“As a species, we have evolved to survive. And the way we do it is by straining and straining and, at last, every few generaitons, giving brith to genius. The one who invents the wheel. And light. And flight. The one who builds a city, a nation, an empire...I'll put it bluntly. Human beings are free excpet when humanity needs them. Maybe humanity needs you. To do something. Maybe humanity needs me - to find out what you're good for.”

“Human beings are free except when humanity needs them. Maybe humanity needs you. To do something. Maybe humanity needs me—to find out what you're good for. We might both do despicable things, Ender, but if humankind survives, then we were good tools.”

“The selective voluntary blindness of human beings allows them to ignore the moral consequences of their choices. It has been one of the species' most valuable traits, in terms of the survival of any particular human community.”

“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.”

“Others find humanity by looking in their own hearts. Only lost souls need to search for it outside themselves.”

“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.”

“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.”
