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 Ishould 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.
And you would call pleasant, I said, the things which participate in pleasure or create pleasure?
Certainly, he said.
Then my meaning is, that in as far as they are pleasant they are good; and my question would imply that pleasure is a good in itself.
According to your favourite mode of speech, Socrates, "Let us reflect about this," he said; and if the reflection is to the point, and the result proves that pleasure and good are really the same, then we will agree; but if not, then we will argue.
And would you wish to begin the enquiry?
I said; or shall I begin?
You ought to take the lead, he said; for you are the author of the discussion.
May I employ an illustration? I said. Suppose some one who is enquiring into the health or some other bodily quality of another:-he looks at his face and at the tips of his fingers, and then he says, Uncover your chest and back to me that I may have a better view:-that is the sort of thing which I desire in this speculation.
Having seen what your opinion is about good and pleasure, I am minded to say to you: Uncover your mind to me, Protagoras, and reveal your opinion about knowledge, that I may know whether you agree with the rest of the world. Now the rest of the world are of opinion that knowledge is a principle not of strength, or of rule, or of command: their notion is that a man may have knowledge, and yet that the knowledge which is in him may be overmastered by anger, or pleasure, or pain, or love, or perhaps by fear,-just as if knowledge were a slave, and might be dragged about anyhow. Now is that your view? or do you think that knowledge is a noble and commanding thing, which cannot be overcome, and will not allow a man, if he only knows the difference of good and evil, to do anything which is contrary to knowledge, but that wisdom will have strength to help him?
I agree with you, Socrates, said Protagoras; and not only so, but I, above all other men, am bound to say that wisdom and knowledge are the highest of human things.
Good, I said, and true. But are you aware that the majority of the world are of another mind; and that men are commonly supposed to know the things which are best, and not to do them when they might?
And most persons whom I have asked the reason of this have said that when men act contrary to knowledge they are overcome by pain, or pleasure, or some of those affections which I was just now mentioning.
Yes, Socrates, he replied; and that is not the only point about which mankind are in error.
Suppose, then, that you and I endeavour to instruct and inform them what is the nature of this affection which they call "being overcome by pleasure," and which they affirm to be the reason why they do not always do what is best. When we say to them: Friends, you are mistaken, and are saying what is not true, they would probably reply: Socrates and Protagoras, if this affection of the soul is not to be called "being overcome by pleasure," pray, what is it, and by what name would you describe it?
But why, Socrates, should we trouble ourselves about the opinion of the many, who just say anything that happens to occur to them?
I believe, I said, that they may be of use in helping us to discover how courage is related to the other parts of virtue. If you are disposed to abide by our agreement, that I should show the way in which, as I think, our recent difficulty is most likely to be cleared up, do you follow; but if not, never mind.
You are quite right, he said; and I would have you proceed as you have begun.
