“So from then on, he looked at all his choices and said, What would a good person do, and then did it. But he has now learned something very important about human nature. If you spend your whole life pretending to be good, then you are indistinguishable from a good person. Relentless hypocrisy eventually becomes the truth.”

“My husband is a good man," she said. "It's important to him to be a good man. He has to not only be good, he has to believe that he's good. In the eyes of God, in my eyes, in his parents' eyes, in his own eyes. Good.”

“When you have wisdom that another person knows that he needs, you give it freely. But when the other person doesn't yet know that he needs your wisdom you keep it to yourself. Food only looks good to a hungry man.”

“It is easy to say that you can adopt the whole human race as your children, but it is not the same as living in a home with a child and shaping all you do to help him learn to be happy and whole and good. Don't live your life without ever holding a child in your arms, on your lap, in your home, and feeling a child's arms around you and hearing his voice in your ear and seeing his smile, given to you because you put it into your heart.”

“I am your enemy, the first one you've ever had who was smarter than you. There is no teacher but the enemy. No one but the enemy will tell you what the enemy is going to do. No one but the enemy will ever teach you how to destroy and conquer. Only the enemy shows you where you are weak. Only the enemy tells you where he is strong. And the only rules of the game are what you can do to him and what you can stop him from doing to you. I am your enemy from now on. From now on I am your teacher. I will devise the strategy of your army, and you will learn to be quick and discover what tricks the enemy has for you. Remember, boy. From now on the enemy is more clever than you. From now on the enemy is stronger than you. From now on you are always about to lose.”

“I would carry some of it if I could, Bean said silently. Like I did today, you can turn it over to me and I’ll do it, if I can. You don’t have to do this alone.Only even as he thought this, Bean knew it wasn’t true. If it could be done, Ender was the one who would have to do it. All those months when Bean refused to see Ender, hid from him, it was because he couldn’t bear to face the fact that Ender was what Bean only wished to be — the kind of person on whom you could put all your hopes, who could carry all your fears, and he would not let you down, would not betray you.I want to be the kind of boy you are, thought Bean. But I don’t want to go through what you’ve been through to get there.”

“What else should you be? Human beings didn't evolve brains in order to lie around on lakes. Killing's the first thing we learned. And a good thing we did, or we'd be dead, and the tigers would own the earth.”
