As Voltaire eloquently said, officers of war by land and by sea, magistrates, physicians who knew nature, men of letters whose taste purified knowledge, geometers, physicists, all united in a work that was as useful as it was laborious, without any view of interest, without even seeking fame, as many of them concealed their names; finally without any common understanding and agreement, and therefore without anything of the spirit of party.[107] Turning over the pages on which the list of writers is inscribed, we find in one place or another nearly every name that has helped to make the literature of the time famous. Montesquieu, who died in the beginning of 1755, left behind him the unfinished fragment of an article on Taste, and it may be noticed in passing that our good-natured Diderot was the only man of letters who attended the remains of the illustrious writer to the grave.[108] The article itself, though no more than a fragment, has all the charms of Montesquieu's delightful style; it is serious without pedantry, graceful without levity, and is rich in observations that are precise and pointed without the vice of emphasis. The great Turgot, diligently solicitous for the success of every enterprise that promised to improve human happiness by adding to knowledge and spreading enlightenment, wrote some of the most valuable articles that the work contained, and his discussion of Endowments perhaps still remains the weightiest contribution to that important subject. Oddly enough, he was one of the very few writers who refused to sign his name to his contributions.[109] His assistance only ceased when he perceived that the scheme was being coloured by that spirit of sect, which he always counted the worst enemy of the spirit of truth.[110] Jean Jacques Rousseau, who had just won a singular reputation by his paradoxes on natural equality and the corruptions of civilisation, furnished the articles on music in the first half dozen volumes. They were not free from mistakes, but his colleagues chivalrously defended him by the plea of careless printing or indifferent copying.[111] The stately Buffon very early in the history of the Encyclopædia sent them an article upon Nature, and the editors made haste to announce to their subscribers the advent of so superb a colleague.[112] The articles on natural history, however, were left by Buffon in his usual majestic fashion to his faithful lieutenant and squire-at-arms, Daubenton. And even his own article seems not to have been printed. Before the eleventh volume appeared, terrible storms had arisen, not a few of the shipmen had parted company, and Buffon may well have been one of them. Certainly the article on Nature, as it stands, can hardly be his.
In the supplementary volumes, which appeared in 1776—ten years after the completion of the original undertaking—two new labourers came into the vineyard, whose names add fresh lustre and give still more serious value to the work. One of these was the prince of the physiologists of the eighteenth century, the great Haller, who contributed an elaborate history of those who had been his predecessors in unfolding the intricate mechanism of the human frame, and analysing its marvels of complex function. The other was the austere and generous Condorcet. Ever loyal to good causes, and resolute against despairing of the human commonwealth, he began in the pages of the Encyclopædia a career that was brilliant with good promise and high hopes, and ended in the grim hall of the Convention and a nobly tragic death amid the red storm of the Terror.
Among the lesser stars in the encyclopædic firmament are some whose names ought not to be wholly omitted. Forbonnais, one of the most instructive economic writers of the century, contributed articles to the early volumes, which were afterwards republished in his Elements of Commerce.[113] The light-hearted Marmontel wrote cheerful articles on Comedy, Eloges, Eclogues, Glory, and other matters of literature and taste. Quesnai, the eminent founder of the economic sect, dealt with two agricultural subjects, and reproduced both his theoretical paradoxes, and his admirable practical maxims, on the material prosperity of nations. Holbach, not yet author of the memorable System of Nature, compiled a vast number of the articles on chemistry and mineralogy, chiefly and avowedly from German sources, he being the only writer of the band with a mastery of a language which was at that moment hardly more essential to culture than Russian is now. The name of Duclos should not be passed over, in the list of the foremost men who helped to raise the encyclopædic monument. He was one of the shrewdest and most vigorous intelligences of the time, being in the front rank of men of the second order. His quality was coarse, but this was only the effect of a thoroughly penetrating and masculine understanding. His articles in the Encyclopædia (Déclamation des Anciens, Etiquette, etc.) are not very remarkable; but the reflections on conduct which he styled Considérations sur les Mœurs de ce Siécle (1750), though rather hard in tone, abound in an acuteness, a breadth, a soundness of perception that entitle the book to the rare distinction, among the writings of moralists and social observers, of still being worth reading. Morellet wrote upon some of the subjects of theology, and his contributions are remarkable as being the chief examples in the record of the encyclopædic body of a distinctly and deliberately historic treatment of religion. "I let people see," he wrote many years after, "that in such a collection as the Encyclopædia we ought to treat the history and experience of the dogmas and discipline of the Christian, exactly like those of the religion of Brahma or Mahomet."[114] This sage and philosophic principle enabled him to write the article, Fils de Dieu (vol. vi.), without sliding into Arian, Nestorian, Socinian, or other heretical view on that fantastic theme. We need not linger over the names of other writers, who indeed are now little more than mere shadows of names, such as La Condamine, a scientific traveller of fame and merit in his day and generation; of Du Marsais, the poverty-stricken and unlucky scholar who wrote articles on grammar; of the President Des Brosses, who was unfortunate enough to be in the right in a quarrel about money with Voltaire, and who has since been better known to readers through the fury of the provoked patriarch, than through his own meritorious contributions to the early history of civilisation.
The name of one faithful worker in the building of this new Jerusalem ought not to be omitted, though his writings were multa non multum. The Chevalier de Jaucourt (1704–1779), as his title shows, was the younger son of a noble house. He studied at Geneva, Cambridge, and Leyden, and published in 1734 a useful account of the life and writings of Leibnitz. When the Encyclopædia was projected, his services were at once secured, and he became its slave from the beginning of A to the end of Z. He wrote articles in his own special subjects of natural history and physical science, but he was always ready to lend his help in other departments, in writing, rewriting, reading, correcting, and all those other humbler necessities of editorship of which the inconsiderate reader knows little and thinks less. Jaucourt revelled in this drudgery. God made him for grinding articles, said Diderot. For six or seven years, he wrote one day, Jaucourt has been in the middle of half a dozen secretaries, reading, dictating, slaving, for thirteen or fourteen hours a day, and he is not tired of it even now. When he was told that the work must positively be brought to an end, his countenance fell, and the prospect of release from such happy bondage filled his heart with desolation.[115] "If," says Diderot
