I argue against a principle that is widely taken to govern metaphysical explanation. This is the principle that no necessary facts can, on their own, explain a contingent fact. I then show how this result makes available a response to a longstanding objection to the Principle of Sufficient Reason—the objection that the Principle of Sufficient Reason entails that the world could not have been otherwise.

The article explores the idea that according to Spinoza finite thought and substantial thought represent reality in different ways. It challenges “acosmic” readings of Spinoza's metaphysics, put forth by readers like Hegel, according to which only an infinite, undifferentiated substance genuinely exists, and all representations of finite things are illusory. Such representations essentially involve negation with respect to a more general kind. The article shows that several common responses to the charge of acosmism fail. It then argues that we must (...) distinguish the well-founded ideality of representations of finite things from mere illusoriness, insofar as for Spinoza we can have true knowledge of what is known only abstractly. Finite things can be seen as well-founded beings of reason. The article also proposes that within Spinoza's framework it is possible to represent a finite thing without drawing on representations of mind-dependent entities. (shrink)

Leibniz Reinterpreted tackles head on the central idea in Leibniz's philosophy, namely that we live in the best of all possible worlds. Strickland argues that Leibniz's theory has been consistently misunderstood by previous commentators. In the process Strickland provides both an elucidation and reinterpretation of a number of concepts central to Leibniz's work, such as 'richness', 'simplicity', 'harmony' and 'incompossibility', and shows where previous attempts to explain these concepts have failed. This clear and concise study is tightly focussed and assumes (...) no prior acquaintance with Leibniz or optimism. It thus serves as an ideal entry point into Leibniz's philosophy. (shrink)

Over the last half century, possible worlds have bled into almost every area of philosophy. In the metaphysics of modality, for example, philosophers have used possible worlds almost exclusively to illuminate discourse about metaphysical necessity and possibility. But recently, some have grown dissatisfied with possible worlds. Why are horses necessarily mammals? Because the property of being a horse bears a special relationship to the property of being a mammal, they say. Not because every horse is a mammal in every possible (...) world. Some have recently begun to use properties to develop rivals to possible worlds semantics which may someday compare in formal power and capture the different systems of modal logic. In this paper, I do two things. I first offer a quick primer on possible worlds semantics. Then I discuss three rivals and the work they have left to do. (shrink)

The proposition "God chooses the best" is for Leibniz an undeniable truth, as well as a fundamental premise in both his explanation of this world's existence and his theodicy. Leibniz thought it was necessary to clarify its modal status, in virtue of this matter's connection with God's freedom. Nevertheless, while dealing with this problem, he was led to violate his own modal theory's principles, in order to sustain the contingency of that proposition. This paper intends to show that Leibniz's main (...) view regarding the modality of this proposition represents a sort of exception in the framework of his modal conception, and that this uncertainty reveals the profound reasons of his numerous textual hesitations on the subject.

En una conocida carta redactada en 1671, Leibniz formula un esquema argumental que intenta resolver el problema de la existencia del mal, pero que sorprende por una conclusión necesitarista, según la cual toda la cadena de eventos existentes es la óptima, y por tanto es necesaria. El presente trabajo propone una reconstrucción detallada del argumento y un análisis de su significación modal. Este análisis revela que la necesidad atribuida por Leibniz al mundo actual expresa la fuerza modal que adquiere lo (...) óptimo en su filosofía, ya en 1671, como principio que rige indefectiblemente la acción de Dios.

As a lifelong Lutheran who resisted numerous attempts by Catholic acquaintances to convert him, one might reasonably expect Leibniz to have followedthe orthodox Lutheran line on disputed doctrinal issues, and thus held amongst other things that the doctrine of purgatory was false. Yet there is strong evidencethat Leibniz personally accepted the doctrine of purgatory. After examining this evidence, I determine how Leibniz sought to justify his endorsement of purgatory and explain how his endorsement sits alongside his frequent rehearsal of familiar (...) Protestant arguments against the doctrine. I then examine some of Leibniz’s other theological and philosophical commitments, including those on the afterlife, in order to tentatively tease out further details of the form of purgatory that wonhis approval. In considering these issues, I aim to make clear the extent to which Leibniz’s philosophical thinking underpins and shapes his theological beliefs. (shrink)

Leibniz believed in a God that has the power to create beings and whose existence could be a priori demonstrated. Kant objected that similar demonstrations all presuppose the false claim that existence is a real property. Russell added that if existence were a real property Leibniz should have concluded that God does not actually have the power to create anything at all. First, I show that Leibniz’ conception of existence is incompatible with the one that Russell presupposes. Subsequently, I argue (...) that on Leibniz’ conception of existence Russell’s objection is immediately undermined. (shrink)

Leibniz has long faced a challenge about the coherence of the distinction between necessary and contingent truths in his philosophy. In this paper, I propose and examine a new way to save genuine contingency within a Leibnizian framework. I conclude that it succeeds in formally solving the problem, but at unbearable cost. I present Leibniz’s challenge by considering God’s choice of the best possible world (Sect. 2). God necessarily exists and necessarily chooses to actualise the best possible world. The actual (...) world therefore could not be different, for if it were different it would be a distinct and inferior world and hence would not be created. In Sect. 3 I defend Leibniz from this challenge. I argue that while it is necessary for God to choose to create the best possible world, it is not necessary for any world to be the best possible. This is because the criterion for judging perfection can itself be contingent. Different criteria will judge different worlds as the best. Thus it is necessary for God to create the best, but not necessary which is the best. Distinguishing between possible worlds in Leibniz’s sense and in the modern sense allows a fuller exposition of this position. There are worries that can arise with the claim that the criterion of perfection is contingent. I consider two of the most pressing (Sect. 4). The first argues that the criterion is in God’s understanding and hence is necessary; the second alleges that a contingent criterion of perfection violates Leibniz’s cherished Principle of Sufficient Reason. These worries are well-grounded, and examining them reveals a deep incompatibility between this solution and Leibniz’s metaphysical views. I conclude that there is a real solution available, but that it is unacceptable to Leibniz or a Leibnizian. The search for a genuine solution that is genuinely Leibnizian goes on. (shrink)

Leibniz holds that we cannot give an account of the synchronic and diachronic identity of a person without appealing to a substance. This paper analyses his reasons for this anti-Lockean thesis. It first looks at his theory of substance, paying particular attention to his commitment to the Principle of Sufficient Reason: the existence of a well-ordered series of mental states cannot be sufficiently explained without reference to a substance. The paper then examines the distinction Leibniz draws between the substance as (...) the “real person” and the “appearing person” that comes into existence through reflexive consciousness. It argues that there can be no appearing person without a real person and looks at the relationship between these two types of person. Leibniz’s distinction is still relevant because it shows that questions concerning the metaphysical constitution of a person need to be carefully distinguished from questions concerning the psychological construction of a personality.

According to Michael Almeida, reflections on free will and possibility can be used to show that the existence of an Anselmian God is compatible with the existence of evil. These arguments depend on the assumption that an agent can be free with respect to an action only if it is possible that that agent performs that action. Although this principle enjoys some intuitive support, I argue that Anselmianism undermines these intuitions by introducing impossible options. If Anselmianism is true, I argue, (...) then both God and creatures may be free to do the impossible. (shrink)

O problema da corporalidade em Leibniz se vincula necessariamente à discussão sobre o estatuto da matéria em uma Metafísica cuja base são as mônadas imateriais. Veremos que, neste contexto, o material deverá ser fenomênico, mas nem por isso ilusório. O objetivo deste trabalho é mostrar como o campo fenomênico, cujo caso exemplar é o corpo, pode ganhar um suporte metafísico e racionalmente justificado, constituindo o que Leibniz chama de fenômenos bem fundados. Para tal, deverá ser feito um exame cuidadoso da (...) natureza das Forças no pensamento leibniziano e de como elas apresentam o vínculo procurado entre Física e Metafísica. Leibniz on Phenomenon and CorporalityThe problem of corporality in Leibniz is necessarily attached to the discussion on the nature of matter in a Metaphysics whose basis are the immaterial monads. We will see that, in this context, although the material must be phenomenic, it is not necessarily ilusory. The aim of this paper is to show how the phenomenic domain, whose exemplar case is the body, may be metaphysically founded and rationally justifyed, constituting what Leibniz calls well founded phenomena. In order to do it, it is necessary to examine Leibniz's conception of the nature of the Forces and how they could present the link between Physics and Metaphysics. (shrink)

Everyone interested in Leibniz ought to read this fine, stimulating book. It is admirably written in the tradition exemplified by the references below and will especially appeal to those familiar with the analytical exposition in those works.

Two familiar worldviews dominate Western philosophy: materialist atheism and Abrahamic theism. One exciting development in recent philosophy of religion is the exploration of alternatives to both theism and atheism. This paper explores two alternatives: axiarchism and ananthropocentrism. Drawing on the long tradition of Platonism, axiarchists such as John Leslie, Derek Parfit and Nicholas Rescher posit a direct link between goodness and existence. The goodness of a possible world is what makes it actual. Ananthropocentric Purposivism holds that the universe has a (...) purpose and that humans are irrelevant to that purpose. If there is a God, then God cares about what matters, but we do not matter to God. (shrink)

The article reconstructs a brief controversy between H. More, G. W. Leibniz and J. G. Wachter about the Kabbalah, or what they called ‘the philosophy of the Hebrews’. I study in particular the status of the proposition ‘nothing comes out of nothing’ in their exchanges - a proposition they all agreed was a fundamental kabbalist axiom while having differing views as to the prospects of reconciling that position with Christianity. I show how Wachter’s curious Kabbalistico-Spinozism provided the stage for an (...) indirect philosophical encounter between Leibniz and More that highlights not only their respective positions on the Kabbalah, but also suggests some important philosophical agreement between them regarding divine transcendence and the nature of creation.

The editors of this volume, in their introduction, take Jonathan Bennett’s A Study of Spinoza’s Ethics as the exemplar for the eleven essays collected here, hailing Bennett’s book as setting “new standards for philosophical research on Spinoza”. Bennett’s work is indeed a worthy model. Aside from its more generic virtues, such as learnedness and conceptual rigor, perhaps what is most distinctive about Bennett’s treatment of Spinoza is his method, which he calls the “collegial approach.” This method proceeds by studying “the (...) texts in the spirit of a colleague, an antagonist, a student, a teacher—aiming to learn as much philosophy as one can from studying them.” Bennett has, employing this approach, produced a large number of useful works on early modern philosophers, and his efforts concerning Spinoza are among the best of them. But does Bennett’s example provide any unity for this collection? A number of these essays, Della Rocca’s and Manning’s, for example, indeed take what could be fairly described as a collegial approach to the study of Spinoza. Still others, however, such as Kulstad’s, place more emphasis on historical scholarship than the collegial approach prescribes. This matters, however, very little. Exemplary as Bennett’s work is, the study of the history of early modern philosophy has, in recent years, benefited from the work of scholars using a wide variety of methods. I think it fair to say that the essays collected in this volume, not at all to their detriment, reflect this diversity. (shrink)

The radical redefinition of the landscape of physics that followed the contributions of Niels Bohr and Werner Heisenberg at the start of the 20th century led to plethora [of] new perspectives on age-old metaphysical questions on determinism and the nature of reality. The main contention of this article is that the work of Gilbert Simondon - whose magnum opus possesses a scope uniting the most basic philosophical concerns with the most recent breakthroughs in natural sciences - is highly relevant for (...) an adequate understanding of the split between determinism and indeterminism, as well as the underlying presuppositions which have driven some influential contributions to this topic. To this end, the article shows that the more deterministic interpretation of quantum mechanics offered by David Bohm and Louis de Broglie proves to be a valuable reference point for a more precise use and understanding of Simondon'ss transductive logic - especially when its philosophical lapses are considered closely. Finally, following the considerations of both thinkers, we aim at a more precise reconsideration of the stakes of indeterminism in modern physics, as well as a restructuration of what is often understood as a polarization.

This paper characterizes various responses to the question, 'Why does our universe exist?' Some responses- that the question is senseless, that the existence of our universe is logically necessary- are implausible. Adjudication between more plausible responses requires us to evaluate the argument from the 'fine-tuning' of the universe, a refurbished version of the argument from design that appeals to cosmology rather than biology. The evidence of fine-tuning should lead us to adopt, albeit provisionally, cosmological fecundity, the hypothesis that there exist (...) many universes of varying characters. The existence of our universe is thereby rendered less surprising. This is to be preferred both to the theistic hypothesis and to the view that the existence of our universe requires no explanation.

This article examines Leibniz's philosophy of causation with the aim of clarifying how causes are related to their effects. I argue that, much like J. L. Mackie's INUS conditions, Leibnizian causes are members of complex causal conditions. More precisely, Leibniz identifies causes with elements of complex causal conditions, where the complex condition as a whole is sufficient for the effect, and the cause is a necessary part of that condition. This conception of causation is able to incorporate Leibniz's many other (...) definitions of ‘cause’, thereby resolving what appear to be internal inconsistencies in his philosophy of science. Introduction The ingredients of causation Causes and conditions Causes as INUS conditions Conclusion. (shrink)

Leibniz's philosophy of time, often seen as a precursor to current forms of relationalism and causal theories of time, has rightly earned the admiration of his more recent counterparts in the philosophy of science. In this article, I examine Leibniz's philosophy of time from a new perspective: the role that tense and non-tensed temporal properties/relations play in it. Specifically, I argue that Leibniz's philosophy of time is best (and non-anachronistically) construed as a non-tensed theory of time, one that dispenses with (...) tensed temporal properties such as past, present, and future. In arguing for this thesis, I focus on the three facets of Leibniz's philosophy most relevant for evaluating his commitment to a B-theory of time: (1) the nature of change, (2) the reality of the future, and (3) the truth-conditions for tensed temporal statements. Despite prima facie evidence to the contrary, I show that a close examination of Leibniz's views on these topics provides compelling evidence for interpreting his philosophy of time as a B-theory of time.

To explain why God is not the author of sin, despite grounding all features of the world, the early Leibniz marginalized the divine will and defined existence as harmony. These moves support each other. It is easier to nearly eliminate the divine will from creation if existence itself is something wholly intelligible, and easier to identify existence with an internal feature of the possibles if the divine will is not responsible for creation. Both moves, however, commit Leibniz to a necessitarianism (...) that is stronger than what prominent interpreters such as Robert Sleigh and Mogens Lærke have found in the early Leibniz, and stronger than the necessitarianism that threatens his later philosophy. I defend this reading of Leibniz and propose that some features of Leibniz’s later metaphysics, including his “striving possibles” doctrine, are an artifact of the effort to rescue the early theodicy from its unwelcome implications.

Resumen En el presente trabajo analizo el concepto de cuerpo en los escritos maduros de Leibniz. En el marco del debate contemporáneo acerca del estatus de la sustancia corpórea examino el entramado de las tres nociones sobre las que se construye la metafísica leibniziana de los cuerpos, a saber, la de materia prima, la de cuerpo orgánico y la de extensión. En cada caso evalúo el estatus ontológico que Leibniz les reconoce así como el papel que cumplen en su metafísica.In (...) this paper I examine the concept of body in Leibniz’s mature writings. In the context of the contemporary debate on the status of the corporeal substance, I analyze the relation between the three notions from which he builds his metaphysics of bodies, namely, the primary matter, the organic body, and the extension. For each case I evaluate their ontological status and the role they play in his metaphysics. (shrink)

En el presente trabajo analizamos la reforma que Leibniz propone entre 1677 y 1695 en la noción de cuerpo y, a partir de ello, esclarecemos el concepto de sustancia corpórea que presenta en esos años.

This anthology is about the signal change in Leibniz’s metaphysics with his explicit adoption of substantial forms in 1678-79. This change can either be seen as a moment of discontinuity with his metaphysics of maturity or as a moment of continuity, such as a passage to the metaphysics from his last years. Between the end of his sejour at Paris and the first part of the Hanover period, Leibniz reformed his dynamics and began to use the theory of corporeal substance. (...) This book explores a very important part of the philosophical work of the young Leibniz. Expertise from around the globe is collated here, including Daniel Garber’s work based on the recent publication of Leibniz's correspondence from the late 1690s, examining how the theory of monads developed during these crucial years. Richard Arthur argues that the introduction of substantial forms, reinterpreted as enduring primitive forces of action in each corporeal substance, allows Leibniz to found the reality of the phenomena of motion in force and thus avoid reducing motion to a mere appearance. Amongst other themes covered in this book, Pauline Phemister’s paper investigates Leibniz’s views on animals and plants, highlighting changes, modifications and elaborations over time of Leibniz’s views and supporting arguments and paying particular attention to his claim that the future is already contained in the seeds of living things. The editor, Adrian Nita, contributes a paper on the continuity or discontinuity of Leibniz’s work on the question of the unity and identity of substance from the perspective of the relation with soul and mind.

Loving God is our highest perfection for Leibniz. It secures our belief and trust in the Creator, which is integral to the sciences as well as faith. Those who love God have justification for reasoning, that is, they can rationally expect to arrive at truth. This is because love is a receptivity to the perfection all of things; loving God, then, is a disposition and tendency toward the most perfect being, the ens perfectissimum. Individuals who perceive the divine nature “do (...) not merely fear the power of the supreme and all-seeing monarch,” Leibniz writes, “but are assured of his beneficence, and lastly—and what brings everything together—burn with a love of God above all else.”1 In my dissertation, I argue that Leibniz’s qualification should be taken seriously: love of God “brings everything together.” The subject of my dissertation can be stated schematically. It consists of two pairs of claims, one pair philosophical, the other theological: A moral quality is required to secure our reason. From a most perfect unity, a moral quality follows. Love of God is our highest perfection. Love of God secures our reasoning. Both concern the security of reason, by which I mean the rational motivation for reasoning itself. They are reasons we ought to expect reasoning to lead to truth. Yet they do not form a tight demonstration: while an inference is clearly at work in the first pair, there are no inferences in the second. Also, there is a distinction between a moral quality and love for God. Unless they are identified, Leibniz’s philosophy and theology secure reasoning apart from one another. In 1686, Leibniz wrote his well-known “Discourse on Metaphysics.” A few months after, he composed a theological treatise, Examination of the Christian Religion. These texts, I argue, should be read side by side, and the first chapter compares how divine perfection secures our reasoning in both texts. Some Moderns’ notion of perfection—namely, Descartes’, Spinoza’s, and Malebranche’s—fail to secure our reasoning because their views entail arbitrariness in the world and the divine nature. But a proper sense of perfection, one that includes a moral quality, secures our reasoning by ensuring that everything is amenable to reason. Descartes also sought to secure our reasoning, and for the second and third chapters I compare his account with Leibniz’s own, then draw out the latter’s criticisms. For Descartes, the deity’s moral quality is characterized by an indifferent will, which is eminently and formally revealed throughout creation. Although recognizing the infinite source of all things directs our attention appropriate in the Cartesian system, Leibniz criticizes Descartes’ detached and indifferent God. When our disposition toward God is not characterized by love, we are less rational than otherwise. Leibniz finds intolerable moral implications in the Cartesian system, and I work out these implications in chapter three. Descartes’ criteria of true and false ideas does not settle dispute, but relies on “interior testimony.” Proper reasoning, then, does not tend toward unity among persons, and this is especially problematic in religious debate. Descartes’ method is Stoic, which also leads to trouble when it comes to church unity: one remains in the church by a sheer act of will, which can violate reason. Leibniz views such a detachment of faith and reasoning as dangerous, besides impoverishing the concept of reason altogether. Leibniz’s notions of God and perfection secure our reason by engendering love for God. “Discourse” and Examen begin with a moral disposition and tendency. In the last chapter, I argue that this is the case by considering two criteria Leibniz adopts—his test for perfection and the kinds of knowledge—as well as the foundation of his logic at the time. Leibniz can tolerate provisional beginnings, hypothetical truths, and original sin because of his robust conception of love. He distinguishes two ways we love God: spes, or hope, is a disposition or tendency to natural perfection, and caritas, or esteem, affection, or love, regards divine perfection. These states orient us according to the divine plan. Miracles are within the world as an effect of the deity’s moral quality: they are a means God personally relates to rational beings. Miracles reveal the moral effects of our perception of phenomena generally, included the regularity observed and classified by science. So, to conclude, I compare Leibniz’s discussion of revelation in Examen with his discussion of miracles in “Discourse” to draw out the significance of miracles for him. Besides much debate on the implications of miracles for his conception of substance, I argue that there is a moral motivation for retaining miracles, even those of the second rank. (shrink)

How many formulations of Principle of Sufficient Reason can one find in Leibniz's works? This paper suggests that there are at least two different formulations, which start from different basic concepts, trying to sketch the relations between them and the evolution from the more ancient formulation to the mature one.

Kant wrote in the Only Possible Argument in Support of a Demonstration of the Existence of God, that existence is not a predicate of things. In this paper I argue that his thinking is based on the same view already in the New Elucidation, written in 1755. In this early text, Kant carefully distinguishes the grounds of existence from grounds of knowledge and argues that contingent existence always has an antecedently determining ground. I examine how Kant thinks that God contains (...) the extralogical grounds that are required for things not only to exist but also to undergo change and interact with other things. I also consider briefly how the New Elucidation could help us to understand Kant’s mature view on the grounds of existence. (shrink)

Si Dios es la razón suficiente del mundo, entonces parece seguirse que todos los eventos son consecuencia necesaria de un ser necesario. Para evadir esta conclusión, Leibniz formula en la década de 1670 una concepción modal que funda la contingencia en un rasgo lógico e intrínseco de las ideas de las cosas: la posibilidad de concebir la idea contraria sin contradicción. Hacia 1686, Leibniz complementa esta primera concepción con lo que considera su solución definitiva al problema de la contingencia: la (...) teoría del análisis infinito. Sin embargo, en otros escritos de ese año, propone dos vías alternativas de fundamentación de la contingencia. Este trabajo sugiere que esa pluralidad de modelos explicativos converge en una concepción integral de las modalidades que subyace como trasfondo de la reflexión modal leibniziana. If God is the sufficient reason for this world, then it seems to follow that every event is a necessary consequence of a necessary being. in order to avoid this conclusion, Leibniz states, during the 1670's, a modal conception that grounds contingency on a logical feature which is intrinsic to the ideas of things: the possibility of conceiving the opposite idea without contradiction. Towards 1686, Leibniz complements this first conception with what he considered to be his definitive solution to the problem of contingency: the theory of infinite analysis. However, in other writings from the same year, he proposes two different ways to explain contingency. This paper suggests that this plurality of models converges in a global conception of modalities, which lies at the background of Leibniz's modal thought. (shrink)

En sus últimos años, Leibniz emplea el concepto de necesidad moral para cualificar la elección divina de lo óptimo. Sin embargo, Leibniz no explica este concepto con precisión. El presente trabajo intenta mostrar que la necesidad moral leibniziana no puede entenderse como una modalidad puramente deóntica, porque ello contraría los fundamentos metafísicos que hacen al carácter teleológico de su ética. El artículo propone también una interpretación del contenido alético de tal noción, basada en la conexión necesaria que Leibniz parece atribuir (...) a la relación entre la voluntad y la tendencia al bien. Dicha necesidad afirmaría que, aun cuando toda elección es contingente, en tanto entraña una infinidad de consideraciones, el Dios leibniziano está metafísicamente necesitado a seguir el criterio de lo mejor. In his last years, Leibniz employs the concept of moral necessity to qualify God's choice of the best. However, he doesn't explain this concept accurately. This paper intends to show that leibnizian moral necessity cannot be conceived as a purely deontic modality, because it would be contrary to the metaphysical grounds which make Leibniz's ethics strictly teleological. This paper also proposes an interpretation of the alethic content of this concept, based on the necessary connection that Leibniz seems to assign to the relationship between free will and the tendency towards good. What this necessity entails is that, for Leibniz, even though the infinity of reasons involved makes every choice contingent, God is metaphysically necessitated to follow the rule of the best.

En este artículo, presentamos primero un análisis de la proposición “Dios elige siempre lo mejor”, con el fin de indagar qué tipo de necesidad cabe atribuírsele. Puesto que Leibniz rechaza la necesidad geométrica en el ámbito de la libre elección divina, examinamos luego qué clase de relación hay entre el entendimiento y el bien, es decir, si corresponde prioritariamente a la razón juzgar sobre el bien o lo mejor. Del mismo modo, analizamos a continuación el vínculo que liga a la (...) voluntad con el bien, por cuanto este último parece ser, al mismo tiempo, el objeto natural de la voluntad. En ambos casos, el análisis se aplica tanto a Dios como a las criaturas racionales. Una aparente inconsistencia parece suscitarse entre un entendimiento y una voluntad que “se disputan” el mismo objeto. Nuestro objetivo es mostrar que, aunque la prioridad de examinar sobre el bien pueda recaer en una u otra facultad, según el contexto escritural, la cuestión carece de sentido al aplicársela a Dios. En suma, la ambivalencia se diluye cuando advertimos que ello resulta de una ficción humana, a saber que hay un hiato entre deber y querer. (shrink)

I have three main objectives in this essay. First, in chapter 2, I shall put forward and justify what I call worldlessness, by which I mean the following: All truths (as well as falsehoods) are wholly independent of any circumstances, not only time and place but also possible worlds. It follows from this view that whatever is actually true must be taken as true with respect to every possible world, which means that all truths are (in a sense) necessary. However, (...) the account I shall propound is different from what is known in the trade as necessitarianism, i.e. the view that there is only one possible world, viz. the actual one, for the doctrine of the worldlessness of truth values, despite its commitment to the necessity of truths and falsehoods, is quite compatible with the idea of there being other possible worlds. Another important issue in chapter 2, explored in particular in section 2.12, is the claim that there is no real change in the world. Secondly, in chapter 3 I consider the eminent traditional argument for determinism, deriving from Aristotle, namely, logical determinism, i.e. determinism justified by an appeal to the logical principle of bivalence (that all proper statements, including those concerning the future, are either true or false). In this connection I try to show that, (i), the formulation of the conclusion of this argument as "Whatever will happen will happen of necessity" is implausible, at least from the modern point of view, (ii), the formulation as "Whatever will happen will happen inevitably" is more to the point, and (iii), on the basis of the worldless and timeless aspect advocated in chapter 2, this latter formulation is quite harmless, essentially amounting to the trivial statement, "Whatever will happen will happen". Thirdly, in chapter 4 I study theological determinism, or determinism that arises from God's supposed providential control over everything that happens. In this connection, I shall survey some historical accounts of the relation between human free will and determinism (not only theological but also causal determinism); the philosophers the views of whom I shall attend to include Chrysippus, St. Augustine, Boethius and Aquinas. I shall in particular consider G.W. Leibniz' theodicean aspirations, viz. his solution to the problem of evil and, especially, his compatibilist attempts to reconcile human free will with the strictly deterministic flow of actual events. I think it is important to try to explicate Leibniz' ingenious account of these matters, since it seems that it has not been fully appreciated in the literature, not even by contemporary Leibniz scholars (such as B. Mates, R.C. Sleigh, C. Wilson, R.M. Adams and D. Rutherford). In providing the Leibnizian compatibilist solution of the problem of determinism and freedom in chapter 4, I shall utilize the approach of chapter 2. (shrink)

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.

We claim that Kant's doctrine of the "transcendental ideal of pure reason" contains, in an anticipatory sense, a second-order theory of reality (as a second-order property) and of the highest being. Such a theory, as reconstructed in this paper, is a transformation of Kant's metatheoretical regulative and heuristic presuppositions of empirical theories into a hypothetical ontotheology. We show that this metaphysical theory, in distinction to Descartes' and Leibniz's ontotheology, in many aspects resembles Gödel's theoretical conception of the possibility of a (...) supreme being. The proposed second-order modal formalization of the Kantian doctrine of the "transcendental ideal" of the supreme being includes some specific features of Kantian general logic like "categorical", "hypothetical", and exclusive disjunctive propositions as basic forms.

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)

Descartes held the seemingly bizarre doctrine that the eternal truths are freely created by God. This 'Creation Doctrine' has been the subject of great misunderstandings and ridicule from philosophers and theologians from the seventeenth century to the present. ;This dissertation is a sympathetic interpretation of Descartes' Creation Doctrine. After first briefly examining some alternative views concerning the relationship between the eternal truths and God, I argue that Descartes is committed to the Creation Doctrine because of his acceptance of traditional theological (...) views concerning the nature of God, in particular, God's simplicity and freedom. I then argue that Descartes' Creation Doctrine, contrary to the claims of some recent commentators, does not entail any bizarre modal theses. For instance, the fact that God could have willed that the eternal truths are false does not entail that there are no necessary truths. I conclude by offering an interpretation of Descartes' explanation of the necessity of the eternal truths. ;We will see that the Creation Doctrine is theologically well-grounded, does not affect ordinary modal claims, and in fact, guarantees the necessity of the eternal truths.

In this paper, I will try to exploit the implication of Leibniz's statement in Monadology (1714) that "there is a kind of self-sufficiency which makes them [monads] sources of their own internal actions, or incorporeal automata, as it were" (Monadology, sect.18). Leibniz's monads are simple substances, with no shape, no magnitude; but they are supposed to produce the phenomena resulting from their activities, which for us humans look as the whole world, the nature. The activities of a monad are characterized (...) by mental terms, perceptions (internal states) and appetites (which change the internal state). By means of perceptions, a monad becomes a "perpetual living mirror of the universe"; it can receive the information of other monads and it can send its own, in turn, to others. The communication and interconnection thus produced result in the physical and the psychical phenomena observed by us, humans. According to Leibniz, all monads are governed by the teleological law given by the God, and the world of phenomena are governed by the causal and mechanical law. Leibniz argues that there is a pre-established harmony among the monads so that this double character is no problem. Now, I will propose an informational interpretation of monadology, which regards the monads as an automaton governed by the God's program and arranged appropriately; and I will argue that Leibniz's scenario can be defended in terms of this interpretation. The crucial part of this interpretation is that the God's program and the monads' activities are related with the phenomenal world by means of a coding by God. This interpretation is also defended on the textual basis, with a special reference to Leibniz's distinction between primitive and derivative forces. Drawing on R. M. Adams's careful reading of Leibniz's texts (Leibniz: Determinist, Theist, Idealist, 1994), I will argue that his rendering is quite in conformity with my interpretation, although he does not seem to be aware of the notion of coding.

In this dissertation, I develop an interpretation of Leibniz on modality and free will. I do so for two reasons: first, I am attempting to revitalize the notion that Leibniz is the predecessor of contemporary modal semantics; second, I am using Leibniz's philosophical system to motivate responses to contemporary philosophical issues in modality and free will. In Chapter One, I argue that Leibniz's basic principles are plausible theoretical tools that ought to be used by contemporary philosophers in developing their philosophical (...) systems. In Chapter Two, I develop Leibniz's views on the nature of individuals. I argue that possible individuals are actually of the same sort as individuals in the actual world--possible individuals and actual individuals are complete creatures that do not differ ontologically from each other. In Chapter Three, I argue that Leibniz's views on possible individuals make him a modal realist and compare his view with contemporary modal realism in order to support this claim. I also argue that counterparts avoid many of the problems set for them by contemporary thinkers; I end with the ways that Leibniz's view differs from contemporary accounts. In Chapter Four, I argue that Leibniz provides two different analyses of modality. The first is an infinite analysis account; the second is a possible worlds account. I argue that these two accounts are compatible and amount to two different descriptions of the same theory of modality. I address objections to each account in order to show this. In Chapter Five, I argue that Leibniz is a compatibilist about free will. Importantly, I argue that it is precisely Leibniz's account of modality that allows for this compatibilism, as against a necessitarian like Spinoza. I then use Leibniz's account to challenge contemporary libertarians about free will on the basis of the principle of sufficient reason. I also show how Leibniz can help semicompatibilism avoid a worry concerning necessitarianism. At the end of the day, I claim that adopting elements of Leibniz's system can help us better understand modality and the freedom of the will and can be an aid in furthering contemporary philosophical theory.

Apresento e desenvolvo neste artigo o problema da prova sortuda, analisando duas soluções para ele presentes na literatura. A primeira delas consistira em alegar que mostrar que o predicado está contido no sujeito não basta como demonstração da verdade de uma proposição, sendo preciso que se prove ainda que a noção relativa ao sujeito é logicamente consistente. A segunda repousaria em uma hierarquização modal, por assim dizer, dos pre- dicados integrantes de uma noção individual. Após exibir as razões que me (...) levam a rejeitar essas duas soluções, apresento os traços fundamentais de uma interpretação que me parece resolver o problema de maneira satisfatória. Minha posição envolve conceder ao Princípio da Razão Suficiente um papel central na compreensão do que significa, para Leibniz, provar que um determinado predicado está contido na noção relativa a um certo indivíduo.
