By this practice we shall be brought at length to perform the most honorable and worthy actions; for he who is wont to praise and speak the best things of his enemies will never repine at the prosperity or success of his friends and acquaintance; he is never troubled, but rather rejoices, when they thrive and are happy. And what virtue can any man exercise that will be more profitable and delightful to him than this, which takes away from him the bitterness of malice, and doth not only break the teeth of envy, but, by teaching him to rejoice at another man’s felicity, doth double his own enjoyment and satisfaction. As in war many things, although they are bad and evil in themselves, yet have become necessary, and by long custom and prescription have obtained the validity of a law, so that it is not easy to root them out, even by those who thereby suffer much harm; just so doth enmity usher in the mind a long train of vices, meagre envy coupled with grim hatred, restless jealousy and suspicion, unnatural joy at other men’s miseries, and a long remembrance of injuries. Fraud, deceit, and snares, joined to these forces of wickedness, work infinite mischief in the world, yet they appear as no evils at all when they are exerted against an enemy. By this means they make a deep entrance into the mind; they get fast hold of it, and are hardly shaken off. So that, unless we forbear the practice of these ill qualities towards our enemies, they will by frequent acts become so habitual to us, that we shall be apt to make use of them to the manifest wrong and injury of our friends. Wherefore, if Pythagoras was highly esteemed for instructing his disciples to avoid all manner of cruelty against beasts themselves,—so that he himself would redeem them out of their captivity in either the fowler’s or the fisherman’s net, and forbade his followers to kill any creature,—it is surely much better and more manly in our differences with men to show ourselves generous, just, and detesters of all falsehood, and to moderate and correct all base, unworthy, and hurtful passions; that in all our conversation with our friends we may be open-hearted, and that we may not seek to overreach or deceive others in any of our dealings.
