“Now, there's this about cynicism, Sergeant. It's the universe's most supine moral position. Real comfortable. If nothing can be done, then you're not some kind of shit for not doing it, and you can lie there and stink to yourself in perfect peace.”

“Do it for yourself. The universe will be around to collect its cut later.”

“Never do yourself, what you can con professionals into doing for you.”

“War is not its own end, except in some catastrophic slide into absolute damnation. It's peace that's wanted. Some better peace than the one you started with.”

“This is the most important thing I will ever say to you. The human mind is the ultimate testing device. You can take all the notes you want on the technical data, anything you forget you can look up again, but this must be engraved on your hearts in letters of fire. There is nothing, nothing, nothing, more important to me in the men and women I train than their absolute personal integrity. Whether you function as welders or inspectors, the laws of physics are implacable lie detectors. You may fool men. You will never fool metal. That’s all.”

“Any man can be kind when he is comfortable. I'd always thought kindness a trivial virtue, therefore. But when we were hungry, thirsty, sick, frightened, with our deaths shouting at us, in the heart of horror, you were still as unfailingly courteous as a gentleman at ease before his own hearth.”

“If you can't do what you want, do what you can.”
