Two Epistemological Arguments against Two Semantic Dispositionalisms

Even though he is not very explicit about it, in Wittgenstein on Rules and Private Language Kripke discusses two different, albeit related, skeptical theses – the first one in the philosophy of mind, the second one in the metaphysics of language. Usually, what Kripke says about one thesis can be easily applied to the other one, too; however, things are not always that simple. In this paper, I discuss the case of the so-called “Normativity Argument” against semantic dispositionalism (which I take to be epistemological in nature) and argue that it is much stronger as an argument in the philosophy of mind than when it is construed as an argument in the metaphysics of language.
