Alter (The Matter of Consciousness: From the Knowledge Argument to Russellian Monism, GB: Oxford University Pres, 2023) argues for something surprising: despite being widely rejected by philosophers, including Frank Jackson himself, Jackson’s knowledge argument succeeds. Alter’s defense of Jackson’s argument is not only surprising; it’s also exciting: the knowledge argument, if it’s sound, underscores the power of armchair philosophy, the power of pure thought to arrive at substantial conclusions about the world. In contrast, I aim to make a case for (...) something unsurprising and unexciting: that the knowledge argument does not succeed, or, even less far-reaching, that Alter’s defense of it is not persuasive. Mine is a classic file-drawer thesis, but what it has going for it is that it’s true, or so I think, and hope to illustrate why you should too. (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.

Parsimony considerations are ubiquitous in the literature concerning the nature of mental states. Other things being equal, physicalist views are preferred over dualist accounts on the grounds of the fact that they do not posit new fundamental properties in addition to the physical ones. This paper calls into question the widespread assumption that parsimony can provide reasons for believing that physicalism is a better candidate than dualism for solving the mind–body problem. After presenting the theoretical core of physicalism and dualism, (...) I make explicit the meta-metaphysical assumptions the physicalist relies on when leveraging parsimony to support her view. In particular, the physicalist takes for granted that parsimony has an epistemic value in metaphysics. This point, however, is rather controversial. I argue that the most promising way to account for the epistemic value of parsimony is to ground it in the epistemic value of modesty, a higher-level theoretical virtue that has to do with the epistemic risk of a theory. Unfortunately for the physicalist, the modesty rationale does not ultimately favour physicalism over dualism. (shrink)

Nowadays, physicalism is arguably the received view on the nature of mental states. Among the arguments that have been provided in its favour, the inductive one seems to play a pivotal role in the debate. Leveraging the past success of materialistic science, the physicalist argues that a materialistic account of consciousness will eventually be provided, hence that physicalism is true. This article aims at evaluating whether this strategy can provide support for physicalism. According to the standard objection raised against the (...) inductive line of reasoning, the argument would beg the question by assuming some sort of metaphysical uniformity between consciousness and the rest of the natural domain. Here, I concede that there is a way to avoid this criticism. However, I argue that the argument still fails to support physicalism due to a structural problem of justification transmission. (shrink)

How should the “physical” in “physicalism” be understood? I here set out systematic criteria of adequacy, propose an account, and show how the account meets those criteria. The criteria of adequacy focus on the idea of rational management: to vindicate philosophical practice, the account must make it plausible that we can assess various questions about physicalism. The account on offer is dubbed the “Ideal Naturalist Physics” account, according to which the physical is that which appears in an ideal theory that (...) both meets the explanatory goals of physics and is naturalist in a sense to be explained. The combination of these two provides a satisfying account of the physical that meets the criteria of adequacy and can be used to predict puzzle cases as well. (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.

Compatibilists respond to the problem of causal exclusion for nonreductive physicalism by rejecting the exclusionist’s ban on overdetermination. By the compatibilist’s lights there are two forms of overdetermination, one that’s problematic and another that is entirely benign. Furthermore, multiple causation by “tightly related” causes requires only the benign form of overdetermination. Call this the tight relation strategy for avoiding problematic forms of overdetermination. To justify the tight relation strategy, modal compatibilists appeal to a widely accepted counterfactual test. The argument of (...) this paper is that the counterfactual test fails to legitimize the tight relation strategy as it fails to adequately distinguish between problematic and benign overdetermination. Contrary to modal compatibilists, modal dependence does not suffice for benignity. I conclude by arguing that adequately addressing overdetermination worries requires a much heavier metaphysical burden than modal compatibilists have typically recognized. (shrink)

In this paper, I argue that the first and the third premises of the zombie argument cannot be jointly true: zombies are either inconceivable beings or the possible existence of them does not threaten the physicalist standpoint. The tenability of the premises in question depends on how we understand the concept of a zombie. In the paper, I examine three popular candidates to this concept, namely zombies are creatures who lack consciousness, but are identical to us in their (a) functional (...) organization, (b) entire physical makeup, and (c) microphysical structure. The main aim of the paper is to argue that none of these conceptions conveys a consistent zombie-concept to us, which, at the same time, would be dangerous for physicalism. In the conclusion, I argue that the source of this failure can be found in the logical fallaciousness of the argument, namely the premises simply presuppose the truth of the conclusion. (shrink)

Physicalism is thought to entail that mental properties supervene on microphysical properties, or in other words that all God had to do was to create the fundamental physical properties and the rest came along for free. In this paper, we question the all-god-had-to-do reflex.

Substance dualism is the view that there are two fundamentally different kinds of substances: physical and mental. By contrast, according to property dualism there is only one kind of substance (physical) but two fundamentally different kinds of properties: physical and mental. Property nominalism is the view that there are neither repeatable nor non-repeatable fundamentally predicable entities (i.e. neither universals nor tropes) and that things being a certain way or being related in a certain way must ultimately be accounted for in (...) terms of concrete particulars. In this paper, we consider a number of different kinds of property nominalism and argue that none of them sits well with property dualism. We pay special attention to the question of what it could mean for a property to count as mental given different nominalistic accounts of properties. Our conclusion is that property nominalism and property dualism are not a stable match. This is surprising, since property dualism has usually been understood as a thesis that is neutral about the nature of fundamental ontological categories and the relation between them. (shrink)

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)

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’.

In The Matter of Consciousness (TMOC), I defend Frank Jackson’s (1982, 1986, 1995) knowledge argument, which poses a significant challenge to physicalism. I also argue that the knowledge argument leads to Russellian monism.

Physicalism is standardly construed as a form of monism, on which all concrete phenomena fall under one fundamental type. It is natural to think that monism, and therefore physicalism, is committed to a supervenience claim. Monism is true only if all phenomena supervene on a certain fundamental type of phenomena. Physicalism, as a form of monism, specifies that these fundamental phenomena are physical. But some argue that physicalism might be true even if the world is disorderly, i.e., not ordered by (...) supervenience relations in the way commonly supposed (Montero in J Philos 110:92–110, 2013; Leuenberger in Inquiry 57:151–174, 2014; Montero and Brown in Topoi 37(3):523–532, 2018; Zhong in Philos Stud 178(5):1529–1544, 2021). Unless these authors intend to challenge the claim that physicalism is a type of monism—a claim so central to the dialectic in philosophy of mind that rejecting it risks changing the subject—they are committed to challenging a supervenience requirement for monism. We argue that monism entails that there are substantial supervenience relations among concrete phenomena: relations that would not obtain in a disorderly world. Our argument thus has implications for debates about physicalism and supervenience, and sheds light on an under-discussed issue: what is implied by classifying a theory in the philosophy of mind as a form of monism? We also argue that physicalism’s commitment to monism creates problems for _via negativa_ physicalism, on which the physical is characterized negatively. (shrink)

The supervenience requirement on physicalism says roughly that if physicalism is true then mental properties supervene on fundamental physical properties. After explaining the basis of the requirement, I defend it against objections presented by Lei Zhong (“Physicalism without supervenience,” Philosophical Studies 178 (5), 2021: 1529–44), Barbara Gail Montero (“Must physicalism imply supervenience of the mental on the physical?” Journal of Philosophy 110, 2013: 93–110), and Montero and Christopher Devlin Brown (“Making room for a this-worldly physicalism,” Topoi 37 (3), 2018: 523–32).

Considering the most recent advances in artificial intelligence and biomechanics, a hypothetical future of physicalism is explored. It is concluded that a rational and sensible extrapolation of present and expected future advances in those two areas will have vast consequences in the physicalist view. In particular, it is also argued that consciousness cannot be defined in a simple general manner, but only understood through the observable and behavioural actions of humans or sufficiently advanced robots, which may be, at some future (...) time, indistinct. This last result is established by applying what we call Plato’s trap, and our main conclusion is a defence of physicalism. It is argued that human beings are robots which soon will be indistinguishable from suitable advanced man-made robots, which will in turn render many philosophical questions and objections to physicalism irrelevant and, in fact, quite similar in sense and importance to some philosophical medieval questions about God, the soul and immortality.

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.

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.

To resolve the hard problem of consciousness, we propose a systems-level theory of syner- gistic processes to account for sentience, consciousness, and mind. Subjectivity arises from interactive network processes within and between nature’s entangled, relational, and iter- ative elements. Searches for the physical cause or locus of consciousness and subjectivity are misguided given that consciousness emerges from processes with no single source. To account for the evolution and phenomenology of mind, our synergistic network account of consciousness dispenses with mind–body dualism, (...) it weakens boundaries between the material and the non-material, between the internal and the external, and emphasises synergistic processes and functionalities over outcome. The theory challenges psychology to abandon its cause–effect categorisations and implied mind–body dualism in favour of functional systems-level analyses to better account for relational processes and functions which unfold synergistically within and sustain nature’s complex networks of entangled elements.

This paper discusses and evaluates a recent argument for the conclusion that an attractive variety of Russellian monism ought to be regarded as a form of physicalism. According to this line of thought, if the Russellian’s “inscrutable” properties are held to ground not only experience, but also the physical structure of the world—and in this sense are not “experience-specific”—they thereby have an unproblematic place in physicalist metaphysics. I argue, in contrast, that there can be a sense in which the Russellian’s (...) inscrutables are experience-specific in a way that a physicalist probably ought to find objectionable, even if they play some role other than grounding experience. This will be the case, I argue, if certain worlds are taken to be possible, as they sometimes have: worlds of “bare structure” and worlds with what might be called “swapped inscrutables”. In this way, I claim that accepting certain possibilities has consequences for how one should understand the nature of the Russellian’s inscrutables and the place they have in physicalist metaphysics.
