“I've had your tears with mine, and you've had mine with yours. I think that's more intimate even than a kiss.”

“I can see by your face that I'll never persuade you. And that's surprising, because usually you at least try to see my side."I can see your side," said Cecily. "I've got a much clearer view of it than you do, from over here on my side.”

“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.”

“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.

The illusion of comprehension allowed people to think they were more alike than they really were. Maybe language was better.”

“Do the gods of different nations talk to each other?...Is there some annual get-together where they compare each other's worshippers? Mine will bow their faces to the floor and trace woodgrain lines for me, says one. Mine will sacrifice animals, says another. Mine will kill anyone who insults me, says a third. Here is the question I think of most often: "Are there any who can honestly boast, My worshippers obey my good laws, and treat each other kindly, and live simple generous lives?”

“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.”

“I know, you've been here a year, you think these people are normal. Well, they're not. WE'RE not. I look in the library, I call up books on my desk. Old ones, because they won't let us have anything new, but I've got a pretty good idea what children are, and we're not children. Children can lose sometimes, and nobody cares. Children aren't in armies, they aren't COMMANDERS, they don't rule over forty other kids, it's more than anybody can take and not get crazy.”
