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

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.

The fool has one great advantage over a man of sense; he is always satisfied with himself.

Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius -- and a lot of courage -- to move in the opposite direction.

The right combination of guilt and machismo has sent many a fool out into the jungle when he should have stayed home.

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.
