The difference between a wise and foolish man is this--the former sees much, thinks much, and speaks little; but the latter speaks more than he either sees or thinks.
- William Scott Downey
Proverbs 17:28 (NLT) Even fools are thought wise when they keep silent; with their mouths shut, they seem intelligent.
Proverbs 18:2 (NLT) Fools have no interest in understanding; they only want to air their own opinions.
Proverbs 29:11 (NLT) Fools vent their anger, but the wise quietly hold it back.
