Meaning Scepticism, Factualism and Anti-realism

In this paper I take up my discussion with Perez Otero concerning how to understand Wittgenstein. I defend the thesis that Wittgenstein's grammatical analysis implies that attributions of understanding and rule-following have a retrospective character, in line with the analysis of the grammar of "capacity", which attributes "states" to objects on the basis to their effects. I point out that this thesis does not led to an incoherent anti-realistic position, because it is an integral part of the deflationary factualism that we find in the "sceptical solution" proposed by Kripke in his interpretation of Wittgenstein's rule-following considerations. In contrast, I point out the inconsistency of positions that attempt to limit their anti-realistic moment to the critique of subjectivist mentalist truth conditions. I analyze the difficulties of this conception in the elucidation of the concept of criterion, showing how a sceptical elucidation of this concept avoids these difficulties.
