No book has ever produced a more widespread shock. Everybody insisted on reading it, and almost everybody was terrified. It suddenly revealed to men, like the blaze of lightning to one faring through darkness, the formidable shapes, the unfamiliar sky, the sinister landscape, into which the wanderings of the last fifty years had brought them unsuspecting. They had had half a century of such sharp intellectual delight as had not been known throughout any great society in Europe since the death of Michael Angelo, and had perhaps north of the Alps never been known at all. And now it seemed to many of them, as they turned over the pages of Holbach’s book, as if they stood face to face with the devil of the mediæval legend, come to claim their souls. Satire of Job and David, banter about Joshua’s massacres and Solomon’s concubines, invective against blind pastors of blinder flocks, zeal to place Newton on the throne of Descartes and Locke upon the pedestal of Malebranche, wishes that the last Jansenist might be strangled in the bowels of the last Jesuit—all this had given zest and savour to life. In the midst of their high feast, Holbach pointed to the finger of their own divinity, Reason, writing on the wall the appalling judgments that there is no God; that the universe is only matter in spontaneous movement; and, most grievous word of all, that what men call their souls die with the death of the body, as music dies when the strings are broken.

Galiani, the witty Neapolitan, who had so many good friends in the philosophic circle, anticipated the well-known phrase of a writer of our own day. “The author of the System of Nature,” he said, “is the Abbé Terrai of metaphysics: he makes deductions, suspensions of payment, and causes the very Bankruptcy of knowledge, of pleasure, and of the human mind. But you will tell me that, after all, there were too many rotten securities; that the account was too heavily overdrawn; that there was too much worthless paper on the market. That is true, too, and that is why the crisis has come.”[138] Goethe, then a student at Strasburg, has told us what horror and alarm the System of Nature brought into the circle there. “But we could not conceive,” he says, “how such a book could be dangerous. It came to us so gray, so Cimmerian, so corpse-like, that we could hardly endure its presence; we shuddered before it as if it had been a spectre. It struck us as the very quintessence of musty age, savourless, repugnant.”[139]

If this was the light in which the book appeared to the young man who was soon to be the centre of German literature, the brilliant veteran who had for two generations been the centre of the literature of France was both shocked by the audacity of the new treatise, and alarmed at the peril in which it involved the whole Encyclopædic brotherhood, with the Patriarch at their head. Voltaire had no sooner read the System of Nature than he at once snatched up his ever-ready pen and plunged into refutation.[140] At the same time he took care that the right persons should hear what he had done. He wrote to his old patron and friend Richelieu, that it would be a great kindness if he would let the King know that the abused Voltaire had written an answer to the book that all the world was talking about. I think, he says, that it is always a good thing to uphold the doctrine of the existence of a God who punishes and rewards; society has need of such an opinion. There is a curious disinterestedness in the notion of Lewis the Fifteenth and Richelieu, two of the wickedest men of their time, being anxious for the demonstration of a Dieu vengeur. Voltaire at least had a very keen sense of the meaning of a court that rewarded and punished. The author of the System of Nature, he wrote to Grimm, ought to have felt that he was undoing his friends, and making them hateful in the eyes of the king and the court.[141] This came true in the case of the great philosopher-king himself. Frederick of Prussia was offended by a book which spared political superstitions as little as theological dogma, and treated kings as boldly as it treated priests. Though keenly occupied in watching the war then waging between Russia and Turkey, and already revolving the partition of Poland, he found time to compose a defence of theism. ’Tis a good sign, Voltaire said to him, when a king and a plain man think alike: their interests are often so hostile, that when their ideas do agree, they must certainly be right.[142]

The philosophic meaning of Holbach’s propositions was never really seized by Voltaire. He is, as has been justly said, the representative of ordinary common sense which, with all its declamations and its appeals to the feelings, is wholly without weight or significance as against a philosophic way of considering things, however humble the philosophy may be.[143] He hardly took more pains to understand Holbach than Johnson took to understand Berkeley. In truth it was a characteristic of Voltaire always to take the social, rather than the philosophic view of the great issues of the theistic controversy. One day, when present at a discussion as to the existence of a deity, in which the negative was being defended with much vivacity, he astonished the company by ordering the servants to leave the room, and then proceeding to lock the door. “Gentlemen,” he explained, “I do not wish my valet to cut my throat to-morrow morning.” It was not the truth of the theistic belief in itself that Voltaire prized, but its supposed utility as an assistant to the police. D’Alembert, on the other hand, viewed the dispute as a matter of disinterested speculation. “As for the existence of a supreme intelligence,” he wrote to Frederick the Great, “I think that those who deny it advance far more than they can prove, and scepticism is the only reasonable course.” He goes on to say, however, that experience invincibly proves both the materiality of the soul, and a material deity—like that which Mr. Mill did not repudiate—of limited powers, and dependent on fixed conditions.[144]

Let us now turn to the book itself. And first, as to its author. The reader of the New Heloïsa will remember that the heroine, after her repentance and her marriage, has only one chagrin in the world; that is the blank disbelief of her husband in the two great mysteries of a Supreme Being and another world. Wolmar, the husband, has always been supposed to stand for Rousseau’s version of Holbach, and Holbach would hardly have complained of the portrait. The Wolmar of the novel is benevolent, active, patient, tranquil, friendly, and trustful. The nicely combined conjunction of the play of circumstance with the action of men pleases him, just as the fine symmetry of a statue or the skilful contrivance of dramatic effects would please him. If he has any dominant passion, it is a passion for observation; he delights in reading the hearts of men.[145]

All this seems to have been as true of the real Holbach as of the imaginary Wolmar. We have already seen him as the intimate friend and constant host of Diderot. He was one of the best-informed men of his time (1723-89). He had an excellent library, a collection of pictures, and a valuable cabinet of natural history; and his poorer friends were as freely welcome to the use of all of them as the richest. His manners were cheerful, courteous, and easy; he was a model of simplicity, and kindliness was written on every feature. His hospitality won him the well-known nickname of the maître d’hôtel of philosophy, and his house was jestingly called the Café de l’Europe. On Sundays and Thursdays, without prejudice to other days, from ten to a score of men of letters and eminent foreign visitors, including Hume, Wilkes, Shelburne, Garrick, Franklin, Priestley, used to gather round his good dishes and excellent wine. It was noted, as a mark of the attractiveness of the company, that the guests, who came at two in the afternoon, constantly remained until as late as seven and eight in the evening. To one of those guests, who afterwards became the powerful enemy of the Encyclopædic group, the gaiety, the irreverence, the hardihood of speculation and audacity of discourse, were all as gall and wormwood. Rousseau found their atheistic sallies offensive beyond endurance. Their hard rationalism was odious to the great emotional dreamer, and after he had quarrelled with them all, he transformed his own impressions of the dreariness of atheism into the passionate complaint of Julie. “Conceive the torment of living in retirement with the man who shares our existence, and yet cannot share the hope that makes existence dear; of never being able with him either to bless the works of God, or to speak of the happy future that is promised us by the goodness of God; of seeing him, while doing good on every side, still insensible to everything that makes the delight of doing good; of watching him, by the most bizarre of contradictions, think with the impious, and yet live like a Christian. Think of Julie walking with her husband; the one admiring in the rich and splendid robe of the earth the handiwork and the bounteous gifts of the author of the universe; the other seeing nothing in it all save a fortuitous combination, the product of blind force! Alas! she cries, the great spectacle of nature, for us so glorious, so animated, is dead in the eyes of the unhappy Wolmar, and in that great harmony of being where all speaks of God in accents so mild and so persuasive, he only perceives eternal silence.”[146]

Yet it is fair to the author of this most eloquent Ignoratio Elenchi, to notice that he honestly fulfilled the object with which he professed to set out—namely, to show to both the religious and philosophical parties that their adversaries were capable of leading upright, useful, and magnanimous lives. Whether he would have painted the imaginary Wolmar so favourably if he could have foreseen what kind of book the real Holbach had in his desk, is perhaps doubtful. For Holbach’s opinions looked more formidable and sombre in the cold deliberateness of print than they had sounded amid the interruptions of lively discourse.


It is needless to say, to begin with, that the writer has the most marked of the philosophic defects of the school of the century. Perhaps we might put it more broadly, and call the disregard of historic opinion the natural defect of all materialistic speculation from Epicurus downwards.[147] Like all others of his school, Holbach has no perception nor sense of the necessity of an explanation how the mental world came to be what it is, nor how men came to think and believe what they do think and believe. He gives them what he deems unanswerable reasons for changing their convictions, but he never dreams of asking himself in what elements of human character the older convictions had their root, and from what fitness for the conduct of life they drew the current of their sap. Yet unless this aspect of things had been well considered, his unanswerable reasons were sure to fall wide of the mark. Opinions, as men began to remember, after social movement had thrown the logical century into discredit, have a history as well as a logic. They are bound up with a hundred transmitted prepossessions, and they have become identified with a hundred social customs that are the most dearly cherished parts of men’s lives. Nature had as much to do with the darkness of yesterday as with the light of to-day; she is as much the accomplice of superstition as she is the oracle of reason. It was because they forgot all this that Holbach’s school now seem so shallow and superficial. The whole past was one long working of the mystery of iniquity. “The sum of the woes of the human race was not diminished—on the contrary, it was increased by its religions, by its governments, by its opinions, in a word, by all the institutions that it was led to adopt on the plea of ameliorating its lot.”[148] On lui fit adopter! But who were the on, and how did they work? With what instruments and what fulcrum? Never was the convenience of this famous abstract substantive more fatally abused. And if religion, government, and opinion had all aggravated the miseries of the human race, what had lessened them? For the Encyclopædic school never attempted, as Rousseau did, to deny that the world had, as a matter of fact, advanced towards happiness. It was because the Holbachians looked on mankind as slaves held in an unaccountable bondage, which they must necessarily be eager to throw off, that their movement, after doing at the Revolution a certain amount of good in a bad way, led at last to a mischievous reaction in favour of Catholicism.

Far more immediately significant than the philosophy of the System of Nature were the violence, directness, and pertinacity of its assault upon political government. Voltaire, as has so often been noticed, had always abstained from meddling with either the theory or the practical abuses of the national administration. All his shafts had been levelled at ecclesiastical superstition. Rousseau, indeed, had begun the most famous of his political speculations by crying that man, who was born free, is now everywhere in chains. But Rousseau was vague, abstract, and sentimental. In the System of Nature we have a clear presage of the trenchant and imperious invective which, twenty years after its publication, rang in all men’s ears from the gardens of the Palais Royal and the benches of the Jacobins’ Hall. The writer has plainly made up his mind that the time has at last come for dropping all the discreet machinery of apologue and parable, and giving to his words the edge of a sharpened sword. The vague disguises of political speculation, and the mannered reservations of a Utopia or New Atlantis, are exchanged for a passionate, biting, and loudly practical indictment. All over the world men are under the yoke of masters who neglect the instruction of their people, or only seek to cheat and deceive them. The sovereigns in every part of the globe are unjust, incapable, made effeminate by luxury, corrupted by flattery, depraved by license and impunity, destitute of talent, manners, or virtue. Indifferent to their duties, which they usually know nothing about, they are scarcely concerned for a single moment of the day with the well-being of their people; their whole attention is absorbed by useless wars, or by the desire to find at each instant new means of gratifying their insatiable rapacity. The state of society is a state of war between the sovereign and all the rest of its members. In every country alike the morality of the people is wholly neglected, and the one care of the government is to render them timorous and wretched. The common man desires no more than bread; he wins it by the sweat of his brow; joyfully would he eat it, if the injustice of the government did not make it bitter in his mouth. By the insanity of governments, those who are swimming in plenty, without being any the happier for it, yet wring from the tiller of the soil the very fruits that his arms have won from it. Injustice, by reducing indigence to despair, drives it to seek in crime resources against the woes of life. An iniquitous government breeds despair in men’s souls; its vexations depopulate the land, the fields remain untilled, famine, contagion, and pestilence stalk over the earth. Then, embittered by misery, men’s minds begin to ferment and effervesce, and what inevitably follows is the overthrow of a realm.[149]
