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

The man who remains a fool even in advanced age is really a fool, just as the Indra-Varuna fruit does not become sweet no matter how ripe it might become.

I've never fooled anyone. I've let people fool themselves. They didn't bother to find out who and what I was. Instead they would invent a character for me. I wouldn't argue with them. They were obviously loving somebody I wasn't.

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.

There is small disproportion betwixt a fool who useth not wit because he hath it not and him that useth it not when it should avail him.

A fool too late bewares when all the peril is past.
