Combining testimonial reports from independent and partially reliable information sources is an important epistemological problem of uncertain reasoning. Within the framework of Dempster–Shafer theory, we propose a general model of partially reliable sources, which includes several previously known results as special cases. The paper reproduces these results on the basis of a comprehensive model taxonomy. This gives a number of new insights and thereby contributes to a better understanding of this important application of reasoning with uncertain and incomplete information.

Theoretical Laws and Normative Rules: Kant and Bolzano's Views on Logic'"1" Anita Von Duhn, Genf Does logic instruct us how to think correctly? ...

In everyday life, as well as in science, we have to deal with and act on the basis of partial (i.e. incomplete, uncertain, or even inconsistent) information. This observation is the source of a broad research activity from which a number of competing approaches have arisen. There is some disagreement concerning the way in which partial or full ignorance is and should be handled. The most successful approaches include both quantitative aspects (by means of probability theory) and qualitative aspect (by (...) means of graphical or causal models or logic). Some of these approaches have important impacts on various disciplines including philosophy, computer science, statistics, mathematics, physics, and social science. Most notably, the relation between causal and probabilistic information is a topic of interest in all of these fields. The general question of how uncertainty is related to ignorance, and the connection thereof to causality, have been the key topics of the international summer school at the University of Konstanz, Germany, in August 2004. This was the third event in a series of summer schools organized by the interdisciplinary research group “Philosophy, Probability, and Modeling”. The group was in operation from September 1st, 2001, until August 31, 2005. The first summer school, held in September 2002, focused on the application of probability theory to topics of philosophical interest. Problems and questions that arise when probabilistic models and techniques are being applied in the special sciences were then discussed during the second summer school, held in July 2003. The fourth and final event in the series, in August 2005, was devoted to philosophical questions related to the application and interpretation of probabilities in physics. Each of the four summer schools attracted 40–50 people from many different countries. It was an inspiring forum for an interdisciplinary discussion among researchers and students from many different areas. This special issue collects a selection of the invited and contributed papers presented at the summer school in 2004. We acknowledge the generous support of the Center for Junior Research Fellows at the University of Konstanz, the Gesellschaft für analytische Philosophie e.V., the Centre for Philosophy of Natural and Social Science at the London School of Economics, the Alexander von Humboldt Foundation, the Federal Ministry of Education and Research and the Program for the Investment in the Future (ZIP) of the German Government through a Sofja Kovalevskaja Award. We thank the referees of the papers for their work, and James Moor for his interest in dedicating a special issue of this journal to Causality, Uncertainty and Ignorance. (shrink)

Previous reports have demonstrated that the comprehension of sentences describing motion in a particular direction (toward, away, up, or down) is affected by concurrently viewing a stimulus that depicts motion in the same or opposite direction. We report 3 experiments that extend our understanding of the relation between perception and language processing in 2 ways. First, whereas most previous studies of the relation between perception and language processing have focused on visual perception, our data show that sentence processing can be (...) affected by the concurrent processing of auditory stimuli. Second, it is shown that the relation between the processing of auditory stimuli and the processing of sentences depends on whether the sentences are presented in the auditory or visual modality.

Unter dem Eindruck einer "Renaissance des Religiösen" einerseits und der zunehmenden Politisierung von Religionen andererseits rückt die Verhältnisbestimmung von Politik und Religion im staatlichen wie im internationalen Kontext verstärkt in den Fokus des politischen und gesellschaftlichen Interesses. In den letzten Jahren trägt auch die politische Philosophie dieser Situation vermehrt Rechnung, was sich in einer steigenden Zahl von Veröffentlichungen zu diesem Thema niederschlägt. Dabei kann sie auf eine reiche Tradition philosophischer Modelle zum Neben-, Mit- oder Gegeneinander von Politik und Religion zurückblicken. (...) Was in dieser Diskussion bisher jedoch fehlt, ist eine differenzierte Darstellung der für die Verhältnisbestimmung von Philosophie, Politik und Religion klassischen Modelle, angefangen von der griechischen Antike bis in die Liberalismus-Kommunitarismus-Debatte des ausgehenden letzten Jahrhunderts. Diese Lücke schließt der vorliegende Band: In 15 Beiträgen namhafter Experten werden klassische Modelle der Verhältnisbestimmung von Philosophie, Politik und Religion, beginnend mit Platon bis hin zu Charles Taylor, eingehend behandelt.

Population counts and longitude and latitude coordinates were estimated for the 50 largest cities in the United States by computational linguistic techniques and by human participants. The mathematical technique Latent Semantic Analysis applied to newspaper texts produced similarity ratings between the 50 cities that allowed for a multidimensional scaling (MDS) of these cities. MDS coordinates correlated with the actual longitude and latitude of these cities, showing that cities that are located together share similar semantic contexts. This finding was replicated using (...) a first‐order co‐occurrence algorithm. The computational estimates of geographical location as well as population were akin to human estimates. These findings show that language encodes geographical information that language users in turn may use in their understanding of language and the world. (shrink)

The studies in this book set out to examine the labile resonances of phenomenology and art in Michel Henry, by examining the different figures of movement given to the concept of the aesthetic by the philosopher. They are preceded by one of Michel Henry’s own texts. Les études qui composent ce livre proposent d’interroger les résonances labiles de la phénoménologie et de l’art chez Michel Henry, en examinant les différentes figures du déplacement imprimé par le philosophe au concept d’esthétique. Le (...) tout est précédé d’un texte de Michel Henry. (shrink)

In the late 1940s and early 1950s, there emerged a radically new kind of music based on recorded environmental sounds instead of sounds of traditional Western musical instruments. Centered in Paris around the composer, music theorist, engineer, and writer Pierre Schaeffer, this became known as musique concrète because of its use of concrete recorded sound fragments, manifesting a departure from the abstract concepts and representations of Western music notation. Furthermore, the term sound object was used to denote our perceptual images (...) of such fragments. Sound objects and their features became the focus of an extensive research effort on the perception and cognition of music in general, remarkably anticipating topics of more recent music psychology research. This sound object theory makes extensive use of metaphors, often related to motion shapes, something that can provide holistic representations of perceptually salient, but temporally distributed, features in different kinds of music.

Which theories of Leibniz are still valid after post-modern critique? Using various methods, this work considers a new interpretation and views Leibniz's work from a different perspective. As such, the authors reconstruct Leibniz's viewpoints on tolerance and truth in light of his position and the influence of church politics. Furthermore, his strategy of differentiation between animal and human will be analyzed on its usefulness to current debate. Leibniz's theory of perception will also be contrasted to comparable theories of today. The (...) usual interpretations of his metaphysics based on substance will here be contrasted by a nature-based interpretation. German text. (shrink)

According to general relativity, we live in a four-dimensional curved universe. Since the human mind cannot visualize those four dimensions, a popular analogy compares the universe to a two-dimensional rubber sheet distorted by massive objects. This analogy is often used when teaching GR to upper secondary and undergraduate physics students. However, physicists and physics educators criticize the analogy for being inaccurate and for introducing conceptual conflicts. Addressing these criticisms, we analyze the rubber sheet analogy through systematic metaphor analysis of textbooks (...) and research literature, and present an empirical analysis of upper secondary school students’ use and understanding of the analogy. Taking a theoretical perspective of embodied cognition allows us to account for the relationship between the experiential and sensory aspects of the metaphor in relation to the abstract nature of spacetime. We employ methods of metaphor and thematic analysis to study written accounts of small groups of 97 students who worked with a collaborative online learning environment as part of their regular physics lessons in five classes in Norway. Students generated conceptual metaphors found in the literature as well as novel ones that led to different conceptions of gravity than those held by experts in the field. Even though most students showed awareness of some limitations of the analogy, we observed a conflict between students’ embodied understanding of gravity and the abstract description of GR. This conflict might add to the common perception of GR being counterintuitive. In making explicit strengths and weaknesses of the rubber sheet analogy and learners’ conceptual difficulties, our results offer guidance for teaching GR. More generally, these findings contribute to the epistemological implications of employing specific scientific metaphors in classrooms. (shrink)

Frauen sind ängstlich, Männer sollen mutig sein. Bei dieser Behauptung handelt es sich zwar nicht um ein wörtliches Zitat von Kant, doch gibt sie seine Auffassung recht genau wieder. Und sie kann in gewisser Weise als geradezu paradigmatisch für die Geschlechterspezifik von Emotionen stehen, so wie Kant sie sieht. Nun ließe sich einwenden, bei Ängstlichkeit und Mut handele es sich nicht um Emotionen, sondern um Charaktereigenschaften. Das soll natürlich nicht bestritten werden. Doch sind sie ebenso wie zahlreiche andere, etwa die (...) Schamhaftigkeit, eng mit den entsprechenden Emotionen verbunden: sich ängstigen, sich schämen. Zudem benutzt Kant des Öfteren den die Charaktereigenschaft bezeichnenden Ausdruck, meint aber das Gefühl. Das ist insbesondere in von ihm selbst nicht publizierten Notizen, etwa den Reflexionen der Fall. Das gleiche gilt für die von Studierenden eilig mitgeschriebenen Vorlesungen, die oft nur in Form weiterer Nachschriften vorliegen. Hierzu ist anzumerken, dass sowohl Kants Notizen oder den Reflexionen finden) als auch die Mit- und Nachschriften der Vorlesungen seine Auffassung möglicherweise in geringerer Authentizität wiedergeben als die von ihm selbst publizierten Schriften. Das wird an Ort und Stelle nicht jeweils eigens erwähnt, sondern ist stets mitgedacht. Denn ich werde zur Untersuchung der Geschlechterspezifik von Emotionen bei Kant wiederholt sowohl auf die Bemerkungen und Reflexionen als auch auf Vorlesungsnachschriften zurückgreifen müssen, sind sie doch weitaus ergiebig als seine Schriften, von denen nur die Beobachtungen und die Anthropologie in pragmatischer Hinsicht ausführliche Überlegungen zu unserem Thema enthalten.

Open discourses and the free formation of opinions through unfettered information flows and communicated diversity of opinion are unthinkable without independent media and essential prerequisites for a functioning democracy. Notwithstanding the importance of the linkage between media and democracy, there is no harmonized framework addressing this issue. By adopting a legal perspective, this study shall outline existing and emerging regulations, with a particular focus on broadcast, print, and online media Two regulatory tiers are distinguished: At the international level, the establishment (...) of aWorld Information Order as well as the human rights perspective intrinsic to the subject matter will be addressed. At the national level, legal approaches to particular tensions accompanying state regulation of the media will be examined. (shrink)
