“He’d undone all he could. You can be sorry, and you can be forgiven, but you can’t call back the futures that your bad decisions lost”

“It's not enough just to laugh at good fortune and say, 'Enough already.' You have to really mean it -- that you have enough. And because you mean it, you take the surplus and you give it away. Similarly, when bad fortune comes, you bear it until it becomes unbearable -- your family is hungry, or you can no longer function in your work. And then again you say, 'Enough already,' and you change something. You move; you change careers; you let your spouse make all the decisions. Something. You don't endure the unendurable.”

“I would carry some of it if I could, Bean said silently. Like I did today, you can turn it over to me and I’ll do it, if I can. You don’t have to do this alone.Only even as he thought this, Bean knew it wasn’t true. If it could be done, Ender was the one who would have to do it. All those months when Bean refused to see Ender, hid from him, it was because he couldn’t bear to face the fact that Ender was what Bean only wished to be — the kind of person on whom you could put all your hopes, who could carry all your fears, and he would not let you down, would not betray you.I want to be the kind of boy you are, thought Bean. But I don’t want to go through what you’ve been through to get there.”

“Free will doesn’t exist. Only the illusion of free will, because the causes of our 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 directions, you can never find where the casual chain begins. So you think, That domino fell because it wanted to.”

“Personal affection is a luxury you can have only after all your enemies are eliminated. Until then, everyone you love is a hostage, sapping your courage and corrupting your judgment.”

“Miro, I'm so sorry. I always felt such pity for you humans because you could only think of one thing at a time and your memories were so imperfect and . . . now I realize that just getting through the day without killing somebody can be an achievement."It gets to be a habit. Most of us manage to keep our body count quite low. It's the neighborly way to live.”
