By means of an example, shows the possibility of beliefs that are separately rational whilst together inconsistent.

We explore ways in which purely qualitative belief change in the AGM tradition throws light on options in the treatment of conditional probability. First, by helping see why it can be useful to go beyond the ratio rule defining conditional from one-place probability. Second, by clarifying what is at stake in different ways of doing that. Third, by suggesting novel forms of conditional probability corresponding to familiar variants of qualitative belief change, and conversely. Likewise, we explain how recent work on (...) the qualitative part of probabilistic inference leads to a very broad class of 'proto-probability' functions. (shrink)

While environmental claims are increasingly used by companies to appeal consumers, they also attract greater scrutiny from independent parties interested in consumer protection. Consumers are now able to compare corporate environmental claims against external, often disconfirming, information to form their brand attitudes and purchase intentions. What remains unclear is how the level of information specificity of both the environmental claims and external disconfirming information interact to influence consumer reactions. Two experiments address this gap in the CSR communication literature. When specific (...) claims are countered by specific external information, consumers report more negative brand attitudes and lower purchase intentions. The effect is serially mediated by skepticism toward the claims and lack of corporate credibility. We conclude by discussing strategies that firms can utilize to avoid information dilution and ensure that external disconfirming information percolates to consumers as specific. (shrink)

The organism is one of the fundamental concepts of biology and has been at the center of many discussions about biological individuality, yet what exactly it is can be confusing. The definition that we find generally useful is that an organism is a unit in which all the subunits have evolved to be highly cooperative, with very little conflict. We focus on how often organisms evolve from two or more formerly independent organisms. Two canonical transitions of this type—replicators clustered in (...) cells and endosymbiotic organelles within host cells—demonstrate the reality of this kind of evolutionary transition and suggest conditions that can favor it. These conditions include co-transmission of the partners across generations and rules that strongly regulate and limit conflict, such as a fair meiosis. Recently, much attention has been given to associations of animals with microbes involved in their nutrition. These range from tight endosymbiotic associations like those between aphids and Buchnera bacteria, to the complex communities in animal intestines. Here, starting with a reflection about identity through time, we consider the distinctions between these kinds of animal–bacteria interactions and describe the criteria by which a few can be considered jointly organismal but most cannot.

"Dr. Rubin has brought cognitive psychology into a wholly unprecedented dialogue with studies in oral tradition. The result is a truly new perspective on memory and the processes of oral tradition." --John Miles Foley, University of Missouri.

The article offers an approach to inquiry about, the foundation of medical ethics by addressing three areas of conceptual presupposition basic to medical ethical theory. First, medical ethics must presuppose a view about the nature of medicine. it is argued that the view required by a cogent medical morality entails that medicine be seen both as a healing relationship and as a practical art. Three ways in which medicine inherently involves values and valuation are presented as important, i.e., in being (...) aimed at the good of health, in being a cognitive art evaluating towards that good, and as a manifestation of a virtuous disposition concerning that good. Finally, a value ontology drawn from these considerations is seen as necessarily underlying medical ethics. A set of three such basic values are promoted as crucial: the value of health; the value of the individual patient; and the value of altruism that mediates the class of potential patients. (shrink)

In this article 1 I have two theological interests and a less direct philosophical one.

Considerable debate has occurred about the proper role of philosophers when offering ethics consultations. Some argue that only physicians or clinical experienced personnel should offer ethics consultations in the clinical setting. Others argue still further that philosophers are ill-equipped to offer such advice, since to do so rests on no social warrant, and violates the abstract and neutral nature of the discipline itself.I argue that philosophers not only can offer such consultations but ought to. To be a bystander when one's (...) discipline does offer insights and methods of value discernment is pusillanimous. But this position requires a view of clinical medical ethics as one that arises out of the clinical practice of medicine, and not just from an application of general ethical principles to the practice of medicine. I conclude with some skills that trained philosophers can bring to the consultation service, and note that all consultations are in the form of recommendations that the patient, family, and physician are still free to accept or reject. Philosophers in the clinical setting do not make decisions. (shrink)

The sciences use a wide range of visual devices, practices, and imaging technologies. This diversity points to an important repertoire of visual methods that scientists use to adapt representations to meet the varied demands that their work places on cognitive processes. This paper identifies key features of the use of visualization in a range of scientific domains and considers the implications of this repertoire for understanding scientists as cognitive agents.

Despite its long tradition in social psychology, we consider that Cognitive Dissonance Theory presents serious flaws concerning its methodology which question the relevance of the theory, limit breakthroughs, and hinder the evaluation of its core hypotheses. In our opinion, these issues are mainly due to operational and methodological weaknesses that have not been sufficiently addressed since the beginnings of the theory. We start by reviewing the ambiguities concerning the definition and conceptualization of the term cognitive dissonance. We then review the (...) ways it has been operationalized and we present the shortcomings of the actual paradigms. To acquire a better understanding of the theory, we advocate a stronger focus on the nature and consequences of the cognitive dissonance state itself. Next, we emphasize the actual lack of standardization, both in the ways to induce cognitive dissonance and to assess it, which impairs the comparability of the results. Last, in addition to reviewing these limits, we suggest new ways to improve the methodology and we conclude on the importance for the field of psychology to take advantage of these important challenges to go forwards.

To provide the three-way comparisons needed to test existing theories, we compared (1) most-stressful memories to other memories and (2) involuntary to voluntary memories (3) in 75 community dwelling adults with and 42 without a current diagnosis of posttraumatic stress disorder (PTSD). Each rated their three most-stressful, three most-positive, seven most-important and 15 word-cued autobiographical memories, and completed tests of personality and mood. Involuntary memories were then recorded and rated as they occurred for 2 weeks. Standard mechanisms of cognition and (...) affect applied to extreme events accounted for the properties of stressful memories. Involuntary memories had greater emotional intensity than voluntary memories, but were not more frequently related to traumatic events. The emotional intensity, rehearsal, and centrality to the life story of both voluntary and involuntary memories, rather than incoherence of voluntary traumatic memories and enhanced availability of involuntary traumatic memories, were the properties of autobiographical memories associated with PTSD.

This book, in language accessible to the general reader, investigates twelve of the most notorious, most interesting, and most instructive episodes involving the interaction between science and Christianity, aiming to tell each story in its historical specificity and local particularity. Among the events treated in When Science and Christianity Meet are the Galileo affair, the seventeenth-century clockwork universe, Noah's ark and flood in the development of natural history, struggles over Darwinian evolution, debates about the origin of the human species, and (...) the Scopes trial. Readers will be introduced to St. Augustine, Roger Bacon, Pope Urban VIII, Isaac Newton, Pierre-Simon de Laplace, Carl Linnaeus, Charles Darwin, T. H. Huxley, Sigmund Freud, and many other participants in the historical drama of science and Christianity. (shrink)

A position has been advanced by a number of philosophers, notably by Burnham and Skilleås, that certain knowledge is required to aesthetically appreciate a fine wine. They further argue that pleasure is not an integral part of aesthetically appreciating wine. Their position implies that a novice cannot aesthetically appreciate a fine wine. This paper draws on research into tasting and psychology to rebut these claims. I argue that there is strong evidence from both the average consumer and from wine experts (...) that they are unable to separate enjoyment from aesthetic evaluation; secondly, I argue that wine knowledge may actually preclude tasting of the wine as it exists in the glass due to perceptual bias. I conclude by arguing that it is unclear how exactly knowledge of things like terroir is supposed to affect the taste, as well as question what role conforming to a certain style plays in aesthetic success, as arguments that require knowledge for appreciation typically emphasize knowledge of styles of wine.

I offer a critical analysis of a view that has become a dominant aspect of recent thought on the relationship between evolution and morality, and propose an alternative. An ingredient in Michael Ruse's 'error theory' (Ruse 1995) is that belief in moral (prescriptive, universal, and nonsubjective) guidelines arose in humans because such belief results in the performance of adaptive cooperative behaviors. This statement relies on two particular connections: between ostensible and intentional types of altruism, and between intentional altruism and morality. (...) The latter connection is problematic because it makes morality redundant, its role having already been fulfilled by the psychological dispositions that constitute intentional altruism. Both behavioral ecology and moral psychology support this criticism, and neither human behavioral flexibility nor the self-regard / other-regard distinction can provide a defense of the error theory. I conclude that morality did not evolve to curb rampant selfishness; instead, the evolutionarily recent 'universal law' aspect of morality may function to update behavioral strategies which were adaptive in the paleolithic environment of our ancestors (to which our psychological dispositions are best adapted), by means of norms more appropriate to our novel social environment.

Testimonial injustice occurs when hearers attribute speakers a credibility deficit because of an identity prejudice and consequently dismiss speakers’ testimonial assertions. Various philosophers explain testimonial injustice by appealing to interpersonal norms arising within testimonial exchanges. When conversational participants violate these interpersonal norms, they generate second-personal epistemic harms, harming speakers as epistemic agents. This focus on testimony, however, neglects how systematically misevaluating speakers’ knowledge affects conversational participants more generally. When hearers systematically misevaluate speakers’ conversational competence because of entrenched assumptions about what (...) speakers know, I call these conversational epistemic injustices. I argue the same epistemic harm in testimonial injustice arises for non-assertoric speech acts, generating conversational epistemic injustices. For across speech acts, deflated knowledge attributions create second-personal harms that prevent speakers from using their knowledge in linguistic exchanges, limiting their epistemic agency. These harms however are not reducible to linguistic harms, (e.g.,) silencing or discursive injustice. This article applies insight from how second-personal epistemic harm arises in testimonial exchanges to conversational exchanges more generally, demonstrating that epistemic injustices arise beyond testimonial exchanges and contexts of inquiry because deflated knowledge attributions undermine general conversational norms requiring participants assume each other’s conversational competence, generating conversational epistemic injustices.

A discussion of the connections and differences between completeness and representation theorems in logic, with examples drawn from classical and modal logic, the logic of friendliness, and nonmonotonic reasoning.

Relevance logic is ordinarily seen as a subsystem of classical logic under the translation that replaces arrows by horseshoes. If, however, we consider the arrow as an additional connective alongside the horseshoe, then another perspective emerges: the theses of relevance logic, specifically the system R, may also be seen as the output of a conservative extension of the relation of classical consequence. We describe two ways in which this may be done. One is by defining a suitable closure relation out (...) of the set of theses of relevance logic; the other is by adding to the usual natural deduction system for it further rules with ‘projective constraints’, whose application restricts the subsequent application of other rules. The significance of the two constructions is also discussed. (shrink)

Discusses the strong points and the limitations of Ajdukiewicz' approach to grammar.

I argue that thought experiments are a form of experimental reasoning similar to real experiments. They require the same ability to participate by following a narrative as real experiments do. Participation depends in turn on using what we already know to visualize, manipulate and understand what is unfamiliar or problematic. I defend the claim that visualization requires embodiment by an example which shows how tacit understanding of the properties of represented objects and relations enables us to work out how such (...) objects might behave in a postulated world. This knowledge is that of embodied agents. That thought experiments require embodied participation is what makes them experiments rather than arguments. Unlike real experiments, from which ordinary perception has been displaced by instrumentation, thought experiments still appeal to relatively unmediated common sense, even when their purpose is to criticize or subvert common sense notions.

Propositions about the nature of expertise, in general, and expertise in pedagogy, in particular, are discussed. The time needed to develop expertise in teaching and the highly contextual nature of teachers’ knowledge are also discussed. Four theories of teacher development are presented, with an elaboration on the heuristic value of the theory of Dreyfus and Dreyfus (1986). Examples from the pedagogical literature are used to illustrate this theory. The recent research establishing causal relationships between those identified as experts in teaching (...) and their students’ academic achievement is also presented. This research allows those who study expertise in teaching to have a more objective measure for identifying and studying expert pedagogues. (shrink)

According to Frankena, “the moral point of view is what Alison Wilde and Heather Badcock did not have.” Most of us, however, are not such extreme examples. We are capable of the moral point of view, but we fail to take the necessary time or make the required efforts. We resist pulling ourselves from other distractions to focus on the plight of others and what we might do to ameliorate their suffering. Perhaps compassion is rooted in understanding what it is (...) that connects us with others rather than what separates us, and rests on developing sufficient awareness, to internalize what our actions, or lack of them, mean in the lives of others.

Increasingly, the world seems to shrink due to our ever-expanding technological and communication capacities. Correspondingly, our awareness of other cultures increases. This is especially true in the field of bioethics because the technological progress of medicine throughout the world is causing dramatic and challenging intersections with traditionally held values. Think of the use of pregnancy monitoring technologies like ultrasound to abort fetuses of the “wrong” sex in India, the sale of human organs in and between countries, or the disjunction between (...) the haves and the have-nots in South America when it comes to bone marrow transplants, while thousands of other children die for want of fundamental goods and services like clean water, basic inoculations, and food itself.

Like most other sciences, behavior analysis adopts an assumption of uniformity, namely that principles discovered under controlled conditions apply outside the laboratory as well. Since the boundary between public and private depends on the vantage point of the observer, observability is not an inherent property of behavior. From this perspective, private events are assumed to enter into the same orderly relations as public behavior, and the distinction between public and private events is merely a practical one. Private events play no (...) role in the experimental analysis of behavior, but they permit us to make sense of many commonplace phenomena where controlled observation is impossible but unsystematic data are available. Such interpretive exercises serve both to guide research and to displace occult explanations. (shrink)

"Dr. Rubin has brought cognitive psychology into a wholly unprecedented dialogue with studies in oral tradition. The result is a truly new perspective on memory and the processes of oral tradition." --John Miles Foley, University of Missouri.

Case studies of diverse scientific fields show how scientists use a range of resources to generate new interpretative models and to establish their plausibility as explanations of a domain. They accomplish this by manipulating imagistic representations in particular ways. I show that scientists in different domains use the same basic transformations. Common features of these transformations indicate that general cognitive strategies of interpretation, simplification, elaboration, and argumentation are at work. Social and historical studies of science emphasize the diversity of local (...) contexts of practice. However, the existence of common strategies shows that this diversity masks an important repertoire of cognitive strategies. Scientists use this repertoire to adapt their representations to meet the cognitive demands of different contexts of practice. This paper considers the implications of this finding for the notion of scientists as cognitive agents in distributed knowledge-producing systems. (shrink)

In June 1993, conjoined twins Amy and Angela Lakeberg became the focus of national attention. They shared a complex six‐chambered heart and one liver; only one could survive separation surgery, and even her chances were slim. The medical challenge was great and the ethical challenges were even greater.
