The representation theorems of expected utility theory show that having certain types of preferences is both necessary and sufficient for being representable as having subjective probabilities. However, unless the expected utility framework is simply assumed, such preferences are also consistent with being representable as having degrees of belief that do not obey the laws of probability. This fact shows that being representable as having subjective probabilities is not necessarily the same as having subjective probabilities. Probabilism can be defended on the (...) basis of the representation theorems only if attributions of degrees of belief are understood either antirealistically or purely qualitatively, or if the representation theorems are supplemented by arguments based on other considerations (simplicity, consilience, and so on) that single out the representation of a person as having subjective probabilities as the only true representation of the mental state of any person whose preferences conform to the axioms of expected utility theory.

Australia's Coalition Against Duck Shooting sees duck-shooting as a social problem and as an injustice with moral, legal and environmental consequences. The small animal liberationist group has succeeded in dramatically reducing the numbers of duck shooters in Victoria, which is the home of duck-shooting in Australia. The Coalition's framing work with the public via the electronic media involves three parts: a diagnosis , a prognosis and a motivational frame , all of which construct hunting as a cruel, antisocial blood sport (...) that ought to be banned. In this article, television news bulletins and feature stories from the 1993 and 1994 campaigns are analyzed to show how CADS makes and sustains its claims. In addition to 90 pages of transcripts of news commentaries and descriptive accounts of the visuals, the data include tape-recorded interviews with some of the duck liberationists involved in the campaign.

Probabilistic coherence is not an absolute requirement of rationality; nevertheless, it is an ideal of rationality with substantive normative import. An idealized rational agent who avoided making implicit logical errors in forming his preferences would be coherent. In response to the challenge, recently made by epistemologists such as Foley and Plantinga, that appeals to ideal rationality render probabilism either irrelevant or implausible, I argue that idealized requirements can be normatively relevant even when the ideals are unattainable, so long as they (...) define a structure that links imperfect and perfect rationality in a way that enables us to make sense of the notion of better approximations to the ideal. I then analyze the notion of approximation to the ideal of coherence by developing a generalized theory of belief functions that allows for incoherence, and showing how such belief functions can be ordered with regard to greater or lesser coherence.

There is a widespread feeling that health is special; the rules that are usually used in other policy areas are not applied in health policy. Health economists, for example, tend to be reluctant to offer economists' usual prescription of competition and consumer choice, even though they have largely failed to justify this reluctance by showing that health economics involves special features such as public goods, externalities, adverse selection, poor consumer information, or unusually severe consequences.

We have been discussing some of the fundamental features of the classical calculus of probability. The equiprobability of rival events was seen to be a major assumption of the calculus. Moreover, it is an assumption which the pure mathematician need not bother to justify. He need only present his formal system as follows.

Within the context of the study of the genetics of language, Chomskian laws of grammar, such as theStructure-dependence Condition and theA over A Condition, may be usefully regarded to have a status similar to that of Mendelian Laws in classical genetics. In both the case of Chomsky's Laws and Mendel's Laws, formal genetic principles are postulated which abstract away from the physical mechanisms involved and in both cases certain apparent counterexamples mirror a more complex underlying genetic organisation.

This book highlights some of the principles which should be considered by planners, legislative drafters, and policy-makers as they work to develop legal frameworks on access to genetic resources in their countries. Contextual information on the Convention on Biological Diversity and examples of how countries have approached the issue to date are provided.

In the first section, I consider what several logicians say informally about the notion of logical consequence. There is significant variation among these accounts, they are sometimes poorly explained, and some of them are clearly at odds with the usual technical definition. In the second section, I first argue that a certain kind of informal account—one that includes elements of necessity, generality, and apriority—is approximately correct. Next I refine this account and consider several important questions about it, including the appropriate (...) characterization of necessity, the criterion for selecting logical constants, and the exact role of apriority. I argue, among other things, that there is no need to recognize a special logical sense of necessity and that the selection of terms to serve as logical constants is ultimately a pragmatic matter. In the third section, I consider whether the informal account I have presented and defended is adequately represented by the usual technical definition. I show that it is, and provably so, for certain limited ways of selecting logical constants. In the general case, however, there seems to be no way to be sure that the technical and informal accounts coincide. (shrink)

This article addresses a countermovement to the animal liberation movement and its campaigns against vivisection, factory farming, and recreational hunting in the United States, the United Kingdom, and Australia. As moderate welfarists, pragmatic animal liberationists , and radical abolitionists who advocate animal rights, animal protectionists campaign for animals. The countermovement defends acts that animal protectionists decry. Meanwhile, sociologists accord little study to interplay between the movements . In Buechler's and Cylke's collection of 34 papers on social movements , only one (...) paper focused on countermovements, describing the connection between social movement and countermovement as "a continuous dialect of social change" . Although extensive writings exist on the main campaigns of the animal liberation movement, little scholarly material exists on the defenses mounted by the countermovement. This article examines key elements of a values war, a struggle over moral capital waged by animal protectionists and their countermovement opponents. (shrink)

Using the results of a survey of animal rights activists, advocates, and supporters, the paper reveals much more convergence than divergence of attitudes and actions by male and female animal protectionists. Analysis of the divergence suggests that the differences between men and women in the movement are contingent upon such things as early socialization, gendered work and leisure patterns, affinity with companion animals, ambivalence about science, and a history of opposition to nonhuman animal abuse by generations of female activists and (...) animal advocates. Aside from the feminist and women's movements and groups like Mothers Against Drunk Driving, it is rare to find a social movement in which the standing of women eclipses those of their male colleagues. The paper suggests that animal protection remains a bastion of female activism and advocacy because women care about blood, flesh, and pain and, unlike earlier generations of animal activists, no longer are seen as a liability to the success of the movement.

This paper profiles the animal activism of the late American animal activist Henry Spira, whose campaign strategies and tactics suggest a number of links with the nineteenth century pioneers of animal protection as well as with approaches favored by contemporary animal activists. However, the article argues that Spira's style of animal advocacy differed from conventional approaches in the mainstream animal movement in that he preferred to work with, rather than against, animal user industries. To this end, he pioneered the use (...) of "reintegrative shaming" in animal protection, an accommodation strategy that relied on moralizing with opponents as opposed to the more common approach in animal advocacy of adversarial vilification, and hence, disintegrative shaming. The article describes the framing of some of Spira's best-known anti-cruelty campaigns and his use of reintegrative shaming to induce animal users to change their ways. (shrink)

History of science and philosophy of science are not logically related: to claim that they are would be either to underestimate or to misunderstand the genetic fallacy. But one risk of inferring that there is no connection at all between the two is the risk that philosophers of science may not know what they are talking about. The philosopher of science who does not know intimately the history of the scientific problem with which he is exercised may be discussing no (...) genuine state of affairs. On the other hand, The historian and philosopher of science are both concerned with the structure of scientific ideas, And these concerns are fused into one when the scientific "argumentation" of the past is the issue.

The simulation hypothesis claims that the whole observable universe, including us, is a computer simulation implemented by technologically advanced beings for an unknown purpose. The simulation argument (as I reconstruct it) is an argument for this hypothesis with moderately plausible premises. I develop two lines of objection to the simulation argument. The first takes the form of a structurally similar argument for a conflicting conclusion, the claim that I am a so-called freak observer, formed spontaneously in a quantum or thermodynamic (...) fluctuation rather than through ordinary processes of evolution and growth. The second rejects the basic line of reasoning of both arguments: the sort of evidence they cite is not capable of supporting either the claim that I am a simulant or the claim that I am a freak observer. The evidence that simulants or freak observers exist is not a reason to think that I am one of them. (shrink)

On a rainy day in May 1988, a lowland gorilla named Willie B. stepped outdoors for the first time in twenty-seven years, into a new landscape immersion exhibit. Born in Africa, Willie B. had been captured by an animal collector and sold to a zoo. During the decades he spent in a cage, zoos stopped collecting animals from the wild and Americans changed the ways they wished to view animals in the zoo. Zoos developed new displays to simulate landscapes like (...) the Amazon River basin and African forests. Exhibits similar to animals' natural habitats began to replace old-fashioned animal houses. But such displays are only the most recent effort of zoos to present their audiences with an authentic experience of nature. Since the first zoological park opened in the United States in Philadelphia in 1874, zoos have promised their visitors a journey into the natural world. And for more than a century they have been popular places for education and recreation: every year more than 130 million Americans go to zoos to look at the animals and enjoy a day outdoors. The first book-length history of American zoos, Animal Attractions examines the meaning of nature in the city by looking at the ways zoos have assembled and displayed their animal collections. Situated literally and culturally in the American middle landscape, zoos are concrete expressions of longstanding tensions between wildness and civilization, science and popular culture, education and entertainment. In their efforts to promote nature appreciation, they reveal much about how our culture envisions the natural world and the human place in it and how these ideas have changed. (shrink)

Centralised, compliance-focused approaches to research ethics have been normalised in practice. In this paper, we argue that the dominance of such systems has been driven by neoliberal approaches to governance, where the focus on controlling and individualising risk has led to an overemphasis of decontextualised ethical principles and the conflation of ethical requirements with the documentation of ‘informed consent’. Using a UK-based case study, involving a point-of-care-genetic test as an illustration, we argue that rather than ensuring ethical practice such compliance-focused (...) approaches may obstruct valuable research. We call for an approach that encourages researchers and research communities—including regulators, ethics committees, funders and publishers of academic research—to acquire skills to make morally appropriate decisions, and not base decision-making solely on compliance with prescriptive regulations. We call this ‘ethical preparedness’ and outline how a research ethics system might make space for this approach. (shrink)

Motivated by a characterization of weakly compact cardinals due to Todorcevic, we introduce a new cardinal characteristic, the C-sequence number, which can be seen as a measure of the compactness of a regular uncountable cardinal. We prove a number of ZFC and independence results about the C-sequence number and its relationship with large cardinals, stationary reflection, and square principles. We then introduce and study the more general C-sequence spectrum and uncover some tight connections between the C-sequence spectrum and the strong (...) coloring principle U(. . .), introduced in Part I of this series.

Viale introduced covering matrices in his proof that SCH follows from PFA. In the course of the proof and subsequent work with Sharon, he isolated two reflection principles, CP and S, which, under certain circumstances, are satisfied by all covering matrices of a certain shape. Using square sequences, we construct covering matrices for which CP and S fail. This leads naturally to an investigation of square principles intermediate between □κ and □ for a regular cardinal κ. We provide a detailed (...) picture of the implications between these square principles. (shrink)

We investigate questions involving Aronszajn trees, square principles, and stationary reflection. We first consider two strengthenings of introduced by Brodsky and Rinot for the purpose of constructing κ‐Souslin trees. Answering a question of Rinot, we prove that the weaker of these strengthenings is compatible with stationary reflection at κ but the stronger is not. We then prove that, if μ is a singular cardinal, implies the existence of a special ‐tree with a cf(μ)‐ascent path, thus answering a question of Lücke.

Generic language (e.g., “tigers have stripes”) leads children to assume that the referenced category (e.g., tigers) is inductively informative and provides a causal explanation for the behavior of individual members. In two preregistered studies with 4- to 7-year-old children (N = 497), we considered the mechanisms underlying these effects by testing how correcting generics might affect the development of these beliefs about novel social and animal kinds (Study 1) and about gender (Study 2). Correcting generics by narrowing their scope to (...) a single individual limited beliefs that the referenced categories could explain what their members would be like while broadening the scope to a superordinate category (Study 2) uniquely limited endorsement of gender norms. Across both studies, correcting generics did not alter beliefs about feature heritability and had mixed effects on inductive inferences, suggesting that additional mechanisms (e.g., causal reasoning about shared features) contribute to the development of full-blown essentialist beliefs. These results help illuminate the mechanisms by which generics lead children to view categories as having rich inductive and causal potential; in particular, they suggest that children interpret generics as signals that speakers in their community view the referenced categories as meaningful kinds that support generalization. The findings also point the way to concrete suggestions for how adults can effectively correct problematic generics (e.g., gender stereotypes) that children may hear in daily life. (shrink)

Though the literature on the topic has been slim, several recent commentators have identified a close affinity between the philosophical project of Giorgio Agamben, as articulated in his Homo Sacer series, and René Girard's theory of mimetic rivalry with its resolution through sacrificial scapegoating.1 Both are theories of social unity made possible through highly ritualized forms of exclusion. Girard's work posits desire and its conflictual consequences as the ultimate ground for all social systems, while Agamben views the same systems with (...) an eye toward the maintenance of sovereign power. Agamben begins his study with an obscure figure of Roman law, the "sacred man," who is excluded from the laws of both the... (shrink)

In the completely unregulated microcomputer industry, ethical restrictions to business are often self imposed or put in place by the suppliers of product.

It is the history of one product's success in the Canadian marketplace, from the U.S. vendor, to the Canadian distributor, to computer dealers, to the end-user. The focus is on an authorization program, applied after the fact, to a local market which was unwilling (...) to abide by the program's good intent. (shrink)

When attempting to answer the question, in the context of clinical healthcare, one might be tempted to leap to either of two rather obvious, but seemingly contradictory conclusions. On the one hand, we might have a general impression of religion not making much of a distinctive and clear difference, at least in the actions and outcomes of most cases of clinical interaction. Those of us in the bioethics world of discourse are likely to think only of the less common cases (...) of Christian Scientists, Jehovah's Witnesses, Orthodox Jews, or certain religious groups who seem to the majority of the population to hold especially sectarian, if not beliefs about medical matters. The so-called mainstream religious groups do not get much attention because they largely don't cause much trouble ; they have learned to bracket their religious commitments from at least any professional settings ; or they don't hold views entailing consequences any different from those of most nonbelieving, generally upright individuals. Furthermore, although religious believers may have some distinctive views, these views don't often noticeably manifest themselves in distinctive or significant ways. (shrink)

We address three questions raised by Cummings and Foreman regarding a model of Gitik and Sharon. We first analyze the PCF-theoretic structure of the Gitik–Sharon model, determining the extent of good and bad scales. We then classify the bad points of the bad scales existing in both the Gitik–Sharon model and other models containing bad scales. Finally, we investigate the ideal of subsets of singular cardinals of countable cofinality carrying good scales.

We give a formalism for approximate isomorphism in continuous logic simultaneously generalizing those of two papers by Ben Yaacov [2] and by Ben Yaacov, Doucha, Nies, and Tsankov [6], which are largely incompatible. With this we explicitly exhibit Scott sentences for the perturbation systems of the former paper, such as the Banach‐Mazur distance and the Lipschitz distance between metric spaces. Our formalism is simultaneously characterized syntactically by a mild generalization of perturbation systems and semantically by certain elementary classes of two‐sorted (...) structures that witness approximate isomorphism. As an application, we show that the theory of any ‐tree or ultrametric space of finite radius is stable, improving a result of Carlisle and Henson [8]. (shrink)

The Philosophy for Children in Schools Project is an ongoing research project to explore the impact of philosophy for children on classroom practice. This paper reports on the responses of head teachers, teachers and local educational authority officers in South Wales, UK, to the initial training programme in Philosophy for Children carried out by the University School of Education. Achieving change in schools through the embedding of new practices is an important challenge for head teachers. Interviews and qualitative questionnaires were (...) used to explore perceptions of and attitudes towards the dialogic practice of P4C and the related challenges for school leaders. The results provide an insight into how head teachers planned to embed the new practice of P4C in their schools. Results from the interviews and questionnaires have been subject to iterative analysis and categories derived under which to discuss the findings. There are many similarities in the ways in which different head teachers go about planning change n their schools as well as differences. The results provide insight into the role of initial continuing professional development in school development and the processes by which individual heads plan to embed change in practice across the whole school.

Randomized controlled clinical trials play an important role in the development of new medical therapies. There is, however, an ethical issue surrounding the use of randomized treatment allocation when the patient is suffering from a life threatening condition and requires immediate treatment. Such patients can only benefit from the treatment they actually receive and not from the alternative therapy, even if it ultimately proves to be superior. We discuss a novel new way to analyse data from such clinical trials based (...) on the use of the recently developed theory of imprecise probabilities. This work draws an explicit distinction between the related but nevertheless distinct questions of inference and decision in clinical trials. The traditional question of scientific interest asks 'Which treatment offers the greater chance of success?' and is the primary reason for conducting the clinical trial. The question of decision concerns the welfare of the patients in the clinical trial, asking whether the accumulated evidence favours one treatment over the other to such an extent that the next patient should decline randomization and instead express a preference for one treatment. Consideration of the decision question within the framework of imprecise probabilities leads to a mathematical definition of equipoise and a method for governing the randomization protocol of a clinical trial. This paper describes in detail the protocol for the conduct of clinical trials based on this new method of analysis, which is illustrated in a retrospective analysis of data from a clinical trial comparing the anti-emetic drugs ondansetron and droperidol in the treatment of postoperative nausea and vomiting. The proposed methodology is compared quantitatively using computer simulation studies with conventional clinical trial designs and is shown to maintain high statistical power with reduced sample sizes, at the expense of a high type I error rate that we argue is irrelevant in some specific circumstances. Particular emphasis is placed on describing the type of medical conditions and treatment comparisons where the new methodology is expected to provide the greatest benefit. (shrink)

The growing interest in dual‐inheritance models of human evolution has focused attention on culture as a means by which ancestors transmitted acquired phenotypic characteristics to their descendants. The ability of cultural behaviors to be repeatedly transmitted from ancestors to descendants enables individuals to influence their descendant‐leaving success over many more generations than are usually coclusive fitness. This essay proposes that traditional stories, or myths, can be seen as a way in which ancestors influence their descendant‐leaving success by influencing the behavior (...) of many generations of their descendants. The myth of Oedipus is used as an example of a traditional story aimed at promoting proper behavior and cooperation among kin. This interpretation of the Oedipus myth is contrasted with Freudian and structuralist interpretations. (shrink)

In this essay, I analyze and critique Richard Jeffrey's radical probabilism. The basic theses defining it are examined, particularly the idea that probabilistic coherence involves a kind of "consistency." The main challenges to Jeffrey's view are (1) that there is an inconsistency between regarding probabilities as subjective and some probabilistic judgments as better than others, and (2) that decision theory so conceived has no normative import. I argue that both of these challenges can be met.

Essay review of John Carroll's book, _Laws of Nature_.

In a recent discussion article in this journal, Gila Sher responds to some of my criticisms of her work on what she calls the formal-structural account of logical consequence. In the present paper I reply and attempt to advance the discussion in a constructive way. Unfortunately, Sher seems to have not fully understood my 1997. Several of the defenses she mounts in her 2001 are aimed at views I do not hold and did not advance in my 1997. Most prominent (...) among these are her claims that I reject the formal-structural account, because it licenses “unnatural” logical constants, and that I consider the “truth-functional criterion” for connectives “a paradigm of a successful criterion of logicality”. Both of these claims are simply false, as even a moderately careful reading of my 1997 will show. Other charges she makes have some basis in fact but are inaccurate. For example, she says that I claim that FS is “neutral with regard to the apriority of logic,” and that this neutrality “renders it inconsistent”. What I actually say is that Sher’s acceptance of the neutrality in question is “inconsistent with part of the legacy of Tarski, a legacy that she finds very congenial”, not that FS itself is inconsistent. More interestingly, she misunderstands my claim about the apriority of logic, and clarification of this misunderstanding suggests two distinct ways in which logic might be held to be free of empirical influence. It is also noteworthy that Sher’s statements about the apriority of logic constitute both a change in the position she took in her 1991 and, although she seems not to realize it, an admission that she does not take issue with one of my major criticisms.
