The new field of quantitative health risk assessment owes its emergence much more to the 'market pull' of demand from societal decision-making processes than to dramatic advances in our ability to make the desired predictions. This paper discusses problems and opportunities in the current practice of quantitative risk estimation under three broad headings: Basic (Technical) Assessment Methodology, and Methods for Assessing Uncertainty; Conception of the Problem for Analysis, and Ways of Expressing Results; and Defining Appropriate Roles for Expert Analysts in (...) Social Decision Processes. Finally, borrowing from work of McMullin, the paper offers some criteria for judging risk assessment theories other than the generally unavailable 'goodness-of-fit' procedures. (shrink)

Quantitative risk assessment suffers from a variety of problems--some internal and others external. Dale Hattis proposes that the problems of risk assessment can be cured by the development of risk assessment theory. I agree that theory can help address some of the internal problems, such as the failure to date to take the interaction of hazardous substances with other substances in the environment into account. I argue that the external problems such as the manipulation of inherent uncertainties by (...) the politically and socially interested, however, are less amenable to rectification by theory and require political solutions.

In this paper, we report on the orientations of Turkish college students to interpersonal arguing and compare them with American students’ predispositions for arguing. In measuring the argument orientations, a group of instruments was utilized: argument motivations, argument frames, and taking conflict personally. Turkish data come from 300 college students who were asked to complete self-report surveys. Analyses contrast the mean scores of the Turkish and American respondents, offer gender-based comparisons in the Turkish data, and show whether religiosity has an (...) effect on Turkish students’ arguing orientations. In order to give an explanatory account of the argument motivations of Turkish college students, the relevant socio-cultural and political facts about Turkey were also considered. Our investigation has revealed that Turkish students have more advanced and positive understandings of interpersonal arguing compared to American ones. We have also found clear sex-typing between Turkish male and female students, and have discovered some limited evidence for religiosity’s relevance to interpersonal arguing. (shrink)

The 'Art of Life' is John Stuart Mill's name for his account of practical reason. In this volume, eleven leading scholars elucidate this fundamental, but widely neglected, element of Mill's thought. Mill divides the Art of Life into three 'departments': 'Morality, Prudence or Policy, and Æsthetics'. In the volume's first section, Rex Martin, David Weinstein, Ben Eggleston, and Dale E. Miller investigate the relation between the departments of morality and prudence. Their papers ask whether Mill is a rule utilitarian (...) and, if so, whether his practical philosophy must be incoherent. The second section contains papers by Jonathan Riley and Wendy Donner, who explore the relation between the departments of morality and aesthetics. They discuss issues ranging from supererogation to aesthetic pleasure and humanity's relationship with nature. -/- The papers in the third section consider the Art of Life's axiological first principle, the principle of utility. Elijah Millgram contends that Mill's own life refutes his claim that the Art of Life has a single axiological first principle. Philip Kitcher maintains that Mill has a dynamic axiology requiring us to continually refine our conception of the good. In the final section, three papers address what it means to put the Art of Life into practice. Robert Haraldsson locates an 'Art of Ethics' in On Liberty that is in tension with the Art of Life. Nadia Urbinati plumbs the classical roots of Mill's view of the good life. Finally, Colin Heydt develops Mill's suggestion that we regard our own lives as works of art. (shrink)

Argument-giving reasons for a view-is our model of rational dispute resolution. Fogelin suggests that certain "deep" disagreements cannot be resolved in this way because features of their context "undercut the conditions essential to arguing" . In this paper we add some detail to Fogelin's treatment of intractable disagreements. In doing so we distinguish between his relatively modest claim that some disputes cannot be resolved through argument and his more radical claim that such disputes are beyond rational resolution. This distinction, along (...) with some ofthe detail we add to Fogelin's treatment, sheds some useful light on the project of informal logic. (shrink)

In a matter of mere milliseconds, conversational partners can transform their expectations about the world in a way that accords with another person's perspective. At the same time, in similar situations, the exact opposite also appears to be true. Rather than being at odds, these findings suggest that there are multiple contextual and processing constraints that may guide when and how people consider perspective. These constraints are shaped by a host of factors, including the availability of social and environmental cues, (...) and intrinsic biases and cognitive abilities. To explain how these might be integrated in a new way forward, we turn to an adaptive account of interpersonal interaction. This account draws from basic principles of dynamical systems, principles that we argue are already expressed, both implicitly and explicitly, within a broad landscape of existing research. We then showcase an initial attempt to develop a computational framework to instantiate some of these principles. This framework, consisting of what we argue to be important mechanistic insights rendered by neural network models, is based on a promising and long-standing approach that has yet to take hold in the current domain. We argue that by bridging this gap, new insights into other theoretical accounts, such as the connections between memory and common ground information, might be revealed. (shrink)

We explored the influence of negation on cognitive dynamics, measured using mouse‐movement trajectories, to test the classic notion that negation acts as an operator on linguistic processing. In three experiments, participants verified the truth or falsity of simple statements, and we tracked the computer‐mouse trajectories of their responses. Sentences expressing these facts sometimes contained a negation. Such negated statements could be true (e.g., “elephants are not small”) or false (e.g., “elephants are not large”). In the first experiment, as predicted by (...) the classic notion of negation, we found that negation caused more discreteness in the mouse trajectory of a response. The second experiment induced a simple context for these statements, yet negation still increased discreteness in trajectories. A third experiment enhanced the pragmatic context of sentences, and the discreteness was substantially diminished, with one primary measure no longer significantly showing increased discreteness at all. Traditional linguistic theories predict rapid shifts in cognitive dynamics occur due to the nature of negation: It is an operator that reverses the truth or falsity of an interpretation. We argue that these results support both propositional and contextual accounts of negation present in the literature, suggesting that contextual factors are crucial for determining the kind of cognitive dynamics displayed. We conclude by drawing broader lessons about theories of cognition from the case of negation. (shrink)

In this article, I critique a common claim that instrumental value is a form of extrinsic value. Instead, I offer an alternative dispositional analysis of instrumental value, which holds that instrumental value can, in certain circumstances, be an example of intrinsic value. It follows, then, that a popular account of the nature of final value – or value as an end – is false: the Moorean identification of final value with intrinsic value cannot properly distinguish between value as an end (...) and value as a means.

The argument diagramming method developed by Monroe C. Beardsley in his (1950) book Practical Logic, which has since become the gold standard for diagramming arguments in informal logic, makes it possible to map the relation between premises and conclusions of a chain of reasoning in relatively complex ways. The method has since been adapted and developed in a number of directions by many contemporary informal logicians and argumentation theorists. It has proved useful in practical applications and especially pedagogically in teaching (...) basic logic and critical reasoning skills at all levels of scientific education. I propose in this essay to build on Beardsley diagramming techniques to refine and supplement their structural tools for visualizing logical relationships in a number of categories not originally accommodated by Beardsley diagramming, including circular reasoning, reductio ad absurdum arguments, and efforts to dispute and contradict arguments, with applications and analysis.

This paper explicates secular psychodynamic growth through the life time and meditation as routes to the transpersonal from the perspective of evolutionary developmental biology, based around a multi-line model of growth. A multi-line model raises many significant points for a transpersonal audience. Such models have been pioneered by Hunt. When set on the footing of evolutionary developmental biology and nonlinear dynamics these kind of models become all the more cogent, penetrating and far reaching, validating plurality and diversity in both the (...) process and final form of transpersonal development. The "anecdotal" accounts which Hunt reports, and which this paper adds to, can thus be amalgamated with an established and sophisticated research program . Such developments are symptomatic of a general movement in the sciences towards a non-linear paradigm, to which the transpersonal movement might have been slow to respond. (shrink)

Starting with this issue, Teaching Philosophy will initiate a series of articles entitled “How to Teach.” The aim of these articles is to provide an overview of how to teach a particular course commonly offered in philosophy departments and programs, with the hope that the articles will assist those who are asked to teach a course unfamiliar to them. We welcome feedback about this series and the articles contained therein.—MC.

The ability to gain knowledge from text in widely different subject matter areas is key to academic success and lifelong leaming. The process of attaining critical understanding of ideas in text requires a robust repertoire of leaming or study strategies, metacognitive knowledge for regulating their use, and willingness to apply them. Although much is known about the basic design of leaming environments to develop higher-order thinking skills and motivation to learn, educators have, in general, not changed their practices to reflect (...) new knowledge. The lack of procedures that are easy for teachers to administer and provide results that teachers may use in their classrooms for assessment of complex cognitive skill development is a major obstacle to widespread adoption of new approaches. This paper describes a new technology, referred to as HyLighter, and a pedagogically sound implementation of this technology, referred to as the Interaclive Annotation Model. This approach suggests a promising direction for improving the quality of instruction and promoting active reading (i.e., an approach to the development of leaming ability that combines reading with critical thinking and a range of learning-to-Iearn skills) for students in higher education across academic disciplines.

There is a crisis in America revolving around social and political life that the contributors to this volume believe has provoked a renewed attention to the issue of community in political thought. That attention is found most prominently in the "communitarian" movement, but it also finds expression in the views of the prominent political thinkers of our time.

In classical Greek poetry there is a familiar distinction between verse which repeats line upon line, and that which forms patterns liable to closure at intervals, in stanzas or lyric sections. This is often equated with the distinction between spoken and sung verse, but the equation is only approximate. At an earlier stage all verse had some musical accompaniment—so much can be deduced from a number of passages in Homer, and is in any case implicit in the nature of quantitative (...) verse. By Hellenistic times it seems that, in new composition, the more complex lyric structures had died out, while of the simpler ones more and more were being taken over as spoken verse. In the fifth century—and this can probably be extended to at least the late sixth and most of the fourth—only two kinds of verse are known to have dispensed with music altogether in performance: the heroic hexameter and the iambic trimeter.

This paper offers an argument against V. H. Dudman's view about future conditionals.

When Putin became president at the beginning of the 21st century, Russia was in shambles. Putin saw his task to be two fold. First, to recreate the Russian state – that had been seriously weakened by Boris Yeltsin. Second, he set out to reestablish Russia as an important international actor. His approach to dealing with those two tasks was heavily influenced by his approach to dealing with political problems. He is determined, but non ideological. He believes that Russia is unique (...) and that only "Russian" solutions will resolve the country’s problems. Most of all, Putin sees himself as a "problem solver," something that comes from his years in the KGB. And while much remains to be done, he did a lot to solve Russia’s problems. The power of the state has been restored, and Russia is taken far more seriously on the international stage than it was in 2000. What is amazing, given all of the criticism he has received in the West for his "undemocratic" actions, his standings in the polls for the eight years he was in office remained above 70%, something a Western politician can only dream of.

This paper uses Paul Ricœur’s analyses of ideology to argue for the mitigation of the possibility of political evil within the political paradox. In explicating the paradox, Ricœur seeks to hold in tension two basic aspects of politics: its benefits and its propensity to evil. This tension, however, should not be viewed as representative of a dualism. The evil of politics notwithstanding, Ricœur encourages us to view the political order as a deeply important part of our shared existence. By thinking (...) past the distorting function of ideology to the legitimating and integrating functions that Ricœur calls more basic than distortion, a mode of thought that is often at the heart of political evil, ideology can be used to mitigate that very evil. Keywords: Ri cœur, “The Political Paradox,” Ideology, Political Violence, Justice. Résumé Cet article s’appuie sur les analyses ricœuriennes de l’idéologie dans le but de montrer que l’idéologie est susceptible de contribuer à une atténuation du mal politique inhérent au paradoxe politique. Dans son explicitation de ce paradoxe, Ricœur cherche à mettre en relation tensionnelle deux aspects fondamentaux de la politique: ses avantages et ses maux. Cependant, cette tension ne devrait pas être interprétée comme l’expression d’un dualisme. En dépit du mal inhérent au politique, Ricœur nous encourage à voir l’ordre politique comme une partie profondément importante de notre existence partagée. Si l’on régresse en-deçà de la fonction de distorsion de l’idéologie vers ses fonctions légitimantes et integratrices, c’est-à-dire vers ses fonctions les plus fondamentales, il apparaît en effet que l’idéologie, tout en étant souvent au cœur du mal politique, peut néanmoins être utilisée pour atténuer ce mal. Mots-clés: Ricœur, paradoxe politique, ideologie, violence politique, justice. (shrink)

This article critiques Elizabeth Grosz's understanding that queer theory is unproductive insofar as it disrupts the specific identities of gay and lesbian. Reconsidering ideas about desire, the body, and identity that Grosz takes from Gilles Deleuze's work on Friedrich Nietzsche and Baruch Spinoza, this essay argues that, despite her productive reworking of homophobia in terms of “active” and “reactive” forces, Grosz's application of Spinoza is only partial. Focusing on Spinoza's evaluation of bodies, the essay both critiques Grosz's approach to experimental (...) desire and observes Spinozist preoccupations in order to talk about the experimental body. It concludes that if Grosz were to attend more seriously to the Spinozist imperative to analyze a body in terms of its capabilities—that is, its power to be affected—the epistemological basis of her argument would change. It would be difficult to dismiss the plurality and sensibility of a queer body or its challenge to lesbian and gay as the source of a primary identity. (shrink)

During somitogenesis an oscillatory mechanism termed the “segmentation” clock generates periodic waves of gene expression, which translate into the periodic spatial pattern manifest as somites. The dynamic expression of the clock genes shares the same periodicity as somitogenesis. Notch signaling is believed to play a role in the segmentation clock mechanism. The paper by Hirata et al.(1) identifies a biological clock in cultured cells that is dependent upon the Notch target gene Hes1, and which shows a periodicity similar to that (...) of the segmentation clock. This finding opens the possibility that the same oscillator mechanism might also operate in other tissues or cell types. BioEssays 25:200–203, 2003. © 2003 Wiley Periodicals, Inc. (shrink)
