Summary Sexual communication in most species of fireflies is a male±female dialogue of precisely timed flashes of bioluminescent light. The biochemical reactions underlying firefly bioluminescence have been known for 30 years and are now exploited in biomedical assays and other commercial applications. Several aspects of flash regulation are also understood: flash rhythm is controlled by a central pattern generator, and individual flashes are neurally triggered, with octopamine serving as the transmitter. The molecular oxygen needed by the biochemical reactants is delivered (...) by a network of tracheal arborizations extending throughout the light organ (lantern).However, the actual means by which oxygen quickly reaches the reactants packaged within specialized photocytes and the specific event(s) triggered by neural action have not been identified; termination of axons away from the photocytes has exacerbated the latter problem. A recent paper(1) by a consortium of cell and evolutionary biologists, however, reports that nitric oxide (NO), manufactured and released in response to neuronal discharge, is the missing link by which neural action in the firefly lantern yields a sudden flash of light.

Draws on interviews with many of the worlds leading scientists to discuss the possibility that humankind has reached the limits of scientific knowledge.

Some of the most forceful objections to William Wollaston's moral theory come from his early critics, namely, Thomas Bott (1688-1754), Francis Hutcheson (1694-1746), and John Clarke of Hull (1687-1734). These objections are little known, while the inferior objections of Hume, Bentham, and later prominent critics are familiar. This fact is regrettable. For instance, it impedes a robust understanding of eighteenth-century British ethics; also, it fosters a questionable view as to why Wollaston's theory, although at first well received, soon faded (...) in esteem among philosophers. This paper gives Wollaston's early critics some of the attention they deserve. It reconstructs some of their objections to Wollaston's philosophy, addresses replies to those objections, and shows that despite some minor flaws, the objections succeed. A fact that becomes clear is that Wollaston's philosophy had suffered devastating criticism years before Hume wrote anything against it. (shrink)

This interview with John Cottingham explores some major themes in his recent work in moral philosophy and the philosophy of religion. It begins by discussing his views on the task of philosophy and focuses particularly on philosophy’s role in achieving an overall view of the world and for understanding and achieving the good life. It also discusses some ‘limits of philosophy’ with respect to understanding and achieving the good life; i.e., some ways in which philosophical reflection on the good (...) life needs to draw on insights found in other domains such as psychoanalysis and religious faith and spiritual practice. The role of philosophy and spiritual practice in coming to religious faith and supporting it is also discussed. (shrink)

"Don't believe any of this. Place no value in the book, in the author. Give it up, the idea of author, of truth. Give up all believe: believe only in yourself. You: you are nothing but my experience. Me: I don't. I don't believe any of this." —John Brockman.

Thornhill, John Among the thinkers who have helped me expand my intellectual horizons, Dawson has a unique place. From an early date, I became aware of the importance of situating the Church's expression of our faith tradition in its historical and cultural context. In time I was to find that Dawson's interpretation of cultural history made it possible to do this within the enlightening framework he provided.

Each chapter heading bears a phrase from a contemporary author, held to incorporate the character of that section of the study under consideration. Chapter 1 carries the title given to early English translations of the Lettres provinciales; chapter 2 recalls the description of Pascall by Boyle and other English scientists; and chapter 3 draws from Kennett's preface to his version of the Pensees. The heading of chapter 4 is from Pope's Essay on Man. The exclamation which introduces chapter 5 concludes (...) an essay in the Gentleman's Magazine for 1789, probably by Boswell; the words for chapter 6 come from a pastoral letter of John Wesley; and chapter 7 represents the verdict of Coleridge. The title of the book itself is derived from the heading to the twenty-first chapter of Kennett's Pensees, which seems to have forecast the essence of the eighteenth-century's perplexity upon the issues raised by Pascal: 'The strange Contrarieties discoverable in Human Nature, with regard to Truth, and Happiness, and many other things.'.

In Adulthood, Morality, and the Fully Human, John Shea examines what it means for someone to achieve full moral development or to become what he calls “fully human.” Shea highlights integrity, mutuality, care, and justice as core components of this process and depicts the effects of personal growth on education, psychotherapy, and spirituality.

Over the past two centuries Western culture has largely valorized a particular kind of 'good' music--highly serious, wondrously deep, stylistically authentic, heroically created, and strikingly original--and, at the same time, has marginalized music that does not live up to those ideals. In Good Music, John J. Sheinbaum explores these traditional models for valuing music. By engaging examples such as Handel oratorios, Beethoven and Mahler symphonies, jazz improvisations, Bruce Springsteen, and prog rock, he argues that metaphors of perfection do justice (...) to neither the perceived strengths nor the assumed weaknesses of the music in question. Instead, he proposes an alternative model of appreciation where abstract notions of virtue need not dictate our understanding. Good music can, with pride, be playful rather than serious, diverse rather than unified, engaging to both body and mind, in dialogue with manifold styles and genres, and collaborative to the core. We can widen the scope of what music we value and reconsider the conventional rituals surrounding it, while retaining the joys of making music, listening closely, and caring passionately"-- $c Page [4] of cover.

The Foundations of Pragmatism in American Thought Series offers two sets of volumes containing the most significant defenses and critiques of pragmatism written before World War I: the Early Defenders of Pragmatism and Early Critics of Pragmatism. This, the first collection, Early Defenders, provides key texts for understanding the context of pragmatism's years of greatest vitality. The early defenders were products of pragmatism's three cradles. H. Heath Bawden was a graduate of the Chicago philosophy department, having studied with John (...) Dewey and George Mead. John E. Boodin and Horace M. Kallen earned their Ph.Ds with William James and Josiah Royce at Harvard. D. L. Murray and Howard V. Knox were independent scholars and writers inspired by F. C. S. Schiller's humanistic pragmatism at Oxford. This collection brings together the central texts of the movement along with a representative selection of the secondary texts, reviews and responses, they elicited. Each volume features a newly-commissioned introduction by a leading scholar of American pragmatism. --five central texts reproduced in facsimile, accompanied by the main responses and replies, reset in new typography --scattered and scarce works available together for the first time --new introductions to each volume by leading scholars of American pragmatism.

John Haught offers a “critical intelligence” argument against naturalism. In this article, I outline Haught’s version of theistic evolution. Then I discuss the case he makes against naturalism with his critical intelligence argument. He uses two versions of the argument to make his case: a trustworthiness of critical intelligence argument and an ineffectiveness of naturalistic theories of the mind argument. I evaluate both versions of his critical intelligence argument against naturalism and find that they contain false premises. They thus (...) come up short in making a strong case against naturalism.

During the last 40 years, political philosophers have made important advances in our understanding of why equality is valuable, and what kind of equality is important. This article summarizes the development of these ideas, in particular, the contributions of John Rawls, Amartya Sen, Ronald Dworkin, Robert Nozick, Richard Arneson, and G. A. Cohen. It shows how these ideas have filtered into economic thinking in the conceptualization of equality of opportunity. It concludes with a brief discussion of how these ideas (...) might be extended to evaluate intergenerational and global distributions of income or welfare. (shrink)

RECENT JEWISH—CHRISTIAN DIALOGUE HAS UNCOVERED THAT THE EARLY church's ethics were firmly rooted in Jewish halakhic thinking. This essay explores the topic through a study of the church's moral reasoning in Acts 10—15. We see the church readily employing distinctions that are now rarely invoked by Christian ethicists, such as between universal and particular moral law. These distinctions allowed the church to understand the ethical significance of the Torah not by imposing external categories on it but through the Torah's own, (...) internal distinctions. Thus, the church's understanding of the Torah can best be understood through the image of geirei toshav. This image could help Christian ethicists understand their relation to pluralistic contexts because it was precisely the increased pluralism of gentile inclusion that prompted the church in Acts. I briefly consider the implications for a concrete case: the Episcopal-Anglican Communion's debate about homosexuality, which employs the Acts 10—15 narrative. (shrink)

OBVIOUSLY, OBSERVERS EXIST ONLY WHERE LIFE IS POSSIBLE ("THE ANTHROPIC PRINCIPLE"). NOW, THERE MAY BE MANY COSMIC REGIONS, PERHAPS GIGANTIC AND LARGELY OR ENTIRELY SEPARATE "MULTIPLE UNIVERSES," OF WHICH ONLY VERY FEW PERMIT LIFE’S EVOLUTION. GUTH’S COSMIC INFLATION MAY BE INVOLVED HERE, AND DOMAINS WITH DIFFERENTLY BROKEN SYMMETRIES. APPARENT LIFE-ENCOURAGING FINE-TUNING OF NATURAL CONSTANTS MIGHT BE UNDERSTOOD AGAINST THIS BACKGROUND. MANY SCIENTISTS PREDICTIONS RESULT. AN ALTERNATIVE ACCOUNT SPEAKS OF THE WORLD’S CREATIVE ETHICAL REQUIREDNESS ("GOD").

What demands must be met for phenomenology to be the rigorous science Husserl projected? Janicaud complains that some French phenomenologists, while pretending to observe these demands, play fast and loose with them when they apply phenomenology to matters of theology: Derrida, Marion, and Levinas; methodological phenomenology and Henry's phenomenology of the Christian Way. Derrida's deconstructions of the oppositions of immanence and transcendence and of the factual and the transcendental suggest that the rift between him and Henry is not as deep (...) as it must at first seem. Analogical appresentation is a motive of the theological turn. (shrink)

Le livre III de l’Essai de Locke passe pour un des textes importants que la fin du XVIIe siècle consacre exclusivement au langage. Mais il ne faut pas s’attendre à y trouver un traité de linguistique innovant dans un champ vierge; même si Locke découvre tardivement l’importance du nom dans le savoir, il lui est facile de trouver autour de lui suffisamment de travaux pour prendre position, critiquer, simplifier, réorienter. Réorienter car son étude du nom ne vise qu’à préparer un (...) traité de la connaissance, non à faire de la linguistique pour elle-même. Il simplifie de ce fait les travaux que le Scolastique nominaliste notamment avait multipliés. Il critique tous ceux qui dissocient le mot de la double “référence” qui lui est “naturelle” : l’idée et la chose; contre Hobbes mais aussi contre les théoriciens des langues universelles, il ancre les langues dans l’usage commun d’une part, dans le rapport incertain aux choses d’autre part, toujours par la médiation de la pensée individuelle. Il prend enfin position : le nom est l’instrument privilégié de l’abstraction et de la généralisation : indispensable pour la communication et l’accumulation du savoir, il est aussi le lieu de toutes les illusions. Par son approche des espèces naturelles, par sa critique de l’essentialisme qui restaure paradoxalement l’abstrait et l’universel, par sa réduction du langage à la communication d’informations, plus que par sa théorie linguistique, ce texte nous donne encore à penser.
