The reflections, as well as the facts which have preceded, will furnish a reply to those who inquire what interest man has in not admitting unintelligible systems? The tyrannies, the persecutions, the numberless outrages committed under these systems; the stupidity, the slavery, into which their ministers almost every where plunge the people; the sanguinary disputes to which they give birth; the multitude of unhappy beings with which their fatal notions fill the world; are surely abundantly sufficient to create the most powerful, the most interesting motives, to determine all sensible men, who possess the faculty of thought, to examine into the authenticity of doctrines, which cause so many serious evils to the inhabitants of the earth.

A theist, very estimable for his talents, asks, "if there can be any other cause than an evil disposition, which can make men atheists?" I reply to him, yes, there are other causes. There is the desire, a very laudable one, of having a knowledge of interesting truths; there is the powerful interest of knowing what opinions we ought to hold upon the object which is announced to us as the most important; there is the fear of deceiving ourselves upon systems which are occupied with the opinions of mankind, which do not permit he should deceive himself respecting them with impunity. But when these motives, these causes, should not subsist, is not indignation, or if they will, an evil disposition, a legitimate cause, a good and powerful motive, for closely examining the pretensions, for searching into the rights of systems, in whose name so many crimes are perpetrated? Can any man who feels, who thinks, who has any elasticity in his soul, avoid being incensed against austere theories, which are visibly the pretext, undeniably the source, of all those evils, which on every side assail the human race? Are they not these fatal systems which are at once the cause and the ostensible reason of that iron yoke that oppresses mankind; of that wretched slavery in which he lives; of that blindness which hides from him his happiness; of that superstition, which disgraces him; of those irrational customs which torment him; of those sanguinary quarrels which divide him; of all the outrages which he experiences? Must not every breast in which humanity is not extinguished, irritate itself against that theoretical speculation, which in almost every country is made to speak the language of capricious, inhuman, irrational tyrants?

To motives so natural, so substantive, we shall join those which are still more urgent, more personal to every reflecting man: namely, that benumbing terror, that incommodious fear, which must be unceasingly nourished by the idea of capricious theories, which lay man open to the most severe penalties, even for secret thoughts, over which he himself has not any controul; that dreadful anxiety arising out of inexorable systems, against which he may sin without even his own knowledge; of morose doctrines, the measure of which he can never be certain of having fulfilled; which so far from being equitable, make all the obligations lay on one side; which with the most ample means of enforcing restraint, freely permit evil, although they hold out the most excruciating punishments for the delinquents? Does it not then, embrace the best interests of humanity, become of the highest importance to the welfare of mankind, of the greatest consequence to the quiet of his existence, to verify the correctness of these systems? Can any thing be more rational than to probe to the core these astounding theories? Is it possible that any thing can be more just, than to inquire rigorously into the rights, sedulously to examine the foundations, to try by every known test, the stability of doctrines, that involve in their operations, consequences of such colossal magnitude; that embrace, in their dictatory mandates, matters of such high behest; that implicate the eternal felicity of such countless millions in the vortex of their action? Would it not be the height of folly to wear such a tremendous yoke without inquiry; to let such overwhelming notions pass current unauthenticated; to permit the soi-disant ministers of these terrific systems to establish their power, without the most ample verification of their patents of mission? Would it, I repeat, be at all wonderful, if the frightful qualities of some of these systems, as exhibited by their official expounders, whom the accredited functionaries of similar systems, do not scruple, in the face of day, to brand as impostors, should induce rational beings to drive them entirely from their hearts; to shake off such an intolerable burden of misery; to even deny the existence of such appalling doctrines, of such petrifying systems, which the superstitious themselves, whilst paying them their homage, frequently curse from the very bottom of their hearts?

The theist, however, will not fail to tell the atheist, as he calls him, that these systems are not such as superstition paints them; that the colours are coarse, too glaring, ill assorted, the perspective out of all keeping; he will then exhibit his own picture, in which the tints are certainly blended with more mellowness, the colouring of a more pleasing hue, the whole more harmonious, but the distances equally indistinct: the atheist, in reply, will say, that superstition itself, with all the absurd prejudices, all the mischievous notions to which it gives birth, are only corollaries drawn from the fallacious ideas, from those obscure principles, which the deicolist himself indulges. That his own incomprehensible system authorizes the incomprehensible absurdities, the inconceivable mysteries, with which superstition abounds; that they flow consecutively from his own premises; that when once the mind of mortals is bewildered in the dark, inextricable mazes of an ill-directed imagination, it will incessantly multiply its chimeras. To assure the repose of mankind, fundamental errors must be annihilated; that he may understand his true relations, be acquainted with his imperative duties, primary delusions must be rectified; to procure him that serenity of soul, without which there can be no substantive happiness, original fallacies must be undermined. If the systems of the superstitious be revolting, if their theories be gloomy, if their dogmas are unintelligible, those of the theist will always be contradictory; will prove fatal, when he shall be disposed to meditate upon them; will become the source of illusions, with which, sooner or later, imposture will not omit to abuse his credulity. Nature alone, with the truths she discovers, is capable of lending to the human mind that firmness which falsehood will never be able to shake; to the human heart that self-possession, against which imposture will in vain direct its attacks.

Let us again reply to those who unceasingly repeat that the interest of the passions alone conduct man to what is termed atheism: that it is the dread of future punishment that determines corrupt individuals to make the most strenuous efforts to break up a system they have reason to dread. We shall, without hesitation, agree that it is the interest of man's passions which excites him to make inquiries; without interest, no man is tempted to seek; without passion, no man will seek vigorously. The question, then, to be examined, is, if the passions and interests, which determine some thinkers to dive into the stability or the systems held forth to their adoption, are or are not legitimate? These interests have, already been exposed, from which it has been proved, that every rational man finds in his inquietudes, in his fears, reasonable motives to ascertain, whether or not it be necessary to pass his life in perpetual dread; in never ceasing agonies? Will it be said, that an unhappy being, unjustly condemned to groan in chains, has not the right of being willing to render them asunder; to take some means to liberate himself from his prison; to adopt some plan to escape from those punishments, which every instant threaten him? Will it be pretended that his passion for liberty has no legitimate foundation, that he does an injury to the companions of his misery, in withdrawing himself from the shafts of tyrannical infliction; or in furnishing, them also with means to escape from its cruel strokes? Is, then, an incredulous man, any thing more than one who has taken flight from the general prison, in which despotic superstition detains nearly all mankind? Is not an atheist, as he is called, who writes, one who has broken his fetters, who supplies to those of his associates who have sufficient courage to follow him, the means of setting themselves free from the terrors that menace them? The priests unceasingly repeat that it is pride, vanity, the desire of distinguishing himself from the generality of mankind, that determines man to incredulity. In this they are like some of those wealthy mortals, who treat all those as insolent who refuse to cringe before them. Would not every rational man have a right to ask the priest, where is thy superiority in matters of reasoning? What motives can I have to submit my reason to thy delirium? On the other hand, way it not be said to the hierarchy, that it is interest which makes them priests; that it is interest which renders them theologians; that it is for the interest of their passions, to inflate their pride, to gratify their avarice, to minister to their ambition, &c. that they attach themselves to systems, of which they alone reap the benefits? Whatever it may be, the priesthood, contented with exercising their power over the illiterate, ought to permit those men who do think, to be excused from bending the knee before their vain, illusive idols.

We also agree, that frequently the corruption of morals, a life of debauchery, a licentiousness of conduct, even levity of mind, may conduct man to incredulity; but is it not possible to be a libertine, to be irreligious, to make a parade of incredulity, without being on that account an atheist? There is unquestionably a difference between those who are led to renounce belief in unintelligible systems by dint of reasoning, and those who reject or despise superstition, only because they look upon it as a melancholy object, or an incommodious restraint. Many persons, no doubt, renounce received prejudices, through vanity or upon hearsay; these pretended strong minds have not examined any thing for themselves; they act upon the authority of others, whom they suppose to have weighed things more maturely. This kind of incredulous beings, have not, then, any distinct ideas, any substantive opinions, and are but little capacitated to reason for themselves; they are indeed hardly in a state to follow the reasoning of others. They are irreligious in the same manner as the majority of mankind are superstitious, that is to say, by credulity like the people; or through interest like the priest. A voluptuary devoted to his appetites; a debaucheé drowned in drunkenness; an ambitious mortal given up to his own schemes of aggrandizement; an intriguer surrounded by his plots; a frivolous, dissipated mortal, absorbed by his gewgaws, addicted to his puerile pursuits, buried in his filthy enjoyments; a loose woman abandoned to her irregular desires; a choice spirit of the day: are these I say, personages, actually competent to form a sound judgment of superstition, which they have never examined? Are they in a condition to maturely weigh theories that require the utmost depth of thought? Have they the capabilities to feel the force of a subtle argument; to compass the whole of a system: to embrace the various ramifications of an extended doctrine? If some feeble scintillations occasionally break in upon the cimmerian darkness of their minds; if by any accident they discover some faint glimmerings of truth amidst the tumult of their passions; if occasionally a sudden calm, suspending, for a short season, the tempest of their contending vices, permits the bandeau of their unruly desires by which they are blinded, to drop for an instant from their hoodwinked eyes, these leave on them only evanescent traces; scarcely sooner received than obliterated. Corrupt men only attack the gods when they conceive them to be the enemies to their vile passions. Arrian says, "that when men imagine the gods are in opposition to their passions, they abuse them, and overturn their altars." The Chinese, I believe, do the same. The honest man makes war against systems which he finds are inimical to virtue—injurious to his own happiness—baneful to that of his fellow mortals—contradictory to the repose, fatal to the interests of the human species. The bolder, therefore, the sentiments of the honest atheist, the more strange his ideas, the more suspicious they appear to other men, the more strictly he ought to observe his own obligations; the more scrupulously he should perform his duties; especially if he be not desirous that his morals shall calumniate his system; which duly weighed, will make the necessity of sound ethics, the certitude of morality, felt in all its force; but which every species of superstition tends to render problematical, or to corrupt.

Whenever our will is moved by concealed and complicated motives, it is extremely difficult to decide what determines it; a wicked man may be conducted to incredulity or to scepticism by those motives which he dare not avow, even to himself; in believing he seeks after truth, he may form an illusion to his mind, only to follow the interest of his passions; the fear of an avenging system will perhaps determine him to deny their existence without examination; uniformly because he feels them incommodious. Nevertheless, the passions sometimes happen to be just; a great interest carries us on to examine things more minutely; it may frequently make a discovery of the truth, even to him who seeks after it the least, or who is only desirous to be lulled to sleep, who is only solicitous to deceive himself. It is the same with a perverse man who stumbles upon truth, as it is with him, who flying from an imaginary danger, should encounter in his road a dangerous serpent, which in his haste he should destroy; he does that by accident, without design, which a man, less disturbed in his mind, would have done with premeditated deliberation.

To judge properly of things, it is necessary to be disinterested; it is requisite to have an enlightened mind, to have connected ideas to compass a great system. It belongs, in fact, only to the honest man to examine the proofs of systems—to scrutinize the principles of superstition; it belongs only to the man acquainted with nature, conversant with her ways, to embrace with intelligence the cause of the SYSTEM OF NATURE. The wicked are incapable of judging with temper; the ignorant are inadequate to reason with accuracy; the honest, the virtuous, are alone competent judges in so weighty an affair. What do I say? Is not the virtuous man, from thence in a condition to ardently desire the existence of a system that remunerates the goodness of men? If he renounces those advantages, which his virtue confers upon him the right to hope, it is, undoubtedly, because he finds them imaginary. Indeed, every man who reflects will quickly perceive, that for one timid mortal, of whom these systems restrain the feeble passions, there are millions whose voice they cannot curb, of whom, on the contrary, they excite the fury; for one that they console, there are millions whom they affright, whom they afflict; whom they make unhappy: in short, he finds, that against one inconsistent enthusiast, which these systems, which are thought so excellent, render happy, they carry discord, carnage, wretchedness into vast countries; plunge whole nations into misery; deluge them with tears.

However this may be, do not let us inquire into motives which may determine a man to embrace a system; let us rather examine the system itself; let us convince ourselves of its rectitude; if we shall find that it is founded upon truth, we shall never, be able to esteem it dangerous. It is always falsehood that is injurious to man; if error be visibly the source of his sorrows, reason is the true remedy for them; this is the panacea that can alone carry consolation to his afflictions. Do not let us farther examine the conduct of a man who presents us with a system; his ideas, as we have already said, may be extremely sound, when even his actions are highly deserving of censure. If the system of atheism cannot make him perverse, who is not so by his temperament, it cannot render him good, who does not otherwise know the motives that should conduct him to virtue. At least we have proved, that the superstitious man, when he has strong passions, when he possesses a depraved heart, finds even in his creed a thousand pretexts more than the atheist, for injuring the human species. The atheist has not, at least, the mantle of zeal to cover his vengeance; he has not the command of his priest to palliate his transports; he has not the glory of his gods to countenance his fury; the atheist does not enjoy the faculty of expiating, at the expence of a sum of money, the transgressions of his life; of availing himself of certain ceremonies, by the aid of which he may atone for the outrages he may have committed against society; he has not the advantage of being able to reconcile himself with heaven, by some easy custom; to quiet the remorse of his disturbed conscience, by an attention to outward forms: if crime has not deadened every feeling of his heart, he is obliged continually to carry within himself an inexorable judge, who unceasingly reproaches him for his odious conduct; who forces him to blush for his own folly; who compels him to hate himself; who imperiously obliges him to fear examination, to dread the resentment of others. The superstitious man, if he be wicked, gives himself up to crime, which is followed by remorse; but his superstition quickly furnishes him with the means a getting rid of it; his life is generally no more than a long series of error and grief, of sin and expiation, following each other in alternate succession; still more, he frequently, as we have seen, perpetrates crimes of greater magnitude, in order to wash away the first. Destitute of any permanent ideas on morality, he accustoms himself to look upon nothing as criminal, but that which the ministers, the official expounders of his system, forbid him to commit: he considers actions of the blackest dye as virtues, or as the means of effacing those transgressions, which are frequently held out to him as faithfully executing the duties of his creed. It is thus we have seen fanatics expiate their adulteries by the most atrocious persecutions; cleanse their souls from infamy by the most unrelenting cruelty; make atonement for unjust wars by the foulest means; qualify their usurpations by outraging every principle of virtue; in order to wash away their iniquities, bathe themselves in the blood of those superstitious victims, whose infatuation made them martyrs.

An atheist, as he is falsely called, if he has reasoned justly, if he has consulted nature, hath principles more determinate, more humane, than the superstitious; his system, whether gloomy or enthusiastic, always conducts the latter either to folly or cruelty; the imagination of the former will never be intoxicated to that degree, to make him believe that violence, injustice, persecution, or assassination are either virtuous or legitimate actions. We every day see that superstition, or the cause of heaven, as it is called, hoodwinks even those persons who on every other occasion are humane, equitable, and rational; so much so, that they make it a paramount duty to treat with determined barbarity, those men who happen to step aside from their mode of thinking. An heretic, an incredulous being, ceases to be a man, in the eyes of the superstitious. Every society, infected with the venom of bigotry, offers innumerable examples of juridical assassination, which the tribunals commit without scruple, even without remorse. Judges who are equitable on every other occasion, are no longer so when there is a question of theological opinions; in steeping their hands in the blood of their victims, they believe, on the authority of the priests, they conform themselves to the views of the Divinity. Almost every where the laws are subordinate to superstition; make themselves accomplices in its fanatical fury; they legitimate those actions most opposed to the gentle voice of humanity; they even transform into imperative duties, the most barbarous cruelties. The president Grammont relates, with a satisfaction truly worthy of a cannibal, the particulars of the punishment of Vanini, who was burned at Thoulouse, although he had disavowed the opinions with which he was accused; this president carries his demoniac prejudices so far, as to find wickedness in the piercing cries, in the dreadful howlings, which torment wrested from this unhappy victim to superstitious vengeance. Are not all these avengers of the gods miserable men, blinded by their piety, who, under the impression of duty, wantonly immolate at the shrine of superstition, those wretched victims whom the priests deliver over to them? Are they not savage tyrants, who have the rank injustice to violate thought; who have the folly to believe they can enslave it? Are they not delirious fanatics, on whom the law, dictated by the most inhuman prejudices, imposes the necessity of acting like ferocious brutes? Are not all those sovereigns, who to gratify the vanity of the priesthood, torment and persecute their subjects, who sacrifice to their anthropophagite gods human victims, men whom superstitious zeal has converted into tygers? Are not those priests, so careful of the soul's health, who insolently break into the sacred sanctuary of man's mind, to the end that they may find in his opinions motives for doing him an injury, abominable knaves, disturbers of the public repose, whom superstition honours, but whom virtue detests? What villains are more odious in the eyes of humanity, what depredators more hateful to the eye of reason, than those infamous inquisitors, who by the blindness of princes, by the delirium of monarchs, enjoy the advantage of passing judgment on their own enemies; who ruthlessly commit them to the charity of the flames? Nevertheless, the fatuity of the people makes even these monsters respected; the favour of kings covers them with kindness; the mantle of superstitious opinion shields them from the effect of the just execration of every honest man. Do not a thousand examples prove, that superstition has every where produced the most frightful ravages: that it has continually justified the most unaccountable horrors? Has it not a thousand times armed its votaries with the dagger of the homicide; let loose passions much wore terrible than those which it pretended to restrain; broken up the most sacred bonds by which mortals are connected with each other? Has it not, under the pretext of duty, under the colour of faith, under the semblance of zeal, under the sacred name of piety, favoured cupidity, lent wings to ambition, countenanced cruelty, given a spring to tyranny? Has it not legitimatized murder; given a system to perfidy; organized rebellion; made a virtue of regicide? Have not those princes who have been foremost as the avengers of heaven, who have been the lictors of superstition, frequently themselves become its victims? In short, has it not been the signal for the most dismal follies, the most wicked outrages, the most horrible massacres? Has not its altars been drenched with human gore? Under whatever form it has been exhibited, has it not always been the ostensible cause of the most bare-faced violation—of the sacred rights of humanity?
