'What a few people know now is that there are ways of thinking that we don't yet know about. Nothing could be more important or precious than that knowledge, however unborn. The sense of urgency, the spiritual restlessness it engenders cannot be appeased. Surely, it's some of that energy which has spilled over into the radical art of this century. Through its advocacy of silence, reduction, etc., art commits an act of violence upon itself, turning art into a species of auto-manipulation, of conjuring — trying to help bring these new ways of thinking to birth.'
Susan Sontag, 'The Aesthetics of Silence'
