intensionalist, and a stronger, extensionalist, form (cf. Boghossian 1989a: 532ff). The stronger argument concludes that no reductive naturalist account of meaning/content will be extensionally correct: For any meaning/concept, such an account will either include objects in its extension that, intuitively, do not belong there, or exclude objects from its extension that, intuitively, do belong there, or both. As we saw above  (section 2.2.1),  this “problem of error” is a problem for many naturalistic accounts of meaning/content, but as such it does not yet have anything to do with normativity. To that, the normativist could respond that it is precisely because of their essential normativity that no naturalistic account of meaning/content can be extensionally correct. The weaker argument grants extensional correctness, but argues that no naturalistic reduction will get the intension of the notion of meaning/content right; it will inevitably miss the normative character of what is semantically correct, its deontic or axiologic characteristics.
