““Man is born free but is everywhere in chains,” wrote Jean-Jacques Rousseau in The Social Contract in 1762. A generation of crusading lawyers put Enlightenment principles into action by helping slaves sue for the right to be treated as ordinary French subjects. They took the issue of human bondage to the sovereign parlement courts of France—and won, in nearly every case, liberty for their black and mixed-race clients. The infuriated Louis XV found his hands tied. The phrase “absolute monarchy” is misleading: Ancien Régime France was a state of laws, of ancient precedents, where the spark of enlightened reason could and occasionally did ignite great things.””
