All young creatures love motion and frolic, and utter sounds of delight; but man only is capable of taking pleasure in rhythmical and harmonious movements.

With these education begins; and the uneducated is he who has never known the discipline of the chorus, and the educated is he who has.

The chorus is partly dance and partly song, and therefore the well-educated must sing and dance well.

But when we say, 'He sings and dances well,' we mean that he sings and dances what is good.

And if he thinks that to be good which is really good, he will have a much higher music and harmony in him, and be a far greater master of imitation in sound and gesture than he who is not of this opinion.
