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 be 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.
