To a friend, criticizing a philosophical work similar to those of Nicolas Malebranche and René Descartes, but lacking in style and even in correct French, wherein the author claims fire to be the main principle of everything, and the atmosphere to be nothing more than a mass of aqueous molecules which charge, moisten, and minimize the power of fire, without giving the proper scientific facts confirming his theory, concluding with the observation that the age of experimental philosophy has come to supersede that of visions: "Cet ouvrage n'est pas sans idées.
C'est une réverie de la tournure de celles de Malebranche et de Descartes, mais point de stile, quelquefoi même pas de Français. Si ce qu'il y a là dedans de systematique etait tombé dans la tête de Bufon, à force d'expressions, De Subtilités et de couleur, je ne sais ce qu'il n'en aurait pas fait. Dans l'état où cela est, point de sensation d'espérer. Selon l'auteur, Le feu est le principe de tout, excepté de son ouvrage. Quand on se propose de demonstrer qu'il n'y a point d'air, mais que notre athmosphère n'est qu'un amas de molecules aqueuses qui chargent, mouillent et [...] appesantissent Les ailes du feu, il faudrait commencer par l'aprovisionner d'un bon nombre de faits, et la reponse à tous ceux qu'on peut apposer, n'est ce rien? [...] Le reigne de la philosophie experimentale est venu, et celui des visions est passé [...]". - With pencil attribution at the lower edge. Number 24 stamped on verso.

To the printer of the Encyclopédie, André François Lebreton, written at a time when the first signs of censorship regarding Diderot and d'Alembert's great work were becoming evident. Diderot echoes rumours of legal proceedings that threaten the publication of the Encyclopédie, discussing a recent dinner at which Germain-Louis Chauvelin, the Marquis de Grosbois (1685-1762), Secretary of State for Foreign Affairs under Louis XV, mentioned that the Encyclopédie was to be treated in Parliament the coming Friday: "Je dinais aujourd'hui chez M.
Le Baron d'Holbach [i. e. Paul Henri Thiry, Baron d'Holbach, 1723-89]. Après diner, monsieur, il est venu une croix de St Louis de ses amis et des miens. Cette croix de St Louis venait de diner chez M. d'Argental où l'abbé Chauvelin s'était trouvé, et cet abbé Chauvelin avait dit que vendredi matin on agiterait au Parlement l'affaire de l'Encyclopédie, sur le rapport de M. Joly de Fleury. Avez-vous quelque connaissance de cela? J'en avais déjà entendu murmurer quelque chose. Je vous préviens afin que si vous avez des démarches à faire, vous ne les négligiez pas. J'aurai l'honneur de passer chez vous ce soir. On m'a dit que votre Rhumatisme allait mieux [...]". - At the end of the year 1758, after the publication of the seventh volume, d'Alembert decided to resign as co-director of the Encyclopédie and to stop contributing to it. From then on, the Encyclopédie, whose first volume had appeared in 1751, was in the hands of Diderot. A few months later, the publication of Helvétius's anti-religious work, "De l'Esprit", brought lightning down on the Encyclopédie. Parliament and the attorney general, Joseph-Omer Joly de Fleury, denounced Helvétius's book, the Encyclopédistes, and Diderot himself, who was suspected of heresy and of being involved with Helvétius's work. In January 1759, "De l'Esprit" was condemned by the French Parliament as well as by Pope Clement XIII to be torn and burned in public. Diderot, preparing to publish the eighth volume of the Encyclopédie, was accused by Joly de Fleury of plotting against religion and the state. On March 4th, the seven published volumes were banned, and further publication was forbidden..

To the French artist Saint-Aubin, suspecting he has forgotten their agreement that Saint-Aubin present him with a Venus and a plate of antique gems in exchange for receiving a copy of his first printed work. He suggests Saint-Aubin hand over the Venus, well wrapped, to the bearer of the present letter, unless he values his own work more highly than Diderot's and suspects he has struck a bad deal: "M. de Saint-Aubin a oublié qu'il y a entre lui et moi un traité. Je dois lui envoyer le premier ouvrage qu'on imprimera de moi.
Lui doit m'accorder en échange une Vénus Anadyomène et sa seconde petite planche des pierres antiques. Si cet oubli vient de ce qu'il estime plus son ouvrage que le mien et de ce qu'il croit avoir fait un mauvais marché, il a raison Si ce n'est pas cela, il remettra la Vénus au proteur, bien enveloppée de manière que sa main sale et grossière ne puisse la gâter [...]". - With a handwritten pencil note by Saint-Aubin: "1781 / I sent him a Venus before the letter in February 1782" (transl.)..

"Monsieur de St. Aubin has forgotten that there is a treaty between him and me. I am supposed to send him the first work that will be printed of mine. In return, he is to grant me a Venus Anadyomene and his second small plate of antique stones. If this forgetfulness stems from him valuing his work more than mine and thinking he made a bad deal, he is correct. If not, he will hand over the Venus to the bearer, well wrapped so that his dirty and coarse hand cannot spoil it. I send my regards and embrace him as always." At the end of the letter, Saint-Aubin added the date in pencil: "1781 I sent him a Venus before the letter in February 1782." The letter was transmitted by Eugène Charavay to Maurice Tourneux, who published and commented on it in "Diderot et Catherine II." (Paris, 1899, pp. 419-420). Very rare.
