many a man before now who has sought a righteous revenge, far from obtaining it, has not even escaped himself; and many an one who in the consciousness of power has grasped at what was another’s, has ended by losing what was his own. The revenge of a wrong is not always successful merely because it is just; nor is strength most assured of victory when it is most full of hope. The inscrutable future is the controller of events, and, being the most treacherous of all things, is also the most beneficent; for when there is mutual fear, men think twice before they make aggressions upon one another.
