Diderot and D’Alembert Encyclopédie

The Peel library holds a first edition set of the Encyclopédie, ou Dictionnaire raisonné des sciences, des arts, et des métiers (in English, Encyclopedia, or Classified Dictionary of Sciences, Art, and Trades), an eighteenth-century French encyclopedia and one of the principal works of the Age of Enlightenment. Edited by Denis Diderot (1713–1784) and Jean Le Rond D’Alembert (1717–1783), the Encyclopédie consists of seventeen volumes, which were published gradually between 1751 and 1772, with an additional eleven volumes of plates. The Encyclopédie was the first general encyclopedia to include contributions from many writers. These contributers, known as the Philosophes or the Encyclopédistes, were men dedicated to the advancement of science and secular thought. They included Montesquieu, Rousseau, and Voltaire, among others. The Encyclopédie sought to bring all the world’s knowledge together, including “useful knowledge” applicable to everyday life, so that it could be disseminated to the general public and to future generations. At the time of its release, the Encyclopédie was controversial: it was opposed by government officials and suppressed by the French Council. However, the Encyclopédie was widely influential and is now regarded as an intellectual prologue to the French Revolution. The Encyclopédie’s content is notable for its attitude of religious tolerance and liberalism, its taxonomy of human knowledge, and its innovative coverage of the trades and mechanical arts. Access an online version in the original French (including scans of images) here, or visit the University of Michigan Library's “Encyclopédie Collaborative Translation Project” to view some English-translation articles here.
