As an explicit organizing metaphor, memory aid, and conceptual framework, the prefrontal cortex may be viewed as a five-member ‘Executive Committee,’ as the prefrontal-control extensions of five sub-and-posterior-cortical systems: the ‘Perceiver’ is the frontal extension of the ventral perceptual stream which represents the world and self in object coordinates; the ‘Verbalizer’ is the frontal extension of the language stream which represents the world and self in language coordinates; the ‘Motivator’ is the frontal cortical extension of a subcortical extended-amygdala stream which (...) represents the world and self in motivational/emotional coordinates; the ‘Attender’ is the frontal cortical extension of a subcortical extended-hippocampal stream which represents the world and self in spatiotemporal coordinates and directs attention to internal and external events; and the ‘Coordinator’ is the frontal extension of the dorsal perceptual stream which represents the world and self in body- and eye-coordinates and controls willed action and working memory. This tutorial review examines the interacting roles of these five systems in perception, working memory, attention, long - term memory, motor control, and thinking. (shrink)

Much of the current imaging literature either denies the existence of wakeful non-mental imagers, views non-imagers motivationally as 'repressors' or 'neurotic', or acknowledges them but does not fully incorporate them into their models. Neurobiologists testing for imaging loss seem to assume that visual recognition, describing objects, and free-hand drawing require the forming of conscious images. The intuition that 'the psyche never thinks without an image.... the reasoning mind thinks its ideas in the form of images' (Aristotle) has a long tradition (...) in philosophical psychology, from Aristotle through the British empiricists to the British-empiricist-inspired introspection paradigm of Titchener. The massive shift in early experimental psychology to the introspective-antagonistic paradigm of Watson's behaviourism, may have sprung from the contrary intuition that no one thinks in mental images. In both cases, people seemed to assume that what is in one's own mind is in everybody's mind. A third, mediating, intuition - that some people do not think with conscious mental imagery -- seems to be confirmed by empirical studies on many levels. From the early imagery interviews of Francis Galton through many modern surveys, including my own, a consistent diversity of self-reports on ones own mental imagery abilities suggests that some 2-5% of people are very poor- or non-visual- imagers who, yet, maintain normal visual recognition abilities. Comparable estimates have been made in auditory and other imagery modalities. (shrink)

Major strands of the history of scientific psychology proposed less mechanistic explanations of behavior than the “series of billiard ball reactions” that Ellis ascribes to them. I tease apart psychological systems based on hedonism and those based on stimulus-response mechanisms-and then tease apart basic hedonism and drive-reduction hedonism, to layout psychological and neuroscientific foundations for the active, dynamic, cognitive, emotive, and "spiritual" dynamics of human nature which Ellis calls us to affirm. I trace these distinctions through the drive-reduction psychoanalysis of (...) Freud, the drive-reduction behaviorism of Hull, and the non-drive-reductive hedonistic system of Skinner. Then I trace the recent neuroscience of reward and punishment circuits and putative narcissistic and altruistic circuits, to conclude that Behaviorism and Neuroscience support broad hedonistic but major non-drive-reduction motivational systems. I affirm Ellis’ contention that emotions are basically “active”, although with some caveats and questions. (shrink)

To define 'consciousness' is to describe its uses and deter-mine its boundaries, essential nature, and mechanisms. I distinguish between 'normal waking consciousness'; altered forms of waking consciousness underlying trance, absorption, hypnosis, dissociation, meditative states, drug states, and out of body experiences; and REM/dreaming and slow-wave/deep sleep - examining them by the basic characteristics and mechanisms of normal waking conscious-ness: cortical arousal, qualitative experiences, first-person subjectiv-ity, intentionality, knowing objects and self, interaction with external and inner world, united field, and reflective consciousness.

Conference Report for Toward a Science of Consciousness Tucson Conference, April 4- 8, 2006.

This was my first 'Tucson-overseas' conference, and I will begin by briefly comparing this series with the (to me) more familiar ASSC and Tucson conferences -- several of which I have reviewed for JCS.

Conference Report for Toward a Science of Consciousness Tucson Conference, April 4- 8, 2006.

I have suggested that the prefrontal cortex constitutes an ?executive committee? with five streams coming from posterior cortex and subcortical areas to five pre-frontal executive regions, each of which chairs at least one on-going ?sub-committee? and vies with the other executives for taking over central control of conscious attention and willed action. It is through the dynamic interaction of this executive committee that unified conscious experiences and a sense of continuous self-identity are created. There is growing evidence that the amygdala-orbitofrontal (...) brain circuit, in particular, is crucial to impulse control, ?knowledge of good and evil,? personality, personhood, and even ?how X-me made Y-me do something.? There are striking examples of the ways that orbitofrontal and anterior cingulate ?committee members? can stage an insurrection against the dorsolateral prefrontal cortex executive chair. (shrink)

In the town where Elvis' occurrent consciousness status is periodically asserted, the Association for the Scientific Study of Consciousness held another great conference. The King of rockabilly did not show, but many stars of consciousness- and related-gigs did, such as Ned Block, Walter Freeman, Bernie Baars, Alva Noë, Dan Dennett, Christof Koch, Sue Savage-Rumbaugh, Peter Carruthers and Petra Stoerig. Even though this was my fifth ASSC conference I had never heard the famous Freeman nor the devilish Dennett before. There were (...) 21 plenary/ symposium speakers plus 10 workshops, 36 concurrent sessions and 20 posters over four packed days. Great stuff! (shrink)

A Review of ASSC-9 at Cal-Tech, June 24-27, 2005.

When the cognitive neuroscience of consciousness is finally written, it will likely have many of the elements documented in this fine book. My review is relatively detailed because, out of fourteen authors of the eight articles in this book, only four have previously appeared in the Journal of Consciousness Studies.

The International Union of Psychological Science ('Union') co-hosted, with the Chinese Psychological Society its 28th International Congress of Psychology ('Congress'). The first Congress was held with the World's Fair in Paris in 1889. In recent decades, they have been held every four years in different parts of the world. The Union has member organizations from 67 nations, representing one half million psychologists. Pretty scary stuff!

Early modern empiricists thought that the nature of perceptual experience is given by citing the object presented to the mind in that experience. Hallucination and illusion suggest that this requires untenable mind-dependent objects. Current orthodoxy replaces the appeal to direct objects with the claim that perceptual experience is characterized instead by its representational content. This paper argues that the move to content is problematic, and reclaims the early modern empiricist insight as perfectly consistent, even in cases of illusion, with the (...) realist contention that these direct objects of perception are the persisting mind-independent physical objects we all know and love. (shrink)

What is the role of conscious experience in the epistemology of perceptual knowledge: how should we characterise what is going on in seeing that o is F in order to illuminate the contribution of seeing o to their status as cases of knowing that o is F? My proposal is that seeing o involves conscious acquaintance with o itself, the concrete worldly source of the truth that o is F, in a way that may make it evident to the subject (...) that o is an instance of ‘x is F’ as she understands this, and hence evident that o is F. Seeing that o is F is thus a way of its being evident that o is F and is therefore a way of knowing that o is F. (shrink)

Several philosophers think there are important analogies between emotions and perceptual states. Furthermore, considerations about the rational assessibility of emotions have led philosophers—in some cases, the very same philosophers—to think that the content of emotions must be propositional content. If one finds it plausible that perceptual states have propositional contents, then there is no obvious tension between these views. However, this view of perception has recently been attacked by philosophers who hold that the content of perception is object‐like. I shall (...) argue for a view about the content of emotions and perceptual states which will enable us to hold both that emotional content is analogous to perceptual content and that both emotions and perceptual states can have propositional contents. This will involve arguing for a pluralist view of perceptual content, on which perceptual states can have both contents which are proposition‐like and contents which are object‐like. I shall also address two significant objections to the claim that emotions can have proposition‐like contents. Meeting one of these objections will involve taking on a further commitment: the pluralist account of perceptual content will have to be one on which the contents of perception can be non‐conceptual.

A timely new edition of the classic journalism guide, now featuring updated material on the importance of reporting in the age of media mistrust and fake news--and how journalists can use technology while also navigating its challenges. More than two decades ago, the Committee of Concerned Journalists gathered some of America's most influential newspeople to ask the question "What is journalism for?" Through exhaustive research, surveys, interviews, and public forums, they identified the essential elements that define journalism and its role (...) in our society. The result is one of the most important books on the media ever written, winner of the Goldsmith Book Prize from Harvard, the Society of Professional Journalists Award, and the Bart Richards Award from Penn State University. Updated with new material covering the ways journalists can deftly leverage technology to their advantage, especially given the shifting revenue architecture--with "clickbait" fading away and consumers paying a higher premium for quality reporting--this fourth edition of The Elements of Journalism is an essential read for journalists, students, and anybody hoping to stay informed in contentious times.

We do not yet have a sound ontology for intrinsic value. Albert Borgmann’s work on information technology and Daniel Dennett’s thoughts on evolutionary theory can provide the basis for an account of intrinsic value in terms of what it is, how it comes into existence, where it is found, and whether it can be quantified or compared. Borgmann’s information and realization relations are cornerstones forunderstanding value. According to Borgmann, things are valuable when they are meaningful and things become meaningful as (...) information and realizations. It is in these relations that intrinsic and extrinsic values find their common roots. Dennett’s musing on the relationship between DNA instructions, DNA readers, and phenotypes invites a commingling of information technology and evolutionary theory. His notion of design space provides a basis for the claim the biotic community has on intrinsic and extrinsic values. (shrink)

I take it for granted that sense experiential states provide reasons for empirical beliefs; indeed this claim forms the first premise of my central argument for (CC). 1 The subsequent stages of the argument are intended to establish that a person has such a reason for believing something about the way things are in the world around him only if he is in some mental state or other with a conceptual content: a conceptual state. Thus, given that sense experiential states (...) do provide reasons for empirical beliefs, they must have conceptual content. (shrink)

We perceive a world of mind-independent macroscopic material objects such as stones, tables, trees, and animals. Our experience is the joint upshot of the way these things are and our route through them, along with the various relevant circumstances of perception; and it depends on the normal operation of our perceptual systems. How should we characterise our perceptual experience so as to respect its basis and explain its role in grounding empirical thought and knowledge? I offered an answer to this (...) question in Perception and its objects. Here I aim to clarify some of my central arguments and to develop and defend the position further in the light of subsequent critical discussion. (shrink)

How do legal texts determine legal content? A standard answer to this question—sometimes called “the standard picture”—is that legal texts communicate something and what they communicate is identical to legal content. Mark Greenberg criticizes the standard picture and offers in its place his own “moral impact theory.” My goal here is to respond to Greenberg by showing how the standard picture better explains legal practice than the moral impact theory does. To that end, I first clarify certain aspects of the (...) moral impact theory. I then critique the theory, focusing on its inability to explain (i) why practitioners reason about legal content as they do and (ii) why they agree on legal content as often as they do. Finally, I refine the standard picture and demonstrate how it explains what the moral impact theory cannot. (shrink)

The question how to account for illusion has had a prominent role in shaping theories of perception throughout the history of philosophy. Prevailing philosophical wisdom today has it that phenomena of illusion force us to choose between the following two options. First, reject altogether the early modern empiricist idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience. Instead we must characterize perceptual experience entirely in terms of its (...) representational content. Second, retain the early modern idea that the core subjective character of experience is simply constituted by the identity of its direct objects, but admit that these must be mind-dependent entities, distinct from the mind-independent physical objects we all know and love. I argue here that the early modern empiricists had an indispensable insight. The idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience is more fundamental than any appeal to perceptual content, and can account for illusion, and indeed hallucination, without resorting to the problematic postulation of any such mind-dependent objects.

In The Varieties of Reference (1982), Gareth Evans claims that considerations having to do with certain basic ways we have of gaining knowledge of our own physical states and properties provide "the most powerful antidote to a Cartesian conception of the self" (220). In this chapter, I start with a discussion and evaluation of Evans' own argument, which is, I think, in the end unconvincing. Then I raise the possibility of a more direct application of similar considerations in defence of (...) common sense anti-Cartesianism. Progress in this direction depends upon a far more psychologically informed understanding of normal and abnormal bodily awareness than is generally found in philosophical discussions of these issues. In the context of my attempt at some such understanding, I go on to assess the potential of this more direct line of argument. (shrink)

Bill Brewer presents an original view of the role of conscious experience in the acquisition of empirical knowledge. He argues that perceptual experiences must provide reasons for empirical beliefs if there are to be any determinate beliefs at all about particular objects in the world. This fresh approach to epistemology turns away from the search for necessary and sufficient conditions for knowledge and works instead from a theory of understanding in a particular area.

In this paper I discuss a number of different relationships between two kinds of obligation: those which have individuals as their subject, and those which have groups of individuals as their subject. I use the name collective obligations to refer to obligations of the second sort. I argue that there are collective obligations, in this sense; that such obligations can give rise to and explain obligations which fall on individuals; that because of these facts collective obligations are not simply reducible (...) to individual obligations; and that collective obligations supervene on individual obligations, without being reducible to them. The sort of supervenience I have in mind here is what is sometimes called ‘global supervenience’. In other words, there cannot be two worlds which differ in respect of the collective obligations which exist in them without also differing in respect of the individual obligations which exist in them.

Traditional ecocentric ethics relies on an ecology that emphasizes the stability and integrity of ecosystems. Numerous ecologists now focus on natural systems that are less clearly characterized by these properties. We use the elimination and restoration of wolves in Yellowstone to illustrate troubles for traditional ecocentric ethics caused by ecological models emphasizing instability in natural systems. We identify several other problems for a stability-integrity based ecocentrism as well. We show how an ecocentric ethic can avoid these difficulties by emphasizing the (...) value of the wildness of natural systems and we defend wildness value from a rising tide of criticisms. (shrink)

Psychiatry is unique in medicine in being on the border between science and the humanities. Science provides insight into the 'causes' of a problem, enabling us to formulate an 'explanation', while the humanities provide insight into its 'meanings' and helps with our 'understanding'. The new interdisciplinary field of 'philosophy of psychiatry' has developed to explore the range of issues relevant to this border country. The Oxford Textbook of Philosophy and Psychiatry is a unique textbook which provides a detailed introduction to (...) the field, a framework for study and skill development, and an overview of current research. It focuses on case studies in 5 key topic areas. Each case study is supported by selected readings from both philosophy and mental health, thinking skills exercises, self-test questions, key learning points and detailed guides to further reading.

Over the past ten years, we have worked in a collaboration between educators and computer scientists at the University of Illinois to imagine futures for education in the context of what is loosely called “artificial intelligence.” Unhappy with the first generation of digital learning environments, our agenda has been to design alternatives and research their implementation. Our starting point has been to ask, what is the nature of machine intelligence, and what are its limits and potentials in education? This paper (...) offers some tentative answers, first conceptually, and then practically in an overview of the results of a number of experimental implementations documented in greater detail elsewhere. Our key finding is that artificial intelligence—in the context of the practices of electronic computing developing over the past three quarters of a century—will never in any sense “take over” the role of teacher, because how it works and what it does are so profoundly different from human intelligence. However, within the limits that we describe in this paper, it offers the potential to transform education in ways that—counterintuitively perhaps—make education more human, not less. (shrink)

Physical objects are such things as stones, tables, trees, people and other animals: the persisting macroscopic constituents of the world we live in. therefore expresses a commonsense commitment to physical realism: the persisting macroscopic constituents of the world we live in exist, and are as they are, quite independently of anyone.

From time to time we explain what people do by referring to their habits. We explain somebody’s putting the kettle on in the morning as done through “force of habit”. We explain somebody’s missing a turning by saying that she carried straight on “out of habit”. And we explain somebody’s biting her nails as a manifestation of “a bad habit”. These are all examples of what will be referred to here as habit explanations. Roughly speaking, they explain by referring to (...) a pattern of a particular kind of behaviour which is regularly performed in characteristic circumstances, and has become automatic for that agent due to this repetition.

Legal theorists tend to focus on disagreement over the law, and yet a theory of law should also explain why lawyers and judges agree on the law as often as they do. To that end, this article first pins down a precise sense in which there can be pervasive agreement on the law. It then argues that such agreement obtains in the United States and likely in many other jurisdictions as well. Finally, it contends that Hartian Positivism offers a straightforward (...) explanation of this phenomenon and, indeed, a better explanation than rival theories, like Ronald Dworkin’s Law as Integrity or Scott Shapiro’s Planning Theory. Given the ubiquity of legal agreement, Hartian Positivism’s explanatory superiority in this regard is a strong, albeit still not dispositive, consideration in its favour. The broader lesson is that theories of law should give greater priority to explaining legal agreement than many theories now do. (shrink)

Many authors hold that collectives, as well as individuals can be the subjects of obligations. Typically these authors have focussed on the obligations of highly structured groups, and of small, informal groups. One might wonder, however, whether there could also be collective obligations which fall on everyone – what I shall call ' global collective obligations '. One reason for thinking that this is not possible has to do with considerations about agency : it seems as though an entity can (...) only be the subject of obligations if it is an agent. In this paper, I try to show that the argument from agency is not a good reason for being sceptical about the existence of global collective obligations : it derives whatever plausibility it has from the idea that claims about obligation need to be addressable to some agent. My suggestion is that we should accept this principle about the addressability of obligations, but deny that the addressee of an obligation need be the subject of that obligation. The collective obligations of unstructured collections of individuals, including global collective obligations, meet the addressability requirement insofar as they require something of the individuals who make up the collective.
