Neutral monism is a position in metaphysics defended by Mach, James, and Russell in the early twentieth century. It holds that minds and physical objects are essentially two different orderings of the same underlying neutral elements of nature. This paper sets out some of the central concepts, theses and the historical background of ideas that inform this doctrine of elements. The discussion begins with the classic neutral monism of Mach, James, and Russell in the first part of the paper, then (...) considers recent neo-Russellian versions in the second half. The chances for a revival of neutral monism are probably slight; its key ideas and starting points lie far from those in contemporary philosophy of mind. A better route might be through the philosophy of science and a deeper understanding of causation. (shrink)

Consciousness fits uneasily into our conception of the natural world. On the most common conception of nature, the natural world is the physical world. But on the most common conception of consciousness, it is not easy to see how it could be part of the physical world. So it seems that to find a place for consciousness within the natural order, we must either revise our conception of consciousness, or revise our conception of nature. In twentieth-century philosophy, this dilemma is (...) posed most acutely in C. D. Broad’s The Mind and its Place in Nature . The phenomena of mind, for Broad, are the phenomena of consciousness. The central problem is that of locating mind with respect to the physical world. Broad’s exhaustive discussion of the problem culminates in a taxonomy of seventeen different views of the mental-physical relation.1 On Broad’s taxonomy, a view might see the mental as nonexistent , as reducible, as emergent, or as a basic property of a substance . The physical might be seen in one of the same four ways. So a four-by-four matrix of views results. At the end, three views are left standing: those on which mentality is an emergent characteristic of either a physical substance or a neutral substance, where in the latter case, the physical might be either emergent or delusive.

One of the main obstacles for panpsychism, the view that consciousness is fundamental and ubiquitous, is the difficulty of explaining how simple subjects could combine to form complex subjects. Known as the subject combination problem, it poses a possibly insurmountable challenge to the view. In this paper, I will assume that this challenge cannot be overcome and instead present a version of panpsychism that completely avoids talk of combination. Inspired by Gottfried Wilhelm Leibniz’s metaphysics of monads, I will focus on (...) a relational explanation of how simple subjects could constitute complex experiences, without them having to combine in virtue of their subjectivity. I call this view _monadic panpsychism_. Additionally, my proposal will not rely on emergence and so it will circumvent problems commonly faced by emergentist accounts. As I will argue, monadic panpsychism is preferable to combinatory and emergentist panpsychism because it faces a significantly less worrisome set of objections. Apart from being unaffected by the seemingly insuperable issue of subject combination, I will demonstrate that monadic panpsychism also has tools to address other kinds of the combination problem. That alone justifies the need for a new formulation of panpsychism, one which faces unique difficulties but also offers unique solutions. (shrink)

The Elephant and the Blind is a book about why we need a new culture of consciousness, and how to get it. A culture of consciousness (or Bewusstseinskultur) is a culture that values and cultivates the mental states of its members in an ethical and evidence-based way.

It is often claimed that Russellian monism carries a commitment to a structuralist conception of physics, on which physics describes the world only in terms of its spatiotemporal structure and dynamics. We argue that this claim is mistaken. On Russellian monism, there is more to consciousness, and to the rest of concrete reality, than spatiotemporal structure and dynamics. But the latter claim supports only a conditional claim about physics: _if_ structuralism about physics is true, then there is more to consciousness (...) and to the rest of concrete reality than physics describes. Given the fundamental nature of their position, Russellian monists can, we argue, deny the antecedent without inconsistency. We also draw out two significant consequences of that result. One is that it provides a response to some recent objections to Russellian monism, by Alyssa Ney and Eric Hiddleston. The other consequence concerns a line of reasoning known as _the structure and dynamics argument_—reasoning that is thought to motivate Russellian monism. In David J. Chalmers’s version, which is regarded as canonical, structuralism about physics is implied by a premise. If our main thesis is true, then that version is problematic, at least from the perspective of Russellian monists who take the argument to motivate their theory. However, we argue, the argument can be reformulated without relying on structuralism about physics. (shrink)

The Humility Thesis is a persistent thesis in contemporary metaphysics. It is known by a variety of names, including, but not limited to, Humility, Intrinsic Humility, Kantian Humility, Kantian Physicalism, Intrinsic Ignorance, Categorical Ignorance, Irremediable Ignorance, and Noumenalism. According to the thesis, we human beings, and any knowers that share our general ways of knowing, are irremediably ignorant of a certain class of properties that are intrinsic to material entities … Continue reading Humility Regarding Intrinsic Properties →.

The hard problem of consciousness is the problem of explaining the existence of subjective experience in a world that is purely physical. As the usual theories fail to provide an adequate explanation, many philosophers started looking for alternatives. One of such alternatives is panpsychism, which has been increasingly gaining attention in the past few decades. Panpsychism is the view that fundamental entities of the world—fundamental particles, for example—have some form of very simple consciousness. And, in the theory, it is that (...) spark that allows for the existence of more complex consciousness, such as in humans. However, panpsychism faces a major difficulty with what is called ‘the combination problem’. This is the problem that, even if we accept that fundamental entities have some form of simple consciousness, it is not clear how one could go from a plurality of micro consciousness to a complex unified macro consciousness. If we think that an atom is conscious, for example, this seems to imply that it is a subject, a conscious subject. But how do we get to a human subject, with a complex human brain? It seems difficult to understand how putting together many conscious subjects—e.g. atoms—could lead to a further conscious subject—e.g. a human. In this thesis I discuss panpsychism and some of the arguments that support it. In addition, I explain the combination problem and its different aspects, as well as how it relates to panpsychism and the hard problem of consciousness. Finally, I discuss a solution to the combination problem that I believe has not been given proper attention in contemporary philosophy, which is one provided by the philosopher Ken Wilber. His solution involves changing the conceptual framework of how we understand the relation between macro and micro subjects. I also apply his theory to the variations of the combination problem, discussing how we could approach these issues under a single coherent view. Although Wilber prefers the term pan-interiorism, his theory can be considered a type of holarchical panpsychism. (shrink)

The Integrated Information Theory is a leading scientific theory of consciousness, which implies a kind of panpsychism. In this paper, I consider whether IIT is compatible with a particular kind of panpsychism, known as Russellian panpsychism, which purports to avoid the main problems of both physicalism and dualism. I will first show that if IIT were compatible with Russellian panpsychism, it would contribute to solving Russellian panpsychism’s combination problem, which threatens to show that the view does not avoid the main (...) problems of physicalism and dualism after all. I then show that the theories are not compatible as they currently stand, in view of what I call the coarse-graining problem. After I explain the coarse-graining problem, I will offer two possible solutions, each involving a small modification of IIT. Given either of these modifications, IIT and Russellian panpsychism may be fully compatible after all, and jointly enable significant progress on the mind–body problem. (shrink)

I present an argument for panpsychism: the thesis that everything is conscious, or at least that fundamental physical entities are conscious. The argument takes a Hegelian dialectical form. Panpsychism emerges as a synthesis of the thesis of materalism and the antithesis of dualism. In particular, the key premises of the causal argument for materialism and the conceivability argument for dualism are all accommodated by a certain version of panpsychism. This synthesis has its own antithesis in turn: panprotopsychism, the thesis that (...) fundamental physical entities are protoconscious, also accommodates the key premises. Panpsychism and panprotopsychism are synthesized under Russellian monism, and then face an antithesis, the combination problem. The question of whether there is a new synthesis remains open.

The aim of this paper is twofold. First, our purpose is to propose and motivate a novel and scientifically informed variant of cosmopsychism, namely, the view that the experiences of ordinary subjects are ultimately grounded in an all-pervading cosmic consciousness. Second, we will demonstrate that this approach generates promising avenues for addressing familiar problems of phenomenal constitution. We use stochastic electrodynamics (SED) as the physical bedrock of our approach, supplementing it with key insights about the nature of consciousness long emphasized (...) in eastern philosophy and other wisdom traditions. We proceed to show that our approach substantiates an intriguing way of thinking about the dynamical emergence of ordinary consciousness from cosmic consciousness, identifying the latter with the vacuum state of quantum field theory. Finally, we argue that the present approach is well suited to address problems of phenomenal constitution, in particular as they pertain to the qualities and structure of experience and to the generation of subjects.

I argue that experiences can have microphenomenal structures, where the macrophenomenal properties we introspect are realized by non-introspectible microphenomenal properties. After explaining what it means to ascribe a microstructure to experience, I defend the thesis against its principal philosophical challenge, discuss how the thesis interacts with other philosophical issues about experience, and consider our prospects for investigating the microphenomenal realm.

The most pressing worry for panpsychism is arguably the combination problem, the problem of intelligibly explaining how the experiences of microphysical entities combine to form the experiences of macrophysical entities such as ourselves. This chapter argues that the combination problem is similar in kind to other problems of mental combination that are problems for everyone: the problem of phenomenal unity, the problem of mental structure, and the problem of new quality spaces. The ubiquity of combination problems suggests the ignorance hypothesis, (...) the hypothesis that we are ignorant of certain key facts about mental combination, which allows the panpsychist to avoid certain objections based on the combination problem.

This thesis explores the possibility of composite consciousness: phenomenally conscious states belonging to a composite being in virtue of the consciousness of, and relations among, its parts. We have no trouble accepting that a composite being has physical properties entirely in virtue of the physical properties of, and relations among, its parts. But a long­standing intuition holds that consciousness is different: my consciousness cannot be understood as a complex of interacting component consciousnesses belonging to parts of me. I ask why: (...) what is it about consciousness that makes us think it so different from matter? And should we accept this apparent difference? (shrink)

What is the mind? Is consciousness a process in the brain? How do our minds represent the world? Philosophy of Mind: Classical and Contemporary Readings is a grand tour of writings on these and other perplexing questions about the nature of the mind. The most comprehensive collection of its kind, the book includes sixty-three selections that range from the classical contributions of Descartes to the leading edge of contemporary debates. Extensive sections cover foundational issues, the nature of consciousness, and the (...) nature of mental content. Three of the selections are published here for the first time, while many other articles have been revised especially for this volume. Each section opens with an introduction by the editor. Philosophy of Mind is suitable for students at all levels and also for general readers. (shrink)

I endorse a 12-word metaphysics. [1] Stoff ist Kraft ≈ being is energy. [2] Wesen ist Werden ≈ being is becoming. [3] Sein ist Sosein ≈ being is qualit[ativit]y. [4] Ansichsein ist Fürsichsein ≈ being is mind. [1]–[3] are plausible metaphysical principles and unprejudiced consideration of what we know about concrete reality obliges us to favor [4], i.e. panpsychism or panexperientialism, above all other positive substantive proposals. For [i] panpsychism is the most ontologically parsimonious view, given that the existence of (...) conscious experience is certain and that panpsychism doesn’t posit the existence of any kind of stuff other than conscious experience. [ii] A question also arises about why metaphysicians have posited the existence of something for which there is zero evidence: non-experiential concrete reality. The question is the more pressing because of the silence of physics: physics with its numbers and equations is perfectly silent on the question of the intrinsic non-structural nature of reality.

I discuss the apparent discrepancy between the qualitative diversity of consciousness and the relative qualitative homogeneity of the brain's basic constituents, a discrepancy that has been raised as a problem for identity theorists by Maxwell and Lockwood (as one element of the ‘grain problem’), and more recently as a problem for panpsychists (under the heading of ‘the palette problem’). The challenge posed to panpsychists by this discrepancy is to make sense of how a relatively small ‘palette’ of basic qualities could (...) give rise to the bewildering diversity of qualities we, and presumably other creatures, experience. I argue that panpsychists can meet this challenge, though it requires taking contentious stands on certain phenomenological questions, in particular on whether any familiar qualities are actual examples of ‘phenomenal blending’, and whether any other familiar qualities have a positive ‘phenomenologically simple character’. Moreover, it requires accepting an eventual theory most elements of which are in a certain explicable sense unimaginable, though not for that reason inconceivable. Nevertheless, I conclude that there are no conclusive reasons to reject such a theory, and so philosophers whose prior commitments motivate them to adopt it can do so without major theoretical cost.

The measurement problem of quantum theory is discussed, and the difficulty of trying to solve it within the confines of a local, Lorentz-invariant physics is emphasised. This leads to the obvious suggestion to seek a solution beyond physics, in particular, by introducing the concept of consciousness. The resulting dualistic model, in the natural form suggested by quantum theory, is shown to differ in several respects from the classical model of Descartes, and to suggest solutions to some of the long-standing problems (...) concerning the relation of consciousness to the physical world.

There occurred in the twentieth century the most remarkable episode in the history of human thought. A number of thinkers denied the existence of something we know with certainty to exist: consciousness, conscious experience. Others held back from the Denial, as we may call it, but claimed that it might be true --a claim no less remarkable than the Denial. This paper documents some aspects of this episode, with particular reference to two things. First, the development of two views which (...) are forms of the Denial --philosophical behaviourism, and functionalism considered as a doctrine in the philosophy of mind-- from a view that does not in any way involve the Denial: psychological methodological behaviourism. Second, the rise of a way of understanding naturalism --materialist or physicalist naturalism-- that wrongly takes naturalism to entail the Denial. (shrink)

The debate over physicalism in philosophy of mind can be seen as concerning an inconsistent tetrad of theses: (1) if physicalism is true, a priori physicalism is true; (2) a priori physicalism is false; (3) if physicalism is false, epiphenomenalism is true; (4) epiphenomenalism is false. This paper argues that one may resolve the debate by distinguishing two conceptions of the physical: on the theory‐based conception, it is plausible that (2) is true and (3) is false; on the object‐based conception, (...) it is plausible that (3) is true and (2) is false. the paper also defends and explores the version of physicalism that results from this strategy.

My overall aim in this thesis is to elucidate the precise nature of Russell's mature 'neutral monist' metaphysic. I show how an understanding of it has been hampered by pervasive misunderstandings. The approach I take is an historical one, and my account reveals that, after his adoption of neutral monism in 1918, there were no radical changes in his worldview, and certainly no lurch from a supposed quasi-phenomenalistic system prior to 1921, to a causal theory of perception after 1927. Instead, (...) the earlier system is not as phenomenalistic as is sometimes supposed and his later philosophy is a development, not a repudiation, of the themes in the earlier. Russell sought to show how his metaphysic dovetails with the outcome of modern physics in his 1927 book The Analysis of Matter. I seek to show how a proper understanding of modern physics indeed leads to Russellian conclusions. I also discuss the implications of quantum mechanics for metaphysics – a task which Russell could not have performed when he wrote The Analysis of Matter, since QM was still very much in a state of flux. I show how Russell moved from empiricism to a naturalistic position in the theory of knowledge,and in doing so supplied a definitive solution to Hume's scepticism. Once again, the usual perception of him as an “empiricist” fails to do justice to the complexity and subtlety of his philosophy. Finally, I argue that Russell's solution to the mind-body problem is the only one with any chance whatsoever of being true. In all this I seek to show how Russell's philosophy has been unjustly neglected in contemporary debates and how it can provide elegant solutions to contemporary philosophical puzzles in the philosophy of science, epistemology and the mind-body problem.

How does the modern scientific conception of time constrain the project of assigning the mind its proper place in nature? On the scientific conception, it makes no sense to speak of the duration of a pain, or the simultaneity of sensations occurring in different parts of the brain. Such considerations led Henri Poincaré, one of the founders of the modern conception, to conclude that consciousness does not exist in spacetime, but serves as the basic material out of which we must (...) create the physical world. The central claim of Sensorama is that Poincaré was substantially correct. The best way to reconcile the scientific conception of time with the evidence of introspection is through a phenomenalist metaphysic according to which consciousness exists in neither time nor space, but serves as a basis for the logical construction of spacetime and its contents.

This thesis introduces the Problem of Consciousness as an antinomy between Physicalism and Primitivism about the phenomenal. I argue that Primitivism is implausible, but is supported by two conceptual gaps. The ‘–tivity gap’ holds that physical states are objective and phenomenal states are subjective, and that there is no entailment from the objective to the subjective. The ‘–trinsicality gap’ holds that physical properties are extrinsic and phenomenal qualities are intrinsic, and that there is no entailment from the extrinsic to the (...) intrinsic. Stoljar’s Epistemic View (EV) suggests that we have a limited conception of the physical world, and that the apparent inexplicability of consciousness is merely a symptom of our ignorance. I argue that EV must satisfy two conditions which require it to specify the content of our ignorance. EV’s best hope is a Russellian appeal to our ignorance of intrinsic physical properties. After arguing in favour of this ignorance claim, I show how it undermines the –trinsicality gap. However, I suggest that the –tivity gap cannot be dealt with by the Russellian ignorance hypothesis, nor by any other version of EV. However, I then argue that the Russellian ignorance hypothesis can still be deployed as half of a hybrid account of the phenomenal. Representationalist theories of consciousness have difficulty with the –trinsicality gap, but show promise with the –tivity gap. Specifically, Kriegel’s Self-Representationalism indicates that there can indeed be an entailment from objective physical states to subjective phenomenal states. This paves the way for my hybrid account of consciousness: the subjectivity of a phenomenal state is the product of its self-representational structure, and the qualitative character of a phenomenal state is the product of the epistemically inaccessible intrinsic physical properties involved in its implementation.

I defend a physicalistic version of ontological emergence; qualia emerge from the brain, but are physical properties nevertheless. First, I address the following questions: what are the central tenets of physicalistic ontological emergentism; what are the relationships between these tenets; what is the relationship between physicalistic ontological emergentism and non-reductive physicalism; and can there even be a physicalistic version of ontological emergentism? This discussion is merely an attempt to clarify exactly what a physicalistic version of ontological emergentism must claim, and (...) to show that the view is at least coherent. I then defend the view from objections, for example, Kim’s (Philos Stud 95:3–36, 1999) attempt to apply a version of his exclusion argument to ontological emergentism. I conclude by offering a positive argument for the view: given certain empirical evidence concerning the organization of the brain, physicalism might have to endorse ontological emergentism to avoid epiphenomenalism.

In the waking state, in the absence of meta-awareness, mind wandering with specific contents can lead to negative mood. Such negative mood can be incorporated into dreaming according to the continuity hypothesis of dreaming. In this paper we argue that in the presence of what we call ‘sustained phenomenal meta-awareness’, negative mood would not follow mind wandering in waking. Sustained phenomenal meta-awareness has a non-sensory, non-affective phenomenal character. It is essentially intransitive, prereflectively self-aware, non-propositional, non-conceptual and devoid of subject-object structure. (...) In other words, this unique kind of meta-awareness is non-representational. Evidence is then provided that such sustained phenomenal meta-awareness can be incorporated into the subsequent dream state as non-dual lucid dreaming in which, again, no negative mood would arise. Based on the latter observation, we have coined the term ‘mindful mind wandering’ and defined it as mind wandering in the presence of sustained phenomenal meta-awareness. We argue that not only does mindful mind wandering not lead to negative mood in waking, but also its incorporation into dreaming, as non-dual lucid dreaming, result in a state that is free of negative affection.
