“But when it comes to human beings, the only type of cause that matters is final cause, the purpose. What a person had in mind. Once you understand what people really want, you can't hate them anymore. You can fear them, but you can't hate them, because you can always find the same desires in your own heart.”

“There's only one thing that will make them stop hating you. And that's being so good at what you do that they can't ignore you.”

“When you really know somebody you can’t hate them. Or maybe it’s just that you can’t really know them until you stop hating them.”

“There was no doubt now in Ender's mind. There was no help for him. Whatever he faced, now and forever, no on ewould save him from it. Peter might be scum, but Peter had been right, always right; the power to cause pain is the only power that matters, the power to kill and destroy, because if you can't kill then you are always subject to those who can, and nothing and no one will ever save you.”

“No human being, when you understand his desires, is worthless. No one's life is nothing. Even the most evil of men and women, if you understand their hearts, had some generous act that redeems them, at least a little, from their sins.”

“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.”

“People above you, they never want to share power with you. Why you look to them? They give you nothing. People below you, you give them hope, you give them respect, they give you power, cause they don't think they have any, so they don't mind giving it up.”
