How do you define art? One story that helps me understand the very human concept of artistry is the painting of an old chair. Consider any old chair that you could buy for a song at a thrift shop or find at the curbside on garbage collection day. For all intents and purposes the chair has almost no value. But suppose Van Gogh were to have made a painting of that same chair in his inimitable style. That painting would be priceless though its subject be worthless. That is the paradox and the logic behind what we call art: transforming the ordinary into the extraordinary, making concepts truly sublime.
