EPICTETUS. DISCOURSES. Book ii. §24. ¶2.IF you have an earnest desire of attaining to philosophy, prepare yourself from the very first to be laughed at, to be sneered by the multitude, to hear them say, "He is returned to us a philosopher all at once," and "Whence this supercilious look?" Now, for your part, do not have a supercilious look indeed; but keep steadily to those things which appear best to you as one appointed by God to this station. For remember that, if you adhere to the same point, those very persons who at first ridiculed will afterwards admire you. But if you are conquered by them, you will incur a double ridicule.
