Dissertation sur la nature et la propagation du feu (1738)

In 1737, the Académie Royale des Sciences announced a competition devoted to the question of the nature and the propagation of fire. It was Voltaire who had the idea to compete. To begin with, he and Du Châtelet collaborated on this issue, but then Du Châtelet broke with his ideas and worked out her own draft (she could work only by night, so that Voltaire did not suspect anything of her project). Neither Voltaire nor Du Châtelet were among the winners, because both adhered to Newton’s physics, which was not recognised by the Académie. However, after some intervention by Voltaire, focused on various members of the Académie, they published the works of these two natural philosophers in 1738. Du Châtelet’s edition from 1744 shows some major changes: Du Châtelet refers more strongly to Leibniz and less to Descartes, while remaining supportive of most of Newton’s ideas.

« Lettre sur les Eléments de la Philosophie de Newton » (1738)

Du Châtelet published a paper in the Journal des sçavans, which the Journal editors described as an “extrait” of Voltaire’s book. This is potentially misleading since it is more akin to a book review: it summarizes the contents but also offers plenty of opinions and evaluations, and contextualises the Elements in the debates of the time. The book review was published twice: first in Paris in September 1738, and then in Amsterdam in December 1738.

Institutions de physique (1740)

The Institutions de physique is introduced in the Preface as an introductory text for her son’s education but in fact aims to develop a metaphysically founded physics in the broader sense of knowledge of nature. Initially published anonymously, it was arguably the first general introductory text on theoretical physics to appear in France since 1671, and generated heated debate. In the Institutions de Physique, Du Châtelet innovatively combined metaphysics and physics, creating a work that is not merely a textbook on natural philosophy, but made important contributions to the philosophy of science. Moreover, the considerable influence of this work on later Enlightenment thinkers, both in France and abroad, is well documented. She is the first author to reconcile strong Leibnizian and Wolffian rationalist roots with the newly discovered Newtonian laws of physics. In line with this, the account of knowledge presented in the Institutions de Physique is based on absolute and a priori principles of knowledge and on experience. Unlike the dominant conception of first principles as innate principles in the rationalist tradition, she emphasises their role in our experiential knowledge in physics and conceives of them as principles of beings themselves. In the manuscript, which can be found in Paris, she reorganised larger parts of her text by focusing more specifically on Leibniz, Wolff and a philosophical foundation of physics. In the 1742 printed edition, an especially intriguing change is that she made her authorship as a female author public, by inserting the feminisation of the endings of the verbs. The most interesting changes, however, are in the later chapters, where Du Châtelet revised the parts on Newton and gravitation and added the letter exchange with Mairan.

Correspondence with M. de Mairan (1741)

Both the letter from Dortous de Mairan and the reply from du Châtelet have been preserved. In his dissertation (1728) Disseration sur l’estimation et la mesure des forces motrices des corps, Mairan claimed that he settled the living forces dispute. Du Châtelet, however, disagreed and made some objections to Mairan’s theory in her Institutions de physique, especially in chapter XXI. The letters take up this discussion. In the midst of this controversy, in April 1741, Voltaire presented a paper at the Académie des Sciences (“Doutes sur la mesure des forces motrices et sur leur nature”), basically taking Mairan’s side.

Report on living forces presented in the form of a letter to M. Jurin (1747)

James Jurin was in a lengthy debate over the interpretation of Newton’s limits and fluxions with some other British Newtonians, namely Robins and Pemberton. This was prompted in part by Berkeley’s criticisms of calculus in his Analyst. Part of this debate came down to questions of how to translate or understand specific Latin phrases in Newton’s Principia, such as “fiunt ultima aequales.” “Du Châtelet’s first contact with James Jurin, the eminent English mathematician, had come through Maupertuis. In 1738, he had arranged for Algarotti to take a copy of her Dissertation sur la nature du feu to Jurin on his trip to London. Du Châtelet herself sent him her response to Mairan’s criticism in February 1741. That summer, Jurin complimented her in a letter to Voltaire […] Jurin had already responded to Du Châtelet’s critique of his hypothetical boat in chapter XXI. […] The final version ran to five pages and gave the reasoning and the mathematics in great detail. Du Châtelet sent it to Jurin with the second edition of the Institutions” (see Judith P. Zinsser, Emilie du Châtelet: Daring Genius of the Enlightenment, Penguin Books, 2007, p. 209). In turn, Florian Cajori has argued that Du Châtelet’s translation of the Principia tacitly supports Jurin’s interpretation of fluxions in this controversy.

[This work contains texts in Latin, French and Italian; Châtelet’s letter to Jurin is signed from Cirey, 30 May 1744]

Translation of Newton’s Principia (1749)

In the 1740s, the Marquise du Châtelet translated Newton’s Principia (1731, third edition) into French. Hers remains the standard translation. In addition, she wrote an extensive commentary in which she gave her own description of the System of the World, and analytical solutions to key disputed aspects of Newton’s theory of universal gravitation. She also included summaries of two mathematical essays that clarified and confirmed Newton’s application of his theory to observed phenomena: Aléxis–Claude Clairaut’s on the shape of the Earth and Daniel Bernoulli’s on the effects of the Sun and Moon on the tides.

Discours sur le bonheur (1779)

The ‘Discours’ was probably written around 1746 and published posthumously in 1779. It is her only personal work, in which she follows in the footsteps of great predecessors on this theme like Lucretius, Pascal and Seneca. In this work, combining intellectual, sentimental and even sensual experiences, Du Châtelet traced the balance of her personal ambitions, her love affair with Voltaire and her hopes, in an attempt to answer questions that haunted her time: “How can one be happy on this earth, and more particularly how can one be happy when one is a woman who, even if exceptional, is forbidden most of the ambitions and glories permitted to men? How to be happy when you are a passionate, exclusive and tyrannical lover?,” as Elisabeth Badinter writes in her Preface.

Examens de la Bible

Around 1742, Du Châtelet wrote a devastating commentary on the Old and New Testaments, which she was careful to leave unseen and unpublished. It remained unknown for a long time: even Voltaire never dared to publish it. Recently, Schwarzbach’s complete, annotated edition has been published, along with Zinsser and Bour’s partial English translation. Even Schwarzbach’s edition, however, is based on three manuscripts whose origin remains unknown. Their history can only be traced from dates well after her death in 1749. The manuscript on which Schwarzbach’s edition is based belonged to Countess Marie-Thérèse le Pellerin de Gauville in the 19th century. The second manuscript, consisting of 5 volumes in 16°, has been in the Bibliothèque municipale de Troyes since 1855 and the third in the Bibliothèque royale de Bruxelles, probably since 1815. The Examinations of the Bible shows a ruthless binary logic and, in its impiety, also has its paradoxes: the work draws almost exclusively on pious or learned sources, evoking neither the free thinkers of the 17th century nor the “clandestine philosophers”.

Translation with commentary and Preface of Mandeville’s The Fable of the Bees

Around 1735, Du Châtelet began a translation of selections from Bernard Mandeville’s Fable of the Bees, originally written in English. This translation was not published in her lifetime, but like her biblical commentary was circulated clandestinely in Enlightenment circles. Her translation significantly modifies the original and adds a number of ideas that differ significantly from Mandeville’s; Du Châtelet explicitly differentiates these additions from verbatim translations of Mandeville. As Judith Zinsser has put it, with this translation Du Châtelet “created a book of ethics that is very much her own work” (Emilie Du Châtelet: Selected Philosophical and Scientific Writings, 2009, 36). There is also a noteworthy “Translator’s Preface” in which Du Châtelet not only lays out her views on translation, but also considers the challenges faced by women intellectuals of the eighteenth century. She writes, for example, of “the full weight of prejudice that excludes” women “so universally from the sciences” (Selected Writings, 48). Three distinct manuscript versions of the translation survive among Du Châtelet’s St. Petersburg papers.

Essai sur l’Optique

Sometime in the late 1730s, Du Châtelet composed a never-published essay on optics. Du Châtelet treats such topics as light, the nature of transparent and opaque bodies, and the theory of colours. She engages with the work of Huygens, Newton, Mairan, and Fermat, among others. Multiple manuscript versions of the work exist, though not all are publicly available. The extant complete edition is based on the so-called Basel manuscript, which was found in the Basel Bernoulli archives.

[Wade publishes just one chapter of the Essai, Chapitre IV, which is concerned with colors. Wade follows the St. Petersburg manuscript rather than the Basel Manuscript]


De la Liberté

This short essay has a complex history. Voltaire sent it to Frederick of Prussia, claiming that he had written it, and the work is still most easily available in the standard edition of Voltaire’s works. However, an examination of the manuscript shows extensive revisions in Du Châtelet’s hand, as well as cross-references to numerous specific sections of Du Châtelet’s Institutions de Physique. The current scholarly consensus is that the work was written in the late 1730s as a chapter of the Institutions—it is labeled as “Chap. 5”—but was ultimately not included. In any case, the essay is philosophically significant, delving in depth into Du Châtelet’s conception of human and divine freedom.

Grammaire Raisonée

A few chapters of a general grammar have been found among Du Châtelet’s St. Petersburg manuscripts. The date of composition is unknown. The surviving chapters seem to form the middle of a larger work. They deal primarily with words and their signification: both at a general level, and for more specific categories of word, such as articles, comparatives, pronouns, and substantives.

Translation of extracts of Woolston’s Discours

This summary extract of Thomas Woolston’s work on Jesus’s miracles was recently discovered in St. Petersburg. Trapnell, the editor of the modern edition of these extracts, argues that they were not intended for publication. They may instead be notes connected to the broader project of Du Châtelet’s Examens de la Bible. Schwarzbach has argued (e.g. in “Les études bibliques à Cirey,” 2017) that Woolston’s work was a source both for the Examens and for Voltaire’s parallel project in biblical criticism (the Bible enfin expliquée, eventually published in 1776).
