When we inquire into the nature of works of art we can see at a glance that there is a good deal of evidence against aesthetic idealism, the view that artworks are, in the final analysis, imaginary objects in the minds of their creators. We believe, for instance, that the National Gallery not only contingently but in some sense necessarily weighs more than merely the sum of the empty building, the people in it, and the assorted fixtures. This sum must also include the weight of canvases, the oils on them, carved stone and marble, and so on, all of which add up to substantially more than nothing, which is at least the approximate weight of imaginary things. We know that it takes considerably more than a verbal utterance or acoustical blast to transport an artwork, and we also know that a visit to the gallery is not going to amount to an afternoon spent with wax figures of unicorns, flying horses, present and bald kings of France or, for that matter, talking teapots. In short, intuition protests against the idealist theory that if works of art are imaginary objects, they cannot be the things we go to see in the gallery; and if they are imaginary objects then, like a waxen Peter Pan, they are surely not art. Mellon and Meinong simply have different kinds of collections.
