C. Stephen Evans explains and defends Kierkegaard's account of moral obligations as rooted in God's commands, the fundamental command being `You shall love your neighbour as yourself'. The work will be of interest not only to those interested in Kierkegaard, but also to those interested in the relation between ethics and religion, especially questions about whether morality can or must have a religious foundation. As well as providing a comprehensive reading of Kierkegaard as an ethical thinker, Evans (...) puts him into conversation with contemporary moral theorists. Kierkegaard's divine command theory is shown to be an account that safeguards human flourishing, as well as protecting the proper relations between religion and state in a pluralistic society.

Dienes' & Perner's proposals are discussed in relation to the distinction between explicit and implicit systems of thinking. Evans and Over (1996) propose that explicit processing resources are required for hypothetical thinking, in which mental models of possible world states are constructed. Such thinking requires representations in which the individuals' propositional attitudes including relevant beliefs and goals are made fully explicit.
The images from wars in the Middle East that haunt us are those of young women killing and torturing. Their media circulated stories share a sense of shock. They have both galvanized and confounded debates over feminism and women's equality. And, as Oliver argues in this essay, they share, perhaps subliminally, the problematic notion of women as both offensive and defensive weapons of war, a notion that is symptomatic of fears of women's "mysterious" powers.
In the post-Newtonian world motion is assumed to be a simple category which relates to the locomotion of bodies in space, and is usually associated only with physics. Philosophy, God and Motion shows that this is a relatively recent understanding of motion and that prior to the scientific revolution motion was a much broader and more mysterious category, applying to moral as well as physical movements. SimonOliver presents fresh interpretations of key figures in the history of western (...) thought including Plato, Aristotle, Aquinas and Newton, examining the thinkers' handling of the concept of motion. Through close readings of seminal texts in ancient and medieval cosmology and early modern natural philosophy, the book moves from antique to modern times investigating how motion has been of great significance within theology, philosophy and science. Particularly important is the relation between motion and God, following Aristotle traditional doctrines of God have understood the divine as the 'unmoved mover' while post-Holocaust theologians have suggested that in order to be compassionate God must undergo the motion of suffering. Philosophy, God and Motion suggests that there may be an authentically theological, as well as a natural scientific understanding of motion. (shrink)
In Womanizing Nietzsche, Kelly Oliver uses an analysis of the position of woman in Nietzsche's texts to open onto the larger question of philosophy's relation to the feminine and the maternal. Offering readings from Nietzsche, Derrida, Irigaray, Kristeva, Freud and Lacan, Oliver builds an innovative foundation for an ontology of intersubjective relationships that suggests a new approach to ethics. Oliver argues that while Freud, Nietzsche and Derrida, in particular, attempt to open up philosophy to its other--the unconscious, (...) the body, difference, even the feminine--their attempts depend on closing off the possibility of a specifically feminine other. In this regard, Oliver maintains that none of these theorists have escaped the Hegelian model of intersubjectivity at the level of Lordship and Bondage. She suggests that the recent talk of the death of philosophy is a symptom of the exclusion of woman, the feminine and the maternal. By problematizing and reformulating the traditional philosophical association between the maternal and nature, Oliver presents an alternative model for intersubjectivity and ethics. (shrink)
'IF' is one of the most important and interesting words in the English language, being used to express hypothetical thought. The use of conditionals such as 'if' also distinguishes human intelligence from that of all other animals. In this volume, Jonathan Evans and David Over present a new theoretical approach to understanding hypothetical thought. The book draws on studies from the psychology of judgement and decision making, as well as philosophical logic.
Was love invented by European poets in the middle ages, as C. S. Lewis claimed, or is it part of human nature? Will winning the lottery really make you happy? Is it possible to build robots that have feelings? These are just some of the intriguing questions explored in this new guide to the latest thinking about the emotions. Drawing on a wide range of scientific research, from anthropology and psychology to neuroscience and artificial intelligence, Emotion: The Science of Sentiment (...) takes the reader on a fascinating journey into the human heart. Illustrating his points with entertaining examples from fiction, film, and popular culture, Dylan Evans ranges from the evolution of the emotions to the nature of love and happiness to the language of feelings, offering readers the most recent thinking on real life topics that touch us all. But Emotion is also a book filled with surprises. Readers will discover, for instance, that the basic emotions are felt the world over--whether we live in the shadow of Times Square or in the depths of the rain forest, we all feel the emotions of disgust, joy, surprise, anger, fear, and distress. We find out that, according to research, winning the lottery does not cause a lasting increase in happiness--a short-lived euphoria is followed in almost every case with a return to our usual emotional state, if not worse. And we meet Kismet, an MIT robot that can express a wide range of emotions, from fear to happiness. Fun to read and based on the latest scientific thinking, here is a stimulating look at our emotions. (shrink)

Turning Images in Philosophy, Science, and Religion: A New Book of Nature brings together new essays addressing the role of images and imagination recruited in the perennial debates surrounding nature, mind, and God. -/- The debate between "new atheists" and religious apologists today is often hostile. This book sets a new tone by locating the debate between theism and naturalism (most "new atheists" are self-described "naturalists") in the broader context of reflection on imagination and aesthetics. The eleven essays will be (...) of interest to anyone who is fascinated by the power of imagination and the role of aesthetics in deciding between worldviews or philosophies of nature. Representing a variety of points of view, authors include outstanding philosophers of religion and of science, a distinguished art historian, and a visual artist. -/- The book begins with Martin Kemp's essay on the work of the biologist, mathematician and classical scholar D'Arcy Wentworth Thompson in which Kemp develops the idea of "structural intuitions and a critique of reductive thinking about the natural world. This is followed by Geoffrey Gorham's overview and analysis of images of nature and God found in early modern science and philosophy. Anthony O'Hear questions a reductive, naturalist account of the origin of mind and values. Dale Jacquette offers a thoroughgoing naturalistic philosophy of the emergence of intentionality and a unique argument about the emergence of art and the aesthetic appreciation of nature. E.J. Lowe brings to light some challenges facing naturalistic approaches to human imaginative sensibility. Douglas Hedley articulates and defends a cognitive account of imagination, highlighting some of the difficulties confronting naturalism. Daniel N. Robinson offers a sweeping treatment of nature and naturalism, historically engaging Aristotle, Kant, Hegel and others. Conor Cunningham provides an aggressive critique of contemporary naturalism. Gordon Graham investigates the resources of naturalism in accounting for our sense of the sacred. Mark Wynn provides a subtle understanding of imagination and perception, suggesting how these may play into the theism - naturalism debate. The book concludes with Jil Evans' reflections on how images of the Galapagos Islands have been employed philosophically to picture either a naturalist or theistic image of nature. (shrink)
This enterprising book, written in the spirit of William James, urges our appreciation of the intensely personal character of spiritual transcendence. Phil Oliver's work has important implications for specialists concerned with the Jamesian concept of "pure experience," and it illuminates significant interdisciplinary ties among philosophy, literature, and other intellectual domains.
This authoritative and lively exploration of the theories of contemporary feminism covers all the major variants of feminist political thought from the "traditional" schools of the women's movement-particularly radical, liberal, and socialist-to today's postmodern texts. Feminist Theory Today examines the epistemological challenge from critical legal theory and postmodernist thought; the divergences within, as well as between, feminist schools; and the protests from women marginalized by the feminist movement, including those who are lesbian and those who are black. It also interrogates (...) the dialectic equality and difference and reconceptualizes this pervasive tenet of feminist thought. Author Judith Evans documents the changes in socialist feminism from its revolutionary origins to its current focus on modifying liberal democratic forms. Students and teachers of women's studies, sociology, and political theory will find this an authoritative and lively exploration of the theories of contemporary feminism. It is also essential reading for anyone seeking to understand why the women's movement is as it is today. (shrink)

The idea that intuition plays a basic role in moral knowledge and moral philosophy probably began in the eighteenth century. British philosophers such as Anthony Shaftsbury, Francis Hutcheson, Thomas Reid, and later David Hume talk about a “moral sense” that they place in John Locke’s theory of knowledge in terms of Lockean reflexive perceptions, while Richard Price seeks a faculty by which we obtain our ideas of right and wrong. In (...) the twentieth century intuitionism in moral philosophy was revived by the works of G. E. Moore, H. A. Prichard, and W. D. Ross. These philosophers reject Kantian deontological ethics and utilitarianism insisting that intuition is the only source of moral knowledge. Recently, there is a renewed interest in intuition by philosophers doing meta-philosophy by reflecting on what philosophers do, and why they disagree. In this essay we plan to take some of this recent literature on intuition and apply it to moral philosophy. We will proceed by (1) defining a conception of intuition, (2) answering some skeptical challenges, (3) delimiting its target, and (4) arguing that intuition is often a source of moral knowledge.

In this paper, I show that the question of how dual process theories of reasoning and judgement account for conflict between System 1 (heuristic) and System 2 (analytic) processes needs to be explicated and addressed in future research work. I demonstrate that a simple additive probability model that describes such conflict can be mapped on to three different cognitive models. The pre-emptive conflict resolution model assumes that a decision is made at the outset as to whether a heuristic or analytic (...) process will control the response. The parallel-competitive model assumes that each system operates in parallel to deliver a putative response, resulting sometimes in conflict that then needs to be resolved. Finally, the default-interventionist model involves the cueing of default responses by the heuristic system that may or may not be altered by subsequent intervention of the analytic system. A second, independent issue also emerges from this discussion. The superior performance of higher-ability participants on reasoning tasks may be due to the fact that they engage in more analytic reasoning ( quantity hypothesis ) or alternatively to the fact that the analytic reasoning they apply is more effective ( quality hypothesis ).

Yah boo sucks to the grammer wot we lernt in skool! Grammar (and the bad old traditional logic) says that quantifier phrases such as 'nobody', 'everyone', 'all women', 'some men' and 'a man' are in the same category as names such as 'Milly', 'Molly' and 'Mandy'. So, prior to their first corrective lessons, students are awfully muddled, the first and fundamental problem being the Woozle hunt for somebody called 'nobody'. Hoorah for modern logic and logic teachers! The story used to (...) justify our current logics is entirely fictional. The claims about names and quantifier phrases in English are wildly false. Two of the heroes of modern logic, Russell and Hilbert, make the very mistakes which are falsely blamed on traditional logic. The villain, Meinong, turns out to have been working a different patch. Ideas ascribed to traditional grammar are modern inventions. Neither logicians nor grammarians can be trusted to tell the history of either grammar or logic. (shrink)
Genealogy is a critical method employed most notably by Friedrich Nietzsche and Michel Foucault. Although he does not explicitly acknowledge it, Mikhail Bakhtin, the Russian linguist and philosopher of language, also uses this method. I examine the way these three thinkers construe both the critical and the affirmative roles of genealogy. The 'affirmative role' refers to what genealogy itself valorizes in exposing the limits of the universal claims it critiques. I identify three tasks of the critical role of genealogy and (...) explore what I feel are two limitations of its affirmative side: the anonymity of Nietzsche's 'eternal return of the same' and the indeterminacy of Foucault's 'undefined work of freedom'. I argue that a judicious use of Bakhtin's notions of 'voice' and 'dialogized heteroglossia' can help genealogy to overcome these two limitations without resurrecting the totalizing systems of thought that all three thinkers repudiate. Key Words: Bakhtinian 'voice' Friedrich Nietzsche genealogy 'heteroglossia' Michel Foucault Mikhail Bakhtin multi-voiced body power resistance will-to-power. (shrink)
Both Nietzsche and Merleau-Ponty repudiate the mirror view of perception and embrace what Nietzsche refers to as solar love or creative perception. I argue that Merleau-Ponty thinks of this type of perception primarily in terms of convergence and Nietzsche in terms of divergence. I then show how, contrary to their own emphases, Merleau-Ponty's notion of flesh and Nietzsche's idea of chaos suggest that convergence and divergence are abstractions from an ontologically prior realm of hybrid perceptions. In this realm, each perception (...) is shot through with the others, simultaneously inside and outside one another. The creative tension among these perceptions continually produces new perspectives or voices, that is, a realm whose very being is metamorphosis. Moreover, this realm of hybrid perceptions suggests a political principle that might prove attractive for communities in an age of diversity and cultural hybridity. (shrink)
We present a plural logic that is as expressively strong as it can be without sacrificing axiomatisability, axiomatise it, and use it to chart the expressive limits set by axiomatisability. To the standard apparatus of quantification using singular variables our object-language adds plural variables, a predicate expressing inclusion (is/are/is one of/are among), and a plural definite description operator. Axiomatisability demands that plural variables only occur free, but they have a surprisingly important role. Plural description is not eliminable in favour of (...) quantification; on the contrary, quantification is definable in terms of it. Predicates and functors (function signs) can take plural as well as singular terms as arguments, and both many-valued and single-valued functions are expressible. The system accommodates collective as well as distributive predicates, and the condition for a predicate to be distributive is definable within it; similarly for functors. An essential part of the project is to demonstrate the soundness and completeness of the calculus with respect to a semantics that does without set-theoretic domains and in which the use of set-theoretic extensions of predicates and functors is replaced by the sui generis relations and functions for which the extensions were at best artificial surrogates. Our metalanguage is designed to solve the difficulties involved in talking plurally about individuals and about the semantic values of plural items. (shrink)
The history of the idea of predicate is the history of its emancipation. The lesson of this paper is that there are two more steps to take. The first is to recognize that predicates need not have a fixed degree, the second that they can combine with plural terms. We begin by articulating the notion of a multigrade predicate: one that takes variably many arguments. We counter objections to the very idea posed by Peirce, Dummett's Frege, and Strawson. We show (...) that the arguments of a multigrade predicate must be grouped into places, with perhaps several arguments occupying positions at a place. Variability may relate to places or positions. Russell's multiple judgement predicate turns out to be just one example of a family—‘is necessarily true of’, ‘is said of’, ‘is instantiated by’ and so on—of predicates with variably many places. Our main concern, however, is lists. Any adequate account of lists must include plural as well as singular terms. On one account, lists are mere strings of separate arguments, which occupy variably many positions within a place of a multigrade predicate. A quite different account takes the list itself to be a compound plural term. We compare these rival conceptions, and reach some surprising conclusions. As a coda, we deploy the conceptual apparatus developed in the paper to assess Morton's pioneer system of multigrade logic. (shrink)
Carruthers’proposals would seem to implicate language in what is known as System 2 thinking (explicit) rather than System 1 thinking (implicit) in contemporary dual process theories of thinking and reasoning. We provide outline description of these theories and show that while Carruthers’characterization of non-verbal processes as domain-specific identifies one critical feature of System 1 thinking, he appears to overlook the fact that much cognition of this type results from domain-general learning processes. We also review cognitive psychological evidence that shows that (...) language and the explicit representations it supports are heavily involved in supporting System 1 thinking, but falls short of supporting his claim that it is the medium in which domain-general thinking occurs.

In this study, we examine the belief bias effect in syllogistic reasoning under both standard presentation and in a condition where participants are required to respond within 10 seconds. As predicted, the requirement for rapid responding increased the amount of belief bias observed on the task and reduced the number of logically correct decisions, both effects being substantial and statistically significant. These findings were predicted by the dual-process account of reasoning, which posits that fast heuristic processes, responsible for belief bias, (...) compete with slower analytic processes that can lead to correct logical decisions. Requiring rapid responding thus differentially inhibits the operation of analytic reasoning processes, leading to the results observed. (shrink)
Many philosophers and psychologists now argue that emotions play a vital role in reasoning. This paper explores one particular way of elucidating how emotions help reason which may be dubbed ?the search hypothesis of emotion?. After outlining the search hypothesis of emotion and dispensing with a red herring that has marred previous statements of the hypothesis, I discuss two alternative readings of the search hypothesis. It is argued that the search hypothesis must be construed as an account of what emotions (...) typically do, rather than as a definition of emotion. Even as an account of what emotions typically do, the search hypothesis can only be evaluated in the context of a specific theory of what emotions are. 1 Introduction 2 The search hypothesis of emotion 3 A red herring: the frame problem 4 The search problem 5 Two readings of the search hypothesis 6 Two final remarks 7 Conclusion.

The two main psychological theories of the ordinary conditional were designed to account for inferences made from assumptions, but few premises in everyday life can be simply assumed true. Useful premises usually have a probability that is less than certainty. But what is the probability of the ordinary conditional and how is it determined? We argue that people use a two stage Ramsey test that we specify to make probability judgements about indicative conditionals in natural language, and we describe experiments (...) that support this conclusion. Our account can explain why most people give the conditional probability as the probability of the conditional, but also why some give the conjunctive probability. We discuss how our psychological work is related to the analysis of ordinary indicative conditionals in philosophical logic. (shrink)
Russell had two theories of definite descriptions: one for singular descriptions, another for plural descriptions. We chart its development, in which ‘On Denoting’ plays a part but not the part one might expect, before explaining why it eventually fails. We go on to consider many-valued functions, since they too bring in plural terms—terms such as ‘4’ or the descriptive ‘the inhabitants of London’ which, like plain plural descriptions, stand for more than one thing. Logicians need to take plural reference seriously (...) if only because mathematicians take many-valued functions seriously. We assess the objection (by Russell, Frege and others) that many-valued functions are illegitimate because the corresponding terms are ambiguous. We also assess the various methods proposed for getting rid of them. Finding the objection ill-founded and the methods ineffective, we introduce a logical framework that admits plural reference, and use it to answer some earlier questions and to raise some more.

Three experiments investigated the effect of rarity on people's selection and interpretation of data in a variant of the pseudodiagnosticity task. For familiar (Experiment 1) but not for arbitrary (Experiment 3) materials, participants were more likely to select evidence so as to complete a likelihood ratio when the initial evidence they received was a single likelihood concerning a rare feature. This rarity effect with familiar materials was replicated in Experiment 2 where it was shown that participants were relatively insensitive to (...) explicit manipulations of the likely diagnosticity of rare evidence. In contrast to the effects for data selection, there was an effect of rarity on confidence ratings after receipt of a single likelihood for arbitrary but not for familiar materials. It is suggested that selecting diagnostic evidence necessitates explicit consideration of the alternative hypothesis and that consideration of the possible consequences of the evidence for the alternative weakens the rarity effect in confidence ratings. Paradoxically, although rarity effects in evidence selection and confidence ratings are in the spirit of Bayesian reasoning, the effect on confidence ratings appears to rely on participants thinking less about the alternative hypothesis.

: Our stereotypes of maternity and paternity as manifest in the history of philosophy and psychoanalysis interfere with the ability to imagine loving relationships. The associations of maternity with antisocial nature and paternity with disembodied cul-ture are inadequate to set up primary love relationships. Analyzing the conflicts in these associations, I reformulate the maternal body as social and lawful, and I re-formulate the paternal function as embodied, which enables imagining our primary relationships as loving.
In this article I explore the underlying political philosophy of public bioethics by comparing it to technocratic authority, particularly the technocratic authority claimed by economists in Mexico in the 1980s and 1990s. I find that public bioethics - at least in the dominant forms - is implicitly designed for and tries to use technocratic authority. I examine how this type of bioethics emerged and has continued. I finish by arguing that, as claims to technocratic authority go, bioethics is in an (...) incredibly weak position, which partly explains why it has never gained the degree of public legitimacy that other technocracies have gained. I conclude by arguing for a "technocracy-lite" orientation for public bioethics. (shrink)
In the past few decades, research in the psychology of emotion has benefited greatly from being located in a firm evolutionary framework. It is argued that research in the psychology of mood might attain equal rigour by taking a similar approach. An evolutionary framework for mood research would be based on evolutionary psychology, the main thesis of which is the Massive Modularity Hypothesis. Translating the folk-psychological language of moods into the scientific language of modules might clarify many theoretical questions and (...) provide a sound basis for empirical research. It is argued that such an evolutionary approach would reveal mood to be a much more heterogeneous category than emotion. While the six basic emotions identified by Paul Ekman are probably each subserved by a single module, prototypical moods such as elation, depression, anxiety and irritability are likely to be subserved by a wide range of modules. An evolutionary approach to mood might therefore lead to the elimination of the concept of mood from scientific psychology altogether. (shrink)
In the Philebus Plato argues that every rational human being, given the choice, will prefer a life that is moderately thoughtful and moderately pleasant to a life that is utterly thoughtless or utterly pleasureless. This is true, he thinks, even if the thoughtless life at issue is intensely pleasant and the pleasureless life at issue is intensely thoughtful. Evidently Plato wants this argument to show that neither pleasure nor thought, taken by itself, is sufficient to make a life choiceworthy for (...) us. But there is some disagreement among commentators about whether or not he also wants the argument to show why. Is the argument designed to establish that we should reject thoughtless and pleasureless lives because some pleasures and some thoughts are goods? Or is it silent on this issue? Many interpreters take the first option, claiming that Plato uses the argument to attack both the hedonist view that only pleasures are goods and the intellectualist view that only thoughts are goods. My aim in this paper is to show that the second option is at least as attractive as the first, both exegetically and philosophically. (shrink)
The aim of the present research was to develop a difficulty model for logical reasoning problems involving complex ordered arrays used in the Graduate Record Examination. The approach used involved breaking down the problems into their basic cognitive elements such as the complexity of the rules used, the number of mental models required to represent the problem, and question type. Weightings for these different elements were derived from two experimental studies and from the reasoning literature. Based on these weights, difficulty (...) models were developed which were then tested against new data. The models had excellent predictive validity and showed the relative influence of rule based factors and factors relating to the number of underlying models. Different difficulty models were needed for different question types, suggesting that people used a variety of approaches and, at a wider level, that both mental models and mental rules may be used in reasoning.

: What is truly beautiful? For Søren Kierkegaard the beautiful is to be found in an integrated self, one that is freely chosen. This article explores Kierkegaard's "aesthetic" stage of existence through the character of Augusto Pérez, the protagonist of Miguel de Unamuno's novel, Niebla. After establishing a solid link between Unamuno and Kierkegaard, Kierkegaard's "ethical" stage is used to critique the "aesthetic" stage on aesthetic grounds, on the basis of the beauty found in life's work, a calling. The conclusion (...) is that the sphere of the "aesthetic" does not achieve Kierkegaard's "aesthetics" of an integrated, fully existing self. (shrink)
Carter and Leslie's Doomsday Argument maintains that reflection upon the number of humans born thus far, when that number is viewed as having been uniformly randomly selected from amongst all humans, past, present and future, leads to a dramatic rise in the probability of an early end to the human experiment. We examine the Bayesian structure of the Argument and find that the drama is largely due to its oversimplification.
: I begin to suggest an alternative to the notion of vision based in alienation and hostility put forth by Jean-Paul Sartre, Sigmund Freud, and Jacques Lacan. I diagnose this alienating vision as a result of a particular alienating notion of space presupposed by their theories. I develop Irigaray's comments about light and air to suggest an alternative notion of space that opens up the possibility that vision connects us to others rather than alienates us from them.
By concentrating on abortion, the culture wars have avoided facing a crisis about the end of life. This paper explores four themes: (1) the technological transformation of birth and death into matters of decision, not matters of fact; (2) abortion as the nexus of Eros (sex) with Thanatos (death); (3) the real crisis, conveniently masked by our obsession with sex, looming at the end of life, not at its beginning; (4) the surplus-repression that protects us from assuming responsibility for choosing (...) between life and death.

The Fitzgerald-Lorentz contraction hypothesis, proposed as an explanation of the Michelson-Morley result, fails to account for the Kennedy-Thorndike result. Hence, Grünbaum argues, the hypothesis has been falsified. However, the contraction hypothesis as formulated by Lorentz is false for the very fundamental reason that it entails a contradiction, namely, the consequence that light waves must have a variable velocity along what by definition is taken to be a rest length. Furthermore, the attempt to resolve this contradiction by coupling the Fitzgerald-Lorentz contraction (...) with the hypothesis that clock rates are a function of velocity, is open to a sound, methodological objection. The Michelson-Morley result is fully satisfied, provided only that the lengths of the interferometer arms, in the longitudinal and transverse positions, are thought to be related to one another in a certain ratio, and this ratio may be interpreted as a contraction in both arms. Since this twofold contraction hypothesis suffices to explain both the Michelson-Morley and the Kennedy-Thorndike results, and since it entails no contradiction, there is no need to correct both the length of rods and the rate of clocks. Therefore, the combined clock-rod hypothesis, and with it the Fitzgerald-Lorentz contraction hypothesis, must be rejected. (shrink)
In this paper we argue that it is often adaptive to use one's background beliefs when interpreting information that, from a normative point of view, is incomplete. In both of the experiments reported here participants were presented with an item possessing two features and were asked to judge, in the light of some evidence concerning the features, to which of two categories it was more likely that the item belonged. It was found that when participants received evidence relevant to (...) just one of these hypothesised categories (i.e. evidence that did not form a Bayesian likelihood ratio) they used their background beliefs to interpret this information. In Experiment 2, on the other hand, participants behaved in a broadly Bayesian manner when the evidence they received constituted a completed likelihood ratio. We discuss the circumstances under which participants, when making their judgements, consider the alternative hypothesis. We conclude with a discussion of the implications of our results for an understanding of hypothesis testing, belief revision, and categorisation. (shrink)
What is the nature of the decision-related personal values of corporate management? Managers' attitudes and behaviors are built upon their personal value systems (PVS). Knowledge about the structure of management's PVS assists in understanding the attributes of corporate decision making. Utilizing a survey instrument developed and used by England (1967, 1975), this article updates this research into corporate managers' personal value systems. England's PVS consists of sixty-six pre-tested values clustered into five groups. As one could expect with personal values, statistical (...) tests reveal that even with dramatic changes in the business environment the overall personal values structure has not changed over the intervening three decades. The results also reveal that corporate managers retain their pragmatic value orientation as discussed by England. (shrink)
Williams argues that humans have evolved special purpose adaptations for eliciting medical attention from others, such as a specific facial expression of pain. She also recognises that such adaptations would almost certainly have coevolved with adaptations for providing and responding to medical care. The placebo response may be one such adaptation, and any evolutionary account of pain must also address this important phenomenon.
Medicine, as Byron Good argues, reconstitutes thehuman body of our daily experience as a medical body,unfamiliar outside medicine. This reconstitution can be seen intwo ways: (i) as a salutary reminder of the extent to which thereality even of the human body is constructed; and (ii) as anarena for what Stephen Toulmin distinguishes as theintersection of natural science and history, in which many ofphilosophy''s traditional (and traditionally abstract) questionsare given concrete and urgent form.This paper begins by examining a number of dualities (...) between themedical body and the body familiar in daily experience. Toulmin''s epistemological analysis of clinical medicine ascombining both universal and existential knowledge is thenconsidered. Their expression, in terms of attention,respectively, to natural science and to personal history, isexplored through the epistemological contrasts between themedical body and the familiar body, noting the traditionalphilosophical questions which they in turn illustrate.

We report the results of three experiments designed to assess the role of suppositions in human reasoning. Theories of reasoning based on formal rules propose that the ability to make suppositions is central to deductive reasoning. Our first experiment compared two types of problem that could be solved by a suppositional strategy. Our results showed no difference in difficulty between problems requiring affirmative or negative suppositions and very low logical solution rates throughout. Further analysis of the error data showed a (...) pattern of responses, which suggested that participants reason from a superficial representation of the premises in these arguments and this drives their choice of conclusion. Our second experiment employed a different set of suppositional problems but with extremely similar proofs in terms of the rules applied and number of inferential steps required. As predicted by our interpretation of reasoning strategies employed in Experiment 1, logical performance was very much higher on these problems. Our third experiment showed that problems that could be solved by constructing an initial representation of the premises were easier than problems in which this representation was not sufficient. This effect was independent of the suppositional structure of the problems. We discuss the implications of this research for theories of reasoning based on mental models and inference rules. (shrink)
