The pursuit of good ends does not justify the employment of bad means. The only people who can hold up indefinitely under the stress of modern war are psychotics. You can't consume much if you sit still and read books. You can't have a lasting civilisation without plenty of pleasant vices. You can't teach a rhinoceros tricks.
Some men are almost rhinoceroses.
Without freedom, human beings cannot become fully human. When the individual feels, the community reels. What fun it would be if one didn't have to think about happiness. When people are suspicious with you, you start being suspicious with them. We must learn to simplify, but not to the point of falsification.
