Shortly after beginning, Diderot came up with a much more ambitious goal than a mere translation. He wanted instead to create a comprehensive work that would include the most up-to-date knowledge on the sciences, arts, and crafts. To this end, he enlisted several of the best thinkers of the era—many of whom were well-known philosophes—to write new articles for the Encyclopédie. He also wanted to make the work accessible to a wide audience rather than just for scholars.

Although Diderot and d’Alembert ended up writing the majority of the articles, contributions also came from many noted figures (especially Voltaire, as well as Rousseau and Montesquieu). By the time the Encyclopédie finally reached completion, it contained nearly 72,000 articles accompanied by numerous illustrations.

The work as a whole represents an outstanding example of Enlightenment thought: it praised science while also questioning religion, social institutions, the legal system, and more. As a result, the Catholic Church viewed it as undermining its authority and placed the Encyclopédie on its index of forbidden works. Nevertheless, it was widely read, with people often obtaining cheaper reprint editions published in Switzerland.
