The thesis examines the theoretical relationship between law and ethics. Its methodology is informed by both the existentialist tradition of ethical phenomenology and the natural law tradition in legal theory. The main claim of the thesis is that a phenomenological analysis of ethical experience, as suggested by the writings of existentialist authors such as Jean-Paul Sartre and Emmanuel Levinas, provides important support for the natural law tradition. This claim is developed and defended through detailed engagement with the natural law theory (...) of John Finnis. Specifically, I contend that Finnis’ account of moral reasoning as applying the principles of practical reasonableness to a context of self-evident, basic values gains significant support from a phenomenological theory of ethical experience. Finnis’ emphasis on the irreducible role of choice in moral deliberation also finds support in the existentialist tradition. However, I criticise some key aspects of Finnis’ theory, including his emphasis on the transcendental character of the basic values and his account of legal obligation. I begin by outlining some central features of the existentialist approach to philosophy. I advance an interpretation of existentialism as ethical phenomenology. I then discuss some possible methodological connections between the existentialist and natural law traditions. This discussion provides the methodological framework for the remainder of the thesis. The thesis develops and defends a substantially original theory of the relationships between law, ethics and politics. The exposition begins with an account of the relationship between law and community that draws upon the work of Finnis and G. W. F. Hegel. I then outline a phenomenological theory of ethical experience, drawing in particular on the writings of Sartre and Levinas. I employ this phenomenological account of ethics to develop a conception of moral reasoning as reflective, good faith engagement with pre-reflective social judgements of ethical significance. This view of ethical experience and moral reasoning is then used as the basis for an examination of the concept of law and its relationship to political discourse. I turn next to the notions of legal authority and obligation. I argue that law, in the focal sense of the term, presents a generic, peremptory obligation that is necessarily moral in character. In the course of the argument, I critically discuss the conceptions of legal authority proposed by Joseph Raz, Adolf Reinach, H. L. A. Hart, John Rawls, Finnis, Jacques Derrida and Hans Kelsen. This view of legal obligation entails there are fundamental moral conditions that positive rules must satisfy to qualify as law, in the focal sense. I explore the nature of the moral framework created by these conditions through a detailed analysis of the ethical foundations of political discourse. I argue that political discourse is founded upon an ontological apprehension of the nature of humans as free, ethical beings, which finds expression in a developed notion of political freedom. I suggest that the distinction between positive and negative forms of freedom advanced by Isaiah Berlin is best understood in terms of the different types of political claims invoked by those conceptions. I develop this theory by reference to the work of Charles Taylor, Gerald C. MacCallum, Wesley Newcomb Hohfeld, W. D. Ross, Robert Nozick and F. A. Hayek. I conclude by discussing the role of ethical experience in the interpretation of legal materials. I argue that ethical judgements play an irreducible role in constructing the natural interpretive context for judicial reasoning. I engage with the work of Hart, Lon L. Fuller, Martin Heidegger, Hans-Georg Gadamer, Ferdinand de Saussure and Ronald Dworkin, among others. In the final substantive chapter of the thesis, the potential for ethical judgements to play a constructive role in judicial action is illustrated through a detailed discussion of the doctrine of government neutrality.

Radical skepticism relies on the hypothesis that one could be completely cut off from the external world. In this paper, I argue that this hypothesis can be rationally motivated by means of a conceivability argument. Subsequently, I submit that this conceivability argument does not furnish a good reason to believe that one could be completely cut off from the external world. To this end, I show that we cannot adequately conceive scenarios that verify the radical skeptical hypothesis. Attempts to do (...) so fall prey to one or another of three pitfalls: they end up incomplete, reveal a deep contradiction or recreate a non-skeptical hypothesis. I use these results to improve upon Pritchard’s recent attempt at undercutting radical skepticism. (shrink)

The thesis is intended to contribute to the growing understanding of the indispensable role played by phenomenal consciousness in human cognition, and specifically in making our concepts of the external world available. The focus falls on so called observational concepts, a type of rudimentary, perceptually-based objective concepts in our repertoire — picking out manifest properties such as colors and shapes. A theory of such concepts gets provided, and, consequently, the exact role that perceptual consciousness plays in making concepts of this (...) sort available gets settled. In the first half of the thesis, observational concepts get construed as a special type of recognitional concepts. On an analogy with perceptual demonstratives, having such concepts would involve having non-trivial knowledge of their reference. The experiential basis of such concepts would, among other things, provide for such constitutive knowledge. The theoretical background relevant to the hypothesis gets provided in the first chapter. A defence of the hypothesis follows in the second. In the second half of the thesis, care is taken to distinguish among two ways in which the constitutive knowledge of the reference of an observational concept could be fleshed out. In the third chapter, perceptual experience is shown to provide the basis both for knowledge of observational properties by acquaintance, and for knowledge of the essence of such properties — provided that knowledge of essence gets construed in the right, modest way. It might be natural to take knowledge by acquaintance to be the sort relevant to observational concept possession, especially given that in the case of perceptual demonstratives this is the role likely played by experience. However, this initial impression proves to be mistaken. The constitutive knowledge of the referent of an observational concept turns out to consist in the capacity to determine a priori the essence of the respective property. To show this, an argument gets provided in the penultimate fourth chapter, based on the key role played by experiences of instances of observational properties in optimal viewing conditions in enabling the possession of the respective observational concept.

Imagism about Phenomenal Thought is (roughly) the view that there is some concept *Q* (for some sensory quality Q) that we can employ only while we experience the quality Q. I believe this view is theoretically significant, is or can be made intuitively appealing, and is explicitly or implicitly accepted by many contemporary philosophers However, there is no good reason to accept it. Or so I argue.

What is the mind? Is consciousness a process in the brain? How do our minds represent the world? Philosophy of Mind: Classical and Contemporary Readings is a grand tour of writings on these and other perplexing questions about the nature of the mind. The most comprehensive collection of its kind, the book includes sixty-three selections that range from the classical contributions of Descartes to the leading edge of contemporary debates. Extensive sections cover foundational issues, the nature of consciousness, and the (...) nature of mental content. Three of the selections are published here for the first time, while many other articles have been revised especially for this volume. Each section opens with an introduction by the editor. Philosophy of Mind is suitable for students at all levels and also for general readers. (shrink)

I identify one particular strand of thought in Thomas Nagel's ‘What Is It Like to Be a Bat?’, which I think has helped shape a certain conception of perceptual consciousness that is still prevalent in the literature. On this conception, perceptual consciousness is to be explained in terms of a special class of properties perceptual experiences themselves exhibit. I also argue that this conception is in fact in conflict with one of the key ideas that supposedly animates Nagel's argument in (...) ‘What Is It Like to Be a Bat?', which is the idea of an intimate connection between the idea of consciousness and that of a point of view.

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)

I develop the relatively familiar idea of a variety of forms of knowledge —not just propositional knowledge but also knowledge -how and experiential knowledge —and show how this variety can be used to make interesting sense of Plato’s and Aristotle’s philosophy, and in particular their ethics. I then add to this threefold analysis of knowledge a less familiar fourth variety, objectual knowledge, and suggest that this is also interesting and important in the understanding of Plato and Aristotle.

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

: Phenomenal knowledge usually comes from experience. But it need not. For example, one could know what it’s like to see red without seeing red—indeed, without having any color experiences. Daniel Dennett (2007) and Pete Mandik (forthcoming) argue that this and related considerations undermine the knowledge argument against physicalism. If they are right, then this is not only a problem for anti‐physicalists. Their argument threatens to undermine any version of phenomenal realism— the view that there are phenomenal properties, or qualia, (...) that are not conceptually reducible to physical or functional properties. I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. This will strengthen the case for physically and functionally irreducible qualia. 2 Phenomenal knowledge usually comes from experience. For example, I know what it’s like to see red because I have done so. Does knowing what it’s like to have an experience with phenomenal character X require having an experience with X? No. A famous counterexample is Hume’s missing shade of blue, in which one can extrapolate from phenomenally similar experiences (A Treatise of Human Nature, Bk. I, Pt. I, Sec. I).1 One might think that a weaker version of the no‐phenomenal‐knowledge‐without‐experience thesis remains tenable, e.g., that knowing what it’s like to see in color requires having or having had color experiences. But this thesis also seems doubtful. Peter Unger (1966) devised plausible counterexamples over four decades ago, and since then others (e.g., Lewis 1988, Alter 1998, Stoljar 2005) have done the same. One could have phenomenal knowledge of color experiences without having such experiences. Indeed, one could have such knowledge without having experiences that are remotely like color experiences. What is the significance of this observation for contemporary debates about consciousness and physicalism? Daniel Dennett (2007) and Pete Mandik (forthcoming) suggest that it undermines the knowledge argument against physicalism.2 That is because they take the claim that someone who has never seen in color could not know what it’s like to see in color to be the basis of the knowledge argument’s main epistemic premise: the premise that (roughly put) 3 no amount of physical knowledge is sufficient for phenomenal knowledge of color experiences. If they are right, then this is not only a problem for anti‐ physicalists. Many physicalists (e.g., Loar 1990/97, Papineau 2002, 2007) accept the knowledge argument’s epistemic premise. Dennett’s and Mandik’s arguments threaten all versions of what David Chalmers (2003) calls phenomenal realism, the view that there are phenomenal properties, or qualia, that are not conceptually reducible to physical or functional properties.3 I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. The net result will be to strengthen the case for physically inexplicable qualia. (shrink)

There are two competing views of knowledge-how: Intellectualism and anti-intellectualism. According to the reductionist varieties of intellectualism defended by Jason Stanley and Timothy Williamson (2001) and Berit Brogaard (2007, 2008, 2009), knowledge-how simply reduces to knowledge-that. To a first approximation, s knows how to A iff there is a w such that s knows that w is a way to A. For example, John knows how to ride a bicycle if and only if there is a way w such that (...) John knows that w is a way to ride a bicycle. John Bengson and Marc Moffett (2007) defend an anti-reductionist version of intellectualism which takes knowledge-how to require, in addition, that s understand the concepts involved in her belief. According to the anti-intellectualist accounts originally defended by Gilbert Ryle (1946) and many others after him, knowledge-how requires the possession of a practical ability and so knowing that w (for some w) is a way to A does not suffice for knowing-how. For example, John knows how to ride a bicycle only if John has the ability to ride it; if John merely knows that w (for some w) is a way to ride a bicycle, John does not know how to ride a bicycle. Here I will argue for a conciliatory position that is compatible with the reductionist variety of intellectualism: knowledge-how is reducible to knowledge-that. But, I argue, there are knowledge states which are not justification-entailing and knowledge states which are not belief-entailing. Both kinds of knowledge state require the possession of practical abilities. I conclude by arguing that the view defended naturally leads to a disjunctive conception of abilities as either essentially involving mental states or as not essentially involving mental states. Only the former kind of ability is a kind of knowledge-state, viz. a knowledge-how state. (shrink)

Frank Jackson endorses epiphenomenalism because he thinks that his knowledge argument undermines physicalism. One of the most interesting criticisms of Jackson's position is what I call the 'inconsistency objection'. The inconsistency objection says that Jackson's position is untenable because epiphenomenalism undermines the knowledge argument. The inconsistency objection has been defended by various philosophers independently, including Michael Watkins, Fredrik Stjernberg, and Neil Campbell. Surprisingly enough, while Jackson himself admits explicitly that the inconsistency objection is 'the most powerful reply to the knowledge (...) argument' he knows of, it has never been discussed critically. The aim of this paper is to evaluate the objection and to identify and consider its implications. The objection is alleged to be based on a causal theory of knowledte. I argue that the objection fails by showing that any causal theory of knowledge is such that it is either false or does not support the inconsistency objection. In order to defend my argument, I offer a hypothesis concerning phenomenal knowledge. (shrink)

O'Brien & Opie's (O&O's) theory demands a view of unconscious processing that is incompatible with virtually all current PDP models of neural activity. Relative to the alternatives, the theory is closer to an AI than a parallel distributed processing (PDP) perspective, and its treatment of phenomenology is ad hoc. It raises at least one important question: Could features of network relaxation be the “switch” that turns an unconscious into a conscious network?

I outline and develop a particular physicalist perspective on qualia, and suggest that it may be the basis of a correct account of the relationship of mental states to the physical world. Assume that a quale is a perspective on a physical state in the organism – the reality as known as distinct from the reality as such – but that the perspective, though it entails irreducible experiential knowledge, has no physical substance over that encompassed in the physical state itself. (...) Assume this physical state is also a brain state. The position is a useful one. First, reductionist physicalism is true, but experiential qualities are irreducible physical knowledge, and a required part of our physical world view. Second, experiences are not additional problems over those addressed externally, but only how these problems seem when known internally – an experience just is the physical state that underlies its external counterpart, and the same standard scientific account suffices to explain both, permitting a science of consciousness to develop by applying the same standard external–observer–based methods adopted in older scientific disciplines. Finally, challenges to physicalism associated with the ‘unbridgeable gap’, Leibniz's Law, Jackson's knowledge argument, and Chalmers' hard problem of consciousness are successfully countered.

Functionalism in the philosophy of mind is the doctrine that what makes something a mental state of a particular type does not depend on its internal constitution, but rather on the way it functions, or the role it plays, in the system of which it is a part. This doctrine is rooted in Aristotle's conception of the soul, and has antecedents in Hobbes's conception of the mind as a “calculating machine”, but it has become fully articulated (and popularly endorsed) only (...) in the last third of the 20th century. Though the term ‘functionalism’ is used to designate a variety of positions in a variety of other disciplines, including psychology, sociology, economics, and architecture, this entry focuses exclusively on functionalism as a philosophical thesis about the nature of mental states.

You know that George W. Bush is the U.S. president, but you know how to ride a bicycle. What's the difference? According to intellectualists, not much: either knowing how to do something is a matter of knowing that something is the case or, at the very least, know-how requires a prior bit of theoretical knowledge. Anti-intellectualists deny this order of priority: either knowing-how and knowing-that are independent or, at the very least, knowing that something is the case requires a prior (...) bit of know-how. Much of the dispute centers on the relationship between knowing how to do something and having an ability to do it. If having an ability is necessary and sufficient for knowing-how, this is thought to provide comfort for anti-intellectualists. This paper traces the place of ability in the know-how/know-that debate from Ryle's seminal statement of anti-intellectualism through Stanley and Williamson's more recent defense of intellectualism.

The purpose of this paper is to raise some questions about the idea, which was first made prominent by Gilbert Ryle, and has remained associated with him ever since, that there are at least two types of knowledge (or to put it in a slightly different way, two types of states ascribed by knowledge ascriptions) identified, on the one hand, as the knowledge (or state) which is expressed in the ‘knowing that’ construction (sometimes called, for fairly obvious reasons, ‘propositional’ or (...) ‘factual’ knowledge) and, on the other, as the knowledge (or state) which is ascribed in the ‘knowing how’ construction (sometimes called ‘practical’ knowledge). This idea, which might be said to be Ryle's most lasting philosophical legacy, has, in some vague form, remained part of conventional wisdom in philosophy since he put it forward. My purpose here is fairly accurately described as ‘raising questions’, since both the criticisms of the received view (as I interpret it), and the positive alternative suggestions to be advanced, are, to some extent, tentative and exploratory. The aim is to assemble a broad range of evidence for the conclusion that we need to replace the standard account, to query especially what Ryle suggested as evidence for it, and to explore what seems to me to be the indicated replacement for it.

Cognitive science has wholeheartedly embraced functional brain imaging, but introspective data are still eschewed to the extent that it runs against standard practice to engage in the systematic collection of introspective reports. However, in the case of executive processes associated with prefrontal cortex, imaging has made limited progress, whereas introspective methods have considerable unfulfilled potential. We argue for a re-evaluation of the standard ‘cognitive mapping’ paradigm, emphasizing the use of retrospective reports alongside behavioural and brain imaging techniques. Using all three (...) sources of evidence can compensate for their individual limitations, and so triangulate on higher cognitive processes. (shrink)

We spend our lives protecting an elusive self - but does the self actually exist? Drawing on literature from Western philosophy, neuroscience and Buddhism (interpreted), the author argues that there is no self. The self - as unified owner and thinker of thoughts - is an illusion created by two tiers. A tier of naturally unified consciousness (notably absent in standard bundle-theory accounts) merges with a tier of desire-driven thoughts and emotions to yield the impression of a self. So while (...) the self, if real, would think up the thoughts, the thoughts, in reality, think up the self. (shrink)

Physicalism is the thesis that everything is physical, or as contemporary philosophers sometimes put it, that everything supervenes on, or is necessitated by, the physical. The thesis is usually intended as a metaphysical thesis, parallel to the thesis attributed to the ancient Greek philosopher Thales, that everything is water, or the idealism of the 18th Century philosopher Berkeley, that everything is mental. The general idea is that the nature of the actual world (i.e. the universe and everything in it) conforms (...) to a certain condition, the condition of being physical. Of course, physicalists don't deny that the world might contain many items that at first glance don't seem physical — items of a biological, or psychological, or moral, or social nature. But they insist nevertheless that at the end of the day such items are either physical or supervene on the physical. (shrink)

Feelings and experiences vary widely. For example, I run my fingers over sandpaper, smell a skunk, feel a sharp pain in my finger, seem to see bright purple, become extremely angry. In each of these cases, I am the subject of a mental state with a very distinctive subjective character. There is something it is like for me to undergo each state, some phenomenology that it has. Philosophers often use the term ‘qualia’ (singular ‘quale’) to refer to the introspectively accessible, (...) phenomenal aspects of our mental lives. In this standard, broad sense of the term, it is difficult to deny that there are qualia. Disagreement typically centers on which mental states have qualia, whether qualia are intrinsic qualities of their bearers, and how qualia relate to the physical world both inside and outside the head. The status of qualia is hotly debated in philosophy largely because it is central to a proper understanding of the nature of consciousness. Qualia are at the very heart of the mindbody problem.

A phenomenal concept is the concept of a particular type of sensory or perceptual experience, where the notion of experience is understood phenomenologically. A recent and increasingly influential idea in philosophy of mind suggests that reflection on these concepts will play a major role in the debate about conscious experience, and in particular in the defense of physicalism, the thesis that psychological truths supervene on physical truths. According to this idea—I call it the phenomenal concept strategy —phenomenal concepts are importantly (...) different from other concepts, and arguments against physicalism fatally neglect to take this difference into account. This paper divides the phenomenal concept strategy into a number of different versions, and argues that no version of the strategy is successful. The paper ends by contrasting the phenomenal concept strategy with a rival strategy—I call it the missing concept strategy . I suggest that the missing concept strategy presents a more plausible response to the issues about physicalism and experience. (shrink)

Frank Jackson’s knowledge argument is a very influential piece of reasoning that seeks to show that colour experiences constitute an insoluble problem for science. This argument is based on a thought experiment concerning Mary. She is a vision scientist who has complete scientific knowledge of colours and colour vision but has never had colour experiences. According to Jackson, upon seeing coloured objects, Mary acquires new knowledge that escapes her complete scientific knowledge. He concludes that there are facts concerning colour experiences (...) that scientific knowledge can neither describe nor explain. Specifically, these facts involve the occurrence of certain non-physical properties of experiences that he calls qualia. The present research considers whether a plausible formulation of the hypothesis that science can accommodate colour experiences is threatened by a version of the knowledge argument. The specific formulation of this problem has two motivations. Firstly, before investigating whether the knowledge argument raises a problem for the claim that science can account for colour experiences, we need a plausible formulation of this claim. I argue that the idea that science can accommodate colour experiences can be formulated as the modest reductionism hypothesis. Roughly speaking, this is the hypothesis that a science that can be explanatory interfaced with current physics of ordinary matter can account for conscious experiences. Secondly, an unintelligible premise figures in Jackson’s version the knowledge argument. Namely, it is assumed that Mary possesses a complete scientific knowledge. Nevertheless, the type of strategy involved in Jackson’s argument can be used to target modest reductionism. By considering contemporary psychophysics and neuroscience, I characterise Mary’s scientific knowledge. First, this characterisation is intelligible. In fact, it is elaborated on the basis of descriptions and explanations of colour experiences involved in current physics and neuroscience. Second, a supporter of modest reductionism can assume that the scientific knowledge ascribed to Mary might account for colour experiences. The main conclusion of the present research is that our version of the knowledge argument fails to threaten the modest reductionism hypothesis. In fact, I endorse what can be called the “two ways of thinking” reply to the knowledge argument. According to this response, the knowledge argument shows that there are different ways of thinking about colour experiences. One way of thinking is provided by scientific knowledge. The other way of thinking is provided by our ordinary conception of colour experiences. However, the existence of these two ways of thinking does not imply the existence of facts and properties that escape scientific knowledge. It might be the case that the ordinary way of thinking about colour experience concerns facts and properties described and explained by science. The principal conclusion of the research results from two investigations. The first line of research aims to reveal and evaluate the implicit assumptions that figure in the knowledge argument. The main body of the research is dedicated to this task. The principal result of this investigation is that the knowledge argument must rely on an account of introspective knowledge of colour experiences. I argue that an inferential model of introspection provides such account. On this model, Mary’s capacity to hold beliefs about her colour experiences when she sees coloured objects requires her mastery of colour concepts. The second main investigation seeks to justify the two ways of thinking strategy. As many opponents and supporters have recently started to realise, this strategy might be charged with being ad hoc. I offer a distinctive justification of this reply to the knowledge argument. Assuming the account of introspection mentioned above, the existence of visual recognitional colour concepts might justify this strategy. A person possesses these concepts when she is able to determine the colours of objects simply by having visual experiences. (shrink)

This paper is trying to show that it is not possible to use the Knowledge argument as independent evidence for the form of non-reductionism the Modal argument argues for. To show this, Jackson's famous 'Mary' thought experiment is imagined in a zombie world. This leads to the result that there are many problems in the Mary experiment, which cannot have anything to do with phenomenal Qualia, because the Zombie-Mary would encounter them as well, and once all these problems are accounted (...) for, it is no longer clear whether a Zombie-Mary is conceivable at all. Finally, an alternative explanation for the strong non-reductive intuitions of the Mary experiment is discussed. (shrink)

I defend Frank Jackson's knowledge argument against physicalism in the philosophy of mind from a criticism that has been advanced by Laurence Nemirow and David Lewis. According to their criticism, what Mary lacked when she was in her black and white room was a set of abilities; she did not know how to recognize or imagine certain types of experience from a first-person perspective. Her subsequent discovery of what it is like to experience redness amounts to no more than her (...) acquisition of these abilities. The physicalist can admit this, since it does not commit one to the view that there are any facts of which Mary was ignorant . I argue against this view, on the grounds that the knowledge of what an experience is like cannot be equated with the possession of any set of abilities. (shrink)

This paper calls into question the viability of materialist reduction of the phenomenal. I revisit the 'Knowledge Argument', which claims that there is information about the phenomenal which is not reducible to, nor even inferable from, information about the physical. I demonstrate the failure of the two chief strategies for blocking the Knowledge Argument: analyzing phenomenal knowledge as an ability, and construing it as knowledge of facts which are ontologically reducible to physical facts. Materialist reduction of the phenomenal is, thus, (...) untenable; materialists must adopt a more extreme, eliminativist view about the phenomenal. (shrink)

Mary learns all the physical facts that one can learn by watching lectures on black-on-white television. According to Jackson, Mary learns new facts when she leaves the room and has color experiences, and that this undermines physicalism. Physicalists have responded by denying the new facts thesis; they argue, she acquires abilities, acquaintance knowledge, or new guises. I argue that the NFT is more plausible than any of the proposed alternatives. I also argue that the NFT does not undermine physicalism unless (...) physicalism entails that all physical facts are discursively learnable, and that the latter entailment is questionable. (shrink)

The explicit aim of Daniel Dennett’s new paper ‘What RoboMary Knows’ is to show that Mary will necessarily be able to come to know what it is like to see in colour, if she fully understands all the physical facts about colour vision. I believe we can establish that Dennett’s line of reasoning is flawed, but the flaw is not as simple as an equivocation on ‘knows’. Rather, it goes to the heart of functionalism and hinges on whether or not (...) Dennett is correct to claim that there is ‘no fact of the matter’ about what subjective experience consists in.

Frank Jackson argued, in an astronomically frequently cited paper on 'Epiphenomenal qualia '[Jackson 1982 that materialism must be mistaken. His argument is called the knowledge argument. Over the years since he published that paper, he gradually came to the conviction that the conclusion of the knowledge argument must be mistaken. Yet he long remained totally unconvinced by any of the very numerous published attempts to explain where his knowledge argument had gone astray. Eventually, Jackson did publish a diagnosis of the (...) reasons why, he now thinks, his knowledge argument against materialism fails to prove the falsity of materialism [Jackson 2005. He argues that you can block the knowledge argument against materialism - but only if you tie yourself to a dubious doctrine called representationalism. We argue that the knowledge argument fails as a refutation of either representational or nonrepresentational materialism. It does, however, furnish both materialists and dualists with a successful argument for the existence of distinctively first-person modes of acquaintance with mental states. Jackson's argument does not refute materialism: but it does bring to the surface significant features of thought and experience, which many dualists have sensed, and most materialists have missed.

Many have urged that the biggest obstacles to a physicalistic understanding of consciousness are the problems raised in connection with the subjectivity of consciousness. These problems are most acutely expressed in consideration of the knowledge argument against physicalism. I develop a novel account of the subjectivity of consciousness by explicating the ways in which mental representations may be perspectival. Crucial features of my account involve analogies between the representations involved in sensory experience and the ways in which pictorial representations exhibit (...) perspectives or points of view. I argue that the resultant account of subjectivity provides a basis for the strongest response physicalists can give to the knowledge argument. (shrink)

This study is an exploration of the place of perspectivism in the philosophy of Henri Bergson. His work is compared with that of Thomas Nagel in terms of the mutual concern of these two philosophers to reconcile our increasingly objecti vist and impersonal understanding of reality with the perspectival apprehension of the world that living and conscious beings instantiate. It argues that Bergson's philosophy of time holds the key both to comprehending and to balancing the demands made upon us by (...) these conflicting interests. It is seldom that Bergson's name is thought of in this connection, his concerns more often than not being identified with some thesis about time, movement, or vital forces. One purpose of the present work, therefore, is to contest this interpretive slant, not merely by offering an alternative image of Bergson, but also by critically exploring his employment of perspectivism (both positive and negative). We pursue this goal through the double strategy of both unravelling the inconsistencies in Bergson's· treatment of perspective and separating his own argument from the multitude of myths, opinions, and interpretations, sympathetic and unsympathetic, that have arisen around what is currently understood by "Bergsonism". In retrieving his thought from such philosophical ghettoes as "vitalism," "spiritualism," and "psychologism," we will argue for a Bergsonian perspectivism which ultimately resides in a thesis propounding the primacy of perception. One consequence of this is the demotion of memory's importance within his thought. Not that the orthodox image of Bergsonism that retains the privileged place of memory is wrong. Rather, we argue that there is enough in Bergson's peculiar picture of perception to obviate the need for memory in his philosophy, and, moreover, that it is actually more Bergsonian that memory should be so discharged.

O'Brien & Opie do not address the question of the psychotherapeutic role of unconscious representational states such as beliefs. A dilemma is proposed: if they accept the legitimacy of such states then they should modify what they say about dissociation, and if they do not, they owe us an account of why.

In this paper I discuss a variant of the knowledge argument which is based upon Frank Jackson's Mary thought experiment. Using this argument, Jackson tries to support the thesis that a purely physical – or, put generally: an objectively scientific – perspective upon the world excludes the important domain of `phenomenal' facts, which are only accessible introspectively. Martine Nida-Rümelinhas formulated the epistemological challenge behind the case of Mary especially clearly. I take her formulation of the problem as a starting-point and (...) present a solution which is based solely on the concepts of capability and of metalinguistic beliefs. References to epiphenomenal facts, phenomenal knowledge etc. will be avoided completely. I specify my proposal against the backdrop of Burge's critical reflections about metalinguistic reinterpretation of expressions of belief and the externalist thesis held by Burge, Putnam and others that meanings and mental states are dependent upon the environment. My solution is then compared with Lewis' and Nemirow's ability objection. Finally I argue that the much discussed ``knowing what it is like'' has in its ordinary meaning nothing much to do with `phenomenal knowledge' or knowledge of `epiphenomenal' facts. (shrink)

This book contains a representationalist theory of self-consciousness and of the phenomenal first-person perspective. It draws on empirical data from the cognitive and neurosciences.

How all philosophical explanations of human consciousness and the fundamental structure of the cosmos are bizarre—and why that’s a good thing Do we live inside a simulated reality or a pocket universe embedded in a larger structure about which we know virtually nothing? Is consciousness a purely physical matter, or might it require something extra, something nonphysical? According to the philosopher Eric Schwitzgebel, it’s hard to say. In The Weirdness of the World, Schwitzgebel argues that the answers to these fundamental (...) questions lie beyond our powers of comprehension. We can be certain only that the truth—whatever it is—is weird. Philosophy, he proposes, can aim to open—to reveal possibilities we had not previously appreciated—or to close, to narrow down to the one correct theory of the phenomenon in question. Schwitzgebel argues for a philosophy that opens. According to Schwitzgebel’s “Universal Bizarreness” thesis, every possible theory of the relation of mind and cosmos defies common sense. According to his complementary “Universal Dubiety” thesis, no general theory of the relationship between mind and cosmos compels rational belief. Might the United States be a conscious organism—a conscious group mind with approximately the intelligence of a rabbit? Might virtually every action we perform cause virtually every possible type of future event, echoing down through the infinite future of an infinite universe? What, if anything, is it like to be a garden snail? Schwitzgebel makes a persuasive case for the thrill of considering the most bizarre philosophical possibilities. (shrink)

In his unpublished 1979 Lectures on the Philosophy of Mind, Saul Kripke offers a knowledge argument against materialism focusing on deaf people who lack knowledge of auditory experience. Kripke's argument is a precursor of Frank Jackson's better‐known knowledge argument against materialism (1982). The paper sets out Kripke's argument, brings out its interest and philosophical importance, and explores some similarities and differences between Kripke's knowledge argument and Jackson's.

The contemporary debate around consciousness presents us (and often leads us to embrace) a specific current of thought: physicalism, which states that everything in our reality is physical1. In this paper I want to introduce the main points of the opposite view, dualism, according to which there are two different realms of reality: the mental and the physical one. In the introduction I give the main idea and sketch the general intuition behind dualism. In Section 1 I present substance dualism (...) and its more refined version, which is interactionism. In sub-section 1.1 I describe property dualism, which is the mainstream form of dualism adopted nowadays. In sub-sections 1.1.2 and 1.1.3 are proposed two variations of property dualism: epiphenomenalism and panpsychism. Finally, in Section 2 and its two sub-sections (2.1 and 2.2.) I recall Frank Jackson’s famous 1982 thought experiment and two classical objections to it, which are the Ability Hypothesis and the phenomenal concept strategy one. I conclude with a short reflection if we were to take under consideration the acceptance of dualism as an explanation of consciousness and its nature. PS: there's a mistake at page 12, as there's a note in the middle of the page that is not supposed to be there. (shrink)

The aim of the paper is to recall Frank Jackson's 1982 knowledge argument and some prominent objections that were brought against it. Is there a new path we can take in order to bring something new to the table? Is the debate on the argument and its powerful conclusion over?

David Lewis David Lewis is an American philosopher and one of the last generalists, in the sense that he was one of the last philosophers who contributed to the great majority of sub-fields of the discipline. He made central contributions in metaphysics, the philosophy of language, the philosophy of mind, and probabilistic and practical … Continue reading David Lewis →.

This is the introductory essay to the collection of essays: 'Acquaintance: New Essays' (eds. Knowles & Raleigh, forthcoming, OUP). In this essay I provide some historical background to the concept of acquaintance. I examine various Russellian theses about acquaintance that contemporary acquaintance theorists may wish to reject. I consider a number of questions that acquaintance theorists face. I provide a survey of current debates in philosophy where acquaintance has recently been invoked. And I also provide brief summaries of the other (...) essays in this volume. (shrink)

The hard problem of consciousness has held center stage in the philosophy of mind for the past two decades. It claims that the phenomenal character of conscious experiences—what it’s like to be in them—cannot be explained by appeal to the operation of physiological subsystems. The hard problem arises, however, only given the assumption that hylomorphism is false. Hylomorphism claims that structure is a basic ontological and explanatory principle. A human is not a random collection of physical materials, but an individual (...) composed of physical materials with a structure that accounts for what it is and what it can do—the powers it has. What is true of humans is true of their activities as well. The latter are not random physiological changes, but structured ones: we engage in them by coordinating the ways our parts manifest their powers. Structured activities include perceptual experiences. Consequently, everything about a perceptual experience, including its phenomenal character, can be explained by describing the perceiver’s perceptual subsystems, the powers of those subsystems, and the coordination that unifies their activities into the activity of the perceiver as a whole. Conscious experiences thus fit unproblematically into the natural world—just as unproblematically as the phenomenon of life. Even exponents of the hard problem of consciousness agree that there is no hard problem of life. Consequently, if hylomorphism is true, there can be no hard problem of consciousness. To insist that there is such a problem, then, is implicitly to reject hylomorphism. The concept of consciousness that motivates the hard problem is as much a theoretical construct, therefore, as the concept of life that motivates an obstinate vitalist. (shrink)

Philosophers and psychologists often distinguish episodic or personal memory from propositional or semantic memory. A vexed issue concerns the role, if any, of memory “impressions” or “seemings” within the latter. According to an important family of approaches, seemings play a fundamental epistemological role vis-à-vis propositional memory judgments: it is one’s memory seeming that Caesar was murdered, say, that justifies one’s judgment that he was murdered. Yet, it has been convincingly argued that these approaches lead to insurmountable problems and that memory (...) seemings are not wellsuited to play this justifying role. As a result, many contemporary accounts of propositional memory dispense with these seemings altogether. Is the idea that memory seemings play a key role in propositional memory really the result of bad theorizing? My aim is to shed light on this issue, which I will approach as follows. In Section 1, I contrast episodic memory with propositional memory so as to clarify the nature of the latter. According to the account I put forward, episodic memory consists in the preservation of acquaintance with objects and events, whereas propositional memory consists in the preservation of thought contents. In Section 2, I turn my attention to the contrast between propositional memory contents and propositional memory as an attitude. I argue that they play different roles. Memory contents satisfy a past awareness constraint and a causal constraint; the attitude of remembering explains why we are inclined to endorse these contents. This distinction leads me to explore the attitude of remembering, and I argue, in Section 3, that the most appealing account of this attitude is in terms of feelings of familiarity. In Section 4, I turn my attention to the epistemology of propositional memory and revisit the claim that propositional memory judgments are justifi ed by memory seemings. In so doing, I contend that the attitude of remembering plays an exclusively explanatory role and does not contribute to the epistemology of propositional memory judgments. I conclude by drawing a more general lesson regarding the respective roles of attitudes and contents. (shrink)

The knowledge argument is something that is both an ideal for philosophy and yet surprisingly rare: a simple, valid argument for an interesting and important conclusion, with plausible premises. From a compelling thought-experiment and a few apparently innocuous assumptions, the argument seems to give us the conclusion, a priori, that physicalism is false. Given the apparent power of this apparently simple argument, it is not surprising that philosophers have worried over the argument and its proper diagnosis: physicalists have disputed its (...) validity, or soundness or both; in response, non-physicalists have attempted to reformulate the argument to show its real anti-physicalist lesson.
