Normatividade e Determinação nas Investigações Filosóficas

Abstract

A great deal of Wittgenstein’s efforts in his major work, the Philosophical Investigations, is oriented against the idea that the normativity of logic is a compelling force over the speakers of a language. According to this conception, the logic and its rules are something like the machinery underlying our language, being at the same time the condition of possibility for language as well as the way by which we assess the correct linguistic uses. We apply the Wittgensteinian method by way of examining the normative function of grammatical propositions in particular cases. The primary aim of this exam is to show the most usual missteps of the philosophy of logic. This way we expect to expound Wittgenstein’s minimalist vision of what logic, grammar and normativity are: logic exhibits ordinary language with the purpose of presenting itself as the parameter by which the correction of all further uses should be assessed.
