Bringing together two aspects of Thomas Aquinas's thought that have been studied separately: his theory of God's concurrence and his theory of instrumental causality, I show how he uses the latter (which I discuss first) to clarify the Proclusian principle that the first cause has a greater influence on an effect than the proximate causes. Thanks to this theory, Aquinas accounts for the fact that it is God who confers existence to every new being that is produced by natural processes, (...) without however negating the agency of secondary, created causes.

Leibniz thinks that every created substance is causally active, and yet causally independent of every other: none can cause changes in any but itself. This is not controversial. But Leibniz also thinks that every created substance is existentially independent of every other: it is metaphysically possible for any to exist with or without any other. This is controversial. I argue that, given a mainstream reading of Leibniz’s essentialism, if one accepts the former, uncontroversial interpretation concerning causal independence, then one ought (...) also to accept the latter, controversial one concerning existential independence. This is a new way to defend the ‘existential independence’ interpretation. Moreover, this defense provides a new approach for defending the broadly ‘non-logical’ interpretive camp in the longstanding debate over Leibniz’s views on incompossibility, against perhaps the strongest objection leveled by advocates of the opposing broadly ‘logical’ interpretation.

This paper aims to resolve an unremarked-upon tension between Anne Conway’s commitment to the moral responsibility of created beings, or creatures, and her commitment to emanative, constant creation. Emanation causation has an atemporal aspect according to which God’s act of will coexists with its effect. There is no before or after, or past or future in God’s causal contribution. Additionally, Conway’s constant creation picture has it that all times are determined via divine emanation. Creaturely agency, by contrast, is fundamentally temporal, (...) occurring successively over time. It is unclear how creatures can count as emanative causes, which coexists with its effect, given that their agency is limited by time, proceeding from before to after, or past to future. Conway’s account of divine justice in the progress of time, however, requires that creatures are causally responsible. That is, moral responsibility requires causal responsibility. I propose that Conway’s distinction between vital motion and local motion enables a resolution of the tension. Vital motion contributes an atemporal aspect to creaturely agency so that creatures can count as secondary emanative causes. (shrink)

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

A plausible reading of Berkeley’s view of voluntary motion is occasionalism; this, however, leads to a specious conclusion against his argument of human action. Differing from an unqualified occasionalist reading, I consider the alternative reading that Berkeley is a conservationist regarding bodily motion by the human mind at will. That is, finite minds (spirits) immediately cause motions in their body parts, albeit under the divine conservation. My argument then comports with the conservationist reading from three perspectives: (i) theodicy that the (...) human mind is held liable for sinful actions; (ii) an account of the human mind influencing other minds; and (iii) an improper but necessary directing principle of the human mind. This article is a stepping stone to grasping why the conservationist reading is more coherent than the occasionalist one. (shrink)

In a recent paper, Alvin Plantinga defends occasionalism against an important moral objection: if God is the sole direct cause of all the suffering that results from immoral human choices, this causal role is difficult to reconcile with God’s perfect goodness. Plantinga argues that this problem is no worse for occasionalism than for any of the competing views of divine causality; in particular, there is no morally relevant difference between God directly causing suffering and God indirectly causing it. First, we (...) examine Plantinga’s moral parity argument in detail and offer a critical evaluation of it. Then we provide a positive argument, based on the doctrine of doing and allowing, to show why there is a morally relevant difference between God’s direct and indirect causation of suffering.

How does God govern the world? For many theists “laws of nature” play a vital role. But what are these laws, metaphysically speaking? I shall argue that laws of nature are not external to the objects they govern, but instead should be thought of as reducible to internal features of properties. Recent work in metaphysics and philosophy of science has revived a dispositionalist conception of nature, according to which nature is not passive, but active and dynamic. Disposition theorists see particulars (...) as being internally powerful rather than being governed by external laws of nature, making external laws in effect ontologically otiose. I will argue that theists should prefer a dispositionalist ontology, since it leads them toward the theory of concurrentism in divine conservation, rather than occasionalism, and revives the distinction between internal and external teleology. God on this view does not govern the world through external laws of nature, but rather through internal aspects of powerful properties. (shrink)

This is about the tension between Epicurean and Galilean accounts of motion in Gassendi. For my more recent thoughts on this, see http://philpapers.org/rec/LOLCEG.

I address an apparent conflict between Spinoza’s concepts of immanent causation and acting/doing [agere]. Spinoza apparently holds that an immanent cause undergoes [patitur] whatever it does. Yet according to his stated definition of acting and undergoing in the Ethics, this is impossible; to act is to be an adequate cause, while to undergo is to be merely a partial cause. Spinoza also seems committed to God’s being the adequate cause of all things, and, in a well-known passage, appears to deny (...) categorically that God is capable of undergoing. How then can God also be the immanent cause of all things, as Spinoza claims? On the basis of a close reading of the passage in question, I argue that Spinoza actually distinguishes between two senses of undergoing. An immanent cause undergoes not by being a partial cause but rather by being the metaphysical subject of its effect. While this sense of undergoing has its roots in scholasticism, Spinoza’s willingness to attribute such a capacity to undergo to God is idiosyncratic and reveals important ways in which his understanding of essence, perfection, and causation differs from the scholastic model.

This paper explores the theory of freedom that Emilie du Châtelet advances in her essay “On Freedom.” Using contemporary terminology, we can characterize this theory as a version of agent-causal compatibilism. More specifically, the theory has the following elements: (a) freedom consists in the power to act in accordance with one’s choices, (b) freedom requires the ability to suspend desires and master passions, (c) freedom requires a power of self-motion in the agent, and (d) freedom is compatible with moral necessity (...) but not with physical necessity. While these elements may at first appear disparate, the paper shows that they fit together quite well. The resulting theory is a surprising combination of doctrines that appear to be based on Samuel Clarke’s libertarian account of free will and doctrines that are reminiscent of the compatibilist accounts of John Locke, Anthony Collins, Gottfried Leibniz, and Thomas Hobbes.

The employment by seventeenth-century natural philosophers of stock theological notions like creation, immensity, and eternity in the articulation and justification of emerging physical programs disrupted a delicate but longstanding balance between transcendent and immanent conceptions of God. By playing a prominent (if not always leading) role in many of the major scientific developments of the period, God became more intimately involved with natural processes than at any time since antiquity. In this discussion, I am particularly concerned with the causal and (...) spatio-temporal relations between God and nature in the seventeenth century as recent scholarship has revealed how dramatically traditional conceptions of these relations were transformed by philosophers and scientists like Descartes, Malebranche, More, and Newton.

For theological reasons, medieval thinkers maintained that sacraments “effect what they figure”—that is, they are more than mere signs of grace; and yet, they also maintained that they are not proper causes of grace in the way fire is the proper cause of heat. One way to reconcile these requirements is to explicate sacramental causation in terms of sine qua non causes, which were distinguished from accidental causes on the one hand, and from proper efficient causes on the other hand. (...) This article traces the development of this concept, as discussed in the context of the sacraments, from Scotus and Auriol, via Ockham and Peter of Ailly, to Gabriel Biel. It shows how the discussion, in its later stages, opened up concerns about occasionalism, offering thereby a case study of how particular theological issues led to metaphysical ones in the fourteenth and fifteenth centuries.

Even though theistic philosophers and scientists agree that God created, sustains, and providentially governs the physical universe and even though much has been published in general regarding divine action, what is needed is a fine-grained, conceptually coherent account of divine action, causation, dispositions, and laws of nature consistent with divine aseity, satisfying the widely recognized adequacy conditions for any account of dispositions.1 Such an account would be a basic part of a more comprehensive theory of divine action in relation to (...) the fundamental concepts of science and of mathematics. Our aim in this article is simply to present such a theory. (shrink)

Today’s debates present ”occasionalism’ as the position that any satisfying account of divine action must avoid. In this paper I discuss how a leading Cartesian author of the end of the seventeenth century, Pierre-Sylvain Régis, attempted to avoid occasionalism. Régis’s case is illuminating because it stresses both the difficulties connected with the traditional alternatives to occasionalism and also those aspects embedded in the occasionalist position that should be taken into due account. The paper focuses on Régis’s own account of secondary (...) causation in order to show how the challenge of avoiding occasionalism can lead to the development of new accounts of divine action.

In this paper I examine G. W. Leibniz’s view on the debate between occasionalists, mere conservationists, and concurrentists. Although commentators agree that Leibniz wants to reject occasionalism and mere conservationism, there is considerable disagreement about whether Leibniz is committed to a theory of divine concurrence that differs from occasionalism and mere conservationism in principled ways. I critically assess three interpretations of Leibniz’s theory in this paper. The first two (those of Robert Adams and Sukjae Lee) differ with respect to important (...) details, but they both assume that Leibniz straightforwardly affirms the continual creation doctrine. I argue that a coherent Leibnizian theory of divine concurrence cannot be constructed on the ontological framework that the continual creation doctrine provides. The third interpretation that I consider holds that Leibniz is willing to affirm the continual creation doctrine only to the extent that it provides an acceptable way of characterizing the dependence of finite substances on God at the level of appearances. It is suggested that Leibniz’s deep metaphysical view of creation and conservation is that in a single act God creates and conserves substances that are non‐spatial and atemporal at the deepest level of metaphysical rigor. I argue that this alternative account of creation and conservation provides a promising ontological framework that can support a coherent theory of creaturely activity that does not collapse into occasionalism or mere conservationism.

According to most medieval thinkers, whenever something causally acts on another thing, God also acts with it. Durand of St.-Pourçain, an early fourteenth-century Dominican philosopher, disagrees. This paper is about a fourteenth-century objection to Durand’s view, which I will call the Fiery Furnace Objection, as formulated by Durand’s contemporary, Peter of Palude. Although Peter of Palude is not usu- ally regarded as a particularly original thinker, this paper calls attention to one of his more interesting controversies with his fellow friar, (...) while it also clarifies how some medieval thinkers understood the broadly speaking Aristotelian conviction that causes and effects are necessarily related. (shrink)

The paper deals with the problem of divine causation in relation to created agents in general and human rational agents in particular. Beyond creation and conservation, Aquinas specifies divine contribution to created agents’ operation as application in the role of the first cause and the operation of the principal cause employing an instrumental cause. It is especially the latter which is open to varying interpretation and which might be potentially threatening to human freedom. There are different readings of what it (...) is for the secondary agent to “act through the power of the principal cause”. Either the divine cause causes only the existence of the effect of the secondary cause, or it also causes the cause to operate in the sense that it determines its outcome. The latter seems to contradict human freedom. Both readings of Aquinas were developed in the latter half of the sixteenth century within scholastic philosophy and theology. (shrink)

In this paper, I investigate Louis de La Forge's argument against body–body causation. His general strategy exploits the impossibility of bodies communicating their movement by transfer of motion. I call this the ‘non-transfer’ argument . NT allows La Forge both to reinterpret continuous creation in an occasionalistic fashion and to support his non-occasionalistic view concerning mind–body union. First, I present how NT emerges in Descartes’ own texts. Second, I show how La Forge recasts it to draw an occasionalistic account of (...) body–body interactions, and I discuss how La Forge supports NT with continuous creation. Third, I conclude by suggesting that this further step of his argument does not undermine his non-occasionalistic account of mind–body union. (shrink)
