What things a man must learn in order to be able to apply the art of disputation, has been accurately shown by our philosophers; but with respect to the proper use of the things, we are entirely without practice. Only give to any of us, whom you please, an illiterate man to discuss with,, and he cannot discover how to deal with the man. But when he has moved the man a little, if he answers beside the purpose, he does not know how to treat him, but he then either abuses or ridicules him, and says, “He is an illiterate man; it is not possible to do anything with him.” Now a guide, when he has found a man out of the road leads him into the right way: he does not ridicule or abuse him and then leave him. Do you also show this illiterate man the truth, and you will see that he follows. But so long as you do not show him the truth, do not ridicule him, but rather feel your own incapacity.

How then did Socrates act? He used to compel his adversary in disputation to bear testimony to him, and he wanted no other witness. Therefore he could say, “I care not for other witnesses, but I am always satisfied with the evidence of my adversary, and I do not ask the opinion of others, but only the opinion of him who is disputing with me.” For he used to make the conclusions drawn from natural notions so plain that every man saw the contradiction and withdrew from it: “Does the envious man rejoice?” “By no means, but he is rather pained.” Well, “Do you think that envy is pain over evils? and what envy is there of evils?” Therefore he made his adversary say that envy is pain over good things. “Well then, would any man envy those who are nothing to him?” “By no means.” Thus having completed the notion and distinctly fixed it he would go away without saying to his adversary, “Define to me envy”; and if the adversary had defined envy, he did not say, “You have defined it badly, for the terms of the definition do not correspond to the thing defined.” These are technical terms, and for this reason disagreeable and hardly intelligible to illiterate men, which terms we cannot lay aside. But that the illiterate man himself, who follows the appearances presented to him, should be able to concede anything or reject it, we can never by the use of these terms move him to do. Accordingly, being conscious of our own inability, we do not attempt the thing; at least such of us as have any caution do not. But the greater part and the rash, when they enter into such disputations, confuse themselves and confuse others; and final............
