The Internet has drastically changed how people interact, communicate, conduct business, seek jobs, find partners, and shop. Millions of people are using social networking sites to connect with others, and employers are using these sites as a source of background information on job applicants. Employers report making decisions not to hire people based on the information posted on social networking sites. Few employers have policies in place to govern when and how these online character checks should be used and how (...) to ensure that the information viewed is accurate. In this article, we explore how these inexpensive, informal online character checks are harmful to society. Guidance is provided to employers on when and how to use these sites in a socially responsible manner. (shrink)
When brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: the changes become extremely difficult to notice, even when they are large, presented repeatedly, and the observer expects them to occur (Rensink, O'Regan, & Clark, 1997). To determine the mechanisms behind this induced "change blindness", four experiments examine its dependence on initial preview and on the nature of the interruptions used. Results support the proposal that representations (...) at the early stages of visual processing are highly volatile, and that focused attention is needed to stabilize them sufficiently to support the perception of change.

Adams and Aizawa, in a series of recent and forthcoming papers ((2001), (In Press), (This Volume)) seek to refute, or perhaps merely to terminally embarrass, the friends of the extended mind. One such paper begins with the following illustration: "Question: Why did the pencil think that 2+2=4? Clark's Answer: Because it was coupled to the mathematician" Adams and Aizawa (this volume) ms p.1 "That" the authors continue "about sums up what is wrong with Clark's extended mind hypothesis". The (...) example of the pencil, they suggest, is just an especially egregious version of a fallacy said to pervade the literature on the extended mind. This fallacy, which they usefully dub the "coupling-constitution fallacy", is attributed , in varying degrees and manners, to Van Gelder and Port (1995), Clark and Chalmers (1998), Haugeland (1998), Dennett (2000), Clark (2001), Gibbs (2001), and Wilson (2004). The fallacy, of course, is to move from the causal coupling of some object or process to some cognitive agent, to the conclusion that the object or process is part of the cognitive agent , or part of the agent's cognitive processing (see e.g. Adams and Aizawa (This volume) ms p.2). Proponents of the extended mind and related theses, Adams and Aizawa repeatedly assert, are prone to this fallacy in part because they either ignore or fail to properly appreciate the importance of " the mark of the cognitive" viz the importance of an account of "what makes something a cognitive agent" (op cit ms p.3). The positive part of Adams and Aizawa's critique then emerges as a combination of the assertion that this "mark of the cognitive" involves the idea that "cognition is constituted by certain sorts of causal process that involve non-derived contents" (e.g. op cit ms p.3) and that these processes look to be characterized by psychological laws that turn out to apply to many internal goings-on but not currently (as a matter of contingent empirical fact) to any processes that take place in non-biological tools and artifacts. In what follows, I shall try to show why these arguments display nothing so much as mutual failures of communication: crossed wires concealing a couple of real, important, but much more subterranean, disagreements. In particular, I try to show why the negative considerations advanced by Adams and Aizawa fail to successfully undermine the argument for the extended mind, and why their more radical positive story, unless supplemented by implausible additional claims, fails to cast doubt on the claim that minds like ours can (without the need for any radically new techniques, technologies or interventions) extend into the world.

Austen Clark offers a general account of the forms of mental representation that we call "sensory." Drawing on the findings of current neuroscience, Clark defends the hypothesis that the various modalities of sensation share a generic form that he calls "feature-placing." Sensing proceeds by picking out place-times in or around the body of the sentient organism, and characterizing qualities (features) that appear at those place-times. The hypothesis casts light on many other troublesome phenomena, including the varieties of illusion, (...) the problem of projection, the notion of a visual field, and the existence of sense-data.

This essential guide to paradoxes takes the reader on a lively tour of puzzles that have taxed thinkers from Zeno to Galileo and Lewis Carroll to Bertrand Russell. Michael Clark uncovers an array of conundrums, such as Achilles and the Tortoise, Theseus' Ship, Hempel's Raven, and the Prisoners' Dilemma, taking in subjects as diverse as knowledge, ethics, science, art and politics. Clark discusses each paradox in non-technical terms, considering its significance and looking at likely solutions.
1. Clark’s book is a detailed study of the nature of sensory representation. It is highly informed by empirical results in the psychology of perception, and philosophically rich and significant. I admire the book and learned a great deal from reading it. As it covers a wide range of topics, and as I have no overarching critique to present, in this commentary I will briefly address three issues that come up in the book: Clark’s relational type-identity thesis for (...) sensory qualities, his theory that sensory representations involve proto-singular terms referring to spatio-temporal regions in the subject’s environment, and his interesting proposal concerning color to treat it as “difference coding”. Some of my remarks will be critical, but others will just explore some of the implications of his view. 2. Clark distinguishes “phenomenal properties” from “qualitative properties”, the former being appearance properties of things in the world (their colors, shapes, tastes, odors, etc.) and the latter being the properties of sensations by virtue of which they are sensations of their corresponding phenomenal properties. So when I see a red ball I am “directly” aware of the ball’s redness and roundness - it appears red and round to me. This awareness of the ball’s redness and roundness is accomplished, however, by my having a visual experience with certain qualitative properties; those that are of the sort one has when seeing something as red and round. It is these latter qualitative properties that are the subject of his relational type-identity thesis. Before addressing that thesis, however, I want to quickly note and respond to another point Clark makes concerning the qualitative properties of sensory states. He.. (shrink)
This second volume in the Limits and Renewals trilogy is an attempt to restate a traditional philosophy of mind, drawing on philosophical and poetical resources that are often neglected in modern and postmodern thought, and emphasizing the moral and political implications of differing philosophies of mind and value. Clark argues that without the traditional concept of the soul, we have little reason to believe that rational thought and individual autonomy are either possible or desirable. The particular topics covered include (...) the political context of identity claims, the possibility of knowledge and the dangers of curiosity, the fear of death, the philoprogenitive gene, and the mind-body problem.

What is war, and how should it be waged? Are there restraints on its conduct? What can philosophers contribute to the study of warfare? Arguing that the practice of war requires a sound philosophical understanding, Ian Clark writes a fascinating synthesis of the philosophy, history, political theory, and contemporary strategy of warfare. Examining the traditional doctrines of the "just" and the "limited" war with fresh insight, Clark also addresses the applicability of these ideas to the modern issues of (...) war crimes, choice of targets, guerrilla warfare, and nuclear strategy and deterrence.

Methods. We employed a "flicker" technique, in which an original and a modified image (each of duration 240 ms) continually alternated, with a blank field (duration 80 ms) between each display. Images were all of real-world scenes. One of three kinds of change (appearance/disappearance, color, or translation) was made to an object or region in each scene. Changes were large and easily seen under normal conditions. Subjects viewed the flicker display, and pressed a key when they noticed the change.
Is consciousness all in the head, or might the minimal physical substrate for some forms of conscious experience include the goings on in the (rest of the) body and the world? Such a view might be dubbed (by analogy with Clark and Chalmers’s ( 1998 ) claims concerning ‘the extended mind’) ‘the extended conscious mind’. In this article, I review a variety of arguments for the extended conscious mind, and find them flawed. Arguments for extended cognition, I conclude, do (...) not generalize to arguments for an extended conscious mind. (shrink)
In the last 10 years, several authors including Griffiths and Matthen have employed classificatory principles from biology to argue for a radical revision in the way that we individuate psychological traits. Arguing that the fundamental basis for classification of traits in biology is that of ‘homology’ (similarity due to common descent) rather than ‘analogy’, or ‘shared function’, and that psychological traits are a special case of biological traits, they maintain that psychological categories should be individuated primarily by relations of homology (...) rather than in terms of shared function. This poses a direct challenge to the dominant philosophical view of how to define psychological categories, viz., ‘functionalism’. Although the implications of this position extend to all psychological traits, the debate has centered around ‘emotion’ as an example of a psychological category ripe for reinterpretation within this new framework of classification. I address arguments by Griffiths that emotions should be divided into at least two distinct classes, basic emotions and higher cognitive emotions, and that these two classes require radically different theories to explain them. Griffiths argues that while basic emotions in humans are homologous to the corresponding states in other animals, higher cognitive emotions are dependent on mental capacities unique to humans, and are therefore not homologous to basic emotions. Using the example of shame, I argue that (a) many emotions that are commonly classified as being higher cognitive emotions actually correspond to certain basic emotions, and that (b) the “higher cognitive forms” of these emotions are best seen as being homologous to their basic forms.

Friedrich Nietzsche haunts the modern world. His elusive writings with their characteristic combination of trenchant analysis of the modern predicament and suggestive but ambiguous proposals for dealing with it have fascinated generations of artists, scholars, critics, philosophers, and ordinary readers. Maudemarie Clark's highly original study gives a lucid and penetrating analytical account of all the central topics of Nietzsche's epistemology and metaphysics, including his views on truth and language, his perspectivism, and his doctrines of the will-to-power and the eternal (...) recurrence. The Nietzsche who emerges from these pages is a subtle and sophisticated philosopher, whose highly articulated views are of continuing interest as contributions to a whole range of philosphical issues. This remarkable reading of Nietzsche will interest not only philosophers, but also readers in neighboring disciplines such as literature and intellectual history. (shrink)
Mind, it is increasingly fashionable to assert, is an intrinsically embodied and environmentally embedded phenomenon. But there is a potential tension between two strands of thought prominent in this recent literature. One of those strands depicts the body as special, and the fine details of a creature’s embodiment as a major constraint on the nature of its mind: a kind of new-wave body-centrism. The other depicts the body as just one element in a kind of equal-partners dance between brain, body (...) and world, with the nature of the mind fixed by the overall balance thus achieved: a kind of extended functionalism (now with an even broader canvas for multiple realizability than ever before). The present paper displays the tension, scouts the space of possible responses, and ends by attempting to specify what the body actually needs to be, given its complex role in these recent debates.

The key question in this three way debate is the role of the collectivity and of agency. Collins and Shrager debate whether cognitive psychology has, like the sociology of knowledge, always taken the mind to extend beyond the individual. They agree that irrespective of the history, socialization is key to understanding the mind and that this is compatible with Clark’s position; the novelty in Clark’s “extended mind” position appears to be the role of the material rather than the (...) role of other minds. Collins and Clark debate the relationship between self, agency, and the human collectivity. Collins argues that the Clark’s extended mind fails to stress the asymmetry of the relationship between the self and its material “scaffolding.” Clark accepts that there is asymmetry but that an asymmetrical ensemble is sufficient to explain the self. Collins says that we know too little about the material world to pursue such a model to the exclusion of other approaches including that both the collectivity and language have agency. The collectivity must be kept in mind!

There is a definite challenge in the air regarding the pivotal notion of internal representation. This challenge is explicit in, e.g., van Gelder, 1995; Beer, 1995; Thelen & Smith, 1994; Wheeler, 1994; and elsewhere. We think it is a challenge that can be met and that (importantly) can be met by arguing from within a general framework that accepts many of the basic premises of the work (in new robotics and in dynamical systems theory) that motivates such scepticism in the (...) first place. Our strategy will be as follows. We begin (Section 1) by offering an account (an example and something close to a definition) of what we shall term Minimal Robust Representationalism (MRR). Sections 2 & 3 address some likely worries and questions about this notion. We end (Section 4) by making explicit the conditions under which, on our account, a science (e.g., robot- ics) may claim to be addressing cognitive phenomena. (shrink)
What do linguistic symbols do for minds like ours, and how (if at all) can basic embodied, dynamical and situated approaches do justice to high-level human thought and reason? These two questions are best addressed together, since our answers to the first may inform the second. The key move in ‘scaling-up’ simple embodied cognitive science is, I argue, to take very seriously the potent role of human-built structures in transforming the spaces of human learning and reason. In particular, in this (...) paper I look at a range of cases involving what I dub ‘surrogate situations’. Here, we actively create restricted artificial environments that allow us to deploy basic perception-action- reason routines in the absence of their proper objects. Examples include the use of real-world models, diagrams and other concrete external symbols to support dense looping interactions with a variety of stable external structures that stand in for the absent states of affairs.

community reflecting on itself, uncovering its history, exploring its present predicament, and contemplating its future. [2] One aspect of this awakening is a process of philosophical reflection. As a philosophical approach, a social ecology investigates the ontological, epistemological, ethical and political dimensions of the relationship between the social and the ecological, and seeks the practical wisdom that results from such reflection. It seeks to give us, as beings situated in the course of real human and natural history, guidance in facing (...) specific challenges and opportunities. In doing so, it develops an analysis that is both holistic and dialectical, and a social practice that might best be described as an eco-communitarianism. (shrink)
We assemble here in this time and place to discuss the thesis that conscious attention can provide knowledge of reference of perceptual demonstratives. I shall focus my commentary on what this claim means, and on the main argument for it found in the first five chapters of Reference and Consciousness. The middle term of that argument is an account of what attention does: what its job or function is. There is much that is admirable in this account, and I am (...) confident that it will be the foundation, the launching-pad, for much future work on the subject. But in the end I will argue that Campbell’s picture makes the mechanisms of attention too smart: smarter than they are, smarter than they could be. If we come to a more realistic appraisal of the skills and capacities of our sub-personal minions, the “knowledge of reference” which they yield will have to be taken down a notch or two. (shrink)
This paper contrasts three different schemes of reference relevant to understanding systems of perceptual representation: a location-based system dubbed "feature-placing", a system of "visual indices" referring to things called "proto-objects", and the full sortal-based individuation allowed by a natural language. The first three sections summarize some of the key arguments (in Clark, 2000) to the effect that the early, parallel, and pre-attentive registration of sensory features itself constitutes a simple system of nonconceptual mental representation. In particular, feature integration--perceiving something (...) as being both F and G, where F and G are sensible properties registered in distinct parallel streams--requires a referential apparatus. Section V. reviews some grounds for thinking that at these earliest levels this apparatus is location-based: that it has a direct and nonconceptual means of picking out places. Feature-placing is contrasted with a somewhat more sophisticated system that can identify and track four or five "perceptual objects" or "proto-objects", independently of their location, for as long as they remain perceptible. Such a system is found in Zenon Pylyshyn's fascinating work on "visual indices", in Dana Ballard's notion of deictic codes, and in Kahneman, Treisman, and Wolfe's accounts of systems of evanescent representations they call "object files". Perceptual representation is a layered affair, and I argue that it probably includes both feature-placing and proto-objects. Finally, both nonconceptual systems are contrasted with the full-blooded individuation allowed in a natural language. (shrink)
Immortality has long preoccupied everyone from alchemists to science fiction writers. In this intriguing investigation, Stephen Clark contends that the genre of science fiction writing enables the investigation of philosophical questions about immortality without the constraints of academic philosophy. He shows how fantasy accounts of phenomena such as resurrection, outer body experience, reincarnation or life extending medicines can be related to philosophy in interesting ways. Reading Western myths such as that of vampire, he examines the ways fear and hopes (...) of immortality are an intrinsic part of Western culture and philosophy. As one of the first works to suggest the use of science fiction in the study of philosophy, Clark creates a ground for intellectual, philosophical and experimental inquiry. (shrink)
Fodor’s theory makes thinking prior to doing. It allows for an inactive agent or pure reflector, and for agents whose actions in various ways seem to float free of their own conceptual repertoires. We show that naturally evolved creatures are not like that. In the real world, thinking is always and everywhere about doing. The point of having a brain is to guide the actions of embodied beings in a complex material world. Some of those actions are, to be sure, (...) more recondite than others. But in every case the contents of thoughts still look to depend, in some non-unique but vitally important way, on the kinds of doings they support. (shrink)

Although the capacity to discriminate between different qualia is typically admitted to have a definition in terms of functional role, the qualia thereby related are thought to elude functional definition. In this paper I argue that these views are inconsistent. Given a functional model of discrimination, one can construct from it a definition of qualia. The problem is similar in many ways to Goodman's definition of qualia in terms of 'matching', and I argue that many of his findings survive reinterpretation (...) into a physicalistic basis which employs 'indiscriminability' as its primitive term. I show how one can identify the critical properties to which discrimination capacities are sensitive, and then identify their order. A problem arises concerning the different ways in which qualitatively distinct experiences can differ (hue, shape, and so on). Physicalist accounts have often been accused of relying in a circular fashion on some antecedent understanding of phenomenal properties in order to specify those differences. This account avoids such an accusation: ordering of critical properties is determined by the dimensionality of discriminations, and the latter is given by the structure of the discrimination pair lists. Once a topology of quality is constructed, qualia names can be defined by their relative location within the order. In the conclusion I argue that psychophysics employs physicalist techniques to define a topology of quality, and that it can provide what Thomas Nagel calls an "objective phenomenology.". (shrink)
The image of the presence of symbols in an inner code pervades recent debates in cognitive science. Classicists worship in the presence. Connectionists revel in the absence. However, the very ideas of code and symbol are ill understood. A major distorting factor in the debates concerns the role of processing in determining the presence or absence of a stuctured inner code. Drawing on work by David Kirsh and David Chambers , the present paper attempts to re-define such notions to begin (...) to reflect the inextrictability of code and presence. (shrink)
Selinger and Engstrom, A moratorium on cyborgs: Computation, cognition and commerce, 2008 (this issue) urge upon us a moratorium on ‘cyborg discourse’. But the argument underestimates the richness and complexity of our ongoing communal explorations. It leans on a somewhat outdated version of the machine metaphor (exemplified perhaps by a frozen 1970’s Cyborg). The modern cyborg, informed by an evolving computational model of mind, can play a positive role in the critical discussions that Selinger and Engstrom seek.

An inquiry into the possibility that life?after?death be understood as waking from a shared dream into the real world. Attempts to outlaw the possibility that ?really? we are, e.g., vat?brains are shown to lead to unwelcome, anti?realist conclusions about either the world or consciousness. The unsatisfactory nature of empirically observable (Humean) causal connections suggests that real causes may be found beyond the world of our present experience. Though such a story cannot now be proved to be true, we are entitled (...) to entertain it as a serious possibility. An attempt is made to say what life is like in the ?Real World?, whether this be a spatial world like our present one or not, and what moral it holds for our present life. I suggest (like Plato) that there are many levels of waking, and that our ?Real Self should not be identified simply with our present egos. (shrink)
A standard view in philosophy of mind is that qualia and phenomenal character require consciousness. This paper argues that various experimental and clinical phenomena can be better explained if we reject this assumption. States found in early visual processing can possess qualitative character even though they are not in any sense conscious mental states. This non-standard interpretation bears the burden of explaining what must be added to states that have qualitative character in order to yield states of sensory awareness or (...) sensory experience. I argue that the study of selective attention reveals resources that can be useful in that project. Two traditional objects are briefly considered. (shrink)
While applauding the bulk of the account on offer, we question one apparent implication viz, that every difference in sensorimotor contingencies corresponds to a difference in conscious visual experience.
Does the material basis of conscious experience extend beyond the boundaries of the brain and central nervous system? In Clark 2009 I reviewed a number of ‘enactivist’ arguments for such a view and found none of them compelling. Ward (2012) rejects my analysis on the grounds that the enactivist deploys an essentially world-involving concept of experience that transforms the argumentative landscape in a way that makes the enactivist conclusion inescapable. I present an alternative (prediction-and-generative-model-based) account that neatly accommodates all (...) the positive evidence that Ward cites on behalf of this enactivist conception, and that (I argue) makes richer and more satisfying contact with the full sweep of human experience.

As a worldview , naturalism depends on a set of cognitive commitments from which flow certain propositions about reality and human nature. These propositions in turn might have implications for how we live, for social policy, and for human flourishing. But the presuppositions, basis, and implications of naturalism are not uncontested, and indeed there’s considerable debate about them among naturalists themselves.
When you suffer a pain are you suffering a sensation? An emotion? An aversion? Pain typically has all three components, and others too. There is indeed a distinct sensory system devoted to pain, with its own nociceptors and pathways. As a species of somesthesis, pain has a distinctive sensory organization and its own special sensory qualities. I think it is fair to call it a distinct sensory modality, devoted to nociceptive somesthetic discrimination. But the typical pain kicks off other processes (...) too. For one it can grab your attention in a distinctive way, alerting you to its presence and sometimes obliging you to focus attention on the damaged member. Intense pain can eliminate your ability to think about anything else. Pain typically has direct and immediate motivational consequences: one wants it to stop, has an incentive to do whatever one can to reduce it, and is gratified by its termination. As these desires and motives collide with neural reality, emotional components of mental anguish, anxiety, and dread arise. The suffering involved in suffering from pain has multiple strands: it is not just the painfulness of the sensation, or the frustration of the desire that it end, but also the anguish over the possibility that it will never end, and the impossibility, if the pain is sufficiently intense, of focusing one’s attention on anything else.

Marinov''s critique I argue, is vitiated by its failure to recognize the distinctive role of superposition within the distributed connectionist paradigm. The use of so-called subsymbolic distributed encodings alone is not, I agree, enough to justify treating distributed connectionism as a distinctive approach. It has always been clear that microfeatural decomposition is both possible and actual within the confines of recognizably classical approaches. When such approaches also involve statistically-driven learning algorithms — as in the case of ID3 — the fundamental (...) differences become even harder to spot. To see them, it is necessary to consider not just the nature of an acquired input-output function but the nature of the representational scheme underlying it. Differences between such schemes make themselves best felt outside the domain of immediate problem solving. It is in the more extended contexts of performance DURING learning and cognitive change as a result of SUBSEQUENT training on new tasks (or simultaneous training on several tasks) that the effects of superpositional storage techniques come to the fore. I conclude that subsymbols, distribution and statistically driven learning alone are indeed not of the essence. But connectionism is not just about subsymbols and distribution. It is about the generation of whole subsymbol SYSTEMS in which multiple distributed representations are created and superposed. (shrink)
Mackie doubted anything objective could have the motivational properties of a value. In thinking we are morally required to act in a certain way, he said, we attribute objective value to the action. Since nothing has objective value, these moral judgments are all false. As to whether Mackie proved his error theory, opinions vary. But there is broad agreement on one issue. A litany of examples, ranging from amoralism to depression to downright evil, has everyone convinced that Mackie vastly overstated (...) the motivational implications of moral judgment. Mackie did go overboard. But did he have to? I think not. Even on the most modest motivational assumptions, Mackie can make objective value look queer and morality look like a sham. I begin with a sketch. (shrink)
This essay gives necessary and sufficient conditions for recovering expected utility from choice behavior in several popular models of uncertainty. In particular, these techniques handle a finite state model; a model for which the choice space consists of probability densities and the expected utility representation requires bounded, measurable utility; and a model for which the choice space consists of Borel probability measures and the expected utility representation requires bounded, continuous utility. The key result is the identification of the continuity condition (...) necessary for the revelation of linear utility. (shrink)

This stimulating and wide-ranging book mounts a profound enquiry into some of the most pressing questions of our age, by examining the relationship between biological science and Christianity. The history of biological discovery is explored from the point of view of a leading philosopher and ethicist. What effect should modern biological theory and practice have on Christian understanding of ethics? How much of that theory and practice should Christians endorse? Can Christians, for example, agree that biological changes are not governed (...) by transcendent values, or that there are no clear or essential boundaries between species? To what extent can 'Nature' set our standards? Professor Clark takes a reasoned look at biological theory since Darwin and argues that an orthodox Christian philosophy is better able to accommodate the truth of such theory than is the sort of progressive, meliorist interpretation of Christian doctrine which is usually offered as the properly 'modern' option.

Social justice is a key concept in current education policy and practice. It is, however, a problematic one in its application to schooling. This paper begins with a critique of the account of social justice offered by Gewirtz followed by an alternative philosophical notion based on the perfect world argument and the just society where equality is to the fore. This leads on to an exploration of what it is to be an educated citizen, consideration of the just school and (...) discussion of the place of the school as an instrument for attaining social justice. The conclusion draws attention to the importance of the policy web as a way of developing coherent and unified policy designed to achieve social justice for all. (shrink)

This is an enormously impressive achievement, and we hope that the comments that follow will (...) be. (shrink)

Some recent cognitive-scientific research suggests that a considerable amount of intelligent action is generated not by the systematic activity of internal representations, but by complex interactions involving neural, bodily, and environmental factors. Following an analysis of this threat to representational explanation, we pursue an analogy between the role of genes in the production of biological form and the role of neural states in the production of behaviour, in order to develop a notion of genic representation. In both cases an appeal (...) to normal ecological context is used to balance multi-factoral, interactive causal determination against the intuition that certain aspects of the causal nexus play a special role in promoting adaptive success. Certain worries abut this vision help us to get a better grip on the concept of genic representation itself. We end with a puzzle concerning the relation between cognition and representation.

Like those famous nations divided by a single tongue, my paper (this volume) and Professor P.M. Churchland's deep and engaging reply offer different spins on a common heritage. The common heritage is, of course, a connectionist vision of the inner neural economy- a vision which depicts that economy in terms of supra-sentential state spaces, vector-to-vector transformations, and the kinds of skillful pattern-recognition routine we share with the bulk of terrestrial intelligent life-forms. That which divides us is, as ever, much harder (...) to isolate and name. Clearly, it has something to do with the role of moral talk and exchange, and something to do with the conception of morality itself (and, correlatively, with the conception of moral progress). Most of this Reply will be devoted to clarifying the nature of the disputed territory. First, though (as a prophylactic against misunderstanding) I shall rehearse some points of agreement concerning moral talk and progress. (shrink)
This volume brings historians of science and social historians together to consider the role of "little tools"--such as tables, reports, questionnaires, dossiers, index cards--in establishing academic and bureaucratic claims to authority and objectivity. From at least the eighteenth century onward, our science and society have been planned, surveyed, examined, and judged according to particular techniques of collecting and storing knowledge. Recently, the seemingly self-evident nature of these mundane epistemic and administrative tools, as well as the prose in which they are (...) cast, has demanded historical examination. The essays gathered here, arranged in chronological order by subject from the late seventeenth to the late twentieth century, involve close readings of primary texts and analyses of academic and bureaucratic practices as parts of material culture. The first few essays, on the early modern period, largely point to the existence of a "juridico-theological" framework for establishing authority. Later essays demonstrate the eclipse of the role of authority per se in the modern period and the emergence of the notion of "objectivity." Most of the essays here concern the German cultural space as among the best exemplars of the academic and bureaucratic practices described above. The introduction to the volume, however, is framed at a general level the closing essays also extend the analyses beyond Germany to broader considerations on authority and objectivity in historical practice. The volume will interest scholars of European history and German studies as well as historians of science. Peter Becker is Professor of Central European History, European University Institute. William Clark is Lecturer in History and Philosophy of Science, Cambridge University. (shrink)

The necessity of incorporating societal and environmental concerns into publicly funded agricultural initiatives in research, extension, and practice is increasingly evident. Agriculturalists are urged to acknowledge and respond to societal concerns before an insensitive and largely ill-informed urban majority assumes a dominant posture in agricultural policy. In recent history, the availability of unrealistically cheap energy encouraged the evolution of a form of commercial agriculture unfettered by sound ecological principles. At present, external, resource-intensive intervention of increasing magnitude is needed to compensate (...) for the apparent ecological instability generated by practices such as intensive cereal management or conservation tillage practices. Polarization of the enterprises of plant and animal agriculture to enable centralized, concentrate-intensive, confinement feeding has disrupted the natural cycling of nutrients and carbon in the soil, encouraged the withdrawal of perennial forages from crop rotations, and invoked a widely ramifying network of agricultural and societal problems. Solutions to these problems must evolve from a holistic and far-reaching appraisal of causes, rather than from a piecemeal approach to individual symptoms. (shrink)
The Bishop of Questoriana has recently asked for a pontifical document ‘furnishing a doctrinal foundation of love and respect for life existing on the earth’. Mainstream moralists have urged, since the Axial Era, that it is human life that most demands love and respect. We realize and perfect our own humanity by recognizing humanity in every other, of whatever creed or race. Realizing that biological species are not natural kinds, more recent moralists have hoped to found moral decency either on (...) a respect for ‘rationality’ which excludes many of our conspecifics, or on simple loyalty to our immediate kin. Neither option is without its costs, and Catholic moralists in particular have often been suspicious of a morality that seems to lead to contempt for ordinary human life. Neither advocacy of ‘animal rights’ nor utilitarian calculation of animal pains and pleasures sit well with a traditional Catholic morality. Conversely, many of those who defend traditional practices such as hunting, farming or goading animals to fight, themselves suppose that ‘human’ and ‘animals’ may sometimes inhabit the same moral universe, that there are virtues that both may display in ‘noble action’. Developing this thought, it is possible to locate decency elsewhere than in an over-intellectual respect for ‘reason’. Decent treatment of animals (as of others) is that form of life which lets us live together ‘humanely’, in appreciation of the actual beings they are. Virtue, as Aristotle argued, lies less in acting nobly than in appreciating nobility. Those who claim to appreciate such nobility in beasts must learn to live humanely. (shrink)
Confusing modern poetry with philosophy is a common fault of literary criticism. Yet, the work of some poets can benefit critically from philosophical interpretations. Wallace Stevens is a poet who manifested an abiding interest in philosophy. His poems consistently display, in both their syntax and modulation of thought, philosophical parallels. Stevens’ dominant mode of thought is phenomenological. This can be shown by analyzing parallels between phenomenological methodology and Stevens’ poetry. Particularly three poems---“Thirteen Ways of Looking at a Blackbird” (1917), “The (...) Snow Man” (1921), and “The Latest Freed Man” (1938)---embody, respectively, the poem as doing phenomenology, the poem as a description of the phenomenological mind, and the poem as a portrait of the phenomenologist.

This book is an ambitious and challenging restatement of traditional political philosophy. The first of a three-volume series, Limits and Renewals, the book is concerned with the nature of political society, particularly with the errors and faulty arguments that have been used to support a "liberal modernist" view of the state and our political system. Clark argues that political modernism, which is determinedly secular and untraditional, has been a destructive influence on religion and our understanding of community living. In (...) order to secure a decent social order, he contends, we must rediscover our allegiance to a sacred order that is represented by, for example, family loyalties, a respect for tradition, and attention to the wider interests of the global and historical community.

The church’s mission to the world in the new millennium will require a careful balance of global vision and local sensitivity. Karl Rahner’s ecclesiology supplies useful tools for this balance, in that it moves toward an appreciation of the inherent authority and dignity of the local church community, understood as an interpersonal network within the broader church. Rahner’s focus on the church as sacrament provides the key consideration: that the church necessarily accomplishes its mission in the midst of concrete historical (...) contexts. Rahner also provides a way of understanding the presence of the whole church embodied in the local community, particularly as it gathers for Eucharist. This sharing in the essence of the church also manifests itself in the local community’s roles in nurturing and responding to official authority. Rahner’s trust in the work of the Spirit for the maintenance of unity allows him to revel in the church’s diversity. The local community shows most clearly the aspect of church as pilgrim in the world, which Rahner underscores. Because the local community embodies the universal church in a particular location, the study of the community and its contexts is essential for understanding the reality and the mission of the church in the world.

High-spin states in the odd-odd N = Z nucleus Co-54 have been investigated by the fusion-evaporation reaction Si-28(S-32,1 alpha 1p1n)Co-54. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1 pi neutron detector array. A significantly extended excitation scheme of Co-54 is presented, which includes a candidate for the isospin T = 1, 6(+) state of the 1f(7/2)(-2) multiplet. The results are compared to large-scale shell-model (...) calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations. (shrink)

In this book, Stephen R.L. Clark defends the primary faith of humankind, that there is a real world which is more than a shadow of our desires and fancies, and which can be discovered through right reason. Focusing on the way in which we can "turn aside" to the Truth from the normal delusions of self-concern, Clark offers a properly worked, Platonic metaphysics as the key to identifying that reality. This book is the final volume of Limits and (...) Renewals, a trilogy based on the author's Stanton lectures, delivered at Cambridge between 1986 and 1989, and his Wilde lectures, delivered at Oxford in 1990. (shrink)
Mindware: An Introduction to the Philosophy of Cognitive Science invites readers to join in up-to-the-minute conceptual discussions of the fundamental issues, problems, and opportunities in cognitive science. Written by one of the most renowned scholars in the field, this vivid and engaging introductory text relates the story of the search for a cognitive scientific understanding of mind. This search is presented as a no-holds-barred journey from early work in artificial intelligence, through connectionist (artificial neural network) counter-visions, and on to neuroscience, (...) artificial life, dynamics, and robotics. The journey ends with some wide-ranging and provocative speculation about the complex coadaptive dance between mind, culture, and technology. Each chapter opens with a brief sketch of a major research tradition or perspective, followed by short yet substantial critical discussions dealing with key topics and problems. Ranging across both standard philosophical territory and the landscape of cutting-edge cognitive science, Clark highlights challenging issues in an effort to engage readers in active debate. Topics covered include mental causation; machine intelligence; the nature and status of folk psychology; the hardware/software distinction; emergence; relations between life and mind; the nature of perception, cognition, and action; and the continuity (or otherwise) of high-level human intelligence with other forms of adaptive response. Numerous illustrations, text boxes, and extensive suggestions for further reading enhance the text's utility. Helpful appendices provide background information on dualism, behaviorism, identity theory, consciousness, and more. An exceptional text for introductory and more advanced courses in cognitive science and the philosophy of mind, Mindware is also essential reading for anyone interested in these fascinating and ever-changing fields.

We give a detailed account of the Algebraically Closed and Existentially Closed members of the second Lee class B 2 of distributive p-algebras, culminating in an explicit construction of the countable homogeneous universal model of B 2. The axioms of Schmid [7], [8] for the AC and EC members of B 2 are reduced to what we prove to be an irredundant set of axioms. The central tools used in this study are the strong duality of Clark and Davey (...) [3] for B 2 and the method of Clark [2] for constructing AC and EC algebras using a strong duality. Applied to B 2, this method transfers the entire discussion into an equivalent dual category X 2 of Boolean spaces which carry a pair of tightly interacting orderings. The doubly ordered spaces of X 2 prove to be much more readily constructed and analyzed than the corresponding algebras in B 2. (shrink)
THE AUTHOR ARGUES THAT THE ASSERTION THAT EXPERIENCE DENIES THE REALITY OF THE SUPERNATURAL WORLD IS ERRONEOUS. RATHER, CLARK INSISTS THAT THE BIBLICAL REPORT OF CREATION AS REPORTED IN GENESIS IS PROBABLY A MORE RELIABLE SCIENTIFIC ACCOUNT. THE "BEST GENERAL PHILOSOPHY," THE AUTHOR ARGUES, "IS THE REVELATIONAL PHILOSOPHY OF CHRISTIAN THEISM." (BP).
This is the first of two volumes of essays in commemoration of Alan Turing, whose pioneering work in the theory of artificial intelligence and computer science continues to be widely discussed today. A group of prominent academics from a wide range of disciplines focus on three questions famously raised by Turing: What, if any, are the limits on machine 'thinking'? Could a machine be genuinely intelligent? Might we ourselves be biological machines, whose thought consists essentially in nothing more than the (...) interaction of neurons according to strictly determined rules? The discussion of these fascinating issues is accessible to non-specialists and stimulating for all readers. -/- Also available in paperback is the companion volume: Connectionism, Concepts, and Folk Psychology, edited by Andy Clark and Peter Millican. While Volume 1 concentrates on Turing's main innovations in artificial intelligence, Volume 2 looks more broadly at his intellectual legacy in philosophy and cognitive science. (shrink)
Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

Medium- and high-spin states of Pr-134 were populated using the Cd-116(Na-23, 5n) reaction and studied with the GAMMASPHERE spectrometer. Several new bands have been found in this nucleus, one of them being linked to the previously observed chiral-candidate twin-band structure. The ground state of Pr-134 could be determined through establishing a level structure that connects the two previously known long-lived isomeric states. Unambiguous spin-parity assignments for the excited states could be performed based on the known 2(-) spin-parity of the ground (...) state combined with the present experimental data. Intrinsic single-particle configurations have been assigned to the newly observed bands on the basis of the measured B(M1)/B(E2) ratios, alignments, band-crossing frequencies, bandhead spins, the observed single-particle configurations in the neighboring nuclei, and taking into account the predictions of total Routhian surface and tilted-axis cranking calculations.
