The whole life of the philosopher is a preparation for death.

Man's music is seen as a means of restoring the soul, as well as confused and discordant bodily afflictions, to the harmonic proportions that it shares with the world soul of the cosmos.

True friendship can exist only between equals.

Until philosophers are kings, or the kings and princes of this world have the spirit and power of philosophy, and political greatness and wisdom meet in one, and those commoner natures who pursue either to the exclusion of the other are compelled to stand aside, cities will never have rest from their evils - no, nor the human race, as I believe - and then only will this our State have a possibility of life and behold the light of day.

Music is the movement of sound to reach the soul for the education of its virtue.

You can't do good if you don't feel good.

The blame is his who chooses: God is blameless.
