 Taking “aesthetic object” to mean “work of art”, the underlying ontology isn’t a sense-datum ontology or a mixed-category ontology at all. Several of the postulates—2, 4, and 6; possibly 3 and 7—are in fact prima facie incompatible with a sense-datum ontology. Rather, what 1–7 strongly suggest is that a work of art is a physical object: it’s perceptible, publicly or inter-subjectively available in both time and space, can appear differently from different points of view and at different times, may not be exhaustively understood on any given occasion, has properties that may be correctly or incorrectly perceived, and is such that attributions to it obey the law of non-contradiction.
