O que faz uma regra?: desenvolvimentos de uma imagem wittgensteiniana do significado

Abstract

This dissertation consists in an exposition and examination of some attempts to explain and develop Wittgensteins observations on the normative relation between the speakers understanding and their courses of action a relation summarized by the concept of linguistic rule. Its the effort to map some pertinent questions about these developments, such as shown by the communitarism of Saul Kripke, Michael Dummett and Crispin Wrights anti-realism, and John McDowells anti-reductivism. The four authors start from distinct points of view, which enable them to elaborate different images of the commitments constituents with witch we engage ourselves when we participate in the understanding of a language. In this way, the dissertation does not try to establish the best interpretation of Wittgensteins philosophy, but to determine an important part of his heritage to the XX centurys philosophy.
