There are a lot of intelligent fools, but no wise idiots.

A statement using the words always and never is never always 100% accurate.

He was a good man, but too good a man to be a great man.

A man who would give advice without understanding is a fool.

Idiots are of two kinds: those who try to be smart and those who think they are smart.

What sets humans apart from animals is that we have to walk around saying how smart we are, and animals just live their lives.
