“Good people aren't good because they never cause harm to others. They're good because they treat others the best way they know how, with the understanding that they have.”

“Every time, I've won because I could understand the way my enemy though. From what they did. I could tell what they though I was doing, how they wanted the battle to take shape. And I played off of that. I'm very good at that. Understanding how other people think. - Ender Wiggin”

“That's what Father and Mother are, thought Nafai. They stay together, not because of any gain, but because of the gift. Father doesn't stay with Mother because she is good for him, but rather because together they can do good for us, and for many others.”

“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.”

“In philosophy class I think we finally decided that 'good' is an infinitely recursive term - it can't be defined except in terms of itself. Good is good because it's better than bad, though why it's better to be good than bad depends on how you define good, and on and on.”

“The strangest thing about humans is the way they pair up, males and females. Constantly at war with each other, never content to leave each other alone. They never seem to grasp the idea that males and females are separate species with completely different needs and desires, forced to come together only to reproduce Of course you feel that way. Your mates are nothing but mindless drones, extensions of yourself, without their own identity. We know out lovers with perfect understanding. Humans invent an imaginary lover and put that mask over the face of the body in their bed. That is the tradegy of language, my friend. Those who know each other only through symbolic representations are forced to imagine each other. And because their imagination is imperfect, they are often wrong, This is the source of their misery. And some of their strength, I think. Your people and mine, each for their own evolutionary reasons, mate with vastly unequal partners. Our mates are always, hopelessly, our intellectual inferiors. Humans mate with beings who challenge their supremcy. They have conflicts between mates, not because their communication is inferior to ours, but because they commune with each other at all.”

“In a way she actually preferred Peter to other people because of this. He always acted out of intelligent self-interest.”
