232
Str. And did we not also say that he taught this same art of disputing to others?
232
Theaet. Certainly.
232
Str. Now let us examine and see what the subjects are about which such men say they make their pupils able to dispute. Let us begin our examination at the beginning with this question: Is it about divine things which are invisible to others that they make people able to dispute?
232
Theaet. That is their reputation, at any rate.
232
Str. And how about the visible things of earth and heaven and the like?
232
Theaet. Those are included, of course.
232
Str. And furthermore in private conversations, when the talk is about generation and being in general, we know (do we not?) that they are clever disputants themselves and impart equal ability to others.
232
Theaet. Certainly.
232
Str. And how about laws and public affairs in general? Do they not promise to make men able to argue about those?
232
Theaet. Yes, for nobody, to speak broadly, would attend their classes if they did not make that promise.
232
Str. However in all arts jointly and severally what the professional ought to answer to every opponent is written down somewhere and published that he who will may learn.
232
Theaet. You seem to refer to the text-books of Protagoras on wrestling and the other arts.
232
Str. Yes, my friend, and to those of many other authors. But is not the art of disputation, in a word, a trained ability for arguing about all things?
232
Theaet. Well, at any rate, it does not seem to leave much out.
232
Str. For heaven’s sake, my boy, do you think that is possible? For perhaps you young people may look at the matter with sharper vision than our duller sight.
233
Theaet. What do you mean and just what do you refer to? I do not yet understand your question.
233
Str. I ask whether it is possible for a man to know all things.
233
Theaet. If that were possible, Stranger, ours would indeed be a blessed race.
233
Str. How, then, can one who is himself ignorant say anything worth while in arguing with one who knows?
233
Theaet. He cannot at all.
