Illusionism is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Many opponents to the thesis take it to be obviously false. They think that they can reject illusionism, even if they conceded that it is coherent and supported by strong arguments. David Chalmers has articulated this reaction to illusionism in terms of a “Moorean” argument against illusionism. This argument contends that illusionism is false, because it is obviously true that we have phenomenal experiences. I argue (...) that this argument fails by showing that its defenders cannot maintain that its crucial premise has the kind of support needed for the argument to work, without begging the question against illusionism.

Illusionists claim that phenomenal consciousness does not exist, but merely seems to exist. Most debates concerning illusionism focus on whether or not it is true—whether phenomenal consciousness really is an illusion. Here I want to tackle a different question: assuming illusionism is true, what kind of illusion is the illusion of phenomenality? Is it a “rich” illusion—the cognitively impenetrable activation of an incorrect representation—or a “sparse” illusion—the cognitively impenetrable activation of an incomplete representation, which leads to drawing incorrect judgments? I (...) present this distinction and I classify the most influential illusionist theories along this line of divide. I then offer an argument against the accounts of the illusion of phenomenality in terms of sparse illusion. (shrink)

Why do we tend to think that phenomenal consciousness poses a hard problem? The answer seems to lie in part in the fact that we have the impression that phenomenal experiences are presented to us in a particularly immediate and revelatory way: we have a sense of acquaintance with our experiences. Recent views have offered resources to explain such persisting impression, by hypothesizing that the very design of our cognitive systems inevitably leads us to hold beliefs about our own experiences (...) with certainty. I argue against this kind of “designed certainty” views. First, I claim that it is doubtful that we really hold beliefs about our own experiences with certainty—in any sense of certainty that would make our phenomenal beliefs special. Second, I claim that, even if it were the case that we hold beliefs about experiences with certainty, this would fall short of explaining our sense of acquaintance. (shrink)

Recent philosophy has seen a resurgence of the realist view of sensible qualities such as colour. The view holds that experienced qualities are properties of the objects in the physical environment, not mentally instantiated properties like qualia or merely intentional, illusory ones. Some suggest that this move rids us of the explanatory gap between physical properties and the qualitative features of consciousness. Others say it just relocates the problem of qualities to physical objects in the environment, given that such qualities (...) cannot be derived from the non-qualitative properties of objects, and it does not resolve the problem of consciousness either. I argue that such an outcome is welcome: if the physical world is full of explanatory gaps, then the mind–body explanatory gap is not so special. Moreover, the explanatory gaps regarding qualities of objects are less puzzling than the brain-qualia gap. In order to counter the usual worries concerning realism about objective qualities, I introduce ‘imperfect realism’ as an alternative to colour pluralism and complex reductionism, which accommodates realism in the face of widespread perceptual error. I conclude with a discussion of how this ‘multiple-gaps view’ sits better with a naturalistic framework compared to the Galilean-Cartesian account of qualities. (shrink)

There’s a long but relatively neglected tradition of attempting to explain why many researchers working on the nature of phenomenal consciousness think that it’s hard to explain.1 David Chalmers argues that this “meta-problem of consciousness” merits more attention than it has received. He also argues against several existing explanations of why we find consciousness hard to explain. Like Chalmers, we agree that the meta-problem is worthy of more attention. Contra Chalmers, however, we argue that there’s an existing explanation that is (...) more promising than his objections suggest. We argue that researchers find phenomenal consciousness hard to explain because phenomenal concepts are complex demonstratives that encode the impossibility of explaining consciousness as one of their application conditions. (shrink)

The search for the neural correlates of consciousness is in need of a systematic, principled foundation that can endow putative neural correlates with greater predictive and explanatory value. Here, we propose the predictive processing framework for brain function as a promising candidate for providing this systematic foundation. The proposal is motivated by that framework’s ability to address three general challenges to identifying the neural correlates of consciousness, and to satisfy two constraints common to many theories of consciousness. Implementing the search (...) for neural correlates of consciousness through the lens of predictive processing delivers strong potential for predictive and explanatory value through detailed, systematic mappings between neural substrates and phenomenological structure. We conclude that the predictive processing framework, precisely because it at the outset is not itself a theory of consciousness, has significant potential for advancing the neuroscience of consciousness.

The problem of consciousness arises when we depsychologize consciousness—that is, conceptualize it in terms of phenomenal feel rather than psychological function. Panpsychism offers an elegant solution to the problem, which takes depsychologization seriously. In doing so, however, it also illustrates the perils of depsychologization. Nagasawa highlights one dead end for panpsychism, and I shall argue that there are more. Panpsychism consigns consciousness to a metaphysical limbo where it is beyond the reach of science and lacks ethical and personal significance. The (...) moral is that we should retrace our steps and question the depsychologized conception itself. (shrink)

In philosophical thought experiments, as in ordinary discourse, our understanding of verbal case descriptions is enriched by automatic comprehension inferences. Such inferences have us routinely infer what else is also true of the cases described. We consider how such routine inferences from polysemous words can generate zombie intuitions: intuitions that are ‘killed’ (defeated) by contextual information but kept cognitively alive by the psycholinguistic phenomenon of linguistic salience bias. Extending ‘evidentiary’ experimental philosophy, this paper examines whether the ‘zombie argument’ against materialism (...) is built on zombie intuitions. We examine the hypothesis that contextually defeated stereotypical inferences from the noun ‘zombie’ influence intuitions about ‘philosophical zombies’. We document framing effects (‘zombie’ vs ‘duplicate’) predicted by the hypothesis. Findings undermine intuitions about the conceivability of ‘philosophical zombies’ and address the philosophical ‘hard problem of consciousness’. Findings support a deflationary response: The impression that principled obstacles prevent scientific explanation of how physical processes give rise to conscious experience is generated by philosophical arguments that rely on epistemically deficient intuitions. (shrink)

Common arguments for realism about phenomenal consciousness contend that this is a folk concept, with proponents expecting it to be lexicalised in ordinary language. In English, the word ‘experience’ is typically regarded as the best candidate. This predicts that ‘experience’ will be used to refer to mental states and episodes, not only in philosophical but also in ordinary discourse. We conduct a corpus study in order to assess this claim and to understand the actual use of the word in non-academic, (...) academic, and philosophical discourse. In non-academic discourse, uses that refer to knowledge or sources of knowledge, and to public events, are found to dominate. Uses that refer to mental states or episodes dominate only in the philosophy of mind (and not even in philosophy at large). (shrink)

For Advaita Vedānta, consciousness is to be distinguished from all contents of consciousness that might be introspectively detectable: It is precisely consciousness of whatever contents it is conscious of and not itself one of these contents. Its only nature is, Advaita holds, prakāśa ; in itself it is devoid of any content or structure and can never become an object. This paper elaborates on this kind of understanding of consciousness in order to next explain why it might be fruitful for (...) developing a clear understanding of the nature of the so-called problem of consciousness. Today’s philosophy of mind tends to conceive of consciousness in terms of qualia, thereby taking it as a special kind of object. This renders the antimaterialist claim of the distinctness of consciousness from all physical features vulnerable to the materialist reply that the difference in question might be a merely epistemological matter, i.e., a matter of different modes of givenness without difference in what is thus given. This move, however – this paper argues –, is impossible without resulting in circularity or infinite regress with regard to consciousness in the sense of givenness itself. (shrink)

According to an orthodox view, the capacity for conscious experience (sentience) is relevant to the distribution of moral status and value. However, physicalism about consciousness might threaten the normative relevance of sentience. According to the indeterminacy argument, sentience is metaphysically indeterminate while indeterminacy of sentience is incompatible with its normative relevance. According to the introspective argument (by François Kammerer), the unreliability of our conscious introspection undercuts the justification for belief in the normative relevance of consciousness. I defend the normative relevance (...) of sentience against these objections. First, I demonstrate that physicalists only have to concede a limited amount of indeterminacy of sentience. This moderate indeterminacy is in harmony with the role of sentience in determining moral status. Second, I argue that physicalism gives us no reason to expect that introspection is unreliable with respect to the normative relevance of consciousness. (shrink)

Illusionism about consciousness entails that phenomenal consciousness doesn’t exist. The distribution question concerns the distribution of consciousness in the animal kingdom. Skepticism of animal consciousness is the view that few or no kinds of animals possess consciousness. Thus, illusionism seems to imply a skeptical view on the distribution question. However, I argue that illusionism and skepticism of animal consciousness are actually orthogonal to each other. If illusionism is true, then phenomenal consciousness does not ground intrinsic value so that the non-existence (...) of phenomenal consciousness would not have ethical implications. In this case, the adequate reaction is to reformulate the distribution question in terms of the quasi-phenomenal functional features associated with the illusion of phenomenal consciousness which do ground intrinsic value. Hence, either illusionism is false or the distribution question does not concern phenomenal consciousness. In any case, illusionism does not directly tell us anything about the distribution question. However, since illusionism forces us to revise our traditional conception of consciousness, it indirectly affects research on animal consciousness by questioning that consciousness is a unified and an all-or-nothing property.

To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

The proposal that probabilistic inference and unconscious hypothesis testing are central to information processing in the brain has been steadily gaining ground in cognitive neuroscience and associated fields. One popular version of this proposal is the new theoretical framework of predictive processing or prediction error minimization, which couples unconscious hypothesis testing with the idea of ‘active inference’ and claims to offer a unified account of perception and action. Here we will consider one outstanding issue that still looms large at the (...) core of the PEM framework: the lack of a clear criterion for distinguishing conscious states from unconscious ones. In order to fulfill the promise of becoming a unifying framework for describing and modeling cognition, PEM needs to be able to differentiate between conscious and unconscious mental states or processes. We will argue that one currently popular view, that the contents of conscious experience are determined by the ‘winning hypothesis’, falls short of fully accounting for conscious experience. It ignores the possibility that some states of a system can control that system’s behavior even though they are apparently not conscious. What follows from this is that the ‘winning hypothesis’ view does not provide a complete account of the difference between conscious and unconscious states in the probabilistic brain. We show how this problem for the received view can be resolved by augmenting PEM with Daniel Dennett’s multiple drafts model of consciousness. This move is warranted by the similar roles that attention and internal competition play in both the PEM framework and the multiple drafts model. (shrink)

In this paper, the traditional question – what is mind? – is suggested to be treated from the metareflective realist stance from which different determinations of consciousness could be apprehended as always instantiated and dependent on their definitions. Methodological differentiation between what is representational and what is non-representational is expressed as a divergence between particular definitions of consciousness and the ontological X, in this context, acting as a universality of consciousness. The derivation of this position is reached through the investigation (...) of François Laruelle’s non-standard philosophy, Wilfrid Sellars’s critique of the myth of the given and Iain Hamilton Grant’s revisionary study of Schelling’s naturphilosophie.

I argue that it is metaphysically necessary that: (i) every fundamental entity is conscious, and (ii) every fundamental property is a phenomenal property.

In this discussion paper, I argue that no theory of consciousness can simultaneously respect four initially plausible metaphysical claims – namely, “first-person realism”, “non-solipsism”, “non-fragmentation”, and “one world” – but that any three of the four claims are mutually consistent. So, theories of consciousness face a “quadrilemma”. Since it will be hard to achieve a consensus on which of the four claims to retain and which to give up, we arrive at a landscape of competing theories, all of which have (...) pros and cons. I will briefly indicate which kinds of theories correspond to the four horns of the quadrilemma. (shrink)

This dialogue explores the question of whether intentionality—the “ofness”, “aboutness”, or “directedness” of mental states—is a relation. We explore three views: the Naive View, on which intentionality is a relation to ordinary, everyday objects, facts, and other such items; the Abstract Contents View, on which intentionality is a relation to mind-independent abstract entities that are our contents; and the Aspect View, on which intentionality is a matter of having intentional states with particular (non-relational) aspects that are our contents. We consider (...) the challenges facing these views, which include empirical challenges in accounting for all the contents our intentional states can represent, metaphysical challenges in making sense of how contents can be entertained or otherwise represented by us and how they can play a psychological role in the mental economy, and challenges in making sense of how intentionality connects us to the world—if at all. Along the way, we consider the question of how consciousness is related to intentionality and how this affects one’s choice of views. (shrink)

The thesis, typical among dualists, that there are no necessitation relations between events of consciousness and physical events implies that it is prima facie lucky that in our world the apparently existing psychophysical laws usually match events of consciousness and physical events in a “harmonious” way. The lucky psychophysical laws argument concludes that typical dualism amounts to a psychophysical parallelism that is prima facie too improbable to be true. I argue that an anthropic reasoning in the space of possible worlds (...) makes the appearance of a harmonious match situation unsurprising, and that this is all that is needed for the argument to be harmless to a typical dualist.

The Humility Thesis is a persistent thesis in contemporary metaphysics. It is known by a variety of names, including, but not limited to, Humility, Intrinsic Humility, Kantian Humility, Kantian Physicalism, Intrinsic Ignorance, Categorical Ignorance, Irremediable Ignorance, and Noumenalism. According to the thesis, we human beings, and any knowers that share our general ways of knowing, are irremediably ignorant of a certain class of properties that are intrinsic to material entities … Continue reading Humility Regarding Intrinsic Properties →.

The idea of representation has been central in discussions of intentionality for many years. But only more recently has it begun playing a wider role in the philosophy of mind, particularly in theories of consciousness. Indeed, there are now multiple representational theories of consciousness, corresponding to different uses of the term "conscious," each attempting to explain the corresponding phenomenon in terms of representation. More cautiously, each theory attempts to explain its target phenomenon in terms of _intentionality_, and assumes that intentionality (...) is representation. (shrink)

Emergence is a notorious philosophical term of art. A variety of theorists have appropriated it for their purposes ever since George Henry Lewes gave it a philosophical sense in his 1875 Problems of Life and Mind. We might roughly characterize the shared meaning thus: emergent entities (properties or substances) ‘arise’ out of more fundamental entities and yet are ‘novel’ or ‘irreducible’ with respect to them. (For example, it is sometimes said that consciousness is an emergent property of the brain.) Each (...) of the quoted terms is slippery in its own right, and their specifications yield the varied notions of emergence that we discuss below. There has been renewed interest in emergence within discussions of the behavior of complex systems and debates over the reconcilability of mental causation, intentionality, or consciousness with physicalism.

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. After a brief introduction on IIT, we present Chalmers’ original formulation and propose our own Layered View of the Hard Problem, showing how two 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.

This commentary focuses on explaining the intuition of revelation, an issue that Chalmers (2018) raises in his paper. I first sketch how the truth of revelation provides an explanation for the intuition of revelation, and then assess a physicalist proposal to explain the intuition that appeals to Derk Pereboom’s (2011, 2016, 2019) qualitative inaccuracy hypothesis.

David. J. Chalmers examines eleven possible solutions to the meta-problem of consciousness, ‘the problem of explaining why we think that there is a problem of consciousness.’ The present paper argues that Chalmers overlooks an explanation that he has otherwise taken seriously, and which a number of philosophers, physicists, and computer scientists have taken seriously as well: the hypothesis that we are living in a computer simulation. This paper argues that a particular version of the simulation hypothesis is at least as (...) good of a solution to the meta-problem of consciousness as many explanations Chalmers considers, and may even be a better one—as it may be the best solution to a much broader meta-philosophical problem: the ‘meta-problem of everything’, the problem of explaining why our world has the quantum-mechanical, relativistic, and philosophical features it does.

The hard problem of consciousness is the problem of explaining subjective experience. This problem is based on the notion that explaining brain functions cannot lead to explaining experience (Chalmers, 1995). The meta problem of consciousness is the problem that why we think there is a hard problem of consciousness. David Chalmers suggests that solving the meta problem deals with human reports of the hard problem- named problem reports. He notes that since problem reports are facts of human behavior we can (...) consider them explainable by functional terms. Therefore, the meta problem is an easy problem (Chalmers, 2018). In this article, we are trying to to leave open the possibility for hardness of the meta problem. (shrink)

This paper develops a new argument from consciousness to theism: the argument from psychophysical harmony. Roughly, psychophysical harmony consists in the fact that phenomenal states are correlated with physical states and with one another in strikingly fortunate ways. For example, phenomenal states are correlated with behavior and functioning that is justified or rationalized by those very phenomenal states, and phenomenal states are correlated with verbal reports and judgments that are made true by those very phenomenal states. We argue that psychophysical (...) harmony is strong evidence for theism (or, at least, strong evidence against atheism in its standard naturalistic form). (shrink)

In a recent paper in this journal, David Chalmers introduced the meta-problem of consciousness as “the problem of explaining why we think consciousness poses a hard problem” (Chalmers, 2018, p. 6). A solution to the meta-problem could shed light on the hard problem of consciousness. In particular, it would be relevant to elucidate whether people’s problem intuitions (i.e. intuitions holding that conscious experience cannot be reduced to physical processes) are driven by factors related to the nature of consciousness, or rather (...) by factors that are independent of consciousness. Whether people hold problem intuitions, and what factors drive those intuitions, are largely empirical questions. However, there is a lack of empirical research on these issues to date. The results of four studies will show that (1) problem intuitions are not widespread, and (2) when they arise, they do so because of factors that are unrelated to the nature of consciousness. This suggests that consciousness is, after all, not so problematic. (shrink)

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)

Ethicists struggle to take reductive views seriously. They also have trouble conceiving of some supervenience failures. Understanding why provides further evidence for a kind of hybrid view of normative concept use.

The meta-problem of consciousness aims to explain the particularity of our intuitions about consciousness and how they trigger conceptual issues such as the hard problem of consciousness. I propose in this article that these stem from a basic function of the brain : self-evidencing explanation. To make sense of its sensory inputs, the brain is believed to build and test models of the state of the world based on sensory information (Hohwy, 2016). This self-evidencing process has been proposed to describe (...) the type of inference performed by consciousness (Friston, 2018). I will show how this situation is viciously circular and prevents from proving the existence of conscious experience or explaining it without presupposing its existence. I will show how it accounts for the particularity of our intutions about consciousness and thus propose an solution to the meta-problem of consciousness using a formally defined process at the core of conscious inference.

The hard problem of consciousness is the problem of explaining the existence of subjective experience in a world that is purely physical. As the usual theories fail to provide an adequate explanation, many philosophers started looking for alternatives. One of such alternatives is panpsychism, which has been increasingly gaining attention in the past few decades. Panpsychism is the view that fundamental entities of the world—fundamental particles, for example—have some form of very simple consciousness. And, in the theory, it is that (...) spark that allows for the existence of more complex consciousness, such as in humans. However, panpsychism faces a major difficulty with what is called ‘the combination problem’. This is the problem that, even if we accept that fundamental entities have some form of simple consciousness, it is not clear how one could go from a plurality of micro consciousness to a complex unified macro consciousness. If we think that an atom is conscious, for example, this seems to imply that it is a subject, a conscious subject. But how do we get to a human subject, with a complex human brain? It seems difficult to understand how putting together many conscious subjects—e.g. atoms—could lead to a further conscious subject—e.g. a human. In this thesis I discuss panpsychism and some of the arguments that support it. In addition, I explain the combination problem and its different aspects, as well as how it relates to panpsychism and the hard problem of consciousness. Finally, I discuss a solution to the combination problem that I believe has not been given proper attention in contemporary philosophy, which is one provided by the philosopher Ken Wilber. His solution involves changing the conceptual framework of how we understand the relation between macro and micro subjects. I also apply his theory to the variations of the combination problem, discussing how we could approach these issues under a single coherent view. Although Wilber prefers the term pan-interiorism, his theory can be considered a type of holarchical panpsychism. (shrink)

It is often asserted that we should believe that phenomenal consciousness exists because it is pretheoretically obvious. If this is the case, then we should expect lay people to categorize mental states in roughly the way that philosophers do, treating prototypical examples of phenomenally conscious mental states similarly. Sytsma and Machery present preliminary evidence that this is not the case. They found that participants happily ascribed seeing red to a simple robot but denied that the robot felt pain. The most (...) prominent response to this work has been the ambiguity objection, which charges that participants were interpreting ascriptions of seeing red in a purely informational way, such that their attributions of “seeing red” to the robot do not speak to the question of whether they recognize the phenomenality of this state. Peressini pushes an especially interesting version of the objection, presenting new empirical evidence and suggesting that lay people do in fact have a concept of phenomenality. In this paper, I respond to Peressini’s objections, and the ambiguity objection more generally, arguing that the new data does not undermine Sytsma and Machery’s conclusion. (shrink)

This paper connects the hard problem of consciousness to the interpretation of quantum mechanics. It shows that constitutive Russellian pan(proto)psychism (CRP) is compatible with Everett’s relative-state (RS) interpretation. Despite targeting different problems, CRP and RS are related, for they both establish symmetry between micro- and macrosystems, and both call for a deflationary account of Subject. The paper starts from formal arguments that demonstrate the incompatibility of CRP with alternative interpretations of quantum mechanics, followed by showing that RS entails Russellian pan(proto)psychism. (...) Therefore, CRP and RS are mutually supportive. It then provides a unified ontological picture by combining CRP and RS. The challenge faced by CRP, the combination problem, can be resolved by adopting a RS version of quantum mechanics. Technically, this is achieved by a co-consciousness relation capable of explaining the difference between first-person and third-person perspectives. The hierarchical structure of the relation removes any concern on the structural mismatch between the physical and the phenomenal. (shrink)
