Tricks and treachery are the practice of fools that don't have brains enough to be honest.
We are all fools when one wise man appears.
Orson Scott Card
Wise men talk because they have something to say fools, because they have to say something.

Prejudice is the reason of fools.
Those who are not angry at the things they should be angry at are thought to be fools, and so are those who are not angry in the right way, at the right time, or with the right persons.
Wise men speak because they have something to say; Fools because they have to say something.
