In this article we report the findings of a randomised control clinical trial that assessed the impact of a Philosophy for Children program and replicated a previous study conducted in Scotland by Topping and Trickey. A Cognitive Abilities Test was administered as a pretest and a posttest to randomly selected experimental groups and control groups. The students in the experimental group engaged in philosophy lessons in a setting of structured, collaborative inquiry in their language arts classes for one hour per (...) week for a number of weeks. The control group received the standard language arts curriculum in that one hour. The study found that the seventh grade students who had experienced the P4C program showed significant gains relative to those in the seventh grade control group at a high level of statistical significance, but the eighth grade students in the experimental group did not show such gains over the eighth grade control group. It was discovered that the seventh grade teachers started the program early in the school year and continued it for a period of 22 to 26 weeks, while the eighth grade teachers started much later and used the program for only 4 to 10 weeks. Our findings suggest that the P4C program must involve students in activities for a significant period of time before the program shows results, but that a meaningful impact on students’ cognitive abilities can be achieved in about 24 weeks of lessons, less than half the time evidenced by the study by Topping and Trickey.

Three recent research reports by Topping and Trickey, by Fair and colleagues, and by Gorard, Siddiqui and Huat See have produced data that support the conclusion that a Philosophy for Children program of one-hour-per-week structured discussions has a marked positive impact on students. This article presents data from a follow up study done three years after the completion of the study reported in Fair et al.. The data show that the positive gains in scores on the Cognitive Abilities (...) Test were still present and had not faded after three years. Given the strength of these confirmations of the positive durable impact of the P4C program of structured discussions and given the relatively low cost of implementing the P4C program, it is recommended that it become a standard part of the school curriculum.

In this article I explore two accounts of the Fallacy of Many Questions made famous by the question "Have you stopped beating your wife?" The accounts are from the works of Lennart Aqvist and Noel Belnap, and the two authors differ in their accounts of the fallacy. Then I give my own account based on understanding a facet of erotetic logic, i. e., the logic of questions.

In lieu of an abstract, here is a brief excerpt of the content:Buddhism, Christianity, and Modern Science:A Response to Masao AbeFrank FairAfter number of years of teaching philosophy of science, a few years ago I took up the challenge of teaching philosophy of religion. As one might imagine, it has always seemed to me to be important that our religious convictions harmonize with our best scientific knowledge of how the world works, and this became a more interesting issue when the (...) change in my teaching assignment brought me into contact with the work of Masao Abe, the eminent Japanese Buddhist scholar. His essay "Religion and Science in the Global Age—Their Essential Character and Mutual Relationship" (Abe 1985: 241–248) challenged me to expand my thinking to consider not only how theistic religions such as Christianity relate to science, but also to consider how nontheistic religions, such as Buddhism, might fare when interacting with modern science.In his essay on religion and science Abe expressed his agreement with the thought of Keiji Nishitani in this way:1. It is necessary for each religion to re-examine the basis of its world view. For any religion its world view is not like clothes that one can change whenever one pleases. A world view is to religion what water is to a fish. It is the indispensable condition through which religion can actually come into existence. Water is neither the life of the fish as such, nor its body, yet it is fundamentally linked to both. For a religion to change its world view is a matter no less fatal to it than for a fish to change from salt water to fresh.2. What is even more crucial and important is that each religion re-examine and reinterpret that tradition's understanding of God or the 'ultimate' and His or its relation to human beings and the world. With regard to this second point, Buddhism which is fundamentally non-theistic, is in a somewhat different situation from Christianity, which is basically theistic. (Abe 1985: 244–245)Abe continues: "Theistic answers to the question 'why' in Christianity, such as the 'will of God' and the 'rule of God' are incompatible with modern scientific answers to the question 'how.' This is because the former strongly emphasize the personality of the ultimate while the latter is essentially impersonal" (Abe 1985: 245). In this [End Page 67] discussion, I will follow Abe's lead and consider the question of whether Buddhism is more compatible with modern science than Christianity.Christianity and Modern Science: Tensions and HarmoniesOne set of issues causing tension between modern science and Christianity has to do with history. Briefly, ideas about the creation of the universe, about the special creation of humankind, and about miracles, as in the claims about the resurrection of Jesus, are ideas about the action of God in history. These ideas relate the stance that Abe attributed to Christianity as involving an attempt to answer "why" questions about meaning and purpose, an attempt which he feels brings Christianity into conflict with modern science. I will give a brief account of what I take to be the current state of the discussion about each of these matters, and my point is to argue that Abe's conclusion about the relative superiority of Buddhism over Christianity in relation to modern science is premature at best.The Creation of the UniverseThe rise of the Big Bang theory, which traces the origin of the universe back to a tremendously powerful event several billion years ago, at first gave comfort to traditional ideas of divine creation. However, it soon became apparent that this comfort was ambiguous at best. It was not clear, for instance, that one could really prove on the basis of observational evidence that there was an absolute starting point those many billions of years ago, or whether the totality of things could be going through a huge set of cycles. Then there is the issue that even if there is a "First Cause" responsible for the Big Bang, this does not automatically give evidence that the First Cause is a personal being who cares about us or has any immediate involvement in our lives. The First Cause... (shrink)

When the accrediting association for collegiate schools of business, AACSB International, reformulated its accreditation standards to include a systematic assessment of undergraduates’ progress in analytic and reflective thinking, our interdisciplinary team looked at available instruments.

Recently, unrestrained consequentialism has been defended against the charge that it leads to unacceptable trade-offs by showing a tradeoff accepted by many of us is not justified by any of the usual nonconsequenlist arguments. The particular trade-off involves raising the speed limit on the Interstate Highway System. As a society, we seemingly accept a trade-off of lives for convenience. This defense of consequentialism may be a tu quoque, but it does challenge nonconsequentialists to adequately justify a multitude of social decisions. (...) Work by the deontologist Frances Kamm, conjoined with a perspective deployed by several economists on the relation between social costs and lives lost, is relevant. It provides a starting point by justifying decisions which involve trading lives only for other lives. But the perspective also recognizes that using resources in excess of some figure to save a life causes us to forego other live-saving activities, thus causing a net loss of life. Setting a speed limit as low as 35 miles per hour might indeed save some lives, but the loss of productivity due to the increased time spent in travel would cost an even greater number of lives. Therefore, many trade-offs do not simply involve trading lives for some lesser value, but are justified as allowing some to die in order to save a greater number. (shrink)

The major stakeholder classes in education have three distinct ways by which they judge the quality of knowledge claims. At times this can cause considerable distraction or mis-communication among stakeholders.

Algorithmic decision-making increasingly shapes people's daily lives. Given that such autonomous systems can cause severe harm to individuals and social groups, fairness concerns have arisen. A human-centric approach demanded by scholars and policymakers requires considering people's fairness perceptions when designing and implementing algorithmic decision-making. We provide a comprehensive, systematic literature review synthesizing the existing empirical insights on perceptions of algorithmic fairness from 58 empirical studies spanning multiple domains and scientific disciplines. Through thorough coding, we systemize the current empirical literature along (...) four dimensions: (1) algorithmic predictors, (2) human predictors, (3) comparative effects (human decision-making vs. algorithmic decision-making), and (4) consequences of algorithmic decision-making. While we identify much heterogeneity around the theoretical concepts and empirical measurements of algorithmic fairness, the insights come almost exclusively from Western-democratic contexts. By advocating for more interdisciplinary research adopting a society-in-the-loop framework, we hope our work will contribute to fairer and more responsible algorithmic decision-making. (shrink)

Excerpt from L'Énigme du Monde Et Sa Solution Selon Charles Secrétan Mème qui n'ont vu que son portrait, en gardent l'impression. Il était grand par la taille, par la vigueur, par l'activité corporelle. Il savait faire honneur à un bon repas et déguster les vins exquis du canton de Vaud il était fin gourmet, en mème temps que beau mangeur. N'allez pas croire cependant qu'il bornât son horizon aux plaisirs de la table. Il fut toute sa vie un mar cheur (...) intrépide, un admirateur passionné de la nature. Il avait soixante-dix-sept ans quand j'eus le privilège de lui servir de guide dans une course de montagne à douze cents mètres d'altitude. Il marchait avec une tranquille assu rance et semblait se baigner dans l'atmosphère des hauteurs. Il a raconté lui-mème quelques unes de ses plus belles promenades dans un petit livre intitulé Paysages Vaudois.

Il est judicieux de faire appel au concept heideggérien de Gestell – « dispositif », « arraisonnement » – pour observer et interpréter les figures contemporaines de la violence : celle qui est faite non seulement aux hommes, mais plus généralement à la Terre tout entière, aux natures comme aux cultures qui se voient détruites ou empêchées de se déployer librement. Mais il y a à distinguer entre deux questions : celle de l’exacerbation de la violence – qui advient lorsque (...) celle-ci s’industrialise – et celle, fort complexe, de ses origines. Lorsqu’il s’agit de prendre en compte l’origine raciste des politiques de purification ethniques qui ont structuré l’extermination de masse au xx e siècle, en particulier sous le nazisme, l’interprétation heideggérienne de la violence se révèle des plus problématiques.

Although canon-formation is, as Lecker suggests, a product of rhetoric and textual choices of critics, it is also a product of economic forces, political conflicts, and cultural expectations of coherence, “order,” and unitary explanation. Conditioned by some or all of these, an essay ostensibly skeptical of canons, as this one appears to be, can find itself nevertheless contributing to the thing it questions. In attempting to attribute the formation of a single national canon to a specific period , to a (...) specific and allegedly homogeneous group of actors , and to a specific social phenomenon , Lecker’s essay becomes another constructor of canonical text and theory. Behind its arguments that a canon suddenly came into being are fairly precise assumptions not only about “Canadian critics” but also about what constitutes canonicity, and about the relative legitimacy of canonicity claims. “At the end of World War II, Canadian literature was not taught as an independent subject in Canadian schools. There was no canon,” his essay begins . Is a school curriculum the only possible context for the attainment of literary “legitimacy”? Can there be no canon if a literature has no curriculum, education publishers, or “academic critics,” or if it has not been institutionalized as an “independent” subject? Frank Davey, chair of the department of English at York University, is the author of From There to Here: A Guide to English Canadian Literature Since 1960 , Surviving the Paraphrase , Margaret Atwood: A Feminist Poetics , and Reading Canadian Reading . He is also the editor of Open Letter and the on-line magazine Swiftcurrent. He is currently working on a study of nationalist ideologies in Canadian fiction entitled National Arguments. (shrink)

Ce livre propose d'aller au plus intime de la pensée heideggerienne dans sa maturité, qui récapitule ses moments clefs au sein de la constellation des quatre : les dieux, les mortels, la terre et le ciel ; pour découvrir, comme vérité de la relation entre eux, la dimension divine, disposée, dispensée, plurivoque et déterminante dans l'avènement à partir de l'événement appropriant, l'Ereignis. Arriver à cet envoi destinal du divin comme essentiel à la pensée de Heidegger, n'a pu se faire, qu'en (...) prenant d'abord le chemin du dieu heideggerien, pour en dégager le sens et le dépasser vers son fondement puis ce qui a rendu ce dernier possible : ce sur quoi il repose, même dans un oubli, dont les textes ne donnent le sens que sous des moments précis, aboutissant, dans leur être-ensemble et les-uns-pour-les-autres, à l'installation d'un monde par l'Ereignis sous le signe du divin. Il a fallu donc dégager ce qu'est le dieu de ses sens accumulés - en passant par le Dieu créateur, au dieu qui sauvegarde puis au dieu Inconnu - pour retrouver ce qui le donne comme tel, et ensuite chercher la trace de ce don. Ce travail nous a permis de déceler, au fur des textes - non sans surprise et même quelque joie - les traces et les opérations du divin auprès de chacun des éléments de ce qui est devenu le Quadriparti. Une fois ce dégagement effectué avec le plus de précision possible, nous avons pu en identifier les modalités au sein du Geviert, sa manière de " s'installer ", toujours différente, et ses conséquences sur le monde et le destinal. Cela nous a permis enfin d'entreprendre un changement éclairant dans le sens de plusieurs topoi heideggeriens, à savoir l'histoire, l'art, la parole et le poème - éclairage qui donne à chacun son sens fondamental depuis l'expression divine. Ce travail se veut aussi, dans ses dernières pages, un questionnement renouvelé sur les problèmes fondamentaux du divin chez Heidegger, et demande donc de reprendre les textes dans une la perspective qu'il ouverte pour en développer toute la portée.

The secession of prosperous regions may negatively affect the redistributive scheme of an established state. As a consequence, the capacity of its welfare system to support the inhabitants of poorer regions may be significantly reduced. Some authors assert that affluent groups who opt for full political independence violate duties of solidarity. This objection to the secession of prosperous regions can be based on different views of distributive justice. Here, following a distinction that has been introduced by Allen Buchanan, ‘subject centred’ (...) and ‘justice as reciprocity’ theories are explored. It is argued that both theories fail to support the case against the secession of wealthy groups. ‘Subject centred’ theories cannot explain special duties toward compatriots, whereas ‘justice as reciprocity’ theories cannot justify restrictions on exit rights. However, this does not mean that separatists have no moral duties vis-à-vis their fellow citizens. They are obliged to dissolve the political union in a fair way, e.g., by accepting responsibility for some share of the public debts. (shrink)

This article offers a normative framework for affirmative action. It argues that affirmative action is not about diversity, but correcting historical injustice. The theory’s presumption is that racial groups would perform equally if not for history, because talent and hard work do not vary by race. The article explores the implications of that premise in answering the most provocative criticisms of affirmative action. Should white students pay for historical wrongs? Should African immigrants benefit from affirmative action? Are Asian Americans unfairly (...) disadvantaged? The article proposes proportional representation as a limiting principle of affirmative action, because preferential treatment beyond proportionality contradicts the theory’s presumption of equal performance. The article proceeds to argue that some groups, like Asian Americans, rebut the presumption by fairly outperforming others and should not be penalized. Finally, the article argues that groups should not be classified on race per se, rather on a shared experience of injustice. (shrink)

La conception qu'Emmanuel Kant se faisait des mathematiques etait en parfaite consonance avec l'opinion philosophique la plus courante au XVIIIe siecle a l'egard de cette science. Il conviendrait par consequent de tenir davantage compte de l'histoire des idees scientifiques, ce qui permettrait de faire remarquer que la pensee kantienne releve d'un paradigme scientifique plus ancien, celui de la geometrie euclidienne (ou l'image reste intimement articulee au signe), alors que les critiques ordinairement adressees au Kant mathematicien s'appuient indirectement sur l'heritage de (...) la revolution algebrique par lequel le signe est desormais dissocie de l'image. Il convenait donc d'examiner dans le plus grand detail la maniere dont, a travers son oeuvre, Kant recevait et discutait les conceptions mathematiques de son temps, et en particulier la tension marquee entre la geometrie et l'arithmetique. Ce faisant, il redevient possible de recontextualiser le concept kantien d'intuition par rapport aux evidences de son temps, qui ne sont plus tout a fait les notres. Les reticences de Kant vis-a-vis des concepts les plus problematiques de l'algebre se laissent ainsi interpreter a nouveaux frais, faisant ressortir la signification de l'architectonique. (shrink)

Although risk and uncertainty are inevitable aspects of the sustainability problem, they are often neglected in the sustainability discourse, especially in the economic analysis of sustainable development. We argue that this deprives the sustainability discourse of interesting connections to risk management. We show that defining sustainability as the obligation to limit the risk of harming future individuals provides a framework in which tools from risk management, like mean-variance analysis, can be employed to analyze planning decisions and to calculate a risk-minimizing (...) policy mix. Furthermore, we discuss whether such a notion of sustainability can be an ethically tenable sustainability concept and how a positive probability of harming future individuals might be defended.

A première vue, la différence que Kant fait dans sa Critique de la raison pure entre jugements particulier et singulier semble être dénuée d’une véritable importance philosophique. D’ailleurs, dans cette même veine, l’on s’est demandé très tôt s’il fallait vraiment que les catégories soient regroupées par trois plutôt que par deux, puisque la troisième semble résulter de la connexion des deux autres, et c’est l’observation que le fidèle Johann Schultz s’enhardira à faire respectueusement au philosophe dans une lettre de 1784 (...) dont nous aurons à reparler. Entre-temps, l’on s’est habitué: le caractère tout d’abord déconcertant de l’architectonique kantienne est ce qui disparaît à l’usage, sinon à l’usure; et s’il ne perd rien de son caractère insolite aux yeux des générations d’étudiants qui se penchent avec perplexité sur ces pages sacrées, cet «art des systèmes» paraît un décor baroque que l’on finit par oublier par la force de l’habitude pour se concentrer sur ce qui ferait office d’intrigue et peut se raconter à qui n’aurait pas lu l’oeuvre.

Most experts would agree that the current medical malpractice system in the United States does not work effectively either to compensate victims fairly or prevent injuries caused by medical errors. Policy responses to a series of medical malpractice crises have not resulted in effective reform and have not altered the fundamental incentives of the stakeholders. In Medical Malpractice, economist Frank Sloan and lawyer Lindsey Chepke examine the U.S. medical malpractice process from legal, medical, economic, and insurance perspectives, analyze past (...) efforts at reform, and offer realistic, achievable policy recommendations. They review the considerable empirical evidence in a balanced fashion and assess objectively what works in the current system and what does not. Sloan and Chepke argue that the complexity of medical malpractice stems largely from the interaction of the four discrete markets that determine outcomes--legal, medical malpractice insurance, medical care, and government activity. After describing what the evidence shows about the functioning of medical malpractice, types of defensive medicine, and the effects of past reforms, they examine such topics as scheduling damages as an alternative to flat caps, jury behavior, health courts, incentives to prevent medical errors, insurance regulation, reinsurance, no-fault insurance, and suggestions for future reforms. Medical Malpractice is the most comprehensive treatment of malpractice available, integrating findings from several different areas of research and describing them accessibly in nontechnical language. It will be an essential reference for anyone interested in medical malpractice.Frank A. Sloan is J. Alexander McMahon Professor of Health Policy and Management and Professor of Economics at Duke University. He is the coauthor of The Price of Smoking and author or editor of many other books on health economics. Lindsey M.
