Less known than 4'33" being "silent" (which it's not) is that John Cage was an anarchist.

"Both Fuller and Marshall McLuhan knew, furthermore, that work is now obsolete. We have invented machines to do it for us. Now that we have no need to do anything what shall we do? Looking at Fuller's Geodesic World Map we see that the earth is a single island. Oahu. We must give all the people all they need to live in any way they wish. Our present laws protect the rich from the poor. If there are to be laws we need ones that begin with the acceptance of poverty as a way of life. We must make the earth safe for poverty without dependence on government."
