Books are generally written for that part of a nation whose circumstances, education, and sentiments, place them above the commission of crimes. This enlightened portion of society, which governs the other, reads and judges of writings; if they contain maxims false or injurious, they are soon either condemned to oblivion, or held up to public execration; if they contain only truth, they are not in danger. Fanatics and ignorant people are the disturbers of society. Sensible, enlightened, and disinterested persons are ever the friends of peace.
You are not, Sir, of the number of pusillanimous thinkers, who believe that truth is capable of doing harm. It does harm to those only who deceive mankind, and to the rest of the human species it will always be useful. You ought long to have been convinced that the evils with which mankind are afflicted, arise only from our errors, our prejudices, our interests misunderstood, and the false ideas we attach to objects.
In fine, it is easy to see that the policy and morality of man have been particularly corrupted by their religious prejudices. Was it not religious and supernatural ideas which caused sovereigns to be looked upon as gods? It is then religion which raised up tyrants and despots; tyrants and despots made wicked laws; their example corrupted the great, the great corrupted the lower classes of mankind; these vitiated beings became unhappy slaves, employed either in injuring themselves, flattering the great, or struggling to get clear of their misery. Kings were styled images of God: they were absolute like him they created justice and injustice; their wills often sanctified oppression, violence, and rapine. The means of obtaining their favours were vice and meanness. Thus nations became filled with perverted citizens, who, under leaders corrupted by religious notions, made continually a war, either open or clandestine, and were left destitute of any motive for practising virtue.
Has this religion influenced the manners of sovereigns, who derive their divine power from it? Do we not behold princes, overflowing with faith, continually undertaking the most unjust wars; wasting the blood and treasure of their subjects; wrenching the bread from the hands of the poor; permitting and even commanding every species of injustice? Does this religion, considered by so many sovereigns as the support of their thrones, render them more humane, temperate, chaste, or faithful to their oaths? Alas! when we consult history, we there find sovereigns who were orthodox, zealous, and religious to a scruple, and at the same time guilty of perjury, usurpation, adultery, robbery, and murder; men who, in fine, behaved as if they feared not the God whom they honoured with their mouths. Among the courtiers who surrounded them, we see a continual alliance of Christianity and vice, devotion and iniquity, religion and treason. Among the priests of a poor and crucified God, who found their existence upon religion, and pretend that without it there could be no morality, do we not see reigning amongst them, pride, avarice, wantonness, and revenge?
Amongst us, education is very little attended to by the government, which shews the most profound indifference concerning an object the most essential to the happiness of states. With most modern nations public education is confined to teaching of languages, useless to most who learn them. Christians, instead of morality, inculcate the marvellous fables and incomprehensible dogmas of a religion extremely repugnant to right reason. At the first step a young man makes in his studies, he is taught that he ought to renounce the testimony of his senses, to reject his reason as an unfaithful guide, and blindly conform himself to the dictates of his masters? But who are these masters? Priests, whose interest it is to continue mankind in errors, of which they alone reap the advantage. Can the abject and isolated mind of these mercenary pedagogues be capable of instructing their pupils in that of which themselves are ignorant? Will they teach then to love the public good, to serve their country, to know the duties of the man and citizen? Certainly not; we can expect nothing from the hands of such teachers but ignorant and superstitious pupils, who, if they have profited of the lessons they have received, are unacquainted with every thing necessary in society, of which they must consequently become useless members.
On whatever side we cast our eyes, we see the study of the object most important to man totally neglected. Morality, in which I also comprehend policy, is considered of very little importance in European education. The only morality taught by Christians is, the enthusiastic, impracticable, contradictory, and uncertain morality contained in the gospel. This is calculated only to degrade the mind, to render virtue odious, to form abject slaves, and break the spring of the soul; or, if it is sown in warm and active minds, to produce turbulent fanatics, capable of shaking the foundations of society.
Notwithstanding the inutility and perversity of the morality which Christianity teaches mankind, its partisans presume to tell us, that without this religion we cannot have morals. But what is it to have morals, in; the language of Christians? It is to pray without ceasing, to frequent churches, to do penance, and to: abstain from pleasure; it is to live in selfishness and solitude. What good results to society from these practices, all of which may be observed by a man who has not the shadow of virtue? If such morals lead to heaven, they are very useless on earth. But certain it is, that a man may be a faithful observer of all that Christianity enjoins, without possessing any of the virtues which reason shews to be necessary to the support of political society.
It is necessary, then, to carefully distinguish Christian morality from political morality; the former makes saints, the latter citizens: one makes men useless, or even hurtful to the world; the other has for its object the formation of members useful to society; men active and vigorous, who are capable of serving it, who fulfil the duties of husbands, fathers, friends, and companions, whatever may be their metaphysical opinions, which, let theologists say what they will, are much less sure than the invariable rules of good sense.
In fact, it is certain, that man is a social being, who in all things seeks his own happiness; that he does good when he finds it his interest; that he is not commonly bad, because that would be contrary to his welfare. This being premised, let education teach men to know the relations which exist among themselves, and the duties arising from those relations; let governments, calling to their aid laws, rewards, and punishments, confirm the lessons given by education; let happiness accompany useful and virtuous actions, let shame, contempt, and chastisement be the rewards of vice. Then would mankind have a true morality, founded in their own nature upon their mutual wants, and the interest of nations at large. This morality, independent of the sublime notions of Theology, might perhaps have very little in common with Christian morality; but society has nothing to lose from this circumstance, as has already been proved.
When the people receive a proper education, which, by inspiring them early in life with virtuous principles, will habituate them to do homage to virtue, detest crimes, contemn vice, and shrink from infamy; such an education cannot be vain, when continual example shall prove to the citizens that talents and virtue are the only means of arriving at honour, fortune, distinction, consideration, and favour; and that vice conducts only to contempt and ignominy.
If the clergy have usurped from the sovereign power the right of instructing the people, let the latter re-assume its rights, or at least not suffer the former to enjoy the exclusive liberty of governing the manners of mankind, and dictating their morality. Let them teach, if they please, that their God transforms himself into bread, but let them never teach that we ought to hate or destroy those who refuse to believe this ineffable mystery. Let no individual in society have the power of exciting citizens to rebellion, of sowing discord, breaking the bands which unite the people amongst one another, and disturbing the public tranquillity for the sake of opinions. If it be said that all governments think it their interest to support religious prejudices, and manage the clergy through policy, although they themselves are undeceived; I answer, that it is easy to convince enlightened government, that it is their true interest to govern a happy people; that upon the happiness it procures the nation, depends the stability
