The contribution focuses on Kant's distinction between right and ethics. According to Kant, ethical as well as juridical laws are laws of freedom. As such they can be recognized by rational beings as unconditionally binding. The decisive difference between right and ethics consists in the way that obligations are required in their respective realms of legislation. While ethical legislation cannot be external and ethics is also concerned with inner motivations, juridical duties do not command dispositions but specific actions.

Die Frage, wie das, was die Vernunft einsieht, dazu motivieren kann, dies auch zu tun, gehört zu den Grundfragen von Kants praktischer Philosophie. Die vorliegende Untersuchung erschließt Kants Antwort auf das Problem der moralischen Motivation innerhalb seiner Handlungstheorie und Moralphilosophie. Neben einer philosophiehistorischen und systematischen Einordnung liefert sie eine umfassende textnahe Analyse der kantischen Argumente, die auch werkgeschichtliche Aspekte berücksichtigt. Auf diese Weise entsteht ein reichhaltiges Bild der kantischen Theorie moralischer Motivation, die in Kants Konzept der Moralbegründung nicht nur verwurzelt (...) ist, sondern dieses auch unterstützt. So ist die Achtung vor dem Gesetz als Modus zu verstehen, in dem sich der Mensch die praktische Norm zu eigen macht. Moralische Gründe erweisen sich nach der hier vorgeschlagenen Interpretation als unbedingte, universal gültige Regeln, deren praktische Bedeutung als subjektive Handlungsgrundsätze und Motive erst durch Kants Theorie der moralisch-rationalen Sensibilität verständlich wird. Kants Ansatz ist damit nicht nur werkintern von Interesse, sondern liefert darüber hinaus einen inspirierenden Beitrag zu einer modernen Theorie praktischer Normativität. (shrink)

The view that morality consists of laws has a rich, particularly religious, tradition. In current debates on ethics, however, it is anything but philosophical commonsense. Not least due to the return to the advantages of virtue ethics, principle-oriented ethics such as the moral law approach have lost popularity. Despite this, the advantages of law-based ethics can also be defended; one paradigm here is still Immanuel Kant’s attempt to ground the objectivity of morality on the concept of a moral law. Accordingly, (...) the aim of this text is to explore the systematic potential of ethics based on the concept of law. For this purpose, I will examine the historical roots of a connection between the concept of morality and that of law and then focus on Kant’s approach to morality. Finally, I will outline the advantages of his conception of morality as autonomy over alternative models of justification of morality. (shrink)

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.
