The intention was, that, in the case of the citizens generally, each individual should be put to the use for which nature which nature intended him, one to one work, and then every man would do his own business, and be one and not many; and so the whole city would be one and not many.
Yes, he said; that is not so difficult.
The regulations which we are prescribing, my good Adeimantus, are not, as might be supposed, a number of great principles, but trifles all, if care be taken, as the saying is, of the one great thing,--a thing, however, which I would rather call, not great, but sufficient for our purpose.
What may that be?
he asked.
Education, I said, and nurture: If our citizens are well educated, and grow into sensible men, they will easily see their way through all these, as well as other matters which I omit; such, for example, as marriage, the possession of women and the procreation of children, which will all follow the general principle that friends have all things in common, as the proverb says.
That will be the best way of settling them.
Also, I said, the State, if once started well, moves with accumulating force like a wheel.

For good nurture and education implant good constitutions, and these good constitutions taking root in a good education improve more and more, and this improvement affects the breed in man as in other animals.
Very possibly, he said.
Then to sum up: This is the point to which, above all, the attention of our rulers should be directed,--that music and gymnastic be preserved in their original form, and no innovation made.

They must do their utmost to maintain them intact.

And when any one says that mankind most regard The newest song which the singers have, they will be afraid that he may be praising, not new songs, but a new kind of song; and this ought not to be praised, or conceived to be the meaning of the poet; for any musical innovation is full of danger to the whole State, and ought to be prohibited.

So Damon tells me, and I can quite believe him;-he says that when modes of music change, of the State always change with them.
Yes, said Adeimantus; and you may add my suffrage to Damon's and your own.
Then, I said, our guardians must lay the foundations of their fortress in music?
Yes, he said; the lawlessness of which you speak too easily steals in.
Yes, I replied, in the form of amusement; and at first sight it appears harmless.
Why, yes, he said, and there is no harm; were it not that little by little this spirit of licence, finding a home, imperceptibly penetrates into manners and customs; whence, issuing with greater force, it invades contracts between man and man, and from contracts goes on to laws and constitutions, in utter recklessness, ending at last, Socrates, by an overthrow of all rights, private as well as public.
Is that true?
I said.
That is my belief, he replied.
Then, as I was saying, our youth should be trained from the first in a stricter system, for if amusements become lawless, and the youths themselves become lawless, they can never grow up into well-conducted and virtuous citizens.
Very true, he said.
And when they have made a good beginning in play, and by the help of music have gained the habit of good order, then this habit of order, in a manner how unlike the lawless play of the others! will accompany them in all their actions and be a principle of growth to them, and if there be any fallen places a principle in the State will raise them up again.
Very true, he said.
Thus educated, they will invent for themselves any lesser rules which their predecessors have altogether neglected.
What do you mean?
I mean such things as these:--when the young are to be silent before their elders; how they are to show respect to them by standing and making them sit; what honour is due to parents; what garments or shoes are to be worn; the mode of dressing the hair; deportment and manners in general.
