Dualism

Abstract is a noun. Abstract is, also, a verb. Thus, abstraction. Explaining nouns. And verbs.

We have to go all the way back to Euclid, and, actually, before, to figure out the basis for representation, and therefore, interpretation. Which is, pure and simple, the conservation of a circle. As articulated by Foucault, Deleuze, and Nietzsche. 'Pi' (in mathematics) is the background state for everything (a.k.a. 'mind').Providing the explanation for (and the current popularity, and, thus, the 'genius' behind) NFT (non fungible tokens). 'Reality' has, finally, caught up with the 'truth.'.

Pi in mathematics is mind in Nature, explaining the tokenization of 'reality.'.

We have to begin with the pyramid (pi-diameter-circumference). In order to understand an 'idea.' And, the history of ideas.

I seek to explicate the ways in which the soul is deemed immaterial in two main strands of Islamic philosophy, and then consider some arguments for the immateriality of the soul. To do so, I first overview Avicenna’s theory of the spiritual incipience (al-ḥudūth al-rūḥānī) of the soul and his version of substance dualism. I will then discuss Mullā Ṣadrā’s view of the physical incipience (al-ḥudūth al-jismānī) of the soul and how the soul emerges and develops towards immateriality on his (...) account. I then overview and discuss five of the most important arguments presented by these two great Muslim philosophers in favor of the immateriality of the soul. To do so, I will also point out some of the main contemporary physicalistic views of the nature of mind and mental states. I will then argue that arguments for the immateriality of the soul – dealt with here – do not indeed target or challenge any significant versions of contemporary physicalism. Moreover, these arguments involve conflations of epistemological or ontological issues. (shrink)

While imagination was a major concern for Descartes throughout his work, Cartesian scholars have paid little attention to this faculty, especially regarding to the Meditations of First Philosophy. This article highlights the epistemic role of imagination in the First Meditation. I argue that the way Descartes’s conception of imagination is elaborated in the First Meditation helps question our interpretation of his dualism, and enables us to formulate the hypothesis that imagination belongs to the essence of the mind. It results that (...) Descartes’s dualism should not be interpreted as separation (or separability) regarding to existence. (shrink)

Getting to the ‘heart’ of the human ‘mind…’ X, XX, XXX.

Zero and One is Circumference and Diameter.

Conservation of a circle explains (the human) mind.

The main topic of this paper is the mind-body problem. The author analyzes it in the context of Hus- serlian phenomenology. The key texts for the analysis and interpretation are Descartes’ magnum opus “Meditations on the First Philosophy” and Husserl’ last work “The Crisis of European Sciences and Transcendental Phenomenology”. The author claims that already in Descartes’ text instead of one mind-body problem, one can find two: the ontological mind-body problem (mind-brain relation) and conceptual one (“mind” and “body” as concepts). (...) In Descartes’ “Meditations”, the ontological level is explicit, while the conceptual level is implicit. In Husserl’s “Crisis”, on the other hand, the situation is different: the conceptual level of the problem (as the opposition between transcendental phenomenology and natural sciences) is explicit, while the ontological level is implicit. Nevertheless, it seems that Husserl has answers to both the “traditional” as well as the “conceptual” mind-body problems. (shrink)

Most discussions of near-death experiences (NDEs) in both the academic and popular literature contend that they establish ('prove') supernaturalism (about NDEs): they show that the mind is not the brain (and can continue after the brain stops functioning), and they bring us into contact with non-physical realms. I believe that the evidence provided by NDEs for supernaturalism is not persuasive, but I offer an alternative, naturalistic interpretation of these phenomena. On this interpretation, NDEs are 'real' in both senses of the (...) term: they really occur (people really have them, with the experiential content ascribed to them), and they are accurate. On this interpretation, NDEs are fundamentally about a journey from the known to the unknown, guided by a trusted mentor. Thus, NDEs accurately depict the possibilities for dying. Negative NDEs indicate the possibility of dying in cold, sterile, lonely circumstances, whereas positive NDEs point to the possibility of 'dying well', surrounded by loved ones. This is an interpretation that avoids the problems for supernaturalism of the gap between evidence and conclusion, and the commitment to causal interaction between physical and non-physical realms.

This monograph presents an interpretation of Descartes's dualism, which differs from the standard reading called 'classical separatist dualism' claiming that the mind can exist without the body. It argues that, contrary to what it is commonly claimed, Descartes’s texts suggest an emergent creationist substance dualism, according to which the mind is a nonphysical substance (created and maintained by God), which cannot begin to think without a well-disposed body. According to this interpretation, God’s laws of nature endow each human body with (...) the power to be united to an immaterial soul. While the soul does not directly come from the body, the mind can be said to emerge from the body in the sense that it cannot be created by God independently from the body. The divine creation of a human mind requires a well-disposed body, a physical categorical basis. This kind of emergentism is consistent with creationism and does not necessarily entail that the mind cannot survive the body. This early modern view has some connections with Hasker’s substance emergent dualism (1999). Indeed, Hasker states that the mind is a substance emerging at one time from neurons and that consciousness has causal powers which effects cannot be explained by physical neurons. An emergent unified self-existing entity emerges from the brain on which it acts upon. For its proponents, Hasker’s view explains what Descartes’s dualism fails to explain, especially why the mind regularly interacts with one and only one body. After questioning the notion of emergence, the author argues that the theory of emergent creationist substance dualism that she attributes to Descartes is a more appropriate alternative because it faces fewer problems than its rivals. This monograph is valuable for anyone interested in the history of early modern philosophy and contemporary philosophy of mind. (shrink)

Abstract We motivate and develop an A-theory of time and probe its implied interpretation of quantum mechanics. It will emerge that, as a first take, the time of relativity is a B-series and the time of quantum mechanics is an A-series. There is philosophical motivation for the idea that mutual quantum measurement happens when and only when the systems’ A-series become one mutual A-series. This accounts almost trivially for many quantum phenomena, including that the electrons of a Bell pair do (...) not have definite spins ‘until’ measurement, as ‘until’ here is an A-series notion. This version of the paper is in the process of being re-formatted for submission to a journal. (shrink)

This article explores three ways in which a cognitively entrenched mindreading (or 'theory of mind') system may bias our thinking as cognitive scientists. One issues in a form of tacit dualism, impacting scientific debates about phenomenal consciousness. Another leads us to think that our own minds are easier to know than they really are, influencing debates about self-knowledge, and about mindreading itself. And the third results in a bias in favour of empiricist over nativist accounts of cognitive development. The discussion (...) throughout is tentative and speculative, and can be regarded as an appeal for caution, as well as a call for further research. (shrink)

Non-locality is one of the great mysteries of quantum mechanics (qm). There is a new realist interpretation of qm on the table whose notion of time incorporates both of McTaggart's A-series and B-series. In this philosophically motivated interpretation there is no fact of the matter as to whether the 'now' of one system is the 'now' of another system, until measurement. But this reproduces the idea that the spins of a Bell pair of electrons do not become definite 'until' measurement. (...) And this almost trivially allows for non-locality. (shrink)

Why is there a 'hard problem' of consciousness? Why do we seem unable to grasp intuitively that physical brain processes can be identical to experiences? Here I comment on the 'meta-problem' (Chalmers, 2018), based on previous ideas (Storm, 2014; 2018). In short: humans may be 'inborn dualists' ('neuroscepticism'), because evolution gave us two (types of) brain systems (or functional modes): one (Sp) for understanding relatively simple physical phenomena, and another (Sm) specialized for mental phenomena. Because Sp cannot deal with the (...) immense complexity of the brain processes underlying consciousness, it represents them as fundamentally different from nonmental physical phenomena (dualist intuition), using 'simulations' to produce 'Sm-type understanding'/predictions that seems radically different from 'Sp-type understanding'. (By analogy, different sensory modalities, handled by distinct brain systems, evoke qualitatively different experiences.) Brain systems for Sp representations of our brain processes never evolved, because they would be useless. When lacking a single 'template' matching different aspects of reality (objective vs. subjective = simulated), complementary 'models' are needed ('neuro-complementarity'), like the wave–particle duality in quantum mechanics. Thus, it seems plausible that Sp and Sm evolved because they were needed to cope with different challenges, and that 'problem intuitions' are side effects of these useful but different brain systems.

I argue that there is a version of (quasi-Armstrongian) weak illusionism that intelligibly relates phenomenal concepts and introspective opacity, accounts for the (hard) problem intuitions Chalmers highlights (modal, epistemic, explanatory, and metaphysical), and undermines the most important arguments Chalmers deploys against type-B and type-C materialisms. If this is successful, we can satisfactorily account for the meta-problem of consciousness, mollify our hard problem intuitions, and remain genuine realists about phenomenal experience.

Solving the meta-problem of consciousness requires, among other things, explaining why we are so reluctant to endorse various forms of illusionism about the phenomenal. I will try to tackle this task in two steps. The first consists in clarifying how the concept of consciousness precludes the possibility of any distinction between 'appearance' and 'reality'. The second consists in spelling out our reasons for recognizing the existence of something that satisfies that concept.

The meta-problem of consciousness is the problem of explaining why we have the intuition that there is a hard problem of consciousness. David Chalmers briefly notes that my phenomenal powers view may be able to answer to this challenge in a way that avoids problems (having to do with avoiding coincidence) facing other realist views. In this response, I will briefly outline the phenomenal powers view and my main arguments for it and—drawing in part on a similar view developed by (...) Harold Langsam—discuss how more precisely its answer to the challenge would go. (shrink)

Chalmers' (2018) meta-problem of consciousness emphasizes unexpected common ground between otherwise incompatible positions. We argue that the materialist should welcome discussion of the meta-problem. We suggest that the core of the metaproblem is the seeming arbitrariness of subjective experience. This has an unexpected resolution when one moves to an interventionist account of scientific explanation: the same interventions that resolve the hard problem should also resolve the meta-problem.

Chalmers (2018) raises three challenges for Michael Graziano's attention schema theory. Our aim in this paper is to bolster Graziano's attention schema theory with some tools and insights from the predictive processing framework, in order to respond to the challenges raised by Chalmers and more generally strengthen the theory. We will first introduce the attention schema theory and the three challenges raised by Chalmers, before outlining our application of predictive processing to the theory and how it can resolve these challenges, (...) thus offering a solution to the meta-problem. (shrink)

The hard problem of consciousness is about how we could explain in physicalist terms why we are conscious. The meta-problem of consciousness is about how we could explain why we have a hard problem of consciousness. In this note I argue that the phenomenal concept strategy can in principle provide a satisfactory solution to the meta-problem.

I present two caveats to the meta-problem challenge to theories of consciousness. Chalmers suggests that a theory of consciousness that solves the hard problem should also inform us about the meta-problem, and vice versa. The first caveat is the view that mechanism M, the mechanism through which content becomes conscious, may be neutral with respect to the content it renders conscious. This means that there can be no systematic connection between M and conscious content. The second caveat concerns how we (...) should treat the problem intuitions fueling the meta-problem. I argue that we should award them no special status with respect to their explanatory power in relation to the hard problem. (shrink)

The meta-problem of consciousness is the problem of explaining why we have problem intuitions about consciousness, why we intuitively think that conscious experience cannot be scientifically explained. In his discussion of this problem, David Chalmers briefly considers the possibility of giving a 'genealogical' solution, according to which problem intuitions are 'accidents of cultural history' (2018, p. 33). Chalmers' response to this solution is largely dismissive. In this paper, we defend the viability of a genealogical solution. Our strategy is to focus (...) on a particular problem intuition: the thought that the phenomenal character of colour experience is irreducibly subjective. We use the history of the inverted spectrum thought experiment as a window into how various philosophers have thought about colour experience. Our genealogy reveals that problem intuitions about colour are not timeless, but instead arise in a specific historical context, one that, in large part, explains why we have these intuitions. (shrink)

The meta-problem of consciousness is framed as a route into investigating why there are problems in understanding consciousness by describing the mechanisms underpinning our tendency to describe consciousness as problematic, and the evolutionary origins of these mechanisms. This is framed as a means of uniting illusionists and realists toward a common goal, but this supposes that the only viable form of illusionism is what I call 'hard-wired' illusionism, under which phenomenal judgments are a direct product of natural selection. I argue (...) that, instead, 'soft-wired' illusionism is more plausible, where phenomenal judgments are seen to be cultural phenomena. Since the problem of consciousness arises from a flawed theory of consciousness, pointing out the mechanisms underlying expression of the theory and the historical origins of the theory will not suffice to tell us why the theory is problematic. As such, the meta-problem is exclusionary toward soft-wired illusionism. (shrink)

We argue for the mind’s independence from the body. We do so by making several moves. First, we analyze two popular kinds of reasons which have swayed many to adopt the independence of the mind from the body. Second, we advance an argument from the ontology of intentionality against the identity thesis, according to which the mind is identical to the brain. We try to show how intentionality is not reducible to or identical to the physical. Lastly, we argue that, (...) contrary to what many materialists contend, the concept of a mind, understood as an immaterial substance, existing independently of the body is both coherent and empirically evidenced.

The familiar narrative about the early days of analytic philosophy tells us of its triumph over the needless metaphysical excesses of its immediate forerunners, the idealists. In one form or another, idealism was the paramount philosophical view of the 19th century. Nowadays, however, the bulwarks of idealism are largely abandoned. Few defend the view, and fewer still are willing to take the time to consider its claims seriously. Materialism and dualism dominate the philosophical landscape.

I argue that our direct experience and some physical facts do not go well with an understanding of perception as a mechanism producing a representation of a ''truly'' outer world. Instead, it is much more coherent to treat what is traditionally considered an image in this context as a closed structure equipped in its own ontology, replacing the ''truly'' outer one from the point of view of an agent possessing it. In such a framework, the notion of existence is taken (...) to be defined by consciousness in a way similar to qualia, making it subjective on the one hand, and reducing it to a tool on the other. This implies, in turn, that we need a form of mind-brain dualism; the best we can do in such circumstances about explaining consciousness as an epistemic device - a role intuitively imposing itself in a variety of situations - is to embed it in an abstract ontology merely serving the purpose of a ''true'' reality with the help of the mind-brain link. Obviously, the approach favors subjectivity as a foundation in the ontological sense. Objectivity is considered here only as a suitably understood product from an ''observer's'' point of view, although a functional and useful one. The paper is addressed to readers with interest in both the mind-body problem and ontological foundations of present-day physics, specifically quantum theory. The main conclusion can be absorbed without the quantum part, although it is a bit less convincing then. (shrink)

The aim of this work is to expose the Cartesian Model of the mind in Cognitive Archaeology and point out how it relates to the questions behind this branch of archaeology. Based on this, some of the premises assumed by the Cartesian Model and how they influence the formulation to the problem of epistemological relativism in the branch are explained. According to this problem, since there is no way to evaluate hypotheses in this research area, the investigations on cognition, based (...) on archaeological evidence, are unjustified. Finally, some alternative approaches to the Cartesian Model and its research agendas are summarized. (shrink)

The causal pairing problem allegedly renders nonphysical minds causally impotent. This article demonstrates how a dualist view I call neo-Thomistic hylomorphism can circumnavigate the causal pairing problem. After explicating the problem and hylomorphism, I provide an account of causal pairing that appeals to a foundational tenet of hylomorphism. Subsequently, I suggest that a prominent view of consciousness in theoretical neuroscience—the integrated information theory—can learn from hylomorphism and likewise account for causal pairing.

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)

Following Chalmers, I take the most promising response to the meta-problem to be a realizationist one on which (roughly) consciousness plays a role in realizing the processes that explain why we think that there is a hard problem of consciousness. I favour an interactionist dualist version of realizationism on which experiences are non-physical states that non-redundantly cause problem judgments. This view is subject to the challenges of specifying laws that would enable experiences to cause problem judgments and of explaining why (...) it's not a lucky coincidence that experiences' causal and rational powers converge on problem judgments. I propose a strategy for solving the meta-problem and meeting these challenges. According to it, a fundamental teleological law operates on normative features of experiences in ways that bias experiences towards causing effects that they rationalize, including problem judgments. I conclude by applying the strategy to other luck-avoidance challenges. (shrink)

This paper first explores in detail a regenerated theory in philosophy of mind, known among contemporary philosophers as ‘emergentism’. By distinguishing strong and weak versions of the theory, I explain two important explanatory challenges presented by physicalists against this theory. In the following, I provide a brief overview of Sadr al-Muta’allihin’s theory of the incipience and degrees of the soul, examining similarities and differences between this theory and strong emergentism. Then, underlining the main aspects of similarity between the two theories, (...) I consider the challenges presented by physicalists against emergentism as reconstructible against Sadra’s theory. Surveying some explanations by Sadraean philosophers of the soul-body relationship, I ultimately argue that Sadra’s theory is inadequate in face of the objections and doubts raised by contemporary physicalists. My assessment is that Sadra’s philosophy is in need of further development to meet those explanatory challenges. (shrink)

In his celebrated 1974 essay “What Is It Like to Be a Bat?,” Thomas Nagel stages a human-bat encounter to illustrate and support his claim that “subjective experience” is irreducible to “objective fact”: because Nagel cannot experience the world as a bat does, he will never know what it is like to be one. In Nagel’s account, heterogeneity is figured negatively—as a failure or lack of resemblance—and functions to constrain his knowledge of bats. Today, as white-nose syndrome threatens bat populations (...) across North America, might figuring heterogeneity positively, as a condition of creativity, open up new modes of receptivity and responsiveness to species extinctions? This essay turns to philosophies of becoming and to recent research in the biological sciences to explore this possibility. I suggest that attending to the heterogeneity of experience alerts us to more public dimensions of our being and may thereby work against the tendency to understand and experience ourselves as self-contained and closed off from one another and the world we share in common. This may in turn enhance our sense of entanglement with the events, bodies, and forces on the “outside” of experience, including bats and the white-nose syndrome with which they are afflicted today. Such an affirmation of heterogeneity as a condition of creativity holds the greatest promise for multispecies ethics today, I propose, when it is joined to an affirmation of incompatibilities within and between things as a real force of suffering and destruction in a heterogeneous world.

According to the ‘conceivability argument’ [1] it’s conceivable that a conscious human being H may have a perfect physical duplicate H* who isn’t conscious, [2] whatever is conceivable is possible, therefore [3] H* may possibly exist. This paper argues that the conceivability argument can’t help in discussion of the ‘mind–body problem’ even if [2] is allowed to be true. This is not because [1] is false, but because we don’t and can’t know enough about the nature of the physical to (...) know whether or not [1] is true. This follows from ‘the silence of physics’—the fact that physics neither does nor can tell us about the intrinsic non-structural nature of the physical, and the consequences of this fact for any adequate account of the meaning of the word ‘physical’.

Susan Schneider argues that physicalism must be false if abstracta are part of the physicalist's dependence base. In opposition to her view, here I set out some reasons to think that abstracta in general, including abstracta that are woven into the dependence base, are something physicalists can countenance with consistency.

The knowledge argument is an argument for dualism that claims that there are both physical and non-physical facts, something we can know by reflecting on 'Mary' who is aware of all scientific data about colours but has yet to see any. I reject the dualist conclusion and instead provide a new physicalist response that I call 'bifactualism'. Bifactualism is a novel physicalist account comprising two elements. First, like dualism, it distinguishes between two kinds of facts: general and particular facts. Second, (...) unlike dualism, it claims that the general/particular distinction may explain facts about experience. There are certain facts that go undocumented in what is expressible in the language of the physical sciences because the language of the physical sciences concerns only general facts, whereas experience, I argue, essentially involves learning particular facts. Thus, I argue that the case of Mary does not support mind/body dualism, and instead provides at least equal reason to support bifactualism. Since the general/particular distinction is one we are stuck with regardless of the status of mind, bifactualism emerges as a more parsimonious and hence preferable account of experience. (shrink)

This paper critically evaluates Jonathan Lowe's arguments for his non-Cartesian substance dualism. Sections 1 and 2 set out the principal claims of NCSD. The unity argument proposed in Lowe is discussed in Section 3. Throughout his career Lowe offered spirited attacks on reductionism about the self. Section 4 evaluates the anti-reductionist argument that Lowe offers in Subjects of Experience, an argument based on the individuation of mental events. Lowe offers an inventive proposal that the semantic distinction between direct and indirect (...) reference delineates the metaphysical boundary between self and world, and uses this as a further argument against reductionism about the self. This proposal is discussed in Sections 5 and 6. (shrink)

There is a perception that the substantial data from psi research is indicative of support for a dualistic worldview. In this paper, we present an overview of this perspective as discussed in the works of John Beloff, Charles Tart, David Rousseau, Ed Kelly, and Larry Dossey. Following this, we discuss the refutation of the dualist view from the point of the definition of non-material, and provide a possible definition of non-material, and the role of consciousness in quantum mechanics. We conclude (...) that these criteria are sufficient to reject a dualist perspective in the analysis of psi data, until the validity of all possible physicalist-reductionist views have been exhausted. In our analysis, the next question guiding a psi research programme is how psi occurs and what its mechanics are. (shrink)

We agree with critics that enactive, sensorimotor, and ecological accounts of conscious experience do not in and of themselves fully deflate the hard problem of consciousness. As we noted in our earlier work, even if an extended account of cognition and intentionality allows us to be rid of qualia by deflating the dualism between intentionality and phenomenal experience, the heart of the hard problem, namely subjectivity, still remains. We argue that in order to resolve or deflate the hard problem the (...) hypothesis of extended consciousness needs to be understood as an expression of neutral monism and can quite naturally be understood that way.

Demons have the power to cause temptations in us, and Christian materialism implies the supervenience of temptations on brain states. This in turn implies that demons bring about temptations by causally interfering with our brains. But if they have such an ability to affect the physical world, it is mysterious why they do not wreak more havoc than they do both to our brains and in the world more generally. Substance dualism provides an elegant solution: demonic temptation is not a (...) species of soul-to-brain causation, but soul-to-soul, and we don’t need to suppose demons have the power to directly affect the physical world. Materialist solutions, in contrast, are ad hoc. (shrink)

The article formulates and substantiates the philosophical epistemological principle, which generalizes the principle of complementarity of Bohr to all phenomena of reality. The general complementarity principle is formulated as follows: the rational side of reality and its cognition and its associated irrational side of reality and its cognition are complementary to each other. The general principle of complementarity allows one to search for phenomena of duality in various fields, grouping them according to rational and irrational signs.

In the twentieth century there was a fundamental debate on the problem of consciousness within a philosophical perspective. In fact, one of the most difficult tasks for a philosopher of mind is to comprehend the role of phenomenal properties. Some philosophers want to convince us that phenomenal properties are completely reducible to physical properties, whereas others admit that our consciousness possesses non physical qualities. My aim in this paper is to provide a dualist perspective in order to solve the problem (...) of consciousness. There exist some intrinsic and subjective aspects of our perceptual experience of the world that cannot be identical with brain states. I maintain that the phenomenal facts are ontologically distinct from the physical facts and they are not reducible to them. I will demonstrate this thesis by taking into account the debate about whether conceptual analysis is required for reductive explanation. In the first two sections, I will present the main arguments against reductive physicalism and I will analyze the debate about conceptual analysis developed by Block & Stalnaker and Chalmers & Jackson. In the final section, I shall show that we can’t derive phenomenal truths from a complete physical knowledge of the world. Since we can’t support a reduction just on a posteriori identities between different kinds of phenomena, I maintain that the lack of a necessary conceptual connection between phenomenal properties and physical properties excludes reductive physicalism. Consequently, if we want to solve the mind-body problem we definitely need a dualist perspective. (shrink)
