A wise man understands, an intelligent man knows, but a fool pretends to know.

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

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

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

Love is the power of a wise man. It is a net for a lover. It is a tool for a clever man. Love is a song for a singer.

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