Abstract

Inter- and transdisciplinary (ITD) approaches represent promising ways to address complex global challenges, such as climate change. Importantly, arts–sciences collaborations as a form of inter and transdisciplinarity have been widely recognized as potential catalysts for scientific development and social change towards sustainability. However, little attention has been paid to the process of reasoning among the participants in such collaborations. How do participants in arts–science collaboration reason together to overcome disciplinary boundaries and to co-create interventions? This article investigates how inter- and transdisciplinary reasoning (or ITD reasoning) unfolded in a collaboration involving experts from the natural sciences, humanities, and the arts. We studied how collaborators reasoned through different understandings and experiences of climate change as well as through multiple ways of fostering motivation to take action via two co-designed artworks, HOMONEXUS (a participatory textile and acoustic installation) and GLACIER NEX US (a performance staging a dialogue between a melting glacier and a glaciologist). Our conclusions are threefold: (i) ITD reasoning can increase participants’ capacity to navigate often-unpredictable situations by cross-fertilizing ideas and overcoming blind-spots; (ii) humanities in arts–science collaborations can foster a more nuanced understanding of the differences and similarities of different knowledge systems as well as a deeper ecological understanding of sustainability problems; and (iii) the aesthetic experiences stimulated by arts–science interventions may help to raise awareness about the climate emergency and sustainable actions by providing pleasant and positive or dazzling and negative aesthetic experiences.
