Music: in aesthetics, science, and "the spheres"

The moral of the story of The Naked Saint relates to how Greeks viewed music. The Greeks believed music could affect humans' behavior. They believed that in order to change a citizen's behavior, all you had to do was change the music. For example, in The Naked Saint, there is a saint who is very depressed and angry with himself. However, once he hears a song for the very first time in his life, he becomes happy.
