By treating colours as sui generis intrinsic properties of objects we can maintain that (1) colours are causally responsible for colour experiences (and so agree with the physicalist) and (2) colours, along with the similarity and difference relations that colours bear to one another, are presented to us by casual observation (and so agree with the dispositionalist). The major obstacle for such a view is the causal overdetermination of colour experience. Borrowing and expanding on the works of Sydney Shoemaker and (...) Stephen Yablo, the paper offers a solution.

I argue that the phenomenal properties of conscious visual experiences are properties of the mind-independent objects to which the subject is perceptually related, mediated by the subject's practical understanding of their sensorimotor relation to those properties. This position conjoins two existing strategies for explaining the phenomenal character of perceptual experiences: accounts appealing to perceivers’ limited, non-inferential access to the details of their sensory relation to the environment, and the relationalist conception of phenomenal properties. Bringing these two positions together by emphasizing (...) their sensorimotor common ground allows each one to respond to damaging objections using the resources of the other. The resulting ‘sensorimotor relationalism’ about conscious vision provides a promising schema for explaining phenomenal properties of perceptual states, replacing ‘Hard’ questions with tractable ones about the perceptual relation and its sensorimotor underpinnings.

The quantum theory of de Broglie and Bohm solves the measurement problem, but the hypothetical corpuscles play no role in the argument. The solution finds a more natural home in the Everett interpretation.

I develop an account of naturalness in physics which demonstrates that naturalness assumptions are not restricted to narrow cases in high-energy physics but are a ubiquitous part of how interlevel relations are derived in physics. After exploring how and to what extent we might justify such assumptions on methodological grounds or through appeal to speculative future physics, I consider the apparent failure of naturalness in cosmology and in the Standard Model. I argue that any such naturalness failure threatens to undermine (...) the entire structure of our understanding of intertheoretic reduction, and so risks a much larger crisis in physics than is sometimes suggested; I briefly review some currently-popular strategies that might avoid that crisis.

I address the problem of indefiniteness in quantum mechanics: the problem that the theory, without changes to its formalism, seems to predict that macroscopic quantities have no definite values. The Everett interpretation is often criticised along these lines, and I shall argue that much of this criticism rests on a false dichotomy: that the macroworld must either be written directly into the formalism or be regarded as somehow illusory. By means of analogy with other areas of physics, I develop the (...) view that the macroworld is instead to be understood in terms of certain structures and patterns which emerge from quantum theory (given appropriate dynamics, in particular decoherence). I extend this view to the observer, and in doing so make contact with functionalist theories of mind. (shrink)

Abstract. Contrary to proposals that seek a harmonious integration of “science and religion” or “science and spirituality,” I argue that contemporary scientific and philosophical work at the mind-brain interface gives us reason to be skeptical of many of the claims found within religious spiritualities. Religious spiritualities typically presume commitment to strong versions of metaphysical dualism, while contemporary mind science gives us every reason to think that the mind is the brain. If materialism is true, what becomes of spirituality? Materialism or (...) naturalism is widely understood to be an anti-religious position with corrosive effects on morality. I correct this impression, arguing that materialism offers a compelling account of moral objectivity and is fully compatible with an appreciation for many aspects of religion. I further suggest that nothing precludes dialogue and conversation between naturalists and religious believers. (shrink)

Neurotheology is a fast-growing field of research. Combining philosophy of mind, neuroscience, and religious studies, it takes a new approach to old questions on religion. What is religion and why do we have it? Neurotheologists focus on the search for the neural correlate of religious experiences. If we can trace religious experiences to specific parts of the brain, chances are we can reduce religion as such to that grey soggy matter as well. This article predicts neurotheology will not be able (...) to locate the neural correlate of religious experiences. As we cannot decide phenomenally what makes an experience religious, neurologically we cannot find its correlate either. That is, if there are fixed neural correlates to begin with, because their existence is still a matter of debate. In addition, religious experiences seem to be a kind of experience, like emotional or relational experiences, making them indistinguishable from similar nonreligious experiences. Even if one manages to trace the neural correlate of religious experiences, neurotheology will still not be able to account for the rise of religion without resorting to theories from other disciplines. In the end, we do not know enough about consciousness and the way it relates to the brain to make conclusive claims about the search for religious states of consciousness. It seems, however, that even though neurotheology could provide fascinating insights in the workings of the religious brain, on its own, it will prove unable to explain religion fully. (shrink)

The relationship of minds, bodies, and persons has been a central topic of debate in Western philosophy and theology. This article reviews the ongoing debates about the relationship and nature of bodies, minds, and persons among contemporary Christian analytic philosophers and theologians. The first two parts present some general theological constraints for philosophical theories of persons and describe the basic concepts used (substance, property, supervenience, and physicalism). The views themselves fall into three broad categories. Dualists think that persons are either (...) identical with or partly constituted by non-physical souls. On this view, there are immaterial substances and properties. Hylomorphists maintain that persons are composites of bodies and the souls that inform them. Finally, physicalists claim that there are no immaterial parts to persons. Instead, persons are composed of bodies and brains, the mental properties they have supervene on physical properties.

En esta revista, argumenté en favor de la naturaleza consciente de las creencias de primera persona. En un artículo más reciente, Miguel Ángel Sebastián trata de mostrar que tal argumento no es sólido. Aquí procedo a lidiar con sus tres críticas principales. En primer lugar, sostengo que el argumento es válido si conocer una creencia de primera persona consiste en creer que uno la tiene. Defiendo también que no hay ninguna regresión al infinito de creencias conscientes de orden superior que (...) sea dañina. En segundo lugar, argumento que la noción de conciencia en juego es aquella que es relevante en la discusión acerca de la naturaleza de la conciencia y del inconsciente. Por último, reviso la justificación del principio para mostrar que no prejuzga la cuestión. (shrink)

The Extended Mind Hypothesis has given rise to stimulating philosophical debates about the boundaries of the realm of the cognitive. This paper first investigates the usefulness of a “mark of the cognitive,” and then focuses on two accounts that aim to provide such a mark, put forward by Fred Adams and Rebecca Garrison on one side and Mark Rowlands on the other. The paper provides a critical assessment of these accounts and uses empirical work on emotion regulation in infants to (...) unearth some crucial challenges that any attempt at offering a mark of the cognitive should address.

Can a person’s degree of wellbeing be affected by things that do not enter her experience? Experientialists deny that it can, extra-experientialists affirm it. The debate between these two positions has focused on an argument against experientialism—the experience machine objection—but few arguments exist for it. I present an argument for experientialism. It builds on the claim that theories of wellbeing should not only state what constitutes wellbeing, but also which entities are welfare subjects. Moreover, the claims it makes about these (...) two issues should have a certain coherence with each other. I argue that if we accept a particular plausible answer to the second question—namely that all and only sentient beings are welfare subjects—extra-experientialist theories face a problem of coherence. While this problem can typically be solved, doing so will involve steps that are unattractive. On experientialist theories, on the other hand, the answer to these questions cohere perfectly.

According to the dominant computational approach in cognitive science, cognitive agents are digital computers; according to the alternative approach, they are dynamical systems. This target article attempts to articulate and support the dynamical hypothesis. The dynamical hypothesis has two major components: the nature hypothesis (cognitive agents are dynamical systems) and the knowledge hypothesis (cognitive agents can be understood dynamically). A wide range of objections to this hypothesis can be rebutted. The conclusion is that cognitive systems may well be dynamical systems, (...) and only sustained empirical research in cognitive science will determine the extent to which that is true. (shrink)

In “Absent Qualia and the Mind-Body Problem,” Michael Tye (2006) presents an argument by which he claims to show the inconceivability of beings that are functionally equivalent to phenomenally conscious beings but lack any qualia. On that basis, he concludes that qualia can be fully defined in functional terms. The argument does not suffice to establish the claimed results. In particular it does not show that such absent qualia cases are inconceivable. Tye’s argument relies on a principle P according to (...) which the exchange of isomorphic states between functionally equivalent systems will preserve their equivalence. If they were functionally equivalent before the exchange, they will also be so after. Consideration of the contextual nature of realization shows that Principle P is not a general truth as Tye claims, and his argument against the possibility of absent qualia thus fails. (shrink)

David Chalmers' dancing qualia argument is intended to show that phenomenal experiences, or qualia, are organizational invariants. The dancing qualia argument is a reductio ad absurdum, attempting to demonstrate that holding an alternative position, such as the famous inverted spectrum argument, leads one to an implausible position about the relation between consciousness and cognition. In this paper, we argue that Chalmers' dancing qualia argument fails to establish the plausibility of qualia being organizational invariants. Even stronger, we will argue that the (...) gap in the argument cannot be closed. (shrink)

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

There is reason to expect a reasonable account of a priori knowledge to be linked with an account of the nature of conceptual thought. Recent “two-dimensionalist” accounts of conceptual thought propose an extremely direct connection between the two: on such views, being in a position to know a priori a large number of non-trivial propositions is a necessary condition of concept-possession. In this paper I criticize this view, by arguing that it requires an implausibly internalist and intellectualist conception of capacities (...) we bring to bear in applying concepts in experience. Empirical concept-application depends on the exercise of a variety of capacities, many of which can be grouped together under the general label “recognitional”. As I argue, two-dimensionalism cannot accommodate a plausible account of such capacities. This suggests that the link between a priori knowledge and the nature of conceptual thought is not as direct as twodimensionalists take it to be. I close by briefly sketching a different way to think of that link. (shrink)

Modal rationalism includes the thesis that ideal primary positive conceivability entails primary possibility. Modal monism is the thesis that the space of logically possible worlds is coextensive with the space of metaphysically possible worlds. In this paper I explore the relation between the two theses. My aim is to show that the former thesis implies the latter thesis, and that problems with the latter make the former implausible as a complete picture of the epistemology of modality. My argument explores the (...) relation between logical modality and metaphysical modality. (shrink)

We often decide whether a state of affairs is possible by trying to mentally depict a scenario where the state in question obtains . These mental acts seem to provide us with an epistemic route to the space of possibilities. The problem this raises is whether conceivability judgments provide justification-conferring grounds for the ensuing possibility-claims . Although the question has a long history, contemporary interest in it was, to a large extent, prompted by Kripke's utilization of modal intuitions in the (...) course of propounding certain influential theses in the philosophy of language and mind. The interest has been given a further boost by the recent two-dimensional approach to the Kripkean framework. In this paper, I begin by providing a detailed examination of a most recent attempt to defend the thesis and argue that it is unsuccessful. This is followed by presenting my own gloss on Kripke's explanation of the illusions of contingency and I close by raising a general problem intended to undermine the prospects for a successful defense of the thesis.

Consciousness is seen as a difficult “binding” problem. Binding, a process where different sensations evoked by an item are associated in the nervous system, can be viewed as a process similar to associative learning. Several reports that consciousness is associated with some form of memory imply that different forms of memories have a common feature contributing to consciousness. Based on a proposed synaptic mechanism capable of explaining different forms of memory, we developed a framework for consciousness. It is based on (...) the formation of semblance of sensory stimulus from (1) synaptic semblances when excitatory postsynaptic potentials arrive at functionally LINKed postsynaptic membranes, and (2) network semblances when these potentials summate to elicit action potential initiating activity in a network of neurons. It is then possible to derive a framework for consciousness as a multi-dimensional semblance. According to this framework, a continuum of semblances formed from background sensory stimuli and oscillating neuronal activities serve to maintain consciousness. Feasibility of this framework to explain various physiological and pathological states of consciousness, its subjective nature and qualia is examined. (shrink)

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.

A major part of the mind–body problem is to explain why a given set of physical processes should give rise to perceptual qualities of one sort rather than another. Colour hues are the usual example considered here, and there is a lively debate as to whether the results of colour vision science can provide convincing explanations of why colours actually look the way they do. The internal phenomenological structure of colours is considered here in some detail, and a comparison is (...) drawn with sounds and their synthesis. This paper examines the type of explanation that is needed, and it is concluded that it does not have to be reductive to be effective. What needs to be explained more than anything is why inverted hue scenarios are more intuitive than other sensory inversions: and the issue of physicalism versus dualism is argued to be of only marginal relevance.

Given that for (...) us to conceive of an immortal life we must project onto it our own view of what it is like to live our own life and given that an immortal life may not be anything like the life we live, we cannot conceive of what it is like to be immortal.

At the very heart of the mind-body problem is the question of the nature of consciousness. It is consciousness, and in particular _phenomenal_ consciousness, that makes the mind-body relation so deeply perplexing. Many philosophers hold that no defi nition of phenomenal consciousness is possible: any such putative defi nition would automatically use the concept of phenomenal consciousness and thus render the defi nition circular. The usual view is that the concept of phenomenal consciousness is one that must be explained by (...) means of specifi c examples and associated comments. (shrink)

That experience requires a subject is all but uncontroversial. It is surprising, then, that contemporary philosophers of mind generally focus on experiences at the expense of subjects. Herein, I argue that beyond the qualitative character of phenomenology, there is a discrete further fact—the subjective character of phenomenology—that calls out for explanation. Similar views have recently been endorsed by both Zahavi and Kriegel, but a comparison of the ways they have framed the issue suggests there are two discrete questions afoot: in (...) virtue of what does subjective phenomenology exist whatsoever, and in virtue of what might one’s subjective phenomenology differ from that of one’s perfect duplicate? The second question—that of individuative subjective phenomenology—is my primary concern, and its answer seems to me to require the invocation of haecceities: non-qualitative, non-duplicable properties that uniquely individuate objects. In other words, I suggest that the property of being the very subject that one is enters essentially into the phenomenological character of all one’s experiences. (shrink)

This paper offers a novel argument against the phenomenal intentionality thesis (or PIT for short). The argument, which I'll call the extended mind argument against phenomenal intentionality, is centered around two claims: the first asserts that some source intentional states extend into the environment, while the second maintains that no conscious states extend into the environment. If these two claims are correct, then PIT is false, for PIT implies that the extension of source intentionality is predicated upon the extension of (...) phenomenal consciousness. The argument is important because it undermines an increasingly prominent account of the nature of intentionality. PIT has entered the philosophical mainstream and is now a serious contender to naturalistic views of intentionality like the tracking theory and the functional role theory (Loar 1987, 2003; Searle 1990; Strawson 1994; Horgan and Tienson 2002; Pitt 2004; Farkas 2008; Kriegel 2013; Montague 2016; Bordini 2017; Forrest 2017; Mendelovici 2018). The extended mind argument against PIT challenges the popular sentiment that consciousness grounds intentionality. (shrink)

Augmented reality (AR) technologies function to ‘augment’ normal perception by superimposing virtual objects onto an agent’s visual field. The philosophy of augmented reality is a small but growing subfield within the philosophy of technology. Existing work in this subfield includes research on the phenomenology of augmented experiences, the metaphysics of virtual objects, and different ethical issues associated with AR systems, including (but not limited to) issues of privacy, property rights, ownership, trust, and informed consent. This paper addresses some epistemological issues (...) posed by AR systems. I focus on a near-future version of AR technology called the Real-World Web, which promises to radically transform the nature of our relationship to digital information by mixing the virtual with the physical. I argue that the Real-World Web (RWW) threatens to exacerbate three existing epistemic problems in the digital age: the problem of digital distraction, the problem of digital deception, and the problem of digital divergence. The RWW is poised to present new versions of these problems in the form of what I call the augmented attention economy, augmented skepticism, and the problem of other augmented minds. The paper draws on a range of empirical research on AR and offers a phenomenological analysis of virtual objects as perceptual affordances to help ground and guide the speculative nature of the discussion. It also considers a few policy-based and designed-based proposals to mitigate the epistemic threats posed by AR technology. (shrink)

Discussion of partial grounds that aren't parts of full grounds; definition of full grounding in terms of partial grounding.

That there is an epistemological difference between the mental and the physical is well- known. Introspection readily generates knowledge of one’s own conscious experience, but fails to yield evidence for the existence of anything physical. Conversely, empirical investigation delivers knowledge of physical properties, but neither finds nor requires us to posit conscious experience. In recent decades, a series of neo-Cartesian arguments have emerged that rest on this epistemological difference and purport to demonstrate that mind-brain identity is false and that consciousness (...) is not even realized by or supervenient on physical properties. Where Descartes argued he could clearly and distinctly conceive mind and body as existing separately, contemporary anti-physicalists hold that the conceivability of worlds in which actual world correlations between physical and phenomenological properties fail shows that these correlations are contingent rather than logically or metaphysically necessary. Together with Descartes, they conclude from conceivability that identity, as well as strong supervenience, is false. 1 If the argument of this paper is correct, however, then there is an argument for dualism that arises from the epistemological distinction, is grounded in the Meditations, and is yet distinct from the " 1 " conceivability arguments pursued both by Descartes and contemporary anti-physicalists. Furthermore, the argument is immune to the standard objections to conceivability arguments: its conclusion follows even if there are a posteriori identities between physical and phenomenal properties.

Clinical fields of the “sciences of the mind” (psychotherapy, psychiatry, etc.) lack integrative conceptual frameworks that have explanatory power. Mainly descriptive-classificatory taxonomies like DSM dominate the field. New taxonomies such as Research Domain Criteria (RDoC) aim to collect scientific knowledge regarding “systems” for “processes” of the brain. These terms have a supradisciplinary” meaning if they are considered in context of Systems Science. This field emerges as a platform of theories like general systems theory, catastrophe theory, synergetics, chaos theory, etc. It (...) provides a lot of abstract concepts, constructs, methods and models. We assume that these tools also enable theoretical integration in the diversified field of clinical practice in the sciences of the mind. Additionally, systems thinking in clinical psychology improves conceptual links to currently network-oriented neurobiology. However, clear definitions of systemic terms are necessary to emerge from their mainly metaphorical use. Here we revise mainly terms like “structure”, “process” and “dynamics” as they are used already in psychology, psychoanalysis, psychopathology and psychiatry in an ill-defined way. For instance, affective-cognitive structures like “life space” or “object representations” can be seen as products of mental processing. These structures, in turn, modulate dynamics of mental processes. Additionally, we suggest a coupled network concept of emotions and motivations as the main subsystem that modulates mental dynamics that results in a qualitative systemic model of the mind. Finally, we assume that a revisited systemic approach could improve interdisciplinary understanding of the mental. ystem for mental dynamics. In this context, we assume that a revisited systemic approach could improve interdisciplinary understanding of the mental. (shrink)

The present paper proposes a route to modal claims that allows us to infer to certain possibilities even if they are sensorily unimaginable and beyond the evidential capacity of stipulative imagining. After a brief introduction, Sect. 2 discusses imaginative resistance to help carve a niche for the kinds of inferences about which this essay is chiefly concerned. Section 3 provides three classic examples, along with a discussion of their similarities and differences. Section 4 recasts the notion of potential explanation in (...) Lipton’s (Inference to the best explanation, Routledge, Abingdon, 2004) in order to accommodate inferences to possibility claims; Sect. 5 then attempts to characterise a principle underlying such inferences. Section 6 concludes by discussing how the proposal relates to other modal epistemologies, with emphasis on the potential of such inferences to produce genuinely new ideas. (shrink)

In this paper I attempt to develop a notion of responsibility (semantic responsibility) that is to the notion of belief what epistemic responsibility is to the notion of justification. 'Being semantically responsible' is shown to involve the fulfilment of cognitive duties which allow the agent to engage in the kind of reason-laden discourses which render her beliefs appropriately sensitive to correction. The concept of semantic responsibility suggests that the notion of belief found in contemporary philosophical debates about content implicitly encompasses (...) radically different classes of beliefs. In what follows I make those different types explicit, and sketch some implications for naturalisation projects in semantics and for accounts of the (putative) non-conceptual content of perceptual experiences.

In the decade and a half since the appearance of Varela, Thompson and Rosch's workThe Embodied Mind,enactivism has helped to put experience and consciousness, conceived of in a distinctive way, at the forefront of cognitive science. There are at least two major strands within the enactive perspective: a broad view of what it is to be an agent with a mind; and a more focused account of the nature of perception and perceptual experience. The relation between these two strands is (...) discussed, with an overview of the papers presented in this volume. (shrink)

In this paper I provide an exposition and critique of the Organic View of Ethical Status, as outlined by Torrance (2008). A key presupposition of this view is that only moral patients can be moral agents. It is claimed that because artificial agents lack sentience, they cannot be proper subjects of moral concern (i.e. moral patients). This account of moral standing in principle excludes machines from participating in our moral universe. I will argue that the Organic View operationalises anthropocentric intuitions (...) regarding sentience ascription, and by extension how we identify moral patients. The main difference between the argument I provide here and traditional arguments surrounding moral attributability is that I do not necessarily defend the view that internal states ground our ascriptions of moral patiency. This is in contrast to views such as those defended by Singer (1975, 2011) and Torrance (2008), where concepts such as sentience play starring roles. I will raise both conceptual and epistemic issues with regards to this sense of sentience. While this does not preclude the usage of sentience outright, it suggests that we should be more careful in our usage of internal mental states to ground our moral ascriptions. Following from this I suggest other avenues for further exploration into machine moral patiency which may not have the same shortcomings as the Organic View. (shrink)

Restrictivists hold that visual experience only represents low-level properties such as shape, spatial location, motion, color, etc. Expansionists contend that visual experience also represents high-level properties such as being a pine tree. I outline a new approach to support expansionism called the conflict cross-modal argument. What I call the conflict cross-modal effects occur when at least two perceptual systems disagree about some property belonging to a common stimulus, and this disagreement causes a change in the representational and phenomenal content of (...) the perceptual experience associated with one, or both, modalities. The conflict cross-modal argument works by accepting that if a property figures in a conflict cross-modal effect, then prima facie that property is a strong common sensible between the two modalities, and vision and another modality disagree about a property that is high-level for vision. After outlining this argument, and showing how it overcomes two obstacles that face traditional methods employed to defend expansionism, I turn to the well known Mcgurk effect as a case where vision and audition disagree about phoneme properties in order to employ my argument for the conclusion that phoneme properties are represented in visual experience. The upshot is that since phoneme properties are high-level for vision, we have an argument supporting expansionism. (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.

The physical realm is causally closed, according to physicalists like me. But why is it causally closed, what metaphysically explains causal closure? I argue that reductive physicalists are committed to one explanation of causal closure to the exclusion of any independent explanation, and that as a result, they must give up on using a causal argument to attack mind–body dualism. Reductive physicalists should view dualism in much the way that we view the hypothesis that unicorns exist, or that the Kansas (...) City Royals won the 2003 World Series: false, but not objectionable in any distinctively causal way. My argument turns on connections between explanation, counterfactuals, and inductive confirmation.
