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.
