I am a fool, but I know I'm a fool and that makes me smarter than you.

Never argue with a fool, onlookers may not be able to tell the difference.

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

The foolish man conceives the idea of 'self.' The wise man sees there is no ground on which to build the idea of 'self;' thus, he has a right conception of the world and well concludes that all compounds amassed by sorrow will be dissolved again, but the truth will remain.

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

Every fool believes what his teachers tell him, and calls his credulity science or morality as confidently as his father called it divine revelation.
