And thus far, indeed, we have thought it requisite to mention this admirable and strenuous deed, the effect of his fortitude. We shall however adduce another example of it, viz. the salvation of legitimate opinion; for, preserving this, he performed that which appeared to him to be just, and which was dictated by right reason, not being diverted from his intention either by pleasure, or labor, or any other passion, or danger. His disciples also chose to die rather than transgress his mandates. And when they were exposed to all-various fortunes, they preserved invariably the same manners. When also they were involved in ten thousand calamities, they never deviated from his precepts. But it was a never-failing exhortation with them, always to give assistance to law, but to be hostile to illegality, and to be accustomed from their birth to a life of temperance and fortitude, in order to restrain and repel luxury. They had also certain melodies which were devised by them, as remedies against the passions of the soul, and likewise against despondency and lamentation, which Pythagoras invented, as affording the greatest assistance in these maladies. And again, they employed other melodies against rage and anger, through which they gave intension and remission to these passions, till they reduced them to moderation, and rendered them commensurate with fortitude. _That, however, which afforded them the greatest support in generous endurance, was the persuasion that no human casualties ought to be unexpected by men who are in the possession of intellect, but that all things ought to be expected by them, over which they have no absolute power._ Moreover, if at any time they happened to be angry, or sorrowful, they immediately separated themselves from the rest of their associates, and each by himself alone strenuously endeavoured to digest and heal the passion [by which he was oppressed]. They also conceived generally, that labor should be employed about disciplines and studies, and that they should be severely exercised in trials of the most various nature, in punishments and restraints by fire and sword, in order to be liberated from innate intemperance, and an inexhaustible avidity of possessing; and that for this purpose, no labors, nor any endurance should be spared. In order to accomplish this likewise, they generously exercised abstinence from all animals, and besides this, from certain other kinds of food. Hence also arose their detention of speech, and their perfect silence as preparatory to the subjugation of the tongue; in which for many years they exercised their fortitude. To which also may be added, their strenuous and assiduous investigation and resumption of the most difficult theorems; and on account of these things, their abstinence from wine, their paucity of food and sleep, and their contempt of glory, wealth, and the like. And in conjunction with all these particulars, they extended themselves to fortitude.
