FREEDOM—“I am sure there was no word for freedom before slavery was invented. The old Greeks had every sort of government—monarchies, aristocracies, plutocracies, democracies—and argued fiercely about which system gave people most freedom, but all of them kept slaves. So did the ancient Roman republic. So did the stout squires who founded the U.S.A. Yes, the only sure definition of freedom is non-slavery.
