“We're all tools in somebody's kit. But that doesn't mean we can't make tools out o other people. Or figure our interesting things to use ourselves for.”

“Individual human beings are all tools, that the others use to help us all survive.” “That’s a lie.” “No. It’s just a half truth. You can worry about the other half after we win this war.”

“Since we are not yet fully comfortable with the idea that people from the next village are as human as ourselves, it is presumptuous in the extreme to suppose we could ever look at sociable, tool-making creatures who arose from other evolutionary paths and see not beasts but brothers, not rivals by fellow pilgrims journeying to the shrine of intelligence. Yet that is what I see, or yearn to see. The difference between raman and varelse is not in the creature judged but in the creature judging, and when we declare an alien species to be raman, it does not mean that they have passed a threshold of moral maturity. It means that we have.”

“Do you know why Satan is so angry all the time? Because whenever he works a particularly clever bit of mischief God uses it to serve his own Rigteous purposes.""So God uses wicked people as his tools?""God gives us the freedom to to do great evil, if we choose, then He uses his own freedom to create goodness out of that evil, for that is what He chooses.""So, in the long run, God always wins?""Yes, in the short run though it can be uncomfortable.”

“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.”

“I understand that you believe that it works,' said Thrower patiently. 'But everything in the world is either science or miracles. Miracles came from God in the ancient times, but those times are over. Today if we wish to change the world, it isn't magic but science that will give us our tools.”

“Life is full of grief, to exactly the degree we allow ourselves to love other people.”
