Sculpture and painting equally with music must conform to the law of simplicity.

He who violates it cannot be allowed to work in our city, and to corrupt the taste of our citizens.

For our guardians must grow up, not amid images of deformity which will gradually poison and corrupt their souls, but in a land of health and beauty where they will drink in from every object sweet and harmonious influences.

And of all these influences the greatest is the education given by music, which finds a way into the innermost soul and imparts to it the sense of beauty and of deformity.

At first the effect is unconscious; but when reason arrives, then he who has been thus trained welcomes her as the friend whom he always knew.
