A clever person solves a problem. A wise person avoids it.

Try to become not a man of success, but try rather to become a man of value.

The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it.

Computers are incredibly fast, accurate and stupid. Human beings are incredibly slow, inaccurate and brilliant. Together they are powerful beyond imagination.

Sometimes I wonder whether the world is being run by smart people who are putting us on, or by imbeciles who really mean it.

I've never killed a man, but I've read many an obituary with a great deal of satisfaction.

We are what we pretend to be, so we must be careful what we pretend to be.

The loud little handful will shout for war. The pulpit will warily and cautiously protest at first…The great mass of the nation will rub its sleepy eyes, and will try to make out why there should be a war, and they will say earnestly and indignantly: "It is unjust and dishonorable and there is no need for war." Then the few will shout even louder…Before long you will see a curious thing: anti-war speakers will be stoned from the platform, and free speech will be strangled by hordes of furious men who still agree with the speakers but dare not admit it ... Next, statesmen will invent cheap lies, putting blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception.

Only a life lived for others is a life worthwhile.

A purpose of human life, no matter who is controlling it, is to love whoever is around to be loved.
