Verdade e retórica em Chaim Perelman

Abstract

The purpose of this dissertation is to focus only on a specific task: to examine a part of Chaïm Perelman’s work (1912 - 1984) with a goal of finding some elements that allow us to formulate a notion of truth as a kind of justified decision in rhetorical way. In part, this task is made difficult by his New Rhetoric that does not have the pretension of being a theory of the truth as it clearly is a theory of mediated values in an argumentative way. The truth is not the main subject in the author’s thought; hence it was necessary, in certain way, to create this notion from his texts. However, it was not intended to suggest a theory of the truth but only to suggest some elements to make us to think about notion of truth with a certain rhetorical vocation, while it is examined, at the same time, how the Perelman’s thought give support to this idea. This dissertation looks for some tracks and certain consequences of this notion of truth constructed or consolidated from an argumentative process in the Right, Human Sciences and the view of the philosophy contemporary that is noticed in discussions produced by some versions of pragmatism.
