With regard to the interpreters and commentators, who for so many ages have painfully toiled to elucidate the divine laws, to explain the sacred books, and to fix the dogmas of Christianity, their very labors ought to inspire us with suspicion concerning a religion which is founded upon such books and which preaches such dogmas. They prove that works emanating from the Supreme Being are obscure, unintelligible, and need human assistance in order to be understood by those to whom the Divinity wished to reveal his will. The laws of a wise God would be simple and clear. Defective laws alone need interpreters.
It is not, then, Madam, upon these interpreters that you should rely; it is upon yourself; it is your own reason that you should consult. It is your happiness, it is your repose, that is in question; and these objects are too serious to allow their decision to be delegated to any others than yourself. If religion is as important as we are assured, it undoubtedly merits the greatest attention. If it is upon this religion that depends the happiness of men both in this world and in another, there is no subject which interests us so strongly, and which consequently demands a more thorough, careful, and considerate examination. Can there be any thing, then, more strange than the conduct of the great majority of men? Entirely convinced of the necessity and importance of religion, they still never give themselves the trouble to examine it thoroughly; they follow it in a spirit of routine and from habit; they never give any reason for its dogmas; they revere it, they submit to it, and they groan under its weight, without ever inquiring wherefore. In fine, they rely upon others to examine it; and they whose judgment they so blindly receive are precisely those persons upon whose opinions they should look with the most suspicion. The priests arrogate the possession of judging exclusively and without appeal of a system evidently invented for their own utility. And what is the language of these priests? Visibly interested in maintaining the received opinions, they exhibit them as necessary to the public good, as useful and consoling for us all, as intimately connected with morality, as indispensable to society, and, in a word, as of the very greatest importance. After having thus prepossessed our minds, they next prohibit our examining the things so important to be known. What must be thought of such conduct? You can only conclude that they desire to deceive you, that they fear examination only because religion cannot sustain it, and that they dread reason because it is able to unveil the incalculably dangerous projects of the priesthood against the human race.
For these reasons, Madam, as I cannot too often repeat, examine for yourself; make use of your own understanding; seek the truth in the sincerity of your heart; reduce prejudice to silence; throw off the base servitude of custom; be suspicious of imagination; and with these precautions, in good faith with yourself, you can weigh with an impartial hand the various opinions concerning religion. From whatever source an opinion may come, acquiesce only in that which shall be convincing to your understanding, satisfactory to your heart, conformable to a healthy morality, and approved by virtue. Reject with disdain whatever shocks your reason, and repulse with horror those notions so criminal and injurious to morality which religion endeavors to palm off for supernatural and divine virtues.
What do I say? Amiable and wise Eugenia, examine rigorously the ideas that, by your own desire, I shall hereafter present you. Let not your confidence in me, or your deference to my weak understanding, blind you in regard to my opinions. I submit them to your judgment. Discuss them, combat them, and never give them your assent until you are convinced that in them you recognize the truth. My sentiments are neither divine oracles nor theological opinions which it is not permitted to canvass. If what I say is true, adopt my ideas. If I am deceived, point out my errors, and I am ready to recognize them and to subscribe my own condemnation. It will be very pleasant, Madam, to learn truths of you which, up to the present time, I have vainly sought in the writings of our divines. If I have at this moment any advantage over you, it is due entirely to that tranquillity which I enjoy, and of which at present you are unhappily deprived. The agitations of your mind, the inquietudes of your body, and the attacks of an exacting and ceremonious devotion, with which your soul is perplexed, prevent you, for the moment, from seeing things coolly, and hinder you from making use of your own understanding; but I have no doubt that soon your intellect, strengthened by reason against vain chimeras, will regain its natural vigor and the superiority which belongs to it. In awaiting this moment that I foresee and so much desire, I shall esteem myself extremely happy if my reflections shall contribute to render you that tranquillity of spirit so necessary to judge wisely of things, and without which there can be no true happiness.
I perceive, Madam, though rather tardily, the length of this letter; but I hope you will pardon it, as well as my frankness. They will at least prove the lively interest I take in your painful situation, the sincere desire I feel to bring it to a termination, and the strong inclination which actuates me to restore you to your accustomed serenity. Less pressing motives would never have been sufficient to make me break silence. Your own positive orders were necessary to lead me to speak of objects which, once thoroughly examined, give no uneasiness to a healthy mind. It has been a law with me never to explain myself upon the subject of religion. Experience has often convinced me that the most useless of enterprises is to seek to undeceive a prejudiced mind. I was very far from believing that I ought ever to write upon these subjects. You alone, Madam, had the power to conquer my indolence, and to impel me to change my resolution. Eugenia afflicted, tormented with scruples, and ready to plunge herself into gloomy austerities and superstitions, calculated to render her unamiable to others, without contributing happiness to herself, honored me with her confidence, and requested counsel of her friend. She exacted that I should speak. "It is enough," I said; "let me write for Eugenia; let me endeavor to restore the repose she has lost; let me labor with ardor for her upon whose happiness that of so many others is dependent."
Such, Madam, are the motives which induce me to take my pen in hand. In looking forward to the time when you will be undeceived, I shall dare at least to flatter myself that you will not regard me with the same eyes with which priests and devotees look upon every one who has the temerity to contradict their ideas. To believe them, every man who declares himself against religion is a bad citizen, a madman armed to justify his passions, a perturbator of the public repose, and an enemy of his fellow-citizens, that cannot be punished with too much rigor. My conduct is known to you; and the confidence with which you honor me is sufficient for my apology. It is for you alone that I write. It is to dissipate the clouds that obscure your mental horizon that I communicate reflections which, but for reasons so pressing, I should have always enclosed in my own bosom. If by chance they shall hereafter fall into other hands than yours, and be found of some utility, I shall felicitate myself for having contributed to the establishment of happiness by leading back to reason minds which had wandered from it, by making truth to be felt and known, and by unmasking impostures which have caused so many misfortunes upon the earth.
In a word, I submit my reasoning to your judgment, I confide fully in your discretion, and I allow myself to conclude that my ideas, after you are disabused of the vain terrors with which you are now oppressed, will fully convince you that this religion, which is exhibited to men as a concern the most important, the most true, the most interesting, and the most useful, is only a tissue of absurdities, is calculated to confound reason, to disturb the understanding, and can be advantageous to none save those who make use of it to govern the human race. I shall acknowledge myself in the wrong if I do not prove, in the clearest manner, that religion is false, useless, and dangerous, and that morality, in its stead, should occupy the spirits and animate the souls of all men.
I shall enter more particularly into the subject in my next letter. I shall go back to first principles, and in the course of this correspondence I flatter myself I shall completely demonstrate that these objects, which theology endeavors to render intricate, and to envelop with clouds, in order to make them more respectable and sacred, are not only entirely susceptible of being understood by you, but that they are likewise within the comprehension of every one who possesses even an ordinary share of good sense. If my frankness shall appear too undisguised, I beg you to consider, Madam, that it is necessary I should address you explicitly and clearly. I now consider it my duty to administer an energetic and prompt remedy for the malady with which I perceive you to be attacked. Besides, I venture to hope that in a short time you will feel gratified that I have shown you the truth in all its integrity
