Multimodal Argument as Dialogue

According to a dialectical approach to argumentation, a single argument can be seen as a dialogical "Why? Because!" sequence. Does this also apply to multimodal arguments? This paper focuses on multimodal arguments with a predominantly visual character and shows that dialogues are helpful for identifying and reconstructing arguments in multimodal communication. To include nonverbal arguments in dialectical argumentation theory, it is proposed to regard dialogue as mode-fluid. The account of multimodal argument as dialogue will be compared with Champagne and Pietarinen’s account of visual argument as movement.
