Freethought Archives > Baron d'Holbach > The System of Nature


[Webmaster's note: to avoid persecution Holbach published The System of Nature under the pseudonym of J.B. Mirabaud, an actual scholar who had died ten years previously. Word of Holbach's authorship did not leak out until the 19th century.

For this reason Samuel Wilkinson, the English translator of this 1820 edition, here misattributes the System to Mirabaud - albeit noting that the work's authorship was disputed and that Mirabaud was "assisted by Baron D'Olbac" (sic) and others.]






At a time when we are on the eve of an important change in our political affairs, which must evidently lead either to the recovery and re-establishment of our liberties, or to a military despotism, those who are connected with the press ought to use every exertion to enlighten their fellow-citizens, and to assert their right of canvassing, in the most free and unrestrained manner, every subject connected with the happiness of man.

The priesthood have ever been convenient tools in the hands of tyrants, to keep the bulk of the people in a degraded servility. By the superstitious and slavish doctrines which they infuse into their minds, they prevent them from thinking for themselves and asserting their own independence. At a moment when national schools are erecting in every quarter of the country, not with a sincere desire of enlightening the rising generation, but with the insidious design of instilling into their minds the doctrines of "Church and King," in order to bolster up a little longer the present rotten, tottering, and corrupt system: at a moment, too, when thousands of fanatic preachers are traversing the country, with a view to subjugate the human mind to the baleful empire of visonary enthusiasm and sectarian bigotry to the utter extinction of every noble, manly, liberal, and philanthropic principle;—at such a moment as this, we thought that the "SYSTEM OF NATURE" could not fail to render essential service to the cause both of civil and religious liberty. No work, ancient or modern, has surpassed it, in the eloquence and sublimity of its language, or in the facility with which it treats the most abtruse and difficult subjects. It is, without exception, the boldest effort the human mind has yet produced, in the investigation of morals and theology—in the destruction of priestcraft and superstition —and in developing the sources of all those passions and prejudices which have proved so fatal to the tranquillity of the world.

The republic of letters has never produced an author whose pen was so well calculated to emancipate mankind from all those trammels with which the nurse, the schoolmaster and the priest have successively locked up their noblest faculties, before they were capable of reasoning and judging for themselves. The frightful apprehensions of the gloomy bigot, and all the appalling terrors of superstition, are here utterly annihilated, to the complete satisfaction of every unbiassed and impartial person.—These we considered as necessary observations to make, previous to any attempt at the biography of the author.

Biography may be reckoned among the most interesting of literary productions. Its intrinsic value is such, that, though capable of extraordinary embellishment from the hand of genius, yet no inferiority of execution can so degrade it, as to deprive it of utility. Whatever relates even to man in general, considered only as an aggregate of active and intelligent beings, has a strong claim upon our notice; but that which relates to our author, as distinguished from the rest of his species, moving in a more exalted sphere, and towering above them by the resplendent excellencies of his mind, seems to me to be peculiarly calculated for our contemplation, and ought to form the highest pleasure of our lives. There is a principle of curiosity implanted in us, which leads us, in an especial manner, to investigate our fellow creatures; the eager inquisitiveness with which the mechanic seeks to know the history of his fellow-workmen and the ardour with which the philosopher, the poet, or the historian hunts for details that may familiarize him with, a Descartes or a Newton, with a Milton, a Hume, or a Gibbon— spring from the same source. Their object, however, may perhaps vary; for, in the former, it may be for the sake of detraction, invidious cavil, or malice; in the latter, it is a sweet homage paid by the human heart to the memory of departed genius.

It has been repeatedly observed that the life of a scholar affords few materials for biography. This is only negatively true;—could every scholar have a Boswell, the remark would vanish; or were every scholar a Rousseau, a Gibbon, or a Cumberland it would be equally nugatory. What can present higher objects of contemplation—what can claim more forcibly our attention—where can we seek for subjects of a more precious nature, than in the elucidation of the operations of mind, the acquisition of knowledge, the gradual expansion of genius; its application, its felicities, its sorrows, its wreaths of fame, its cold, undeserved neglect? Such scenes, painted by, the artist himself, are a rich bequest to mankind: even when traced by the hand of friendship or the pencil of admiration, they possess a permanent interest in our hearts. I cannot conceive a life more worthy of public notice, more important, more interesting to human nature, than the life of a literary man, were it executed according to the ideas I have formed of it: did it exhibit a faithful delineation of the progress of intellect, from the cradle upwards; did it portray, in accurate colors, the production of what we call genius: by what accident it was first awakened; what were its first tendencies; how directed to a particular object; by what means it was nourished and unfolded; the gradual progress of its operation in the production of a work; its hopes and fears; its delights; its miseries; its inspirations; and all the thousand fleeting joys that so often invest its path but for a moment, and then fade like the dews of the morning. Let it contain too a transcript of the many nameless transports that float round the heart, that dance in the gay circle before the ardent gazing eye, when the first conception of some future effort strikes the mind; how it pictures undefined delights of fame and popular applause; how it anticipates the bright moments of invention, and dwells with prophetic ecstasy on the felicitous execution of particular parts, that already start into existence by the magic touch of a heated imagination. Let it depict the tender feelings of solitude, the breathings of midnight silence, the scenes of mimic life, of imaged trial, that often occupy the musing mind; let it be such a work, so drawn, so coloured, and who shall pronounce it inferior? Who rather will not confess that it presents a picture of human nature, where every heart may find some corresponding harmony? When, therefore, it is said, that the life of a scholar is barren, it is so only because it has never been properly delineated; because those parts only have been selected which are common, and fail to distinguish him from the common man; because we have never penetrated into his closet, or into his heart; because we have drawn him only as an outward figure, and left unnoticed that internal structure that would delight, astonish, and improve. And then, when we compare the life of such a man with the more active one of a soldier, a statesman, or a lawyer, we pronounce it insipid, uninteresting. True;—the man of study has not fought for hire—he has not slaughtered at the command of a master: he would disdain to do so. Though unaccompanied with the glaring actions of public men, which confound and dazzle by their publicity, but shrink from the estimation of moral truth, it would present a far nobler picture; yes, and a more instructive one:—the calm disciple of reason meditates in silence; he walks his road with innoxious humility; he is poor, but his mind is his treasure; he cultivates his reason, and she lifts him to the pinnacle of truth; he learns to tear away the veil of self-love, folly, pride, and prejudice, and bares the human heart to his inspection; he corrects and amends; he repairs the breaches made by passion; the proud man passes him by, and looks upon him with scorn; but he feels his own worth, that ennobling consciousness which swells in every vein, and inspires him with true pride—with manly independence: to such a man I could sooner bow in reverence, than to the haughtiest, most successful candidate for the world's ambition. But of such men, for the reason I have already mentioned, our information is scanty. While of others, who have commanded a greater share of public notoriety, venal or mistaken admiration has given more than we wished to know. Among these respected individuals of human nature, may be placed Mirabaud. Had Mirabaud been an Englishman, who doubts but that we should have possessed at least ample details of the usual subjects of biographical notice; while all that has been collected among his own countrymen, is a scanty memoir in a common dictionary. That we are doomed to remain ignorant of the life of such men, speaks a loud disgrace.—I lament it.

JOHN BAPTISTE MIRABAUD, was born at Paris in the year 1674. He prosecuted his infantile studies under the direction of his parents, and was afterwards entered a member of the Congregation of the Priests of the Oratory, where he passed several years, and produced some very bold writings, which were never intended for publication.

He was subsequently appointed tutor to the princesses of the House of Orleans, and then took the resolution of destroying the greater part of the manuscripts that he produced while a member of the Congregation; but the treachery of some of his friends, to whom he had confided his manuscripts, rendered this precaution useless, for some of his works were published during the time he remained the preceptor to his royal pupils; among which number may be reckoned his "New Liberties of Thought," a work but little calculated for gaining him friends in the purlieus of the Court of Orleans. The "Origin and Antiquity of the World," in three parts, was also published at this period, and from the publication of this work, may be dated the resolution of M. de Mirabaud to quit his office of preceptor, which he relinquished, having become more independent; he now gave himself up entirely to his philosophical studies, and produced the "System of Nature," with which he was assisted by Diderot, D'Alembert, Baron D'Olbac, and others.

The profound metaphysical knowledge displayed throughout the System of Nature, and the doctrines which are therein advanced, warrants the conclusion, that it is at once the most decisive, boldest, and most extraordinary work, that the human understanding ever had the courage to produce. The study of metaphysics his generally been considered the most terrific to the indolent mind; but the clear and perspicuous reasoning of a Mirabaud, who has united the most profound argument, with the most fascinating eloquence, charm and instruct us at the same time. But it was not, to be expected that such doctrines as are contained in the System of Nature, would he advanced without meeting with some opposition from the superficial and bigoted metaphysicians, who feel an interest in upholding a system of delusion and superstition. No! certainly not, Their interest was threatened, and their craft in danger, and the consequence was, that the Atheist or Disciple of Nature, has been abused with every scurrilous epithet, "full of sound and fury, signifying nothing."

Atheism is stigmatized with having "opened a wide door for libertinism, destroying the social and moral compact; and striking a deadly blow at religion. It is asserted that the atheist, who by his opinions has deprived himself of the hope and consolation of a future life, has no motive for the practise of virtue, or to contribute to the well being of society. Deprived of a chimera which religion every where presents him, he wanders through the cheerless gloom of scepticism, regardless of the consequences of an abandoned life. Without a God, he acknowledges no benefactor; without divine laws, he knows no rule for the conduct of life, and submits to no law but his passions. An enemy to all social order, he spurns at human laws, and breaks through every barrier opposed to his wickedness." Under such colours is an atheist painted: a short digression must be suffered to examine this picture, and to disprove the assertions so sweepingly made.

I admit that atheism strikes a deadly blow at religion; because under the cloak of religion, mankind have been oppressed in all ages; but that it encourages libertinism, or destroys the "social and moral compact," I have yet to learn. In all organized governments, men are restrained from crime and compelled to submission by laws supposed to be made for the general benefit. These laws are the effect of the first formation of society for mutual preservation. Here then is a sufficient motive for the one as well as the other, to contribute to the well-being of society. The laws of Nature are the same in effect on the atheist and the religionist. If man be led captive by his passions, and gives himself to debauchery and voluptuousness, nature will punish him with bodily infirmities and a debilitated mind. If he be intemperate, she will shorten his days and bring him to the grave with the most poignant remorse. The fatal effects of his vicious propensities will fall upon his own head. A disturber of social order will live in continual fear of the vengeance of society, and that very fear is a more dreadful punishment than the just vengeance which perhaps he escapes. It renders life burdensome, and makes a man hateful to himself. Can men have stronger motives for the practise of virtue? The atheist is in full possession of these motives, and the religionist is most completely swayed by them, whatever may be his pretensions to others derived from religion. But we are assured he has other motives; more powerful incentives, in the promise of future rewards and punishments. This, like all other chimerical doctrines, cannot be maintained if we look at the general practise of mankind. Let us trace the effects of this doctrine, or rather let us examine the actions, conduct, and character of men professing it, and we shall see how little influence it has over them. The bulk of society believe they shall answer in a future life for the deeds done in the present. Nay, I hardly think one in a hundred thousand will say they doubt it. What then is its effect? With this dreadful sentence, "Thou shalt go into everlasting punishment," continually sounded in their ears, do we not daily see the greatest enormities committed? Are not the most horrid crimes perpetrated in all parts of the world? The most vicious propensities and the most extravagant follies are almost indiscriminately gratified. Is not vice frequently triumphant, and virtue compelled to seek her own reward in retirement? The laws of society are broken by the most flagrant injustice, and the laws of nature outraged by the most shocking depravity. All this evil exists in nations believing themselves to be accountable beings after death. Where then are the beneficial effects arising, to mankind from the promulgation of this doctrine? Men who cannot be restrained from doing evil by human laws, have no dread of any other. Their whole lives and conduct confirm this. Others who live in submission to the laws of society, give themselves up to those vicious habits, (without fear of divine laws) which the law does not take cognizance of. Men, not wholly depraved, or not without the pale of society, generally respect the laws, and fear the bad opinion of others. Hence we observe, when interest or passion leads them into secret vices, they invariably play the hypocrite; and although they are aware of the denunciations of their God, whom they acknowledge is a witness to all their actions, while they preserve their fair fame they still persevere. In fact, they live as if they disbelieved in his existence; and yet the greatest criminal, the most depraved wretch, would shudder at being told there is no God. The atheist, as a man, is liable to commit the same crimes, and fall into the same vices as the believer; but because he is an atheist, is he a worse criminal than the other? In one respect, I conceive he is not so bad. He only acts in defiance of human laws,—he only offends men; the other infringes both divine and human;—he defies both God and man. Both are injurious to society and themselves, and both are actuated by the came motives.

Again we are told, that the well disposed part of mankind are rendered more virtuous, and the vicious less vicious by this doctrine. How are we to know that? If the virtuous man acts uprightly, does good to his fellow creatures, restrains his passions, and returns good for evil, experience teaches him it is his interest so to do. Those who are viciously disposed are only deterred from crime by penal laws. Societies cannot long exist, where evil has the ascendency. Without social laws, this would really be the case, notwithstanding the threats of an avenging God. If men were told they would not be answerable for the evil committed in this life to human laws, but that God would punish them after death, it is evident the human race would soon be exterminated. On the other hand, tell them their crimes will never be punished by God, or, in other words, there is no other God than NATURE, but that the laws of men will avenge the offences against society; so long as those laws are administered with justice and impartiality, so long will such society continue to improve. Hence it is evident that the system which will maintain order in society by itself, must be the best and most rational. A good government without religion would be more solid and lasting, and tend more to the preservation of mankind, than all the theocratical or ecclesiastical governments that ever the world was subject to.—Thus much for the opponents of atheism.

It has been asserted with a perverse obstinacy, by the advocates for the existence of a deity, that the SYSTEM OF NATURE was never written by the author whose name it bears.—It is granted that it was not published during his life: but that circumstance forms no reason why such a conclusion should be drawn. The persecutions which the atheists have endured, were a sufficient excuse for the work not appearing in any form during the life time of its venerable author. The Athenians sought to try Diagoras the Melian, for atheism; but he fled from Athens, and a price was offered for his head. Protagoras was banished from Athens, and his books burnt, because he ventured to assert, that he knew nothing of the gods. Stephen Dolet was burnt at Paris for atheism. Giordano Bruno was burnt by the Inquisitors in Italy. Lucilio Vanini was burnt at Thoulouse, through the kind offices of an Attorney-General. Bayle was under the necessity of fleeing to Holland. Casimio Liszynski was executed at Grodno;—and Akenhead at Edinborough. And the body of the eloquent and erudite Hume, was obliged to be watched many nights by his friends, lest it should be taken up by the fanatics, who considered him one of the greatest monsters of iniquity, because he did not happen to believe as they believed.—With these pictures of Christian persecution before his eyes, is it surprising that M. de Mirabaud should adopt the resolution of suffering the SYSTEM OF NATURE to appear as a posthumous work? That the same fate would have attended him, the most devout Christian will not undertake to deny.

However the sentiments of M. de Mirabaud may be condemned by the fanatics, all those who knew him bear the most brilliant testimony of his integrity, candour, and the soundness of his understanding; in a word, to his social virtues, and the innocence of his manners. He died universally regretted, at Paris, the twenty-fourth of June, 1760, in the eighty-sixth year of his age.

The following works, written by him at different periods, were never published:—The Life of Jesus Christ. Impartial Reflections on the Gospel. The Morality of Nature. An Abridged History of the Priesthood; Ancient and Modern. The Opinions of the Ancients concerning the Jews. A wretched mutilated edition of this last work was published at Amsterdam, in 1740, in two small volumes, under the title of Miscellaneous Dissertations.
