"I am convinced that I cannot achieve beauty via a direct route; that can only be the result of deliberation. Otherwise, we would be back at the pure sound that creates happiness—which I don't believe in. That's the interesting thing about art: that somehow, you use your material to make something that results in something beautiful, via a path that no one has yet trodden. That means working with something that is improbable, where your predecessors would have said, 'You can't do that.' First you take a step towards ugliness and then, somehow or other, you wind up where it's beautiful."
