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

For patients under anesthesia, it is extremely important to be able to ascertain from a scientific, third person point of view to what extent consciousness is correlated with specific areas of brain activity. Errors in accurately determining when a patient is having conscious states, such as conscious perceptions or pains, can have catastrophic results. Here, I argue that the effects of (at least some kinds of) anesthesia lend support to the notion that neither basic sensory areas nor the prefrontal cortex (...) (PFC) is sufficient to produce conscious states. I also argue that it this is consistent with and supportive of the higher-order thought (HOT) theory of consciousness. I therefore disagree in some ways with Mehta and Mashour (2013), who argue that evidence from anesthesia mainly favors a first-order representational (FOR) theory, as opposed to HOT theory (and many other theories, for that matter).

What is it that makes a mental state conscious? Recent commentators have proposed that for Kant, consciousness results from differentiation: A mental state is conscious insofar as it is distinguished, by means of our conceptual capacities, from other states and/or things. I argue instead that Kant’s conception of state consciousness is sensory: A mental state is conscious insofar as it is accompanied by an inner sensation. Interpreting state consciousness as inner sensation reveals an underappreciated influence of Crusius on Kant’s view, (...) solves some long-standing puzzles concerning Kant’s difficult doctrine of self-affection, and sheds light on his theory of inner experience.

Many philosophers and scientists have argued that the difference between phenomenally conscious states and other kind of states lies in the implicit self-awareness that conscious states have. Higher-Order Representationalist theories, attempt to explain such a self-awareness by means of a higher-order representation. Consciousness relies on our capacity to represent our own mental states, consciousness depends on our Theory of Mind. Such an ability can, at least conceptually, be decomposed into another two: mindreading and metacognition. In this paper I will argue (...) that consciousness cannot depend on mindreading. The tenability of HOR theories depends, therefore, on the relation between mindreading and metacognition. I analyze several views on such a relation and argue that none of them seem to be a plausible option for HOR theories. (shrink)

There has been much discussion about the nature and even existence of so-called “pure conscious events” (PCEs). PCEs are often described as mental events which are non-conceptual and lacking all experiential content (Forman 1990). For a variety of reasons, a number of authors have questioned both the accuracy of such a characterization and even the very existence of PCEs (Katz 1978, Bagger 1999). In this chapter, I take a somewhat different, but also critical, approach to the nature and possibility of (...) PCEs. I focus on several overlapping views found in recent analytic philosophy of mind and examine PCEs in light of them. After introducing terminology and some preliminary matters, I examine whether or not the “higher-order thought (HOT) theory of consciousness” rules out the possibility of PCEs, and conversely, whether or not PCEs show that the HOT theory cannot apply to all conscious states. The HOT theory says that what makes a mental state conscious is that it is accompanied by a higher-order thought to the effect that “I am in mental state M now.” A related theme will be to assess PCEs in light of the recent debate between so-called “conceptualists” and those who believe that there are “non-conceptual contents of experience.” Conceptualism, to which I am very sympathetic, is basically the view that all conscious experience is structured by concepts possessed by the subject. I argue that PCEs are indeed conceptual and so no threat to conceptualism. For example, standard criticisms of conceptualism do not apply to PCEs. Finally, I examine the possibility that PCEs are not conscious at all. In the end, my overall conclusion is that we should hold that PCEs are indeed compatible with both HOT theory and conceptualism or seriously question the idea that PCEs are conscious at all.

In this paper, I argue against the claim recently defended by Josh Weisberg that a certain version of the self-representational approach to phenomenal consciousness cannot avoid a set of problems that have plagued higher-order approaches. These problems arise specifically for theories that allow for higher-order misrepresentation or—in the domain of self-representational theories—self-misrepresentation. In response to Weisberg, I articulate a self-representational theory of phenomenal consciousness according to which it is contingently impossible for self-representations tokened in the context of a conscious mental (...) state to misrepresent their objects. This contingent infallibility allows the theory to both acknowledge the (logical) possibility of self-misrepresentation and avoid the problems of self-misrepresentation. Expanding further on Weisberg’s work, I consider and reveal the shortcomings of three other self-representational models—put forward by Kreigel, Van Gulick, and Gennaro—in order to show that each indicates the need for this sort of infallibility. I then argue that contingent infallibility is in principle acceptable on naturalistic grounds only if we attribute (1) a neo-Fregean kind of directly referring, indexical content to self-representational mental states and (2) a certain ontological structure to the complex conscious mental states of which these indexical self-representations are a part. In these sections I draw on ideas from the work of Perry and Kaplan to articulate the context-dependent semantic structure of inner-representational states. (shrink)

It is often said that some kind of peripheral (or inattentional) conscious awareness accompanies our focal (attentional) consciousness. I agree that this is often the case, but clarity is needed on several fronts. In this paper, I lay out four distinct theses on peripheral awareness and show that three of them are true. However, I then argue that a fourth thesis, commonly associated with the so-called "self-representational approach to consciousness," is false. The claim here is that we have outer focal (...) consciousness accompanied often (or even always) by inner peripheral (self-)awareness. My criticisms stem from both methodological and phenomenological considerations. In doing so, I offer a diagnosis as to why the fourth thesis has seemed true to so many and also show how the so-called "transparency of experience," frequently invoked by representationalists, is importantly relevant to my diagnosis. Finally, I respond to several objections and to further attempts to show that thesis four is true. What emerges is that if one wishes to hold that some form of self-awareness accompanies all outer-directed conscious states, one is better off holding that such self-awareness is itself unconscious, as is held for example by standard higher-order theories of consciousness.

One of the promising approaches to the problem of consciousness has been the Higher-Order Monitoring Theory of Consciousness. According to the Higher-Order Monitoring Theory, a mental state M of a subject S is conscious iff S has another mental state, M*, such that M* is an appropriate representation of M. Recently, several philosophers have developed a Higher-Order Monitoring theory with a twist. The twist is that M and M* are construed as entertaining some kind of constitutive relation, rather than being (...) logically independent of each other. We may call this the Same-Order Monitoring Theory of Consciousness. In this paper, I discuss the nature of the Same-Order Monitoring Theory and argue for its superiority over the more traditional Higher-Order Monitoring Theory. (shrink)

This paper presents a new cognitivist account for the old puzzle of self-consciousness or knowing self-reference. Knowing self-reference does not rely on reflection on some putative pre-existent pre-reflexive self-consciousness, nor is it the result of a process of identification of oneself as the employer of the relevant token of “I” according to the token-reflexive rule of the first-person pronoun. Rather, it relies on the architecture of the cognitive system. By exploiting the acquaintance relation that every brain has to one’s own (...) body, a “mental file” is opened in a subliminal way to house information about oneself gained through the appropriate proprioceptors. Knowing self-reference based on self-files dispenses with self-identification because the opening of the file in the same brain/body is not a deed of the cognitive system but rather something that takes place sub-personally.

How does one know the phenomenal character of one’s own experience? I aim to present and defend a new view of the epistemology of qualia that addresses this issue. My view results from a reworking of Dretske’s displaced perception model. The guiding line is the key Wittgensteinian insight of his Private Language Argument, namely the claim that no inner perception of qualia can justify our corresponding qualia beliefs. My reworking of the original model starts with the rejection of Dretske’s representationalism, (...) as well as any other metaphysical views about the ultimate nature of qualia. The reworking of the displaced perception model I am proposing is supposed to be compatible with any available metaphysical view on qualia. The second step consists of rejecting the epistemological misgivings of the original model, namely the view that knowing qualia requires “connecting beliefs” along with “meta-representations.” Yet, Dretske’s crucial mistake has been to force knowledge of qualia into the “belief-box.” As a matter of fact, there is only one belief involved in introspecting qualia, namely the qualia-belief itself. The third final step is this. Assuming the key Wittgensteinian insight, I argue that introspection of qualia is a process that is both epis- temically reliable and automatic. It is reliable because it dispenses with justification of any beliefs whatsoever. Moreover, it is automatic because it also dispenses with reflexive connecting beliefs. For example, it takes nonconceptual awareness of the color blue as an input and automatically yields the belief that phenomenal blue is the conscious character of my experience of the sky as an output just by employing the concept BLUE.

Success semantics holds, roughly, that what it is for a state of an agent to be a belief that P is for it to be disposed to combine with her desires to cause behaviour that would fulfill those desires if P. J. T. Whyte supplements this with an account of the contents of an agent's “basic desires” to provide an attractive naturalistic theory of mental content. We argue that Whyte's strategy can avoid the objections raised against it by restricting “basic (...) desires” to sensory inclinations that cause us to do things independently of our beliefs about their contents. -/- La sémantique du succès soutient, en gros, que ce qu'il faut pour qu'un état d'un agent soit une croyance en P, c'est que cet état soit disposé à se combiner avec ses désirs pour provoquer un comportement qui répondrait à ces désirs si P. J. T. Whyte complète cela par un compte-rendu du contenu des « désirs de base » d'un agent pour fournir une théorie naturaliste attrayante du contenu mental. Nous soutenons que la stratégie de Whyte peut éviter les objections qui lui sont faites en restreignant les « désirs de base » aux inclinations sensorielles qui nous font agir indépendamment de nos croyances sur leur contenu.

In recent years, there has been an increasing interest among philosophers of memory in the questions of how to characterize and to account for the temporal phenomenology of episodic memory. One prominent suggestion has been that episodic memory involves a feeling of pastness, the elaboration of which has given rise to two main approaches. On the intentionalist approach, the feeling of pastness is explained in terms of what episodic memory represents. In particular, Fernández has argued that it can be explained (...) in terms of memory representing itself as being caused by a past perceptual experience. On the metacognitive approach, which we have recently developed in, the feeling of pastness results from the monitoring and interpretation of the processing features of episodic remembering. In this paper, we show that the metacognitive approach should be preferred over the intentionalist approach. We argue that intentionalism, and Fernández’ causal self-referential view in particular, ultimately fail as accounts of the feeling of pastness. The difficulties faced by intentionalism allows us to single out three constraints that any satisfactory account of the temporal phenomenology of episodic remembering needs to meet. We conclude by arguing that the metacognitive view satisfies those constraints in a neat way, and as such, that it should be preferred over intentionalism. (shrink)

Several influential philosophers and scientists have advanced a framework, often called Neo-Cartesianism (NC), according to which animal suffering is merely apparent. Drawing upon contemporary neuroscience and philosophy of mind, Neo-Cartesians challenge the mainstream position we shall call Evolutionary Continuity (EC), the view that humans are on a nonhierarchical continuum with other species and are thus not likely to be unique in consciously experiencing negative pain affect. We argue that some Neo-Cartesians have misconstrued the underlying science or tendentiously appropriated controversial views (...) in the philosophy of mind. We discuss recent evidence that undermines the simple neuroanatomical structure-function correlation thesis that undergirds many Neo-Cartesian arguments, has an important bearing on the recent controversy over pain in fish, and places the underlying epistemology framing the debate between NC and EC in a new light that strengthens the EC position.

In response to Fred Adams and Charlotte Shreve’s (2016) paper entitled “What Can Synesthesia Teach Us about Higher Order Theories of Consciousness?”, previously published in Symposion, I argue that H.O.T. theory does have the resources to account for synesthesia and the specific worries that they advance in their paper, such as the relationship between concepts and experience and the ability to handle instances of ‘pop-out’ experiences.

This thesis introduces the Problem of Consciousness as an antinomy between Physicalism and Primitivism about the phenomenal. I argue that Primitivism is implausible, but is supported by two conceptual gaps. The ‘–tivity gap’ holds that physical states are objective and phenomenal states are subjective, and that there is no entailment from the objective to the subjective. The ‘–trinsicality gap’ holds that physical properties are extrinsic and phenomenal qualities are intrinsic, and that there is no entailment from the extrinsic to the (...) intrinsic. Stoljar’s Epistemic View (EV) suggests that we have a limited conception of the physical world, and that the apparent inexplicability of consciousness is merely a symptom of our ignorance. I argue that EV must satisfy two conditions which require it to specify the content of our ignorance. EV’s best hope is a Russellian appeal to our ignorance of intrinsic physical properties. After arguing in favour of this ignorance claim, I show how it undermines the –trinsicality gap. However, I suggest that the –tivity gap cannot be dealt with by the Russellian ignorance hypothesis, nor by any other version of EV. However, I then argue that the Russellian ignorance hypothesis can still be deployed as half of a hybrid account of the phenomenal. Representationalist theories of consciousness have difficulty with the –trinsicality gap, but show promise with the –tivity gap. Specifically, Kriegel’s Self-Representationalism indicates that there can indeed be an entailment from objective physical states to subjective phenomenal states. This paves the way for my hybrid account of consciousness: the subjectivity of a phenomenal state is the product of its self-representational structure, and the qualitative character of a phenomenal state is the product of the epistemically inaccessible intrinsic physical properties involved in its implementation.

This thesis examines the relation between self-deception and self-consciousness. It has been argued that, if we follow the literalist and take self-deception at face value – as a deception that is intended by, and imposed on, one and the same self-conscious subject – then self-deception is impossible. It will incur the Dynamic Problem that, being aware of my intention to self-deceive, I shall see through my projected self-deceit from the outset, thereby precluding its possibility. And it will incur the following (...) Static Problem. Qua self-deceiver, I shall believe not-P, but – qua self-deceived – I shall believe P. We shall then have to explain how I can sustain contradictory beliefs in full self-awareness. I argue that this rejection of literalism about self-deception rests on error. First, it misunderstands what literalism holds. Properly understood, literalism does not require the simultaneous commitment to contradictory beliefs. Second, it misunderstands the relation between self-deception and self-consciousness – and that is my primary focus. The phenomenology of self-deception reveals that the self-deceiver experiences the following tension. She is somehow aware of her self-deception as such. Yet also, she misrepresents that self-deception to herself as being a sincere commitment to the truth – so, in that sense, she is not aware of her self-deceit as such. To capture this tension, we require a theory of self-consciousness – independently defensible in its own right – that will meet this twofold requirement, of permitting the self-deceiver not to see what is right before her gaze. The rejection of literalism presupposes that no theory of self-consciousness can meet this twofold requirement.I argue that this twofold requirement can be met. The first part of this thesis offers a detailed defence of a theory of self-consciousness. The second part shows how this theory of self-consciousness can faithfully capture the tension of self-deception, while eschewing the Dynamic and Static Problems. It thereby claims to vindicate the literalist's position. (shrink)

The same-order representation theory of consciousness holds that conscious mental states represent both the world and themselves. This complex representational structure is posited in part to avoid a powerful objection to the more traditional higher-order representation theory of consciousness. The objection contends that the higher-order theory fails to account for the intimate relationship that holds between conscious states and our awareness of them--the theory 'divides the phenomenal labor' in an illicit fashion. This 'failure of intimacy' is exposed by the possibility (...) of misrepresentation by higher-order states. In this paper, I argue that despite appearances, the same-order theory fails to avoid the objection, and thus also has troubles with intimacy. (shrink)

Due to their reliance on constitutive higher-order representing to generate the qualities of which the subject is consciously aware, I argue that the major existing higher-order representational theories of consciousness insulate us from our first-order sensory states. In fact on these views we are never properly conscious of our sensory states at all. In their place I offer a new higher-order theory of consciousness, with a view to making us suitably intimate with our sensory states in experience. This theory relies (...) on the idea of ‘quoting’ sensory qualities, so is dubbed the ‘quotational higher-order thought theory’. I argue that it can capture something of the idea that we are ‘acquainted’ with our conscious states without slipping beyond the pale for naturalists, whilst also providing satisfying treatments of traditional problems for higher-order theories concerning representational mismatch. The theory achieves this by abandoning a representational mechanism for mental intentionality, in favour of one based on ‘embedding’. (shrink)

ABSTRCT: In this commentary, I criticize Metzinger's interdisciplinary approach to fixing the explanandum of a theory of consciousness and I offer a commonsense alternative in its place. I then re-evaluate Metzinger's multi-faceted working concept of consciousness, and argue for a shift away from the notion of "global availability" and towards the notio ns of "perspectivalness" and "transparency." This serves to highlight the role of Metzinger's "phenomenal model of the intentionality relation" (PMIR) in explaining consciousness, and it helps to locate Metzinger's (...) theory in relation to other naturalistic theories of.

This dissertation consists of three independent papers, each defending the Higher-Order Thought (HOT) Theory of Consciousness against a different objection. First the HOT theory is defended against the Theory of Mind (TOM) Objection. Since the HOT theory requires that a subject be able to represent mental states in thought in order to have mental states that are conscious, objectors argue from empirical evidence that few creatures pass TOM tests to the conclusion that few creatures must be capable of having conscious (...) mental states according to the HOT theory. The counter-intuitiveness of this claim is then taken as reason for rejecting the HOT theory. I argue that this objection is based on a false assumption - that the requirements of successful TOM test performance parallel the requirements outlined by the HOT theory. Since this assumption is false, we can reject the objection. In the second paper, I defend the HOT theory against the Phenomenal Character Argument. Objectors argue that the HOT theory must be rejected because it incorrectly characterizes the phenomenal character affiliated with basic state consciousness as necessarily involving a consciousness of the fact that one has a particular mental state. I argue that the theory cannot provide this characterization of phenomenal character because the theory cannot say that someone becomes conscious of what her unconscious HOTs represent. Since the objection rests on an incorrect interpretation of the theory, we can reject the objection. In the final paper, I defend the HOT theory against the Misrepresentation Objection. Here objectors accuse the HOT theory of presenting necessary and sufficient conditions for conscious states that turn out to be incompatible in empty HOT cases (cases wherein one’s HOT misrepresents the states one is instantiating). I argue that the conditions are actually each part of separate explanations of separate sorts of consciousness, that neither of the separate explanations has internally incompatible conditions, and hence that the objection is based on an equivocation on two senses of the phrase ‘conscious state’. Since the objection is based on this error, we can reject the objection. (shrink)

In this paper I aim to defend David Rosenthal's higher-order thought theory of consciousness against a prominent objection. The central claim of HOT theory is that a mental state is conscious only if one has the HOT that one is in that state. In broad outline, the objection is that HOT theory is unable to account for cases where the relevant HOTs are false. I consider two variants of the objection, corresponding to two kinds of false HOT: those that merely (...) misrepresent their targets, and those which lack targets altogether. I argue that a satisfactory response to the objection involving the latter, targetless, kind of HOTs, is to deny that one is in any conscious state in virtue of such HOTs. I show how this response is superior to Rosenthal's own response, and defend it against objections. I also argue that my account of targetless HOT cases may be generalized to cover cases of misrepresenting HOTs. (shrink)

According to Uriah Kriegel’s self-representational theory of consciousness, mental state M is conscious just in case it is a complex with suitably integrated proper parts, M 1 and M 2, such that M 1 is a higher-order representation of lower-order representation M 2. Kriegel claims that M thereby “indirectly” represents itself, and he attempts to motivate this claim by appealing to what he regards as intuitive cases of indirect perceptual and pictorial representation. For example, Kriegel claims that it’s natural to (...) say that in directly perceiving the front surface of an apple one thereby perceives the apple itself. Cases such as this are supposed to provide intuitive support for the principle that if X represents Y, and Y is highly integrated into complex object Z, then X indirectly represents Z. In this paper I provide counterexamples to Kriegel’s principle of indirect representation, before going on to argue that we can explain what is going on in those cases in which the subject seems to represent a complex whole by representing one its parts without positing indirect representations anyway. I then argue that my alternative approach is superior to Kriegel’s in a number of ways, thereby rendering his theory of consciousness implausible. (shrink)

Monitoring approaches to consciousness claim that a mental state is conscious when it is suitably monitored. Higher-order monitoring theory makes the monitoring state and the monitored state logically independent. Same-order monitoring theory claims a constitutive, non-contingent connection between the monitoring state and the monitored state. In this paper, I articulate different versions of the same-order monitoring theory and argue for its supremacy over the higher-order monitoring theory.

Higher Order theories of consciousness have their fair share of sympathisers, but the arguments mustered in their support are—to my mind—unduly persuasive. My aim in this paper is to show that Higher Order theories cannot accommodate the possibility of misrepresentation without either falling into contradiction, or collapsing into a First-Order theory. If this diagnosis is on the right track, then Higher Order theories—at least in the specific versions here considered—fail to give an account of what they set out to explain: (...) what is distinctive of ‘conscious’ phenomena.

This is a fine and important collection of eleven recently published essays by Peter Carruthers, a leading figure in contemporary philosophy of mind. The book contains a very helpful introduction that provides a nice overview of Carruthers’ basic views and orients the reader to the key issues. The introduction also presents a brief summary of the eleven chapters that comprise the remainder of the book. Only three of the essays initially appeared prior to Carruthers’ important 2000 book Phenomenal Consciousness: A (...) Naturalistic Theory. One of these is significantly rewritten: an essay entitled “Natural Theories of Consciousness,” which will be familiar to readers of Psyche since it was the subject of a symposium in volumes 4-6. There is also one entirely new essay entitled “Dual-Content Theory: the Explanatory Advantages”. Thus, there is much to learn about Carruthers’ theory of consciousness even for those very familiar with his 2000 book. Indeed, one might think of this collection as elaborating upon Carruthers’ views as found in his earlier book. In the relatively short period of a few years, Carruthers has managed to publish an impressive number of quality essays, which comprise most of this anthology. It is very convenient to have these nicely written essays all in one place. For those unfamiliar with Phenomenal Consciousness, this book is still readable on its own and contains many helpful summaries of Carruthers’ earlier work. (shrink)

Within the philosophy of mind, consciousness is currently understood as the expression of one or other cognitive modality, either intentionality , transparency , subjectivity or reflexivity . However, neither intentionality, subjectivity nor transparency adequately distinguishes conscious from nonconscious cognition. Consequently, the only genuine index or defining characteristic of consciousness is reflexivity, the capacity for autonoetic or self-referring, self-monitoring awareness. But the identification of reflexivity as the principal index of consciousness raises a major challenge in relation to the cognitive mechanism responsible (...) for operationalizing such a reflexive state. Current reliance by higher-order and intrinsic self-representational theories on self-representing data structures to achieve reflexive self-awareness is highly problematic, suggesting a solution in terms of a self-referential processing regime.
