Hippocrates, a young Athenian, had roused Socrates very early in the morning and entreated him to accompany him on a visit to Protagoras, who was then at Athens staying at the house of Callias, and whose pupil he was anxious to become. On arriving there, they find the sophist attended by a crowd of admirers, and moreover Hippias of Elis and Prodicus of Ceos, surrounded by their respective followers[87]. ----- Footnote 87: § 1-18. ----- After Socrates had made known the object of his visit to Protagoras, Callias proposes that the whole party should sit down and listen to the conversation. When all are seated, Socrates repeats to Protagoras, that Hippocrates is desirous of becoming his pupil, and wishes to know what advantage he may expect to derive from associating with him. Protagoras tells him that from the very first day of their intercourse he will become a better man than he was before, and will daily make further progress. But, asks Socrates, in what will he become better, and in what make further progress? In the management of his domestic and public affairs, that is to say, in the political art. To this Socrates objects that the general opinion is that political virtue cannot be taught, and that, whereas with respect to arts and sciences it was usual only to consult persons who had made them their study and were skilled in them, in affairs of state every one, of whatever condition, was at liberty to give his opinion; he therefore begs Protagoras to prove that virtue can be taught[88]. To this end Protagoras relates a fable in which he explains how the capacity of becoming virtuous was imparted by Jupiter to mankind; and then argues that as men are punished for injustice, impiety, and the like, it follows that they must think that these virtues ought to be possessed and may be acquired by all men, for that they would not punish them for a mere defect of mind any more than of body, if it were natural and not attributable to the fault of the individual[89]. ----- Footnote 88: § 19-29. ----- Socrates having complimented him on his eloquence, according to his usual method, begs that he will answer his questions briefly; and then expresses his surprise at having heard Protagoras speak of justice, temperance, holiness, and the like, as if they were collectively virtue. He therefore wishes to know whether virtue is one thing, and justice, temperance and holiness, parts of it, or whether they are all names of one and the same thing. Protagoras answers that virtue is one thing, and these several qualities parts of it. Are they then parts like the parts of a face, the mouth, nose, eyes, and ears, or like the parts of gold, which do not differ from each other? Like the former. In that case holiness and justice must be different from each other, which, as Protagoras is at length compelled, though unwillingly, to admit, is absurd[90].
