Some fifteen years after the publication of Chambers's Cyclopædia, an Englishman (Mills) and a German (Sellius) went to Le Breton with a project for its translation into French. The bookseller obtained the requisite privilege from the government, but he obtained it for himself, and not for the projectors. This trick led to a quarrel, and before it was settled the German died and the Englishman returned to his own country. They left the translation behind them duly executed.[96] Le Breton then carried the undertaking to a certain abbé, Gua de Malves. Gua de Malves (b. 1712) seems to have been a man of a busy and ingenious mind. He was the translator of Berkeley's Hylas and Philonous, of Anson's Voyages, and of various English tracts on currency and political economy. It is said that he first suggested the idea of a cyclopædia on a fuller plan,[97] but we have no evidence of this. In any case, the project made no advance in his hands. The embarrassed bookseller next applied to Diderot, who was then much in need of work that should bring him bread. His fertile and energetic intelligence transformed the scheme. By an admirable intuition, he divined the opportunity which would be given by the encyclopædic form, of gathering up into a whole all that new thought and modern knowledge, which existed as yet in unsystematic and uninterpreted fragments. His enthusiasm fired Le Breton. It was resolved to make Chambers's work a mere starting-point for a new enterprise of far wider scope.
"The old and learned D'Aguesseau," says Michelet, "notwithstanding the pitiable, the wretched sides of his character, had two lofty sides, his reform of the laws, and a personal passion, the taste and urgent need of universality, a certain encyclopædic sense. A young man came to him one day, a man of letters living by his pen, and somewhat under a cloud for one or two hazardous books that lack of bread had driven him to write. Yet this stranger of dubious repute wrought a miracle. With bewilderment the old sage listened to him unrolling the gigantic scheme of a book that should be all books. On his lips, sciences were light and life. It was more than speech, it was creation. One would have said that he had made these sciences, and was still at work, adding, extending, fertilising, ever engendering. The effect was incredible. D'Aguesseau, a moment above himself, forgot the old man, received the infection of genius, and became great with the greatness of the other. He had faith in the young man, and protected the Encyclopædia."[98]
A fresh privilege was procured (Jan. 21, 1746), and as Le Breton's capital was insufficient for a project of this magnitude, he invited three other booksellers to join him, retaining a half share for himself, and allotting the other moiety to them. As Le Breton was not strong enough to bear the material burdens of producing a work on so gigantic a scale as was now proposed, so Diderot felt himself unequal to the task of arranging and supervising every department of a book that was to include the whole circle of the sciences. He was not skilled enough in mathematics, nor in physics, which were then for the most part mathematically conceived. For that province, he associated with himself as an editorial colleague one of the most conspicuous and active members of the philosophical party. Of this eminent man, whose relations with Diderot were for some years so intimate, it is proper that we should say something.
D'Alembert was the natural son of Madame de Tencin, by whom he had been barbarously exposed immediately after his birth. "The true ancestors of a man of genius," says Condorcet finely upon this circumstance, "are the masters who have gone before him, and his true descendants are disciples that are worthy of him." He was discovered on a November night in the year 1717, by the beadle, in a nearly dying condition on the steps of the church of St. John the Round, from which he afterwards took his Christian name. An honest woman of the common people, with that personal devotion which is less rare among the poor than among the rich, took charge of the foundling. The father, who was an officer of artillery and brother of Destouches, the author of some poor comedies, by and by advanced the small sums required to pay for the boy's schooling. D'Alembert proved a brilliant student. Unlike nearly every other member of the encyclopædic party, he was a pupil not of the Jesuits but of their rivals. The Jansenists recognised the keenness and force of their pupil, and hoped that they had discovered a new Pascal. But he was less docile than his great predecessor in their ranks. When his studies were completed, he devoted himself to geometry, for which he had a passion that nothing could extinguish. For the old monastic vow of poverty, chastity, and obedience, he adopted the manlier substitute of poverty, truth, and liberty—the worthy device of every man of letters. When he awoke in the morning, he thought with delight of the work that had been begun the previous day and would occupy the day before him. In the necessary intervals of his meditations, he recalled the lively pleasure that he felt at the play: at the play between the acts, he thought of the still greater pleasure that was promised to him by the work of the morrow. His mathematical labours led to valuable results in the principles of equilibrium and the movement of fluids, in a new calculus, and in a new solution of the problem of the precession of the equinoxes.[99]
These contributions to what was then the most popular of the sciences brought him fame, and fame brought him its usual distractions. As soon as a writer has shown himself the possessor of gifts that may be of value to society, then society straightway sets to work to seduce and hinder him from diligently exercising them. D'Alembert resisted these influences steadfastly. His means were very limited, yet he could never be induced to increase them at the cost either of his social independence or of his scientific pursuits. He lived for forty years under the humble roof of the poor woman who had treated him as a son. "You will never be anything better than a philosopher," she used to cry reproachfully, "and what is a philosopher? 'Tis a madman who torments himself all his life, that people may talk about him when he is dead." D'Alembert zealously adhered to his destination. Frederick the Great vainly tempted him by an offer of the succession to Maupertuis as president of the Academy of Berlin. Although, however, he declined to accept the post, he enjoyed all its authority and prerogative. Frederick always consulted him in filling up vacancies and making appointments. It is a magnanimous trait in D'Alembert's history that he should have procured for Lagrange a position and livelihood at Berlin, warmly commending him as a man of rare and superior genius, although Lagrange had vigorously opposed some of his own mathematical theories. Ten years after Frederick's offer, the other great potentate of the north, Catherine of Russia, besought him to undertake the education of the young grand duke, her son. But neither urgent flatteries and solicitations under the imperial hand, nor the munificent offer of a hundred thousand francs a year, availed to draw him away from his independence and his friends. The great Frederick used to compare him to one of those oriental monarchs, who cherish a strict seclusion in order to enhance their importance and majesty. He did not refuse a pension of some fifty pounds a year from Berlin, and the same amount was bestowed upon him from the privy purse at Versailles. He received a small annual sum in addition from the Academy.
Though the mathematical sciences remained the objects of his special study, D'Alembert was as free as the other great men of the encyclopædic school from the narrowness of the pure specialist. He naturally reminds us of the remarkable saying imputed to Leibnitz, that he only attributed importance to science, because it enabled him to speak with authority in philosophy and religion. His correspondence with Voltaire, extending over the third quarter of the century, is the most instructive record that we possess of the many-sided doings of that busy time. His series of éloges on the academicians who died between 1700 and 1772 is one of the most interesting works in the department of literary history. He paid the keenest attention to the great and difficult art of writing. Translations from Tacitus, Bacon, and Addison, show his industry in a useful practice. A long collection of synonyms bears witness to his fine discrimination in the use of words. And the clearness, precision, and reserved energy of his own prose mark the success of the pains that he took with style. He knew the secret. Have lofty sentiments, he said, and your manner of writing will be firm and noble.[100] Yet he did not ignore the other side and half of the truth, which is expressed in the saying of another important writer of that day—By taking trouble to speak with precision, one gains the habit of thinking rightly (Condillac).
Like so many others to whom literature owes much, D'Alembert was all his life fighting against bad health. Like Voltaire and Rousseau, he was born dying, and he remained delicate and valetudinarian to the end. He had the mental infirmities belonging to his temperament. He was restless, impatient, mobile, susceptible of irritation. When the young Mademoiselle Phlipon, in after years famous as wife of the virtuous Roland, was taken to a sitting of the Academy, she was curious to see the author of the Preliminary Discourse to the Encyclopædia, but his small face and sharp thin voice made her reflect with some disappointment, that the writings of a philosopher are better to know than his mask.[101] In everything except zeal for light and emancipation, D'Alembert was the opposite of Diderot. Where Diderot was exuberant, prodigal, and disordered, D'Alembert was a precisian. Difference of temperament, however, did not prevent their friendship from being for many years cordial and intimate. When the Encyclopædia was planned, it was to D'Alembert, as we have said, that Diderot turned for aid in the mathematical sciences, where his own knowledge was not sufficiently full nor well grounded. They were in strong and singular agreement in their idea of the proper place and function of the man of letters. One of the most striking facts about their alliance, and one of the most important facts in the history of the Encyclopædia, is that henceforth the profession of letters became at once definite and independent. Diderot and D'Alembert both of them remained poor, but they were never hangers-on. They did not look to patrons, nor did they bound their vision by Versailles. They were the first to assert the lawful authority of the new priesthood. They revolted deliberately and in set form against the old system of suitorship and protection. "Happy are men of letters," wrote D'Alembert, "if they recognise at last that the surest way of making themselves respectable is to live united and almost shut up among themselves; that by this union they will come, without any trouble, to give the law to the rest of the nation in all affairs of taste and philosophy; that the true esteem is that which is awarded by men who are themselves worthy of esteem.... As if the art of instructing and enlightening men were not, after the too rare art of good government, the noblest portion and gift in human reach."[102]
This consciousness of the power and exaltation of their calling, which men of letters now acquired, is much more than the superficial fact which it may at first seem to be. It marked the rise of a new teaching order and the supersession of the old. The highest moral ideas now belonged no longer to the clergy, but to the writers; no longer to official Catholicism, but to that fertilising medley of new notions about human knowledge and human society which then went by the name of philosophy. What is striking is that the ideas sown by philosophy became eventually the source of higher life in Catholicism. If the church of the revolution showed something that we may justly admire, it was because the encyclopædic band had involuntarily and inevitably imparted a measure of their own clearsightedness, fortitude, moral energy, and spirit of social improvement, to a church which was, when they began their work, an abominable burden on the spiritual life of the nation. If the Catholicism of Chateaubriand, of Lamennais, of Montalembert, was a different thing from the Catholicism of a Dubois, or a Rohan, from the vile corruptions of the Jesuits and the grovelling superstitions of the later Jansenists, it was the execrated freethinkers whom the church and mankind had to thank for the change. The most enlightened Catholic of to-day ought to admit that Voltaire, Diderot, Rousseau, were the true reformers of his creed. They supplied it with ideas which saved it from becoming finally a curse to civilisation. It was no Christian prelate, but Diderot who burst the bonds of a paralysing dogma by the magnificent cry, Détruisez ces enceintes qui rétrécissent vos idées! Elargissez Dieu![103] We see the same phenomenon in our own day. The Christian churches are assimilating as rapidly as their formula will permit, the new light and the more generous moral ideas and the higher spirituality of teachers who have abandoned all churches, and who are systematically denounced as enemies of the souls of men. Sic vos non vobis mellificatis apes! These transformations of religion by leavening elements contributed from a foreign doctrine, are the most interesting process in the history of truth.
The Encyclopædia became a powerful engine for aiding such a transformation. Because it was this, and because it rallied all that was then best in France round the standard of light and social hope, we ought hardly to grudge time or pains to its history. For it was not merely in the field of religious ideas that the Encyclopædists led France in a new way. They affected the national life on every side, pressing forward with enlightened principles in all the branches of material and political organisation. Their union in a great philosophical band gave an impressive significance to their work. The collection within a single set of volumes of a body of new truths, relating to so many of the main interests of men, invested the book and its writers with an aspect of universality, of collective and organic doctrine, which the writers themselves would without doubt have disowned, and which it is easy to dissolve by tests of logic. But the popular impression that the Encyclopædists constituted a single body with a common doctrine and a common aim was practically sound. Comte has pointed out with admirable clearness the merit of the conception of an encyclopædic workshop.[104] It united the members of rival destructive schools in a great constructive task. It furnished a rallying-point for efforts otherwise the most divergent. Their influence was precisely what it would have been, if popular impressions had been literally true. Diderot and D'Alembert did their best to heighten this feeling. They missed no occasion of fixing a sentiment of co-operation and fellowship. They spoke of their dictionary as the transactions of an Academy.[105] Each writer was answerable for his own contribution, but he was in the position of a member of some learned corporation. To every volume, until the great crisis of 1759, was prefixed a list of those who had contributed to it. If a colleague died, the public was informed of the loss that the work had sustained, and his services were worthily commemorated in a formal éloge.[106] Feuds, epigrams, and offences were not absent, but on the whole there was steadfast and generous fraternity.
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.
