Rudolf Carnap gilt unbestritten als einer der eminentesten Vertreter des logischen Empirismus. Im Band 2 der Reihe "Texte zur Wissenschaftlichen Weltauffassung" werden alle wesentlichen Aspekte seiner Philosophie zusammenhAngend dargestellt und kritisch analysiert. Lothar Krauth beurteilt dabei Carnaps Bedeutung vor einem breiten, philosophiehistorischen Hintergrund. Nicht nur sein EinfluA und seine Vordenkerrolle im Wiener Kreis werden diskutiert, sondern auch die mehrfache Wandlung in Carnaps Denken. So erklArt sich manche allzu groAe Vereinfachung, mancher Radikalismus als erster Ansatz, der spAter A1/4berarbeitet, zu einem (...) tragfAhigen Bestandteil kommender analytischer Sprachtheorie ausgebaut wurde.

Alongside the 'critical theory' of the Frankfurt School, West Germany was also home to another influential Marxist current known as the Marburg School. In this volume, Marburg disciple Lothar Peter traces the school's history and situates it in the political discourse and developments of its time. The renowned political scientist Wolfgang Abendroth plays a large role, but unlike most histories of the Marburg School Peter also takes the sociologists Werner Hofmann and Heinz Maus into account as well as their (...) many students and successors. They were united by the conviction that teaching and scholarship must necessarily be tied to the practical goal of transforming society - an approach that met with considerable opposition in the harshly anti-Communist atmosphere of the period.

Substantial evidence indicates that cognitive training can be efficacious for older adults, but findings regarding training-related brain plasticity have been mixed and vary depending on the imaging modality. Recent years have seen a growth in recognition of the importance of large-scale brain networks on cognition. In particular, task-induced deactivation within the default mode network is thought to facilitate externally directed cognition, while aging-related decrements in this neural process are related to reduced cognitive performance. It is not yet clear whether task-induced (...) deactivation within the DMN can be enhanced by cognitive training in the elderly. We previously reported durable cognitive improvements in a sample of healthy older adults who completed 6 weeks of process-based object-location memory training compared to an active control training group. The primary aim of the current study is to evaluate whether these cognitive gains are accompanied by training-related changes in task-related DMN deactivation. Given the evidence for heterogeneity of the DMN, we examine task-related activation/deactivation within two separate DMN branches, a ventral branch related to episodic memory and a dorsal branch more closely resembling the canonical DMN. Participants underwent functional magnetic resonance imaging while performing an untrained object-location memory task at four time points before, during, and after the training period. Task-induced activation values were extracted for the ventral and dorsal DMN branches at each time point. Relative to visual fixation baseline: the dorsal DMN was deactivated during the scanner task, while the ventral DMN was activated; the object-location memory training group exhibited an increase in dorsal DMN deactivation relative to the active control group over the course of training and follow-up; changes in dorsal DMN deactivation did not correlate with task improvement. These results indicate a training-related enhancement of task-induced deactivation of the dorsal DMN, although the specificity of this improvement to the cognitive task performed in the scanner is not clear.

The major theoretical framework relative to the perception of illusory figures is reviewed and discussed in the attempt to provide a unifying explanatory account for these phenomena.

Le portrait politique de Constant est divisé en quatre parties.

The positive revaluation of aesthesis and the emergence of aesthetics in the 18th century - from Bodmer and Breitinger to Baumgarten, Meier and ultimately Herder - established an aesthetic discourse centred on the sensual component of art and literature. In literature, this component is to be found in its visual imagery, its rhythms and also in its appreciation as a meaningful structure. The volume contains studies on Gryphius, Klopstock, Lessing, Wieland, Herder and Schiller. It systematizes the insights gained from these (...) studies to demonstrate how, in the 17th and 18th centuries, aesthetic experience was enriched by a theoretical concern for its sensual aspects and conceptualized in a manner that is of essential importance for approaches to the interpretation of art and for hermeneutics.

"Die Kritik ist nicht die Wissenschaft." Zu diesem Ergebnis führt eine Besinnung auf den Begriff der Objektivität in der kunstwissenschaftlichen Forschung. Die aktuelle Situation, die durch wissenschaftstheoretische und methodologische Überlegungen bestimmt ist, verlangt neue Zielsetzungen und Aufgaben. Das zentrale Problem - die Begründung der Ästhetik als selbständige, moderne Wissenschaft - steht und fällt mit der Frage, ob die Kunst Gegenstand einer generellen, empirisch prüfbaren Theorie sein kann. Der zeitgenössische Strukturalismus glaubt diese Frage positiv beantworten zu können. Er versucht, die ästhetischen (...) Gebilde nicht nur als registrierbare Einzelfälle zu erklären und zu bewerten, sondern auf allgemeinere Gesetzmäßigkeiten zurückzuführen. (shrink)
