The paper focuses on Priestley’s complex views on the essence of God in connection with his materialism, elaborated in the Disquisitions Relating to Matter and Spirit (1777/ 1782). This issue is crucial if one wishes to get a clear idea of what Priestley’s materialism amounts to; whether it is mainly a thesis about the material grounds of the human mind (“psychological materialism”), or a more far-reaching one about what kind of substances exist in the world (a version of “ontological materialism”). (...) The claim that God may be material allows for the most radical version of ontological materialism according to which everything in the world is material, without altogether denying that God exists. In fact, Priestley considers and partially defends at least three different views on the potential materiality of God: (1) an agnostic stance that is his official view, (2) materialism about God based on his own theory of matter, and (3) “gross” materialism about God. The aim of the paper is to analyze these three views, in particular concerning what kind of materialism they support and whether they can contribute to the consistent Christian materialism Priestley envisaged.

The article analyses recent English publications in Cartesian studies that deal with two problems: the problem of the intrinsic coherence of Descartes’s doctrine of the real distinction and interaction between mind and body and the problem of the consistency of this doctrine with the causal principle formulated in the Third Meditation. The principle at issue is alternatively interpreted by different Cartesian scholars either as the Hierarchy Principle, that the cause should be at least as perfect as its effects, or the (...) Containment Principle, that the cause should contain all there is in its effects. The author argues that Descartes’s claim that it is inconceivable how things of different natures can interact does not conflict with the acknowledgement of interaction between things of different natures in the case of soul and body. The case is made that Cartesian mind-body interaction can agree with both the Hierarchy Principle and the Containment Principle, because the Principle is about total and efficient cause, whereas in the interaction, mental and brain states are only partial causes. In particular, in the case of the causality in the brain-to-mind direction, the mind is conditioned by brain states to form the corresponding specific ideas on the basis of its innate general ideas of movements, forms, colours, etc. Eventually, for Descartes, the most natural way to deal with worries about the possibility of mind-brain interaction is to rely on God’s omnipotence, which certainly enables Him to arrange for such interaction.

Descartes notoriously characterizes substance in two ways: first, as an ultimate subject of properties ; second, as an independent entity. The characterizations have appeared to many to diverge on the definition as well as the scope of the notion of substance. For it is often thought that the ultimate subject of properties need not—and, in some cases, cannot—be independent. Drawing on a suite of historical, textual, and philosophical considerations, this essay argues for an interpretation that reconciles Descartes's two characterizations. It (...) proposes that both characterizations invoke a type of independence that obtains just in case there is no relation to another entity that holds by the nature of the entity in question. Even though the ultimate subject of properties is sometimes not independent in other respects, it satisfies this independence-by-nature condition. (shrink)

It is a matter of continuing scholarly dispute whether Descartes offers a metaphysics of the material world that is “monist” or “pluralist.” One passage that has become crucial to this debate is from the Synopsis of the Meditations, in which Descartes argues that since “body taken in general” is a substance, and since all substances are “by their nature incorruptible,” this sort of body is incorruptible as well. In this article I defend a pluralist reading of this passage, according to (...) which there are indefinitely many bodies-taken-in-general, each of which counts as an incorruptible material substance. However, I also consider some surprising features of the argument in the Synopsis. One is that this argument conflicts with the implication in Descartes that any two “really distinct” substances can each exist without the other existing. Another is that the argument tends to undermine his suggestion that there is room at a fundamental metaphysical level for ordinary material objects. (shrink)

ArgumentThis paper argues that Samuel Clarke's account of agent causation (i) provides a philosophical basis for moderate voluntarism, and (ii) both leads to and benefits from the acceptance of partial occasionalism as a model of causation for material beings. Clarke's account of agent causation entails that for an agent to be properly called an agent (i.e. causally efficacious), it is essential that the agent is free to choose whether to act or not. This freedom is compatible with the existence of (...) conceptually necessary connections. Hence, Clarke can harmonize God's freedom of choosing with the existence of eternal and necessary relations among things. Moreover, in Clarke's account, only intelligent entities can be properly understood as efficacious causes. Beings deprived of intelligence are not agents or efficacious causes at all and their effects are thus the result of the immediate action of some intelligent being operating upon them. (shrink)

The goal of this article is to suggest that in early modern discussions of agency and causal efficacy it is possible to detect an attempt at pushing to its extreme consequences a specific account of agency and causality that was developed in late scholastic thought. More specifically, the article examines Francisco Suárez's (1548–1617) account of freedom and how this relates to his views on efficient causality. Despite Suárez's careful way of differentiating between natural (necessary) and human (free) agents, his view (...) can be exploited to drive home occasionalist positions that deny causal efficacy for natural agents lacking reason. The family resemblance that might be noted between early modern positions could be traced back to the reception of a common late scholastic background and to the tensions and potential nestled there.

The conservation of energy and momentum have been viewed as undermining Cartesian mental causation since the 1690s. Modern discussions of the topic tend to use mid-nineteenth century physics, neglecting both locality and Noether’s theorem and its converse. The relevance of General Relativity has rarely been considered. But a few authors have proposed that the non-localizability of gravitational energy and consequent lack of physically meaningful local conservation laws answers the conservation objection to mental causation: conservation already fails in GR, so there (...) is nothing for minds to violate. This paper is motivated by two ideas. First, one might take seriously the fact that GR formally has an infinity of rigid symmetries of the action and hence, by Noether’s first theorem, an infinity of conserved energies-momenta. Second, Sean Carroll has asked how one should modify the Dirac–Maxwell–Einstein equations to describe mental causation. This paper uses the generalized Bianchi identities to show that General Relativity tends to exclude, not facilitate, such Cartesian mental causation. In the simplest case, Cartesian mental influence must be spatio-temporally constant, and hence 0. The difficulty may diminish for more complicated models. Its persuasiveness is also affected by larger world-view considerations. The new general relativistic objection provides some support for realism about gravitational energy-momentum in GR. Such realism also might help to answer an objection to theories of causation involving conserved quantities, because energies-momenta would be conserved even in GR. (shrink)

Misconceptions about energy conservation abound due to the gap between physics and secondary school chemistry. This paper surveys this difference and its relevance to the 1690s–2010s Leibnizian argument that mind-body interaction is impossible due to conservation laws. Justifications for energy conservation are partly empirical, such as Joule’s paddle wheel experiment, and partly theoretical, such as Lagrange’s statement in 1811 that energy is conserved if the potential energy does not depend on time. In 1918 Noether generalized results like Lagrange’s and proved (...) a converse: symmetries imply conservation laws and vice versa. Conservation holds if and only if nature is uniform. The rise of field physics during the 1860s–1920s implied that energy is located in particular places and conservation is primordially local: energy cannot disappear in Cambridge and reappear in Lincoln instantaneously or later; neither can it simply disappear in Cambridge or simply appear in Lincoln. A global conservation law can be inferred in some circumstances. Einstein’s General Relativity, which stimulated Noether’s work, is another source of difficulty for conservation laws. As is too rarely realized, the theory admits conserved quantities due to symmetries of the Lagrangian, like other theories. Indeed General Relativity has more symmetries and hence more conserved energies. An argument akin to Leibniz’s finally gets some force. While the mathematics is too advanced for secondary school, the ideas that conservation is tied to uniformities of nature and that energy is in particular places, are accessible. Improved science teaching would serve the truth and enhance the social credibility of science. (shrink)

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)

Widespread scholarly agreement has it that Descartes' theory of judgment favors a compatibilist interpretation. This essay explains and rebuts the standard arguments made on behalf of compatibilist readings, while explaining and defending a libertarian interpretation. Along with relevant Fourth Meditation doctrines and texts, my analysis encompasses a much discussed 1645 letter discussing his account. Although some scholars view the letter as departing from the account of theMeditations, I argue that the two works present a consistent view – allowing us to (...) take at face value that the letter purports to elaborate Descartes' intended meaning in the associated Fourth Meditation passage.

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)

The notion that something can exist a se is central to Descartes’s overall metaphysics of causation. In the Meditations, divine aseity plays the role of explaining not only God’s existence but ultimately the existence of everything else apart from God. Yet in the Meditations proper, as well as in the early Replies, Descartes does little to clarify exactly what his view of divine aseity is and how it might differ from the sort of aseity commonly posited by the Scholastics. Despite (...) Descartes’s later attempts to assuage this worry and clarify his position, the positive aseity charge has not gone away. Here I shall argue that the charge is unjustified on all counts. Baldly stated, Descartes’s notion of aseity is no different than the negative sense of aseity endorsed by his Scholastic predecessors - especially Aquinas. Understanding this not only helps in clarifying the overall picture of Cartesian causality but also aids in seeing how commentaries on the Meditations, old and new, have obscured it. (shrink)

This paper examines Aquinas's theory of dualist mental causation, that is, his theory of how human beings can efficiently cause changes in their bodies in virtue of two non-physical mental states of theirs, specifically an act of the intellect and an act of the will. It is first shown that Aquinas's hylomorphism does not lie at the heart of this theory. Rather, a relation that he calls “contact of power” (tactus virtutis) does. The remainder of the paper then investigates the (...) nature of this relation. Since Aquinas discusses key marks of it by contrasting it with physical contact, the paper focuses on this contrast. It is argued that, for Aquinas, the human soul stands in a relation of contact of power to the body or, more precisely, a certain part of the body when it causes a change in it and is holenmerically co-located with it.

In this paper, I explore René Descartes' conception of human freedom. I begin with the key interpretive challenges of Descartes' remarks and then turn to two foundational issues in the secondary literature: the philosophical backdrop of Descartes' remarks and the notions of freedom that commentators have used to characterize Descartes. The remainder of the paper is focused on the main current debate: Descartes' position on the relationship between freedom and determinism.

Scholars have long recognized that Newton regarded Descartes as his principal philosophical interlocutor when composing the first edition of Philosophiae Naturalis Principia Mathematica in 1687. The arguments in the Scholium on space and time, for instance, can profitably be interpreted as focusing on the conception of space and motion in part two of Descartes's Principles of Philosophy (1644). What is less well known, however, is that this Cartesian conception, along with Descartes's attempt to avoid Galileo's fate in 1633, serves as (...) an essential background to understanding Newton's own (poorly understood) view of the theological implications of his theory of space and motion. In particular, after withdrawing Le Monde from publication in 1633 because of its Copernican leanings, Descartes later introduced what some regard as a “fudge factor” into the theory of motion in the Principles: from an ordinary perspective the earth does move; but from a philosophical one, it does not. This background indicates the novelty and originality of Newton's own attempt to explicate how scriptural passages concerning the motions of the heavenly bodies can be reconciled with the philosophical views he developed during the 1680s. New evidence from archival sources and correspondence supports this argument, shedding light on the Scholium and on Newton's conception of philosophy's relation to theology. (shrink)

This paper compares Newton’s and Descartes’s conceptions of the complex relationship between physics and metaphysics.

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.

RESUMEN La interpretación habitual de Descartes sostiene que la nueva ciencia cartesiana es resultado del remplazo, en las explicaciones científicas, de las causas finales y formales por las causas eficientes. Si bien dicha afirmación en líneas generales es correcta, se ha tendido a asumir que las causas eficientes no entrañan problema alguno. Este artículo desea cuestionar dicha asunción, poniendo de manifiesto una serie de problemáticas concernientes a la cognoscibilidad de las causas eficientes. ABSTRACT The common interpretation of Descartes argues that (...) the new science is a result of Cartesian replacement, in scientific explanations, of the final and formal causes by the efficient causes. While this statement is broadly correct, it has tended to assume that efficient causes do not imply any problem. This paper wishes to question this assumption, showing a number of problems concerning the knowability of efficient causes. (shrink)

In this paper, I examine the manner in which Descartes defends his Vortex Hypothesis in Part III of the Principles of Philosophy, and expand on Ernan McMullin’s characterization of the methodology that Descartes uses to support his planetary system. McMullin illuminates the connection between the deductive method of Part III and the method Descartes uses in earlier portions of the Principles, and he brings needed light to the role that imaginative constructions play in Descartes’s explanations of the phenomena. I develop (...) McMullin’s reading by bringing further attention to the constraints that Descartes places on the imagination in Part III. I focus in particular on the way in which Descartes uses metaphysical truths concerning God’s nature to support his general description of the planetary system, and on the way he relies on a mathematical standard of intelligibility to defend his proposals about the configuration of matter. Attending to the role of metaphysics and mathematics in Part III shows that Descartes’s arguments for the explanatory power of the Vortex Hypothesis are more effective than McMullin suggests. The reading I forward also offers important perspective on how Descartes’s hypotheses in Part III can be seen as both metaphysically and mathematically well-grounded. (shrink)

It is a common view that Descartes' causal principle is to be understood in light of a similarity condition that accounts for how finite causes contribute to an explanation of their effects. This paper challenges this common view and offers a sui generis reading of Descartes' views on causation that has also the advantage of solving the two exegetical issues of whether Descartes thought of the body-to-mind relation in occasionalist or causal terms and of whether Descartes regarded sensory ideas innate (...) or caused by bodies.

This paper offers a novel interpretation of Descartes's conception of freedom that resolves an important tension at the heart of his view. It does so by appealing to the important but overlooked distinction between possessing a power, exercising a power, and being in a position to exercise a power.

Este artigo examina quais teorias da causalidade explicam a ocorrência de sentimentos em animais e homens, segundo Descartes. Esse exame é feito à luz do debate entre as teorias ocasionalista e interacionista, bem como da posição de Descartes nesse debate. Nesse contexto, são discutidas algumas objeções a essas teorias, buscando determinar em quais pontos Descartes poderia ser considerado um adepto de uma ou da outra. A hipótese defendida é a de que ele adota certos aspectos da teoria interacionista para explicar (...) a causalidade entre corpos, que caracteriza a ocorrência de sentimentos em animais. Por outro lado, ressalta-se o uso de duas linguagens em sua explicação da causalidade entre corpos humanos e mentes, que caracteriza os sentimentos humanos. Esse uso é explicado pelo fato de que, no caso desses sentimentos, ele adota uma posição que concilia ocasionalismo e interacionismo. (shrink)

Additive theories of rationality, as I use the term, are theories that hold that an account of our capacity to reflect on perceptually-given reasons for belief and desire-based reasons for action can begin with an account of what it is to perceive and desire, in terms that do not presuppose any connection to the capacity to reflect on reasons, and then can add an account of the capacity for rational reflection, conceived as an independent capacity to ‘monitor’ and ‘regulate’ our (...) believing-on-the-basis-of-perception and our acting-on-the-basis-of-desire. I show that a number of recent discussions of human rationality are committed to an additive approach, and I raise two difficulties for this approach, each analogous to a classic problem for Cartesian dualism. The interaction problem concerns how capacities conceived as intrinsically independent of the power of reason can interact with this power in what is intuitively the right way. The unity problem concerns how an additive theorist can explain a rational subject's entitlement to conceive of the animal whose perceptual and desiderative life he or she oversees as ‘I’ rather than ‘it’. I argue that these difficulties motivate a general skepticism about the additive approach, and I sketch an alternative, ‘transformative’ framework in which to think about the cognitive and practical capacities of a rational animal.

Descartes appears to hold that everything we believe is the product of a voluntary choice. Scholars have been reluctant to take this particularly radical version of doxastic voluntarism as Descartes’ considered position. I argue that once Descartes’ compatibilist conception of free will as well as his position on the ‘freedom of indifference’ are taken into account, the primary motivations for the rejection of the aforementioned radical version of doxastic voluntarism lose their force. Consequently, we may take Descartes at his word (...) when he maintains that everything we believe, we believe freely – even if we cannot believe anything we wish. (shrink)

Introduction The discussion of “self-knowledge” as a philosophical issue begins with an intuition. This intuition is based on the fact that our knowledge of our mental states or our knowledge in relation to statements like: “I know that I am happy,” is a particular knowledge that is distinct from the rest of our knowledge. It seems that in order to gain knowledge of ourselves, we do not need to go through those processes that we go through in order to gain (...) knowledge about the external world or knowledge of other minds. We feel that we directly know our own mental states. The role of self-knowledge philosophers is to explain this type of particular knowledge. Theories such as the Inner Sense Theory, the Acquaintance Theory, inferentialism, or theories with a rationalist approach are presented in response to this issue. Considering theories such as the Inner Sense Theory and the Acquaintance Theory, we will find that a common aspect of these theories is that self- knowledge has been defined as a product of an internal observation of our mental states. Such an approach is a kind of Empiricism in self-knowledge. The Rationalist approach has been raised against this approach. This approach, by linking self-knowledge with rationality, has opened a new chapter in the discussion of self-knowledge. The foundation of this approach is based on the principle that our situation as a rational agent plays a fundamental role in self-knowledge. Rationalists believed that this ignorance of the fundamental role of rationality in self-knowledge has caused Empiricists to ignore the most important kind of self-knowledge that is associated with rationality. Tyler Burge, Richard Moran, and Matthew Boyle are some of the important philosophers who theorize about this kind of self-knowledge. Goal In this paper, we will first introduce the main components of Rationalist approaches because we want to review the theoretical literature of this approach. Then, we will bring up a summary of the Tyler Burge view, a famous and important philosopher of the rationalist approach. This is an introduction to introduce Moran’s Theory of Transparency which is the focal point of our discussion. We will then refer to one of the most important challenges facing the Transparency Theory and bring up a significant solution that is presented by Matthew Boyle. We will also show that despite the advantages of this solution, there are ambiguities and other challenges. Finally, we will try to set up two proposals as a way to advance Boyle’s solution. Conclusion The perspective of rationalist philosophers about the existence of a kind of self-knowledge in rational creatures seems to be a powerful idea that is difficult to oppose. Tyler Burge presented interesting arguments about this issue. But it is not easy replying to the question of how this kind of self-knowledge occurs. The theory of Transparency and Reflectivism were proposed to respond to this question. Although they have been considered as efficient theories; however, the mentioned problem still remains ambiguous and complex. Transparency denied the introspective self-knowledge, but couldn’t explain how transparent self-knowledge occurs and therefore, it does not provide a complete explanation for self-knowledge. Some vagueness and some important challenges still continue to exist in this theory. Finally, we propose two proposals as a complement to Boyle’s theory. Maybe they could advance this theory. We suggest that we can use the concept of non-conceptual belief and dispositional belief. These debates have the potential for solving some of the challenges of Transparency and Reflectivism. These are profound topics and need great reflection. We know that our proposals are very elementary and crude ideas. But perhaps they can be a way toward developing the Transparency and Reflectivism theories. (shrink)

In his unpublished freewill manuscripts, Ralph Cudworth seeks to complete the project that he begins in The True Intellectual System of the Universe (1678) by arguing for an account of human liberty that avoids the opposing poles of necessitarianism and indifferency. I argue that Cudworth’s account rests upon a crucial distinction between the will and the power of freewill. Whereas we necessarily will the greater apparent good, freewill is a more fundamental power by which we endeavour to discern the greater (...) good before willing to pursue it. Cudworth thus opposes necessitarianism by arguing for a libertarian account of freewill while nonetheless rejecting the indifferentist claim that we can will contrary to the greater apparent good.

Descartes is usually taken to be a strict reductionist, and he frequently describes his work in reductionist terms. This dissertation, however, makes the case that he is a nonreductionist in certain areas of his philosophy and natural philosophy. This might seem like simple inconsistency, or a mismatch between Descartes's ambitions and his achievements. I argue that here it is more than that: nonreductionism is compatible with his wider commitments, and allowing for irreducibles increases the explanatory power of his system. Moreover, (...) Descartes depends on nonreductionist knowledge and on irreducibles in order to maintain his epistemology and metaphysics. That is, there is more in the Cartesian world than mind, matter, and God.
