Light and Kennison found that bias effects in the forced-choice perceptual identification of words occurred only in a subset of participants, those who claimed on a strategy questionnaire to be deliberately guessing words they had studied previously. McKoon and Ratcliff raised a number of objections to the proposal that bias effects are due to guessing strategies, citing difficulties in our statistical treatment of data, our use of subjective reports to classify participants, and our approach to the general problem of (...) separating implicit from explicit influences on performance. This article responds to these objections. (shrink)

In the typical single-stimulus perceptual identification task, accuracy is improved by prior study of test words, a repetition priming benefit. There is also a cost, inasmuch as previously studied words are likely to be produced as responses if the test word is orthographically similar but not identical to a studied word. In two-alternative forced-choice perceptual identification, a test word is flashed and followed by two alternatives, one of which is the correct response. When the two alternatives are orthographically similar, test (...) words identical to previously studied items are identified more accurately than new words but tests words orthographically similar to studied words are identified less accurately than new words . Ratcliff and McKoon argue that these are bias effects that arise in the decision stage of word identification. We report five experiments that examined the alternative hypothesis that these bias effects arise from postperceptual guessing strategies. In single-stimulus perceptual identification, repetition priming benefits were equally great for young and older adults who claimed to use deliberate guessing strategies and those who did not . In contrast, only groups of young and older people who claimed to deliberately guess studied words in a two-alternative forced-choice task showed reliable benefits and costs. Costs and benefits were abolished in the two-alternative forced-choice task when a very long study list was used, presumably because the increased retrieval burden made the use of deliberate guessing strategies less attractive . Under conditions similar to those of Experiment 3, repetition priming was observed in single-stimulus perceptual identification . These results are consistent with the view that costs and benefits in the forced-choice perceptual identification task arise from deliberate guessing strategies but that those in the single-stimulus task do not. The possibility that the observed relationship between strategy reports and priming effects reflects erroneous postexperimental assessments of strategies by participants is also considered. (shrink)

Children ranging from 3 to 5 years were introduced to two anthropomorphic robots that provided them with information about unfamiliar animals. Children treated the robots as interlocutors. They supplied information to the robots and retained what the robots told them. Children also treated the robots as informants from whom they could seek information. Consistent with studies of children's early sensitivity to an interlocutor's non-verbal signals, children were especially attentive and receptive to whichever robot displayed the greater non-verbal contingency. Such selective (...) information seeking is consistent with recent findings showing that although young children learn from others, they are selective with respect to the informants that they question or endorse.

The inaugural collection in an exciting new exchange between philosophers and geographers, this volume provides interdisciplinary approaches to the environment as space, place, and idea. Never before have philosophers and geographers approached each other's subjects in such a strong spirit of mutual understanding. The result is a concrete exploration of the human-nature relationship that embraces strong normative approaches to environmental problems.

Does the Buddhist doctrine of no-self imply, simply put, no-other? Does this doctrine necessarily come into conflict with an ethics premised on the alterity of the other? This article explores these questions by situating Emmanuel Levinas’s ethics in the context of contemporary Japanese philosophy. The work of twentieth-century Japanese philosopher Watsuji Tetsurō provides a starting point from which to consider the ethics of the self-other relation in light of the Buddhist notion of emptiness. The philosophy of thirteenth-century Zen Master (...) Dōgen casts doubt on Watsuji’s commitment to reciprocal self-other relationality, showing that the idea of self-emptiness disrupts any conventional understanding of reciprocity and promotes instead other-oriented compassion. Despite interesting similarities between the ethics of alterity and Buddhist compassion, a Buddhist-influenced understanding of alterity differs from Levinas on important points, by making possible the claim that all others—human, animal, plant, and mineral—are ethical others.

One of the key concepts in the Philosophy of Logic is the notion of inference. In this paper we expand the notion of logical inference and describe its role in a comprehensive theory of rationality. Some recent rationality theories either presuppose an unattainable logical capacity or they minimize the role of logic, in light of the vast amount of data on fallacious inferential performance. In this paper we defend the view that logical acuity, redefined to include heuristics, is a (...) necessary factor in rationality. We evaluate some presuppositions of algorithmic models and some normative and metatheoretical properties of heuristic models, and defend our model against possible objections. Our revised notion of logical inference functions as the nucleus of the notion of logical acuity which in turn is a necessary building block for a realistic model of rationality. This model emphasizes the logical role of inferential heuristics, cognitive constraints and contextuality, introduces concepts such as "obvious inference", "cautious deductive closure", and "familiarity", and develops the notions of cognitive economy and contextual limitations as tools for evaluating and predicting rational behavior.

Organelles transported along microtubules are normally moved to precise locations within cells. For example, synaptic vesiceles are transported to the neruronal synapse, the Golgi apparatus is generally found in a perinuclear location, and the membranes of the endoplasmic reticulum are actively extended to the cell periphery. The correct positioning of these organelles depends on microtubules and microtubule motors. Melanophores provide an extreme example of organized organelle transport. These cells are specialized to transport pigment granules, which are coordinately moved towards or (...) away from the cell center, and result in the cell appearing alternately light or dark. Melanophores have proved to be an ideal system for studying the mechanisms by which the cell controls the direction of its organelle transport. Pigment granule dispersion (the movement away from the cell center) requires protein phosphorylation, while pigment aggregation (the movement towards the cell center) requires protein dephosphorylation. The target of this phosphorylation and dephosphorylation event is a protein that interacts with the microtubule motor protein, kinesin. Thus, the direction of organelle transport along microtubules may be regulated by controlling the activity of a microtubule motor. (shrink)

The notion of rationality is crucial to Computer Science and Artificial Intelligence, Economics, Law, Philosophy, Psychology, Anthropology, etc. Most if not all of these disciplines presuppose the agent's capacity to infer in a logical manner. Theories about rationality tend toward two extremes: either they presuppose an unattainable logical capacity, or they tend to minimize the role of logic, in light of vast data on fallacious inferential performance. We analyze some presuppositions in the classical view of logic, and suggest empirical (...) and theoretical evidence for the place of inferential heuristics in a theory of rationality. We propose (1) to outline a new theory of rationality that includes the key notion of logical capacity as a necessary but realistic factor, (2) to expand the notion of inference to include non-deductive inference, specifically non-monotonic, and (3) to emphasize the logical role of inferential heuristics and constraints such as cognitive economy.

That photography is a supremely realistic medium may be the commonsense view, but—as Edward Steichen reminds us—it is by no means universal. Dissenters note how unlike reality a photograph is and how unlikely we are to confuse the one with the other. They point to “distortions” engendered by the photographic process and to the control which the photographer exercises over the finished product, the opportunities he enjoys for interpretation and falsification. Many emphasize the expressive nature of the medium, observing that (...) photographs are inevitably colored by the photographer’s personal interests, attitudes, and prejudices.1 Whether any of these various considerations really does collide with photography’s claim of extraordinary realism depends, of course, on how that claim is to be understood.Those who find photographs especially realistic sometimes think of photography as a further advance in a direction which many picture makers have taken during the last several centuries, as a continuation or culmination of the post-Renaissance quest for realism.2 There is some truth in this. Such earlier advances toward realism include the development of perspective and modeling techniques, the portrayal of ordinary and incidental details, attention to the effects of light, and so on. From its very beginning, photography mastered perspective. Subtleties of shading, gradations of brightness nearly impossible to achieve with the brush, became commonplace. Photographs include as a matter of course the most mundane details of the scenes they portray—stray chickens, facial warts, clutters of dirty dishes. Photographic images easily can seem to be what painters striving for realism have always been after. 2. See André Bazin, “The Ontology of the Photographic Image,” What is Cinema?, trans.

RÉSUMÉ Oublier Baudrillard? Pourquoi devrions-nous oublier un art qui, malgré sa remarquable sérénité et même sa nonchalance ostensible, s'acharne à nous dire quelque chose sur notre condition, un art qui ne craint ni d'investiguer, ni de raconter les terribles paradoxes de l'existence contemporaine et de la civilisation contemporaine, un art qui, aussi rare que cela puisse être, peut engendrer le paradoxe? ABSTRACT A respected commentator on contemporary French intellectual life, tells us that we should, perhaps, "forget Baudrillard" But why should (...) we forget such a subtle art as Baudrillard's? Why should we forget an art wich, for all its remarkable serenity and, even, ostensible nonchalance, remains impassioned to tell us something about our condition, an art fearing neither to investigate nor to narrate the terrible paradoxes of contemporary existence and contemporary civilization, indeed, an art wich, rare as this is, can bear paradox?

Suppose that the ultimate point of ethics is to make the world a better place. If it is, we must face the question: better in what respect? If the good is prior to the right — that is, if the rationale for all requirements of the right is that they serve to further the good in one way or another — then what is this good? Is there a single fundamental value capable of underlying and unifying all of our moral (...) categories? If so, how might it defeat the claims of rival candidates for this role? If not, is there instead a plurality of basic goods, each irreducible to any of the others? In that case, how do they fit together into a unified picture of the moral life? These are the questions I wish to address, in a necessarily limited way. To many the questions will seem hopelessly old-fashioned or misguided. Some deontologists will wish to reverse my ordering of the good and the right, holding that the right constrains acceptable conceptions of the good. For many contractarians, neither the good nor the right will seem normatively basic, since both are to be derived from a prior conception of rationality. Finally, some theorists will reject the classification of moral theories in terms of their basic normative categories, arguing that the whole foundationalist enterprise in ethics should be abandoned. In the face of these challenges to the priority of the good, and in light of the many current varieties of moral skepticism and relativism, I cannot provide a very convincing justification for raising the questions I intend to discuss.

In 1933, Ethel Thompson Overby became the first African American female principal in Richmond, Virginia. Her motto was ?It is better to light a candle than to curse the darkness? (Overby 1975, 1). Before becoming principal, Overby had been a teacher in the southern urban de jure segregated schools of the city. How did the racially segregated context impact her understanding of democracy as an African American woman? As a teacher, what educational practices did she subscribe to? What educational (...) theorizing underpinned her educational practices as a teacher and as a principal? Who was she? These were the questions that guided this research into the educational theorizing of Ethel T. Overby. This research seeks to further the understanding of the theorizing that underpinned the educational practices of African American female teachers and principals who taught and led in public urban de jure segregated southern schools (Charron 2009; Johnson 2000; May 2007; Walker 2009). This historical qualitative research provides knowledge about the educational theorizing of African American educators and how past practices can support the educational fortitude of African American students today. ?To be a teacher, you had to be a good citizen.??Ethel Thompson Overby (1975, 10).

Phase 1 healthy volunteer clinical trials—which financially compensate subjects in tests of drug toxicity levels and side effects—appear to place pressure on each joint of the moral framework justifying research. In this article, we review concerns about phase 1 trials as they have been framed in the bioethics literature, including undue inducement and coercion, unjust exploitation, and worries about compromised data validity. We then revisit these concerns in light of the lived experiences of serial participants who are income-dependent on (...) phase 1 trials. We show how participant experiences shift attention from discrete exchanges, behaviors, and events in the research enterprise to the ongoing and dynamic patterns of serial participation in which individual decision-making is embedded in collective social and economic conditions and shaped by institutional policies. We argue in particular for the ethical significance of structurally diminished voluntariness, routine powerlessness in setting the terms of exchange, and incentive structures that may promote pharmaceutical interests but encourage phase 1 healthy volunteers to skirt important rules.

This discussion revises and extends Jonny Anomaly's ‘public goods’ account of public health ethics in light of recent criticism from Richard Dees. Public goods are goods that are both non-rival and non-excludable. What is significant about such goods is that they are not always provided efficiently by the market. Indeed, the state can sometimes realize efficiency gains either by supplying such goods directly or by compelling private purchase. But public goods are not the only goods that the market may (...) fail to provide efficiently. This point to a way of broadening the public goods account of public health to accommodate Dees' counterexamples, without abandoning its distinctive appeal. On the market failures approach to public health ethics, the role of public health is to correct public health-related market failures of all kinds, so far as possible. The underlying moral commitment is to economic efficiency in the sense of Pareto: if we can re-allocate resources in the economy so as to raise the welfare of some without lowering the welfare of any other, we ought to do so.

Several types of inferences are employed in the diagnosis and prognosis of patients with brain injuries and disorders of consciousness. These inferences introduce unavoidable uncertainty, and can be evaluated in light of inductive risk: the epistemic and nonepistemic risks of being wrong. This article considers several ethically significant inductive risks generated by and interacting with inferences about patients with disorders of consciousness, and argues for prescriptive measures to manage and mitigate inductive risk in the context of disorders of consciousness.

Since its inception in 1968, the concept of whole-brain death has been contentious, and four decades on, controversy concerning the validity and coherence of whole-brain death continues unabated. Although whole-brain death is legally recognized and medically entrenched in the United States and elsewhere, there is reasonable disagreement among physicians, philosophers, and the public concerning whether brain death is really equivalent to death as it has been traditionally understood. A handful of states have acknowledged this plurality of viewpoints and enacted “conscience (...) clauses” that require “reasonable accommodation” of religious and moral objections to the determination of death by neurological criteria. This paper argues for the universal adoption of “reasonable accommodation” policies using the New Jersey statute as a model, in light of both the ongoing controversy and the recent case of Jahi McMath, a child whose family raised religious objections to a declaration of brain death. Public policies that accommodate reasonable, divergent viewpoints concerning death provide a practical and compassionate way to resolve those conflicts that are the most urgent, painful, and difficult to reconcile.

The right to die has for decades been recognised for persons in a vegetative state, but there remains controversy about ending life-sustaining medical treatment for persons in the minimally conscious state. The controversy is rooted in assumptions about the moral significance of consciousness, and the value of life for patients who are conscious and not terminally ill. This paper evaluates these assumptions in light of evidence that generates concerns about quality of life in the MCS. It is argued that (...) surrogates should be permitted to make decisions to withdraw life-sustaining medical treatment from patients in the MCS. (shrink)

AbstractThe sculptor Olafur Eliasson produces works together with his team that have two main goals: first, he intends to sensitize our daily perception of the world and our surroundings, and second, Eliasson’s works are not only works of art, but they also explore nature, the physical properties of light, of energy, of water, and other elements. With the famous project Little Suns, small plastic lamps with LED light bulbs and solar cells, he contributes to the amelioration of daily (...) life for those who do not have access to electricity even today. In other works he focuses on elementary phenomena such as the movement of elements in a vortex of water or air, on the properties of light, of mirrored light, or the fascinating world of kaleidoscopes. Some of these works are very popular and often include visitors such as the Weather Project in the Turbine Hall of the Tate Modern in London created in 2003. This work is said to have provoked spontaneous meetings, celebrations, and even episodes of civil protest. The work turned the museum into a kind of agora, the public square in Ancient Greek cities that was at the heart of daily life, of politics, of democratic practices. (shrink)

Moral reasoning traditionally distinguishes two types of evil: moral and natural. The standard view is that ME is the product of human agency and so includes phenomena such as war, torture and psychological cruelty; that NE is the product of nonhuman agency, and so includes natural disasters such as earthquakes, floods, disease and famine; and finally, that more complex cases are appropriately analysed as a combination of ME and NE. Recently, as a result of developments in autonomous agents in cyberspace, (...) a new class of interesting and important examples of hybrid evil has come to light. In this paper, it is called artificial evil and a case is made for considering it to complement ME and NE to produce a more adequate taxonomy. By isolating the features that have led to the appearance of AE, cyberspace is characterised as a self-contained environment that forms the essential component in any foundation of the emerging field of Computer Ethics. It is argued that this goes some way towards providing a methodological explanation of why cyberspace is central to so many of CE’s concerns; and it is shown how notions of good and evil can be formulated in cyberspace. Of considerable interest is how the propensity for an agent’s action to be morally good or evil can be determined even in the absence of biologically sentient participants and thus allows artificial agents not only to perpetrate evil but conversely to ‘receive’ or ‘suffer from’ it. The thesis defended is that the notion of entropy structure, which encapsulates human value judgement concerning cyberspace in a formal mathematical definition, is sufficient to achieve this purpose and, moreover, that the concept of AE can be determined formally, by mathematical methods. A consequence of this approach is that the debate on whether CE should be considered unique, and hence developed as a Macroethics, may be viewed, constructively, in an alternative manner. The case is made that whilst CE issues are not uncontroversially unique, they are sufficiently novel to render inadequate the approach of standard Macroethics such as Utilitarianism and Deontologism and hence to prompt the search for a robust ethical theory that can deal with them successfully. The name Information Ethics is proposed for that theory. It is argued that the uniqueness of IE is justified by its being non-biologically biased and patient-oriented: IE is an Environmental Macroethics based on the concept of data entity rather than life. It follows that the novelty of CE issues such as AE can be appreciated properly because IE provides a new perspective. In light of the discussion provided in this paper, it is concluded that Computer Ethics is worthy of independent study because it requires its own application-specific knowledge and is capable of supporting a methodological foundation, Information Ethics.

Jerry L. Walls, the author of books on hell and heaven, completes his tour of the afterlife with a philosophical and theological exploration and defense of purgatory, the traditional teaching that most Christians require a period of postmortem cleansing and purging of their sinful dispositions and imperfections before they will be fully made ready for heaven. He examines Protestant objections to the doctrine and shows that the doctrine of purgatory has been construed in different ways, some of which are fully (...) compatible with Protestant theology. In particular, while purgatory has often been understood as matter of punishment in order to make satisfaction for sins that have not been fully remitted, it can also be seen as the completion of the sanctification process, an account of the doctrine that is fully consistent with the Protestant doctrine of justification by faith. Purgatory assumes not only continuity of personal identity but also gradual moral and spiritual growth between death and resurrection. Different theories of personal identity are examined and assessed in light of these assumptions. Walls also shows that the traditional doctrine of purgatory is not understood as a second chance for salvation, but goes on to argue that it should be modified to allow for postmortem repentance. He concludes with an examination of C.S. Lewis's writings on purgatory, and suggests that Lewis can be a model for evangelicals and other Protestants to engage the doctrine of purgatory in a way that is true to their theology. (shrink)

The central role played by Darwin's analogy between selection under domestication and that under nature has been adequately appreciated, but I have indicated how important the domesticated organisms also were to other elements of Darwin's theory of evolution-his recognition of “the constant principle of change,” for instance, of the imperfection of adaptation, and of the extent of variation in nature. The further development of his theory and its presentation to the public likewise hinged on frequent reference to domesticates.We have seen (...) that Darwin's reliance on the analogy between domesticated varieties and wild species was a bold and original step, in light of contemporary views on the nature of domesticates. However, as Darwin undoubtedly foresaw, his reliance on the analogy created difficulties as well as solving problems, and these began with his Malthusian codiscoverer of the principle of natural selection, Alfred Russel Wallace. Wallace's paper “On the Tendency of Varieties to Depart Indefinitely from the Original Type,” presented to the Linnean Scoiety along with the first public unveiling of Darwin's theory, states: We see, then, that no inferences as to varieties in a state of nature can be deduced from the observation of those occurring among domestic animals. The two are so much opposed to each other in every circumstance of their existence, that what applies to the one is almost sure not to apply to the other. Domestic animals are abnormal, irregular, artificial; they are subject to varieties which never occur and never can occur in a state of nature.62Much has been made of the similarity of views of Darwin and Wallace, but this quotation surely reveals how utterly different their views were on what to Darwin was an important matter. Several critics of the Origin saw Darwin's reliance on the domesticates as his Achilles heel. As Young has pointed out, Samuel Wilberforce included the following passage in his attack on the Origin: Nor must we pass over unnoticed the transference of the argument from the domesticated to the untamed animals. Assuming that man as the selector can do much in a limited time, Mr. Darwin argues that Nature, a more powerful, a more continuous power, working over vastly extended ranges of time, can do more. But why should Nature, so uniform and persistent in all her operations, tend in this instance to change? Why should she become a selector of varieties?63Another critic, Fleeming Jenkin, found the analogy a weakness in Darwin's theory because of the limited extent of variation in any one direction in domestic animals and plants.64 We have already seen that Darwin had confided a similar view to his notebook thirty years earlier, but changed his mind as a result of his profound study of domesticates. De Beer's reference to “an English country gentleman's knowledge of domestic plants and animals and their breeding”65 fails totally to recognize the originality and depth of Darwin's knowledge of domesticates.Why did Darwin, against the currents of his time, rely so heavily on mankind's experience with domesticated organisms to shape his theory about species in nature? On reason is that only with domesticates was an approach that came close to experimental verification possible. Darwin fully realized the inadequacies of the experiment, as is emphasized by his repeated contrasting of selection under nature and selection by man. Yet the extensive experience and data of plant and animal breeders offered the only reliable base against which Darwin could continually challenge his views. As he wrote in the introduction to Variation, with domestication, “man ... may be said to have been trying an experiment on a gigantic scale.”66 Given Darwin's high opinion of the quantitative work of Malthus and Quetelet (as emphasized by Schweber),67 and his unremitting efforts to secure data by which to test his theories, it was inevitable that he should attach high significance to domesticated varieties. John Tyndall, in his Belfast address of 1874, said: “The strength of the doctrine of Evolution consists, not in experimental demonstration (for the subject is hardly accessible to this mode of proof), but in its general harmony with scientific thought.”68 Darwin would have agreed with the latter thought, but I think he would have challenged the preceding one on the grounds that long experience with domesticated varieties did provide an element of experimental demonstration. It gave him confidence in his theory, and he used his vast knowledge of artificial selection boldly and creatively. (shrink)

In this paper, we explore the literature on cognitive heuristics and biases in light of virtue epistemology, specifically highlighting the two major positions—agent-reliabilism and agent-responsibilism —as they apply to dual systems theories of cognition and the role of motivation in biases. We investigate under which conditions heuristics and biases might be characterized as vicious and conclude that a certain kind of intellectual arrogance can be attributed to an inappropriate reliance on Type 1, or the improper function of Type 2, (...) cognitive processes. By the same token, the proper intervention of Type 2 processes results in the virtuous functioning of our cognitive systems. Moreover, the role of motivation in attenuating cognitive biases and the cultivation of certain epistemic habits points to the tenets of agent-responsibilism.. (shrink)

In this important book, Susan Hurley sheds new light on consciousness by examining its relationships to action from various angles. She assesses the role of agency in the unity of a conscious perspective, and argues that perception and action are more deeply interdependent than we usually assume. A standard view conceives perception as input from world to mind and action as output from mind to world, with the serious business of thought in between. Hurley criticizes this picture, and considers (...) how the interdependence of perceptual experience and agency at the personal level (of mental contents and norms) may emerge from the subpersonal level (of underlying causal processes and complex dynamic feedback systems). Her two-level view has wide implications, for topics that include self-consciousness, the modularity of mind, and the relations of mind to world. The self no longer lurks hidden somewhere between perceptual input and behavioral output, but reappears out in the open, embodied and embedded in its environment. Hurley traces these themes from Kantian and Wittgensteinian arguments through to intriguing recent work in neuropsychology and in dynamic systems approaches to the mind, providing a bridge from mainstream philosophy to work in other disciplines. Consciousness in Action is unique in the range of philosophical and scientific work it draws on, and in the deep criticism it offers of centuries-old habits of thought. (shrink)
