In lieu of an abstract, here is a brief excerpt of the content:KARL ASCHENBRENNER, 19x 1-1988 Karl Aschenbrenner was born in Bison, Kansas, on November 20, 1911. He received the A. B. degree from Reed College in 1934 and his graduate degrees at Berkeley (M. A., 1938; Ph.D., 194o). After two years as an instructor at Reed College, he served in the U.S. Naval Reserve (Lieutenant in Meteorology ) from 1943 to 1946. From 1946 to 1948, he taught in the (...) Department of Speech at Berkeley and thereafter in the Department of Philosophy until his retirement in 1978. His teaching was devoted mainly to aesthetics and to the history of philosophy, most notably his course on Kant. For many years he was active as a trustee of the American Society for Aesthetics, and from 1961 as a member of the Journal's founding executive committee and, after incorporation, of the Board of Directors. Karl's first two years of attachment to theJournal coincided with service as chairman of the Department of Philosophy. This conjunction enabled him to be extraordinarily helpful in dealing with problems of bringing the Journal to birth--problems of funding, editorial appointments, publication policies, and business arrangements with the University of California Press. He welcomed the opportunity offered the Philosophy Department of collaborating in the publishing venture recommended by a special committee of the American Philosophical Association in 1958. The recognition early won by the Journal for its articles and reviews answered to his hope and work for success. At the annual meeting of the Board of Directors in San Francisco in 1987, the twenty-fifth birthday of the Journal was celebrated as was his twenty-seven years of diligent care for theJournafs excellence. Karl was a regular contributor to the philosophy series published by the University of California prior to three books issued by D. Reidel: The Concepts ofValue(1971), The ConceptsofCriticism(1974) and AnalysisofAppraisiveCharacterization (1983). He received Guggenheim, Fulbright, and NEH fellowships. Despite a physically disabling stroke in 1979, he continued his trips to Budapest which he began in 1972. He was concerned to study a non-IndoEuropean language spoken by people of European culture and had selected the Magyar tongue spoken in Hungary. He learned the language to test theories he advanced about appraisive concepts. He discovered in the structure of Magyar a mode of valuing embodied in verb usage differing significantly [333] 334 from the special appraisive vocabularies of English and German. Besides his lectures in Hungary, he responded to invitations to lecture received from universities in England, Austria, Poland, Bulgaria, and Romania. Shortly after his return to Budapest on his eleventh trip, he died of a massive stroke on July 4, 1988. He is buried there in a city he loved, especially for its music. He is survived by Marie, his wife of fifty-one years, and three children: Lisabeth, an attorney in Los Angeles; Peter, a judge in Fairbanks; and John, a composer in New York. E. W. STRONG...

This timely book examines the interaction of health research and regulation with law through empirical analysis and the application of key anthropological concepts to reveal the inner workings of human health research. Through ground-breaking empirical inquiry, Regulatory Stewardship of Health Research explores how research ethics committees (RECs) work in practice to both protect research participants and promote ethical research.This thought-provoking book provides new perspectives on the regulation of health research by demonstrating how RECs and other regulatory actors seek to fulfil (...) these two functions by performing a role of 'regulatory stewardship'. This involves guiding researchers through stages of research approval, as well as seeking to maximise benefits for participants and society while minimising risks. Arguing that participant protection and research promotion should rightly be treated as twin objectives for health research regulators, this book asserts that there is a need for more overt recognition of the importance and function of the deliberative space in which RECs can negotiate the risks relevant to a research application.This book is a key resource for academics and students interested in health research and regulation, and the dynamic interaction of ethics and the law. Regulators and policy-makers will also find it to be an insightful and illuminating text for the practical insights that it reveals about research governance in action. (shrink)

While ethical norms for conducting academic research in the United Kingdom are relatively clear, there is little empirical understanding of how university research ethics committees (RECs) themselves operate and whether they are seen to operate well. In this article, we offer insights from a project focused on the Scottish university context. We deployed a three-sided qualitative approach: (i) document analysis; (ii) interviews with REC members, administrators, and managers; and (iii) direct observation of REC meetings. We found that RECs have diverse (...) operation and vary in terms of what members understand to be the remit of their REC and what should constitute the content of ethics review. Overall, though, most participants perceive university RECs as operating well. When asked what they consider to be areas for further improvement, most commented on: implementation of an online system; more experience with how to evaluate various kinds of research projects; best practice exchange and training opportunities; more accurate reflection of the REC role as part of the university’s workload allocation model; and greater recognition of the importance of research ethics governance in the university’s research environment, and, for the members themselves, their career advancement. Based on our findings and subsequent discussions during an end-of-project roundtable with stakeholders, we propose a model of collaboration that can address some of the identified areas that could benefit from further improvement. This model would facilitate a heightened awareness of the importance of supporting REC members in their own effort in assisting students and staff alike in undertaking as ethically robust research as possible.

Without Good Reason offers a clear critical account of the debate in philosophy and cognitive science about whether humans are rational. Various experiments performed over the last several decades have been interpreted as showing that humans are irrational; certain philosophers, on the other hand, have argued that it is a conceptual truth that humans must be rational. Edward Stein concludes that the question of human rationality should be answered not conceptually but empirically: the resources of a fully developed cognitive (...) science need to be used not only to answer this question but generally in investigations of the nature of human knowledge and understanding.

This is a major contribution to the theory of rational choice which will be of particular interest to philosophers and economists. The author sets out the foundations of rational choice, and then sketches a dynamic choice framework in which principles of ordering and independence follow from a number of apparently plausible conditions. However, there is potential conflict among these conditions, and when they are weakened to avoid it the usual foundations of rational choice no longer prevail. The thrust of the (...) argument is to suggest that the theory of rational choice is less deterministic than many suppose. (shrink)

Salient landmarks enhance route learning. We hypothesised that semantically salient nostalgic landmarks would improve route learning compared to non-nostalgic landmarks. In two experiments, participants learned a route through a computer-generated maze using directional arrows and wall-mounted pictures. On the test trial, the arrows were removed, and participants completed the maze using only the pictures. In the nostalgia condition, pictures were of popular music artists and TV characters from 5 to 10 years ago. In the control condition, they were recent pictures (...) of these same artists and characters. In Experiment 1, in the test trial, participants in the nostalgia condition completed the maze faster than controls. Experiment 2 conceptually replicated these findings and extended them by exploring boundary conditions. Participants had to learn two mazes sequentially. In Maze 1, we placed nostalgic/control landmarks only at non-decision points (whereas we placed them at decision points in Experiment 1). In Maze 2, we placed nostalgic/control landmarks at decision points during acquisition but removed them in the test trial (whereas they were present in the test trial in Experiment 1). In both mazes, participants in the nostalgia (compared to control) condition completed the test trial faster. (shrink)

This book aims to provide scientists and engineers, and those interested in scientific issues, with a concise account of how the nature of scientific knowledge evolved from antiquity to a seemingly final form in the Twentieth Century that now strongly limits the knowledge that people would like to gain in the Twenty-first Century. Some might think that such issues are only of interest to specialists in epistemology (the theory of knowledge); however, today's major scientific and engineering problems--in biology, medicine, environmental (...) science, etc.--involve enormous complexity, and it is precisely this complexity that runs up against the limits of what is scientifically knowable. To understand the issue, one must appreciate the radical break with antiquity that occurred with the birth of modern science in the Seventeenth Century, the problems of knowledge and truth engendered by modern science, and the evolution of scientific thinking through the Twentieth Century. While originally aimed at practicing scientists and engineers, it is my hope that this book can provide a generally educated person with a basic understanding of how our perspective on scientific knowledge has evolved over the centuries to escape pre-Galilean commonsense thinking. Such an appreciation is not only beneficial for one's general education, but is important for non-scientists who must teach young students or make policy decisions in government or business.

Imprecise probabilities are often modelled with representors, or sets of probability functions. In the recent literature, two ways of interpreting representors have emerged as especially prominent: vagueness interpretations, according to which each probability function in the set represents how the agent's beliefs would be if any vagueness were precisified away; and comparativist interpretations, according to which the set represents those comparative confidence relations that are common to all probability functions therein. I argue that these interpretations have some important limitations. I (...) also propose an alternative—the functional interpretation—according to which representors are best interpreted by reference to the roles they play in the theories that make use of them.

Moral naturalists are often said to have trouble making sense of inter-communal moral disagreements. The culprit is typically thought to be the naturalist’s metasemantics and its implications for sameness of meaning across communities. The most familiar incarnation of this metasemantic challenge is the Moral Twin Earth argument. We address the challenge from the perspective of analytic naturalism, and argue that making sense of inter-communal moral disagreement creates no special issues for this view.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 65.1 (2004) 155-157 [Access article in PDF] In Memoriam John F. Callahan John Francis Callahan, Professor Emeritus of Philosophy and Classics at Georgetown University, died 14 July 2003 after open-heart surgery performed 6 June and was buried with full military honors 17 September at Arlington National Cemetery. His funeral Mass at the Old Post Chapel was concelebrated by his old friend and former (...) colleague, Father Edward W. Bodnar, S.J., who had also concelebrated a memorial Mass in the Jesuit Chapel at Georgetown 5 August.John served on the Board of Editors and the Board of Directors of the Journal of the History of Ideas from 1970 until his death and was Vice-President from 1985. Throughout thirty-three years, during which he never missed a meeting until the last, he devoted unstinted time and energy to the affairs of the Journal, rigorously scrutinizing every problem, from matters of editorial policy through changes in leadership, location, and membership on the Editorial Board to proposals for expenditures and questions of format and style. He was a meticulous reader of manuscripts and applied the most stringent standards to his consideration of both content and modes of expression. No mistake in Greek typography escaped his vigilance. He brought to the annual meetings a distinctive elegance and an unusual sense of collegiality that derived both from his devotion to the Journal itself and from his long friendship with some of the older members of the Board, such as Paul Kristeller and Richard McKeon.John was a life member of the American Philological Association (since 1940) and served with distinction from 1976 to 1986 as its delegate to the International Federation of Classical Studies (FIEC), attending its meetings in Budapest and Helsinki. A scholar of exceptionally wide-ranging interests, he was best known for his studies of the concept of time in ancient philosophy and his critical edition of Gregory of Nyssa, De oratione dominica et De beatitudinibus, which he completed at Dumbarton Oaks after he retired from Georgetown.Born in Chicago 13 May 1912, he began the study of Greek and Latin at St. Ignatius Prep, where he was also introduced to opera, a lifelong passion, by one of his Jesuit teachers. He received the A.B. in 1933 and the A.M. in 1934 from Loyola University, Chicago, which on Founder's Day, 1965, honored him with an award for distinguished contributions to classical scholarship. He received the Ph.D. in 1940 from the University of Chicago, where he studied with Richard McKeon and Werner Jaeger, the two principal, very different influences on his approach to philosophy and philology. Henry Prescott and Carl Darling Buck were two other members of that fabulous generation of classical scholars at Chicago who made a lasting impression on him. His interest in Plautus, Greek and Roman linguistics, and comparative grammar continued throughout his life, contributing to what a former colleague at Dumbarton Oaks has described as an uncanny ability to penetrate beneath the surface of the classical languages, to "peer into their deep structure."John was a Teaching Fellow at the University of Chicago, 1936-37, Instructor at Loyola University, 1937-40, Visiting Instructor, Harvard University, 1940-41, Assistant Professor, Loyola University, 1941-43, Associate Professor and Professor of Classics and Philosophy, Georgetown University, from 1946 until he retired in 1978, and Project Director at Dumbarton Oaks, Harvard University, 1977-86. He served in the United States Navy from 1943 to 1946, working in Naval Communications. He rarely [End Page 155] spoke of his part in breaking the Japanese code, but often referred to such comrades in arms as Sam Atkins and Richmond Lattimore, who like him returned to teaching as soon as World War II was over.John's teaching was enriched by his research, which was supported by a notable succession of fellowships, from the Rockefeller Foundation in 1947, the Ford Foundation for the Advancement of Education, 1953-54, the Fulbright Commission, 1953-55, the Guggenheim Foundation, 1958-59, and the National Endowment for the Humanities, 1967.

Each year, over 200 million people are infected with the malaria parasite, nearly half a million of whom succumb to the disease. Emerging genetic technologies could, in theory, eliminate the burden of malaria throughout the world by intentionally eradicating the mosquitoes that transmit the disease. In this paper, we offer an ethical examination of the intentional eradication of Anopheles gambiae, the main malaria vector of sub-Saharan Africa. In our evaluation, we focus on two main considerations: the benefit of alleviating the (...) malaria burden, and the loss of value that would accompany the eradication of the species. We outline a typology of the different ways in which species are valued or could be valuable, then use that typology to appraise the value of the species in question. We argue that Anopheles gambiae has minor (and redundant) instrumental value, little final subjective value and no objective final value. (shrink)

I present an intractable puzzle for the currently popular view that belief is weak—the view that expressions like ‘S believes p’ ascribe to S a doxastic attitude towards p that is rationally compatible with low credence that p. The puzzle concerns issues that arise on considering beliefs in conditionals. I show that proponents of weak belief either cannot consistently apply their preferred methodology when accommodating beliefs in conditionals, or they must deny that beliefs in conditionals can be used in reasoning.

I propose a solution to the paradox of the kalela dance, as presented by Richard Werbner, based on a variety of liberalism I once identified.

Could anything provide a philosophically convincing mark of the mental in simple organisms (Lloyd 1984)? Individual organisms’ capacities to modify behavior adaptively as a result of past encounters with the environment might mark the first step in the phylogeny of minds. The simplest examples of mental representation are likely to be found in the simplest forms of animal learning.The most scientifically rigorous test case of “bottom- up” strategies in cognitive neuroscience is provided by current studies of the cellular and molecular (...) biology of associative learning in higher invertebrates, but particularly gastropod molluscs, snails or slugs (Quinn 1984). For the relevant neurobiological research community (Farley and Alkon 1985; Hawkins, Clark, and Kandel 1986), “Bottom-up” does not just mean letting one’s study of the properties of the nervous system control one’s analyses of animal behavior or cognition.

What is the relationship between myths and the iconic? This paper analyzes a dialogue from an R.K. Narayan novel which suggests a criterion for belonging to a natural kind in the world of myth, a criterion which makes reference to the iconic.

This paper argues for the value of philosophers in a school of social sciences within a university, for fixing what I call disciplinary constitutions. A disciplinary constitution is a statement of “How our discipline works: how we achieve the ends of our discipline.” A lot of people depend on a constitution, but such a thing usually runs into problems and philosophers can identify these problems and propose solutions. I suggest that it is essential for the autonomy of an ambitious school (...) to be able to do such work internally. (shrink)

The relation between ex falso and disjunctive syllogism, or even the justification of ex falso based on disjunctive syllogism, is an old topic in the history of logic. This old topic reappears in contemporary logic since the introduction of minimal logic by Johansson. The disjunctive syllogism seems to be part of our general non-problematic inferential practices and superficially it does not seem to be related to or to depend on our acceptance of the frequently disputable ex falso rule. We know (...) that the acceptance of the ex falso is a sufficient condition for the acceptance of the disjunctive syllogism, but the interesting question is: is the ex falso a necessary condition for the acceptance of the disjunctive syllogism? The aim of the present paper is to discuss some possible ways to define systems that combines the preservation of the disjunctive syllogism with the rejection of the ex falso. (shrink)

The Dialectical Forge identifies dialectical disputation as a primary formative dynamic in the evolution of pre-modern Islamic legal systems, promoting dialectic from relative obscurity to a more appropriate position at the forefront of Islamic legal studies. The author introduces and develops a dialectics-based analytical method for the study of pre-modern Islamic legal argumentation, examines parallels and divergences between Aristotelian dialectic and early juridical jadal-theory, and proposes a multi-component paradigm—the Dialectical Forge Model—to account for the power of jadal in shaping Islamic (...) law and legal theory.In addition to overviews of current evolutionary narratives for Islamic legal theory and dialectic, and expositions on key texts, this work shines an analytical light upon the considerably sophisticated “proto-system” of juridical dialectical teaching and practice evident in Islam’s second century, several generations before the first “full-system” treatises of legal and dialectical theory were composed. This proto-system is revealed from analyses of dialectical sequences in the 2nd/8th century Kitāb Ikhtilāf al-ʿIrāqiyyīn / ʿIrāqiyyayn through a lens molded from 5th/11th century jadal-theory treatises. Specific features thus uncovered inform the elaboration of a Dialectical Forge Model, whose more general components and functions are explored in closing chapters. (shrink)

This paper responds to the question of whether the Internet has made lectures obsolete and Matthew Pickles’ investigation of why lectures persist. It is written as a pastiche of R.K. Narayan, about whom a somewhat parallel question is probably asked. Pickles refers to a logic lecturer so dry people went swimming, and a pastiche approach is an alternative.

I am not sure who said that liberalism merely alternates between ethics and economics – was it Karl Kraus? – but at first glance the claim is plausible. In this paper I argue that there are varieties of liberalism which do not. Some depend on a nature-culture distinction and some appeal to simplicity in a way that seems aesthetic. In the appendix I introduce a problem for utilitarianism.

Are there circumstances under which scientists and engineers doing their ordinary jobs can be thought of as participants in a social movement? The technoscientists analyzed in this article are at the forefront of a new way of doing chemistry; they are attempting to redesign chemical products and synthesis pathways to significantly reduce health effects and environmental damage from industrial chemicals. Green chemistry practitioners and entrepreneurs now constitute a small minority of chemists and chemical engineers in the university, government, and corporate (...) sectors, but the innovators gradually are institutionalizing their efforts and winning converts. Drawing on concepts from social movement theory, the authors argue that examining green chemistry as a social movement sheds light on the intentional social organization of emerging scientific and engineering disciplines, advances thinking about the role of expertise in social change, and uncovers a possible pathway toward reconstructing chemical technologies on a more environmentally sustainable basis. The article closes with questions about potential coalitions among green chemists and engineers, regulators, and activist sectors of civil society. (shrink)

Approaches to Meaning in Music presents a survey of the problems and issues inherent in pursuing meaning and signification in music, and attempts to rectify the conundrums that have plagued philosophers, artists, and theorists since the time of Pythagoras. This collection brings together essays that reflect a variety of diverse perspectives on approaches to musical meaning. Established music theorists and musicologists cover topics including musical aspect and temporality, collage, borrowing and association, musical symbols and creative mythopoesis, the articulation of silence, (...) the mutual interaction of cultural and music-artistic phenomena, and the analysis of gesture. Contributors are Byron Almén, J. Peter Burkholder, Nicholas Cook, Robert S. Hatten, Patrick McCreless, Jann Pasler, and Edward Pearsall. (shrink)

Defined as the “deliberate, large-scale manipulation of the planetary environment in order to counteract anthropogenic climate change,” geoengineering is an umbrella term that captures a variety of different technologies. This chapter will offer a concise overview of geoengineering as a response to anthropogenic climate change, with a primary focus on the ethical aspects this grouping of technologies engenders. We will start by exploring why it is that we are even considering these technologies rather than just doubling down on mitigation and (...) adaptation, and then move into a brief explanation of some of the different technologies under consideration. With that brief explanation out of the way, we will then introduce a number of ethical considerations that some or all of the technologies give rise to. For the sake of organization, we will look at different ethical considerations that arise: (1) during research into these technologies; (2) after deployment or full-scale use of these technologies; and (3) in the kind of world in which these technologies have become the new normal.

As the sustained and devastating extent of the coronavirus disease 2019 pandemic becomes apparent, a key focus of public scrutiny in the UK has centred on the novel legal and regulatory measures introduced in response to the virus. When those measures were first implemented in March 2020 by the UK Government, it was thought that human rights obligations would limit excesses of governmental action and that the public had more to fear from unwarranted intrusion into civil liberties. However, within the (...) first year of the pandemic’s devastation in the UK, a different picture has emerged: rather than through action, it is governmentalinactionthat has given rise to greater human rights concerns. The UK Government has been roundly criticized for its inadequate response, including missteps in decision-making, delayed implementation and poor enforcement of lockdown measures, abandonment of testing, shortages of critical resources and inadequate test and trace methods. In this article, we analyse the UK Government’s missteps and compare them with published international guidance; we also contrast the UK’s decisions with those taken by several other countries to understand how its actions and inactions have contributed to unfavourable outcomes. Using an analytical perspective that demonstrates how human rights are both a protection from the power of the state and a requirement that governmental powers are used to protect the lives, health and wellbeing of citizens, we argue that the UK Government’s failure to exercise their powers competently allowed the virus to spread without ensuring the country had the means to manage a high case load. This abject failure has led to one of the highest rates of deaths per capita worldwide. We offer several lessons that can be learnt from this unfortunate, but preventable, situation. (shrink)

This paper examines the ethics of the Australian business community’s responses to the phenomenon of modern slavery. Engaging a critical discourse approach, we draw upon a data set of submissions by businesses and business representatives to the Australian government’s Joint Standing Committee on Foreign Affairs, Defence and Trade ‘Parliamentary Inquiry into Establishing a Modern Slavery Act in Australia’—which preceded the signing into law of Australia’s Modern Slavery Act 2018—to examine the business community’s discursive construction in their submissions of the ethical–political (...) concept of freedom. The paper shows how the concept of freedom was employed by Australian business in a manner that privileged their own subject status and advocated for legislation with minimal burden. Relating this contemporary case to a longer historical context, we show how Australian business responses towards modern slavery map onto liberal and neoliberal ethics in which the freedom of the propertied takes precedent over that of the property-less. Further, we show discursive similarities in the arguments presented by modern Australian businesses and certain historical efforts by members of the business community to privilege commercial freedoms in responses to 18th and 19th Century abolitionist movements. Overall, our research makes two important contributions: first, it highlights the value of a critical discourse lens in business ethics research to show how business and other stakeholders in the field construct and shape their own and other’s ethically-laden understanding of reality; and second, it presents a case for considerable scepticism about the motivation of business to employ the freedoms made available to it under neo/liberal discourse to confront a key human rights challenge.

Fertilization triggers cytoplasmic movements in the frog egg that lead in mysterious ways to the stabilization of β‐catenin on the dorsal side of the embryo. The novel Huluwa (Hwa) transmembrane protein, identified in China, is translated specifically in the dorsal side, acting as an egg cytoplasmic determinant essential for β‐catenin stabilization. The Wnt signaling pathway requires macropinocytosis and the sequestration inside multivesicular bodies (MVBs, the precursors of endolysosomes) of Axin1 and Glycogen Synthase Kinase 3 (GSK3) that normally destroy β‐catenin. In (...) Xenopus, the Wnt‐like activity of GSK3 inhibitors and of Hwa mRNA can be blocked by brief treatment with inhibitors of membrane trafficking or lysosomes at the 32‐cell stage. In dorsal blastomeres, lysosomal cathepsin is activated and intriguing MVBs surrounded by electron dense vesicles are formed at the 64‐cell stage. We conclude that membrane trafficking and lysosomal activity are critically important for the earliest asymmetries in vertebrate embryonic development. (shrink)

What is R.K. Narayan’s position in relation to his story “Such perfection”? It is natural to interpret him as conveying a message similar to one Western readers are familiar with from ancient Greek myths: fear perfection; it offends the gods. But there is room for a more complicated interpretation.

In our previous work we proved the conjecture NP = PSPACE by advanced proof theoretic methods that combined Hudelmaier’s cut-free sequent calculus for minimal logic with the horizontal compressing in the corresponding minimal Prawitz-style natural deduction. In this Addendum we show how to prove a weaker result NP = coNP without referring to HSC. The underlying idea is to omit full minimal logic and compress only “naive” normal tree-like ND refutations of the existence of Hamiltonian cycles in given non-Hamiltonian graphs, (...) since the Hamiltonian graph problem in NPcomplete. Thus, loosely speaking, the proof of NP = coNP can be obtained by HSC-elimination from our proof of NP = PSPACE. (shrink)

We associate the method of reflective equilibrium with developing principles of social justice, but it can also be used on a literary canon, with the aim of identifying principles of inclusion and exclusion. But I note three risks of doing so, using the American literary canon as an example.
