Friedrich Schleiermacher (1768–1834) hat die Ethik als Theorie der Strukturen und Formen der geschichtlichen Welt konzipiert. Seine Entwürfe dieser „Wissenschaft von den Prinzipien der Geschichte“, die im Zusammenhang mit Vorlesungen ausgearbeitet und erst nach seinem Tod veröffentlicht worden sind, haben für seine Philosophie wie für seine Theologie grundlegende Bedeutung.

Albert Lewis's article analysing the influence of Friedrich Schleiermacher on Hermann Grassmann, stimulated many different studies on the founder of n-dimensional outer algebra.Following a brief outline of the various, sometimes diverging, analyses of Grassmann's creative thinking, new research is presented which confirms Lewis's original contribution and widens it considerably. It will be shown that:i. Grassmann, although a self-taught mathematician, was at the centre of a hitherto understated intellectual trend, which was defining for Germany. Initiated by Pestalozzi's concept of elementary (...) mathematical education and culminating in the modern mathematics of the late 19th Century, it was reflected in the contributions of Grassmann, Riemann, Jacobi and Eisenstein.ii. Hermann Grassmann, his father Justus, and his brother Robert were all demonstrably influenced by Schleiermacher's dialectic; however the two brothers responded to it in very different ways.iii. Whilst the more philosophical parts of Hermann's 1844 Extension Theory are characterised by the influence of Schleiermacher and also by the mathematical knowledge of his father, the entire development of this work is the unfolding of a single idea based on the father's interpretation of combinatorial multiplication as a ‘chemical conjunction‘, which was developed largely dialectically by Hermann.

About the relationship of the two traditions of Platonic interpretation the indirect and the direct traditions, the written dialogues and the unwritten doctrines.

Ever since the proposal of Giovanni Reale, it has been useful to distinguish three “paradigms,” or models of “normal science,” in Thomas Kuhn’s sense, in the history of Platonic scholarship, each of which are relatively distinct from the others in their historical succession: the Neoplatonic model which persisted into modern times; the “Romantic” model which replaced it and whose foundations were formulated around 1800 by Friedrich Schlegel and Friedrich Schleiermacher, and which was until recently the guiding model for (...) history, philology and philosophy; and lastly the model that takes both the literary and indirect Platonic traditions, integrates them, uses them to supplement one another, and so in part preserves and in part modifies the second model by a perspectival “paradigm shift”. The new research program justified itself in view of the surplus of anomalies left by the old program, which had to leave certain central portions of the tradition unexplained or else forcefully reinterpret them. Meanwhile, the new program promised to progressively work off the explanatory deficit. The new program was also able to emerge as an alternative because the explanatory abilities of the old program had visibly declined into a state of stagnation and exhaustion. That program had not achieved the hoped-for explanatory goals: neither the extraction of the philosophical content of Platonic dialogues by an analysis of form, nor the evaluation of the relative chronology of the dialogues for the inner development of their philosophical thought.

Social order and social change is based on social action. All sociological theories of action agree on this assumption. Beyond that insight action theories disagree on basic notions of how action can be explained, on basic principles clarifying the selection of action and on basic motivations of action as starting point to construct theories of social order and social change. Contemporary sociology accepts the multidimensionality of theoretical approaches. Open are questions of how action theories can be differentiated, related or combined (...) to offer analytical instruments for empirical research. The idea this essay brings forward is that the classical dualism between utilitarism (homo oeconomicus) and normativism (homo sociologicus) is transcended in support of action theories concentrating on the meaning of culture (cultural turn), communication (linguistic turn), and on creativity (dialogical turn). Integrated as a new typology these five action theories provide an analytical framework to research social order and social conflicts of modern societies. (shrink)

Was halt eine Gesellschaft im Innersten zusammen? Was macht das Wesen von Freundschaften aus? Wie kann man der Liebe Dauer verleihen? In drei Essays fasst Hans-Joachim Pieper aktuelle und traditionelle Antworten der Philosophie zusammen und zeigt, wie eng die Formen und Motive des Sozialen miteinander verstrickt sind. LIebe kann sich in Institutionen manifestieren. MItgefuhl und Nachstenliebe spielen bei allem Miteinander eine Rolle. FReundschaften werden in Gesprachen und Unternehmungen, in Netzwerken, Parteien und Freizeitvergnugungen gepflegt. IN lebenslangen Verbindungen gewinnt die (...) Freundschaft eine herausragende Gestalt. ZUgleich bildet sie auch einen wesentlichen Bestandteil der Liebe. Die Gemeinsamkeiten der hier besprochenen Formen des Miteinanders und ihre Vielfalt geben Grund zur Hoffnung, dass die Menschen letztlich mehr zum Frieden neigen als zum Krieg und dass die Rede von der Menschheit nicht nur Schonrederei ist.

Auf die metatheoretische Diskussion der deutschen Gegenwartspadagogik haben Kritische Theorie und Kritischer Rationalismus einen pragenden Einfluss. Die Untersuchung beleuchtet die Moglichkeiten und Grenzen ihrer Rationalitat anhand eines kritischen interparadigmatischen Vergleichs. Dieser ist thematisch konzentriert auf Probleme der erzieherischen Zielreflexion.".

Die Möglichkeitsspekulation des Duns Scotus (1266-1308) gehört zu den bemerkenswertesten metaphysischen Konstruktionen des späteren Mittelalters. Im vorliegenden Buch unternimmt der Verfasser den Versuch, anhand der systematischen Entfaltung der beiden Möglichkeitsstufen (logische und reale Möglichkeit) nachzuweisen, dass hier eine «Philosophie der Endlichkeit» vorliegt, die sich selbst transzendiert, gleichsam von selbst in Metaphysik übergehen muss. Das Ergebnis ist eine originelle und weit vorausweisende Begründung kontingenten, endlichen Seins.
