Leibniz’s claim that possibles strive towards existence has led to diverging interpretations. According to the metaphorical interpretation, only the divine will is causally efficacious in bringing possibles into exisence. According to the literal interpretation, God endows possibles with causal powers of their own. The present article suggests a solution to this interpretative impass by suggesting that the doctrine of the striving possibles can be understood as a consequence of Leibniz’s early cognitivist theory of volition. According to this theory, thinking the degree of goodness of something is identical with wanting it to this degree. Arguably, this analysis of volition is relevant not only for Leibniz’s early analysis of the human mind but also for his early analysis of the divine mind.

ABSTRACT: This article explores Wittgenstein's little known remarks on colour from his notebooks of the early 1930s. It emphasizes the importance of the notion of logical multiplicity contained in these remarks. The notion of logical multiplicity indicates that Wittgenstein, as in the years of the Tractatus, is committed to a theory of logical space in which every colour is embedded. However, logical multiplicities in his remarks of the early 1930s do not depend on an apparatus of simple objects, states of affairs, and elementary propositions. I suggest that, in this period, the logical multiplicity of colour space is a matter of how we see colours.RÉSUMÉ: Cet article examine les remarques trap peu connues de Wittgenstein sur les couleurs dans ses cahiers du début des années 1930. Je souligne l'importance qu'y prend la notion de multiplicité logique, qui est le signe que Wittgenstein souscrivait alors, tout autant que dans les années du Tractatus, à une théorie de l'espace logique propre à chaque couleur. Dans ces remarques du début des années 1930, les multiplicités logiques ne dépendent toutefois pas du dispositif conceptuel constitué par les objets simples, les états de choses et les propositions élémentaires. Mon propos est de montrer que, dans cétte periode, la multiplicité logique de l'espace chromatique est relative à la manière dont nous voyons les couleurs.

Sixteenth century pharmacology was still very much under the influence of a distinction going back to ancient medicine: the distinction between effects of medicaments that were taken to be explainable by the elementary qualities, their mutual modification in mixture, and the combination of these modified elementary qualities on the one hand, and the effects of medicaments that were taken not to be explicable in this manner.1 Galen coined the expression that a medicament of the latter kind possesses the capacity of acting "by its whole substance,"2 and the question of how actions of the whole substance could be explicated gave rise to heated controversies in early modern pharmacology. Did Galen just...

Neuere Interpretationen von Leibniz' Notizen zur Metaphysik aus den Jahren 1675-1676 tendieren dazu, diese Texte im Licht eines spinozistischen Substanz-Monismus zu lesen. Obwohl es für eine solche Interpretation überzeugende Anhaltspunkte gibt, vertritt Leibniz jedoch in denselben Texten auch einen Substanzen-Pluralismus in Bezug auf geistige Substanzen. Substanz-Monismus und Substanzen-Pluralismus scheinen miteinander vereinbar zu sein, weil für Leibniz, ähnlich wie für Descartes in den Principia philosophiae, der Terminus ‚Substanz‛ nicht in univoker Weise von Gott und von Gegenständen in der Welt ausgesagt werden kann.

Contemporary accounts of knowing one’s own mental states can be instructively supplemented by early modern accounts that understand self-knowledge as an important factor for flourishing human life. This article argues that in the early modern French moralists, one finds diverging conceptions of how knowing one’s own personal qualities could constitute a kind of human excellence: François de la Rochefoucauld argues that the value of knowing one’s own character faults could contribute to an attitude of self-acceptance that liberates one from the effort of deceiving oneself and others. Madeleine de Scudéry argues that knowing one’s own character faults could be an incentive for self-cultivation that leads to the development of character traits that are naturally good. Anne-Thérèse de Lambert concurs with Scudéry’s insight and develops it further. According to Lambert, self-knowledge is crucial for developing character traits that give rise to the natural right of bei...

Between 1707 and 1708, Georg Ernst Stahl presented his medical doctrine under the title Theoria Medica vera. Leibniz immediately questioned certain points in Stahl's doctrine. He made two principal points: the first dealt with three general questions on the logical and metaphysical foundations of science; the second focused on certain specific statements made by Stahl in his treatises. The controversy between Stahl and Leibniz can be used as a prism through which the debate within the République des Lettres about the living body can be analyzed. Leibniz's philosophy is built as a diachronic and synchronic dialogue, which aims at building an encyclopaedia, that makes sense of reality. What is at stake in the controversy is a definition of the organism as mixed and living. Therefore, the questions this essay deals with are: Why, and how, does Leibniz use the method of controversy to define his object, the organism, as a mixed and living body? I submit that the use of this method reflects a search for a touchstone for assessing two theses concerning the same object. That is to say, through their controversy, Leibniz and Stahl test their two incompatible philosophies of nature: the controversy should help to establish which philosophy of nature corresponds most adequately to the contemporary state of knowledge in medicine and chemistry.

ArgumentThis article examines the conception of elements in the natural philosophy of Nicolaus Taurellus (1547–1606) and explores the theological motivation that stands behind this conception. By some of his early modern readers, Taurellus may have been understood as a proponent of material atoms. By contrast, I argue that considerations concerning the substantiality of the ultimate constituents of composites led Taurellus to an immaterialist ontology, according to which elements are immaterial forms that possess active and passive potencies as well as motion and extension. In Taurellus's view, immaterialism about elements provides support for the theological doctrine of creationex nihilo. As he argues, the ontology of immaterial forms helps to explicate a sense in which creatures are substances, not accidents of the divine substance. In particular, he maintains that immaterial forms stand in suitable relations of ontological dependence to God: creation dependence (since forms would not exist without the divine act of creation), but neither subsistence dependence (since forms continue to exist without continued divine agency) nor activity dependence (since forms are active without requiring divine concurrence).

In an influential article, Gerd Grasshoff has argued for the identification of the objects in Wittgenstein's Tractatus with the ultimate constituents of reality in Heinrich Hertz's Principles of Mechanics. Grasshoff's interpretation is based on two interrelated claims: The specific determination of the objects in the world and the relation among them is the primary theme in Wittgenstein's early philosophy, because it is the primary theme for Hertz. Wittgenstein did not assume the existence of simple objects on purely logical grounds without having specific examples of simple objects in mind, because Hertz did not do this.

Summary This article explores some continuities between Late Aristotelian and Cartesian embryology. In particular, it argues that there is an interesting consilience between some accounts of the role of imagination in trait acquisition in Late Aristotelian and Cartesian embryology. Evidence for this thesis is presented using the extensive biological writings of the Padua-based philosopher and physician, Fortunio Liceti (1577–1657). Like the Cartesian physiologists, Liceti believed that animal souls are material beings and that acts of imagination result in material images that can be transmitted by means of medical spirits to the embryo. Moreover, while the Cartesian embryologists accepted such a view in a quite speculative way, one finds penetrating criticism of imagination theories of trait acquisition in the Late Aristotelian tradition. Evidence for this thesis is presented using the no less extensive biological writings of Liceti's contemporary, Emilio Parisano (1567–1643). In conclusion, the Late Aristotelian tradition itself provides the theoretical tools for excising immaterial formative forces from embryology and at the same time evinces a much more acute sense for the problems inherent in imagination theories of trait acquisition than the Cartesian tradition.

Gabriel Bonnot de Mably takes up the republican commonplace that the desire for esteem is what could motivate the fulfilment of duties of civic virtue. This commonplace, however, has become problematic through the discussion of the problem of human corruption in philosophers such as Blaise Pascal and Nicolas Malebranche. In this article, I will show that Mably takes this problem seriously. However, his critique of Malebranche’s solution to this problem and his critique of the economic reinterpretation of Malebranche’s concept of natural order in the work of Le Mercier de la Rivière motivate his own republican defense of the moral value of the desire for esteem. What makes this defense plausible is his argument that distorted esteem derives from imagination that is distorted, not only as a result of natural factors, but in many cases rather as a result of misguided politics. If some cases of distorted esteem derive from misguided politics, Mably argues, then they can be modified by republican constitution building that modifies the imagination of citizens.

SUMMARYThis article investigates the context of a side line in Leibniz's critique of Locke on maxims. In an enigmatic and little-explored remark, Leibniz objects that Locke has overlooked some legal maxims that fulfil the function of ‘constituting the law’. I propose to read this remark against the background of the divergence between conceptions of legal maxims in the common law tradition and conceptions of legal maxims in the Roman law tradition. In a few remarks, Locke seems to echo the common law emphasis on customs and conventions expressed by legal maxims. According to such a conception, reason would mainly fulfil the function of subsuming particular norms under more general conventional norms. By contrast, Leibniz uses the Roman law idea that some ‘rules of law’ express demands of natural reason and, thereby, express principles constitutive of natural law. This is why he proposes to reform vague and confused ‘brocards’ used by jurists in order to identify sound maxims that provide a natural-law foundation for legal institutions.

In this discussion note, I defend four claims: (1) The interpretation of Leibniz's theory of simple substances as a philosophy of panpsychism has no direct support from Leibniz's texts. (2) According to Leibniz there is a perfect continuity between perceptions of different degrees of distinctness. (3) Nevertheless, due to the reflective structure of sensation, there is a discontinuity between the perceptions of bare simple substances and sensations, which are characteristic of souls. (4) Finally, Leibniz's principle of continuity leaves room for this kind of discontinuity between different kinds of simple substances.

Julius Caesar Scaliger was a natural philosopher and literary theorist whose work was widely discussed throughout the second half of the sixteenth and the first half of the seventeenth centuries. After this period, it fell into oblivion, only to be rediscovered during the last three decades or so. His natural philosophy has triggered a series of specialized studies on particular aspects of his thought, especially those aspects that were influential in the development of early modern corpuscularianism. Sakamoto's book goes considerably beyond such fragmentary approaches and presents central strands of Scaliger's most important work in natural philosophy, a thousand-page critique of Girolamo Cardano's De...

Theorien von Gerechtigkeit als einer ethischen Tugend spielen eine große Rolle in der protestantischen Ethik vor dem Dreißigjährigen Krieg. Eines der hervorstechenden Merkmale dieser Theorien ist ihr eklektischer Charakter: Sie verbinden Elemente aus verschiedenen Traditionen der antiken Tugendethik, vor allem der platonischen, aristotelischen und stoischen. Die Gerechtigkeitstheorien von protestantischen Philosophen wie Rudolph Goclenius, Clemens Timpler und Bartholomäus Keckermann illustrieren gut dokumentierte Merkmale des frühneuzeitlichen Eklektizismus wie die Rolle der Reinterpretation von ausgewählten Lehrstücken und die konziliatorische Strategie, scheinbare Widersprüche zwischen verschiedenen Traditionen aufzulösen. Darüber hinaus illustrieren sie aber auch ein weniger gut dokumentiertes Merkmal des frühneuzeitlichen Eklektizismus, nämlich seine Funktion als philosophische Problemlösungsstrategie. Dieser Artikel versucht zu zeigen, wie Goclenius, Timpler und Keckermann einerseits Elemente aus den platonischen (und stoischen) Traditionen nutzen, um diagnostizierte Probleme in der aristotelischen Tradition zu beheben und andererseits Elemente aus der aristotelischen Tradition verwenden, um Probleme in der platonischen Tradition zu lösen.

This paper investigates the relationship between some corpuscularian and Aristotelian strands that run through the thought of the sixteenth-century philosopher and physician Julius Caesar Scaliger. Scaliger often uses the concepts of corpuscles, pores, and vacuum. At the same time, he also describes mixture as involving the fusion of particles into a continuous body. The paper explores how Scaliger’s combination of corpuscularian and non-corpuscularian views is shaped, in substantial aspects, by his response to the views on corpuscles and the vacuum in the work of his contemporary, Girolamo Fracastoro. Fracastoro frequently appears in Scaliger’s work as an opponent against whom numerous objections are directed. However, if one follows up Scaliger’s references, it soon becomes clear that Scaliger also shares some of Fracastoro’s views. Like Scaliger, Fracastoro suggests corpuscularian explanations of phenomena such as water rising in lime while at the same time ascribing some non-corpuscularian properties to his natural minima. Like Scaliger, Fracastoro maintains that there is no vacuum devoid of bodies since places cannot exist independently of bodies (although their opinions diverge regarding how exactly the relevant dependency relation might be explicated). Finally, like Scaliger, Fracastoro connects a continuum view of mixture with a theory of natural minima.

In den Elementa juris naturalis behauptet Leibniz, dass es rational ist zu präsumieren, dass eine gegebene Handlung gerecht ist. Diese Behauptung scheint in Widerspruch zu seiner Auffassung zu stehen, dass das, was präsumiert wird, einfacher ist als sein Gegenteil. Nach Leibniz ist einfacher, was weniger Voraussetzungen hat als etwas anderes, wobei er zwischen logischen und ontologischen Voraussetzungen unterscheidet. Dieser Diskussionsbeitrag versucht zu zeigen, dass Voraussetzungen auf der ontologischen Ebene eine oft übersehene Rolle für die Präsumption der Gerechtigkeit einer Handlung spielen und dass sich der scheinbare Widerspruch auf dieser Ebene auflösen lässt. Nach Leibniz ist eine gerechte Handlung eine spezielle Art von Möglichkeit: eine Handlung, die für eine moralische Person möglich ist. Ihm zufolge hat aber ein mögliches Ereignis weniger ontologische Voraussetzungen als ein unmögliches Ereignis, weil die ontologischen Voraussetzungen eines möglichen Ereignisses ein Teil der Voraussetzungen eines unmöglichen Ereignisses sind. Die Präsumption zu Gunsten der Gerechtigkeit einer Handlung lässt sich als Spezialfall der Präsumption zu Gunsten der Möglichkeit eines Ereignisses auffassen.

ArgumentThe sixteenth-century physician and philosopher Julius Caesar Scaliger suggests that in particular cases plants can come into being that belong to a plant species that did not exist before. At the same time, he holds that God could not have created a more perfect world. However, does the occurrence of new species not imply that the world was not the best possible world from the beginning? In this article, I explore a set of metaphysical ideas that could provide Scaliger with the means of solving this problem: His version of the notion of a plurality of substantial forms in every living being, and his version of the notion of the ordained divine power. As it turns out, Scaliger analyzes the generation of new species in terms of a development of subordinate substantial forms into dominant substantial forms. Thereby, previously existing essences of plant parts become essences of plants. These plants, thus, possess essences that no previously existing plant possessed and, in this sense, belong to a new species. In this way, Scaliger avoids positing the occurrence of new essences, thus saving the best possible world thesis. Moreover, he believes that all substantial forms stand in a relationship of mutual existential dependence by means of which God safeguards the persistence and unity of the world. This is why the agency of subordinate forms turned dominant can be understood as an expression of the ordained power of God.

Robert M. Adams claims that Leibniz’s rehabilitation of the doctrine of incomplete entities is the most sustained effort to integrate a theory of corporeal substances into the theory of simple substances. I discuss alternative interpretations of the theory of incomplete entities suggested by Marleen Rozemond and Pauline Phemister. Against Rozemond, I argue that the scholastic doctrine of incomplete entities is not dependent on a hylomorphic analysis of corporeal substances, and therefore can be adapted by Leibniz. Against Phemister, I claim that Leibniz did not reduce the passivity of corporeal substances to modifications of passive aspects of simple substances. Against Adams, I argue that Leibniz’s theory of the incompleteness of the mind cannot be understood adequately without understanding the reasons for his assertion that matter is incomplete without minds. Composite substances are seen as requisites for the reality of the material world, and therefore cannot be eliminated from Leibniz’s metaphysics.

According to the Cambridge Platonist Henry More, individual spirits--the souls of humans and non-human animals--are extended but cannot be physically divided. His contemporaries and recent commentators have charged that More has never given an explication of the grounds on which the indivisibility of spirits is based. In this article, I suggest that exploring the usage that More makes of the analogy between spirits and light could go some way towards providing such an explication. More compares the relation between spirit and matter to the relation that, according to Aristotelian theories of light, holds between?intentional species? and matter. I will argue that the purpose of his comparison is to highlight that both intentional species and spirits are existentially independent from matter. The existential independence of intentional species from matter expresses itself in the fact that light is not moved through the motion of the illuminated body. The existential independence of spirits from matter expresses itself in the fact that when a body that is coextensive with a spirit is divided, the spirit is not thereby divided but rather contracts into the remaining living organism.
