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.

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.

Without looking beyond the conditions under which laying hens typically live in the contemporary U.S. egg industry, we can understand why the production and consumption of factory farmed eggs could be judged immoral. However, the question, What (if anything) is wrong with animal by-products? cannot always be adequately answered by looking at the conditions under which animals live out their productive lives. For the dairy industry looks benign in those terms, but if we look beyond the conditions under which milk (...) cows live, we can better understand some animal rights activists' reasons for objecting to dairy products. The contemporary U.S. dairy industry requires a slaughter industry between one-seventh and one-third the size of the contemporary beef industry. Today, beef slaughter is vastly more humane than poultry slaughter, but if today's beef slaughter industry is judged emmoral, the contemporary dairy industry should be judged similarly immoral, because the two are wedded. This is the deep reason for moral suspicion of the dairy industry. (shrink)

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.

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.

Why should governments or individuals invest time and resources in conserving biodiversity? A popular answer is that biodiversity has both instrumental value for humans and intrinsic value in its own right. Defending Biodiversity critically evaluates familiar arguments for these claims and finds that, at best, they provide good reasons for conserving particular species or regions. However, they fail to provide a strong justification for conserving biodiversity per se. Hence, either environmentalists must develop more compelling arguments for conserving biodiversity or else (...) they should modify their agenda. This short precis is an overview of the central findings of our book. (shrink)

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)

In his recent article Should Trees Have Standing? Revisited" Christopher D. Stone has effectively withdrawn his proposal that natural objects be granted legal rights, in response to criticism from the Feinberg/McCloskey camp. Stone now favors a weaker proposal that natural objects be granted what he calls legal "considerateness". I argue that Stone's retreat is both unnecessary and undesirable. I develop the notion of a "de facto" legal right and argue that species already have de facto legal rights as statutory beneficiaries (...) of the "Endangered Species Act of 1973." I conclude that granting certain nonhuman natural entities legal rights is both more important and less costly that Stone and his critics have realized, and that it is not Stone's original proposal which needs rethinking, but the concept of interests at work in the Feinberg/McCloskey position.

As arti® cial intelligence moves ever closer to the goal of producing fully autonomous agents, the question of how to design and implement an arti® cial moral agent (AMA) becomes increasingly pressing. Robots possessing autonomous capacities to do things that are useful to humans will also have the capacity to do things that are harmful to humans and other sentient beings. Theoretical challenges to developing arti® cial moral agents result both from controversies among ethicists about moral theory itself, and from (...) computational limits to the implementation of such theories. In this paper the ethical disputes are surveyed, the possibility of a `moral Turing Test ’ is considered and the computational di culties accompanying the diŒerent types of approach are assessed. Human-like performance, which is prone to include immoral actions, may not be acceptable in machines, but moral perfection may be computationally unattainable. The risks posed by autonomous machines ignorantly or deliberately harming people and other sentient beings are great. The development of machines with enough intelligence to assess the eŒects of their actions on sentient beings and act accordingly may ultimately be the most important task faced by the designers of arti® cially intelligent automata.

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.

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.

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.

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.

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.

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)

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)

This volume presents readings in philosophy from around the world and across history, from the Buddha to bell hooks, organized around traditional Anglo-European philosophical themes such as freedom and the existence of God. An introductory section discusses the nature of philosophy and gives advice on reading philosophical texts, and introductions to selections provide background and questions for thought.

Nanotechnology is the latest in a growing list of emerging technologies that includes nuclear technologies, genetics, reproductive biology, biotechnology, information technology, robotics, communication technologies, surveillance technologies, synthetic biology, and neuroscience. As was the case for many of the technologies that came before, a key question facing nanotechnology is what type of regulatory oversight is appropriate for this emerging technology. As two of us wrote several years ago, the question facing nanotechnology is not whether it will be regulated, but when and (...) how.Yet, appropriate regulation of nanotechnology will be challenging. The term “nanotechnology” incorporates a broad, diverse range of materials, technologies, and products, with an even greater spectrum of potential risks and benefits. This technology slashes across the jurisdiction of many existing regulatory statutes and regulatory agencies, and does so across the globe. Nanotechnology is developing at an enormously rapid rate, perhaps surpassing the capability of any potential regulatory framework to keep pace. Finally, the risks of nanotechnology remain largely unknown, both because of the multitude of variations in the technology and because of the limited applicability of traditional toxicological approaches such as structure-activity relationship to nanotechnology products.

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)

Previous research has demonstrated electroencephalogram (EEG) changes in response to low-odor concentrations, resulting in near-chance detection. Such findings have been taken as evidence for olfaction without awareness. We replicated and extended previous work by examining EEG responses to water-water control, 0.0001, 0.001, 0.01, and 1 ppm isoamyl acetate (IAA) in water paired with water only. Detection was above chance (>50%) for .001 and above, and alpha decreased only to those concentrations, suggesting that EEG changes corresponded to IAA awareness. However, when (...) correct trial EEGs were compared to incorrect trial EEGs during .001 ppm, right posterior/central alpha decreased during incorrect trials and alpha decreased more globally (including frontal sites) during correct trials. These data may not reflect awareness or unawareness per se. Instead, results are discussed regarding activation of perceptual systems in the posterior region during incorrect trials and the activation of frontal action systems during a subset of correct trials.

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.

The situational context within which an activity takes place, as well as the personality characteristics of individuals shape the types of strategies people choose in order to regulate their emotions, especially when confronted with challenging or undesirable situations. Taking self-regulation as the framework to study emotions in relation to learning and performing chamber music canon repertoire, this quasi-experimental and intra-individual study focused on the self-rated emotional states of a professional classical cellist during long-term sustained practice across 100-weeks. This helped to (...) develop greater awareness of different emotions and how they vary over artistic events (9 profiled concerts and 1 commercially recorded album). Data analysis included traditional psychometric measurements to test the internal consistency of the time series data as well as the relationship between variables (artistic events). The study mapped the cellist’s flexible regulation of 17 different positive and negative emotions empirically linked to learning and achievement while practicing within the social context of performing music publicly at a high level. Findings arising from the study help with understandings of how to support musicians to maximize their artistic potential by reducing emotion dysregulation and strengthening the types of adaptive methods that enable them to manage their own emotions.

In his publications since the three-volume Spheres project, Peter Sloterdijk thematizes religion as a now outmoded immunological system. He says it can no longer perform its historical function because humans have lost the protection of a world periphery. The entirety of what was “outside” is now “inside,” and this has happened because: (1) spheres are systems, and as Luhmann shows, systems naturally complexify and expand themselves by becoming self-reflective; and (2), as Nietzsche says, humans are driven by a need to (...) surpass themselves. The loss of world periphery is manifest in the climate crisis, which registers as a general sense that we must “change our lives.” This gives Sloterdijk the chance (or so I argue) to create a new sphere (in the symbolic mode) that can be shared by all humans, a function no so-called world religion can fulfill. This new solidarity would come about when the earth becomes the completing “other” to every self, and individuals act in accordance with the imperative to assure the existence of human life on earth. The last section of the paper contrasts Sloterdijk’s spherology with Latour’s actor–network theory, and his later move into political ecology. I argue that, despite their alliance against “globalism,” Latour and Sloterdijk are working with very different models of space (spheres vs. networks) and have different agendas vis-à-vis the climate crisis. Sloterdijk is trying to build ethical solidarity among humans, while Latour is concerned with a politics (in the Schmittian sense) between both human and nonhuman actors, including Gaia, which is both the space of action (a network of networks) and an actor in its own right. And finally, I take up Sloterdijk’s statement that religions were never anything other than human practices, compared with Latour’s call for acting “religiously,” which means “respecting what others cling to.” I do this by way of showing there are conceptual limitations to the concept of spheres and to Sloterdijk’s project overall.

The qigong state of bigu is believed to be supported by the absorption of qi from the universe. Gamma radiation is ubiquitous in the cosmos and, according to some, may be a possible source of energy for cellular functioning. When the concept of energy is integrated with the concept of dynamical systems, the logic leads to the theory—termed systemic memory—that predicts all systems, from the micro to macro, store information and energy to various degrees. New research indicates that the human (...) body absorbs gamma radiation from the environment and emits high-frequency X rays. There are substantial individual differences in these effects that appear to be related, in part, to the psychological state of the person. Future research can determine if bigu is associated with increased absorption of gamma radiation and/or decreased emission of high frequency X rays. The hypothesis that qi can be viewed as quality information is proposed. (shrink)

In perception science, an alternative to focusing on individual sensory systems is to describe the environment to be perceived. We focus on the emergent dynamics of human-environment interactions as an important category of the environment to be perceived. We argue that information about such dynamics is available in subtle patterns of movement variability that, of necessity, stimulate multiple sensory systems.
