Don't talk a lot with fools, and don't go to the unintelligent. Be on guard against them so that you don't have trouble and don't get dirty when they shake themselves off. Stay away from them and you will find rest, and their senselessness won't make you weary.

A heart fixed on thoughtful understanding is like an engraved ornament on a smooth wall.
