Never proclaim yourself a philosopher, nor make much talk among the ignorant about your principles, but show them by actions. Thus, at an entertainment, do not discourse how people ought to eat, but eat as you ought. For remember that thus Socrates also universally avoided all ostentation. And when persons came to him and desired to be introduced by him to philosophers, he took them and introduced them; so well did he bear being overlooked. So if ever there should be among the ignorant any discussion of principles, be for the most part silent. For there is great danger in hastily throwing out what is undigested. And if anyone tells you that you know nothing, and you are not nettled at it, then you may be sure that you have really entered on your work. For sheep do not hastily throw up the grass to show the shepherds how much they have eaten, but, inwardly digesting their food, they produce it outwardly in wool and milk. Thus, therefore, do you not make an exhibition before the ignorant of your principles, but of the actions to which their digestion gives rise. XLVII When you have learned to nourish your body frugally, do not pique yourself upon it; nor, if you drink water, be saying upon every occasion, “I drink water.” But first consider how much more frugal are the poor than we, and how much more patient of hardship. If at any time you would inure yourself by exercise to labor and privation, for your own sake and not for the public, do not attempt great feats; but when you are violently thirsty, just rinse your mouth with water, and tell nobody. XLVIII The condition and characteristic of a vulgar person is that he never looks for either help or harm from himself, but only from externals. The condition and characteristic of a philosopher is that he looks to himself for all help or harm. The marks of a proficient are that he censures no one, praises no one, blames no one, accuses no one; says nothing concerning himself as being anybody or knowing anything. When he is in any instance hindered or restrained, he accuses himself; and if he is praised, he smiles to himself at the person who praises him; and if he is censured, he makes no defense. But he goes about with the caution of a convalescent, careful of interference with anything that is doing well but not yet quite secure. He restrains desire; he transfers his aversion to those things only which thwart the proper use of our own will; he employs his energies moderately in all directions; if he appears stupid or ignorant, he does not care; and, in a word, he keeps watch over himself as over an enemy and one in ambush.
