My purpose here is to describe a type of argument characterized by the fact that one of its premises is a directive—i.e. what is expressed by a directive sentence: a general instruction how to proceed or act. This directive premise brings an ostensive mechanism for the inclusion of visual or multimodal elements in an argument. If an argument is an invitation to inference, by using such a directive utterance the addresser is inviting the addressee to make an inference from an (...) image, not from a proposition. Hence I will call them arguments from ostension or from deixis. (shrink)

La oposición a una estricta separación entre las dimensiones dialéctica y retórica de la actividad argumentativa es una de las aportaciones más destacadas y peculiares de la denominada escuela holandesa sobre argumentación. Frans H. van Eemeren y Peter Houtlosser reaccionaron contra una separación estricta entre dialéctica y retórica en varios trabajos, pero uno de los más inspiradores es sin duda su artículo “William the Silent’s argumentative discourse” (1998) presentado en la ciudad de Ámsterdam con ocasión de la cuarta conferencia organizada (...) por la International Society for the Study of Argumentation (ISSA). Sobre este tema siguieron investigando para presentar un análisis de la perspectiva dialéctica inherente al caso de Guillermo I de Orange en un congreso de la Japan Debate Association en Tokio (van Eemeren y Houtlosser, 2000).

I will analyze the role of ostension in argumentation. Ostension involves gestures, bearing, postures, facial expressions, etc.; thus it can be argued that ostension can introduce non-verbal modes of argument, giving rise to multimodal arguments. Acts of ostension can be considered as a kind of speech acts according to the account in Wittgenstein’s Philosophical Investigations §27. As such they can provide the premises of a certain sort of arguments. We have to distinguish the proper act of ostension from both its (...) content and the object of ostension. While the latter can serve as evidence, as support for a linguistic claim without being part of it, as Dove points out, the act of ostension is a genuine act of arguing since to argue is to present something as a reason for something else. Acts of ostension are not assertive but directive acts, and so their content is not a statement but what I call an imperative. Thus I contend that imperatives can act as premises in some kind of arguments. Finally I will discuss whether arguments by ostension may be taken to be a kind of multimodal arguments. (shrink)
