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 in the preface to the eighth volume (1765), "we have raised a shout of joy like the sailor when he espies land after a sombre night that has kept him midway between sky and flood, it is to M. de Jaucourt that we are indebted for it. What has he not done for us, especially in these latter times? With what constancy has he not refused all the solicitations, whether of friendship or of authority, that sought to take him away from us? Never has sacrifice of repose, of health, of interest been more absolute and more entire."[116] These modest and unwearying helpers in good works ought not to be wholly forgotten, in a commemoration of more far-shining names.
Besides those who were known to the conductors of the Encyclopædia, was a host of unsought volunteers. "The further we proceed," the editors announced in the preface to the sixth volume (1756), "the more are we sensible of the increase both in matter and in number of those who are good enough to second our efforts." They received many articles on the same subject. They were constantly embarrassed by an emulation which, however flattering as a testimony to their work, obliged them to make a difficult choice, or to lose a good article, or to sacrifice one of their regular contributors, or to offend some influential newcomer. Every one who had a new idea in his head, or what he thought a new idea, sent them an article upon it. Men who were priests or pastors by profession and unbelievers in their hearts, sent them sheaves of articles in which they permitted themselves the delicious luxury of saying a little of what they thought. Women, too, pressed into the great work. Unknown ladies volunteered sprightly explanations of the technicalities of costume, from the falbala which adorned the bottom of their skirts, up to that little knot of riband in the hair, which had come to replace the old appalling edifice of ten stories high, in hierarchic succession of duchess, solitary, musketeer, crescent, firmament, tenth heaven, and mouse.[117] The oldest contributor was Lenglet du Fresnoy, whose book on the Method of Studying History is still known to those who have examined the development of men's ideas about the relations of the present to the past. Lenglet was born in 1674. The youngest of the band was Condorcet, who was born nearly seventy years later (1743). One veteran, Morellet, who had been, the schoolmate of Turgot and Loménie de Brienne, lived to think of many things more urgent than Faith, Fils de Dieu, and Fundamentals. He survived the Revolution, the Terror, the Empire, Waterloo, the Restoration, and died in 1819, within sight of the Holy Alliance and the Peterloo massacre. From the birth of Lenglet to the death of Morellet—what an arc of the circle of western experience!
No one will ask whether the keen eye, and stimulating word, and helpful hand of Voltaire were wanting to an enterprise which was to awaken men to new love of tolerance, enlightenment, charity, and justice. Voltaire was playing the refractory courtier at Potsdam when the first two volumes appeared. With characteristic vehemence, he instantly pronounced it a work which should be the glory of France, and the shame of its persecutors. Diderot and D'Alembert were raising an immortal edifice, and he would gladly furnish them with a little stone here or there, which they might find convenient to stuff into some corner or crevice in the wall. He was incessant in his industry. Unlike those feebler and more consequential spirits, the petits-maîtres of thought, by whom editors are harassed and hindered, this great writer was as willing to undertake small subjects as large ones, and to submit to all the mutilations and modifications which the exigencies of the work and the difficulties of its conductors recommended to them.[118] As the structure progresses, his enthusiasm waxes warmer. Diderot and his colleague are cutting their wings for a flight to posterity. They are Atlas and Hercules bearing a world upon their shoulders. It is the greatest work in the world; it is a superb pyramid; its printing-office is the office for the instruction of the human race; and so forth, in every phrase of stimulating sympathy and energetic interest. Nor does his sympathy blind him to faults of execution. Voltaire's good sense and sound judgment were as much at the service of his friends in warning them of shortcomings, as in eulogising what they achieved. And he had good faith enough to complain to his friends, instead of complaining of them. In one place he tells them, what is perfectly true, that their journeymen are far too declamatory, and too much addicted to substitute vague and puerile dissertations for that solid instruction which is what the reader of an Encyclopædia seeks. In another he remonstrates against certain frivolous affectations, and some of the coxcombries of literary modishness. Everywhere he recommends them to insist on a firm and distinct method in their contributors—etymologies, definitions, examples, reasons, clearness, brevity. "You are badly seconded," he writes; "there are bad soldiers in the army of a great general."[119] "I am sorry to see that the writer of the article Hell declares that hell was a point in the doctrine of Moses; now by all the devils that is not true. Why lie about it? Hell is an excellent thing, to be sure, but it is evident that Moses did not know it. 'Tis this world that is hell."[120]
D'Alembert in reply always admitted the blemishes for which the patriarch and master reproached them, but urged various pleas in extenuation. He explains that Diderot is not always the master, either to reject or to prune the articles that are offered to him.[121] A writer who happened to be useful for many excellent articles would insist as the price of good work that they should find room for his bad work also; and so forth. "No doubt we have bad articles in theology and metaphysics, but with theologians for censors, and a privilege, I defy you to make them any better. There are other articles that are less exposed to the daylight, and in them all is repaired. Time will enable people to distinguish what we have thought from what we have said."[122] This last is a bitter and humiliating word, but before any man hastens to cast a stone, let him first make sure that his own life is free from every trace of hypocritical conformity and mendacious compliance. Condorcet seems to make the only remark that is worth making, when he says that the true shame and disgrace of these dissemblings lay not with the writers, whose only other alternative was to leave the stagnation of opinion undisturbed, but with the ecclesiastics and ministers whose tyranny made dissimulation necessary. And the veil imposed by authority did not really serve any purpose of concealment. Every reader was let into the secret of the writer's true opinion of the old mysteries, by means of a piquant phrase, an adroit parallel, a significant reference, an equivocal word of dubious panegyric. Diderot openly explains this in the pages of the Encyclopædia itself. "In all cases," he says, "where a national prejudice would seem to deserve respect, the particular article ought to set it respectfully forth, with its whole procession of attractions and probabilities. But the edifice of mud ought to be overthrown and an unprofitable heap of dust scattered to the wind, by references to articles in which solid principles serve as a base for the opposite truths. This way of undeceiving men operates promptly on minds of the right stamp, and it operates infallibly and without any troublesome consequences, secretly and without disturbance, on minds of every description."[123] "Our fanatics feel the blows," cried D'Alembert complacently, "though they are sorely puzzled to tell from which side they come."[124]
It is one of the most deplorable things in the history of literature to see a man endowed with Diderot's generous conceptions and high social aims, forced to stoop to these odious economies. In reading his Prospectus, and still more directly in his article,
Encyclopédie, we are struck by the beneficence and breadth of the great designs which inspire and support him. The Encyclopædia, it has been said, was no peaceful storehouse in which scholars and thinkers of all kinds could survey the riches they had acquired; it was a gigantic siege-engine and armoury of weapons of attack.[125] This is only true in a limited sense of one part of the work, and that not the most important part. Such a judgment is only possible for one who has not studied the book itself, or else who is ignorant of the social requirements of France at the time. We shall show this presently in detail. Meanwhile it is enough to make two observations. The implements which the circumstances of the time made it necessary to use as weapons of attack, were equally fitted for the acquisition in a happier season of those treasures of thought and knowledge which are the object of disinterested research. And what is still more important, we have to observe that it was the characteristic note and signal glory of the French revolutionary school, to subordinate mere knowledge to the practical work of raising society up from the corruption and paralysis to which it had been brought by the double action of civil and ecclesiastical authority. The efforts of the Encyclopædists were not disinterested in the sense of being vague blows in the air. Their aim was not theory but practice, not literature but life. The Encyclopædists were no doubt all men of battle, and some of them were hardly more than mere partisans.
But Diderot at least had constantly in mind the great work which remained after the battle should be won. He was profoundly conscious that the mere accumulation of knowledge of the directly physical facts of the universe would take men a very short way towards reconstruction. And he struck the key-note in such admirable passages as this: "One consideration especially that we ought never to lose from sight is that, if we ever banish a man, or the thinking and contemplative being, from above the surface of the earth, this pathetic and sublime spectacle of nature becomes no more than a scene of melancholy and silence. The universe is dumb; the darkness and silence of the night take possession of it ...It is the presence of man that gives its interest to the existence of other beings; and what better object can we set before ourselves in the history of these beings, than to accept such a consideration? Why shall we not introduce man into our work in the same place which he holds in the universe? Why shall we not make him a common centre? Is there in infinite space any other point from which we can with greater advantage draw those immense lines that we propose to extend to all other points? What a vivid and softening reaction must result between man and the beings by whom he is surrounded ...Man is the single term from which we ought to set out, and to which we ought to trace all back, if we would please, interest, touch, even in the most arid reflections and the driest details. If you take away my own existence and the happiness of my fellows, of what concern to me is all the rest of nature.'[126]
In this we hear the voice of the new time, as we do in his exclamation that the perfection of an Encyclopædia is the work of centuries; centuries had to elapse before the foundations could be laid; centuries would have to elapse before its completion: "mais à la posérité, et À L'ÊTRE QUI NE MEURT POINT!"[127] These exalted ideas were not a substitute for arduous labour. In all that Diderot writes upon his magnificent undertaking, we are struck by his singular union of common sense with elevation, of simplicity with grasp, of suppleness with strength, of modesty with hopeful confidence. On occasions that would have tempted a man of less sincerity and less seriousness to bombast and inflation, his sense of the unavoidable imperfections of so vast a work always makes itself felt through his pride in its lofty aim and beneficent design. The weight of the burden steadied him, and the anxiety of the honest and laborious craftsman mastered the impulses of rhetoric.
