During the last decade, one source of debate in argumentation theory has been the notion that there are different modes of arguing that need to be distinguished when analyzing and evaluating arguments. Visual argument is often cited as a paradigm example. This paper discusses the ways in which it and modes of arguing that invoke non-verbal sounds, smells, tactile sensations, music and other non-verbal entities may be defined and conceptualized. Though some attempts to construct a ‘multimodal’ theory of argument are criticized, it advocates for an argumentation theory that makes room for visual arguing and for other non-verbal modes that have not been explored in depth. In the process, the paper provides a method for identifying the structure of multimodal arguments and argues that adding modes to our theoretical tool box is an important step toward a comprehensive account of argument

Both 'persuasion' and 'rational convincing' play a major role in argumentative discourse but only the latter is said to constitute argument and be amenable to traditional logical analysis. I argue against this assumption by showing that there are many paradigmatic instances of persuasion which are best understood as implicit arguments. So understood, acts of persuasion can conform to well recognized argument schemata and are best assessed accordingly. I shall argue that the attempt to distinguish arg ument and persuasion is fraught with difficulties. I contrast my conclusions with those of authors like Gilbert, Johnson, and Johnson and Blair.
