Brothers should not be like the scales of a balance, the one rising upon the other’s sinking; but rather like numbers in arithmetic, the lesser and greater mutually helping and improving each other. For that finger which is not active in writing or touching musical instruments is not inferior to those that can do both; but they all move and act, one as well as another, and are assistant to each other, which makes the inequality among them seem designed by Nature, when the greatest cannot be without the help of the least that is placed in opposition to it. Thus Craterus and Perilaus, brothers to kings Antigonus and Cassander, betook themselves, the one to managing of military, the other of his domestic affairs. On the other hand, the men like Antiochus, Seleucus, Grypus, and Cyzicenus, disdaining any meaner things than purple and diadems, brought a great deal of trouble and mischief upon one another, and made Greece itself miserable with their quarrels. But in regard that men of ambitious inclinations will be apt to envy those who have got the start of them in honor, I judge it most convenient for brothers to take different methods in pursuit of it, rather than to vex and emulate one another in the same way. Those beasts fight and war one with another who feed in one pasture, and wrestlers are antagonists when they strive in the same game. But those that pretend to different games are the greatest friends, and ready to take one another’s parts with the utmost of their skill and power. So the two sons of Tyndarus, Castor and Pollux, carried the day,—Pollux at cuffs, and Castor at racing. Thus Homer brings in Teucer as expert in the bow, whom his brother Ajax, who was best in close fight, Protected over with a glittering shield.. VIII. 272.

And amongst those who are concerned in the Common wealth a general of an army does not much envy the leaders of the people, nor among those that profess rhetoric do the lawyers envy the sophisters, nor amongst the physicians do those who prescribe rules for diet envy the chirurgeon; but they mutually aid and assert the credit of one another. But for brothers to study to be eminent in the same art and faculty is all the same, amongst ill men, as if rival lovers, courting one and the same mistress, should both strive to gain the greatest interest in her affections. Those indeed that travel different ways can probably do one another but little good; but those who carry on quite different designs, and take several methods in their conversations, avoid envy, and many times do one another a kindness. As Demosthenes and Chares, and again Aeschines and Eubulus, Hyperides and Leosthenes, the one treating the people with their discourses and writings, the others assisting them by action and conduct. Therefore, where the disposition of brothers is such that they cannot agree in prosecuting the same methods of becoming great, it is convenient that one of them should so command himself as to assume the most different inclinations and designs from his brother; that, if they both aim at honor, they may serve their ambition by different means, and that they may cheerfully congratulate each other on the success of their designs, and so enjoy at once their honor and them selves.
