Coherentist Contraction

A model of coherentist belief contraction is constructed. The outcome of belief contraction is required to be one of the coherent subsets of the original belief set, and a set of plausible properties is proposed for this set of coherent subsets. The contraction operators obtained in this way are shown to coincide with well-known belief base operations. This connection between coherentist and foundationalist approaches to belief change has important implications for the philosophical interpretation of models of belief change.     

Dualism and its Importance for Medicine

Cartesian dualism has been viewed by medical theorists to be oneof the chief causes of a reductionist/mechanistic treatment ofthe patient. Although I aver that Cartesian dualism is one culprit for the misapprehension of the genuine treatment of patients in termsof both mind and body, I argue that interactive dualism whichstresses the interaction of mind and body is essential to treatpatients with dignity and compassion. Thus, adequate medical carethat is humanistic in nature is difficult (if not impossible)to achieve without physicians adhering to a dualistic frameworkin which the body and person is treated during illness.     

A note on the equivalence of the graded response model and the sequential model

This paper concerns items that consist of several item steps to be responded to sequentially. The item scoreX is defined as the number of correct responses until the first failure. Samejima's graded response model states that each steph=1,...,m is characterized by a parameterb _h , and, for a subject with ability, Pr(Xh; )=F(–b _h ). Tutz's general sequential model associates with each step a parameterdh, and it states that Pr(Xh;)= _r ^=1h G(–d _r ). Tutz's (1991, 1997) conjectures that the models are equivalent if and only ifF(x)=G(x) is an extreme value distribution. This paper presents a proof for this conjecture.     

The Morality System with and without God

What I set out to do is to cast some doubt on the thesis that, in Bernard Williams's words, any appeal to God in morality either adds nothing at all, or it adds the wrong sort of thing. A first conclusion is that a morality of real, inescapable and (sometimes) for the agent costly obligations, while being at home in a theistic metaphysic, does not sit easily with metaphysical, atheistic naturalism. The second conclusion is that Christine Korsgaard's impressive ethical project which is neutral towards theism and atheism fails in giving a satisfying account of such obligations. My final claim is that a theistic account in terms of a strong divine command theory might succeed where non- and atheistic accounts seem to founder.     

Dynamic analyses of mother-child interactions in functional and dysfunctional dyads: a synergetic approach

Describes the application of a new analytical approach (derived from synergetics, a complex dynamic systems theory) to home observational data of mother–child interactions in average dyads and dyads with children referred for disruptive behavior problems at home and school (n = 11 in each group). Results show that (1) the two groups differed in their daily interactions in predictable ways, and (2) the most frequent patterns of interactions observed in the two groups brought them back repeatedly to behave in similar ways toward each other. The findings are in keeping with a body of literature on mother–child interactions. However, they add to it by providing multivariate, graphical representations of these interactions and by offering a conceptual framework within which to move from an observational to an inferential level of analysis. At that level, the transactional processes that are characteristic of functional and dysfunctional relationships may become apparent.     

Style in Philosophy: Part I

In this article, I attempt to restore the philosophical significance of that nonformalizable, noniterable, "singular' element of natural language that I call "style." I begin by critically addressing the exclusion of such instances of natural language by both semantics-oriented logical analysis and a restricted variation of structuralist linguistics. Despite the obvious advantages – with regard to style – of "pragmatic"approaches to language, such pragmatism merely returns to rule-determination in the guise of "normativity." Although style by definition resists any kind of rule-determination – whether posed in terms of semantics or intersubjective regulations of speech-acts – there can be no consideration of language that ignores the persistence of style in natural language. In terms of cognition, any discursive agent understands more than allowed by either semantics or speech-act theory. I ascribe this element of excessive signification to the role of style. My principal thesis is twofold: (1) a hermeneutic approach (exemplified by Schleiermacher) to literature should reveal the heuristically decisive role played by style in philosophy; and, more radically still, (2) style, in fact, may be crucially determinative of philosophical discourse in general. I suggest that a closer scrutiny of the lesser-known works of Ludwig Wittgenstein, conventionally regarded as having dreamt of a "philosophy without style," may consolidate the restoration of style's philosophical import.     

Chaos Theology: A New Approach to the Science-Theology Dialogue

Comparison of the concepts of creation from chaos and creation out of nothing ( creatio ex nihilo ) leads me to reject the latter for several reasons: it is not the biblical concept, and it presents serious conceptual, scientific, and theological problems. Chaos theology is outlined under the headings creation from chaos; chaos and contingency; chaos, evil, and creativity; chaos and incarnation; chaos and eschatology. It is shown to be well suited for the science-theology dialogue by some examples of its application to aspects of cosmic and biological evolution: initial mystery, separation and ordering; chaos and entropy; contingency and fine-tuning of the universe; purpose and progressiveness in evolution; and complexity theory and chaos events.     

Life-Prolonging Killings and their Relevance to Ethics

What makes killing morally wrong? And what makes killing morally worse than letting die? Standard answers to these two questions presuppose that killing someone involves shortening that person's life. Yet, as I argue in the first two sections of this article, this presupposition is false: Life-prolonging killings are conceivable. In the last two sections of the article, I explore the significance of the conceivability of such killings for various discussions of the two questions just mentioned. In particular, I show why the conceivability of life-prolonging killings renders Frances M. Kamm's attempt to provide an answer to the second question problematic.

Criterion-related construct validity

Established results on latent variable models are applied to the study of the validity of a psychological test. When the test predicts a criterion by measuring a unidimensional latent construct, not only must the total score predict the criterion, but the joint distribution of criterion scores and item responses must exhibit a certain pattern. The presence of this population pattern may be tested with sample data using the stratified Wilcoxon rank sum test. Often, criterion information is available only for selected examinees, for instance, those who are admitted or hired. Three cases are discussed: (i) selection at random, (ii) selection based on the current test, and (iii) selection based on other measures of the latent construct. Discriminant validity is also discussed.This work was supported in part by Grant SES-87-01890 from the Measurement Methods and Data Improvement Program of the U.S. National Science Foundation.
