“A prudent man concealeth knowledge: But the heart of fools proclaimeth foolishness”
Proverbs 12:23
Another way of saying this is that a prudent man holds back, while a foolish man empties whatever box it is that he has. A prudent man has knowledge, but he doesn’t let us see all of it. A foolish man has a bunch of nothing, and he spreads it out all over the table for us.
