However this may be, we have spared no pains to reestablish the text in all its purity; and we venture to say, that, with the exception of four or five passages, which we found corrupted in all the manuscripts that we had an opportunity to collate, and which we have amended to the best of our ability, the edition of these letters that we now offer to the reader will probably conform almost exactly with the original manuscript of the author. With regard to the author's name and quality we can offer nothing but conjectures. The only particulars of his life upon which there is a general agreement are, that he lived upon terms of great intimacy with the Marquis de la Fare, the Abbe de Chaulieu, the Abbe Terrasson, Fontenelle, M. de Lassere, &c. The late MM. Du Marsais and Falconnet have often been heard to declare that these letters were composed by some one belonging to the school of Seaux. All that we can pronounce with certainty is the fact, that it is only necessary to read the work to be entirely convinced the author was a man of extensive knowledge, and one who had meditated profoundly concerning the matters upon which he has treated. His style is clear, simple, easy, and in which we may remark a certain urbanity, that leads us to be sure that he was not an obscure individual, nor one to whom good company and polished society were unfamiliar. But what especially distinguishes this work, and which should endear it to all good and virtuous people, is the signal honesty which pervades and characterizes it from the very beginning to the end. It is impossible to read it without conceiving the highest idea of the author's probity, whoever he may have been--without desiring to have had him for a friend, to have lived with him, and, in a word, without rendering justice to the rectitude of his intentions, even when we do not approve of his sentiments. The love of virtue, universal benevolence, respect to the laws, an inviolable attachment to the duties of morality, and, in fine, all that can contribute to render men better, is strongly recommended in these Letters. If, on the one hand he completely overthrows the ruinous edifice of Christianity, it is to erect, on the other hand, the immovable foundations of a system of morality legitimately established upon the nature of man, upon his physical wants, and upon his social relations--a base infinitely better and more solid than that of religion, because sooner or later the lie is discovered, rejected, and necessarily drags with it what served to sustain it. On the contrary, the truth subsists eternally, and consolidates itself as it grows old: _Opinionum commenta delet dies, naturae judicia confirmat._*
