Cognitive progress often involves reconfiguring a domain, bringing previously unrecognized likenesses, differences, patterns and discrepancies to light. I argue that the arts effect such reconfigurations, enabling us to discern and appreciate the importance of aspects of the domain that we had previously overlooked or underemphasized. I argue that so-called ‘aesthetic devices’ like metaphor, fiction, and exemplification figure in our understanding of science as well as art. We cannot do justice to our scientific understanding while denying that art and its devices function cognitively.
