if you will recall what was previously said, that although you began by defining the true physician in an exact sense, you did not observe a like exactness when speaking of the shepherd; you thought that the shepherd as a shepherd tends the sheep not with a view to their own good, but like a mere diner or banqueter with a view to the pleasures of the table; or, again, as a trader for sale in the market, and not as a shepherd. Yet surely the art of the shepherd is concerned only with the good of his subjects; he has only to provide the best for them, since the perfection of the art is already ensured whenever all the requirements of it are satisfied. And that was what I was saying just now about the ruler. I conceived that the art of the ruler, considered as ruler, whether in a state or in private life, could only regard the good of his flock or subjects; whereas you seem to think that the rulers in states, that is to say, the true rulers, like being in authority.
Think! Nay, I am sure of it.
Then why in the case of lesser offices do men never take them willingly without payment, unless under the idea that they govern for the advantage not of themselves but of others? Let me ask you a question: Are not the several arts different, by reason of their each having a separate function? And, my dear illustrious friend, do say what you think, that we may make a little progress.
Yes, that is the difference, he replied.
And each art gives us a particular good and not merely a general one—medicine, for example, gives us health; navigation, safety at sea, and so on?
Yes, he said.
And the art of payment has the special function of giving pay: but we do not confuse this with other arts, any more than the art of the pilot is to be confused with the art of medicine, because the health of the pilot may be improved by a sea voyage. You would not be inclined to say, would you, that navigation is the art of medicine, at least if we are to adopt your exact use of language?
Certainly not.
Or because a man is in good health when he receives pay you would not say that the art of payment is medicine?
I should say not.
Nor would you say that medicine is the art of receiving pay because a man takes fees when he is engaged in healing?
Certainly not.
And we have admitted, I said, that the good of each art is specially confined to the art?
Yes.
Then, if there be any good which all artists have in common, that is to be attributed to something of which they all have the common use?
True, he replied.
And when the artist is benefited by receiving pay the advantage is gained by an additional use of the art of pay, which is not the art professed by him?
He gave a reluctant assent to this.
Then the pay is not derived by the several artists from their respective arts. But the truth is, that while the art of medicine gives health, and the art of the builder builds a house, another art attends them which is the art of pay. The various arts may be doing their own business and benefiting that over which they preside, but would the artist receive any benefit from his art unless he were paid as well?
I suppose not.
But does he therefore confer no benefit when he works for nothing?
Certainly, he confers a benefit.
Then now, Thrasymachus, there is no longer any doubt that neither arts nor governments provide for their own interests; but, as we were before saying, they rule and provide for the interests of their subjects who are the weaker and not the stronger—to their good they attend and not to the good of the superior.
And this is the reason, my dear Thrasymachus, why, as I was just now saying, no one is willing to govern; because no one likes to take in hand the reformation of evils which are not his concern without remuneration. For, in the execution of his work, and in giving his orders to another, the true artist does not regard his own interest, but always that of his subjects; and therefore in order that rulers may be willing to rule, they must be paid in one of three modes of payment: money, or honour, or a penalty for refusing.
SOCRATES - GLAUCON
What do you mean, Socrates? said Glaucon. The first two modes of payment are intelligible enough, but what the penalty is I do not understand, or how a penalty can be a payment.
You mean that you do not understand the nature of this payment which to the best men is the great inducement to rule? Of course you know that ambition and avarice are held to be, as indeed they are, a disgrace?
Very true.
And for this reason, I said, money and honour have no attraction for them; good men do not wish to be openly demanding payment for governing and so to get the name of hirelings, nor by secretly helping themselves out of the public revenues to get the name of thieves. And not being ambitious they do not care about honour. Wherefore necessity must be laid upon them, and they must be induced to serve from the fear of punishment. And this, as I imagine, is the reason why the forwardness to take office, instead of waiting to be compelled, has been deemed dishonourable. Now the worst part of the punishment is that he who refuses to rule is liable to be ruled by one who is worse than himself. And the fear of this, as I conceive, induces the good to take office, not because they would, but because they cannot help—not under the idea that they are going to have any benefit or enjoyment themselves, but as a necessity, and because they are not able to commit the task of ruling to any one who is better than themselves, or indeed as good. For there is reason to think that if a city were composed entirely of good men, then to avoid office would be as much an object of contention as to obtain office is at present; then we should have plain proof that the true ruler is not meant by nature to regard his own interest, but that of his subjects; and every one who knew this would choose rather to receive a benefit from another than to have the trouble of conferring one. So far am I from agreeing with Thrasymachus that justice is the interest of the stronger. This latter question need not be further discussed at present; but when Thrasymachus says that the life of the unjust is more advantageous than that of the just, his new statement appears to me to be of a far more serious character. Which of us has spoken truly? And which sort of life, Glaucon, do you prefer?
I for my part deem the life of the just to be the more advantageous, he answered.
Did you hear all the advantages of the unjust which Thrasymachus was rehearsing?
Yes, I heard him, he replied, but he has not convinced me.
Then shall we try to find some way of convincing him, if we can, that he is saying what is not true?
Most certainly, he replied.
If, I said, he makes a set speech and we make another recounting all the advantages of being just, and he answers and we rejoin, there must be a numbering and measuring of the goods which are claimed on either side, and in the end we shall want judges to decide; but if we proceed in our enquiry as we lately did, by making admissions to one another, we shall unite the offices of judge and advocate in our own persons.
Very good, he said.
And which method do I understand you to prefer? I said.
That which you propose.
Well, then, Thrasymachus, I said, suppose you begin at the beginning and answer me. You say that perfect injustice is more gainful than perfect justice?
SOCRATES - GLAUCON - THRASYMACHUS
Yes, that is what I say, and I have given you my reasons.
And what is your view about them? Would you call one of them virtue and the other vice?
Certainly.
I suppose that you would call justice virtue and injustice vice?
What a charming notion! So likely too, seeing that I affirm injustice to be profitable
