Living among such men, who are so confused so ignorant of what they say, and of evils which they have or have not, and why they have them, or how they shall be relieved of them, I think it is worth the trouble for a man to watch constantly "Whether I also am one of them, what imagination I have about myself, how I conduct myself, whether I conduct myself as a prudent man, whether I conduct myself as a temperate man, whether I ever say this, that I have been taught to be prepared for everything that may happen. Have I the consciousness, which a man who knows nothing ought to have, that I know nothing? Do I go to my teacher as men go to oracles, prepared to obey? or do I like a sniveling boy go to my school to learn history and understand the books which I did not understand before, and, if it should happen so, to explain them also to others?" Man, you have had a fight in the house with a poor slave, you have turned the family upside down, you have frightened the neighbours, and you come to me as if you were a wise man, and you take your seat and judge how I have explained some word, and how I have babbled whatever came into my head. You come full of envy, and humbled, because you bring nothing from home; and you sit during, the discussion thinking of nothing else than how your father is disposed toward you and your brother. "What are they saying about me there? now they think that I am improving, and are saying, 'He will return with all knowledge.' I wish I could learn everything before I return: but much labour is necessary, and no one sends me anything, and the baths at Nicopolis are dirty; everything is bad at home, and bad here."
Then they say, "No one gains any profit from the school." Why, who comes to the school, who comes for the purpose of being improved? who comes to present his opinions to he purified? who comes to learn what he is in want of? Why do you wonder then if you carry back from the school the very things which you bring into it? For you come not to lay aside or to correct them or to receive other principles in place of them. By no means, nor anything like it. You rather look to this, whether you possess already that for which you come. You wish to prattle about theorems? What then? Do you not become greater triflers? Do not your little theorems give you some opportunity of display? You solve sophistical syllogisms. Do you not examine the assumptions of the syllogism named "The Liar"? Do you not examine hypothetical syllogisms? Why, then, are you still vexed if you receive the things for which you come to the school? "Yes; but if my child die or my brother, or if I must die or be racked, what good will these things do me?" Well, did you come for this? for this do you sit by my side? did you ever for this light your lamp or keep awake? or, when you went out to the walking-place, did you ever propose any appearance that had been presented to you instead of a syllogism, and did you and your friends discuss it together? Where and when? Then you say, "Theorems are useless." To whom? To such as make a bad use of them. For eyesalves are not useless to those who use them as they ought and when they ought. Fomentations are not useless. Dumb-bells are not useless; but they are useless to some, useful to others. If you ask me now if syllogisms are useful, I will tell you that they are useful, and if you choose, I will prove it. "How then will they in any way be useful to me?" Man, did you ask if they are useful to you, or did you ask generally? Let him who is suffering from dysentery ask me if vinegar is useful: I will say that it is useful. "Will it then be useful to me?" I will say, "No." Seek first for the discharge to be stopped and the ulcers to be closed. And do you, O men, first cure the ulcers and stop the discharge; be tranquil in your mind, bring it free from distraction into the school, and you will know what power reason has.
