 The other formulation of the problem is this (Kripke p. 62): “Wittgenstein questions the nexus between past ‘intention’ or ‘meanings’ and present practice: for example, between my past ‘intentions’ with regard to ‘plus’ and my present computation … .” The idea is that my grasp of the rule governing the use of ‘plus’ does not determine that I shall produce a unique answer for each of indefinitely many new additions in the future. The impression that something is missing here, though, is a result of just that kind of confusion about determination identified in the section headed ‘The Significance of the Issue’ above.
