The paper focuses on the role of both emotional and metaphorical processes in reasoning. The aim of the paper is to present an extension of the argumentative theory of reasoning proposed by Mercier and Sperber (2011). In order to advance an integrated model of the roles of metaphors and emotions in argumentation, the paper argues that it is possible to ascribe not only a negative role to emotions and metaphors, but also a positive one. Far from being just a source of fallacies in reasoning, indeed, both emotions and metaphors – considered as framing and reframing strategies – can play a constructive role in argumentation, by enhancing their creative power.
