Abstract

This paper discusses the existence of rules and criteria independent of our discursive practices by using Brandom’s philosophy and Wittgenstein’s philosophical development. For that, it examines the normativity of logic, especially facing the challenge of the diversity of non-classical logics and motivates that its constitution should be based on an analogy with games. This renders a pragmatist alternative to a realist sort of dogmatism. I then defend, using this pragmatist approach inspired in the notion of games and agreements, that it is not the objectivity of discourse that makes possible the normativity of our practices, but on the contrary, it is the intrinsic normativity of our practices, its set of authorizations and prohibitions, that should ground the rationality of our discourse.
