In a thought experiment we want to test how the emergence of adult neural stem cells could constitute an example for a scientific revolution in the sense of Thomas Kuhn. In his major work, The structure of scientific revolutions, 3rd edn, University of Chicago Press, Chicago (Kuhn 1996), the philosopher of science, Thomas Kuhn, states that scientific progress is not a cumulative process, but new theories appear by a rather revolutionary sequence of events. Kuhn built his theory on landmark events (...) taken from chemistry and physics, lacking examples from biology. Beginning with Ramon y Cajal’s famous quote, no new neurons after birth , from the early years of the twentieth century, and Reynolds and Weiss’s conflicting finding in 1992 of adult neural stem cells giving rise to new neurons, we will test how the finding of neural stem cells in the adult brain matches with Kuhn’s theory. The pivotal problem of defining a paradigm will be our main focus, since the emergence of adult neural stem cells has been acclaimed by the scientific community as the rebuttal of Ramon y Cajal’s paradigm.

Within a state-space approach endowed with a generalized potential function, mental states can be systematically characterized by their stability against perturbations. This approach yields three major classes of states: (1) asymptotically stable categorial states, (2) marginally stable non-categorial states and (3) unstable acategorial states. The particularly interesting case of states giving rise to exceptional experiences will be elucidated in detail. Their proper classification will be related to Metzinger’s account of self-model and world-model, and empirical support for this classification will be (...) surveyed. Eventually, it will be outlined how Metzinger’s discussion of intentionality achieves pronounced significance within a dual-aspect framework of thinking. (shrink)

Following much work in linguistic theory, it is hypothesized that the language faculty has a modular structure and consists of two basic components, a lexicon of (structured) entries and a computational system of combinatorial operations to form larger linguistic expressions from lexical entries. This target article provides evidence for the dual nature of the language faculty by describing recent results of a multidisciplinary investigation of German inflection. We have examined: (1) its linguistic representation, focussing on noun plurals and verb inflection (...) (participles), (2) processes involved in the way adults produce and comprehend inflected words, (3) brain potentials generated during the processing of inflected words, and (4) the way children acquire and use inflection. It will be shown that the evidence from all these sources converges and supports the distinction between lexical entries and combinatorial operations. (shrink)

Der Prozess biologischer wie anthropologischer Evolution ist heute Gegenstand gesicherter Theorie. In dieser Arbeit werden notwendige und zureichende -philosophische- Voraussetzungen derselben untersucht. Dichotomien (Geist - Materie) wie Reduktionismen (z.B. neo-empiristischer Provenienz) werden uberwunden durch ein Erklarungsmodell, das genannte Einseitigkeiten vermittels einer -strukturologischen- Reflexion auf das -Geist- wie -Materie- Gemeinsame hintergreift. - In diesem Zusammenhang werden endlich die herkommlichen Probleme von -Immanenz- und -Transzendenz- des Menschen im Sinn einer vollig neuen Fragestellung transformiert.".

1,857 adults rated the grandparental solicitude they received in childhood. Through a simple model based on the evolutionary concepts of ontogenetically differentiated reproductive strategy and paternity confidence, an ordered discriminative pattern of grandparental caregiving was predicted and confirmed by solid main effects, based on 603 complete cases. The maternal grandmother was the most caring. Unlike prevalent gender stereotypes, she was followed by the maternal grandfather, the paternal grandmother, and the paternal grandfather. The preferential grandparental solicitude was not influenced by residential (...) distance, grandparent age, and availability of other grandparents. A predicted higher correlation for male than for female progenitors between solicitude and phenotypic resemblance could be confirmed. (shrink)

In diesem Buch wird zunachst eine Topik asthetischer Begriffe entwickelt, die dann an wesentlichen Knotenpunkten der Geschichte von Asthetik und Kunstphilosophie von Platon bis in die Gegenwart erprobt und auf sie angewandt wird. Systematische und geschichtlich konturierte Uberlegungen erganzen einander. Von besonderem Interesse ist dabei die Reflexion von Kunsterfahrung und Kunstwerken durch philosophisches Denken. Auf diese Weise zeigt sich das fruchtbare Spannungsverhaltnis zwischen Theorieformen und der Vielfalt asthetischer Erscheinungsformen. Dem Verhaltnis tradierter Asthetik und der nicht-schonen Kunste der Moderne gilt ein (...) besonderer Fokus. Das Augenmerk der Studie begrenzt sich freilich nicht auf hohe und autonome Kunst; vielmehr richtet es sich besonders auch auf die Architektur und Gebrauchskunst. Auch der Asthetik des Performativen und ihrer Rolle in der Kunst der Moderne gelten eingehende Analysen. (shrink)

Die politische Weltlage im fruhen 21. Jahrhundert ist global und zugleich von tiefen Differenzen und Bruchen bestimmt. Sie verlangt daher nach einer neuen politischen Philosophie, die aber zugleich groae Traditionen politischen Denkens aufnehmen und auf ihre aktuelle Bedeutung hin uberprufen muss. Auch die Folgelasten der Ideologien der Moderne sind noch einmal zu reflektieren, um aus ihnen fur veranderte Zeiten Lehren zu ziehen. Der hier vorgelegte Ansatz verbindet daher ideengeschichtliche Rekonstruktion mit der Entfaltung einer systematischen politischen Philosophie, die auch Faktoren berucksichtigt, (...) die zumeist unterbelichtet bleiben: Interkulturalitat, Sicherheitsarchitektur, das Verhaltnis von Politik und Religion, Politik und Moral sowie von Politik und Recht. Eine Schlusselbedeutung kommt dabei dem Verhaltnis von Freiheit und Sicherheit und der Frage zu, ob dieses uberhaupt in ein Gleichgewicht zu bringen ist. Der Autor verfolgt den Anspruch, Normativitat und Realismus gleichermaaen Rechnung zu tragen. (shrink)

Bedarf die in Okonomie und durch mediale Vernetzung geeinte Welt auch einer gemeinsamen Grundphilosophie? Die Schwierigkeiten, auf einen tragfahigen Konsens in strittigen Grundfragen zu kommen, deuten in diese Richtung. Doch wie konnte jene Grundphilosophie aussehen? Das Buch von Harald Seubert nimmt programmatisch die Stromungen und Tendenzen interkultureller Philosophie auf und vertieft sie auf die Grundlinien einer Weltphilosophie, die sich, keineswegs eklektizistisch, auf westliche und ostliche Uberlieferungsstrome berufen kann. Dabei kommen namhafte westliche und ostliche Stimmen zu Wort, von Platon uber (...) Cusanus und Hegel bis zu Whitehead und Sri Aurobindo. Reflektiert werden aber auch die verschiedenen Disziplinen philosophischen Denkens, von der Naturphilosophie uber die Politische Philosophie und die Frage eines gemeinsamen Wertekonsenses bis zu Ontologie und Gottesfrage.

This essay argues that Oscar Wilde noticeably contributed to the emerging discourse about world literature, even though his views in this regard have to be unearthed from the margins of his works, from his early and unpublished American lectures and ‘between the lines’ of his major critical essays. Wilde’s implicit ideas around world literature can be understood as being closely related to his broader endeavour of redirecting and revaluing the pejorative discourse around ‘decadence’ in art and literature. More specifically, the (...) arch-aesthete preferred to use the word ‘romance’ rather than ‘decadence’, signalling a sensitivity attuned to what he called the ‘love of things impossible’. This reconceptualization of the decadent outlook was to inspire a critical ideal of literature which relied on creatively activating the other as Other, culminating in a vision of intersubjective, transcultural and unlimited literary communication. Wilde’s thought can be more specifically understood as anticipating central tenets of Gayatri Chakravorty Spivak’s evocations of the planetary, thus preparing the way for an alterity-oriented understanding of literary cosmopolitanism.

Plato (ca. 427- ca. 347 BCE), the preeminent Greek philosopher, has been extensively studied. A major field of Plato's comprehensive work is his political philosophy, which is multifaceted and multidimensional. The discourse on gender issues forms an integral part of it. In this context, one is surprised to notice that Plato's elaborations have been interpreted in quite contrasting ways. In some feminist discussions of classical philosophy, Plato's intellectual enterprise is evaluated as reflecting Greek male chauvinism. Such identification carries all manner (...) of stereotyping, and this is neither enlightening nor helpful for an overall understanding of Plato's teachings and his world of ideas. In the scholarly literature, one can make the surprising discovery that Plato's contribution to the understanding of gender roles in society slips the attention of authors who specialize in this topic. Plato was neither feminist in the modern sense nor a sexist. Plato was not a liberal thinker, and he did not take the initiative to make a case for women's liberties. And yet, he elaborates amply on issues of what is subsumed under women's liberation in our time: What else would we call a philosopher who, under the conditions of Greek society in the classical age, advocated for the participation of women in sports competitions and approved of the access of women to public offices, even to political leadership? In this study, priority lies in reconstructing Plato's ideas on women's roles viewed against the zeitgeist of gender issues in Greek society of classical antiquity. The analysis shows that Plato's speculations about gender and gender issues in an ideal society were nothing short of revolutionary. Plato on Women is a major contribution to political philosophy and gender studies as well as an important book for collections of Plato's works and scholarly literature focusing on this philosopher.

Kant's contribution to modern Protestant theology is as unmistakable as it is controversial. The authors of this volume are investigating a new perspective on the work of theology and the effects of Kant's philosophy of religion concentrated on biblical hermeneutics and dogmatic theology.

This paper argues that the allure of conspiracy theories lies in their evolutionary origins, specifically in our capacity to communicate unrepresented threats. Drawing on threat-detection psychology and error management theory, it posits that these theories serve as adaptive responses to perceived threats and social coalition-building, rather than as flaws in reasoning.

Da die beiden Begriffe "Kultur" und "Staat" uber eine groae inhaltliche Breite verfugen, ist das Feld der Interpretationsmoglichkeiten auaerordentlich weit. Wichtiger als der quantitative Umfang der Begriffe aber ist selbstverstandlich deren qualitative Bedeutung: Sowohl vom Begriff der Kultur als auch vom Begriff des Staates lasst sich sagen, dass sie im eigentlichen Wortsinne fundamental sind. Sie legen das Fundament fur das Zusammenleben der Menschen - mit Kultur ist dabei die (oft unsichtbare und doch uberall wirksame) Totalitat menschlicher Hervorbringungen gemeint, mit Staat (...) die institutionelle Grundordnung einer Gemeinschaft, welche die wichtigsten Regeln der Herrschaft in einem bestimmten Territorium verbindlich festschreibt. Der Zusammenhang zwischen Kultur und Staat, genauer: Die Abhangigkeit des Staates von der Kultur, ist offensichtlich: Staaten sind immer auch Ausdruck kultureller Werte und Ideale. Ein besonderes Kulturverstandnis schlagt sich in aller Regel auch in einem besonderen Staatsverstandnis nieder; dabei erweisen sich die primar ideellen Werte einer Kultur haufig sogar als prioritar gegenuber ihrer materiellen Verwirklichung in Institutionen. In jedem Fall gilt, dass beide, Staat und Kultur, aufs Engste miteinander verzahnt und ineinander verwoben sind. Wie dies von groaen (Kultur-)Theoretikern des 20. Jahrhunderts gesehen worden ist, dokumentiert dieser Band. (shrink)

Das fur alle Weltkulturen pragende Verhaltnis von Religion und Vernunft wird in diesem Buch einzigartig umfassend und differenziert dargestellt. Die bedeutenden Knotenpunkte des Nachdenkens uber Religion gewinnen, von der griechischen Antike bis in die Gegenwart, plastisch Kontur und werden zugleich souveran auf das aktuelle interkulturelle Gesprach der Weltreligionen bezogen. Der Autor geht von dem Befund aus, dass Religion keineswegs eine vergangene, sondern eine hochst aktuelle Realitat des 21. Jahrhunderts ist. Religionen haben deshalb auch fur Politik, Recht und Rationalitat massgebliche Bedeutung. (...) Eingehend wird das Problem der Aufklarung und der Sakularisierung thematisiert. Religion ist, so zeigt das Buch in einer impliziten Hermeneutik, nur in einer Verflechtung von Beobachter- und Teilnehmerperspektive zu erfassen. Darin liegt die aktuelle Bedeutung der Religionsphilosophie, die Seubert wieder ins Zentrum der Philosophie und der Geisteswissenschaften insgesamt ruckt. (shrink)

Scepticism, a philosophical tradition that casts doubt on our ability to gain knowledge of the world and suggests suspending judgment in the face of uncertainty, has been influential since its beginnings in ancient Greece. Harald Thorsrud provides an engaging, rigorous introduction to the central themes, arguments, and general concerns of ancient Scepticism, from its beginnings with Pyrrho of Elis to the writings of Sextus Empiricus in the second century A.D. Thorsrud explores the differences among Sceptics and examines in particular (...) the separation of the Scepticism of Pyrrho from its later form—Academic Scepticism—the result of its ideas being introduced into Plato's Academy in the third century B.C. Steering an even course through the many differences of scholarly opinion surrounding Scepticism, the book also provides a balanced appraisal of the philosophy's enduring significance by showing why it remains so interesting and how ancient interpretations differ from modern ones. _Copub: Acumen Publishing Limited _.

A Companion to the Spanish Scholastics offers a much-needed survey of the entire field of early modern Spanish scholastic thought. The volume introduces main themes and contexts of scholastics inquiry (theology, philosophy, ethics, politics, economics, law, science and the senses) through close examination of a wide range of texts, debates, methods, and authors, as well as in-depth discussion of the relevant literature. Each chapter includes a useful bibliography and serves as point of departure for future research. The volume not only (...) draws the sum of existing research, but also challenges established notions and breaks new ground. (shrink)

Bioscientists generate far more data than their minds can handle, and this trend is likely to continue. With the aid of a small set of versatile tools for mathematical modeling and statistical assessment, bioscientists can explore their real-world systems without experiencing data overflow. This article outlines an approach for combining modern high-throughput, low-cost, but non-selective biospectroscopy measurements with soft, multivariate biochemometrics data modeling to overview complex systems, test hypotheses, and making new discoveries. From preliminary, broad hypotheses and goals, many relevant (...) samples are selected and measured with respect to many informative variables. The resulting tables represent a “cacophony” of data. From these, the most relevant and reliable “underlying harmonies and rhythms” are extracted and tested statistically, displayed for interpretation, and used for prediction. Outliers are detected automatically. Interesting subsets of samples can then be chosen for in-depth analyses in subsequent research cycles. This pragmatic, top-down approach takes advantage of developments in both “soft,” data-driven modeling and “hard,” knowledge-driven cultures. Data analytical examples show how information-rich biospectroscopy can be used for characterizing and quantifying known and unknown chemical constituents and physical phenomena in intact biosamples. This is based on a combination of deductive “hard” and inductive “soft” modeling. The examples represent NIR spectra of biochemical mixtures, FTIR spectra of a microbiological fermentation process, and FTIR analysis of fatty acids in milk for functional genomics. (shrink)

The following discussion aims to illuminate further the way in which morphologically complex words are represented in the mental lexicon. It is argued that the dual-mechanism model can accommodate the linguistic and psycholinguistic evidence currently available, not only on German inflection (as pointed out in the target article) but also on other languages (as presented in several commentaries). Associative single-mechanism models of inflection, on the other hand, provide only partial accounts.

It is widely accepted that consciousness or, more generally, mental activity is in some way correlated to the behavior of the material brain. Since quantum theory is the most fundamental theory of matter that is currently available, it is a legitimate question to ask whether quantum theory can help us to understand consciousness. Several approaches answering this question affirmatively, proposed in recent decades, will be surveyed. It will be pointed out that they make different epistemological assumptions, refer to different neurophysiological (...) levels of description, and use quantum theory in different ways. For each of the approaches discussed, problematic and promising features will be equally highlighted. (shrink)

We argue that the model developed in Epstein et al.'s target article does not explain differences between child first language (LI) acquisition and adult second language (L2) acquisition. We therefore sketch an alternative view, originally developed in Clahsen and Muysken (1989), in the light of new empirical findings and theoretical developments.
