A linguagem privada nas Investigações Filosóficas.

Abstract

This dissertation analyzes the argument of private language in Wittgenstein's Philosophical Investigations in a broad and strict sense. To accomplish this task, it first presents a general characterization of the Philosophical Investigations as style, text and context; and consequently, the delimitative implications of the argument of private language and its theses within the work. In order to achieve this goal, the assistance of renowned national and international Wittgensteinian commentators was taken into account, and foreign literature was mostly used because it contains greater production on the subject in question. The work is composed of three parts, namely: first, it explains Wittgenstein and the Philosophical Investigations, trying to demonstrate in which points the aforementioned work distanced Wittgenstein from the Tractatus and discusses the thematic delimitation of private language within the aforementioned work, and its preliminary arguments; secondly, Wittgenstein is confronted with themes contiguous to the issue of private language with which his arguments are tested on the risk of falling into contradiction and inconsistency; thirdly, Kripke's methodological distinction on the private language argument with the skeptic's paradox in relation to Wittgenstein in the Philosophical Investigations was addressed. Finally, it reaffirms the philosophical consequences of the private language argument both in language and in other fields of knowledge.
