[Socrates] The law, I said, which is the sequel of this and of all that has preceded, is to the following effect, "that the wives of our guardians are to be common, and their children are to be com- mon, and no parent is to know his own child, nor any child his parent."

Yes, he said, that is a much greater wave than the other; and the possibility as well as the utility of such a law are far more questionable.

I do not think, I said, that there can be any dispute about the very great utility of having wives and children in common; the possibility is quite another matter, and will be very much disputed.

I think that a good many doubts may be raised about both.

You imply that the two questions must be combined, I re- plied. Now I meant that you should admit the utility; and in this way, as I thought, I should escape from one of them, and then there would remain only the possibility.

But that little attempt is detected, and therefore you will please to give a defence of both.

Well, I said, I submit to my fate. Yet grant me a little favor: let me feast my mind with the dream as day-dreamers are in the habit of feasting themselves when they are walking alone; for before they have discovered any means of effecting their wishes--that is a matter which never troubles them--they would rather not tire themselves by thinking about possibilities; but assuming that what they desire is already granted to them, they proceed with their plan, and delight in detailing what they mean to do when their wish has come true--that is a way which they have of not doing much good to a capacity which was never good for much. Now I myself am beginning to lose heart, and I should like, with your permission, to pass over the question of possibility at present. Assuming therefore the pos- sibility of the proposal, I shall now proceed to inquire how the rulers will carry out these arrangements, and I shall demon- strate that our plan, if executed, will be of the greatest benefit to the Polis and to the guardians. First of all, then, if you have no objection, I will endeavor with your help to consider the advantages of the measure; and hereafter the question of possibility.

I have no objection; proceed.

First, I think that if our rulers and their auxiliaries are to be worthy of the name which they bear, there must be willing- ness to obey in the one and the power of command in the other; the guardians themselves must obey the laws, and they must also imitate the spirit of them in any details which are intrusted to their care.

That is right, he said.

You, I said, who are their legislator, having selected the men, will now select the women and give them to them; they must be as far as possible of like natures with them; and 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. And so they will be drawn by a neces- sity of their natures to have intercourse with each other--ne- cessity is not too strong a word, I think?

Yes, he said; necessity, not geometrical, but another sort of necessity which lovers know, and which is far more convincing and constraining to the mass of mankind.

True, I said; and this, Glaucon, like all the rest, must proceed after an orderly fashion; 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.

Then clearly the next thing will be to make matrimony sacred in the highest degree, and what is most beneficial will be deemed sacred?

Exactly.

And how can marriages be made most beneficial? that is a question which I put to you, because 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 pair- ing and breeding?

In what particulars?

Why, in the first place, although they are all of a good sort, are not some better than others?

True.

And do you breed from them all indifferently, or do you take care to breed from the best only?

From the best.

And do you take the oldest or the youngest, or only those of ripe age?

I choose only those of ripe age.

And if care was not taken in the breeding, your dogs and birds would greatly deteriorate?

Certainly.

And the same of horses and of animals in general?

Undoubtedly.

Good heavens! my dear friend, I said, what consummate skill will our rulers need if the same principle holds of the human species!

Certainly, the same principle holds; but why does this in- volve any particular skill?

Because, I said, our rulers will often have to practise upon the body corporate with medicines. Now you know that when patients do not require medicines, but have only to be put under a regimen, the inferior sort of practitioner is deemed to be good enough; but when medicine has to be given, then the doctor should be more of a man.

That is quite true, he said; but to what are you alluding?

I mean, I replied, that 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 med- icines might be of advantage.

And we were very right.

And this lawful use of them seems likely to be often needed in the regulations of marriages and births.

How so?

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.

Very true.

Had we better not appoint certain festivals at which we will bring together the brides and bridegrooms, and sacrifices will be offered and suitable hymeneal songs composed by our poets: the number of weddings is a matter which must be left to the discretion of the rulers, whose aim will be to preserve the aver- age of population? There are many other things which they will have to consider, such as the effects of wars and diseases and any similar agencies, in order as far as this is possible to prevent the Polis from becoming either too large or too small.

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.

And I think that our braver and better youth, besides their other honors and rewards, might have greater facilities of in- tercourse with women given them; their bravery will be a rea- son, and such fathers ought to have as many sons as possible.

True.

And the proper officers, whether male or female or both, for offices are to be held by women as well as by men-- Yes--

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 great- est possible care that no mother recognizes her own child; and other wet-nurses may be engaged if more are required. Care will also be taken that the process of suckling shall not be pro- tracted too long; and the mothers will have no getting up at night or other trouble, but will hand over all this sort of thing to the nurses and attendants.

You suppose the wives of our guardians to have a fine easy time of it when they are having children.

Why, said I, and so they ought. Let us, however, proceed with our scheme. We were saying that the parents should be in the prime of life?

Very true.

And what is the prime of life? May it not be defined as a period of about twenty years in a woman's life, and thirty years in a man's?

Which years do you mean to include?

A woman, I said, at twenty years of age may begin to bear children to the Polis, and continue to bear them until forty; a man may begin at five-and-twenty, when he has passed the point at which the pulse of life beats quickest, and continue to beget children until he be fifty-five.

Certainly, he said, both in men and women those years are the prime of physical as well as of intellectual vigor. Anyone above or below the prescribed ages who takes part in the public hymeneals shall be said to have done an unholy and unrighteous thing; the child of which he is the father, if it steals into life, will have been conceived under auspices very unlike the sacrifices and prayers, which at each hymeneal priest- esses and priests and the whole city will offer, that the new generation may be better and more useful than their good and useful parents, whereas his child will be the offspring of dark- ness and strange lust.

Very true, he replied.

And the same law will apply to any one of those within the prescribed age who forms a connection with any woman in the prime of life without the sanction of the rulers; for we shall say that he is raising up a bastard to the Polis, uncertified and unconsecrated.

Very true, he replied.

This applies, however, only to those who are within the spec- ified age: after that we will allow them to range at will, except that a man may not marry his daughter or his daughter's daughter, or his mother or his mother's mother; and women, on the other hand, are prohibited from marrying their sons or fathers, or son's son or father's father, and so on in either di- rection. And we grant all this, accompanying the permission with strict orders to prevent any embryo which may come into being from seeing the light; and if any force a way to the birth, the parents must understand that the offspring of such a union cannot be maintained, and arrange accordingly.

That also, he said, is a reasonable proposition. But how will they know who are fathers and daughters, and so on?

They will never know. The way will be this: dating from the day of the hymeneal, the bridegroom who was then married will call all the male children who are born in the seventh and the tenth month afterward 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 genera- tion 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. This, however, is not to be understood as an absolute prohibition of the marriage of brothers and sisters; if the lot favors them, and they receive the sanction of the Pythian oracle, the law will allow them.

Quite right, he replied.
