Le constat que fait Spinoza dans le Traité de la réforme de l ’ entendement selon lequel on ne connaît ses parents que par ouï-dire fournit l’occasion de développer, à partir de l’exemple de la famille, la conception originale qu’offre le point de vue spinoziste sur les institutions. En reprenant une distinction que fait Julie Henry, on peut dire que la famille n’existe pas par nature, mais qu’elle est un effet naturel. L’univocité de la causalité et la diversité des causes (...) qui président à sa constitution permettent d’échapper à l’opposition nature – culture comme à toute tentative de réduire les phénomènes sociaux à des principes biologiques ou environnementaux.

Towards the middle of the 18th century, Pierre-Louis Moreau de Maupertuis proposed the “principle of least action” as a fundamental law of physics and as a proof of the existence of God. Samuel König and other contemporary authors criticized Maupertuis’ work. There ensued a fierce discussion concerning this subject, in which Leonhard Euler, the king Frédéric II of Prussia and Voltaire took part. This paper discusses that debate, emphasizing its extrascientific features and analyzing the interests that motivated the (...) actions of the people involved in that episode. RESUMO: Em meados do século XVIII, Pierre-Louis Moreau de Maupertuis propôs o “princípio de ação mínima”, que seria uma lei fundamental da física, além de constituir uma prova da existência de Deus. O trabalho de Maupertuis foi criticado por Samuel König e outros autores da época. Ocorreu uma violenta discussão a respeito desse assunto, da qual participaram Leonhard Euler, o rei Frédéric II da Prússia e Voltaire. Este artigo estuda o debate ocorrido, enfatizando especialmente os aspectos extracientíficos e analisando os interesses que motivaram as ações das pessoas envolvidas nesse episódio. (shrink)

The perpetual secretary of the Berlin Academy Johann Heinrich Samuel Formey is best known as a populariser of Christian Wolff’s doctrines. As of Formey’s activity in the Berlin Academy, scholars have mostly emphasized his role in the controversy over monads with Leonhard Euler, while overlooking other interesting contributions Formey presented in the “speculative philosophy” class of the Academy. In this paper, I analyse two articles Formey published in 1747 on the Mémoires de l’Académie de Berlin, namely the Preuves de l’existence (...) de Dieu, ramenées aux notions communes and the Examen de la preuve qu’on tire des fins de la nature, pour établir l’existence de Dieu. In these texts, Formey presents some of Wolff’s methodological and metaphysical ideas, in an implicit dialogue with other members of the Academy – in particular, with the president Pierre-Louis Moreau de Maupertuis – who were also interested in metaphysics and the philosophical method. Formey reworks the Wolffian arguments as to make them more accessible, in order to promote an open confrontation over core philosophical questions. Far from adopting a controversial tone, Formey’s attitude is rather conciliatory: any disagreement, as he thinks, can be easily settled once the true method for philosophizing is made available to everybody.

The Enlightenment critique of the esprit de système and its tendency towards eclecticism have often been interpreted as symptoms of speculative shallowness. The article analyses the origins of this prejudice, with special reference to the early French Enlightenment (1700-1750). It then attempts to counter such a preconception by providing a relevant counterexample. The case study presented is that of Pierre-Louis Moreau de Maupertuis, usually considered a typical instance of the anti-systematic proto-positivist philosophe. In discussing his philosophy, epistemological and (...) cosmological issues in particular are emphasized, showing how Maupertuis’ thoroughly empiricist theory of knowledge led him to apply mathematics to all domains of human knowledge in order to reduce their uncertainty. It is concluded that Maupertuis is the author of a rich and interesting work, which brings some novelty to the philosophical scene of his own times, if not to the whole history of modern philosophy.

Without doubt, the principle of least action is a fundamental principle in classical mechanics. Contemporary physicists, however, consider the PLA as a purely mathematical principle – even an axiom which they cannot completely justify. Such an account stands in sharp contrast with the historical meaning of the PLA. When the principle was introduced in the 1740s, by Pierre-Louis Moreau de Maupertuis, its meaning was much more versatile. For Maupertuis the principle of least action signified that nature is thrifty (...) or economical in all its actions, i.e., that nature avoids to do anything unnecessary. Maupertuis understood the principle in teleological terms and even considered the principle as an expression of God’s wisdom. It has been correctly pointed out by historians that Maupertuis in his later years moved towards a more speculative and metaphysical approach, whereas his contemporary Euler and later Lagrange, wanted to avoid such theological and metaphysical implications and frame the PLA in purely mathematical terms. Such readings, however, have had the unintended side-effect that they lose out of sight the question how the mathematical and metaphysical aspect of the principle of least action fit together within Maupertuis’ own work. Investigating if and how the mathematical and metaphysical aspects of the PLA are compatible within Maupertuis’ thought will be the main goal of this paper. (shrink)

Pierre Louis Moreau de Maupertuis’ famous and influential Discours sur les différentes figures des astres, which represented the first public defense of attractionism in the Cartesian stronghold of the Paris Academy, sometimes suggests a metaphysically agnostic defense of gravity as simply a regularity. However, Maupertuis’ considered account in the essay, I argue, is much more subtle. I analyze Maupertuis’ position, showing how it is generated by an extended consideration of the possibility of attraction as an inherent property and (...) fuelled by an understanding of Lockean skepticism about knowledge of real essences that is more nuanced perhaps even than Locke’s own.

At the very beginning of L’Homme-Machine, La Mettrie claims that Leibnizians with their monads have “rather spiritualized matter than materialized the soul”; a few years later Pierre-Louis Moreau de Maupertuis, President of the Berlin Academy of Sciences and natural philosopher with a strong interest in the modes of transmission of ‘genetic’ information, conceived of living minima which he termed molecules, “endowed with desire, memory and intelligence,” in his Système de la nature ou Essai sur les corps organisés. This (...) text first appeared in Latin in 1751 under the title Dissertatio inauguralis metaphysica de universali naturae systemate, with the pseudonym Dr Baumann; it was translated by Maupertuis in 1754 as Essai sur la formation des corps organisés and was later included in his 1756 Œuvres under the title Système de la nature. Now, it is clear that Maupertuis was a kind of Leibnizian; and that his molecule possessed higher-level, ‘mental’ properties. In that sense he falls under the first category described by La Mettrie. But he was also involved in a debate on this issue with Diderot, who put forth a sustained critique of Maupertuis’ theory of the molecule in the additions to his 1753 Pensées sur l’interprétation de la nature. Where Maupertuis attributes higher-level properties to his living minima, Diderot argues that these properties are ‘organizational’, i.e., they can only be properties of the whole. At issue here is the degree of commitment to a form of materialism. (shrink)

The present paper aims to examine the biological works of Pierre-Louis Moreau de Maupertuis (1698–1759), a prominent French scientist and philosopher, on the problems of animal reproduction and heredity. His scientific career exemplifies how, in mid-eighteenth-century Europe, various scientific disciplines were intertwined with literature, art, and philosophy. In one of his major publications dealing with these issues, “Venus physique” (1745), from one role to another time and again, combining theory, observation, everyday experience, and literary narrative. His objections to (...) preformationism unfold in a stylized literary context that itself references the more personal context of salon conversation and flirtation. Maupertuis’s epigenetic conception of reproduction (with its origins in Antiquity) drew on a wide range of arguments from a variety of sources: anatomy and monster studies, observations of racial differences and family resemblance, analysis of the breeding experience of animal breeders, microscopic observations, and chemical insights. The French scientist presented the dynamics of processes in living nature in terms of naturalized desire and aversion, which function as guiding inclinations inherent in the smallest units of organic matter. In “Venus physique”, Maupertuis, in presenting his biological views, played on the appeal in certain Parisian circles of socially acceptable epathetics associated with philosophical texts, eroticism, unorthodox religious beliefs, and illicit sexual liaisons.

In 1751, LEONHARD EULER established “harmony” between two principles that had been stated by PIERRE-LOUIS-MOREAU DE MAUPERTUIS a few years earlier. These principles are intended to be the foundations of Mechanics; they are the principle of rest and the principle of least action.My claim is that the way in which “harmony” is achieved sets the foundations of so called Analytical Mechanics: it discloses the physical bases of the general ideas, concepts, and motivations of the formalism. My paper intends (...) to show what those physical bases are, and how a picture of the formalism issues from them. This picture is shown to be recast in JOSEPH-LOUIS LAGRANGES justification of the formalism, which strengthens my claim. (shrink)

This work contrasts the formalist approach to defining explanation in science, exemplified in the Deductive-Nomenological Model of Carl G. Hempel, with the contextualist approach of Thomas Kuhn. It is argued that both of these attempts to define the explanatory processes of science are inadequate. A connection is made between the view of rationality upon which each view is based and the way that it defines explanation. It is argued that a process of thought, which scientific explanation represents, is considered rational (...) by these thinkers only if it meets the criteria of constraint under a rule, distance from subjective considerations and instrumental connection of method and goal. Given this strong definition of rationality, explanation is defined by both Kuhn and Hempel as thought within the constraint of a theory or a theoretical paradigm. Under this construal, explanation is separated as a process from theory invention which both thinkers hold to involve primarily non-cognitive criteria of choice. It is argued in this work that such a view contradicts the actual practice of science where theory invention seems to be primarily a process of rational explaining. ;A detailed historical case of an attempt to explain organic morphogenesis is given. It centers on the theory of generation of Pierre Louis Moreau de Maupertuis, an 18th Century scientific thinker. This case is meant to illustrate the kinds of cognitive interest and strategies of invention that go into dealing with an explanatory problem in science. ;Finally some general programmatic conclusions are made relating the foregoing arguments and the case, to the need to explore the nature of scientific explanation in the domain of theory invention where the reasoning processes seem to involve analogical reasoning and critical metaphysical thought.

Ce recueil d'articles, publié pour la première fois en 1965 aux Editions François Maspero, a connu un succès exceptionnel pour un ouvrage théorique : quinze tirages (soit 45 000 exemplaires) et de très nombreuses traductions. Comme le notait Elisabeth Badinter dans Combat du 25 avril 1974 : "Les étudiants et les intellectuels marxistes découvrirent Althusser et à travers lui, sinon un nouveau Marx, du moins une nouvelle façon de le lire. Depuis la Critique de la raison dialectique de Sartre, Althusser (...) est le seul philosophe à proposer une interprétation vraiment originale des œuvres de Marx. " Depuis les années 1960, les études marxistes n'ont pu ignorer cette approche qui établissait une "coupure épistémologique" dans l'œuvre marxienne, séparant les textes idéologiques du jeune Marx de ceux plus scientifiques du Marx de la maturité. Elle offrait aussi une autre évaluation de l'apport de Hegel à Marx et n'hésitait pas à s'inspirer des réflexions philosophiques de Mao Zedong pour nourrir sa propre philosophie. Rares sont les livres ayant suscité autant de passions théoriques et provoqué autant de débats. "Comment expliquer une telle influence? D'abord, évidemment, par la nouveauté qui caractérise, dans les années 1960-1965, sa lecture de Marx. Lecture "symptomale ", au sens freudien du terme, c'est-à-dire attentive au non-dit tout autant qu'au discours explicite... Il s'agit d'en finir avec la version humaniste, bavarde et idéologique du marxisme vulgaire et de donner le jour à une véritable pratique révolutionnaire, fondée sur un savoir rigoureux. " Le Monde.

Nous vivons présentement un nouveau moment historique du capita­lisme avec la montée en puissance de sa financiarisation , avec la chute du mur de Berlin et l’implosion du communisme , avec le retour des religions à l’avant-scène de l’espace public mondial , avec l’échec du développement dans les pays du Sud simultanément à la montée dans les pays du Nord de la précarité du travail, avec l’urgence écologique, notamment avec le réchauffement climatique, menace de toutes les menaces sur ce plan. (...) Ces tendances fortes ont ébranlé les certitudes de la deuxième partie du xxe siècle. Mais, partout dans le monde, nous avons éga­lement assisté à l’émergence ou au renouvellement de mouvements sociaux qui exigent plus de démocratie, de contrôle des communautés sur leur développe­ment, de justice sociale et de transition écologique de leur économie. Un véritable changement de paradigme, de politique et de stratégie prend peut-être place progressivement. Espoir réinventé ? De quoi s’agit-il plus précisément ? (shrink)

Signifiance du monde propose une "harmonisation intégrale" entre la linguistique saussuro-guillaumienne des langues naturelles et la pensée phénoménologique heideggérienne de la vérité de l'être en tant qu'alètheia, dans son sens grec de "ce qui sort de la latence" et que Jean-Louis Tristani nomme illatence. En d'autres termes, cet essai donne accès à une compréhension des "relations grammaticales évidentes qui articulent l'être, dans sa vérité, et la pensée, telles qu'elles sont a priori données dans le système linguistique de n'importe quelle (...) langue naturelle". Cette mise au jour de la co-originarité de la langue et de la pensée corrobore la formule du linguiste français Antoine Meillet, maintes fois citée par Gustave Guillaume, selon laquelle, en ce lieu intelligible de la langue "tout se tient et a un plan d'une pleine rigueur". Une rigueur qui intègre le système morpho-lexical d'une langue, en tant qu'intégrale des conditions d'effection du discours, avec les conditions existentiales de possibilité du Dasein en tant qu'être-au-monde. D'où Signifiance du monde, ce titre qui annonce la composante linguistique de notre présence au monde."--Page 4 of cover. (shrink)
