You know that a two-child family has a son. What is the probability that the family has two sons? And what is this probability if you know that the family has a son born on a Tuesday? The former question has been widely discussed previously. The latter adds a new puzzling twist to the situation. In both cases the answer should depend on the specifics of the assumed underlying procedure by which the given information has been obtained. Quantitative analysis, assuming (...) one scenario, shows that the information on the son's day of birth changes the target probability. However, the relevance of being born on Tuesday to the question of the children's genders seems bizarre, since the same would be true for any other day. This apparent paradox is further probed in an attempt to alleviate the ensuing psychological difficulty. (shrink)

The term “exchange paradox” refers to a situation in which it appears to be advantageous for each of two holders of an envelope containing some amount of money to always exchange his or her envelope for that of the other individual, which they know contains either half or twice their own amount. We review several versions of the problem and show that resolving the paradox depends on the specifics of the situation, which must be disambiguated, and on the player's beliefs. (...) The latter psychological variables are part and parcel of the resolution. Assuming reasonable subjective distributions, exchanging cannot always be advantageous for both players. We suggest several deep-rooted psychological reasons for the considerable difficulty people demonstrably have in dealing with this problem. Implicit widespread and compelling assumptions—that affect judgement in diverse contexts—obstruct the solution. Analysing this paradox underscores the close connection between psychology and probability theory. (shrink)

Falk Wunderlich präsentiert einen grundlegend neuen Ansatz zum Verständnis der Kant'schen Bewusstseinstheorie. Im ersten Teil bietet er eine detaillierte Rekonstruktion der bewusstseinstheoretischen Diskussionen des 18. Jahrhunderts. Im Mittelpunkt steht dabei die Rekonstruktion des Geflechts von Diskussionen, in dessen Kontext sich Kants Überlegungen bewegen. Auf diese zeitgenössischen Debatten werden im zweiten Teil Kants bewusstseinstheoretische Ansätze bezogen. Der Autor vertritt die These, dass Kant die zeitgenössischen Standardansichten über Bewusstsein, Apperzeption und Selbstbewusstsein entgegen dem Anschein nur einschränkt modifiziert und ihre begrifflichen Grundlagen (...) beibehält. Schließlich wird vor dem Hintergrund dieser Kontextualisierung eine alternative Interpretation der transzendentalen Deduktion entwickelt. (shrink)

This book offers a unique perspective on Zionism. The author, a geneticist by training, focuses on science, rather than history. He looks at the claims that Jews constitute a people with common biological roots. An argument that helps provide justification for the aspirations of this political movement dedicated to the return of the Jewish people to their homeland. His study explores two issues. The first considers the assertion that there is a biology of the Jews. The second deals with attempts (...) to integrate this idea into a consistent history. Both issues unfolded against the background of a romantic national culture of Western Europe in the 19th century: Jews, primarily from Eastern Europe, began to believe these notions and soon they took the lead in the re-formulation of Jewish and Zionist existence. The author does not intend to present a comprehensive picture of the biological literature of the origins of a people and the blood relations between them. He also recognizes that the subject is emotionally-loaded. The book does, however, present a profound mediation on three overlapping questions: What is special or unique to the Jews? Who were the genuine Jews? And how can one identify Jews? This volume is a revised and edited English version of Tzionut Vehabiologia shel Hayehudim, published in 2006. (shrink)

Das Verhältnis von Glauben und Denken kann als Angelpunkt und Motor der neuzeitlichen Geschichte begriffen werden. Walter Falks Werk zeigt in singulärer Weise, auf welchen teilweise verdrängten Fundamenten der wissenschaftliche Fortschrittsglaube beruhte und bietet eine kritische Analyse der 'Legitimität der Neuzeit', die ebenbürtig neben den großen Arbeiten von Hans Blumenberg, Michel Foucault oder Joachim Ritter bestehen kann. Walter Falk geht anhand der Metapher von der Weltmaschine, die sich seit 1770 in verschiedenen Texten und in Modifikationen findet, der Fortschrittsgeschichte und (...) ihrer Kritiker nach. So entwirft er, vor dem Hintergrund einer neuartigen Epochendeutung ein geistesgeschichtliches Panorama, das von Comte und Schlegel und Kleist bis zu Kafka und Heidegger reicht. Das Buch zeigt vor dem Hintergrund der Wissenschaftsgeschichte des 20. Jahrhunderts, wie die Gestalt des personalen Gottes in den großen geistes- und naturwissenschaftlichen Innovationsschüben der Moderne zunehmend wieder in den Blick genommen wurde. Dabei erfahren die Ansätze von Foucault, Konrad Lorenz oder René Girard eine eigenwillige und profilierte, Natur- und Kulturwissenschaften innovativ miteinander verbindende Deutung. Das eigentliche Interesse des Buches ist aber nicht historischer Natur. Falk demonstriert eindrucksvoll, wie Glauben und Denken in der Gegenwart zugleich differenziert und integriert werden müssen, um auf der Höhe der Moderne wieder fruchtbar in ein Gespräch kommen zu können.

The book also explains how devices such as lasers or particle accelerators work. (shrink)

One would hardly be a human being if the good of others, or of society at large, could not weigh with one as a cogent reason for doing what will promote goodness. So one has not fully learned about living like a rational and moral being unless one has learned to appreciate that one ought to do things out of regard for others, and not only out of regard for oneself. In the first place, not everything done for oneself is (...) done for reasons of prudence. That one ought to insure one's house, save for one's old age, not put all one's money into one venture, are precepts of prudence. But it is not a precept of prudence, though it may be a good precept that someone ought to undergo a dangerous operation as a long shot to restoring his health rather than linger under a disability forever after.

In two eye-tracking studies we investigated the influence of Mandarin numeral classifiers – a grammatical category in the language – on online overt attention. Mandarin speakers were presented with simple sentences through headphones while their eye-movements to objects presented on a computer screen were monitored. The crucial question is what participants look at while listening to a pre-specified target noun. If classifier categories influence Mandarin speakers' general conceptual processing, then on hearing the target noun they should look at objects that (...) are members of the same classifier category – even when the classifier is not explicitly present. The data show that when participants heard a classifier they shifted overt attention significantly more to classifiermatch objects than to distractor objects, but when the classifier was not explicitly presented in speech, overt attention to classifier-match objects and distractor objects did not differ. This suggests that although classifier distinctions do influence eye-gaze behavior, they do so only during linguistic processing of that distinction and not in moment-to-moment general conceptual processing.

Developments in the sequencing of whole genomes and in simultaneously surveying many thousands of transcription and translation products of specific cells have ushered in a conceptual revolution in genetics that rationally introduces top-down, holistic analyses. This emphasized the futility of attempts to reduce genes to structurally discrete entities along the genome, and the need to return to Johannsen's definition of a gene as 'something' that refers to an invariant entity of inheritance and development. We may view genes either as generic (...) terms for units of inheritance whose referents are pragmatic ad hoc and context-dependent, or as (epistemologically) representing entities of cell functions. It is cellular functions that determine the structural referents along the DNA. Structures that happened to secure specific functions that were essential for or conducive to the survival of cells were selected for. With natural selection being the etiological background of genes as functions, genes obtain again their theoretical role as intervening variables, abstractive variables that purely 'summarize' characters. The importance of DNA sequences is that of all possible phenotypes these are the most basic ones from which we can read off the genotype directly. (shrink)

Interprofessional collaboration involves some kind of knowledge sharing, which is essential and will be important in the future in regard to the opportunities and challenges in practices for delivering safe and effective health care. Nursing assistants are seldom mentioned as a group of health care workers that contribute to interprofessional collaboration in health care practice. The aim of this ethnographic study was to explore how the nursing assistants’ knowledge can be shared in a team on a spinal cord injury rehabilitation (...) ward. Using a sociomaterial perspective on practice, we captured different aspects of interprofessional collaboration in health care. The findings reveal how knowledge was shared between professionals, depending on different kinds of practice architecture. These specific cultural–discursive, material–economic, and social–political arrangements enabled possibilities through which nursing assistants’ knowledge informed other practices, and others’ knowledge informed the practice of nursing assistants. By studying what health care professionals actually do and say in practice, we found that the nursing assistants could make a valuable contribution of knowledge to the team. (shrink)

Diese Arbeit stellt Bertrand Russell als politischen Menschen vor und untersucht Erschließungspotentiale für die politische Bildung von heute. Hierbei sind Leitfragen von Bedeutung, wie: Welche Ereignisse bedingten Russells Lebensweg, wie kam er zu seinen politischen Ansichten und seinem Engagement? Wie lässt sich seine politische Philosophie verorten und systematisieren? Wie sieht seine pädagogische Konzeption aus und wie steht diese im Zusammenhang mit seinen politischen Überzeugungen? Wie ist Russells Wirkungsgeschichte zu beurteilen? Inwiefern eröffnen sich mit der Person Russell, seinen Schriften und mit (...) seinem politischen Handeln Erschließungschancen für politische Bildung? Inwieweit kann Russell als Vorbild für einen politischen Aktivbürger dienen? (shrink)

The writings of Weber and Taylor have some strong affinities. Both start from the anthropological idea that man evaluates his position in the world and constitutes the social world by values. Their analyses of values aim at an understanding of those intersubjective meanings that have constituted western modernity. But, at the same time, their anthropological starting point leads to different interpretations of modernity. Historically, both argue that rationalization (as instrumental rationality) is one of the most influential Kulturbedeutung of modernity. Weber's (...) thesis of rationalization is, however, entangled in a paradox. Overemphasizing the rationalized elements of modernity, he fails scientifically to grasp certain counter-movements in modernity, such as individuation, subjectivity and new life forms. Taylor, investigating the moral sources of expressivism, shows that these life forms are an inherent part of modernity. Yet his method of articulating the sources of modernity is insufficient to transform it towards a causal explanation of behaviour in everyday life. (shrink)

This article explores the tensions between geopolitics and human rights under present conditions of world politics. It takes notes of the rise of human rights as a discourse in international law, and draws attention to the use of this discourse by powerful states, especially the United States, to validate non-defensive uses of force. It also notes the role of the media in facilitating the geopolitical agenda associated with exerting pressure on some conditions but exempting other situations as serious or more (...) so . This article also discusses the reliance on the human rights discourse by oppressed groups and by countries in the South, and the emergence of a counter-hegemonic tradition in human rights that challenges geopolitical projects in a variety of settings. The main conclusion is that neither an uncritical endorsement nor a cynical dismissal of human rights is appropriate at this time.Keywords: human rights; geopolitics; hegemony; counter-hegemony; international law.

Marr's levels of analysis—computational, algorithmic, and implementation—have served cognitive science well over the last 30 years. But the recent increase in the popularity of the computational level raises a new challenge: How do we begin to relate models at different levels of analysis? We propose that it is possible to define levels of analysis that lie between the computational and the algorithmic, providing a way to build a bridge between computational- and algorithmic-level models. The key idea is to push the (...) notion of rationality, often used in defining computational-level models, deeper toward the algorithmic level. We offer a simple recipe for reverse-engineering the mind's cognitive strategies by deriving optimal algorithms for a series of increasingly more realistic abstract computational architectures, which we call “resource-rational analysis.”.

In this wide-ranging and multidisciplinary volume, leading scholars, activists, journalists, and public figures deliberate about the creative and critical potential of public imagination in an era paradoxically marked by intensifying globalization and resurgent nationalism. Divided into five sections, these essays explore the social, political, and cultural role of imagination and civic engagement, offering cogent, ingenious reflections that stand in stark contrast to the often grim rhetoric of our era. Short and succinct, the essays engage with an interconnected ensemble of themes (...) and issues while also providing insights into the specific geographical and social dynamics of each author's national or regional context. Part 1 introduces the reader to theoretical reflections on imagination and the public sphere; Part 2 illustrates dynamics of public imagination in a diverse set of cultural contexts; Part 3 reflects in various ways on the urgent need for a radically transformed public and civic imagination in the face of worldwide ecological crisis; Part 4 suggests new societal possibilities that are related to spiritual as well as politically revolutionary sources of inspiration; Part 5 explores characteristics of present and potentially emerging global society and the existing transnational framework that could provide resources for a more humane global order. Erudite and thought-provoking, On Public Imagination makes a vital contribution to political thought, and is accessible to activists, students, and scholars alike. (shrink)

In this two-part essay I develop a theory of natural signs. Since even primordial signs signify values, in the first part I develop the theory’s valuative aspect. Goods are as primary in nature as facts are, and together facts and values generate semeiosis in all life without excess extrapolation from human psychology. To ward off over-extrapolating on values, I defend a major discontinuity between man and nature on the goods of ethics. In the essay’s second part I develop the semeiotic (...) dimensions of the negative feedback model of purposive systems. I provide tests for the truth and falsity of the primitive representations in these systems. I account for the holism of representational systems and their non-extensionality, and I define functions. I solve this important definitional problem by inverting the usual mode of thinking: Functions do not explain signs; signs explain functions. Finally I defend this theory’s way of understanding the continuity between human beings and the rest of living nature against several criticisms. (shrink)

‘Ifs’ come washed or unwashed. The washed ifs are embedded in precise theories: the constantly strict implication of deductive inference, the variably strict implication of ‘nearness’ conditionals, and statements of conditional probability. By a nearness conditional I mean the common part of Stalnaker's and D. Lewis's theory of counterfactual conditionals, which depends on a notion that possible worlds are more or less near to each other, as a measure of their over-all similarity to each other.

According to philosophical naturalism, the main anti-naturalism in philosophy derives from Kant and depends on transcendental arguments, which are invalid or polemically toothless. Many of naturalism's characteristic features follow from this repudiation of Kantian method. Anti-naturalists should be aware that the rationale for naturalism depends on this attack on their own position. There remains for philosophy a distinctively philosophical role that depends on the indexical element in our thought, the role of elaborating a scientific worldview.
