"Let each listener just open his ears and think of anything. If everything goes well, the music will then capture his thinking, and at least give form, even if not substance, to it. And it might very well be that producing frames of thought within which important ideas may take root, flourish and breed is, in the long run, even more effective than just putting forward important ideas. Maybe music is good for something, after all."
