This article explores the philosophical concept of akrasia, also known as weakness of will, and demonstrates its relevance to clinical practice. In particular, it challenges an implicit notion of control over one’s actions that might impede recovery from substance misuse. Reflecting on three fictional case vignettes, we show how philosophical work on akrasia helps avoid this potentially harmful notion of control by supporting a holistic engagement with people for whom substance misuse is a problem. We argue (...) that such engagement enhances their prospects of recovery by focusing on agency over time, as opposed to individual lapses. (shrink)

Recently, there have been calls to develop a more contextual approach to phenomenological psychopathology—an approach that attends to the socio-cultural as well as personal and biographical factors that shape experiences of mental illness. In this Perspective article, we argue that to develop this contextual approach, phenomenological psychopathology should adopt a new paradigm case. For decades, schizophrenia has served as the paradigmatic example of a condition that can be better understood through phenomenological investigation. And recent calls for a contextual approach continue (...) to use schizophrenia as their primary example. We argue, in contrast, that substance misuse provides a better paradigm case around which to develop a contextually sensitive phenomenological psychopathology. After providing a brief vignette and analysis of a case of substance misuse, we explain why this kind of condition requires considerable sensitivity and attention to context, better motivating the incorporation and development of new contextually sensitive approaches.

In this paper, I consider particular attempts by E. J. Lowe and Michael Gorman at providing an independence criterion of substancehood and argue that the stipulative exclusion of non-particulars and proper parts (or constituents) from such accounts raises difficult issues for their proponents. The results of the present discussion seem to indicate that, at least for the case of composite entities, a unity criterion of substancehood might have at least as much, and perhaps more, to offer than an independence criterion (...) and therefore ought to be explored further by neo-Aristotelians in search of a defensible notion of substancehood. I indicated briefly how such a unity criterion might be used by neo-Aristotelians to support the inclusion of hylomorphic compounds in the category of substance, given the traditional role of form as the principle of unity within the compound.

This paper is a study of Brentano’s ontology, and more specifically of his theory of substance and accident as put forward toward the end of his life in the materials collected together as the Kategorienlehre or Theory of Categories. Here Brentano presents an auditious (re-)interpretation of Aristotle’s theory of substance and accidence. We show that on the Brentano initially defends, it is space which serves as the single substance upon which all other entities depend as accidents of (...) space. In an appendix, however, Brentano puts forward an even more radical suggestion, inspired by the physics of Kelvin. According to this final view, space itself is an accident of a deeper substance: the present time. (shrink)

In this open peer commentary, we categorize the possible “neuroscience in national security” definitions of misuse of science and identify which, if any, are uniquely presented by advances in neuroscience. To define misuse, we first define what we would consider appropriate use: the application of reasonably safe and effective technology, based on valid and reliable scientific research, to serve a legitimate end. This definition presents distinct opportunities for assessing misuse: misuse is the application of invalid or (...) unreliable science, or is the use of reliable scientific methods to serve illegitimate ends. Ultimately, we conclude that while national security is often a politicized issue, assessing the state of scientific progress should not be. (shrink)

In my articles ‘The Substance View: A Critique’ and ‘The Substance View: A Critique,’ I raise objections to the substance view, a theory of intrinsic value and moral standing defended by a number of contemporary moral philosophers, including Robert P. George, Patrick Lee, Christopher Tollefsen, and Francis Beckwith. In part one of my critique of the substance view, I raise reductio-style objections to the substance view's conclusion that the standard human fetus has the same intrinsic (...) value and moral standing as the standard adult human being, among other human beings. In part two, I raise objections to some of the premises invoked in support of that conclusion. Here, in part three, I raise objections to Henrik Friberg-Fernros's attempt to rebut some of the aforementioned objections. (shrink)

In my initial critique of the substance view, I raised reductio-style objections to the substance view's conclusion that the standard human fetus has the same intrinsic value and moral standing as the standard adult human being, among others. In this follow-up critique, I raise objections to some of the premises invoked in support of this conclusion. I begin by briefly presenting the substance view as well as its defense. (For a more thorough presentation, see the first part (...) of my critique.) I then raise objections to three claims involved in the substance view's defense: the claim that the standard human fetus's intrinsic value and moral standing is a function of its potentiality; the claim that the standard human fetus's intrinsic value and moral standing is a function of its essential properties; and the claim that it is the possession of the basic potential for rational moral agency that best accounts for the wrongness of killing the standard human fetus, among others. (shrink)

According to the theory of intrinsic value and moral standing called the ‘substance view,’ what makes it prima facie seriously wrong to kill adult human beings, human infants, and even human fetuses is the possession of the essential property of the basic capacity for rational moral agency – a capacity for rational moral agency in root form and thereby not remotely exercisable. In this critique, I cover three distinct reductio charges directed at the substance view's conclusion that human (...) fetuses have the same intrinsic value and moral standing as adult human beings. After giving consideration to defenders of the substance view's replies to these charges, I then critique each of them, ultimately concluding that none is successful. Of course, in order to understand all of these things – the reductio charges, defenders of the substance view's replies to them, and my criticisms of their replies – one must have a better understanding of the substance view as well as its defense. Accordingly, I address the substance view's understanding of rational moral agency as well as present its defense. (shrink)

The *Tractatus* contains an argument that there are simple, necessarily existent objects, which, being simple, are suited to be the referents of the names occuring in the final analysis of propositions. The argument is perplexing in its own right, but also for its invocation of the notion of "substance". I argue that if one locates Wittgenstein's conception of substance in the Kantian tradition to which his talk of "substance" alludes, what emerges is an argument that is very (...) nearly--but not quite--cogent.

Purpose Prescription stimulant use as “cognitive enhancers” has been described among undergraduate college students. However, the use of prescription stimulants among future health care professionals is not well characterized. This study was designed to determine the prevalence of prescription stimulant misuse among students at an academic health sciences center. -/- Method Electronic surveys were e-mailed to 621 medical, pharmacy, and respiratory therapy students at East Tennessee State University for four consecutive weeks in fall 2011. Completing the survey was voluntary (...) and anonymous. Surveys asked about reasons for, frequency of, and side effects of nonprescription misuse of prescription stimulants. Given the sensitive material, an opportunity to win one of ten $50 gift cards was used as an incentive. -/- Results Three hundred seventy-two (59.9%) students completed the survey from three disciplines (47.6% medical, 70.5% pharmacy, and 57.6% respiratory therapy). Overall, 11.3% of responders admitted to misusing prescription stimulants. There was more misuse by respiratory therapy students, although this was not statistically significant (10.9% medicine, 9.7% pharmacy, 26.3% respiratory therapy; P = .087). Reasons for prescription stimulant misuse included to enhance alertness/ energy (65.9%), to improve academic performance (56.7%), to experiment (18.2%), and to use recreationally/get high (4.5%). -/- Conclusions Prescription stimulant misuse was prevalent among participating students, but further research is needed to describe prevalence among future health care workers more generally. The implications and consequences of such misuse require further study across professions with emphasis on investigating issues of academic dishonesty (e.g., “cognitive enhancement”), educational quality, and patient safety or health care quality.

Philosophers of mind typically conduct their discussions in terms of mental events, mental processes, mental properties, mental states – but rarely in terms of minds themselves. Sometimes this neglect is explicitly acknowledged. Donald Davidson, for example, writes that ‘there are no such things as minds, but people have mental properties, which is to say that certain psychological predicates are true of them. These properties are constantly changing, and such changes are mental events’.2 Hilary Putnam agrees, though for somewhat different reasons: (...) The view I have long defended is that the mind is not a thing; talk of our minds is talk of world-involving capabilities that we have and activities that we engage in. As Dewey succinctly put it, “Mind is primarily a verb. It denotes all the ways in which we deal consciously and expressly with the situation in which we find ourselves. Unfortunately, an influential manner of thinking has changed modes of action into an underlying substance that performs the activities in question. It has treated mind as an independent entity which attends, purposes, cares and remembers”. But the traditional view, by treating mental states as states of the “underlying substance”, makes them properties of something “inside”, and, if one is a materialist philosopher, that means properties of our brains. So the next problem naturally seems to be: “Which neurological properties of our brains do these mental properties ‘reduce’ to?” For how could our brains have properties that aren’t neurological? And this is how materialist philosophers saw the problem until the advent of such new alternatives in the philosophy of mind and philosophy of language as Functionalism and Semantic Externalism.

According to a certain kind of naïve or folk understanding of physical matter, everyday ‘solid’ objects are composed of a homogeneous, gap-less substance, with sharply defined boundaries, which wholly fills the space they occupy. A further claim is that our perceptual experience of the environment represents or indicates that the objects around us conform to this sort of conception of physical matter. Were this further claim correct, it would mean that the way that the world appears to us in (...) experience conflicts with the deliverances of our best current scientific theories in the following respect: perceptual experience would be intrinsically misleading concerning the structure of physical matter. I argue against this further claim. Experience in itself is not committed to, nor does it provide evidence for, any such conception of the nature of physical matter. The naïve/folk conception of matter in question cannot simply be ‘read-off’ from perceptual appearances. (shrink)

In the correspondence with Arnauld, Leibniz contends that each corporeal substance has a substantial form. In support he argues that to be real a corporeal substance must be one and indivisible, a true unity. I will show how this argument precludes a tempting interpretation of corporeal substances as composite unities. Rather it mandates the interpretation that each corporeal substance is a single monad.

This inaugural lecture, delivered on 17 November 2021 at the University of Neuchâtel, addresses the question: Are material objects analyzable into more basic constituents and, if so, what are they? It might appear that this question is more appropriately settled by empirical means as utilized in the natural sciences. For example, we learn from physics and chemistry that water is composed of H2O-molecules and that hydrogen and oxygen atoms themselves are composed of smaller parts, such as protons, which are in (...) turn composed of yet smaller parts, such as quarks, and so on. While the question at the center of this lecture might thus appear to fall more appropriately into the empirical domain of natural science, I argue that metaphysics in fact has an important role to play in determining how best to answer the question before us. More concretely, I propose that the Aristotelian doctrine of hylomorphism, when appropriately interpreted, provides the best metaphysical answer to the question of whether and how material objects are analyzable into more basic constituents. Hylomorphism holds that those entities to which this doctrine applies are, in some sense, compounds of matter (“hylē”) and form (“morphē” or “eidos”). Thus, the title of this lecture, “Form, Matter, Substance”, refers to the claim that lies at the center of the doctrine of hylomorphism, as applied to the domain of material objects, namely that sensible substances are the result of combining matter and form in the right sort of way; or, for short, “form + matter = substance”. I begin in Section II by providing some historical background which brings out Aristotle’s motivations for proposing the doctrine of hylomorphism in the context of his analysis of change. Section III turns to some of the main features of the contemporary hylomorphic theory I have defended especially in Koslicki (2008) and Koslicki (2018). Section IV discusses some challenging questions concerning artifacts which arise for both hylomorphic and other approaches to the metaphysics of concrete particular objects. Section V concludes by summarizing why, as contemporary metaphysicians, we should prefer a hylomorphic theory over its competitors as an analysis of concrete particular objects that is compatible with our current scientific understanding of the world.

The essay constructs an ontological theory designed to capture the categories instantiated in those portions or levels of reality which are captured in our common sense conceptual scheme. It takes as its starting point an Aristotelian ontology of “substances” and “accidents”, which are treated via the instruments of mereology and topology. The theory recognizes not only individual parts of substances and accidents, including the internal and external boundaries of these, but also universal parts, such as the “humanity” which is an (...) essential part of both Tom and Dick, and also “individual relations”, such as Tom’s promise to Dick, or their current handshake.

In this paper, we intend to offer an interpretation about the explanation of the (relative) idea of pure substance in general on John Locke’s philosophy, from Thomas Reid’s notion of ‘natural suggestion’. To achieve this aim, after contextualizing Locke’s notion of pure substance in general and distinguishing it from the idea of particular substance (section 1), we explicit that Locke’s words about the source of the idea of the former in the mind (either empirical or rational) are (...) ambiguous and inconclusive (section 2). Then, we argue that the parallels between this idea and that of ‘relation’, as well as of ‘power’ do not assist in that answer, due to some problems we identify on them (section 3). Finally, we argue that the Reidian explanation for the source of the idea of ‘mind’, from the notion of ‘natural suggestion’ allows us to i) avoid those problems and ii) inasmuch as, according to this interpretation, the idea of pure substance in general would have an empirical source, Lockian empiricism would remain intact (section 4).

Hylomorphism is the Aristotelian theory according to which substances are composed of matter and form. If a house is a substance, then its matter would be a collection of bricks and timbers and its form something like the structure of those bricks and timbers. It is widely agreed that matter bears a mereological relationship to substance; the bricks and timbers are parts of the house. But with form things are more controversial. Is the structure of the bricks and (...) timbers best conceived as a part of the house, or is it related to the house in some non-mereological fashion? Kathrin Koslicki argues that substances have formal parts, that forms are best conceived as bearing a mereological relation to substances. This paper shows that her argument fails, given the traditional and plausible distinction between substances and accidental unities. I close with a brief suggestion for a non-mereological construal of forms. (shrink)

My objective is a better comprehension of two theoretically fundamental concepts. One, the concept of a substance in an ordinary (non-Aristotelian) sense, ranging over such things as salt, carbon, copper, iron, water, and methane – kinds of stuff that now count as (chemical) elements and compounds. The other I’ll call the object-concept in the abstract sense of Russell, Wittgenstein, and Frege in their logico-semantical enquiries. The material object-concept constitutes the heart of our received logico / ontic system, still massively (...) influenced by Aristotle after almost 2.5 millennia. On such an account, the fundamentality of material objects and their attributes are the metaphysical basis of the cosmos, as reflected in our received logic, Quine’s ‘canonical notation’ – derived via the empiricism of Russell from Frege’s function-based Begriffschrifft, and consisting of concrete singular terms and variables, quantifiers and predicate-expressions. The inadequacy of Frege’s approach to understanding concepts is reflected in his initial question. Frege enquires of ‘what it is that we are calling an object’, remarking that he regards a regular definition as impossible: “we have here something too simple to admit of logical analysis”. The imagined ultimacy or simplicity of the idea of a single object (arithmetically, just a unit – one as against two, three, four, etc.) as foundational to the calculus is just that – imagined. It is also guaranteed to block the comprehension of the substance-concept. (shrink)

This paper argues that Wolff’s rejection of Leibnizian monads is rooted in a disagreement concerning the general notion of substance. Briefly, whereas Leibniz defines substance in terms of activity, Wolff retains a broadly scholastic and Cartesian conception of substance as that which per se subsists and sustains accidents. One consequence of this difference is that it leads Wolff to interpret Leibniz’s concept of a constantly striving force as denoting a feature of substance separate from its static (...) powers, and not as their replacement. For Wolff, powers are essential possibilities of acting in subjects suited for independent existence. Force is a further ingredient that provides a reason for the contingent operation of powers. Unlike Leibniz, Wolff conceives force narrowly as a principle of actuality, which he calls the nature of substance, as distinct from its principle of possibility, or essence. (shrink)

Descartes claims that God is a substance, and that mind and body are two different and separable substances. This paper provides some background that renders these claims intelligible. For Descartes, that something is real means it can exist in separation, and something is a substance if it does not depend on other substances for its existence. Further, separable objects are correlates of distinct ideas, for an idea is distinct (in an objective sense) if its object may be easily (...) and clearly separated from everything that is not its object. It follows that if our idea of God is our most distinct idea, as Descartes claims, then God must be a substance in the Cartesian sense of the term. Also, if we can have an idea of a thinking subject which does not in any sense refer to bodily things, and if bodily things are substances, then mind and body must be two different substances.

Teleological Theories of mental representation are probably the most promising naturalistic accounts of intentionality. However, it is widely known that these theories suffer from a major objection: the Indeterminacy Problem. The most common reply to this problem employs the Target of Selection Argument, which is based on Sober’s distinction between selection for and selection of . Unfortunately, some years ago the Target of Selection Argument came into serious attack in a famous paper by Goode and Griffiths. Since then, the question (...) of the validity of the Target of Selection Argument in the context of the Indeterminacy Problem has remained largely untouched. In this essay, I argue that both the Target of Selection Argument and Goode and Griffiths’ criticisms to it misuse Sober’s analysis in important respects. (shrink)

Yitzhak Melamed here offers a new and systematic interpretation of the core of Spinoza's metaphysics. In the first part of the book, he proposes a new reading of the metaphysics of substance in Spinoza: he argues that for Spinoza modes both inhere in and are predicated of God. Using extensive textual evidence, he shows that Spinoza considered modes to be God's propria. He goes on to clarify Spinoza's understanding of infinity, mereological relations, infinite modes, and the flow of finite (...) things from God's essence. In the second part of the book, Melamed relies on this interpretation of the substance-mode relation and the nature of infinite modes and puts forward two interrelated theses about the structure of the attribute of Thought and its overarching role in Spinoza's metaphysics. First, he shows that Spinoza had not one, but two independent doctrines of parallelism. Then, in his final main thesis, Melamed argues that, for Spinoza, ideas have a multifaceted structure that allows one and the same idea to represent the infinitely many modes which are parallel to it in the infinitely many attributes. Thought turns out to be coextensive with the whole of nature. Spinoza cannot embrace an idealist reduction of Extension to Thought because of his commitment to the conceptual separation of the attributes. Yet, within Spinoza's metaphysics, Thought clearly has primacy over the other attributes insofar as it is the only attribute which is as elaborate, as complex, and, in some senses, as powerful as God.

In this chapter, we provide an opinionated introduction to contemporary trope bundle theories of substance. We assess different trope bundle theories on the grounds of their two main aims: to provide an adequate account of substances or objects by means of tropes and a reductive analysis of inherence, that is, object's having tropes as their properties. Our discussion begins by a presentation of Donald C. Williams’ and Keith Campbell's paradigmatic trope theories, which maintain that tropes are independent existents. After (...) highlighting the central problems of paradigmatic trope theories, we discuss two more recent developments of trope bundle theory that also take non-relational tropes as independent existents, Anna-Sofia Maurin's and Douglas Ehring's independence theories. Finally, we present two alternative trope bundle theories, according to which tropes are dependent existents, dependence theories, namely, Arda Denkel's Saturation theory and our Strong Nuclear Theory (SNT). Although the latter two theories introduce existential dependencies among tropes, we argue that dependence theories provide a more satisfactory account of substances dividing into natural kinds than independence theories.

In his “Farewell to Substance: A Differentiated Leave-Taking”, Peter Simons reaches the provocative conclusion that the concept of substance, as it is employed by metaphysicians, has become obsolete, since in the end there may be nothing at all which answers to it. No harm is done, Simons allows, if we continue to retain an everyday notion of substance, as long as we are aware of the limitations of this practice: there is no reason in general to expect (...) that what is salient from our specifically human point of view will retain a special place in light of our most considered scientific and metaphysical theories of the world. In this paper, I argue that, contrary to Simons’ pessimistic outlook, the concept of substance continues to retain its importance for metaphysics. Among the primary explanatory roles played by the concept of substance in metaphysics is its use in designating certain kinds of entities as occupying a privileged position relative to a particular ontology. But disputes over substancehood can also target the criteria themselves relative to which an ontologically privileged position is awarded to certain taxonomic categories. In these uses, we see the concept of substance employed in an absolute, a relational and a comparative sense, to designate items as substances simpliciter, as the substances of something else, or as more or less deserving of substance status.

According to the Monist Interpretation of Descartes, there is really only one corporeal substance—the entire extended plenum. Evidence for this interpretation seems to be provided by Descartes in the Synopsis of the Meditations, where he claims that all substances are incorruptible. Finite bodies, being corruptible, would then fail to be substances. On the other hand, ‘body, taken in the general sense,’ being incorruptible, would be a corporeal substance. In this paper, I defend a Pluralist Interpretation of Descartes, according (...) to which there are many corporeal substances. In particular, I show that none of the claims in the Synopsis about incorruptibility and substance entail either that finite bodies are not substances, or that the only corporeal substance is the entire plenum.

In the correspondence with Arnauld, Leibniz contends that each corporeal substance has a substantial form.

P-zombies are creatures that are physically (functionally, behaviorally) like you and I and yet lack phenomenal consciousness. If such creatures are possible, it’s (typically) taken to show property dualism is true: phenomenal consciousness isn’t reducible to—nor does it supervene on—physical states. If inverted qualia are possible, it’s possible that you and I have identical physical states and yet you see tomatoes as green and I see tomatoes as red. If this is the case, then (again) property dualism is (typically) taken (...) to be true. In this article, I’ll show that p-zombies and inverted qualia—if they are actually possible—prove more than previously thought: if one thinks p-zombies or inverted qualia are possible, then she should endorse one of the four following theses: (i) substance dualism, (ii) we have even more reason to reject p-zombies and inverted qualia since they entail an even more radical conclusion than previously thought (i.e. substance dualism), (iii) eliminativism about selves, or (iv) friends of p-zombies and inverted qualia have homework: they need to show a relevant, plausible disanalogy between arguments for p-zombies and inverted qualia as traditionally stated and my parallel arguments that entail substance dualism. My purpose here isn’t to defend any of these particular options. Instead, my purpose is to highlight that these are the four options available to take. (shrink)

A lot of words investigated by philosophers get their inception for conventional or extra-philosophical dialect. Yet the idea of substance is basically a philosophical term of art. Its employments in normal dialect tend to derive, often in a twisted way, different from its philosophical usage. Despite this, the idea of substance differs from philosophers, reliant upon the school of thought in which it is been expressed. There is an ordinary concept in play when philosophers discuss “substance”, and (...) this is seen in the concept of object, or thing when this is contrasted with properties, attributes or events. There is also a difference in view when in the sense that while the realists would develop a materialistic theory of substance, the idealist would develop a metaphysical theory of substance. The problem surrounding substance spans through the history of philosophy. The queries have often been what is substance of? And can there be substance without its attributes? This paper tends to expose the historical problems surrounding substance. This paper criticizes the thinking which presupposes that there could be a substance without its attributes or substance existing alone. This paper adopts complimentary ontology principles which state that for anything to exist, it must serve as a missing connection to reality. This suggests that everything interconnects to each other and substance cannot exist in isolation. (shrink)

In this paper, we argue for a novel three-dimensionalist solution to the problem of persistence, i.e. cross-temporal identity. We restrict the discussion of persistence to simple substances, which do not have other substances as their parts. The account of simple substances employed in the paper is a trope-nominalist strong nuclear theory, which develops Peter Simons' trope nominalism. Regarding the distinction between three dimensionalism and four dimensionalism, we follow Michael Della Rocca's formulation, in which 3D explains persistence in virtue of same (...) entities and 4D in virtue of distinct entities. SNT is a 3D'ist position because it accounts for the persistence of simple substances in virtue of diachronically identical ‘nuclear’ tropes. The nuclear tropes of a simple substance are necessary for it and mutually rigidly dependent but distinct. SNT explains qualitative change by tropes that are contingent to a simple substance. We show that it avoids the standard problems of 3D: temporal relativization of ontic predication, Bradley's regress and coincidence, fission and fusion cases. The temporal relativization is avoided because of the analysis of temporary parts that SNT gives in terms of temporal sub-location, which is atemporal part–whole relation. (shrink)

‘Substance’ (substantia, zelfstandigheid) is a key term of Spinoza’s philosophy. Like almost all of Spinoza’s philosophical vocabulary, Spinoza did not invent this term, which has a long history that can be traced back at least to Aristotle. Yet, Spinoza radicalized the traditional notion of substance and made a very powerful use of it by demonstrating – or at least attempting to demonstrate -- that there is only one, unique substance -- God (or Nature) -- and that all (...) other things are merely modes or states of God. Some of Spinoza’s readers understood these claims as committing him to the view that only God truly exists, and while this interpretation is not groundless, we will later see that this enticing and bold reading of Spinoza as an ‘acosmist’ comes at the expense of another audacious claim Spinoza advances, i.e., that God/Nature is absolutely and actually infinite. But before we reach this last conclusion, we have a long way to go. So, let me first provide an overview of our plan. In the first section of this paper we will examine Spinoza’s definitions of ‘substance’ and ‘God’ at the opening of his magnum opus, the Ethics. Following a preliminary clarification of these two terms and their relations to the other key terms defined at the beginning of the Ethics, we will briefly address the Aristotelian and Cartesian background of Spinoza’s discussion of substance. In the second section, we will study the properties of the fundamental binary relations pertaining to Spinoza’s substance: inherence, conception, and causation. The third section will be dedicated to a clarification of Spinoza’s claim that God, the unique substance, is absolutely infinite. This essential feature of Spinoza’s substance has been largely neglected in recent Anglo-American scholarship, a neglect which has brought about an unfortunate tendency to domesticate Spinoza’s metaphysics to more contemporary views. The fourth section will study the nature of Spinoza’s monism. It will discuss and criticize the interesting yet controversial views of the eminent Spinoza scholar, Martial Gueroult, about the plurality of substances in the beginning of the Ethics; address Spinoza’s claim in Letter 50 that, strictly speaking, it is improper to describe God as “one”; and, finally, evaluate Spinoza’s kind of monism against the distinction between existence and priority monism recently introduced into the contemporary philosophical literature. The fifth and final section will explain the nature, reality, and manner of existence of modes. We therefore have an ambitious plan; let’s get down to business. (shrink)

This essay proposes a new interpretation of Clauberg’s account of the mind-body problem, against both occasionalist and interactionist readings. It examines his treatment of the mind-body relation through the lens of his theories of substance and cause. It argues that, whereas Clauberg embraces Descartes’s substance dualism, he retains a broadly scholastic theory of causation as the action of essential powers. On this account, mind and body are distinct, power-bearing substances, and each is a genuine secondary cause of its (...) own modifications. Between mental and bodily modes, however, there is only a special, divinely instituted correlation, but no causation. Clauberg’s view has the consequence that the conjunction of mind and body cannot be understood causally but only as the covariation of sensations and brain states, which he treats as mutually referring signs.

This paper argues for two claims. (1) In his biological views, Kenelm Digby tries to reconcile aspects of an Aristotelian theory of composite substance with early modern corpuscularianism. (2) From a methodological point of view, he uses the Stoic-Epicurean epistemology of common notions in order to show the adequacy of his conciliatory approach. The first claim is substantiated by an analysis of Digby’s views on the role of mixture and homogeneity in the process of animal generation. The second claim (...) is substantiated by an analysis of Digby’s views on the role of the concept of quantity in the evaluation of scientific hypotheses. Both arguments make use of the context of Digby’s philosophy: the first argument draws on his background in the work of early modern corpuscularian Aristotelians such as Daniel Sennert; the second argument draws on his background in the epistemology of Pierre Gassendi.

Millikan's account of substance concepts is based on a notion of “substance” expanded from realist notions of individuals and natural kinds. Her metaphysical notion, based on “inductive potential,” is shown to be too puristic and needs to incorporate cognizing subjects. This could preserve the realist/nondescriptionist insight that the extension of substances is determined by the world.

In this paper, I offer a systematic account of Kant’s view on ‘phenomenal substance’. Several studies have recently analyzed Kant’s notion of substance. However, I submit that more needs to be said about how this notion is reconceptualized within the critical framework to vindicate a genuine and legitimate sense of substance in the phenomenal realm. More specifically, I show that Kant’s transcendental idealism does not commit him to a rejection of substantiality in phenomena. Rather, Kant isolates a (...) general notion of substance (as ultimate subject) and argues that (i) the relationality of phenomena is compatible with this notion; and that (ii) matter and all its parts are the ultimate subjects of everything existing in space (as what is independently movable in space). I suggest that vindicating a genuine and legitimate notion of phenomenal substance has far-ranging consequences for the interpretation of Kant’s empirical realism. (shrink)

Locke’s conception of substance in general or substratum has two relatively widespread interpretations. According to one, substance in general is the bearer of properties, a pure subject, something which sustains properties but itself has no properties. I will call this interpretation traditional, because it has already been formulated by Leibniz. According to the other interpretation, substance is general is something like real essence: an underlying structure which is responsible for the fact that certain observable properties form stable, (...) recurrent clusters. I will argue that both interpretation are partly right, and what is good in them can be reconciled. The traditional interpretation captures the purpose and signficanc of the idea of substance in general, i.e. the reason why Locke says we have this idea. The real essence view is right about the real world counterpart of the idea, i.e. what sort of entity the idea corresponds to. The paper starts with a review of the strengths and weaknesses of the rival interpretations (I, II). Then I examine which part of the traditional interpretation can be sustained in light of the problems it faces (III). Thereafter I will show that the part of the traditional interpretation which can be sustained cannot stand on its own and needs to be supplemented at one point, and the real essence view can provide what is needed. This, as it were, mixed interpretation will be supported by sketching an argument which is plausible within the context of Locke’s teachings and which explains how Locke could have arrived from the view which the traditional interpretation correctly attributes to him to the view which the real essence interpretation takes him to espouse (IV). The two problematic points in this argument will be taken up in the following two sections. (V, VI). Finally, I will provide some evidence from the Drafts for Locke’s identification of substance and essence (VII). (shrink)

This essay explores the vexed issue of individual corporeal substance in Descartes' natural philosophy. Although Descartes' often referred to individual material objects as separate substances, the constraints on his definitions of matter and substance would seem to favor the opposite view; namely, that there exists only one corporeal substance, the plenum. In contrast to this standard interpretation, however, it will be demonstrated that Descartes' hypotheses make a fairly convincing case for the existence of individual material substances; and (...) the key to this new found individuation is a long neglected set of passages in the Principles of Philosophy.

The use of counterfactuals for considerations of algorithmic fairness and explainability is gaining prominence within the machine learning community and industry. This paper argues for more caution with the use of counterfactuals when the facts to be considered are social categories such as race or gender. We review a broad body of papers from philosophy and social sciences on social ontology and the semantics of counterfactuals, and we conclude that the counterfactual approach in machine learning fairness and social explainability can (...) require an incoherent theory of what social categories are. Our findings suggest that most often the social categories may not admit counterfactual manipulation, and hence may not appropriately satisfy the demands for evaluating the truth or falsity of counterfactuals. This is important because the wide- spread use of counterfactuals in machine learning can lead to misleading results when applied in high-stakes domains. Accordingly, we argue that even though counterfactuals play an essential part in some causal inferences, their use for questions of algorithmic fairness and social explanations can create more problems than they resolve. Our positive result is a set of tenets about using counterfactuals for fairness and explanations in machine learning. (shrink)

The purpose of this article is to reconstruct Aristotle’s distinction between primary substances and their homonyms. It is shown that the Stagirite regards both body parts and artefacts as mere homonyms of primary substances when they are no longer capable of performing their function (ergon) and actualizing their end (telos). In the course of the present discussion, Aristotle’s approach is confronted with his famous doctrine of the four causes, whilst an analysis of the examples given by the Stagirite serves the (...) purpose of determining the ontic status of homonyms. Subsequently, this paper argues that Aristotle’s hylomorphism not only defies the functionalist assumption of the irrelevance of matter but also precludes the possibility of equating artefacts with living organisms. The discussion concludes with an observation that primary substances which are truly (alēthōs) and things which are only homonymously (plēn homōnymōs) require different definitions. (shrink)

In book Zeta of the Metaphysics and elsewhere Aristotle appears to commit himself to the following propositions: (1) No universal can be substance; (2) Form is a universal; and (3) Form is that which is most truly substance. These propositions appear to constitute an inconsistent triad lying at the heart of Aristotle’s ontology. A number of attempts have been made to rescue Aristotle from the charge of inconsistency. Some have claimed that Aristotle did not subscribe to (1), but (...) only to the proposition that nothing predicated universally can be substance. Others hold that, contrary to (2), form is not a universal but peculiar to each individual. Still others argue that the sense of ‘substance’ in which the species form is a substance is not the sense in which no universal is substance. I argue that none of these attempts to rescue Aristotle from the charge of inconsistency is ultimately defensible. (shrink)

In Morris I presented in outline a new interpretation of the famous ‘substance argument’ in Wittgenstein’s Tractatus. The account I presented there gave a distinctive view of Wittgenstein’s main concerns in the argument, but did not explain in detail how the argument works: how its steps are to be found in the text, and how it concludes. I remain convinced that the interpretation I proposed correctly identifies the main concerns which lie behind the argument. I return to the argument (...) here in order to elaborate in fuller detail the relation between those concerns and the actual course of the text. (shrink)

According to the theory of intrinsic value and moral standing known as the “substance view,” all human beings have intrinsic value, full moral standing and, with these, a right to life. The substance view has been defended by numerous contemporary philosophers who use the theory to argue that the standard human fetus has a right to life and, ultimately, that abortion is prima facie seriously wrong. In this paper, I identify three important errors committed by some of these (...) philosophers in their defense of the theory---what I refer to as the “extratheoretical-proposition error,” “quantitative-differences error,” and “non-normative-answer error”---and conclude that these errors render their defense inadequate.

The paper offers a new account of Spinoza's conception of “substance”, the fundamental building block of reality. It shows that it can be demonstrated apriori within Spinoza's metaphysical framework that (i) contrary to Idealist readings, for Spinoza there can be no substance that is not determined or modified by some other entity produced by substance; and that (ii) there can be no substance (and hence no being) that is not a thinking substance.

Must we choose between reducing material substances to collections of properties, a’ la Berkeley and Hume or positing bare particulars, in the manner of Locke? Having repudiated the notion that a substance could simply be a collection of properties existing on their own, is there a viable alternative to the Lockean notion of a substratum, a being essentially devoid of character? E.J. Lowe and Michael Loux would answer here in the affirmative. Both recommend hylomorphism as an upgrade on the (...) metaphysics of the British empiricists: treating a material substance as its essential 'form,' this embodied 'substance' universal being, in turn, the substratum in which its 'accidents' inhere. Here, I evaluate this Aristotelian metaphysics, identifying the advantages it enjoys over the empiricist's alternatives pertaining to dependence, unity, identity, change, and the distinction between essential and accidental properties. I also develop solutions to the two problems that Loux sees it posing. (shrink)

‘Substance’ (substantia, zelfstandigheid) is a key term of Spinoza’s philosophy. Like almost all of Spinoza’s philosophical vocabulary, Spinoza did not invent this term, which has a long history that can be traced back at least to Aristotle. Yet, Spinoza radicalized the traditional notion of substance and made a very powerful use of it by demonstrating – or at least attempting to demonstrate -- that there is only one, unique substance -- God (or Nature) -- and that all (...) other things are merely modes or states of God. Some of Spinoza’s readers understood these claims as committing him to the view that only God truly exists, and while this interpretation is not groundless, we will later see that this enticing and bold reading of Spinoza as an ‘acosmist’ comes at the expense of another audacious claim Spinoza advances, i.e., that God/Nature is absolutely and actually infinite. But before we reach this last conclusion, we have a long way to go. So, let me first provide an overview of our plan. In the first section of this paper we will examine Spinoza’s definitions of ‘substance’ and ‘God’ at the opening of his magnum opus, the Ethics. Following a preliminary clarification of these two terms and their relations to the other key terms defined at the beginning of the Ethics, we will briefly address the Aristotelian and Cartesian background of Spinoza’s discussion of substance. In the second section, we will study the properties of the fundamental binary relations pertaining to Spinoza’s substance: inherence, conception, and causation. The third section will be dedicated to a clarification of Spinoza’s claim that God, the unique substance, is absolutely infinite. This essential feature of Spinoza’s substance has been largely neglected in recent Anglo-American scholarship, a neglect which has brought about an unfortunate tendency to domesticate Spinoza’s metaphysics to more contemporary views. The fourth section will study the nature of Spinoza’s monism. It will discuss and criticize the interesting yet controversial views of the eminent Spinoza scholar, Martial Gueroult, about the plurality of substances in the beginning of the Ethics; address Spinoza’s claim in Letter 50 that, strictly speaking, it is improper to describe God as “one”; and, finally, evaluate Spinoza’s kind of monism against the distinction between existence and priority monism recently introduced into the contemporary philosophical literature. The fifth and final section will explain the nature, reality, and manner of existence of modes. We therefore have an ambitious plan; let’s get down to business. (shrink)

In this paper, I inspect the grounds for the mature Spinozist argument for substance monism. The argument is succinctly stated at Ethics Part 1, Proposition 14. The argument appeals to two explicit premises: (1) that there must be a substance with all attributes; (2) that substances cannot share their attributes. In conjunction with a third implicit premise, that a substance cannot not have any attribute whatsoever, Spinoza infers that there can be no more than one substance. (...) I begin the inspection with the analysis of the first premise, which is provided in the form of the four proofs of God’s existence in Ethics Part 1, Proposition 11. While demonstrating how Spinoza adopts a progressive approach, where the fourth proof of God’s existence is more successful and persuasive than the third, which is more successful than the second, etc., I also unpack concepts central to Spinoza’s thinking here, including the concepts of reason (ratio) and power (potesta or potentia). I then analyze the second premise of the Spinozist argument for substance monism, as established by Ethics Part 1, Proposition 4 in conjunction with Ethics Part 1, Proposition 5. I take up and respond to the objection attributed to Leibniz that a substance p can have the attributes x and y and a substance q can have the attributes y and z, and thus that substances can share some attributes while remaining distinct. Throughout the study, my attention is focused on the argumentative procedures Spinoza adopts. This yields a close, internalist reading of the text where Spinoza effectively embraces substance monism. In conclusion to this study, I underscore to the originality of Spinoza’s argument for seventeenth century theories of substance. (shrink)

In the Discourse on Metaphysics Leibniz put forward his famous complete-concept definition of substance. Sometimes this definition is glossed as stating that a substance is an entity with a concept so complete that it contains all its predicates, and it is thought that it follows directly from Leibniz’s theory of truth. Now, an adequate definition of substance should not apply to accidents. But, as I shall point out, if Leibniz’s theory of truth is correct then an accident (...) is an entity with a concept so complete that it contains all its predicates. The aim of this paper is to clarify Leibniz’s notion of substance in the Discourse with a view to explaining how that definition successfully distinguishes between substances and accidents. (shrink)

I claim that caricature is an epistemically defective depiction. More precisely, when employed in service to some epistemic uptake, I claim that caricature can have a non-negligible epistemic effect only for a less than ideally rational audience with certain cognitive biases. An ideally rational audience, however, would take all caricature to be what I refer to as fairground caricature, i.e., an interesting or entertaining form of depiction that is at best only trivially revelatory. I then argue that any medium (or (...) genre) substantially employing caricature (or standardly featuring or prescribing its employment) in service to some epistemic uptake is to that extent an epistemically defective medium (e.g., beliefs informed by works specific to that medium are to that extent unwarranted). I then show the editorial cartoon to be just such an epistemically defective medium. (shrink)

William Smith’s recent article criticises the so-called orthodox approaches to the normative analysis of healthcare resource allocation, associated to the requirement that decision-makers should abide by strictly procedural principles of legitimacy defining a deliberative democratic process. Much of the appeal of Smith’s argument goes down to his awareness of real-world processes and, in particular, to the large gap he identifies between well-led democratic deliberation and the messiness of the process through which the intuitively legitimate Affordable Care Act (ACA) was created. (...) This reply aims to demonstrate that the ACA provides no counterexample to orthodox views, seizing this opportunity to explore the specific space that the procedural principles populating orthodox accounts are meant to regulate. Neither general questions of healthcare justice concerning, for example, universal access nor, relatedly, the activity of elected politicians falls within the natural scope of application of such principles, revealing a much more complex picture of the interactions between justice and legitimacy as well as substantive and procedural considerations than acknowledged by Smith. In the end, orthodox accounts of healthcare resource allocation turn out to provide a precious fund of theoretical resources for the normative study of administrators, which might be useful well beyond bioethics and health policy.

Many contemporary philosophers of mind disagree with substance dualism, saying that despite the failure of physical theories of mind, substance dualism cannot be advocated, because it faces more serious problems than physical theories, lacking compatibility with philosophical arguments and scientific evidence. Regardless of the validity of the arguments in support of substance dualism, it is demonstrated in this article that this theory is coherent, with no philosophical or scientific problems. The main arguments of opponents of substance (...) dualism are explained and criticized in this respect. Based on this, it becomes clear that the interaction of soul and body has a reasonable philosophical explanation, the problem of the pairing of soul and body, although it may not have a scientific explanation, it has a philosophical and theological solution, the principle of the physical causal closure lacks conclusive reasons and cannot reject the existence of the soul, the existence of the soul does not contradict the theory of evolution, the dependence of the soul on the brain is compatible with its independence, and finally, the principle of simplicity does not make any problem for accepting the substance dualism.
