Many years ago Meyer Schapiro argued that there was a radical difference between arts spiritual value and its commercial value. He warned against the nihilistic effect of collapsing their difference. I will argue that today, in the public mind, and perhaps in the unconscious of many artists, there is no difference. The commercial value of art has usurped its spiritual value, indeed, seems to determine it. Arts esthetic, cognitive, emotional and moral value — its value for the dialectical varieties of critical consciousness — has been subsumed by the value of money.
