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

Better a witty fool, than a foolish wit.

Do not keep company with a fool for as we can see he is a two-legged beast. Like an unseen thorn he pierces the heart with his sharp words.

First love is only a little foolishness and a lot of curiosity.

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

A fool's brain digests philosophy into folly, science into superstition, and art into pedantry. Hence University education.
