Formal Logic, Rhetoric аnd Rational Argumentation

Abstract

The theory of argumentation is supposed to be related to rationality. Traditionally, rationality was defined in terms of logic, and at the same time considered an essential part of the theory of argumentation. But dialectic, in its traditional sense, is also associated with rationality. Thus, rationality reveals the connection between two disciplines, rheto- ric as a theory of adequate communication and formal logic as a theory explaining the preservation of truth from premises to the conclusion. This unity of the two aspects of the dialectic conversation reveals the connection between the formal and material aspects of argumentation as a rational basis of scientific research.
