When we had got to this point in the argument, and every- one saw that the definition of justice had been completely upset, Thrasymachus, instead of replying to me, said, Tell me, Soc- rates, have you got a nurse?

Why do you ask such a question, I said, when you ought rather to be answering?

Because she leaves you to snivel, and never wipes your nose: she has not even taught you to know the shepherd from the sheep.

What makes you say that? I replied.

Because you fancy that the shepherd or neatherd fattens or tends the sheep or oxen with a view to their own good and not to the good of himself or his master; and you further imagine that the rulers of States, if they are true rulers, never think of their subjects as sheep, and that they are not studying their own advantage day and night. Oh, no; and so entirely astray are you in your ideas about the just and unjust as not even to know that justice and the just are in reality another's good; that is to say, the interest of the ruler and stronger, and the loss of the subject and servant; and injustice the opposite; for the unjust is lord over the truly simple and just: he is the stronger, and his subjects do what is for his interest, and min- ister to his happiness, which is very far from being their own. Consider further, most foolish Socrates, that the just is always a loser in comparison with the unjust. First of all, in private contracts: wherever the unjust is the partner of the just you will find that, when the partnership is dissolved, the unjust man has always more and the just less. Secondly, in their dealings with the State: when there is an income-tax, the just man will pay more and the unjust less on the same amount of income; and when there is anything to be received the one gains nothing and the other much. Observe also what happens when they take an office; there is the just man neglecting his affairs and perhaps suffering other losses, and getting nothing out of the public, because he is just; moreover he is hated by his friends and acquaintance for refusing to serve them in unlaw- ful ways. But all this is reversed in the case of the unjust man. I am speaking, as before, of injustice on a large scale in which the advantage of the unjust is most apparent; and my meaning will be most clearly seen if we turn to that highest form of injustice in which the criminal is the happiest of men, and the sufferers or those who refuse to do injustice are the most miserable--that is to say tyranny, which by fraud and force takes away the property of others, not little by little but wholesale; comprehending in one, things sacred as well as pro- fane, private and public; for which acts of wrong, if he were detected perpetrating any one of them singly, he would be pun- ished and incur great disgrace--they who do such wrong in particular cases are called robbers of temples, and man-stealers and burglars and swindlers and thieves. But when a man be- sides taking away the money of the citizens has made slaves of them, then, instead of these names of reproach, he is termed happy and blessed, not only by the citizens but by all who hear of his having achieved the consummation of injustice. For mankind censure injustice, fearing that they may be the vic- tims of it and not because they shrink from committing it. And thus, as I have shown, Socrates, injustice, when on a suffi- cient scale, has more strength and freedom and mastery than justice; and, as I said at first, justice is the interest of the stronger, whereas injustice is a man's own profit and interest.

Thrasymachus, when he had thus spoken, having, like a bath- man, deluged our ears with his words, had a mind to go away. But the company would not let him; they insisted that he should remain and defend his position; and I myself added my own humble request that he would not leave us. Thrasyma- chus, I said to him, excellent man, how suggestive are your re- marks! And are you going to run away before you have fairly taught or learned whether they are true or not? Is the attempt to determine the way of man's life so small a matter in your eyes--to determine how life may be passed by each one of us to the greatest advantage?

And do I differ from you, he said, as to the importance of the inquiry?

You appear rather, I replied, to have no care or thought about us, Thrasymachus--whether we live better or worse from not knowing what you say you know, is to you a matter of indifference. Prithee, friend, do not keep your knowledge to yourself; we are a large party; and any benefit which you confer upon us will be amply rewarded. For my own part I openly declare that I am not convinced, and that I do not be- lieve injustice to be more gainful than justice, even if uncon- trolled and allowed to have free play. For, granting that there may be an unjust man who is able to commit injustice either by fraud or force, still this does not convince me of the superior advantage of injustice, and there may be others who are in the same predicament with myself. Perhaps we may be wrong; if so, you in your wisdom should convince us that we are mis- taken in preferring justice to injustice.

And how am I to convince you, he said, if you are not already convinced by what I have just said; what more can I do for you? Would you have me put the proof bodily into your souls?

Heaven forbid! I said; I would only ask you to be consistent; or, if you change, change openly and let there be no deception. For I must remark, Thrasymachus, 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 exact- ness 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 shep- herd 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 insured whenever all the requirements of it are satis- fied. And that was what I was saying just now about the ruler. I conceived that the art of the ruler, considered as a 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; naviga- tion, 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 voy- age. You would not be inclined to say, would you? that navi- gation 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 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 ad- vantage 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.
