This paper discusses how an understanding of Jung's psychological types is important for the relevance of Gilbert's multi-modal argumentation theory. Moreover, it highlights how the types have been confirmed by contemporary neuroscience and cognitive psychology. Based on Gilbert's approach, I extend multi-modal argumentation to the area of legal argumentation. It seems that when we leave behind the traditional fortress of “logical” legal argumentation, we "discover" alternate modes that have always been present, concealed in the theoretically underestimated rhetorical skills of arguers.

The question of emotion in argumentation has received considerable attention in recent years. But there is a tension between the traditional normative role of informal logic, and the inclusion of emotion which is viewed as notoriously unstable. Here I argue that that, a] there is always emotion in an argument; b] that the presence of emotion is a good thing; and c] that we can and ought model and teach the use of emotion in Argumentation Theory.
