In this paper we provide a philosophical analysis of the Hard Problem of consciousness and the implications of conceivability scenarios for current neuroscientific research. In particular, we focus on one of the most prominent neuroscientific theories of consciousness, integrated information theory (IIT). After a brief introduction on IIT, we present Chalmers’ original formulation and propose our own layered view of the hard problem, showing how 2 separate issues can be distinguished. More specifically, we argue that it’s possible to disentangle a (...) core problem of consciousness from a layered hard problem, the latter being essentially connected to Chalmers’ conceivability argument. We then assess the relation between the Hard Problem and IIT, showing how the theory resists conceivability scenarios, and how it is equipped to face up to the hard problem in its broadest acceptation.

By “strong representationalism” (“SR” hereafter), I mean a version of naturalistic philosophy of mind which first naturalizes intentionality by identifying it with causation to physical properties and then naturalizes phenomenology by identifying it with intentionality or making them co-supervene on each other (Montague [2010]). Most specifically, SR will be taken as the conjunction of causal-function semantics and the intentionality-phenomenology identity thesis, the latter of which entails what I call “converse intentionalism”, the principle that experiential content supervenes on phenomenology. Because of (...) this identity thesis, SR enjoys some phenomenological plausibility which is absent from traditional physicalism of mind. However, in this paper, I shall raise an integration challenge to SR by arguing that its foundational principles do not integrate easily. I will also explore some strategies open to SR for addressing my challenge, and argue that by invoking those strategies, SR either loses its phenomenological plausibility or undermines causal-function semantics. I conclude that if my argument is correct, it provides us reason to search for new principles to replace SR’s foundations. (shrink)

Preston & de Waal are understandably cautious in applying their model to autism. They emphasise multiple cognitive impairments in autism, including prefrontal-executive, cerebellar-attention, and amygdala-emotion recognition deficits. Further empirical examination of imitation ability in autism may reveal deficits in the neural and cognitive basis of perception-action mapping that have a specific relation to the empathic deficit.

ABSTRACT Lewtas [2017] recently articulated an argument claiming that emergent conscious causal powers are impossible. In developing his argument, Lewtas makes several assumptions about emergence, phenomenal consciousness, categorical properties, and causation. We argue that there are plausible alternatives to these assumptions. Thus, the proponent of emergent conscious causal powers can escape Lewtas’s challenge.

This paper proposes a way to understand transformative choices, choices that change ‘who you are.’ First, it distinguishes two broad models of transformative choice: 1) ‘event-based’ transformative choices in which some event—perhaps an experience—downstream from a choice transforms you, and 2) ‘choice-based’ transformative choices in which the choice itself—and not something downstream from the choice—transforms you. Transformative choices are of interest primarily because they purport to pose a challenge to standard approaches to rational choice. An examination of the event-based transformative (...) choices of L. A. Paul and Edna Ullman-Margalit, however, suggests that event-based transformative choices don’t raise any difficulties for standard approaches to rational choice. An account of choice-based transformative choices—and what it is to be transformed—is then proposed. Transformative choices so understood not only capture paradigmatic cases of transformative choice but also point the way to a different way of thinking about rational choice and agency. (shrink)

In Section 5 of his interesting article, Goldman suggests that the consideration of imaginary cases can be valuable in the analysis of our psychological concepts. In particular, he argues that we can imagine a system that is isomorphic to us under any functional description, but which lacks qualitative mental states, such as pains and color sensations. Whether or not such a being is empirically possible, it certainly seems to be logically possible, or conceptually coherent. Goldman argues from this possibility to (...) the conclusion that our concepts of qualitative mental states cannot be analyzed entirely in functional terms. (shrink)

This paper suggests that reference to phenomenal qualities is best understood as involving iconicity, that is, a passage from sign-vehicle to object that exploits a similarity between the two. This contrasts with a version of the ‘phenomenal concept strategy’ that takes indexicality to be central. However, since it is doubtful that phenomenal qualities are capable of causally interacting with anything, indexical reference seems inappropriate. While a theorist like David Papineau is independently coming to something akin to iconicity, I think some (...) of the awkwardness that plagues his account would be remedied by transitioning to a more inclusive philosophy of signs.

Information processing in neural systems can be described and analysed at multiple spatiotemporal scales. Generally, information at lower levels is more fine-grained but can be coarse-grained at higher levels. However, only information processed at specific scales of coarse-graining appears to be available for conscious awareness. We do not have direct experience of information available at the scale of individual neurons, which is noisy and highly stochastic. Neither do we have experience of more macro-scale interactions, such as interpersonal communications. Neurophysiological evidence (...) suggests that conscious experiences co-vary with information encoded in coarse-grained neural states such as the firing pattern of a population of neurons. In this article, we introduce a new informational theory of consciousness: Information Closure Theory of Consciousness (ICT). We hypothesise that conscious processes are processes which form non-trivial informational closure (NTIC) with respect to the environment at certain coarse-grained scales. This hypothesis implies that conscious experience is confined due to informational closure from conscious processing to other coarse-grained scales. ICT proposes new quantitative definitions of both conscious content and conscious level. With the parsimonious definitions and a hypothesise, ICT provides explanations and predictions of various phenomena associated with consciousness. The implications of ICT naturally reconcile issues in many existing theories of consciousness and provides explanations for many of our intuitions about consciousness. Most importantly, ICT demonstrates that information can be the common language between consciousness and physical reality. (shrink)

Shaun Gallagher has actively looked into the possibility that psychopathologies involving “thought insertion” might supply a counterexample to the Cartesian principle according to which one can always recognize one’s own thoughts as one’s own. Animated by a general distrust of a priori demonstrations, Gallagher is convinced that pitting clinical cases against philosophical arguments is a worthwhile endeavor. There is no doubt that, if true, a falsification of the immunity to error through misidentification would entail drastic revisions in how we conceive (...) the boundary between self and other. However, I argue that (1) the idea of unearthing an exception to the Cartesian thesis is, on further reflection, not a realistic prospect and that (2) this casts doubt on the attempt to conjoin first-person phenomenology and third-person cognitive science in the service of philosophical debates.

Is conceptual analysis required for reductive explanation? If there is no a priori entailment from microphysical truths to phenomenal truths, does reductive explanation of the phenomenal fail? We say yes . Ned Block and Robert Stalnaker say no.

Prompted by the thesis that an organism’s umwelt possesses not just a descriptive dimension, but a normative one as well, some have sought to annex semiotics with ethics. Yet the pronouncements made in this vein have consisted mainly in rehearsing accepted moral intuitions, and have failed to concretely further our knowledge of why or how a creature comes to order objects in its environment in accordance with axiological charges of value or disvalue. For want of a more explicit account, theorists (...) writing on the topic have relied almost exclusively on semiotic insights about perception originally designed as part of a sophisticated refutation of idealism. The end result, which has been a form of direct givenness, has thus been far from convincing. In an effort to bring substance to the right-headed suggestion that values are rooted in the biological and conform to species-specific requirements, we present a novel conception that strives to make explicit the elemental structure underlying umwelt normativity. Building and expanding on the seminal work of Ayn Rand in metaethics, we describe values as an intertwined lattice which takes a creature’s own embodied life as its ultimate standard; and endeavour to show how, from this, all subsequent valuations can in principle be determined.

Several language experiments have been carried out on apes and other animals aiming to narrow down the presumed qualitative gap that separates humans from other animals. These experiments, however, have been driven by the understanding of language as a purely symbolic sign system, often connected to a profound disinterest for language use in real situations and a propensity to perceive grammatical and syntactic information as the only fundamental aspects of human language. For these reasons, the language taught to apes tends (...) to discard iconic and indexical elements in favour of symbolic signs. This paper sheds light on the iconic components of human language, with close attention to the iconic properties of language as present in the ape language experiments. We emphasise the role of the body in the interpretation and production of iconic signs, while demonstrating the need to take into account the Umwelt theory in the research paradigm of the experiments. Uexküll’s Umwelt theory is used to exemplify the methodological problems connected to the teaching of human language to other animal species; furthermore, we discuss how the modelling capacities of language affect the biological layer that constitutes the animal Umwelt. Language is analysed as a particular case of Umwelt transition, and as such its implications are further discussed in the article. With this paper, we enrich the discussion surrounding the human-ape pidgin language by advocating for the need to include iconic components as vital parts of this research area. With this inclusion, we uncover the inter-dependency of iconic, indexical and symbolic signs in human language, aiming to further develop the research paradigm of the ape language experiments.

The relationship between consciousness and brain, subject and body, appears today far away from being elucidated. All attempts to reduce consciousness and subject to the brain end up abolishing the subject, i.e., what is evidently most relevant for each one of us. Luigi Giussani proposes a method to investigate human consciousness based on the analysis of oneself personal experience, verifiable by every human being. He is very attentive to avoiding during the experiential analysis interference of prejudices, ideological conceptions, and conjectures. (...) His method remains perfectly coherent and open to all contributions from neuroscience and scientific discoveries. He leaves completely open the major question about the relationship between brain physical-chemical functioning and subjective experience, individual consciousness. A comparison between Giussani’s method and the starting point and the fundamental assumption that lays the basis of various modern neuroscientific conceptions of consciousness is conducted. A discussion about the assumption that stays at the basis of the various neuroscientific currents appears necessary and the method proposed by Giussani may constitute a common and acceptable by everyone background for future development and advances in studying the greatest problem of our culture, the relation between brain and human consciousness.

In this paper I argue that the Integrated Information Theory of Consciousness has an underlying emergentist metaphysics, specifically of a kind that has received minimal attention and we may call functionalist emergentism. I will try to show that in this scientific theory conscious experience is a functional-role property possessed by the whole system, not by their parts, which is dependent on, but also (purportedly) causally powerful over and above, the properties of the parts. However, I will argue that depicting conscious (...) experience as a functional-role emergent property threatens the whole coherence of the theory because, by definition, functional-realizers do all the causal work associated with the instantiation of any functional-role property on any occasion. Hence, to preserve the causal power of consciousness, which, as we will see, is one of the fundamental building blocks of the theory, linked to the assertion of the very existence of consciousness, phenomenal properties should be re-thought as realizers of the relevant informationally integrated causal-roles.

It is often said that ‘what it is like’-knowledge cannot be acquired by consulting testimony or reading books [Lewis 1998; Paul 2014; 2015a]. However, people also routinely consult books like What It Is Like to Go to War [Marlantes 2014], and countless ‘what it is like’ articles and youtube videos, in the apparent hope of gaining knowledge about what it is like to have experiences they have not had themselves. This article examines this puzzle and tries to solve it by (...) appealing to recent work on knowing-wh ascriptions. In closing I indicate the wider significance of these ideas by showing how they can help us to evaluate prominent arguments by Paul [2014; 2015a] concerning transformative experiences. (shrink)

The emergence of electronic computers in the last thirty years has given rise to many interesting questions. Many of these questions are technical, relating to a machine’s ability to perform complex operations in a variety of circumstances. While some of these questions are not without philosophical interest, the one question which above all others has stimulated philosophical interest is explicitly non-technical and it can be expressed crudely as follows: Can a machine be said to think and, if so, in what (...) sense? The issue has received much attention in the scholarly journals with articles and arguments appearing in great profusion, some resolutely answering this question in the affirmative, some, equally resolutely, answering this question in the negative, and others manifesting modified rapture. While the ramifications of the question are enormous I believe that the issue at the heart of the matter has gradually emerged from the forest of complications. (shrink)

This essay reviews Theatre, Communication, Critical Realism (2010) by Tobin Nellhaus. It begins by outlining the objective of the book and proceeds to evaluate its central argument. The objective is to develop a theory of theatre founded on the premises of critical realism and thereby theoretically situate theatrical performance in its socio-cultural matrix. The argument is that critical realism is effective for developing a comprehensive account of theatrical performance because it has the capacity to reveal truths about the structure of (...) social reality (that correspond to those articulated by critical realism). In the second part of the review, employing the methods of conceptual analysis, I propose that Nellhaus’s thesis of ‘ontological doubling’ (which claims that performance doubles human agency) is undermined by certain epistemological presuppositions regarding the ontology of fictional characters.

If the octopus were conscious, what would its consciousness be like? This paper investigates the structure octopus consciousness, if existent, is likely to exhibit. Presupposing that the configuration of an organism’s consciousness is correlated with that of its nervous system, it is unlikely that the structure of the sort of conscious experience that would arise from the highly decentralized octopus nervous system would bear much resemblance to those of vertebrates. In particular, octopus consciousness may not exhibit unity, which has long (...) been assumed to be the normal or default structure of consciousness. The octopus nervous system is characterized by the following features: its three anatomically distinct components have extensive functional autonomy and little intercommunication; much of the sensory processing and motor control routines—that in vertebrates are localized in the brain—take place within the peripheral arm nervous system; and proprioception and somatotopic representation are significantly downplayed. In this paper, I present the octopus as a highly successful biological organism in which it is plausible that the unified model of consciousness does not hold. (shrink)

Can phenomenal consciousness be given a reductive natural explanation? Exponents of an ‘explanatory gap’ between physical, functional and intentional facts, on the one hand, and the facts of phenomenal consciousness, on the other, argue that there are reasons of principle why phenomenal consciousness cannot be reductively explained: Jackson, ; Levine,, ; McGinn ; Sturgeon, ; Chalmers,. Some of these writers claim that the existence of such a gap would warrant a belief in some form of ontological dualism, whereas others argue (...) that no such entailment holds. In the other main camp, there are people who argue that a reductive explanation of phenomenal consciousness is possible in principle, and yet others who claim, moreover, to have provided such an explanation in practice.

This is the editors' introduction to an edited volume devoted to the relation between phenomenology and naturalism across several philosophical domains, including: epistemology, metaphysics, history of philosophy, and philosophy of science and ethics.

In Consciousness Explained and other works, Daniel Dennett uses the concept of phenomenology (along with his variant, called heterophenomenology) in almost complete disregard of the work of Husserl and his successors in German and French philosophy. Yet it can be argued that many of the most important ideas of Husserl, Merleau-Ponty and others (and not just the idea of intentionality) reappear in Dennett's work in only slightly altered form. In this article I try to show this in two ways, first (...) by talking in a general way about Dennett's phenomenology, and second by examining his treatment of the concept of the self. In both cases I argue that Dennett should have read his Husserl and Merleau-Ponty more carefully, since in the end his (hetero-) phenomenology is methodologically incoherent and suffers from something like a weakness of will. This emerges especially in his use of the notion of fiction. (shrink)

In this paper we try to diagnose one reason why the debate regarding the Hard Problem of consciousness inevitably leads to a stalemate: namely that the characterisation of consciousness assumed by the Hard Problem is unjustified and probably unjustifiable. Following Dennett : 4–6, 1996, Cognition 79:221–237, 2001, J Conscious Stud 19:86, 2012) and Churchland :402–408, 1996, Brainwise: studies in neurophilosophy. MIT Press, Cambridge, MA, 2002), we argue that there is in fact no non-question begging argument for the claim that consciousness (...) is a uniquely Hard Phenomenon. That is; there is no non-question begging argument for the claim that consciousness is necessarily in explicable in terms of the structure and function of mental states. Unfortunately the debate has not moved on because the majority of materialists feel the pull of the at least one of, what we call, the ‘key’ intuitions that supposedly support dualism and the existence of a Hard Phenomenon and so try to accommodate them rather than denying them. Although this a possible response to the intuitions it tends to mask the fact that there is in fact no argument for the existence of a Hard Phenomenon. So we end up participating in our own hornswoggling :402–408, 1996) and chasing our tails trying to answer a question we should in fact ignore. We have no reason to think there is a Hard Problem of consciousness because we have no reason to think the Hard Phenomenon exists. (shrink)

Non-human animal chimeras, containing human neurological cells, have been created in the laboratory. Despite a great deal of debate, the status of such beings has not been resolved. Under normal definitions, such a being could either be unconventionally human or abnormally animal. Practical investigations in animal sentience, artificial intelligence, and now chimera research, suggest that such beings may be assumed to have no legal rights, so philosophy could provide a different answer. In this vein, therefore, we can ask: What would (...) a chimera, if it could think, think about? Thinking is used to capture the phenomena of a novel, chimeric being perceiving its terrible predicament as no more than a laboratory experiment. The creation of a thinking chimera therefore forces us to reconsider our assumptions about what makes human beings (potentially) unique (and other sentient animals different), because, as such, a chimera’s existence bridges our social and legal expectations about definitions of human and animal. Society has often evolved new social norms based on different kinds of (ir)rational contrivances; the imperative of non-contradiction, which is defended here, therefore requires a specific philosophical response to the rights of a thinking chimeric being.

In her very interesting ‘First-personal modes of presentation and the problem of empathy’, L. A. Paul argues that the phenomenon of empathy gives us reason to care about the first person point of view: that as theorists we can only understand, and as humans only evince, empathy by appealing to that point of view. We are skeptics about the importance of the first person point of view, although not about empathy. The goal of this paper is to see if we (...) can account for empathy without the ideology of the first person. We conclude that we can. (shrink)

The “happy fish” passage concluding the “Autumn Floods” chapter of the Classical Chinese text known as the Zhuangzi has traditionally been seen to advance a form of relativism which precludes objectivity. My aim in this paper is to question this view with close reference to the passage itself. I further argue that the central concern of the two philosophical personae in the passage – Zhuangzi and Huizi – is not with the epistemic standards of human judgements (the established view since (...) Hansen, “The Relatively Happy Fish”), but with the more basic problem of species-specific perspectives. On my reading, Zhuangzi’s emphatic positionality in the passage – on the dam, accompanied by his friend Huizi – plausibly suggests a circumspect reflection on the limitedness of human knowledge. It is significant that Zhuangzi’s knowledge of fish happiness is avowedly from a certain place, and not absolute. But there is still a sense in which this view is objective: namely, insofar as it adequately accounts for an inherently human perspective on the world. I call this modest form of relativism ‘Species Relativism’, which, crucially, leaves room for objectivity, even though a fully objective (i.e. absolute) view of the world is not accessible to humans.

I argue that the explanatory gap is generated by factors consistent with the view that qualia are physical properties. I begin by considering the most plausible current approach to this issue based on recent work by Valerie Hardcastle and Clyde Hardin. Although their account of the source of the explanatory gap and our potential to close it is attractive, I argue that it is too speculative and philosophically problematic. I then argue that the explanatory gap should not concern physicalists because (...) it makes excessive demands on physical theory. (shrink)

The fact that we can engage in first-person discourse about our own mental states seems, intuitively, to be bound up with consciousness. David Rosenthal draws upon this intuition in arguing for his higher-order thought theory of consciousness. Rosenthal's argument relies upon the assumption that the truth-conditions for "p" and "I think that p" differ. It is argued here that the truth-conditional schema debars "I think" from playing one of its roles and thus is not a good test for what is (...) asserted when "I think" is employed in making an assertoric utterance. The critique of Rosenthal's argument allows us to make explicit the intuitions which shape higher-order representation theories of consciousness in general. Consciousness and first-person mental discourse seem to be connected primarily because consciousness is an epistemic term, used to denote first-person knowledge of minds. Higher-order thought theories of consciousness draw upon this epistemic notion of consciousness, and because self-knowledge seems to involve higher-order representation, the higher-order theorist can deploy what is in effect an "error theory" about conscious experience disguised as a kind of conceptual analysis of our ordinary concept of a conscious mental state. The conclusion reached is that there is unlikely to be a simple or direct path from considerations about mental discourse to conclusions about the nature of consciousness. (shrink)
