 There are different ways of dividing up Diderot’s intellectual career, some which emphasize pure philosophical commitments, others focusing on particular projects or strands of his thought, and still others giving pride of place to politics. Of course, all of them acknowledge the central place of the Encyclopédie, not just because it was an enormous editorial project spanning many of the “best” years of Diderot’s productive life, but because it marked the invention of a new model of knowledge, collaborative in the literal sense as a compendium of individually authored articles, but also in the sense of joining disciplines, including the “arts and crafts,” as newly equal purveyors of theoretical knowledge along with “first philosophy”. The Encyclopédie is also an important resource if one is looking for Diderot’s sources, as he authored many long entries on Epicureanism, Hobbes, Locke, Leibniz, or rather Leibnizianism, along with texts on eclecticism, skepticism and other doctrines which reveal both his involvement with such ideas and the way he transforms them.
