In this paper I argue that Leibniz's ethics is a kind of virtue ethics where virtues of the agent are explanatorily primary. I first examine how Leibniz obtained his conception of justice as a kind of love in an early text, Elements of Natural Law. I show that in this text Leibniz's goal was to find a satisfactory definition of justice that could reconcile egoism with altruism, and that this was achieved through the Aristotelian virtue of friendship where friends treat (...) each other as “other selves.” Following this decisive moment, Leibniz adopted an Aristotle‐inspired ethical framework where the virtuous agent is central for moral evaluations. I then show that, despite certain developments, Leibniz's ethics retained this essential feature throughout his career. In Leibniz's later writings, God constitutes the foundation of the moral realm, and the fundamental moral endeavor of human beings consists in the imitation of God. (shrink)

The essay collection "Kant on Proofs for God's Existence" provides a highly needed, comprehensive analysis of the radical turns of Kant's views on proofs for God's existence.— In the "Theory of Heavens" (1755), Kant intends to harmonize the Newtonian laws of motion with a physico-theological argument for the existence of God. But only a few years later, in the "Ground of Proof" essay (1763), Kant defends an ontological ('possibility' or 'modal') argument on the basis of its logical exactitude while he (...) praises the physico-theological argument for its beauty and appeal to the common sense. In the first "Critique" (1781/7), Kant replaces traditional constitutive ontological, cosmological, and physico-theological proofs with his own regulative theoretical and moral-practical religious arguments. He continues to defend a moral argument in the second "Critique" (1788). But in the third "Critique" (1790), Kant reintroduces a physico-theological besides an ethicotheological argument in order to unify the critical system of philosophy. Kant develops further moral arguments and arguments from evil in the "Theodicy" essay (1791) and the "Religion" (1793/4), and still searches for the right kind of proof for God's existence in the "Opus postumum" (1796–1804).—Part one of this volume is dedicated to an analysis of Kant's proofs for God's existence in their historical order that explains which proofs Kant favors or rejects in various periods of his thought. Part two contains a systematic classification of main kinds of proof for God's existence in Kant that outlines the argumentative structure of particular kinds of proof and discusses Kant's potential reasons for their variations and modifications. The essay collection speaks to Kant specialists, philosophers, and theologians, but introduces the topic to non-academic readers also. -/- Contributers: Uygar Abaci (Pennsylvania State University), Craig Bacon (University of South Carolina), Andrew Chignell (Princeton University), Eckart Förster (Humboldt University, Johns Hopkins University), Ina Goy (Beijing Normal University) Paul Guyer (Brown University), Graham Oppy (Monash University), Lara Ostaric (Temple University), Stephen Palmquist (Independent Scholar), Lawrence Pasternack (Oklahoma State University), Konstantin Pollok (University of Mainz), Oliver Sensen (University of Tulane), Allen Wood (Bloomington University, Stanford University).

This chapter discusses Kant's 1763 "possibility proof" for the existence of God. I first provide a reconstruction of the proof in its two stages, and then revisit my earlier argument according to which the being the proof delivers threatens to be a Spinozistic-panentheistic God—a being whose properties include the entire spatio-temporal universe—rather than the traditional, ontologically distinct God of biblical monotheism. I go on to evaluate some recent alternative readings that have sought to avoid this result by arguing that the (...) relevant facts about real modality can be ultimately grounded in God’s powers or thoughts – or that Kant just leaves the grounding relations mysterious. I argue that the textual and philosophical costs of each of these alternative readings are formidable. The chapter concludes with a discussion of the fate of the proof in the critical period. Some commentators think that it disappears altogether, or that it is downgraded such that it produces a mere regulative idea of God as the most real being. I suggest that the proof survives but that the mode of assent it licenses towards its conclusion changes from knowledge to a certain kind of Belief (Glaube). (shrink)

What is the relation between metaphysical necessity and essence? This paper defends the view that the relation is one of identity: metaphysical necessity is a special case of essence. My argument consists in showing that the best joint theory of essence and metaphysical necessity is one in which metaphysical necessity is just a special case of essence. The argument is made against the backdrop of a novel, higher-order logic of essence, whose core features are introduced in the first part of (...) the paper. The second part investigates the relation between metaphysical necessity and essence in the context of HLE. Reductive hypotheses are among the most natural hypotheses to be explored in the context of HLE. But they also have to be weighed against their non-reductive rivals. I investigate three different reductive hypotheses and argue that two of them fare better than their non-reductive rivals: they are simpler, more natural, and more systematic. Specifically, I argue that one candidate reduction, according to which metaphysical necessity is truth in virtue of the nature of all propositions, is superior to the others, including one proposed by Kit Fine, according to which metaphysical necessity is truth in virtue of the nature of all objects. The paper concludes by offering some reasons to think that the best joint theory of essence and metaphysical necessity is one in which the logic of metaphysical necessity includes S4, but not S5.

The problem of Kant's first Critique is the problem of pure reason: how are synthetic judgments possible a priori? Many of his readers have believed that the problem depends upon a delimitation within the class of a priori truths of a class of irreducibly synthetic truths—a delimitation whose possibility is doubtful—because absent this it is not excluded that all a priori truths are analytic. I argue, on the contrary, that the problem depends on nothing more than the human knower's everyday (...) consciousness of her own finitude: her dependence in thinking and knowing on what is given to her. The problem is a difficulty about how the concepts which figure in metaphysical judgments could represent reality given that they cannot do so in the way in which concepts figuring in empirical judgments do. Empirical judgment here functions as exemplary of thought and knowledge because it is exemplary of finite thought and knowledge. Mere analysis could not, therefore, dissolve the problem even in principle, because to say that a concept can be analyzed is not yet to explain the possibility of its real representative power. The significance of the analytic-synthetic distinction in the context of the problem of pure reason is that its formulation allows Kant to say this. (shrink)

Spinoza reasons about impossibilities on a regular basis. But he also says they're unthinkable and that reasoning is a mental process. How can he do this? The paper defends a linguistic account of counterpossible inferences in Spinoza's geometrical method.

One vexing strand of Spinozism asserts that God's nature is more expansive than traditionally conceived and includes properties like being extended. In this paper, I argue that prominent early moderns embrace metaphysical principles about causation, mental representation, and modality that pressure their advocates towards such an expansive account of God's nature in similar ways. I further argue that the main early modern escape route, captured in notions like “eminent containment,” fails to adequately relieve the metaphysical pressures towards Spinozism. The upshot (...) is that those sympathetic with these early modern projects must embrace a costlier option if they are to successfully escape the orbit of Spinoza. (shrink)

There was a consensus in late Scholasticism that evils are privations, the lacks of appropriate perfections. For something to be evil is for it to lack an excellence that, by its nature, it ought to have. This widely accepted ontology of evil was used, in part, to help explain the source of evil in a world created and sustained by a perfect being. during the second half of the seventeenth century, progressive early moderns began to criticize the traditional privative account (...) of evil on a variety of philosophical and theological grounds. Embedded in Scholastic Aristotelianism and applied to problems of evil, privation theory seemed to some like yet another instance of pre-modern pseudo-explanation.1Against this .. (shrink)

I reply to recent criticisms by Uygar Abaci and Peter Yong, among others, of my reading of Kant's pre-Critical of God's existence, and of its fate in the Critical period. Along the way I discuss some implications of this debate for our understanding of Kant's modal metaphysics and modal epistemology generally.

This paper reconsiders Leibniz’s conception of the nature of possible things and offers a novel interpretation of the actualization of possible substances. This requires analyzing a largely neglected notion, the reality of individual essences. Thus far scholars have tended to construe essences as representational items in God’s intellect. We acknowledge that finite essences have being in the divine intellect but insist that they are also grounded in the infinite essence of God, as limitations of it. Indeed, we show that it (...) is critical to understand that this dependence on God’s essence is prior to the dependence on God through divine ideas. Here it is crucial to distinguish questions concerning the ontological status of essences from questions concerning their reality. This yields a fresh view of Leibniz’s theory of creation, which takes seriously his claim that the same thing is first a mere possibility but after creation an actually existent substance. (shrink)

This paper proposes a novel reading of Kant’s account of the dependence of possibility on God in the pre-Critical Beweisgrund. I argue that Kant has a theistic-potentialist conception of the way God grounds possibility, according to which God grounds possibility by his understanding and will. The reason is that Kant accepts what I call the Principle of Possible Existence: If something is possible, then it is possible that it exists. Furthermore, I explore the connection between causal powers and possibility, the (...) influence of Crusius on Kant, and the significance of the distinction between internal and external possibility.

In the first part of the paper I reconstruct Kant’s proof of the existence of a ‘most real being’ while also highlighting the theory of modality that motivates Kant’s departure from Leibniz’s version of the proof. I go on to argue that it is precisely this departure that makes the being that falls out of the pre-critical proof look more like Spinoza’s extended natura naturans than an independent, personal creator-God. In the critical period, Kant seems to think that transcendental idealism (...) allows him to avoid this conclusion, but in the last section of the paper I argue that there is still one important version of the Spinozistic threat that remains. -/- .

Dentro de las tesis que definen la metafísica de Leibniz, destaca aquella según la cual las esencias encierran una pretensión a la existencia. Esta tesis ha despertado un singular interés entre los comentaristas de Leibniz, dando origen a un debate que enfrenta a aquellos que defienden una interpretación metafórica con aquellos que profesan una interpretación literal: si el primer grupo sostiene que tal pretensión ha de entenderse como una atribución metafórica en virtud de la cual las esencias, desprovistas de tal (...) característica, son susceptibles de alcanzar la existencia al ser actualizadas por Dios, para el segundo grupo, las esencias son portadoras en sí de tal característica, la que debe entenderse entonces como una cualidad real e inherente presente en ellas. A partir de un examen de diversos manuscritos de Leibniz, nuestro propósito es reivindicar una interpretación literal de la tesis de la pretensión de las esencias a la existencia, explicando por qué la interpretación metafórica, además de carecer de fundamento, entraña contradicciones.

According to the most prominent principle of early modern rationalists, the Principle of Sufficient Reason [PSR], there are no brute facts, hence, there are no facts without any explanation. Contrary to the PSR, some philosophers have argued that divine ideas are brute facts within Leibniz’s metaphysics. In this paper, I argue against brute-fact-theories of divine ideas, especially represented by Samuel Newlands in Leibniz and the Ground of Possibility, and elaborate an alternative Leibnizian theory of divine ideas.

This paper explores a PSR-connected trail leading from theistic idealism to a form of substance monism. In particular, I argue that the same style of argument available for a Leibnizian form of metaphysical idealism actually leads beyond idealism to something closer to Spinozistic monism. This path begins with a set of theological commitments about the nature and perfection of God that were widely shared among leading early modern philosophers. From these commitments, there arises an interesting case for metaphysical idealism, roughly (...) the thesis that only minds and mind-dependent states actually exist. However, I contend, that same theistic reasoning also leads to an idealist form of substance monism, the view that God is the only actual substance and that almost everything else is merely an intentional object in God’s mind.

We explore a ‘Neo-Cartesian’ account of divine ultimacy that raises the concept of God to its ultimate level of abstraction so that we can do away with even the question of his existence. Our starting point is God’s relation to the logical and metaphysical order of reality and the views of Descartes and Leibniz on this topic. While Descartes held the seemingly bizarre view that the eternal truths are freely created by God, Leibniz stands for the mainstream view that the (...) eternal truths are grounded in God’s nature. We argue that the implausibility of Descartes’ doctrine stems mainly from the assumption that there is a non-epistemic notion of absolute necessity that constitutes the ultimate court of appeal for all modal questions and that this assumption is questionable. We also question the assumption that God’s ultimacy merely requires that all reality be grounded in God in the sense of mere explanation, so that it suffices if the necessary truths are grounded in God’s nature but not in God’s will. This will lead us to a reassessment of Descartes’ position. In the final and main part of the paper, we push Descartes’ doctrine of the creation of the eternal truths to its ‘logical’ conclusion with the aim of getting to a novel conception of ‘God.’.

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)

It is a truth universally acknowledged that a claim of metaphysical modality, in possession of good alethic standing, must be in want of an essentialist foundation. Or at least so say the advocates of thereductive-essence-firstview, according to which all modality is to be reductively defined in terms of essence. Here, I contest this bit of current wisdom. In particular, I offer two puzzles—one concerning the essences of non-compossible, complementary entities, and a second involving entities whose essences are modally ‘loaded’—that together (...) strongly call into question the possibility of reducing modality to essence.

Abstractabstract:In Morning Hours (1785), Moses Mendelssohn presents a proof for the existence of God from the grounding of possibility. Although Mendelssohn claims that this proof is original, it has not received much attention in the secondary literature. In this paper, I analyze this proof and present its historical context. I show that although it resembles Leibniz's proof from eternal truths and Kant's precritical possibility proof, it has unique characteristics that can be regarded as responses to deficiencies Mendelssohn identified in these (...) earlier proofs. I argue that by analyzing the semantics of judgments about dispositions, Mendelssohn provides a novel explanation for the basic premise shared by these proofs, namely that possibility is grounded in actuality. Additionally, this analysis simplifies the inference to a unique infinite mind grounding all possibility. Thus, the proof is worth studying both for historical reasons and for its original account of modal concepts. (shrink)

This thesis was on how God is related to the truth-values of propositions on possible worlds - specifically, those propositions that do not seem to be about Him and constitute His ideas for what to create. It opened with a survey of some historical positions with special emphasis on Aquinas, Leibniz, Spinoza and Kant. Next, some criticisms were given for these so-called deity theories with the most space given to Brian Leftow’s critiques. The second chapter detailed Brian Leftow’s theological modality. (...) In it, secular modality is excogitated in an instant from eternity when God gets a set of creaturely natures in one imaginative act. His preferences that are based on His nature then determine the modality of what God thinks up. A number of objections were raised for the Leftowian project and the last chapter attempted to supplement an older deity theory with some insights from Leftow in order to avoid his initial criticisms.
