With respect to justice, however, we shall learn in the best manner, how he cultivated and delivered it to mankind, if we survey it from its first principle, and from what first causes it germinates, and also direct our attention to the first cause of injustice. For thus we shall discover how he avoided the latter, and what methods he adopted in order that the former might be properly ingenerated in the soul. The principle of justice therefore, is the common and the equal, through which, in a way most nearly approximating to one body and one soul, all men may be co-passive, and may call the same thing mine and thine; as is also testified by Plato, who learnt this from the Pythagoreans. This therefore, Pythagoras effected in the best manner, exterminating every thing private in manners, but increasing that which is common as far as to ultimate possessions, which are the causes of sedition and tumult. For all things [with his disciples] were common and the same to all, and no one possessed any thing private. And he indeed, who approved of this communion, used common possessions in the most just manner; but he who did not, received his own property, which he brought to the common stock, with an addition to it, and departed. And thus he established justice in the best manner, from the first principle of it. In the next place, therefore, association with men introduces justice; but alienation, and a contempt of the common genus, produce injustice. Wishing therefore to insert this familiarity from afar in men, he also ordained that his disciples should extend it to animals of the same genus, and commanded them to consider these as their familiars and friends; so as neither to injure, nor slay, nor eat any one of them. He therefore who associates men with animals, because they consist of the same elements as we do, and participate with us of a more common life, will in a much greater degree establish fellowship with those who partake of a soul of the same species, and also of a rational soul. From this also it is evident that he introduced justice produced from the most proper principle. Since likewise the want of riches, sometimes compels many to do something contrary to justice, he well foresaw that this would be the case, and through economy procured for himself liberal expenses, and what was just in sufficient abundance. For again, a just arrangement of domestic concerns is the principle of all good order in cities. For cities are constituted from houses. It is said therefore, that Pythagoras himself was the heir of the property of Alcæus, who died after performing an embassy to the Lacedæmonians, but that notwithstanding this, he was no less admired for his economy than for his philosophy. When also he was married, he so educated the daughter that was born to him, and who was afterwards married to Meno the Crotonian, that when she was a virgin she was the leader of choirs, but when a wife she held the first place among those that approached to
