SOC. And do you think his doctrine might stand most firmly in the form in which we sketched it when defending Protagoras, that most things—hot, dry, sweet, and everything of that sort—are to each person as they appear to him, and if Protagoras is to concede that there are cases in which one person excels another, he might be willing to say that in matters of health and disease not every woman or child—or beast, for that matter—knows what is wholesome for it and is able to cure itself, but in this point, if in any, one person excels another?

SOC. And likewise in affairs of state, the honorable and disgraceful, the just and unjust, the pious and its opposite, are in truth to each state such as it thinks they are and as it enacts into law for itself, and in these matters no citizen and no state is wiser than another; but in making laws that are advantageous to the state, or the reverse, Protagoras again will agree that one counsellor is better than another, and the opinion of one state better than that of another as regards the truth, and he would by no means dare to affirm that whatsoever laws a state makes in the belief that they will be advantageous to itself are perfectly sure to prove advantageous. But in the other class of things—I mean just and unjust, pious and impious—they are willing to say with confidence that no one of them possesses by nature an existence of its own; on the contrary, that the common opinion becomes true at the time when it is adopted and remains true as long as it is held; this is substantially the theory of those who do not altogether affirm the doctrine of Protagoras. But, Theodorus, argument after argument, a greater one after a lesser, is overtaking us.

THEO. Well, Socrates, we have plenty of leisure, have we not?
