The cognitive science of science studies the cognitive processes involved in carrying out science: How do scientists reason? How do scientists develop new theories? How do scientists deal with data that are inconsistent with their theories? How do scientists choose between competing theories? Research on these issues has been carried out by investigators in a number of cognitive science disciplines, particularly psychology, philosophy, and artificial intelligence. More detailed accounts of work in this area can be found in two recent conference (...) volumes. (shrink)

In this paper we provide a psychological account of the nature and development of explanation. We propose that an explanation is an account that provides a conceptual framework for a phenomenon that leads to a feeling of understanding in the reader/hearer. The explanatory conceptual framework goes beyond the original phenomenon, integrates diverse aspects of the world, and shows how the original phenomenon follows from the framework. We propose that explanations in everyday life are judged on the criteria of empirical accuracy, (...) scope, consistency, simplicity, and plausibility. We conclude that explanations in science are evaluated by the same criteria, plus those of precision, formalisms, and fruitfulness. We discuss several types of explanation that are used in everyday life – causal/mechanical, functional, and intentional. We present evidence to show that young children produce explanations that have the same essential form as those used by adults. We also provide evidence that children use the same evaluation criteria as adults, but may not apply those additional criteria for the evaluation of explanations that are used by scientists.

This book is intended to help transform epistemology - the traditional study of knowledge - into a rigorous discipline by removing conceptual roadblocks and developing formal tools required for a fully naturalized epistemology. The evolutionary approach which Harms favours begins with the common observation that if our senses and reasoning were not reliable, then natural selection would have eliminated them long ago. The challenge for some time has been how to transform these informal musings about evolutionary epistemology into a rigorous (...) theoretical discipline capable of complementing current scientific studies of the evolution of cognition with a philosophically defensible account of meaning and justification.

Could a classical theist be a physicalist? Although a negative answer to this question may seem obvious, it turns out that a case can be made for the consistency of a variant of classical theism and global supervenience physicalism. Although intriguing, the case ultimately fails due to the weakness of global supervenience as an account of the dependence of mental on physical properties.

Various laws and theories in the natural and social sciences are presented with a view to discerning the syntactic and semantic characteristics of many idealizations in science. Three different kinds of idealizations are discussed: ideal conditions, ideal cases, and idealized theories. An ideal condition is a formula in which state variables occur, whose existential closure is false, and for which there is another formula that can be constructed out of the original formula such that the existential closure of the new (...) formula is true. An ideal case is a statement which is logically equivalent to a universal conditional which has an ideal condition as its antecedent. And an idealized theory is a set of false universal conditional statements. Alternative syntactic and semantic analyses are viewed and criticized. (shrink)

We use evidence from cognitive psychology and the history of science to examine the issue of the theory-ladenness of perceptual observation. This evidence shows that perception is theory-laden, but that it is only strongly theory-laden when the perceptual evidence is ambiguous or degraded, or when it requires a difficult perceptual judgment. We argue that debates about the theory-ladenness issue have focused too narrowly on the issue of perceptual experience, and that a full account of the scientific process requires an examination (...) of theory-ladenness in attention, perception, data interpretation, data production, memory, and scientific communication. We conclude that the evidence for theory-ladenness does not lead to a relativist account of scientific knowledge. (shrink)

In his Critique of Pure Reason, Kant makes the interesting, but obscure claim that the normative constraints that constitute the objectivity of our representations have their source ultimately in transcendental apperception. Keller focuses on this claim. He interprets Kant’s condition of transcendental apperception as the claim that I must represent myself in an impersonal way, and he argues that impersonal self-consciousness is a necessary condition under which I can distinguish my particular take on things from the way things are independently (...) of my own perspective on them. He elaborates his interpretation and defense of the condition of transcendental self-consciousness by discussing its role in each of the central arguments in the Critique in which the notion importantly figures: the transcendental deduction in both the first edition and in the second, the Analogies of Experience, the Paralogisms, and the second-edition refutation of idealism.

Modern professionals wield considerable power by virtue of their knowledge. However, they also feel beleaguered by the constraints they face and the public disapproval they often experience. These pressures combine to diminish the professional's sense of public responsibility and convert him or her in self-perception to a careerist.

The metamemory approach to memory confidence was extended and elaborated to deal with semantic memory tasks. The metamemory approach assumes that memory confidence is based on the products and processes of a completed memory task, as well as metamemory beliefs that individuals have about how their memory products and processes relate to memory accuracy. In two experiments participants were asked deceptive and nondeceptive questions involving geographical information. In both experiments, as predicted by the metamemory approach to memory confidence, there was (...) a positive confidence/ accuracy relationship for nondeceptive items and a negative relationship for deceptive items. Experiment 2 used items that constrained the memory strategies (e.g., hierarchical reasoning about spatial location) used by the participants. The results supported the hypothesis that the participants were aware of the levels of memory accuracy associated with the different strategies and used that information to generate their memory confidence judgments.

La enseñanza moral católica afirma que es necesario el consentimiento de los pacientes para autorizar las intervenciones sanitariasque les afectan, pero no especifica las condiciones para obtener dicho consentimiento o evaluar la capacidad de decisión. Aquí se presentan los artículos recogidos en este número que los autores han desarrollado a partir de las presentaciones que hicieron durante un coloquio reciente de la Asociación Internacional de Bioética Católica (IACB) celebrado en Quebec, Canadá. Contribuyen a promover el pensamiento ético sobre la capacidad (...) de toma dedecisiones y el consentimiento. De diversas formas, piden que se respete la dignidad de todos los pacientes y que se promueva su participación tanto como sea posible en la toma de decisiones sobre su salud. Consideran que la toma de decisiones es relacional y abarca una variedad de capacidades. Examinan el papel de los miembros de la familia y de otros partidarios de la toma de decisiones en la promoción de las capacidades de los pacientes, cuya condición de salud mental o discapacidad les impide a menudo cumplir con los estándares clínicos y legales típicos para la capacidad de toma de decisiones.

A discussion of Christian ethics focuses on the physician's image as a parent, warrior against death, expert, and teacher, and the oath that guides his or her practice.

A recent study(1) of sequence data from many different proteins has suggested that contemporary prokaryotes and eukaryotes may have shared a common ancestor as recently as 2 billion years ago (the molecular clock). Strong evidence from the geological record, however, indicates that oxygen‐producing microorganisms, perhaps similar to modern cyanobacteria, existed 3.5 billion years ago. The fossil evidence, therefore, suggests that any common ancestor of prokaryotes and eukaryotes must have existed at least 1.5 billion years earlier than suggested by the molecular (...) clock evidence. The discrepancy between molecular and geological evidence for the age of modern cells is considered here, as are aspects of gene descent in the tree of life that might help to account for it.

: Money motivates people, lubricates the movement of resources, mobilizes talent, and breaks down some barriers. But money also has a darker side; it can distract, corrupt, distort, and cruelly exclude. Money is a useful but unruly servant; sometimes, a hard master. The professional, at least in part, belongs to the world of money. We sometimes distinguish the amateur from the professional in that the amateur does it for love; the professional, for money. The professional has one foot in the (...) marketplace, but also, purportedly, professes something else--beyond the bottom line. The following discussion explores the morally complex ties and tensions between money and the medical professions. (shrink)

How Do I Save My Honor? is a powerful exploration of individual moral responsibility in a time of war. When individuals conclude that their leaders have violated fundamental ethical principles, what are they to do? Through the compelling personal stories of those in the U.S. and British government and military who struggled with these thorny issues during the war in Iraq, William F. Felice analyzes the degrees of moral responsibility that public officials, soldiers, and private citizens bear for the (...) actions of their governments. Examining the struggles of these contemporary men and women, as well as of historical figures facing similar dilemmas, the author weighs the profound difficulties of overcoming the intense pressures of misguided loyalty, patriotism, and groupthink that predominate during war.

This article articulates and defends F. H. Bradley's regress argument against external relations using contemporary analytic techniques and conceptuality. Bradley's argument is usually quickly dismissed as if it were beneath serious consideration. But I shall maintain that Bradley's argument, suitably reconstructed, is a powerful argument, plausibly premised, and free of such obvious fallacies as petitio principii. Thus it does not rest on the question‐begging assumption that all relations are internal, as Russell, and more recently van Inwagen, maintain. Bradley does not (...) attack external relations in order to affirm a doctrine of internal relations, and his monism is not derived from the internality of all relations, but from the self‐contradictory nature of all relations. For Bradley, it is the “relational situation”as such that is ontologically defective. (shrink)

A brief discussion is offered of what it means to say that a set of statements provides D-N explanation with special emphasis given to approximative D-N explanation. An idealized theory is seen to provide approximative D-N explanation. An ideal case provides explanation only if postulates are offered which connect the ideal antecedent condition with actual conditions. Such postulates will help in accounting for deviations between what the consequent of the ideal case entails and what actually occurs. Three ways are presented (...) for deciding on the acceptability of idealizations: (i) as actual conditions more closely approximate the ideal antecedent conditions specified in an ideal case, the more closely actual cases ought to approximate the consequent of the ideal case; (ii) the additional postulates connecting ideal antecedent conditions with actual conditions ought to account for deviations between what is entailed by an idealized theory and what actually occurs; and (iii) an idealized theory is explained by a more general theory when certain state variables in the more general theory are given extreme values. It is argued that (iii) is not a necessary condition for the acceptability of idealizations. (shrink)

In one of its versions, the principle of sufficient reason maintains that every true proposition has a sufficient reason for its truth. Recently, a number of philosophers have argued against the principle on the ground that there are propositions such as the conjunction of all truths that are ‘too big’ to have a sufficient reason. The task of this article is to show that such maximal propositions pose no threat to the principle. According to what is perhaps the most ‘popular’ (...) version of the principle to sufficient reason (PSR), every true proposition has a sufficient reason why it is true. Peter van Inwagen formulates the principle as follows: ‘for every truth, for everything that is so, there is a sufficient reason for its being true or being so.’ Like many contemporary philosophers, however, he rejects the principle. My purpose here is to show that the main philosophical argument against PSR rests on a mistaken assumption. There is also a ‘scientific’ argument against PSR that turns on considerations of quantum indeterminacy; but that argument lies beyond the scope of this discussion. (shrink)

Conventional wisdom has it that evolution makes a sham of morality, even if morality is an adaptation. I disagree. I argue that our best current adaptationist theory of meaning offers objective truth conditionsfor signaling systems of all sorts. The objectivity is, however, relative to species – specifically to the adaptive history of the signaling system in question. While evolution may not provide the kind of species independent objective standards that (e.g.) Kantians desire, this should be enough for the practical work (...) of justifying our confidence in the objectivity of moral standards. If you believe morality is an adaptation, you should be a moral realist. (shrink)

William F. May, a leading expert on medical ethics, here explores two of today's most crucial tests of the traditional covenant between physicians and patients--active euthanasia and health care reform.

This paper examines the form of mental representation of scientific theories in scientists and nonscientists. It concludes that images and schemas are not the appropriate form of mental representation for scientific theories but that mental models and perceptual symbols do seem appropriate for representing physical/mechanical phenomena. These forms of mental representation are postulated to have an analogical relation with the world and it is this relationship that gives them strong explanatory power. It is argued that the construct of naïve theories (...) as used in developmental psychology may be the appropriate form of mental representation for non physical/mechanical domains. The paper adopts a strong form of psychologism in the philosophy of science and argues that model-based approaches to scientific theories are more appropriate forms of representation for scientific theories than the formalist approaches that dominate current philosophy of science.

This paper presents an analysis of the forms of response that scientists make when confronted with anomalous data. We postulate that there are seven ways in which an individual who currently holds a theory can respond to anomalous data: (1) ignore the data; (2) reject the data; (3) exclude the data from the domain of the current theory; (4) hold the data in abeyance; (5) reinterpret the data; (6) make peripheral changes to the current theory; or (7) change the theory. (...) We analyze psychological experiments and cases from the history of science to support this proposal. Implications for the philosophy of science are discussed. (shrink)

Extracorporeal membrane oxygenation (ECMO) is a form of life support for cardiac and/or pulmonary failure with unique ethical challenges compared to other forms of life support. Ethical challenges with ECMO exist when conventional standards of care apply, and are exacerbated during periods of absolute ECMO scarcity when “crisis standards of care” are instituted. When conventional standards of care apply, we propose that it is ethically permissible to withhold placing patients on ECMO for reasons of technical futility or when patients have (...) terminal, short-term prognoses that are untreatable by ECMO. Under crisis standards of care, it is ethically permissible to broaden exclusionary criteria to also withhold ECMO from patients who have a low likelihood of recovery, to maximize the overall number of lives saved. Unilateral withdrawal of ECMO against a patient’s preferences is unethical under conventional standards of care, but is ethical under crisis standards of care to increase access to ECMO to others in society. ECMO should only be rationed when true scarcity exists, and allocation protocols should be transparent to the public. When rationing must occur under crisis standards of care, it is imperative that oversight bodies assess for inequities in the allocation of ECMO and make frequent changes to improve any inequities.
