Harmony sinks deep into the recesses of the soul and takes its strongest hold there, bringing grace also to the body & mind as well. Music is a moral law. It gives a soul to the universe, wings to the mind, flight to the imagination, a charm to sadness, and life to everything. It is the essence of order.

PlatoAny city, however small, is in fact divided into two, one the city of the poor, the other of the rich; these are at war with one another.
