I here defend microphysical manyism. According to microphysical manyism, each composite or higher-level object is a mere plurality of microphysical particles. After clarifying the commitments of the view, I offer two physicalist-friendly arguments in its favour. The first argument appeals to the Canberra Plan. Here I argue that microphysical particles acting in unison play the theoretical roles associated with composite objects - that they do everything that we think of composite objects as doing - and thus that composite objects are (...) to be identified with pluralities of microphysical particles. Along the way I rebut the objections that pluralities of particles don’t display the right emergent, ‘lingering’, or modal properties to be good candidates for identification with higher-level objects. In the second argument I claim that microphysical manyism is uniquely able to capture a compelling and widespread physicalist intuition concerning the intimate nature of the relationship between higher-level, composite objects and the microphysical world.

The view that abstracta cannot exert causal power is pretty common in metaphysics. According to Friedell (2020), however, this view is mistaken. In a recent paper in this journal, he has argued that at least some abstracta are causally efficacious. My goal in what follows is to demonstrate that, given certain plausible methodological assumptions, Friedell 2020’s argument is not as strong as it might at first seem.

Setting aside all exclusion-style worries about the redundancy of postulating additional, non-physical mental causes for effects that can already be explained in purely physical terms, dualists who treat mental properties as supervening on physical properties still face a further problem: in cases of mental-to-mental causation, they cannot avoid positing an implausibly coincidental coordination in the timing of the distinct causal processes terminating, respectively, in the mental effect and its physical base. I argue that this problem arises regardless of whether one (...) treats the mental cause as causing both the mental effect and its physical base, or whether one treats the latter as having instead been caused by some physical state, and that the problem also does not depend on which theory of causation one adopts. A third option of treating the mental cause and its physical base as producing the mental effect and its physical base by a single causal process that they both contribute to is found to come up short as well.

One of the most popular arguments in favor of dualism is the zombie-conceivability argument. It is often argued that the possibility of zombies would entail that mental properties are epiphenomenal. This paper attempts to defuse the argument, offering a model of dualist mental causation which can serve as a basis for a modified, interactionist-friendly zombie argument.

Many philosophers take mental causation to be required for free will. But it has also been argued that the most popular view of the nature of mental states, i.e. non-reductive physicalism, excludes the existence of mental causation, due to what is known as the ‘exclusion argument’. In this paper, I discuss the difference-making account of mental causation proposed by [List, C., and Menzies, P. 2017. “My Brain Made Me Do It: The Exclusion Argument Against Free Will, and What’s Wrong with (...) It.” In H. Beebee, C. Hitchcock, & H. Price (eds.), Making a Difference: Essays on the Philosophy of Causation. Oxford Scholarship Online: Oxford University Press], who argue that their account not only solves the problem of causal exclusion but also saves free will. More precisely, they argue that it rebuts what they call ‘the Neurosceptical Argument’, the argument that if actions are caused by neural states and processes unavailable to us, there is no free will. I argue that their argument fails for two independent reasons. The first reason is that they fail to show that difference-makers are independent causes. The second reason is that physical realizers of mental states can be individuated in a way that makes both mental states and their realizers difference-makers. (shrink)

According to the so-called 'proportionality principle', causes should be proportional to their effects: they should be both enough and not too much for the occurrence of their effects. This principle is the subject of an ongoing debate. On the one hand, many maintain that it is required to address the problem of causal exclusion and take it to capture a crucial aspect of causation. On the other hand, many object that it renders accounts of causation implausibly restrictive and often reject (...) the principle wholesale. I argue that there is exaggeration on both sides. While one half of the principle is overly demanding, the other half is unobjectionable. And while the unobjectionable half does not block exclusion arguments on its own, it provides a nuanced picture of higher-level causation, fits with recent developments in philosophy of causation, and motivates adjustments to standard difference-making accounts of causation. I conclude that at least half of the proportionality principle is worth taking seriously. (shrink)

In this paper I argue that even the most radical metaphysics of powers (such as that adopted by Mumford & Anjum, Cartwright, or Groff) are compatible with eternalism. I first offer a taxonomy of powers ontologies, and attempt to characterise the difference between moderate and radical powers ontologies – the latter are characterised by an emphasis on production and dynamicity. I consider an argument by C. Friebe to the effect that the productive character of powers is inconsistent with Eternalism and (...) find it wanting. I then elucidate the notion of dynamicity that radical powers theorists employ by making apparent their link with an ontology of irreducible processes. Finally, I respond to an argument by Donatella Donati to the effect that eternalism entails a reductive account of change which is inconsistent with process ontologies, and show that the the two are compatible. I conclude that we have no reason to think that radical powers metaphysics (and, a fortiori, every powers ontology) are not compatible with eternalism. (shrink)

Agent-based virtue ethical theories must deal with the problem of right action: if an action is right just in case it expresses a virtuous motive, then how can an agent perform the right action but for the wrong reason, or from a vicious motive? Some recent agent-based accounts purport to answer this challenge and two other related problems. Here I assess these accounts and show them to be inadequate answers to the problem of right action. Overall, it is shown that (...) the most recent and promising attempts at squaring agent-based virtue ethics with commonsense morality are flawed, and so, the case for agent-basing in general that much dimmer.

The Exclusion Argument has afflicted non-reductionists for decades. In this article, I attempt to show that emergentism—the view that mental entities can downwardly cause physical entities in a non-overdetermining way—is the most plausible approach to solving the exclusion problem. The emergentist approach is largely absent in contemporary philosophy of mind, because emergentism rejects the Causal Closure of Physics, a doctrine embraced by almost all physicalists. This article, however, challenges the consensus on causal closure and defends a physicalist version of emergentism. (...) On closer examination, I find that neither physical evidence nor physicalist considerations can satisfactorily support causal closure. Moreover, I argue that two competing approaches that accept causal closure, compatibilism and autonomism, involve ad hoc postulations of mental causation. Therefore, all things considered, emergentism is the best option available to non-reductive physicalists. (shrink)

Many philosophers think all abstract objects are causally inert. Here, focusing on novels, I argue that some abstracta are causally efficacious. First, I defend a straightforward argument for this view. Second, I outline an account of object causation—an account of how objects cause effects. This account further supports the view that some abstracta are causally efficacious.

I argue that one’s views about which “metaphysical laws” obtain—including laws about what is identical with what, about what is reducible to what, and about what grounds what—can be used to deflect or neutralize the threat posed by a debunking explanation. I use a well-known debunking argument in the metaphysics of material objects as a case study. Then, after defending the proposed strategy from the charge of question-begging, I close by showing how the proposed strategy can be used by certain (...) moral realists to resist the evolutionary debunking arguments. (shrink)

Recently some philosophers suggested an exclusion problem for moral non-naturalism, which is similar to the exclusion problem in philosophy of mind. In this article, the author aims to advance the discussion of exclusion in morality by investigating two influential solutions to the exclusion problem: the autonomy solution and the overdetermination solution. The author attempts to show that the moral non-naturalist can solve the exclusion problem in a way that is different from the approach to solving mental-physical exclusion. First, the author (...) argues that while the autonomy solution to mental exclusion may work, a similar autonomy approach to moral exclusion is implausible. Second, the author argues that whereas the overdetermination solution to mental exclusion fails, a similar overdetermination solution to moral exclusion is promising. (shrink)

Composition as Identity is the view that an object is identical to its parts taken collectively. I elaborate and defend a theory based on this idea: composition is a kind of identity. Since this claim is best presented within a plural logic, I develop a formal system of plural logic. The principles of this system differ from the standard views on plural logic because one of my central claims is that identity is a relation which comes in a variety of (...) forms and only one of them obeys substitution unrestrictedly. I justify this departure from orthodoxy by showing some problems which result from attempts to avoid inconsistencies within plural logic by means of postulating other non-singular terms besides plural terms. Thereby, some of the main criticisms raised against Composition as Identity can be addressed. Further, I argue that the way objects are arranged is relevant with respect to the question which object they compose, i.e. to which object they are identical to. This helps to meet a second group of arguments against Composition as Identity. These arguments aim to show that identifying composite objects on the basis of the identity of their parts entails, contrary to our common sense view, that rearranging the parts of a composite object does not leave us with a different object. Moreover, it allows us to carve out the intensional aspects of Composition as Identity and to defend mereological universalism, the claim that any objects compose some object. Much of the pressure put on the latter view can be avoided by distinguishing the question whether some objects compose an object from the question what object they compose. Eventually, I conclude that Composition as Identity is a coherent and plausible position, as long as we take identity to be a more complex relation than commonly assumed. (shrink)

A popular response to the Exclusion Argument for physicalism maintains that mental events depend on their physical bases in such a way that the causation of a physical effect by a mental event and its physical base needn’t generate any problematic form of causal overdetermination, even if mental events are numerically distinct from and irreducible to their physical bases. This paper presents and defends a form of dualism that implements this response by using a dispositional essentialist view of properties to (...) argue that the psychophysical laws linking mental events to their physical bases are metaphysically necessary. I show the advantages of such a position over an alternative form of dualism that merely places more “modal weight” on psychophysical laws than on physical laws. The position is then defended against the objection that it is inconsistent with dualism. Lastly, some suggestions are made as to how dualists might clarify the contribution that mental causes make to their physical effects. (shrink)

How should ‘the physical’ be defined for the purpose of formulating physicalism? In this paper I defend a version of the via negativa according to which a property is physical just in case it is neither fundamentally mental nor possibly realized by a fundamentally mental property. The guiding idea is that physicalism requires functionalism, and thus that being a type identity theorist requires being a realizer-functionalist. In §1 I motivate my approach partly by arguing against Jessica Wilson's no fundamental mentality (...) constraint. In §2 I set out my preferred definition of ‘the physical’ and make my case that physicalism requires functionalism. In §3 I defend my proposal by attacking the leading alternative account of ‘the physical,’ the theory-based conception. Finally, in §4 I draw on my definition, together with Jaegwon Kim's account of intertheoretic reduction, to defend the controversial view that physicalism requires a priori physicalism. (shrink)

Sober and Elgin defend the claim that there are a priori causal laws in biology. Lange and Rosenberg take issue with this on Humean grounds, among others. I will argue that Sober and Elgin don’t go far enough – there are a priori causal laws in many sciences. Furthermore, I will argue that this thesis is compatible with a Humean metaphysics and an empiricist epistemology.

A commonly held view is that a central aim of metaphysics is to give a fundamental account of reality which refers only to the fundamental entities. But a puzzle arises. It is at least a working hypothesis for those pursuing the aim that, first, there must be fundamental entities. But, second, it also seems possible that the world has no foundation, with each entity depending on others. These two claims are inconsistent with the widely held third claim that the fundamental (...) just is the foundational. It is tempting to resolve the puzzle by rejecting the first or second claim, perhaps because it is obscure how the third claim might plausibly be challenged. But I develop a new analysis of fundamentality which challenges the third claim by allowing for an entity to be fundamental without being foundational. The analysis, roughly, is that an entity is fundamental just in case not all facts about it are grounded in facts about other entities. The possibility of fundamentality without foundations not only provides for a novel resolution to the puzzle, but has applications to some live debates: for example, it undermines Jonathan Schaffer's modal argument for priority monism.

Jaegwon Kim once refrained from excluding distinct mental causes of effects that depend upon the sufficient physical cause of the effect. At that time, Kim also refrained from excluding distinct mental explanations of effects that depend upon complete physical explanations of the effect. More recently, he has excluded distinct mental causes of effects that depend upon the sufficient cause of the effect, since the physical cause is individually sufficient for the effect. But there has been, to this point, no parallel (...) shift in the explanatory realm, such that distinct mental explanations of effects that depend upon complete physical explanations of the effect are excluded since the physical explanation is objectively complete. In this paper I consider, defend, and apply this update to the principle of explanatory exclusion—an update, which, in the final analysis, demonstrates a significant advantage that non-reductive physicalism has over reductive physicalism.

Semantic normativism, which is the view that semantic properties/concepts are some kind of normative properties/concepts, has become increasingly influential in contemporary meta-semantics. In this paper, I aim to argue that semantic normativism has difficulty accommodating the causal efficacy of semantic properties. In specific, I raise an exclusion problem for semantic normativism, inspired by the exclusion problem in the philosophy of mind. Moreover, I attempt to show that the exclusion problem for semantic normativism is peculiarly troublesome: while we can solve mental-physical (...) exclusion by adopting the so-called ‘autonomy approach’, a similar autonomy solution to semantic exclusion is implausible if semantic properties are understood as normative properties.

Widespread causal overdetermination is often levied as an objection to nonreductive theories of minds and objects. In response, nonreductive metaphysicians have argued that the type of overdetermination generated by their theories is different from the sorts of coincidental cases involving multiple rock-throwers, and thus not problematic. This paper pushes back. I argue that attention to differences between types of overdetermination discharges very few explanatory burdens, and that overdetermination is a bigger problem for the nonreductive metaphysician than previously thought.

This paper argues that the exclusion problem for mental causation can be solved by a variant of non-reductive physicalism that takes the mental not merely to supervene on, but to be grounded in, the physical. A grounding relation between events can be used to establish a principle that links the causal relations of grounded events to those of grounding events. Given this principle, mental events and their physical grounds either do not count as overdetermining physical effects, or they do so (...) in a way that is not objectionable. (shrink)

The physical realm is causally closed, according to physicalists like me. But why is it causally closed, what metaphysically explains causal closure? I argue that reductive physicalists are committed to one explanation of causal closure to the exclusion of any independent explanation, and that as a result, they must give up on using a causal argument to attack mind–body dualism. Reductive physicalists should view dualism in much the way that we view the hypothesis that unicorns exist, or that the Kansas (...) City Royals won the 2003 World Series: false, but not objectionable in any distinctively causal way. My argument turns on connections between explanation, counterfactuals, and inductive confirmation.

Suppose that Billy and Suzy each throw a rock at window, and either rock is sufficient to shatter the window. While some consider this a paradigmatic case of causal overdetermination, in which multiple cases are sufficient for an outcome, others consider it a case of joint causation, in which multiple causes are necessary to bring about an effect. Some hold that every case of overdetermination is a case of joint causation underdescribed: at a maximal level of description, every cause is (...) necessary to bring about the outcome in precisely the way that it occurs. -/- This paper shows the latter principle to be false. I introduce a novel class of events that are insensitive to the additive force of multiple causes. They are to be contrasted with sensitive events, which physically and counterfactually vary according to the number and sorts of causes they have. I argue that sensitive effects are symptoms of joint causation; insensitive effects are symptoms of overdetermination. Insensitive effects resulting from multiple causes cannot be classified as "joint causation underdescribed," but only as overdetermination. -/- I suggest that cases of "trumping preemption" should be understood as cases of overdetermination with insensitive effects. Consequently, Lewis' influence account of causation cannot handle these cases. (shrink)

In this dissertation, I argue that we should be pluralists about truth and in turn, eliminativists about the property Truth. Traditional deflationists were right to suspect that there is no such property as Truth. Yet there is a plurality of pluralities of properties which enjoy defining features that Truth would have, were it to exist. So although, in this sense, truth is plural, Truth is non-existent. The resulting account of truth is indebted to deflationism as the provenance of the suspicion (...) that Truth doesn't exist. But it would be hasty to simply classify the account as deflationary. Each of the 'truth-like' properties that it recognizes is highly substantive--that is, complex and explanatorily potent. So we should deflate Truth by recognizing that it doesn't exist, but we should also recognize that one of the most vital tasks in truth theory is to discover the essences of the many truth-like properties. My aim here is to do precisely this. (shrink)

Jaegwon Kim’s influential exclusion argument attempts to demonstrate the inconsistency of nonreductive materialism in the philosophy of mind. Kim’s argument begins by showing that the three main theses of nonreductive materialism, plus two additional considerations, lead to a specific and familiar picture of mental causation. The exclusion argument can succeed only if, as Kim claims, this picture is not one of genuine causal overdetermination. Accordingly, one can resist Kim’s conclusion by denying this claim, maintaining instead that the effects of the (...) mental are always causally overdetermined. I call this strategy the ‘ overdetermination challenge’. One of the main aims of this paper is to show that the overdetermination challenge is the most appropriate response to Kim’s exclusion argument, at least in its latest form. I argue that Kim fails to adequately respond to the overdetermination challenge, thus failing to prevent his opponents from reasonably maintaining that the effects of the mental are always causally overdetermined. Interestingly, this discussion reveals a curious dialectical feature of Kim’s latest response to the overdetermination challenge: if it succeeds, then a new, simpler and more compact version of the exclusion argument is available. While I argue against the consequent of this conditional, thereby also rejecting the antecedent, this dialectical feature should be of interest to philosophers on either side of this debate. (shrink)

The paper argues that dualism can explain mental causation and solve the exclusion problem. If dualism is combined with the assumption that the psychophysical laws have a special status, it follows that some physical events counterfactually depend on, and are therefore caused by, mental events. Proponents of this account of mental causation can solve the exclusion problem in either of two ways: they can deny that it follows that the physical effect of a mental event is overdetermined by its mental (...) and physical causes, or they can accept that the physical effect is overdetermined but claim that this is unproblematic because the case is sufficiently dissimilar to prototypical cases of overdetermination. (shrink)

The independence problems for functionalism stem from the worry that if functional properties are defined in terms of their causes and effects then such functional properties seem to be too intimately connected to these purported causes and effects. I distinguish three different ways the independence problems can be filled out – in terms of necessary connections, analytic connections and vacuous explanations. I argue that none of these present serious problems. Instead, they bring out some important and over-looked features of functionalism.

The 'completeness of physics' is the key premise in the causal argument for physicalism. Standard formulations of it fail to rule out emergent downwards causation. I argue that it must do this if it is tare in a valid causal argument for physicalism. Drawing on the notion of conferring causal power, I formulate a suitable principle, 'strong completeness'. I investigate the metaphysical implications of distinguishing this principle from emergent downwards causation, and I argue that categoricalist accounts of properties are better (...) equipped to sustain the distinction than dispositional essentialist accounts. Finally, I argue that the additional evidence needed for strong completeness renders the causal argument otiose for any properties amenable to scientific reduction. (shrink)

This paper motivates two bases for ascribing propositional semantic knowledge (or something knowledgelike): first, because it’s necessary to rationalize linguistic action; and, second, because it’s part of an empirical theory that would explain various aspects of linguistic behavior. The semantic knowledge ascribed on these two bases seems to differ in content, epistemic status, and cognitive role. This raises the question: how are they related, if at all? The bulk of the paper addresses this question. It distinguishes a variety of answers (...) and their varying philosophical and empirical commitments. (shrink)

The exclusion problem is held to show that mental and physical events are identical by claiming that the denial of this identity is incompatible with the causal completeness of physics and the occurrence of mental causation. The problem relies for its motivation on the claim that overdetermination of physical effects by mental and physical causes is objectionable for a variety of reasons. In this paper, I consider four different definitions of? overdetermination? and argue that, on each, overdetermination in all cases (...) of mental causation either does not occur or is unobjectionable, even when mental and physical events are non-identical. I therefore conclude that the exclusion problem cannot be used as a reason to accept that mental and physical events are identical unless some other definition of? overdetermination? is provided.

Particularists in material-object metaphysics hold that our intuitive judgments about which kinds of things there are and are not are largely correct. One common argument against particularism is the argument from arbitrariness, which turns on the claim that there is no ontologically significant difference between certain of the familiar kinds that we intuitively judge to exist (snowballs, islands, statues, solar systems) and certain of the strange kinds that we intuitively judge not to exist (snowdiscalls, incars, gollyswoggles, the fusion of the (...) my nose and the Eiffel Tower). Particularists frequently respond by conceding that there is no ontologically significant difference and embracing some sort of deflationary metaontology (relativism, constructivism, quantifier variance). I show -- by identifying ontologically significant differences -- that the argument can be resisted without retreating to any sort of deflationary metaontology. (shrink)

Several prominent attacks on the objects of 'folk ontology' argue that these would be omitted from a scientific ontology, or would be 'rivals' of scientific objects for their claims to be efficacious, occupy space, be composed of parts, or possess a range of other properties. I examine causal redundancy and overdetermination arguments, 'nothing over and above' appeals, and arguments based on problems with collocation and with property additivity. I argue that these share a common problem: applying conjunctive principles to cases (...) in which the claims conjoined are not analytically independent. This unified diagnosis provides a way of defending ordinary objects against these common objections, while also yielding warnings about certain uses of general conjunctive principles. (shrink)

Mereological nihilism is the view that all concrete objects are simple. Existence monism is the view that the only concrete object is one big simple: the world. I will argue that nihilism culminates in monism. The nihilist demands the simplest sufficient ontology, and the monist delivers it.

The paper argues that mental causation can be explained from the sufficiency of counterfactual dependence for causation together with relatively weak assumptions about the metaphysics of mind. If a physical event counterfactually depends on an earlier physical event, it also counterfactually depends on, and hence is caused by, a mental event that correlates with (or supervenes on) this earlier physical event, provided that this correlation (or supervenience) is sufficiently modally robust. This account of mental causation is consistent with the overdetermination (...) of physical events by mental events and other physical events, but does not entail it. (shrink)

Some theories are alleged to be implausible because they are committed to systematic ‘overdetermination’. In response, some authors defend ‘compatibilism’: the view that the putative overdetermination is benign, like other unproblematic cases of a single effect having many sufficient causes. The literature has tended to focus on the following question: which relations between sufficient causes of a single effect ensure that problematic overdetermination is avoided? This paper argues that several widely endorsed answers to this question are subject to counterexample. It (...) then proposes a diagnosis of this failure: the standard answers neglect what really matters––how the causes are connected to their shared effect. In particular, overdetermination is avoided when there are no independent causal connections. (shrink)

Some are attracted to the view that repeatable artworks, such as films, novels, plays, symphonies, photographs, and the like, are a particular kind of abstracta—namely, types. This view, however, is not unproblematic. One of the most serious problems it faces is the so-called "creation problem." The core idea behind this problem is that, on the one hand, it seems reasonable to accept the claims that (1) repeatable artworks are types, (2) types cannot be created, and (3) repeatable artworks are created, (...) but, on the other hand, these claims form an inconsistent triad. A popular solution to the creation problem is that (2) can be rejected because the justification for (2) is based on a false assumption—that no type can stand in causal relations. Although this solution looks promising, it can be accepted only if its proponent can refute what might be called the "paraphrasability argument." On this argument, types are not to be regarded as capable of standing in causal relations because any discourse implying the causality of types should be paraphrased into discourse that does not imply this. My aim in this essay is to show that there is good reason to consider the paraphrasability argument sound and, hence, that the foregoing solution to the creation problem fails. (shrink)

This paper investigates ‘exterminous hypertime’, a model of time travel in which time travellers can change the past in virtue of there being two dimensions of time. This paper has three parts. Part one discusses the laws which might govern the connection between different ‘hypertimes’, showing that there are no problems with overdetermination. Part two examines a set of laws that mean changes to history take a period of hypertime to propagate through to the present. Those laws are of interest (...) because: (i) at such worlds, a particular problem for non-Ludovician time travel (‘the multiple time travellers’ problem) is avoided; and (ii) they allow us to make sense of certain fictional narratives. Part three discusses how to understand expectations and rational decision making in a world with two dimensions of time. I end with an appendix discussing how the different theories in the metaphysics of time (e.g., tensed/tenseless theories and presentism/eternalism/growing block theory) marry up with exterminous hypertime.

Loewer (in: Physicalism and its discontents, 2001; Philos Phenomenol Res 65:655–663, 2002; in: Contemporary debates in philosophy of mind, 2007) has argued that the nonreductive physicalist should respond to the exclusion problem by endorsing the overdetermination entailed by their view. Kim’s (Physicalism, or something near enough, 2005; in: Contemporary debates in the philosophy of mind, 2007) argument against this reply is based on the premise that mental causation must be a productive relation in order to sustain human agency. In this (...) paper, I challenge the premise that mental causation is a productive relation by appealing to the underlying double prevention structure of the physiological mechanisms of human action. Since the causal pathways from an agent’s mental events to bodily movement involves an absence, mental causation is not productive. This places Kim in a troublesome dilemma in his debate with Loewer: either surrender mental causation or deny that causation is a productive relation. With the support offered for productive mental causation undermined, responses to the exclusion problem based on accepting overdetermination remain viable options for the nonreductive physicalist. (shrink)

This paper explores and defends the idea that mental properties and their physical bases jointly cause their physical effects. The paper evaluates the view as an emergentist response to the exclusion problem, comparing it with a competing nonreductive physicalist solution, the compatibilist solution, and argues that the joint causation view is more defensible than commonly supposed. Specifically, the paper distinguishes two theses of closure, Strong Closure and Weak Closure, two causal exclusion problems, the overdetermination problem and the supervenience problem, and (...) argues that emergentists can avoid the overdetermination problem by denying Strong Closure and respond to the supervenience problem by accepting the joint causation view.

Nonreductive physicalism faces serious problems regarding causal exclusion, causal heterogeneity, and the nature of realization. In this paper I advance solutions to each of those problems. The proposed solutions all depend crucially on embracing modal counterpart theory. Hence, the paper’s thesis: counterpart theory saves nonreductive physicalism. I take as my inspiration the view that mental tokens are constituted by physical tokens in the same way statues are constituted by lumps of clay. I break from other philosophers who have pursued this (...) line, however, in that I hold that constitution is identity. Much of the value of the comparison to statues and lumps is that it calls to mind the resources used to defend constitution-as-identity, most notably that of counterpart theory. Along the way, I discuss the virtues of a trope ontology, modal objections to token identity theories, the prospects of conditional analyses of causal powers, the subset account of realization, and the grounding problem. I also endorse a novel, empirical argument in favor of counterpart theory. (shrink)

A number of philosophers have argued that causation is not an objective feature of the microphysical world but rather is a perspectival phenomenon that holds only between “coarse-grained” entities such as those that figure in the special sciences. This view seems to pose a problem for arguments for physicalism that rely on the alleged causal completeness of physics. In this paper, I address this problem by arguing that the completeness of physics has two components, only one of which is causal. (...) These two components of completeness can be used in an argument for physicalism that is supported by strong inductive evidence even in the absence of microphysical causation. (shrink)

objects are standardly taken to be causally inert, but this claim is rarely explicitly argued for. In the context of his platonism about musical works, in order for musical works to be audible, Julian Dodd argues that abstracta are causally efficacious in virtue of their concrete tokens participating in events. I attempt to provide a principled argument for the causal inertness of abstracta by first rejecting Dodd’s arguments from events, and then extending and generalizing the causal exclusion argument to the (...) abstract/concrete distinction. For reasons of parsimony, if concrete tokens or instantiations of abstract objects account for all causal work, then there is no reason to attribute causal efficacy to abstracta, and thus reason to maintain their causal inertness. I then consider how one of the main arguments against causal exclusion, namely Stephen Yablo’s notion of “proportionality”, could be modified to support the causal efficacy of abstracta. I argue that from a few simple premises Yablo’s account in fact supports their causal inertness. Having a principled reason for the causal inertness of abstracta appears to entail that the musical platonist must admit that we never literally hear the musical work, but only its performances. I sketch a solution to this problem available to Dodd, so that the musical platonist can maintain that musical works are abstract objects and are causally inert while retaining their audibility.

The paper begins with the assumption that psychological event tokens are identical to or constituted from physical events. It then articulates a familiar apparent problem concerning the causal role of psychological properties. If they do not reduce to physical properties, then either they must be epiphenomenal or any effects they cause must also be caused by physical properties, and hence be overdetermined. It then argues that both epiphenomenalism and over‐determinationism are prima facie perfectly reasonable and relatively unproblematic views. The paper (...) proceeds to argue against Kim’s (Kim, 2000, 2005) attempt to articulate a plausible version of reductionism. It is then argued that psychological properties, along with paradigmatically causally efficacious macro‐properties, such as toughness, are causally inefficacious in respect of their possessor’s typical effects, because they are insufficiently distinct from those effects. It is finally suggested that the distinction between epiphenomenalism and overdeterminationism may be more terminological than real. (shrink)

Dispositional monists believe that all properties are essentially causal. Recently, an overdetermination argument has been proposed by Trenton Merricks to support nihilism about ordinary objects. I argue that this argument can be extended to target both nihilism about ordinary objects and nihilism about physical particles when dispositional monism is assumed. It implies that a philosopher who both endorses dispositional monism and takes seriously the overdetermination argument should not believe in the existence of physical particles. I end up by discussing possible (...) objections. I suggest, then, that if we live in a world that is inhabited by causal properties but not by chairs and tables, then we also live in a world without electrons and quarks, a world of dispositional properties, that is, a world of causal fields.

I argue that the Carroll-Chen cosmogonic model does not provide a plausible scientific explanation of our universe's initial low-entropy state.

The overdetermination problem has long been raised as a challenge to nonreductive physicalism. Nonreductive physicalists have, in various ways, tried to resolve the problem through appeal to counterfactuals. This essay does two things. First, it takes up the question whether counterfactuals can yield an appropriate notion of causal redundancy and argues for a negative answer. Second, it examines how this issue bears on the mental causation debate. In particular, it considers the argument that the overdetermination problem simply does not arise (...) on a dependency conception of causation and shows why this idea, though initially appealing, does not address the real problem. As the essay shows, the idea derives its spurious plausibility from the fact that the dependency conception cannot even make sense of our pretheoretic idea of causal redundancy. The essay concludes by briefly discussing a possible picture of mental causation that suggests itself in light of these results. (shrink)

Dualism holds that some mental events are fundamental and non-physical. I develop a prima facie plausible causal argument for dualism. The argument has several significant implications. First, it constitutes a new way of arguing for dualism. Second, it provides dualists with a parity response to causal arguments for physicalism. Third, it transforms the dialectical role of epiphenomenalism. Fourth, it refutes the view that causal considerations prima facie support physicalism but not dualism. After developing the causal argument for dualism and drawing (...) out these implications, I subject the argument to a battery of objections. Some prompt revisions to the argument. Others reveal limitations in scope. It falls out of the discussion that the causal argument for dualism is best used against physicalism as a keystone in a divide and conquer strategy. (shrink)

According to proponents of the causal exclusion problem, there cannot be a sufficient physical cause and a distinct mental cause of the same piece of behaviour. Increasingly, the causal exclusion problem is circumvented via this compatibilist reasoning: a sufficient physical cause of the behavioural effect necessitates the mental cause of the behavioural effect, so the effect has a sufficient physical cause and a mental cause as well. In this paper, I argue that this compatibilist reply fails to resolve the causal (...) exclusion problem. (shrink)
