Quite a few recent models are rapidly introducing new concepts describing different levels of consciousness. This situ- ation is getting confusing because some theorists formulate their models without making reference to existing views, redun- dantly adding complexity to an already difficult problem. In this paper, I present and compare nine neurocognitive models to highlight points of convergence and divergence. Two aspects of consciousness seem especially important: perception of self in time and complexity of self-representations. To this I add frequency of (...) self-focus, amount of self-related informa- tion, and accuracy of self-knowledge. Overall, I conclude that many novel concepts (e.g., reflective, primary, core, extend- ed, recursive, and minimal consciousness) are useful in helping us distinguish between delicate variations in consciousness and in clarifying theoretical issues that have been intensely debated in the scientific literature—e.g., consciousness in rela- tion to mirror self-recognition and language.

_ Source: _Volume 94, Issue 3, pp 359 - 380 In this paper the author discusses and defends a theory of consciousness inspired by Franz Brentano, according to which every conscious experience involves a certain kind of immediate awareness of itself. All conscious experience is in a certain fundamental sense ‘self-intimating’—it constitutively involves awareness of that very awareness. The author calls this ‘the awareness of awareness thesis’, and she calls the phenomenon that it concerns ‘awareness of awareness’. The author attempts (...) to give a substantive description of what AOA consists in in two ways, first, by listing some of its positive features, and second, by comparing it and contrasting it with introspection. The idea is that there are many different ways we can be aware of our experiences, introspection being one way, AOA being another, distinct way. By clarifying the distinction between AOA and introspection, we can get a better grasp of both phenomena. (shrink)

Opponents to consciousness in fish argue that fish do not feel pain because they do not have a neocortex, which is a necessary condition for feeling pain. A common counter-argument appeals to the multiple realizability of pain: while a neocortex might be necessary for feeling pain in humans, pain might be realized differently in fish. This paper argues, first, that it is impossible to find a criterion allowing us to demarcate between plausible and implausible cases of multiple realization of pain (...) without running into a circular argument. Second, opponents to consciousness in fish cannot be provided with reasons to believe in the multiple realizability of pain. I conclude that the debate on the existence of pain in fish is impossible to settle by relying on the multiple realization argument. (shrink)

It is a widely held view that persons have privileged knowledge about their own minds, although numerous different views on what this privilege exactly consists of exist. One possible way of interpreting it is to claim that persons can refer to their own mental states in a privileged way. I will argue that this view has to be extended. Our common-sense view about reference to mental states implies that besides privileges of first-person reference to one's own mental states, there also (...) exist privileges of third-person reference to the mental states of others: Other persons can refer to all of the mental states of a person in a way that the person cannot. In a next step, I will explain that persons can take two perspectives towards their own mental states: a first-person perspective and a third-person perspective. I will conclude that the possibilities of first-person reference from a third-person perspective are limited. (shrink)

In this article, I argue that an epistemic question about knowledge of our own phenomenal states encourages a certain metaphysical picture of consciousness according to which phenomenal states are reflexive mental representations. Section 1 describes and motivates the thesis that phenomenal self-knowledge is ‘receptive’: that is, the view that a subject has knowledge of their phenomenal states only insofar as they are inwardly affected by those states. In Sections 2 and 3, I argue that this model of phenomenal self-knowledge is (...) unable to accommodate knowledge of our own phenomenology or knowledge of our own awareness. In Section 4, I seek a non-receptive model of phenomenal self-knowledge. I argue that Kriegel’s Self-Representationalist theory of consciousness is uniquely equipped to show how phenomenal self-knowledge is possible. (shrink)

Kriegel’s self-representationalist theory of phenomenal consciousness pursues two projects. The first is to offer a positive account of how conscious experience arises from physical brain processes. The second is to explain why consciousness misleadingly appears to be irreducible to the physical i.e. to ‘demystify’ consciousness. This paper seeks to determine whether SR succeeds on the second project. Kriegel trades on a distinction between the subjective character and qualitative character of conscious states. Subjective character is the property of being a conscious (...) state at all, while qualitative character determines what it is like to be in that state. Kriegel claims that SR explains why subjective character misleadingly appears irreducible, thereby neutralising the apparent irreducibility of consciousness. I argue that although SR credibly demystifies subjective character, it cannot explain why qualitative character also appears irreducible. I conclude that we should pursue the possibility of a hybrid position that combines SR with an account that does explain the apparent irreducibility of qualitative character. (shrink)

The ubiquity of inner awareness thesis states that all conscious states of normal adult humans are characterised by an inner awareness of that very state. UIA-Backers support this thesis while UIA-Skeptics reject it. At the heart of their dispute is a recalcitrant phenomenological disagreement. UIA-Backers claim that phenomenological investigation reveals ‘peripheral inner awareness’ to be a constant presence in their non-introspective experiences. UIA-Skeptics deny that their non-introspective experiences are characterised by inner awareness, and maintain that inner awareness is only gained (...) when they explicitly introspect. Each camp has put forward a range of arguments designed to resolve this dispute, but I argue that none of these arguments has genuine dialectical purchase. This leads me to develop a compromise position that trades on the contribution that affordances can make to our phenomenology. According to the Affordance Model of inner awareness, all conscious states of normal adult humans are characterised by an affordance of introspectability. In line with the UIA-Skeptic, non-introspective experiences are not characterised by inner awareness. But against the traditional UIASkeptic, non-introspective experiences are characterised by an awareness of the opportunity for introspection. On this view, our capacity to gain inner awareness of our current experience is a ubiquitous feature of our phenomenology. I show how the Affordance Model respects the driving phenomenological intuitions of both the UIA-Backers and the traditional UIA-Skeptics, and suggest that it is able to explain why neither camp achieves an accurate description of how inner awareness figures in their phenomenology.

This essay examines the grammatical structure underlying the use of the word "conscious". Despite the existence of this grammatical structure, I reject the assumption that actual consciousness has a similar structure. Specifically, I reject the claim that consciousness consists of three subtypes: state consciousness, transitive consciousness, and creature consciousness. I offer an inductive argument and a deductive argument that no such psychological entities exist. The inductive argument: given the lack of evidence or arguments for the entities and given that a (...) tripartite consciousness structure evolved from a tripartite grammatical habit, it would be far too coincidental if the grammatical distinction mirrored a psychological distinction. The deductive argument shows that absurd conclusions follow from assuming the existence of three distinct psychological entities. Furthermore, the verbal habits that motivate the distinction are rendered more intelligible under a "Unitary Thesis", the idea that verbal distinctions involving use of the word "conscious" are unified in their reliance on a single ontological unit, that of conscious experience.

In the philosophical literature on consciousness and the mind-body problem, the conceivability argument against physicalism is usually taken to support a form of dualism between physicality and phenomenality. Usually, the discussion focuses on the qualitative character of experience, which is what the phenomenal feel of a given experience is like. By contrast, the subjective character of experience, or its individuation to a given first-person subject, tends to be set aside. The aim of this paper is to present a new and (...) more robust version of the conceivability argument for dualism that appeals to the subjective character of experience. Drawing on insights by philosophers in the phenomenological tradition, I conceptualise the first-person subjective character of experience as a transcendental condition of possibility for phenomenality that cannot be reduced to third-person facts about the physical world. Given this, the mind-body problem as it pertains to consciousness does not merely concern the inability of the set of physical facts about a brain state to capture the qualitative character of experience, but concerns the existential issue of why this brain state is accompanied by first-person subjectivity at all. This allows us to reconceive the conceivability argument in a way that presents a stronger case for dualism than the traditional version of the argument. (shrink)

David Rosenthal's higher-order thought theory is one of the most widely argued for of the higher-order accounts of consciousness. I argue that Rosenthal vacillates between two models of the HOT theory. First, I argue that these models employ different concepts of 'state consciousness'; the two concepts each refer to mental state tokens, but in virtue of different properties. In one model, the concept of 'state consciousness' is more consistent with how the term is typically used, both by philosophers and scientists, (...) and in commonsense usage. This model, however, also has its problems. In the second part of the paper, I develop a modified version of Rosenthal's transitivity principle, thereby avoiding some complications that stem from the original transitivity principle. I suggest that Rosenthal occasionally employs this modified model himself, and that the inconsistency identified in the first section of this paper might really reflect Rosenthal's vacillation between these two versions of the transitivity principle. I offer one explanation for how this equivocation may have occurred. These two versions would result if articulations of the transitivity principle employed the term 'mental state' inconsistently, to refer on some occasions merely to mental state types, and on others, to tokened mental states. I conclude by arguing, contrary to Rosenthal and others, that the theory is not incompatible with view that conscious states are uniquely casual efficacious. (shrink)

How can we investigate the foundations of consciousness? In addressing this question, we will focus on the two main strategies that authors have adopted so far. On the one hand, there is research aimed at characterizing a specific content, which should account for conscious states. We may call this the content approach. On the other hand, one finds the processing approach, which proposes to look for a particular way of processing to account for consciousness.. Our aim, in this paper, is (...) to develop arguments for the latter approach. We focus on a criticism of Jesse Prinz’s AIR theory of consciousness. We have chosen Prinz’s theory because it incorporates features of both the content and processing approaches, and discussing it will therefore allow us to compare the advantages and downsides of both. Our argument will focus in particular on the notion of intermediate-level. We will discuss how Prinz characterizes the intermediate-level according to a content approach, and argue that such a characterization is inadequate. Finally, we will argue in favor of processing approach to the problem of consciousness, which also accounts for the massive interaction of top-down and bottom-up processes in the brain. Even though consciousness remains an unsolved riddle, we claim that this is the best path towards a solution. (shrink)

I defend the actualist higher-order thought theory against four objections. The first objection contends that the theory is circular. The second one contends that the theory is unable to account for the alleged epistemic position we are in with respect to our own conscious mental states. The third one contends that the theory is unable to account for the evidence we have for the proposition that all conscious mental states are represented. The fourth one contends that the theory does not (...) accommodate the intimacy we have with our own conscious mental states. To some extent, my defense will be heterodox, in the sense that I will show that some objections are satisfactorily answerable even if we concede to the objectors a point that higher-order theorists do not seem to be willing to concede, that is, that the theory is the result of conceptual analysis.

Many have urged that the biggest obstacles to a physicalistic understanding of consciousness are the problems raised in connection with the subjectivity of consciousness. These problems are most acutely expressed in consideration of the knowledge argument against physicalism. I develop a novel account of the subjectivity of consciousness by explicating the ways in which mental representations may be perspectival. Crucial features of my account involve analogies between the representations involved in sensory experience and the ways in which pictorial representations exhibit (...) perspectives or points of view. I argue that the resultant account of subjectivity provides a basis for the strongest response physicalists can give to the knowledge argument. (shrink)

P/A (Block's phenomenal/access) confounds a logical distinction with an empirical claim. Success of P/A in its logical role has almost no bearing on its plausibility as an empirical thesis (i.e., that two kinds of consciousness exist). The advantage of P/A over a single-consciousness assumption is unclear, but one of Block's analogies for P (liquid in a hydraulic computer) may be used to clarify the notion of consciousness as cognitive “hardware.”.

Philosophers, especially in recent years, have engaged in reflection upon the nature of experience. Such reflections have led them to draw a distinction between conscious and unconscious mentality in terms of whether or not it is like something to have a mental state. Reflection upon the history of psychology and upon contemporary cognitive science, however, identifies the distinction between conscious and unconscious mental states to be primarily one which is drawn in epistemic terms. Consciousness is an epistemic notion marking the (...) special kind of first-person knowledge we have of our own mental states. Psychologists have found it expedient, for explanatory reasons, to ignore or reject the assumption that we have exhaustive first-person knowledge of our mental states and, in doing so, use the term ‘unconscious’ to indicate the peculiar epistemic status of certain mental states.It is argued that epistemic consciousness is distinct from the subjective-experiential notion of consciousness, from ‘access-consciousness’ and from higher-order thought conceptions of mental state consciousness, and that epistemic consciousness has an important role to play in philosophy of mind and in the history of psychology.Author Keywords: Consciousness; Unconscious mental states; Self-knowledge; History of psychology; Freud; Chomsky.

According to Armstrong (amongst others) ‘any truth, should depend for its truth for something “outside” it’ where this one-way dependency is explained in terms of the asymmetric relationship that obtains between a truth and its truth-maker. But there’s no need to appeal to truth-makers to make sense of this dependency. The truth of a proposition is essentially determined by the interlocking semantic mechanism of reference and satisfaction which already ensures that the truth-value of a proposition depends on how things stand (...) outside it. By contrast, how things stand outside of a proposition is determined by other worldly mechanisms that have nothing to do with truth. (shrink)

Many recent discussions of self-consciousness and self-knowledge assume that there are only two kinds of accounts available to be taken on the relation between the so-called first-order (conscious) states and subjects' awareness or knowledge of them: a same-order, or reflexive view, on the one hand, or a higher-order one, on the other. I maintain that there is a third kind of view that is distinctively different from these two options. The view is important because it can accommodate and make intelligible (...) certain cases of authoritative self-knowledge that cannot easily be made intelligible, if at all, by these other two types of accounts. My aim in this paper is to defend this view against those who maintain that a same-order view is sufficient to account for authoritative self-knowledge. (shrink)

Block contends that the concept of consciousness is a mongrel concept and that researchers go astray by conflating different notions of “consciousness.” This is certainly true. In fact, it is truer than Block acknowledges, because his own notion of P-consciousness runs together two, or arguably three, quite different and separable features of a sensory state.

The information processing that constitutes accessconsciousness is not sufficient to make a representational state conscious in any sense. Standard examples of computation without consciousness undermine A-consciousness, and Block's cases seem to derive their plausibility from a lurking phenomenal awareness. That is, people and other minded systems seem to have access-consciousness only insofar as the state accessed is a phenomenal one, or the state resulting from access is phenomenal, or both.

Basically agreeing with Block regarding the need for a distinction between P- and A-consciousness, I characterize the problem somewhat diflerently, relating it more directly to the explanatory gap. I also speculate on the relation between the two forms of consciousness, arguing that some notion of access is essentially involved in phenomenal experience.

Shoemaker argues that a satisfactory resolution of Moore's paradox requires a _self-intimation thesis that posits a "constitutive relation between belief and believing that one believes." He claims that such a thesis is needed to explain the crucial fact that the assent conditions for '_P' entail those for '_I believe that P'. This paper argues for an alternative resolution of Moore's paradox that provides for an adequate explanation of the crucial fact without relying on the kind of necessary connection between first (...) and second-order beliefs that is posited by Shoemaker's self-intimation thesis.

Currently, one of the most influential theories of consciousness is Rosenthal's version of higher-order-thought (HOT). We argue that the HOT theory allows for two distinct interpretations: a one-component and a two-component view. We further argue that the two-component view is more consistent with his effort to promote HOT as an explanatory theory suitable for application to the empirical sciences. Unfortunately, the two-component view seems incapable of handling a group of counterexamples that we refer to as cases of radical confabulation. We (...) begin by introducing the HOT theory and by indicating why we believe it is open to distinct interpretations. We then proceed to show that it is incapable of handling cases of radical confabulation. Finally, in the course of considering various possible responses to our position, we show that adoption of a disjunctive strategy, one that would countenance both one-component and two-component versions, would fail to provide any empirical or explanatory advantage.

We consider consciousness attributed to systems in space-time which can be purely physical without biological background and focus on the mathematical understanding of the phenomenon. It is shown that the set theory based on sets in the foundations of mathematics, when switched to set theory based on ZFC models, is a very promising mathematical tool in explaining the brain/mind complex and the emergence of consciousness in natural and artificial systems. We formalise consciousness-supporting systems in physical space-time, but this is localised (...) in open domains of spatial regions and the result of this process is a family of different ZFC models. Random forcing, as in set theory, corresponds precisely to the random influence on the system of external stimuli, and the principles of reflection of set theory explain the conscious internal reaction of the system. We also develop the conscious Turing machines which have their external ZFC environment and the dynamics is encoded in the random forcing changing models of ZFC in which Turing machines with oracles are formulated. The construction is applied to cooperating families of conscious agents which, due to the reflection principle, can be reduced to the implementation of certain concurrent games with different levels of self-reflection.

In this paper, a theoretical account of the functional role of consciousness in the cognitive system of normal subjects is developed. The account is based upon an approach to consciousness that is drawn from the phenomenological tradition. On this approach, consciousness is essentially peripheral self-awareness, in a sense to be duly explained. It will be argued that the functional role of consciousness, so construed, is to provide the subject with just enough information about her ongoing experience to make it possible (...) for her to easily obtain as much information as she may need. The argument for this account of consciousness' functional role will proceed in three main stages. First, the phenomenological approach to consciousness as peripheral self-awareness will be expounded and endorsed. Second, an account of the functional role of peripheral perceptual awareness will be offered. Finally, the account of the functional role of peripheral self-awareness will be obtained by straightforward extension from the functional role of peripheral perceptual awareness. (shrink)

. When I have a conscious experience of the sky, there is a bluish way it is like for me to have that experience. We may distinguish two aspects of this "bluish way it is like for me": the bluish aspect and the for-me aspect. Let us call the bluish aspect of the experience its qualitative character and the for-me aspect its subjective character . What is this elusive for-me-ness, or subjective character , of conscious experience? In this paper, I (...) examine six different attempts to account for subjective character in terms of the functional and representational properties of conscious experiences. After arguing against the first five, I defend the sixth. (shrink)

Propositions such as are paradoxical, in that even though they can be true, they cannot be truly asserted or believed. This is Moore’s paradox. Sydney Shoemaker has recently ar- gued that the paradox arises from a constitutive relation that holds between first- and second-order beliefs. This paper explores this approach to the paradox. Although Shoemaker’s own account of the paradox is rejected, a different account along similar lines is endorsed. At the core of the endorsed account is the claim that (...) conscious beliefs are always partly about themselves; it will be shown to follow from this that conscious beliefs in Moorean propositions are self-contradictory.

It is often assumed thatconsciousness and intentionality are twomutually independent aspects of mental life.When the assumption is denounced, it usuallygives way to the claim that consciousness issomehow dependent upon intentionality. Thepossibility that intentionality may bedependent upon consciousness is rarelyentertained. Recently, however, John Searle andColin McGinn have argued for just suchdependence. In this paper, I reconstruct andevaluate their argumentation. I am in sympathyboth with their view and with the lines ofargument they employ in its defense. UnlikeSearle and McGinn, however, I am (...) quite attachedto a naturalist approach to intentionality. Itwill turn out to be somewhat difficult toreconcile naturalism with the notion thatintentionality is dependent upon consciousness,although, perhaps surprisingly, I will arguethat McGinn's case for such dependence iscompatible with naturalism.

Phenomenal consciousness is the property mental states, events, and processes have when, and only when, there is something it is like for their subject to undergo them, or be in them. What it is like to have a conscious experience is customarily referred to as the experience’s phenomenal character. Theories of consciousness attempt to account for this phenomenal character. This article surveys the currently prominent theories, paying special attention to the various attempts to explain a state’s phenomenal character in terms (...) of its representational content.

RÉSUMÉ: Les discussions philosophiques actuelles sur le problème de la conscience [consciousness] se concentrent sur la question des qualia, ou qualités sensorielles. Mais les auteurs traditionnels au sujet de la conscience—tels que Kant et William James—s'intéressaient davantage à un autre aspect de l'expérience consciente, à savoir le fait que lorsqu'on est conscient [conscious], on est en même temps, et de façon permanente, conscient de soi-même [aware of oneself] comme sujet de l'expérience. Cet article explore trois modèles représentationnels du phénomène de (...) la conscience permanente de soi [permanent self-awareness]. Chacun d'eux se révèle inadéquat pour une raison ou pour une autre. Ce que la discussion fait ainsi ressortir, c'est le genre d'exigences auxquels devrait satisfaire une bonne théorie de la conscience permanente de soi. (shrink)
