" Just as in the music of harps and flutes or in the voices of singers a certain harmony of the different tones must be maintained … so also a state is made harmonious by agreement among dissimilar elements. This is brought about by a fair and reasonable blending of the upper, middle and lower classes, just as if they were musical tones. What musicians call harmony in song is concord in a state. "

― Anthony Everitt , Cicero: The Life and Times of Rome's Greatest Politician
