Again, though Diderot himself is not ungenerously handled in the Confessions, there are passages about Madame d’Epinay and Madame d’Houdetot which not only stamp Rousseau with ingratitude towards two women who had treated him kindly, but which were calculated to make practical mischief among people still living. All this was atrocious in itself, and the atrocity seemed more black to Diderot than to others, because he had for some years known Madame d’Epinay as a friendly creature, and, above all, because Grimm was her lover. Perhaps we may add among the reasons that stirred him to pen these diatribes, a consciousness of the harm that Rousseau’s sentimentalism had done to sound and positive thinking. But this, we may be sure, would be infinitely less potent than the motives that sprang from Diderot’s own sentimentalism. The quarrel, for all save a few foolish partisans, is now dead, and we may leave the dust once more to settle thick upon it. Diderot’s own way of reading history is not unworthy of imitation, and it is capable of application in spirit to private conduct no less than to the history of great public events. “Does the narrative present me with some fact that dishonours humanity? Then I examine it with the most rigorous severity; whatever sagacity I may be able to command, I employ in detecting contradictions that throw suspicion on the story. It is not so when an action is beautiful, lofty, noble. Then I never think of arguing against the pleasure that I feel in sharing the name of man with one who has done such an action. I will say more; it is to my heart, and perhaps too it is only conformable to justice, to hazard an opinion that tends to whiten an illustrious personage, in the face of authorities that seem to contradict the tenour of his life, of his doctrine, and of his general repute.”[186]
The elaborate outbreak against Rousseau is perhaps Diderot’s only breach of what ought thus to be a rule for all magnanimous men. Diderot, or his shade, paid the penalty. La Harpe retaliated for some slight wound to pitiful literary vanity, by a lecture on Seneca in which he raked up all the old accusations against Seneca’s champion. La Harpe, for various reasons into which we need not now more particularly enter, got the ear of the European public in the years of reaction after he had himself deserted his old philosophic friends, and gone over to the conservative camp. He found the world eager to listen to all that could be said against men who were believed to have corrupted their age; and his bitter misrepresentations, not seldom invigorated by lies, were the origin of much of the vulgar prejudice that has only begun to melt away in our own generation.
Rousseau died in 1778. The more versatile literary genius of the century had died a couple of months earlier in the same year. It was not until the occasion of Voltaire’s triumphant visit to Paris, after an absence of seven-and-twenty years, that he and Diderot at length met. Their correspondence had been less constant and less cordial than was common where Voltaire was concerned; but though their sympathy was imperfect, there was no lack of mutual goodwill and admiration. The poet is said to have done his best to push Diderot into the Academy, but the king was incurably hostile, and Diderot was not anxious for an empty distinction. He had none of that vanity nor eagerness for recognition—pardonable enough, for that matter—which such distinctions gratify. And he perhaps agreed with Voltaire himself, who said of academies and parliaments that, when men come together, their ears instantly become elongated. After Diderot’s return from Russia Voltaire wrote to him: “I am eighty-three years of age, and I repeat that I am inconsolable at the thought of dying without ever having seen you. I have tried to collect around me as many of your children as possible, but I am a long way from having the whole family.... We are not so far apart, at bottom, and it only needs a conversation to bring us to an understanding.”[187]
Of such conversations we have almost nothing to tell. No sacred bard has commemorated the salutation of the heroes. We only know that at the end of their first interview Diderot’s facility of discourse had been so copious that, after he had taken his leave, Voltaire said: “The man is clever, assuredly; but he lacks one talent, and an essential talent—that of dialogue.” Diderot’s remark about Voltaire was more picturesque. “He is like one of those old haunted castles, which are falling into ruins in every part; but you easily perceive that it is inhabited by some ancient sorcerer.”[188] They had a dispute as to the merits of Shakespeare, and Diderot displeased the patriarch by repeating the expression that we have already quoted (vol. i. p. 330) about Shakespeare being like the statue of St. Christopher at Notre Dame, unshapely and rude, but such a giant that ordinary men could pass between his legs without touching him.[189]
There was one man who might have told us a thousand interesting things both about Diderot’s conversations with Voltaire, and his relations with other men. This man was Naigeon, to whom Diderot gave most of his papers, and who always professed, down to his death in 1814, to be Diderot’s closest adherent and most authoritative expounder. Diderot was, as he always knew and said, less an author than a talker; not a talker like Johnson, but like Coleridge. If Naigeon could only have contented himself with playing reporter, and could have been blessed by nature with the rare art of Boswell. “We wanted,” as Carlyle says, “to see and know how it stood with the bodily man, the working and warfaring Denis Diderot; how he looked and lived, what he did, what he said.” Instead of which, nothing but “a dull, sulky, snuffling, droning, interminable lecture on Atheistic Philosophy,” delivered with the vehemence of some pulpit-drumming Gowkthrapple, or “precious Mr. Jabesh Rentowel.” Naigeon belonged to the too numerous class of men and women overabundantly endowed with unwise intellect. He was acute, diligent, and tenacious; fond of books, especially when they had handsome margins and fine bindings; above all things, he was the most fanatical atheist, and the most indefatigable propagandist and eager proselytiser which that form of religion can boast. We do not know the date of his first acquaintance with Diderot;[190] we only know that at the end of Diderot’s days he had no busier or more fervent disciple than Naigeon. To us, at all events, whatever it may have been to Diderot, the acquaintance and discipleship have proved good for very little.
Our last authentic glimpse of Diderot is from the pen of a humane and enlightened Englishman, whose memory must be held in perpetual honour among us. Samuel Romilly, then a young man of four-and-twenty, visited Paris in 1781. He made the acquaintance of the namesake who had written the articles on watch-making in the Encyclopædia, and whose son had written the more famous articles on Toleration and Virtue. By this honest man Romilly was introduced to D’Alembert and Diderot. The former was in weak health and said very little. Diderot, on the contrary, was all warmth and eagerness, and talked to his visitor with as little reserve as if he had been long and intimately acquainted with him. He spoke on politics, religion, and philosophy. He praised the English for having led the way to sound philosophy, but the adventurous genius of the French, he said, had pushed them on before their guides. “You others,” he continued, “mix up theology with your philosophy; that is to spoil everything, it is to mix up lies with truth; il faut sabrer la théologie—we must put theology to the sword.” He was ostentatious, Romilly says, of a total disbelief in the existence of a God. He quoted Plato, “the author of all the good theology that ever existed in the world, as saying that there is a vast curtain drawn over the heavens, and that men must content themselves with what passes beneath that curtain, without ever attempting to raise it; and in order to complete my conversion from my unhappy errors, he read me all through a little work of his own”—of which we shall presently speak. On politics he talked very eagerly, “and inveighed with great warmth against the tyranny of the French government. He told me that he had long meditated a work upon the death of Charles the First; that he had studied the trial of that prince; and that his intention was to have tried him over again, and to have sent him to the scaffold if he had found him guilty, but that he had at last relinquished the design. In England he would have executed it, but he had not the courage to do so in France. D’Alembert, as I have observed was more cautious; he contented himself with observing what an effect philosophy had in his own time produced on the minds of the people. The birth of the Dauphin (known afterwards as Lewis XVII., the unhappy prisoner of the Temple) afforded him an example. He was old enough, he said, to remember when such an event had made the whole nation drunk with joy (1729), but now they regarded with great indifference the birth of another master.”[191]
It was thus clear to the two veterans of the Encyclopædia that the change for which they had worked was at hand. The press literally teemed with pamphlets, treatises, poems, histories, all shouting from the house-tops open destruction to beliefs which fifty years before were actively protected against so much as a whisper in the closet. Every form of literary art was seized and turned into an instrument in the remorseless attack on L’Infâme. The conservative or religious opposition showed a weakness that is hardly paralleled in the long history of the mighty controversy. Ability, adroitness, vigour, and character were for once all on one side. Palissot was perhaps, after all, the best of the writers on the conservative side.[192] With all his faults, he had the literary sense. Some of what he said was true, and some of the third-rate people whom he assailed deserved the assault. His criticism on Diderot’s drama, The Natural Son, was not a whit more severe than that bad play demanded.[193] Not seldom in the course of this work we have wished with Palissot that the excellent Diderot were less addicted to prophetic and apocalyptical turns of speech, that there were less of chaos round his points of burning and shining light, and that he had less title to the hostile name of the Lycophron of philosophy.[194] But the comedy of The Philosophers was a scandalous misrepresentation, introducing Diderot personally on the stage, and putting into his mouth a mixture of folly and knavery that was as foreign to Diderot as to any one else in the world. In 1782 the satirist again attacked his enemy, now grown old and weary. In Le Satyrique, Valère, a spiteful and hypocritical poetaster, is intended partially at least for Diderot. A colporteur, not ill-named as M. Pamphlet, comes to urge payment of his bill.
