The more you learn, the more you know that you know nothing.

When you see that trading is done, not by consent, but by compulsion...th at in order to produce, you need to obtain permission from men who produce nothing-you may know that your society is doomed.

One loses everything when one loses one's sense of humor.

When you have made evil the means of survival, do not expect men to remain good. Do not expect them to stay moral and lose their lives for the purpose of becoming the fodder of the immoral. Do not expect them to produce, when production is punished and looting rewarded. Do not ask, "Who is destroying the world?" You are.
