defect in the division is cured.  And the truth of this may be easily proved when we have leisure.  But for the present, trusting to the mere assertion of this principle, let us divide the state; and assigning to each portion some God or son of a God, let us give them altars and sacred rites, and at the altars let us hold assemblies for sacrifice twice in the month—­twelve assemblies for the tribes, and twelve for the city, according to their divisions; the first in honour of the Gods and divine things, and the second to promote friendship and ’better acquaintance,’ as the phrase is, and every sort of good fellowship with one another.  For people must be acquainted with those into whose families and whom they marry and with those to whom they give in marriage; in such matters, as far as possible, a man should deem it all important to avoid a mistake, and with this serious purpose let games be instituted (compare Republic) in which youths and maidens shall dance together, seeing one another and being seen naked, at a proper age, and on a suitable occasion, not transgressing the rules of modesty.

The directors of choruses will be the superintendents and regulators of these games, and they, together with the guardians of the law, will legislate in any matters which we have omitted; for, as we said, where there are numerous and minute details, the legislator must leave out something.  And the annual officers who have experience, and know what is wanted, must make arrangements and improvements year by year, until such enactments and provisions are sufficiently determined.  A ten years’ experience of sacrifices and dances, if extending to all particulars, will be quite sufficient; and if the legislator be alive they shall communicate with him, but if he be dead then the several officers shall refer the omissions which come under their notice to the guardians of the law, and correct them, until all is perfect; and from that time there shall be no more change, and they shall establish and use the new laws with the others which the legislator originally gave them, and of which they are never, if they can help, to change aught; or, if some necessity overtakes them, the magistrates must be called into counsel, and the whole people, and they must go to all the oracles of the Gods; and if they are all agreed, in that case they may make the change, but if they are not agreed, by no manner of means, and any one who dissents shall prevail, as the law ordains.

Whenever any one over twenty-five years of age, having seen and been seen by others, believes himself to have found a marriage connexion which is to his mind, and suitable for the procreation of children, let him marry if he be still under the age of five-and-thirty years; but let him first hear how he ought to seek after what is suitable and appropriate (compare Arist.  Pol.).  For, as Cleinias says, every law should have a suitable prelude.

Cleinias:  You recollect at the right moment, Stranger, and do not miss the opportunity which the argument affords of saying a word in season.
