text: You must, however, reflect thus what danger you run at the hands of man, in order that you may deduce what is the duty of man. Try, in your dealings with others, to harm not, in order that you be not harmed. You should rejoice with all in their joys and sympathize with them in their troubles, remembering what you should offer and what you should withhold. And what may you attain by living such a life? Not necessarily freedom from harm at their hands, but at least freedom from deceit. In so far, however, as you are able, take refuge with philosophy: she will cherish you in her bosom, and in her sanctuary you shall be safe, or, at any rate, safer than before. People collide only when they are travelling the same path. But this very philosophy must never be vaunted by you; for philosophy when employed with insolence and arrogance has been perilous to many. Let her strip off your faults, rather than assist you to decry the faults of others. Let her not hold aloof from the customs of mankind, nor make it her business to condemn whatever she herself does not do. A man may be wise without parade and without arousing enmity. Farewell.
