Great art, for those who insist upon this rather philistine concept (as if un-great art were unworthy of even their most casual and ill-informed attention), makes us stand back and admire. It rushes upon us pell-mell like the work of Rubens or Tintoretto or Delacroix, or towers above us. There is of course another aesthetic: the art of a Vermeer or a Braque seeks not to amaze and appal but to invite the observer to come closer, to close with the painting, peer into it, become intimate with it. Such art reinforces human dignity.
