This volume of Ned Block's writings collects his papers on consciousness, functionalism, and representationism. A number of these papers treat the significance of the multiple realizability of mental states for the mind-body problem -- a theme that has concerned Block since the 1960s. One paper on this topic considers the upshot for the mind-body problem of the possibility of a robot that is functionally like us but physically different -- as is Commander Data of _Star Trek's_ second generation. The papers (...) on consciousness treat such conceptual issues as phenomenal versus access consciousness, Dennett's theory of consciousness, and the function of consciousness, as well as such empirical matters as "How Not to Find the Neural Correlate of Consciousness," and an argument that there are distinct neural correlates for access consciousness and phenomenal consciousness. Turning to the mind-body problem, Block defends physicalism against Max Black's argument concerning phenomenal modes of presentation. The papers on representationism consider "mental paint" as well as the "Inverted Earth" thought experiment -- a world in which colors are reversed but there is a compensating reversal in the words that are used to describe them. _Consciousness, Function, and Representation_, bringing together papers that have appeared primarily in journals and conference proceedings, can be regarded as Block's most complete statement of his positions on consciousness.

Evaluation of the contribution that Allen Carlson’s environmental aesthetics can make to environmental protection shows that Carlson’s positive aesthetics, his focus on the functionality of human environments for their proper aesthetic appreciation, and his integration of ethical concern with aesthetic appreciation all provide fruitful, though not unproblematic, avenues for an aesthetic defense of theenvironment.

There are two concepts of consciousness that are easy to confuse with one another, access-consciousness and phenomenal consciousness. However, just as the concepts of water and H 2 O are different concepts of the same thing, so the two concepts of consciousness may come to the same thing in the brain. The focus of this paper is on the problems that arise when these two concepts of consciousness are conflated. I will argue that John Searle's reasoning about the function of (...) consciousness goes wrong because he conflates the two senses. And Francis Crick and Christof Koch fall afoul of the ambiguity in arguing that visual area V1 is not part of the neural correlate of consciousness. Crick and Koch's work raises issues that suggest that these two concepts of consciousness may have different neural correlates – despite Crick and Koch's implicit rejection of this idea. (shrink)

This article concerns the interplay between two issues that involve both philosophy and neuroscience: whether the content of phenomenal consciousness is 'rich' or 'sparse', whether phenomenal consciousness goes beyond cognitive access, and how it would be possible for there to be evidence one way or the other.

Representationism 1, as I use the term, says that the phenomenal character of an experience just is its representational content, where that representational content can itself be understood and characterized without appeal to phenomenal character. Representationists seem to have a harder time handling pain than visual experience. I will argue that Michael Tye's heroic attempt at a representationist theory of pain, although ingenious and enlightening, does not adequately come to terms with the root of this difference.

Is consciousness based in prefrontal circuits involved in cognitive processes like thought, reasoning, and memory or, alternatively, is it based in sensory areas in the back of the neocortex? The no-report paradigm has been crucial to this debate because it aims to separate the neural basis of the cognitive processes underlying post-perceptual decision and report from the neural basis of conscious perception itself. However, the no-report paradigm is problematic because, even in the absence of report, subjects might engage in post-perceptual (...) cognitive processing. Therefore, to isolate the neural basis of consciousness, a no-cognition paradigm is needed. Here, I describe a no-cognition approach to binocular rivalry and outline how this approach can help resolve debates about the neural basis of consciousness. (shrink)

The higher order approach to consciousness attempts to build a theory of consciousness from the insight that a conscious state is one that the subject is conscious of. There is a well-known objection1 to the higher order approach, a version of which is fatal. Proponents of the higher order approach have realized that the objection is significant. They have dealt with it via what David Rosenthal calls a “retreat” (2005b, p. 179) but that retreat fails to solve the problem.

One point of view on consciousness is constituted by two claims.

NED HETTINGER | : This essay explores the tension between concern for the suffering of wild animals and concern about massive human influence on nature. It examines Clare Palmer’s animal ethics and its attempt to balance a commitment to the laissez-faire policy of nonintervention in nature with our obligations to animals. The paper contrasts her approach with an alternative defence of this laissez-faire intuition based on a significant and increasingly important environmental value: Respect for an Independent Nature. The paper articulates (...) and defends naturalness value and explores its implications for the laissez-faire intuition and for concern about wild-animal suffering. | : Le présent essai examine la tension entre la préoccupation pour la souffrance des animaux sauvages et celle concernant l’influence massive des humains sur la nature. Il examine l’éthique animale de Clare Palmer, notamment sa tentative d’atteindre un équilibre entre la politique de non-intervention dans la nature dite du « laissez-faire » et nos engagements envers les animaux. L’article propose une approche alternative à celle de Palmer qui, tout en défendant cette intuition du « laissez-faire », se fonde cette fois sur une valeur environnementale significative de plus en plus importante : le Respect pour une Nature Indépendante. Le texte articule et défend la valeur de naturalité et examine les implications de celle-ci pour l’intuition du « laissez-faire » ainsi que pour le souci envers la souffrance des animaux sauvages.

This book about the philosophy of science is the second out of four volumes by Richard Ned Lebow in this book series. It not only provides a useful overview of this broad topic, but also provides deeper insight into specific topics like the philosophy of science causation, epistemology and methods, and especially on counter factual analysis.

Such claims are part 0f a viewpoint according t0 which mental images represent in thc manner of pictures. It is very natural t0 think that such claims are confused or nonsensical.

This essay offers a reconsideration of the ethical vocabulary, social possibilities and religious worldview enabled by the German concept of Bildung, or human self-cultivation, a concept which was enthusiastically adopted by German Jews in the late eighteenth century. By examining the creative use of the concept by German Jewish philosophers such as Moses Mendelssohn (1729?1786) and, later, in a very different political context, Ernst Cassirer (1874?1945), the article challenges a body of scholarship that interprets the German Jewish enthusiasm for Bildung (...) as an assimilationist capitulation by post-emancipation German Jews to the individualism and rationalism of the German Enlightenment. In contrast, I suggest that both Mendelssohn and Cassirer saw Bildung's emphasis on the vita activa as offering a vehicle for multifarious human engagement with the world that inspired not only a movement beyond reified conceptions of tradition, whether religious or secular, but forms of activism that could combine cosmopolitan sympathies with communal affiliation.

One of the most important issues concerning the foundations ofconscious perception centerson thequestion of whether perceptual consciousness is rich or sparse. The overflow argument uses a form of ‘iconic memory’ toarguethatperceptual consciousnessisricher (i.e.,has a higher capacity) than cognitive access: when observing a complex scene we are conscious of more than we can report or think about. Recently, the overflow argumenthas been challenged both empirically and conceptually. This paper reviews the controversy, arguing that proponents of sparse perception are committed to the (...) postulation of (i) a peculiar kind of generic conscious representation that has no independent rationale and (ii) an unmotivated form of unconscious representation that in some cases conflicts with what we know about unconscious representation.

Hugh of Saint Victor was an incredibly influential philosopher and theologian in 10th century France-his eloquence and writing earning him fame exceeding even that of St. Bernard. Yet despite his medieval celebrity, Hugh remains incredibly understudied in contemporary academica. Paul Rorem offers a basic introduction to Hugh's theology, through a comprehensive survey of his works. Drawing his evidence not only from Hugh's own descriptions of his work but from the earliest manuscript traditions of his writings, Rorem organizes and (...) presents his corpus within a tri-part framework, treating each of Hugh's major works in its appropriate place, and orienting the reader to its contents, as well as its location in Hugh's overarching program of theological pedagogy.

This book argues that there is a joint in nature between seeing and thinking, perception, and cognition. Perception is constitutively iconic, nonconceptual, and nonpropositional, whereas cognition does not have these properties constitutively. The book does not appeal to “intuitions,” as is common in philosophy, but to empirical evidence, including experiments in neuroscience and psychology. The book argues that cognition affects perception, i.e., that perception is cognitively penetrable, but that this does not impugn the joint in nature. A key part of (...) the argument is that we perceive not only low-level properties like colors, shapes, and textures but also high-level properties such as faces and causation. Along the way, the book explains the difference between perception and perceptual memory, the differences between format and content, and whether perception is probabilistic despite our lack of awareness of probabilistic properties. The book argues for perceptual categories that are not concepts, that perception need not be singular, that perceptual attribution and perceptual discrimination are equally fundamental, and that basic features of the mind known as “core cognition” are not a third category in between perception and cognition. The chapter on consciousness leverages these results to argue against some of the most widely accepted theories of consciousness. Although only one chapter is about consciousness, much of the rest of the book repurposes work on consciousness to isolate the scientific basis of perception. (shrink)

Argues for a failure of correspondence between perceptual representation and what it is like to perceive. If what it is like to perceive is grounded in perceptual representation, then, using considerations of veridical representation, we can show that inattentive peripheral perception is less representationally precise than attentive foveal perception. However, there is empirical evidence to the contrary. The conclusion is that perceptual representation cannot ground what it is like to perceive.

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (shrink)

In a recent paper I argued that agent causation theorists should be compatibilists. In this paper, I argue that compatibilists should be agent causation theorists. I consider six of the main problems facing compatibilism: (i) the powerful intuition that one can't be responsible for actions that were somehow determined before one was born; (ii) Peter van Inwagen's modal argument, involving the inference rule (β); (iii) the objection to compatibilism that is based on claiming that the ability to do otherwise is (...) a necessary condition for freedom; (iv) "manipulation arguments," involving cases in which an agent is manipulated by some powerful being into doing something that he or she would not normally do, but in such a way that the compatibilist's favorite conditions for a free action are satisfied; (v) the problem of constitutive luck; and (vi) the claim that it is not fair to blame someone for an action if that person was determined by forces outside of his or her control to perform that action. And in the case of each of these problems, I argue that the compatibilist has a much more plausible response to that problem if she endorses the theory of agent causation than she does otherwise.

qualia include the ways it feels to see, hear and smell, the way it feels to have a pain; more generally, what it's like to have mental states. Qualia are experiential properties of sensations, feelings, perceptions and, in my view, thoughts and desires as well. But, so defined, who could deny that qualia exist? Yet, the existence of qualia is controversial. Here is what is controversial: whether qualia, so defined, can be characterized in intentional, functional or purely cognitive terms. Opponents (...) of qualia think that the content of experience is intentional content (like the content of thought), or that experiences are functionally definable, or that to have a qualitative state is to have a state that is monitored in a certain way or accompanied by a thought to the effect that I have that state (seecontent functionalism; intentionality). If we include the idea that experiential properties are not intentional or functional or purely cognitive in the definition of ‘qualia’, then it is controversial whether there are qualia. (shrink)

Animal beauty provides a significant aesthetic reason for protecting nature. Worries about aesthetic discrimination and the ugliness of predation might make one think otherwise. Although it has been argued that aesthetic merit is a trivial and morally objectionable basis for action, beauty is an important value and a legitimate basis for differential treatment, especially in the case of animals. While the suffering and death of animals due to predation are important disvalues that must be recognized, predation’s tragic beauty has positive (...) aesthetic value that can be appropriately aesthetically appreciated.

My topic is the question 'Does time pass?'. Although much has been written in attempts to answer this question, not enough attention has been paid to the asking of the question itself. As a result, it has not been clear exactly what is at issue in this matter, and, consequently, it has not been clear just what are the different views available to one who wishes to give an answer to the question. I hope to ameliorate this situation. ;The aims (...) of my essay are: to state the issues involved in the controversy over temporal passage in a fruitful way; to formulate what I see as the leading candidates among the possible responses to those issues; and to consider the best arguments relevant to the choice among these alternative views. ;Roughly one-quarter of the essay is devoted to linguistic questions about time and tense. Another quarter is devoted to metaphysical matters involving the status of such putative properties as pastness, presentness and futurity. What emerge are not just two but, rather, five distinct views about whether or not time passes: one view, which I call the 4D view, to the effect that time does not pass, and four different views, which I call the 3D views, to the effect that time does pass. Each of these five views consists of a package of linguistic and metaphysical components. ;Once I have formulated these five different views, I present, for each of the five views, a formal language, with semantics, that would be appropriate for that view. Next, various arguments that have been suggested in the literature against the claim that time passes are considered as arguments against the 3D views; each such argument is found to be defective. Similarly, various arguments that have been suggested in the literature against the claim that time does not pass are considered as arguments against the 4D view; each of these arguments is also found to be defective. ;Finally, I explain why I prefer a certain one of the 3D views over its four rivals, and I consider some possible objections to that view.

Let’s begin with a simple example. Consider two quarks: one near the tip of your nose, the other near the center of Alpha Centauri. Here is a question about these two subatomic particles: Is there an object that has these two quarks as its parts and that has no other parts? According to one view of the matter (a view that is surprisingly endorsed by a great many contemporary philosophers), the answer to this question is Yes. But I think it (...) is fair to say that according to common sense, the answer to this question is really No, there is no object that has as its only two parts a quark near the tip of your nose and another quark near the center of Alpha Centauri.

I argue that time travel to the past is impossible, given a certain metaphysical theory, namely, The Dynamic Theory of Time. I first spell out my particular way of capturing the difference between The Dynamic Theory of Time and its rival, The Static Theory of Time. Next I offer four different arguments for the conclusion that The Dynamic Theory is inconsistent with the possibility of time travel to the past. Then I argue that, even if I am wrong about this, (...) it will still be true that The Dynamic Theory entails that you should not want to travel back to the past. Finally, I conclude by considering a puzzle that arises for those who believe that time travel to the past is metaphysically impossible: What exactly are we thinking about when we seem to be thinking about traveling back in time? For it certainly does not feel like we are thinking about something that is metaphysically impossible. (shrink)

Although many aspects of Bonaventure’s little classic De Reductione Artium ad Theologiam have been addressed in recent literature,1 the translation of the title remains problematic, not only from Latin into English but also from a Greek precedent into Latin. Calling it “On the Reduction of the Arts to Theology” always requires an explanation of the word “reduction.”2 How all the arts, indeed all of human learning, relate to theology and thus to God can hardly be considered a reduction in the (...) usual sense. “Leading back” is better, because it suggests the overall theological structure, but is still an incomplete translation, as revealed by the Greek background.
