“...it seemed a part of her life, to step from the ancient to the modern, back and forth. She felt rather sorry for those who knew only one and not the other. It was better, she thought, to be able to select from the whole menu of human achievements than to be bound within one narrow range.”

“She had always thought that if only people could communicate mind-to-mind, eliminating the ambiguities of language, then understanding would be perfect and there'd be no more needless conflicts. Instead she had discovered that rather than magnifying differences between people, language might just as easily soften them, minimize them, smooth things over so that people could get along even though they really didn't understand each other. The illusion of comprehension allowed people to think they were more alike than they really were. Maybe language was better.”

“Miro, I'm so sorry. I always felt such pity for you humans because you could only think of one thing at a time and your memories were so imperfect and . . . now I realize that just getting through the day without killing somebody can be an achievement."It gets to be a habit. Most of us manage to keep our body count quite low. It's the neighborly way to live.”

“As history shows us, when colonization is voluntary, people will self-select better than any testing system. It’s like those foolish attempts to control immigration to American based on the traits that were deemed desirable, when in fact the only trait that defines Americans historically is “descended from somebody willing to give up everything to live there.” Willingness is the single most important test.”

“The tribe is whatever we believe it is. If we say the tribe is all the Little Ones in the forest, and all the trees, then that is what the tribe is. Even though some of the oldest trees here came from warriors of two different tribes, fallen in battle. We become one tribe because we say we're one tribe."Ender marveled at his mind, this small raman [member of another sentient species]. How few humans were able to grasp this idea, or let it extend beyond the narrow confines of their tribe, their family, their nation.”

“The little bitch. She didn't have her files in another computer. She kept everything she knew inside her head.”

“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.”
