In Homer’s account of the adventurous journey of Odysseus, the song of the sirens was so appealing and tempting that it lured sailors to their deaths. Warned by the goddess Kirke, Odysseus overcame the trap by plugging his crew’s ears with wax. An archaeo-acoustical research expedition undertaken by members of Humboldt University Berlin made sound propagation experiments at the supposedly historical scene at the Galli Islands where it’s said that the sirens originally sung. At the site we broadcasted both synthetic (...) signals and natural voices via loudspeakers in the direction Odysseus most probably should have approached the Siren’s island. Subjective listening as well as objective acoustic analysis of the recorded signals revealed evidence for a combination of site-specific acoustic effects, which may explain the nature and origin of the song of the sirens in Homer. The local arrangement of the three islands deforms the acoustic signals by amplification and by changes in timbre. Two female singers from the Berlin State Opera were asked to sing differently pitched musical intervals to be tested in the Li Galli environment. The experiment evinced that the first overtones would be merged by the echo of the rocks; yet when singing pure thirds and less consonant intervals, which yield higher orders in the overtone series, the voices appear recognisable as being two. As a result, and particularly because Homer stresses the number of exactly two sirens several times, the evidence of our research supports the musicological theory for a rather early existence of enharmonic tunings and most prominently a two-part polyphonic singing of Greek songs. Given that the rocky formation of the Galli Islands most likely didn’t change during the geological tick of just 2,700 years, we conclude that there has been a real acoustic basis for the myth reported by Homer and that a “song of the Sirens”, most probably based on natural voices, was transformed by the particular acoustic conditions of the landscape in such a way that signals were amplified and sent out in one concrete direction. Based on these results, we continue to discuss further leading acoustic theories that offer new insights into the mythology and which were essential to motivate our expedition in the first place. After all, the question remains open what kind of beings the first emitters of the song might have been. (shrink)

This text explores how we understand living and other complex systems. The conventional basis of understanding rests on abstract general theories, but this book proposes conceptual continuity as a new means of comparing systems of divergent complexity and resolving problems in complex systems.

Excerpt from Fichte Die geistige Nahrung des Elternhauses bestand in einer innigen und strengen Religiosität. Der Trieb, der in dem Kinde hier zuerst geweckt wurde, hat Fichte, wie er selbst betont, zeitlebens tief in allem Sein und Tun bestimmt. Von seiner ersten Schrift an bis zur letzten sind es religiose Fragen und Erlebnisse gewesen, die sein Denken zu den letzten Wurzeln seiner Überzeugung fuhrten.

Zentrale Denkfiguren der von Wolfgang Klafki begründeten kritisch-konstruktiven Erziehungswissenschaft werden in diesem Buch aufgegriffen und in ihrem Innovationswert für die wissenschaftliche Pädagogik reflektiert. Namhafte Autorinnen und Autoren unterschiedlicher Subdisziplinen und Generationen vertiefen Klafkis Ansatz theoretisch wie methodisch und öffnen Problemstellungen, die bisher nicht bearbeitet worden sind.

In den 'Orolegomena' wird vom Herausgeber der Durchbruch zu einer konsequenten Konzeption der interkulturellen Philosophie dargestellt. D. Tiemersma untersucht, wie Merleau-Ponty durch eine Auseinandersetzung mit kulturanthropologischen Forschungen zu einer Erweiterung des Bewußtseinsbegriffs und der Rationalitätskonzeption gelangt. Die Ansprüche einer interkulturellen Philosophie werden von J. Hoogland von einer Habermas'schen Position aus kritisch überprüft. A.W. Prins interpretiert Heideggers 'Angang der interkulturellen Auseinandersetzung' trotz anders lautenden Äußerungen dieses Autors als einen wichtigen Beitrag zur interkulturellen Philosophie. Für einen Aufweis der inneren Affinität zwischen japanischem (...) Denken und einigen neonietzscheanischen Philosophen bezieht sich H. Oosterling auf Bataille, Barthes, Foucault, Lyotard und Derrida. Aus feministischer Perspektive wendet sich J. van den Oord der Frage der Universalität der Menschenrechte zu. In der Absicht, den Universalitätsanspruch der westlichen Demokratieform zu kritisieren, konfrontiert F. Uyanne afrikanische und westliche Demokratie-Konzeptionen. C. Jacobs beschreibt den interkulturellen Dialog, der in einigen wichtigen Kunstausstellungen in New York und Paris stattgefunden hat. Nachdem E. de Schipper tiefgehende Zweifel am hier beschrittenen Weg zur interkulturellen Philosophie ausgesprochen hat, werden zum Schluß in einer 'Replik' der Herausgebers noch einmal einige Ausgangspunkte des Projekts klargestellt.

The disease status of mental disorders has been hotly debated and is still highly relevant for ethical and economic considerations regarding the human rights of psychiatric patients. Here we critically discuss traditional evolutionary and degenerative concepts of mental disorders and propose instead the differentiation between independent dimensions of mental health resources on the one hand and mental disorders on the other. We suggest that impairments of a minimal set of mental functions can serve as indicators of exogenous and endogenous psychoses, (...) while other mental disorders cannot be diagnosed without a reference to setting and culture.

Ante la fragmentariedad de las ciencias particulares desarrolladas por el hombre en vísperas del siglo XXI, la obra Cosmos de Humboldt tiene dos puntos interesantes: (a) la sinopsis de los variados y nuevos conocimientos de entonces, y (b) la intención de definir el lugar del hombre en el Cosmos. Una relectura de Humboldt se hace necesaria para conocer su actitud frente a la dispersión del saber, la cual evitaría tener una visión de conjunto del sentido del todo. La tesis de (...) la autora en la primera parte es que dicha concepción se inscribe en el paradigma científico elaborado en la tradición del llamado neovitalismo. Con base en lo anterior, la segunda parte se centra en la relación entre naturaleza y espíritu. (shrink)
