If it is the case then viewer can project "masterpiece" to be contained in the piece of junk. Artist projects subjectivity in the creation. Viewers projection does not change the immanent value of artwork. For me artwork does contain independent set of valuable 'information' for human brain, which Clive Bell called 'Significant Form'. His description of it was not broad enough to cover all art forms from the point of global theory. Boris Shoshensky
It is indeed the case,just as, apparently, you decide that something is a piece of junk. i like the significant form concept myself but it's so convenient and easy. All you need to do is proclaim that the object has significant form and that is just as subjective as saying it's all a matter of empathy. But of course, as Worringer points outs, our sense of significant form is really inherited from our canon based on the Greco-Roman past and thus is too limited. The one thing we can say for sure is that inert objects do not possess aesthetic qualities. They may have qualities of form: line shape and texture, etc., that we call aesthetic and thus mirror back to the objects but as objects they are just so much material and in themselves, meaningless. The immanent value of an artwork is also assigned to it. wc
