18. Like a house in ruins is wisdom to a fool;to the stupid, knowledge is incomprehensible chatter.
19. To the senseless, education is fetters on the feet,like manacles on the right hand.
20. Fools raise their voice in laughter,but the prudent at most smile quietly.
21. Like a gold ornament is education to the wise,like a bracelet on the right arm.
22. A fool steps boldly into a house,while the well-bred are slow to make an entrance.
23. A boor peeps through the doorway of a house,but the educated stay outside.
