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

This paper addresses the question, which sex ratio will evolve in a population that is subject to mutation and drift. The problem is analyzed using a simulation model as well as analytical methods. A detailed simulation model for the evolution of a population's allele distribution shows that for the sex ratio game a wide spectrum of different population states may evolve from on the one hand a monomorphic state with one predominant allele and with all other alleles suppressed by the (...) forces of selection, to on the other hand a polymorphism determined by recurrent mutations. Which of these states will evolve depends on the population size, the mating system and the rate of mutations. For the sex ratio game the evolutionarily stable strategy (ESS), as defined by evolutionary game theory, can only predict the population sex ratio but not the underlying stable population state. A comparison of different approaches to the problem shows that false predictions of the stable population states might result from two simplifying assumptions that are fairly common in evolutionary biology:a) it is assumed that mutations are rare events and there is never more than one mutant gene present in a population at any one time; b) a deterministic relationship is assumed between the fitness assigned to an individual's strategy and the individual's contribution to the gene pool of future generations.

In hi s exegesis Calvin aimed at a living expression of the Scriptures in the confident expectation that God's Word in its unity would be given through them.

For an appropriate understanding of Leibniz's calculus the concept of differential is a crucial one. In Die Differentialrechnung nach Leibniz -eine Rekonstruktion (published in this journal in 2001) the calculus differentialis of Leibniz was analysed. In this paper we deal with the first systematic formulation of the calculus integralis, the Lectiones mathematicae de methodo integralium aliisque of Johann Bernoulli from 1691/92. It will be pointed out that Leibniz's theory is consistent and can be reconstructed as an empirical theory within the (...) structuralist metatheory. (shrink)

In the history of mathematics Leibniz as one of the scientists who developed the calculus of differentials has an outstanding position. However, it is difficult to reconstruct his theory in a consistent way. The main problem is the concept of differential. For an adequate understanding of this concept it is necessary to analyze how it is used. In this article we deal with the first systematic formulation of Leibniz' calculus, the Lectiones de calculo differentialium of Johann Bernoulli from 1691/92. It (...) will be proved that Leibniz's theory is consistent and can be reconstructed as an empirical theory - concerning physical curves - within the structuralist metatheory. The concept of differential is a theoretical one in respect to this theory. (shrink)

Im Wintersemester 1967/68 bin ich nach Göttingen gegangen, um dort ein Studium der Germanistik, Klassischen Philologie und Philosophie zu beginnen. Schon im zweiten Semester habe ich die Philosophie anstelle der Germanistik als Hauptfach genommen. Die Philosophie in Göttingen wurde damals von Günther Patzig und Erhard Scheibe vertreten, der eine die Kapazität der klassischen griechischen Philosophie in Deutschland, der andere – mit einem massiven Hintergrund in der Mathematik und Physik – in der Wissenschaftstheorie und Logik zu Hause.

After Second World War Hans Joachim Iwand reacts upon the experiences during the time of Nazi-Germany with a conception, which deals in a new way with the questions of political ethics. In this conception Iwand criticized the bipolar and traditional pattem of »State and Church« and explores »Society« as a selfcontained and autonomaus theme for political ethics. It is remarkable to see, how lwands approach to »theologia crucis« and the notions of the term »consciene« are now transformed in an pneumaticological (...) way, that opens the ethic for a conception of public responsibility.

With the late Author’s kind permission, the present text is published here in a somewhat abbreviated and modified translation that has been given appropriate subheadings and supplemented with an extensive bibliography. Its German original from 1996 has been translated into French and English. The purpose of the present translation is to make the Polish reader acquainted with the important and innovative account of Plato’s philosophy that has been put forward by the Tübingen School whose one of the most prominent co-founders (...) was Hans Joachim Krämer. While this text is devoted to Plato’s critique of writing, it also presents Plato’s agrapha dogmata as an important supplement to the written dialogues. A fuller overview of the major assumptions of this new interpretation is to be found in the recently published Gesammelte Ansätze zu Platon. (shrink)

In the near future three anniversaries are to be celebrated: Hans-Joachim Schoeps, German-Jewish scholar and full Professor of Religious and Intellectual History, would have been 100 years old in January 2009. Jointly together with Ernst Benz, full Professor of Theology at the University of Marburg, Hans-Joachim Schoeps launched the Journal of religious and intellectual history, which is now entering its 60th volume. Also, the Scientific Association for religious and intellectual history, which was as well founded by Hans-Joachim Schoeps, is going (...) to celebrate its 50th anniversary. The article depicts biographical data and scholarly highlights of Schoeps, and combines them with a view to the development of ZRGG and GGG. (shrink)

Die Erregung, mit der in den 1960er-Jahren der von Theodor Adorno und anderen so genannte „Positivismusstreit“ ausgetragen wurde, hat sich in den fast 50 Jahren, die vergangen sind, seit 1969 der Sammelband zur Debatte veröffentlicht wurde, weitgehend gelegt. Das macht es möglich, von der Parteinahme für die eine oder andere Seite Abstand zu nehmen und noch einmal präziser die Argumente von damals zu durchdenken. Es zeigt sich, dass in der Diskussion zwischen Karl Popper und Theodor Adorno in Tübingen 1961 die (...) Gemeinsamkeiten die Divergenzen bei weitem überwogen. Erst mit dem Eintritt on Jürgen Habermas und Hans Albert in die Debatte kam eine polemische Schärfe in die Diskussion, zum Teil durch die Etikettierung der Position Poppers als „Positivismus“ durch Habermas und dann auch Adorno. Zusätzlich wird hier versucht, die Debatte der 1960er-Jahre dadurch zu historisieren, dass sie in einen weiteren Zeitrahmen eingebettet wird, der einerseits die weit in die 1920er- und 1930er-Jahre reichende Vorgeschichte des Streits sowie andererseits die Folgen der Auseinandersetzung seit den späten 1960er-Jahren einbezieht.Die Darstellung beruht auf früheren Arbeiten des Verfassers. Zusätzlich werden einige neue Archivfunde präsentiert und inzwischen erschienene Autobiografien bzw. Biografien der Beteiligten des Positivismusstreits ausgewertet. Es bleibt zu hoffen, dass sich in Zukunft die bislang nicht zugänglichen Teile des Briefwechsels zwischen Adorno und Popper noch auffinden lassen. (shrink)
