This same hedonistic ethics was also crucial to the development of liberal political economy during the Enlightenment, and Voltaire applied his own libertinism toward this project as well. In the wake of the scandals triggered by Mandeville’s famous argument in The Fable of the Bees (a poem, it should be remembered) that the pursuit of private vice, namely greed, leads to public benefits, namely economic prosperity, a French debate about the value of luxury as a moral good erupted that drew Voltaire’s pen. In the 1730s, he drafted a poem called Le Mondain that celebrated hedonistic worldly living as a positive force for society, and not as the corrupting element that traditional Christian morality held it to be. In his Essay sur les moeurs he also joined with other Enlightenment historians in celebrating the role of material acquisition and commerce in advancing the progress of civilization. Adam Smith would famously make similar arguments in his founding tract of Enlightenment liberalism, On the Wealth of Nations, published in 1776. Voltaire was certainly no great contributor to the political economic science that Smith practiced, but he did contribute to the wider philosophical campaigns that made the concepts of liberty and hedonistic morality central to their work both widely known and more generally accepted.
