The standard means of seeking the classical limit in Bohmian mechanics is through the imposition of vanishing quantum force and quantum potential for pure states. We argue that this approach fails, and that the Bohmian classical limit can be realized only by combining narrow wave packets, mixed states, and environmental decoherence.

Albert Einstein deliberately and repeatedly expressed his general religious views. But what were his views of mysticism? His statements on the subject were few, relatively obscure, and often misunderstood. A coherent answer requires setting those statements in historical, cultural, and theological context, as well as examining Einstein's philosophical and religious views. Though the Einstein that emerges clearly rejected supernatural mysticism, his views of “essential” mysticism were—though largely implicit—more nuanced, more subtle, and ultimately more sympathetic than “mere appearance” suggests.

Risk management of nanotechnology is challenged by the enormous uncertainties about the risks, benefits, properties, and future direction of nanotechnology applications. Because of these uncertainties, traditional risk management principles such as acceptable risk, cost–benefit analysis, and feasibility are unworkable, as is the newest risk management principle, the precautionary principle. Yet, simply waiting for these uncertainties to be resolved before undertaking risk management efforts would not be prudent, in part because of the growing public concerns about nanotechnology driven by risk perception (...) heuristics such as affect and availability. A more reflexive, incremental, and cooperative risk management approach is required, which not only will help manage emerging risks from nanotechnology applications, but will also create a new risk management model for managing future emerging technologies.

Medical technologies, including nanomedicine products, are intended to improve health but in many cases may also create their own health risks. Medical products that create their own health risks differ from most other risk-creating technologies in that the very purpose of the medical technology is to prevent or treat health risks. This paradox of technologies intended to reduce existing risks that may have the effect of creating new risks has two conflicting implications. On one hand, we may be more tolerant (...) of health risks from medical technologies because these products are intended to, and often do, reduce overall health risks and improve our health. The health benefits of a medical technology may outweigh the unavoidable adverse effects of that same technology in an individual patient or in the overall treated population. (shrink)

In his recent essay on moral pluralism in environmental ethics, J. Baird Callicott exaggerates the advantages of monism, ignoring the environmentally unsound implications of Leopold’s holism. In addition, he fails to see that Leopold’s view requires the same kind of intellectual schitzophrenia for which he criticizes the version of moral pluralism advocated by Christopher D. Stone in Earth and Other Ethics. If itis plausible to say that holistic entities like ecosystems are directly morally considerable-and that is a very big if-it (...) must be for a very different reason than is usually given for saying that individual human beings are directly morally considerable.

E-Z Reader 7 is a processing model of eye-movement control. One constraint imposed on the model is that high-level cognitive processes do not influence eye movements unless normal reading processes are disturbed. I suggest that this constraint is unnecessary, and that the model provides a sensible architecture for explaining how both low- and high-level processes influence eye movements.

Laboratory studies find a strategic component to moral behaviour that differs in significant ways from common perceptions of how morality works. Models based on a preference for relative payoffs offer an explanation.

Those who conduct research on animals and those who advocate on behalf of animals have more in common than is generally supposed. A more nuanced understanding of the arguments defending animals' interests can help replace the current politics of confrontation with a genuine conversation.

Essays examine various sides of medical ethics issues such as euthanasia, organ transplants, and living wills.

Drawing heavily on recent empirical research to update R.M. Hare's two-level utilitarianism and expand Hare's treatment of "intuitive level rules," Gary Varner considers in detail the theory's application to animals while arguing that Hare should have recognized a hierarchy of persons, near-persons, & the merely sentient.

In Use and Abuse Revisited: Response to Pluhar and Varner, Kathryn Paxton George misunderstands the point of my essay, In Defense of the Vegan Ideal: Rhetoric and Bias in the Nutrition Literature. I did not claim that the nutrition literature unambiguously confirms that vegans are not at significantly greater risk of deficiencies than omnivores. Rather than settling any empirical controversy, my aim was to show how the literature can give the casual reader a skewed impression of what is known about (...) the risks of a vegan diet. In this brief rejoinder, I illustrate how two essays by nutritionists in the same volume as George's and my essays, and a referee's report on my manuscript which was authored by a nutritionist, confirm the soundness of this basic insight.

Standard economic theory does not capture trust among anonymous Internet traders. But when traders are allowed to have social preferences, uncertainty about a seller’s morals opens t he door for trust, reward, exploitation and reputation building. We report experiments suggesting that sellers’ intrinsic motivations to be trustworthy are not sufficient to sustain trade when not complemented by a feedback system. We demonstrate that it is the interaction of social preferences and cleverly designed reputation mechanisms that solves to a large extent (...) the trust problem on Internet market platforms. However, economic theory and social preference models tend to underestimate the difficulties of promoting trust in anonymous online trading communities. (shrink)

Charles S. Peirce sketches "a nest of three arguments for the Reality of God" in his article "A Neglected Argument for the Reality of God." I provide careful analysis and explication of Peirce's argument, along with consideration of some objections. I argue that there are significant differences between Peirce's neglected argument and the traditional arguments for God's existence; Peirce's analysis of the neglected argument into three arguments is misleading; there are two distinct levels of argument that Peirce does not recognize; (...) and it is doubtful whether the argument meets all the criteria set by Peirce himself.

Environmentalists are sometimes criticized for implausibly separating human beings from nature. However, in the debate between the "wise-use" and environmental movements, it is the proponents of "wise-use," and not the environmentalists, who implausibly divide human beings from nature. The "wise-use" movement calls for landowners to be compensated whenever environmental regulations reduce the economic value of their land. However, a well-established principle of constitutional law is that compensation is not required if the regulations prevent harm to others. Insofar as they can (...) plausibly be construed as preventing harm to others, then, environmental regulations can be enforced without running afoul of the just compensation clause of the Fifth Amendment. I argue that while the public trust doctrine of U.S. common law can be extended to cover ecological processes on which the long-term wellbeing of the nation and its people depend, environmentalists must do a better job of articulating how this is so. In doing so, however, they will show that the wise use movement's position depends on an implausible separation of humans from the eco-systems on which we depend. (shrink)

William James’s historic fascination with psychic phenomena, including the possibility of life after death, has become more widely known with the publication of recent books and articles on this controversial aspect of his scientific legacy. However, little is known about the emerging evidence suggesting the possibility that James’s scientific interest in these topics has not waned since he died. This paper reviews preliminary observations, including two exploratory double-blinded mediumship investigations, which are consistent with the hypothesis that James (with others) may (...) be continuing his lifelong quest to address the question of the survival of consciousness after physical death ‘from the other side’. These proof-of-concept investigations illustrate how future systematic laboratory research is possible. The limitations of current neuroscience methods are explicated in terms of investigating the hypothesis of the brain as a possible antenna-receiver for consciousness. If James’s tentative conclusions about the nature of the relationship between consciousness and the brain turn out to be accurate, then it is logically plausible (if not essential) to posit the possibility that his efforts have persisted in the recent past and present, and may even continue in the future. Scientific integrity plus the pursuit of verity require our being open to this important theoretical and empirical possibility. (shrink)

SummaryIn this essay I critically discuss the views of Thomas Kuhn and Paul Feyerabend on the succession of scientific theories. I argue that, if Karl Popper's desiderata for theory succession are properly explicated, they constitute a basis for refuting the “incommensurability“ thesis of Kuhn and Feyerabend. Popper's claim that a new theory must constitute an “improvement” over the old implies that the new theory must be able to be interpreted as referring to most of the phenomena as its predecessor.RésuméDans cet (...) essai, je discute les vues de Thomas Kuhn et de Paul Feyerabend sur la succession des théories scientifiques. Je montre que si les desiderata de Karl Popper pour la succession des théories sont correctement explicités, ils constituent une base pour réfuter la thèse ?incommen‐surabilité de Kuhn et de Feyerabend. Ľexigence de Popper selon laquelle une nouvelle théorie doit améliorer la précédente implique que la nouvelle théorie doit pouvoir être interprétée comme se référant à une plus grande part des phénoménes que ses prédécesseurs.ZusammenfassungIn der vorliegenden Arbeit werden Thomas Kuhns und Paul Feyerabends Auffassungen über die Frage, wie wissenschaftliche Theorien sich ablösen und folgen, erörtert.

Proppers Forderung, dass eine neue Theorie gegenüber der alten eine Verbesserung darstellen müsse, impliziert, dass die neue Theorie so interpretiert werden kann, dass sie sich auf die meisten Phänomene bezieht, von denen auch in der Vorgängerin die Rede war.

In this essay it will be argued that if preferential treatment for individuals who have suffered from past discrimination is permissible in any context, it should be extended to the allocation of scarce medical resources. This contention will be based on two facts: one, that health care, in particular certain life-saving operations, constitutes a scarce social good similar to but more important than other social goods such as desirable jobs and positions in desirable professional schools; secondly, that a claim can (...) plausibly be made that the greater incidence of death due to heart disease among blacks is a result of the effect of past discrimination. In addition, an argument to the effect that preferential treatment is indeed permissible will be sketched that is based upon a critique of the decision in the Bakke case. (shrink)

Edmund Husserl's historical importance is marked by a curious conjunction. He is easily among the most influential philosophers of the twentieth century and yet no one has taken up his view. The first of these has received a monumental amount of consideration, the second virtually none. But the second, in its own way, is at least equally remarkable. In this essay I will consider why his view of philosophy found no subscribers and what we might make of this legacy of (...) failure. (shrink)

There is much we do not know about nanotechnology. Despite its tremendous promise, nanotechnology today is mostly forecast and fervent hope. Predictions that spending on nanotechnology will increase from current levels of $13 billion to more than $1 trillion by 2015 are no more than that – simply predictions. Hopes that nanotechnology will be an essential part of solving the globe's energy, food, and water problems should be tempered by recalling a century of revolutionary technologies that failed to live up (...) to their early promise such as nuclear energy, supersonic airplanes, or gene therapy. Many other questions continue to nip at nanotechnology's heels, not the least of which are debates about what is and is not technically feasible. Despite these uncertainties, we can have complete confidence in one aspect of nanotechnology's future – it will be subject to a host of regulations. (shrink)

The purpose of this article is to provide one prominent perspective from the research literature on a conception of feedback in educational psychology as proposed by John Hattie and colleagues, and to then adapt these concepts to develop a framework that can be applied in music performance teaching at a variety of levels. The article confronts what we see as a lack of understanding about the importance of this topic in music education and provides suggestions that will help music teachers (...) refocus how they use feedback within their teaching. Throughout the article, we draw heavily on the work of John Hattie and his colleagues whose explanations on all facets of feedback, but especially those forms of feedback that are focused on ensuring students understand “where to next”—have had a huge impact on school education through various publications.

No one need deny the importance of language to thought and cognition. At the same time, there is a tendency in studies of mind and mental functioning to assume that properties and principles of linguistic, or language-like, forms of representation must hold of forms of thought and representation in general. Consideration of a wider range of symbol systems shows that this is not so. In turn, various claims and arguments in cognitive theory that depend on assumptions applicable only to linguistic (...) systems, do not go through or become difficult to state in a manner that makes them both interesting and plausible.

Subjects and Simulations presents essays focused on suffering and sublimity, representation and subjectivity, and the relation of truth and appearance through engagement with the legacies of Jean Baudrillard and Philippe Lacoue-Labarthe.

Scientific research is subject to a number of regulations which impose incidental (time, place), rather than substantive (type of research), restrictions on scientific research and the knowledge created through such research. In recent years, however, the premise that scientific research and knowledge should be free from substantive regulation has increasingly been called into question. Some have suggested that the law should be used as a tool to substantively restrict research which is dual-use in nature or which raises moral objections. There (...) are, however, some problems with using law to restrict or prohibit certain types of scientific research, including (i) the inherent imprecision of law for regulating complex and rapidly evolving scientific research; (ii) the difficulties of enforcing legal restrictions on an activity that is international in scope; (iii) the limited predictability of the consequences of restricting specific branches of scientific research; (iv) inertia in the legislative process; and (v) the susceptibility of legislators and regulators to inappropriate factors and influence. Rather than using law to restrict scientific research, it may be more appropriate and effective to use a combination of non-traditional legal tools including norms, codes of conduct, restrictions on publication, and scientist-developed voluntary standards to regulate problematic scientific research.
