SUCH is the good and true City or State, and the good and man is of the same pattern; and if this is right every other is wrong; and the evil is one which affects not only the ordering of the State, but also the regulation of the individual soul.
We have been long expecting that you would tell us something about the family life of your citizens--how they will bring children into the world, and rear them when they have arrived...  What sort of community of women and children is this which is to prevail among our guardians? and how shall we manage the period between birth and education, which seems to require the greatest care?...
...If women are to have the same duties as men, they must have the same nurture and education? 
 Is she capable of sharing either wholly or partially in the actions of men, or not at all?... And if, I said, the male and female sex appear to differ in their fitness for any art or pursuit, we should say that such pursuit or art ought to be assigned to one or the other of them; but if the difference consists only in women bearing and men begetting children, this does not amount to a proof that a woman differs from a man in respect of the sort of education she should receive; and we shall therefore continue to maintain that our guardians and their wives ought to have the same pursuits.
Very true, he said.
Next, we shall ask our opponent how...  the nature of a woman differs from that of a man?... Let us say to him: Come now, and we will ask you a question:--when you spoke of a nature gifted or not gifted in any respect, did you mean to say that one man will acquire a thing easily, another with difficulty; a little learning will lead the one to discover a great deal; whereas the other, after much study and application, no sooner learns than he forgets; ... -would not these be the sort of differences which distinguish the man gifted by nature from the one who is ungifted?
No one will deny that...
Then one woman will have the temper of a guardian, and another not. Was not the selection of the male guardians determined by differences of this sort?
Men and women alike possess the qualities which make a guardian; they differ only in their comparative strength or weakness.
And those women who have such qualities are to be selected as the companions and colleagues of men who have similar qualities and whom they resemble in capacity and in character?
And ought not the same natures to have the same pursuits?
Would you say that all men are equal in excellence, or is one man better than another?
And can there be anything better for the interests of the State than that the men and women of a State should be as good as possible?
There can be nothing better. ...
Then let the wives of our guardians strip, for their virtue will be their robe, and let them share in the toils of war and the defence of their country; only in the distribution of labours the lighter are to be assigned to the women, who are the weaker natures, but in other respects their duties are to be the same...
...’The wives of our guardians are to be common, and their children are to be common, and no parent is to know his own child, nor any child his parent.'... ...they must live in common houses and meet at common meals, None of them will have anything specially his or her own; they will be together, and will be brought up together, and will associate at gymnastic exercises...in a city of the blessed, licentiousness is an unholy thing which the rulers will forbid.
Yes, he said, and it ought not to be permitted...
...I see in your house dogs for hunting, and of the nobler sort of birds not a few. Now, I beseech you, do tell me, have you ever attended to their pairing and breeding? ...do you breed from them all indifferently, or do you take care to breed from the best only?
From the best...
Good heavens! my dear friend, I said, what consummate skill will our rulers need if the same principle holds of the human species! ...our rulers will find a considerable dose of falsehood and deceit necessary for the good of their subjects: we were saying that the use of all these things regarded as medicines might be of advantage.
And we were very right.
Why, I said, the principle has been already laid down that the best of either sex should be united with the best as often, and the inferior with the inferior, as seldom as possible; and that they should rear the offspring of the one sort of union, but not of the other, if the flock is to be maintained in first-rate condition. Now these goings on must be a secret which the rulers only know, or there will be a further danger of our herd, as the guardians may be termed, breaking out into rebellion.
Had we not better appoint certain festivals at which we will bring together the brides and bridegrooms,  ...to preserve the average of population?...
Certainly, he replied.
We shall have to invent some ingenious kind of lots which the less worthy may draw on each occasion of our bringing them together, and then they will accuse their own ill-luck and not the rulers.
To be sure, he said...
The proper officers will take the offspring of the good parents to the pen or fold, and there they will deposit them with certain nurses who dwell in a separate quarter; but the offspring of the inferior, or of the better when they chance to be deformed, will be put away in some mysterious, unknown place, as they should be.
Yes, he said, that must be done if the breed of the guardians is to be kept pure.
They will provide for their nurture, and will bring the mothers to the fold when they are full of milk, taking the greatest possible care that no mother recognizes her own child...  ...the bridegroom who was then married will call the male children who are born in the seventh and ten month afterwards his sons, and the female children his daughters, and they will call him father, and he will call their children his grandchildren, and they will call the elder generation grandfathers and grandmothers. All who were begotten at the time when their fathers and mothers came together will be called their brothers and sisters, and these, as I was saying, will be forbidden to intermarry...
...Is not that the best-ordered State in which the greatest number of persons apply the terms `mine' and `not mine' in the same way to the same thing?
Quite true... 
...Then the community of wives and children among our citizens is clearly the source of the greatest good to the State?
And this agrees with the other principle which we were affirming,--that the guardians were not to have houses or lands or any other property; their pay was to be their food, which they were to receive from the other citizens, and they were to have no private expenses; for we intended them to preserve their true character of guardians.
Right, he replied.
Both the community of property and the community of families, as I am saying, tend to make them more truly guardians; they will not tear the city in pieces by differing about `mine' and `not mine;' each man dragging any acquisition which he has made into a separate house of his own, where he has a separate wife and children and private pleasures and pains; but all will be affected as far as may be
by the same pleasures and pains because they are all of one opinion about what is near and dear to them, and therefore they all tend towards a common end.
Certainly, he replied.
And as they have nothing but their persons which they can call their own, suits and complaints will have no existence among them; they will be delivered from all those quarrels of which money or children or relations are the occasion.
Of course they will... 
You agree then, I said, that men and women are to have a common way of life such as we have described--common education, common children; and they are to watch over the citizens in common whether abiding in the city or going out to war; they are to keep watch together, and to hunt together like dogs; and always and in all things, as far as they are able, women are to share with the men? And in so doing they will do what is best, and will not violate, but preserve the natural relation of the sexes.
I agree with you, he replied... 
...I should be inclined to propose that the soldier who leaves his rank or throws away his arms, or is guilty of any other act of cowardice, should be degraded into the rank of a husbandman or artisan. What do you think?
By all means, I should say...
But the hero who has distinguished himself, what shall be done to him? In the first place, he shall receive honour in the army from his youthful comrades; every one of them in succession shall crown him. What do you say?
...the brave man is to have more wives than others has been already determined: and he is to have first choices in such matters more than others, in order that he may have as many children as possible?
But still I must say, Socrates, that if you are allowed to go on in this way you will entirely forget the other question which at the commencement of this discussion you thrust aside:-- Is such an order of things possible, and how, if at all? ...
We are enquiring into the nature of absolute justice and into the character of the perfectly just, and into injustice and the perfectly unjust, that we might have an ideal. We were to look at these in order that we might judge of our own happiness and unhappiness according to the standard which they exhibited and the degree in which we resembled them, but not with any view of showing that they could exist in fact.
True, he said.
Would a painter be any the worse because, after having delineated with consummate art an ideal of a perfectly beautiful man, he was unable to show that any such man could ever have existed?
He would be none the worse.
Well, and were we not creating an ideal of a perfect State?
To be sure.
And is our theory a worse theory because we are unable to prove the possibility of a city being ordered in the manner described?
Surely not, he replied.
That is the truth, I said. But if, at your request, I am to try and show how and under what conditions the possibility is highest, I must ask you, having this in view, to repeat your former admissions.
 I want to know whether ideals are ever fully realised in language? Does not the word express more than the fact, and must not the actual, whatever a man may think, always, in the nature of things, fall short of the truth? What do you say?
Then you must not insist on my proving that the actual State will in every respect coincide with the ideal: if we are only able to discover how a city may be governed nearly as we proposed, you will admit that we have discovered the possibility which you demand; and will be contented. I am sure that I should be contented--will not you?
Yes, I will.
Let me next endeavour to show what is that fault in States which is the cause of their present maladministration, and what is the least change which will enable a State to pass into the truer form; and let the change, if possible, be of one thing only, or if not, of two; at any rate, let the changes be as few and slight as possible.
Certainly, he replied.
I think, I said, that there might be a reform of the State if only one change were made, which is not a slight or easy though still a possible one.
What is it? he said.
Now then, I said, I go to meet that which I liken to the greatest of the waves; yet shall the word be spoken, even though the wave break and drown me in laughter and dishonour; and do you mark my words.
I said: Until philosophers are kings, or the kings and princes of this world have the spirit and power of philosophy, and political greatness and wisdom meet in one, and those commoner natures who pursue either to the exclusion of the other are compelled to stand aside, cities will never have rest from their evils,--nor the human race, as I believe,--and then only will this our State have a possibility of life and behold the light of day. Such was the thought, my dear Glaucon, which I would fain have uttered if it had not seemed too extravagant; for to be convinced that in no other State can there be happiness private or public is indeed a hard thing.
Socrates, what do you mean? I would have you consider that the word which you have uttered is one at which numerous persons, and very respectable persons too,  in a figure pulling off their coats all in a moment, and seizing any weapon that comes to hand, will run at you might and main, before you know where you are, intending to do heaven knows what; and if you don't prepare an answer, and put yourself in motion, you will be prepared by their fine wits,' and no mistake.
You got me into the scrape, I said.
And I was quite right; however, I will do all I can to get you out of it; but I can only give you good-will and good advice, and, perhaps, I may be able to fit answers to your questions better than another-- that is all. And now, having such an auxiliary, you must do your best to show the unbelievers that you are right.
I ought to try, I said, since you offer me such invaluable assistance. And I think that, if there is to be a chance of our escaping, we must explain to them whom we mean when we say that philosophers are to rule in the State; then we shall be able to defend ourselves: There will be discovered to be some natures who ought to study philosophy and to be leaders in the State; and others who are not born to be philosophers, and are meant to be followers rather than leaders.
Then now for a definition, he said.
Follow me, I said, and I hope that I may in some way or other be able to give you a satisfactory explanation.
...May we not say of the philosopher that he is a lover, not of a part of wisdom only, but of the whole?
Yes, of the whole.
And he who dislikes learnings, especially in youth, when he has no power of judging what is good and what is not, such an one we maintain not to be a philosopher or a lover of knowledge, just as he who refuses his food is not hungry, and may be said to have a bad appetite and not a good one?
Very true, he said.
Whereas he who has a taste for every sort of knowledge and who is curious to learn and is never satisfied, may be justly termed a philosopher? Am I not right?
Glaucon said: If curiosity makes a philosopher, you will find many a strange being will have a title to the name...
...He said: Who then are the true philosophers?
Those, I said, who are lovers of the vision of truth.
That is also good, he said; but I should like to know what you mean?... 
And this is the distinction which I draw between the sight-loving, art-loving, practical class and those of whom I am speaking, and who are alone worthy of the name of philosophers.
How do you distinguish them? he said.
The lovers of sounds and sights, I replied, are, as I conceive, fond of fine tones and colours and forms and all the artificial products that are made out of them, but their mind is incapable of seeing or loving absolute beauty.
True, he replied...
But take the case of the other, who recognises the existence of absolute beauty and is able to distinguish the idea from the objects which participate in the idea, neither putting the objects in the place of the idea nor the idea in the place of the objects-- is he a dreamer, or is he awake?
He is wide awake.
And may we not say that the mind of the one who knows has knowledge, and that the mind of the other, who opines only, has opinion
Then opinion and knowledge have to do with different kinds of matter corresponding to this difference of faculties?
And knowledge is relative to being and knows being...
...Would you say that knowledge is a faculty, or in what class would you
Certainly knowledge is a faculty, and the mightiest of all faculties.
And is opinion also a faculty?
Certainly, he said; for opinion is that with which we are able to form an opinion... 
Then knowledge and opinion having distinct powers have also distinct spheres or subject-matters?
That is certain.
Being is the sphere or subject-matter of knowledge, and knowledge is to know the nature of being?
Of not-being, ignorance was assumed to be the necessary correlative; of being, knowledge?
True, he said.
Then opinion is not concerned either with being or with not-being?
Not with either.
And can therefore neither be ignorance nor knowledge?
That seems to be true...
Then I suppose that opinion appears to you to be darker than knowledge, but lighter than ignorance?
Both; and in no small degree... 
Thus then we seem to have discovered that the many ideas which the multitude entertain about the beautiful and about all other things are tossing about in some region which is halfway between pure being and pure not-being?
Then those who see the many beautiful, and who yet neither see absolute beauty, nor can follow any guide who points the way thither; who see the many just, and not absolute justice, and the like,-- such persons may be said to have opinion but not knowledge?
That is certain.
But those who see the absolute and eternal and immutable may be said to know, and not to have opinion only?
Neither can that be denied.
The one loves and embraces the subjects of knowledge, the other those of opinion?...  Shall we then be guilty of any impropriety in calling them lovers of opinion rather than lovers of wisdom, and will they be very angry with us for thus describing them?
I shall tell them not to be angry; no man should be angry at what is true.
But those who love the truth in each thing are to be called lovers of wisdom and not lovers of opinion.
