Vom Geist der Gesetze
One particularly influential Enlightenment publication was the "" ("Encyclopedia"). Published between 1751 and 1772 in thirty-five volumes, it was compiled by Denis Diderot, Jean le Rond d'Alembert, and a team of 150 other intellectuals. The "Encyclopédie" helped in spreading the ideas of the Enlightenment across Europe and beyond. Other landmark publications of the Enlightenment included Voltaire's "Letters on the English" (1733) and "Dictionnaire philosophique" ("Philosophical Dictionary"; 1764); Hume's "A Treatise of Human Nature" (1740); Montesquieu's "The Spirit of the Laws" (1748); Rousseau's "Discourse on Inequality" (1754) and "The Social Contract" (1762); Adam Smith's "The Theory of Moral Sentiments" (1759) and "The Wealth of Nations" (1776); and Kant's "Critique of Pure Reason" (1781).
