In the standard formulation of game theory, agents use mixed strategies in the form of objective and probabilistically precise devices to conceal their actions. We introduce the larger set of probabilistically imprecise devices and study the consequences for the basic results on normal form games. While Nash equilibria remain equilibria in the extended game, there arise new Ellsberg equilibria with distinct outcomes, as we illustrate by negotiation games with three players. We characterize Ellsberg equilibria in two-person conflict and coordination games. (...) These equilibria turn out to be related to experimental deviations from Nash equilibrium play. (shrink)

Frank E. Zachos offers a comprehensive review of one of today's most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts (...) found in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name ("species") is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.

One of our great contemporary scientists presents ten insights that illuminate what every thinking person needs to know about what the world is and how it works. Nobel Prize winner Frank Wilczek's Fundamentals is built around a simple but profound idea: the models of the world we construct as children are practical and adequate for everyday life, but they do not bring in the surprising and mind-expanding revelations of modern science. To do that, we must look at the world (...) anew, combining clear thinking with an openness to wonder. This "born again" world is in many ways larger, fuller, and much stranger than it appears. Through an exploration of space, time, matter, and ideas--and equipped with facts, questions, and brilliant speculations--Wilczek guides us through the past, present, and future of fundamental science. Readers will emerge with an expanded vision of our universe. Author Bio: Frank Wilczek won the Nobel Prize in Physics in 2004 for work he did as a graduate student. He was among the earliest MacArthur fellows, and has won many awards both for his scientific work and his writing. He is the author of A Beautiful Question, The Lightness of Being, Fantastic Realities, Longing for the Harmonies, and hundreds of articles in leading scientific journals. His "Wilczek's Universe" column appears regularly in the Wall Street Journal. Wilczek is the Herman Feshbach Professor of Physics at the Massachusetts Institute of Technology, founding director of the T. D. Lee Institute and chief scientist at the Wilczek Quantum Center in Shanghai, China, and a distinguished professor at Arizona State University and Stockholm University. (shrink)

How important is luck in economic success? No question more reliably divides conservatives from liberals. As conservatives correctly observe, people who amass great fortunes are almost always talented and hardworking. But liberals are also correct to note that countless others have those same qualities yet never earn much. In recent years, social scientists have discovered that chance plays a much larger role in important life outcomes than most people imagine. In Success and Luck, bestselling author and New York Times economics (...) columnist Robert Frank explores the surprising implications of those findings to show why the rich underestimate the importance of luck in success--and why that hurts everyone, even the wealthy. Frank describes how, in a world increasingly dominated by winner-take-all markets, chance opportunities and trivial initial advantages often translate into much larger ones--and enormous income differences--over time; how false beliefs about luck persist, despite compelling evidence against them; and how myths about personal success and luck shape individual and political choices in harmful ways. But, Frank argues, we could decrease the inequality driven by sheer luck by adopting simple, unintrusive policies that would free up trillions of dollars each year--more than enough to fix our crumbling infrastructure, expand healthcare coverage, fight global warming, and reduce poverty, all without requiring painful sacrifices from anyone. If this sounds implausible, you'll be surprised to discover that the solution requires only a few, uncontroversial steps. Compellingly readable, Success and Luck shows how a more accurate understanding of the role of chance in life could lead to better, richer, and fairer economies and societies. (shrink)

Das deutsche Gesundheitswesen steht durch die schnell steigende Anzahl an CO- VID-19-Erkrankten vor erheblichen Herausforderungen. In dieser Krisensituation sind alle Beteiligten mit ethischen Fragen konfrontiert, beispielsweise nach gerech- ten Verteilungskriterien bei begrenzten Ressourcen und dem gesundheitlichen Schutz des Personals angesichts einer bisher nicht therapierbaren Erkrankung. Daher werden schon jetzt klinische und ambulante Ethikberatungsangebote verstärkt mit Anfragen nach Unterstützung konfrontiert. Wie können Ethikberater*innen Entscheidungen in der Krankenversorgung im Rahmen der COVID-19-Pandemie unterstützen? Welche Grenzen von Ethikberatung sind zu beachten? Bislang liegen hierzu (...) noch wenige praktische Erfahrungen vor. Angesichts der dynamischen Entwicklung erscheint es der Akademie für Ethik in der Medizin (AEM) wichtig, einen Diskurs über die angemessene Rolle der Ethikberatung bei der Bewältigung der vielfachen Heraus- forderungen durch die COVID-19-Pandemie zu führen und professionelle Hinweise zu geben. Mit dem vorliegenden Diskussionspapier möchte die AEM einen Beitrag zur Beantwortung wesentlicher Fragen leisten, die sich für die Ethikberatung in den verschiedenen Bereichen des Gesundheitswesens stellen. Sie regt an, diesen Dis- kurs weiter zu führen und hat ein Online-Forum (s. unten) eingerichtet, in dem Ethikberater*innen ihre Erfahrungen teilen und die professionelle Selbstreflexion der Ethikberatung in Pandemiezeiten mit Anregungen fördern können.

John Dewey's Experience and Education is an important book, but first-time readers of Dewey's philosophy can find it challenging and not meaningfully related to the contemporary landscape of education. Jeff Frank's Teaching in the Now aims to reanimate Dewey's text--for first-time readers and anyone who teaches the text or is interested in appreciating Dewey's continuing significance--by focusing on Dewey's thinking on preparation. Frank, through close readings of Dewey, asks readers to wonder: How much of what we justify as (...) preparation in education is actually necessary? That is, every time we catch ourselves telling a student--you need to learn this in order to do something else--we need to stop and reflect. We need to reflect, because when we always justify the present moment of a student's education in terms of what will happen in the future, we may lose out on the ability to engage students' attention and interest now, when it matters. Dewey asks his readers to trust that the best way to prepare students for an engaging and productive future is to create the most engaging and productive present experience for students. We learn to live fully in the future, only by practicing living fully in the present. Although it can feel scary to stop thinking of the work of education in terms of preparation, when educators reclaim the present for students, new opportunities--for teachers, students, schools, democracy, and education--emerge. Teaching in the Now explores these opportunities in impassioned and engaging prose that makes Experience and Education come alive for readers new to Dewey or who have taught and read him for many years.

The once-lost introduction to the philosophy of science by Philipp Frank (1884-1966), a leading member of the Vienna circle of philosophers and biographer of Albert Einstein.

We generalize Frécon’s construction of the inevitable radical to groups in stable and even simple theories.

Frank Mitjans is an architect who has worked in London since 1976. He was introduced to the significance of the figure of St. Thomas More by Andrés Vázquez de Prada, author of the biography, Sir Tomás Moro, Lord Canciller de Inglaterra. In 1977 Vázquez de Prada invited Mitjans to visit with him the Thomas More Exhibition at the National Portrait Gallery, which stimulated his interest in representations of More, his family and his friends. Since August 2002 he has given (...) many presentations and talks on the topography of More’s London to groups of students and other interested people in Britain, Ireland, and Sweden. Frank Mitjans, architecte qui travaille à Londres depuis 1976, fut initié au personnage de Saint Thomas More par Andrés Vázquez de Prada, auteur de la biographie Sir Tomás Moro, Lord Canciller de Inglaterra. En 1977 Vázquez de Prada l’invita à l’accompagner dans sa visite de l’exposition Thomas More à la National Portrait Gallery, évènement qui aiguisa son intérêt pour les représentations de More, de sa famille et de ses amis. Depuis août 2002 il a régulièrement fait des présentations et des exposés à des groupes d’étudiants et d’autres en Grande-Bretagne, Irlande et Suède au sujet de la topographie du Londres de Thomas More. The recent exhibitions of the works of Holbein in London and Basel, and scholarly publications such as Holbein and England, have rekindled interest in the Portrait of Thomas More and his Family, and in the late sixteenth-century versions of Holbein’s presumed lost original. The present paper analyses the differences between the sixteenth-century versions and Holbein’s 1527 composition sketch, and concludes that the sketch is a more reliable witness to Holbein’s lost painting than the later versions, as well as the only authentic witness to More’s intentions; though anything we learn from the drawing must be checked against what we know from More’s letters and writings and other biographical data. From the later versions, however, and in particular from the references to Seneca on them, we can learn about those who commissioned them and England’s peculiar historical circumstances. (shrink)

An infinite field with only countably many pure types is algebraically closed.

We define the notion of generic for an arbitrary subgroup H of a stable group, and show that H has a definable hull with the same generic properties. We then apply this to the theory of stable fields.

This article addresses the extent and ways in which gender inequality in the newspaper coverage of arts and culture has changed in France, Germany, the Netherlands, and the United States, 1955-2005. Through a quantitative content analysis, we mapped all articles that appeared in two elite newspapers in each country in four sample years 1955, 1975, 1995, and 2005. First, despite increasing women’s employment in arts and culture and a quantitative feminization of journalism, elite newspaper coverage of women in arts and (...) culture has hardly changed, making up about 20-25 percent consistently over the last 50 years. Second, our results show surprisingly few cross-national differences in the amount of the newspaper coverage devoted to women in arts and culture. Third, although women are underrepresented in the coverage of all artistic genres, there is some evidence of horizontal sex segregation—particularly in architecture and modern dance and fashion —as well as vertical sex segregation—in that attention to women has increased in “highbrow” genres that have declined in status. Finally, as the status of an actor type increases from laymen to artistic directors, the proportion of women decreases in newspaper attention to arts and culture. (shrink)

More's Latin reply to Bugenhagen, given here with a facing English translation, is a comparatively brief but intense rebuttal of the principal points of Lutheran teaching concerning scripture ant tradition, faith and works, grace and free will, clerical celibacy, and the sacraments. It presents arguments elaborated at much greater length in More's other polemical works. _Supplication of Souls_ refutes _A Supplication for the Beggars_, an anticlerical pamphlet by Simon Fish which Henry VIII seems to have regarded with some favor. More (...) places his response in the mouths of the souls in purgatory. In the first book, he contemptuously demolished Fish's loose railery with accurate statistics and historical analysis. In the second, he defends the traditional doctrine of purgatory with brief arguments drawn from reason and a detailed analysis of scriptural passages. _Letter against Frith_ answers John Frith's Zwinglian arguments against the physical presence of Christ in the more. Written to an unknown correspondent, it is the briefest and mildest of More's polemical works and anticipates arguments presented moer elaborately in More's _The Answer to a Poisoned Book_. Besides full introductions and commentaries, a glossary, and an index, this volume contains seven appendices giving the works to which More is replying and other thematic, historical, and bibliographical matter closely related to the three works by More.

Ever since Kant, mainstream moral philosophy has been more or less animated by the mission of discovering inescapable law-like rules that would provide a binding justification for morality. Recently, however, more and more authors have started to question a) whether this is possible, and b) what could this project, after all, achieve? An alternative vision of the task of moral philosophy starts from the pragmatic idea that philosophizing begins and ends in the actual human experience. It leads into a view (...) where morality is seen as a ‘social technology’ that aims to make living together possible, and strengthen people’s capability to live a good life within a society. Moral rules, then, are tools that we use to influence our behavior for the better. The role of moral philosophy is, accordingly, to develop further our moral tools, to propose solutions that enhance people’s capabilities to live good lives. In other words, moral philosophers become ethical engineers that use their expertise in ethical topics to criticize existing ‘moral technology’ and construct new concepts and theories that better answer the current challenges for living a good life.

Qu'est-ce qu'un 'philosophe', au regard de l'histoire et singulièrement du XXIe siècle? Frank Pierobon, en s'appuyant sur son propre parcours et aussi sur ses dix années d'engagement dans la riche aventure des Matins-Philo à Bruxelles, tente d'apporter une réponse située à la question. Loin des imageries populaires, il fait du philosophe un homme de métier et de savoir-être dont toute l'existence oscillerait entre la création de concepts et, en même temps, une quête incessante du désir de sens. Un texte (...) court et fulgurant qui redit que nul n'est dispensé de philosopher. (shrink)

Plato: The Timaeus There is nothing easy about the Timaeus. Its length, limited dramatic discourse, and arid subject-matter make for a dense and menacing work. But make no mistake, it is a menacing work of great subtly and depth. Cosmology has traditionally received the bulk of scholarly attention. No less important, however, are the dialogue’s … Continue reading Plato: The Timaeus →.
