As it was, neither side could be convinced by the other, for they had no common criterion. They had hardly even a common language. The only effect of Holbach’s blows was to persuade the bystanders who thronged round the lists in that eager time, that the so-called proofs with which the high philosophic names were associated, were only proofs to those who accepted a way of thinking which it was the very characteristic of that age decisively to reject. The controversial force of this part of the attack simply lay in the piercing thoroughness with which the irreconcilable discrepancies between the seventeenth century notion of demonstration, and that notion in the eighteenth, were forced upon the reader’s attention.
One other remark may be made. Whatever we may think of the success of the author’s assault on the theistic hypothesis of the universe, it is impossible to deny that he at least succeeds in repelling the various assaults levelled on what is vulgarly termed atheism. He rightly urges the unreasonableness of taxing those who have formed to themselves intelligible notions of the moving power of the universe, with denying the existence of such a power; the absurdity of charging the very men who found everything that comes to pass in the world on fixed and constant laws, with attributing everything to chance. If by Atheist, he says, you mean a man who would deny the existence of a force inherent in matter, and without which you cannot conceive nature, and if to this moving force you give the name of God, then an Atheist would be a madman. Holbach then describes the sense in which Atheists both exist and, as he thinks, may well justify their existence. Their qualities are as follows: To be guided only by experience and the testimony of their senses, and to perceive nothing in nature except matter, essentially active and mobile and capable of producing all the beings that we see; to forego all search for a chimerical cause, and not to mistake for better knowledge of the moving force of the universe, merely a separate attribution of it to a Being placed outside of the great whole; to confess in good faith that their mind can neither conceive nor reconcile the negative attributes and theological abstractions with the human and moral qualities that are ascribed to the Divinity.
The chapter (ix.) on the superiority of Naturalism over Theism as a basis for the most wholesome kind of Morality, is still worth reading by men in search of weapons against the presumptuous commonplaces of the pulpit. In this sphere Holbach is as earnest and severe as the most rigorous moralist that ever wrote. People who talk of the moral levity of the destructive literature of the eighteenth century would be astonished, if they could bring themselves to read the books about which they talk, by the elevation of the System of Nature. The writer points out the necessarily evil influence upon morals of a Book popularly taken to be inspired, in which the Divinity is represented as now prescribing virtue, but now again prescribing crime and absurdity; who is sometimes the friend, and sometimes the enemy, of the human race; who is sometimes pictured as reasonable, just, and beneficent, and at other times as insensate: unjust, capricious, and despotic. Such divinities, and the priests of such divinities, are incapable of being the models, types, and arbiters of virtue and righteousness. No; we must seek a base for morality in the necessity of things. Whatever the Cause that placed man in the abode in which he dwells, and endowed him with his faculties—whether we regard the human species as the work of Nature, or of some intelligent Being distinct from Nature—the existence of man, such as we see him to be, is a fact. We see in him a being who feels, thinks, has intelligence, has self-love, who strives to make life agreeable to himself, and who lives in society with beings like himself; beings whom by his conduct he may make his friends or his enemies. It is on these universal sentiments that you ought to base morality, which is nothing more nor less than the science of the duties of man living in society. The moment you attempt to find a base for morals outside of human nature, you go wrong; no other is solid and sure. The aid of the so-called sanctions of theology is not only needless, but mischievous. The alliance of the realities of duty with theological phantoms exposes duty to the same ruin which daylight brings to the superstition that has been associated with duty. It sets up the arbitrary demands of a varying something, named Piety, in place of the plain requirements of Right. As for saying that without God man cannot have moral sentiments, or, in other words, cannot distinguish between vice and virtue, it is as if one said that, without the idea of God, man would not feel the necessity of eating and drinking.
The writer then breaks out into a long and sustained contrast, from which we may make a short extract to illustrate the heat to which the battle had now come:
“Nature invites man to love himself, incessantly to augment the sum of his happiness: Religion orders him to love only a formidable God who is worthy of hatred; to detest and despise himself, and to sacrifice to his terrible idol the sweetest and most lawful pleasures. Nature bids man consult his reason, and take it for his guide: Religion teaches him that this reason is corrupted, that it is a faithless, truthless guide, implanted by a treacherous God, to mislead his creatures. Nature tells man to seek light, to search for the truth: Religion enjoins upon him to examine nothing, to remain in ignorance. Nature says to man: ‘Cherish glory, labour to win esteem, be active, courageous, industrious:’ Religion says to him: ‘Be humble, abject, pusillanimous, live in retreat, busy thyself in prayer, meditation, devout rites; be useless to thyself, and do nothing for others.’ Nature proposes for her model, men endowed with noble, energetic, beneficent souls, who have usefully served their fellow-citizens: Religion makes a show and a boast of the abject spirits, the pious enthusiasts, the phrenetic penitents, the vile fanatics, who for their ridiculous opinions have troubled empires.... Nature tells children to honour, to love, to hearken to their parents, to be the stay and support of their old age: Religion bids them prefer the oracle of their God, and to trample father and mother under foot, when divine interests are concerned. Nature commands the perverse man to blush for his vices, for his shameless desires, his crimes: Religion says to the most corrupt: ‘Fear to kindle the wrath of a God whom thou knowest not: but if against his laws thou hast committed crime, remember that he is easy to appease and of great mercy: go to his temple, humble thyself at the feet of his ministers, expiate thy misdeeds by sacrifices, offerings, prayers; these will wash away thy stain in the eyes of the Eternal.’”
Of course, philosophical criticism would have much to say about this glowing mass of furious propositions; for the first voice of Nature hardly whispers into the ear of the primitive man all these high and generous promptings. But if by Nature we here understand the Encyclopædists, and by Religion the Catholic Church in France at that moment, then Holbach’s fiery antitheses are a tolerably fair account of the matter. And the political side of the indictment was hardly less just, though its hardihood appalled men like Voltaire.
“Nature says to man, ‘Thou art free, and no power on earth can lawfully strip thee of thy rights:’ Religion cries to him that he is a slave condemned by God to groan under the rod of God’s representatives. Nature bids man to love the country that gave him birth, to serve it with all loyalty, to bind his interests to hers against every hand that might be raised upon her: Religion commands him to obey without a murmur the tyrants that oppress his country, to take their part against her, to chain his fellow-citizens under their lawless caprices. Yet if the Sovereign be not devoted enough to his priests, Religion instantly changes her tone; she incites the subjects to rebellion, she makes resistance a duty, she cries aloud that we must obey God rather than man.... If the nature of man were consulted on Politics, which supernatural ideas have so shamefully depraved, it would contribute far more than all the religion in the world to make communities happy, powerful, and prosperous under reasonable authority.... This nature would teach princes that they are men and not gods; that they are citizens charged by their fellow-citizens with watching over the safety of all.... Instead of attributing to the divine vengeance all the wars, the famines, the plagues that lay nations low, would it not have been more useful to show them that such calamities are due to the passions, the indolence, the tyranny of their princes, who sacrifice the nations to their hideous delirium? Natural evils demand natural remedies; ought not experience, therefore, long ago to have undeceived mortals as to those supernatural remedies, those expiations, prayers, sacrifices, fastings, processions, that all the peoples of the earth have so vainly opposed to the woes that overwhelmed them?... Let us recognise the plain truth, then, that it is these supernatural ideas that have obscured morality, corrupted politics, hindered the advance of the sciences, and extinguished happiness and peace even in the very heart of man.”
Holbach was a vigorous propagandist. Two years after the appearance of his master-work he drew up its chief propositions in a short and popular volume, called Good sense; or Natural Ideas opposed to Supernatural. His zeal led him to write and circulate a vast number of other tractates and short volumes, the bare list of which would fill several of these pages, all inciting their readers to an intellectual revolt against the reigning system in Church and State. He lived to get a glimpse of the very edge and sharp bend of the great cataract. He died in the spring of 1789. If he had only lived five years longer, he would have seen the great church of Notre Dame solemnly consecrated by legislative decree to the worship of Reason, bishops publicly trampling on crosier and ring amid universal applause, and vast crowds exulting in processions whose hero was an ass crowned with a mitre.
