Nay, Socrates, he replied, you are mistaken in your remembrance of what was said by me. When you asked me, I certainly did say that the courageous are the confident; but I was never asked whether the confident are the courageous; if you had asked me, I should have answered 'Not all of them': and what I did answer you have not proved to be false, although you proceeded to show that those who have knowledge are more courageous than they were before they had knowledge, and more courageous than others who have no knowledge, and were then led on to think that courage is the same as wisdom. But in this way of arguing you might come to imagine that strength is wisdom. You might begin by asking whether the strong are able, and I should say 'Yes'; and then whether those who know how to wrestle are not more able to wrestle than those who do not know how to wrestle, and more able after than before they had learned, and I should assent. And when I had admitted this, you might use my admissions in such a way as to prove that upon my view wisdom is strength; whereas in that case I should not have admitted, any more than in the other, that the able are strong, although I have admitted that the strong are able. For there is a difference between ability and strength; the former is given by knowledge as well as by madness or rage, but strength comes from nature and a healthy state of the body. And in like manner I say of confidence and courage, that they are not the same; and I argue that the courageous are confident, but not all the confident courageous. For confidence may be given to men by art, and also, like ability, by madness and rage; but courage comes to them from nature and the healthy state of the soul. I said: You would admit, Protagoras, that some men live well and others ill? He assented. And do you think that a man lives well who lives in pain and grief? He does not. But if he lives pleasantly to the end of his life, will he not in that case have lived well? He will. Then to live pleasantly is a good, and to live unpleasantly an evil? Yes, he said, if the pleasure be good and honourable. And do you, Protagoras, like the rest of the world, call some pleasant things evil and some painful things good?--for I am rather disposed to say that things are good in as far as they are pleasant, if they have no consequences of another sort, and in as far as they are painful they are bad. I do not know, Socrates, he said, whether I can venture to assert in that unqualified manner that the pleasant is the good and the painful the evil. Having regard not only to my present answer, but also to the whole of my life, I shall be safer, if I am not mistaken, in saying that there are some pleasant things which are not good, and that there are some painful things which are good, and some which are not good, and that there are some which are neither good nor evil.
