Can one understand explanations of aesthetic value via testimony? Exploration of an issue from Sosa Epistemic Explanations Ch.1

Abstract Sosa holds one may rationally want to understand how the specific features of a particular artwork ground its aesthetic value, and that this understanding cannot be gained at second-hand. Such understanding requires one to have insight into the link between grounding features and that value, and this can only be gained through first-hand engagement with the artwork. I distinguish two senses of second-hand. In one sense Sosa is correct that one cannot understand why P at second-hand: one must have insight oneself into the link between explanans and explanandum, and this is an exercise of one’s own mental power. But this allows another sense in which understanding may be gained at second-hand, via a description of an artwork provided to one through testimony. I argue that an expert can attain understanding of how key features of an artwork ground its aesthetic value from a suitably rich description of it. Sosa has misidentified the epistemic good that can only be obtained from first-hand engagement with an artwork. This is not understanding of what makes it good, but an enjoyable episode of aesthetic appreciation of it.
