According to the predictive coding theory of psychosis, hallucinations and delusions are explained by an overweighing of high-level prior expectations relative to sensory information that leads to false perceptions of meaningful signals. However, it is currently unclear whether the hypothesized overweighing of priors represents a pervasive alteration that extends to the visual modality and takes already effect at early automatic processing stages. Here, we addressed these questions by studying visual perception of socially meaningful stimuli in healthy individuals with varying degrees (...) of psychosis proneness. In a first task, we quantified participants’ prior for detecting faces in visual noise using a Bayesian decision model. In a second task, we measured participants’ prior for detecting direct gaze stimuli that were rendered invisible by continuous flash suppression. We found that the prior for detecting faces in noise correlated with hallucination proneness as well as delusion proneness. The prior for detecting invisible direct gaze was significantly associated with hallucination proneness but not conclusively with delusion proneness. Our results provide evidence for the idea that overly strong high-level priors for automatically detecting socially meaningful stimuli might constitute a processing alteration in psychosis. (shrink)

This book is the first to explore in detail the role that symbolic representation plays in the architecture of Kant's philosophy. Symbolic representation fulfills a crucial function in Kant's practical philosophy because it serves to mediate between the unconditionality of the categorical imperative and the inescapable finiteness of the human being. By showing how the nature of symbolic representation plays out across all areas of the practical philosophy - moral philosophy, legal philosophy, philosophy of history and philosophy of religion - (...) Heiner Bielefeldt offers a unique perspective on how these various facets of Kant's philosophy cohere. (shrink)

: The paper discusses the concepts of obligation and moral evidence in Mendelssohn’s and Kant’s prize essays. I argue that Mendelssohn departs in significant ways from Christian Wolff’s position, and that Kant intends to overcome Wolffian philosophy with Newtonian methodology while still owing a lot to Wolff and to the project of an ethics within the limits of metaphysics. Although quite akin to Francis Hutcheson’s philosophy, it becomes clear that Kant intended to lay the foundation of an innovative concept of (...) obligation, which shares some similarities with Christian August Crusius’s interpretation of it.

This original new work takes a sharply focused look at Berkeley's ontology and provides a fuller understanding of the relationship between, on the one hand, Berkeley's nominalism and antiabstractionism and, on the other, his principal arguments for idealism and his attempts to square his idealism with common sense. Drawing heavily on detailed textual analysis, historical context, and careful examination of the work of other scholars, Muehlmann challenges, modifies, rejects, and exploits some well-established interpretations of Berkeley's philosophy.

ZusammenfassungVon Vertragsärzten in ihren Praxen angebotene oder hier von Patienten nachgefragte "individuelle Gesundheitsleistungen" sind in unserem Gesundheitswesen zu einer häufigen Erscheinung geworden. Es hat sich ein "zweiter Gesundheitsmarkt" mit einem erheblichen ökonomischen Potential entwickelt. Die Leistungen umfassen ein weites Spektrum; sie adressieren ganz unterschiedliche Gesundheitsstörungen, Ziele und Hoffnungen und sind extrem heterogen. Auch dies erschwert eine einheitliche Definition. Aus Patientensicht scheint das wichtigste Merkmal, dass IGeL vollständig privat bezahlt werden müssen. Der Beitrag diskutiert IGeL unter normativen Gesichtspunkten und adressiert 6 (...) Fragen: welche Risiken und Chancen beinhalten IGeL für das hergebrachte Bild des Arztes und seine Profession, das Verständnisder wissenschaftlichen Grundlagenärztlicher Untersuchungs- und Behandlungsmethoden, das Verständnis der Medizin und ihrer Ziele, die bisherige Rolle der Patienten, die Beziehung zwischen Arzt und Patient und das Bild der Gesetzlichen Krankenversicherung? Einerseits sind IGeL aus unterschiedlichen Gründen für Patienten und Vertragsärzte attraktiv. In Zeiten einer zunehmenden Regulierung der Medizin erhöhen sie Freiheitsgrade und Wahlmöglichkeiten beider Seiten. Andererseitshaben sie das Potential, vor allem die Rolleund Profession des ArztesimSystemderGKVund ihreWahrnehmungtiefgreifendzu verändern. Obsich der IGeL-Markt bei uns kontrollieren und regulieren lässt, ist eine zurzeit offene Frage. (shrink)

Bei transzendenten Erfahrungen treten Aspekte und Dimensionen der vertrauten Wirklichkeit hervor, die normalerweise verborgen sind. Gewohnte Deutungsmuster und Erklarungskategorien versagen. Kognitive Spannungen sind die Folge. Das Bedurfnis nach ihrer Losung fuhrt oft zu vorschnellen Interpretationen und Erklarungen oder gar zur apriorischen Abwertung und Ignorierung transzendenter Erfahrungen. Sorgfaltige und umsichtige wissenschaftliche Studien sind daher immer noch ein Desiderat. Die Beitrage basieren auf einer Ringvorlesung an der Universitat Basel. Sie thematisieren an einschlagigen Beispielen die Phanomenologie transzendenter Erfahrungen, ihre biographischen Wirkungen, ihr Zusammenspiel (...) mit kunstlerischem Schaffen und Erleben, die Schwierigkeit ihrer Deutung und Beurteilung und ihre Abwertung und Pathologisierung durch Aufklarung und Wissenschaft.

A recent paper by David Levy focuses on “utility enhancing consumption constraints.” Levy concludes by noting that his analysis stays within standard utility maximizing theory, in contrast to my analysis of rule-governed behavior which allows imperfect decisions that don't always maximize utility. I wish to show how our two theories can be integrated, thereby representing complementary, rather than conflicting, explanations. In the process, I argue that imperfect decisions are an essential factor in the stability of any rule that constrains freedom (...) of choice. I also briefly discuss certain intrinsic problems with achieving “self-stabilizing” rules applied to moral teachings. (shrink)

Twenty-first century agoras, unlike their historical counterparts, are not comprised of villages populated by individuals who know each other and share the same past, environment, and culture. Contemporary agoras are diverse and global. Their dialogue is often conducted across geographical and cultural boundaries. Additionally, they often address challenges and issues that are far more complex than those of the early agoras. This article seeks to identify such challenges and summarize a variety of appropriate dialogue methodologies.

Die Frage, ob und wie der universale Geltungsanspruch der Menschenrechte sich mit dem Pluralismus der Religionen und Kulturen vermitteln läßt, ist ein zentrales Thema innerhalb der gegenwärtigen Menschenrechtsdebatte. Die Kantische Philosophie kann einen Beitrag zu dieser Debatte leisten, indem sie dazu verhilft, einige vielfach beschworene Dichotomien kritisch auszuräumen, durch die die interkulturelle Verständigung über Menschenrechte nicht selten schon im Ansatz blockiert wird. Nach Kant zielt eine kosmopolitische rechtliche Rahmenordnung nicht auf globale Uniformierung, sondern auf die politisch-rechtliche Gestaltung der faktisch erreichten (...) und vermutlich irreversiblen politischen und wirtschaftlichen Globalisierung. Wenn menschenrechtliche Freiheit jedem einzelnen Menschen zukommt, so steht der darin implizierte Individualismus als ein genuin ethischer Individualismus keineswegs, wie oft behauptet, in Gegensatz zu kommunitären Ansprüchen auf Solidarität, sind doch Menschenrechte an der der Würde des Menschen als der inneren Quelle jeder moralischen Solidarität orientiert. Schließlich widerspricht die in der sittlichen Autonomie begründete Menschenwürde zwar einem politisch-rechtlich durchsetzbaren materialen Gottesrecht; sie ist gleichwohl aber offen für theologische Ausdeutungen der Menschenwürde über die anthropozentrische Perspektive hinaus.

Critical Rationalists have developed some concepts to clarify what it means to take a “critical rationalist” standpoint towards political matters. The “critical attitude as a way of life”, the application of realizability tests, the “law of unintended consequences” and the conception of “piecemeal technology” are introduced for this purpose. Our analysis tries to show that such doctrines do not provide a basis for a viable “critical rationalist” political theory. They at best offer a repertory of arbitrary arguments for the symbolic (...) use of politics. (shrink)

Transgenic mice constitute an entirely new dimension of mammalian molecular genetics. They allow us to observe genes at work in the intact organism. Virtually every sector of biomedical research is likely to be affected.

<I>Aesthetics in Sartre and Camus examines the ideas on aesthetics expressed in the oeuvres of the two French authors. The dispute that arose following the publication of Camus' <I>L'homme revolte and Sartre's criticism of Camus' book culminated in the break up of their friendship in 1952, thereby underlining the differences in the authors' thinking. But by observing the function and significance of art and freedom in their works, fundamental correspondences and areas of agreement are revealed in Sartre's and Camus' writings (...) and are analysed in the present study.".

This paper consists of a thorough examination of the russell-Wittgenstein controversy over identity. The early wittgenstein's comments on this issue are cryptic and obscure; yet one thing is obvious. His views on identity are partly, If not wholly a negative response to russell's. In unearthing the source of the controversy, I distinguish several senses of 'identity'. I then examine several texts of russell's showing that he fails to make these necessary distinctions. I conclude by demonstrating that wittgenstein's comments are designed (...) in part to rectify this mistake and in part to offer an illuminating analysis of his own. (shrink)

Human cloning is a main focus of current bioethical discussion. Involving the self-understanding of the human species, it has become one of the most debated topics in biomedical ethics, not only on the national, but also on the international level. This book brings together articles by bioethicists from several countries who address questions of human cloning within the context of different cultural, religious and regional settings against the background of globalizing biotechnology. It explores on a cross-cultural level the problems and (...) opportunities of global bioethics. (shrink)

This article objects to two major economistic shortcomings of Philippe Van Parijs’s Real Freedom for All: (1) Van Parijs claims that market prices are the best metric for equal real freedom. This is challenged. Market prices admittedly are the best instrument for distributive purposes at hand. They are, however, a means of transport for supply and demand contingendes. Hence market prices are to be considered as an insufficient metric for equal freedom. (2) Van Parijs claims that Real Freedom for All (...) is all there is to social justice. This claim is rejected. Despite its demanding egalitarian ambition, Real Freedom for All fails to protect a flourishing human life. Basic human rights like the right to social recognition and, in part, the right to health care are violated. Curiously even the right to autonomy is in want of full protection. These lacks are caused by the monetarism and the Straightforward market optimism of Real Freedom for All. (shrink)

Which Books by Teichmüller Did Nietzsche Have Access to? An Attempt at a Reconstruction. The question of which books by Gustav Teichmüller Nietzsche had available has not been satisfactorily clarified to this day. Drawing on sources not considered so far, including the correspondence between Teichmüller and Franz Overbeck and a list that Teichmüller kept about copies of his writings he had sent to colleagues and friends found in his Nachlass, I conclude that Nietzsche only had four books by Teichmüller at (...) his disposal (apart from the opusculum Ueber die Reihenfolge der platonischen Dialoge). Three of these were loans: Aristotelische Forschungen I from the University Library of Basel in the summer semester of 1870, Die Wirkliche und die scheinbare Welt, from Overbeck between late summer 1882 (at the earliest) and November 1885, and the Neue Studien zur Geschichte der Begriffe III also from Overbeck from October 1883 to November 1885. Only the Aristotelischen Forschungen II seem to have been Nietzsche’s personal property (since 1869). Although it is often assumed that Nietzsche also read other books by Teichmüller – e. g., the Studien zur Geschichte der Begriffe, the Neue Studien zur Geschichte der Begriffe II, and the two volumes of the Literarische Fehden im vierten Jahrhundert v. Chr. – they were most likely not available to Nietzsche. (shrink)

On the occasion of the 100th birthday of the physical chemist Kurt Schwabe the article presents an overview about Schwabe’s activities as president of the Saxon Academy of Science from 1965 to 1980. Main topics of this time which has to be solved by Schwabe were to ensure the further existence of the academy and to reach an agreement about the principles of cooperation between the Saxon Academy of Science and the Berlin Academy of Science as an agreement of equals.

Tendencies of secularization-religiosity decreases in Western societies since 1950-have been found abundantly in comparative survey research. They are taken as starting point to examine what the theory of secularization predicts and which predictions have been confirmed. It is shown that the three canonical theories of the change of religiosity-secularization, individualization, and market theory-are identical in their structure und can be integrated as the secularization theory. The secularization theory has been tested in cross-sectional and longitudinal designs, and by macro and multi-level (...) analyses-that is, cross-classfied in four forms. Neglecting cross-sectional macro analyses, there are only 11 publications within the three remaining forms. They confirm a negative effect of social differentiation throughout und a negative effect of cultural pluralization often. Yet they often fail to control for important micro impacts upon religiosity, such as denomination or parenthood. In sum, they show that the secularization theory is by no means disconfirmed, yet rarely tested. Keywords Longitudinal studies, differentiation, pluralization, determinants of religiosity, cohort succession, multi-level-analysis. (shrink)

This collection of fourteen interpretative essays on the philosophy of George Berkeley focuses specifically on Berkeley’s theory of the nature and variety of existing things. The collection is notable for containing the first four winners of the Turbayne International Berkeley Essay Prize. The seven essays in the first part, entitled “Idealism,” attempt to illuminate Berkeley’s notorious thesis that to be is to be perceived, that the _esse_ of sensible things is _percipi._ Most of the essays in this first part are (...) either direct or indirect responses to an influential interpretation of Berkeley’s idealism advanced thirty years ago by Edwin B. Allaire. The second part, “Volition, Action, and Causation,” contains four essays focusing on Berkeley’s volitionism, on his thesis that only the activities of minds are causally efficacious. “Vision and the Perceptual Objects,” the third part of the volume, deals with Berkeley’s theory of vision and his doctrine that all of the objects of perception depend on God’s will for their existence.

Following Snyderman and Rothman, we surveyed expert opinions on the current state of intelligence research. This report examines expert opinions on causes of international differences in student assessment and psychometric IQ test results. Experts were surveyed about the importance of culture, genes, education, wealth, health, geography, climate, politics, modernization, sampling error, test knowledge, discrimination, test bias, and migration. The importance of these factors was evaluated for diverse countries, regions, and groups including Finland, East Asia, sub-Saharan Africa, Southern Europe, the Arabian-Muslim (...) world, Latin America, Israel, Jews in the West, Roma, and Muslim immigrants. Education was rated by N = 71 experts as the most important cause of international ability differences. Genes were rated as the second most relevant factor but also had the highest variability in ratings. Culture, health, wealth, modernization, and politics were the next most important factors, whereas other factors such as geography, climate, test bias, and sampling error were less important. The paper concludes with a discussion of limitations of the survey. (shrink)

BOOK REVIEWS $0 5 David Berman. George Ber~ley: Idealism anti the Man. Oxford: Oxford University Press, 1994. Pp. xi + 230. Cloth, $42.00. Professor Berman's focus on Berkeley is more on "the Man" than on the metaphysics and this engaging study will therefore be of greater value to those with a historical, rather than a philosophical, interest in the good bishop. The book is aptly subtitled, particularly if we understand 'idealism' in its first, or Platonic sense , rather than just (...) in the peculiarly Berkeleyan metaphysical sense. The first three of its eight chapters deal with Berkeley's metaphysics, but the bulk of the book is concerned with extraphilosophical events in Berkeley's life, in particular with the two most significant ones: the abortive Bermuda Project and the messianic, indeed almost mystical, devotion to tar-water as a medical panacea. One of the great virtues of Berman's book is that it ties together the three periods of Berkeley's career--"each marked by an.. (shrink)

My purpose herein is to demonstrate that Berkeley's only use of the argument from perceptual relativity (APR), in both of his major works, is ad hominem, that he uses it to undermine what he calls materialism. Specifically, I show that Berkeley does not use APR to conclude that sensible qualities are mind-dependent; rather he uses APR only to conclude that they are not in material substances; and that his real argument for the former is a quite different one: the heat-pain (...) identification argument.
