ABSTRACT While literature is often used as a source of examples and illustrations across disciplines, literary studies tends to be underrepresented in interdisciplinary exchanges. Perhaps the reason lies in a lack of understanding what actually is the expertise of literary studies and how this can be useful in interdisciplinary settings. In this article, I propose to outline the expertise of literary scholars through concepts of 4E cognition and to devise a proposal for how such expertise could successfully shape the epistemic common ground of social cognition of experts in interdisciplinary dialogue. Literature involves metacognition centrally through its language style, the design of the narrative and its links to other texts, and literary scholars have the expertise in formulating exactly how this works – in a non-mimetic way – through the analysis and interpretation of literary texts. This very particular expertise and practice of literary scholars enables literary texts to be proposed as a boundary object in interdisciplinary dialogues through a shared epistemic common ground. For this argument, I build on earlier theoretical work in 4E cognition and predictive processing and my experience running interdisciplinary workshops on that model.
