Primitive men were quite content if they could escape being injured by strange and fierce animals, and this was the aim and end of their struggles against the wild beasts; but their successors, by learning, as they did, how to make use of them, now profit by them through using their flesh for food, their hair for clothing, their gall and colostrum as medicine, and their skins as armour, so that there is good reason to fear that, if the supply of wild beasts should fail man, his life would become bestial, helpless, and uncivilized. Cf. Moralia 964 A. Since, then, it is enough for most people if they can avoid suffering ill-treatment at the hands of their enemies, and since Xenophon Oeconomicus 1.15; cf. also Cyropaedia , i. 6. 11. asserts that men of sense will even derive profit from those who are at variance with them, we must not refuse him credence, but rather try to discover the system and the art through which this admirable advantage is to be gained by those who find it impossible to live without an enemy. The farmer cannot domesticate every tree, nor can the huntsman tame every beast; and so they have sought to derive profit from these in ways to meet their other needs: the farmer from the trees that bear no fruit and the huntsman from the Wild animals. The water of the sea is unfit to drink and tastes vile; yet fish thrive in it, and it is a medium for the dispatch and conveyance of travellers everywhere. The Satyr, at his first sight of fire, wished to kiss and embrace it, but Prometheus said, You, goat, will mourn your vanished beard, From Prometheus the Fire-bearer of Aeschylus. Cf. Nauck, Trag. Graec. Frag., Aeschylus, No. 207. for fire burns him who touches it, yet it furnishes light and heat, and is an instrument of every craft for those who have learned to use it. So look at your enemy, and see whether, in spite of his being in most respects harmful and difficult to manage, he does not in some way or other afford you means of getting hold of him and of using him as you can use no one else, and so can be of profit to you. Many of the circumstances of life are unkindly and hateful and repellent to those who have to meet them; yet you observe that some have employed their attacks of bodily illness for quiet resting, and trials which have fallen to the lot of many have but strengthened and trained them. Some, too, have made banishment and loss of property a means of leisure and philosophic study, as did Diogenes Cf. Diogenes Laertius, vi. 20 ff. and Crates. Ibid. vi. 85. And Zeno, The remark of Zeno is again referred to by Plutarch in Moralia , 467 D and 603 D: cf. also Diogenes Laertius, vii. 5, and Seneca, De animi tranquillitate, chap. xiii. on learning that the ship which bore his venture had been wrecked, exclaimed, A real kindness, O Fortune, that thou, too, dost join in driving us to the philosopher’s cloak ! For just as those animals which have the strongest and soundest stomachs can eat and digest snakes and scorpions, and there are some even that derive nourishment from stones and shells (for they transmute such things by reason of the vigour and heat of their spirit), while fastidious and sickly persons are nauseated if they partake of bread and wine, so fools spoil even their friendships, while wise men are able to make a fitting use even of their enmities. In the first place, then, it seems to me that the most harmful element in enmity may be made most profitable to those who give heed. What is this ? Your enemy, wide awake, is constantly lying in wait to take advantage of your actions, and seeking to gain some hold on you, keeping up a constant patrol about your life; and not only does his sight, like the sight of Lynceus, Lynceus was gifted with superhuman powers of vision; cf. for example Moralia , 1083 D; Pindar, Nemean Odes , x. 60; Horace, Epistles , i. 1. 28, and Pausanias, iv. 2. penetrate the oak-tree and stones and tiles, but your enemy, through every friend and servant and acquaintance as well, so far as possible, plays the detective on your actions and digs his way into your plans and searches them through and through. Oftentimes we do not learn, until too late, of the illness or the death of our friends, so careless are we and neglectful; but our curiosity about our enemies all but prompts us to pry into their dreams; sickness, debts, and conjugal disagreements are more likely to be unknown to the very persons affected than to their enemy. Especially does he try to get hold of their failings and ferret them out. And just as vultures are drawn to the smell of decomposed bodies, but have no power to discover those that are clean and healthy, so the infirmities, meannesses, and untoward experiences of life rouse the energies of the enemy, and it is such things as these that the malevolent pounce upon and seize and tear to pieces. Is this then profitable ? Assuredly it is, to have to live circumspectly, to give heed to one’s self, and not to do or say anything carelessly or inconsiderately, but always to keep one’s life unassailable as though under an exact regimen. For the circumspection which thus represses the emotions and keeps the reasoning power within bounds gives practice and purpose in living a life that is fair and free from reproach. For just as states which are chastened by border warfare and continual campaigning become well content with good order and a sound government, so persons who have been compelled on account of enmities to practise soberness of living, to guard against indolence and contemptuousness, and to let some good purpose prompt each act, are insensibly led by force of habit to make no mistakes, and are made orderly in their behaviour, even if reason co-operate but slightly. For when men keep always ready in mind the thought that Priam and Priam’s sons would in truth have cause for rejoicing, Homer, Il. i. 255. The words are addressed by Nestor to the Greek leaders, Agamemnon and Achilles, who have quarrelled. it causes them to face about and turn aside and abandon such things as give their enemies occasion for rejoicing and derision. Furthermore, we observe that the Dionysiac artists Actors and musicians. often play their parts in the theatres in a listless, dispirited, and inaccurate way when they are by themselves; but when there is rivalry and competition with another company, then they apply not only themselves but their instruments more attentively, picking their strings and tuning them and playing their flutes in more exact harmony. So the man who knows that his enemy is his competitor in life and repute is more heedful of himself, and more circumspect about his actions, and brings his life into a more thorough harmony. For it is a peculiar mark of vice, that we feel more ashamed of our faults before our enemies than before our friends. This is the ground of Nasica’s remark, when some expressed their belief that the power of the Romans was now secure, inasmuch as the Carthaginians had been annihilated and the Achaeans reduced to subjection. Nay, he said, now is our position really dangerous, since we have left for ourselves none to make us either afraid or ashamed.
