 Suppose I do mean addition by ‘+’. What is the relation of this supposition to the question how I will respond to the problem ‘\(68+57\)’? The dispositionalist gives a descriptive account of this relation: if ‘+’ meant addition, then I will answer ‘125’. But this is not the proper account of the relation, which is normative, not descriptive. The point is not that, if I meant addition by ‘+’, I will answer ‘125’, but that, if I intend to accord with my past meaning of ‘+’, I should answer ‘125’. Computational error, finiteness of my capacity, and other disturbing factors may lead me not to be disposed to respond as I should, but if so, I have not acted in accordance with my intentions. The relation of meaning and intention to future action is normative, not descriptive. (Kripke 1982: 37)
