Quote from : Speaker for the Dead Book

I don't think it has anything to do with truth, Olhado. It's just cause and effect. We never can sort them out. Science refuses to admit any cause except first cause-knock down one domino, the one next to it also falls. 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.
