“If the Martians ever find out how human beings think, they'll kill themselves laughing.”

“If your children ever find out how lame you really are, they'll murder you in your sleep.”

“No one must ever fancy another human being so much more evil than themselves that killing was justified.”

“And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal.”

“Worry about the things you can control; the rest will either work themselves out, or they'll kill you. Either way, no more worries.”

“I doubt we will ever be forgiven. All I hope is – they'll remember we were human beings”
