We ought therefore to eschew the aimless and the unprofitable in the chain of our thoughts, still more all that is over-curious and ill-natured, and a man should accustom himself to think only of those things about which, if one were to ask on a sudden, What now in thy thoughts? thou couldest quite frankly answer at once, This or that; so that thine answer should immediately make manifest that all that is in thee is simple and kindly and worthy of a living being that is social and has no thought for pleasures or for the entire range of sensual images, or for any rivalry, envy, suspicion, or anything else, whereat thou wouldest blush to admit that thou hadst it in thy mind. For in truth such a man, one who no longer puts off being reckoned now, if never before, among the best, is in some sort a priest and minister of the Gods, putting to use also that which, enthroned within him, keeps the man unstained by pleasures, invulnerable to all pain, beyond the reach of any wrong, proof against all evil, a champion in the highest of championships—that of never being overthrown by any passion—dyed in grain with justice, welcoming with all his soul everything that befalls and is allotted him, and seldom, nor yet without a great and a general necessity, concerning himself with the words or deeds or thoughts of another. For it is only the things which relate to himself that he brings within the scope of his activities, and he never ceases to ponder over what is being spun for him as his share in the fabric of the Universe, and he sees to it that the former are worthy, and is assured that the latter is good. For the fate which is allotted to each man is swept along with him in the Universe as well as sweeps him along with it. And he bears in mind that all that is rational is akin, and that it is in man's nature to care for all men, and that we should not embrace the opinion of all, but of those alone who live in conscious agreement with Nature. But what sort of men they, whose life is not after this pattern, are at home and abroad, by night and in the day, in what vices they wallow and with whom—of this he is ever mindful. Consequently he takes no account of praise from such men, who in fact cannot even win their own approval.
