Opinion - Paper under review Deep Learning and the Global Workspace Theory Rufin VanRullen1, 2 and Ryota Kanai3 1CerCo, CNRS UMR5549, Toulouse, France 2ANITI, Universit´ede Toulouse, France 3Araya Inc, Tokyo. Japan Abstract Recent advances in deep learning have allowed Artificial Intelligence (AI) to reach near human-level performance in many sensory, perceptual, linguistic or cognitive tasks. There is a growing need, however, for novel, brain-inspired cognitive architectures. The Global Workspace theory refers to a large-scale system integrating and distributing infor- mation among networks of specialized modules to create higher-level forms of cognition and awareness. We argue that the time is ripe to consider explicit implementations of this theory using deep learning techniques. We propose a roadmap based on unsu- pervised neural translation between multiple latent spaces (neural networks trained for distinct tasks, on distinct sensory inputs and/or modalities) to create a unique, amodal global latent workspace (GLW). Potential functional advantages of GLW are reviewed, along with neuroscientific implications. 1 Cognitive neural architectures in brains and ma- chines Deep learning denotes a machine learning system using artificial neural networks with multiple \hidden" layers between the input and output layers. Although the underlying theory is more than 3 decades old [1, 2], it is only in the last decade that these systems have started to fully reveal their potential [3]. Many of the recent breakthroughs in AI (Artificial Intelligence) have been fueled by deep learning. Neuroscientists have been quick to point out the similarities (and differences) between the brain and these deep artificial neural networks [4{9]. The advent of deep learning has allowed the efficient computer implementation of perceptual and cognitive functions that had been so far arXiv:2012.10390v2 [cs.AI] 20 Feb 2021 inaccessible. -

On the one hand, the belief that nonhuman animals suffer and feel pain is what draws many people to want to study animal welfare in the first place. Animal welfare is seen as fundamentally different from plant “welfare” or the welfare of works of art precisely because of the widely held belief that animals have feelings and experience emotions in ways that plants or inanimate objectsdhowever valuableddo not (Midgley, 1983; Regan, 1984; Rollin, 1989; Singer, 1975). On the other hand, consciousness is also the most elusive and difficult to study of any biological phenomenon (Blackmore, 2012; Koch, 2004). Even with our own human consciousness, we are still baffled as to how Advances in the Study of Behavior, Volume 47 ISSN 0065-3454 © 2014 Elsevier Inc. -

Indeed, there are many definitions of consciousness and multiple approaches to study the neural correlates of consciousness (NCC). Therefore, the main aim of this article is to collect data on the various theories of consciousness published between 2007–2017 and to synthesize them to provide a general overview of this topic. To describe each theory, we developed a thematic grid called the dimensional model, which qualitatively and quantitatively analyzes how each article, related to one specific theory, debates/analyzes a specific issue. -
Iv. Causal Interactions of Consciousness, Unconscious Mind and Brain1
IV. CAUSAL INTERACTIONS OF CONSCIOUSNESS, UNCONSCIOUS MIND AND BRAIN1 MAX VELMANS 1. WHAT NEEDS TO BE EXPLAINED The potential effect of the mind on the body is also taken for granted in psychosomatic medicine. But how the conscious mind exercises its influ- ence is not easy to understand. In principle, there are four distinct ways in which body/brain and mind/consciousness might enter into causal relation- ships. There might be physical causes of physical states, physical causes of mental states, mental causes of mental states, and mental causes of physical states. Establishing which forms of causation are effective in practice is important, not just for a deeper understanding of mind/body interactions, but also for the proper treatment of some forms of illness and disease. Within conventional medicine, physicalÆphysical causation is taken for granted. Consequently, the proper treatment for physical disorders is assumed to be some form of physical intervention. Psychiatry takes the efficacy of physicalÆmental causation for granted, along with the assump- tion that the proper treatment for psychological disorders may involve psychoactive drugs, neurosurgery and so on. Many forms of psychotherapy take mentalÆmental causation for granted, and assume that psychological disorders can be alleviated by means of “talking cures”, guided imagery, hypnosis and other forms of mental intervention. Psychosomatic medicine assumes that mentalÆphysical causation can be effective. Consequently, under some circumstances, a physical disorder (for example, hysterical paralysis) may require a mental (psychotherapeutic) intervention. Given the extensive evidence for all these causal interactions (cf. readings in Velmans 1996a), how are we to make sense of them? 2. -

Global Workspace Theory and Animal Consciousness
19 August 2020 Global Workspace Theory and Animal Consciousness Jonathan Birch Centre for Philosophy of Natural and Social Science, London School of Economics and Political Science, Houghton Street, London, WC2A 2AE, UK. Email: [email protected] Webpage: http://personal.lse.ac.uk/birchj1 This is a preprint of an article that will appear in Philosophical Topics. 7082 words 1 Abstract: 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 non-human 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 (determinately) 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. Key words: animal consciousness, phenomenal consciousness, consciousness science, global workspace theory, phenomenal concepts 2 1. Carruthers’ surprising conditional For more than thirty years, scepticism about attributions of phenomenal consciousness1 to (states of) non-human animals has been a major theme in Peter Carruthers’ work (Carruthers 1989, 1992, 1999, 2000, 2004, 2005, 2018a,b, 2019, 2020). -
Searle's Critique of the Multiple Drafts Model of Consciousness 1
FACTA UNIVERSITATIS Series: Linguistics and Literature Vol. 7, No 2, 2009, pp. 173 - 182 SEARLE'S CRITIQUE OF THE MULTIPLE DRAFTS MODEL OF CONSCIOUSNESS 1 UDC 81'23(049.32) Đorđe Vidanović Faculty of Philosophy, University of Niš, Serbia E-mail: [email protected] Abstract. In this paper I try to show the limitations of John Searle's critique of Daniel Dennett's conception of consciousness based on the idea that the computational architecture of consciousness is patterned on the simple replicating units of information called memes. Searle claims that memes cannot substitute virtual genes as expounded by Dennett, saying that the spread of ideas and information is not driven by "blind forces" but has to be intentional. In this paper I try to refute his argumentation by a detailed account that tries to prove that intentionality need not be invoked in accounts of memes (and consciousness). Key words: Searle, Dennett, Multiple Drafts Model, consciousness,memes, genes, intentionality "No activity of mind is ever conscious" 2 (Karl Lashley, 1956) 1. INTRODUCTION In his collection of the New York Times book reviews, The Mystery of Conscious- ness (1997), John Searle criticizes Daniel Dennett's explanation of consciousness, stating that Dennett actually renounces it and proposes a version of strong AI instead, without ever accounting for it.

The Phenomenology of the Self-Conscious Mind
The Phenomenology of the Self-Conscious Mind Robert G. Mays, B.Sc. Suzanne B. Mays Chapel Hill, NC ABSTRACT: The phenomenon of a near-death experiencer's veridical perceptions during the out-of-body experience (OBE) strongly suggests the existence of a self-conscious mind as a "field of consciousness," a region of space where a person's consciousness exists. In the out-of-body state, the mind appears to be nonmaterial and completely independent of the physical body. Ordinarily, though, the self-conscious mind appears as an autonomous entity united with the brain and body. In this united state, the self-conscious mind operates through the mediation of the brain. This view is supported by evidence from neurological phenomena such as subjective antedating of sensory experiences and mental force. This evidence suggests that a nonneural agency induces conscious experience and self-conscious awareness. Phenomena from OBEs, including apparent subtle interactions with physical processes such as light, sound, and physical objects, as well as reported interactions with "in-body" persons, support the view that the self-conscious mind is able to interact in some physical way with the brain. Neurological phenomena such as Benjamin Libet's (1985) delayed awareness of willed action can be reconsidered successfully in light of this view. Such efforts might also prove useful, for example, in explaining phantom limb phenomena. KEY WORDS: near-death experience; out-of-body experience; mind-body problem; self-conscious mind; veridical perception. Robert G. Mays, B.Sc., is a retired senior software engineer and Suzanne B.

The First Step in the Case for Great Ape Equality: The Argument for Other Minds Kristin Andrews A defense of equality for great apes must begin with an understanding of the opposition and an acknowledgement of the most basic point of disagreement. For great apes to gain status as persons in our community, we must begin by determining what the multitude of different definitions of "person" have in common. Finding that great apes fulfill the requirements of any one specific theory of personhood is insufficient, for these theories are highly controversial, and a critique of the theory will undermine the status of great apes as persons. Instead, the first step in the argument for ape equality must be a defense of their self-consciousness. This notion is one thing all plausible theories of personhood have in common. Contrary to most people's common conceptions, many philosophers have argued that great apes, as well as all nonhuman animals, lack consciousness.1 This notion must be demolished before any argument for the equality of great apes can be fully defended. -

A HEURISTIC FOR ENVIRONMENTAL VALUES AND ETHICS, AND A PSYCHOMETRIC INSTRUMENT TO MEASURE ADULT ENVIRONMENTAL ETHICS AND WILLINGNESS TO PROTECT THE ENVIRONMENT DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Ronald B. Meyers, M.A. * * * * * The Ohio State University 2002 Dissertation Committee: Joe E. Heimlich, Adviser Approved by Herbert Asher Donald C. Hubin __________________________ Tomas Koontz Adviser Graduate Program in Natural Resource Copyright by Ronald Bennett Meyers 2002 ABSTRACT The need for instruments to objectively and deeply measure public beliefs concerning environmental values and ethics, and relationship to environmental protection led to a project to integrate analytical techniques from ethics and educational psychology to identify beliefs in theories of value and obligation (direct and indirect), develop a 12- category system of environmental ethics, and a psychometric instrument with 5 scales and 7 subscales, including a self-assessment instrument for environmental ethics. The ethics were tested for ability to distinguish between beliefs in need to protect environment for human interests versus the interests or rights of animals and the environment. A heuristic for educators was developed for considering 9 dimensions of environmental and the ethics, and tested favorably. An exploratory survey (N = 74, 2001) of adult moral beliefs used 16 open-ended questions for moral considerability of, rights, treatment, and direct and indirect moral obligations to the environment. A 465 - item question bank was developed and administered (N = 191, 2002) to Ohio adults, and reduced to 73 items in 12 Likert-type scales (1-7, 1 strongly disagree) by analyzing internal consistency, response variability, interscale correlations, factorial, and ANOVA. -
COMPETING MODELS of CONSCIOUSNESS David Rosenthal Philosophy and Cognitive Science Graduate Center, City University of New York
COMPETING MODELS OF CONSCIOUSNESS David Rosenthal Philosophy and Cognitive Science Graduate Center, City University of New York REVISED PENULTIMATE VERSION Word count: 2,248 Graziano and colleagues (forthcoming) sketch some suggestive ways in which Graziano’s attention-schema theory (AST) of consciousness (Graziano 2013, 2019; Webb and Graziano 2015) connects with three other theories: the global-workspace theory (GWT) of Baars (1997) and Dehaene and Naccache (2001), higher-order-thought (HOT) theory (Rosenthal 2005), and illusionism (Frankish 2016). According to Graziano and colleagues, these “theories should not be viewed as rivals, but as partial perspectives on a deeper mechanism” (1). The deeper mechanism they have in mind is that of AST, which they urge constitutes “a kind of standard model that covers the basics if not the details” of consciousness (1). I’ll raise difficulties for this irenic construal of these four theories, and argue that they are in important ways theoretical competitors. Graziano and colleagues see the term ‘consciousness’ as applying to two distinct phenomena. One is “how select information reaches a state in which it is bundled centrally and can impact output systems.” They call this i-consciousness, in contrast with what they call m-consciousness, “a more mysterious, extra, experiential essence that people claim accompanies the informational content” that occurs in i-consciousness (2). The ‘m’ of ‘m- consciousness’ reflects their view that this notion is inherently mysterious. With that distinction in place, Graziano and colleagues urge that the central issue for a theoretical treatment of consciousness is “whether m-consciousness, the more ethereal notion of consciousness that people intuitively believe they have, is accurate or instead is an imperfect model of i-consciousness” (2).
