Abstract

Theoretical interest in Perelman's thought is linked, for the main part, to the place he accords to the notion of argumentation, defined in his work in reference to the Greek philosophy, as represented by Plato and Aristotle, in contrast to the assertions of the sophists and rhetors. He separates the notion of demonstration and that of argumentation and supports his position on an analysis of the debates which were common in the sophistic and rhetoric period.It is in different ways that the notion of argumentation comes into the work of Perelman. By taking up again the analysis of justice with the aim of removing the various strata of meaning which had accumulated on it as a result of the reductions of Plato and the dialectical analyses of Aristotle, Perelman showed that the theory of argumentation transcends the domain of right in which it is rooted and ought not be abandoned to lawyers only. Thus, he follows a train of thought to which he accords a certain nobilty in the name of the new rhetoric. This manner of considering the relationship of the moderns to the Greeks leads him to set up the notion of argumentation in his own texts, where it demonstrates a logical retreat which enables him to work back from Aristotle to Plato and from him to the rhetors and sophists, whose discourse is defined on the level of the self-referential.The exemplary character of Perelman's work is on account of this rehabilitation of argumentation in the old rhetoric which will be examined here
