Leibniz: Philosophy of Action

As far as treatments of causation are concerned, the pre-Kantian 18th century German context has long been dismissed as a period of uniform and unrepentant Leibnizian dogmatism. While there is no question that discussions of issues relating to causation in this period inevitably took Leibniz as their point of departure, it is certainly not the case that the resulting positions were in most cases dogmatically, or in some cases even recognizably, Leibnizian. Instead, German theorists explored a range of positions regarding (...) the nature of causal powers, the appropriate systems to explain the observed agreement between the states of substances, and the ground of free actions, or so I will argue in this chapter. Focusing on these three issues, I will here sketch the development of the debates relating to causation and trace the evolution of positions among the philosophers within the so-called Leibnizian-Wolffian philosophy as well as among its many opponents.

Our focus in this article concerns Leibniz’s views on evil. Our goal is to examine which are the consequences of his conception of moral agency for the moral psychology of the genuinely evil person. For Leibniz, moral failure is an epistemic error since it involves some false practical judgement. Moral maxims may be represented in blind or symbolic cognitions, but then moral agents can misrepresent the evil consequences of their behaviour. Finally, we discuss Leibniz’s view on habits that may help (...) virtuous persons strive for perfection but also enable evil persons to continue sinning. (shrink)

The advance of mechanism in science and philosophy in the 17th century created a great interest to machines or automata. Leibniz was no exception - in an early memoir Drôle de pensée he wrote admiringly about a machine that could walk on water, exhibited in Paris. The idea of automatic processing in general had a large role in his thought, as can be seen, for example, in his invention of the binary code and the so-called Calculemus!-model for solving controversies. In (...) metaphysics, the idea of an automata was expressed most clearly in the 1695 article New System of the Nature of Substances and their Communication, and the ensuing correspondence with, among others, Foucher, Bayle, Lamy, Jaquelot and Masham. In the article Leibniz discusses the soul as a spiritual machine in the context of pre-established harmony, arguing that God can "give to a substance at the outset a nature or internal force which could produce in it an orderly way (as in spiritual or formal automaton; but a free one, in the case of a substance which is endowed with a share of reason) everything that is going to happen to it, that is to say, all the appearances or expressions it is going to have, and all without the help of any created thing." The basic idea of Leibniz's spiritual machine is that the soul or entelechy is an autonomous and spontaneous unity, consisting of internal active force and producing its own perceptions (both confused and distinct). It is a self-moving machine, driven by its perceptions and appetites, but it follows (without being conscious of it) a lawful series or programme created by God. The entelechy remains the same despite undergoing an infinite number of changes. To Foucher he explained that each state of the individual substance is a consequence of its preceding one, "as if there were only God and the substance in the world". Despite this, the spiritual machine is related not only to God, but through the pre-established harmony to bodies or natural machines. However, as it is not dependent on them, the spiritual machine is superiot to natural machines. In this paper I concentrate on three moral themes related to the spiritual machine: moral deliberation, moral identity and the goal of moral action. All these themes are more or less implicit in the New System, but are discussed in more detail in the ensuing correspondence after the publication of the article. Finally, the themes are given an extended discussion especially in the second book of New Essays on Human Understanding (1704, published 1765), written partly at the same time as some of the correspondence and unpublished related material. I will first give an overview of Leibniz's position concerning the spiritual machine or automaton in the New System and then go on to explore the three moral themes one by one, as they feature in the subsequent correspondence and in the New Essays. I will show that the three topics are essential to the function of the spiritual machine – to Sophie Charlotte Leibniz wrote: "...let us say that everything in bodies happens mechanically, or in accordance with laws of motion, and that everything in the soul happens morally, or in accordance with perceived good or evil." There are many texts that anticipate the views in the New System (notably the unpublished memoir De Affectibus of 1679) and Leibniz continued to discuss its themes later on (in addition to correpondence, for example, in Theodicy of 1710 and Monadology and Principles of Nature and Grace of 1714). Here I focus on the short-term development of Leibniz's views on the topic (around 1695-1705), but I argue that his basic view of the spiritual machine did not change much after finishing the dialogue with Locke in 1704.

G. W. Leibniz developed a new model for rational decision-making which is suited to complicated decisions, where goods do not rule each other out, but compete with each other. In such cases the deliberator has to consider all of the goods and pick the ones that contribute most to the desired goal which in Leibniz’s system is ultimately the advancement of universal perfection. The inclinations to particular goods can be seen as vectors leading to different directions much like forces in (...) Leibniz’s dynamics. The vectorial model of rational decision-making is related to Leibniz’s work with metaphysical physics and the calculus of variations and is a heuristic tool which helps in finding reasonable combinations – in ideal cases optimums - between competing goods. By applying the model, the decision-maker can map and compare outcomes of combinations of goods in question and practice a kind of pseudo-mechanical arithmetic of reasons. A central feature of the model is the possibility to employ geometrical figures to help the conceptualization. In this paper I present the vectorial model, examine its applications in practical cases from political theory, jurisprudence and ethics Leibniz presented, and compare the model to recent theories of acting under uncertainty, such as bounded rationality and optimizing under constraints.

This paper locates a source of contingency for Leibniz in the fact that God can do otherwise, absolutely speaking. This interpretative line has been previously thought to be a dead-end because it appears inconsistent with Leibniz’s own conception of God, as the ens perfectissimum, or the most perfect being (Adams, 1994). This paper points out that the best argument on offer which seeks to demonstrate this inconsistency fails. The paper then argues that the supposition that God does otherwise implies for (...) Leibniz (at least) that God would not be praiseworthy, which is an absurd implication—or a violation of the principle of sufficient reason (PSR)—but that this is not, strictly speaking, an inconsistency—or a violation of the principle of contradiction (POC). While praiseworthiness is a perfection—and is compossible with God’s other perfections—and so God must instantiate it, this paper argues that, given the nature of praiseworthiness for Leibniz, it in fact makes sense to say that praiseworthiness is merely a contingent perfection of God. (shrink)

I argue for a novel interpretation of Leibniz’s conception of the kind of contingency that matters for freedom, which I label ‘agential contingency.’ In brief, an agent is free to the extent that she determines herself to do what she judges to be the best of several considered options that she could have brought about had she concluded that these options were best. I use this novel interpretation to make sense of Leibniz’s doctrine that the reasons that explain free actions (...) are merely inclining and not necessitating. (shrink)

Gottfried Wilhelm Leibniz endorses a version of the guise of the good thesis: he holds that whenever we do something intentionally, we do it because it seems good to us. This paper explores Leibniz...

On the standard interpretation, Samuel Clarke and Gottfried Wilhelm Leibniz endorse fundamentally different theories of free will. Clarke is typically interpreted as a libertarian who holds that freedom requires indeterminism. Leibniz, in contrast, is typically interpreted as a compatibilist who holds that free actions can be determined. This chapter challenges the standard interpretation and argues that Clarke and Leibniz agree almost completely about free will. Both require free actions to be instances of agent causation, and both view freedom as compatible (...) with moral necessity or the determination by motives, reasons, or final causes. Hence, both Leibniz and Clarke should be interpreted as proponents of compatibilism. (shrink)

First published in 1999, this volume considers the 17th century philosopher Leibniz and his views on Freedom and Determinism, aiming to show that his solution is in many respects superior to those of Aquinias and Molina. The author thoroughly explores Leibniz in the light of Aquinas and Molina, first examining their positions on freedom and determinism, followed by Leibniz on freedom, contingency and determinism, the denial of freedom of pure indifference, freedom and divine foreknowledge and major interpretations of his philosophy.

This article examines the rift in Leibniz’s conception of determinism after being rebuffed by the Parisian theologian Antoine Arnauld in their correspondence of 1686. As, in addition, his study of surds infracted his confidence in the “complete concept,” Leibniz embarked on a new, dynamic doctrine of substance or “law of the series.” In the literature, this strategy has been widely understood as “tweaking” the system to allow some self-assertion of free will. But as this article will show, it amounts to (...) a revolutionary conception that culminates in the unmasking of determinism as an insupportable, indeed incoherent doctrine. As all forms of determinism are profoundly entangled with human self-perception, the Leibnizian Kehre invites us to a new engagement with human freedom and autonomy and the disentanglement from a philosophical position for which neither a metaphysical nor an empirical proof can be given.

Resumen: El presente trabajo pretende analizar algunos de los postulados principales de la ontología vitalista de Leibniz, en especial su noción de máquina natural y su propuesta monadológica, con la finalidad de demostrar la viabilidad en su pensamiento de una teoría de la acción. Se divide en tres partes: la primera examina la estructura compleja de las máquinas naturales, a partir de la cual se puede observar una composición dual de la acción; a partir de esto, la segunda parte distingue (...) tres tipos de mónadas con la intención de perfilar la posibilidad de una agencia racional; y, finalmente, la tercera parte ofrece algunas conclusiones relevantes para su teoría de la acción, como el papel de la percepción en el proceso de elección y el intelectualismo leibniziano, entre otros.: This paper aims to analyze key postulates of Leibniz’s vitalist ontology, with a special emphasis on his conception of a natural machine and his monadological proposal. It is divided into three sections: first I analyze the complex structure of natural machines, from which a twofold composition of action can be reckoned; hence, the second section identifies three kinds of monads, with the purpose of devising the possibility of rational agency; finally, the third section draws some relevant conclusions for Leibniz’s account of action, as the place of perception in the process of choice and Leibnizian intellectualism, among others.

This is a response to Donald Rutherford's review of Jorati, Leibniz on Causation and Agency. The review is published in Leibniz Review 27 (2017), 183-197.

This book presents a comprehensive examination of Gottfried Leibniz's views on the nature of agents and their actions. Julia Jorati offers a fresh look at controversial topics including Leibniz's doctrines of teleology, the causation of spontaneous changes within substances, divine concurrence, freedom, and contingency, and also discusses widely neglected issues such as his theories of moral responsibility, control, attributability, and compulsion. Rather than focusing exclusively on human agency, she explores the activities of non-rational substances and the differences between distinctive types (...) of actions, showing how the will, appetitions, and teleology are key to Leibniz's discussions of agency. Her book reveals that Leibniz has a nuanced and compelling philosophy of action which has relevance for present-day discussions of agency. It will be of interest to scholars and students of early modern philosophy as well as to metaphysicians and philosophers of action. (shrink)

Leibniz was obsessed with freedom. He turns to this topic again and again throughout his long career. And what he has to say about freedom is much more resourceful and inventive than typically acknowledged. While building on medieval theories—for instance by describing freedom in terms of the relation between the agent’s will and intellect—he also adds radically new elements and even anticipates some views that are popular today. The combination of theses about free will that Leibniz endorses in his mature (...) writings is unusual and may at first appear inconsistent: (a) he claims that some of our actions are free, (b) he links free agency closely to agent causation and in fact appears to deny that there is event causation; (c) he accepts a form of determinism. In other words, Leibniz endorses what we can describe as an agent-causal compatibilist theory of freedom. The three theses may seem to be in tension not only because proponents of agent causation views are typically incompatibilists, but also because determinism is often defined in a way that presupposes event causation. As we will see soon, however, the tension is merely apparent. Leibniz’s version of agent-causal compatibilism is perfectly coherent and has some unique advantages over rival accounts. (shrink)

Leibniz is an eclectic and ecumenical philosopher. He often worked out philosophical positions that reconciled seemingly opposed theoretical systems and chastised people for rejecting certain views too quickly. In this paper, I describe one episode of Leibnizian reconciliation. My target is the phenomenon of deliberation. Traditionally, philosophers have offered two different accounts of deliberation based on two different accounts of the compatibility of freedom and determinism. Leibniz, I argue, cannot accept either account because of his broader theoretical commitments. This leads (...) Leibniz to formulate an interesting account of deliberation that adopts certain elements from each account while excising the untoward aspects of each one. I outline the various mechanisms involved in deliberation on Leibniz’s view and show how deliberation fits into a broader theory of free action. I close with an assessment of whether Leibniz in fact succeeds in offering an account of deliberation that is distinct from the traditional positions. (shrink)

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. (shrink)

spontaneity is a key concept of freedom in Kant and Leibniz philosophy. Leibniz defends spontaneity as a necessary condition for freedom, and defines it generally in terms of the absence of constraint. According to Leibniz, every substance is sole cause of all of its own states thus every change that occurs in it occurs spontaneously. Two type of spontaneity in Leibniz is determined by his commentators monadic spontaneity and agent spontaneity. Kant, from the Leibnizian tradition took the idea that spontaneity (...) is not only the inner principle of action but also characterizes the subject as a thinking substance. But Kant explains the spontaneity by introducing two kinds of spontaneity, relative and absolute. The understanding is relatively spontaneous when it refers to an object of experience that must be subsumed under categories. Reason is absolutely spontaneous in legislating, in following and in incorporating moral law but is relatively spontaneous when it is affected by the empirical and heterogeneous elements of sensible nature. the power of judgement is relatively spontaneous when it can refer only to the object of an actual experience. (shrink)

Locke and Leibniz are often classified as proponents of compatibilist theories of human freedom, since both maintain that freedom is consistent with determinism and that the difference between being and not being free turns on how one is determined. However, we will argue in this paper that their versions of compatibilism are essentially different and that they have significantly distinct commitments to compatibilism. To this end, we will first analyze the definitions and examples for freedom and necessity that Locke and (...) Leibniz present in sections 8-13 of chapter 21 of the Essay on Human Understanding and the Nouveaux essais respectively, and then conjecture how Locke and Leibniz would have continued the discussion, if they had had the opportunity to engage in an exchange of opinions. In this way, we believe, one will be in a position to understand why Leibniz thinks that Locke’s discussion of freedom “est un des plus prolixes et des plus subtils de son ouvrage.”. (shrink)

it is one of the central commitments of Leibniz’s mature metaphysics that all substances or monads possess perfect spontaneity, that is, that all states of a given monad originate within it.1 Created monads do not truly interact with each other, for Leibniz. Instead, each one produces all of its states single-handedly, requiring only God’s ordinary concurrence. Several commentators have pointed out that implicit in Leibniz’s view is a distinction between different types of spontaneity: a general type of spontaneity that all (...) monads have perfectly and at all times, and a narrower type of spontaneity that monads possess in only some of their actions. Some commentators make a similar case for two types of teleology:.. (shrink)

The purpose of this paper is to explain and discuss Leibniz’s main objections to the Molinist-Suárezian voluntarist (libertarian) conception of freedom, i.e., the conception involving the supposition of “freedom of indifference” of the will to make contrary choices in exactly the same circumstances. Leibniz’s main objections to the voluntarist conception are the following: (i) it violates the Principle of Sufficient Reason; (ii) it is based on a mistaken picture of the nature of the will.

In this paper I will discuss the doctrine of substance which emerges from Leibniz’s unpublished early memoir De affectibus of 1679. The memoir marks a new stage in Leibniz’s views of the mind. The motivation for this change can be found in Leibniz’s rejection of the Cartesian theory of passion and action in the 1670s. His early Aristotelianism and some features of Cartesianism persisted to which Leibniz added influences from Hobbes and Spinoza. His nascent dynamical concept of substance is seemingly (...) a combination of old and fresh influences, representing a characteristically eclectic approach, but I will argue that the influence of Hobbes is especially important in the memoir. To do that, I will examine Leibniz’s development in the 1670s up to the De affectibus and consider the nature of affects in the memoir, especially the first affect which starts the thought sequence. This first affect of pleasure or pain is the key to Leibniz’s theory of active substances and in this way to the whole of Leibniz’s moral psychology and ethical metaphysics. (shrink)

Leibniz seeks to establish the tenability of faith and reason in his moral philosophy through a tripod of thought, consisting of 1) fundamental human goodness; 2) human error in judgment; and 3) that God is just. A difficulty arises concerning how God can justly punish human beings if they always will what is Good. By considering akrasia, which occurs when error is committed despite its clear nonconformity with the Good, and examining the Leibnizian concept of “judgment,” Leibniz’s tripod can be (...) upheld. (shrink)

Most interpreters think that for Leibniz, teleology is goodness-directedness. Explaining a monadic action teleologically, according to them, simply means explaining it in terms of the goodness of the state at which the agent aims. On some interpretations, the goodness at issue is always apparent goodness: an action is end-directed iff it aims at what appears good to the agent. On other interpretations, the goodness at issue is only sometimes apparent goodness and at other times merely objective goodness: some actions do (...) not aim at what appears good to the agent, but merely at what is objectively good—that is, at what God knows to be good—and that is sufficient for teleology. My paper, on the other hand, argues that both of these interpretations are mistaken. Monadic teleology, I contend, does not have to consist in striving for the good; neither goodness nor God is required to make monadic actions teleological. (shrink)

This article is an attempt to investigate a classic problem associated with the human action that can be extracted from the Leibnizian texts about the weakness of will, an issue emblematically briefed by Ovide: “I see clearly which [way] is better, and I know it is right, yet I follow the way that is worse”. The author of the Theodicy seems to suggest a way to understand the phenomenon of akrasia. A good source for this research is his work New (...) Essays on Human Understanding, in which he directly debates thesis of the book An Essay Concerning Human Understanding by Locke. In Leibnizian text, one of the concepts discussed is the uneasiness. Locke believes that the fundamental basis for human actions would be to prevent the uneasiness caused by the feeling of missing something. Leibniz not completely refutes the idea of the English philosopher, however looks for improving it by introducing “the perceptions which are not apperceived”. In Leibnizian philosophy the problem of weakness of will may be linked to a region that the agent does not know directly but which is fundamental to any action, even for the so-called rational.

Chapter 20 of book II of John Locke’s An Essay Concerning Human Understanding, titled ‘Of Modes of Pleasure and Pain’ is the most extensive discussion of emotions available in Locke’s corpus. Likewise, Nouveaux essais sur l’entedement humain, II, xx, together with the following chapter xxi remains the chief source of Leibniz’s views of emotions. They offer a very interesting and captivating discussion of moral philosophy and good life. The chapter provides also a great platform to study Leibniz’s argumentative techniques and (...) the differences between the philosophers in general. Locke strives to explain the emotions with a single, unifying notion of uneasiness while Leibniz’s view of the mind is much more complex and he finds more unique ways of explaining different emotions. My paper focuses on Leibniz’s critique of Lockean uneasiness as an explanans for emotions. He views uneasiness as a unavoidable part of all our mental states and therefore it is not sufficient to explain passions or moral wrong-doing of men. I will discuss such passions as love, joy, sorrow, hope, fear, despair, anger, envy and shame and consider Locke’s possible response to Leibniz’s critique. (shrink)

Leibniz holds that creatures require divine concurrence for all their actions, and that this concurrence is 'special,' that is, directed at the particular qualities of each action. This gives rise to two potential problems. The first is the problem of explaining why special concurrence does not make God a co-author of creaturely actions. Second, divine concurrence may seem incompatible with the central Leibnizian doctrine that substances must act spontaneously, or independently of other substances. Concurrence, in other words, may appear to (...) jeopardize creaturely substancehood. I argue that Leibniz can solve both of these problems by invoking final and formal causation. The creature is the sole author of its actions because it alone contributes the formal and final cause to these actions. Similarly, because it contributes the formal and final cause, the creature possesses what I call explanatory spontaneity. Leibniz, I contend, considers this type of spontaneity sufficient for substancehood. (shrink)

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)

Artikkelissaan ”The Balance of Reason” Marcelo Dascal on osoittanut, että metafora syiden punnitsemisesta järjen vaa’assa on yleinen Leibnizin kirjoituksissa ja sitä on pidettävä hänen yleisenä järkeilyn metodinaan tilanteissa, joissa ei voida suorittaa täydellistä loogista analyysiä. Keskustelen tässä esitelmässä tuosta metaforasta ja ehdotan Jaakko Hintikan ja Simo Knuuttilan aiempien esityksien pohjalle rakentaen, että käsityksissään ihmisen praktisesta rationaalisuudesta Leibniz sovelsi myös toista melko tuntemattomaksi jäänyttä heuristista päätöksentekomallia, joka liittyy hänen työhönsä luonnonfilosofiassa ja mielenfilosofiassa, ja jota hän sovelsi tapauksissa joissa päätökseen vaikuttavat arvot (...) ovat toisiaan täydentäviä. Tämä moniarvoisuuden huomioon ottava malli edustaa uudenlaista ja modernia ajattelua moraalifilosofian historiassa. (shrink)

In numerous texts Leibniz claimed that while metaphysical necessity is inconsistent with free choice, moral necessity is not. A question naturally arises concerning what Leibniz took moral necessity to be. In a series of recent articles Michael Murray has argued that the concept of moral necessity Leibniz utilized is one developed and deployed by a group of 17th century Spanish Jesuits. This chapter argues that Leibniz's commitment to certain deep metaphysical principles suggests otherwise.

Bien que Leibniz maintienne que l'examination de l'œuvre de William King, De l'origine du mal, « auroit fourni une bonne occasion d'eclaircir plusieurs difficultés » (GP VI, 400) traitées dans la Théodicée, aucun commentateur n'a encore considéré l'appendice de la Théodicée qui traite du livre de King. Dans cet éssai, je cherche à combler cette lacune. Je commence par présenter le problème de la liberté exploité par Bayle dans le Dictionnaire historique et critique afin de monter l'irrationalité de la foi, (...) et j'esquisse la conception de la liberté présentée dans la Théodicée. Dans la seconde partie de l'éssai, je présente la conception de la liberté défendue par King, avant d'examiner, dans la troisième partie de l'éssai, la critique Leibnizienne de cette conception de la liberté. Dans la dernière partie de l'éssai, j'explique comment ce traitement de l'œuvre de King renforce les arguments de la Théodicée. (shrink)

Leibniz frequently argued that reasons are to be weighed against each other as in a pair of scales, as Professor Marcelo Dascal has shown in his article "The Balance of Reason." In this kind of weighing it is not necessary to reach demonstrative certainty – one need only judge whether the reasons weigh more on behalf of one or the other option However, a different kind of account about rational decision-making can be found in some of Leibniz's writings. In his (...) article "Was Leibniz's Deity an Akrates?" Professor Jaakko Hintikka has argued that Leibniz developed a new vectorial model for rational decisions which is better suited to complicated decisions, where values are complementary to each other. This model, related closely to his work in metaphysics and the philosophy of mind, is a heuristic device which helps in finding rational combinations - and in an ideal case an optimum - between plural inclinations to the good. I shall argue that Leibniz applies more or less implicitly both of these models in his practical rationality. In simple situations he applied the pair of scales model and in more complicated situations he applied the vectorial model. (shrink)

In this paper I argue that the hoary theological doctrine of divine concurrence poses no deep threat to Leibniz’s views on theodicy and creaturely activity even as those views have been traditionally understood. The first three sections examine respectively Leibniz’s views on creation, conservation and concurrence, with an eye towards showing their sys­tematic compatibility with Leibniz’s theodicy and metaphysics. The fourth section takes up remaining worries arising from the bridging principle that conservation is a continued or continuous creation, and argues (...) that they can be allayed once two readings of the prin­ciple are distinguished. What emerges from the discussion as a whole is, I hope, a clearer picture of Leibniz’s views on the nature of monadic causation, his understanding of the relationship between divine and creaturely activity, and his position with respect to later medieval and early modern debates over secondary causation.

In this study I discuss G. W. Leibniz's (1646-1716) views on rational decision-making from the standpoint of both God and man. The Divine decision takes place within creation, as God freely chooses the best from an infinite number of possible worlds. While God's choice is based on absolutely certain knowledge, human decisions on practical matters are mostly based on uncertain knowledge. However, in many respects they could be regarded as analogous in more complicated situations. In addition to giving an overview (...) of the divine decision-making and discussing critically the criteria God favours in his choice, I provide an account of Leibniz's views on human deliberation, which includes some new ideas. One of these concerns is the importance of estimating probabilities – in making decisions one estimates both the goodness of the act itself and its consequences as far as the desired good is concerned. Another idea is related to the plurality of goods in complicated decisions and the competition this may provoke. Thirdly, heuristic models are used to sketch situations under deliberation in order to help in making the decision. Combining the views of Marcelo Dascal, Jaakko Hintikka and Simo Knuuttila, I argue that Leibniz applied two kinds of models of rational decision-making to practical controversies, often without explicating the details. The more simple, traditional pair of scales model is best suited to cases in which one has to decide for or against some option, or to distribute goods among parties and strive for a compromise. What may be of more help in more complicated deliberations is the novel vectorial model, which is an instance of the general mathematical doctrine of the calculus of variations. To illustrate this distinction, I discuss some cases in which he apparently applied these models in different kinds of situation. These examples support the view that the models had a systematic value in his theory of practical rationality. (shrink)

: In this paper, I investigate Leibniz's conception of final causation. I focus especially on the role that Leibnizian final causes play in intentional action, and I argue that for Leibniz, final causes are a species of efficient causation. It is the intentional nature of final causation that distinguishes it from mechanical efficient causation. I conclude by highlighting some of the implications of Leibniz's conception of final causation for his views on human freedom, and on the unconscious activity of substances.

La notion de mondes possibles chez Leibniz est souvent considérée comme un précurseur des théories contemporaines de la sémantique des mondes possibles. Or, cet article vise à montrer que cette lecture de Leibniz est fondamentalement erronée. Leibniz n'a jamais utilisé la notion de mondes possibles pour établir des conditions de vérité pour des phrases modales, mais le rôle de cette notion est strictement théologique, dans le sens où Leibniz l'emploie uniquement pour rendre compte du choix de Dieu dans la création. (...) Dans un premier temps, nous présentons une critique des tentatives d'interpréter les phrases modales chez Leibniz en termes de monde possibles. Dans un deuxième temps, nous nous proposons de montrer que les mondes possibles fonctionnent comme des raisons du choix divin, et que cette thèse est liée à la conception leibnizienne de la nature de la liberté.

Dieses Werk stellt das Denken zweier Geistesgrößen, Leibnizens und Fichtes sich gegenüber und vergleicht es. Fichte sieht in Leibniz einen Vorläufer und erwähnt ihn mit liebevoller Bewunderung. Fichtes Wissenschaftslehre von 1801/02 wird Leibnizens,,Monadologie" aufgreifen und Leibnizens Gedanken einer prästabilierten Harmonie. Beide Philosophen verstehen sich als Freiheitsapostel, wobei bei Leibniz Gott eine genaue Notion jedes Individuums hat, die Freiheit ein mentaler Akt ist, bei Fichte jedes Individuum ein je bestimmtes Soll hat, das es, Freiheit verwirklichend, im Leben zu erfüllen gilt. Fichte (...) erkennt in Leibniz einen Vorläufer der eigenen Transzendentalphilosophie. Ein Unterschied zwischen den beiden Denkern besteht darin, dass Leibniz stets die Individualität im Auge hat, wo Fichte vom reinen Vernunftwesen ausgeht, dessen individuelle Pathologien ihn nicht interessieren. Beide Philosophen supponieren, dass die Welt ein Ende habe, Leibniz, auf dass das Weltgericht stattfinden könne, Fichte, auf dass in einer neuen Welt nur noch die sittlichen Individuen wiedergeboren werden. Der vorliegende Text versucht auch, den Bogen zu schlagen von der philosophischen Tradition des Abendlandes, und insbesondere von Leibniz, Kant und Fichte zu einer Gotteslehre auf Grund der modernen Physik. Die hochenergetische Urmaße wird gefasst als psychophysische Energeia, die sich - im Leibnizschen Sinne Wissen, Macht und Wollen - aus dem Nichts kontrahiert hat und nun ins All explodiert. In der Kontraktion aus dem ursprünglich Verwobenen hat das Absolute sich vom Nichts, das Gute sich vom Bösen geschieden, entsteht das Übel als privatio boni. (shrink)

The ‘middle knowledge’ doctrine salvages free will and divine omniscience by contending that God knows what agents will freely choose under any possible circumstances. I argue, however, that the Leibnizian problem of divine knowledge of human evil is best resolved by applying a Theodicy II distinction between determined, foreseen, and resolved action. This move eliminates deference to middle knowledge. Contingent action is indeed free, but not all action is contingent, and so not all action is free. For Leibniz, then, God’s (...) knowledge extends to the sum pattern of determinates for an act, rather than to contingent events. (shrink)
