This paper summarizes (in German) recent tendencies in the philosophy of the life sciences.

Three-dimensional material models of molecules were used throughout the 19th century, either functioning as a mere representation or opening new epistemic horizons. In this paper, two case studies are examined: the 1875 models of van ‘t Hoff and the 1890 models of Sachse. What is unique in these two case studies is that both models were not only folded, but were also conceptualized mathematically. When viewed in light of the chemical research of that period not only were both of (...) these aspects, considered in their singularity, exceptional, but also taken together may be thought of as a subversion of the way molecules were chemically investigated in the 19th century. Concentrating on this unique shared characteristic in the models of van ‘t Hoff and the models of Sachse, this paper deals with the shifts and displacements between their operational methods and existence: between their technical and epistemological aspects and the fact that they were folded, which was forgotten or simply ignored in the subsequent development of chemistry.

This is a study of Roman adaptations of Stoic doctrine that seeks to portray a model of the self functioning as a mediator between philosophical and traditional values (1). The author’s aim is ‘to let the Roman Stoics’ self arise out of a comprehensive analysis of their extant philosophical work and to conduct that analysis from the vantage point of the specific question of social embeddedness. Such an approach yields a Stoic self that is constituted by the encounter between challenges (...) and normative expectations’ (2). Overall, this aim is met. The Roman Stoics referred to are Seneca, Musonius Rufus, Epictetus, Marcus Aurelius, and to a lesser extent Hierocles, who ‘all had to come to terms with the sociopolitical challenges of imperial Rome’ (3). The tame thesis advanced is that the doctrine of these Roman Stoics ‘shows a distinctive pattern of emphasizing social responsibility’ (3). This social responsibility includes commitments to the political community, marriage, and parenthood. (shrink)
