“No one with him to tell him he must eat, he must go practice, he must sleep. Freedom. The trouble was, he didn't know what to do.”

“[Ruthie] ... if he was a good man, how could he leave me? So he must not be a good man. But if he isn't good, then why does it hurt so much to lose him?”

“Wiggin really doesn't care as much about himself as he does about these other kids who aren't worth five minutes of his time.And yet this may be the very trait that makes everyone focus on him. Maybe this is why all those stories Sister Carlotta told him, Jesus always had a crowd around him.Maybe this is why I'm so afraid of Wiggen. Because he's the alien, not me. He's the unintelligible one, the unpredictable one. He's the one who doesn't do things for sensible, predictable reasons. I'm going to survive, and once you know that, there's nothing more to know about me. Him, though, he could do anything.”

“He was known by three names. The official records have the first one: Marcos Maria Ribeira. And his official data. Born 1929. Died 1970. Worked in the steel foundry. Perfect safety record. Never arrested. A wife, six children. A model citizen, because he never did anything bad enough to go on the public record. The second name he had was Marcao. Big Marcos. Because he was a giant of a man. Reached his adult size early in his life. How old was he when he reached two meters? Eleven? Definitely by the time he was twelve. His size and strength made him valuable in the foundry,where the lots of steel are so small that much of the work is controlled by hand and strength matters. People's lives depended on Marcao's strength. His third name was Cao. Dog. That was the name you used for him when you heard his wife, Novinha, had another black eye, walked with a limp, had stitches in her lip. He was an animal to do that to her. Not that any of you liked Novinha. Not that cold woman who never gave any of you good morning. But she was smaller than he was, and she was the mother of his children, and when he beat her, he deserved the name of Cao. Tell me, is this the man you knew? Spent more hours in the bars than anyone but never made any friends there, never the camaraderie of alcohol for him. You couldn't even tell how much he had been drinking. He was surly and short-tempered before he had a drink and he was surly and short-tempered right before he passed out-nobody could tell the difference. You never heard of him having a friend, and none of you was ever glad to see him come into a room. That's the man you knew, most of you. Cao. Hardly a man at all. A few men, the men from the foundry in Bairro das Fabricados, knew him as a strong arm as they could trust. They knew he never said he could do more than he could do and he always did what he said he would do. You could count on him. So, within the walls of the foundry, he had their respect. But when you walked out of the door, you treated him like everybody else-ignored him, thought little of him. Some of you also know something else that you never talk about much. You know you gave him the name Cao long before he earned it. You were ten, eleven, twelve years old. Little boys. He grew so tall. It made you ashamed to be near him. And afraid, because he made you feel helpless. So you handled him the way human beings always handle things that are bigger than they are. You banded together. Like hunters trying to bring down a mastodon. Like bullfighters trying to weaken a giant bull to prepare it for the kill. Pokes, taunts, teases. Keep him turning around. He can't guess where the next blow was coming from. Prick him with barbs that stay under his skin. Weaken him with pain. Madden him. Because big as he is, you can make him do things. You can make him yell. You can make him run. You can make him cry. See? He's weaker than you after all. There's no blame in this. You were children then, and children are cruel without knowing better. You wouldn't do that now. But now that I've reminded you, you can clearly see an answer. You called him a dog, so he became one. For the rest of his life, hurting helpless people. Beating his wife. Speaking so cruelly and abusively to his son, Miro, that it drove the boy out of his house. He was acting the way you treated him, becoming what you told him he was. But the easy answer isn't true. Your torments didn't make him violent - they made him sullen. And when you grew out of tormenting him, he grew out of hating you. He wasn't one to bear a grudge. His anger cooled and turned into suspicion. He knew you despised him; he learned to live without you. In peace. So how did he become the cruel man you knew him to be? Think a moment. Who was it that tasted his cruelty? His wife. His children. Some people beat their wife and children because they lust for power, but are too weak or stupid to win power in the world.”

“I saw what Andrew did in our family. I saw that he came in and listened and watched and understood who we were, each individual one of us. He tried to discover our need and then supply it. He took responsibility for other people and it didn't seem to matter to him how much it cost him. And in the end, while he could never make the Ribeira family normal, he gave us peace and pride and identity. Stability. He married Mother and was kind to her. He loved us all. He was always there when we wanted him, and seemed unhurt by it when we didn't. He was firm with us about expecting civilized behavior, but never indulged his whims at our expense. And I thought: This is so much more important than science. Or politics, either. Or any particular profession or accomplishment or thing you can make. I thought: If I could just make a good family, if I could just learn to be to other children, their whole lives, what Andrew was, coming so late into ours, then that would mean more in the long run, it would be a finer accomplishment than anything I could ever do with my mind or hands.""So you're a career father," said Valentine."Who works at a brick factory to feed and clothe the family. Not a brick-maker who also has kids. Lini also feels the same way... She followed her own road to the same place. We do what we must to earn our place in the community, but we live for the hours at home. For each other, for the children.”

“An enemy, Ender Wiggin," whispered the old man. "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 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.”

“Maezr smiled. "A hundred years ago, Ender, we found out some things. That when a commander's life is in danger he becomes afraid, and fear slows down his thinking. When a commander knows that he's killing people, he becomes cautious or insane, and neither of those help him do well. And when he's mature, when he has responsibilities and an understanding of the world, he becomes cautious and sluggish and can't do his job. So we trained children, who didn't know anything but the game, and never knew when it would become real. That was the theory, and you proved that the theory worked.”
