Au milieu du XVIIIe siècle, le pouvoir et la censure exercés par l’État et l’Église étaient très bien connus par Denis Diderot. Incarcéré en 1749 pour la publication de son texte <em>La Lettre sur les aveugles à l’usage de ceux qui voient</em>, et persécuté sans cesse pour son travail sur <em>L’Encyclopédie</em>, Diderot cherchait un moyen d’exprimer sa philosophie matérialiste et d’éviter la prison. Dans <em>Le Rêve de D’Alembert</em> et <em>Le Neveu de Rameau</em>, écrits entre 1762 et 1773, le philosophe a trouvé ce moyen dans les monstres, et il a utilisé la monstruosité physique ainsi que morale comme outils littéraires. Les monstres sont employés de manière didactique, afin d’instruire le lecteur et d’élucider ses idées sur la nature, la biologie, le matérialisme, et même certains aspects de la philosophie athée. L’hybridité associée avec la monstruosité a même influencé la forme de ces deux dialogues, qui sont des œuvres uniquement structurées pour véhiculer leurs messages. À partir d’une analyse du <em>Rêve de D’Alembert </em>et du <em>Neveu de Rameau</em>, ainsi qu’une étude des textes critiques, cette thèse démontre comment la monstruosité est devenue un élément-clé dans l’expression de la philosophie matérialiste de Diderot. / Master of Arts (MA)

Le « clair-obscur », tirant son origine du terme italien « chiaroscuro », est considéré comme l’un des plus importants éléments dans l’art et la littérature. En examinant dans les tableaux la lumière et les ombres, deux composants opposés, les peintres ainsi que les critiques d’art du XVIIe et du XVIIIe siècles font preuve d’un grand enthousiasme de dévoiler leurs secrets. L’instauration de l’Académie, le grand débat sur le colorisme et la naissance de la critique d’art en France sont des occasions particulières pour approfondir leurs études du clair-obscur.Parmi les critiques d’art du XVIIIe siècle, c’est Diderot qui souligne les effets du clair-obscur dans ses Salons. Par rapport à d’autres salonniers contemporains, seul Diderot philosophe-écrivain expose ses propres idées esthétiques concernant le clair-obscur et transmet ses effets poétiques aux lecteurs, en suscitant de fortes « émotions ». Cette originalité littéraire des Salons contribue donc à l’évolution de la critique d’art des siècles suivants. / The « clair-obscur », from the Italian term « chiaroscuro », is considered one of the most important elements in art and literature. By examining the two opposing components of light and shadow in paintings, the painters and art critics in the seventeenth and eighteenth centuries show great enthusiasm about revealing their secrets. The establishment of “Academy”, the great discussion on coloration and the birth of art criticism in France are special opportunities for further study of chiaroscuro.Among the art critics of the eighteenth century, it is Diderot who emphasizes the effects of chiaroscuro in his Salons. Compared with other contemporary « salonniers », only Diderot as a philosopher and writer, exposes his own aesthetic ideas regarding chiaroscuro and passes on the poetic effects of this to his readers, arousing strong « emotions ». This literary originality of the Salons contributes thus to the development of art criticism in the following centuries.

Este estudo visa sondar a presença de autores franceses setecentistas ligados às Lumières no universo das crônicas de Machado de Assis. Popularizados, sobretudo, graças à imprensa, força motriz na disseminação do conhecimento no início do século XIX, Voltaire, Rousseau e Diderot, destituídos da aura de grandes filósofos, integram-se facilmente na esfera do folhetim. Ali, obras, temas e princípios criados por eles (já decantados pela cultura popular e tornados clichês, axiomas e ditos) agregam sentidos, ampliam a compreensão do elemento local, concorrem para a característica irônicochistosa do gênero e sedimentam a relação Brasil-França através da poética intertextual, traço profundo da escrita machadiana, cuja pluralidade de vozes fez da crônica um diálogo particular entre os dois países. A crítica moderna nos adverte quanto ao maniqueísmo da esquematização, ressaltando o lado arbitrário de toda periodização. Nota-se, contudo, que ao olhar o passado recente na tentativa de compreender o século XVIII, os homens do XIX retomaram em parte imagens herdadas da autorrepresentação daquele que foi o século da audácia crìtica, de maneira que se pode isolar o século XVIII, pois, mitificado, impõe-se ainda como identidade específica, irradiando a cultura francesa através de Voltaire, Rousseau e Diderot, seus exponenciais mitos mobilizadores. / This study aims, above all, at scrutinizing the presence of French writers from the eighteenth century, related to the Lumières, in the universe of Machado de Assis\'s chronicles. Popular, especially due to the press driving force in the dissemination of knowledge in the beginning of the nineteenth century Voltaire, Rousseau and Diderot, destitute of the great philosophers aura, easily fit into the universe of the broadsheet, where works, themes and principles created by them (which no longer enchanted the popular culture and had become clichés, axioms and sayings) were able to attribute meanings, broaden the understanding of the local element, compete for the mockingironic characteristic of the genre and strenghten the Brazil-French relationship through intertextual poetics deep feature of Machados writings, whose plurality of voices turned the chronicles into a particular dialogue between the two countries. Modern criticism advises us about the manichaeism of scheming, by highlighting the arbitrarity side of periodization. However, by looking at the recent past while trying to understand the eighteenth century, it is possible to notice that those men from the nineteenth century resumed, in part, the images inherited from the selfrepresentation of the century which was the time for the critical audacity, so as that one can isolate the eighteenth century, since, mythified, it also imposes itself as a specific identity, irradiating the French culture through Voltaire, Rousseau and Diderot, its exponential moving myths.

Des Lumières au réalisme, le médecin prend une place toujours plus importante dans la littérature. Si sa discipline évolue et connaît ainsi de considérables progrès, sa représentation dans la fiction devient elle aussi conséquente. De ce fait, le roman s'empare de ce personnage pour lui conférer un rôle de témoin actif des changements historiques et esthétiques, à travers trois domaines : la politique, la spiritualité et les passions. En effet, s'il diagnostique les maladies du corps social, les pathologies que manifeste l'Histoire, il est aussi appelé à sonder les âmes pour déterminer les causes du désarroi intérieur de l'être humain. Derrière la physiologie et l'anatomie, il explore également les arrière-mondes de la foi et des sentiments. Le praticien se doit donc d'éclairer les mystères de la condition humaine. / From the Enlightenment to realism, the doctor acquires an increasingly important place in French literature. With the development and considerable progress of medical science, the fictional doctor also becomes consequential. Hence, the novel calls upon this character to play an active role as witness of the historical and aesthetic changes in three fields: politics, spirituality and passions. In fact, not only does he diagnose the diseases of the social body, the pathologies that History reveals, he is also called upon to sound souls in order to establish the causes of the inner disarray of the human being. Behind the physiology and anatomy, he also explores the afterworldly for faith and feelings. The practitioner must therefore throw light on the mysteries of the human condition.

Ce travail interroge la valeur du syntagme « expérience de pensée » rapporté aux textes de philosophie et d’histoire naturelle du dix-huitième siècle. La prégnance de ce syntagme, tant dans la littérature critique que dans son usage oral spontané ne doit pas occulter sa quasi-absence littérale au XVIIIe siècle, qui lui préfère d’autres noms : l’« investigation » rousseauiste, le « problème » de Molyneux ou les « expériences philosophiques » de Mérian. C’est donc le besoin de trouver le lien manquant entre cette quasi-absence littérale et cette volonté commune de caractériser conceptuellement certains procédés dix-huitiémistes en « expériences de pensées » qui motive notre recherche. À travers un corpus étendu mais représentatif (Lamy, Locke, Fontenelle, Condillac, Buffon, Rousseau, Diderot, Mérian, Fortis) nous analysons les procédés qui légitiment ou non le recours à l’expérience de pensée, en spécifiant les textes par une typologie nouvelle, fondée sur le rapport aux concepts de nature et de possibilité. À partir d’une étude générale du concept d’expérience de pensée, nous analysons son emploi à la charnière des XVIIe et XVIIIe siècles, par le renouveau des arts de bien penser et parler, puis à travers son importance dans les discussions scientifiques et philosophiques. Nous procédons à l’application typologique de ce qu’il nous semble nécessaire de nommer des espèces de l’expérience de pensée (imaginaire, hypothétique ou conjecturale, projective et extravagante) afin de mettre en évidence les ressorts connus du procédé, à savoir son scénario, sa vocation cognitive et son usage de l’imagination, tout en proposant d’autres données conceptuelles du travail d’écriture et de lecture de l’expérience de pensée : la place conférée à la fiction, l’usage des personnages et la fonction d’un lecteur capable d’expérimenter en pensée de manière rigoureuse et ludique. / This work questions the value of the phrase “thought experiment” related to the texts of philosophy and natural history of the eighteenth century. The importance of this phrase, both in critical literature and in its spontaneous oral use, should not overshadow its literal quasi-absence in the eighteenth century, which prefers other names: Rousseau’s “investigation”, the “problem” of Molyneux or the “philosophical experiments” of Merian. It is thus the need to find the missing link between this quasi-literal absence and this common desire to characterize conceptually certain eighteenth-century processes in “thought experiments” that motivates our research. Through an extensive but representative corpus (Lamy, Locke, Fontenelle, Condillac, Buffon, Rousseau, Diderot, Mérian, Fortis) we analyze the processes that legitimize or not the use of thought experiment, by specifying the texts by a new typology, based on the relationship to the concepts of nature and possibility. Based on a general study of the concept of thought experience, we analyze its use at the turn of the 17th and 18th centuries, through the renewal of the arts of thinking and speaking well, and then through its importance in scientific and philosophical discussions. We proceed to the typological application of what it seems necessary to name species of the thought experiment (imaginary, hypothetical or conjectural, projective and extravagant) in order to highlight the known springs of the process, namely its scenario, its cognitive vocation and its use of the imagination, while proposing other conceptual data of the work of writing and reading the thought experiment: the place conferred on fiction, the use of characters and the function of a reader able to experiment in thought in a rigorous and playful way.
