As for the argument that, if each man is the measure of all things, one man is as wise as another, Socrates suggests, on behalf of Protagoras, a very interesting answer, namely that, while one judgement cannot be truer than another, it can be better, in the sense of having better consequences. This suggests pragmatism. It is presumably this passage that first suggested to F.C.S. Schiller his admiration of Protagoras. He urges, for example, that when a doctor foretells the course of my illness, he actually knows more of my future than I do. And when men differ as to what is wise for the State to decree, the issue shows that some men had a greater knowledge as to the future than others had. Thus we cannot escape the conclusion that a wise man is a better measure of things than a fool.p. 151.
