There was once a small town, with only a few inhabitants; a mighty king made war on it, laying siege to it and building great siege-works round it.  But there was in that town a poverty-stricken sage who by his wisdom saved the town. No one remembered this poor man afterwards.  So I say: Wisdom is more effective than brute force, but the wisdom of a poor man is not valued: no one listens to what he has to say.  The calm words of the wise make themselves heard above the shouts of someone commanding an army of fools.  Wisdom is worth more than weapons of war, but a single sin undoes a deal of good. — (Eccl. 9:14-18)
