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)

It seems to be generally accepted that (a) counterfactual conditionals are to be analysed in terms of possible worlds and inter-world relations of similarity and (b) causation is conceptually prior to counterfactuals. I argue here that both (a) and (b) are false. The argument against (a) is not a general metaphysical or epistemological one but simply that, structurally speaking, possible worlds theories are wrong: this is revealed when we try to extend them to cover the case of probabilistic counterfactuals. Indeed (...) a type of counterfactual probability exists which cannot be expressed in possible worlds terms at all. The argument against (b) emerges when we look at the form of an adequate account of both probabilistic and non-probabilistic counterfactuals. I do this by sketching and defending an approach to counterfactuals that, first, invoke a generalized notion of cause as primitive and, secondly, is algorithmic in form: counterfactuals are evaluated algorithmically in terms of other counterfactuals, without vicious circularity. Structures like possible worlds do not play a role either in general truth-conditions or in evaluation. They are simply the wrong sorts of structures. (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)

Kant wrote two versions of the Transcendental Deduction, the first, “A-”Deduction in 1781, and the second, “B-”Deduction in 1787. Since Henrich's “The Proof Structure of Kant's Transcendental Deduction”, most work on the Transcendental Deduction attempts to make sense of the B-Deduction's two-step argument structure. Though the A-Deduction has suffered comparative neglect, it has received some attention from interpreters who take its extended treatment of the “subjective” side of cognition to amount to a brand of proto-functionalism. Whatever the merits and demerits (...) of these proto-functionalist approaches, they tend to deemphasize the two arguments that constitute the “objective” side of the A-Deduction, the “argument from above” and then the “argument from below”. Since Kant himself refers to this objective side of the A-Deduction as the “Deduction of the Pure Concepts of the Understanding”, it is surprising that the structure of these arguments has not received closer scrutiny. This is doubly true since Kant actually claims that his revisions for the 1787 version of the Deduction impacted only the “presentation” of it. Any lessons learned from the central arguments of the A-Deduction should help clarify the structure of its younger and more closely studied brother. (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)

This paper first traces the general influence of Ernest Barker's undergraduate training in Oxford's School of Literae Humaniores on his later work on ancient political thought, and in particular shows how Idealism conditioned his view that the major ancient texts were perennially relevant and also applicable to practical affairs. The second part of the paper is based on a letter that Barker wrote to E.R. Dodds in 1953 critical of Dodds's negative perspective in The Greeks and the Irrational (...) on the religious culture of the early centuries of the Roman Empire. This document offers a revealing insight into the gulf between Barker's Christian values and optimistic view of the evolution of the classical tradition and Dodds's pessimistic secularism, which had its theoretical basis in ideas drawn from social psychology which Barker had always despised.

Stephen Barker argues that a possible worlds semantics for the counterfactual conditional of the sort proposed by Stalnaker and Lewis cannot accommodate certain examples in which determinism is true and a counterfactual Q > R is false, but where, for some P, the compound counterfactual P > (Q > R) is true. I argue that the completeness theorem for Lewis’s system VC of counterfactual logic shows that Stalnaker–Lewis semantics does accommodate Barker’s example, and I argue that its doing (...) so should be understood as showing that the example is an exception to Lewis’s Time’s Arrow requirements.

Professor S. F. Barker has recently argued that the theory of the status of theoretical concepts in natural science put forward by Hempel and Braithwaite is mistaken. Essentially this "formalistic" theory says that these concepts "take on" meaning from their place in a total theoretical system which as a whole implies testable observation statements. In the paper it is argued that Barker's criticism of the Hempel-Braithwaite theory is mistaken because (a) he does not sufficiently consider the operative empirical (...) restrictions on concept formation in scientific theorizing, and (b) his criticisms are based on an acceptance of a narrow empiricism which would reject most existing theoretical natural science as empirically meaningless.

In this book Harry Heft examines the historical and theoretical foundations of James J. Gibson's ecological psychology in 20th century thought, and in turn, integrates ecological psychology and analyses of sociocultural processes. A thesis of the book is that knowing is rooted in the direct experience of meaningful environmental objects and events present in individual-environment processes and at the level of collective, social settings. Ecological Psychology in Context: *traces the primary lineage of Gibson's ecological approach to William James's philosophy of (...) radical empiricism; *illuminates how the work of James's student and Gibson's mentor, E.B. Holt, served as a catalyst for the development of Gibson's framework and as a bridge to James's work; *reveals how ecological psychology reciprocally can advance Jamesian studies by resolving some of the theoretical difficulties that kept James from fully realizing a realist philosophy; *broadens the scope of Gibson's framework by proposing a synthesis between it and the ecological program of Roger Barker, who discovered complex systems operating at the level of collective, social processes; *demonstrates ways in which the psychological domain can be extended to properties of the environment rendering its features meaningful, publicly accessible, and distributed across person-environment processes; and *shows how Gibson's work points the way toward overcoming the gap between experimental psychology and the humanities. Intended for scholars and students in the areas of ecological and environmental psychology, theoretical and historical psychology, cognitive science, developmental psychology, anthropology, and philosophy.

The view that it is better for life to be created free of disability is pervasive in both common sense and philosophy. We cast doubt on this view by focusing on an influential line of thinking that manifests it. That thinking begins with a widely-discussed principle, Procreative Beneficence, and draws conclusions about parental choice and disability. After reconstructing two versions of this argument, we critique the first by exploring the relationship between different understandings of well-being and disability, and the second (...) by more briefly focusing on the idea of a significant reason. By placing these results against the broader historical and ongoing contexts in which the lives of those with disabilities have been deemed of inferior quality, we conclude with a call for greater humility about disability and well-being in thought and practice.

Are the sculpture and the mass of gold which permanently makes it up one object or two? In this article, we argue that the monist, who answers ‘one object’, cannot accommodate the asymmetry of material constitution. To say ‘the mass of gold materially constitutes the sculpture, whereas the sculpture does not materially constitute the mass of gold’, the monist must treat ‘materially constitutes’ as an Abelardian predicate, whose denotation is sensitive to the linguistic context in which it appears. We motivate (...) this approach in terms of modal analyses of material constitution, but argue that ultimately it fails. The monist must instead accept a deflationary, symmetrical use of ‘materially constitutes’. We argue that this is a serious cost for her approach. (shrink)

This volume presents new work in history and historiography to the increasingly broad audience for studies of the history and philosophy of science. These essays are linked by a concern to understand the context of early modern science in its own context.

Three arguments for the conclusion that objects cannot endure in B-time even if they remain intrinsically unchanged are examined: Carter and Hestevolds enduring-objects-as-universals argument (American Philosophical Quarterly 31(4):269-283, 1994) and Barker and Dowe's paradox 1 and paradox 2 (Analysis 63(2):106-114, 2003, Analysis 65(1):69-74, 2005). All three are shown to fail.
