Plato, Protagoras

[328a] you would find none anywhere; and I suppose you might ask, who can teach the sons of our artisans the very crafts which of course they have learnt from their fathers, as far as the father was competent in each case, and his friends who followed the same trade,—I say if you asked who is to give these further instruction, I imagine it would be hard, Socrates, to find them a teacher, but easy enough in the case of those starting with no skill at all. And so it must be with virtue and everything else; if there is somebody who excels us ever so little [328b] in showing the way to virtue, we must be thankful. Such an one I take myself to be, excelling all other men in the gift of assisting people to become good and true, and giving full value for the fee that I charge—nay, so much more than full, that the learner himself admits it. For this reason I have arranged my charges on a particular plan: when anyone has had lessons from me, if he likes he pays the sum that I ask; if not, [328c] he goes to a temple, states on oath the value he sets on what he has learnt, and disburses that amount. So now, Socrates, I have shown you by both fable and argument that virtue is teachable and is so deemed by the Athenians, and that it is no wonder that bad sons are born of good fathers and good of bad, since even the sons of Polycleitus, companions of Paralus and Xanthippus here, are not to be compared with their father, and the same is the case in other craftsmen's families. As for these two, it is not fair to make this complaint of them yet; [328d] there is still hope in their case, for they are young.

After this great and fine performance Protagoras ceased from speaking. As for me, for a good while I was still under his spell and kept on looking at him as though he were going to say more, such was my eagerness to hear: but when I perceived that he had really come to a stop, I pulled myself together, as it were, with an effort, and looking at Hippocrates I said: Son of Apollodorus, I am very grateful to you for inducing me to come hither; [328e] for it is a great treat to have heard what I have heard from Protagoras. I used formerly to think that there was no human treatment by which the good were made good, but now I am convinced that there is. Only I find one slight difficulty, which Protagoras will of course easily explain away, since he has explained so many puzzles already. If one should be present when any of the public speakers were dealing with
