How do you judge Christo and Jean-Claude’s project to build gates in Central Park? Is it “possible for the project, once completed, to fail aesthetically. Is there a wrong way to arrange 7,500 gates in Central Park? If not, then in what sense is its realization an artistic success? Proposition: If difference in a work of art does not affect its value as art, then maybe it isn’t art to begin with. If Beethoven had written di-di-di-deem rather than di-di-di-dum, the result would have been not merely different but discernibly worse. If Shakespeare had written “Should I or shouldn’t I” rather than “To be or not to be,” the result would have been not merely different but worse. And if Raphael had painted Plato and Aristotle out of proportion with the rest of the figures in The School of Athens, or if he’d painted Aristotle gesturing up and Plato gesturing down, rather than vice-versa, the result would have been not merely different but worse.”
