Apart from nuances that may not be relevant in the context of a particular discussion, many statements of aesthetic criticism, linguistic or philosophical, will be interchangeable. One critic might say that artwork A falls short in respect of exhibiting property P, whereas another might say instead that the predicate "P" is not properly applicable to artwork A, or artwork A lies outside the range of artworks to which the expression "P" applies. So we can shift back and forth between talk about properties (philosophical items in an ontology) and talk about predicates (expressions in a language). When the differences in nuance do begin to matter, I think that one has crossed the border from aesthetic criticism to metaphysics.
