of it, and therefore did not employ themselves in an exercise of this kind. Such therefore were the precepts which were daily delivered to the disciples of Pythagoras, with respect to nutriment and their mode of living. CHAP. XXII. Another mode also of erudition is transmitted to us, which was effected through Pythagoric precepts, and sentences which extended to human life and human opinions; a few of which out of many I shall narrate. One of these therefore contains an exhortation to remove contention and strife from true friendship, and especially from all friendship, if possible. But if this is not possible, at least to expel it from paternal friendship, and universally from that which subsists with elders and benefactors. For to contend pervicaciously with such as these, anger or some other similar passion intervening, is not to preserve, [but destroy] the existing friendship. But they say it is necessary that the smallest lacerations and ulcerations should take place in friendships. And that this will be effected, if both the friends know how to yield and subdue their anger, and especially the younger of the two, and who belongs to some one of the above-mentioned orders. They likewise thought it necessary that the corrections and admonitions which they called _pædartases_, and which the elder employed towards the younger, should be made with much suavity of manners and great caution; and also that much solicitude and appropriation should be exhibited in admonitions. For thus the admonition will become decorous and beneficial. They likewise say that faith should never be separated from friendship, neither seriously nor in jest. For it is no longer easy for the existing friendship to remain in a sane condition, when falsehood once insinuates itself into the manners of those who assert themselves to be friends. And again they say, that friendship is not to be rejected on account of misfortune, or any other imbecility which happens to human life; but that the only laudable rejection of a friend and of friendship, is that which takes place through great and incurable vice. Such therefore was the form of correction with the Pythagoreans through sentences, and which extended to all the virtues, and to the whole of life. CHAP. XXIII.
