A script concordance test was developed as an innovative tool for assessing ethical reasoning ability. An SCT of 12 medical ethical vignettes were constructed from the UNESCO Casebook on Human Dignity and Human Rights. The vignettes were reviewed by a panel of 15 medical experts before administration to a panel of 18 clinicians. The clinician’s answers were used to constitute the scoring key. The SCT was then administered to first and final year medical students. Data were analysed using SPSS. Internal (...) consistency was assessed using Cronbach’s alpha. SCT performance was tested for association with sex, year of study and race by comparing the mean SCT scores between categories within each variable. Internal consistency as measured by Cronbach’s alpha values, ranging from 0.597 to 0.902, indicated high intra-vignette reliability for 10 of the vignettes. Inter-vignette reliability was high at 0.797. Mean SCT scores were not significantly different between students of different gender, year of study and ethnicity. However, each vignette was able to distinguish between overall poor and good test performers. The SCT was able to differentiate between students with varying degrees of ethical reasoning ability.

Choices can be wise or foolish, and feelings can be apt or off the mark. So we judge, and it would be good to know what content these normative judgements carry. Gibbard offers an answer, and elaborates it. His theory explores what is at issue in narrowly moral questions, and in questions of rational thought and conduct in general.

Aristotle's biological works - constituting over 25% of his surviving corpus and for centuries largely unstudied by philosophically oriented scholars - have been the subject of an increasing amount of attention of late. This collection brings together some of the best work that has been done in this area, with the aim of exhibiting the contribution that close study of these treatises can make to the understanding of Aristotle's philosophy. The book is divided into four parts, each with an introduction (...) which places its essays in relation to each other and to the wider issues of the book as a whole. The first part is an overview of the relationship of Aristotle's biology to his philosophy; the other three each concentrate on a set of issues central to Aristotelian study - definition and demonstration; teleology and necessity in nature; and metaph themes such as the unity of matter and form and the nature of substance.

What precisely does aristotle mean when he asserts that something is (or comes to be) "for" "the" "sake" "of" something? I suggest that the answer to this question may be found by examining aristotle's position on the problem of reduction in biology, As it arises within his own scientific "and" "philosophical" context. I discuss the role of the concepts of "nature" and "potential" in aristotelian scientific explanation, And reformulate the reduction problem in that light. I answer the main question by (...) establishing that aristotle holds an "irreducibility" thesis in regard to the generation and development of a living organism, And that this thesis is the core of his conception of final causality. I conclude by arguing that aristotle's teleology is fundamentally "empirical" in character, And not an a priori doctrine brought "to" the study of nature. (shrink)

Theory-ladenness is the view that observation cannot function in an unbiased way in the testing of theories because observational judgments are affected by the theoretical beliefs of the observer. Its more radical cousin, incommensurability, argues that because there is no theory-neutral language, paradigms, or worldviews, cannot be compared because in different paradigms the meaning of observational terms is different, even when the word used is the same. There are both philosophical and practical components to these problems. I argue, using a (...) procedurally-defined, theory-neutral experiment that paradigms are indeed commensurable. The practical problems of theory ladenness include experimental design, failure to interpret observations correctly, possible experimenter bias, and difficulties in data acquisition. I suggest that there are methods to deal with these problems, although sometimes they cannot be dealt with completely. I believe that the philosophical problems of theory-ladenness have been solved, although the practical problems remain. (shrink)

Calibration, the use of a surrogate signal to standardize an instrument, is an important strategy for the establishment of the validity of an experimental result. In this paper, I present several examples, typical of physics experiments, that illustrate the adequacy of the surrogate. In addition, I discuss several episodes in which the question of calibration is both difficult to answer and of paramount importance. These episodes include early attempts to detect gravity waves, the question of the existence of a 17–keV (...) neutrino, and the question of the existence of a Fifth Force in gravity. I argue that in these more complex cases, the adequacy of calibration, in an extended sense, was both considered and established. (shrink)

In this chapter, Ayn Rand's new concept of morality is contrasted with familiar concepts according to which morality is an imposition on an individual that demands that he forgo his own interests as a sacrifice, whether to other people or to God. This chapter explores Rand's view that man's life is the standard of value and looks at each value that John Galt describes as supreme and ruling and, then, at the range of other values that Rand thinks man's life. (...) In discussing the supreme and ruling values, the chapter considers the three virtues that correspond to them: rationality, productiveness, and pride. It also looks at the four remaining virtues Rand identifies such as independence, integrity, honesty, and justice. Rand's conception of justice and the facts it recognizes is powerfully illustrated in Atlas Shrugged. Finally, the chapter examines Rand's view of heroism, which is closely connected with her ethics.

The missing piece of the puzzle: the discovery of the Higgs boson On July 4, 2012 the CMS and ATLAS collaborations at the large hadron collider jointly announced the discovery of a new elementary particle, which resembled the Higgs boson, the last remaining undiscovered piece of the standard model of elementary particles. Both groups claimed to have observed a five-standard-deviation effect above background, the gold standard for discovery in high-energy physics. In this essay I will briefly discuss the how the (...) CMS collaboration performed the experiment and analyzed the data. I will also show the experimental results. (shrink)

The philosopher and novelist Ayn Rand is a cultural phenomenon. Her books have sold more than twenty-eight million copies, and countless individuals speak of her writings as having significantly influenced their lives. Despite her popularity, Rand’s philosophy of Objectivism has received little serious attention from academic philosophers. _Concepts and Their Role in Knowledge_ offers scholarly analysis of key elements of Ayn Rand’s radically new approach to epistemology. The four essays, by contributors intimately familiar with this area of her work, discuss (...) Rand’s theory of concepts—including its new account of abstraction and essence—and its central role in her epistemology; how that view leads to a distinctive conception of the justification of knowledge; her realist account of perceptual awareness and its role in the acquisition of knowledge; and finally, the implications of that theory for understanding the growth of scientific knowledge. The volume concludes with critical commentary on the essays by distinguished philosophers with differing philosophical viewpoints and the author’s responses to those commentaries. This is the second book published in Ayn Rand Society Philosophical Studies, which was developed in conjunction with the Ayn Rand Society to offer a fuller scholarly understanding of this highly original and influential thinker. The Ayn Rand Society, an affiliated group of the American Philosophical Association, Eastern Division, seeks to foster scholarly study by philosophers of the philosophical thought and writings of Ayn Rand.

Introduces the philosophical thoughts of Ayn Rand with overviews of her life and intellectual development, then covers her objectivist epistemology, giving attention to both her theory of perception and to her original theory of concepts. Other subjects covered include objectivist ethics, Rand's moral theory and politics, and her aesthetics.

Charles Darwin's famous 1882 letter, in response to a gift by his friend, William Ogle of Ogle's recent translation of Aristotle's "Parts of Animals," in which Darwin remarks that his "two gods," Linnaeus and Cuvier, were "mere school-boys to old Aristotle," has been though to be only an extravagantly worded gesture of politeness. However, a close examination of this and other Darwin letters, and of references to Aristotle in Darwin's earlier work, shows that the famous letter was written several weeks (...) after a first, polite letter of thanks, and was carefully formulated and literally meant. Indeed, it reflected an authentic, and substantial, increase in Darwin's already high respect for Aristotle, as a result of a careful reading both of Ogle's Introduction and of more or less the portion of Ogle's translation which Darwin says he has read. Aristotle's promotion to the pantheon, as an examination of the basis for Darwin's admiration of Linnaeus and Cuvier suggests, was most likely the result specifically of Darwin's late discovery that the man he already knew as "one of the greatest... observers that ever lived" was also the ancient equivalent both of the great modern systematist and of the great modern advocate of comparative functional explanation. It may also have reflected some real insight on Darwin's part into the teleological aspect of Aristotle's thought, indeed more insight than Ogle himself had achieved, as a portion of their correspondence reveals.

In this article I suggest a tripartite classification of scientific activity; discovery, pursuit, and justification. I believe that such a classification can give us a more adequate description of scientific practice, help illuminate the various roles that evidence plays in science, and may also help to partially resolve differences between “constructivist” and “epistemologist” views of science. I argue that although factors suggested by the constructivists such as career goals, professional interests, utility for future practice, and agreement with existing commitments do (...) enter into pursuit, it is experimental evidence that is decisive in justification. I illustrate this with two case studies from the history of contemporary science, experiments on atomic parity violation and their relation to the Weinberg-Salam unified theory of electroweak interactions and the fifth force in gravity. I also answer some of the criticisms offered of my earlier account of the episode of atomic parity violation. (shrink)

At 47e–53c of the Timaeus Plato presents his most detailed metaphysical analysis of particulars. We are told about the construction of the physical universe, the ways we can and cannot talk about the phenomena produced, and about the two causes – Necessity and Intelligence – which govern the processes and results of production. It seems to me that we are told too much and too little: too much, because we have two accounts of the generation of phenomenal particulars – one, (...) the ‘formal account’, which makes use of the receptacle, Forms and form-copies, and a second, the ‘geometrical account’, which appeals to geometrical shapes, the Demiurge and, apparently, matter; too little, because there is insufficient guidance as to how to relate the two accounts.

The precarious rights of senior citizens, especially those who are highly educated and who are expected to counsel and guide the younger generations, has stimulated the creation internationally of advocacy associations and opinion leader groups. The strength of these groups, however, varies from country to country. In some countries, they are supported and are the focus of intense interest; in others, they are practically ignored. For this is reason we believe that the creation of a network of all these associations (...) is essential. The proposed network would act as a support for the already-existing policies of the United Nations’ High Commission for Human Rights, of independent experts, and of the Global Alliance for the Rights of Older People. All three have long ago recommended the creation of a recognized instrument for uniting presently scattered efforts. The proposed network, therefore, will seek to promote the international exchange of relevant expertise, and it will reinforce the commitments and actions that single countries are currently taking to meet these objectives. For example, informative public events can be organised to promote particular support initiatives and to provide an opportunity for new members of the network to be presented. The network will promote health for senior citizens, disease prevention, senior mobility, safe free time for seniors, alimentary education, protection against new risks and dangers, as well as equity in the services necessary for seniors to adopt new information and communication technologies. In the case of retired academic members, the network will promote equality with respect to continuing use of digital technologies (particularly email), continuing access to research libraries, and the guaranteed ability for seniors to fund their own research programs and to deliver free seminars.

On the basis of an analysis of a single paper on plate tectonics, a paper whose actual content is nowhere in evidence, Frederick Suppe concludes that no standard model of confirmation—hypothetico-deductive, Bayesian-inductive, or inference to the best explanation—can account for the structure of a scientific paper that reports an experimental result. He further argues on the basis of a survey of scientific papers, a survey whose data and results are also absent, that papers which have a rather stringent length limit, (...) such as the one on plate tectonics, are typical of science. Thus, he concludes that no standard confirmation scheme is capable of dealing with scientific practice. Suppe also requires that an adequate model of philosophical testing should be able to account for everything in such scientific papers, in which space is at a premium. (shrink)

Experiments often disagree. How then can scientific knowledge be based on experimental evidence? In this paper I will examine four episodes from the history of recent physics: the suggestion of a Fifth Force, a modification of Newton’s law of gravitation; early attempts to detect gravitational radiation ; the claim that a 17-keV neutrino exists; and experiments on atomic-parity violation and on the scattering of polarized electrons and their relation to the Weinberg-Salam unified theory of electroweak interactions. In each of these (...) episodes discordant results were reported, and a consensus was later reached that one result—or set of results—was incorrect. I will examine the process of reaching that consensus. I will show that the decision was reached by reasoned discussion based on epistemological and methodological criteria. It then follows that we may use experimental evidence as the basis of scientific knowledge. (shrink)

This chapter discusses a pair of interrelated theses that are hallmarks of Objectivism: the benevolent universe premise and the heroic view of man. These theses are dramatic consequences of the defining essentials of the philosophy, and they are central to the sense of life conveyed by Ayn Rand's novels. The benevolent universe premise permeates all her novels, and much of her non‐fiction, but it seems that she first conceptualized this view under this name sometime in the 1940s. The benevolent universe (...) premise is what Rand calls a metaphysical value‐judgment. It is metaphysical in that it answers a question about the nature of the universe. The chapter briefly describes the heroic view of man, looking not at the content of Rand's view of heroism, but at how this view of heroism colored her view of humanity and of specific human beings.

Taking Parenting Public makes a compelling case that parenting has become dangerously undervalued in America today. It calls for a new investment—both personal and public—into the work of raising children and argues that we are all "stockholders" in the next generation. With a foreword by Sylvia Ann Hewlett and Cornel West, Taking Parenting Public crosses boundaries to bring together thinkers from diverse fields spanning the political spectrum. It features contributions from distinguished experts in economics, political science, public policy, child development, (...) public health, history, and the media. While recent books have focused on working mothers or absent fathers, Taking Parenting Public is the first volume to take a comprehensive look at the common struggles of parents. These essays go beyond the usual chest-beating about busy parents torn between work and family demands to suggest bold solutions. Instead of the typical call for "parent replacement"—more child care, more after school programs and more mentors—the contributors offer fresh strategies for "parent replenishment," ways to put mothers and fathers back into the lives of their children not only as economic providers, but also as emotional and moral providers.

A number of scholars have suggested that Milgram’s laboratory studies of obedience offer an incisive analysis of the behavior of the Holocaust perpetrators. The present paper rejects that position. The contrasts between the two events, at every level of analysis, are striking: In Milgram’s research, innocent peers were harmed in the context of science; in the Holocaust, rabidly hated, subhuman enemies were murdered in the context of ‘war’. With regard to underlying psychological mechanisms, the evidence questioning the relevance of Milgram’s (...) research is equally compelling: obedience pressures had little role in the Holocaust. Most of the Nazi perpetrators showed no remorse or moral distress over the murders and perhaps most critically, virtually all of the killers knew that they could choose not to participate in the killings.

Cooper has claimed to have found evidence for faster-than-light particles by reanalyzing the data of Chamberlain et al. in their paper reporting the discovery of the antiproton. A careful reanalysis of this same data gives no evidence to support Cooper's claim.
