“Most of us have learned to be dispassionate about evil, to look it in the face and find, as often as not, our own grinning reflections with which we do not argue, but good is another matter. Few have stared at that long enough to accept that its face too is grotesque, that in us the good is something under construction. The modes of evil usually receive worthy expression. The modes of good have to be satisfied with a cliche or a smoothing down that will soften their real look.”

“We, Equality 7-2521, were not happy in those year in the Home of the Students. It was not that the learning was too hard for us. It was that the learning was too easy. This is a great sin, to be born with a head which is too quick. It is not good to be different from our brothers, but it is evil to be superior to them. The Teachers told us so, and they frowned when they looked at us.”

“There's a Good Book about goodness and how to be good and so forth, but there's no Evil Book about how to be evil and how to be bad. The Devil had no prophets to write his Ten Commandments, and no team of authors to write his biography. His case has gone completely by default. We know nothing about him but a lot of fairy stories from our parents and schoolmasters. He has no book from which we can learn the nature of evil in all its forms, with parables about evil people, proverbs about evil people, folklore about evil people. All we have is the living example of people who are least good, or our own intuition.”

“Evil things often look beautiful. But that's because they've stolen the beauty from the good.... Evil isn't beautiful on its own.”

“It is well, I think, for us to learn to tell evil from good; but it has its price, as everything does. We leave our evil friend behind.”

“None of us is fully able to perceive the truth that shines through another person’s window, nor the falsehood that we may perceive as truth. Thus, we can easily mistake another’s good for evil, and our own evil for good.”
