Rhetoric, argumentation, and persuasion in a multimodal perspective
Résumé
The study of multimodal argumentation and rhetoric raises difficult issues due to the hegemony of the verbal in argumentation and rhetoric. From this point of view, it is not sufficient to say that such study implies the analysis of the “interactions” between verbal and iconic elements, since their contribution to multimodality is hardly balanced. This chapter addresses two issues: First, the relationship between rhetoric and argumentation. Based upon a discussion of authors who have tried to fill the gap between rhetoric and argumentation, it would seem that rhetoric could be useful for argumentation thanks to the persuasiveness that it provides. However, if images are persuasive, can they also be argumentative? Second, the relationship between verbal and visual rhetoric will be discussed from the debate in French-speaking countries between “transpositionists” and “antitranspositionists.” This issue can be resolved if we consider that rhetoric is not intrinsically linguistic, but that it consists rather of cognitive operations that can be realised both verbally and visually.
