Abstract

I used traditional logic to examine some issues of the dynamics of argumentation, such as the possible outcomes of a debate, the influence of strengthening and weakening of propositions on the possible outcomes of a debate, and the influence of inclusion and exclusion of premisses on the possible outcomes of a debate. As the logical square plays an important role in the dynamics of argumentation, I extended it to the classical propositional case.

Keywords: Argumentation, dynamics, syllogistic, logical square.
