Physicalism about the Mind

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.

Property dualism [PD], when adopted by physicalists, is the view that mental properties are irreducible and joined to the physical. Many property dualists who subscribe to physicalism hold epiphenomenalism—the view that the mind does not have a causal role in affecting physical events (e.g., bodily movements).1 In this paper, I examine two possible origins of mental properties and the entailments of those origins if one is committed to physicalism. First, mental properties have a generative origin (e.g., emergence, neurophysiological, etc.). Second, (...) mental properties are fundamental. If mental properties have generative origins, then physicalism has an epistemological problem. Namely, if physical facts determine all mental facts, then we have exceedingly little evidence to favor the widespread existence of epiphenomenal minds over philosophers’ zombies.2 Briefly, the self has mental properties, but the irreducibility of mental properties and their causal inefficacy means that we cannot know the mental status of others. Whereas to claim mental properties as fundamental could entail panpsychism (or proto-panpsychism) and no physicalist method to determine what possesses mental properties. Fundamental mental properties entail the possibility of widespread epiphenomenal minds and the possession of mental properties by unexpected entities so that all biological material and some inanimate objects may have a near equal claim to possessing mental properties.

Best known for his groundbreaking and influential work in Buddhist philosophy, Mark Siderits is the pioneer of “fusion” or “confluence philosophy", a boldly systematic approach to doing philosophy premised on the idea that rational reconstruction of positions in one tradition in light of another can sometimes help address perennial problems and often lead to new and valuable insights. -/- Exemplifying the many virtues of the confluence approach, this collection of essays covers all core areas of Buddhist philosophy, as well as (...) topics and disputes in contemporary Western philosophy relevant to its study. They consider in particular the ways in which questions concerning personal identity figure in debates about agency, cognition, causality, ontological foundations, foundational truths, and moral cultivation. Most of these essays engage Siderits’ work directly, building on his pathbreaking ideas and interpretations. Many deal with issues that have become a common staple in philosophical engagements with traditions outside the West. Their variety and breadth bear testimony to the legacy of Siderits’ impact in shaping the contemporary conversation in Buddhist philosophy and its reverberations in mainstream philosophy, giving readers a clear sense of the remarkable scope of his work.

I analyse Kripke’s modal argument against the mind-brain identity theories. Specifically, he argues against the identity between pain and C-fibres simulation by pointing out the difference between this identity claim and the theoretical identifications, such as ‘Water is H2O’ and ‘Lightning is a motion of electric charges’. Kripke’s argument relies on the assumption that the experience of pains is a simple and homogenous phenomenon, but scientific research shows that it is in fact a quite complex one. We can distinguish at (...) least three components: sensory-discriminative, motivational-affective and cognitive. This discovery makes it possible to reject Kripke’s argument, but it also uncovers a major flaw that is common to all modal arguments against physicalism. They proclaim to answer the fundamental question about the nature of our world by relying on our powers of imagination and without having the relevant factual knowledge. (shrink)

According to conceptual reductive accounts, if properties of one domain can be conceptually reduced to properties of another domain, then the former properties are ontologically reduced to the latter properties. I will argue that conceptual reductive accounts face problems: either they do not recognise that many higher-level properties are correlated with multiple physical properties, or they do not clarify how we can discover new truthmakers of sentences about a higher-level property. Still, there is another way to motivate ontological reduction, the (...) truthmaker reductive explanations (TRE). TRE can be given by using resources from John Heil’s truthmaker theory and the a priori entailment view or the a posteriori entailment view. I will argue that we can give these truthmaker reductive explanations if there are various less-than-perfectly similar physical properties that can be the truthmakers of sentences about higher-level properties and the physical similarity between them can explain why an irreducible higher-level property is not needed.

One of the topics in the philosophy of mind is the discussion of "I", which philosophers have referred to in various interpretations as "The self", "personal identity", "ego", "soul" and "spirit". Philosophers' different theories about the existence and even the nature of this seemingly simple and obvious have turned it into a philosophical problem. Galen Strawson is a physicalist who has addressed this issue by interpreting “The self”. On the one hand, he believes in the existence of the "empirical self", (...) but on the other hand, he denies such qualities as Long-term persistence, personality, and agency, which seem to be essential to the meaning of the "I". The present paper tries to address, by an analythical-critical method, the question of how Strawson believed in the existence of the "I" despite the non-acceptance of these three characteristics. In this regard, first Strawson's view on the nature and existence of the "I" is analyzed, and after evaluating his view, it is concluded that the elimination of these three characteristics is due to weaknesses such as adopting a physicalist basis, a phenomenological method, and a purely mental view of the "I", confusion of the two positions of Truth and proof and his weakness in explaining the nature of unity over time.

This book demonstrates how a radical version of physicalism (‘No-Self Physicalism’) can offer an internally coherent and comprehensive philosophical worldview. It first argues that a coherent physicalist should explicitly treat a cognitive subject merely as a physical thing and should not vaguely assume an amorphous or even soul-like subject or self. This approach forces the physicalist to re-examine traditional core philosophical notions such as truth, analyticity, modality, apriority because our traditional understandings of them appear to be predicated on a cognitive (...) subject that is not literally just a physical thing. In turn, working on the assumption that a cognitive subject is itself completely physical, namely a neural network-based robot programmed by evolution (hence the term ‘No-Self’), the book proposes physicalistic theories on conceptual representation, truth, analyticity, modality, the nature of mathematics, epistemic justification, knowledge, apriority and intuition, as well as a physicalistic ontology. These are meant to show that this No-Self Physicalism, perhaps the most minimalistic and radical version of physicalism proposed to date, can accommodate many aspects that have traditionally interested philosophers. Given its refreshingly radical approach and painstakingly developed content, the book is of interest to anyone who is seeking a coherent philosophical worldview in this age of science. (shrink)

This chapter presents the following hypothesis: There is a perfectly sensible conception of the mind, consciousness, the self, what we mean by ‘I,’ how we perceive and know, and how we remember and decide, all of which cohere amongst one another as well as with what we know about the brain, according to which it is possible for one person to experience directly the conscious states of another person. Not only can one person be directly aware of the conscious states (...) of another person, he can be more aware of them than their original owner. He can even be aware of them when their original owner will never be aware of them. Mindmelding is possible, and this possibility removes much of the force from the mind-body problem by removing the impasse caused by the belief in privacy. It removes what some philosophers saw as a need to posit strange metaphysical categories. The subject's sense of self can be separated from the object of her conscious awareness which can be bound to another's sense of self. (shrink)

This paper describes a version of type identity physicalism, which we call Flat Physicalism, and shows how it meets several objections often raised against identity theories. This identity theory is informed by recent results in the conceptual foundations of physics, and in particular clar- ifies the notion of ‘physical kinds’ in light of a conceptual analysis of the paradigmatic case of reducing thermody- namics to statistical mechanics. We show how Flat Physi- calism is compatible with the appearance of multiple realisation (...) in the special sciences, and how and in what sense the special sciences laws are autonomous from the laws of physics, despite the full reductive picture of Flat Physicalism. We compare our view with a recent proposal by William Bechtel that accounts for the appearance of levels in mechanistic explanations. (shrink)

Thought experiments, one of the most effective ways of acquiring knowledge, are an intellectual tool frequently used by scientists or thinkers in their fields of study. Thought experiments used to respond to scientific issues are considered scientific thought experiments, while thought experiments used for philosophical problems are called philosophical thought experiments. In this context, firstly, the differences between scientific and philosophical thought experiments are determined in the article. In particular, philosophical thought experiments are often needed in discussions within the field (...) of epistemology. For this reason, in the rest of the study, the knowledge argument put forward against the idea of physicalism, which is one of the important views in epistemology and which claims that the natural world is basically physical and that everything can be explained by physical laws is included. The knowledge argument briefly argues that there are non-physical properties and information that can only be discovered through conscious experience. Accordingly, it is argued that someone who has all physical knowledge about another conscious may lack knowledge of what it would feel like to have subjective experiences of that entity such as qualia. Consequently, the main idea of the article is to reveal how an epistemological thesis has been questioned by various philosophers in the context of philosophical thought experiments such as Mary’s room, ‘What is it like to be a Bat’, The Martian and the Philosophical Zombie. - Bilgi edinmenin en etkili yollarından bir tanesi olarak değerlendirilen düşünce deneyleri bilim insanları ya da düşünürler tarafından kendi çalışma alanları içerisinde sıklıkla başvurulan düşünsel bir araçtır. Bilimsel konulara cevap vermek amacıyla gerçekleştirilen düşünce deneyleri bilimsel düşünce deneyleri olarak değerlendirilirken, felsefi sorunlara yönelik kullanılan düşünce deneyleri ise felsefi düşünce deneyleri olarak adlandırılmaktadır. Bu kapsamda makalede ilk olarak bilimsel ve felsefi düşünce deneyleri arasındaki farklılıklar belirlenmektedir. Özellikle, epistemoloji alanı içerisinde yer alan tartışmalarda felsefi düşünce deneylerine sıklıkla ihtiyaç duyulmaktadır. Bu nedenle çalışmanın devamında epistemolojide önemli görüşlerden bir tanesi olan ve doğal dünyanın en temelde fiziksel olduğu ve fiziksel yasalarla her şeyin açıklanabileceği iddiasında bulunan fizikalizm düşüncesine karşı ileri sürülmüş bilgi argümanına yer verilmektedir. Bilgi argümanı kısaca sadece bilinçli deneyim yoluyla elde edilebilen ve fiziksel olarak ifade edilemeyen öznel deneyimlerin ve özelliklerin olduğunu savunmaktadır. Buna göre, başka bir bilinçli varlık hakkında bütün fiziksel bilgiye sahip olan birinin, o varlığın qualia gibi öznel deneyimlerine sahip olmasının nasıl bir his olduğu konusundaki bilgilerden yoksun olabileceği fikri savunulmaktadır. Bu doğrultuda, makalenin temel savı fizikalizm gibi epistemolojik bir teze Mary’nin Odası, ‘Yarasa Olmak Nasıl Bir Şeydir’, Marslı ve Felsefi Zombi gibi felsefi düşünce deneyleri bağlamında çeşitli filozoflarca nasıl itiraz edildiğini ve düşünce deneylerinin bu bağlamda nasıl kullanıldığını ortaya koymaktır.

Dans cet article, je propose de défendre le monisme russellien, une théorie posant l’existence de quiddités phénoménologiques au fondement de la réalité. Je propose en particulier de montrer que le monisme russellien échappe aux objections qui en font une version inadéquate du physicalisme. Pour ce faire, j’identifie les trois raisons qui motivent le physicalisme, c’est-à-dire la parcimonie, le naturalisme et l’argument de la clôture causale, et j’argumente qu’il faut considérer que le monisme russellien satisfait ces trois motivations. Ainsi, si j’ai (...) raison, le monisme russellien devrait être considéré comme imperméable aux critiques qui voient en lui une forme problématique de physicalisme. (shrink)

Physicalism is the idea that everything either is physical or is nothing over and above the physical. For this formulation of physicalism to have determinate content, it should be identified what the “physical” refers to; i.e. the body problem. Some other closely related theses, especially the ones employed in the causal arguments for different versions of physicalism, and more especially the causal closure thesis, are also subject to the body problem. In this paper, I do two things. First, I explore (...) the structure of causal arguments for physicalism that represents a general argument. To do this, the premises and the conclusion of the general argument are given exact formulations. Second, drawing on those premises, especially the causal closure thesis, I propose a naturalistic formulation of the physical that satisfies the requirements any formulation of the physical is expected to fulfill. Following this proposal, we also have a recursive algorithm to recognize the set of all physical events. (shrink)

We present a new thought experiment that raises a threat for Minimal Physicalism, i.e. the thesis according to which mental properties supervene on physical properties. Our proposal is an example of the so called hard problems in philosophy of mind, in particular the problem of maximal consciousness. We do not however presuppose anything about its very nature apart from the minimal, weak assumption that it is determined by first order mental properties. We argue that either Minimal Physicalism is unable to (...) give an adequate account of the new thought experiment we present or has to explain the fact that two numerically distinct but physically indistinguishable individuals have different maximal consciousness due to their spatial location. We contend that this last conclusion is strongly at variance with our contemporary scientific image of the world. (shrink)

Physicalism is often characterized as an empirical hypothesis. But according to an alternative conceptualization, it is instead a stance or an attitude. I analyze Roy Wood Sellars’s materialist philosophy in order to show that it is a counterexample to a specific physicalist empirical hypothesis: the minimal completeness of the physical. However, it is arguably not reducible to a stance: it is a meaningful metaphysical thesis with substantive cognitive content.

Physicalism demands an explication of what it means for something to be physical. But the most popular way of providing one—viz., characterizing the physical in terms of the postulates of a scientifically derived physical theory—is met with serious trouble. Proponents of physicalism can either appeal to current physical theory or to some future physical theory (preferably an ideal and complete one). Neither option is promising: currentism almost assuredly renders physicalism false and futurism appears to render it indeterminate or trivial. The (...) purpose of this essay is to argue that attempts to characterize the mental encounter a similar dilemma: currentism with respect to the mental is likely to be inadequate or contain falsehoods and futurism leaves too many significant questions about the nature of mentality unanswered. This new dilemma, we show, threatens both sides of the current debate surrounding the metaphysical status of the mind. (shrink)

It is widely accepted that supervenience is a minimal commitment of physicalism. In this article, however, I aim to argue that physicalism should be exempted from the supervenience requirement. My arguments rely on a parallel between ontological dependence and causal dependence. Since causal dependence does not require causal determination, ontological dependence should not require ontological determination either. Moreover, my approach has a significant theoretical advantage: if physicalism is not committed to supervenience, then the metaphysical possibility of zombies—which is still wide (...) open after all these years—would pose no challenge to physicalism.

Morris’s book is a valuable contribution. For the reasons below, I don’t think his case against NRP succeeds, and his version of EP faces a serious difficulty. Even so, this is an admirably clear, subtle, and well-informed brief, and philosophers interested in the structure of natural reality have much to gain from Morris’s insightful discussion and argumentation.

Both the special sciences and ordinary experience suggest that there are metaphysically emergent entities and features: macroscopic goings-on (including mountains, trees, humans, and sculptures, and their characteristic properties) which depend on, yet are distinct from and distinctively efficacious with respect to, lower-level physical configurations and features. These appearances give rise to two key questions. First, what is metaphysical emergence, more precisely? Second, is there any metaphysical emergence, in principle and moreover in fact? Metaphysical Emergence provides clear and systematic answers to (...) these questions. Wilson argues that there are two, and only two, forms of metaphysical emergence of the sort seemingly at issue in the target cases: 'Weak' emergence, whereby a dependent feature has a proper subset of the powers of the feature upon it depends, and 'Strong' emergence, whereby a dependent feature has a power not had by the feature upon which it depends. Weak emergence unifies and illuminates seemingly diverse accounts of non-reductive physicalism; Strong emergence does the same as regards seemingly diverse anti-physicalist views positing fundamental novelty at higher levels of compositional complexity. After defending the in-principle viability of each form of emergence, Wilson considers whether complex systems, ordinary objects, consciousness, and free will are actually metaphysically emergent. She argues that Weak emergence is quite common, and that there is Strong emergence in the important case of free will. (shrink)

There is a standard way of interpreting physicalism. This is as a completeness thesis of some kind. Completeness physicalists believe there is or in principle could be some future physics that provides a complete explanatory or ontological basis for our universe. And this provides a sense in which physics is special among the sciences, the sense in which it is fundamental. This paper contrasts this standard completeness physicalism with what is a more plausible maximality physicalism. Maximality physicalists believe physics is (...) special only in its providing an epistemic framework that is ontologically or explanatorily superior in some respect. This paper shows how completeness physicalists cannot, while maximality physicalists can, provide an adequate explanation of the empirical support for and the pragmatic usefulness of physicalism. It also shows how maximality physicalism is better supported in light of several developments from late twentieth century philosophy of science. (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.

Some philosophers consider that some of their colleagues deny that consciousness exists. We shall call the latter ‘deniers’, adopting a term that was initially meant pejoratively. What do the deniers deny? In order to answer this question, we shall examine arguments, both of some deniers and of their critics, and present denialism as a systematic highly non-trivial position that has had some interesting achievements. We will show that the denialist project concerns the epistemology of the mind and specifically of consciousness: (...) what can be known about it, and how it can be known. The main argument of denialism is that first-person reports about the mental realm are not always the best source of information about that realm, and are certainly not reliable. This leads the deniers to realize that the reference and meaning of mental terms as used in standard philosophical literature are vague and call for clarification, and that what many take to be empirical data in the study of the mind are actually heavily laden with theory. Denialism thus makes scientific and philosophical research clearer and more fruitful. (shrink)

Russellian monism – an influential doctrine proposed by Russell (1927/1992) – is roughly the view that the natural sciences can only ever tell us about the causal, dispositional, and structural properties of physical entities and not about their categorical properties, and, moreover, that our qualia are constituted by categorical properties. Recently, Stoljar (2001a, 2001b), Strawson (2008), Montero (2010, 2015), Alter and Nagasawa (2012), and Chalmers (2015) have attempted to develop this doctrine into a version of physicalism. Russellian monism faces the (...) so-called combination problem, according to which it is difficult to see how categorical properties could collectively constitute qualia. In this paper, I suggest that there is an insufficiently discussed aspect of the combination problem which I call the difference-maker problem. Taking the difference-maker problem into account, I argue that the combination problem – whether or not it can be solved – results in a dilemma for the project of developing Russellian physicalism. That is, Russellian monism is either physicalistically unacceptable or it is implausible; hence, Russellian monism and physicalism are incompatible. (shrink)

Conceivability arguments constitute a serious threat against reductive physicalism. Recently, a number of authors have proven and characterized a devastating logical truth, centered on these arguments: namely, that their soundness entails the inconceivability of reductive physicalism. In this paper, I demonstrate that is only a logical truth when reductive physicalism is interpreted in its stronger, intrinsic sense, as opposed to its weaker—yet considerably more popular—extrinsic sense. The basic idea generalizes: perhaps surprisingly, stronger forms of reduction are uniquely resistant to the (...) conceivability arguments opposing them. So far as the modal epistemology of reduction is concerned, therefore, it pays to go intrinsic. (shrink)

Materialists about human persons think that we are material through and through—wholly material beings. Those who endorse materialism more widely think that everything is material through and through. But what is it to be wholly material? In this article, I answer that question. I identify and defend a definition or analysis of ‘wholly material’.

I argue for three claims. First, there is a strong argument for identity physicalism (Lewis, Sider, Dorr) over dualism. It does achieve the physicalist dream of a maximally simple and uniform view of reality. However, there are also strong arguments against identity physicalism concerning the special nature of conscious experiences. Second, although nonidentity "ground" physicalism (Campbell, Johnston, Schaffer) is a possible fallback position, there is no reason to prefer to property dualism. It provides an equally complex and unattractive picture of (...) nature. Third, assuming identity physicalism fails, we also should not much care about which of these options is right. In fact, it becomes difficult to understand the difference. The upshot is that, when it comes to the metaphysics of consciousness, the “big divide” is between identity physicalism (Lewis, Sider, Dorr) and all the rest. This is where the debate should focus. (shrink)

This chapter considers potential applications of grounding to the formulation of physicalism. I begin with an overview of competing conceptions of the physical and of physicalism. I then consider whether grounding physicalism overcomes well-known and seemingly fatal problems with supervenience physicalism. I conclude that while grounding physicalism improves upon supervenience physicalism in certain respects, it arguably falls victim to some of the same difficulties.

The disciplinary characterisation (DC) is the most popular approach to defining metaphysical naturalism and physicalism. It defines metaphysical naturalism with reference to scientific theories and defines physicalism with reference to physical theories, and suggests that every entity that exists is a posited entity of these theories. DC has been criticised for its inability to solve Hempel’s dilemma and a list of problems alike. In this paper, I propose and defend a novel version of DC that can be called a historical (...) paths approach. The idea is (roughly) that metaphysical naturalism can be defined with reference to the historical ideas that current scientific ideas descend from. I argue that it is not rendered implausible by the above problems, and hence that DC is more defensible and attractive than it may first appear. I then argue that the approach also provides a useful framework for the naturalisation of the philosophy of mind and phenomenology. (shrink)

ABSTRACT This essay has three goals. The first is to introduce the notion of fundamentality and to argue that physicalism can usefully be conceived of as a thesis about fundamentality. The second is to argue for the advantages of fundamentality physicalism over modal formulations and that fundamentality physicalism is what many who endorse modal formulations of physicalism had in mind all along. Third, I describe what I take to be the main obstacle for a fundamentality-oriented formulation of physicalism: ‘the problem (...) of abstracta’, which asks how physical can accommodate phenomena such as mathematics and universals, and which modal formulations do not face. I canvas three solutions: the inapt for ground solution, the concrete restriction, and the contingency restriction. (shrink)

In this paper, I argue that absences pose a challenge to our understanding of physicalism that has not been properly appreciated. I do this by setting out a thought experiment involving a being in whom absence properties occupy the causal roles that functionalists take to define mental properties, in which case these absence properties realize the being’s mental properties. Such a being should be compatible with the truth of physicalism, I argue, even though its mental properties are neither themselves physical (...) properties nor are they realized/grounded in physical properties—instead, they are realized/grounded in (nonphysical) absence properties. I argue that the case serves as a counterexample to leading formulations of physicalism that appeal to realization or grounding, but not to standard supervenience-based formulations of physicalism, because the latter typically include negative truths in their supervenience base in addition to physical truths. I show how realization- and grounding-based formulations of physicalism might be revised to handle the problem, but also recommend that we rethink how we understand physicalism and the role that negative entities can play for physicalists.

Nonreductive physicalists endorse the principle of mental causation, according to which some events have mental causes: Sid climbs the hill because he wants to. Nonreductive physicalists also endorse the principle of physical causal completeness, according to which physical events have sufficient physical causes: Sid climbs the hill because a complex neural process in his brain triggered his climbing. Critics typically level the causal exclusion problem against this nonreductive physicalist model, according to which the physical cause is a sufficient cause of (...) the behavioural effect, so the mental cause is excluded from causally influencing Sid’s behaviour. In this paper I demonstrate how numerous nonreductive physicalists have responded to the causal exclusion problem by weakening the principle of physical causal completeness in numerous ways. The result: either numerous nonreductive physicalist solutions fail on account of the fact that they do not satisfy a robustly defined principle of physical causal completeness, or there is an accelerating trend of solving the causal exclusion problem by suitably weakening the principle of physical causal completeness.

Many hold that (1) consciousness poses a uniquely hard problem. Why is this so? Chalmers considers 12 main answers in 'The Meta-Problem of Consciousness'. This paper focuses on number 11, and is principally addressed to those who endorse (1) because they think that (2) consciousness can't possibly be physical. It argues that to hold (2) is to make the mistake of underestimating the physical, and that almost all who make this mistake do so because they think they know more about (...) the physical than they do. When we see things right, we see that there is nothing in physics nor in our everyday experience of the physical that gives us any good reason to hold (2). This leaves us free to embrace the overwhelmingly strong reasons for accepting that (3) consciousness is wholly physical. The correct general response is the same as the response to wave-particle duality: acceptance without expectation of understanding. (shrink)

O Fisicalismo tem sido a posição filosófica monista mais aceita no mainstream do debate contemporâneo sobre a natureza do mental. Mas o que significa dizer que tudo o que existe é “físico”? O presente trabalho busca responder à pergunta: Como as teses fisicalistas contemporâneas têm definido o termo ‘físico’ em suas proposições? Para respondê-la foi realizada uma investigação teórico-filosófica baseada em revisão bibliográfica e análise lógica e conceitual. Quatro categorias gerais de definição do termo ‘físico’ foram identificadas numa revisão da (...) literatura. Existem igualmente fortes críticas às propostas de definição em toda a discussão filosófica. Não temos uma definição incontroversa do que seja uma propriedade física, tampouco consenso sobre qual deveria ser a formulação mais adequada da tese fisicalista. Assim, a questão que se coloca é: Por que estamos discutindo o valor de verdade de uma tese que nem mesmo tem conseguido ser formulada de forma adequada? (shrink)

I argue physicalism should be characterized as the thesis that all behavior is law-governed. This characterization captures crucial desiderata for a formulation of physicalism, including its broad import and worldview defining features. It also has more local virtues, such as avoiding Hempel’s dilemma. A particularly important implication, I argue, is that this thesis makes the question of the mind’s physicality turn on what the mind can do- rather than what experience is like.

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)

I present three problems regarding the Problem of the Base. They concern the nature of information, the kind of Platonism that physicalists allegedly confront, and the constraints imposed by causal principles. These problems focus on the notion of information and its relation to the Problem of the Base. I also highlight the importance of Schneider's paper, particularly its relevance for future debates.

Standard physicalism is repudiated by Susan Schneider on the grounds that the science of physics at physicalism's foundation is individuated by mathematics, revealing that science is abstract rather than concrete. She seeks to remedy the situation for physics, though not for physicalism, with a panprotopsychist variant of panpyschism. Her approach is clever and well-developed, but I believe it suffers from at least two flaws. First, with few exceptions individuation is the wrong tool for the discovery of a thing's nature; second, (...) panpsychism and its proto variant have problems no less worrisome than those attributed to standard physicalism. Moreover, once developed it is questionable whether a surviving panpsychism is distinct from a less troubled emergentism. (shrink)

Susan Schneider argues that the entities to be identified as part of the 'physical base' for physicalism must be in part abstract and that this fact either falsifies physicalism or renders it so problematic as to be 'no physicalism worth having'. I accept the abstractness of the entities but argue both that physicalism is consistent with such and that none of the alleged problems for Platonistic physicalism are serious.

I endorse the central message of Keith Frankish's 'Illusionism as a Theory of Consciousness': if physicalism is true, phenomenal consciousness must be an illusion. Attempts to find an intermediate position between physicalist illusionism and the rejection of physicalism are untenable. Unlike Frankish, however, I reject physicalism, while still endorsing illusionism. My misgivings about physicalist illusionism are that it removes any rational basis from our judgment inclinations concerning consciousness, undermines the epistemic basis required to explain the genesis of our physical conception (...) of the world, and leads to a widespread scepticism about the basis of philosophical reflection. I endorse the core of physicalist intuition, but not its metaphysic, and sketch my alternative illusionism, which resists physicalism's merging of philosophy with science without thereby impinging on science. I conclude that physicalism is fostered by inattention to metaphilosophy and threatens philosophy's distinctive voice; but that illusionism itself is an important insight. (shrink)

This correction reflects that I forgot to cite Stephan Leuenberger's unpublished work in the paragraph beginning "More promising, perhaps, is the orthodox view ..." in Section 5. The overall argument of Section 5 is a development of an argument I gave in footnote 27 of 'No Work for a Theory of Grounding' (Inquiry, 2014). At issue in the relevant sections of 'No Work...' and 'Grounding-based Formulations...' is whether a proponent of Grounding has resources to accommodate strongly emergent phenomena, where strong (...) emergence is understood as contrasting with physicalism. In 'No Work...', after arguing in the text that an account of strong emergence as involving a failure of full Grounding would not accommodate the live possibility that strongly emergent goings-on might be partially but not completely metaphysically dependent on physical goings on, I considered in note 27 whether strong emergence, again understood as contrasting with physicalism, could be characterized by appeal to a Finean notion of partial Grounding, as the view that strongly emergent goings-on are partially but not fully Grounded in physical goings-on, and I argued that assuming that the notion of partial Grounding was taken to be primitive, then (since there were no prospects of defining full Grounding in terms of primitive partial Grounding along lines of defining a general notion of parthood in terms of primitive proper parthood or identity), such an approach would require that full Grounding also be taken as primitive, with possibly yet another primitive connecting partial and full Grounding. -/- I heard Leuenberger's talk 'Emergence and Failures of Supplementation' in May 2015; for purposes of developing my previous argument (as per Section 5 in 'Grounding-based Formulations...') this talk was helpful since Leuenberger correctly argued that there were also no prospects for implementing the partial Grounding-based strategy by taking full Grounding to be primitive and defining partial Grounding in terms of full Grounding, since that would import a weak supplementation structure that might not be present in cases of strong emergence. I wrote to Leuenberger asking for his slides so that I could reference him and his work (which again is presented in the paragraph beginning "More promising, perhaps, is the orthodox view..."), but somehow forgot to include a citation to his talk, for which I sincerely apologize. -/- One last thing: the erratum is a bit misleading about my use of Leuenberger's work. My discussion of whether a primitivist (i.e., 'non-orthodox') understanding of Finean partial Ground serves as a suitable basis for a partial Grounding-based approach to strong emergence stems from footnote 27 of my 2014, not Leuenberger's 2015 talk, and in both 'No Work...' and 'Grounding-based Formulations...' I argue that such an approach would be problematic, not "suitable", since involving two or three primitives. Also worth noting is that I do not claim or argue that the orthodox conception of partial Grounding as defined in supplementary fashion in terms of full Grounding is *incompatible* with strong emergence. Again, at issue in both 'No Work...' and in 'Grounding-based Formulations...' is strong emergence understood as contrasting with physicalism, so the relevant application of a partial Grounding-based strategy, whether or not involving an 'orthodox' account of partial Grounding as definable in terms of full Grounding, is in my papers one according to which strongly emergent goings-on are partially but not fully Grounded in *physical* goings-on. So far as I can tell, there might be cases of strong emergence that *do* obey supplementation, and which would be compatible with a partial Grounding-based account of strong emergence, where the operative notion of partial Grounding is 'orthodox' (non-primitive). For my purposes, what is important is that cases of strong emergence might not obey supplementation. (shrink)

I problematize Grounding-based formulations of physicalism. More specifically, I argue, first, that motivations for adopting a Grounding-based formulation of physicalism are unsound; second, that a Grounding-based formulation lacks illuminating content, and that attempts to imbue Grounding with content by taking it to be a strict partial order are unuseful and problematic ; third, that conceptions of Grounding as constitutively connected to metaphysical explanation conflate metaphysics and epistemology, are ultimately either circular or self-undermining, and controversially assume that physical dependence is incompatible (...) with explanatory gaps; fourth, that in order to appropriately distinguish physicalism from strong emergentism, a Grounding-based formulation must introduce one and likely two primitives in addition to Grounding; and fifth, that understanding physical dependence in terms of Grounding gives rise to ‘spandrel’ questions, including, e.g., “What Grounds Grounding?”, which arise only due to the overly abstract nature of Grounding. (shrink)

Grounding is all the rage in analytical metaphysics. But here I give three reasons for not appealing to a primitive relation of grounding in formulating physicalism. (1) It probably can't do the key job it would need to do. (2) We don't need it, since we already have realization. (3) It is probably not even consistent with physicalism.
