Rule-Following, Dispositionalism, and Functionalism
In “Kripke and Functionalism” (Episode 61), Buechner describes how Kripke’s criticism of the dispositionalist response to the ‘rule-following paradox,’ found in Wittgenstein’s Philosophical Investigations,can be generalized as a criticism of functionalist accounts of mental states, the thesis that mental states are abstract computational states realized in physical objects, like a brain. Here, I’d like to give a sketch of the rule-following paradox, the dispositionalist response, and Kripke’s criticism in Wittgenstein on Rules and Private Language, in order to give you a clearer idea of the criticism of functionalism Buechner points to. (For those following along at home, the crux of the rule-following paradox can be found in §§185-202 of the Investigations; Kripke’s (articulation of what he takes to be Wittgenstein’s) criticism of the dispositionalist response can be found on pages 22-35 of Wittgenstein on Rules and Private Language.) ...
