It follows, in the next place, that we should speak of temperance, and show how it was cultivated by Pythagoras, and how he delivered it to his associates. We have already therefore narrated the common precepts concerning it, in which it is said that every thing incommensurate should be cut off with fire and sword. The abstinence also from animal food, is a precept of the same species; and likewise from certain foods calculated to produce intemperance, and impeding the vigilance and genuine energies of the reasoning power. Farther still, to this species the precept belongs, that sumptuous food should indeed be introduced in banquets, but should [shortly after] be sent away, and given to the servants, being placed on the table merely for the sake of punishing the desires. Likewise, that no liberal and ingenuous woman should wear gold, but only harlots. And again, the exercise of taciturnity, and perfect silence, for the purpose of governing the tongue. Likewise a strenuous and assiduous resumption and investigation of the most difficult theorems. But on account of all these, we must refer to the same virtue [i. e. to temperance,] abstinence from wine; paucity of food and sleep; an inartificial contempt of renown, wealth, and the like; a sincere reverence towards those to whom reverence is due, but an unfeigned similitude of behaviour and benevolence towards those of the same age; an animadversion and exhortation of those that are younger, without envy; and every thing else of the like kind.
