" Art is innovation, and its history cannot be written except from a distance sufficiently great to perceive form and form-ratio. One might answer that art today is still an incessant violation of codes. But how are those violations legible if no one code ever settles into common use, that is, starts to behave like a language or another convention-based system for getting things done; like a style, in other words? There can be no artistic innovation unless someone else is not innovating. "
