When we wish to examine in a cool, calm way the opinions of men, we are very much surprised to find that in those which we consider the most essential, nothing is more rare than to find them using common sense; that is to say, the portion of judgment sufficient to know the most simple truths, to reject the most striking absurdities, and to be shocked by palpable contradictions. We have an example of this in Theology, a science revered in all times, in all countries, by the greatest number of mortals; an object considered the most important, the most useful, and the most indispensable to the happiness of society. If they would but take the trouble to sound the principles upon which this pretended science rests itself, they would be compelled to admit that the principles which were considered incontestable, are but hazardous suppositions, conceived in ignorance, propagated by enthusiasm or bad intention, adopted by timid credulity, preserved by habit, which never reasons, and revered solely because it is not comprehended. Some, says Montaigne, make the world believe that which they do not themselves believe; a greater number of others make themselves believe, not comprehending what it is to believe. In a word, whoever will consult common sense upon religious opinions, and will carry into this examination the attention given to objects of ordinary interest, will easily perceive that these opinions have no solid foundation; that all religion is but a castle in the air; that Theology is but ignorance of natural causes reduced to a system; that it is but a long tissue of chimeras and contradictions; that it presents to all the different nations of the earth only romances devoid of probability, of which the hero himself is made up of qualities impossible to reconcile, his name having the power to excite in all hearts respect and fear, is found to be but a vague word, which men continually utter, being able to attach to it only such ideas or qualities as are belied by the facts, or which evidently contradict each other.
The notion of this imaginary being, or rather the word by which we designate him, would be of no consequence did it not cause ravages without number upon the earth. Born into the opinion that this phantom is for them a very interesting reality, men, instead of wisely concluding from its incomprehensibility that they are exempt from thinking of it, on the contrary, conclude that they can not occupy themselves enough about it, that they must meditate upon it without ceasing, reason without end, and never lose sight of it. The invincible ignorance in which they are kept in this respect, far from discouraging them, does but excite their curiosity; instead of putting them on guard against their imagination, this ignorance makes them positive, dogmatic, imperious, and causes them to quarrel with all those who oppose doubts to the reveries which their brains have brought forth. What perplexity, when we attempt to solve an unsolvable problem! Anxious meditations upon an object impossible to grasp, and which, however, is supposed to be very important to him, can but put a man into bad humor, and produce in his brain dangerous transports. When interest, vanity, and ambition are joined to such a morose disposition, society necessarily becomes troubled. This is why so many nations have often become the theaters of extravagances caused by nonsensical visionists, who, publishing their shallow speculations for the eternal truth, have kindled the enthusiasm of princes and of people, and have prepared them for opinions which they represented as essential to the glory of divinity and to the happiness of empires. We have seen, a thousand times, in all parts of our globe, infuriated fanatics slaughtering each other, lighting the funeral piles, committing without scruple, as a matter of duty, the greatest crimes. Why? To maintain or to propagate the impertinent conjectures of enthusiasts, or to sanction the knaveries of impostors on account of a being who exists only in their imagination, and who is known only by the ravages, the disputes, and the follies which he has caused upon the earth.
Originally, savage nations, ferocious, perpetually at war, adored, under various names, some God conformed to their ideas; that is to say, cruel, carnivorous, selfish, greedy of blood. We find in all the religions of the earth a God of armies, a jealous God, an avenging God, an exterminating God, a God who enjoys carnage and whose worshipers make it a duty to serve him to his taste. Lambs, bulls, children, men, heretics, infidels, kings, whole nations, are sacrificed to him. The zealous servants of this barbarous God go so far as to believe that they are obliged to offer themselves as a sacrifice to him. Everywhere we see zealots who, after having sadly meditated upon their terrible God, imagine that, in order to please him, they must do themselves all the harm possible, and inflict upon themselves, in his honor, all imaginable torments. In a word, everywhere the baneful ideas of Divinity, far from consoling men for misfortunes incident to their existence, have filled the heart with trouble, and given birth to follies destructive to them. How could the human mind, filled with frightful phantoms and guided by men interested in perpetuating its ignorance and its fear, make progress? Man was compelled to vegetate in his primitive stupidity; he was preserved only by invisible powers, upon whom his fate was supposed to depend. Solely occupied with his alarms and his unintelligible reveries, he was always at the mercy of his priests, who reserved for themselves the right of thinking for him and of regulating his conduct.
Thus man was, and always remained, a child without experience, a slave without courage, a loggerhead who feared to reason, and who could never escape from the labyrinth into which his ancestors had misled him; he felt compelled to groan under the yoke of his Gods, of whom he knew nothing except the fabulous accounts of their ministers. These, after having fettered him by the ties of opinion, have remained his masters or delivered him up defenseless to the absolute power of tyrants, no less terrible than the Gods, of whom they were the representatives upon the earth. Oppressed by the double yoke of spiritual and temporal power, it was impossible for the people to instruct themselves and to work for their own welfare. Thus, religion, politics, and morals became sanctuaries, into which the profane were not permitted to enter. Men had no other morality than that which their legislators and their priests claimed as descended from unknown empyrean regions. The human mind, perplexed by these theological opinions, misunderstood itself, doubted its own powers, mistrusted experience, feared truth, disdained its reason, and left it to blindly follow authority. Man was a pure machine in the hands of his tyrants and his priests, who alone had the right to regulate his movements. Always treated as a slave, he had at all times and in all places the vices and dispositions of a slave.
These are the true sources of the corruption of habits, to which religion never opposes anything but ideal and ineffectual obstacles; ignorance and servitude have a tendency to make men wicked and unhappy. Science, reason, liberty, alone can reform them and render them more happy; but everything conspires to blind them and to confirm them in their blindness. The priests deceive them, tyrants corrupt them in order to subjugate them more easily. Tyranny has been, and will always be, the chief source of the depraved morals and habitual calamities of the people. These, almost always fascinated by their religious notions or by metaphysical fictions, instead of looking upon the natural and visible causes of their miseries, attribute their vices to the imperfections of their nature, and their misfortunes to the anger of their Gods; they offer to Heaven vows, sacrifices, and presents, in order to put an end to their misfortunes, which are really due only to the negligence, the ignorance, and to the perversity of their guides, to the folly of their institutions, to their foolish customs, to their false opinions, to their unreasonable laws, and especially to their want of enlightenment. Let the mind be filled early with true ideas; let man's reason be cultivated; let justice govern him; and there will be no need of opposing to his passions the powerless barrier of the fear of Gods. Men will be good when they are well taught, well governed, chastised or censured for the evil, and justly rewarded for the good which they have done to their fellow-citizens. It is idle to pretend to cure mortals of their vices if we do not begin by curing them of their prejudices. It is only by showing them the truth that they can know their best interests and the real motives which will lead them to happiness. Long enough have the instructors of the people fixed their eyes on heaven; let them at last bring them back to the earth. Tired of an incomprehensible theology, of ridiculous fables, of impenetrable mysteries, of puerile ceremonies, let the human mind occupy itself with natural things, intelligible objects, sensible truths, and useful knowledge.
Let the vain chimeras which beset the people be dissipated, and very soon rational opinions will fill the minds of those who were believed fated to be always in error. To annihilate religious prejudices, it would be sufficient to show that what is inconceivable to man can not be of any use to him. Does it need, then, anything but simple common sense to perceive that a being most clearly irreconcilable with the notions of mankind, that a cause continually opposed to the effects attributed to him; that a being of whom not a word can be said without falling into contradictions; that a being who, far from explaining the mysteries of the universe, only renders them more inexplicable; that a being to whom for so many centuries men addressed themselves so vainly to obtain their happiness and deliverance from their sufferings; does it need, I say, more than simple common sense to understand that the idea of such a being is an idea without model, and that he is himself evidently not a reasonable being? Does it require more than common sense to feel that there is at least delirium and frenzy in hating and tormenting each other for unintelligible opinions of a being of this kind? Finally, does it not all prove that morality and virtue are totally incompatible with the idea of a God, whose ministers and interpreters have painted him in all countries as the most fantastic, the most unjust, and the most cruel of tyrants, whose pretended wishes are to serve as rules and laws for the inhabitants of the earth? To discover the true principles of morality, men have no need of theology, of revelation, or of Gods; they need but common sense; they have only to look within themselves, to reflect upon their own nature, to consult their obvious interests, to consider the object of society and of each of the members who compose it, and they will easily understand that virtue is an advantage, and that vice is an injury to beings of their species.
Let us teach men to be just, benevolent, moderate, and sociable, not because their Gods exact it, but to please men; let us tell them to abstain from vice and from crime, not because they will be punished in another world, but because they will suffer in the present world. There are, says Montesquieu, means to prevent crime, they are sufferings; to change the manners, these are good examples. Truth is simple, error is complicated, uncertain in its gait, full of by-ways; the voice of nature is intelligible, that of falsehood is ambiguous, enigmatical, and mysterious; the road of truth is straight, that of imposture is oblique and dark; this truth, always necessary to man, is felt by all just minds; the lessons of reason are followed by all honest souls; men are unhappy only because they are ignorant; they are ignorant only because everything conspires to prevent them from being enlightened, and they are wicked only because their reason is not sufficiently developed.
