“What good were the rules of time when the rules of magic contradicted them.”

“There are rules to everything, even if nobody made them up, even if nobody calls it a game. And if you want things to work out well, it's best to know the rules and only break them if you're playing a different game and following those rules.”

“I think it's a rule that it's socially acceptable to wet yourself when aliens enter your mind for the first time. If it wasn't already, it is now.”

“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.”

“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.”

“If you read to your kids, you'll make readers out of them, partly because they'll associate reading with good parent-time.”

“Someday stars will wind down or blow up. Someday death will cover us all like the water of a lake and perhaps nothing will ever come to the surface to show that we were ever there. But we WERE there, and during the time we lived, we were alive. That's the truth - what is, what was, what will be - not what could be, what should have been, what never can be.”
