This monograph details the entire scientific thought of an influential natural philosopher whose contributions, unfortunately, have become obscured by the pages of history. Readers will discover an important thinker: Burchard de Volder. He was instrumental in founding the first experimental cabinet at a European University in 1675. The author goes beyond the familiar image of De Volder as a forerunner of Newtonianism in Continental Europe. He consults neglected materials, including handwritten sources, and takes into account new historiographical (...) categories. His investigation maps the thought of an author who did not sit with an univocal philosophical school, but critically dealt with all the ‘major’ philosophers and scientists of his age: from Descartes to Newton, via Spinoza, Boyle, Huygens, Bernoulli, and Leibniz. It explores the way De Volder’s un-systematic thought used, rejected, and re-shaped their theories and approaches. In addition, the title includes transcriptions of De Volder's teaching materials: disputations, dictations, and notes. Insightful analysis combined with a trove of primary source material will help readers gain a new perspective on a thinker so far mostly ignored by scholars. They will find a thoughtful figure who engaged with early modern science and developed a place that fostered experimental philosophy. (shrink)

In this article, I intervene in a long-standing debate over the alleged assumption and teaching of Spinozist ideas by the Dutch philosopher and scientist Burchard de Volder (1643–1709). I discuss De Volder’s position with respect to three main topics (necessitarianism, substance monism, and biblical interpretation), as well as the use his student Jacob Wittich made of De Volder’s ideas in Wittich’s highly controversial De natura Dei (1711). Eventually, I argue that De Volder was certainly a (...) sympathizer of Spinoza, accepted necessitarianism, and considered Spinoza a reliable interpreter of Descartes in physics, even if he did not accept Spinoza’s monist metaphysics, nor his biblical hermeneutics.

In this chapter I provide a reconstruction of the contents of the lectures provided by Burchard de Volder by means of experiments at Leiden, in the years 1676–1678, as well as of the natural-philosophical interpretation he provided of the experimental evidences he gained. Such lectures, mostly based on the experiments described by Boyle, served De Volder to teach natural-philosophical ideas which he borrowed from Descartes, and which he re-interpreted in the light of Archimedes’s hydrostatics.

These notes contain an annotated edition of the only four extant letters of Burchard de Volder to Philipp van Limborch. In the first letter De Volder provides Van Limborch with some information about the subscription to the Dordrecht Confession of Faith by professors. In the second letter De Volder comments upon Van Limborch’s De veritate religionis Christianae. This letter is interesting as it provides insights into De Volder’s views on religion and theology. The third letter (...) served as a cover letter for De Volder’s sending to Van Limborch a copy of the honestum testimonium on Jacobus Arminius that was requested by Arminius’s widow in 1611. In the fourth letter Volder comments upon the visit that Pieter Burman had paid him. The visit was an episode in the quarrel between Pieter Burman, his brother Frans Burman jr., and Van Limborch, caused by Van Limborch’s remark, in his Theologia Christiana, that Frans Burman sr. had used Spinoza’s words while treating the issue of divine omnipotence in his Synopsis theologiae.

Leibniz accepts causal independence, the claim that no created substance can causally interact with any other. And Leibniz needs causal independence to be true, since his well-known pre-established harmony is premised upon it. So, what is Leibniz’s argument for causal independence? Sometimes he claims that causal interaction between substances is superfluous. Sometimes he claims that it would require the transfer of accidents, and that this is impossible. But when Leibniz finds himself under sustained pressure to defend causal independence, those are (...) not the reasons that he marshals in its defense. Instead, deep into his long correspondence with Burchard de Volder, he gives a different sort of argument, one that has gone nearly unnoticed by commentators and has not yet been properly understood. In part, this is because the argument develops slowly over four years of correspondence. It emerges in early 1704, but it is formulated tersely and appears murky unless understood in light of Leibniz and De Volder’s tangled exchanges. There Leibniz argues that, on his distinctive ontology of an infinity of created substances, no two created substances could possibly causally interact, for roughly the same reasons that some Cartesians like De Volder deny interaction between minds and bodies on their substance dualist ontology. In this paper I draw out this lost argument, explain it and the metaphysics on which Leibniz builds it, and untangle Leibniz and De Volder’s exchanges concerning causation from which this argument results.

The sixth chapter focuses on the evolution of Cartesianism in the last quarter of the seventeenth century in Leiden and Amsterdam, against the background of the emergence of alternative views in natural philosophy capable of replacing it as a dominant paradigm, namely, the experimental philosophy of Robert Boyle and the mathematical-experimental approach of Huygens and Newton. The last evolution of Cartesianism is reconstructed in this chapter by considering the ‘Cartesian empiricism’ of Burchard de Volder, and the reflections on (...) the language of philosophy and practical disciplines by De Raey in Amsterdam, where he moved in 1669. In 1675 De Volder established the Leiden Theatrum physicum. There he performed experiments in order to teach the principles of a mechanical philosophy largely inspired by Descartes but open to the use of experimental and mathematical evidences in the formulation of natural laws. A similar approach was in fact assumed in the same years by Wolferd Senguerd, who used the Theatrum to perform experiments in pneumatics to teach some of the principles of his eclectic worldview, encompassing some Cartesian principles (such as that of the circularity of movement), but also rejecting the vortex theory. Yet, only De Volder developed a foundational theory for the basic principles of mechanicism, namely, the assumption that every phenomenon can be explained by the notions of matter and movement alone. This was the result of a movement internal to Cartesianism, as De Volder not only reacted (positively) to the emergence of an experimental-mathematical natural philosophy, but was also involved in the defence of Cartesianism against the Censura philosophiae cartesianae of PierreDaniel Huet (1689), in which Descartes’s metaphysics is rejected as inconsistent given its very foundation on doubt and cogito. The intermingling of these different issues resulted, in De Volder’s hands, in a further de-metaphysicisation of physics – as metaphysics cannot provide a justification for the laws of motion – and in the narrowing of the scope of foundationalism, which can only sanction the psychological character of clarity and distinction as a criterion for internal truth, defined in terms of indubitability only. Accordingly, for De Volder metaphysics cannot demonstrate, on a Cartesian basis, that phenomena are actually ruled by the principles of mechanism: insofar as, for him, metaphysics has a prominent reflective role, and loses its status as justification of the absolute truth of scientific statements. This process can be labelled as the transition from foundationalism to philosophy of science and does not characterise only his ‘Cartesian empiricism’. In Amsterdam, De Raey was, over the same years, developing his Cogitata de interpretatione (1692), embodying one of the first, self-standing philosophical considerations of language. Still maintaining his separation thesis, and attacking Hobbes and the radical Cartesians, in this text he aimed to clarify how words meaning sensory data and abstract notions (such as those of mathematics) can be used in philosophy. Rather than setting a method for how to use mental faculties, De Raey aimed, at the end of his career, to provide an updating of the linguistic meanings of scientific vocabulary, namely, a reflection rather than a justification of science.

The seventh chapter focuses on the aftermath of the decline of Cartesianism as a leading force in the Dutch academic context. After De Volder and De Raey, indeed, only Ruardus Andala in Franeker carried on the teaching of Cartesian physics (which he taught by commenting upon Descartes’s Principia) and metaphysics, mainly for the sake of contrasting Spinozism and other forms of radical Cartesianism. Thus, Descartes’s philosophy came a dead end on the eve of the eighteenth century. Yet, Leiden Cartesianism (...) and the Leiden experimental tradition (which could include, after De Volder and Senguerd, the activities of Herman Boerhaave), favoured the introduction of Newtonianism as the standard in teaching natural philosophy. This was carried out by ’s Gravesande, who used logic and metaphysics (including rational theology), that is, the chief foundational disciplines in the Cartesian tradition, to introduce students to and justify the assumptions (methodological and ontological) of a Newtonian approach in natural philosophy. This had two outcomes. On the one hand, his arguments in metaphysics (i.e. ontology) have the function of clarifying which objects natural philosophy can investigate. These are natural laws, whose ultimate source in substances or modes cannot be ascertained by intellect alone, as they depend on the power of God. On the other, given the fact that experience is our only means of grasping such laws (which are then mathematically handled) he provides a rational-theological justification of experiential evidence, as capable of providing us with a degree of certainty equal to mathematical evidence. As for the Cartesians, this is still the paradigm of scientific knowledge. Accordingly, with the introduction of Newtonianism foundational disciplines such as logic and metaphysics (including rational theology) served as a justification for and a reflection on a given scientific methodology. Thus, philosophy started to be actually detached from the natural sciences, and to assume a subservient role with respect to them, as once it was the ancilla theologiae. (shrink)

Leibniz argues that Cartesian extension lacks the unity required to be a substance. A key premise of Leibniz’s argument is that matter is a collection or aggregation. I consider an objection to this premise raised by Leibniz’s correspondent Burchard de Volder and consider a variety of ways that Leibniz might be able to respond to De Volder’s objection. I argue that it is not easy for Leibniz to provide a dialectically relevant response and, further, that the difficulty (...) arises from Leibniz’s commitment to part-whole priority in the case of material wholes, a commitment not shared by De Volder. One major implication is that Leibniz relies on a bottom-up conception of material things, which makes his argument vulnerable to objections stemming from certain types of monist positions. (shrink)

Cartesian Empiricisms considers the role Cartesians played in the acceptance of experiment in natural philosophy during the seventeenth century. It aims to correct a partial image of Cartesian philosophers as paradigmatic system builders who failed to meet challenges posed by the new science’s innovative methods. Studies in this volume argue that far from being strangers to experiment, many Cartesians used and integrated it into their natural philosophies. Chapter 1 reviews the historiographies of early modern philosophy, science, and Cartesianism and their (...) recent critiques. The first part of the volume explores various Cartesian contexts of experiment: the impact of French condemnations of Cartesian philosophy in the second half of the seventeenth century; the relation between Cartesian natural philosophy and the Parisian academies of the 1660s; the complex interplay between Cartesianism and Newtonianism in the Dutch Republic; the Cartesian influence on medical teaching at the University of Duisburg; and the challenges chemistry posed to the Cartesian theory of matter. The second part of the volume examines the work of particular Cartesians, such as Henricus Regius, Robert Desgabets, Jacques Rohault, Burchard de Volder, Antoine Le Grand, and Balthasar Bekker. Together these studies counter scientific revolution narratives that take rationalism and empiricism to be two mutually exclusive epistemological and methodological paradigms. The volume is thus a helpful instrument for anyone interested both in the histories of early modern philosophy and science, as well as for scholars interested in new evaluations of the historiographical tools that framed our traditional narratives.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Dutch Cartesianism and the Birth of Philosophy of Science by Andrea StrazzoniAaron SpinkAndrea Strazzoni. Dutch Cartesianism and the Birth of Philosophy of Science. Berlin: Walter de Gruyter, 2019. Pp. ix + 245. Hardback, $124.99.Andrea Strazzoni's Dutch Cartesianism and the Birth of Philosophy of Science is a clear step forward in our understanding of the rise and fall of Cartesianism. The work, limited to the Dutch context with one (...) notable German excursion, covers roughly one hundred years starting from the 1630s. While the time frame is rather large in scope, the majority of the work is narrower in focus, with a heavy emphasis on the academic circles in mid-to-late seventeenth-century Leiden and Utrecht. It is thus a welcome addition to the growing body of literature dealing with the unique political, religious, and academic contexts in which Dutch Cartesians found themselves. While much of the book deals with the philosophy of Descartes and then Newton, Strazzoni is not concerned with giving any novel interpretations of either figure; instead, he sheds a great deal of light on a cast of characters who are only now coming to be appreciated for their contributions and influence on philosophical movements of the seventeenth and early eighteenth centuries. The book has two main explicit goals. First, Strazzoni wants to show why foundationalism came to play such a prominent role in Dutch Cartesian circles and what foundationalism's effects were. Second, through this examination, Strazzoni hopes to show that the multiplication of worldviews [End Page 154] shaped a new function for metaphysics and logic as tools for examining principles, which in turn determined a change in the function of philosophy itself that eventually gave birth to a kind of philosophy of science familiar to us today.Strazzoni divides this project into eight chapters, with a focus on six figures: Henricus Regius, Johannes Clauberg, Johannes de Raey, Arnold Geulincx, Burchard de Volder, and Willem Jacob's Gravesande. In addition to a brief overview of the goals and structure of the work, the first chapter includes a survey of how methodologies have changed in the history of philosophy and the history of the philosophy of science, which will be helpful background for those less familiar with the fields.The following two chapters deal with the crises that emerged in Utrecht and Leiden over the spread of Cartesian philosophy. In chapter 2, building on Theo Verbeek's work, Regius takes center stage. While some context of the Utrecht crisis is given, Strazzoni spends much of the chapter detailing how Regius's medical background led to a more empirical approach and lack of metaphysical foundation. While Regius's own controversial positions embroiled both himself and Descartes in the Utrecht Crisis, ripple effects spread to Leiden, resulting in prohibitions against discussions of Cartesian philosophy. In the third chapter, Strazzoni highlights a group of anti-Cartesians, with Jacob Revius as the primary antagonist, and the responses from De Raey and Clauberg. Clauberg, the subject of Strazzoni's only sustained discussion of Cartesianism from Germany, coordinated with de Raey on both a positive campaign of promotion and strategizing responses to the anti-Cartesian front. Outside of discussing Clauberg's explicit role in Leiden, Strazzoni studies his logic and Ontosophia, neatly explaining his shift to more metaphysical foundations.Chapters 4, 5, and 6 continue exploring the various approaches and roles for foundational philosophy in more detail, delving into how these controversies motivated renewed analysis of core Cartesian principles with integration into an academic curriculum in mind. Apart from de Raey's efforts to show that Cartesianism was aligned with Aristotelianism, Strazzoni claims a period of Cartesian physics without an explicit preoccupation with metaphysical questions, especially in light of the restrictions imposed by the curators of Leiden's university. However, as Spinoza and Hobbes came to prominence, multiplying the number of philosophical worldviews, foundational arguments were needed to combat them. Strazzoni highlights how varied these responses could be, as Geulincx's own take on foundations leaned heavily toward ethics rather than epistemology, metaphysics, or logic. However, the discussion of Geulincx is much broader, also including illuminating expositions of Geulincx's theology, epistemology, and metaphysics.Chapter 5 expounds further... (shrink)

Through a consideration of the philosophical debates occurring in the Dutch and Dutch-related intellectual framework in the early modern period, in the present study some alternatives in the foundation of philosophy and science have been highlighted and analysed. In conclusion, it is time to assess them in a more systematic manner. Each alternative entails a different view on foundational arguments, which may be grouped into theological, metaphysical, and logical ones. This research reveals the essential features of a philosophical milieu created (...) by Descartes and constituting the framework for the dissemination of Newtonian science in Europe, leading to the birth of a philosophy of science as the study of the foundations, assumptions, methods, and limits of the study of natural realms. In fact, one can recognise several reasons for such foundation: on a general level, the need of providing philosophy with a secure foundation against the ‘sceptical crisis’ of the sixteenth and seventeenth centuries highlighted by Richard Popkin. More specifically, however, the foundation of Cartesian and Newtonian philosophy and science served to defend the conceptual premises of new ways of thinking in an academic context, demonstrating the validity of such new ways and rejecting the commonsensical and non-explanatory assumptions of Scholastic philosophy, and, in the case of ’s Gravesande, the speculative character of Descartes’s physics itself.

The Quarrel over Swammerdam’s Posthumous Works reconstructs the vicissitudes of Johannes Swammerdam’s Biblia naturae, a pivotal collection of writings in the history of science. Bequeathed to the polymath Melchisédech Thévenot, the manuscripts and drawings of the treatises constituting this collection were instead kept by the editor Hermann Wingendorp after Swammerdam’s death (1680), triggering a quarrel over their publication. By analysing Swammerdam’s scientific legacy and by offering an edition of the correspondence testifying to the efforts towards such publication, this book sheds (...) light on the editorial history and intellectual context of Swammerdam’s Biblia. This reveals not only an intricate plot of authorized and unauthorized attempts to publish it, but also an exchange of scientific texts and instruments in the late seventeenth century. (shrink)

When was philosophy of science born? And why? This book aims to answer these questions. Simply put, philosophy of science was born in seventeenth-century Dutch universities, where the introduction of Cartesian ideas called for philosophical reflection upon the validity, method, and concepts of natural philosophy. The disciplines which fulfilled this role were metaphysics and logic. The process was neither short nor straightforward, nor – admittedly – easily grasped through such a generalisation. As a matter of fact, philosophy of science has (...) existed since antiquity, or for as long as philosophers have provided reflections on such topics. On the other hand, the institutional fragmentation of philosophical and scientific disciplines in the modern era has made it increasingly easy to distinguish between ‘philosophy’ and ‘science’, and for philosophers to provide reflections on the natural sciences. This book stands at the crossroads: namely, it disentangles the ways in which metaphysics and logic became functional for such reflection, and, forthwith, they began to be detached from what was labelled ‘natural philosophy’. This is the reason why this book offers a study of Dutch Cartesianism. Dutch universities were the first where Descartes’s ideas became official matter of teaching and came to reshape the function of metaphysics and logic. So that one can meaningfully ascribe the role of ‘philosophy of science’ to them, and to see this role at work in lectures, disputations, treatises. Again, this is a simplification. Philosophy of science did not appear abruptly, nor was it related only to a transformation of metaphysics, logic, and natural philosophy: its emergence coincided with a rethinking of the foundations of all philosophical disciplines. Philosophy of science appeared, first, as a reflection on philosophy itself, carried out in different disciplines. More precisely, it emerged as a renewed foundation of all philosophical disciplines, serving to guarantee the reliability of their methodologies and concepts, namely, to grant their status as indubitable scientiae.

Since the 1960s the integration of the history of science and the philosophy of science has been substantiated by the presence of university departments offering a curriculum of studies catering to both disciplines. At Princeton University, Charles Gillespie established the first curriculum of studies in the history and philosophy of science – henceforth HPS – in 1960, with the purpose of attracting students to the study of the history of science. In Princeton, history of science was taught by John E. (...) Murdoch, while Hilary Putnam gave courses in philosophy of science. At Indiana University it was a historian of philosophy, Norwood Russell Hanson, who established the first department of HPS, hosting the teaching of historian of science Alfred Rupert Hall. Eventually, the actual integration of history and philosophy of science was brought about by the appearance of Thomas Kuhn’s Structure of Scientific Revolutions (1962), which, drawing attention to the notion of paradigm in scientific theories, favoured the marriage between historical and philosophical analysis of science. Since 1960s, HPS has flourished, and nowadays at least five universities in the United Kingdom and sixteen in the United States offer degrees in HPS (Mauskopf/Schmaltz 2012, pp. 1–10). More recently, kindred approaches have emerged, such as the ‘integrated HPS’ (&HPS), endorsed in some international conferences, which aims at merging the two disciplines rather than offering philosophical insights into the history of science and vice versa.

The present study defines the function of the foundation of science in early modern Dutch philosophy, from the first introduction of Cartesian philosophy in Utrecht University by Henricus Regius to the acceptance of Newtonian physics by Willem Jacob ‘s Gravesande. My main claim is that a foundation of science was required because the conceptual premises of new ways in thinking had to be justified not only as alternatives to the established philosophical paradigms or as an answer to the “sceptical crisis” (...) signalled by Richard Popkin, but also in order to be introduced in the academia. This being my general thesis, different kinds of foundation of scientific knowledge are analysed in the light of the specific problems philosophers had to face. To this end, foundational theories are analysed in the light of 1) the overall aim of their philosophy, 2) the relations of disciplines they thought out, 3) what they regarded as scientific knowledge. Through this analysis, I assess that the foundation of science was carried out by metaphysical, logical and theological arguments, which fitted the needs of answering the didactical and introductory requirements of new paradigms, assessed the reliability of new methodology in leading us to grasp the truth, and provided philosophy with its conceptual apparatus. Finally, I demonstrate that a philosophy of science as a reflection on the principles, methods, concepts and application of modern science emerged in the Dutch Republic. (shrink)

Paul Lodge’s excellent new contribution to the Yale Leibniz series collects together the entirety of the Leibniz-De Volder correspondence, totaling some thirty-three letters, together with a generous selection of relevant excerpts from Leibniz’s concurrent correspondence with Johann Bernoulli, which Lodge has helpfully interspersed throughout. As with previous volumes in the series, the texts appear in the original language, in this case Latin, together with an English translation on opposing pages. Lodge’s transcriptions reflect his careful study of all the available (...) manuscripts and represent a significant improvement over the existing versions in GP II (Leibniz-De Volder) and GM III (Leibniz-Bernoulli).

Between 1698 and 1706 Leibniz was engaged in one of his most interesting correspondences, with the Dutch philosopher and physicist Burcher de Volder. The two men were concerned primarily with the question of how the motion of bodies can be explained without appeal to the direct intervention of God. Leibniz presented a naturalistic account of motion to De Volder, but failed to convince him of its adequacy. I shall examine one reason for this failure - the disagreement that (...) arose over the issue of whether there is a substance whose nature is constituted by extension. (shrink)

En el presente artículo se estudia la prueba a priori de Leibniz en favor de la medición de las fuerzas en su correspondencia con De Volder. El objetivo general es demostrar que este argumento no tiene privilegio para entender la noción leibniziana de acción primitiva de las sustancias. En primer lugar, se analiza el contexto histórico y conceptual que permite comprender dicha prueba a priori. En particular, se explica por qué Leibniz moviliza este argumento y se especifican las nociones (...) allí utilizadas, tales como la de fuerza, acción y acción formal. En segundo lugar, se estudia la estructura de la prueba para analizar su validez. Para ello, se presentan los principales problemas que fueron objeto de las críticas de De Volder y se muestra bajo qué supuesto la prueba es sólida. En tercer lugar, se examina el alcance de esta prueba en relación con el argumento a posteriori y se argumenta que no tiene ninguna ventaja en lo que concierne a la comprensión de la metafísica de Leibniz.

The object of the first part of this paper is to establish the relationships which Leibniz establishes between metaphysical action and dynamic action, in the light of how he elaborates the concept of dynamic action in the texts from the years 1689-90 and in particular of Dynamica de potentia. Once the interdependence of these two notions is revealed, the ambivalence of action can be seen as a means to a new understanding, based on the Dynamics, of the relationships between substance (...) and phenomenon. The correspondence with De Volder is the ideal setting for this clarification. (shrink)

Gravity was a major theme in the seventeenth century scientific discussion. Trendsetters in the renewal of natural science were Galilei and Descartes. The first required a unified theory of all phenomena of gravity ; the second provided one with his vortex-hypothesis, which explained gravity by the mechanical push of subtile bodies of the vortex. This conception was tested and generally followed by Christiaan Huygens, whereas Newton presented the laws of the so called 'attraction' by which he did not at all (...) indicate the causes of those laws of motion. Spinoza comes on the scene of polemics as a critical Cartesian. Motion (of which downward motion of heavy bodies is only one instance) was explained by Descartes, but not so the rest of bodies or the equilibrium in the power relation between opposite forces, neither the reason why in some cases the particles form a hard body. Full fledged mechanism and consistent determinism lead Spinoza to account for rest and solidity in the same way, namely by means of the pressure of small and mostly unvisible bodies in the whirling environment. This paradoxical law was acknowledged as a real and important contribution to physical science by the Dutch spinozistic Cartesians Cuffeler and Overkamp, by the mathematician De Volder, by Spinoza's younger friend Tschirnhaus and in France by Malebranche. By the end of the century it was quite normal to speak about „the gravity of the air” and to consider the gravity of gross bodies as an illusion. (shrink)

Leibniz’s ‘new science of dynamics’ is typically taken to have been completed in the late monadological metaphysics. On this view, stemming from Martial Gueroult and continuing in the recent interpretations of Robert Adams and Pauline Phemister, Leibniz accomplished his dynamics in his later account of physical forces as merely phenomenal modifications of monadic, metaphysical forces. This paper argues, by contrast, that Leibniz considered the dynamics to be an unfinished project: this is evident in statements from throughout his mature period until (...) his final months. Two possible reasons for the non-completion of the dynamics are discussed. The first is that his encounter with the superior physics of Newton’s Principia caused Leibniz to continually defer his own contribution. I argue, however, in favour of a second reason: that there are philosophical difficulties inherent in the science of dynamics that prevented its completion. These difficulties are found in the relation of dynamics to metaphysics, and in the more fundamental split within dynamics, into the doctrine of primitive and derivative forces. Through three late exchanges with de Volder, Wolff and Des Bosses, I show that the relation of primitive and derivative forces remained an unsolved – although not in principle unsolvable – problem for Leibniz.

This article aims to treat the question of the reality of Leibniz’s infinitesimals from the perspective of their application in his account of corporeal motion. Rather than beginning with logical foundations or mathematical methodology, I analyze Leibniz’s use of an allegedly “instantiated” infinitesimal magnitude in his treatment of dead force in the Specimen Dynamicum. In this analysis I critique the interpretive strategy that uses the Leibnizian distinction, drawn from the often cited 1706 letter to De Volder, between actual and (...) ideal for understanding the meaning of Leibniz’s infinitesimal fictionalism. In particular, I demonstrate the ambiguity that results from sticking too closely with the idea that ideal mathematical terms merely “represent” concrete or actual things. In turn I suggest that, rather than something that had to be prudentially separated from the realm of actual things, the mathematics of infi nitesimals was part of how Leibniz conceived of the distinction between the actual and ideal within the Specimen Dynamicum.

In the following paper I would like to try to expound on a concept quite important in the philosophy of Leibniz – that of the “Monas Dominans”. In particular, I would like to approach this subject in the first place by means of considerations of a “historical-genetic” nature, while in the second part of my work I propose to put forward some possible interpretations of it. In both cases I will try to compare my ideas with those of recent studies (...) on this theme. The difficulties are numerous; first of all, the texts published to date in which Leibniz introduces and presents his doctrine of the “Monas Dominans” are relatively few, especially if compared to the space given to other elements of his philosophical system; secondly, if on the one hand the general intention put forward by Leibniz through the introduction of this doctrine is clear enough (the Monas Dominans renders “One” in the Machine the “corporeal substance”, that is the “Animal”, as found in the letter to De Volder of June 1703 to which scholars often make reference), on the other hand, when one tries to clarify its details and consider its implications one immediately runs into the same difficulties already pointed out in other studies (regarding, for example, the definition of “corporeal substance”, the relationship between the “Monas dominans” and the “innumerable subordinate monads” that form the “Organic Machine”, etc.). A primary idea I will try to present in this work regards the highlighting in the work of Leibniz of a close correlation between the appearance of the expression “organism” and that of the expression “Monas Dominans”.

It is well known that Leibniz believes that the motion of bodies is caused by an internal force.1 Moreover, he distinguishes between two kinds of force that are associated with bodies, which he calls primitive and derivative forces respectively. My aim is to explain Leibniz’s account of the relation between these two kinds of force, and to address a puzzle that arises in connection with this relation. In fact Leibniz speaks of two different kinds of derivative force. The first, and (...) most fundamental, kind of derivative force is the momentary tendency to move from one perception to another within a simple substance, or monad. Sometimes these are called “appetitions”.2 The second kind are the forces of bodies that are found in the mechanical explanations of Leibnizian Dynamics.3 We shall be concerned primarily with the latter in what follows. However, the derivative forces of monads will also play an important role in the discussion. As one might expect, Leibniz holds that derivative forces are derived from the primitive ones. This idea is more usually expressed in terms of the notion of modification. Thus, derivative forces are said to be “nothing but the modifications and results of primitive forces”4 and to “arise as shapes arise from modification of extension”.5 Here it is natural to assume that Leibniz understands the relation between primitive and derivative force in something like the way in which Descartes understood the relation between modes of extended and thinking substances and the substances themselves, namely as particular ways of being an extended or thinking thing that inhere in their subjects.6 Although this account of derivative forces as modifications of primitive forces may seem plausible at first, difficulties arise when we try to understand how it could apply to the derivative forces in Leibnizian bodies. For it seems to be in conflict with two further aspects of Leibniz’s philosophy. Both can be found in the following passage from a letter to De Volder of 1705.. (shrink)

The doctrine of natural machines, of organisms, of composite substances, assumes a marked consistency in Leibniz starting from his mature years (let us say, from the publishing of New System in 1965 onwards). There is no doubt, therefore, that for a full explanation of the conceptual content of the reflection of Leibniz on the nature of living substances we must turn to the “classic” places in which it took form: from the letters to De Volder and Lady Masham of (...) the early 1700s, to the Nouveaux Essais, to Animadversiones contra Stahl and, naturally to Princìpes de la Nature et de la Grace and to the Monadologie. We can in any case ask what are the elements of specific difference are that emerge in this vast doctrinal corpus regarding those elements of the theory of the living being that had already appeared with a certain frequency in the texts of the early 1780s. Put in other words: what link of continuity subsists between the proto-theory of the living being of the ‘80s and that of the mature years (let us say from New System on)? Or, overturning the formulation of the problem: what elements of discontinuity suddenly break into Leibniz’s reflections from the second half of the ‘90s compared to the immediately preceding phases of his thought? Certainly, the monads, the machines of nature. But is it possibile to focus even more clearly the lens of our observations? I mean: after a decade of intense theoretical debate on the nature of corporeal substances, on organisms, on machines of nature, is it possibile to sketch a historical picture that accounts in a coherent manner for the development of Leibniz's thought in relation to the questions raised here?

Seine Kritik an Descartes' Auffassung vom Körper gründet Leibniz bekanntlich auf Erörterungen zur Teilbarkeit und Ausdehnung. Obgleich jene Argumentation im Fokus einer Auseinandersetzung mit Leibniz' Metaphysik angesiedelt werden muss, ist sie bisher nicht recht verstanden worden. Mein Anliegen hier ist im Kern, Leibniz' Gedankengang zu explizieren und dessen Stichhaltigkeit auszuleuchten. Das Argument, um das es geht, ist wohl am ehesten aus der Darlegung in Leibniz' Korrespondenz mit Antoine Arnauld bekannt, findet sich jedoch zudem im späteren Briefwechsel mit De Volder. (...) Neben Parallelen gibt es zwischen den Verfahrensweisen, die Leibniz in den zwei Korrespondenzen jeweils favorisiert, gleichwohl derart signifikante Differenzen, dass es nicht unbegründet scheint, ihm auch zwei Argumentationslinien zuzuschreiben -die Unterschiede dieser Linien werde ich im Folgenden auch hinsichtlich ihres Entstehungszusammenhangs beleuchten und einen Ausblick auf weitere Forschungserfordernisse wagen.

RésuméCet article propose de concevoir le dissensus moins comme le constat d’un désaccord irréductible que comme le point de départ d’un processus visant à élaborer un territoire épistémique commun. Dans le travail argumentatif de confrontation des désaccords, il ne s’agit pas d’identifier le dispositif qui conduit à un accord via la délibération rationnelle. Il s’agit plutôt de comprendre comment le dissensus permet de construire des communautés plurielles. Il discute certains textes de philosophie politique, où semble centrale la question de l’accord (...) comme horizon d’attente des confrontations argumentatives. L’article utilise cette hypothèse pour analyser la diffusion de la dynamique de Leibniz dans sa correspondance avec De Volder. Cette analyse permet de montrer que le dissensus n’est pas un obstacle mais le socle à partir duquel de multiples diffusions sont possibles. (shrink)

Le s jour de Voltaire et Mme Du Ch telet Cirey, depuis le retraite forc e de Voltaire en mai 1734 jusqu' la mort dramatique et douloureuse de Mme Du Ch telet en septembre 1749, fut une p riode merveilleusement f conde, et l'empreinte en fut durable dans la vie intellectuelle de l'Europe. Les contributions rassembl es ici font un tableau de la vie quotidienne Cirey, suivent les deux philosophes dans leurs tudes et leurs voyages, et dessinent les traits de (...) la philosophie newtonienne qu'ils ont cultiv e et r pandue.

En la siguiente exposición se propone un comentario de la obra del filósofo cubano Pablo Guadarrama González, denominada Pensamiento filosófico latinoamericano. Humanismo, método e historia. La perspectiva humanista que es postulada contiene una serie de precisiones que son analizadas en sus implicaciones teóricas y prácticas. Asimismo, se extiende su estudio de las ideas filosóficas a distintos momentos del desarrollo particular seguido en América Latina, al igual que está acompañada esta tarea historiográfica de consideraciones metodológicas que resultan significativas. Desde el conjunto (...) de temas planteados por el autor se retoman sus aportes en relación a debates que se inscriben en el cruce disciplinario de la filosofía y la historia de las ideas, que se ubican inicialmente en el contexto latinoamericano pero aspiran a una proyección con alcances universales. We comment the Cuban philosopher Pablo Guadarrama González’s Latin American philosophical thinking. Humanism, method and history. The humanistic perspective posited therein contains some assumptions that we analyze in their theoretical and practical implications. Furthermore, we extend his study of philosophical ideas to different moments of Latin America’s particular development, being this historiographic task accompanied by significant methodological considerations. Of all the themes posed by this author, we take his contributions to the debates raised in the interdisciplinary intersection of philosophy and the history of ideas, initially located in a Latin American context but with universal projection.

Resumen Este artículo analiza si en la teoría de los cuatro ethe de la modernidad capitalista, desarrollada por Bolívar Echeverría, no está contenida una debilidad de principio. Se trata de saber si para arribar a sus más altas aportaciones, esta teoría no termina pagando un precio que debiera dar que pensar. ¿Acaso renuncia a la crítica de la ideología, por lo menos en la radicalidad realizada por los autores de la Teoría crítica, inspirados en este punto originalmente por Georg Lukács?This (...) article is analyzing if in the theory of the four ethe of capitalist modernity, developed by Bolívar Echeverría, isn’t included a basic weakness. It is about understanding if for to arrive to its highest contributions, this theory is not paying a too high prize. Does it possibly renounce to the critique of ideology, at least in the radicality fulfilled by the authors of Critical theory, inspired in this point originally by Georg Lukács? (shrink)

De todos os aspectos do comportamento não-verbal, a face é sem dúvida uma das mais ricas e importantes fontes de informação sobre o estado inter- no do outro. Mas expressões faciais são raramente percebidas de forma isolada. Ao contrário, são tipicamente inseridas em contextos sociais ricos e dinâmicos, que incluem gestos e posturas corporais, conhecimento situacional, etc. Com base nessas observações, podemos nos perguntar se o contexto no qual uma expressão é percebida pode influenciar a percepção de emoções nesta expressão. (...) No caso de uma resposta afirmativa, de que modo se daria essa influência contextual, e quais seriam os seus limites? O propósito desse artigo é explorar algumas possibilidades sobre o papel do contexto na percepção de emoções, desde a teoria das emoções básicas, que defende que categorias discretas de emoções podem ser lidas diretamente da face de forma invariável, a abordagens mais contemporâneas, que atribuem um papel constitutivo para o contexto na percepção de emoções. Embora o debate esteja longe de ser resolvido, as conclusões deste artigo apontam para um novo modo de se pensar sobre fenômenos emocionais, onde a díade de interação torna-se a unidade básica de análise, e onde emoções são concebidas como propriedades emergentes de relações em contextos particulares de interação social.
