We have two main aims: to construct mathematical models for analysing determinism, causality and supervenience; and then to use these to demonstrate the possibility of constructing an ontic construal of the operation of free will - one requiring both the presentation of genuine alternatives to an agent and their selecting between them in a manner that permits the attribution of responsibility. Determinism is modelled using trans-temporal ontic links between discrete juxtaposed universe states and shown to be distinct from predictability. Causality (...) is defined on a temporal sequence of δ-algebras and quantified using a measure. The measure leads to definitions of causal overdetermination and epiphenomena. Proofs are constructed to demonstrate deterministic universes must carry their properties essentially but not necessarily locally. We argue determinism and causality are separate doctrines. These models and results are marshalled to put the case that a counterfactual construal of ontic choice cannot work. In response we propose ‘immanence’ - a modified form of indeterminism whereby a universe can present choices to its denizens. We prove that beings subsumed within a universe cannot pilot their own actions. We then argue these beings can exercise free will only when selecting between choices inhering within immanent relata. A being is responsible for its selections if and only if it is constituted of a temporally evolving deterministic substructure. Our proposal is novel: it avoids injecting indeterminism into the decision process. Topological models for property supervenience are developed and used to reconstruct standard definitions from the literature. These are then used to demonstrate considerations of supervenience do not affect our arguments. We have demonstrated that a model of the exercise of free will involving both genuine choices and responsibility is possible but can only operate within a non-deterministic universe possessing specific traits.

In the thesis I offer an analysis of the metaphysical underpinnings of the extended cognition thesis via an examination of standard views of metaphysical building (or, dependence) relations. -/- In summary form, the extended cognition thesis is a view put forth in naturalistic philosophy of mind stating that the physical basis of cognitive processes and cognitive processing may, in the right circumstances, be distributed across neural, bodily, and environmental vehicles. As such, the extended cognition thesis breaks substantially with the still (...) widely held view in cognitive science and philosophy of mind, namely that cognitive processes and cognitive processing take place within the skin-and-skull of individual organisms. The standard view of metaphysical building relations can be expressed as the conjunction of two theses. First, that a metaphysical building relation – such as composition, constitution, realization, supervenience or emergence – is a relation of ontological dependence, because if a metaphysical building relation holds between X (or the Xs) and Y, then it is in virtue of X (or the Xs) that Y exists. Second, metaphysical building relations are synchronic (durationless) relations of ontological dependence. In the thesis, I propose an alternative diachronic framework by which to extend the standard synchronic accounts of metaphysical dependence relations, and by which to reformulate the metaphysical foundation of the extended cognition thesis. The project fills an important gap between analytical metaphysics (in particular, the metaphysics of dependence relations) and naturalistic philosophy of mind (especially the extended cognition thesis). To my knowledge there has been no attempt to establish a robust diachronic account of metaphysical building (or, dependence) relations such as, e.g., composition and constitution. However, this is precisely what I argue is required to properly advance and ground the metaphysics of extended cognition. Ultimately, my aim of reformulating the metaphysics of extended cognition consists in taking several steps toward a third-wave of extended cognition. (shrink)

En este artículo exploro el compatibilismo, el punto de vista según el cual la tesis del hiato o hueco explicativo entre lo fenoménico y lo físico es compatible con una metafísica fisicista. Defiendo que el argumento del dualismo de propiedades es un argumento incompatibilista más fuerte que el argumento de Jackson-Chalmers o el de Kripke y exploro críticamente algunos intentos recientes de replicar al mismo. La conclusión a la que llego es que una posición compatibilista capaz de dar una respuesta (...) adecuada al argumento del dualismo de propiedades sigue todavía pendiente de articulación. In this paper I explore compatibilism, the view that the claim that there is an explanatory gap between the phenomenal and the physical is compatible with an overall physicalist metaphysics. I argue that the property dualism argument is an incompatibilist argument which is stronger than the Jackson-Chalmers argument or Kripke's argument and I critically explore some recent attempts in the literature to deal with it. The conclusion is that a compatibilist view, one able to cope with the property dualism argument, is still pending. (shrink)

The debate between relationalism and representationalism in the philosophy of perception seems to have come to a standstill where opponents radically disagree on methodological principles or fundamental assumptions. According to Fish (this volume) this is because, not unlike Kuhnian scientific paradigms, the debate displays some elements of incommensurability. This diagnosis makes advancing the debate impossible. I argue that what is hindering progress is not a clash of research programmes, but a series of misunderstandings that can be avoided by disentangling the (...) different questions each theory is invested in and by making explicit the hidden assumptions at play in the debate. One such central assumption is what I call the Superficiality Constraint. This is the idea that the phenomenal character of experience is superficial with respect to introspection. I argue that we can make progress in the debate by assessing to what extent and at what cost relationalism can accommodate this constraint. (shrink)

Quality-space theory (QST) explains the nature of the mental qualities distinctive of perceptual states by appeal to their role in perceiving. QST is typically described in terms of the mental qualities that pertain to color. Here we apply QST to the olfactory modalities. Olfaction is in various respects more complex than vision, and so provides a useful test case for QST. To determine whether QST can deal with the challenges olfaction presents, we show how a quality space (QS) could be (...) constructed relying on olfactory perceptible properties and the olfactory mental qualities then defined by appeal to that QS of olfactory perceptible properties. We also consider how to delimit the olfactory QS from other modalities. We further apply QST to the role that experience plays in refining our olfactory discriminative abilities and the occurrence of olfactory mental qualities in non-conscious olfactory states. QST is shown to be fully applicable to and useful for understanding the complex domain of olfaction. (shrink)

A satisfactory solution to the problem of consciousness would take the form of a simple yet fully general model that specifies the precise conditions under which any given state of consciousness occurs. Science has uncovered numerous correlations between consciousness and neural activity, but it has not yet come anywhere close to this. We are still looking for the Newtonian laws of consciousness. -/- One of the main difficulties with consciousness is that we lack a language in which to formulate illuminating (...) generalizations about it. Philosophers and scientists talk about "what it’s like", sensations, feelings, and perceptual states such as seeing and hearing. This language does not allow a precise articulation of the internal structures of conscious states and their inter-relations. It is inadequate to capture relations of the kind we are looking for between conscious states and physical states. -/- In this thesis I refine and defend a theory of consciousness which promises to solve this regimentation problem: the representational theory of consciousness. I argue that the representational theory can solve the regimentation problem and smooth out other important obstacles to a fruitful study of consciousness. I also make a case for the theory independently of its payoffs, and I discuss the leading opposing theories at some length. (shrink)

The horizon of clinical memory modification, long the domain of science fiction, is rapidly approaching; it is therefore imperative that we understand the ethical implications of such neuromodificatory technologies. We might begin such inquiry with the public’s worries about these technologies, namely that modifying memory will concomitantly modify the self. Yet, before discerning the reasonableness of this worry, we must understand the meaning of “the self” in relation to memory. Distilling this conception of the self is the principal aim of (...) this thesis. I argue that many popular self-conceptions cannot capture our worries about neuromodification. Hence, I distill a novel such conception, which I call the Proustian Self—marshaling, to that end, not only neuroscientific evidence and metaphysical arguments but also literary-phenomenological analysis. I ultimately argue that this conception should be the target of further neuroethical inquiry regarding the prospect memory modification and its effects on putative patients. (shrink)

The sensorimotor theory is an influential account of perception and phenomenal qualities that builds, in an empirically supported way, on the basic claim that conscious experience is best construed as an attribute of the whole embodied agent's skill-driven interactions with the environment. This paper, in addition to situating the theory as a response to certain well-known problems of consciousness, develops a sensorimotor account of why we are perceptually conscious rather than not.

I look at some central positions in the mental causation debate – reductionism, emergentism, and nonreductive physicalism – on the hypothesis that mental causation is intelligible. On this hypothesis, mental causes and their effects are internally related so that they intelligibly “fit”, analogous to the way puzzle pieces interlock, or shades of red fall into order within a color sphere. The assumption of intelligibility has what I take to be a welcome consequence: deciding among rivals in the mental causation debate (...) could end up to be largely an empirical matter. (shrink)

Disjunctivism about perceptual appearances, as I conceive of it, is a theory which seeks to preserve a naïve realist conception of veridical perception in the light of the challenge from the argument from hallucination. The naïve realist claims that some sensory experiences are relations to mind-independent objects. That is to say, taking experiences to be episodes or events, the naïve realist supposes that some such episodes have as constituents mind-independent objects. In turn, the disjunctivist claims that in a case of (...) veridical perception like this very kind of experience that you now have, the experiential episode you enjoy is of a kind which could not be occurring were you having an hallucination. The common strategy of arguments from hallucination set out to show that certain things are true of hallucinations, and hence must be true of perceptions. For example, it is argued that hallucinations must have non-physical objects of awareness, or that such states are not relations to anything at all, but are at best seeming relations to objects. In insisting that veridical perceptual experience is of a distinct kind from hallucination, the disjunctivist denies that any of these conceptions of hallucination challenges our conception of veridical perceptions as relations to mind-independent objects. More specifically, I assume that the disjunctivist advocates naïve realism because they think that this position best articulates how sensory experience seems to us to be just through reflection. If the disjunctivist is correct in this contention, then anyone who accepts the conclusion of the argument from hallucination must also accept that the nature of sensory experience is other than it seems to us to be. In turn, one may complain that any such error theory is liable to lead to sceptical consequences. A Humean scepticism about the senses launches a challenge about our knowledge of the world through questioning the conception we have of what sense experience is, and how it can provide knowledge of the world.

According to perdurantism, objects persist by being spread out over time, just as composite three-dimensional objects are spread out over space. Just as a composite three-dimensional object is spread out over space by having spatial parts, objects persist, according to perdurantism, by having temporal parts. Perdurantism can be stated more precisely by saying what exactly a temporal part is. In the sequel, Theodore Sider's definition of "instantaneous temporal part" shall be assumed: x is an instantaneous temporal part of y at (...) instant t =df. x exists at, but only at, t; x is part of y at t; and x overlaps at t everything that is part of y at t. Much more could be and has been said about how perdurantism should be formulated. Though interesting in their own right, nothing of importance here turns on these matters of formulation. (shrink)

Fifty years ago the philosopher Wilfred Sellars identified two images of “man”, which he called respectively the “manifest image” and the “scientific image”; and he considered whether and how these two images could be reconciled. In this paper, I will very briefly look at the distinction drawn by Sellars and at his suggestions for reconciliation of these images. I will suggest that a broad distinction as suggested by Sellars can indeed usefully be drawn, but that the distinction can be more (...) helpfully characterised than it was by Sellars. I will argue that there are more ways of reconciling the two images than those proposed by Sellars. And I will elaborate on what I think are the most promising lines along which the reconciliation could take place. (shrink)

This thesis has, as its primary target, the neo-cartesianism, or property dualism of certain philosophers of mind: David Chalmers, Tim Bayne, and others. All begin with a pre-theoretic commitment to the view that all perceptual states are conscious. They define consciousness by saying that it is synonymous with having ‘qualia’ – a term directed at phenomenal properties which defy reduction to physical states. The thesis argues that this position is challenged by certain neurological conditions, - blindsight, visual form agnosia etc- (...) which we can generalise as ‘dissociations’: conditions in which functions are separated from awareness. The thesis holds that these are examples of unconscious perception, which present the case for a different pre-theoretic position, and a redefinition of concepts used in the vicinity. Insofar as the neo-cartesians recognise the empirical, their inclination to reject the dissociations is challenged with new cases and paradigms which have emerged in recent years. It is contended that the dissociations disrupt Chalmers’ coherence between the phenomenal and the psychological, Bayne’s commitment to the Unity of Consciousness, and Phillips’ campaign against unconscious perception. In addition, synaesthesia is advanced as a problem case for Bayne’s unity contention. I argue that the dissociations are not easily dismissed, and present a real challenge for neo-cartesianism. In exploring this challenge, the thesis contributes to the case for a different philosophy of mind – a Higher Order Thought approach. The notion of unconscious perception – it is contended - much more easily finds an accommodation in HOT theories, so this thesis contributes to existing arguments for that position. HOT theories also have an advantage in being receptive to reduction, in giving a developmental account of consciousness, and in being more open to the accommodation of empirical discoveries. In each respect, there is an advantage over the respective positions taken by Chalmers and Bayne. (shrink)

In this thesis, I elaborate and defend Donald Davidson's account of knowing one's own mental states that exhibit first-person authority. To that end, I place Davidson's account among others in the philosophical landscape concerning self-knowledge. Next, I examine his response to philosophical challenges that arise from mental content externalism and self-deception. Finally, I draw some insights froms Davidson's account to the broader aims of epsitemology.

The search for neural correlates of consciousness (or NCCs) is arguably the cornerstone in the recent resurgence of the science of consciousness. The search poses many difficult empirical problems, but it seems to be tractable in principle, and some ingenious studies in recent years have led to considerable progress. A number of proposals have been put forward concerning the nature and location of neural correlates of consciousness. A few of these include.

In recent years there has been an explosion of scientific work on consciousness in cognitive neuroscience, psychology, and other fields. It has become possible to think that we are moving toward a genuine scientific understanding of conscious experience. But what is the science of consciousness all about, and what form should such a science take? This chapter gives an overview of the agenda.

Scott Soames’ Reference and Description contains arguments against a number of different versions of two-dimensional semantics. After early chapters on descriptivism and on Kripke’s anti-descriptivist arguments, a chapter each is devoted to the roots of twodimensionalism in “slips, errors, or misleading suggestions” by Kripke and Kaplan, and to the two-dimensional approaches developed by Stalnaker (1978) and by Davies and Humberstone (1981). The bulk of the book (about 200 pages) is devoted to “ambitious twodimensionalism”, attributed to Frank Jackson, David Lewis, and (...) me. After a quick overview of two-dimensional approaches, I will focus on Soames’ discussion of ambitious twodimensionalism. I will then turn to a system advocated by Soames that is itself strikingly reminiscent of a two-dimensional approach. Two-dimensional semantic theories are varieties of possible-worlds semantics on which linguistic items can be evaluated relative to possibilities in two different ways, yielding two sorts of intensional semantic values, which can be seen as two “dimensions” of meaning. The second dimension is the familiar sort of Kripkean evaluation in metaphysically possible worlds, so that necessarily coextensive terms (such as ‘Hesperus’ and ‘Phosphorus’ or ‘water’ and ‘H2O’) always have the same semantic value. The first dimension behaves differently, so that there are typically at least some cases where necessarily coextensive terms have different semantic values on the first dimension. For this reason, the two-dimensional framework is sometimes seen as a way of granting many of the insights of a Kripkean approach to meaning (on the second dimension), while retaining elements of a Fregean approach to meaning (on the first dimension).

Zombies are hypothetical creatures of the sort that philosophers have been known to cherish. A zombie is physically identical to a normal human being, but completely lacks conscious experience. Zombies look and behave like the conscious beings that we know and love, but "all is dark inside." There is nothing it is like to be a zombie.

The present work explores various ways in which contingent evidence can impact metaphysics, while advocating that, just as a scientific realist allows for ampliative inferences to the unobservable, ampliative inferences from possible evidence can warrant possibility claims that lie beyond the reach of sensorial imagination. In slogan form: possible evidence is a guide to possibility. Drawing on Shoemaker’s (1969) argument for the possibility of time without change, I advocate the following principle: If there is a possible world at which the (...) observable facts make it objectively reasonable to conclude that p, then we should conclude that p is possibly true. This provides a route to contingentism in metaphysics, for, if one considers that there are worlds in which the observable facts make it objectively reasonable to conclude that p, and worlds in which the observable facts make it objectively reasonable to conclude that not-p, then my principle tells us that we should conclude that possibly-p and possibly not-p, i.e. that p is contingent. This contingency in what is reasonable to conclude, I suggest, occurs most saliently in debates where evidence of phenomenal experience and empirical science are marshalled to support one theory over another. I also explore some consequences of taking possible evidence to be a guide to possibility in this way, among them being an interesting modal analogue of the lottery paradox. (shrink)

According to Tim Crane, “the ’hard problem’ of consciousness is supposed to be the real heart of the mind-body problem in today’s philosophy”. The idea of the problem can be expressed in the following way: Why are the physical processes in our brain accompanied by the qualitative (or phenomenal) feel? The mere qualitative feel or qualia are those to be explained. The originator of the problem’s name is the Australian philosopher David Chalmers who divided the problems of consciousness into the (...) ‘easy’ problems and the ‘hard’ problem. The former are ‘easy’ because they can be functionally explained. The ‘hard’ problem, in its turn, cannot. From this, it follows that the explanation of the hard problem of consciousness must be found elsewhere. Chalmers’ nonreductive theory of consciousness (or naturalistic dualism) is a serious candidate for a such-like explanation. In general, it suggests conscious experience as one of the fundamental features of our world, together with such fundamental world features as mass, charge etc. It is a general overview of David Chalmers’ philosophy of mind that is carrying out in the proposed paper. Key words: the ‘easy’ problems and the ‘hard’ problem of consciousness, the phenomenal and psychological concepts of mind, awareness, experience, something it is like, qualia, supervenience, zombie, naturalistic dualism, the principle of structural coherence, the principle of organizational invariance, the double-aspect theory of information.

This thesis investigates the relationship between consciousness and self-consciousness. I consider two broad claims about this relationship: a constitutive claim, according to which all conscious experiences constitutively involve self-consciousness; and a typicalist claim, according to which ordinary conscious experiences contingently involve self-consciousness. Both of these claims call for elucidation of the relevant notions of consciousness and self-consciousness. -/- In the first part of the thesis ('The Myth of Constitutive Self-Consciousness'), I critically examine the constitutive claim. I start by offering an (...) elucidatory account of consciousness, and outlining a number of foundational claims that plausibly follow from it. I subsequently distinguish between two concepts of self-consciousness: consciousness of one's experience, and consciousness of oneself (as oneself). Each of these concepts yields a distinct variant of the constitutive claim. In turn, each resulting variant of the constitutive claim can be interpreted in two ways: on a 'minimal' or deflationary reading, they fall within the scope of foundational claims about consciousness, while on a 'strong' or inflationary reading, they point to determinate aspects of phenomenology that are not acknowledged by the foundational claims as being aspects of all conscious mental states. I argue that the deflationary readings of either variant of the constitutive claim are plausible and illuminating, but would ideally be formulated without using a term as polysemous as 'self-consciousness'; by contrast, the inflationary readings of either variant are not adequately supported. -/- In the second part of the thesis ('Self-Consciousness in the Real World'), I focus on the second concept of self-consciousness, or consciousness of oneself as oneself. Drawing upon empirical evidence, I defend a pluralist account of self-consciousness so construed, according to which there are several ways in which one can be conscious of oneself as oneself – through conscious thoughts, bodily experiences and perceptual experiences – that make distinct determinate contributions to one's phenomenology. This pluralist account provides us with the resources to vindicate the typicalist claim according to which consciousness of oneself as oneself – a sense of self – is pervasive in ordinary conscious experiences, as a matter of contingent empirical fact. It also provides us with the resources to assess the possibility that a subject might be conscious without being conscious of herself as herself in any way. (shrink)

It is widely assumed that ordinary conscious experience involves some form of sense of self or consciousness of oneself. Moreover, this claim is often restricted to a 'thin' or 'minimal' notion of self-consciousness, or even 'the simplest form of self-consciousness', as opposed to more sophisticated forms of self-consciousness which are not deemed ubiquitous in ordinary experience. These formulations suggest that self-consciousness comes in degrees, and that individual subjects may differ with respect to the degree of self-consciousness they exhibit at a (...) given time. In this article, I critically examine this assumption. I consider what the claim that self-consciousness comes in degrees may mean, raise some challenges against the different versions of the claim, and conclude that none of them is both coherent and particularly plausible.

Consider the following argument If panpsychism is true, then the hard problem of consciousness is solved Physicalism is true Physicalism entails panpsychism. We conclude that The hard problem of consciousness is solved. This is a valid argument, and one whose conclusion has a certain appeal. What about the premisses? How exactly is panpsychism a solution to the problem of phenomenal consciousness? Who can take panpsychism seriously, and how can panpsychism be entailed by physicalism? A little forcing is assumed in suggesting (...) to consider a philosophical argument whose conclusion is panpsychism. But I think the exercise is worthwhile, provided we spell out all the consequences of forcing. (shrink)

The proper task of philosophy is to keep alive awareness of what our most fundamental, important, urgent problems are, what our best attempts are at solving them and, if possible, what needs to be done to improve these attempts. Unfortunately, academic philosophy fails disastrously even to conceive of the task in these terms. It makes no attempt to ensure that universities tackle global problems - global intellectually, and global in the sense of concerning the future of the earth and humanity. (...) Universities do not give sustained attention to global problems (due to specialization and giving priority to the pursuit of knowledge) and as a result violate three of the four most elementary rules of rational problem solving conceivable. Judged from the standpoint of helping humanity tackle global problems, universities as at present constituted betray reason and, as a result, betray humanity. Bereft of institutions of learning rationally designed to help us make progress towards as good and wise a world as possible, not surprisingly we fail to learn how to do it. This is the key crisis of our times. And it is, at root, a failure of philosophy. It is the failure of philosophy to keep alive rational exploration of global problems in universities, and in the public domain - a failure that can be traced back to the origins of modern philosophy in the 17th century. We urgently need a revolution in philosophy so that academic philosophers take up their proper task of promoting rational exploration of our fundamental, global problems. (shrink)

Philosophy of science is seen by most as a meta-discipline – one that takes science as its subject matter, and seeks to acquire knowledge and understanding about science without in any way affecting, or contributing to, science itself. Karl Popper’s approach is very different. His first love is natural philosophy or, as he would put it, cosmology. This intermingles cosmology and the rest of natural science with epistemology, methodology and metaphysics. Paradoxically, however, one of his best known contributions, his proposed (...) solution to the problem of demarcation, helps to maintain the gulf that separates science from metaphysics, thus fragmenting cosmology into falsifiable science on the one hand, untestable philosophy on the other. This has damaging repercussions for a number of issues Popper tackles, from the problem of induction to simplicity of theory and quantum theory. But his proposed solution to the demarcation problem is untenable. Metaphysical assumptions are an integral part of scientific knowledge, inherent in the persistent acceptance of unified theories against the evidence. Once this is appreciated, it becomes obvious that natural philosophy, a synthesis of science and philosophy, is both more rigorous and of greater intellectual value than the two dissociated components we have today. What Popper sought for could come to full fruition. Problems that Popper tackled, from the problem of induction, to the problem of unity of theory, problems of quantum theory, and problems concerning the scope and limits of physics, all receive more adequate resolution within the new, fully-fledged natural philosophy.

Ordinary Language Philosophy has largely fallen out of favour, and with it the belief in the primary importance of analyses of ordinary language for philosophical purposes. Still, in their various endeavours, philosophers not only from analytic but also from other backgrounds refer to the use and meaning of terms of interest in ordinary parlance. In doing so, they most commonly appeal to their own linguistic intuitions. Often, the appeal to individual intuitions is supplemented by reference to dictionaries. In recent times, (...) Internet search engine queries for expressions of interest have become quite popular. Apparently, philosophers attempt to surpass the limits of their own linguistic intuitions by appealing to experts or to factual uses of language. I argue that this attempt is commendable but that its execution is wanting. Instead of appealing to dictionaries or Internet queries, philosophers should employ computer-based linguistic corpora in order to confirm or falsify hypotheses about the factual use of language. This approach also has some advantages over methods employed by experimental philosophers. If the importance of ordinary language is stressed, the use of linguistic corpora is hardly avoidable.

Phenomenal consciousness appears to be particularly normatively significant. For this reason, sentience-based conceptions of ethics are widespread. In the field of animal ethics, knowing which animals are sentient appears to be essential to decide the moral status of these animals. I argue that, given that materialism is true of the mind, phenomenal consciousness is probably not particularly normatively significant. We should face up to this probable insignificance of phenomenal consciousness and move towards an ethic without sentience.

Distributive egalitarians believe that distributive justice is to be explained by the idea of distributive equality (DE) and that DE is of intrinsic value. The socio-relational critique argues that distributive egalitarianism does not account for the “true” value of equality, which rather lies in the idea of “equality as a substantive social value” (ESV). This paper examines the socio-relational critique and argues that it fails because – contrary to what the critique presupposes –, first, ESV is not conceptually distinct from (...) DE, and second, the idea of ESV cannot serve as a “foundation” or “root” of distributive egalitarianism. (shrink)

Delusions and hallucinations present a challenge to traditional epistemology by allowing two people’s experiences of the world to be vastly different to each other. Traditional objective realism assumes that there is a mind-independent objective world of which people gain knowledge through experience. However, each person only has direct access to his or her own subjective experience of the world, and so neither can be certain that his or her experience represents an objective world more accurately than the other’s. This essay (...) proposes an intersubjective account of psychosis, which avoids this sceptical attack on objective certainty by considering reality not at the level of an objective mindindependent world, but at the level of peoples’ shared experiences. This intersubjective hypothesis is developed further, with reference to Husserl’s concept of multiple lifeworlds, into a relativistic account. The implication on the social role of psychiatry is also explored. (shrink)

This paper is an overview of recent discussions concerning the mind–body problem that have been taking place at the interface between philosophy and neuroscience. In it I focus on phenomenal consciousness or “qualia”, which I distinguish from various related issues (sections 1-2). I then discuss various influential skeptical arguments that question the possibility of reductive explanations of qualia in physicalist terms: knowledge arguments, conceivability arguments, the argument from multiple realizability and the explanatory gap argument. None of the arguments is found (...) entirely convincing (section 3). It does not necessarily follow that reductive physicalism is the only option, but it is defensible. However, constant conceptual and methodological reflection is required alongside ongoing research, to keep such a view free from dogmatism and naivety (section 4). (shrink)

Chalmers argues that ideal conceivability (conceivability on ideal rational reflection) entails possibility and on this basis assumes that zombies are possible and, therefore, that materialism is false. I argue that the paradigm cases of conceivability intuitions that Chalmers takes to be reliable guides to possibility are not only conceptually coherent, even on ideal rational reflection, but in addition have some rational explanation. The conceivability of zombies, however, has no rational explanation. So it is not ad hoc to deny that the (...) conceivability of zombies entails possibility. (shrink)

The Integrated Information Theory (IIT) formulated for the first time in 2004 by the neuroscientist Giulio Tononi, is a theoretical framework aiming to scientifically explain phenomenal consciousness. The IIT is presented in the first part of this work. Broadly speaking, integrated information is an abstract quantitative measure of the causal power a system has on itself. The main claim of IIT is the identity between informational structures and experience. The nature of this identity will be the subject of the second (...) part. One can interpret the IIT as a fundamental law of nature connecting the physical domain to the mental domain. The philosophical implications of such a claim are numerous and they are subject to criticism. This will be the main concern of the third and last part. (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)

The aim of this article is to examine and defend videogame cognitivism (VC). According to VC, videogames can be a source of cognitive successes (such as true beliefs, knowledge or understanding) for their players. While the possibility of videogame-based learning has been an extensive topic of discussion in the last decades, the epistemological underpinnings of these debates often remain unclear. I propose that VC is a domain- specific brand of aesthetic cognitivism, which should be carefully distinguished from other views that (...) also insist on the cognitive or educational potential of videogames. After these clarifications, I discuss and assess different broad strategies to motivate VC: propositionalism, experientialism, and neocognitivism. These map the different ways in which videogames can prove epistemically valuable, showing them to be, respectively, sources of propositional knowledge, experiential knowledge, and understanding. I eventually argue that neocognitivism is a particularly promising and yet underexplored way to defend VC. (shrink)

Each well-known proposed solution to the mind-body problem encounters an impasse. These take the form of an explanatory gap, such as the one between mental and physical, or between micro-subjects and macro-subject. The dialectical pressure to bridge these gaps is generating positions in which consciousness is becoming increasingly foundational. The most recent of these, cosmopsychism, typically casts the entire cosmos as a perspectival subject whose mind grounds those of more limited subjects like ourselves. I review the dialectic from materialism and (...) dualism through to panpsychism, suggesting that explanatory gaps in the latter stem from assuming foundational consciousness to be perspectival. Its renunciation may yield the notion of an aperspectival, universal, “non-dual” consciousness that grounds all manifestation and is unstructured by subject, object or any differentia. Not only is such consciousness suggestive of a natural successor to cosmopsychism, but it has also been reported to be the direct experience of mystics who claim to have transcended the individual perspective. Their purported insight — that our aperspectival conscious nature is identical to the ground of all being — has been termed “the Perennial Philosophy”. Believing this Perennial Philosophy to offer the most promising way forward in the mind-body problem, I construct from it the foundations of a metaphysical system that I call “Perennial Idealism”. This attempts to account for manifestation in terms of dispositional, imagery-bound subjects. I then address an age-old “Parmenidean” conundrum that I refer to as “the problem of the one and the many”: How can an undifferentiated substratum ground differentia without the ground itself differentiating? The proposed solution takes its cue from mystico-philosophical writings in the Advaita Vedānta tradition, known as the ajāta doctrine. (shrink)

The inherently subjective nature of consciousness severely limits our ability to make progress on the problem of consciousness. The inability to acquire objective, publicly available data on the phenomenal aspect of consciousness makes evaluating alternative theories very difficult, if not impossible. However, the anomalous nature of subjective states with respect to our conventional theories of the physical world suggests the possibility of considering other anomalous data around consciousness that happen to be objective. For such purposes, I propose that we examine (...) the psi data gathered under laboratory conditions, which generally receive little attention. I wish to consider whether we have theories or frameworks of consciousness that attempt to account for subjective qualia but also fit the psi data. I argue that Russellian monism can be combined with an argument regarding quantum holism to arrive at a version of cosmopsychism that fits very well with the psi data. While I do not argue that such a framework exhausts the theoretical possibilities, I do suggest we can move forward with a framework that has attractive theoretical features and is also consistent with objective data currently on the table.

This chapter reviews some interesting research trends in the philosophy of information (PI). First, PI is defined; then, a series of open problems in PI on which philosophers are currently working is considered. The conclusion highlights the innovative character of this new area of research.

Jaegwon Kim’s (2005) most recent formulation of the so-called Supervenience Argument against Non-Reductive Physicalism is discussed. The two stages of Kim’s argument can be seen as instances of, what I will call, the Generalized Exclusion Argument.

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)

This paper aims to clarify the relationship between consciousness and attention through theoretical considerations about evolution. Specifically, we will argue that the empirical findings on attention and the basic considerations concerning the evolution of the different forms of attention demonstrate that consciousness and attention must be dissociated regardless of which definition of these terms one uses. To the best of our knowledge, no extant view on the relationship between consciousness and attention has this advantage. Because of this characteristic, this paper (...) presents a principled and neutral way to settle debates concerning the relationship between consciousness and attention, without falling into disputes about the meaning of these terms. A decisive conclusion of this approach is that extreme views on the relationship between consciousness and attention must be rejected, including identity and full dissociation views. There is an overlap between the two within conscious attention, but developing a full understanding of this mechanism requires further empirical investigations. (shrink)

In regard to the explanation of actions that are governed by institutional rules, John R. Searle introduces the notion of a mental “background” that is supposed to explain how persons can acquire the capacity of following such rules. I argue that Searle’s internalism about the mind and the resulting poverty of his conception of the background keep him from putting forward a convincing explanation of the normative features of institutional action. Drawing on competing conceptions of the background of Heidegger and (...) Wittgenstein, I propose to revise Searle’s conception. The background of institutional agency can only provide a convincing explanation if it includes the context of actions and intersubjective structures of a shared life-world. I suggest that a further development of this idea would lead to the identification of the background with a web of social recognition. (shrink)

Deferential Monadic Panpsychism is a view that accepts that physical science is capable of discovering the basic structure of reality. However, it denies that reality is fully and exhaustively de- scribed purely in terms of physical science. Consciousness is missing from the physical description and cannot be reduced to it. DMP explores the idea that the physically fundamental features of the world possess some intrinsic mental aspect. It thereby faces a se- vere problem of understanding how more complex mental states (...) emerge from the mental features of the fundamental features. Here I explore the idea that a new form of aggregative emergence, which I call 'combinatorial infusion', could shed light on this problem and bolster the prospects for this form of panpsychism.
