Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

OBJECTIVE: To describe the issues faced, and how they were addressed, by the University of Toronto Critical Care Medicine Program/Joint Centre for Bioethics Task Force on Appropriate Use of Life-Sustaining Treatment. The clinical problem addressed by the Task Force was dealing with requests by patients or substitute decision makers for life-sustaining treatment that their healthcare providers believe is inappropriate. DESIGN: Case study. SETTING: The University of Toronto Joint Centre for Bioethics/Critical Care Medicine Program Task Force on Appropriate Use of Life-Sustaining (...) Treatment. PARTICIPANTS: The 24-member Task Force included physician and nursing leaders from five critical care units, bioethicists, a legal scholar, a health administration expert, a social worker, and a hospital public relations professional. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Our specific lessons learned include a) a policy focus on process; b) use of a negotiation and mediation model, rather than a hospital ethics committee model, for this process; and c) the policy development process is itself a negotiation, so we recommend equal involvement of interested groups including patients, families, and the public. CONCLUSIONS: This article describes the key issues faced by the Task Force while developing its policy. It will provide a useful starting point for other groups developing policy on appropriate use of life-sustaining treatment. (shrink)

Athenaeus records these lines from the dithyramb Hymenaios, along with a number of other snippets of poetry, in the course of an inconclusive discussion about the characteristics of the instrument called the magadis. Athenaeus had good reasons for being puzzled; the word first appeared in Greek, so far as we know, in the seventh century b.c., and its sense was already a matter of some doubt in the fourth. As to this particular fragment, even Telestes' original audience might be forgiven (...) some bafflement in the face of the third line, on which I shall initially focus here. What can be meant by ‘the five-rodded joining of the strings’? (shrink)

Physics has been thought to truly represent reality since at least Galileo, and the foundations of physics are always established using philosophical ideas. In particular, the elegant naming of physical entities is usually very influential in the acceptance of physical theories. We here demonstrate (using current developments in thermodynamics as an example) that both the epistemology and the ontology of physics ultimately rest on poetic language. What we understand depends essentially on the language we use. We wish to establish our (...) knowledge securely, but strictly speaking this is impossible using only analytic language. Knowledge of the meanings of things must use a natural language designed to express meaning, that is, poetic language. Although the world is really there, and although we can indeed know it truly, this knowledge is never either complete or certain but ultimately must rest on intuition. Reading a recently discovered artefact with a palaeo-Hebrew inscription as from the first century, we demonstrate from it that this ontological understanding long predates the Hellenic period. Poetic language is primary, both logically and temporally. (shrink)

The United Nations Convention on the Rights of the Child risks harm to adolescents insofar as it encourages not only poor decision making by adolescents but also parenting styles that will have an adverse impact on the development of mature decision-making capacities in them. The empirical psychological and neurophysiological data weigh against augmenting and expression of the rights of children. Indeed, the data suggest grounds for expanding parental authority, not limiting its scope. At the very least, any adequate appreciation of (...) the moral claims regarding the authority of parents with respect to the decision-making capacity of adolescents needs to be set within an understanding of the psychological and neurophysiological facts regarding the development of adolescent decision-making capacity.

According to both deontologists and consequentialists, if there is a reason to promote the general happiness – or to promote any other state of affairs unrelated to one's own projects or self-interest – then the reason must apply to everyone. This view seems almost self-evident; to challenge it is to challenge the way we think of moral reasons. I contend, however, that the view depends on the unwarranted assumption that the only way to restrict the application scope of a reason (...) for action is by restricting it to those agents whose interests or projects are involved in the reason. In fact normative theories may coherently restrict application scopes in other ways. Thus we must take seriously the possibility that the reason to promote the general happiness, although genuine, does not apply to everyone. (shrink)

I give the label “ethical pluralism” to the meta-ethical view that competing moral views are valid. I assume that validity is conferred on a moral view by its satisfying the relevant meta-ethical criteria in a maximally satisfactory way. If the relevant meta-ethical criteria are based on something roughly like the wide reflective equilibrium model, then ethical pluralism is likely to be correct. Traditional moral views do not grant exemptions from their own binding rules or principles to agents – should any (...) exist – who adhere to a competing valid moral view. Given the usual conception of accepting a moral view, an ethical pluralist cannot honestly accept a traditional moral view. Consequently, I argue, an ethical pluralist is committed to the view that all traditional moral views are invalid. Given the likelihood of ethical pluralism, this conclusion is alarming. I set forth a weak conception of accepting a moral view that is designed to allow an ethical pluralist honestly to accept a traditional moral view. In particular, my conception is designed to explain how someone can (a) be guided by the view that she accepts; (b) accept her own moral view while rationally not accepting competing views that she thinks are equally valid; and (c) not be prepared to prescribe morally to those who are following other valid views. Central to my formulation are what I call a stance of modest respectful disapproval toward other people’s wrong behavior, together with acceptance of decisive moral reasons for oneself that are generated by the valid moral view that one accepts.

W. D. Ross’s ethical theory requires us somehow to compare the metaphorical “weights” of different prima facie duties, but it leaves mysterious how this might be done. The formulation of a procedure to achieve such a comparison would be desirable on practical, theoretical, and pedagogical grounds. I formulate a procedure that is congenial to Ross’s theory. Central to my procedure are instructions to characterize the weight of each prima facie duty with respect to (a) the general stringency of this kind (...) of duty, (b) the stringency of this particular duty relative to other duties of its own kind, and (c) the degree to which the duty specifically demands the particular action that it favors in a given case. The procedure leads to a determination of one’s actual, all-things-considered duty in some cases but not in all. (shrink)

The social, educational and political writings of Jean-Jacques Rousseau have become enormously influential in the 200 years since his death. But the breadth as well as the depth of Rousseau's achievement - he was amongst other things a creative writer and musical composer as well as a philosopher - is not always appreciated. In around 100 articles, alphabetically arranged and fully cross-referenced, N. J. H. Dent explores all facets of Rousseau's work and thoughts, while his subject's remarkable life is summarized (...) in a biographical introduction. Details of works by and about Rousseau are listed in an extensive bibliography. For students or general readers seeking an introduction to Rousseau's work, and for those already familiar with the material who require a convenient reference source, this dictionary is essential reading.

The systems approach to niche presented herein stands as an example of the unifying potential of mathematical system theory when applied to concepts and principles of ecology. Beginning with subjective concepts from the naturalistic tradition, the niche was framed in the formalism of general system theory. So modeled, it appeared as a restriction of a more general construct, the environ. Both niches and environs are implementable in the context of ecosystem models, and with the growing ability of ecologists to construct (...) such models, system theoretic niches and environs both should serve in the future to clarify old problems of ecology, and make it possible to raise new classes of problems. The nature of niches, always difficult conceptually for the ecologist, may now give way to further development, both theoretical and empirical. (shrink)
