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.

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.

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 this book, which thoroughly revises and greatly expands his classic work Sameness and Substance, David Wiggins retrieves and refurbishes in the light of twentieth-century logic and logical theory certain conceptions of identity, of substance and of persistence through change that philosophy inherits from its past. In this new version, he vindicates the absoluteness, necessity, determinateness and all or nothing character of identity against rival conceptions. He defends a form of essentialism that he calls individuative essentialism, and then a (...) form of realism that he calls conceptualist realism. In a final chapter he advocates a human being-based conception of the identity and individuation of persons, arguing that any satisfactory account of personal memory must make reference to the life of the rememberer himself. This important book will appeal to a wide range of readers in metaphysics, philosophical logic, and analytic philosophy. (shrink)

Lipsey and Lancaster's "general theory of second best" is widely thought to have significant implications for applied theorizing about the institutions and policies that most effectively implement abstract normative principles. It is also widely thought to have little significance for theorizing about which abstract normative principles we ought to implement. Contrary to this conventional wisdom, I show how the second-best theorem can be extended to myriad domains beyond applied normative theorizing, and in particular to more abstract theorizing about the normative (...) principles we should aim to implement. I start by separating the mathematical model used to prove the second-best theorem from its familiar economic interpretation. I then develop an alternative normative-theoretic interpretation of the model, which yields a novel second best theorem for idealistic normative theory. My method for developing this interpretation provides a template for developing additional interpretations that can extend the reach of the second-best theorem beyond normative theoretical domains. I also show how, within any domain, the implications of the second-best theorem are more specific than is typically thought. I conclude with some brief remarks on the value of mathematical models for conceptual exploration. (shrink)

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.

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.

Artificial intelligence has historically been conceptualized in anthropomorphic terms. Some algorithms deploy biomimetic designs in a deliberate attempt to effect a sort of digital isomorphism of the human brain. Others leverage more general learning strategies that happen to coincide with popular theories of cognitive science and social epistemology. In this paper, I challenge the anthropomorphic credentials of the neural network algorithm, whose similarities to human cognition I argue are vastly overstated and narrowly construed. I submit that three alternative supervised learning (...) methods—namely lasso penalties, bagging, and boosting—offer subtler, more interesting analogies to human reasoning as both an individual and a social phenomenon. Despite the temptation to fall back on anthropomorphic tropes when discussing AI, however, I conclude that such rhetoric is at best misleading and at worst downright dangerous. The impulse to humanize algorithms is an obstacle to properly conceptualizing the ethical challenges posed by emerging technologies. (shrink)

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.

A collection of 14 essays honoring the life and work of Oxford philosopher Wiggins touching on topics from ancient philosophy to ethics, metaphysics and the theory of meaning. The contributing scholars debate many of the seminal issues of Wiggins' work, including the determinancy of distinctness, relative identity, naturalism in ethics, logic and truth in moral judgments, and the practical wisdom of Aristotle. The collection uniquely features replies by Wiggins to each of the papers. Annotation copyright by Book News, Inc., Portland, (...) OR. (shrink)

Drawing on work of the past decade, this volume brings together articles from the philosophy, history, and sociology of science, and many other branches of the biological sciences. The volume delves into the latest theoretical controversies as well as burning questions of contemporary social importance. The issues considered include the nature of evolutionary theory, biology and ethics, the challenge from religion, and the social implications of biology today (in particular the Human Genome Project).

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)

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)

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)

According to dispositionalism about modality, a proposition <p> is possible just in case something has, or some things have, a power or disposition for its truth; and <p> is necessary just in case nothing has a power for its falsity. But are there enough powers to go around? In Yates (2015) I argued that in the case of mathematical truths such as <2+2=4>, nothing has the power to bring about their falsity or their truth, which means they come out both (...) necessary and not possible. Combining this with axiom (T), it is easy to derive a contradiction. I suggested that dispositionalists ought to retreat a little and say that <p> is possible just in case either p, or there is a power to bring it about that p, grounding the possibility of mathematical propositions in their truth rather than in powers. Vetter’s (2015) has the resources to provide a response to my argument, and in her (2018) she explicitly addresses it by arguing for a plenitude of powers, based on the idea that dispositions come in degrees, with necessary properties a limiting case of dispositionality. On this view there is a power for <2+2=4>, without there being a power to bring about its truth. In this paper I argue that Vetter’s case for plenitude does not work. However, I suggest, if we are prepared to accept metaphysical causation, a case can be made that there is indeed a power for <2+2=4>. (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)

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. This article addresses the problems which can arise from the implementation of authorization programs. 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)

Why study notations, diagrams, or more broadly the variety of nonverbal “representations” or “signs” that are used in mathematical practice? This chapter maps out recent work on the topic by distinguishing three main philosophical motivations for doing so. First, some work (like that on diagrammatic reasoning) studies signs to recover norms of informal or historical mathematical practices that would get lost if the particular signs that these practices rely on were translated away; work in this vein has the potential to (...) broaden our view of the specific normativity of mathematics beyond logical proof. Second, some work focuses on signs to highlight the open-ended and “nonrigorous” aspects of mathematical practice, and the role of these aspects in the historical development of mathematics. The third motivation is based on the following observation: the reason differences in signs matter in mathematics is that humans are finite agents, with cognitive and computational limitations. Accordingly, studying signs can be a way to study how human computational constraints shape the mathematics that we do, and to tackle the topic of mathematical understanding. (shrink)

The typical kind of color realism is reductive: the color properties are identified with properties specified in other terms (as ways of altering light, for instance). If no reductive analysis is available — if the colors are primitive sui generis properties — this is often taken to be a convincing argument for eliminativism. That is, realist primitivism is usually thought to be untenable. The realist preference for reductive theories of color over the last few decades is particularly striking in light (...) of the generally anti-reductionist mood of recent philosophy of mind. The parallels between the mind—body problem and the case of color are substantial enough that the difference in trajectory is surprising. While dualism and non-reductive physicalism are staples, realist primitivism is by and large a recent addition to the color literature. And it remains a minority position, although one that is perhaps gaining support. In this paper, we investigate whether it should be accepted, and conclude it should not be. (shrink)
