Through socio-cultural analysis of the discourse of bullying, the present article aims to show that moral learning is less about teaching children the difference between right and wrong and more about making available to them what Tappan and Wertsch describe as the mediational means to engage in their own moral learning. Bullying is explained in Bakhtinian terms as a form of ?authoritative discourse?. Both moral education and manipulative adolescent bullying are presented as, in a broad sense, forms of political practice. (...) The same 13-year-old girl was recorded as she talked with peer ?counsellors? about her own bullying and then a fortnight later in the course of directing and featuring in a tutor-group video which aimed to introduce younger pupils to their new school. Through the inter-animation of social voices, new moral ideas are appropriated by the participants. In a succession of ?zones of proximal development?, students support and ?scaffold? each other?s thinking in their progression towards changed levels of moral awareness. (shrink)

Abstract Critics of The Agrarian Vision: Sustainability and Environmental Ethics (Lexington: 2010, University Press of Kentucky) have difficulties with its commitment to agrarian philosophy, and have also suggested that the program described there needs more elaboration of how sustainability might be pursued, especially in its social dimensions. The book draws upon agrarian philosophy to argue that habit and material practice are an appropriate and vital focus of ethics. Attention to habit and material practice will counterbalance an overemphasis on intentions and (...) outcomes in contemporary environmental philosophy. It is in this sense that agrarianism contributes to an ethic of sustainability by showing how contemporary food practices—the culture of the table—might contribute to an enabling sense of community solidarity. The book does not advocate a return to once vibrant agrarian traditions. Content Type Journal Article Category Articles Pages 1-10 DOI 10.1007/s10806-011-9329-z Authors Paul B.

Though the term “commodification” is used broadly, a theory of the processes by which goods become exchangeable and in fact objects of monetized exchange reveals a key site for technological politics. Commodities are goods that are alienable, somewhat rival, generally with low exclusion costs, and that are often consumed in use. Technological advances can affect all of these traits for certain goods, effectively bringing about a process of commodification by technological means. However, in order to function with specific contexts, technologies (...) are designed and manufactured according to technical standards, standards that in turn take on features of what David Grewal ( 2008 ) has called “network power.” As such, standard setting processes become the potential locus for political argument over the legitimacy of a commodification process. Theorists hoping to develop more democratic theories of technological governance should thus recognize the significance of standards and the role they play in either promoting or controlling social relations organized according to the norms of monetized exchange.

Recent developments in synthetic biology are described and characterized as moving the era of biotechnology into platform technologies. Platform technologies enable rapid and diffuse innovations and simultaneous product development in diffuse markets, often targeting sectors of the economy that have traditionally been thought to have little relationship to one another. In the case of synthetic biology, pharmaceutical and biofuel product development are occurring interactively. But the regulatory and ethical issues associated with these two applications share very little overlap. As such, (...) there is some risk that focus on traditional medical applications, for which the ethical expertise is highly developed, will overshadow the ethical issues that arise in connection with land use and its attendant socioeconomic consequences, especially in the developing world. The 2010 report of the Presidential Commission for the Study of Bioethics exhibits this tendency. (shrink)
An environmental, climate mitigation rationale for research and development (R&D) on liquid transportation fuels derived from plants emerged among many scientists and engineers during the last decade. However, between 2006 and 2010, this climate ethic for pursuing biofuel became politically entangled and conceptually confused with rationales for encouraging greater use of plant-based ethanol that were both unconnected to climate ethics and potentially in conflict with the value-commitments providing a mitigation-oriented reason to promote and develop new and expanded sources of biofuel. (...) I argue that the conceptual construct of technological trajectories provides a fecund approach to the ethical evaluation of R&D strategies in the case of plant-based liquid transportation fuels. The idea of a trajectory has a current use in the literature of science studies and aptly summarizes a number of themes that are critical to the evaluation of tools and techniques whose future shape, design, applications and potential consequences are necessarily somewhat speculative. In the case of biofuels, it is the imagined future trajectory that provides the basis for resistance to an emerging technology, rather than the present-day technical capabilities and the unexpected consequences of biofuel development.

Abstract What is the significance of the wicked problems framework for environmental philosophy? In response to wicked problems, environmental scientists are starting to welcome the participation of social scientists, humanists, and the creative arts. We argue that the need for interdisciplinary approaches to wicked problems opens up a number of tasks that environmental philosophers have every right to undertake. The first task is for philosophers to explore new and promising ways of initiating philosophical research through conducting collaborative learning processes on (...) environmental issues. The second task is for philosophers to recognize the value of philosophical skills in their engagements with members of other disciplines and walks of life in addressing wicked problems. The wicked problems framework should be seen as an important guide for facilitating philosophical research that is of relevance to problems like climate change and sustainable agriculture.

Abstract: This essay critically examines whether there are ethical dimensions to the way that expertise, knowledge claims, and expressions of skepticism intersect on technical matters that influence public policy, especially during times of crisis. It compares two different perspectives on the matter: a philosophical outlook rooted in discourse and virtue ethics and a sociological outlook rooted in the so-called third-wave approach to science studies. The comparison occurs through metaphilosophical analysis and applied claims that clarify how the disciplinary orientations appear to (...) lead to different judgments about matters related to Robert Paarlberg's condemnation of activists who advise African politicians to ban genetically modified food.

Recent publications by Pogge ( Global ethics: seminal essays. St. Paul: Paragon House 2008 ) and by Singer ( The life you can save: acting now to end world poverty. New York: Random House 2009 ) have resuscitated a debate over the justifiability of famine relief between Singer and ecologist Garrett Hardin in the 1970s. Yet that debate concluded with a general recognition that (a) general considerations of development ethics presented more compelling ethical problems than famine relief; and (b) some (...) form of development would be essential to avoiding the problems of growth noted by Hardin. Better than renewing the debate, we should recognize two points. First, food needs do indeed evoke a moral response that is more direct and compelling than the philosophical positions often generated to rationalize a duty to bring aid. As such the argument for feeding hungry people cannot be generalized into a paradigm for development ethics without distortions that undercut the morally valid elements in Singer’s original argument. Second, contrary to prevailing assumptions in present day development ethics, food aid and famine relief continue to be important priorities for international agencies, notably the World Food Program. Emergency food assistance, the nominal topic of Singer’s original article, thus is an important issue for agricultural as well as development ethics, though one that should indeed be seen as distinct from more complex duties to address the conditions of chronic poverty and underdevelopment.

Agrarian political philosophies since ancient Greece stress the role of agriculture in forming political solidarity and civic virtue. More recent transformations suggest a way to conjoin these elements of what makes a polity politically sustainable with environmental sensitivity and literacy.
Mainstream environmental ethics grew out of an approach to value that was rooted in a particular conception of rationality and rational choice. As weaknesses in this approach have become more evident, environmental philosophers have experimented with both virtue ethics and with pragmatism as alternative starting points for developing a more truly ecological orientation to environmental philosophy. However, it is possible to see both virtue ethics and pragmatism as emerging from older philosophical traditions that are here characterized as “agrarian.” Agrarian philosophy (...) stresses the role of nature, soil and climate in the formation of moral character as well as social and political institutions. As such, reaching back to the agrarian tradition may provide a way to move forward with both virtue oriented themes as well as pragmatist themes in developing ecological ethics. (shrink)
A noticeable push toward using agricultural crops for ethanol production and for undertaking research to expand the range of possible biofuels began to dominate discussions of agricultural science and policy in the United States around 2005. This paper proposes two complementary philosophical approaches to examining the philosophical questions that should be posed in connection with this turn of events. One stresses a critique of underlying epistemological commitments in the scientific models being developed to determine the feasibility of various biofuels proposals. (...) The second begins with a broader set of questions about the philosophical goals of agriculture, then queries the place that a turn to biofuels might have within the philosophy of agriculture. Both are portrayed as viable and important. The paper itself is a preliminary stage-setting reflection on the need for these two types of philosophical inquiry. (shrink)
Nanotechnologies that have been linked to the possibility of enhancing cognitive capabilities of human beings might also be deployed to reduce or eliminate such capabilities in non-human vertebrate animals. A surprisingly large literature on the ethics of such disenhancement has been developed in response to the suggestion that it would be an ethically defensible response to animal suffering both in medical experimentation and in industrial livestock production. However, review of this literature illustrates the difficulty of formulating a coherent ethical debate. (...) Well structured arguments for disenhancement can be made on the basis of mainstream views on the basis of ethical obligations to animals, but these arguments have not been persuasive against the moral intuition that disenhancements are unethical. At the same time, attempts to ground these intuitions in a coherent philosophical doctrine have been plagued by logical fallacies and question begging assertions. As such, the debate over animal disenhancement forecasts an enduring conundrum with respect to the core question of transforming the nature of sentient beings, and this conundrum is logically independent of claims that relate either to the distinctive of human beings or to issues deriving from the emphasis on enhancement.

Formal, informal and material institutions constitute the framework for human interaction and communicative practice. Three ideas from institutional theory are particularly relevant to technical change. Exclusion cost refers to the effort that must be expended to prevent others from usurping or interfering in one’s use or disposal of a given good or resource. Alienability refers to the ability to tangibly extricate a good or resource from one setting, making it available for exchange relations. Rivalry refers to the degree and character (...) of compatibility in various uses for goods. The paper closes with a note on how attention to these factors might be useful ways toconceptualize what Langdon Winner has called “the technological constitution of society,” and what Andrew Feenberg has theorized as “secondary rationalization,” as well as within more practical contexts of technical research, development and design.

Universities are facing a critical challenge; university citizenship has steadily declined over the last few decades. As a self-governing entity, most of the foundational elements of a university community are within its own control. As a result, the health and future welfare of the institution depends greatly on the quality of its leaders and robustness of its governing structure. These in turn depend on the quality of those undertaking leadership roles and serving on governing bodies and on the degree to (...) which they reflect its values and aspirations. Maximising the probability that these desiderata will be achieved requires a broad-based faculty willingness to serve conscientiously on these bodies and to serve as administrators to be involved in selecting members, and to be involved on the myriad of sub-committees, task forces, departmental committees, and the like. It is not only an abdication of citizenship to leave governance and administration of the institution to a few willing faculty, it is dangerous and puts at risk the welfare of the institution. Even if these few were all able to place the welfare of the institution above their own particular agendas and their self-interest (not something on which to count), the process of self-selection could not be expected to result in a group that would adequately reflect, represent or understand the breadth and depth of the needs, aspirations and complex circumstances of the entire institution. The larger the pool of willing participants, the greater the probability that those selected will reflect best the institutional diversity. This paper draws out the rights and obligations of faculty citizens embedded in the structural arrangements common to universities in the western world. In part A we examine three fundamental components of those arrangements, components that collectively define certain rights and entail certain obligations of citizenship. These obligations flow in part from essential rights, and also in part from what is necessary to sustain the viability and vibrancy of the community. In Part B, we examine some of these essential obligations of citizenship. In Part C, we make recommendations about how to promote effective citizenship; these recommendations are collected after Part C under the heading “Recommendations.”. (shrink)
Holism and emergence are coherent notions. The paper points to the classes of emergent phenomena -- such as autocatalysis -- that are taken as commonplace phenomena in biological sciences. Thus it questions the Democritean credo, “wholes are completely determined by their parts” (in some of its forms, called mereological determinism), that has become a dogma of contemporary philosophy. A living thing requires the ability to initiate, mediate and terminate processes that produce products that make up the whole. Autocatalysis is one (...) such mechanism, and its action at the level of the whole produces effects on the parts such that the properties, manifested by the parts in the absence of the whole engaged in autocatalysis, are altered. For these reasons, some writers suggest that autocatalysis is a law of organization and that it is emergent. It also appears that this is a case of downward causation -- one that clearly occurs in nature. If this is not a case of downward causation on Kim’s terms, then biological systems that are claimed to be emergent do not need to involve downward causation in his sense. The author thinks that this constitutes downward causation in an important sense -- the causal properties of the whole drive the behavior of the parts. Another set of examples comes from chaos dynamics. Relying on this evidence, the author challenges the Democritean credo (and mereological determinism) and shifts the onus of proof. (shrink)
I will argue that one class of issues in computer ethics oftenassociated with privacy and a putative right to privacy isbest-analyzed in terms that make no substantive reference toprivacy at all. These issues concern the way that networkedinformation technology creates new ways in which conventionalrights to personal security can be threatened. However onechooses to analyze rights, rights to secure person and propertywill be among the most basic, the least controversial, and themost universally recognized. A risk-based approach to theseissues provides a (...) clearer statement of what is ethicallyimportant, as well as what is ethically problematic. Once theissues of security have been articulated clearly, it becomespossible to make out genuine issues of privacy in contrast tothem. (shrink)
Debates over the future of agriculture in North Americaestablish a dialectical opposition between conventional,industrial agriculture and alternative, sustainable agriculture.This opposition has roots that extend back to the 18th century inthe United States, but the debate has taken a number ofsurprising turns in the 20th century. Originally articulated as aphilosophy of the left, industrial agriculture has utilitarianmoral foundations. In the US and Canada, the articulation of analternative to industrial agriculture has drawn upon threecentral themes: the belief that agriculture is, in some (...) way, tiedto democracy; the belief that complex bureaucratic organizationsare inherently opposed to human interests; and the belief thatthe family farms characteristic of 19th century North Americatend to produce people of superior moral character. It has proveddifficult to weave these themes into a coherent vision ofagriculture for the 21st century. Often, risk and health-basedconcerns are the basis for public criticism of conventionalagriculture, but these do not conflict with the utilitarianorientation of the industrial model, and are easily incorporatedinto it. If there is to be a philosophical debate over the futureof agriculture, we must find some way to rehabilitate thequasi-Aristotelean view of agriculture that emerges from thethree critical themes noted above.

The essays in this volume critically analyze and revitalize agrarian philosophy by tracing its evolution in the classical American philosophy of key figures such as Franklin, Jefferson, Emerson, Thoreau, Dewey, and Royce.
The development of modern evolutionary ethics began shortly after the publication of Charles Darwin's On the Origin of Species by Natural Selection. Early discussions were plagued by several problems. First, evolutionary ethical explanations were dependent on group-selection accounts of social behavior (especially the explanation of altruism). Second, they seem to violate the philosophical principle that “ought” statements cannot be derived from “is” statements alone (values cannot be derivedfrom facts alone). Third, evolutionary ethics appeared to be biologically deterministic, deemed incompatible with (...) the free will required for ethics to be possible. Fourth, social policies based on evolutionary theory (for example, eugenics in the early part of this century) seemed patently unethical. Sociobiology (which coalesced as a field of study with Edward O. Wilson's Sociobiology: The New Synthesis, 1975) addressed several of these problems and provided a rich framework and a new impetus for evolutionary ethics. The lingering problems were the philosophical is-ought barrier and biological determinism. After tracing the early and more recent development of evolutionary ethics, I argue that the remaining problems can be surmounted and an incipient evolutionary ethics can be defended. Thoroughgoing evolutionaryethics must await theoretical developments in neurobiology and cognitive science. (shrink)
Although cloning may eventually become an important technology for livestock production, four ethical issues must be addressed before the practice becomes widespread. First, researchers must establish that the procedure is not detrimental to the health or well-being of affected animals. Second, animal research institutions should evaluate the net social benefits to livestock producers by weighing the benefits to producers against the opportunity cost of research capacity lost to biomedical projects. Third, scientists should consider the indirect effects of cloning research on (...) the larger ethical issues surrounding human cloning. Finally, the market structure for products of cloned animals should protect individual choice, and should recognize that many individuals find the prospect of cloning (or consuming cloned animals) repugnant. Analysis of these four issues is complicated by spurious arguments alleging that cloning will have a negative impact on environment and genetic diversity. (shrink)
Risk communication poses a challenge to ordinary norms of truth-telling because it can easily mislead. Analyzing this challenge in terms of a systematic divergence between expertise and public attitudes fails to recognize how two specific features of the concept of risk play a role in managing daily affairs. First, evaluating risk always incorporates an estimate of the reliability of information. Since risk communication is an effort at providing information, audiences will naturally and appropriately incorporate their assessment of the reliability of (...) the risk communicator into their assessment of the risk as such. Second, one conceptual and grammatical feature of the concept of risk is to categorize experience as non-routine and demanding further deliberation. That is, the whole point of calling something a risk can be to distinguish it from activities or phenomena that need no further attention. Risk communications that stress relative comparisons of measured probabilities and expected utilities can be inconsistent with both features of our concept of risk. At best they mislead; at worst they undermine our society’s capacity to cope with risk. While there are no simple answers to these two conundrums, technical experts should bear them in mind when communicating with the broader public. (shrink)
Biotechnology applied to traditional foodanimals raises ethical issues in three distinctcategories. First are a series of issues that arise inthe transformation of pigs, sheep, cattle and otherdomesticated farm animals for purposes that deviatesubstantially from food production, including forxenotransplantation or production of pharmaceuticals.Ethical analysis of these issues must draw upon theresources of medical ethics; categorizing them asagricultural biotechnologies is misleading. The secondseries of issues relate to animal welfare. Althoughone can stipulate a number of different philosophicalfoundations for the ethical assessment of welfare,most (...) either converge on Bernard Rollins principle ofwelfare conservation (Rollin, 1995), or devolve intodebates over the ethical significance of animaltelos or species integrity. The principle of welfareconservation prohibits disfunctional geneticengineering of food animals, but would permit alteringanimals biological functions, especially when (as inmaking animals less susceptable to pain or suffering)do so improves an individual animals well being.Objections to precisely this last form of geneticengineering stress telos or species integrity asconstraints on modification of animals, and thisrepresents the third class of ethical issues. Most whohave formulated such arguments have failed to developcoherent positions, but the notion of species being,derived from the 19th century German tradition,presents a promising way to analyze the basis forresisting the transformation of animal natures.

1. Each NABC member institutions should ensure that subject matter on ethical issues associated with food and agricultural biotechnology is systematically integrated into the curriculum of their institution. The pattern of implementation will vary a teach institution, but we expect that some combination of the following three strategies will be employed at most institutions. a) Modules Included in Basic and Applied Science Courses b) Modules Included in General Courses on Applied Ethics c) Special courses on Ethics and Food Biotechnology 2. (...) Each NABC member institution should develop an institutional mechanism for supporting faculty interest and research on ethical issues. Again, implementation will vary. In some institutions, an informal network of interested colleagues will fulfill this function, but in many places an annual workshop or a formal faculty/center will be needed to carry this out.

When scientists consider the interaction of science and value judgments, debates often occur. When public policy grows out of science, disagreements between scientists can become even more spirited. This paper examines the case of nutrition policy in the United States, which has been both at the interface between agriculture and medicine and the object of serious discord concerned with the strength and validity of the scientific evidence and the responsibility for action. The development of indirect intervention policies, designed to (...) educate and inform the public on diet and health, is traced as a practical demonstration of the effects of involvements of nutritional scientists of different disciplines and philosophic bents. Controversies centered mainly on the issues of diet and coronary heart disease and of diet and cancer in nutritional guidelines for Americans and the recommended dietary allowances (RDAs). But the arguments turned on a complex web of values and interests as well as scientific questions. A remarkable turnaround by animal agriculture and its scientific support occurred, changing from a defensive, rightist stance to one that appears to recognize a moral responsibility to the public health. The convincing point was likely the changing market. Nutritional scientists, however, remained divided on the issue of whether a public health strategy keyed to public education should replace a strategy to identify persons of high risk and modify the risk by treatment. Our analysis suggests that the tension between libertarian and utilitarian social values of scientists is at least as important as disagreements relative to validity and strengths of the scientific evidence.

During the last ten years John Beatty, Elisabeth Lloyd and I have argued that the semantic conception of theories is, in the context of biological theorizing, a richer conception of theory structure than the syntactic ("received view") conception. Specifically, I have argued semantic conception of theory structure better represents the structure of evolutionary theory and the relationship of this theory to phenomena. One aspect of the semantic conception that is in need of greater attention is the nature of explanation on (...) this conception. In this paper, I argue that the semantic conception provides a richer mo accurate account of scientific explanation, in particular, of evolutionary explanations. In essence, I argue that explanation involves an appeal to numerous theories in addition to the putative explanatory theory. Employment of these theories is not formally possible in a syntactic conception but is in a semantic conception. (shrink)
Benton Stidd has defended the position that punctuationists are not wrong about the inadequacy of the synthetic theory of evolution for explaining evolution. The thrust of his defense is that arguments to the contrary by Thompson (1983a) involve a rational reconstruction along logical empiricist lines, which is insensitive to historical and social forces in a way that the Kuhnian Weltanschauung view that he espouses is not. I argue in this paper that Stidd has entirely misunderstood my arguments, that the (...) soundness of my arguments does not depend on acceptance of logical empiricism (they are just as sound on a Kuhnian view), and that Stidd fails to establish that punctuated equilibria is a new "paradigm".

Utilitarian ethics provides a model for evaluating moral responsibility in agricultural research decisions according to the balance of costs and benefits accruing to the public at large. Given the traditions and special requirements of agricultural research planning, utilitarian theory is well adapted to serve as a starting point for evaluating these decisions, but utilitarianism has defects that are well documented in the philosophical literature. Criticisms of research decisions in agricultural mechanization and biotechnology correspond to documented defects in utilitarian theory. Research (...) administrators can expect that application of a utilitarian standard ignoring these deficiencies will become the occasion for predictable attacks by critics. Administrators who are sensitive to the strengths and weaknesses of utilitarian ethics are equipped to make a better allocation of research effort. (shrink)
It is frequently argued that home birth is morally irresponsible because it involves the taking of risks on behalf of the fetus. Against this position, I argue three things. First, the fact that home birth involves risks does not necessarily entail that choosing or attending one is morally unacceptable, irresponsible or wrong. Second, parents have a prima facia prerogative to decide on behalf of their fetuses and children whether risks should be taken. While this prima facia prerogative can be overridden, (...) reasonable and widely accepted criteria for doing so are not met in the case of home birth. Third, since the current attitudes and behaviours of physicians with regard to home birth constitute a de facto morally and socially unjustifiable overriding of an informed parental decision, physician autonomy should be restricted so as to preserve the autonomy of the medical consumer.

Flores and Johnson (Ethics 93 No. 3 (1983) pp. 537, 545.) offer a solution to the problem of individual and collective responsibility which obscures the fundamental requirement for responsibility ascriptions, namely, moral agency. Close attention to matters of individual and collective agency provides a simple yet defensible criterion for establishing when an individual is and isn't responsible for the untoward consequences of a collective act.
A large part of environmental policy is based upon scientific studies ofthe likely health, safety, and ecological consequences of human actions and practices. These studies, however, are frequently vulnerable to epistemological and methodological criticisms which challenge their validity. Epistemological criticisms can be used in ethical and political philosophy arguments to challenge the applicability of scientific knowledge to environmental policy, and, in turn, to challenge the democratic basis of specific environmental policies themselves. Uncertainty arguments thus draw upon philosophy of science, epistemology, (...) ethics, and political philosophy to establish conclusions of practical relevance to environmental quality. A theory of how and when uncertainty arguments ought to be given credence in environmental decision making requires an account of how scientific research ought to be integrated into environmental policy generally , plus an account of how public environmental policy is to be set in a democracy.

Many arguments for and against nuclear power can be analyzed according to a matrix of logically competing claims on the need and safety of nuclear power. Logical analysis of the arguments reveals their philosophical basis and contributes to an understanding of their explanatory appeal. The evidential value of claims made in the arguments of both supporters and opponents depends upon familiar issues in the philosophy of language and the philosophy of science.
Several paleontologists have recently challenged the explanatory adequacy of the modern synthetic theory of evolution. Their position is that, contrary to the prevailing view that evolutionary change is gradual, the fossil record manifests long periods of species stasis (equilibrium) punctuated by periods of rapid species formation. And, they argue, this punctuated equilibria pattern challenges the gradualist, adaptationist and extrapolationist assumptions of the modern synthetic theory of evolution and supports a hierarchical, non-extrapolationist (non-reductionist) view of evolution. In this paper I argue (...) that the challenge rests on an inadequate characterization of the modern synthetic theory and that, even accepting punctuated equilibria and an irreducible evolutionary hierarchy, the modern synthetic theory is adequate to explain evolutionary change at all levels of the hierarchy.

In this paper I argue that Bolzano's concept of deducibility and Tarski's concept of logical consequence differ with respect to their philosophical intent. I distinguish between epistemic and ontic approaches to logic, and argue that Bolzano's deducibility presupposes an epistemic approach, while Tarski's logical consequence presupposes an ontic approach.
