Atheism, then, as well as philosophy, like all profound abstruse sciences, is not calculated for the vulgar; neither is it suitable to the great mass of mankind. There are, in all populous, civilized nations, persons whose circumstances enable them to devote their time to meditation, whose easy finances afford them leisure to make deep researches into the nature of things, who frequently make useful discoveries, which, sooner or later, after they have been submitted to the infallible test of experience, when they have passed the fiery ordeal of truth, extend widely their salutary effects, become extremely beneficial to society, highly advantageous to individuals. The geometrician, the chemist, the mechanic, the natural philosopher, the civilian, the artizan himself, are industriously employed, either in their closets, or in their workshops, seeking the means to serve society, each in his sphere: nevertheless, not one of their sciences or professions are familiar to the illiterate; not one of the arts with which they are respectively occupied, are known to the uninitiated: these, however, do not fail, in the long run, to profit by them, to reap substantive advantages from those labours, of which they themselves have no idea. It is for the mariner, that the astronomer explores his arduous science; it is for him the geometrician calculates; for his use the mechanic plies his craft: it is for the mason, for the carpenter, for the labourer, that the skilful architect studies his orders, lays down well-proportioned elaborate plans. Whatever may be the pretended utility of Pneumatology, whatever may be the vaunted advantages of superstitious opinions, the wrangling polemic, the subtle theologian, cannot boast either of toiling, of writing, or of disputing for the advantage of the people, whom, notwithstanding, he contrives to tax, very exorbitantly, for those systems they can never understand; from whom he levies the most oppressive contributions, as a remuneration for the detail of those mysteries, which under any possible circumstances, cannot, at any time whatever, be of the slightest benefit to them. It is not, then, for the multitude that a philosopher should propose to himself, either to write or to meditate: the Code of Nature, or the principles of atheism, as the priest calls it, are not, as we have shewn, even calculated for the meridian of a great number of persons, who are frequently too much prepossessed in favour of the received prejudices, although extremely enlightened on other points. It is extremely rare to find men, who, to an enlarged mind, extensive knowledge, great talents, join either a well regulated imagination, or the courage necessary to successfully oppugn habitual errors; triumphantly to attack those chimerical systems, with which the brain has been inoculated from the first hour of its birth. A secret bias, an invincible inclination, frequently, in despite of all reasoning, re-conducts the most comprehensive, the best fortified, the most liberal minds, to those prejudices which have a wide-spreading establishment; of which they have themselves taken copious draughts during the early stages of life. Nevertheless, those principles, which at first appear strange, which by their boldness seem revolting, from which timidity flies with trepidation, when they have the sanction of truth, gradually insinuate themselves into the human mind, become familiar to its exercise, extend their happy influence on every side, and finally produce the most substantive advantages to society. In time, men habituate themselves to ideas which originally they looked upon as absurd; which on a superficial glance they contemplated as either noxious or irrational: at least, they cease to consider those as odious, who profess opinions upon subjects on which experience makes it evident they may be permitted to have doubts, without imminent danger to public tranquillity.

Then the diffusion of ideas among mankind is not an event to be dreaded: if they are truths, they will of necessity be useful: by degrees they will fructify. The man who writes, must neither fix his eyes upon the time in which he lives, upon his actual fellow citizens, nor upon the country he inhabits. He must speak to the human race; he must instruct future generations; he must extend his views into the bosom of futurity; in vain he will expect the eulogies of his contemporaries; in vain will he flatter himself with seeing his reasoning adopted; in vain he will soothe himself with the pleasing reflection, that his precocious principles will be received with kindness; if he has exhibited truisms, the ages that shall follow will do justice to his efforts; unborn nations shall applaud his exertions; his future countrymen shall crown his sturdy attempts with those laurels, which interested prejudice withholds from him in his own days; it must therefore be from posterity, he is to expect the need of applause due to his services; the present race is hermetically sealed against him: meantime let him content himself with having done well; with the secret suffrages of those few friends to veracity who are so thinly spread over the surface of the earth. It is after his death, that the trusty reasoner, the faithful writer, the promulgator of sterling principles, the child of simplicity, triumphs; it is then that the stings of hatred, the shafts of envy, the arrows of malice, either exhausted or blunted, enable mankind to judge with impartiality; to yield to conviction; to establish eternal truth upon its own imperishable altars, which from its essence must survive all the error of the earth. It is then that calumny, crushed like the devouring snail by the careful gardener, ceases to besmear the character of an honest man, while its venomous slime, glazed by the sun, enables the observant spectator to trace the filthy progress it had made.

It is a problem with many people, if truth may not be injurious? The best intentioned persons are frequently in great doubt upon this important point. The fact is, it never injures any but those who deceive mankind: this has, however, the greatest interest in being undeceived. Truth may be injurious to the individual who announces it, but it can never by any possibility harm the human species; never can it be too distinctly presented to beings, always either little disposed to listen to its dictates, or too slothful to comprehend its efficacy. If all those who write to publish important truths, which, of all others, are ever considered the most dangerous, were sufficiently ardent for the public welfare to speak freely, even at the risk of displeasing their readers, the human race would be much more enlightened, much happier than it now is. To write in ambiguous terms, is very frequently to write to nobody. The human mind is idle; we must spare it, as much as possible, the trouble of reflection; we must relieve it from the embarrassment of intense thinking. What time does it not consume, what study does it not require, at the present day, to unravel the amphibological oracles of the ancient philosophers, whose actual sentiments are almost entirely lost to the present race of men? If truth be useful to human beings, it is an injustice to deprive them of its advantages; if truth ought to be admitted, we must admit its consequences, which are also truths. Man, taken generally, is fond of truth, but its consequences often inspire him with so much dread, so alarm his imbecility, that, frequently, he prefers remaining in error, of which a confirmed habit prevents him from feeling the deplorable effects. Besides, we shall say with Hobbes, "that we cannot do men any harm by proposing truth to them; the worst mode is to leave them in doubt, to let them remain in dispute." If an author who writes be deceived, it is because he may have reasoned badly. Has he laid down false principles? It remains to examine them. Is his system fallacious? Is it ridiculous? It will serve to make truth appear with the greatest splendor: his work will fall into contempt; the writer, if he be witness to its fall, will be sufficiently punished for his temerity; if he be defunct, the living cannot disturb his ashes. No man writes with a design to injure his fellow creatures; he always proposes to himself to merit their suffrages, either by amusing them, by exciting their curiosity, or by communicating to them discoveries, which he believes useful. Above all, no work can be really dangerous, if it contains truth. It would not be so, even if it contained principles evidently contrary to experience—opposed to good sense. Indeed, what would result from a work that should now tell us the sun is not luminous; that parricide is legitimate; that robbery is allowable; that adultery is not a crime? The smallest reflection would make us feet the falsity of these principles; the whole human race would protest against them. Men would laugh at the folly of the author; presently his book, together with his name, would be known only by its ridiculous extravagancies. There is nothing but superstitious follies that are pernicious to mortals; and wherefore? It is because authority always pretends to establish them by violence; to make them pass for substantive virtues; rigorously punishes those who shall be disposed to smile at their inconsistency, or examine into their pretensions. If man was more rational, he would examine superstitious opinions as he examines every thing else; he would look upon theological theories with the same eyes that he contemplates systems of natural philosophy, or problems in geometry: the latter never disturbs the repose of society, although they sometimes excite very warm disputes in the learned world. Theological quarrels would never be attended with any evil consequences, if man could gain the desirable point of making those who exercise power, feel that the disputes of persons, who do not themselves understand the marvellous questions upon which they never cease wrangling, ought not to give birth to any other sensations than those of indifference; to rouse no other passion than that of contempt.

It is, at least, this indifference not speculative theories, so just, so rational, so advantageous for states, that sound philosophy may propose to introduce, gradually, upon the earth. Would not the human race be much happier—if the sovereigns of the world, occupied with the welfare of their subjects, leaving to superstitious theologians their futile contests, making their various systems yield to healthy politics; obliged these haughty ministers to become citizens; carefully prevented their disputes from interrupting the public tranquillity? What advantage might there not result to science; what a start would be given to the progress of the human mind, to the cause of sound morality, to the advancement of equitable jurisprudence, to the improvement of legislation, to the diffusion of education, from an unlimited freedom of thought? At present, genius every where finds trammels; superstition invariably opposes itself to its course; man, straitened with bandages, scarcely enjoys the free use of any one of his faculties; his mind itself is cramped; it appears continually wrapped up in the swaddling clothes of infancy. The civil power, leagued with spiritual domination, appears only disposed to rule over brutalized slaves, shut up in a dark prison, where they reciprocally goad each other with the efferverscence of their mutual ill humour. Sovereigns, in general, detest liberty of thought, because they fear truth; this appears formidable to them, because it would condemn their excesses; these irregularities are dear to them, because they do not, better than their subjects, understand their true interests; properly considered, these ought to blend themselves into one uniform mass.

Let not the courage of the philosopher, however, be abated by so many united obstacles, which would appear for ever to exclude truth from its proper dominion; to banish reason from the mind of man; to spoil nature of her imprescriptible rights. The thousandth part of those cares which are bestowed to infect the human mind, would be amply sufficient to make it whole. Let us not, then, despair of the case: do not let us do man the injury to believe that truth is not made for him; his mind seeks after it incessantly; his heart desires it faithfully; his happiness demands it with an imperious voice; he only either fears it, or mistakes it, because superstition, which has thrown all his ideas into confusion, perpetually keeps the bandeau of delusion fast bound over his eyes; strives, with an almost irresistible force, to render him an entire stranger to virtue.

Maugre the prodigious exertions that are made to drive truth from the earth; in spite of the extraordinary pains used to exile reason—of the uninterrupted efforts to expel true science from the residence of mortals; time, assisted by the progressive knowledge of ages, may one day be able to enlighten even those princes who are the most outrageous in their opposition to the illumination of the human mind; who appear such decided enemies to justice, so very determined against the liberties of mankind. Destiny will, perhaps, when least expected, conduct these wandering outcasts to the throne of some enlightened, equitable, courageous, generous, benevolent sovereign, who, smitten with the charms of virtue, shall throw aside duplicity, frankly acknowledge the true source of human misery, and apply to it those remedies with which wisdom has furnished him: perhaps he may feel, that those systems, from whence it is pretended he derives his power, are the true scourges of his people; the actual cause of his own weakness: that the official expounders of these systems are his most substantial enemies—his most formidable rivals; he may find that superstition, which he has been taught to look upon as the main support to his authority, in point of fact only enfeebles it—renders it tottering: that superstitious morality, false in its principles, is only calculated to pervert his subjects; to break down their intrepidity; to render them perfidious; in short, to give them the vices of slaves, in lieu of the virtues of citizens. A prince thus disentangled from prejudice, will perhaps behold, in superstitious errors, the fruitful source of human sorrows, and commiserations, the condition of his race, it may be, will generously declare, that they are incompatible with every equitable administration.

Until this epoch, so desirable for humanity, shall arrive, the principles of naturalism will be adopted only by a small number of liberal-minded men, who shall dive below the surface; these cannot flatter themselves either with making proselytes, or having a great number of approvers: on the contrary, they will meet with zealous adversaries, with ardent contemners, even in those persons who upon every other subject discover the most acute minds; display the most consummate knowledge. Those men who possess the greatest share of ability, as we have already observed, cannot always resolve to divorce themselves completely from their superstitious ideas; imagination, so necessary to splendid talents, frequently forms in them an insurmountable obstacle to the total extinction of prejudice; this depends much more upon the judgment than upon the mind. To this disposition, already so prompt to form illusions to them, is also to be joined the force of habit; to a great number of men, it would he wresting from them a portion of themselves to take away their superstitious notions; it would be depriving them of an accustomed aliment; plunging them into a dreadful vacuum: obliging their distempered minds to perish for want of exercise. Menage remarks, "that history speaks of very few incredulous women, or female atheists:" this is not surprising; their organization renders them fearful; their nervous system undergoes periodical variations; the education they receive disposes them to credulity. Those among them who have a sound constitution, who have a well ordered imagination, have occasion for chimeras suitable to occupy their leisure; above all, when the world abandons them, then superstitious devotion, with its attractive ceremonies, becomes either a business or an amusement.

Let us not be surprised, if very intelligent, extremely learned men, either obstinately shut their eyes, or run counter to their ordinary sagacity, every time there is a question respecting an object which they have not the courage to examine with that attention they lend to many others. Lord Chancellor Bacon pretends, "that a little philosophy disposes men to atheism, but that great depth re-conducts them to religion." If we analyze this proposition, we shall find it signifies, that even moderate, indifferent thinkers, are quickly enabled to perceive the gross absurdities of superstition; but that very little accustomed to meditate, or else destitute of those fixed principles which could serve them for a guide, their imagination presently replaces them in the theological labyrinth, from whence reason, too weak for the purpose, appeared disposed to withdraw them: these timid souls, who fear to take courage, with minds disciplined to be satisfied with theological solutions, no longer see in nature any thing but an inexplicable enigma; an abyss which it is impossible for them to fathom: these, habituated to fix their eyes upon an ideal, mathematical point, which they have made the centre of every thing, whenever they lose sight of it, find the universe becomes an unintelligible jumble to them; then the confusion in which they feel themselves involved, makes them rather prefer returning to the prejudices of their infancy, which appear to explain every thing, than to float in the vacuum, or quit a foundation which they judge to be immoveable. Thus the proposition of Bacon should seem, to indicate nothing, except it be that the most experienced persons cannot at all times defend themselves against the illusions of their imagination; the impetuosity of which resists the strongest reasoning.

Nevertheless, a deliberate study of nature is sufficient to undeceive every man who will calmly consider things: he will discover that the phenomena of the world is connected by links, invisible to superficial notice, equally concealed from the too impetuous observer, but extremely intelligible to him who views her with serenity. He will find that the most unusual, the most marvellous, as well as the most trifling, or ordinary effects, are equally inexplicable, but that they all equally flow from natural causes; that supernatural causes, under whatever name they way be designated, with whatever qualities they may be decorated, will never do more than increase difficulties; will only make chimeras multiply. The simplest observation will incontestibly prove to him that every thing is necessary; that all the effects he perceives are material; that they can only originate in causes of the same nature, when he even shall not be able to recur to them by the assistance of his senses. Thus his mind, properly directed, every where show him nothing but matter, sometimes acting in a manner which his organs permit him to follow, at others in a mode imperceptible by the faculties he possesses: he will see that all beings follow constant invariable laws, by which all combinations are united and destroyed; he will find that all forms change, but that, nevertheless, the great whole ever remains the same. Thus, cured of the idle notions with which he was imbued, undeceived in those erroneous ideas, which from habit be attached to imaginary systems, he will cheerfully consent to be ignorant of whatever his organs do not enable him to compass; he will know that obscure terms, devoid of sense, are not calculated to explain difficulties; guided by reason, he will throw aside all hypothesis of the imagination; the champion of rectitude, he will attach himself to realities, which are confirmed by experience, which are evidenced by truth.

The greater number of those who study nature, frequently do not consider, that prejudiced eyes will never discover more than that which they have previously determined to find: as soon as they perceive facts contrary to their own ideas, they quickly turn aside, and believe their visual organs have deceived them; if they return to the task, it is in hopes to find means by which they may reconcile the facts to the notions with which their own mind is previously tinctured. Thus we find enthusiastic philosophers, whose determined prepossession shews them what they denominate incontestible evidences of the systems with which they are pre-occupied, even in those things, that most openly contradict their hypothesis: hence those pretended demonstrations of the existence of theories, which are drawn from final causes—from the order of nature—from the kindness evinced to man, &c. Do these same enthusiasts perceive disorder, witness calamities? They induct new proofs of the wisdom, fresh evidence of the intelligence, additional testimony to the bounty of their system, whilst all these occurrences as visibly contradict these qualities, as the first seem to confirm or to establish them. These prejudiced observers are in an ecstacy at the sight of the periodical motions of the planets; at the order of the stars; at the various productions of the earth; at the astonishing harmony in the component parts of animals: in that moment, however, they forget the laws of motion; the powers of gravitation; the force of attraction and repulsion; they assign all these striking phenomena to unknown causes, of which they have no one substantive idea. In short, in the fervor of their imagination they place man in the centre of nature; they believe him to be the object, the end, of all that exists; that it is for his convenience every thing is made; that it is to rejoice his mind, to pleasure his senses, that the whole was created; whilst they do not perceive, that very frequently the entire of nature appears to be loosed against his weakness; that the elements themselves overwhelm him with calamity; that destiny obstinately persists in rendering him the most miserable of beings. The progress of sound philosophy will always be fatal to superstition, whose notions will be continually contradicted by nature.
