Psychophysical Reduction

What should the Buddhist attitude be to rebirth if one accepts that it is inconsistent with current science? This chapter critically engages forms of Buddhist agnosticism that adopt a position of uncertainty about rebirth but nevertheless recommend ‘behaving as if’ it were true. What does it mean to behave as if rebirth were true, and are Buddhist agnostics justified in adopting this position? This chapter engages this question in dialogue with Mark Siderits’ reductionist analysis of the Buddhist doctrine of the (...) two truths, conventional and ultimate. Richard Hayes (1998) characterises talk of rebirth as a useful fiction. Siderits characterises talk of persons as a useful fiction and explains and justifies statements that involve it as conventionally true despite persons not featuring in our final or ultimate ontology. Does rebirth satisfy the same criteria to count as conventionally true, and does thinking of it in these terms help explain and justify what it might mean to behave as if rebirth were true? This chapter will defend a conditional yes to these questions. In the process, it will clarify what is distinctive about the traditional Buddhist approach to rebirth, provide an analysis of how the concept of rebirth might relate to practical outcomes, and address some limitations of this approach.

This very brief but conceptually dense article provides a useful definition of consciousness, puts self consciousness into proper perspective, clarifies the nature of time, change and inertia, and ties consciousness to the foundations of physics as the inherent and fundamental process in nature. It is an implicit argument for a type of (proto) panpsychism or panexperientialism.

The subset realization view proposes to solve the causal exclusion problem of non‐reductive mental instances by taking the mental instance as a part of its physical realizer. Many philosophers have argued that such a part‐whole relation will undermine physicalist realization because parts are ontologically prior to their wholes and the subset view is thus flawed. I argue that the relation that the subset view should propose is different from the ordinary part‐whole relation. What they should propose is another kind of (...) part‐whole relation under which parts are posterior to wholes. So, the subset view is not flawed in the aforementioned aspect. But discussion of the new part‐whole relation reveals that the subset view is in lack of a crucial argument against the exclusion reasoning, thus cannot solve the exclusion problem. Adopting the principle of causal proportionality (a route subset realizationists sometimes take) will not help the subset view either. So, my conclusion is, the subset view is yet to find a way to solve the exclusion problem. (shrink)

Nonreductive physicalism states that actions have sufficient physical causes and distinct mental causes. Nonreductive physicalism has recently faced the exclusion problem, according to which the single sufficient physical cause excludes the mental causes from causal efficacy. Autonomists respond by stating that while mental-to-physical causation fails, mental-to-mental causation persists. Several recent philosophers establish this autonomy result via similar models of causation :1031–1049, 2016; Zhong, J Philos 111:341–360, 2014). In this paper I argue that both of these autonomist models fail on account (...) of the problem of Edwards’s Dictum. However, I appeal to foundational principles of action theory to resuscitate mental-to-mental causation in a manner that is consistent with the models of causation endorsed by these autonomists.

Drawing on a rich pragmatist tradition, this book offers an account of the different kinds of ‘oughts’, or varieties of normativity, that we are subject to contends that there is no conflict between normativity and the world as science describes it. The authors argue that normative claims aim to evaluate, to urge us to do or not do something, and to tell us how a state of affairs ought to be. These claims articulate forms of action-guidance that are different in (...) kind from descriptive claims, with a wholly distinct practical and expressive character. This account suggests that there are no normative facts, and so nothing that needs any troublesome shoehorning into a scientific account of the world. This work explains that nevertheless, normative claims are constrained by the world, and answerable to reason and argumentation, in a way that makes them truth-apt and objective. (shrink)

A popular solution to the causal exclusion problem in the non-reductive physicalist camp is the trope identity solution. But this solution is haunted by the “quausation problem” which charges that the trope only confers causal powers qua physical, not qua mental. Although proponents of the trope solution have responded to the problem by denying the existence of properties of tropes, I do not find their reply satisfactory. Rather, I believe they have missed the core presupposition behind the quausation problem. I (...) will argue that the presupposition is the generalist notion of causation. Then, for the trope theorists to solve the quausation problem, they need to abandon the generalist notion and adopt the singularist notion of causation. However, making that move will lead them to a new quausation problem, rendering irreducible mental types causally irrelevant and mental causal explanations reducible. Either adopting a generalist notion or a singularist notion of causation, a quausation problem awaits the trope solution. Given this dilemma, my conclusion is that the trope identity solution cannot solve the exclusion problem in a non-reductive way. Moreover, the dilemma can be generalized, showing that token physicalism is a shaky position. (shrink)

Why do we value higher-level scientific explanations if, ultimately, the world is physical? An attractive answer is that physical explanations often cite facts that don’t make a difference to the event in question. I claim that to properly develop this view we need to commit to a type of deterministic chance. And in doing so, we see the theoretical utility of deterministic chance, giving us reason to accept a package of views including deterministic chance.

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.

We show that the so-called Multiple-Computations Theorem in cognitive science and philosophy of mind challenges Landauer’s Principle in physics. Since the orthodox wisdom in statistical physics is that Landauer’s Principle is implied by, or is the mechanical equivalent of, the Second Law of thermodynamics, our argument shows that the Multiple-Computations Theorem challenges the universal validity of the Second Law of thermodynamics itself. We construct two examples of computations carried out by one and the same dynamical process with respect to which (...) Landauer’s principle implies contradictory predictions concerning the entropy increase. Our two examples are based on a weak version of the Multiple-Computations Theorem, which is quite uncontroversial, and therefore they amount to a clear refutation of the universal validity of Landauer’s Principle. We consider some responses to this argument that do not attempt to single out one computation over the others, and we show that they do not work. We further consider ways out of the argument by externalist approaches supporting the computational theory of the mind who propose that the interaction of a computing system with the environment is enough to select a single computation over the others. We show on physical grounds that this approach fails too. We then reverse the direction of our challenge and formulate a dilemma for supporters of the computational theory of the mind: they must reject the causal closure of physic; or else they must accept on a priori grounds that Landauer’s Principle and the Second Law of thermodynamics are not universally valid. Finally, we present our version of a type–type mind-brain identity theory called Flat Physicalism, which is based on the paradigm case of statistical mechanics, and we show that it circumvents the challenge from Landauer’s Principle and the Multiple-Computations Theorem and does not fall prey to our dilemma.

Espousing non-reductive physicalism, how do we pick out the specific relevant physical notion(s) from physical facts, specifically in relation to phenomenal experience? Beginning with a historical review of Gilbert Ryle’s behaviorism and moving through Hilary Putnam’s machine-state functionalism and Wilfrid Sellars’ inferential framework, up to more contemporaneous computationalist- and cognitivist-functionalism (Gualtiero Piccinini), we survey accounts of mentality that countenance the emergence of mental states vide input- and output-scheme. Ultimately arriving at the conclusion that functionalism cannot account for problems such as (...) no-cognition reports, we see any robust defense of physicalism must appeal to other principles. Thus we move on to the question of emergence, not as it pertains to the hard(er) problem, but to the matter of conceptual externalization of mental properties from physical properties. Accordingly, we navigate Karen Bennett’s compatibilist solution to the exclusion argument against mental causation for the non-reductive physicalist position, according to which the physical effects of mental cases are not overdetermined, demonstrating that this backfires by offering a path for the mind-body interactionist Dualist to claim causal closure by appealing to this same schema. We conclude with a series of conceptual musings regarding rationality which take into account our challenges and findings, querying about whether phenomenal consciousness is a fundamentally private, or socially configured, notion.

Remember how Kim Mental causation, Clarendon Press, Oxford, 1993b) used to argue against non-reductive physicalism to the effect that it cannot accommodate the causal efficacy of the mental? The argument was that if physicalists accept the causal closure of the physical, they are faced with an exclusion problem. In the original version of the argument, the dependence holding between the mental and the physical was cashed out in terms of supervenience. Due to the work or Fine and others, we have (...) since come to realize that modal notions are not well-suited to perform the work of properly characterizing dependence. As a consequence of this, an increasingly larger community of contemporary metaphysicians prefer to spell out mental-physical dependence in terms of a non-causal and non-reductive notion called grounding, which is intended to target a particular sort of metaphysical relation that takes us from ontologically less fundamental features of the world to that which is more fundamental. In this paper I join forces with those who think that this shift in focus is on the right track. More specifically, I will argue that the grounding physicalist can solve the exclusion problem in a way that is preferable to the supervenience-based nonreductive physicalist solution, as well as in a way that is compatible with the externalist picture of the mental.

Review of Horgan, Sabatés, and Sosa's (eds.) *Qualia and Mental Causation in a Physical World: Themes from the Philosophy of Jaegwon Kim*.

Some non-reductionists claim that so-called ‘exclusion arguments’ against their position rely on a notion of causal sufficiency that is particularly problematic. I argue that such concerns about the role of causal sufficiency in exclusion arguments are relatively superficial since exclusionists can address them by reformulating exclusion arguments in terms of physical sufficiency. The resulting exclusion arguments still face familiar problems, but these are not related to the choice between causal sufficiency and physical sufficiency. The upshot is that objections to the (...) notion of causal sufficiency can be answered in a straightforward fashion and that such objections therefore do not pose a serious threat to exclusion arguments.

Artikel ini bertujuan untuk memaparkan bagaimana penyebaban sosial dapat terjadi dalam perspektif individualisme non-reduktif (Non-reductive Individualism/NRI) R. Keith Sawyer. NRI adalah perluasan argumen fisikalisme non-reduktif dari filsafat akal budi untuk memberikan bingkai (framework) baru dalam melihat debat ontologis dan metodologis filsafat ilmu sosial. Cara yang digunakan adalah membasiskan landasan ontologis ilmu sosial pada eksistensi individu (individualisme ontologis), sekaligus mengiyakan dua level analisis properti, yakni level individual (bawah) dan sosial (atas) (dualisme properti). Mengingat posisi non-reduktif selalu dibayangi problem overdeterminasi dan epifenomena (...) saat berbicara tentang daya kausal level atas, Sawyer mengkombinasikan argumen supervenien (supervenience), perealisasian berlipat (multiple realizability/mr), disjungsi tak beraturan (wild disjunction/wd), serta kemunculan kolaboratif (collaborative emergence), untuk memperkuat pandangan penyebaban supervenien (supervenient causation/sv) dalam domain sosial.

In C. S. Lewis’s Christian Apologetics: Pro and Con, I took the con in a debate with Victor Reppert about the soundness of Lewis’s famous “argument from reason.” Reppert then extended his argument in an article for Philosophia Christi; this article is my reply. I show that Reppert’s argument fails for three reasons. It “loads the die” by falsely assuming that naturalism, by definition, can't include mental causation "on the basic level.". Physical processes can reliably produce true beliefs. And reasoning (...) isn’t necessarily mental. (shrink)

Kim’s causal exclusion argument purports to demonstrate that the non-reductive physicalist must treat mental properties (and macro-level properties in general) as causally inert. A number of authors have attempted to resist Kim’s conclusion by utilizing the conceptual resources of Woodward’s (2005) interventionist conception of causation. The viability of these responses has been challenged by Gebharter (2017a), who argues that the causal exclusion argument is vindicated by the theory of causal Bayesian networks (CBNs). Since the interventionist conception of causation relies crucially (...) on CBNs for its foundations, Gebharter’s argument appears to cast significant doubt on interventionism’s antireductionist credentials. In the present article, we both (1) demonstrate that Gebharter’s CBN-theoretic formulation of the exclusion argument relies on some unmotivated and philosophically significant assumptions (especially regarding the relationship between CBNs and the metaphysics of causal relevance), and (2) use Bayesian networks to develop a general theory of causal inference for multi-level systems that can serve as the foundation for an antireductionist interventionist account of causation.

In Explaining Attitudes, Baker argues that we should treat our everyday practices as relevant to metaphysical debates, resulting in a stance of realism with respect to intentional explanations. In this chapter I will argue that if one is going to be a practical realist about anything, it should be the self, or subject of attention. I will use research on attention combined with the stance of practical realism to argue in favor of a substantive self. That is, I will present (...) an account of the self that directs and controls attention, in line with our everyday view of the self. I will contrast this account with what I call the “illusion view,” which presents the self and its apparent causal power in the case of attention as an illusion. My account of the self will make use of several of Baker's ideas, including non-reductive materialism and broad supervenience. (shrink)

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.

In the current article and contrary to a widespread assumption, I argue that Humeanism and ontological emergence can peacefully coexist. Such a coexistence can be established by reviving elements of John Stuart Mill’s philosophy of science, in which an idiosyncratic account of diachronic emergence is associated with extensions of the Humean mosaic and the correlative coming into being of new best system laws, which have the peculiarity of being temporally indexed. Incidentally, this reconciliation of Humeanism and emergence allows for conceiving (...) the autonomy of the special sciences in an interesting way, consistently with the reductionist ideal of a unified science.

The concept of truthmaking, the idea that when a statement is true, there is typically something about the world in virtue of which it is true, has garnered much interest in recent metaphysics. Often, the motivation has been the thought that truthmaking can provide a new perspective on an important issue. This paper evaluates the claim that truthmaking can play a substantive role in defining an unproblematic notion of emergence. For despite playing an important role in philosophical discourse over the (...) past 100 years, it has often been thought that there is something mysterious about the notion of emergence. It has recently been argued, however, that once emergent properties are characterized as those that, while “ontologically dependent” are yet needed as truthmakers emergence and emergent properties prove unproblematic. In response, I argue that there is reason to doubt that truthmaking can play an important role in formulating an unproblematic yet recognizable notion of emergence. I argue that it is consistent with truthmaking being unable to play a substantive role in emergentism that truthmaking can play a more significant role in characterizing an attractive middle ground between reductive and nonreductive physicalism.

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. (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.

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)

The causal exclusion problem, as presented by Jaegwon Kim, is aimed to show that non-reductive physicalism is self-contradictory, as it is impossible for effects already having a sufficient physical cause to have a distinct mental cause. One possible reply to Kim’s argument is compatibilism — a view within non-reductive physicalism that states that psychophysical supervenience is able to sustain the coexistence of efficacious mental and physical causes. The aim of this paper is to describe the currently most popular compatibilist strategy, (...) as well as to present and evaluate some objec- tions to it. First, I sketch the causal exclusion problem and show how compatibilists could un- dermine the causal exclusion principle using counterfactual analysis. Then I point out why this is a troublesome and insufficient tool and what challenges await compatibilism in its current form. (shrink)

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)

The thesis of multiple realisation that Borsboom et al. are relying on should not be taken for granted. In dissolving the apparent multiple realisation, the reductionist research strategies in psychopathology research (the Research Domain Criteria [RDoC] framework, in particular) are bound to lead to eliminativism rather than reductionism. Therefore, Borsboom et al. seem to be aiming at a wrong target.

One of the most important problems of twentieth century analytic philosophy concern the place of the mind – and in particular, of consciousness and intentionality – in a physical universe. Brian Loar’s essays in the philosophy of mind in this volume include his major contributions in this area. His central concern was how to understand consciousness and intentionality from the subjective perspective, and especially, how to understand subjectivity in a physical universe. He was committed to the reality and reliability of (...) the subjective perspective; and he found that subjective phenomena like intentionality and consciousness are, in a certain sense, ineliminable and irreducible to objective ones. At the same time he believed that intentionality and consciousness are grounded in the physical. One of his great contributions was showing how to reconcile these two positions by being a conceptual and explanatory anti-reductionist about both consciousness and intentionality but a metaphysical reductionist nonetheless. He had a deep commitment to both physicalism and to the reality and significance of the subjective point of view. (shrink)

Reductionists say things like: all mental properties are physical properties; all normative properties are natural properties. I argue that the only way to resist reductionism is to deny that causation is difference making (thus making the epistemology of causation a mystery) or to deny that properties are individuated by their causal powers (thus making properties a mystery). That is to say, unless one is happy to deny supervenience, or to trivialize the debate over reductionism. To show this, I argue that (...) if properties are individuated by their causal powers then, surprisingly, properties are individuated by necessary co-exemplification. (shrink)

Review of Robert Kirk's The Conceptual Link From Physical To Mental (Oxford University Press, 2013).

The exclusion problem is meant to show that non-reductive physicalism leads to epiphenomenalism: if mental properties are not identical with physical properties, then they are not causally efficacious. Defenders of a difference-making account of causation suggest that the exclusion problem can be solved because mental properties can be difference-making causes of physical effects. Here, we focus on what we dub an incompatibilist implementation of this general strategy and argue against it from a non-reductive physicalist perspective. Specifically, we argue that incompatibilism (...) undermines either the non-reductionist or the physicalist aspirations of non-reductive physicalism. (shrink)

This paper responds to recent criticisms of the idea that true causal claims, satisfying a minimal “interventionist” criterion for causation, can differ in the extent to which they satisfy other conditions—called stability and proportionality—that are relevant to their use in explanatory theorizing. It reformulates the notion of proportionality so as to avoid problems with previous formulations. It also introduces the notion of conditional independence or irrelevance, which I claim is central to understanding the respects and the extent to which upper (...) level explanations can be “autonomous”.

In earlier work, I proposed and defended a formulation of physicalism that was distinctive in appealing to a carefully-defined relation of physical realization. Various philosophers (Robert Francescotti, Daniel Stoljar, Carl Gillett, and Susan Schneider) have since presented challenges to this formulation. In the present paper, I aim to show that these challenges can be overcome.

This paper considers the extent to which the notion of truthmaking can play a substantive role in defining physicalism. While a truthmaking-based approach to physicalism is prima facie attractive, there is some reason to doubt that truthmaking can do much work when it comes to understanding physicalism, and perhaps austere metaphysical frameworks in general. First, despite promising to dispense with higher-level properties and states, truthmaking appears to make little progress on issues concerning higher-level items and how they are related to (...) how things are physically. Second, it seems that truthmaking-based approaches to physicalism will have a difficult time addressing the status of truthmaking itself without, in effect, appealing to the resources of alternative ways of conceptualizing physicalism.

The aim of this editorial introduction is twofold. First, Sects. 1–8 offer a critical introduction to the metaphysical character of physicalism. In those sections, I present and evaluate different ways in which proponents of physicalism have made explicit the metaphysical dependence that is said to hold between the non-physical and the physical. Some of these accounts are found to be problematic; others are shown to be somewhat more promising. In the end, some important lessons are drawn and different options for (...) physicalists are presented. Second, in Sect.9, the six papers that comprise the special issue are introduced and summarized. (shrink)

On the heels of the advance since the twentieth-century of wholly physicalist accounts of human persons, the influence of materialist ontology is increasingly evident in Christian theologizing. To date, the contemporary literature has tended to focus on anthropological issues (e.g., whether the traditional soul / body distinction is viable), with occasional articles treating physicalist accounts of such doctrines as the Incarnation and Resurrection of Jesus cropping up, as well. Interestingly, the literature to date, both for and against this influence, is (...) dominated by philosophers. The present volume is a collection of philosophers and theologians who advance several novel criticisms of this growing trend toward physicalism in Christian theology. The present collection definitively shows that Christian physicalism has some significant philosophical and theological problems. No doubt all philosophical anthropologies have their challenges, but the present volume shows that Christian physicalism is most likely not an adequate accounting for essential theological topics within Christian theism. Christians, then, should consider alternative anthropologies. (shrink)

Attention is essential to the life of the mind, a central topic in cognitive science, neuroscience, and psychology. Traditional debates in philosophy stand to benefit from greater understanding of the phenomenon, whether on the nature of the self, the foundation of knowledge, the natural basis of consciousness, or the origins of action and responsibility. This book is at the crossroads of philosophy of mind and cognitive science, offering a new theoretical stance on the concept of attention and how it intersects (...) with other functions of the mind, such as perception, consciousness, and action. It presents attention as directed by a subject, essential for perception, but not consciousness or action. By taking seriously the existence of a subject it stands against current trends in philosophy and cognitive science. This book offers an account of the subject and its role in attention that will both help motivate a subject-centered account and avoid some of the common criticisms regarding its existence. It engages with work by many philosophers, psychologists, and neuroscientists, including Block, Campbell, Dickie, Husserl, James, Koch, Mack and Rock, Merleau-Ponty, Treisman, and Wu. (shrink)

I look at some central positions in the mental causation debate – reductionism, emergentism, and nonreductive physicalism – on the hypothesis that mental causation is intelligible. On this hypothesis, mental causes and their effects are internally related so that they intelligibly “fit”, analogous to the way puzzle pieces interlock, or shades of red fall into order within a color sphere. The assumption of intelligibility has what I take to be a welcome consequence: deciding among rivals in the mental causation debate (...) could end up to be largely an empirical matter. (shrink)

It has often been thought that compositional variation across systems that are similar from the point of view of the special sciences provides a key point in favor of the multiple realization of special science kinds and in turn the broadly nonreductive consequences often thought to follow from multiple realization. Yet in a series of articles, and culminating in The Multiple Realization Book, Tom Polger and Larry Shapiro argue that an account of multiple realization demanding enough to yield such nonreductive (...) consequences implies that compositional variation is far less significant for the multiple realization of special science kinds than many have supposed. I argue, in contrast, that even on this demanding account, lower-level compositional variation may frequently support the multiple realization of special science kinds across the systems of interest, and that there is a good explanation for where Polger and Shapiro go wrong in drawing the contrary conclusion. I consider but reject Carl Gillett’s claim that different views about the significance of compositional variation for multiple realization phenomena should be traced to implicit disagreement about the metaphysics of realization.

A review of recent work on physicalism, focusing on what it means to say nothing exists over and above the physical, how "the physical" should be defined, and the causal argument for physicalism.

The main contention of this article is that current approaches to ontological emergence are not comprehensive, in that they share a common bias that make them blind to some conceptual space available to emergence. In this article, I devise an alternative perspective on ontological emergence called ‘flat emergence’, which is free of such a bias. The motivation is twofold: not only does flat emergence constitute another viable way to fulfill the initial emergentist promise, but it also allows for making sense (...) of some emergence ascriptions that traditional accounts are unable to accommodate.

How should thought and consciousness be understood within a view of the world as being through-and-through physical? Many philosophers have proposed non-reductive, levels-based positions, according to which the physical domain is fundamental, while thought and consciousness are higher-level processes, dependent on and determined by physical processes. In this book, Kevin Morris's careful philosophical and historical critique shows that it is very difficult to make good metaphysical sense of this idea - notions like supervenience, physical realization, and grounding all fail to (...) articulate a viable non-reductive, levels-based physicalism. Challenging assumptions about the mind-body problem and providing new perspectives on the debate over physicalism, this accessible and comprehensive book will interest scholars working in metaphysics, philosophy of mind, and philosophy of science.

Some recent arguments defending the genuine causal efficacy of the mental have been relying on empirical research on neuroprosthetics. This essay presents a critical analysis of these arguments. The problem of mental causation, and the basic idea and results of neuroprosthetics are reviewed. It is shown how appealing to the research on neuroprosthetics can be interpreted to give support to the idea of mental causation. However, it does so only in a rather deflationary sense: by holding the mental identical with (...) the neural. So contrary to what the arguments have been assuming, neuroprosthetics cannot be used to argue for nonreductive physicalism. It can rather be taken to illustrate just the opposite: how the mental and the physical are identical. (shrink)

Scientists and philosophers frequently speak about levels of description, levels of explanation, and ontological levels. In this paper, I propose a unified framework for modelling levels. I give a general definition of a system of levels and show that it can accommodate descriptive, explanatory, and ontological notions of levels. I further illustrate the usefulness of this framework by applying it to some salient philosophical questions: (1) Is there a linear hierarchy of levels, with a fundamental level at the bottom? And (...) what does the answer to this question imply for physicalism, the thesis that everything supervenes on the physical? (2) Are there emergent properties? (3) Are higher-level descriptions reducible to lower-level ones? (4) Can the relationship between normative and non-normative domains be viewed as one involving levels? Although I use the terminology of “levels”, the proposed framework can also represent “scales”, “domains”, or “subject matters”, where these are not linearly but only partially ordered by relations of supervenience or inclusion.
