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 misfortune? upon the earth.
