In the case of the seasons and winds, in the management of our bodies and in the habits of our minds, change is a dangerous thing.

And in everything but what is bad the same rule holds.

We all venerate and acquiesce in the laws to which we are accustomed; and if they have continued during long periods of time, and there is no remembrance of their ever having been otherwise, people are absolutely afraid to change them.

Now how can we create this quality of immobility in the laws?
I say, by not allowing innovations in the games and plays of children.

The children who are always having new plays, when grown up will be always having new laws.
Changes in mere fashions are not serious evils, but changes in our estimate of men's characters are most serious; and rhythms and music are representations of characters, and therefore we must avoid novelties in dance and song.
