Generalising across the arts is a tricky business. Can we really expect to find anything in common between, say, Ulysses, Der Rosenkavalier, the ‘Donna Velata’ and Donatello’s St George in virtue of which they are all works of art? As if that were not hard enough, try adding prints, films, dances and buildings and the problem becomes intractable. Yet traditionally the aim of aesthetics has been to undertake an abstraction from the properties of particular works of art, and of different forms of art, with precisely the hope of isolating just those general features which are supposed to characterise or define the nature of art itself. To discover defining, or even characteristic, properties of art, if such there be, presupposes an answer to even more basic, ontological, questions concerning what sorts of things or entities works of art are. Are they physical objects, ideas, universals, classes, or what?
