Metaphor is considered a figurative use of language, a term that seems to recall the imagistic dimension characterizing this kind of utterances. Tzvetan Todorov (1967) speaks of “figure” as “visibility of speech”: as a figure, metaphor provides a kind of figurability to what is communicated. As Paul Ricoeur wrote in La métaphore vive (Ricoeur, 1975), metaphor makes “speech appear”. Precisely because of the reliance on the idea of figure, it is therefore not surprising that discussions on metaphor often refer to the role that mental images play in their comprehension. A long tradition holds that the formation of a mental image is fundamental for the comprehension of certain kinds of metaphor. This is the case of authors such as Aristotle, Gianbattista Vico, George W. F. Hegel or Friedrich Nietzche in the classical tradition, or Raymond Gibbs, Daniel Gleason and Marcel Just in the more recent experimental tradition (Aristotle, 2014; Gleason, 2009). By contrast, for other authors, mental imagery is, at most, a tangential phenomenon, playing no important role in metaphor comprehension. This is the position of several authors such as I. A. Richards (1936), for whom mental imagery “is a mere distraction and of no service” (Richards, 1936, p. 130). Pragmatics today follows this latter direction and most accounts of metaphor omit any mention of mental imagery (Grice, 1975; Searle, 1979; Glucksberg, 2001) and explain the comprehension of metaphor entirely in terms of implicitly communicated propositions (Sperber & Wilson, 2008). Within the framework of Relevance Theory, Robyn Carston (2018) takes up the problem and discusses directly what role, if any, mental imagery plays in under standing metaphor, concluding that although mental images can be activated an Metaphor is considered a figurative use of language, a term that seems to recall the imagistic dimension characterizing this kind of utterances.

In this paper, starting from Carston (2018) and Wilson and Carston (2019), we will discuss the role of mental images in the comprehension of certain kinds of metaphor. In the first section we will analyze the treatment of metaphor in pragmat ics, paying particular attention to Relevance Theory. In the second section we will compare the hypotheses of Carston (2018) and Green (2017) on the role of mental images in the comprehension of metaphors and we will propose a synthesis between the two positions. In the third and fourth sections we will discuss some problems that mental images pose to pragmatics, showing their necessity through recourse to an experimental dimension. Finally, in the fifth section we will discuss the notion of mental image, proposing a characterization that can make this notion suitable for its insertion in the domain of analysis of pragmatics.
