Argumentation Moods
Argumentation is an act of communication performed by a speaker aiming to persuade a listener to accept or reject a proposition, named thesis, using another proposition, called argument, and a relation between them – the frame of argumentation. Argumentations are evaluated relatively to the pragmatic value of success and to the logical value of correctness. These values are independent of each other – namely, from the success of an argumentation, nothing can be inferred about its correctitude, and reciprocally. In order to establish the correctness of an argumentation, we can classify all argumentations into moods such as the syllogisms. A necessary condition for the correctitude of an argumentation is the validity of its mood. The validity of the argumentative moods is investigated using the reduction method established by Aristotle for syllogistic moods.
