Jacques André, a French encyclopaedist, was born at Paris in 1738. After acquiring some knowledge of philosophy and of the exact sciences, he was introduced into the famous society of atheists and deists that gathered round Diderot and Baron d'Holbach. Henceforth Naigeon was the aping pupil and devoted worshipper of Diderot. He spoke and wrote nothing which he had not received in responses from the mouth of his oracle. He even assumed the gestures and voice of his great model. This slavish disposition prevented his common-place intellect from rising above the offices of editor, translator, and compiler. Besides his editions of Fontaine, Racine, and Montaigne, and other standard works, he published the works of Diderot, accompanied with an indifferent and unsatisfactory memoir of that author. He also edited many philosophical rhapsodies which their writers themselves, through very shame, had not avowed. His encyclopedic contributions, the chief of which is his "Dictionary of Philosophy, Ancient and Modern," in the Encyclopédie Méthodique, scarcely deserve to be called anything else than compilations. Naigeon died at Paris in 1810.
