Abstract This article revisits a reduced model of cardiac electro-physiology which was proposed to understand the genesis of unidirectional block pathology and of ectopic foci. We underline some specificities of the model from the viewpoint of dynamical systems and bifurcation theory. We point out that essentially the same properties are shared by a simpler system more accessible to analysis. With this simpler system, it becomes possible to give a new presentation of the phenomenon in a phase plane with time moving (...) slow manifolds. This presentation can be of interest both for cardiac electro-physiologists and for mathematicians.

This essay explains for a general philosophical audience the central issues and strategies in the contemporary moral realism debate. It critically surveys the contribution of some recent scholarship, representing expressivist and pragmatist nondescriptivism (Mark Timmons, Hilary Putnam), subjectivist and nonsubjectivist naturalism (Michael Smith, Paul Bloomfield, Philippa Foot), nonnaturalism (Russ Shafer-Landau, T. M. Scanlon) and error theory (Richard Joyce). Four different faces of ‘moral realism’ are distinguished: semantic, ontological, metaphysical, and normative. The debate is presented as taking shape under dialectical (...) pressure from the demands of (i) capturing the moral appearances and (ii) reconciling morality with our understanding of the mind and world.

Metaethics is a perennially popular subject, but one that can be challenging to study and teach. As it consists in an array of questions about ethics, it is really a mix of (at least) applied metaphysics, epistemology, philosophy of language, and mind. The seminal texts therefore arise out of, and often assume competence with, a variety of different literatures. It can be taught thematically, but this sample syllabus offers a dialectical approach, focused on metaphysical debate over moral realism, which spans (...) the century of debate launched and framed by G. E. Moore's Principia Ethica. The territory and literature are, however, vast. So, this syllabus is highly selective. A thorough metaethics course might also include more topical examination of moral supervenience, moral motivation, moral epistemology, and the rational authority of morality. Authors Recommend: Alexander Miller, An Introduction to Contemporary Metaethics (Cambridge: Polity Press, 2003). This is one of the few clear, accessible, and comprehensive surveys of the subject, written by someone sympathetic with moral naturalism. David Brink, Moral Realism and the Foundations of Ethics (Cambridge: Cambridge University Press, 1989). Brink rehabilitates naturalism about moral facts by employing a causal semantics and natural kinds model of moral thought and discourse. Michael Smith, The Moral Problem (Oxford: Blackwell, 1994). Smith's book frames the debate as driven by a tension between the objectivity of morality and its practical role, offering a solution in terms of a response-dependent account of practical rationality. Gilbert Harman and Judith Jarvis Thomson, Moral Relativism & Moral Objectivity (Cambridge, MA: Blackwell, 1996). Harman argues against the objectivity of moral value, while Thomson defends it. Each then responds to the other. Frank Jackson, From Metaphysics to Ethics (Oxford: Clarendon Press, 1998). Jackson argues that reductive conceptual analysis is possible in ethics, offering a unique naturalistic account of moral properties and facts. Mark Timmons, Morality without Foundations (Oxford: Oxford University Press, 1999). Timmons distinguishes moral cognitivism from moral realism, interpreting moral judgments as beliefs that have cognitive content but do not describe moral reality. He also provides a particularly illuminating discussion of nonanalytic naturalism. Philippa Foot, Natural Goodness (New York, NY: Oxford University Press, 2001). A Neo-Aristotelian perspective: moral facts are natural facts about the proper functioning of human beings. Russ Shafer-Landau, Moral Realism: A Defence (New York, NY: Oxford University Press, 2003). In this recent defense of a Moorean, nonnaturalist position, Shafer-Landau engages rival positions in a remarkably thorough manner. Terence Cuneo, The Normative Web (New York, NY: Oxford University Press, 2007). Cuneo argues for a robust version of moral realism, developing a parity argument based on the similarities between epistemic and moral facts. Mark Schroeder, Slaves of the Passions (New York, NY: Oxford University Press, 2007). Schroeder defends a reductive form of naturalism in the tradition of Hume, identifying moral and normative facts with natural facts about agents' desires.

The contents of the inaugural volume of Oxford Studies in Metaethics nicely mirror the variety of issues that make this area of philosophy so interesting. The volume opens with Peter Railton's exploration of some central features of normative guidance, the mental states that underwrite it, and its relationship to our reasons for feeling and acting. In the next offering, Terence Cuneo takes up the case against expressivism, arguing that its central account of the nature of moral judgments is badly mistaken. (...) Terence Horgan and Mark Timmons, two of the most prominent contemporary expressivists, then offer their take on how expressivism manages to avoid a different objection-that of collapsing into an objectionable form of relativism. Daniel Jacobson and Justin D'Arms next offer an article that continues their research program devoted to exploring the extent to which values might depend upon, or be constrained by, human psychology. Ralph Wedgwood engages in some classical metaethical conceptual analysis, seeking to explicate the meaning of ought. Mark van Roojen then contributes a new take on the Moral Twin Earth Argument, a prominent anti-realist puzzle advanced in the early 1990s by Horgan and Timmons. -/- Allan Gibbard next presents his latest thoughts on the nature of moral feelings and moral concepts, crucial elements in the overall project of defending the expressivism he is so well known for. James Dreier then takes up the details of Gibbard's recent efforts to provide a solution to what many view as the most serious difficulty for expressivism, namely, the Frege-Geach problem. Dreier identifies difficulties in Gibbard's expressivist account, and offers a suggestion for their solution. Sergio Tenenbaum explores the concept of a direction of fit, relied on so heavily nowadays in accounts of moral motivation. Nadeem Hussain and Nishiten Shah then consider the merits of Christine Korsgaard's influential critique of moral realism. T. M. Scanlon's widely-discussed buck-passing account of value attracts the critical eye of Pekka Väyrynen, who attempts to reveal the reasons that we might resist it. Derek Parfit's contribution concludes this volume, with an article on normativity that presents his most recent thinking on this fundamental notion. (shrink)
