Much early modern metaphysics grew with an eye to the new science of its time, but few figures took it as seriously as Emilie du Châtelet. Happily, her oeuvre is now attracting close, renewed attention, and so the time is ripe for looking into her metaphysical foundation for empirical theory. Accordingly, I move here to do just that. I establish two conclusions. First, du Châtelet's basic metaphysics is a robust realism. Idealist strands, while they exist, are confined to non-basic regimes. (...) Second, her substance realism seems internally coherent, so her foundational project appears successful.I have two aims in this paper. Historically, I show that du Châtelet's main source of inspiration was Christian... (shrink)

This book evaluates the widespread preference in philosophy of mind for varieties of property dualism over other alternatives to physicalism. It takes the standard motivations for property dualism as a starting point and argues that these lead directly to nonphysical substances resembling the soul of traditional metaphysics. In the first half of the book, the author clarifies what is at issue in the choice between theories that posit nonphysical properties only and those that posit nonphysical substances. The crucial question, he (...) argues, is whether one posits nonphysical things that satisfy an Aristotelian-Cartesian independence definition of substance: nonphysical things that could exist in the absence of anything else. In the second half, the author argues that standard and Russellian monist forms of property dualism are far less plausible than we usually suppose. Most significantly, the presuppositions of one of the leading arguments for property dualism, the conceivability argument, lead by parity of reasoning to the view that conscious subjects are nonphysical substances. He concludes that if you posit nonphysical properties in response to the mind-body problem then you should be prepared to posit nonphysical substances as well. Mainstream philosophy of mind must take nonphysical substances far more seriously than it has done for the best part of a century. The Mind-Body Problem and Metaphysics will be of interest to scholars and advanced students working in philosophy of mind, metaphysics, and the history of philosophy. (shrink)

This article aims to review the standard objections to dualism and to argue that will either fail to convince someone committed to dualism or are flawed on independent grounds. I begin by presenting the taxonomy of metaphysical positions on concrete particulars as they relate to the dispute between materialists and dualists, and in particular substance dualism is defined. In the first section, several kinds of substance dualism are distinguished and the relevant varieties of this kind of dualism are (...) selected. The remaining sections are analyses of the standard objections to substance dualism : It is uninformative, has troubles accounting for soul individuation, causal pairing and interaction, violates laws of physics, is made implausible by the development of neuroscience and it postulates entities beyond necessity. I conclude that none of these objections is successful. (shrink)

Twenty years before Suárez’s Metaphysicae disputationes, Pedro da Fonseca offered one of the most impressive modern attempts to reorder Aristotle’s Metaphysics. In the present chapter, I will endeavour to show how insightful Fonseca’s effort truly was, by dealing with his ousiology. I will focus especially on the Jesuit’s account of three pivotal concepts in the scholastic theory of substance, i.e. Divine Substance, created substance and prime substance, or supposit. These notions are primarily metaphysical, but — according (...) to a long-standing scholastic framework — are also deeply indebted to Patristic Trinitarianism. As I shall argue, this is especially true for Fonseca, who welcomes and defends the idea of a conceptual unity between ontology, ousiology and Trinitarism he received from a centuries-long tradition.

The historical development of the understanding of water is traced in the light of the development of the general concept of chemical substance. From the times of the earliest known ancient Greek philosophers, water has played a central role in the conception of the material constitution of the world. But it was Aristotle who developed the most sophisticated understanding of water to have come down to us from the ancients. He viewed it as part of an intricate and systematic (...) theory of chemical substance, which classified water as an element along with earth, fire and air. His view exerted a considerable influence on Arabic and European thinkers throughout the Middle Ages, and wasn’t successfully challenged until the eighteenth century. After Lavoisier, it was recognised that water, though unlike air a single substance and not a mixture, is neither an element nor always liquid. General features of chemical substances, distinguishing elements, compounds and mixtures, were elaborated in a general theory and harmonised with the mechanical features of matter towards the end of the nineteenth century. Finally, the continuous conception of matter underlying the Aristotelian view, which had been unsuccessfully challenged in the seventeenth century, was definitely overturned in the twentieth century, and the intricate microstructure of water was revealed.

ABSTRACTMaterialism is the view that everything that is real is material or is the product of material processes. It tends to take either a ‘cosmological’ form, as a claim about the ultimate nature of the world, or a more specific ‘psychological’ form, detailing how mental processes are brain processes. I focus on the second, psychological or cerebral form of materialism. In the mid-to-late eighteenth century, the French materialist philosopher Denis Diderot was one of the first to notice that any self-respecting (...) materialist had to address the question of the status and functional role of the brain, and its relation to our mental life. After this the topic grew stale, with knee-jerk reiterations of ‘psychophysical identity’ in the nineteenth-century, and equally rigid assertions of anti-materialism. In 1960s philosophy of mind, brain–mind materialism reemerged as ‘identity theory’, focusing on the identity between mental processes and cerebral processes. In contrast, Diderot’s cerebral materialism allows for a more culturally sedimented sense of the brain, which he described in his late Elements of Physiology as a ‘book – except it is a book which reads itself’. Diderot thus provides a lesson for materialism as it reflects on the status of the brain, science and culture. (shrink)

Ayahuasca is a psychedelic beverage from the Amazon rainforest, used in spiritual and religious settings for medical purposes. Since the 1990s onwards, several religious and neo‐shamanic groups have been using it in Uruguay within the psychospiritual networks. Some participants go to rituals of ayahuasca looking for therapeutic alternatives to certain ailments, such as substance use disorders (SUDs). In this chapter, three cases of former patients who recovered in a neo‐shamanic center that uses ayahuasca for the treatment of SUDs are (...) described and analyzed. The center is conducted by a psychologist trained in the Peruvian vegetalismo tradition. An ethnographic description of the ritual setting as well as the process of psychotherapeutic intervention of the center are described. In‐depth interviews were used to collect the narratives of the three patients. A medical anthropology perspective is used, focusing on different subjective trajectories: the general biographic trajectory, SUDs trajectory, spiritual trajectory, and the trajectory under the entheogenic field, ayahuasca included. As we discuss, the impact of ayahuasca rituals ceremonies should be explained not only by ayahuasca as a psychedelic compound, but as a psychotherapeutic tool immersed in a social, cultural, and spiritual setting aimed at the treatment of SUDs.

In the early modern period one can find unity of consciousness arguments in the writings of Rene Descartes and G. W. Leibniz, and in the recent literature they have been defended by David Barnett, William Hasker, and Richard Swinburne (among others). Descartes's unity of consciousness argument for dualism is to be found in the sixth of his Meditations on First Philosophy. Descartes claims that his unity of consciousness argument was itself sufficient to establish substance dualism. Swinburne's central line of (...) argument involves deploying a number of puzzle cases. He argues that our intuitions about these cases can be accommodated only by adopting a “further fact” view of the self, according to which the continued existence of a person over time consists in the continued existence of a mental substance, and “it is metaphysically possible that the substance acquires a totally new body, totally new apparent memories, and character”.

This paper presents a moral argument in support of the view that the mind is a nonphysical object. It is intuitively obvious that we, the bearers of conscious experiences, have an inherent value that is not reducible to the value of our conscious experiences. It remains intuitively obvious that we have inherent value even when we represent ourselves to have no physical bodies whatsoever. Given certain assumptions about morality and moral intuitions, this implies that the bearers of conscious experiences—the objects (...) possessing inherent value—are not physical objects. This moral evidence is corroborated by introspective evidence. (shrink)

Is the self a substance, as Descartes thought, or is it 'only' a bundle of perceptions, as Hume thought ? In this paper I will examine these two views, especially with respect to two central features that have played a central role in the discussion, both of which can be quickly and usefully explained if one puts them as an objection to the bundle view. First, friends of the substance view have insisted that only if one conceives of (...) the self as a substance is it possible to account for genuine particularity of selves and genuine persistence through time of them. I will discuss in detail this claim as well as a special case of persistence - the case of a fission of a self - and I will ask, as Shoemaker (1997) did, how such a case can be handled by the two competing theories. The second central point of traditional disagreement concerns independence : it is often said that only a substance, but not a mere bundle, is independent enough of its properties to play properly the role of a self, and I will have something to say about this. Concerning all these points, my thesis will be a meta-theoretical one : contrary to appearances, both views can accommodate all of them (particularity at a time, persistence, fission, independence) in the same way, and I will examine two possible conclusions to be drawn from this : either that the differences between the two views are no more than terminological and that they turn out to be equivalent views, or that the differences are metaphysical but that it is epistemically under-determined which one of the views we should choose.

The aim of this article is to clarify an aspect of Descartes’s conception of mind that seriously impacts on the standard objections against Cartesian dualism. By a close reading of Descartes’s writings on imagination, I argue that the capacity to imagine does not inhere as a mode in the mind itself, but only in the embodied mind, that is, a mind that is not united to the body does not possess the faculty to imagine. As a mode considered as a (...) general property, and not as an instance of it, belongs to the essence of the substance, and as imagination (like sensation) arises from the mind-body union, then the problem arises of knowing to what extent a Cartesian embodied mind is separable from the body.

In this paper I present Suárez’s conception on material substance in connection with two main aspects of his theory. The first aspect is “reification” of the intrinsic principles of a composite, which has led some interpreters to the claim that Suárez significantly prepared the way for the accession of Cartesian anthropological dualism. The second one is Suárez’s emphasis on the substantial unity of material composites. The analysis of the second aspect is conceived as a counterbalance to some uncharitable interpretations (...) of Suárez’s hylemorphism. In the second part of the paper the relevance of Suárez’s arguments to contemporary debates on the ontological constitution of individuals is presented. (shrink)

This article examines the role of anecdote and casual literary criticism in the post-Tang defamation of Han Yu’s character. Several scholar-officials from the Song, Yuan, and later eras criticized Han Yu’s moral inconsistency in their collections of “miscellaneous notes” and “remarks on poetry”. Specifically, Han Yu is condemned for over-indulging in amorous relations with young female musicians and for pursuing immortality through alchemical means. I discuss the critical reception of a few key compositions authored by Han Yu and his contemporaries (...) in order to place his alleged activities in their historical context, explore the contested process by which he became a cultural icon, and clarify the various ways that later literati shaped his image and used it for their own purposes.

This commentary provides a legal analysis of the extent to which changes proposed by scholars to promote care for substance use disorder or other under-treated illnesses through risk adjustment could be implemented administratively, without legislation, in federal risk adjustment systems: Medicare's privatized component, Medicare's pharmaceutical component, and the individual and small group market. As the article explains, federal laws governing risk adjustment provide broad discretion to regulators and can reasonably be interpreted to permit full and final implementation through the (...) administrative process of almost all of the changes that scholars have proposed.

Avicenna's analysis of the definition of substance and accident repeatedly emphasizes two points: one and the same essence cannot be substance in one instance and accident in another; whetherxis extrinsic or intrinsic for an underlying subject,ydoes not tell us anything as to whetherxis substance or not. Both points are development in an argument against certain unnamed people who claimed the opposite. In this article I will show that Avicenna's opponents are to be identified with the mainstream Baghdad (...) Peripatetic School which based itself on the Late Antique rule that “parts of substances are substances”. As for Avicenna's own position, it was developed on the basis of the heterodox position of Yaḥyā b. ʿAdī, who anticipated Avicenna's first point. This is a further piece of evidence for something that has only recently begun to be appreciated: the influence of Ibn ʿAdī on Avicenna.RésuméL’analyse d’Avicenne portant sur les définitions de la substance et de l’accident met en exergue les deux propositions suivantes: 1) la même essence ne peut être à la fois une substance dans un cas et un accident dans un autre; 2) le fait quexsoit extrinsèque ou intrinsèque à unysous-jacent ne nous permet pas de conclure quexest une substance. Ces deux propositions sont articulées dans un débat avec d’autres personnes ayant un point de vue opposé dont on ne connaît pas l’identité. Dans cet article, nous verrons que ces adversaires font partie de l’école péripatétique de Bagdad, qui elle-même s’appuie sur une proposition datant de l’Antiquité tardive et selon laquelle les parties de substances sont elles-mêmes des substances. La position d’Avicenne fut développée à partir de celle de Yaḥyā b. ʿAdī. Cet article apporte ainsi un argument nouveau qui met en évidence l’influence, remarquée seulement depuis peu, d’Ibn ʿAdī sur Avicenne. (shrink)

ABSTRACTThe most prominent early modern argument against materialism is to be found in Descartes. Previously I had argued that this argument relies crucially on a robust conception of substance, according to which it has a single principal attribute of which all its other intrinsic qualities are modes. In the present paper I return to this claim. In Section 2, I address a question that is often raised about that conception of substance: its commitment to the idea that a (...) substance has a single such principal attribute. Gonzalo Rodriguez-Pereyra and Daniel Garber have argued that this claim relies on Descartes's identification of substance with attribute. But I argue that it relies on his view that a substance has a single, unitary nature. In Section 3, I examine the role of this conception of substance in arguments found in Malebranche and Leibniz and compare these arguments with Descartes's. (shrink)

I argue in this essay that Richard Swinburne’s revised version of Descartes’ argument in chapter 5 of his Are We Bodies or Souls? does not quite get him to the conclusion that he requires, but that a modified version of his treatment of personal identity will do the trick. I will also look critically at his argument against epiphenomenalism, where, once again, I share his conclusion but have reservations about the argument.

In the course of developing his theory of what would now be called chemical substance, Aristotle introduces what appear to be two distinct definitions of element alongside his notion of mixt (homogeneous mixture). The present paper is concerned with the integration of these ideas in a uniform theory, which calls for some speculation about the import of elemental proportions in compounds.

In the last decade, there has been a notable upsurge in property (PD) and generic substance dualism (SD). By SD I mean the view that there is a spiritual substantial soul that is different from but variously related to its body. SD includes Cartesian, certain forms of late Medieval hylomorphic (e.g., Aquinas'), and Haskerian emergent SD. Nevertheless, some form of physicalism remains the majority view in philosophy of mind. Several fairly standard objections have been raised against SD, and SDists (...) have been preoccupied with these objections. As a result, a potent objection has not been given the attention it deserves. The purpose of this article is to fill that lacuna by raising the visibility of this objection and providing plausible responses to it. First, I shall clarify the explanatory–impotence challenge and, second, provide defeaters against it. Note that several of the issues to follow apply both to PD and SD. I will focus mostly on SD, but sometimes PD is a part of the discussion in that certain arguments for and against PD indirectly affect SD. When it is important for me to note that either SD or PD is specifically being addressed, I will notify the reader. (shrink)

We will focus on the theory of complete concept in the philosophy of Leib-niz. We will not emphasise the epistemological aspects, but rather will concentrate on the metaphysical implications of this theory. Some questions requiring an answer will be: are there two individual substances of the same kind? What is the nature of a substance that is only possible? What kind of notion has the unactualised possible? What is the nature of the relationship between individual substance and the (...) complete no-tion? In order to answer these questions, we will present in the first part of the paper the concept of individual substance, in the second part, we will focus on the problem whether the possible objects have or have not a complete concept, and in the third part we will give some additional arguments to support our answer.

Jēkabs Osis (1860–1920) is the first academically educated Latvian philosopher and one of the founders of the University of Latvia. However, Osis never worked there. His academic life was closely tied with the University of Tartu, where he studied theology, philosophy and eventually became a professor of philosophy. Inspired by his mentor, professor of philosophy, Gustav Teichmüller, Osis turned his attention to the works of Leibniz, most notably those about the nature of substance. Osis aspired to unify the understanding (...) of the notion of substance with the necessity to substantiate the immortality of individual entities. Osis criticized the philosophy of Leibniz and verified a new understanding of substance that is found in the works of Teichmüller. (shrink)

This paper develops a valid reconstruction in first-order predicate logic of Leibniz’s argument for his complete concept definition of substance in §8 of the Discours de Métaphysique. Following G. Rodriguez-Pereyra, it construes the argument as resting on two substantial premises, the “merely verbal” Aristotelian definition and Leibniz’s concept containment theory of truth, and it understands the resulting “real” definition as saying not that an entity is a substance iff its complete concept contains every predicate of that entity, but (...) iff its complete concept contains every predicate of any subject to which that concept is truly attributable. An account is suggested of why Leibniz criticises the Aristotelian definition as merely nominal and how he takes his own definition to overcome this shortcoming: while on the Aristotelian basis the predication relation could generate endless chains, so that substances as endpoints of predication would be impossible, Leibniz’s definition reveals lowest species as such endpoints, which he therefore identifies with individual substances. Since duplicate lowest species make no sense, the Identity of Indiscernibles for substances follows. The reading suggests a Platonist interpretation according to which substances do not so much have but are individual essences, natures or forms. (shrink)

This essay offers an alternative account of Leibniz’s views on substance and fundamental ontology. The proposal is driven by three main ideas. First, that Leibniz’s treatment should be understood against the backdrop of a traditional dispute over the paradigmatic nature substance as well as his own overarching conciliatory ambitions. Second, that Leibniz’s metaphysics is intended to support his conciliatory view that both traditional views of substance are tenable in at least their positive and philosophical respects. Third, that (...) the relationship between immaterial substances, corporeal substances, and ordinary bodies in Leibniz’s metaphysics is best understood as one of “material” constitution. The interpretation as a whole thus suggests that Leibniz needn’t be read as offering either an exclusive defense of corporeal substance realism, nor of immaterial substance idealism, nor as being deeply torn (at a time or over time) between two such views. He may instead be seen as offering a carefully presented, consistent, and sophisticated conciliatory account of substance. (shrink)

At the opening of Spinoza’s Ethics, we find the three celebrated definitions of substance, attribute, and God: E1d3: By substance I understand what is in itself and is conceived through itself, i.e., that whose concept does not require the concept of another thing, from which it must be formed [Per substantiam intelligo id quod in se est et per se concipitur; hoc est id cujus conceptus non indiget conceptu alterius rei, a quo formari debeat]. E1d4: By attribute I (...) understand what the intellect perceives of a substance, as constituting its essence [Per attributum intelligo id, quod intellectus de substantia percipit, tanquam ejusdem essentiam constituens]. E1d6: By God I understand a being absolutely infinite, that is, a substance consisting of an infinity of attributes, of which each one expresses an eternal and infinite essence We are accustomed to think of these paramount definitions as a fixed and settled formulation of the core of Spinoza’s metaphysics, but if we look at the development of Spinoza’s thought, the picture we get is quite different. In the early drafts of the Ethics and in his early works, Spinoza seems to have experimented with various conceptualizations of the relations between substance, attribute, and God. Some of Spinoza’s works make barely any use of the notions of substance and attribute, and the testimony of Spinoza’s letters suggests that, at a certain stage in his philosophical development, the concept of attribute may have been put on the back burner, if not completely dropped. Indeed, another closely related concept—accident [accidens]—was fated to be pulled out of the system (and for good reasons ). The final version of the Ethics makes hardly any use of this notion, but Spinoza’s letters show that in early drafts of the Ethics he used the term ‘accident’ to refer to what cannot be or be conceived without substance. In this paper I will attempt to provide a brief outline of the genealogy of Spinoza’s key metaphysical concepts. This genealogy, like any other, can help us to reexamine and reconsider what seems to us natural, stable and obvious. In the first part of the paper, I rely on Spinoza’s letters to trace the development of his definitions of substance and attribute in the early drafts of the Ethics. The letters, whose dates are more or less established, also provide a temporal grid for our subsequent discussions. The second part surveys Spinoza’s discussion and conceptualization of substance and attributes in the Treatise on the Emendation of the Intellect, the Theological-Political Treatise (1670), and briefly, Spinoza’s 1663 book on Descartes’ Principles of Philosophy, and its appendix on Metaphysical Thoughts, the Cogitata Metaphysica. The third part of the paper is dedicated to Spinoza’s understanding of substance and attribute in the Short Treatise on God, Man, and His Well-Being. I conclude with some remarks on the stability of Spinoza’s final position on the issue, as expressed in the published version of the Ethics . (shrink)

Jin Qian Dans son Discours sur la théologie naturelle des Chinois, Leibniz produit une interprétation du premier principe de la philosophie chinoise. Le présent article s’interroge sur les conditions de cette interprétation en la comparant avec la controverse entre Leibniz et Descartes par rapport à la conception de la substance. Il sera montré que, bien que Leibniz utilise un « principe herméneutique » dans son interprétation de la philosophie chinoise, ce principe n’est pas suffisant mais repose sur des conditions (...) plus fondamentales. La comparaison avec la controverse Leibniz-Descartes sur la substance permet d’identifier deux conditions majeures de l’application de ce principe herméneutique, à savoir la théorie dynamique de la substance et la conception de la théologie naturelle comme fondement de la physique, deux points sur lesquels divergent Leibniz et Descartes.

The paper examines Wright’s attempt to inflate deflationism about truth. It accepts the details of Wright’s argument but contends that it should best be seen as posing a dilemma for the deflationist: either truth is independent of norms of warranted assertibility—in which case it is substantial—or it is not—in which case epistemicism about truth is a consequence. Some concerns about epistemicism are raised in avoiding the second horn. The first is avoided by distinguishing between independence and substantiality and arguing that (...) only the first applies to truth and only the second is worrisome to deflationism. So, despite its sub-title, the following is not a diatribe against Home Rule but a modest defence of deflationism. (shrink)

Despite extinction-based processes demonstrating efficacy in the animal extinction and human anxiety literatures, extinction for substance use disorders has shown poor efficacy. Reasons for this lack of success include common threats to extinction, such as renewal and reinstatement. In recent decades, research on mindfulness for SUD has flourished, and a key aspect of these mindfulness-based interventions includes teaching individuals to stay present with whatever experience they have, even if unpleasant, without trying to change/escape/avoid it. Similarly, CET teaches individuals to (...) not escape/avoid conditioned responses by engaging in drug use behavior. This paper discusses how mindfulness-based research and practices could positively influence CET through future research, with the long-term goal of improving SUD treatment. (shrink)

This paper poses a dilemma for applying the category of substance given Kant's different conceptions of substance in the Critique of Pure Reason. Briefly stated, if the category of substance applies to an omnipresent and sempiternal substance, then although this would ensure that all experiences of empirical objects take place in a common spatiotemporal framework, one could not individuate these empirical objects and experience their alterations. If the category of substance applies to ordinary empirical objects, (...) however, then although one could individuate these substances and experience their alterations, the category would not pick out a common spatiotemporal framework for these experiences. I will argue that this dilemma can be overcome by examining the development of Kant's conception of substance in his final work, the Opus postumum. (shrink)
