Perceptually Indistinguishable Counterparts

Danto confronts the problem of Perceptually Indistinguishable Counterparts. The strongest example of such, I think, was his reference to the "artwork" Rauschenberg's Bed, a work of art which is, quite literally, a bed spattered with paint.

At first glance, the work appears to merely be a bed that was mutilated in a tragic paint accident. But someone in the artworld, whatever that may be, identified it as a work of art. (Having viewed it myself, I cannot consider it a work of art; but that is another debate. For now, I shall operate under the assumption that it is, indeed, a work of "art.")

How are we to distinguish an average bed from Rauschenberg's Bed? Simply put: it is in the theory of art. Under some working definition of what "Art" is, Rauschenberg's Bed is included in the category of Art, separate and distinct from the general category of "beds."

In other words, these Perceptually Indistinguishable Counterparts are NOT CONCEPTUALLY Indistinguishable Counterparts. It is in the CONCEPTION or THEORY of Art that Art is separated from not Art.

I must admit: this concept makes sense. Having a conception or theory of art that distinguishes Art works from things that are not Art. So the question then becomes: What concept or theory of art should we use? Or must be grapple with that question on our own?
