Consciousness is arguably the most important area within contemporary philosophy of mind and perhaps the most puzzling aspect of the world. Despite an explosion of research from philosophers, psychologists, and scientists, attempts to explain consciousness in neurophysiological, or even cognitive, terms are often met with great resistance. In The Consciousness Paradox, Rocco Gennaro aims to solve an underlying paradox, namely, how it is possible to hold a number of seemingly inconsistent views, including higher-order thought (HOT) theory, conceptualism, infant (...) and animal consciousness, concept acquisition, and what he calls the HOT-brain thesis. He defends and further develops a metapsychological reductive representational theory of consciousness and applies it to several importantly related problems. Gennaro proposes a version of the HOT theory of consciousness that he calls the "wide intrinsicality view" and shows why it is superior to various alternatives, such as self-representationalism and first-order representationalism. HOT theory says that what makes a mental state conscious is that a suitable higher-order thought is directed at that mental state. -/- Thus Gennaro argues for an overall philosophical theory of consciousness while applying it to other significant issues not usually addressed in the philosophical literature on consciousness. Most cognitive science and empirical works on such topics as concepts and animal consciousness do not address central philosophical theories of consciousness. Gennaro’s integration of empirical and philosophical concerns will make his argument of interest to both philosophers and nonphilosophers. (shrink)

If not a paradox, consciousness is at least an enigma. Many believe consciousness is hard to have, whereas others are panpsychists. Many hold that consciousness is hard to understand, perhaps impossibly so, whereas others believe we already have available an adequate general understanding of consciousness. Rocco Gennaro belongs to the second camp, and in this important work he explains why.In The Paradox of Consciousness, Gennaro develops and defends a higher-order thought (HOT) theory of consciousness. A HOT theory is (...) an alternative to theories that consciousness depends on a “global workplace” that integrates and processes data from multiple sense modalities, or that what makes a conscious first-order mental state is what the state represents (“representationalism”). Any of these causal/computational theories has the great advantage over, say, quantum approaches, of providing a large-scale blueprint for actually designing a system that, if the theory is correct, would be conscious.

First, I want to start off by saying that The Consciousness Paradox is a wonderful book: well written, strongly argued, and impressively thorough. This is no great surprise, given the quality we've come to expect from Rocco Gennaro over the years, but it is a great thing to have a canonical statement of his view in one place and to have so many of the details of his theory of consciousness filled in. I also want to express my honour (...) at being a part of this symposium. (shrink)

Gennaro presents a version of the higher-order thought theory of consciousness that differs from the version defended by Rosenthal . I explore several key differences between Gennaro's and Rosenthal's views, with an eye toward establishing that Rosenthal's Extrinsic Higher-Order Thought theory is preferable to Gennaro's Wide Intrinsicality View . Gennaro's attempts to demonstrate the superiority of the WIV rest on an unargued and implausible assumption to the effect that the higher-order intentional contents of self-representing conscious states are necessarily accurate. Gennaro (...) relies on this assumption in avoiding what he sees as problematic consequences of Rosenthal's EHOT theory, which countenances the possibility that higher-order thoughts sometimes misrepresent lower-order states. I argue that these consequences, far from being problematic, actually constitute a strength of the EHOT theory, allowing it to explain phenomena such as dental fear, perceptual learning, and rare c..

My overall goal in The Consciousness Paradox: Consciousness, Concepts, and Higher-Order Thoughts is to solve what I take to be a paradox with regard to holding a series of interrelated theses, including a version of the higher-order thought theory of consciousness which says that what makes a mental state conscious is that there is a suitable higher-order thought directed at the mental state. Higher-order thoughts are metapsychological or meta-cognitive states, that is, mental states directed at other mental states. (...) This theory is primarily concerned with explaining how conscious mental states differ from unconscious mental states. In The Consciousness Paradox I defend and further develop a metapsychological reductive representational theory of consciousness and then apply it to several importantly related problems including concept acquisition and animal consciousness. (shrink)

There is much that is interesting in Gennaro's discussion of concepts and concept acquisition, and in general I am very sympathetic to the goals of his book, even if not with every detail (for another account of these issues that I don't fully agree with see Rosenthal 2005, chapter 7). I agree that we have good reason to think that some version of a higher-order thought theory of consciousness could be true and that this is consistent with animals and infants (...) having conscious experience. However, Gennaro and I disagree on the very basic issue of how we formulate the higher-order theory and its explanatory goals, and so I will focus on these more basic issues in the remainder of this review.

"The book presents in accessible fashion recent important work on the self and self-consciousness and also moves the issues forward with interesting new ideas. It provides a notably crisp and clear treatment of some extremely intriguing topics." -- Jane Heal, Department of Philosophy, University of Cambridge In this book, José Luis Bermú dez addesses two fundamental problems in the philosophy and psychology of self-consciousness: (1) Can we provide a noncircular account of fully fledged self-conscious thought and language in terms of (...) more fundamental capacities? (2) Can we explain how fully fledged self-conscious thought and language can arise in the normal course of human development? Bermú dez argues that a paradox (the paradox of self-consciousness) arises from the apparent strict interdependence between self-conscious thought and linguistic self-reference. The paradox renders circular all theories that define self-consciousness in terms of linguistic mastery of the first-person pronoun. It seems to follow from the paradox of self-consciousness that no such account or explanation can be given. Drawing on recent work in empirical psychology and philosophy, the author argues that any explanation of fully fledged self-consciousness that answers these two questions requires attention to primitive forms of self-consciousness that are prelinguistic and preconceptual. Such primitive forms of self-consciousness are to be found in somatic proprioception, the structure of exteroceptive perception, and prelinguistic forms of social interaction. The author uses these primitive forms of self-consciousness to dissolve the paradox ofself-consciousness and to show how the two questions can be given an affirmative answer. (shrink)

The so–called paradox of self–consciousness suggests that self–consciousness, understood as the capacity to think about oneself in a first–person way, cannot be explained. The author of the paradox contends that the only way to avert this result is by invoking the notion of nonconceptual first–person thought. This contention is rooted in adherence to the Linguistic Priority Principle, which dictates that pre–and nonlinguistic creatures lack concepts. I argue that the latter claim is dubious, and that the paradox of (...) self–consciousness can be better disarmed by denying the dependence of first–person conceptual thought on first–person language.

Seemingly contrary ideas of Nirvana are found in early Buddhist literature. Whereas some texts describe one who attains Nirvana as being conscious of everything, others depict Nirvana as a state in which consciousness has no object but emptiness or Nirvana. In this paper I deal with this paradox of Nirvana consciousness by exploring the correlations between several statements in early Buddhist texts. A number of sutta passages are cited to show that they contain doctrinal elements which, when considered collectively, (...) may cast valuable light on how to reconcile this paradox. Two pivotal notions are ‘non-abiding consciousness’ and ‘consciousness that is infinite, pervasive all around’. These two notions are connected to each other and seem to subsume or bridge the two strikingly distinct forms of Nirvana consciousness mentioned above. Nirvana consciousness said to be ‘non-abiding’, which is analogous to ‘without object’, does ‘not abide’ in any objects in the sense that it does not cling to them or rest on them. The ‘infinite, all-pervasive’ consciousness, based on stopping normal consciousness, does not depend on any sense objects, and hence it is unconditioned by them and operates unhindered. Nirvana consciousness thus constitutes the infinite realization free from all conditioning and hindrance. This resonates with the idea that one who attains Nirvana is conscious of everything.

I offer a novel account of the absurdity of Moore-paradoxical assertion in terms of an interlocutor’s fully conscious beliefs. This account starts with an original argument for the principle that fully conscious belief collects over conjunction. The argument is premised on the synchronic unity of consciousness and the transparency of belief.

Chalmers and Hájek argue that on an epistemic reading of Ramsey’s test for the rational acceptability of conditionals, it is faulty. They claim that applying the test to each of a certain pair of conditionals requires one to think that one is omniscient or infallible, unless one forms irrational Moore-paradoxical beliefs. I show that this claim is false. The epistemic Ramsey test is indeed faulty. Applying it requires that one think of anyone as all-believing and if one is rational, to (...) think of anyone as infallible-if-rational. But this is not because of Moore-paradoxical beliefs. Rather it is because applying the test requires a certain supposition about conscious belief. It is important to understand the nature of this supposition. (shrink)

Any physical explanation of consciousness seems to leave unresolved the ‘explanatory gap': Isn't it conceivable that all the elements in that explanation could occur, with the same information processing outcomes as in a conscious process, but in the absence of consciousness? E.g. any digital computational process could occur in the absence of consciousness. To resolve this dilemma, we propose a biological-process-oriented physiological- phenomenological characterization of consciousness that addresses three ‘paradoxical’ qualities seemingly incompatible with the empirical realm: The dual location of (...) phenomenal properties ‘out there’ yet ‘in here’ in consciousness; the mysterious ‘thickness’ of the specious present; the feeling of ‘free agency', that we can voluntarily direct our actions, including the act of conscious attention, while at the same time attention and the emotions that direct it seem responsive to physiological substrates with physical causes. These paradoxes are then resolved by relating three elements of consciousness: organismically interested anticipation; sensory and proprioceptive imagery generated by the interested anticipation rather than by sensory input; resonating of these activities with activity stimulated by sensory data, where the interested anticipation precedes the processing of the input. Each of these elements is bridged to physiological processes such that, if they occur in a certain relation to each other, we can understand why they would inevitably be accompanied by the corresponding elements of conscious experience.

Dehaene and Naccache, Dennett and Jack and Shallice “see convergence coming from many different quarters on a version of the neuronal global workspace model†(Dennett, p. 1). (Boldface references are to papers in this volume.) On the contrary, even within this volume, there are commitments to very different perspectives on consciousness. And these differing perspectives are based on tacit differences in philosophical starting places that should be made explicit.  Indeed, it is not clear that different uses of “consciousness†and (...) “awareness†in this volume can be taken to refer to the same phenomenon. More specifically, I think there are three different concepts of consciousness in play in this issue. The global workspace model makes much more sense on one of these than on the others.

Sidney Shoemaker has given an influential explanation of the absurdity of Moore-paradoxical belief in terms of conscious belief. Here I offer a novel account of the absurdity of Moore-paradoxical assertion in terms of an interlocutor’s fully conscious beliefs. This account starts with an original argument for the principle that fully conscious belief collects over conjunction. The argument is premised on the synchronic unity of consciousness and the transparency of belief.

Beginning with the paradoxes of zombie twins, we present an argument that dualism is both true and false. We show that avoiding this contradiction is impossible. Our diagnosis is that consciousness itself engenders this contradiction by producing contradictory points of view. This result has a large effect on the realism/anti-realism debate, namely, it suggests that this debate is intractable, and furthermore, it explains why this debate is intractable. We close with some comments on what our results mean for metaphysics and (...) philosophy, in general. (shrink)

This paper uses a paradox inherent in any solution to the Hard Problem of Consciousness to argue for God’s existence. The paper assumes we are “thought machines”, reading the state of a relevant physical medium and then outputting corresponding thoughts. However, the existence of such a thought machine is impossible, since it needs an infinite number of point-representing sensors to map the physical world to conscious thought. This paper shows that these sensors cannot exist, and thus thought cannot come (...) solely from our physical world. The only possible explanation is something outside, argued to be God. (shrink)

Viewed from a first-person perspective consciousness appears to be necessary for complex, novel human activity - but viewed from a third-person perspective consciousness appears to play no role in the activity of brains, producing a "causal paradox". To resolve this paradox one needs to distinguish consciousness of processing from consciousness accompanying processing or causing processing. Accounts of consciousness/brain causal interactions switch between first- and third-person perspectives. However, epistemically, the differences between first- and third-person access are fundamental. First- and (...) third-person accounts are complementary and mutually irreducible. (shrink)

Most theories and models of memory are based on two assumptions that contain theoretical problems. These problems are reflected in the memory-trace paradox, which consists in believing that the past is contained in the memory trace, and in the fallacy of the homunculus, which consists in assuming the existence of an unconscious intentional subject. We will discuss these and present an alternative hypothesis concerning the relationship between memory, consciousness and temporality. This holds that consciousness is not a unitary dimension, (...) but is the set of distinct and original modes to address the object. Among the modes of consciousness, a distinction is made between Knowing Consciousness (KC) and Temporal Consciousness (TC). KC describes the mode of addressing the object in order to know it. TC describes the mode of consciousness that temporalizes its object according the subordinate structures of temporality, the past, the present and the future. Finally it is shown how the hypothesis accounts for a variety of memory disorders and phenomena while avoiding the memory- trace paradox and the fallacy of the homunculus. (shrink)

What José Luis Bermúdez calls the paradox of self-consciousness is essentially the conflict between two claims: (1) The capacity to use first-personal referential devices like “I” must be explained in terms of the capacity to think first-person thoughts. (2) The only way to explain the capacity for having a certain kind of thought is by explaining the capacity for the canonical linguistic expression of thoughts of that kind. (Bermúdez calls this the “Thought-Language Principle”.) The conflict between (1) and (2) (...) is obvious enough. However, if a paradox is an unacceptable conclusion drawn from apparently valid reasoning from apparently true premises, then Bermúdez’s conflict is no paradox. It is rather a conflict between the view that thought must be explained in terms of language, and the view that first person linguistic reference must be explained in terms of first-person thought. Neither view is immediately obvious, and nor is it obvious that the arguments for either are equally compelling. What we have here is a difference of philosophical opinion, not a paradox. (shrink)

A close-knit family of conceptual structures underlies the range of philosophical phenomena from Descartes' Cogito through semantic and set-theoretical paradoxes to some of the major limitative results of twentieth-century logic. At issue are questions of indexicals, the nature of semantics, free will and determinism, and contemporary debates regarding the nature of consciousness. The conceptual structures that underlie all of these are variations on a single theme: the theme of reflexivity. OUr attempt here is to characterize reflexive conceptual structures more thoroughly (...) and more precisely than has been done before, making explicit the structure of paradox and the clear connections to major logical results.

Is the location of consciousness in the objectively represented world intelligible? The paper examines the grounds for Nagel's negative answer, which can be presented as a response to the following paradox. (1) We are realists about consciousness. (2) Realism about a domain of reference requires commitment to the possibility of an objective, perspective-free conception of it. (3) The phenomenal character of an experience can only be captured by means of perspectival concepts. According to Nagel, we can have either realism (...) about consciousness or the link between realism and objectivity. He opts for the former, where this leads to the postulation of an essentially perspectivally reality inhabited by consciousness. I argue, contra Nagel, that questions about the intelligibility of locating consciousness in the objectively representable world should be asked relative the kinds of objectivity provided for by our spatial thought. Not only does this formally dissolve the paradox, as such thought allows for essential reliance on perspectival concepts; but it also shows how we do in fact make sense of the objective location of consciousness, in virtue of the link between spatial thought and something Strawson calls our ‘commonsense realism’ about physical objects, which ascribes ‘phenomenally-laden’ properties to such objects.

Human consciousness is widely understood to be underpinned by rich and diverse functional networks, whose breakdown results in unconsciousness. Candidate neural correlates of anesthetic-induced unconsciousness include: (1) disrupted frontoparietal functional connectivity; (2) disrupted brain network hubs; and (3) reduced spatiotemporal complexity. However, emerging counterexamples have revealed that these markers may appear outside of the state they are associated with, challenging both their inclusion as markers of conscious level, and the theories of consciousness that rely on their evidence. In this study, (...) we present a case series of three individuals in disorders of consciousness (DOC) who exhibit paradoxical brain responses to exposure to anesthesia. High-density electroencephalographic data were recorded from three patients with unresponsive wakefulness syndrome (UWS) while they underwent a protocol of propofol anesthesia with a targeted effect site concentration of 2 μg/ml. Network hubs and directionality of functional connectivity in the alpha frequency band (8–13 Hz), were estimated using the weighted phase lag index (wPLI) and directed phase lag index (dPLI). The spatiotemporal signal complexity was estimated using three types of Lempel-Ziv complexity (LZC). Our results illustrate that exposure to propofol anesthesia can paradoxically result in: (1) increased frontoparietal feedback-dominant connectivity; (2) posterior network hubs; and (3) increased spatiotemporal complexity. The case examples presented in this paper challenge the role of functional connectivity and spatiotemporal complexity in theories of consciousness and for the clinical evaluation of levels of human consciousness.

The theory of consciousness proposed by O'Brien & Opie is open to the Sorites paradox, for it defines a consciousness system internally in terms of computationally relevant units which add up to consciousness only if sufficient in number. The Sorites effect applies on the assumed level of features.

In this journal, Hamid Vahid argues against three families of explanation of Moore-paradoxicality. The first is the Wittgensteinian approach; I assert that p just in case I assert that I believe that p. So making a Moore-paradoxical assertion involves contradictory assertions. The second is the epistemic approach, one committed to: if I am justified in believing that p then I am justified in believing that I believe that p. So it is impossible to have a justified omissive Moore-paradoxical belief. The (...) third is the conscious belief approach, being committed to: if I consciously believe that p then I believe that I believe that p. So if I have a conscious omissive Moore-paradoxical belief, then I have contradictory second-order beliefs. In their place, Vahid argues for the defective-interpretation approach, broadly that charity requires us to discount the utterer of a Moore-paradoxical sentence as a speaker. I agree that the Wittgensteinian approach is unsatisfactory. But so is the defective-interpretation approach. However, there is a satisfactory version of each of the epistemic and conscious-belief approaches. (shrink)

In Purple Haze: the Puzzle of Consciousness, Joseph Levine tells us that the mind-body problem.

Introspection is paradoxical in that it is simultaneously so compelling yet so elusive. This paradox emerges because although experience itself is indisputable, our ability to explicitly characterize experience is often inadequate. Ultimately, the accuracy of introspective reports depends on individuals' imperfect ability to take stock of their experience. Although there is no ideal yardstick for assessing introspection, examination of the degree to which self-reports systematically covary with the environmental, behavioural, and physiological concomitants of experience can help to establish the (...) correspondence between meta-consciousness and experience. We illustrate the viability of such an approach in three domains, imagery, mind-wandering, and hedonic appraisal, identifying both the situations in which introspections appear to be accurate and those in which they seem to diverge from underlying experience. We conclude with a discussion of the various factors that may cause meta-consciousness to misrepresent experience. (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.

Lucid dreams are dreams in which a person becomes aware that they are dreaming. They are different from ordinary dreams, not just because of the dreamer's awareness that they are dreaming, but because lucid dreams are often strikingly realistic and may be emotionally charged to the point of elation. Celia Green and Charles McCreery have written a unique introduction to lucid dreams that will appeal to the specialist and general reader alike. The authors explore the experience of lucid dreaming, relate (...) it to other experiences such as out-of-the-body experiences and apparitions, and look at how lucid dreams can be induced and controlled. They explore their use for therapeutic purposes such as counteracting nightmares. Their study is illustrated throughout with many case histories. (shrink)

Evolutionary fitness threats and rewards are associated with subjectively unpleasant and pleasant sensations, respectively. Initially, these correlations appear explainable via adaptation by natural selection. But here I analyse the major metaphysical perspectives on consciousness – physicalism, dualism, and panpsychism – and conclude that none help to understand the adaptive-seeming correlations via adaptation. I also argue that a recently proposed explanation, the phenomenal powers view, has major problems that mean it cannot explain the adaptive-seeming correlations via adaptation either. So the mystery (...) – call it the evolutionary paradox of consciousness – remains. Some have used this mystery to argue for non-naturalistic (e.g. theistic) explanations. But I propose a naturalistic, non-adaptive explanation of the adaptive-seeming correlations: namely, ‘sensational associative learning’ during development. In this perspective, pairing of particular sensations with unconditioned stimuli – fitness rewards or threats – cause the sensations themselves to come to be interpreted as good or bad, respectively. Sensations, like colours, that are not reliably paired with either fitness rewards or threats remain largely unvalenced. Sensational associative learning also provides explanations for adaptive-seeming structural aspects of sensations, such as the observation that sounds of different pitch are experienced as ordinal in correspondence to their wavelengths while the same is not true of colours of different hue. The sensational associative learning perspective appears compatible with physicalism, panpsychism, and dualism (though not epiphenomenalism). (shrink)

Description: The main tenor of The Paradox of Being Human is philosophical aimed at empowering man to look upon the transcendental as the primordial essence of the human. An attempt is made here to develop the Samkhya and the Vedanta schools where the essence of Indian Philosophy is verbalized. Man is paradoxical-he is here in the world and yet not consumed by the fact of worldliness. The paradox is not arbitrary-it is woven within the very structure of human (...) consciousness. The paradox is that man is worldly and otherworldly at the same time-it is objective and the subjective fused into one whole. The objective and the subjective or, as Sartre puts it, the en-soi and pour-soi, are two facets of the same humanness. They are to be justified visa-vis the ultimate Being in which man is anchored. The intensification of the subjective is thus an opening into the ontology of Being which is perennial to our metaphysical source. (shrink)
