THAT WE OUGHT WITH CAUTION TO ENTER INTO FAMILIAR INTERCOURSE WITH MEN.—If a man has frequent intercourse with others either for talk, or drinking together, or generally for social purposes, he must either become like them, or change them to his own fashion. For if a man places a piece of quenched charcoal close to a piece that is burning, either the quenched charcoal will quench the other, or the burning charcoal will light that which is quenched. Since then the danger is so great, we must cautiously enter into such intimacies with those of the common sort, and remember that it is impossible that a man can keep company with one who is covered with soot without being partaker of the soot himself. For what will you do if a man speaks about gladiators, about horses, about athletes, or what is worse about men? Such a person is bad, such a person is good; this was well done, this was done badly. Further, if he scoff, or ridicule, or show an ill-natured disposition? Is any man among us prepared like a lute-player when he takes a lute, so that as soon as he has touched the strings, he discovers which are discordant, and tunes the instrument? Such a power as Socrates had who in all his social intercourse could lead his companions to his own purpose? How should you have this power? It is therefore a necessary consequence that you are carried about by the common kind of people. Why then are they more powerful than you? Because they utter these useless words from their real opinions; but you utter your elegant words only from your lips; for this reason they are without strength and dead, and it is nauseous to listen to your exhortations and your miserable virtue, which is talked of everywhere (up and down). In this way the vulgar have the advantage over you; for every opinion ([Greek: dogma]) is strong and invincible. Until then the good ([Greek: chompsai]) sentiments ([Greek: hupolaepseis]) are fixed in you, and you shall have acquired a certain power for your security, I advise you to be careful in your association with common persons; if you are not, every day like wax in the sun there will be melted away whatever you inscribe on your minds in the school. Withdraw then yourselves far from the sun so long as you have these waxen sentiments. For this reason also philosophers advise men to leave their native country, because ancient habits distract them and do not allow a beginning to be made of a different habit; nor can we tolerate those who meet us and say: See such a one is now a philosopher, who was once so and so. Thus also physicians send those who have lingering diseases to a different country and a different air; and they do right. Do you also introduce other habits than those which you have; fix you opinions and exercise yourselves in them. But you do not so; you go hence to a spectacle, to a show of gladiators, to a place of exercise ([Greek: chuston]), to a circus; then you come back hither, and again from this place you go to
