Science of Consciousness, Misc

The ability to anticipate events, to foresight, is an adaptive advantage. We humans use it all the time. Animals have a limited access to it. Positioning foresight in human evolution is a complex subject (Suddendorf, 2013). Why and how are humans, and not chimpanzees, performant in anticipating events? We propose here to address that question with an evolutionary scenario that links self-consciousness to anxiety management (Menant, 2018). The scenario positions self-consciousness as “the capability to represent one’s own entity as existing (...) in the environment, like conspecifics are represented as existing” (making “thinking about oneself” possible). The scenario proposes that our pre-human ancestors were capable of some level of identifications with their conspecifics, and that its development has progressively brought our ancestors to represent themselves as existing in the environment like their conspecifics were represented, thus introducing self-consciousness. The scenario also proposes that identifications with suffering conspecifics have been the source of an important anxiety that had to be limited for evolution to continue. Some of our ancestors have not been able to limit that new anxiety. Their mental pain became unbearable. Their evolution was almost stopped, thus initiating the pan-homo split. Developing an ability to anticipate events has been a key contributor to anxiety limitation by providing information about the sufferings to come, and consequently allowing to limit and avoid them. In addition to that role of foresight in human evolution it is worth noticing that the associated chaining of mental events brings to propose foresight as an entry point to the concept of causality in human evolution. Regarding our chimpanzee cousins, the pan-homo split in the scenario positions them as not self-conscious, not capable of anticipation like humans are, and less anxious than humans. Continuations are proposed. (shrink)

I outline and develop a particular physicalist perspective on qualia, and suggest that it may be the basis of a correct account of the relationship of mental states to the physical world. Assume that a quale is a perspective on a physical state in the organism – the reality as known as distinct from the reality as such – but that the perspective, though it entails irreducible experiential knowledge, has no physical substance over that encompassed in the physical state itself. (...) Assume this physical state is also a brain state. The position is a useful one. First, reductionist physicalism is true, but experiential qualities are irreducible physical knowledge, and a required part of our physical world view. Second, experiences are not additional problems over those addressed externally, but only how these problems seem when known internally – an experience just is the physical state that underlies its external counterpart, and the same standard scientific account suffices to explain both, permitting a science of consciousness to develop by applying the same standard external–observer–based methods adopted in older scientific disciplines. Finally, challenges to physicalism associated with the ‘unbridgeable gap’, Leibniz's Law, Jackson's knowledge argument, and Chalmers' hard problem of consciousness are successfully countered.

It would be unwise to dismiss the possibility of human brain organoids developing sentience. However, scepticism about this idea is appropriate when considering current organoids. It is a point of consensus that a brainstem-dead human is not sentient, and current organoids lack a functioning brainstem. There are nonetheless troubling early warning signs, suggesting organoid research may create forms of sentience in the near future. To err on the side of caution, researchers with very different views about the neural basis of (...) sentience should unite behind the “brainstem rule”: if a neural organoid develops or innervates a functioning brainstem that registers and prioritizes its needs, regulates arousal, and leads to sleep-wake cycles, then it is a sentience candidate. If organoid research leads to the creation of sentience candidates, a moratorium or indefinite ban on the creation of the relevant type of organoid may be appropriate. A different way forward, more consistent with existing approaches to animal research, would be to require ethical review and harm-benefit analysis for all research on sentience candidates. (shrink)

This is a model of consciousness. The hard problem of consciousness, what it feels like, is answered. The work builds on medical research analyzing the source and mechanisms associated with our feelings. It goes further by describing a generic model with wide applicability. The model is fully consistent with medical pathways in humans, but easily extends to animals and AI. The essence of the model is the interplay between associative memory and physiology. The model is a clear and concrete counterexample (...) to the famous philosophical objections to a scientific explanation. (shrink)

Phenomenal consciousness appears to be particularly normatively significant. For this reason, sentience-based conceptions of ethics are widespread. In the field of animal ethics, knowing which animals are sentient appears to be essential to decide the moral status of these animals. I argue that, given that materialism is true of the mind, phenomenal consciousness is probably not particularly normatively significant. We should face up to this probable insignificance of phenomenal consciousness and move towards an ethic without sentience.

An emerging body of research suggests that psychedelic experiences can change users’ religious or metaphysical beliefs. Here I explore issues concerning psychedelic-induced belief change via a critique of some recent arguments by Wayne Glausser. Two scientific studies seem to show that psychedelic experiences can convert atheists to belief in God, but Glausser holds that academic and popular discussions of these studies are misleading. I offer a different analysis of the relevant findings, attempting to preserve the insights of Glausser’s critique while (...) setting the record straight on some important points. For one thing, the studies provide stronger evidence for atheist deconversion than Glausser allows. For another, Glausser’s arguments against the “Metaphysical Belief Theory” of psychedelic therapy involve scientifically dubious claims and inferences. Finally, in evaluating this theory, we ought to focus on its strongest version, which posits belief shifts from metaphysical naturalism to non-naturalism, rather than from atheism to classical monotheism.

Psychedelic ingestion and meditative practice are both ancient methods for altering consciousness that became widely known in Western society in the second half of the 20th century. Do the similarities begin and end there, or do these methods – as many have claimed over the years – share some deeper common elements? In this chapter I take a neurophilosophical approach to this question and argue that there are, indeed, deeper commonalities. Recent empirical studies show that psychedelics and meditation modulate overlapping (...) brain networks involved in the sense of self, salience, and attention; moreover, psychedelics can occasion lasting increases in “mindfulness-related capacities” for taking a non-reactive stance on one’s inner experience (e.g. Sampedro et al. 2017). The self-binding theory of psychedelic ego dissolution (Letheby and Gerrans 2017) offers a plausible explanation of these findings: by disrupting self-related beliefs implemented in high-level cortical networks, both psychedelics and meditation can “unbind” mental contents from one’s self-model, moving these contents along the continuum from phenomenal transparency to opacity (cf. Metzinger 2003). In other words, both psychedelics and meditation can expose and weaken our foundational beliefs about our own identity, allowing us to disidentify with these beliefs and see them as “just thoughts”. There are connections between these ideas and recent arguments suggesting that psychedelic use may have epistemic benefits consistent with philosophical naturalism (Letheby 2015, 2016, 2019). I conclude with a proposal: these connections may help in thinking about the putative epistemic benefits of meditation practice from a naturalistic perspective. (shrink)

Mind, Consciousness and Body -/- We do not know how to think with or about these notions and others such as reality, perception, space, time, etc… In the following I will deal with the umbrella notions of mind, consciousness and body. The contents is relevant, but of greater importance is the manner or method in which I deal with these notions. I first present as an illustration of my approach or method, how I have dealt with the notions of intuition (...) and intuiting. One of the points I am trying to make is that: we do not know how to think about many things, for example mind, consciousness, awareness, body, intuition, etc. Therefore, I attempt to explore a number of things that we must investigate and deal with before we use these and other notions, as if they are clearly defined terms, before we try to use them to think and to think about anything, especially many leveled and multi- dimensional issues and problems such as the workings of ‘the mind, the body, intuition, consciousness and the relationship, if there are any, between these and other things. Then I suggest the initial steps for a few very basic requirements before the exploration of a theory of embodied, living, conscious tissues and a model for embodied (self-) consciousness research.

In the past two decades a number of arguments have been given in favor of the possibility of phenomenal consciousness without attentional access, otherwise known as phenomenal overflow. This paper will show that the empirical data commonly cited in support of this thesis is, at best, ambiguous between two equally plausible interpretations, one of which does not posit phenomenology beyond attention. Next, after citing evidence for the feature-integration theory of attention, this paper will give an account of the relationship between (...) consciousness and attention that accounts for both the empirical data and our phenomenological intuitions without positing phenomenal consciousness beyond attention. Having undercut the motivations for accepting phenomenal overflow along with having given reasons to think that phenomenal overflow does not occur, I end with the tentative conclusion that attention is a necessary condition for phenomenal consciousness. -/- .

My aim in this paper is to critically evaluate the debate surrounding the distinction between phenomenal and representational character of conscious experience which is one of the important debates in contemporary philosophy of mind and consciousness studies. The main objective of this paper is to seek an answer to the question- whether the content of conscious experience is phenomenal or intentional, or both? In the introduction, I will introduce the phenomenal and representational as two significant properties of consciousness. In the (...) first part, I will articulate the debate regarding the distinction between phenomenal and representational character of consciousness. Here I will argue that the phenomenal and representational properties of experience are not mutually exclusive of each other as many philosophers have taken them to be and one can be understood in relation to the other. In relation to the above distinction, many theories of consciousness have been developed emphasizing on the one or the other property of consciousness. My second objective in this paper is to argue against the strong or reductive representationalism. In relation to this, I will discuss Michael Tye’s position as a representative of strong representationalism. In the third part, I will argue against it drawing sources from the works of various non-reductive representationalists particularly from Tim Crane’s version of representationalism. In the final section, I will try to defend a position which may be called phenomenological representationalism where I will try to reconcile the divide between phenomenology and intentionality. In this context, I will argue, on the one hand, against the Cartesian notion of subjectivity which leads to pure phenomenal consciousness and, on the other hand, against the physical explanation of consciousness which leads to strong representationalism.

This third paper locates the synthetic neurorobotics research reviewed in the second paper in terms of themes introduced in the first paper. It begins with biological non-reductionism as understood by Searle. It emphasizes the role of synthetic neurorobotics studies in accessing the dynamic structure essential to consciousness with a focus on system criticality and self, develops a distinction between simulated and formal consciousness based on this emphasis, reviews Tani and colleagues' work in light of this distinction, and ends by forecasting (...) the increasing importance of synthetic neurorobotics studies for cognitive science and philosophy of mind going forward, finally in regards to most- and myth-consciousness.

Contemporary studies in unconscious cognition are essentially founded on dissociation, i.e., on how it dissociates with respect to conscious mental processes and representations. This is claimed to be in so many and diverse ways that one is often lost in dissociation. In order to reduce this state of confusion we here carry out two major tasks: based on the central distinction between cognitive processes and representations, we identify and isolate the main dissociation paradigms; we then critically analyze their key tenets (...) and reported findings.

Introspective and phenomenological methods are once again being used to support the use of subjective reports, rather than objective behavioural measures, to investigate and measure consciousness. Objective measures are often seen as useful ways of investigating the range of capacities subjects have in responding to phenomena, but are fraught with the interpretive problems of how to link behavioural capacities with consciousness. Instead, gathering subjective reports is seen as a more direct way of assessing the contents of consciousness. This article explores (...) three different ways of gathering subjective reports that have been discussed in recent literature on consciousness, including immediate retrospection (Schwitzgebel [2007]) and two types of introspective training (Overgaard et al. [2004]; Schwitzgebel [2008]). Although not an exhaustive survey of the range of introspective methods now used, the discussion below highlights a range of general methodological problems with introspective methods, many identified up to a century ago. It is argued that none of the methodological problems established in earlier criticisms of the use of subjective reports have been dealt with, yet are still valid criticisms. Given that this is not the first time proponents of introspective, subjective measures of conscious have failed to answer these criticisms, this raises the question of whether the goal of providing a measure of consciousness is a methodological muddle worth pursuing.

This paper argues that the many and various conceptions of consciousness propounded by cognitive scientists and philosophers can all be understood as constituted with reference to four fundamental sorts of criterion: epistemic (concerned with kinds of consciousness), semantic (dealing with orders of consciousness), physiological (reflecting states of consciousness), and pragmatic (seeking to capture types of consciousness). The resulting four-fold taxonomy, intended to be exhaustive, suggests that all of the distinct varieties of consciousness currently encountered in cognitive neuroscience, the philosophy of (...) mind, clinical psychology, and other related fields ultimately refer to a unified natural process, analysed under four general aspects. The proposed taxonomy will, it is hoped, possess sufficient clarity to serve as a sound theoretical framework for further scientific studies, and to count as a significant step in the direction of a properly formulated unified concept of consciousness.

Block’s well-known distinction between phenomenal consciousness and access consciousness has generated a large philosophical literature about putative conceptual connections between the two. The scientific literature about whether they come apart in any actual cases is rather smaller. Empirical evidence gathered to date has not settled the issue. Some put this down to a fundamental methodological obstacle to the empirical study of the relation between phenomenal consciousness and access consciousness. Block (2007) has drawn attention to the methodological puzzle and attempted to (...) answer it. While the evidence Block points to is relevant and important, this paper puts forward a more systematic framework for addressing the puzzle. To give it a label, the approach is to study phenomenal consciousness as a natural kind. The approach allows consciousness studies to move beyond the initial means of identifying instances of the kind, like verbal report, and to find its underlying nature. It is wellrecognised that facts about an underlying kind may allow identification of instances of the kind that do not match the initial means of identification (cp. non-liquid samples of water). This paper shows that the same method can be deployed to investigate phenomenal consciousness independently of access consciousness. (shrink)

The sense of agency, that is the sense that one is the agent of one’s bodily actions, is one component of our self-consciousness. Recently, Wegner and colleagues have developed a model of the causal history of this sense. Their model takes it that the sense of agency is elicited for an action when one infers that one or other of one’s mental states caused that action. In their terms, the sense of agency is elicited by the inference to apparent mental (...) state causation. Here, I argue that this model is inconsistent with data from developmental psychology that suggests children can identify the agent behind an action without being capable of understanding the relationship between their intentions and actions. Furthermore, I argue that this model is inconsistent with the preserved sense of agency in autism. In general, the problem is that there are cases where subjects can experience themselves as the agent behind their actions despite lacking the resources to make the inference to apparent mental state causation.

Commentary on the Toward a Science of Consciousness Conference, Tucson 2008.

The Cambridge Handbook of Consciousness is the first of its kind in the field, and its appearance marks a unique time in the history of intellectual inquiry on the topic. After decades during which consciousness was considered beyond the scope of legitimate scientific investigation, consciousness re-emerged as a popular focus of research towards the end of the last century, and it has remained so for nearly 20 years. There are now so many different lines of investigation on consciousness that the (...) time has come when the field may finally benefit from a book that pulls them together and, by juxtaposing them, provides a comprehensive survey of this exciting field. An authoritative desk reference , which will also be suitable as an advanced textbook. (shrink)

Though active in the arts herself, Dr. Richards (psychology, Saybrook Graduate School, San Francisco; psychiatry, Harvard Medical School; McLean Hospital, Belmont, Massachusetts) views creativity more broadly and as essential to survival. As someone who helped break new ground in the assessment of creativity in the general population, she introduces 13 chapters in which interdisciplinary thinkers probe the "originality of everyday life" in individual and societal contexts. Perspectives range from Piaget's developmental stages and the more positive aspects of television viewing to (...) chaos theory and Zen Buddhism. In integrating these views, the editor enumerates the benefits of living creatively. (shrink)

Conference Report for Toward a Science of Consciousness Tucson Conference, April 4- 8, 2006.

The Latin conscius does not translate anything like mind or consciousness. Only in the mid-nineteenth century do we find the first attempts to study consciousness as its own discipline. Wundt, James, and Freud disagreed about how to approach the science of consciousness, although agreeing that psychology was a 'science of consciousness' that takes lived biological experience as its object. The behaviorists vetoed this idea. By the 1950s, for cognitive science, mind (conscious and unconscious) was considered analogous to computer software. Recently, (...) the science of consciousness has returned as Consciousness Studies, a new interdisciplinary synthesis of neuroscience, psychology, philosophy, and cultural anthropology. But what is new in this renaissance of the science of consciousness? New first, second and third person approaches all propose to take consciousness itself as a variable. This approach is as controversial as the nineteenth-century science of consciousness--controversy perhaps inherent to any science of consciousness. (shrink)

One day someone will write a book that explains consciousness. The book will put forward a theory that closes the “explanatory gap” between conscious experience and brain activity, by showing how a brain state could in principle amount to a state of consciousness. But it will do more. It will demonstrate just why this particular brain state has to be this particular experience. As Dan Lloyd puts it in his philosophical novel, Radiant Cool: “What we need is a transparent theory. (...) One that, once you get it, you see that anything built like this will have this particular conscious experience.”1. (shrink)

The purpose of this book is to build towards an explanation of just what the matter is.

Consciousness, 'the last great mystery for science', has now become a hot topic. How can a physical brain create our experience of the world? What creates our identity? Do we really have free will?

A Review of ASSC-9 at Cal-Tech, June 24-27, 2005.

The life sciences in the 20th century were guided to a large extent by a reductionist program seeking to explain biological phenomena in terms of physics and chemistry. Two scientists who figured prominently in the establishment and dissemination of this program were Jacques Loeb in biology and Ivan P. Pavlov in psychological behaviorism. While neither succeeded in accounting for higher mental functions in physical-chemical terms, both adopted positions that reduced the problem of consciousness to the level of reflexes and associations. (...) The intellectual origins of this view and the impediment to the study of consciousness as an object of inquiry in its own right that it may have imposed on peers, students, and those who followed is explored.

The interest of this is threefold. First, patients with altered states of consciousness continue to represent a major clinical problem in terms of clinical assessment of consciousness and daily management.

There are two broad classes of empirical theories of consciousness, which I will call the biological and the functional. The biological approach is based on empirical correlations between experience and the brain. For example, there is a great deal of evidence that the neural correlate of visual experience is activity in a set of occipetotemporal pathways, with special emphasis on the infero-temporal cortex. The functionalist approach is a successor of behaviorism, the view that mentality can be seen as tendencies to (...) emit certain behavioral outputs given certain sensory inputs. The trouble with behaviorism is that it did not allow that mental states were causes and effects, but functionalists do allow this. They characterize consciousness in terms of its causal role: the causal influence on it from inputs and other mental states, and its causal efficacy with respect to other mental states and behavior. The central idea of functionalism is a proposal about the concept of consciousness, but scientific functionalists have filled the view in with empirical details—the idea is that a representation is conscious if it is broadcast in a global neuronal workspace. The functional approach says consciousness is a role, whereas the biological approach says consciousness is a realizer of that role. For example, one could take solubility to be a role—dissolving in certain circumstances—or, as with the biological view of consciousness, the physico-chemical configuration that has that role. The.

Concise and understandable, the book explains pertinent findings of modern neuroscience and describes how consciousness arises in complex brains.

In his novel Remembrance of Things Past, Marcel Proust argues that conventional descriptions of the phenomenology of consciousness are incomplete because they focus too much on the highly-salient sensory information that dominates each moment of awareness and ignore the network of associations that lies in the background. In this paper, I explicate Proust’s theory of conscious experience and show how it leads him directly to a theory of aesthetic perception. Proust’s division of awareness into two components roughly corresponds to William (...) James’ division of the stream of thought into a “nucleus” and “fringe.” Proust argues that the function of art is to evoke the underlying associative network indirectly in the mind of the observer by using carefully chosen sensory surfaces to control the stream of thought. I propose a possible neural basis for this Proustian/Jamesian phenomenology, and argue that the general principles of Proustian aesthetics can be applied to all forms of art. I conclude that a scientific theory of art should follow in a straightforward manner from a scientific theory of consciousness. (shrink)

This important new book analyses these core issues and reviews the evidence from both introspection and experiment.

In "The Quest for Consciousness," Caltech neuroscientist Christof Koch explores the biological basis of consciousness.

Many sophisticated essays and books have been written about the topic of consciousness. My own contributions date back some twenty-five years in an essay entitled 'Problems concerning the structure of consciousness' (Pribram 1976), and five years before that in delineating the difference between brain processes that are coordinate with awareness and those that are coordinate with habitual behavior (Pribram 1971a). I have been intrigued by what has been written since and take this occasion to reassess a few of the major (...) issues that have arisen. (shrink)
