Art is complicated. It can take years to grasp why an all-white painting by Robert Ryman is art. At the end of the day, however, everything you need to know about a work of art should be in it, not on a wall label or an explanation from an art dealer. This is one of the great things about artthe source of its mystery, lucidity, obdurateness, and its astonishing, seductive, silent power. And why I love doing what I get to do.
