“ Music is more powerful than reason in the soul. That is also why Plato made music the very first step in his long educational curriculum: good music was to create the harmony of soul that would be a ripe field for the higher harmony of reason to take root in later. And that is also why he said that the decay of the ideal state would begin with a decay in music. In fact, one of your obscure modern scholars has shown that social and political revolutions have usually been preceded by musical revolutions, and why another sage said, 'Let me write the songs of a nation and I care not who writes its laws. ”
