"Some artists ... make their work a mere showcase for a clever technique in which little is risked and less is communicated.  Some artists merely become experts in their medium, working clay or stone or wood or paint as proficiently and effortlessly as an ordinary craftsman.  And some artists try to make something out of nothing, order out of chaos, demanding of themselves that they ably communicate structure and composition, colour (sic) and balance, and that each piece they create serve to communicate a predetermined issue as well.  A piece of art asks people to stop and look in a world of moving images.  If people take the time to pause before canvas, bronze, glass, or wood, a worthy effort is one which does something more than act as nonverbal panegyric [formal or elaborate praise] to the talents of its creator.  It doesn't call for notice. It calls for thought."
