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.

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.

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)

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)

According to the standard view, Montaigne’s Pyrrhonian doubts would be in the origin of Descartes’ radical Sceptical challenges and his cogito argument. Although this paper does not deny this influence, its aim is to reconsider it from a different perspective, by acknowledging that it was not Montaigne’s Scepticism, but his Stoicism, which played the decisive role in the birth of the modern internalist conception of subjectivity. Cartesian need for certitude is to be better understood as an effect of the Stoic (...) model of wisdom, which urges the sage to build an inner space for self-sufficiency and absolute freedom.

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.”.

A chapter on the specifically 'medical' Epicureanism of La Mettrie, connecting his materialist approach to mind-body issues and his hedonistic ethics.

Gassendi holds that matter is intrinsically active - it possesses an innate active force or power. This paper explains what that active power consists in and why Gassendi adopted this view.

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)

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)

It is often suggested that certain forms of early modern philosophy are naturalistic. Although I have some sympathy with this description, I argue that applying the category of naturalism to early modern philosophy is not useful. There is another category that does most of the work we want the category of naturalism to do ? one that, unlike naturalism, was actually used by early moderns.

From Hegel to Engels, Sartre and Ruyer (Ruyer, 1933), to name only a few, materialism is viewed as a necropolis, or the metaphysics befitting such an abode; many speak of matter’s crudeness, bruteness, coldness or stupidity. Science or scientism, on this view, reduces the living world to ‘dead matter’, ‘brutish’, ‘mechanical, lifeless matter’, thereby also stripping it of its freedom (Crocker, 1959). Materialism is often wrongly presented as ‘mechanistic materialism’ – with ‘Death of Nature’ echoes of de-humanization and hostility to (...) the Scientific Revolution (which knew nothing of materialism!), also a powerful Christian theme in Cudworth, Clarke and beyond (Overhoff, 2000). Here I challenge this view, building on some aspects of Israel’s Radical Enlightenment concept (Israel, 2001), which has been controversial but for my purposes is a useful claim about the dissemination of a home-grown Spinozism, sometimes reformulated as an ontology of the life sciences, an aspect Israel does not address (compare Secrétan et al., eds., 2007; Citton, 2006). First, I examine some ‘moments’ of radical Enlightenment materialism such as La Mettrie and Diderot (including his Encyclopédie entry “Spinosiste”), but also anonymous, clandestine texts such as L’Âme Matérielle, to emphasize their distinctive focus on the specific existence of organic beings. Second, I show how this ‘embodied’, non-mechanistic character of Enlightenment ‘vital materialism’ makes it different from other episodes, and perhaps more of an ethics than is usually thought (also via the figure of the materialist as ‘laughing philosopher’). Third, I reflect on what this implies for our image of the Enlightenment – no longer a Frankfurt School and/or Foucaldian vision of ‘discipline’, regimentation and order (as in Mayr, 1986) – but ‘vital’, without, conversely, being a kind of holist vitalism “at odds with the universalizing discourse of Encyclopedist materialism, with its insistence on the uniformity of nature and the universality of physical laws” (Williams, 2003): vital materialism is still materialism. Its ethics tends towards hedonism, but its most radical proponents (Diderot, La Mettrie and later Sade) disagree as to what this means. (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)

Article où l'on soutient l'incompatibilité du mérite et de l'utilité commune, à partir d'une lecture de la seconde proposition du premier article de la déclaration de 1789.

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.

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)

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.

The materialist approach to the body is often, if not always understood in ‘mechanistic’ terms, as the view in which the properties unique to organic, living embodied agents are reduced to or described in terms of properties that characterize matter as a whole, which allow of mechanistic explanation. Indeed, from Hobbes and Descartes in the 17th century to the popularity of automata such as Vaucanson’s in the 18th century, this vision of things would seem to be correct. In this paper (...) I aim to correct this inaccurate vision of materialism. On the contrary, the materialist project on closer consideration reveals itself to be, significantly if not exclusively, (a) a body of theories specifically focused on the contribution that ‘biology’ or rather ‘natural history’ and physiology make to metaphysical debates, (b) much more intimately connected to what we now call ‘vitalism’ (a case in point is the presence of Théophile de Bordeu, a prominent Montpellier physician and theorist of vitalism, as a fictional character and spokesman of materialism, in Diderot’s novel D’Alembert’s Dream), and ultimately (c) an anti-mechanistic doctrine which focuses on the unique properties of organic beings. To establish this revised vision of materialism I examine philosophical texts such as La Mettrie’s Man a Machine and Diderot’s D’Alembert’s Dream; medical entries in the Encyclopédie by physicians such as Ménuret and Fouquet; and clandestine combinations of all such sources (Fontenelle, Gaultier and others). (shrink)

There is an enduring story about empiricism, which runs as follows: from Locke onwards to Carnap, empiricism is the doctrine in which raw sense-data are received through the passive mechanism of perception; experience is the effect produced by external reality on the mind or ‘receptors’. Empiricism on this view is the ‘handmaiden’ of experimental natural science, seeking to redefine philosophy and its methods in conformity with the results of modern science. Secondly, there is a story about materialism, popularized initially by (...) Marx and Engels and later restated as standard, ‘textbook’ history of philosophy in the English-speaking world. It portrays materialism as explicitly mechanistic, seeking to reduce the world of qualities, sensations, and purposive behaviour to a quantitative, usually deterministic physical scheme. Building on some recent scholarship, I aim to articulate the contrarian view according to which neither of these stories is true. On the contrary, empiricism turns out to be less ‘science-friendly’ and more concerned with moral matters; materialism reveals itself to be, in at least a large number of cases, a ‘vital’, anti-mechanistic doctrine which focuses on the unique properties of organic beings. This revision of two key philosophical episodes should reveal that our history of early modern philosophy is dependent to a great extent on ‘special interests’, whether positivistic or Kantian, and by extension lead us to rethink the relation and distinction between ‘science’ and ‘philosophy’ in this period.

A belief in a firm correspondence between objects, ideas, and their representation in language pervaded the works of Anne Robert Jacques Turgot

(1727–1781) in 1750. This conviction is particularly manifest in Turgot’s sharp critique of Berkeley’s philosophical system and his remarks on Maupertuis’s reconstruction of the origin of language. During the 1750s Turgot’s epistemological views underwent a change, apparent in two of his contributions to the Encyclopédie: the entries Existence and Étymologie (1756). These articles included a reassessment of Berkeleyan immaterialism, facing (...) an ultimate crisis of definition and representation. A similar development may be traced in contemporary works by Condillac and Diderot. Turgot’s Encyclopédie entries also envisaged a new science, an archeology of the human mind aided by the examination of linguistic development and change. This entailed the scientific verification of conjectures in any historical account of ideas, turning etymological

and psychological inquiries into what Turgot termed ‘experimental metaphysics’. (shrink)

In July 1759 the French philosopher Andre´ Pierre Le Guay de Prémontval (1716-1764) published in Berlin a diatribe against the excessive and incorrect use of French in the Prussian capital. Far from being a mere guide to linguistic style, the Préservatif contre la corruption de la langue françoise generated a heated debate, attested by an official threat to ban its publication. The personal animosity between Prémontval and the perpetual secretary of the Berlin Academy, Jean Henri Samuel Formey (1711-1797) was amply (...) demonstrated over the pages of the Préservatif, offering a rare insight into the complex web of social and intellectual tensions in mid eighteenth-century Berlin and its Academy of Sciences. At stake were the social status and the philosophical outlook of local Huguenots, compared to that of French philosophers who were granted asylum in Prussia by Frederick II. The debate also concerned the issues of academic freedom in an absolutist regime, the material production and distribution of texts, conduct and etiquette in the Republic of Letters and the formation of group identities in eighteenth-century Germany. Drawing on manuscripts preserved in Berlin, Göttingen and Krakow, this article traces the development of the controversy and the reception of Prémontval’s work by both French- and German- writing authors at the Berlin Academy and beyond its confines.
