Individual questions of the institutional reforms of the representative-democratic parliamentary system, such as issues of electoral law, party law, and parliamentary law, are frequently discussed. But all these reflections - and this is the principal thesis of this article - must eventually remain without success, if they do not address the preceding basic problem concerning the democratically indispensable conditions of the mental constitution of the active citizen, the „civis“. There, a key role, consciously experienced like a paradox, falls upon the (...) renunciation of the claim to absolute truth of one’s own political convictions with regard to equally „relative-absolute“ claims for validity of others. On this base the psychological presuppositions of a modern pluralistic democracy are discussed, which thereupon are to be institutionalized: e. g. the capacity to compromise, the obligation of state neutrality in religious matters, the renunciation of hate speech, the rejection of „denial of reality“, and of allegedly „finalizing“ ideologies of history.

Like Kant at his time, Jürgen Habermas wants to encourage the reader to use his „reasonable liberty“. There is no doubt, that the philosophical positions of Kant on the one hand and of Hegel on the other hand hold, until today, a key role in the development of the „discourse of modern age“. In order to oppose a short-circuited synthesis of both systems, which are obliged to the idea of liberty quite differently, this essay demonstrates the substantial differences regarding to (...) elementary concepts like peculiarity of the individual will, law and legislation, people and sovereignty of the people. That both philosophers differ in their interest of questioning becomes quite clear regarding to the citizen/state relation. While Hegel tries to describe the reality of the state as a „moral universe“ and therefore as „reality of reason“, Kant is interested in knowing about the potential state togetherness of individuals which have experienced in them the „radical evil“. The differences concerning the estimation of the „subjective“ individual will in its relationship to the „objective“ will of „generality“, concerning also the (Rousseauian) concept of contract and the citizens as „co-legislators“ are culminating in the relationship between „law“ and „morality“. Whereas Kant (wrongly) ignores ethos and history, Hegel is lacking the concept of „intersubjective communication“ (so Habermas states). From both insufficiencies conclusions are resulting which are important for coping with the actual difficulties with „inclusion“ and „integration“. (shrink)

During his whole scientific life Hermann Weyl was fascinated by the interrelation of physical and mathematical theories. From the mid 1920s onward he reflected also on the typical difference between the two epistemic fields and tried to identify it by comparing their respective automorphism structures. In a talk given at the end of the 1940s he gave the most detailed and coherent discussion of his thoughts on this topic. This paper presents his arguments in the talk and puts it in (...) the context of the later development of gauge theories. (shrink)

Ever since Parmenides, one of philosophy's riddles has been how we are able to direct our thoughts to non-being. Erhard uses the problem of non-existence as the starting point for an analysis of Husserl's phenomenology. He examines Husserl's interpretation of judgments about non-being as judgments made "under assumption" and his analysis of "free fantasy." Erhard thus demonstrates that Husserl is compatible with today's non-relational theories.

In this paper I argue that the almost forgotten early dissertation of the phenomenologist Hans Reiner Freiheit, Wollen und Aktivität. Phänomenologische Untersuchungen in Richtung auf das Problem der Willensfreiheit engages with what I call the unity problem of activity. This problem concerns the question whether there is a structure in virtue of which all instances of human activity—and not only “full-blown” intentional actions—can be unified. After a brief systematic elucidation of this problem, which is closely related to the contemporary “problem (...) of action,” I elaborate and critically discuss two relevant threads running through Reiner’s work. The first view concerns the alleged motivational asymmetry between activity and passivity according to which it is essential only for active experiences to be motivated by an underlying passivity. The second view focuses on Reiner’s phenomenology of the will, especially on his notions of “ego-centrality” and “inner will” the latter being introduced in analogy to Brentano’s notion of “inner consciousness.” These two notions are supposed to unify all manifestations of the human will, including “full-blown” intentional actions and non-intentional doings such as laughter. Reiner’s extension of will-based actions to non-intentional activity is one of the most remarkable aspects of his early work. Finally, I show that Reiner ultimately answers the unity problem in the negative because he ends up with the view that besides will-based agency he also acknowledges so-called “motor activity” which is not intrinsically related to the will. I close with a couple of tentative proposals how volitional and motor actions might be unified nonetheless. (shrink)

Biofilms can be viewed as tissue‐like structures in which microorganisms are organized in a spatial and functional sophisticated manner. Biofilm formation requires the orchestration of a highly integrated network of regulatory proteins to establish cell differentiation and production of a complex extracellular matrix. Here, we discuss the role of the essential Bacillus subtilis biofilm activator RemA. Despite intense research on biofilms, RemA is a largely underappreciated regulatory protein. RemA forms donut‐shaped octamers with the potential to assemble into dimeric superstructures. The (...) presumed DNA‐binding mode suggests that RemA organizes its target DNA into nucleosome‐like structures, which are the basis for its role as transcriptional activator. We discuss how RemA affects gene expression in the context of biofilm formation, and its regulatory interplay with established components of the biofilm regulatory network, such as SinR, SinI, SlrR, and SlrA. We emphasize the additional role of RemA played in nitrogen metabolism and osmotic‐stress adjustment. (shrink)

Inwiefern ist Metaphysik heutzutage noch relevant? Gibt es einen Sinn, in dem Metaphysik fur die Philosophie unverzichtbar ist? Was ist gute Metaphysik, und worin unterscheidet sie sich von schlechter Metaphysik? Was sind Chancen und Probleme genuin metaphysischen Denkens? Die Beitrage des Sammelbandes widmen sich diesen Fragen aus historischer und systematischer Perspektive.

Hermann Weyl was one of the early contributors to the mathematics of general relativity. This article argues that in 1929, for the formulation of a general relativistic framework of the Dirac equation, he both abolished and preserved in modified form the conceptual perspective that he had developed earlier in his “analysis of the problem of space.” The ideas of infinitesimal congruence from the early 1920s were aufgehoben in the general relativistic framework for the Dirac equation. He preserved the central idea (...) of gauge as a “purely infinitesimal” aspect of symmetries in a group extension schema. With respect to methodology, however, Weyl gave up his earlier preferences for relatively a-priori arguments and tried to incorporate as much empiricism as he could. This signified a clearly expressed empirical turn for him. Moreover, in this step he emphasized that the mathematical objects used for the representation of matter structures stood at the center of the construction, rather than interaction fields which, in the early 1920s, he had considered as more or less derivable from geometrico-philosophical considerations.

ERHARD SCHEIBE Kant's Apriorism and Some Modern Positions The terms a priori and its counterpart a posteriori are of medieval origin.1 In the fourteenth ...

Scheibe is one of the most important philosophers of science in Germany. He has written extensively on all the problems that confront the philosophy of physics: rationalism vs. empiricism; reductionism; the foundations of quantum mechanics; space-time, and much more. Since little of his work has been translated into English, he is not yet well known internationally. However, this collection of some 40 of his papers will remedy this unfortunate situation.

Dans un discours prononcé à Zurich vers la fin des années 1940, Hermann Weyl a examiné l'épistémologie dialectique de Ferdinand Gonseth et l'a considérée comme trop strictement limitée aux aspects de changement historique. Son expérience de la philosophie diaclectique post-kantienne, en particulier la dérivation du concept de l'espace et de la matière chez Johann Gottlieb Fichte, avait constitué une base dialectique solide pour ses propres études de 1918 en une géométrie purement infinitésimale et la théorie antérieure d'un champ de matière (...) géométriquement unifié (en prolongement du programme Mie-Hilbert). Bien que Weyl se fût alors éloigné des aspects spéculatifs de la philosophie de sa jeunesse et eût montré, en particulier, moins d'enthousiasme qu'auparavant pour Fichte, il nourrissait encore de nombreux doutes sur la base culturelle de la science mathématique moderne et sur son rôle dans la culture matérielle du modernisme de pointe. Pour Weyl, la « réflexion » philosophique était une nécessité culturelle ; il se tourna alors vers lexistentialisme de Karl Jaspers et de Martin Heidegger pour trouver des raisons plus profondes, dans un mouvement comparable à son orientation vers la philosophie de Fichte après la Première Guerre mondiale. Le débat de la fin des années 1940 peut être compris comme une sorte de supplément postérieur à la Seconde Guerre mondiale par rapport à ses commentaires plus connus sur les mathématiques et les sciences naturelles publiés au milieu des années 1920.

In this paper I offer a reconstruction of one of Husserl’s various anti-materialist arguments. Husserl hints at this argument in Ideas II & III where he exposes essential differences between mental and material reality (Realität). At its core, Husserl claims that mental entities by their very essence can never be in the same qualitative condition at different times. By sharp contrast, for purely material or physical entities such a cyclical development is not essentially excluded. Accordingly, I will speak of Husserl’s (...) argument from irreversibility. I argue that this argument is modal in nature, and that it can be used to make a case against materialism based on the necessary supervenience of the mental on the physical. My primary goal is to elucidate this argument, and to offer a logical reconstruction using basic modal logic and contemporary notions of supervenience. I conclude that Husserl’s argument is formally valid, and that it can even held to be sound, although the premise regarding the necessary irreversibility of the mental requires further clarification.
