Most readings of the meaning skepticism Kripke ascribes to Wittgenstein understand it as metaphysical. The threat to meaning is supposed to follow immediately from the impossibility of citing facts in which meaning consists. I offer an alternative, epistemological, reading that is closer to Wittgenstein. What threatens meaning is the worry that, when I use an expression on any given occasion, I cannot know that my use conforms to previous uses of the expression; instead, in Wittgenstein’s terms, I go on “blindly,” without the understanding which is necessary for meaningful use. This reading makes for a stronger skeptical argument, in that it blocks the non-reductionist response of taking meaning facts to be primitive. But the argument, on this reading, can still be answered: not by citing meaning facts but by showing that I can know how to go on with an expression without needing to appeal to what the expression means.
