This collection of new essays by eleven distinguished environmental philosophers addresses two main questions: first, whether environmental philosophy and ethics should be seen as a form of applied philosophy or as something else, perhaps best called practical philosophy; and second, how environmental philosophy is practiced in human life, especially in the lives of academics.

Environmental holism has been accused of being totalitarian because it subsumes the interests and rights of individuals under the good of the whole biosphere, thus rejecting humanistic ethics. Whether this is true depends on the type of holism in question. Only an extreme form of holism leads to this totalitarian approach, and that type of holism should be rejected, not alone because it leads to unacceptable practices, but because it is too abstract and reductionistic to be an adequate basis for (...) ethics.

Tom Regan criticizes my thesis that obligation toward the environment is grounded in a world view and thereby has a moral overridingness which mere interests and desires do not have. He holds that my approach is too subjectivistic. I counter, first, by explaining that phenomenology, which I use in my analysis of moral obligation, is not subjectivistic in the way emotivism or prescriptivism inethics is subjectivistic. Second, I argue that world views are products of learning and experience of one shared (...) world, that most world views share large areas of agreement, and that they can be argued for and criticized.

This paper will introduce the notion of a naming convention and use this paradigm to both develop a new version of the Second Incompleteness Theorem and to describe when an axiom system can partially evade the Second Incompleteness Theorem.

The dominant language of politics in the United States has been political individualism, with minimal restrictions on property and personal, voluntary conduct. But there are second languages of community that stress cooperation and group action. These second languages include the constitutional tradition for public health. Public health offers a community justification for paternalistic measures that, for example, discourage smoking or require seatbelts.

Let us recall that Raphael Robinson's Arithmetic Q is an axiom system that differs from Peano Arithmetic essentially by containing no Induction axioms [13], [18]. We will generalize the semantic-tableaux version of the Second Incompleteness Theorem almost to the level of System Q. We will prove that there exists a single rather long Π 1 sentence, valid in the standard model of the Natural Numbers and denoted as V, such that if α is any finite consistent extension of Q + (...) V then α will be unable to prove its Semantic Tableaux consistency. The same result will also apply to axiom systems α with infinite cardinality when these infinite-sized axiom systems satisfy a minor additional constraint, called the Conventional Encoding Property. Our formalism will also imply that the semantic-tableaux version of the Second Incompleteness Theorem generalizes for the axiom system IΣ 0 , as well as for all its natural extensions. (This answers an open question raised twenty years ago by Paris and Wilkie [15].). (shrink)

This article will study a class of deduction systems that allow for a limited use of the modus ponens method of deduction. We will show that it is possible to devise axiom systems α that can recognize their consistency under a deduction system D provided that: (1) α treats multiplication as a 3-way relation (rather than as a total function), and that (2) D does not allow for the use of a modus ponens methodology above essentially the levels of Π1 (...) and Σ1 formulae. Part of what will make this boundary-case exception to the Second Incompleteness Theorem interesting is that we will also characterize generalizations of the Second Incompleteness Theorem that take force when we only slightly weaken the assumptions of our boundary-case exceptions in any of several further directions.

Perceptual judgments result from a dynamic process, but little is known about the dynamics of number‐line estimation. A recent study proposed a computational model that combined a model of trial‐to‐trial changes with a model for the internal scaling of discrete numbers. Here, we tested a surprising prediction of the model—a situation in which children's estimates of numerosity would be better than those of adults. Consistent with the model simulations, task contexts led to a clear developmental reversal: children made more adult‐like, (...) linear estimates when to‐be‐estimated numbers were descending over trials (i.e., backward condition), whereas adults became more like children with logarithmic estimates when numbers were ascending (i.e., forward condition). In addition, adults’ estimates were subject to inter‐trial differences regardless of stimulus order. In contrast, children were not able to use the trial‐to‐trial dynamics unless stimuli varied systematically, indicating the limited cognitive capacity for dynamic updates. Together, the model adequately predicts both developmental and trial‐to‐trial changes in number‐line tasks. (shrink)

Gödel’s Second Incompleteness Theorem states axiom systems of sufficient strength are unable to verify their own consistency. We will show that axiomatizations for a computer’s floating point arithmetic can recognize their cut-free consistency in a stronger respect than is feasible under integer arithmetics. This paper will include both new generalizations of the Second Incompleteness Theorem and techniques for evading it.

On the unorthodox ways in which people relate to each other.

In 1981, Paris and Wilkie raised the open question about whether and to what extent the axiom system did satisfy the Second Incompleteness Theorem under Semantic Tableaux deduction. Our prior work showed that the semantic tableaux version of the Second Incompleteness Theorem did generalize for the most common definition of appearing in the standard textbooks.However, there was an alternate interesting definition of this axiom system in the Wilkie–Paris article in the Annals of Pure and Applied Logic 35 , pp. 261–302 (...) which we did not examine in our year-2002 article in the Journal of Symbolic Logic. Our first goal is to show that the incompleteness results of our prior paper can generalize in this alternate context. We will also develop a formal analysis, using a new technique called Passive Induction, that is simpler than the formalism we had used before.A further reason our results are of interest is that we have shown in a companion paper published in Electronic Notes in Theoretical Computer Science 165 , pp. 213–226 that some very unorthodox axiomizations for are anti-thresholds for the Herbrandized version of the Second Incompleteness Theorem. Thus, different axiomizations for have nearly fully opposite incompleteness properties.This paper is self-contained. It will not require a knowledge of our earlier results. (shrink)

With increasing momentum for health care reform, attention is shifting to finance reform that will provide for direct methods for controlling health care spending. This article outlines the two principal paths to direct cost control and outlines a national plan that retains our multiple sources of payment, yet also contains a powerful direct cost control technique: a single fund to finance all health care.

The effectiveness of professional sanctions against violations rests upon the severity of sanctions and detection of violations. Here we examine perceptions of professional violation detection in auditing where the professional standards may conflict with the interests of the auditor’s firm. Using a sample of future and experienced auditors, we test the relationship between professional violations and auditors’ perceptions of the likelihood that severely-sanctioned violations will be discovered (a) by the audit profession, and (b) by the auditor’s firm. In our study, (...) an auditor’s belief that professional bodies are likely to detect professionalviolations relates positively to auditor professionalism. However, we find beliefs that the audit firm will detect severely-sanctioned professional violations negatively affect auditor professionalism. In our study, the lowest level of professionalism occurs when auditors believe that their own audit firm, but not the audit profession, will detect a professional violation. We also find that auditors’ internalization of professional standards relates positively to auditor professionalism. Implications for future research and practice are discussed. (shrink)

A number of recent books and articles have claimed that environmental ethics should be pluralistic; in response to these J. Baird Callicott has written a strong attack upon moral pluralism. This paper will survey briefly some of the recent work advocating moral pluralism and examine Callicott's defense of moral monism. Then it will examine the justification for building an ethical system upon more than one fundamental source of moral insight. The moral system which succeeds in taking into account all that (...) is morally relevant will be contextualist, and it might need to be pluralistic as well. (shrink)

A unique study, Beyond Certainty is a phenomenological approach to the connection between factual knowledge and moral judgment. Marietta holds logical certainty to be unnecessary for moral decision-making. In point of fact, logical certainty about our moral judgments, according to the author, is impossible. Key dilemmas in recent moral theory are caught within this impasse represented through an "is/ought" dichotomy. Marietta trumps this impasse through a return to concrete reflection on our most primal consciousness of the world.

ABSTRACT:While tone at the top is widely regarded as an important predictor of ethical behavior in organizations, we argue that recent research overlooks the various conflicting ethical tones present in many multi-organizational work settings. Further, we propose that the resolution processes promulgated in many firms and professional associations to reconcile this conflict reinforce the tone at the bottom or a tone at the top of the employee’s organization, and that both of these approaches can conflict with the tone at the (...) top of other important organizations such as professional and regulatory organizations. Here we adapt Integrative Social Contract Theory’s priority rules to propose a multi-tone reconciliation process which prioritizes conflicting ethical tones based upon features of the organization and the effects on society. Using three contextualizations, we demonstrate the effectiveness of the multi-tone reconciliation process over current processes. We conclude with recommendations for future research and implications for practice. (shrink)

What kind of futures does agro-food imaginaries enable and who can get involved in the making of agro-food futures? In this respect, what can the increasingly influential idea of circular economy potentially offer in terms of enabling more sustainable agrofood futures? We approach this task by first outlining the interconnected challenges that the agro-food system is facing related to environmental degradation, economic crises and social problems. Then we consider the way these challenges are being addressed in agro-food studies. We argue (...) that agro-food research in recent years has seen important contributions in relation to studies of alternative food networks and the “quality” turn. These research agendas have challenged the current logic of the food system in terms of offering alternative visions of future development. We highlight two examples from the literature—the eco-economy and the integrated territorial agri-food paradigm—that develop broader frameworks for rethinking the future of the agro-food system and which have distinguished themselves in contrast to the industrialized and globalized conventional food system. We find that with respect to reorienting and reconfiguring economic structures and relations all three approaches share a common goal, but circular economy stands out in relation to the actors that are included by, for example, emphasizing collaborations and partnerships with extant agro-food businesses. Also with regards to scalar politics, it would be prudent to consider the potentials offered by the increasingly influential ideas around circular economy. (shrink)

Overestimation of one’s ability to argue their position on socio-political issues may partially underlie the current climate of political extremism in the U.S. Yet very little is known about what factors influence overestimation in argumentation of socio-political issues. Across three experiments, emotional investment substantially increased participants’ overestimation. Potential confounding factors like topic complexity and familiarity were ruled out as alternative explanations. Belief-based cues were established as a mechanism underlying the relationship between emotional investment and overestimation in a measurement-of-mediation and manipulation-of-mediator (...) design. Representing a new bias blind spot, participants believed emotional investment helps them argue better than it helps others ; where in reality emotional investment harmed or had no effect on argument quality. These studies highlight misguided beliefs about emotional investment as a factor underlying metacognitive miscalibration in the context of socio-political issues. (shrink)

This book is the most comprehensive treatment available of one of the most urgent - and yet in some respects most neglected - problems in bioethics: decision-making for incompetents. Part I develops a general theory for making treatment and care decisions for patients who are not competent to decide for themselves. It provides an in-depth analysis of competence, articulates and defends a coherent set of principles to specify suitable surrogate decisionmakers and to guide their choices, examines the value of advance (...) directives, and investigates the role that considerations of cost ought to play in decisions concerning incompetents. Part II applies this theoretical framework to the distinctive problems of three important classes of individuals, many of whom are incompetent: minors, the elderly and psychiatric patients. The authors' approach combines a probing analysis of fundamental issues in ethical theory with a sensitive awareness of the concrete realities of health care institutions and the highly personal and individual character of difficult practical problems. Its broad scope will appeal to health professionals, moral philosophers and lawyers alike. (shrink)

Belongingness is a central biopsychosocial system. Challenges to belongingness (i.e. exclusion/ostracism) engender robust negative effects on affect and cognitions. Whether overinclusion – getting more than one’s fair share of social attention – favourably impacts affect and cognitions remains an open question. This pre-registered meta-analysis includes twenty-two studies (N = 2757) examining overinclusion in the context of the Cyberball task. We found that the estimated overall effect size of overinclusion on positive affect was small but robust, and the effect on fundamental (...) needs cognitions (belongingness, self-esteem, meaningful existence and control) was moderate in size and positive in direction. Notably, the effect sizes of overinclusion were smaller than the corresponding effects of exclusion. Finally, the effects of overinclusion on positive affect were greater for high, as compared to low, socially anxious individuals. Exploring the sequelae of the full range of inclusion experiences – from exclusion to overinclusion – may enrich our understanding of the functioning of the belongingness system as well as its interaction with another central biosocial system – the social status system.

Arecent trend among environmentalists (e.g., Aldo Leopold) of basing ethical norms for land use, resource management, and conservation on ecological principies such as homeostasis is examined, and a way to justify such an ethical approach through analysis of moral judgment is explored. Issues such as the is/ought impasse, the connection between value judgments and reasons for acting, and the question of whether moral judgments are definitive and categorical are treated as they relate to an ecological ethic, i.e., an environmental ethic (...) grounded in ecological science. I argue that such an ethic is in such regards as sound as more traditional approaches. (shrink)

In this essay I ask the reader to consider the “end of life” as a life stage, rather than as a health state. At one end of the life course is childhood and at the other end is elderhood. The basic inter-generational social compact in most societies is that working adults take care of their children and their parents, and count on their children to do the same for them. In developed countries, these obligations are met in part through government (...) programs, with taxpayers funding significant portions of education, health care, and income support. (shrink)

Le principe de précaution est un principe récent qui irrigue de plus en plus le droit et les droits de différents champs de la vie publique. Il modifie ce qu’on attend des décideurs et responsables publics pour prendre des mesures qui évitent ou limitent le risque encouru ou une diminution des droits à la sécurité des citoyens et personnes. Un des défis auxquels les décideurs sont confrontés est de fonder leur décision sur un avis, une recommandation ou une expertise scientifique (...) jugés indépendants et objectivés par des connaissances. Faire vivre le débat public préalable à la décision suppose des conditions telles que la transparence, la collégialité, le débat contradictoire, le doute ou encore l’inscription des décisions dans le temps et son horizon, renvoyant in fine à une réévaluation.
