Plutarch (c. 50-120)
“By definition foreigners must bring in foreign ideas with them, and novel ideas lead to novel attitudes. Hence inevitably many emotions and preferences emerge which – if the existing government be likened to a piece of music – are out of tune with it.”
- On Sparta (Life of Lycurgus), excerpted from Plutarch’s Parallel Lives, translated by Richard J. A. Talbert. New York: Penguin Classics, 2005.
