“Listen to me, Jez. There's no reason for you to die-"
Wood… poison."
No it isn't! Not to humans. And you're half human. You're vampire enough to survie something that would kill a human, but you're human enough not to be poisoned by wood.”

“If you're depressed or anxious, you're not weak and you're not crazy -- you're a human being with unmet needs.”

“In you, humanity is precarious; and so, in dread and in shame, you kill the animal in you. And its slaughter poisons you.”

“Rant would tell people: 'You're a different human being to everybody you meet.”

“I guess I can't, or my subconscious can't, even imagine a warless world. The best it can do is substitute one kind of war for another. You said, no killing of humans by other humans. So I dreamed up the Aliens. Your own ideas are sane and rational, but this is my unconscious you're trying to use, not my rational mind. Maybe rationally I could conceive of the human species not trying to kill each other off by nations, in fact rationally it's easier to conceive of than the motives of war. But you're handling something outside reason. You're trying to reach progressive, humanitarian goals with a tool that isn't suited to the job. Who has humanitarian dreams?”

“In America, if a Democrat even thinks you're calling him liberal he grabs an orange vest and a rifle and heads into the woods to kill something.”

“I think that when you are famous every weakness is exaggerated. … Goethe said, "Talent is developed in privacy," you know? And it's really true. … Creativity has got to start with humanity and when you're a human being, you feel, you suffer. You're gay, you're sick, you're nervous or whatever.”

“The inventor of the mirror poisoned the human heart.”

“It's all right to make mistakes, you're only human
Inside everybody's hiding something.”

“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.”
