On Some Aristotelian Sources of Modern Argumentation Theory

Abstract

Although he does not provide a general analysis of argumentation, Aristotle is a highly influential source of modern argumentation theory. In his treatises the Topics, the Sophistical Refutations and the Rhetoric, Aristotle presents complementary aspects of a theory of sound arguments that are seen as the most effective means of persuasion. Aristotle’s central notion of a deductive argument (sullogismos) does not include references to an addressee, the situative context or non-verbal aspects of communication, and thus differs from some modern views on argumentation. A deductive argument in the Aristotelian sense is a sequence of intellectual steps where the conclusion follows of necessity from the premises. Aristotle does not relativize or relax this notion but takes other factors into account by providing supplementary theoretical elements. For example, he reflects on acceptable premises (endoxa), the adjustment of rhetorical arguments to the horizon of the audience, methods of finding premises on the basis of argumentative schemes (topoi), the use of non-argumentative means of persuasion, and a framework of implicit discourse rules. Many of these themes are, albeit under a different name, still discussed in modern argumentation theory.
