Two radical ideas have been introduced into human thought. One of them is that energy and matter are pretty much the same sort of stuff. That\'s Einstein. The other is that revenge is a bad idea. Revenge is an enormously popular idea but, of course, Jesus came along with the radical idea of forgiveness. If you\'re insulted, you have to square accounts. So this invention by Jesus is as radical as Einstein\'s.

Billy covered his head with his blanket. He always covered his head when his mother came to see him in the mental ward - always got much sicker until she went away. It wasn’t that she was ugly, or had bad breath or a bad personality. She was a perfectly nice, standard-issue, brown-haired, white woman with a high school education. She upset Billy simply by being his mother. She made him feel embarrassed and ungrateful and weak because she had gone through so much trouble to give him life, and to keep that life going, and Billy didn’t really like life at all.

What I would really like to have been, given a perfect world, is a jazz pianist. I mean jazz. I don't mean rock and roll. I mean the never-the-same-twice music the American black people gave the world.

Where is home? I've wondered where home is, and I realized, it's not Mars or someplace like that, it's Indianapolis when I was nine years old. I had a brother and a sister, a cat and a dog, and a mother and a father and uncles and aunts. And there's no way I can get there again.
