Condorcet, "Éloge de d'Alembert," in Œuvres complètes de d'Alembert ( Paris, 1821), I, ix, read at the Académie des Sciences and pub- lished in 1784. Condorcet ( 1743-1794), a fellow mathematician and per- sonal friend of d'Alembert, modeled his Esquisse d'un tableau historique des progrès de l'esprit humain in part after the Preliminary Discourse. The Esquisse, written in 1793 while Condorcet was in hiding from the Terror, was the most impassioned statement of faith in progress of the Enlightenment. Voltaire, although he apparently did not immediately recognize the merit of the Discourse, later excessively rated it superior to what he called the "method" of Descartes ( Lettres sur Rabelais [ 1767], in Œuvres, ed. L. Moland [ Paris, 1879 ], XXVI, 513), and in this he was sec- onded by the nineteenth-century scholar, F. Picavet, who placed the Pre- liminary Discourse on an equal plane with the Discourse on Method ( 1637) in the introduction to the last French edition of d'Alembert Discourse ( Paris, 1894), p. 1viii. Among the i-philosophes of the eighteenth cen- tury who nonetheless praised certain features of the work was even the bitterly hostile Father Jesuit Berthier, editor of the Journal de Trévoux, October, 1751, pp. 2270 ff., and October, 1759, p. 2565. The abbé Sabatier de Castres, who consistently attacked the encyclopedists in his Trois siècles de la littérature françoise ( Paris, 1774), I, 40, regrets that the magnificent promise of the Discourse was not fulfilled in the Encyclopedia itself. In his Philosophie du dix-huitéme siécles ( Paris, 1818), I, 109-10, J. F. La Harpe, similarly an enemy of the philosophes, although he claimed to be a friend of d'Alembert, put him on a level with Pascal as a scientist and writer, because of the excellence of the Preliminary Discourse. | -x- | |
