ABSTRACTMaterialism is the view that everything that is real is material or is the product of material processes. It tends to take either a ‘cosmological’ form, as a claim about the ultimate nature of the world, or a more specific ‘psychological’ form, detailing how mental processes are brain processes. I focus on the second, psychological or cerebral form of materialism. In the mid-to-late eighteenth century, the French materialist philosopher Denis Diderot was one of the first to notice that any self-respecting (...) materialist had to address the question of the status and functional role of the brain, and its relation to our mental life. After this the topic grew stale, with knee-jerk reiterations of ‘psychophysical identity’ in the nineteenth-century, and equally rigid assertions of anti-materialism. In 1960s philosophy of mind, brain–mind materialism reemerged as ‘identity theory’, focusing on the identity between mental processes and cerebral processes. In contrast, Diderot’s cerebral materialism allows for a more culturally sedimented sense of the brain, which he described in his late Elements of Physiology as a ‘book – except it is a book which reads itself’. Diderot thus provides a lesson for materialism as it reflects on the status of the brain, science and culture. (shrink)

Les interprétations habituelles de l’article «Éclectisme» de l’Encyclopédie mettent l’accent sur l’idée que Diderot y annonce le programme de la philosophie moderne, dont il se ferait par le fait même un illustre représentant et l’un des promoteurs. Dans cet article, j’essaie de compléter cette interprétation en montrant que l’article est également porteur d’une réflexion de premier plan sur l’histoire de la philosophie, sur les effets de continuité dans sa pratique et, conséquemment, sur ce qui est proprement constitutif du discours philosophique (...) lui-même, tant sur le plan méthodologique qu’en ce qui conc erne son positionnement politique. -/- The standard interpretation of Diderot’s article “Éclectisme” in the Encyclopédie emphasizes the idea that Diderot is setting out the program for modern philosophy, thereby making himself its illustrious representative and promoter. In thispaper, I complement this interpretation by showing that “Éclectisme” also contains an influential reflection on continuity in the history of philosophy and, consequently, on what constitutes philosophical discourse itself, both methodologically and politically.

Intellectual history still quite commonly distinguishes between the episode we know as the Scientific Revolution, and its successor era, the Enlightenment, in terms of the calculatory and quantifying zeal of the former—the age of mechanics—and the rather scientifically lackadaisical mood of the latter, more concerned with freedom, public space and aesthetics. It is possible to challenge this distinction in a variety of ways, but the approach I examine here, in which the focus on an emerging scientific field or cluster of (...) disciplines—the ‘life sciences’, particularly natural history, medicine, and physiology —is, not Romantically anti-scientific, but resolutely anti-mathematical. Diderot bluntly states, in his Thoughts on the interpretation of nature, that “We are on the verge of a great revolution in the sciences. Given the taste people seem to have for morals, belles-lettres, the history of nature and experimental physics, I dare say that before a hundred years, there will not be more than three great geometricians remaining in Europe. The science will stop short where the Bernoullis, the Eulers, the Maupertuis, the Clairauts, the Fontaines and the D’Alemberts will have left it.... We will not go beyond.” Similarly, Buffon in the first discourse of his Histoire naturelle speaks of the “over-reliance on mathematical sciences,” given that mathematical truths are merely “definitional” and “demonstrative,” and thereby “abstract, intellectual and arbitrary.” Earlier in the Thoughts, Diderot judges “the thing of the mathematician” to have “as little existence in nature as that of the gambler.” Significantly, this attitude—taken by great scientists who also translated Newton or wrote careful papers on probability theory, as well as by others such as Mandeville—participates in the effort to conceptualize what we might call a new ontology for the emerging life sciences, very different from both the ‘iatromechanism’ and the ‘animism’ of earlier generations, which either failed to account for specifically living, goal-directed features of organisms, or accounted for them in supernaturalistic terms by appealing to an ‘anima’ as explanatory principle. Anti-mathematicism here is then a key component of a naturalistic, open-ended project to give a successful reductionist model of explanation in ‘natural history’, a model which is no more vitalist than it is materialist—but which is fairly far removed from early modern mechanism.

In this article I address the issue of the ontological conditions of possibility for a naturalistic notion of emergence, trying to determine its fundamental differences from the atomist, vitalist, preformationist and potentialist alternatives. I will argue that a naturalistic notion of ontological emergence can only succeed if we explicitly refuse the atomistic fundamental ontological postulate that asserts that every entity is endowed with a set of absolutely intrinsic properties, being qualitatively immutable through its extrinsic relations. Furthermore, it will be shown (...) that, ironically enough, this metaphysical assumption is implicitly shared by all the above mentioned alternatives to Emergentism. The current article concludes that the notion of organization by itself is not enough, and that ontological emergence can only be justified by assuming a relational ontological perspective that, in opposition both to atomism and holism, defends that the existence-conditions, the identity and the causal behavior of any emergent systemic property can only be conceived, and explained, as constructed by and through specific networks of qualitatively transformative relational processes that occur between the system’s components and between the system and its environment. Additionally, I try to explain how one can make sense of the idea that an emergent phenomenon is both dependent on, and autonomous from, its emergence base. (shrink)

ArgumentEighteenth-century Montpellerian vitalism and contemporaneous French “vitalist” materialism, exemplified by the medical and biological materialism of La Mettrie and Diderot, differ in some essential aspects from some later forms of vitalism that tended to postulate immaterial vital principles or forces. This article examines the arguments defending the existence of vital properties in living organisms presented in the context of eighteenth-century French materialism. These arguments had recourse to technological metaphors and analogies, mainly clockworks, in order to claim that just as machines (...) can have functional properties which its parts do not possess, so living organisms can, as material entities, also have organic or vital properties which its material parts do not possess. Such arguments, with the help of a healthy dose of epistemological scepticism, tend to strike a balance between two positions concerning the ontology of life which we now tend to label “vitalism” and “emergentism.” Although there is nothing inconsistent in viewing vital properties as emergent, some ambiguity results if one does not draw a clear distinction between properties and functions. The philosophical problems related to these ambiguities are revealed in Diderot's apparent hesitation concerning sentience as “a general property of matter or the product of organization.”. (shrink)

Résumé Cet article aborde la querelle comme un élément de la stratégie d’un philosophe vis-à-vis de la postérité. On pourrait évidemment penser à des querelleurs invétérés comme Pascal, Voltaire ou Rousseau, mais il sera question ici du cas plus complexe de Diderot et du dernier ouvrage publié de son vivant, l’_Essai sur les règnes de Claude et de Néron et sur les moeurs et les écrits de Sénèque pour servir à l’introduction de la lecture de ce philosophe_ (1782). L’article démontre (...) que celui-ci constitue un cas de « texte-querelle », c’est-à-dire un texte qui met en scène la querelle menée à son propre sujet et qui ainsi la fait redémarrer; il analyse la posture qu’adopte le philosophe-querelleur, surtout dans l’énoncé paradoxal « ne nous engageons point dans les querelles », dont il examine les qualités performatives.

Que veut dire « vivre de sa plume»? L'expression a souvent été invoquée par des historiens avançant le récit d'un progrès dans les pratiques littéraires marqué par le passage des écrivains du patronage au marché, afin de définir la « modernité » auctoriale par rapport à un modèle ancien de l'homme de lettres protégé par la noblesse. Or un examen plus attentif montrera que ce progrès vers une autonomie gagnée par la vente des écrits n'est guère aussi évident qu'on a (...) eu tendance à le croire. Cet article étudie donc les ambiguïtés du récit historique implicite dans la notion de « vivre de sa plume ». Il propose ensuite une approche différente qui considère cette représentation non pas comme le reflet d'une nouvelle réalité professionnelle, mais comme un élément dans une nouvelle rhétorique de la présentation de soi en tant qu 'intellectuel. Comme topos, l'image va désigner - et en fait, constituer - à la fois la libération sociale de l'auteur à l'égard de la noblesse et son autorité morale lorsque ses tentatives de vivre de ses écrits échouent et qu'il persiste tout de même à sacrifier son bonheur personnel à son art.

This paper deals with a development of the ancient thought on mimesis in its modern reception as regards a certain idea of theatre. It defends the hypothesis that the figure of the character, as set up in Diderot’s Paradoxe sur le comédien, has its source in a curious reversal of the Platonic mimesis. After presenting the main tenets of Plato’s reflection on mimesis and of Diderot’s theory on character, showing their convergences and contrasts, it is analyzed how such a conceptual (...) turnaround has historically taken place, by establishing a chain of reception from Plato to Diderot passing through Cicero and the Renaissance artists.

If research devoted to the clandestine literature of the seventeenth and eighteenth centuries is today enjoying considerable expansion in the scholarly world, it tends, nonetheless, to be restricted to materialist considerations. However, other themes are open to exploration, such as the immaterialist one which is explicitly mentioned in two manuscripts (theRéflections morales et métaphisiques sur les religions et sur les connoissances de l'hommeand theJordanus Brunus Redivivus). After presenting and analyzing these two texts, we argue that this clandestine account of immaterialism (...) could explain both the evolution of this theory during the Enlightenment and the misunderstanding of Berkeley's philosophy.

In selected texts by Diderot, including the Encyclopédie article “Cabinet d’histoire naturelle” (along with his comments in the article “Histoire nat-urelle”), the Pensées sur l’interprétation de la nature and the Salon de 1767, I examine the interplay between philosophical naturalism and the recognition of the irreducible nature of artifice, in order to arrive at a provisional definition of Diderot’s vision of Nature as “une femme qui aime à se travestir.” How can a metaphysics in which the concept of Nature has (...) a normative status, also ultimately consider it to be something necessarily artificial? Historically, the answer to this question involves the project of natural history. A present-day reconstruction would have to make sense of this project and relate it to the vision of Nature expressed in Diderot’s phrase. In addition, it would hopefully pinpoint the difference between this brand of Enlightenment naturalism and contemporary naturalism, and by extension, allow us to understand a bit more about what naturalism is in general.

The purpose of this article is to show how the use of certain terms of theatre, that are employed to describe philosophical procedures or concepts, reveals two different kinds of relations between philosophical discourse and artistic practices: On the one hand, some philosophers make a conscious and metaphorical use of the vocabulary of scenic practices to describe their own operations; on the other, the technical and historical determinations of these practices open up new interpretations of philosophical constructs, even though, at (...) first, they were not intended to do so by the authors that exploit them. To fulfil this purpose, this article analyzes significant moments of contemporary French thought—where there are frequent expressions such as scene and dramaturgy—, in order to trace the genealogy of that philosophical interest and explore a series of descriptions of the theory and practice of classical French theatre.

This paper focuses on the link between systems criticism and anti-mathematicism in the French-speaking philosophical literature of the mid-18thcentury. Moving from Condillac’s omissions to the exemplary cases of Diderot and Buffon—as well as considering Formey’s crucial remarks—I reconsider the complex relationship that the authors of the French Enlightenment have with the Newtonian model. Finally, I inquire into the fate awaiting both mathematics and systems in this context after 1750.

This article examines the relationship between blindness and the Enlightenment concept of the system, arguing that blindness is used as a weapon to discredit 17th-century metaphysics, as well as a tool through which thought can take shape or even systematize itself apart from dogmatism. Philosophers use blindness metaphorically, thus equating systematics within the obscurity of ignorance; yet, with Diderot, they also demonstrate that philosophy, for better or for worse, is literally an affair of blindness.
