 Montesquieu advocated reform of slavery in "The Spirit of Law".As part of his advocacy he presented a satirical hypothetical list of arguments for slavery.While addressing French readers of his "General Theory", John Maynard Keynes described Montesquieu as "the real French equivalent of Adam Smith, the greatest of your economists, head and shoulders above the physiocrats in penetration, clear-headedness and good sense (which are the qualities an economist should have)."
