Science of Consciousness

Os debates sobre a existência da consciência em animais não humanos vêm ganhando cada vez mais destaque nos círculos científicos e filosóficos ao redor do mundo. Um importante empecilho que a área atualmente enfrenta diz respeito à construção de um método confiável capaz de identificar se um determinado animal não humano possui estados mentais conscientes. A literatura nomeia essa questão de “o problema da mensuração da consciência animal”. A presente dissertação possui como objetivo analisar e responder esse problema através da (...) combinação entre o uso de evidências empíricas e de ferramentas filosóficas. Dito isso, existem inúmeras formas de respondê-lo. Ao longo do texto, analisarei algumas das que são consideradas mais relevantes na discussão atual. Uma delas é a concepção cética de que não há questão de fato sobre os animais não humanos serem ou não conscientes. Em contraste, as abordagens neutras e newtonianas buscam se esquivar de compromissos metafísicos e teóricos para atribuir consciência aos animais. Ao final da dissertação defenderei a chamada “abordagem teórica leve”, posição originalmente proposta pelo filósofo Jonathan Birch. Buscarei mostrar que ela é atualmente a hipótese empiricamente mais adequada e filosoficamente plausível dentre as disponíveis na literatura. (shrink)

Which animals have conscious experiences? Many different, diverse and unrelated behaviors and cognitive capacities have been proposed as tests of the presence of consciousness in an animal. It is unclear which of these tests, if any, are valid. To remedy this problem, I develop a list consisting of eight desiderata which can be used to assess putative tests of animal consciousness. These desiderata are based either on detailed analogies between consciousness-linked human behavior and non-human behavior, on theories of consciousness or (...) on methods from human consciousness science. If a test or set of tests satisfies more of these desiderata, passing it provides stronger evidence of consciousness. Moreover, one can design future tests of animal consciousness with the intention of satisfying these desiderata to ensure their evidential strength. (shrink)

As humans, we use the power of thinking to make scientific discoveries, develop technologies, manage social interactions, and transmit knowledge to the next generations. With the ability to think, we can trace back and discover the origin of the universe, the natural world, and ourselves. The content of this book, Mindsponge Theory, is part of that discovery process.

The monograph offers an original account of Spinoza’s philosophy and ethics concentrated on its concordance with selected modern neuroscientific theories. The book proceeds through the whole of Spinoza’s philosophy and by increasingly complex analytical account acquaints with its essential frameworks, terminology, and concepts, and is thus accessible also to readers who are not yet familiar with the thought of this peculiar thinker. The fundamental motives of this interpretation are the nature of the mind and the questions of human freedom and (...) human bondage, mainly in connection with the investigation of affects (passions and drives) that the mind tends to be bound with. In his philosophy, Spinoza not only offers brilliant analyses of human experience but in anticipation of modern psychotherapeutic techniques suggests practical methods for the realization of sufficiently functional affective-cognitive self-therapy aimed at the regulation and control of one’s passivity. The understanding of and working with one’s weaknesses is, according to Spinoza, the necessary condition for realizing one’s freedom, or – for being able to shift from pathetics to ethics. (shrink)

This thesis investigates the relationship between consciousness and self-consciousness. I consider two broad claims about this relationship: a constitutive claim, according to which all conscious experiences constitutively involve self-consciousness; and a typicalist claim, according to which ordinary conscious experiences contingently involve self-consciousness. Both of these claims call for elucidation of the relevant notions of consciousness and self-consciousness. -/- In the first part of the thesis ('The Myth of Constitutive Self-Consciousness'), I critically examine the constitutive claim. I start by offering an (...) elucidatory account of consciousness, and outlining a number of foundational claims that plausibly follow from it. I subsequently distinguish between two concepts of self-consciousness: consciousness of one's experience, and consciousness of oneself (as oneself). Each of these concepts yields a distinct variant of the constitutive claim. In turn, each resulting variant of the constitutive claim can be interpreted in two ways: on a 'minimal' or deflationary reading, they fall within the scope of foundational claims about consciousness, while on a 'strong' or inflationary reading, they point to determinate aspects of phenomenology that are not acknowledged by the foundational claims as being aspects of all conscious mental states. I argue that the deflationary readings of either variant of the constitutive claim are plausible and illuminating, but would ideally be formulated without using a term as polysemous as 'self-consciousness'; by contrast, the inflationary readings of either variant are not adequately supported. -/- In the second part of the thesis ('Self-Consciousness in the Real World'), I focus on the second concept of self-consciousness, or consciousness of oneself as oneself. Drawing upon empirical evidence, I defend a pluralist account of self-consciousness so construed, according to which there are several ways in which one can be conscious of oneself as oneself – through conscious thoughts, bodily experiences and perceptual experiences – that make distinct determinate contributions to one's phenomenology. This pluralist account provides us with the resources to vindicate the typicalist claim according to which consciousness of oneself as oneself – a sense of self – is pervasive in ordinary conscious experiences, as a matter of contingent empirical fact. It also provides us with the resources to assess the possibility that a subject might be conscious without being conscious of herself as herself in any way. (shrink)

One of the most important instances of distinct but inseparable entities is that of subject and object. When we carefully think about them, we realize that one term implies the other. In other words, a subject cannot possibly exist without a corresponding object otherwise we would never be able to talk about “subject.” In a similar way, an object can only be called an object because it is in relation to a subject. All opposites will in fact exhibit this same (...) interdependence when we carefully think about them. For example, we could not speak of “blindness” if there were no one who could see. The word “blind” would never have any reason for its existence unless someone had the ability to see. Light and darkness, sleep and waking, day and night, etc. all such terms have meaning only in relation to their opposition to one another. Thus we conclude that this opposition is essential to the existence of either term. We can look at existence as a polar reality or polarity. One side rises or falls with the other. There is no possible way that one side can exist without the other. (shrink)

The Western world has led the development of material science for over 200 years. But they have reached an impasse in confronting the problem of consciousness. Scientific knowledge requires a scientist, but regarding knowledge concerning the scientist, they must remain silent. India has always emphasized knowledge of the conscious self or atma. Vedanta-sutra begins with the aphorism “athatho brahma jijnasa” – now, therefore, inquire about brahma (pure consciousness). Even in the West, the Greek philosopher Socrates stated, “Above all else know (...) the self.” But since the time of Newton, the objective world became the focus of science to the exclusion of the conscious observer or scientist.

In the contemporary philosophy of mind and consciousness studies, views such as panpsychism or theories of universal consciousness (most notably I. Shani’s cosmopsychism and B. Kastrup’s cosmoidealism), have enjoyed a recent renaissance of metaphysical speculations in Western philosophy. Its similarities with Eastern philosophical traditions went not unnoticed. However, the potential contribution that the evolutionary cosmology of the Indian poet, mystic and philosopher Sri Aurobindo can offer to these ontologies, remains largely unknown or unexplored. Consciousness, mind, life, matter and evolution are (...) interpreted in an extended metaphysical framework, uniting Western and Eastern traditions inside a modern philosophical system where physicalism, panpsychism, cosmopsychism and philosophical idealism are not seen as irreconcilable exclusives, but different points of view that can be reconciled in a synthesis of knowledge, as envisioned from higher states of consciousness. This integral view of reality offers a conceptual platform that can complement and incorporate current theoretical approaches in the contemporary analytic philosophy, and naturally resolve some of their present internal inconsistencies.

One of the biggest problems in applications of animal welfare science is our ability to make comparisons between different individuals, particularly different species. Although welfare science provides methods for measuring the welfare of individual animals, there’s no established method for comparing measures between individuals. This problem occurs because of the underdetermination of the conclusions given the data, arising from two sources of variation that we cannot distinguish – variation in the underlying target variable (welfare experience) and in the relationship of (...) measured indicators to the target. In this paper I describe the similarity assumptions that underlie our current applications of interspecies comparisons and examine in which cases they are justified, as well as describing alternative methods we may use when they are not. In the end, all our available options for making interspecies comparisons are imperfect, and we need to make explicit context-specific decisions about which will be best for the task at hand while acknowledging their potential limitations. Future developments in our understanding of the biology of sentience will help strengthen our methods of making welfare comparisons. (shrink)

The Integrated Information Theory (IIT) formulated for the first time in 2004 by the neuroscientist Giulio Tononi, is a theoretical framework aiming to scientifically explain phenomenal consciousness. The IIT is presented in the first part of this work. Broadly speaking, integrated information is an abstract quantitative measure of the causal power a system has on itself. The main claim of IIT is the identity between informational structures and experience. The nature of this identity will be the subject of the second (...) part. One can interpret the IIT as a fundamental law of nature connecting the physical domain to the mental domain. The philosophical implications of such a claim are numerous and they are subject to criticism. This will be the main concern of the third and last part. (shrink)

Is it possible to build a conscious machine, an artifact that has qualitative experiences such as feeling pain, seeing the redness of a flower or enjoying the taste of coffee ? What makes such experiences conscious is their phenomenal character: it is like something to have such experiences. In contemporary philosophy of mind, the question of the qualitative aspect of conscious experiences is often addressed in terms of qualia. In a pre-theoretical and intuitive sense, qualia refer to the phenomenal character (...) or “what-it’s-like-ness” of a conscious experience: the painfulness of a pain experience or the redness of a visual experience of a red object. The problem of artificial qualia is the question of the theoretical possibility of the realization of qualia by artifacts. In this work, this problem will serve as a methodological tool to address what is arguably the most fundamental question of philosophy of mind: what exactly is consciousness? (shrink)

I start by defining sentience and giving an analysis of the epistemological problems that plague its scientific study; this consists mainly in justifying that the attribution of sentience is underdetermined by the data. Second I show that as a result of this situation of underdetermination, most of the types of arguments used to infer sentience from the data are inconclusive and lead to a stalemate. Third, I argue that the stalemates arise from a foundationalist epistemology which needlessly leads to skeptical (...) conclusions; as an alternative, I propose to adopt a coherentist framework and defend a process of ‘epistemic iteration’ (Chang 2004) within that framework, which I argue gives us a way out of the underdetermination.

In the philosophy of mind, the causal relationship between phenomenal consciousness, mentation and brain states has always been a matter of debate. On the one hand, material monism posits consciousness and mind as pure brain-epiphenomena. One of its most stringent lines of reasoning relies on the premise that because a cerebral impairment, or its anatomical and biochemical modification, leads to a cognitive impairment and/or altered states of consciousness, there is no reason to doubt the mind-brain identity. On the other hand, (...) dualism or idealism (in one form or another) regard consciousness and mind as something other than the sole product of cerebral activity pointing at the ineffable and undefinable seemingly unphysical nature of our subjective qualitative experience and its related mental dimension. Here, we argue that the premise of material monism is based on a logical correlation-causation fallacy and will review some neuroscientific and biological findings that question the idea that posits phenomenal experience as an emergent property of brain activity. While these (mostly ignored) findings, if considered separately from each other, could, in principle, be recast into a physicalist paradigm, once viewed from an integral perspective, they substantiate equally well, if not even more effectively, an ontology that posits mind and consciousness as a primal phenomenon.

Anil Gupta’s Conscious Experience: A Logical Inquiry provides an impressive and novel account of rational justification based on conscious experience which is used as a foundation for a new theory of empiricism. In this critical notice, I argue that Gupta’s project is fascinating, but is often hampered by a lack of sufficient philosophical justification and clarity regarding some essential features of his project, as well as a lack of engagement with relevant scientific domains that would directly bear on it, such (...) as computational neuroscience, cognitive neuroscience, and cognitive psychology. This limits the sort of logical inquiry available to him in problematic ways. (shrink)

Perceptual filling-in for vision is the insertion of visual properties (e.g., color, contour, luminance, or motion) into one’s visual field, when those properties have no corresponding retinal input. This paper introduces and provides preliminary empirical support for filled/non-filled pairs, pairs of images that appear identical, yet differ by amount of filling-in. It is argued that such image pairs are important to the experimental testing of theories of consciousness. We review recent experimental research and conclude that filling-in involves brain activity with (...) relatively high integrated information (Phi) compared to veridical visual perceptions. We then present filled/non-filled pairs as an empirical challenge to the integrated information theory of consciousness, which predicts that phenomenologically identical experiences depend on brain processes with identical Phi.

The science of mind wandering has rapidly expanded over the past 20 years. During this boom, mind wandering researchers have relied on self-report methods, where participants rate whether their minds were wandering. This is not an historical quirk. Rather, we argue that self-report is indispensable for researchers who study passive phenomena like mind wandering. We consider purportedly “objective” methods that measure mind wandering with eye tracking and machine learning. These measures are validated in terms of how well they predict self-reports, (...) which means that purportedly objective measures of mind wandering retain a subjective core. Mind wandering science cannot break from the cycle of self-report. Skeptics about self-report might conclude that mind wandering science has methodological foundations of sand. We take a rather more optimistic view. We present empirical and philosophical reasons to be confident in self-reports about mind wandering. Empirically, these self-reports are remarkably consistent in their contents and behavioral and neural correlates. Philosophically, self-reports are consistent with our best theories about the function of mind wandering. We argue that this triangulation gives us reason to trust both theory and method. (shrink)

To describe computers and sophisticated robots, many people today have no problem using personal attributes. Alan Turing published his famous intelligence test in 1950. From that time onwards, computers have gained increasingly higher status in this regard. Computers and robots nowadays are not only intelligent. They perceive, they remember, they understand, they decide, they play and so on. Recently, another such step has occurred but, this time, many researchers are seriously concerned. In February 2017, the European Parliament passed a Resolution (...) to attribute legal personhood to intelligent robots. If this is accepted as law, it will have very serious consequences for our self-understanding and for the way we live together as a community. The EU Resolution has stimulated various studies, arising mainly from the area of legal studies. It is urgent that the response include also a philosophical evaluation regarding the fundamental concepts at play. This paper seeks to make a contribution precisely in this area. It explores the attribution of legal personhood to machines by focusing on what is happening at the level of meaning. It explores crucial concepts like responsibility, autonomy, person and quasi-person by drawing inspiration from the seminal works of Aristotle and L. Wittgenstein and from the ensuing debates between current philosophers like P. Hacker and D. Dennett. The results of this paper indicate what dangers could lie ahead and what could be the right way to avoid them. (shrink)

Despite their popularity, relatively scant attention has been paid to the upshot of Bayesian and predictive processing models of cognition for views of overall cognitive architecture. Many of these models are hierarchical ; they posit generative models at multiple distinct "levels," whose job is to predict the consequences of sensory input at lower levels. I articulate one possible position that could be implied by these models, namely, that there is a continuous hierarchy of perception, cognition, and action control comprising levels (...) of generative models. I argue that this view is not entailed by a general Bayesian/predictive processing outlook. Bayesian approaches are compatible with distinct formats of mental representation. Focusing on Bayesian approaches to motor control, I argue that the junctures between different types of mental representation are places where the transitivity of hierarchical prediction may be broken, and I consider the upshot of this conclusion for broader discussions of cognitive architecture.

Peter Carruthers has recently argued for a surprising conditional: if a global workspace theory of phenomenal consciousness is both correct and fully reductive, then there are no substantive facts to discover about phenomenal consciousness in nonhuman animals. I present two problems for this conditional. First, it rests on an odd double-standard about the ordinary concept of phenomenal consciousness: its intuitive non-gradability is taken to be unchallengeable by future scientific developments, whereas its intuitive determinacy is predicted to fall by the wayside. (...) Second, it relies on dismissing, prematurely, the live empirical possibility that phenomenal consciousness may be linked to a core global broadcast mechanism that is shared by a wide range of animals. Future developments in the science of consciousness may lead us to reconsider the non-gradability of phenomenal consciousness, but they are unlikely to lead us to accept that there are no facts to discover outside the paradigm case of a healthy adult human.

In his book “Galileo’s Error”, Philip Goff lays out what he calls “foundations for a new science of consciousness”, which are decidedly anti-physicalist (panpsychist), motivated by a critique of Galileo’s distinction into knowable objective and unknowable subjective properties and Arthur Eddington’s argument for the limitation of purely structural (physical) knowledge. Here we outline an alternative theory, premised on the Interface Theory of Perception, that too subscribes to a “post-Galilean” research programme. However, interface theorists disagree along several lines. 1. They note (...) that Galileo’s distinction should be replaced by a truly non-dual account, referring to a difference of degree only. 2. They highly appreciate the role of mathematics, in particular when it comes to actually engage scientifically with consciousness. Some notable features of the interface theory are its skepticism towards our epistemic capacities and its rejection of the existence of a public, mind-independent reality. In addition, some interface theorists further employ a thin concept of “conscious agency” to ground their theory. The interface theory leaves open many of the problems of consciousness science (e.g. what is a “self”?) as questions for further (scientific, mathematical) research. (shrink)

In Galileo's Error, Philip Goff sets out a manifesto for a post-Galilean science of consciousness. Article four of the manifesto reads: 'Anti-Dualism: Consciousness is not separate from the physical world; rather consciousness is located in the intrinsic nature of the physical world.' I argue that there is an important sense of ‘dualism’ in which Goff’s arguments are not only compatible with but entail dualism, and not only dualism but substance dualism. Substance dualism, in the sense I have in mind, is (...) the view that (i) there are two sides to reality, a fundamentally mental side and a fundamentally nonmental side; and (ii) the fundamentally mental side consists of mental substances resembling Cartesian souls. I do not suggest that this is bad news for post-Galilean science of consciousness. My aim is rather to push for a certain view about what a theory of consciousness motivated by Goff’s arguments must look like. (shrink)

The question of what happens when we die may just be the most intriguing of them all. Unfortunately, I am not a ghost, and could not tell you what definitely occurs when we sink our lungs in and close our eyes for the last time. However, one can speculate. If the theories of reincarnation, Heaven and Hell, or void of nothingness fail to convince you, surely there are more possibilities to contemplate - especially ones that focus on experiencing the afterlife (...) through your consciousness.

Brief review of Mark Solms' "The Hidden Spring: A Journey to the Source of Consciousness".

First-person reports of Major Depressive Disorder reveal that when an individual becomes depressed a profound change or ‘shift’ to one’s conscious experience occurs. The depressed person reports that something fundamental to their experience has been disturbed or shifted; a change associated with the common but elusive claim that when depressed one finds oneself in a ‘different world’ detached from reality and other people. Existing attempts to utilise these phenomenological observations in a psychiatric context are challenged by the fact that this (...) experiential ‘shift’ characteristic of depression appears mysterious and resists analysis in scientific terms. This paper offers a way out of this predicament. The hypothesis proposed is that when an individual becomes depressed, the individual departs from a state of ordinary wakeful consciousness and enters a distinctive global state of consciousness akin to dreaming and the psychedelic state. After unpacking and motivating this hypothesis in the context of research in consciousness science, I outline two of its important implications for the neurobiology of depression and psychedelic psychiatry. The upshot is a promising and conceptually well-motivated hypothesis about depression which is apt for empirical uptake and development. (shrink)

Coronary arteries were studied on 110 postmortem human hearts during January 2000 to December 2001 in the department of Anatomy and Microbiology, Bangladesh Medical College to observed. The pattern of coronary dominance and its relation with atherosclerosis was observed. Atherosclerosis was found in 49(44.5%) samples, among which 37(56.%) were from male and 12(26.7%) from female hearts. This difference was significant (P<0.01). Right dominance was observed in 72 (65.5%) cases while 17 (15.5%) had left dominance and 21 (19.1%) had balanced type (...) of circulation. Balanced type of circulation was observed more among females (14; 66.7%) while left dominance was more frequent among males (13; 76.5 %). This deference on the basis of sex was significant (P<0.05). Significant (P<0.001) relationship was also observed between atherosclerosis and dominance of coronary artery. It may be concluded that atherosclerosis was present in almost half of the studied subjects and was found more among males. Left dominance was more frequently present among males it was associated with atherosclerosis. (shrink)

In passing remarks, some commentators have noted that for Nagel, physicalism is true. It has even been argued that Nagel seeks to find the best path to follow to achieve future physicalism. I advance these observations by adding that for Nagel, we should discuss the consciousness problem not in terms of physical and mental issues but in terms of our desire to include consciousness in an objective/scientific account, and we can achieve this only by revising our self-conception, i.e., folk psychology, (...) to develop a more detached view of experience. Through the project of objective phenomenology, Nagel aims to achieve some sort of objective, detached, and scientific explanation of the subjective nature of experience. This project seeks to make the truth of physicalism intelligible and consciousness more amenable to scientific study, potentially raising an even broader concept than the one physicalism originally proposes.

Abstract to Equations, Qualia, and Qualations -/- With regard to consciousness, we could write an equation B = black. But it is possible to rewrite this using a quale, namely, B = █. This latter equation might be called a ‘qualation’. It has the same meaning regardless of the physiology that apprehends it. This article argues a whole theory of qualations could be developed. Further, to a Dualist, it could be that a materialist is convinced by materialist arguments involving the (...) first equation, but it is unimaginable how this could ever be for a qualation. In view of the strong association of qualia with McTaggart’s A-series (future/present/past) a few notes on time are included. (shrink)

This paper explores the problematic issue of the theoretical dominance of neuroscience in the discipline of consciousness studies and tries to explain why such a dominance must not be encouraged through the philosophical and logical divulgement of the methodological shortcomings of neuroscience in explaining consciousness. Besides this, the paper also reminds us of the utmost and exclusive importance of 'consciousness' in consciousness studies and rivets our attention to the immense importance of adopting a multidisciplinary ecumenic approach towards understanding consciousness.

Doerig et al. have set several criteria that theories of consciousness need to fulfill. By these criteria, higher-order theories fare better than most existing theories. But they also argue that higher-order theories may not be able to answer both the ‘small network argument’ and the ‘other systems argument’. In response, we focus on the case of the Perceptual Reality Monitoring theory to explain why higher-order theories do just fine.

“Pick a card, any card. This has to be a completely free choice.” the magician tells you. But is it really? Although we like to think that we are using our free will to make our decisions, research in psychology has shown that many of our behaviours are automatic and unconsciously influenced by external stimuli (Ariely, 2008; Bargh & Chartrand, 1999; Newell & Shanks, 2014; Nisbett & Wilson, 1977), and that we are often oblivious to the cognitive mechanisms that underpin (...) our decision (Wegner, 2002, 2003). Magicians have exploited this illusory sense of agency for a long time, and have developed a wide range of techniques to influence and control spectators’ choices of such things as card, word, or number (Annemann, 1933; Banachek, 2002a; Jones, 1994; Turner, 2015). These techniques are instances of what is called forcing. -/- Many forces are extremely effective, illustrating various weaknesses in our sense of control over decisions and their outcomes. Researchers have started to investigate them in various ways (Kuhn, Pailh s, & Lan, 2020; Olson, Amlani, Raz, & Rensink, 2015; Pailhes & Kuhn, 2020b, 2020c; Shalom et al., 2013) and are beginning to obtain valuable insights into decision-making processes as well as a better understanding of the cognitive mechanisms that lead people to experience an illusory sense of free will and of agency. -/- Although magicians have acquired large amounts of knowledge in covertly controlling people’s choices, much of this knowledge is only discussed in the context of individual magic tricks, or in books that are not readily accessible to non-magicans. As we and others have argued elsewhere (Ekroll, Sayim, & Wagemans, 2017; Kuhn, 2019; Kuhn, Amlani, & Rensink, 2008; Kuhn, Caffaratti, Teszka, & Rensink, 2014; Macknik et al., 2008; Olson et al., 2015; Olson, Landry, Appourchaux, & Raz, 2016; Shalom et al., 2013; Thomas, Didierjean, Maquestiaux, & Gygax, 2015), a particularly effective way of making this knowledge more available is via the creation of taxonomies centered around psychological mechanisms (Rensink & Kuhn, 2015). For example, the psychologically based taxonomy of misdirection (Kuhn et al., 2014) helps draw links between misdirection and formal theories of perception and cognition. -/- Our aim here is to apply a similar process to the knowledge magicians have about forcing. The present paper develops a psychologically based taxonomy of forcing techniques with two goals in mind. Firstly, it should help uncover the various psychological mechanisms that underlie forcing techniques. Secondly, it should facilitate knowledge transfer between magicians and psychologists. Among other things, this knowledge will allow researchers to gain new insights into the mechanisms underlying decision-making, and the feeling of free will and of agency over choice. We start by defining the magician’s force and then look at some of the past classifications of forcing. (shrink)

This paper is about whether consciousness flows. Evan Thompson (2014) has recently claimed that the study of binocular rivalry shows that there are some moments where consciousness does not flow, contra William James (1890). Moreover, he’s claimed that Abhidharma philosophers reject James’s claim that consciousness flows. I argue that binocular rivalry poses no special challenge to James. Second, I argue that because Thompson did not take up the question of how James and Abhidharma philosophers analyse or define flow, he under-described (...) their disagreement in a way that obscures an important conceptual contribution that Abhidharma philosophers make to the study of flow. They reject James’s claim that there are only two conceivable ways for consciousness to fail to flow, and suggest that there is a third way for consciousness to fail to flow – a way that James’s imagination did not reveal to be possible.

Peter Carruthers argues that the global workspace theory implies there are no facts of the matter about animal consciousness. The argument is easily extended to other cognitive theories of consciousness, posing a general problem for consciousness studies. But the argument proves too much, for it also implies that there are no facts of the matter about human consciousness. A key assumption of the argument is that scientific theories of consciousness must explain away the explanatory gap. I criticize this assumption and (...) point to an alternative strategy for defending scientific theories of consciousness, one that better reflects the ongoing scientific practice. I argue there are introspectable inferential connections from phenomenal concepts to functional concepts that scientists can use to individuate the global workspace in terms of capacities that animals and humans share.

We welcome Mikhalevich & Powell’s (2020) (M&P) call for a more “‘inclusive”’ animal ethics, but we think their proposed shift toward a moral framework that privileges false positives over false negatives will require radically revising the paradigm assumption in animal research: that there is a clear line to be drawn between sentient beings that are part of our moral community and nonsentient beings that are not.

The problem of free will is associated with a specific and significant kind of control over our actions, which is understood primarily in the sense that we have the freedom to do otherwise or the capacity for self‐determination. Is Buddhism compatible with such a conception of free will? The aim of this article is to address three critical issues concerning the free will problem: (1) what role should accounts of physical and neurobiological processes play in discussions of free will? (2) (...) Is a conception of mental autonomy grounded in practices of meditative cultivation compatible with the three cardinal Buddhist doctrines of momentariness, dependent arising, and no‐self? (3) Are there enough resources in Buddhism, given its antisubstantialist metaphysics, to account for personal agency, self‐control, and moral responsibility? (shrink)

Approximation involves representing things in ways that might be close to the truth but are nevertheless false. Given the widespread reliance on approximations in science and everyday life, here we ask whether it is conceptually possible for false approximations to qualify as knowledge. According to the factivity account, it is impossible to know false approximations, because knowledge requires truth. According to the representational adequacy account, it is possible to know false approximations, if they are close enough to the truth for (...) present purposes. In this paper, we adopt an experimental methodology to begin testing these two theories. When an agent provides a false and practically inadequate answer, both theories predict that people will deny knowledge. But the theories disagree about an agent who provides a false but practically adequate answer: the factivity hypothesis again predicts knowledge denial, whereas the representational adequacy hypothesis predicts knowledge attribution. Across two experiments, our principal finding was that people tended to attribute knowledge for false but practically adequate answers, which supports the representational adequacy account. We propose an interpretation of existing findings that preserves a conceptual link between knowledge and truth. According to this proposal, truth is not necessary for knowledge, but it is a feature of prototypical knowledge. (shrink)

Conscious experiences are characterized by mental qualities, such as those involved in seeing red, feeling pain, or smelling cinnamon. The standard framework for modeling mental qualities represents them via points in geometrical spaces, where distances between points inversely correspond to degrees of phenomenal similarity. This paper argues that the standard framework is structurally inadequate and develops a new framework that is more powerful and flexible. The core problem for the standard framework is that it cannot capture precision structure: for example, (...) consider the phenomenal contrast between seeing an object as crimson in foveal vision versus merely as red in peripheral vision. The solution I favor is to model mental qualities using regions, rather than points. I explain how this seemingly simple formal innovation not only provides a natural way of modeling precision, but also yields a variety of further theoretical fruits: it enables us to formulate novel hypotheses about the space and structures of mental qualities, formally differentiate two dimensions of phenomenal similarity, generate a quantitative model of the phenomenal sorites, and define a measure of discriminatory grain. A noteworthy consequence is that the structure of the mental qualities of conscious experiences is fundamentally different from the structure of the perceptible qualities of external objects.

This article reports on Clean Language Interviewing (CLI), a rigorous, recently developed 'content-empty' (non-leading) approach to second-person interviewing in the science of consciousness. Also presented is a new systematic third-person method of validation that evaluates the questions and other verbal interventions by the interviewer to produce an adherence-to-method or 'cleanness' rating. A review of 19 interviews from five research studies provides a benchmark for interviewers seeking to minimize leading questions. The inter-rater reliability analysis demonstrates substantial agreement among raters with an (...) average intraclass correlation coefficient of 0.72 (95% CI). We propose that this method of validation is applicable not only to CLI but to second-person interviews more generally. (shrink)

Memories are mental states with a number of interesting features. One of those features seems to be their having an intentional object. After all, we commonly say that memories are about things, and that a subject represents the world in a certain way by virtue of remembering something. It is unclear, however, what sorts of entities constitute the intentional objects of memory. In particular, it is not clear whether those are mind-independent entities in the world or whether they are mental (...) entities of some kind. The purpose of this chapter is to map the different positions on this issue, and to highlight the virtues and difficulties for each of the options. In Section 2, I will specify the question of what the intentional objects of memory are by clarifying the relevant notions of memory and intentional object. In Section 3, I will motivate the significance of identifying the intentional objects of memory by exploring the relations between, on the one hand, the intentionality of memory and, on the other hand, the phenomenology and the epistemology of memory. In Section 4, I will consider two natural candidates for being the intentional objects of memory, namely, worldly entities and mental entities, and I will raise some concerns for each of the two candidates. A promising alternative will emerge, in Section 5, as preserving the virtues of the two original candidates while avoiding their difficulties. The alternative will concern a certain combination of worldly and mental entities; a combination that involves both causal and truth-making relations. I will conclude by sketching how the alternative candidate can shed some light on the phenomenological and epistemological issues raised in the third section. (shrink)

Although vision is the de facto model system of consciousness research, studying olfactory consciousness has its own advantages, as this collection of articles emphatically demonstrates. One advantage of olfaction is its computational and phenomenological simplicity, which facilitates the identification of basic principles. Other researchers study olfactory consciousness not because of its simplicity, but because of its unique features. Together, olfaction's simplicity and its distinctiveness make it an ideal system for testing theories of consciousness. In this research topic, the results of (...) recent research into olfactory consciousness are presented. (shrink)

We humans have a formidable armamentarium of social display behaviours, including song-and-dance, the visual arts, and role-play. Of these, role-play is probably the crucial adaptation which makes us most different from other apes. Human childhood, a sheltered period of ‘extended irresponsibility’, allows us to develop our powers of make-believe and role-play, prerequisites for human cooperation, culture, and reflective consciousness. Social mirror theory, originating with Dilthey, Baldwin, Cooley and Mead, holds that there cannot be mirrors in the mind without mirrors in (...) society. I will present evidence from the social and behavioural sciences to argue that self-awareness depends on social mirrors and shared experiential worlds. The dependence of reflectivity on shared experience requires some reframing of the ‘hard problem’, and suggests a non-trivial answer to the zombie question. (shrink)

In 1998 I asked my friend Tjiniman, who is a stone-age hunter, to give us his non-western perspective on ‘Tucson III’ (Murinbata&Whitehead, 1998).Most people thought I just made Tjiniman up and the whole thing was intended as a joke, and he has spent the last two years worrying about this. Since then he has gained a modest BSc in Social Anthropology, though in my view the examiners failed to appreciate some of his less obvious insights, and he deserved a higher (...) mark. He now has a better understanding of us white people and our ways, and this is his second attempt to make us see the truth. He did ask me to edit his text and take out anything that white people might mistake for a joke, but in many cases he accused me of cutting the best bits and made me put them back in. I had to add the notes and references because Tjiniman thinks all ideas come from the ancestors and no one should claim credit for them — CW. (shrink)

The contents of our conscious mind can seem unpredictable, whimsical, and free from external control. When instructed to attend to a stimulus in a work setting, for example, one might find oneself thinking about household chores. Conscious content thus appears different in nature from reflex action. Under the appropriate conditions, reflexes occur predictably, reliably, and via external control. Despite these intuitions, theorists have proposed that, under certain conditions, conscious content resembles reflexes and arises reliably via external control. We introduce the (...) Reflexive Imagery Task, a paradigm in which, as a function of external control, conscious content is triggered reliably and unintentionally: When instructed to not subvocalize the name of a stimulus object, participants reliably failed to suppress the set-related imagery. This stimulus-elicited content is considered ‘high-level’ content and, in terms of stages of processing, occurs late in the processing stream. We discuss the implications of this paradigm for consciousness research. (shrink)

Do you think the quotation in my title is reasonable or unreasonable? I find it unreasonable, but I know that many will not. Two people can react to the same idea, opinion, or data in opposite ways, and the reasons for this are often ideological. Ideology always has a political origin — in this case perhaps reflecting turf wars, career promotion, self-legitimation, the privileged status of science in post-industrial societies, and the need to say the right things in order to (...) get research funding. The very concept of ‘hard science’ is ideological, implying that one part of our experience is ‘objective’ (meaning that it confers authority on scientists) and the other part is ‘subjective’(meaning that the opinions of non-scientists are of little worth).What we call ‘objective’ is of course a mental model built on the basis of experiences which we call ‘subjective’. There are many possible ways of carving up experience, but none that leads to a useful or non-political distinction between ‘objective’ and ‘subjective’. (shrink)

I find it hard to say whether TSC this year was the most balanced or the most biased since the first I attended in 1998. That year there were 35 plenary talks, of which 27 were distinctly materialist — that is, they assumed that consciousness ‘arises’ from ‘physical’ processes in the brain. This year there were also 35 plenaries, with 24 devoted to physicalist accounts. I cannot claim absolute precision for these figures, because it is not always easy to make (...) black-and-white distinctions. Research by Imants Barušs (2008) has shown that many scientists have non-physicalist beliefs but do not say so for fear of jeopardising their careers. In that case they may present apparently physicalist papers although physicalist assumptions are not present. (shrink)

Representationalism, in its most widely accepted form, is the view that the human mind is an information-using system, and that human cognitive capacities are to be understood as representational capacities. This chapter distinguishes several distinct theses that go by the name "representationalism," focusing on the view that is most prevalent in cogntive science. It also discusses some objections to the view and attempts to clarify the role that representational content plays in cognitive models that make use of the notion of (...) representation. (shrink)

In their article “Out of nowhere: thought insertion, ownership and context-integration”, Jean-Remy Martin & Elisabeth Pacherie criticize the standard approach to thought insertion. However, their criticism is based on a misunderstanding of what the standard approach actually claims. By clarifying the notions ‘sense of ownership’ and ‘sense of agency’, I show that Martin & Pacherie’s own approach can be construed as a refined version of the standard approach.

I am proposing a new Copernican revolution, that Consciousness and not matter is the true basis of the universe. Here is an account of my graduate student days at the Rockefeller University as a woman pioneer in science, and a sense of what I am really about in all of my works. I am giving a woman's take on the universe.
