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)

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)

I critically examine the view that Descartes’s independence conception (IC) of substance plays a crucial role in his “separability argument” for substance dualism. I argue that IC is a poisoned chalice. I do so by considering how an IC-based separability argument fares on two different ways of thinking about principal attributes. On the one hand, if we take principal attributes to be universals, then a separability argument that deploys IC establishes a version of dualism that (...) is unacceptably strong. On the other hand, if we take principal attributes to be tropes, then IC introduces challenges which undermine the argument. This is partly because the assumption of tropes makes it possible to distinguish several versions of substance dualism, versions which differ with respect to their degree of generality. I argue that taking principal attributes to be tropes makes it challenging to establish any of these versions by way of an IC-based separability argument. I conclude the paper by suggesting a way forward for the proponent of the separability argument. (shrink)

I advance a type of conceptualist argument for substance dualism – minimally, the view that we are spiritual substances that have bodies – based on the understandability of what it would be for something to be a spirit, e.g. what it would be for God to be a spirit. After presenting the argument formally, I clarify and defend its various premises with a special focus on what I take to be the most controversial one, namely, if thinking (...) matter is metaphysically possible, it is not the case that we have a distinct positive concept of God's being a divine spirit.

In a sequel to the author's argument for dualism from the lived experience of time, this paper continues the line of thought initiated by in that study a bit further by considering the implications of our experience of being in space for dualism. I conclude that four-dimensionalism cannot accommodate the facts of our experience of ourselves as being in time - localized in space but not located there after the manner of a material thing. Substance dualism, however, makes (...) perfect sense of all these facts, which helps confirm the natural presumption in favor of that view. REVISED: March 24, 2022 with substantive changes. (shrink)

This is a companion to an earlier essay, "An Argument for Dualism from the Lived Experience of Time," in which I argue that our lived experience of being in space is best accounted for on a substance dualist ontology of the experiencing subject and a 3-dimensionalist account of time. Such an account excludes the metaphysical possibility of 4-dimensionalism as a literal, descriptive account of noumenal time inasmuch as it is incompatible with facts we know with greater certainty than (...) any scientific theory.

Scholars have rejected Wilfrid Sellars’ argument for an ontology of absolute processes on the grounds that it relies on a dubious and dogmatic appeal to the homogeneity of color. Borrowing from Rosenthal’s recent defense, but ultimate rejection of homogeneity, I defend this claim of on Sellarsian/Kantian transcendental grounds, and reconstruct the remainder of his argument. I argue that Sellars has good reason to suppose that homogeneity is a necessary condition of any possible experience, including indirect experience of theoretical-explanatory (...) posits, and therefore good reason to hold that Reductive Materialism, as he conceives it, is an untenable account of color. The remainder of his argument aims to answer the question of what the metaphysical relation is between the state of an experiencing subject that we take color to be and the colorless microphysical particles that we take to constitute that subject. After rejecting Substance Dualism, Epiphenomenalism, and Wholistic or Emergent Materialism as explanatorily inadequate, Sellars proposes that both color-states and micro-physical particles should be understood as manifestations of an underlying ontology on absolute processes.

The third Meditation is typically understood to contain two a posteriori arguments for the existence of God. The author focuses on the second argument, where Descartes proves the existence of God partly in virtue of proving that Descartes cannot be the cause of himself. To establish this, Descartes argues that if he were the cause of himself, then he would endow himself with any conceivable perfection. The justification for this claim is that bringing about a substance is more (...) difficult than creating an attribute, so anything that can do the former can do the latter. While current explanations of this justification are either implausible or inadequate, the author argues that this principle derives support from a scholastic distinction between being-as-such and determinate being. With this distinction in view, we can make sense of Descartes's argument without appealing to ambiguous or inadequate notions. (shrink)

I seek to explicate the ways in which the soul is deemed immaterial in two main strands of Islamic philosophy, and then consider some arguments for the immateriality of the soul. To do so, I first overview Avicenna’s theory of the spiritual incipience (al-ḥudūth al-rūḥānī) of the soul and his version of substance dualism. I will then discuss Mullā Ṣadrā’s view of the physical incipience (al-ḥudūth al-jismānī) of the soul and how the soul emerges and develops towards immateriality on (...) his account. I then overview and discuss five of the most important arguments presented by these two great Muslim philosophers in favor of the immateriality of the soul. To do so, I will also point out some of the main contemporary physicalistic views of the nature of mind and mental states. I will then argue that arguments for the immateriality of the soul – dealt with here – do not indeed target or challenge any significant versions of contemporary physicalism. Moreover, these arguments involve conflations of epistemological or ontological issues. (shrink)

What is the role of the principle of sufficient reason in Baruch Spinoza’s ontological proof for God’s existence? Is this role identical within Spinoza’s early work on method, the Treatise on the Emendation of the Intellect, and his magnum opus, the Ethics? This paper argues affirmatively that the methodology employed within the Ethics is consonant with that method found within the Treatise, and this claim is substantiated through an engagement with the influential works of Don Garrett and Aaron Garrett. It (...) is also demonstrated through an original reconstruction of the Treatise itself. In this reconstruction, basic premises are identified which can validly prove Spinoza’s intended conclusion of substance monism. It is finally determined that what the Treatise and the Ethics share, specifically, is a methodology which begins with non-nominal definitions that denote the real, sufficient causes of their respective objects. However, at certain junctures, this methodology is expressed with greater consistency within the Treatise as opposed to within the Ethics. Evidence for this will be provided from the primary texts themselves and from the subsequent analyses of Don Garrett and Aaron Garret as well. (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)

Descartes maintained substance dualism, the thesis that no substance has both mental and material properties. His main argument for this thesis, the so-called separability argument from the Sixth Meditation (AT VII: 78) has long puzzled readers. In this paper I argue that Descartes’ independence conception of substance (which Descartes presents in article 51 of the Principles) is crucial for the success of the separability argument and that Descartes used this conception of substance to (...) defend his argument for substance dualism from an important objection.

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)

In the first part of this series it was argued that there is an inextricable bond between economic and cultural liberalism such that when Catholics identify the faith with the defence of neoliberal economics, even though they may oppose abortion, they end up promoting exactly that which they oppose. In this the second part this point is expanded upon and the argument made more explicit and that by reference to Pope Francis’ recent Apostolic Exhortation, Gaudium Evangelii. The Exhortation evidences (...) a view of matters economic that sits ill with capitalism, a point understood by Catholic commentators who champion Neoliberalism. This essay argues that Francis’ comments are nothing new, especially when compared to what John Paul II and Benedict XVI have written on the subject; indeed, that Francis’ Exhortation can be seen as a tempering of their critique of economic liberalism. The essay attempts to tease out what it is that informs the critique of the popes and shows that it has to do with what flows out from the rejection of metaphysics proper, a rejection that defines Modernity, and which ends in the deracination of all things such that even the very concept of ‘substance’ is dissolved and, thereby, all is made plastic and malleable, including human life. The important point the essay wishes to make is this: the popes are quite clear that the form a culture’s economy takes can both ground and exacerbate this anti-essentialist logic, what’s more the economy above all others that does this is the one they identify with neoliberal capitalism. As a consequence, Catholics who champion this form of economic theory must think seriously as to whether or not they or the popes are wrong on this matter. (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.

ABSTRACTMost of Spinoza’s arguments for God’s existence do not rely on any special feature of God, but instead on merely general features of substance. This raises the following worry: those arguments prove the existence of non-divine substances just as much as they prove God’s existence, and yet there is not enough room in Spinoza’s system for all these substances. I argue that Spinoza attempts to solve this problem by using a principle of plenitude to rule out the existence of (...) other substances and that the principle cannot be derived from the PSR, as many claim.Abbreviation: PSR: Principle of Sufficient Reason.

Philosophy is experiencing a resurgence of property (PD) and generic substance dualism (SD). One important argument for SD that has played a role in this resurgence is some version of a modal argument. Until recently, premise (3) of the argument (Possibly, I exist, and no wholly physical objects exist.) has garnered most of the attention by critics. However, more recently, the focus has also been on (2) (Wholly physical objects are essentially, wholly, and intrinsically physical and (...) wholly spiritual substances are essentially, wholly, and intrinsically immaterial.). Andrew Bailey has provided one of the best criticisms of (2) on offer. In what follows, I present and clarify one form of the argument and defend premise (2) by responding to important defeaters proffered by Andrew Bailey and his contingent physicalism. (shrink)

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)

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)

In Metaphysics Z.6, Aristotle argues that each substance is the same as its essence. In this paper, I defend an identity reading of that claim. First, I provide a general argument for the identity reading, based on Aristotle’s account of sameness in number and identity. Second, I respond to the recent charge that the identity reading is incoherent, by arguing that the claim in Z.6 is restricted to primary substances and hence to forms.

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.

A main element in Richard Swinburne’s (2019) argument for substance dualism concerns the conditions of a person’s continued existence over time. In this commentary I aim to question two things: first, whether the kind of imaginary cases that Swinburne relies on to make his case should be accorded the kind of weight he supposes; and second, whether philosophers should be concerned to give any substantial theory, of the sort that dualism and its competitors are apparently meant to provide, (...) to explain the conditions of personal identity after all. My suggestion, instead, will be that the concept of a person’s continued existence is better taken as philosophically unanalyzable. (shrink)

In this article I examine the compatibility of a leading trope bundle theory of substance, so-called Nuclear Theory, with trope theory more generally. Peter Simons (1994) originally proposed Nuclear Theory (NT), and continues to develop (1998, 2000) and maintain (2002/03) the view. Recently, building on Simons’s theory, Markku Keinänen (2011) has proposed what he calls the Strong Nuclear Theory (SNT). Although the latter is supposed to shore up some of NT’s weaknesses, it continues to maintain NT’s central tenet, the (...) premise that tropes are variously existentially interdependent. I argue that the central tenet of NT frustrates several important aims of trope theory. If my arguments go through, they also implicate SNT. Because of this, I largely set aside other aspects of NT and SNT and focus on their shared central tenet. (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)

According to the Christian doctrine of bodily resurrection, human persons will have an embodied existence in eternity. Many Christian materialists, especially Lynne Rudder Baker, Trenton Merricks, and Kevin Corcoran, argue that the doctrine of bodily resurrection creates serious problems for substance dualism (dualism). These critiques argued that bodily resurrection is made trivial by dualism, that dualism makes it difficult if not impossible to explain why we need to be embodied, or that dualism should be rejected as bodily resurrection is (...) better accounted for by a materialist view. As of yet, there has been no systematic analysis of these arguments in the literature. This paper fills that gap and argues that each of these objections to dualism fail. In making these arguments I make use of neo-Aristotelian metaphysics to provide a theory of embodiment for substance dualism. Accordingly, the body is a complex structural mode of the soul. The essence of the soul is the internal efficient cause and teleological guide of the functions and structure of the body. As such, the body is an ensouled physical structure, not a mere physical machine, but has both physical and non-physical aspects. (shrink)

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

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.

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.

Descartes's "conceivability argument" for substance-dualism is defended against Arnauld's criticism that, for all he knows, Descartes can conceive himself without a body only because he underestimates his true essence; one could suggest with equal plausibility that it is only for ignorance of his essential hairiness that Descartes can conceive himself as bald. Conceivability intuitions are defeasible but special reasons are required; a model for such defeat is offered, and various potential defeaters of Descartes's intuition are considered and rejected. (...) At best though Descartes shows the separability of mind from body, not (as he claims) their actual separateness. (shrink)

In Form, Matter, Substance, Kathrin Koslicki articulates and defends her preferred brand of hylomorphism, weighing in on how we should conceive of the matter and the form of such compounds, and on how they can qualify as fundamental “substances” despite being ontologically dependent on their components. I review Koslicki’s principal claims and conclusions (§1), and then raise some concerns about her master argument for “individual forms” (§2) and her criticism of standard essentialist accounts of artifacts (§3).

Substance dualism has received much attention from philosophers and theologians in contemporary literature. Whilst it may have been fashionable in the recent past to dismiss substance dualism as an unviable and academically absurd position to hold, this is no longer the case. My contention is not so much the merits of substance dualism in general, but a more specified variation of substance dualism. My specific contribution to the literature in this article is that I argue for (...) the viability of pure substance dualism as a more satisfactory option in contrast to compound or composite varieties of substance dualism. I put forth one argument and tease out the implications that make compound dualism less than satisfactory. I conclude that, minimally, more work is required on compound variations of dualism to make it a more appealing and a philosophically satisfactory option. (shrink)

In the whole Corpus Platonicum, we find in principle only one "direct argument" (Charles Kahn) for the existence of the ideas (Tim.51d3-51e6). The purpose of the article is to analyse this argument and to answer the question of why Plato in the Timaeus again defended the existence of the ideas despite the objections in the Parmenides. He defended it again because the latent presupposition of the apories in the Parmenides, the substantial view of sensibles, is removed through the (...) introduction of space as "substantialized extension". First (I) it is shown that Plato remained in dialogues, like the Sophist and Politicus, faithful to the "theory of ideas" despite his criticism in the Parmenides. The common theme in the trilogy of the Theaetetus, Sophist and Politicus is to refute relativism by showing that any relativism presupposes something absolute that is something like the "theory of ideas". The second part of the paper (II) examines closely the logical structure of the argument for the existence of ideas in the Timaeus (51d3-52a7). The third part (III) shows how this argument can avoid the criticism of ideas in the Parmenides. In the Parmenides, sensibles are treated as substantial entities. But, as the Timaeus shows, sensibles are not substantial entities but merely qualities, namely qualities of space, which is the only substance in the sensible world. A shortened English version of the paper appeared in Proceedings of the Fourth Symposium Platonicum, Granada, Selected papers, ed. by T. Calvo/L. Brisson, Academia Verlag, St. Augustin, 1997, 179-186. -/- But the only "direct argument" (Tim.51d3-51e6) seems to be interestingly flawed. Cf. Ferber, Rafael; Hiltbrunner, Thomas, (2005). (shrink)

Leibniz argues that there must be a fundamental level of simple substances because composites borrow their reality from their constituents and not all reality can be borrowed. I contend that the underlying logic of this ‘borrowed reality argument’ has been misunderstood, particularly the rationale for the key premise that not all reality can be borrowed. Contrary to what has been suggested, the rationale turns neither on the alleged viciousness of an unending regress of reality borrowers nor on the Principle (...) of Sufficient Reason, but on the idea that composites are phenomena and thus can be real only insofar as they have a foundation in substances, from which they directly ‘borrow’ their reality. The claim that composites are phenomena rests in turn on Leibniz's conceptualism about relations. So understood, what initially looked like a disappointingly simple argument for simples turns out to be a rather rich and sophisticated one. (shrink)

Though Spinoza's definition of God at the beginning of the Ethics unequivocally asserts that God has infinitely many attributes, the reader of the Ethics will find only two of these attributes discussed in any detail in Parts Two through Five of the book. Addressing this intriguing gap between the infinity of attributes asserted in E1d6 and the discussion merely of the two attributes of Extension and Thought in the rest of the book, Jonathan Bennett writes: Spinoza seems to imply that (...) there are other [attributes] – he says indeed that God or Nature has “infinite attributes.” Surprising as it may seem, there are reasons to think that by this Spinoza did not mean anything entailing that there are more than two attributes. In this paper I will argue that Bennett’s claim is fundamentally wrong and deeply misleading. I do think, however, that addressing Bennett’s challenge will help us better understand Spinoza’s notion of infinity. I will begin by summarizing Bennett’s arguments. I will then turn to examine briefly the textual evidence for and against his reading. Then I will respond to each of Bennett’s arguments, and conclude by pointing out theoretical considerations which, I believe, simply refute his reading. (shrink)

I examine Du Châtelet’s methodology for physics and metaphysics through the lens of her engagement with Newton’s Rules for Reasoning in Natural Philosophy. I first show that her early manuscript writings discuss and endorse these Rules. Then, I argue that her famous published account of hypotheses continues to invoke close analogues of Rules 3 and 4, despite various developments in her position. Once relevant experimental evidence and some basic constraints are met, it is legitimate to inductively generalize from observations; general (...) hypotheses can thereafter be assumed as true until contrary experiments show otherwise. I conclude by arguing that this account of induction plays an essential role in her metaphysics, both in an argument for simple substances—which has an inductive premise—and in her attempt to distinguish acceptable and unacceptable metaphysical commitments.

The purpose of this paper is to debate a version of the Cartesian argument from doubt for mind–body dualism which has been proposed recently by Ari Maunu in this journal (Inquiry, 61/4). After introducing Maunu's argument, one section is devoted to the critique of his argument. In this section, in addition to some other criticisms, we will consider a methodological parallel to Maunu's argument that is like his style of argumentation but is intended to draw the (...) opposite conclusion. The discussion section includes Richard Swinburne's critical commentary on these two contrasting arguments. It also examines Swinburne's amended version of a Cartesian argument, which he believes to offer support for Maunu's position. (shrink)

This is a response to Stephen Maitzen’s paper. ‘Moral Conclusions from Nonmoral Premises’. Maitzen thinks that No-Ought-From-Is is false. He does not dispute the formal proofs of Schurz and myself, but he thinks they are beside the point. For what the proponents of No-Ought-From-Is need to show is not that you cannot get SUBSTANTIVELY moral conclusions from FORMALLY non-moral premises but that you cannot get SUBSTANTIVELY moral conclusions from SUBSTANTIVELY non-moral premises. And he believes that he can derive substantively moral (...) conclusions from FORMALLY moral but SUBSTANTIVELY nonmoral premises. However his argument relies on what I call ‘taxonomic essentialism’, the thesis that sentences do not change their semantic characters from context to context or from world to world. In particular, they do not change their META-ETHICAL status from context to context or world to world. If a sentence is non-moral at one world it is non-moral at all the rest. This thesis leads to contradictions (with some propositions as both moral and non-moral) and even if (as is perhaps possible) these contradictions can be avoided, it leads to further consequences that are palpably absurd. Thus It may be possible to derive substantively moral conclusions from premises that are not substantively moral, but if it is, Maitzen has failed to prove the point. (shrink)

John Locke is often understood as the inaugurator of the modern discussion of personal human identity—a discussion that inevitably falls back on his own theory with its critical reliance on memory. David Hume and Sigmund Freud would later make arguments for what constituted personal identity, both relying, like Locke, on memory, but parting from Locke's company in respect the role that memory played. The purpose of this paper will be to sketch the groundwork for Locke's own theory of personal identity (...) and consider some common objections tied to his special reliance on memory. Then, we will investigate the extent to which Hume and Freud refined their respective concepts of self-identity in ways that escape some of the most intractable objections to Locke's theory in its dependence on memory. Finally, we will consider which theorist's conception of self-identity best accords with our notion of the cyber-self, or psychological subjectivity in the context of cyberspace. For Locke, the nature of self-identity is that it is continuous across time, and to remain uninterrupted it must be beholden to a psychological process, rather than a material or immaterial substance.

This paper is based on the comments I gave to Alfred Mele regarding his original Zygote Argument during my presentation at a small workshop on manipulation arguments in Budapest back in 2012. After those comments, Mele changed the conclusion of his original Zygote Argument (OZA) from a positive, explanatory conclusion to a negative, non-explanatory conclusion--and, correspondingly, redefined 'incompatibilism' so that it would no longer refer in his work to the view that determinism precludes (undermines, eliminates, destroys, etc.) free (...) will, but refers narrowly to the perhaps spurious association claim that appears in the conclusion of the revised Zygote Argument (Mele 2013+). Yet, over the last decade, Mele has made no comment in print about the changes he made, the invalidity objection that led to them, nor to the fact that his revised Zygote Argument was originally presented by me as a (non-optimal) reaction to my invalidity objection to his original Zygote Argument. To my knowledge, Mele has only mentioned this 2015 paper once, at it was not in the context of understanding manipulation arguments; it was, rather, in the context of defending his revised, non-explanatory definition of 'incompatibilism' at the opening of Aspects of Agency (p. 6, n. 4). There, Mele singles out *just this 2015 paper* as a place where they'll find what Mele degrades as a type of nonstandard/nontraditional definition of 'incompatibilism' that he rejects. This is notable because Mele provides no empirical evidence that his preferred definition is standard, and most (including Lehrer, who coined the term) reject the negative, non-explanatory, association-based definition that Mele came to endorse in the aftermath of my invalidity objection to OZA. So, if Mele had a genuine concern about philosophers who use the term 'incompatibilism', then Mele could have--and should have--named almost any leading figure in free will for this purpose (since most--including Pereboom, Vihvelin, Haji, etc.) reject the non-explanatory definition that Mele-2013+ now endorses. Yet, for untold reasons, Mele isolated the working definition of 'incompatibilism' used in one paper by one unemployed junior researcher to use as his example--even though Neil Levy had used this same definition in previously published work (eg. Levy 2011). Moreover, if Mele were genuinely interested in helping his readers understand the ambiguity of terms like 'compatibilism' and 'incompatibilism' it is a mystery that he referenced a paper in which nothing of substance hung on the definitions given to these terms -- especially considering that he might have instead pointed them to my OTHER 2015 paper, "A Critique of Vihvelin's Three-Fold Classification" in which the MAIN AIM of the paper is to expose the difficulties facing anyone who wants to define the terms 'compatibilism' and 'incompatibilism' in a way that everyone will accept (including a critique of the negative, non-explanatory "incompossibilist" definition that Mele adopted after my objection to OZA). By all appearances, Mele's main aim in citing specifically THIS paper and none of my other work was to give readers the false impression that my working definition of 'incompatibilism' played some role in my charge that his argument is invalid (which it doesn't, given that the term doesn't appear in either the premises or conclusion of that argument). Mele adds to this unseemly rhetorical campaign in his book *Manipulation Agents* where he mentions an invalidity objection in the intro (p. 84) and then discusses that objection in the final lines of Chapter 5 of the book (p. 120-121). The invalidity objection discussed here is completely pedantic, has never been seriously raised in the primary literature (and was previously addressed in multiple places my multiple philosophers, including me), and has nothing whatever to do with my invalidity objection. In other words, Mele was content to discuss an invalidity objection that no one has ever had to an argument that is clearly valid while completely ignoring the ONLY substantive invalidity objection to his argument in print. This is unfortunate, because it has led to serious confusion --including the patently false description of my invalidity objection to OZA as an objection to the revised version of the Zygote Argument that Mele adopted in *response* my objection (e.g., Capes mistakenly claims "Mickelson (2015) contends that arguments like this [i.e. like the revised Zygote Argument] are invalid. But that’s because she defines “incompatibilism” differently than I’ve defined it here" in his "Manipulation Arguments and Direct Arguments" chapter in the 2023 Wiley-Blackwell Companion to Free Will; I did not say this, and the definition of 'incompatibilism' is irrelevant to my objection). In "The Zygote Argument Is Invalid--Now What?", I simply use the invalidity of the simple 2-premise Zygote Argument as a foil to make a series of more philosophically significant points (e.g. regarding the dialectical structure of the free-will debate, the role of best-explanation reasoning, and to develop the first-ever "master manipulation argument"). Mele has yet to address my reasons for calling attention to the non-trivial invalidity of his OZA or to any of my answers to the "Now What?" question in this paper, even though this question and my proposed answers to this question are the paper's main point. For those interested in a more recent discussion of how the logical and metaphilosophical observations made in this "Now What?" paper have helped to move the free-will debate forward, I suggest looking at the discussions of the "paradigm shift" in the free-will debate that helps to explain why the free-will debate has become mired in stalemates and empty verbal disputes that are found, for example, in my contributions to the Wiley-Blackwell Companion to Free Will (Intro and Chapter 4, 2023) and my paper "Free Will, Self-Creation, and the Paradox of Moral Luck" (2019).

The tenth proposition of Spinoza’s Ethics reads: ‘Each attribute of substance must be conceived through itself.’ Developing and defending the argument for this single proposition, it turns out, is vital to Spinoza’s philosophical project. Indeed, it’s virtually impossible to overstate its importance. Spinoza and his interpreters have used EIp10 to prove central claims in his metaphysics and philosophy of mind (i.e., substance monism, mind-body parallelism, mind-body identity, and finite subject individuation). It’s crucial for making sense of his (...) epistemology (i.e., Spinoza’s account of knowledge and response to skepticism) and in resolving puzzles within the Ethics (i.e., explaining human ignorance of all but two attributes). Even those who do not attribute some of the above claims to Spinoza need EIp10 to defend much of what they believe about Spinoza’s system. This paper locates a previously unnoticed argument for this proposition in Spinoza’s Short Treatise on God, Man, and His Well Being. There, Spinoza shows himself concerned with a powerful and underappreciated form of philosophical skepticism, one with surprising echoes in the work of his contemporary Leibniz as well as in the later Wittgenstein. Spinoza’s introduction of E1p10 in the Ethics circumvents this form of skepticism, solving the problem the Short Treatise envisions while also explaining that text’s argument’s absence from the explicit justificatory structure of the Ethics.

In Ethics 1p5, Spinoza asserts that “In Nature there cannot be two or more substances of the same nature or attribute”. This claim serves as a crucial premise in Spinoza’s argument for substance monism, yet Spinoza’s demonstration of the 1p5 claim is surprisingly brief and appears to have obvious difficulties. This paper answers the principle difficulties that have been raised in response to Spinoza’s argument for 1p5. The key to understanding the 1p5 argument lies in a (...) proper understanding of the substance-attribute relationship and the principles of metaphysical individuation that Spinoza accepts. (shrink)

Argumentative thinking has two aspects, viz. positive and negative. Such thinking effectively ignores the content since the actual object is considered “out there” beyond the subjective thinking that is going on “in here” or inside oneself or the finite mind. No explicit connection is established between the subjective and objective worlds or realms. This type of thinking is of necessity concerned only with its own knowing or with itself, thus Hegel calls this vanity. In this sense it is indifferent to (...) what is outside it, thus it is abstract thought – thought that is stripped from its actual content. This difference or indifference is the negative aspect of argumentative thinking. In addition, we may understand it positively as a union/unity with an “I think” or thinking ego conjoined immediately to an objective content. The objective content is supposed to be the truth that the subjective thinking is to discover or recreate for itself in its subjectivity. One understands the truth when thinking subjectivity is identical with the objective content. However, this identity is not one of substantial identity but formal only. In other words, subjective understanding and objective actuality may be the same in form but are essentially different in substance – one in the medium of thought, the other in the medium of being. A correspondence is merely assumed between these two. (shrink)

Many philosophers think the distinctive function of deontic evaluation is to guide action. This idea is used in arguments for a range of substantive claims. In this paper, we entirely do one completely destructive thing and partly do one not entirely constructive thing. The first thing: we argue that there is an unrecognized gap between the claim that the function of deontic evaluation is to guide action and attempts to put that claim to use. We consider and reject four arguments (...) intended to bridge this gap. The interim conclusion is thus that arguments starting with the claim that the function of deontic evaluation is to guide action have a lacuna. The second thing: we consider a different tack for making arguments of this sort work. We sketch a methodology one could accept that would do the trick. Unfortunately, as we’ll explain, although this methodology would bridge the gap in arguments that put claims about the function of deontic evaluation to work, it would do so in a way that vitiates any interest we might have in such arguments. As an aside, we’ll also point out how epistemologists, who have recently become interested in the function of epistemic evaluation, appear to already recognize this fact. The conclusion is hence a dilemma: either arguments from deontic function to substance have a lacuna or such arguments lack teeth. (shrink)

The purpose of this essay is to offer support for the substance view of persons, the philosophical anthropology defended by Patrick Lee in his essay. In order to accomplish this the author presents a brief definition of the substance view; argues that the substance view has more explanatory power in accounting for why we believe that human persons are intrinsically valuable even when they are not functioning as such, why human persons remain identical to themselves over time, (...) and why it follows from these points that the unborn are human persons; and responds to two arguments that attempt to establish the claim that the early human being is not a unified substance until at least fourteen days after conception.

In Galileo's Error, Philip Goff sets out a manifesto for a post-Galilean science of consciousness. Article four of the manifesto reads: 'Anti-Dualism: Consciousness is not separate from the physical world; rather consciousness is located in the intrinsic nature of the physical world.' I argue that there is an important sense of ‘dualism’ in which Goff’s arguments are not only compatible with but entail dualism, and not only dualism but substance dualism. Substance dualism, in the sense I have in (...) mind, is the view that (i) there are two sides to reality, a fundamentally mental side and a fundamentally nonmental side; and (ii) the fundamentally mental side consists of mental substances resembling Cartesian souls. I do not suggest that this is bad news for post-Galilean science of consciousness. My aim is rather to push for a certain view about what a theory of consciousness motivated by Goff’s arguments must look like. (shrink)

Kant’s argument in the First Analogy for the permanence of substance has been cast as consisting of a simple quantifierscope mistake. Kant is portrayed as illicitly moving from a premise such as (1) at all times, there must exist some substance, to a conclusion such as (2) some particular substance must exist at all times. Examples meant to show that Kant makes this mistake feature substances coming into and out of existence, but doing so at overlapping (...) times. I argue that Kant offers an argument against this kind of example in the following passage. Kant’s claim is that, were substances to be created and destroyed as in the example, the appearances would then be related to two different times, in which existence flowed side by side, which is absurd. For there is only one time, in which all different times must not be placed simultaneously but only one after another (A188–9/B231–32). (shrink)

Mind, Brain, and Free Will, Richard Swinburne’s stimulating new book, covers a great deal of territory. I’ll focus on some of the positions Swinburne defends in the philosophy of mind. Many philosophers are likely to have reservations about the arguments he uses to defend them, and others will think his basic position is unmotivated. My goal in this brief discussion is to articulate some of the reasons why.

The paper deals with the controversial issue of realism in Wittgenstein’s Tractatus. Most of the problems are grounded in the logical-linguistic foundation of important ontological notions given within the text (such as object, state of affairs, fact, etc.). This has led some scholars to think that there is no conception of the world in the Tractatus that is independent of language and that in his work Wittgenstein is simply engaged in a logical investigation of what it is essential for any (...) language to represent reality. Therefore, no conclusions about a transcendent world can be drawn from it. Here we argue that it is true that the author of the Tractatus is engaged in a logical investigation, conducted a priori and internal to language, on the conditions that are (or have to be) satisfied by any significant language. However, what such an investigation reveals, given one of these languages, is the necessity to presuppose a world made in a certain way and transcendent to the language that pretends to describe it. Two issues are considered to clarify the sense of the realism of the Tractatus — that of the existence of simple objects, and that of the truth of propositions — and a new interpretative schema for the text is advanced.

I discuss Peramatzis's (2011) argument that the form of a natural substance is essentially enmattered and so contains a material component.
