 As we’ll see, the search for a fact fails, and the sceptic concludes that “the entire idea of meaning vanishes into thin air” (Kripke 1982: 22). Kripke rejects this paradoxical conclusion as “insane and intolerable” (1982: 60) and “incredible and self-defeating” (1982: 71), and goes on to develop, on behalf of Wittgenstein, a sceptical solution, which he takes to be similar in some respects to David Hume’s solution to the sceptical problem about causation (1982: 4; 62–69), and which purports to conceive of meaning in a way that does not lead to paradox. We discuss the sceptical solution in  section 3.  (George Wilson was the first to insist on the significance of the distinction between the parts of the sceptic’s position Kripke’s Wittgenstein accepts and the parts he rejects—between the basic sceptical conclusion, according to which there are no facts about a speaker of the sort that the sceptic is seeking that constitute her meaning something by an expression, and the radical sceptical conclusion, according to which no one means anything by an expression [Wilson 1994, 1998]. We will return to Wilson’s view in  section 3.3.)
