"(Performance) art is, perhaps, the first art phenomenon to clearly demonstrate that modern art has become antiquated. Modern art is based upon a single assumption. That the artwork is only what it is.It is not a picture or a metaphor for something else. It is, say, a photograph, first and only. Or, perhaps, it is a painting, first and only. This assumption still looms above us all. We automatically accept it. We fall back upon it whenever we have a problem in criticizing, accepting, or understanding a work of art."
