The primacy of the image has been degraded. I'm speaking of painting mostly here. Modern arts quality can only be described in words, transcendly beautiful art needs no explanation for a person who knows nothing about the art, medium, artist, or it's history. If a piece of art cannot presumably be appreciated at some level by a small child, a hunter-gather, a retard, a poor individual, a rich individual, a art critic, a individual from the distant past, a woman, ect. than it is missing something essential.
