“saying you don't know or care about God is the same as saying you believe he doesn't exist, because if you had even a hope that he existed, you would care very much.”

“Like Santa Claus. You adults pretend he doesn't exist, but we know that he really does.”

“Wiggin really doesn't care as much about himself as he does about these other kids who aren't worth five minutes of his time.And yet this may be the very trait that makes everyone focus on him. Maybe this is why all those stories Sister Carlotta told him, Jesus always had a crowd around him.Maybe this is why I'm so afraid of Wiggen. Because he's the alien, not me. He's the unintelligible one, the unpredictable one. He's the one who doesn't do things for sensible, predictable reasons. I'm going to survive, and once you know that, there's nothing more to know about me. Him, though, he could do anything.”

“There's always moral instruction whether the writer inserts it deliberately or not. The least effective moral instruction in fiction is that which is consciously inserted. Partly because it won't reflect the storyteller's true beliefs, it will only reflect what he BELIEVES he believes, or what he thinks he should believe or what he's been persuaded of. But when you write without deliberately expressing moral teachings, the morals that show up are the ones you actually live by. The beliefs that you don't even think to question, that you don't even notice-- those will show up. And that tells much more truth about what you believe than your deliberate moral machinations.”

“I don't care how much you eat, Ender, self-cannibalism won't get you out of this school.”

“If God created our will, then he's responsible for every choice we make... So-- as I recall, the official philosophical answer is that free will doesn't exist. Only the illusion of free will, because the causes of hour behavior are so complex that we can't trace them back. If you've got one line of dominoes knocking each other down, one by one, then you can always say, look, this domino fell because that one pushed it. But when you have an infinite number of dominoes that can be traced back in an infinite number of directions, you can never find where the causal chain begins. So you think, That domino fell because it wanted to... Even if there is no such thing as free will, we have to treat each other as if there were free will in order to live together in society.”

“Never true,' Old Ben would say. 'Useful- now, there's something. Your mind might make a connection that is useful. But true is another matter. True implies that you have found a connection that exists independent of your apprehension of it, that would exist whether you noticed it or not. And I must say that I have never seen such a connection in my life. There are times when I suspect there are no such connections, that all links, bonds, ties, and similarities are creations of thought and have no substance.”
