Proverbs 26:4-5 make a revealing couplet. They contradict each other, and for good reason. There is no good way to deal with a fool. If you answer him according to his folly, you will be seen to be a fool, like him. On the other hand, if you answer a fool according to his folly, he will think himself wise, like yourself. It is impossible to reason with a fool. They are convinced in their own mind. Proverbs exhorts people to get away from fools (Prov 14:7).
