Metaphor has been considered as a cognitive process, independent of the verbal versus visual mode, through which an unknown conceptual domain is understood in terms of another known conceptual domain. Metaphor might instead be viewed as a cognitive process, dependent on the mode, which leads to genuinely new knowledge via ignorance. First, I argue that there are two main senses of ignorance at stake when we understand a metaphor: we ignore some existing properties of the known domain in the sense (...) that we disregard or neglect them; we ignore some “non-existing” properties of the known domain in the sense that they are not a piece of information belonging to the known domain, but emerge in metaphor interpretation. Secondly, I consider a metaphor as a reasoning device, guiding the interpreters along a path of inferences to a conclusion, which attributes to the target some properties of the source. In this path, interpreters might discover the ignored existing properties of the known domain and/or recover the “non-existing” properties, inferring or imagining the missing piece of information. Finally, I argue that, especially in visual metaphors, this process is guided by a “sentiment of rationality”, tracking a disruption of existing familiar conceptualisations of objects and/or actions and a recovery of ignored properties.

“Image metaphor” is defined in Conceptual Metaphor Theory as a mapping of visual structure from one entity onto another based on the mental images they evoke. It is considered an exceptional, one-off phenomenon that can be distinguished clearly from prototypical conceptual metaphors. However, according to Perceptual Simulation Theory, all language, both literal and nonliteral, is understood partially by simulating in our minds what it would be like to actually perceive the things that are being described, which suggests that visualization is (...) not unique to image metaphor. As I argue in this article, the mental imagery invited by image metaphors is nevertheless likely to be particularly vivid, detailed, and complex, as well as involving more conscious and deliberate thought processes. Since it is hard to consider visualization in abstract terms, pictorial equivalents of image metaphors are used to support my claims. (shrink)
