Aesthetic properties figure prominently in our daily lives, our conversations and many actions we take. Yet theoretical disagreement prevails over their nature, their variety, their epistemic and metaphysical status. This overview highlights the heterogeneity of aesthetic properties and examines repercussions for explanation. Aesthetic properties belong to natural objects or scenes, to artworks in any medium, to artefacts and built environments across historical eras; and they draw a wide variety of responses such as our perceptions, emotions or imaginative thought. Historicism about (...) artworks carries over to at least some aesthetic properties that depend on facts of their broader historical context just as works do. One issue is whether aesthetic properties can be demarcated solely in terms of non-aesthetic properties. If not, explanations of aesthetic properties need to draw on other aesthetic notions such as aesthetic experience, attention, judgement or value. The paper examines several accounts of aesthetic value to show how they extend to aesthetic properties. The paper concludes with an overview of the current metaphysical debate between realists and non-realists about aesthetic properties. (shrink)
