I do not think that they have, said Protagoras.

'And have you not a similar way of speaking about pain? You call pain a

good when it takes away greater pains than those which it has, or gives

pleasures greater than the pains: then if you have some standard other

than pleasure and pain to which you refer when you call actual pain a

good, you can show what that is. But you cannot.'

True, said Protagoras.

Suppose again, I said, that the world says to me: 'Why do you spend many

words and speak in many ways on this subject?' Excuse me, friends, I

should reply; but in the first place there is a difficulty in explaining

the meaning of the expression 'overcome by pleasure'; and the whole

argument turns upon this. And even now, if you see any possible way in

which evil can be explained as other than pain, or good as other than

pleasure, you may still retract. Are you satisfied, then, at having

a life of pleasure which is without pain? If you are, and if you are

unable to show any good or evil which does not end in pleasure and pain,

hear the consequences:--If what you say is true, then the argument is

absurd which affirms that a man often does evil knowingly, when he might

abstain, because he is seduced and overpowered by pleasure; or again,

when you say that a man knowingly refuses to do what is good because he

is overcome at the moment by pleasure. And that this is ridiculous will

be evident if only we give up the use of various names, such as pleasant

and painful, and good and evil. As there are two things, let us call

them by two names--first, good and evil, and then pleasant and painful.

Assuming this, let us go on to say that a man does evil knowing that he

does evil. But some one will ask, Why? Because he is overcome, is the

first answer. And by what is he overcome? the enquirer will proceed to

ask. And we shall not be able to reply 'By pleasure,' for the name of

pleasure has been exchanged for that of good. In our answer, then, we

shall only say that he is overcome. 'By what?' he will reiterate. By the

good, we shall have to reply; indeed we shall. Nay, but our questioner

will rejoin with a laugh, if he be one of the swaggering sort, 'That is

too ridiculous, that a man should do what he knows to be evil when he

ought not, because he is overcome by good. Is that, he will ask, because

the good was worthy or not worthy of conquering the evil'? And in answer

to that we shall clearly reply, Because it was not worthy; for if it had

been worthy, then he who, as we say, was overcome by pleasure, would not

have been wrong. 'But how,' he will reply, 'can the good be unworthy

of the evil, or the evil of the good'? Is not the real explanation

that they are out of proportion to one another, either as greater and

smaller, or more and fewer? This we cannot deny. And when you speak of

being overcome--'what do you mean,' he will say, 'but that you choose

the greater evil in exchange for the lesser good?' Admitted. And now

substitute the names of pleasure and pain for good and evil, and say,

not as before, that a man does what is evil knowingly, but that he does

what is painful knowingly, and because he is overcome by pleasure,

which is unworthy to overcome. What measure is there of the relations

of pleasure to pain other than excess and defect, which means that they

become greater and smaller, and more and fewer, and differ in degree?

For if any one says: 'Yes, Socrates, but immediate pleasure differs

widely from future pleasure and pain'--To that I should reply: And do

they differ in anything but in pleasure and pain? There can be no

other measure of them. And do you, like a skilful weigher, put into the

balance the pleasures and the pains, and their nearness and distance,

and weigh them, and then say which outweighs the other. If you weigh

pleasures against pleasures, you of course take the more and greater; or

if you weigh pains against pains, you take the fewer and the less; or if

pleasures against pains, then you choose that course of action in which

the painful is exceeded by the pleasant, whether the distant by the near

or the near by the distant; and you avoid that course of action in

which the pleasant is exceeded by the painful. Would you not admit, my

friends, that this is true? I am confident that they cannot deny this.

He agreed with me.

Well then, I shall say, if you agree so far, be so good as to answer me

a question: Do not the same magnitudes appear larger to your sight when

near, and smaller when at a distance? They will acknowledge that.

And the same holds of thickness and number; also sounds, which are in

themselves equal, are greater when near, and lesser when at a distance.

They will grant that also. Now suppose happiness to consist in doing

or choosing the greater, and in not doing or in avoiding the less,

what would be the saving principle of human life? Would not the art of

measuring be the saving principle; or would the power of appearance? Is

not the latter that deceiving art which makes us wander up and down and

take the things at one time of which we repent at another, both in our

actions and in our choice of things great and small? But the art of

measurement would do away with the effect of appearances, and, showing

the truth, would fain teach the soul at last to find rest in the truth,

and would thus save our life. Would not mankind generally acknowledge

that the art which accomplishes this result is the art of measurement?

Yes, he said, the art of measurement.

Suppose, again, the salvation of human life to depend on the choice of

odd and even, and on the knowledge of when a man ought to choose the

greater or less, either in reference to themselves or to each other, and

whether near or at a distance; what would be the saving principle of our

lives? Would not knowledge?--a knowledge of measuring, when the question

is one of excess and defect, and a knowledge of number, when the

question is of odd and even? The world will assent, will they not?

Protagoras himself thought that they would.

Well then, my friends, I say to them; seeing that the salvation of human

life has been found to consist in the right choice of pleasures and

pains,--in the choice of the more and the fewer, and the greater and

the less, and the nearer and remoter, must not this measuring be a

consideration of their excess and defect and equality in relation to

each other?

This is undeniably true.

And this, as possessing measure, must undeniably also be an art and

science?

They will agree, he said.

The nature of that art or science will be a matter of future

consideration; but the existence of such a science furnishes a

demonstrative answer to the question which you asked of me and

Protagoras. At the time when you asked the question, if you remember,

both of us were agreeing that there was nothing mightier than knowledge,

and that knowledge, in whatever existing, must have the advantage over

pleasure and all other things; and then you said that pleasure often got

the advantage even over a man who has knowledge; and we refused to allow

this, and you rejoined: O Protagoras and Socrates, what is the meaning

of being overcome by pleasure if not this?--tell us what you call such a

state:--if we had immediately and at the time answered 'Ignorance,'

you would have laughed at us. But now, in laughing at us, you will be

laughing at yourselves: for you also admitted that men err in their

choice of pleasures and pains; that is, in their choice of good and

evil, from defect of knowledge; and you admitted further, that they err,

not only from defect of knowledge in general, but of that particular

knowledge which is called measuring. And you are also aware that the

erring act which is done without knowledge is done in ignorance. This,

therefore, is the meaning of being overcome by pleasure;--ignorance, and

that the greatest. And our friends Protagoras and Prodicus and Hippias

declare that they are the physicians of ignorance; but you, who are

under the mistaken impression that ignorance is not the cause, and that

the art of which I am speaking cannot be taught, neither go yourselves,

nor send your children, to the Sophists, who are the teachers of these

things--you take care of your money and give them none; and the result

is, that you are the worse off both in public and private life:--Let us

suppose this to be our answer to the world in general: And now I should

like to ask you, Hippias, and you, Prodicus, as well as Protagoras (for

the argument is to be yours as well as ours), whether you think that I

am speaking the truth or not?

They all thought that what I said was entirely true.

Then you agree, I said, that the pleasant is the good, and the painful

evil. And here I would beg my friend Prodicus not to introduce his

distinction of names, whether he is disposed to say pleasurable,

delightful, joyful. However, by whatever name he prefers to call them,

I will ask you, most excellent Prodicus, to answer in my sense of the

words.

Prodicus laughed and assented, as did the others.

Then, my friends, what do you say to this? Are not all actions

honourable and useful, of which the tendency is to make life painless

and pleasant? The honourable work is also useful and good?

This was admitted.

Then, I said, if the pleasant is the good, nobody does anything under

the idea or conviction that some other thing would be better and is also

attainable, when he might do the better. And this inferiority of a man

to himself is merely ignorance, as the superiority of a man to himself

is wisdom.

They all assented.

And is not ignorance the having a false opinion and being deceived about

important matters?

To this also they unanimously assented.

Then, I said, no man voluntarily pursues evil, or that which he thinks

to be evil. To prefer evil to good is not in human nature; and when

a man is compelled to choose one of two evils, no one will choose the

greater when he may have the less.

All of us agreed to every word of this.

Well, I said, there is a certain thing called fear or terror; and here,

Prodicus, I should particularly like to know whether you would agree

with me in defining this fear or terror as expectation of evil.

Protagoras and Hippias agreed, but Prodicus said that this was fear and

not terror.

Never mind, Prodicus, I said; but let me ask whether, if our former

assertions are true, a man will pursue that which he fears when he is

not compelled? Would not this be in flat contradiction to the admission

which has been already made, that he thinks the things which he fears

to be evil; and no one will pursue or voluntarily accept that which he

thinks to be evil?

That also was universally admitted.

Then, I said, these, Hippias and Prodicus, are our premisses; and I

would beg Protagoras to explain to us how he can be right in what he

said at first. I do not mean in what he said quite at first, for his

first statement, as you may remember, was that whereas there were five

parts of virtue none of them was like any other of them; each of them

had a separate function. To this, however, I am not referring, but to

the assertion which he afterwards made that of the five virtues four

were nearly akin to each other, but that the fifth, which was courage,

differed greatly from the others. And of this he gave me the following

proof. He said: You will find, Socrates, that some of the most impious,

and unrighteous, and intemperate, and ignorant of men are among the most

courageous; which proves that courage is very different from the other

parts of virtue. I was surprised at his saying this at the time, and I

am still more surprised now that I have discussed the matter with you.

So I asked him whether by the brave he meant the confident. Yes, he

replied, and the impetuous or goers. (You may remember, Protagoras, that

this was your answer.)

He assented.

Well then, I said, tell us against what are the courageous ready to

go--against the same dangers as the cowards?

No, he answered.

Then against something different?

Yes, he said.

Then do cowards go where there is safety, and the courageous where there

is danger?

Yes, Socrates, so men say.

Very true, I said. But I want to know against what do you say that

the courageous are ready to go--against dangers, believing them to be

dangers, or not against dangers?

No, said he; the former case has been proved by you in the previous

argument to be impossible.

That, again, I replied, is quite true. And if this has been rightly

proven, then no one goes to meet what he thinks to be dangers, since the

want of self-control, which makes men rush into dangers, has been shown

to be ignorance.

He assented.

And yet the courageous man and the coward alike go to meet that about

which they are confident; so that, in this point of view, the cowardly

and the courageous go to meet the same things.

And yet, Socrates, said Protagoras, that to which the coward goes is the

opposite of that to which the courageous goes; the one, for example, is

ready to go to battle, and the other is not ready.

And is going to battle honourable or disgraceful? I said.

Honourable, he replied.

And if honourable, then already admitted by us to be good; for all

honourable actions we have admitted to be good.

That is true; and to that opinion I shall always adhere.

True, I said. But which of the two are they who, as you say, are

unwilling to go to war, which is a good and honourable thing?

The cowards, he replied.

And what is good and honourable, I said, is also pleasant?

It has certainly been acknowledged to be so, he replied.

And do the cowards knowingly refuse to go to the nobler, and pleasanter,

and better?

The admission of that, he replied, would belie our former admissions.

But does not the courageous man also go to meet the better, and

pleasanter, and nobler?

That must be admitted.

And the courageous man has no base fear or base confidence?

True, he replied.

And if not base, then honourable?

He admitted this.

And if honourable, then good?

Yes.

But the fear and confidence of the coward or foolhardy or madman, on the

contrary, are base?

He assented.

And these base fears and confidences originate in ignorance and

uninstructedness?

True, he said.

Then as to the motive from which the cowards act, do you call it

cowardice or courage?
