Assume the courage, then, I repeat it, to examine for yourself this religion, which, far from procuring you the happiness it promised, will only prove an inexhaustible source of inquietudes and alarms, and which will deprive you, sooner or later, of those rare qualities which render you so dear to society. Your interest exacts that you should render peace to your mind. It is your duty carefully to preserve that sweetness of temper, that indulgence, and that cheerfulness, by which you are so much endeared to all those who approach you. You owe happiness to yourself, and you owe it to those who surround you. Do not, then, abandon yourself to superstitious reveries, but collect all the strength of your judgment to combat the chimeras which torment your imagination. They will disappear as soon as you have considered them with your ordinary sagacity. Do not tell me, Madam, that your understanding is too weak to sound the depths of theology. Do not tell me, in the language of our priests, that the truths of religion are mysteries that we must adopt without comprehending them, and that it is necessary to adore in silence. By expressing themselves in this manner, do you not see they really proscribe and condemn the very religion to which they are so solicitous you should adhere? Whatever is supernatural is unsuited to man, and whatever is beyond his comprehension ought not to occupy his attention. To adore what we are not able to know, is to adore nothing. To believe in what we cannot conceive, is to believe in nothing. To admit without examination every thing we are directed to admit, is to be basely and stupidly credulous. To say that religion is above reason, is to recognize the fact that it was not made for reasonable beings; it is to avow that those who teach it have no more ability to fathom its depths than ourselves; it is to confess that our reverend doctors do not themselves understand the marvels with which they daily entertain us.
