Before and After Vincennes

Rousseauâs Chemical
Apprenticeship1
Christopher Kelly
The temptation to divide Rousseauâs life into a âbeforeâ and âafterâ is irresistible. There are, in fact, numerous candidates for the turning point: his decision to run away from Geneva when he was fifteen, his decision to pursue fame and fortune in Paris when he was thirty, or his flight from France and subsequent persecution after the publication of Emile when he was fifty. Each of these is dramatic enough and Rousseau makes much of each of them; but, for most students of his thought, the authentic turning point is the famous âilluminationâ on the road to Vincennes in 1749. Rousseauâs most complete description of this moment, in the second of the âLetters to Malesherbesâ written in 1762, is particularly vivid in its account of a rupture from the past. Rousseau compares the illumination to a âsudden inspirationâ accompanied by âa thousand lights,â âinexpressible perturbation,â âdizziness similar to drunkenness,â and âviolent palpitation.â2
This illumination represents a crisis in Rousseauâs life that was intensely personal. The insights contained in it also led to a crisis in modern thought and life under Rousseauâs withering scrutiny. Rousseauâs consequent decision to write works based on the insights acquired so suddenly turned him from a little known secretary into a famous writer almost overnight. In little more than a decade, Rousseau published the First and Second Discourses, The Village Soothsayer, Julie, Emile, and the Social Contractâto mention only his most notable works. Among authors, only Voltaire, whose string of successes had begun decades earlier, rivaled his fame. Given the suddenness and durability of this change in Rousseauâs life, it hardly seems an exaggeration for him to describe it by saying, âI saw another universe and became another man.â3
Rousseauâs own emphasis on this moment and the prominence of the writings that came from it have led to a fairly uniform view of his career, even among scholars who evaluate his work in different ways. It is customary to refer to the writings that were published in the years immediately following the illumination as early writingsâas if he had written nothing before.4 Thus the First and Second Discourses are considered early writings, and the Social Contract and Emile are regarded as late. This framework has its uses, but it can be misleading. Rousseau wrote all of these works over a quite short period of timeâlittle more than a decade. He often worked on several at a time, some of which he published right away and others of which he took time to finish. Why is a work published in 1755 an early work and one begun earlier but published a few years later a late work? Rousseau always insisted that these writings formed a unified whole. Furthermore, calling the Discourses early works neglects the fact that Rousseau was thirty-eight when he published the first of these.
This does not mean, of course, that little attention is paid to Rousseauâs life before the illumination. Indeed, there are few major thinkers whose childhood experiences and feelings have been subject to as much scholarly attention. The unprecedented candor of the account of these experiences and feelings given in the Confessions has been a strong stimulus for psychologically oriented accounts of Rousseauâs life. Those who direct their attention to Rousseauâs life before the illumination tend to diminish the profundity of his mature thought by seeing it as the ultimate expression of deep-seated conflicts rooted in childhood experience; whereas those who attempt to demonstrate the depth of his thought avoid considering what he did before the illumination. In short, the division of Rousseauâs life into two halves encourages a view that the first half was one of intense feeling and variety of experiences accompanied by little thought and that the second was one of deep thought that either did or didnât free itself from youthful feelings.
Rousseauâs apparent authorization of this characterization of the division in his life is hardly absolute, however. His more nuanced view of the matter becomes clearer when one looks at things he wrote near the period of the illumination. For example, in the âFinal Reply,â written in 1752 in response to one of the many attacks on the First Discourse, Rousseau complains about the superficiality of those writers who hastened to oppose him saying, âBefore explaining myself, I meditated on my subject at length and deeply, and I tried to consider all aspects of it.â5 A few years later, in reviewing the controversies in which he had been involved, he elaborates on this, saying, âI wondered how anyone could write with so little discretion and no reflection about matters that I had meditated about almost my whole life without having been able to clarify them adequately, and I was always surprised not to find in my adversariesâ writings a single objection that I had not seen and rejected in advance as unworthy of attention.â6 In describing the period before the Discourse, he says, âI was active because I was foolish; to the extent that I was undeceived I changed tastes, attachment, projects, and in all these changes I always wasted my effort and my time because I was always looking for what did not exist.â7 He does not, however, say that he had not had a single thought in his head; he indicates confusion, not total ignorance. Looking at the illumination as a beginning pointâwhich it surely was in some senseâobscures the fact that it was also a conclusion: a period of confusion came to a close and was replaced with clarity. In these passages Rousseau indicates that he had long struggled prior to the illumination with precisely the issues that he addressed in the Discourse and subsequent writings. This evidence does not contradict the later accounts, but it does indicate that the result of the illumination was not the sudden awareness of these important issues, but rather the sudden solution to questions that had plagued Rousseau for a long time. The purpose of this essay is to call attention to one set of these issues centering on a sustained encounter with modern natural science. Rousseauâs mature critique of modernity was preceded by a sustained absorption with one of modernityâs proudest claims: its aspiration to scientific knowledge.
I
Since the publication of the Discourse on the Sciences and the Arts, Rousseau has been regarded as a critic of the sciences. Even in the case of the one science with which he is closely associated, namely botany, his best-known discussions sharply distinguish this science from other natural sciences such as physics and chemistry.8 In particular, his praise of the pleasant activity of botanizing outdoors is contrasted to the âtedious and costly experimentsâ necessary for chemistry, experiments that require spending âmoney and time in the midst of charcoal, crucibles, furnaces, retorts, smoke and suffocating fumes, always at the risk of life and often at the expense of health.â9 It is not often noticed that this and other attacks on chemistry show that Rousseau was well acquainted with the activity he is criticizing. Indeed, earlier in his life he engaged in an extensive period of study of chemistry and had considerable experience with crucibles, furnaces, retorts, and all that their operations entailed.
Until the recent publication of two separate scholarly editions of the Institutions chimiques, little attention had been paid to Rousseauâs writings on chemistry.10 Indeed, the Institutions was not included in the standard PlĂŠiade edition of Rousseauâs works, even though the final volume included other scientific works written around the same time or even earlier. The editors apparently regarded the Institutions as a work of mere compilation, which, if it had been completed, might have appeared as the work of Rousseauâs employer rather than his own.11 Rousseau entrusted this work, over 1,200 pages in manuscript and accompanied by numerous shorter essays, to one of his literary executors, Pierre Moultou, in 1778, and it was handed down through Moultouâs family. The manuscript was discovered by scholars toward the end of the nineteenth century and was published successively between 1919 and 1921. Even this publication stimulated little interest. The new editions of the Institutions allow the status of this work to be reevaluated.
Book VII of the Confessions discusses the circumstances leading to the composition of the Institutions. Rousseau had been exposed to chemistry in the 1730s when he lived with Mme. de Warens. She combined botany and chemistry with the production of herbal remedies, but Rousseau claims that he did not develop a taste for these studies at that time. The one episode he does recount of performing an experiment involved an attempt to make sympathetic ink, which blew up in his face and blinded him for more than six weeks.12 Book VII begins with Rousseauâs arrival in Paris in the middle of 1742 filled with hopes for success based on his system of musical notation and a draft of his play Narcisse. When neither of these was warmly received, he was left with the resource of some letters of recommendation, one of which was to the Jesuit priest Louis Bertrand Castel. The Jesuit urged Rousseau to turn away from scholars and academies, saying, âOne does nothing in Paris except by means of women. They are like the curves of which wise men are the asymptotes; they ceaselessly approach them but they never touch them.â13 Castel obtained entry for Rousseau into a few households, including that of Louise-Marie-Madeleine Dupin, the wife of the tax farmer Claude Dupin, whose son by an earlier marriage, Charles-Louis Dupin de Francueil, was several years younger than Rousseau. Rousseau formed a friendship with Francueil on the basis of their mutual love of music, and, in the spring of 1743, they took a course in chemistry with Guillaume-François Rouelle, the leading French chemist of his day and later a teacher of Lavoisier among others.14 Some months later Rousseau left Paris to take the position as secretary to the French ambassador to Venice. After a tempestuous stay in Venice, during which he used his knowledge of chemistry to perform magic tricks (apparently using sympathetic ink),15 he returned to Paris in the autumn of 1744 and eventually responded to Francueilâs offer of employment as one of his and his stepmotherâs secretaries. Rousseau entered their employ because he was desperate for a steady, if small, income. His correspondence indicates that he had maintained an interest in chemistry.
Rousseau explains Francueilâs desire for a secretary by saying, âM. de Francueil was studying natural history and chemistry at that time and was making a collection. I believe that he aspired to the Academy of Sciences: for that purpose he wanted to write a book, and he judged that I could be useful to him in this labor.â16 Accordingly, the two friends resumed their studies with Rouelle and took several of his courses.
