I lay out the framework for my theory of sensory imagination in “Imagining as a guide to possibility.” Sensory imagining involves mental imagery , and crucially, in describing the content of imagining, I distinguish between qualitative content and assigned content. Qualitative content derives from the mental image itself; for visual imaginings, it is what is “pictured.” For example, visually imagine the Philadelphia Eagles defeating the Pittsburgh Steelers to win their first Super Bowl. You picture the greenness of the field and (...) the football’s brown oblong shape. Some of what you imagine isn’t explicitly pictured, however. That it is Sunday, that it is the Super Bowl: these facts are assigned. (shrink)

Characterizing the first- and third-person perspectives is essential to the study of consciousness, yet we lack a rigorous definition of or criteria for these two perspectives. Our intuitive understanding of how personal pronouns help to specify the perspectives gives rise to mutually exclusive notions of the first-person perspective. This contradiction thwarts our progress in studying consciousness. We can resolve the current ambiguity of the first-person perspective by introducing a new distinction between the first-person and third-person perspectives, based on two modes (...) of consciousness: reflective and non-reflective. The purpose of this paper is to explain this new proposal, to elucidate the grounds for it, and to briefly suggest benefits from its use. (shrink)

This paper extends three decades of work arguing that researchers who discuss consciousness should not restrict themselves only to (adult) human minds, but should study (and attempt to model) many kinds of minds, natural and artificial, thereby contributing to our understanding of the space containing all of them. We need to study what they do or can do, how they can do it, and how the natural ones can be emulated in synthetic minds. That requires: (a) understanding sets of requirements (...) that are met by different sorts of minds, i.e. the niches that they occupy, (b) understanding the space of possible designs, and (c) understanding complex and varied relationships between requirements and designs. Attempts to model or explain any particular phenomenon, such as vision, emotion, learning, language use, or consciousness lead to muddle and confusion unless they are placed in that broader context. A methodology for making progress is summarised and a novel requirement proposed for a theory of how human minds work: the theory should support a single generic design for a learning, developing system that, in addition to meeting familiar requirements, should be capable of developing different and opposed philosophical viewpoints about consciousness, and the so-called hard problem. In other words, we need a common explanation for the mental machinations of mysterians, materialists, functionalists, identity theorists, and those who regard all such theories as attempting to answer incoherent questions. No designs proposed so far come close. (shrink)

Muchos psiquiatras se encuentran constantemente con pacientes cuyos síntomas incluyen trastornos o alteraciones de la conciencia. Infortunadamente, el significado del término conciencia es poco claro. Este artículo hace un repaso sistemático de varios significados atribuidos a dicho término, así como de diversos problemas filosóficos asociados. Asimismo, reconstruye varias teorías filosóficas y científicas de la conciencia, identificando sus ventajas y desventajas. Al final, ofrece algunas sugerencias para el uso del término conciencia en la psiquiatría.

Based on the technique of pressure blinding of the eye, two types of after-image were identified. A physicalist or mind/brain identity explanation was established for a negative a AI produced by moderately intense stimuli. These AI's were shown to be located in the neurons of the retina. An illusory AI of double a grating's spatial frequency was also produced in the same structure and was both prevented from being established and abolished after establishment by pressure blinding, thus showing that the (...) location was not more central. The illusory AI was predicted from the known non-linearity in the retina and this is the first case of a clear cut type-type identity of a sensation and a neural process. Some implications for the concepts of the explanatory gap between neurology and consciousness and multiple neural realizations of conscious states and topic neutrality are discussed. (shrink)

At the very heart of the mind-body problem is the question of the nature of consciousness. It is consciousness, and in particular _phenomenal_ consciousness, that makes the mind-body relation so deeply perplexing. Many philosophers hold that no defi nition of phenomenal consciousness is possible: any such putative defi nition would automatically use the concept of phenomenal consciousness and thus render the defi nition circular. The usual view is that the concept of phenomenal consciousness is one that must be explained by (...) means of specifi c examples and associated comments. (shrink)

That there is an epistemological difference between the mental and the physical is well- known. Introspection readily generates knowledge of one’s own conscious experience, but fails to yield evidence for the existence of anything physical. Conversely, empirical investigation delivers knowledge of physical properties, but neither finds nor requires us to posit conscious experience. In recent decades, a series of neo-Cartesian arguments have emerged that rest on this epistemological difference and purport to demonstrate that mind-brain identity is false and that consciousness (...) is not even realized by or supervenient on physical properties. Where Descartes argued he could clearly and distinctly conceive mind and body as existing separately, contemporary anti-physicalists hold that the conceivability of worlds in which actual world correlations between physical and phenomenological properties fail shows that these correlations are contingent rather than logically or metaphysically necessary. Together with Descartes, they conclude from conceivability that identity, as well as strong supervenience, is false. 1 If the argument of this paper is correct, however, then there is an argument for dualism that arises from the epistemological distinction, is grounded in the Meditations, and is yet distinct from the " 1 " conceivability arguments pursued both by Descartes and contemporary anti-physicalists. Furthermore, the argument is immune to the standard objections to conceivability arguments: its conclusion follows even if there are a posteriori identities between physical and phenomenal properties.

It's a common idea in philosophy that we possess a peculiar kind of "phenomenal concept" by which we can think about our conscious states in "inner" and "direct" ways, as for example, when I attend to the way a current pain feels and think about this feeling as such. Such phenomenal ways of thinking figure in a variety of theoretical contexts. The bulk of this article discusses their use in a certain strategy – the phenomenal concept strategy – for defending (...) the physicalist view that conscious states are reducible to brain states. It also considers, more briefly, how phenomenal concepts have been used to defend dualism about consciousness, and how they have been used to explain our special access to our consciousness. It concludes with a discussion about whether, and in what more precise sense of the term, we at all possess "phenomenal concepts" of our conscious states. (shrink)

This paper is an attempt to understand and assess Thomas Nagel's influential case against physicalism in the philosophy of mind. I show that Nagel has claimed that experience is "subjective", or "essentially connected with a single point of view" in at least three different senses: first, in the sense that it is essential to every experience that there be something it is like to have it; second, in the sense that what an experience is like for its possessor cannot be (...) understood by a radically different type of organism; and third, in the sense that an experience cannot be "apprehended" or "observed" from a third-person perspective. I also show that these three claims have entered into two different arguments for his view that experience cannot be accounted for in physicalist terms. By way of assessment, I suggest that physicalists have decent resources for responding to the second and third of Nagel's claims about the subjectivity of experience, but that they currently have less convincing things to say about the first claim.

According to a widely held physicalist view, consciousness is identical with some physical or functional phenomenon just as liquidity is identical with loose molecular connection. To many of us, this claim about consciousness seems more problematic than the claim about liquidity. To many—including many physicalists—the identification of consciousness with some physical phenomenon even seems “absurd” or “crazy”. A full defence of physicalism should explain why the allegedly correct hypothesis comes across this way. If physicalism is true and we have reason (...) to accept it, why does it seem “absurd”? One possibility is that this is fully explained by the fact that we have an erroneous understanding of consciousness or its physical basis. This explanation is embraced by few if any physicalists. It is rejected by many, including proponents of the “phenomenal concept strategy”, which lately has become the dominant strategy for defending physicalism. But the “error explanation” is clearly the most plausible explanation that is available to physicalists. So this paper argues. (shrink)

There are two important philosophical research programmes on explanation in the twentieth century—the search for an account or model of scientific explanation, and the defence of inference to the best explanation as a rational form of inference. These two research programmes have largely developed independently from one another. This paper argues that bringing the two research programmes in contact promises to yield fruitful discussion. I consider and reject two arguments for keeping the two research programmes separate. I outline several issues (...) related to both research programmes that would benefit from inter(sub)disciplinary dialogue. (shrink)

I argue that the physiological, phenomenal and conceptual constitute a trichotomous hierarchy of emergent categories. I claim that each category employs a distinctive type of interactive mechanism that facilitates a meaningful kind of environmental discourse. I advocate, therefore, that each have a causal relation with the environment but that their specific class of mechanism qualifies distinctively the meaningfulness of that interaction and subsequent responses. Consequently, I argue that the causal chain of physical interaction feeds distinctive value-laden constructions that are ontologically (...) distinct for each category. Within the limitations of the interactive mechanisms of each category, increasingly sophisticated forms tend to evolve. The increase in sophistication in each category inevitably leads to the emergence of the novel mechanism particular to the next in the hierarchy. In essence, there is an emergent hierarchy of evolving categories delineated by the nature of their mechanism of environmental engagement. I argue that biochemical mechanisms have a tendency to evolve meaningfully, specifically in a way that is both qualitatively relevant and responsive to environmental particulars. I explain that these mechanisms set in play an organisational imperative that leads to the emergence of the capacity to evaluate and prioritise qualitative biochemical assimilations which, inevitably, generates a subjectively individuated experience phenomenon. I then relate this to the novel characteristics of the human perspective. (shrink)

In this paper I argue that when we try to describe the specifically self-aware part of the mind, as opposed to the host of unconscious psychic activities, we face a potentially fatal difficulty - one I have termed ‘the inconceivability problem’. Because of the entanglement of the subject and the object in observations of subjectivity, and certain conceptual circularities, it seems we might never be able to represent the self-conscious mind with anything other than itself. This could leave consciousness studies (...) in a very awkward position. In an attempt to address this I propose that the concept of infinite regression, which is normally associated with the ‘homuncular fallacy’, be reinterpreted productively, in a way that puts self-reference at the heart of our conception of phenomenal experience. Looking at several examples of self-referential systems and theories of mind, including Zen, it seems one system in particular - video feedback - offers a rich source of analogies that might help us to visualize, if not explain, the operation of ‘world-embedded’ self-consciousness. I explain that this inquiry is an attempt to build a theoretical foundation for the construction of a ‘conscious art’, by which I mean a type of art that is, to some extent, aware of itself and its surroundings. (shrink)

A number of philosophers think that, while we cannot explain how the mind is physical, we can know that it is physical, nonetheless. That is, they accept both the explanatory gap between the mental and the physical and ontological physicalism. I argue that this position is unstable. Among other things, I argue that once one accepts the explanatory gap, the main argument for ontological physicalism, the argument from causation, looses its force. For if one takes physicaVnonphysical causation and ontological physicalism (...) to be equally mysterious, as physicalists who accept the explanatory gap are inclined to do, there is little justification for accepting ontological physicalism rather than rejecting the causal closure of the physical.

O Argumento dos Zumbis proposto por Chalmers, ao contrário de defender o dualismo, bane as qualia para um “mundo” onde elas não podem influenciar o julgamento que fazemos sobre nós mesmos. Por este motivo, pelo próprio argumento, podemos ser um zumbi e não saber. A isso Chalmers chamou de The Paradox of Phenomenal Judgment. O problema é que ele aceita tal paradoxo como parte de sua própria teoria. No entanto, este movimento filosófico não é aceitável e este paradoxo mina a (...) teoria de Chalmers por dentro mostrando que o argumento dos zumbis é, na verdade, um argumento contra o dualismo. Chalmers tenta resolver este problema com uma série de argumentos que tem como base o fato de que a consciência é um bruto explanandum indubitável. No entanto, tal tentativa fracassa por uma série de razões que mostram que mesmo se ele estivesse correto, ainda poderíamos ser um zumbi e não saber. (shrink)

In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental theory regarding its phenomenal aspect. There is an “explanatory gap” between our scientific knowledge of functional consciousness and its “subjective,” phenomenal aspects, referred to as the “hard problem” of consciousness. The phenomenal aspect of consciousness is the first-person answer to “what it’s like” question, and it (...) has thus far proved recalcitrant to direct scientific investigation. Naturalistic dualists argue that it is composed of a primitive, private, non-reductive element of reality that is independent from the functional and physical aspects of consciousness. Illusionists, on the other hand, argue that it is merely a cognitive illusion, and that all that exists are ultimately physical, non-phenomenal properties. We contend that both the dualist and illusionist positions are flawed because they tacitly assume consciousness to be an absolute property that doesn’t depend on the observer. We develop a conceptual and a mathematical argument for a relativistic theory of consciousness in which a system either has or doesn’t have phenomenal consciousness with respect to some observer. Phenomenal consciousness is neither private nor delusional, just relativistic. In the frame of reference of the cognitive system, it will be observable and in other frame of reference it will not. These two cognitive frames of reference are both correct, just as in the case of an observer that claims to be at rest while another will claim that the observer has constant velocity. Given that consciousness is a relativistic phenomenon, neither observer position can be privileged, as they both describe the same underlying reality. Based on relativistic phenomena in physics we developed a mathematical formalization for consciousness which bridges the explanatory gap and dissolves the hard problem. Given that the first-person cognitive frame of reference also offers legitimate observations on consciousness, we conclude by arguing that philosophers can usefully contribute to the science of consciousness by collaborating with neuroscientists to explore the neural basis of phenomenal structures.

Whenever an object constitutes, makes up or composes another object, the objects in question share a striking number of properties. This paper is addressed to the question of what might account for the intimate relation and striking similarity between constitutionally related objects. According to my account, the similarities between constitutionally related objects are captured at least in part by means of a principle akin to that of strong supervenience. My paper addresses two main issues. First, I propose independently plausible principles (...) by means of which to delineate, in a non-ad-hoc, non-stipulative and non-circular fashion, those properties which can be expected to be shared among constitutionally related objects in virtue of their being so related from those which in general cannot be expected to be shared, or which are shared for other reasons. Secondly,I spell out in detail the nature of the supervenience-principle at work in this context. My account thus aims at isolating, in a methodologically responsible fashion, the particular sort of restricted indiscernibility principle which is a component of the constitution-relation. (shrink)

Wilfrid Sellars [1962: 1] described philosophy as an attempt to ‘understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term’. But it is distinctive of philosophy that many of us are interested not only in how the world is but in ways that it could be. That is, philosophy is concerned with facts about modality. Some of the most important arguments in philosophy hinge on modal premises, and philosophers have (...) typically assumed special expertise in evaluating these modal premises. Replicating Goldvarg and Johnson-Laird’s [2000] study of modal illusions, we show that training in mathematics and not philosophy predicts success in overcoming such illusions (n = 395). This study is the first to test the modal expertise of professional philosophers directly. Our findings undermine claims to modal expertise. Philosophical training does not inoculate expert philosophers against basic mistakes in modal judgment. (shrink)

One criterion of an adequate analysis of the nature of consciousness has to do with its three parts, sides or elements. These are seeing and the like, thinking and the like, and desiring and the like. The seeming natures of the perceptual, reflective and affective parts or whatever of consciousness are different despite similarity. An adequate analysis of consciousness, even if general, will preserve the differences. It will pass the test of what you can call differential phenomenology.

Consciousness is what makes the mind-body problem really intractable. My reading of the situation is that our inability to come up with an intelligible conception of the relation between mind and body is a sign of the inadequacy of our present concepts, and that some development is needed. Mind itself is a spatiotemporal pattern that molds the metastable dynamic patterns of the brain.

In 1989 Oxford University Press launched a new programme of monographs in moral philosophy entitled the ‘Oxford Ethics Series’. Given that the series' editor is Derek Parfit it is unsurprising that the books published to date feature rigorous analysis and argumentation regarding the nature of reasons and requirements. Perhaps by way of intended commitment to this profile, the following brief statement appears on the cover of the first volume : ‘The books in the series will contain philosophical arguments about morality (...) or rationality. The aim will be to make undeniable progress’. (shrink)

There is disagreement among contemporary theorists regarding human well-being. On one hand there are “substantive good” views, according to which the most important elements of a person’s well-being result from her nature as a human, rational, and/or sentient being. On the other hand there are “agent-constituted” views, which contend that a person’s well-being is constituted by her particular aims, desires, and/or preferences. Each approach captures important features of human well-being, but neither can provide a complete account: agent-constituted theories have difficulty (...) accounting for the normativity of their claims, and substantive good theories have difficulty accounting for how a person’s actually adopted aims shape what is good for her and hence what she has reason to do. I articulate and defend a hybrid view that equals these approaches in systematicity and completeness of explanation yet seeks to surpass them in coherence with our ordinary judgments about what human well-being consists in. This hybrid view maintains, with agent-constituted theories, that a person’s well-being is (1) significantly constituted by her actually adopted aims; (2) deeply contingent; (3) agent-relative; (4) significantly dependent on spatially and temporally remote events; and (5) significantly independent of her experiences. The hybrid view also maintains, with substantive good theories, that a person’s well-being is (6) in part determined by facts independent of her aims, desires, and preferences; (7) such that all her aims are subject to critical evaluation and revision; and (8) constituted by her aims only if these aims are choiceworthy.

The ‘value-free ideal’ has been called into question for several reasons. It does not include “epistemic values”—viewed as characteristic of ‘good science’—and rejects the so-called ‘contextual’, ‘non-cognitive’ or ‘non-epistemic’ values—all of them personal, moral, or political values. This paper analyzes a possible complementary argument about the dubitable validity of the value-free ideal, specifically focusing on social sciences, with a two-fold strategy. First, it will consider that values are natural facts in a broad or ‘liberal naturalist’ sense and, thus, a legitimate (...) part of those sciences. Second, the paper will not reject the value-free ideal; rather, it will construe this ideal in a special way, not casting values aside in sciences, but bringing them to the table and rationally discussing them. Today’s predominant naturalistic view has tended to ‘naturalize’ values by looking for physicalist explanations for them—a move resisted by defenders of normativism in social sciences. At the same time, a contending ‘liberal naturalist’ stream has emerged, claiming that not all natural entities can be explained by the methods and concepts of physical sciences, and favors a non-materialist naturalism which includes mind, consciousness, meaning and value as fundamental parts of nature that cannot be reduced to matter. Hence, it may be posited that non-epistemic values could be ‘naturally’ included in the field of human sciences. (shrink)

: This article seeks to explain how thought experiments work, and also the reasons why they can fail. It is divided into four sections. The first argues that thought experiments in philosophy and science should be treated together. The second examines existing accounts of thought experiments and shows why they are inadequate. The third proposes a better account of thought experiments. According to this account, a thought experimenter manipulates her worldview in accord with the “what if” questions posed by a (...) thought experiment. When all necessary manipulations are carried through, the result is either a consistent model or a contradiction. If a consistent model is achieved, the thought experimenter can conclude that the scenario is possible; if a consistent model cannot be constructed, then the scenario is not possible. The fourth section of the article uses this account to shed light on the circumstances in which thought experiments fail. (shrink)

The paper offers a general critique of physicalism and of one variety of nonphysicalism, arguing that such theses are untenable. By distinguishing between the absolute conception of reality and the causal completeness of physics it shows that the 'explanatory gap' is not merely epistemic but metaphysical. It defends the essential subjectivity and unity of consciousness and its inseparability from a self-conscious autonomous rational and moral being. Casting a favourable light on dualism freed from misconceptions, it suggests that the only plausible (...) way forward in the search for an understanding of both physical and mental reality is a recognition of the mind as a metaphysically distinct entity.

Abhidharma Buddhist philosophy presents a version of what is now often called “panprotopsychism.” The most pressing group of problems for the Abhidharma panprotopsychism, like all other panpsychist views, is what Seager calls “the combination problem.” There are at least three versions of the problem: the subject-combination problem; the quality-combination problem; and the structure-combination problem. I begin with the Abhidharma Buddhist version of panprotopsychism and its account of conscious experience. The main focus of this paper is to show that Abhidharma panprotopsychist (...) account of conscious experience solves the quality-combination problem. In the last and closing Section, I look at other versions of the combination problem, primarily the subject-combination problem and the structural problem and provide a sketch of the Abhidharma Buddhist response to these.

In the standard thought experiments, dualism strikes many philosophers as true, including many non-dualists. This ‘striking’ generates prima facie justification: in the absence of defeaters, we ought to believe that things are as they seem to be, i.e. we ought to be dualists. In this paper, I examine several proposed undercutting defeaters for our dualist intuitions. I argue that each proposal fails, since each rests on a false assumption, or requires empirical evidence that it lacks, or overgenerates defeaters. By the (...) end, our prima facie justification for dualism remains undefeated. I close with one objection concerning the dialectical role of rebutting defeaters, and I argue that the prospects for a successful rebutting defeater for our dualist intuitions are dim. Since dualism emerges undefeated, we ought to believe it. (shrink)

It is sometimes claimed that ordinary objects, such as mountains and chairs, are not material in their own right, but only in virtue of the fact that they are constituted by matter. As Fine puts it, they are “only derivatively material” (2003, 211). In this paper I argue that invoking “constitution” to account for the materiality of things that are not material in their own right explains nothing and renders the admission that these objects are indeed material completely mysterious. Although (...) there may be metaphysical contexts in which mysterianism can be accepted with equanimity, I further argue, the question of the materiality of quotidian objects is not one of them.

RÉSUMÉ: Cette étude examine la relation entre la demande que les zombies sont logiquement/métaphysiquement possible et de la position que la conscience phénoménal est epiphenomenal. Il est souvent présumé que la première entraîne ce dernier, et que, par conséquent, toute implausibility dans la notion de conscience epiphenomenalism remet en question la possibilité réelle de zombies. Quatre façons dont les zombist pourrait répondre sont examinées, et je soutiens que les deux les plus fréquemment rencontrés sont insuffisantes, mais les autres—dont l’un est (...) rarement formulés et l’autre nouveaux—sont plus persuasif. Le résultat, cependant, est que le zombist pourraient en effet être confronté à un engagement indésirables à l’epiphenomenalism de conscience. (shrink)

Analyzing the outline of the endless literature on consciousness, the separation between science and philosophy rather than being overcome, seems to come back in different shapes. According to this point of view, the hard problem seems to be how to study consciousness while avoiding a slip back to the old dualism. This article outlines the advantages of the phenomenological method. This method, more than getting over the mind-body separation, anticipates it through an open gaze, able to bring back the human (...) presence as something structurally “ambiguous.” Reintroducing Husserl's scientific project in a complete way, Francisco Varela opened up a research area yet to be explored, which promises to be fertile for neuroscience, provided that we accept that radicalism essential to phenomenology.

Bealer’s argument against Kripke is presented. We then show how Kripke could counteract it. Our idea that the identity materialist may have the possibility of explaining why type psychophysical identities only appear to be contingent (but are necessary), because we confuse the exemplified properties (one property) with the concepts that subsume them (two distinct concepts), is supported by McGinn’s and Nagel’s materialistic intuitions. It remains to be seen whether a critique of Kripke like that of Bealer runs counter to the (...) exemplified properties and the concepts that subsume them. We argue that Bealer’s criticism of Kripke does not contradict it. McGinn’s and Nagel’s intuitions support our idea. What we want to show is that, even if, from the anti-materialist side of the debate about the mind–body identity thesis, Bealer and Kripke agree on the general anti-materialist strategy but not on the strategies of phenomenological explanation (which for Bealer, Kripke neglects) and descriptivist explanation (which for Bealer is wrong), the disagreement between Bealer and Kripke still leaves open the materialist explanation of one property and two concepts. If there is an explanation for the illusion of contingency, it is quite possible that these type psychophysical identities are indeed necessary. (shrink)

I'll show that the kind of analogy between life and information [argued for by authors such as Davies (2000), Walker and Davies (2013), Dyson (1979), Gleick (2011), Kurzweil (2012), Ward (2009)] – that seems to be central to the effect that artificial mind may represent an expected advance in the life evolution in the Universe – is like the design argument, and that if the design argument is unfounded and invalid, the argument to the effect that artificial mind may represent (...) an expected advance in the life evolution in the Universe is also unfounded and invalid. However, if we are prepared to admit (though we should not do so) this method of reasoning as valid, I'll show that the analogy between life and information to the effect that artificial mind may represent an expected advance in the evolution of life in the Universe seems to suggest some type of reductionism of life to information, but biology respectively chemistry, or physics are not reductionist, contrary to what seems to be suggested by the analogy between life and information.

This peer-reviewed paper investigates the dominant underlying approach to aesthetic experience and conscious experience more generally – that is, a neo-Kantian phenomenological approach. In essence, I argue that such approaches are based on a petitio principii in relation to what I call the 'principle of appearing qua appearing' – a principle that, I suggest, underlies the dominant approach to aesthetic perception. So, the ramifications of this argument are that we ought to question the dominance of the phenomenological approach to experience, (...) and reassess our concepts of the aesthetic mode of perception in this light. The paper makes a specific contribution to knowledge in this field in that it identifies a weakness in the dominant arguments relevant to our understanding of conscious experience, and clears the path for views of conscious experience that emerge in cognitive science. The paper has been delivered at a number of major conferences, and is used as a course text at the American University of Berlin. (shrink)

This paper shows why qualia constitute a problem for any theory of mental phenomena. We use the term ‘qualia’ in reference to non-intentional features of mental states which are eminently qualitative, i.e. perceptions, emotions, moods and body sensations. These non-intentional features are usually described as intrinsic, ineffable, infallible, atomic, private, direct and irreducible to the physical. The paper also explains the absent qualia argument which is addressed as a critique to functionalism.

The late 19th-century Ignorabimus controversy over the limits of scientific knowledge has often been characterized as proclaiming the end of intellectual progress, and by implication, as plunging Germany into a crisis of pessimism from which Liberalism never recovered. My research supports the opposite interpretation. The initiator of the Ignorabimus controversy, Emil du Bois-Reymond, was a physiologist who worked his whole life against the forces of obscurantism, whether they came from the Catholic and Conservative Right or the scientistic and millenarian Left. (...) Du Bois-Reymond’s doubt that scientists would ever elucidate consciousness must therefore be seen as an endorsement, and not a rejection, of his faith in reason. (shrink)

Живым существам объективный мир представляется как совокупность чувственно воспринимаемых качеств, воспоминаний, ощущений, мыслей, желаний, убеж- дений и т.д. Почему произошло так, что объективный мир способствовал появлению су- ществ, обладающих субъективным представлением об окружающей их действительности. Почему объективный мир породил существ с субъективным восприятием мира? Эта статья во многом посвящена разрыву между объективным и субъективным, а также проблеме качественного характера феноменального сознания. Я утверждаю, что физиологическое, феноменальное и концептуальное составляют трехуровневую иерархию эмергентных кате- горий. Эти категории каузально и онтологически различны (или (...) разделены). Для каждой характерен уникальный механизм интеракции. Этот механизм создает условия для форми- рования наделенного значением дискурсивного взаимодействия с окружающей средой. Повышение уровня сложности организации в рамках каждой категории неизбежно приво- дит к появлению нового уровня в иерархии. Иначе говоря, существует эмергентная иерар- хия развивающихся категорий, определяемая природой их механизмов взаимодействия с окружающим миром. Что касается первой категории, я утверждаю, что биохимические механизмы склонны в своем развитии идти особым, наделенным значением путем, при котором качественно учитываются характеристики окружающей среды и обеспечивается реакция на них. Говоря о второй категории, я показываю, что эти механизмы дают орга- низму возможность оценки и приоритизации квалитативных ассимиляций. Далее я объяс- няю, почему этот процесс характеризует индивидуальный субъективный феноменальный опыт. Наконец, я говорю об этом с точки зрения уникального взгляда на мир, присущего человеку.

The idea that science explains or ought to explain every phenomenon finds Cartesian dualism of mind and body to be an unsatisfactory thesis. Consequently we have a variety of materialist theories regarding mind and consciousness. In recent times, we come across many philosophers who are committed to the scientific world picture, trying to locate mind within a world that is essentially physical.The central problems these philosophers have to tackle consist of consciousness and mental causation. In what follows we discuss how (...) Husserlian phenomenology responds to this debate. (shrink)

Wittgenstein's arguments about rule-following and private language turn both on interpretation and what he called our 'pictures' of the mind. His remarks about these can be understood in terms of the conceptual metaphor of the mind as a container, and enable us to give a better account of physicalism.

It is now conventional wisdom that conscious experience — or in Nagel’s canonical characterization, “what it is like to be” for an organism — is what makes the mind-body problem so intractable. By the same token, our current conceptions of the mind-body relation are inadequate and some conceptual development is urgently needed. Our overall aim in this paper is to make some progress towards that conceptual development. We first examine a currently neglected, yet fundamental aspect of consciousness. This aspect is (...) the spontaneity of consciousness, by which we mean its inner plasticity and inner purposiveness. We then sketch a “neurophenomenological” framework for thinking about the relationship between the spontaneity of consciousness and dynamic patterns of brain activity as studied in cognitive neuroscience. We conclude by proposing that the conscious mentality of sentient organisms or animals is active and dynamic, and that this “enactive” conception of consciousness can help us to move beyond the classical dichotomy between materialism and dualism.

Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)
