A similar principle we may imagine to hold good about the minds of men and the natures of their souls.

For when they have been brought up in certain laws, which by some Divine Providence have remained unchanged during long ages, so that no one has any memory or tradition of their ever having been otherwise than they are, then every one is afraid and ashamed to change that which is established.

The legislator must somehow find a way of implanting this reverence for antiquity, and I would propose the following way: People are apt to fancy, as I was saying before, that when the plays of children are altered they are merely plays, not seeing that the most serious and detrimental consequences arise out of the change; and they readily comply with the child's wishes instead of deterring him, not considering that these children who make innovations in their games, when they grow up to be men, will be different from the last generation of children, and, being different, will desire a different sort of life, and under the influence of this desire will want other institutions and laws; and no one of them reflects that there will follow what I just now called the greatest of evils to states.

Changes in bodily fashions are no such serious evils, but frequent changes in the praise and censure of manners are the greatest of evils, and require the utmost prevision.
CLEINIAS: To be sure.
ATHENIAN: And now do we still hold to our former assertion, that rhythms and music in general are imitations of good and evil characters in men?
What say you?
CLEINIAS: That is the only doctrine which we can admit.
ATHENIAN: Must we not, then, try in every possible way to prevent our youth from even desiring to imitate new modes either in dance or song?
nor must any one be allowed to offer them varieties of pleasures.
CLEINIAS: Most true.
ATHENIAN: Can any of us imagine a better mode of effecting this object than that of the Egyptians?
CLEINIAS: What is their method?
ATHENIAN: To consecrate every sort of dance or melody.

First we should ordain festivals--calculating for the year what they ought to be, and at what time, and in honour of what Gods, sons of Gods, and heroes they ought to be celebrated; and, in the next place, what hymns ought to be sung at the several sacrifices, and with what dances the particular festival is to be honoured.
