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.
