Fools call wise men fools. A wise man never calls any man a fool.

The tongue of a fool is the key of his counsel, which, in a wise man, wisdom hath in keeping.

Men are wise in proportion, not to their experience, but to their capacity for experience.

The man who is truly wise knows that he knows very little.

What the wise do in the beginning, fools do in the end.

Speak only if it improves upon the silence.
