"If you look out of the window as a human being, at nature, all of nature is unconditionally and absolutely beautiful. Whatever it is. Whether it’s a jungle, a desert, the arctic waste, or your own backyard, the only ugly things you will ever see are things made by man. And if, from your earliest age looking at the world you see yourself as a member of a species that can only uglify and spoil the world, it gives what psychiatrists would call a deep sense of guilt. And guilt, as anyone knows, is the major cause of aggression. That’s why you get violent. Because you’re guilty. You feel worthless. And you feel worthless if you don’t believe you’re part of a species that is actually capable of creating beauty. Which we are. In terms of architecture, music, painting, and all kinds of things, beauty is possible. And is good."
