Cet article vise à souligner la centrante de Laf.308, Br.793 au sein des Pensées, tout en déterminant sa portée anti-cartésienne. Une confrontation avec d'autres fragments connexes permet de préciser ce que Pascal met sous le deuxième ordre : une science relayée par la pensée, non la métaphysique cartésienne. Il devient alors possible de discuter l'interprétation de Jean-Luc Marion et de montrer que, loin d'opérer une simple destitution de la métaphysique cartésienne au nom de la charité chrétienne, Laf.308, Br.793 résume bien (...) l'antagonisme de deux systèmes philosophiques. The object of this article is to point out the central place of Laf.308-Br.793 within the Pensées and to determine at the same time its anti-cartesian implications. By confronting it with connected fragments, we are allowed to state what exactly Pascal does include under the second order, that is, not the cartesian metaphysics, but a science whose relay is the thought. So it becomes possible to discuss Jean-Luc Marion's interpretation by showing that, far from simply producing a destitution of the cartesian metaphysics in the name of Christian charity, Laf.308-Br.793 concentrates well the antagonism between two philosophical systems.

Malebranche holds that sensory experience represents the world from the body’s point of view. I argue that Malebranche gives a systematic analysis of this bodily perspective in terms of the claim that the five familiar external senses and bodily awareness represent nothing but relations to the body.

We look at some interesting and important episodes in the life of early modern Epicureanism, focusing on natural philosophy. We begin with two early moderns who had a great deal to say about ancient Epicureanism: Pierre Gassendi and Ralph Cudworth. Looking at how Gassendi and Cudworth conceived of Epicureanism gives us a sense of what the early moderns considered important in the ancient tradition. It also points us towards three main themes of early modern Epicureanism in natural philosophy, which we (...) then discuss at greater length: atomism, materialism about the mind or soul, and the denial of providence, which was often accompanied by deflationary explanations of religious belief.

In this work I intend to explore the textual and conceptual roots of the moral view in the Early Modern Rationalism of Cartesian spectrum as detected by Elisabeth of Bohemia. To this intent, I will drive my analysis, first, to the remark Descartes adds to his own provisional morality of the Discourse in the Letter of August 4th, 1645 to Elisabeth. Second, I will approach the two aspects of her reply to Descartes, both in her Letter of September 13th 1645, (...) which I call a) the contextual aspect – with which she excludes the hypotheses of an infinite science at the service of assessing the good and b) the self-related aspect, with which the philosopher of Bohemia address the moral objectiveness as an intrinsic practical value, obtained by the passions that may lead to reasonable actions. The upshot is a practical and affective moral view, in which the normative trait of some passions of the soul can be taken as the explanation of an intentional infrastructure of the mind, without, however, a theory of ideas as such playing an explicit role. Instead of a representational endeavor, Elisabeth of Bohemia claims a kind of self-awareness from the discovery of a passionate function as an expression of the adequate measure between happiness and morality of actions. That kind of awareness, I shall demonstrate, is what objectiveness consists in. (shrink)

This paper is about two things that cross paths. One is the many senses of the category ‘Newtonian,’ and their uses for exegesis. The other is the physics that Emilie du Châtelet grounded philosophically around 1740 in her book, Institutions de physique.

I begin by outlining Du Châtelet’s ontology of mathematical objects: she is an idealist, and mathematical objects are fictions dependent on acts of abstraction. Next, I consider how this idealism can be reconciled with her endorsement of necessary truths in mathematics, which are grounded in essences that we do not create. Finally, I discuss how mathematics and physics relate within Du Châtelet’s idealism. Because the primary objects of physics are partly grounded in the same kinds of acts as yield mathematical (...) objects, she thinks we are sometimes licensed in drawing conclusions about physical things from mathematical premises.

This is an English translation of Emilie Du Châtelet's "Sur la liberté." This 18th century text discusses freedom of the will, determinism, and divine foreknowledge. Translated from French by Julia Jorati, with the help of Julie Roy.

This article reveals three aspects of victimhood in Bataille’s reading of Sade (of the other, of the self, and Sade’s language) and relates them to some of Bataille’s metaphysical and political notions: the impossible, the general and the restricted economy, sovereignty, and transgression. Doing so shows a progressive simplification of possibilities for transgression from the pre-Christian world to that of popular sovereignty, i.e., the sovereignty of the crowd, the latter leaving open one avenue for transgression: Sadean victimhood. The article then (...) applies these aspects to the pamphlet in Sade’s Philosophy in the Boudoir, “Frenchmen, Some More Effort If You Wish to Become Republicans,” in relation to a contemporaneous document of popular sovereignty, the preamble to the Constitution of the Year III, titled “Declaration of the Rights and Duties of Man and Citizen.” Attending to the aspects of Sadean victimhood in “Effort” shows that its system’s very impossibility makes it the Declaration’s logical completion. Finally, that impossibility is revealed as the sovereignty of the masses, distinct from that of the crowd. (shrink)

Em maio de 1643, Elisabeth da Bohemia endereçou uma questão a Descartes que inaugurou uma Correspondência de seis anos, até a morte do filósofo. Ele dedica à Princesa o seu trabalho de maturidade metafísica (Princípios de Filosofia Primeira, 1644) e redige Paixões da Alma (1649) como um dos resultados do diálogo com a filósofa. O silenciamento dos últimos cem anos de historiografia sobre o legado de Elisabeth da Bohemia nesta troca epistolar causou distorções e, em alguns casos, lastreou o viés (...) como regra e como a história. Uma das consequências dessa distorção está na leitura de que a questão da filósofa consistiria em uma crítica ao dualismo substancial. Neste estudo busco oferecer uma interpretação da natureza da primeira questão, com o intuito de esclarecer o pensamento da filósofa e o seu papel no diálogo, de uma maneira compreensiva, sem subscrever o paradigma literário do solilóquio cartesiano, e seu viés na literatura filosófica.

There is a tension in Emilie Du Châtelet’s thought on mathematics. The objects of mathematics are ideal or fictional entities; nevertheless, mathematics is presented as indispensable for an account of the physical world. After outlining Du Châtelet’s position, and showing how she departs from Christian Wolff’s pessimism about Newtonian mathematical physics, I show that the tension in her position is only apparent. Du Châtelet has a worked-out defense of the explanatory and epistemic need for mathematical objects, consistent with their metaphysical (...) nonfundamentality. I conclude by sketching how Du Châtelet’s conception of mathematical indispensability differs interestingly from many contemporary approaches. (shrink)

The querelle des femmes was an intellectual debate over the status of women that occurred in the early modern period, between the 1400s and 1700s. A common argument for the superiority of men and inferiority of women that appeared during the debate is that women are less physically strong than men, and are therefore inferior. In response, two distinct argumentative strategies were developed by defenders of women. First, some argued that men and women did not in fact differ in physical (...) strength. A second strategy was to deny that physical strength is relevant to the question of superiority. In this case, one would argue that a difference in strength is not normatively relevant to evaluations of worth. I argue that this second strategy was the more effective response to the argument that women were inferior because of their alleged physical weakness compared to men. (shrink)

Malebranche holds that visual experience represents the size of objects relative to the perceiver's body and does not represent objects as having intrinsic or nonrelational spatial magnitudes. I argue that Malebranche's case for this body-relative thesis is more sophisticated than other commentators—most notably, Atherton and Simmons —have presented it. Malebranche's central argument relies on the possibility of perceptual variation with respect to size. He uses two thought experiments to show that perceivers of different sizes—namely, miniature people, giants, and typical human (...) beings—can experience the very same objects as having radically different sizes. Malebranche argues that there is no principled reason to privilege one of these ways of experiencing size over the others and, more specifically, that all three kinds of perceivers experience size veridically. From the possibility of this kind of veridical perceptual variation, Malebranche infers that visual experience represents only body-relative size. (shrink)

This essay responds to scholarly neglect which Diderot’s “Éloge de Richardson” has met for being regarded as too colourful (“trop coloré”). Focus on the emotive aspect of the “Éloge” is, here, shown to reveal commentary on philosophy itself; Samuel Richardson’s work thus occasions a fresh take on philosophical discourse. Diderot’s “Éloge” proves to be a new twist in literary criticism as well as an important contribution to philosophy proper.

- Emilie du Châtelet offers an interesting and unusual account of the origin of our representation of extension. - She is an idealist about the essence extension, bodies and space, regarding them as mental constructs. - Du Châtelet's account requires a brute fact about the mind, in apparent tension with the Principle of Sufficient Reason.

In this study, I intend to show how and why, in the Port-Royal Logic, a singular term can reveal the nature of the logical judgment in the handbook. As I argue, the treatment given to one of thee singular terms, namely, the defined descriptions, in the terminology introduced by Russell, leads to an opening to langage that sounds unexpected and unjustified. Considering the privilege of thinking over langage and also that judgment is the mental act that defines logic, however, we (...) may understand how the authors regard langage, in relation to the epistemic constituents, namely, the mental acts within the terms. In doing so we are compelled to recognize the implications of this step towards pragmatism in fixing the meaning of defined descriptions to the nature of judgment in the handbook. This opening to langage reveals the conception of judgment as a twofold mental act: a formal and a practical (moral and theological) one. (shrink)

The Cartesian view that animals are automata sparked a major controversy in early modern European philosophy. This paper studies an early contribution to this controversy. I provide an interpretation of an influential objection to Cartesian animal automatism raised by Ignace-Gaston Pardies (1636–1673). Pardies objects that the Cartesian arguments show only that animals lack ‘intellectual perception’ but do not show that animals lack ‘sensible perception.’ According to Pardies, the difference between these two types of perception is that the former is reflexive (...) such that we both perceive an object and the perception itself, whereas sensible perception lacks this reflexivity. This notion of sensible perception was criticized by the Cartesian Antoine Dilly for violating the doctrine that all thought is conscious. However, I argue that sensible perceptions are not unconscious for Pardies. Rather, they are conscious perceptions that are unaccompanied by a kind of reflexive perception that is constitutive of attention. Moreover, I argue that when understood in this way Pardies raises a compelling objection to Cartesian animal automatists. (shrink)

A central project of Enlightenment thought is to ground claims to natural freedom and equality. This project is the foundation of Suchon’s view of freedom. But it is not the whole story. For, Suchon’s focus is not just natural freedom, but also the necessary and sufficient conditions for oppressed members of society, women, to avail themselves of this freedom. In this paper I, first, treat Suchon’s normative argument for women’s right to develop their rational minds. In Section 2, I consider (...) Suchon’s three necessary and sufficient conditions for freedom, and the manners in which women are blocked from meeting them. The normative argument together with the obstacles to women meeting the conditions for freedom raises the question of how to get women into a position where they can enjoy the freedom to which they are entitled. In Section 3, I outline Suchon’s answer: women must live a life without attachment. I argue this answer situates Suchon both chronologically and theoretically between the Béguines, a medieval women’s spiritual movement, and 20th century feminist separatism. I conclude that Suchon’s view of freedom is radical, both for its time and ours, and deserves greater attention from historians of philosophy and of feminist thought. (shrink)

ABSTRACTBernard Lamy is frequently included among the Cartesian Empiricists of the second half of the seventeenth century. He has also been described as an Augustinian who dabbled in Cartesianism. While acknowledging that there are both empiricist and Augustinian elements in his thought, I argue that it ought not be forgotten that there are central components of his philosophy that are both anti-empiricist and in opposition to Augustine. My aim in this paper, though, is not critical; I hope to show that (...) Lamy provides us with one more example of the diversity present among the various thinkers labelled as ‘Cartesian’. (shrink)

L’histoire de la pensée sémiotique se caractérise par une oscillation entre définition large et définition étroite de son objet. Au Moyen Âge, la définition augustinienne du signe est jugée trop étroite, car elle ne concerne que le signe sensible. De nouvelles définitions tentent alors de faire des concepts des signes qui renvoient aux choses. L’Âge moderne, au contraire, affirme une volonté de rétrécissement à l’égard de la notion de signe. Cet article montrera les caractéristiques d’une telle réflexion sémiotique à travers (...) deux auteurs représentatifs d’un premier empirisme moderne : Pierre Gassendi et Thomas Hobbes. Le retour à une sémiotique étroite s’effectue par la référence aux traditions stoïcienne, sceptique et épicurienne, ainsi qu’à un Aristote renouvelé, et par une prédilection affichée pour la valeur indiciaire du signe par rapport à sa valeur sémantique. Ceci veut dire que les empiristes vont insister avant tout sur la fonction remémorative du signe et sur sa valeur de probabilité. L’indice en tant que trace sera ainsi privilégié par rapport au signe communicationnel, et il s’agira d’en défendre la validité en tant qu’il s’inscrit dans une échelle de certitude, au sommet de laquelle se situe la preuve.

The 17th century author François Poulain de la Barre was an important contributor to a pivotal moment in the history of feminist thought. Poulain borrows from many of Descartes’s doctrines, including his dualism, distrust of epistemic authority, accounts of imagination, and passion, and at least some aspects of his doxastic voluntarism; here I examine how he uses a Cartesian notion of prejudice for an anti-essentializing philosophy of women’s education and the formation of the tastes, talents and interests of individuals. ‘Prejudice’ (...) remains Descartes’s notion of an entrenched, yet self-imposed doxastic commitment, but also takes on the sense of social-political group bias, founded on custom, transmitted through education, serving interests, and forming social expectations. Poulain also expands on the Cartesian notion and themes by emphasizing widespread, yet unjustified social opinions in favor of the status quo in both epistemic practices and epistemic authorities, while considering how biased beliefs about sexual difference and gender identity can be internalized even by those who suffer most from them. At the same time, he shows how powerful Cartesian concepts can be for feminist methodology, even though they might also be put to problematic uses (as Malebranche did). (shrink)

La conception malebranchiste de la liberté est originale. Malebranche ne croit pas en une liberté d’indifférence absolue, c'est-à-dire en une capacité d’opérer un choix indépendamment de toute motivation. Il ne croit pas non plus que nous puissions indifféremment choisir entre deux motivations de force inégale : au moment où on se détermine, le bien le plus grand (du moins selon l’apparence) l’emporte. La liberté réside seulement dans le fait que l’on n’est pas obligé de se déterminer : nous pouvons toujours (...) suspendre notre consentement. Cette conception est exposée à des objections que Pierre Bayle a formulées et qui tentent de la mettre en contradiction avec d’autres thèses de Malebranche : son occasionalisme, sa théorie de la création continuée, l’obscurité de l’âme à elle-même, sa théologie des voies de l’action divine. Nous discuterons ces objections et verrons si Malebranche est en mesure de leur résister. (shrink)

much early modern metaphysics grew with an eye to the new science of its time, but few figures took it as seriously as Emilie du Châtelet. Happily, her oeuvre is now attracting close, renewed attention, and so the time is ripe for looking into her metaphysical foundation for empirical theory. Accordingly, I move here to do just that. I establish two conclusions. First, du Châtelet's basic metaphysics is a robust realism. Idealist strands, while they exist, are confined to non-basic regimes. (...) Second, her substance realism seems internally coherent, so her foundational project appears successful.I have two aims in this paper. Historically, I show that du Châtelet's main source of inspiration was Christian... (shrink)

Baron d’Holbach was a critic of established religion, or a philosophe, in late 18 th -century France. His work is often perceived as less inventive than the work of other materialist philosophes, such as Helvétius and Diderot. However, I claim that d’Holbach makes an original, unjustly overlooked move in the criticism of religious moral teaching. According to the materialist philosophes, this teaching claims that true happiness is only possible in the afterlife. As an alternative, Helvétius and Diderot offer theories according (...) to which the experience of pleasure constitutes happiness, the end of all human desire. In contemporary terms, these theories would represent psychological hedonism. But, as Diderot himself admits, they have a problem in accounting for why people seem to naturally regard some pleasures as preferable to others. I argue that in response to this challenge, instead of accepting the psychological hedonism of his fellow materialists, d’Holbach shows how one can abstain from reducing happiness to pleasure and yet remain a materialist.

Foreword from the Guest Editor to the special issue of Diametros – “Enlightenment and Secularism.”.

Descartes’s very brief explanations of human responsibility for sin and divine innocence of sin include references to the idea that evil is a privation rather than a real thing. It is not obvious, though, that privation fits naturally in Descartes’s reductionistic metaphysics, nor is it clear precisely what role his privation doctrine plays in his theodicy. These issues are made clear by contrasting Descartes’s use of privations with that of Suarez, particularly in light of reoccurring objections to privation theory. These (...) objections have no weight against Suarez’s use of privations, but Descartes’s mentions of privation are so few that it is not clear how his account avoids their consequences. Descartes’s brevity seems to have motivated some of his followers to develop creative accounts of the way in which privation fits in a Cartesian system. Pierre-Sylvain Régis accomplishes this task by reintroducing material causation. Régis holds that moral evil has no efficient cause since an efficient cause can only produce something real. Because he holds that moral evil can have a material cause, he is able to affirm that the soul is morally responsible for sin. In Régis’s case, accommodating this theological issue meant reincorporating Aristotelian resources into his Cartesian system. (shrink)

In the mid-seventeenth century a movement of self-styled experimental philosophers emerged in Britain. Originating in the discipline of natural philosophy amongst Fellows of the fledgling Royal Society of London, it soon spread to medicine and by the eighteenth century had impacted moral and political philosophy and even aesthetics. Early modern experimental philosophers gave epistemic priority to observation and experiment over theorising and speculation. They decried the use of hypotheses and system-building without recourse to experiment and, in some quarters, developed a (...) philosophy of experiment. The movement spread to the Netherlands and France in the early eighteenth century and later impacted Germany. Its important role in early modern philosophy was subsequently eclipsed by the widespread adoption of the Kantian historiography of modern philosophy, which emphasised the distinction between rationalism and empiricism and had no place for the historical phenomenon of early modern experimental philosophy. The re-emergence of interest in early modern experimental philosophy roughly coincided with the development of contemporary x-phi and there are some important similarities between the two. (shrink)

The title of Roger Ariew’s new book parallels that of his earlier collection of essays, Descartes and the Last Scholastics, published in 1999 and widely regarded as a signal contribution to the study of Descartes’s relationship to his intellectual predecessors. Some of the themes of that work are reflected in the new book as well. In both, Ariew seeks to overthrow the myth of Descartes as staunch opponent of Scholasticism by revealing his affinities to strands of Scholastic thought. Indeed, given (...) the title, it may be surprising that much of Descartes and the First Cartesians focuses on Descartes’s relationship to Scholastic philosophy. The reason is that Ariew’s aim is to show how Descartes’s followers designed.. (shrink)

Atheism was the most foundational challenge to early-modern French certainties. Theologians and philosophers labelled such atheism as absurd, confident that neither the fact nor behaviour of nature was explicable without reference to God. The alternative was a categorical naturalism, whose most extreme form was Epicureanism. The dynamics of the Christian learned world, however, which this book explains, allowed the wide dissemination of the Epicurean argument. By the end of the seventeenth century, atheism achieved real voice and life. This book examines (...) the Epicurean inheritance and explains what constituted actual atheistic thinking in early-modern France, distinguishing such categorical unbelief from other challenges to orthodox beliefs. Without understanding the actual context and convergence of the inheritance, scholarship, protocols, and polemical modes of orthodox culture, the early-modern generation and dissemination of atheism are inexplicable. This book brings to life both early-modern French Christian learned culture and the atheists who emerged from its intellectual vitality. (shrink)

Essay review of Roger Ariew, Descartes and the first Cartesians. Oxford: Oxford University Press 2014. xix + 236 S.

Political writings of eighteenth-century France have been so far mostly overlooked as a source of republican thought. Philosophers such as Condorcet actively promoted the ideal of republicanism in ways that can shed light on current debates. In this paper, I look at one particular source: Le Republicain, published in the summer 1791, focusing on previously unattributed articles by Condorcet’s wife and collaborator, Sophie de Grouchy. Grouchy, a philosopher in her own right, is beginning to be known for her Letters on (...) Sympathy, a response to Adam Smith’s Theory of Moral Sentiment, which she published at the same time as her translation of that text into French. I argue, further, that in the texts, which I attribute to Grouchy, we can find the early development of a commercial republican theory, a belief, which is reflected in her discussion of the ‘cost’ of tyranny.

This article tries to show how, in his philosophy, Diderot assumes the character of a rhetorician: each idea is inseparable fro m the imagination that has created it, constituting a thought that is based on analogical and metaphorical references. In this perspective, my article considers the Encyclopédie as the most specific product of the philosopher-rhetorician’s thought: here the human knowledge organizes itself in a totality unfinished and ever-changing, where the articles are placed in a network of multiple references, never unambiguous (...) and transparent. The result is a work in which each statement has an ambiguous and never final status: with this background, irony now appears as the constitutive factor of a human knowledge that always redefines its centres and its suburbs, creating unstable symmetries and balances.

Nel mio articolo mi propongo di mostrare come nell'opera filosofica di D. Diderot la ridefinizione della materia - attiva e capace di dar origine continuamente a nuove forme - passi per la riconsiderazione dei suoi rapporti con l'immaginazione e le capacità rappresentative umane. A tal fine, prenderò in analisi uno specifico passo de Le rêve de d'Alembert, nel quale Diderot metaforizza la capacità della materia di divenire attiva a partire dalla riduzione in polvere di una statua di Falconet. Si dimostrerà (...) che l'opera dello scultore, distrutta e consegnata a nuova vita dal philosophe, non è dedicata a un soggetto qualsiasi: essa rappresenta infatti Pigmalione ai piedi della statua che si anima. La materia che si anima è allora in Diderot quella che già rappresenta la materia stessa nell'atto di animarsi. Facendo del mito ovidiano di Pigmalione il baricentro della riflessione settecentesca sulla materia e sull'immagine, nella loro reciproca interazione, il mio articolo cercherà pertanto di ridefinirne i rapporti reciproci e, attraverso una fisiologia che si origina da una tattilità diffusa, traccerà i contorni di un materialismo in cui materia e rappresentazione, cose e immagini convivono all'altezza di un'immaginazione che continuamente dà forma al reale e alle parole che lo descrivono e lo riscrivono.

Questo volume raccoglie alcune riflessioni sul ruolo della finzione nella letteratura e nella filosofia del Settecento e del Novecento. La premessa del lavoro è di non negare aprioristicamente il valore della multiforme nozione di finzione per il pensiero rigoroso. In tal modo, in un percorso che si dipana da Vico a Queneau passando per Diderot, Rousseau, Gide e Valéry, gli autori indagano diverse esperienze di interazione tra riflessione e finzione, mettendo in luce l’arricchimento per il pensiero che di volta in (...) volta ne risulta. Il lavoro è frutto del laboratorio di filosofia della letteratura del gruppo Zetesis ed è stato realizzato grazie al contributo del Consiglio degli Studenti dell’Università di Pisa. (shrink)

The impression we are often given by historians of philosophy is that the readiness of medieval philosophers to appeal to authorities, such as The Bible, the Church, and Aristotle, was not shared by many early modern philosophers, for whom there was a marked preference to look for illumination via experience, the exercise of reason, or a combination of the two. Although this may be accurate, broadly speaking, it is notable that, in spite of the waning enthusiasm for deferring to traditional (...) authorities, appeals to scripture remained commonplace in the work of early modern philosophers. In order to understand the philosophers of the early modern period, the philosophies they developed, and the debates they fought, we need to understand how they used scripture. This paper is intended to contribute to this desideratum by examining how scripture was used by those who engaged in a particular debate within natural philosophy, the so-called beast-machine controversy of the 17th and 18th centuries.

A central controversy in the reception of Leibniz’s philosophy, not only during his lifetime, but also in the immediately posthumous period and more recently, concerns the role that substantial forms play in Leibniz’s ontology. Interpreters like Garber argue that the Leibnizian defense of the quasi-Scholastic substantial forms in the 1680’s-1690’s demonstrate an ontology of corporeal substance irreducible to an idealist ontology. On the other hand interpreters like Adams argue that corporeal substances reduce to a fully idealist ontology and that this (...) period in Leibniz’s work only demonstrate a modification of idealism. In this paper I argue that without clarifying the ambiguous status of what constitutes “ontology” for Leibniz, the stakes of this longstanding debate are unclear and the anti-idealist position appears to be a self-defeating one. By turning to a thorough reading of Leibniz’s transition from the middle to the late years and noting key turns in its historical reception, I argue that the anti-phenomenalist position becomes meaningful in light of an idealist ontology rather than in spite of it. My aim is not to defend either idealism or anti-idealism but rather to reconfi gure the nature of the controversy concerning substantial forms by outlining the limits of current debates over Leibniz’s ontology.

The concept of self has preeminently been asserted (in its many versions) as a core component of anti-reductionist, antinaturalistic philosophical positions, from Descartes to Husserl and beyond, with the exception of some hybrid or intermediate positions which declare rather glibly that, since we are biological entities which fully belong to the natural world, and we are conscious of ourselves as 'selves', therefore the self belongs to the natural world (this is characteristic e.g. of embodied phenomenology and enactivism). Nevertheless, from Cudworth (...) and More’s attacks on materialism all the way through twentieth-century argument against naturalism, the gulf between selfhood and the world of Nature appears unbridgeable. In contrast, my goal in this paper is to show that early modern materialism could yield a theory of the self according to which (1) the self belongs to the world of external relations (Spinoza), such that no one fact, including supposedly private facts, is only accessible to a single person; (2) the self can be reconstructed as a sense of “organic unity” which could be a condition for biological individuality (a central text here is Diderot’s 1769 Rêve de D’Alembert); yet this should not lead us to espouse a Romantic concept of organism as foundational or even ineffable subjectivity (a dimension present in Leibniz and made explicit in German idealism); (3) what we call 'self' might simply be a dynamic process of interpretive activity undertaken by the brain. This materialist theory of the self should not neglect the nature of experience, but it should also not have to take at face value the recurring invocations of a better, deeper “first-person perspective” or “first-person science.”.

Maimon’s theory of the differential has proved to be a rather enigmatic aspect of his philosophy. By drawing upon mathematical developments that had occurred earlier in the century and that, by virtue of the arguments presented in the Essay and comments elsewhere in his writing, I suggest Maimon would have been aware of, what I propose to offer in this paper is a study of the differential and the role that it plays in the Essay on Transcendental Philosophy (1790). In (...) order to do so, this paper focuses upon Maimon’s criticism of the role played by mathematics in Kant’s philosophy, to which Maimon offers a Leibnizian solution based on the infinitesimal calculus. The main difficulties that Maimon has with Kant’s system, the second of which will be the focus of this paper, include the presumption of the existence of synthetic a priori judgments, i.e. the question quid facti, and the question of whether the fact of our use of a priori concepts in experience is justified, i.e. the question quid juris. Maimon deploys mathematics, specifically arithmetic, against Kant to show how it is possible to understand objects as having been constituted by the very relations between them, and he proposes an alternative solution to the question quid juris, which relies on the concept of the differential. However, despite these arguments, Maimon remains sceptical with respect to the question quid facti. (shrink)

In Diderot’s philosophy, the nature of the eighteenth-century, Isis veiled, is constituted of the same substance as the metaphor, the analogy and the hieroglyph. To show that, this article takes into consideration the naturalistic inquiry on Trembley’s Hydra. This animal, which is at the heart of the philosophical interest of the period, seems to shape itself starting from the mythological imagination, but at the same time it becomes the model that, for Diderot, defines the faculty of thinking and its features. (...) The reversibility between word and image, nature and culture, representation and the represented thing provides the observation point on a philosophy – Diderot’s philosophy – that develops itself along with the human physiology and imagination, its own faculty.

Newton’s impact on Enlightenment natural philosophy has been studied at great length, in its experimental, methodological and ideological ramifications. One aspect that has received fairly little attention is the role Newtonian “analogies” played in the formulation of new conceptual schemes in physiology, medicine, and life science as a whole. So-called ‘medical Newtonians’ like Pitcairne and Keill have been studied; but they were engaged in a more literal project of directly transposing, or seeking to transpose, Newtonian laws into quantitative models of (...) the body. I am interested here in something different: neither the metaphysical reading of Newton, nor direct empirical transpositions, but rather, a more heuristic, empiricist construction of Newtonian analogies. Figures such as Haller, Barthez, and Blumenbach constructed analogies between the method of celestial mechanics and the method of physiology. In celestial mechanics, they held, an unknown entity such as gravity is posited and used to mathematically link sets of determinate physical phenomena (e.g., the phases of the moon and tides). This process allows one to remain agnostic about the ontological status of the unknown entity, as long as the two linked sets of phenomena are represented adequately. Haller et. al. held that the Newtonian physician and physiologist can similarly posit an unknown called ‘life’ and use it to link various other phenomena, from digestion to sensation and the functioning of the glands. These phenomena consequently appear as interconnected, goal-oriented processes which do not exist either in an inanimate mechanism or in a corpse. In keeping with the empiricist roots of the analogy, however, no ontological claims are made about the nature of this vital principle, and no attempts are made to directly causally connect such a principle and observable phenomena. The role of the “Newtonian analogy” thus brings together diverse schools of thought, and cuts across a surprising variety of programs, models and practices in natural philosophy. (shrink)

Denis Diderot’s natural philosophy is deeply and centrally ‘biologistic’: as it emerges between the 1740s and 1780s, thus right before the appearance of the term ‘biology’ as a way of designating a unified science of life (McLaughlin), his project is motivated by the desire both to understand the laws governing organic beings and to emphasize, more ‘philosophically’, the uniqueness of organic beings within the physical world as a whole. This is apparent both in the metaphysics of vital matter he puts (...) forth in works such as D’Alembert’s Dream (1769) and the more empirical concern with the mechanics of life in his manuscript Elements of Physiology, on which he worked during the last twenty years of his life. This ‘biologism’ obviously presents the interpreter of Diderot with some difficulties, notably as regards his materialism, given that contemporary forms of materialism have on the contrary strongly rejected notions of emergence, vitalism, teleology and any concepts appealing to unique, irreducible features of organisms. In response, some have described him as a ‘holist’ (Kaitaro) while others have emphasized his materialist, naturalist project (Bourdin, Wolfe). In what follows I examine a little-known aspect of Diderot’s articulation of his biological project: his statement in favour of epigenesis within the short but suggestive Encyclopédie article “Spinosiste.” Diderot was, of course, a partisan of epigenesis (the developmental-biological theory opposed to preformation, according to which beings develop by successive adjunction of layers of matter), but why include a statement in favour of a particular biological (or developmental) theory within an entry dealing with a philosopher, Spinoza, who does not seem to have been concerned at all with the specific properties of living beings, how they grow from embryonic to developed states, and so on? By trying to answer this question I also try and locate Diderot’s biological project in relation to what will become, in the years after his death, the project for a science called ‘biology’, with figures such as Treviranus and Lamarck. For it is not clear that the two can be easily correlated or causally linked: Diderot’s ‘epigenetic Spinozism’ is a different conceptual entity from what we find in histories of biology. (shrink)

Sensibility, in any of its myriad realms – moral, physical, aesthetic, medical and so on – seems to be a paramount case of a higher-level, intentional property, not a basic property. Diderot famously made the bold and attributive move of postulating that matter itself senses, or that sensibility (perhaps better translated ‘sensitivity’ here) is a general or universal property of matter, even if he at times took a step back from this claim and called it a “supposition.” Crucially, sensibility is (...) here playing the role of a ‘booster’: it enables materialism to provide a full and rich account of the phenomena of conscious, sentient life, contrary to what its opponents hold: for if matter can sense, and sensibility is not a merely mechanical process, then the loftiest cognitive plateaus are accessible to materialist analysis, or at least belong to one and the same world as the rest of matter. This was noted by the astute anti-materialist critic, the Abbé Lelarge de Lignac, who, in his 1751 Lettres à un Amériquain, criticized Buffon for “granting to the body [la machine, a common term for the body at the time] a quality which is essential to minds, namely sensibility.” This view, here attributed to Buffon and definitely held by Diderot, was comparatively rare. If we look for the sources of this concept, the most notable ones are physiological and medical treatises by prominent figures such as Robert Whytt, Albrecht von Haller and the Montpellier vitalist Théophile de Bordeu. We then have, or so I shall try to sketch out, an intellectual landscape in which new – or newly articulated – properties such as irritability and sensibility are presented either as an experimental property of muscle fibers, that can be understood mechanistically (Hallerian irritability, as studied recently by Hubert Steinke and Dominique Boury) or a property of matter itself (whether specifically living matter as in Bordeu and his fellow montpelliérains Ménuret and Fouquet, or matter in general, as in Diderot). I am by no means convinced that it is one and the same ‘sensibility’ that is at issue in debates between these figures (as when Bordeu attacks Haller’s distinction between irritability and sensibility and claims that ‘his own’ property of sensibility is both more correct and more fundamental in organic beings), but I am interested in mapping out a topography of the problem of sensibility as property of matter or as vital force in mid-eighteenth-century debates – not an exhaustive cartography of all possible positions or theories, but an attempt to understand the ‘triangulation’ of three views: a vitalist view in which sensibility is fundamental, matching up with a conception of the organism as the sum of parts conceived as little lives (Bordeu et al.); a mechanist, or ‘enhanced mechanist’ view in which one can work upwards, step by step from the basic property of irritability to the higher-level property of sensibility (Haller); and, more eclectic, a materialist view which seeks to combine the mechanistic, componential rigour and explanatory power of the Hallerian approach, with the monistic and metaphysically explosive potential of the vitalist approach (Diderot). It is my hope that examining Diderot in the context of this triangulated topography of sensibility as property sheds light on his famous proclamation regarding sensibility as a universal property of matter.

Reshaping the neo-Aristotelian doctrines about the human soul was Descartes’s most spectacular enterprise, which gave birth to some of the sharpest debates in the Republic of Letters. Neverthe- less, it was certainly Descartes’s intention, as already expressed in the Discours de la méthode, to show that his new metaphysics could be supplemented with experimental research in the field of medicine and the conservation of life. It is no surprise then that several natural philosophers and doctors, such as Henricus Regius from (...) Utrecht, who had studied in Padua with William Harvey, rallied in support, in order to gain a more substantial theoretical basis for their research. Taking as his ground some general metaphysical assumptions, such as the existence of God, the immortality of the soul, and perhaps the separability of the pure understanding, Regius intended to secure a new philosophy of man, which was able to reflect his medical interests and complement his account of human nature. This is the story that is now gaining currency, and it is surely accurate, at least in part. Desmond Clarke has recently defended the same view1, based on the remarkable studies of the Utrecht scholars Theo Verbeek and Erik-Jan Bos. Here I would like to challenge some aspects of this view and ask how Regius, who was perceived as the philosopher most closely associated with Descartes, became a betrayer of his mentor. (shrink)
