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)

This is a book of new essays by different authors on physicalism. The essays are divided into three sections. In the first, the papers are, the editors say, “generally sympathetic” to physicalism. The opening paper, by Papineau, is a compelling historical discussion of the thesis of the completeness of physics, together with the suggestion that an appreciation of the empirical basis of this thesis led to the widespread acceptance of physicalism itself in the second part of the twentieth century. The (...) next two papers, by Loewer and Witmer, concern the formulation of physicalism, concentrating on questions of supervenience and determination. The next two papers, by Shoemaker and Rey, concern the connection between physicalism and mental causation. Shoemaker concentrates on George Bealer’s well-known argument that functionalism has the objectionable consequence that people routinely have beliefs about the realizers of their pains, but he places the discussion in a larger framework dealing with the notion of realization and mental causation. Rey’s paper is a vigorous discussion of those who view folk psychology as being insulated in an important theoretical sense, and hence as providing no causal explanations at all. The following paper, by Robinson, makes the point that contemporary discussion of nonreductive physicalism confuses two senses of ‘reduction’, one appropriate to philosophy of science and one to philosophy of mind. The penultimate paper in this part of the volume, by Latham, is an attempt to clarify the idea of token-physicalism, while the final paper is a fascinating attack by Leeds on the Kripkean notion of metaphysical necessity.

The so-called problem of mental causation as discussed in the recent literature raises three central challenges for an adequate solution from a physicalist perspective: the threat of epiphenomenalism, the problem of externalism (or the difficulty in accounting for the causal efficacy of extrinsic mental properties) and the problem of causal exclusion (or the threat of over determination). We wish to account for mental causationas a real phenomenon within a physicalistic framework without accepting epiphenomenalism or overdetermination. The key ideas of (...) our proposal are an internal realism of causation combined with a relative notion of individuating events. We are arguing?contra Davidson?tha there is no absolute notion of events (neither as types nor as tokens) but rather one which is relative to explanatory interests and our intuitions concerning a relevant spatial and temporal overlap. Furthermore, we are presupposing a metaphysics of internal realism: We can only characterize entities by means of concepts produced within our epistemological framework. Physical concepts and mental concepts crossclassify the world as it is. Relying on this framework we try to explain how mental causation can be adequately described: Although mental concepts are not reducible to physical concepts and mental event-tokens may be different from "underlying" physical event-tokens, mental events are real phenomena that are realized by physical phenomena in special context conditions.

Jeagwon Kim's exclusion argument is a well-known argument against non-reductive physicalism in the contemporary debate on mental causation. In this essay, we will first discuss two versions of the exclusion argument: the simple version and the sophisticated version. Secondly, we will take a conservative strategy to defend the kind of non-reductive physicalism initiated by Donald Davidson: the Token Identity Theory. Namely, we will explain where Kim failed to appropriately understand Davidson's work and argue that the simple version and the sophisticated (...) version of the exclusion argument won't work against the clarified token identity theory at all. Lastly, Since much of Kim's inappropriate interpretation of Davidson's work is rooted in their difference in metaphysics, there is reason to believe the proper understanding and evaluation on contemplation as such on mental causation, non-reductive physicalism, and other related problems can't be achieved without finding an appropriate metaphysical frame.

Physicalism, a topic that has been central to modern philosophy of mind and metaphysics, is the philosophical view that everything in the space-time world is ultimately physical. The physicalist will claim that all facts about the mind and the mental are physical facts and deny the existence of mental events and state insofar as these are thought of as independent of physical things, events and states. This collection of essays, first published in 2001, offers a series of perspectives (...) on this important doctrine and brings depth and breadth to the philosophical debate. A group of distinguished philosophers, comprising both physicalists and their critics, consider a wide range of issues including the historical genesis and present justification of physicalism, its metaphysical presuppositions and methodological role, its implications for mental causation, and the account it provides of consciousness.

Token physicalism is often viewed as a modest and unproblematic physicalist commitment, as contrasted with type physicalism. This paper argues that the prevalence of functional individuation in biology creates serious problems for token physicalism, because the latter requires that biological entities can be individuated physically and without reference to biological functioning. After characterizing the main philosophical roles for token physicalism, I describe the distinctive uses of functional individuation in models of biological processes. I then introduce some requirements on token (...) identity claims that arise from a position on individuation and identity known as sortalism. An examination of biological examples shows that these sortalist requirements cannot be plausibly met due to differences between individuation by functional biological criteria and by physical criteria. Even without assuming sortalism, token physicalism faces the more basic problem of excluding functionally irrelevant detail from the individuation of biological tokens. I close by suggesting that the philosophical roles for token identity are better fulfilled by a notion of token composition, which promotes a hierarchical picture of individuality. (shrink)

Many theorists have contended that since the mind depends on the brain, the contents of our thoughts are determined by just the intrinsic physical properties of our bodies. In the first part of my dissertation I examine this theory's negation, anti-individualism, by investigating the "Twin-Earth" thought experiments of Putnam and Burge. Although anti-individualism has recently become widely accepted, I argue that none of the arguments given thus far are sound; nor has the theory been given a proper formulation. I also (...) argue that no one has articulated an interesting and true version of externalism, the related idea that if one is thinking, for example, that water is wet, then one's environment has certain empirical features . However, I then proceed to present a true version of externalism and a sound argument for a version of anti-individualism. ;In the past few years many theorists have argued that the Twin-Earth arguments, if they prove anything, have stunning implications: they refute physicalism, scepticism, authoritative self-knowledge, and the causal construal of psychological explanation; and they show that the contents of our thoughts that are appealed to in ordinary psychological explanation are not the contents captured by the sentences we use in those explanations. I attempt to refute all these arguments. ;In the second part of the dissertation I argue against the thesis that thought and action tokens exist and are, at bottom, physical entities. Roughly put, one of the main premises of the main argument is that if an action token has a physical makeup then there cannot be radically incompatible but equally plausible proposals regarding what that makeup is; but since there are such proposals, the tokens have no physical makeup. I then formulate a naturalist but nonphysicalist view of mental tokens. (shrink)

In The Bodhisattva’s Brain: Buddhism Naturalized, Owen Flanagan undertakes a project of what he calls ‘cosmopolitan philosophy’, with an aim to develop and interrogate a naturalized Buddhism. A project of naturalization requires a conception of naturalism that can serve as a hermeneutic and philosophical standard against which certain things may be judged naturalistically acceptable or unacceptable. On Flanagan’s account, Buddhism ‘naturalized’ is primarily a Buddhism, “without the mind-numbing and wishful hocus-pocus.” Instead, he sets out to sketch a version of Buddhism (...) (or a new view inspired by it) that is consistent with neo-Darwinian evolutionary theory and scientific materialism, including ‘neurophysicalism’ or the view that “mental events are brain events.” However, classical Buddhist philosophers rejected materialism on philosophical, not merely dogmatic, grounds. In contemporary terms, Buddhist philosophers saw that phenomenal consciousness, intentionality, and mental causation present serious problems for materialism. So, rather than dismissing Buddhist anti-materialist accounts of mind as simply ‘hocus-pocus’, in this chapter takes up the question of whether and how these views might inform a naturalistic Buddhist philosophy. The question, then, is whether a naturalistic Buddhism requires some form of neurophysicalism. It is argued that it does not, by way of examining two distinct versions of naturalistic, but non-physicalist accounts of consciousness reconstructed from the Indian Buddhist tradition. The first, drawing on the work of Dharmakīrti, is a form of trope dualism. The second, drawing on the work of Śāntarakṣita, is a form of pragmatic pluralism that gives a central place to consciousness. And while these two accounts are distinct, and in some important respects incompatible, what they have in common is the idea that consciousness is both non-physical and fully natural. (shrink)

The distinction between token and type physicalism is a familiar feature of discussion of psychophysical relations. Token physicalism, or ontological physicalism, is the view that every token, or particular, in the spatiotemporal world is a physical particular. It is contrasted with type physicalism, or property physicalism -- the view that every first-order type, or property, instantiated in the spatiotemporal world is a physical property. Token physicalism is commonly viewed as a clear thesis, strictly weaker than property physicalism, strictly (...) stronger than substance physicalism, and as a good statement on its own or in conjunction with other theses of minimal physicalism.[i] It is also generally simply assumed to be true, though Davidson has offered a famous argument for its truth, and some have argued against it. Many of those arguing against it are substance physicalists, indicating that they believe token physicalism to be a strictly stronger view.[ii]. (shrink)

It has become evident that mind–body supervenience, as merely specifying a covariance between mental and physical properties, is consistent with clearly non-physicalist views of the mental, such as emergentism. Consequently, there is a push in the physicalist camp for an ontologically more robust supervenience, a “superdupervenience,” that ensures that properties supervening on physical properties are physicalistically acceptable. Jessica Wilson claims that supervenience is made superduper by Condition on Causal Powers (CCP): each individual causal power associated with a supervenient (...) property is numerically identical with a causal power associated with its base property. Furthermore, according to Wilson, a wide variety of physicalist positions, both reductive and non-reductive, can be seen as relying on CCP to ensure that properties supervening on physical properties are physicalistically acceptable. I argue that imposing CCP on mind–body supervenience fails to ensure that mental properties are physicalistically acceptable. The problem, I contend, is that while CCP may guard against supervenient mental properties being insufficiently grounded in their physical bases it fails to guard against supervenient mental properties being too deeply grounded in their physical bases.

Mental events enter into causal relations with bodily events. The philosophical task is to explain how this is possible. Descartes’ dualism of mental and material substances ultimately founders on the impossibility of pairing mental events with physical events as causes and effects. This is what I have called “the pairing problem.” Many contemporary views also fail to explain mental causation. In the end, we are left with a dilemma. If mental phenomena are irreducible to physical phenomena, then mental phenomena lose (...) their causal efficacy. However, if mental phenomena are reducible to physical phenomena, then casts doubt on the very existence of mental phenomena. (shrink)

Although physicalism has been the dominant position in recent work in the philosophy of mind, this dominance has not prevented a small but growing number of philosophers from arguing that physicalism is untenable for several reasons: both ontologically and epistemologically it cannot reduce mentality to the realm of the physical, and its attempts to reduce subjectivity to objectivity have thoroughly failed. The contributors to After Physicalism provide powerful alternatives to the physicalist account of the human mind from a dualistic (...) point of view and argue that the reductive and naturalistic paradigm in philosophy has lost its force. The essays in this collection all firmly engage in a priori metaphysics. Those by Uwe Meixner, E. J. Lowe, John Foster, Alvin Plantinga, and Richard Swinburne are concerned with ways to establish the truth of dualism. Essays by William Hasker, A. D. Smith, and Howard Robinson deal with the relation between physicalism and dualism. Benedikt Paul Göcke argues that the “I” is not a particular and Stephen Priest that “I have to understand myself not as a thing but as no-thing-ness.” In the final essay, Thomas Schärtl argues that there are limits to dualism as indicated by the concept of resurrection. By including two classical essays by Plantinga and Swinburne, the volume conveniently brings together some of the best and the newest thinking in making the philosophical case for dualism. "Seven of these essays are by eminent philosophers: Lowe, Foster, Plantinga, Swinburne, Hasker, Smith, and Robinson, each recapitulating his well-known position in the debate. To have these seven essayists together under one cover constitutes a remarkable book, which can be used as a textbook in philosophy of mind as well as in philosophy of religion courses, and which also opens up the debate in an original way among colleagues at an advanced level." —Fergus Kerr, University of Edinburgh.

This is a 6,000 word encyclopedia entry, intended to be accessible to students, on physicalism when it is understood, narrowly, as the view that people’s mental properties are nothing over and above—nothing additional to—their physical properties.

Content externalism is the dominant view in the philosophy of mind. Content essentialism, the thesis that thought tokens have their contents essentially, is also popular. And many externalists are supporters of such essentialism. However, endorsing the conjunction of those views either (i) commits one to a counterintuitive view of the underlying physical nature of thought tokens or (ii) commits one to a slightly different but still counterintuitive view of the relation of thought tokens to physical tokens as (...) well as a rejection of realist physicalism. In this essay I reveal the problem and articulate and adjudicate among the possible solutions. I will end up rejecting content essentialism. (shrink)

Libertarian free will is, roughly, the view that the same agential states can cause different possible actions. Nonreductive physicalism is, roughly, the view that mental states cause actions to occur, while these actions also have sufficient physical causes. Though libertarian free will and nonreductive physicalism have overlapping subject matter, and while libertarian free will is currently trending at the same time as nonreductive physicalism is a dominant metaphysical posture, there are few sustained expositions of a nonreductive physicalist (...) model of libertarian free will – indeed some tell against such an admixture. This paper concocts such a blend by articulating and defending, with some caveats, a nonreductive physicalist model of libertarian free will. (shrink)

The dominant way to define physical entities is by appeal to ideal physics (as opposed to current physics). However, it has been worried that physicalism understood in terms of ideal physics would be too liberal to rule out “psychism”, the view that mentality exists at the fundamental metaphysical level. In this article, I argue that whereas physicalism is incompatible with some psychist cases, such as the case of “phenomenalism” in which ideal physics adopts mental concepts to denote fundamental entities, (...) physicalism should accommodate a certain type of psychist case in which fundamental mental entities are denoted by non-mental concepts in ideal physics. In so doing, I propose a distinctive account of physical entities, which asserts that physical entities are entities denoted by non-mental natural concepts in ideal physics. Physicalism thus understood is expected to be neither too liberal nor too demanding. (shrink)

This paper presents and discusses the most influential attempts to characterize physicalism without postulating relations of identity between the physical and the prima facie non-physical. The first section deals with a possible criticism that these attempts are misguided, since they contradict the physicalist slogan “everything there is physical.” In the second section, I elucidate the different formulations of the physicalist supervenience claim, and argue that none of them consists in an adequate characterization of physicalism. Three reasons are given (...) in favor of this conclusion: their compatibility with forms of dualism ; the fact that the supervenience relation is left unexplained; and Kim’s causal exclusion argument, which asserts that merely supervenient entities must be epiphenomenal. The third section presents the general features of another identity-independent attempt to characterize physicalism, namely realization physicalism. According to this view, tokens of prima facie non-physical types are realized by tokens of strictly physical types performing functional roles that specify the nature of the former. The third section also shows how realization physicalism deals with the objections that make physicalist supervenience claims inadequate for characterizing physicalism. Resumo O artigo apresenta e discute as tentativas mais influentes de caracterizar o fisicalismo sem postular relações de identidade entre o que é físico e o que é prima facie não físico. A primeira seção trata da possível crítica de que essas tentativas são equivocadas, porque contradizem o bordão fisicalista “tudo o que existe é físico”. Na segunda seção, elucido as diferentes formulações da tese fisicalista da superveniência, e argumento que nenhuma delas consiste em uma caracterização adequada do fisicalismo. Três razões são oferecidas em favor dessa conclusão: sua compatibilidade com formas de dualismo ; o fato de que a relação de superveniência é mantida sem explicação; e o argumento de Kim da exclusão causal, segundo o qual entidades meramente supervenientes devem ser epifenomenais. A terceira seção apresenta os aspectos gerais de outra tentativa de caracterizar o fisicalismo independente da identidade, a saber, o fisicalismo de realização. De acordo com essa posição, ocorrências de tipos prima facie não físicos são realizadas por ocorrências de tipos físicos quando estes executam os papéis funcionais que especificam a natureza dos primeiros. A terceira seção também revela como o fisicalismo de realização lida com as objeções que tornam as teses fisicalistas da superveniência inadequadas para a caracterização do fisicalismo. (shrink)

Late twentieth-century physicalism—here understood, broadly, as a comprehensive view about the nature of contingent reality, rather than, narrowly, as a view about the relation of the mental to the physical—is widely regarded as the descendant of the materialist hypotheses familiar from the history of philosophy both ancient and modern. This chapter contends that contemporary physicalism differs significantly from historical hypotheses of materialism, significantly enough that the prospects for physicalism cannot be inferred from those for materialism. The chapter brings (...) out these differences by identifying the two main challenges faced by philosophers who want to revive the materialist hypotheses of earlier centuries, and then indicating the author’s possibly idiosyncratic view of how these challenges are best overcome. The first challenge is to formulate physicalism adequately, so that it is interesting but neither obviously true nor obviously false; the second challenge is to specify what would count as empirical evidence for an adequately-formulated hypothesis of physicalism. The chapter’s survey of responses to these two challenges constitutes an opinionated history of central aspects of the past fifty (or so) years of philosophical reflection on physicalism. (shrink)

Most philosophers of mind nowadays espouse two metaphysical views: Nonreductive Physicalism and the causal efficacy of the mental. Throughout this work I will refer to the conjunction of both claims as the Causal Autonomy of the Mental. Nevertheless, this position is threatened by a number of difficulties which are far more serious than one would imagine given the broad consensus that it has generated during the last decades. This paper purports to offer a careful examination of some of these difficulties (...) and show the considerable efforts that one has to undertake in order to try to overcome them. The difficulties examined will concern only metaphysical problems common to all special science properties but not specific of mental properties. So, in proposing a functionalist version of Nonreductive Physicalism in what follows, I will not attempt to answer to well known objections such as the absent qualia argument and the like. This should not be interpreted as a limitation! in the scope of this work. On the contrary, in dealing with more general objections we will try to evaluate a position which entails (under common assumptions) the Causal Autonomy of the Mental, namely: Nonreductive Physicalism plus the causal efficacy of special science properties.

The issue of materialism has recently been raised again. Mr. Putnam argues against philosophical behaviorism [4]. Such a position holds, as he construes it, that statements like ‘Jones is angry’ can be analyzed in solely behavioral terms. When one argues against philosophical behaviorism, he might be expected to distinguish this metaphysical position from behavior science. Putnam, however, does not make the distinction. Consequently he argues against both. I shall first state the distinction between these two different things, namely, philosophical behaviorism (...) and behavior science, as I see it. The behavior scientist adopts the thesis that in principle it is possible to predict future behavior on the basis of data concerning environmental, behavioral, and physiological variables. All three of these he considers in physical terms. The behavior scientist thus speaks about physical objects and properties of such. Talking in such terms, he believes that it is in principle possible to coordinate to statements asserting that person X has or is in state of mind Y another statement, employing only the above mentioned physical terms, such that either both are true or both are false. The reasons for the behavior scientist's program are the well known quandaries involved in the observation of other people's minds and the need for intersubjective verification in science. One can further distinguish between a narrower and a broader view of behavior science. The former restricts itself to environmental and behavioral variables at what some call the macro level; the latter includes, or even concentrates upon, physiological variables. As scientists neither the behaviorist nor the physiologist asks or answers philosophical questions, either epistemological or ontological, about minds, bodies, and mental contents. (shrink)

In his introduction to Philosophical Naturalism, Papineau mentions that he had intended, at one time, to call the book Philosophical Physicalism. In the end, he writes, he rejected that title, partly for fear that the term "physicalism" might have suggested commitment to a metaphysical position tied closely to the ontology and categories dictated by current physics, a commitment he is anxious not to incur; and partly because the concerns of the book as a whole are wider than would have been (...) suggested by the rejected title. Nevertheless, the early chapters of the book make it clear that the first choice of title would have been, in some ways, a more accurate guide to the character of Papineau's convictions about a number of central issues in metaphysics, philosophy of science and philosophy of mind. Specifically, Papineau's views about the relationships between what he calls "the special" and the physical in general, and between the psychological and the physical in particular, fall into a sector of naturalist territory that is indisputably physicalistic. I shall concentrate here on two lines of thought from these early chapters: the first, Papineau's characterisation of physicalism, by means of the two doctrines he calls "supervenience" and "token congruence", in Chapter 1; the second, a puzzle he raises in Chapter 2 for those who are content with a physicalism sufficiently weak to allow for variable realisation.

Our minds have physical effects. This happens, for instance, when we move our bodies when we act. How is this possible? Thomas Kroedel defends an account of mental causation in terms of difference-making: if our minds had been different, the physical world would have been different; therefore, the mind causes events in the physical world. His account not only explains how the mind has physical effects at all, but solves the exclusion problem - the problem of how those effects can (...) have both mental and physical causes. It is also unprecedented in scope, because it is available to dualists about the mind as well as physicalists, drawing on traditional views of causation as well as on the latest developments in the field of causal modelling. It will be of interest to a range of readers in philosophy of mind and philosophy of science. This book is also available as Open Access. (shrink)

Regardless of whatever else physicalism requires, nearly all philosophers agree that physicalism cannot be true in a world which contains fundamental mentality. I challenge this widely held attitude, and describe a world which is plausibly all-physical, yet which may contain fundamental mentality. This is a world in which priority monism is true—which is the view that the whole of the cosmos is fundamental, with dependence relations directed from the whole to the parts—and which contains only a single mental system, (...) like a brain or computer. Because some properties of the whole are fundamental under priority monism, it follows that that the mental properties of a cosmos-encompassing brain or computer system may be fundamental in a priority monist world. Yet such a world need not contain anything physically unacceptable: the mental properties of the cosmos-encompassing brain or computer can be characterized in a physicalism-friendly functionalist or identity-theoretic way. Thus, as I see it, physicalism need not be false in such a world. This constitutes a challenge to those who hold the view that physicalism is inconsistent with the existence of fundamental mentality. (shrink)

The doctrine of physicalism can be roughly spelled out simply as the claim that the physical state of the world determines the total state of the world. However, since there are many forms of determination, a somewhat more precise characterization is needed. One obvious problem with the simple formulation is that the traditional doctrine of epiphenomenalism holds that the mental is determined by the physical (and epiphenomenalists need not assert that there are any properties except mental and physical ones, so (...) one can freely add to epiphenomenalism the claim that everything is determined by the physical state of the world). However, the orthodox view, which seems obviously correct, is that physicalists would and should balk at the claim that epiphenomenalism is a form of physicalism. The philosophical zombie thought experiment vividly reveals exactly why epiphenomenalism is not a version of physicalism. According to traditional epiphenomenalism the determination relation in question is causation, and causal relations do not hold with full necessity. They hold with at most nomological necessity. Thus there is a possible world, w, in which the causal laws (or, if one prefers a more Humean approach, where the cosmic regularities) are different in such a way that the physical states which in the actual world cause mental states either cause no mental states at all in w (the zombie option) or cause aberrant mental states (the inverted spectrum option). Why should the physicalist care about this ‘mere possibility’? Because it shows that the mental can vary independently of the physical and there can be no better demonstration of ontological distinctness 1 than independent variation. Therefore, physicalism requires that the sort of determination at issue must exhibit maximum modal force; it must be absolutely impossible for the mental to vary without attendant, determining physical variation (let us label this relation ‘logical determination’). I think the best way to state physicalism which meets this constraint is in terms of what are called minimal physical duplicates (MPDs) of possible worlds (an approach pioneered by David Lewis, see Lewis (1983b); see also Jackson (1998) and Chalmers and Jackson (2001))..

This paper identifies and critiques a theory of mental causation defended by some proponents of nonredutive physicalism that I call “intralevelism.” Intralevelist theories differ in their details. On all versions, the causal outcome of the manifestation of physical properties is physical and the causal outcome of the manifestation of mental properties is mental. Thus, mental causation on this view is intralevel mental to mental causation. This characterization of mental causation as intralevel is taken to insulate nonreductive physicalism from some (...) objections to nonreductive physicalism, including versions of the exclusion argument. This paper examines some features of three recent versions of intralevelism defended by John Gibbons, Markus Schlosser, and Amie Thomasson. This paper shows that the distinctive problems faced by these three representative versions of intralevelism suggest that the intralevelist strategy does not provide a viable solution to the exclusion problem.

Even if cognitive science has made some important progress in its approach to human mental activities, consciousness and subjective experience still strike us as highly puzzling from a 'scientific' point of view. This may not be surprising, since the Cartesian distinction between res cogitans and res extensa seems to have a priori ruled out the very possibility of understanding the human mind as an object of physical science. However, in this paper, I argue that some Cartesian intuitions about the (...) nature of consciousness may still deserve sustaining by showing that it is a mistake to seek some physicalist reduction of the phenomena of consciousness. At the same time, I also try to show in what sense Colin McGinn's transcendental naturalism may be intelligible. (shrink)

Quine's views on ontology and naturalism are well-known but rarely considered in tandem. According to my interpretation the connection between them is vital. I read Quine as a global epistemic structuralist. Quine thought we only ever know objects qua solutions to puzzles about significant intersections in observations. Objects are always accessed descriptively, via their roles in our best theory. Quine's Kant lectures contain an early version of epistemic structuralism with uncharacteristic remarks about the mental. Here Quine embraces mitigated anomalous monism, (...) allowing introspection and the availability in principle of full physical descriptions of the perceptual states which get science off the ground. Later versions abandon these ideas. My epistemic-structural interpretation explains why. I argue first-personal introspective access to mental states is incompatible with global epistemic structuralism. (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.

In this paper, I discuss a view proposed by Carl Hempel in his paper Reduction: Ontological and Linguistic Facets, published in 1969. Here, Hempel suggested that questions regarding the identification of mental states with physiological states, the relation between sociological phenomena and individual behavioral states, and between biological and physicochemical states should be given what he calls a ‘linguistic’ interpretation. His main point is that whether or not an object is physical or biological depends on how it is, or (...) can be, described. In this paper, I wish to, firstly, explicate Hempel's suggestion, and, secondly, explore one argument in favor of Hempel's account. I will suggest that there is at least one use of the term ‘physical’ in philosophical discourse (and, for that matter, of related terms such as ‘biological’, ‘mental’, ‘natural’ etc.) that should be cashed out in linguistic or representational terms.

Some philosophers argue that mental properties are ontologically distinct from physical properties and that, therefore, physicalism ought to be rejected. There are philosophers who feel the force of this challenge but who wish to maintain their physicalism. They suggest that mentality is grounded in inscrutable properties or ‘incrutables’: properties that are not revealed through physical enquiry but that do not violate physicalism. Our analysis reveals that appealing to inscrutables is not a successful strategy for these physicalists, for the following reasons: (...) first, inscrutables likely do violate the conditions of physicalism; second, inscrutables lend greater support to panpsychism than physicalism; third, there is good reason to be agnostic as to whether or not inscrutables count as physical properties. Each of these reasons undermines the physicalist’s purpose in positing inscrutables. If one wishes to remain a physicalist, they ought to direct their philosophical analysis and energies toward revisiting and defeasing the arguments that purport to show that mental properties are ontologically distinct from physical properties.

Throughout the 1990s, Jaegwon Kim developed a line of argument that what purport to be nonreductive forms of physicalism are ultimately untenable, since they cannot accommodate the causal efficacy of mental states. His argument has received a great deal of discussion, much of it critical. We believe that, while the argument needs some tweaking, its basic thrust is sound. In what follows, we will lay out our preferred version of the argument and highlight its essential dependence on a causal-powers metaphysic, (...) a dependence that Kim does not acknowledge in his official presentations of the argument.i We then discuss two recent physicalist strategies for preserving the causal efficacy of the mental in the face of this sort of challenge, strategies that (ostensibly) endorse a causal powers metaphysics of properties while offering distinctive accounts of the physical realization of mental properties. We argue that neither picture can be satisfactorily worked out, and that seeing why they fail strongly suggests that nonreductive physicalism and a causal powers metaphysic are not compatible, as our original argument contends. Since we also believe that robust realism concerning mental causation should not be abandoned, we take the argument of this paper to strongly motivate an account on which the mental is unrealized by and ontologically emergent from the physical. In a final section, we sketch what an ontologically emergentist account of the mental might look like. (shrink)

Samuel Alexander was one of the foremost philosophical figures of his day and has been argued by John Passmore to be one of ‘fathers’ of Australian philosophy as well as a novel kind of physicalist. Yet Alexander is now relatively neglected, his role in the genesis of Australian philosophy if far from widely accepted and the standard interpretation takes him to be an anti-physicalist. In this paper, I carefully examine these issues and show that Alexander has been badly, (...) although understandably, misjudged by most of his contemporary critics and interpreters. Most importantly, I show that Alexander offers an ingenious, and highly original, version of physicalism at the heart of which is a strikingly different view of the nature of the microphysical properties and associated view of emergent properties. My final conclusion will be that Passmore is correct in his claims both that Alexander is significant as one of the grandfather’s of Australian philosophy and that he provides a novel physicalist position. I will also suggest that Alexander’s emergentism is important for addressing the so-called ‘problem of mental causation’ presently dogging contemporary non-reductive physicalists. (shrink)

Mental causation occurs when mental entities cause other mental and physical entities: seeings causing believings, itches causing scratchings, headaches causing eye twitches, and so on. The term “mental causation” is most often used to refer to the problem of mental causation, which is really a collection of problems with each possessing its own character and tradition of debate. The problem of mental causation began in earnest with an objection to Cartesian dualism raised by Princess Elizabeth of Bohemia (how can immaterial (...) minds causally interact with material bodies?) and still persists via a series of different objections raised against various views including non-reductive physicalism, anomalous monism, and psychological externalism. What unites the different problems of mental causation is their attempt to address a question of this general form: is model x of the non-causal mental-physical relationship (e.g., non-reductive physicalism) consistent with there being mental causation? A negative answer is usually taken to constitute a fatal objection to model x, but not always. There have been two major avenues of inquiry since Elizabeth’s original objection began the debate: (a) what theories of causation can tell us about the consistency of model x with mental causation; or (b) what theories about the non-causal mental-physical relationship can tell us about the consistency of model x with mental causation. Nearly every contribution in the literature on the problem of mental causation can be understood as belonging in either category (a) or (b), or as containing distinguishable elements which so belong. The most important discussions about mental causation have taken place over the last few decades, hence this entry will focus largely on work conducted in that period. Mental causation is also discussed in other areas of philosophy, such as political philosophy or ethics, but this entry will be primarily concerned with the metaphysical and philosophy of mind literature.

This paper focuses some aspects of a debate which took place between Donald Davidson and Jaegwon Kim, about the problem of causal efficacy of mental properties in the physical world. The most famous expression of davidsoniannon reductive physicalism, the argument of Anomalous Monism, was criticized by Kim, because it tries to harmonize two allegations that can´t coexist in a physicalist thesis, and have to be considered as incompatible from a physicalistpoint of view. The first of these allegations is (...) theAnomaly of the Mental, whichdefines the mental as autonomous from the system of laws that rule physical phenomena. The second allegation is that mental events and human actions are part of causal flow of natural events. Anomalous Monism seems to be an epiphenomenalist thesis, because, in Anomalous Monism, anomaly of the mental rules out causal efficacy of the mental in physical world. (shrink)

Nonreductive physicalism is currently one of the most widely held views about the world in general and about the status of the mental in particular. However, the view has recently faced a series of powerful criticisms from, among others, Jaegwon Kim. In several papers, Kim has argued that the nonreductivist's view of the mental is an unstable position, one harboring contradictions that push it either to reductivism or to eliminativism. The problems arise, Kim maintains, when we consider the (...) causal powers that mental properties are held to carry on the nonreductivist's view and the causal transactions into which mental events are said to enter. My aim here is less than that of defending nonreductive physicalism against all of Kim's criticisms. I wish primarily to call into question the claim that nonreductive physicalism is committed to emergentism with respect to the causal powers of the mental. As subsidiary points, I shall offer a limited defense of nonreductivism against two related objections that Kim raises. However, even if my conclusions are correct, problems remain for the nonreductivist's treatment of mental causation. I shall close the paper with a brief discussion of these difficulties. (shrink)

Nonreductive physicalists endorse autonomous mental causation, the view that mental causes, as distinct from physical causes, bring about mental and physical effects. The causal exclusion problem has recently pressured nonreductive physicalists to replace autonomous mental causation with reduced mental causation, the view that mental causes, as physical causes, bring about mental and physical effects. Reduced mental causation, in turn, faces the problem of mental quausation, according to which reduced mental causation only delivers mental‐as‐physical causation, not the requisite mental‐as‐mental (...) causation. Proponents of reduced mental causation have responded by emphasizing the success of reduction in delivering mental causation, while questioning the metaphysical legitimacy of mental quausation (Tiehen, 2019; Gibb, 2017; Robb, 2017; 2013).1 In this paper, I argue that the requirement for mental quausation not only withstands these objections, but that mental quausation is an inevitable problematic for any version of reduced mental causation.

Theo C. Meyering, in “Mind Matters: Physicalism and the Autonomy of the Person,” takes yet a third approach to the issue of reduction. He states that “if (true, downward) mental causation implies nonreducibility [as Stoeger and Murphy argue] and physicalism implies the converse, it is hard to see how these two views could be compatible.” Meyering distinguishes three versions of reductionism: radical (industrial strength) physicalism; ideal (regular strength) physicalism, and mild or token physicalism. Radical physicalism asserts that all special sciences (...) are reducible to physics in the sense that their laws can be deduced via bridge laws from those of physics. Ideal physicalism asserts that while it is practically impossible to reduce the special sciences, such reduction would be possible were there an ideally complete physics" (Note: This distinction parallels Stoeger’s recognition that epistemological reducibility is relative to the meaning of “laws of nature). Token physicalism is ontologically reductionist: there are no events that are not “token-identical” with some physical event or other (Note: See above, sec. 3.3). However, there are no identities between higher-level and lower- level types of events; consequently some events described by the special sciences have no physical explanation at all. -/- All of these reductionist positions are to be contrasted with compositional (milder than mild) physicalism, which asserts that some higher-level events are not even token-identical with physical events because the higher-level event (say, a crash in the stock market) is constituted by innumerable physical particulars in all sorts of states and interactions. -/- Meyering then surveys some of the existing arguments for the nonreducibility of the special sciences. One of the most important is the argument from multiple realizability. The claim is that economics, for example, is not reducible to physics because economic concepts (for example, monetary exchange) are “wildly multiply realizable” (for example, using coins, strings of wampum, signing a check). Thus, there can be no bridge laws and no reduction. Such an argument, however, only cuts against radical physicalism, not the weaker (and a priori more plausible) ideal physicalism. -/- A stronger argument for the indispensability of special-science explanations is based on the role of functional explanations. For example, the functional description of aspirin as an analgesic is in some instances a more useful explanation of its causal role (relieving a headache) than is its description as the chemical level. -/- Meyering’s own contribution focuses neither on multiple realizability of supervenient properties nor on multiple “fillers” of functional roles, but on “multiple supervenience.” In particular, a single subvenient state of affairs (for example, a cloud of free electrons permeating the metal of which a ladder is constructed) may realize a variety of supervenient dispositional properties (in this case, electrical conductivity, thermal conductivity, opacity). An explanation (say, of the cause of a deadly accident) requires reference to the dispositional property (electrical conductivity), not merely to the subvenient property. Meyering argues that it is this possibility of multiple supervenience, not multiple realizability, that gives arguments against reduction based on functional properties their real force. Downward causation, then, can be understood in terms of selective activation of one of several dispositional properties of a lower-level state, and thus can be assigned a stable place in our picture of how the world is organized without upsetting our conception of physics as constituting a closed and complete system of physical events.

In this paper I shall carefully examine some recent arguments for dualism. These arguments presuppose a strong version of physicalism that I consider inappropriate. I shall try to show that, if we reformulate the thesis of physicalism according to Kim's view of physicalism (in terms of the supervenience relation), there is a third option, a version of type physicalism, where physicalism and quaiia could be conciliated. In order to sketch this option, I shall consider the main argument against type (...) physicalism: the explanatory gap argument, and two arguments that Kim mentions against physicalism: the inverted spectrum / zombies argument and the intrinsicality argument. I shall try to show that these three arguments depend upon a misconception of the nature of our ordinary mental concepts. (shrink)

In his (1977) "Anomalous Monism and Kripke's Cartesian Intuitions," Colin McGinn argues that Donald Davidson's anomalous monism is untouched by Kripke's (1980) argument against the identity theory. The type-identity of the physical with the mental may very well fall at the feet of Kripke's powerful arguments, but a token identification, argues McGinn, is left standing due to the simple fact that token physicalism countenances a kind of imagined separation of token mental states with their corresponding token physical states. If McGinn (...) is correct, a full-blooded physicalism is consistent with Kripke's Cartesian intuitions regarding the non-identity of the mental and the physical. But I think McGinn is mistaken. In particular, McGinn misunderstands the nature of an "epistemic counterpart" of a token pain. So contrary to McGinn, token physicalism does not seem to be able to defend against Kripke after all.

A well-known ``overdetermination''argument aims to show that the possibility of mental causes of physical events in a causally closed physical world and the possibility of causally relevant mental properties are both problematic. In the first part of this paper, I extend an identity reply that has been given to the first problem to a property-instance account of causal relata. In the second, I argue that mental types are composed of physical types and, as a consequence, both mental and physical types (...) may be causally relevant with respect to the same physical effect, contrary to the overdetermination argument. In further sections, I argue that mental types have causal powers, consider some objections and reject an alternative version of part-whole physicalism. Throughout I assume that causal relata are tropes and property types are classes of tropes. (shrink)

Mental causation has been a hotly disputed topic in recent years, with reductive and non-reductive physicalists vying with each other and with dualists over how to accommodate, or else to challenge, two widely accepted metaphysical principles—the principle of the causal closure of the physical domain and the principle of causal non-overdetermination—which together appear to support reductive physicalism, despite the latter’s lack of intuitive appeal. Current debate about these matters appears to have reached something of an impasse, prompting the question of (...) why this should be so. One possibility well worth exploring is that, while this debate makes extensive use of ontological vocabulary—by talking, for instance, of substances, events, states, properties, powers, and relations—relatively little attempt has been made within the debate itself to achieve either clarity or agreement about what, precisely, such terms should be taken to mean. Hence, the debate has become somewhat detached from broader developments in metaphysics and ontology, which have lately been proceeding apace, providing us with an increasingly rich and refined set of ontological categories upon which to draw, as well as a much deeper understanding of how they are related to one another. In preparing this volume, the editors invited leading metaphysicians and philosophers of mind to reflect afresh upon the problem of mental causation in the light of some of these recent developments, with a view to making new headway with one of the most challenging and seemingly intractable issues in contemporary philosophy.

Drawing on material from Husserlian phenomenology, we can reconstruct a realist version of anomalous monism (rAM). According to such a view, mental events are identical to some physical events because they simultaneously exemplify mental and physical properties. rAM would have to confront the charge of epiphenomenalism because Husserl rejects psychophysical causal interaction. And as a form of nonreductive physicalism, rAM also faces the challenge of Kim’s supervenience argument and explanatory exclusion. Utilizing Husserl’s conception of mental motivation and contemporary elaborations (...) of substance causation, rAM can refute the accusation of epiphenomenalism and overcome the problem of exclusion.

Most physicalists believe that physicalism is a thesis that denies the existence of fundamental mentality either as a substance or as a property. Therefore, since most physicalists also endorse a posteriori physicalism, according to them, if the future physical theory posits fundamental mentality as a fundamental physical concept, then physicalism will be falsified. In contrast, there are those who believe that the core idea of physicalism is an ontological deference to science (especially physics); the idea that is usually called scientism (...) and is closely related to methodological naturalism. According to them, if physicists posit fundamental mentality as an integral part of the future fundamental physical theory, physicalism will not be falsified, and physicalists may (or should) accept fundamental mentality as a genuine physical concept. In this paper, I argue that there is some historical evidence in support of the latter understanding of physicalism. First, I give some historical evidence that seems to suggest that the historical origin of physicalism is the failure of those explanations – or pseudo-explanations – that have appealed to supernatural non-physical entities. Second, I show that in some of the initial reflections on materialism – the predecessor of physicalism – in the first half of the twentieth century, philosophers understood materialism in terms of the very historical origin.

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)

Flat Physicalism is a theory of through and through type reductive physicalism, understood in light of recent results in the conceptual foundations of physics. In Flat Physicalism, as in physics, so-called "high level" concepts and laws are nothing but partial descriptions of the complete states of affairs of the universe. "Flat physicalism" generalizes this idea, to form a reductive picture in which there is no room for levels, neither explanatory nor ontological. The paper explains how phenomena that seem to be (...) cases of multiple realization of special sciences kinds by physical kinds are fully explains in a reductive physicalist way. Finally, the paper exemplifies the fruitfulness of this reductive approach by showing how it can account even for a case of high-level anomaly in a deterministic universe (for example anomaly of the mental, should this turn our to be a fact about the world) - a result that may be called Anomalous Physicalism.

A Physicalist Manifesto is a full treatment of the comprehensive physicalist view that, in some important sense, everything is physical. Andrew Melnyk argues that the view is best formulated by appeal to a carefully worked-out notion of realization, rather than supervenience; that, so formulated, physicalism must be importantly reductionist; that it need not repudiate causal and explanatory claims framed in non-physical language; and that it has the a posteriori epistemic status of a broad-scope scientific hypothesis. Two (...) concluding chapters argue in detail that contemporary science provides no significant empirical evidence against physicalism and some considerable evidence for it. Written in a brisk, candid and exceptionally clear style, this 2003 book should appeal to professionals and students in philosophy of mind, metaphysics and philosophy of science. (shrink)

This paper challenges the viability of argument from supervenience in defense of a physicalist position on the place of qualia, the subjective properties of consciousness, in a physical or material world. Physicalism, being an ontological thesis that asserts that the only things that really exist are either physical entities or properties, affirms that every mental attribute must be a physical attribute. However, the existence of a quale as an attribute of a mental state falsifies this affirmation. The physicalist (...) argues that qualia supervene on the physical properties in the human body, and that any problem about qualia is, just like any other scientific problem, resolvable scientifically, either in principle or in practice. This paper argues that supervenience is merely a report of the nature of reality, and not a justificatory ontological affirmation that qualia supervene on physical properties. The paper begins with a short description of physicalism and an account of qualia as distinctive character of consciousness. It further articulates and examines the physicalists’ use of the argument from supervenience to establish that qualia supervene on the physical elements in the world. The concluding part shows the errors in the argument from supervenience, and its implication for the truth of physicalism. (shrink)

As a first pass, physicalism is the doctrine that there is nothing over and above the physical. Much recent philosophical work has been devoted to spelling out what this means in more rigorous terms and to assessing the case for the view. What follows is a survey of such work. I begin by looking at competing accounts of what is meant by nothing over and above and then turn to how the physical should be understood. Once we are clear (...) on the options for formulating the physicalist thesis, we will look at the leading argument for the view. Along the way, I will suggest avenues for further exploration.
