Art has the power to change lives. It can redraw the boundaries of our public discourse and stretch the horizons of our private hearts. When you study its history and see the important role it has played in human development, you realize that art has the power to do anything, except make money. Mostly, though, it has the power to suck. Back when art was two carvings a year and whatever Michelangelo put out, it had to be really good. Now that everyone is an artist and all behavior is performance, no single unit of art has to do much work. It just has to be seen. Today is Friday, and the world is producing art on a larger scale than ever before. Won’t you tactfully remark on the size of the canvas with me?
