All men agree that a just distribution must be according to merit in some sense; they do not all specify the same sort of merit, but democrats identify it with freemen, supporters of oligarchy with wealth (or noble birth), and supporters of aristocracy with excellence.
The truth of an upright man must be accepted on his own terms. Moreover, since natures vary, we must agree that all the beauties of human excellence may be fostered by faiths that we do not share.
