A fool flatters himself, a wise man flatters the fool.

A fool thinks himself to be wise, but a wise man knows himself to be a fool.

The fool doth think he is wise, but the wise man knows himself a fool.

A fool sees not the same tree that a wise man sees.

The wise man does at once what the fool does finally.

The heart of a fool is in his mouth, but the mouth of the wise man is in his heart
