My father, to whom I owe so much, never told me the difference between right and wrong; now I think that's why I remain so greatly in his debt.

Human beings are perhaps never more frightening than when they are convinced beyond doubt that they are right.

The need to be right - the sign of a vulgar mind.

Some people are worried about the difference between right and wrong. I'm worried about the difference between wrong and fun.

If you're going to do something wrong, at least enjoy it.

H. L. Mencken told me once that he answered all his mail, pleasant and unpleasant, with just one line, 'You may be right.' That's the way I feel now. It is in the realm of possibility, just barely, that I could be the one who's wrong.

You had to be a crank to insist on being right.

Distinction between virtuous and vicious actions has been engraven by the Lord in the heart of every man.

I leave this rule for others when I'm dead, Be always sure you are right-then go ahead.
