Jerome : "The words of a wise man win favour, but a fool's lips devour him. "Foolishness, if it is happy in its rusticity, will know less evil. But now he wages war against wisdom, and whatever prudence he sees in a learned man, he does not take to be incited by enthusiasm. For a wise man speaks words of knowledge, words of thanks, which are of use to those that hear them, but the lips of a fool do not receive what is said, as it is said; on the contrary they try to trip up a wise man and make him similar to a fool. And in fact a wise man is taught when a foolish man speaks in his ear, and you could almost say that his words are lost in the deep swell. Therefore he is blessed, who speaks in the ear of a wise man. — Commentary on Ecclesiastes
