The Rhetorical Methodology of Perelman and Olbrechts-Tyteca’s Theory of Argumentation

Abstract

ABSTRACT Despite Perelman and Olbrechts-Tyteca’s well-known influence on argumentation studies, it is striking that their theory of argumentation no longer stands out as a living project in the field. On the one hand, critics argue that their theory is inherently relativistic and therefore incapable of aiding argument evaluation. On the other hand, critics argue that, even as a descriptive theory, it fails to sufficiently justify its own systematic ambitions. This article addresses these dual concerns by returning to one of the most neglected yet most innovative aspects of Perelman and Olbrechts-Tyteca’s theory of argumentation—its rhetorical methodology. Reconstructing two key aspects of this methodology in phenomenological terms, the author discusses that the theory of argumentation found in The New Rhetoric is a philosophically neutral framework for describing the already norm-laden practice of argumentation.
