This paper investigates Hermann Weyl’s reception of philosophical concepts stemming from the German Idealist Johann Gottlieb Fichte. In particular, Weyl’s ‘agens theory’ of matter, which he held around 1925, will be looked at. In the extant literature, the—admittedly also important—influence of Husserl on Weyl has mainly been addressed. Thus, apart from investigating some detailed Fichtean inheritances in Weyl’s concepts of causality, chance and continuity, the general difference which Weyl saw between the philosophies of Fichte and Husserl will also be discussed. (...) For Weyl this is above all a difference between an active constructivism and a rather passive phenomenological seeing. Further, the paper shows in some detail the way Weyl was drawn into a certain reading of Fichte by his Zurich colleague, the philosopher Fritz Medicus. The methodological frame of the paper is that of Konstellationsforschung, a historical and systematic approach which proves to be particularly fruitful when investigating a German Idealist context and which allows special attention to be given to the acting subjects within the constellation under investigation. Conversely, Weyl’s agens theory suggests amendments to this methodology.Keywords: Hermann Weyl; Fritz Medicus; Johann Gottlieb Fichte; Theory of matter; Activity vs. passivity; Konstellationsforschung.

Leibniz, Husserl and the Brain is about the structural relations between phenomenological and neurophysiological aspects of perception, consciousness and time. Its focus lies with auditory perception, since nearly all perceived qualities in hearing - such as pitch, rhythm and the localization or origin of a sound - are most intimately related to temporal patterns and regularities. Here striking analogies are shown between the structural features of perceptual states, as dealt with in philosophical phenomenology, and of their physical counterparts, as dealt (...) with in neurophysiology. Accordingly, the comprehensive and consolidating references to the work of Leibniz and Husserl are not for philological reasons, but, rather, to work towards philosophical orientation in a conceptual maze. They allow for a fresh view on several issues in contemporary philosophy of mind and also in psychophysics - in particular, on the transition from unconscious to conscious states and on the constitution of time consciousness.

Obwohl es "die Zeit" nicht gibt, ordnet sich doch alles, was wir erleben, zeitlich. Auch die großen Schlagworte unserer Tage betreffen allesamt von zeitlichen Herausforderungen: Nachhaltigkeit, Resilienz, Transformation, Zeitenwende. Dieses Buch handelt davon, was Zeitliches ausmacht, warum sich die Wirklichkeit zeitlich ordnet und was das mit der wechselseitigen Taktung von Ereignissen und Autonomieerfahrungen zu tun hat. Es werden Missverständnisse aufgelöst, indem aufgezeigt wird, inwiefern es "die Zeit" nicht gibt, es oftmals sogar leidvolle bis hin zu pathologischen Konsequenzen mit sich bringt, (...) wenn Zeit als Gegenstand oder Ressource betrachtet wird. Es ist ein Buch über den Vergleich von Abläufen und darüber, was es bedeutet, wenn Ereignisse miteinander im Takt sind, und wie sie durch Wiederholung und Variation Bedeutung gewinnen und damit "intakt" wirken. Musik und vor allem das Hören dienen als Modelle, um diese allgemeinen zeitlichen Struktureigenschaften der Wirklichkeit begrifflich anklingen zu lassen. Darüber hinaus regen Hyperlinks zu konkreten Hörbeispielen dazu an, sich direkt auch auf besondere Erfahrungen von Zeit einzulassen. - Ein Buch für all diejenigen, die Grundlegendes über Zeit nicht nur lesen wollen, sondern sich im Idealfall auch für einen taktvollen Umgang mit Zeit motivieren lassen möchten.

Vers 1918 Hermann Weyl abandonnait le logicisme et donc la tentative de réduire les mathématiques à la logique et la théorie des ensembles. Au niveau philosophique, ses points de référence furent ensuite Husserl et Fichte. Dans les années 1920 il distingua leurs positions, entre une direction intuitionniste-phénoménologique d’un côté, et formaliste-constructiviste de l’autre. Peu après Weyl, Oskar Becker adopta une distinction similaire. Mais à la différence du phénoménologue Becker, Weyl considérait l’approche active du constructivisme de Fichte comme supérieure à la (...) vision d’essences passive de Husserl. Dans cet essai, je montre ce développement dans la pensée de Weyl. Bien que certains points dans sa réception de Husserl et Fichte ne soient pas soutenables, je vais argumenter en faveur de la distinction fondamentale mentionnée ci-dessus. (shrink)

Well-being depends not only on what happens but also on when it happens. There are temporal aspects of well-being, and to a large extent those aspects are about relative timing—about being “in-tact.” On the one hand, there is a perspectival aspect about being in-tact with one’s past, present, and future or, in a less involved sense, with one’s life as a whole. On the other hand, there is a synchronization aspect of being in-tact; and this aspect occurs on different levels: (...) It might be about the alignment between different temporal domains—such as time as individually perceived and physical or intersubjective time. Or it might be about a single domain, especially the inner dynamics of individual time. The danger of not experiencing and acknowledging the relational character of these different timings likely leads to a substantial loss in the variety of human experience. Important aspects of subjective and intersubjective experience might fade away. The present paper discusses these aspects of well-being along the lines of distinctions and concepts prominently used in the metaphysics and the phenomenology of time. Thus, the paper also aims to complement the existing literature by bringing together important strands of current philosophical research. (shrink)

This article investigates an intertwined systematic and historical view on theories of matter. It follows an approach brought forward by Hermann Weyl around 1925, applies it to recent theories of matter in physics (including geometrodynamics and quantum gravity), and embeds it into a more general philosophical framework. First, I shall discuss the physical and philosophical problems of a unified field theory on the basis of Weyl's own abandonment of his 1918 ‘pure field theory’ in favour of an ‘agent theory’ of (...) matter. The difference between agent and field theories of matter is then used to establish a sort of dialectic meta-view. With reference to Weyl this view can be understood as being a particular Fichtean transcendental idealist approach which attempts to combine the strengths of the Husserlian phenomenology and Cassirer's neo-Kantianism.

Nach Leibniz sind es die Summe und das Zusammenspiel der, wie er sie nennt, perceptions insensibles (nicht-wahrnehmbare Perzeptionen), die die (wahrnehmbaren) Perzeptionen begründen. Nicht-wahrnehmbare Perzeptionen bilden für ihn eine Voraussetzung für bewusste Zustände und sind konstitutiv für menschliche Individuen. Mit Blick auf die gegenwärtige Neurowissenschaft argumentieren wir dafür, dass neuronale Hirnaktivitäten als die physikalischen Analoga im Sinne Leibnizens solcher nicht-wahrnehmbaren Perzeptionen interpretiert werden können. Ergebnisse neurophysiologischer Forschung, denen zufolge bestimmte Hirnaktivitäten bewussten (wiederabrufbaren) Zuständen zeitlich vorausgehen, wären dementsprechend klarerweise zu erwarten. (...) Aus diesen und anderen Gründen halten wir den Leibniz'schen Ansatz für eine nützliche und wertvolle Grundlage, um neurophysiologische Ergebnisse in einem Rahmen diskutieren und beurteilen zu können, der über den rein innerphysiologischen hinausgeht.

The aim of this paper is to sketch an approach for integrating the historiography of the sciences and of philosophy. More precisely, the paper suggests a method for investigating interactions within transdisciplinary constellations of researchers working in philosophy and in the exact sciences. I start off by introducing specific notions of analogy, variation, and conceptual space which provide the main ingredients of this method. The notion of a conceptual space, as well as other characteristics of the present approach, are adaptations (...) from so-called constellation research. Originally, constellation research was developed for the historiography of philosophy – especially in the context of the origins of German idealism. However, as I will argue in the second half of the paper, it is adaptable to the historiography of science, especially of the exact sciences. To support this claim and to illustrate the integrative power of the present approach, I will compare the notions of a constellation and a conceptual space with Ludwik Fleck’s notions of a »thought collective« and a »style of thought«, critically evaluate the distinction between contexts of discovery and of justification in a historiographical context, and relate the notions of analogy and variation, as introduced in the first part of the paper, to current debates about what is sometimes called »invariantism« in the philosophy of science.

Holography is a fruitful concept in modern physics. However, there is no generally accepted definition of the term, and its significance, especially as a guiding principle in quantum gravity, is rather uncertain. The present paper critically evaluates variants of the holographic principle from two perspectives: their relevance in contemporary approaches to quantum gravity and in closely related areas; their historical forerunners in the early twentieth century and the role played by past and present concepts of holography in attempts to unify (...) physics. By combining these two perspectives a certain depth of focus is gained which allows us to draw some tentative conclusions about what might be reasonable aspirations and prospects for holography in quantum gravity. By the same token, we will have a brief and critical look at wider philosophical interpretations of the term. (shrink)

This paper shows how different axiomatic and constructive approaches within quantum field theory can be understood in terms of the so-called ,picture theory' of Heinrich Hertz. Each approach will count as a different picture due to the different status of the various concepts (symbols) they are employing, like observables, gauge invariance, confinement or the space-time continuum. An important difference with the original Hertzian approach is the fact that the different approaches in quantum field theory have partially overlapping, partially supplementing domains (...) of application. This also marks some of the parallels and differences with contemporary debates on structural realism and model-theoretic approaches in the philosophy of physics. The objection that the talk about different pictures just relies on the fact that quantum field theory is unfinished will be countered. Finally, the Hertzian approach will be briefly elaborated and embedded into its philosophical successor projects of Cassirer and Goodman. German Dieser Aufsatz zeigt, wie verschiedene axiomatische und konstruktive Ansätze in der Quantenfeldtheorie mit Hilfe der sogenannten ,,Bildtheorie“ von Heinrich Hertz verstanden werden können. Aufgrund der unterschiedlichen Stellungen der verschiedenen Konzepte (Symbole), die diese Ansätze benutzen - wie etwa Observable, Eichinvarianz, Confinement oder Raum-Zeit-Kontinuum - wird jeder als ein eigenes Bild zu betrachten sein. Ein wichtiger Unterschied zu Hertz' ursprünglicher Fassung der Bildtheorie sind dabei die unterschiedlichen Anwendungsbereiche der Ansätze in der Quantenfeldtheorie. Diese überschneiden sich zum Teil, zum Teil ergänzen sie einander. Dadurch ergeben sich für die bildtheoretische Interpretation wichtige Parallelen und Unterschiede zu anderen Positionen in der Philosophie der Physik, insbesondere zum Strukturrealismus und zur Modell-Theorie. Neben diesen diskutiere ich den Einwand, dass die Redeweise von verschiedenen Bildern in der Quantenfeldtheorie nur deshalb möglich sei, weil die Theorie noch nicht abgeschlossen ist. Schließlich erweitere ich die Hertzsche Bildtheorie und setze sie dabei in Beziehung zu ihren philosophischen Nachfolgeprojekten bei Cassirer und Goodman. (shrink)

Upon doing something generous for someone with whom you are close, some kind of reciprocity may be appropriate. But it often seems wrong to actually request reciprocity. This chapter explores the wrongness in making these requests, and why they can nevertheless appear appropriate. After considering several explanations for the wrongness at issue (involving, e.g. distinguishing oughts from obligation, the suberogatory, imperfect duties, and gift-giving norms), a novel proposal is advanced. The requests are disrespectful; they express that their agent insufficiently trusts (...) the hearer to recognize their own reasons to reciprocate, and the close relationship between them morally requires this kind of trust. This proposal is articulated and situated in the recent discussion of the normativity of requests. The chapter concludes by explaining how these requests may appear appropriate. Agents in these relationships often have standing to make requests, though the standing is lacking in these particular cases. (shrink)

Examining relativistic quantum field theory we claim that its description of subnuclear phenomena can be understood most adequately from a semiotic point of view. The paper starts off with a concise and non-technical outline of the firmly based aspects of relativistic quantum field theories. The particular methods, by which these different aspects have to be accessed, can be described as distinct facets of quantum field theory. They differ with respect to the relation between quantum fields and associated particles, and, as (...) we shall argue, should be interpreted as complementary (semiotic) codes. Viewing physical theories as symbolic constructions already came to the fore in the middle of the nineteenth century with the emancipation of the classical theory of the electromagnetic field from mechanics; most notably, as we will point out, with the work of Helmholtz, Hertz, Poincaré, and later on Weyl. Since the epistemological questions posed there are heightened with regard to quantum field theory, we considerably widen their approach and relate it to recent discussions in the philosophy of science, like structural realism and quasi-autonomous domains.

Deleuze’ün Spinozacı yaşam tahayyülünde ‘ne yapmalıyız?’ sorusuna normatif, ahlaki ya da siyasi bir yanıt bulamıyoruz ama varoluşu düşünmenin içkin bir olanağını keşfediyoruz. Düşünmeye 'dışarıdan' yani dünyadan başlamak insani (kurgusal) bir dünyaya değil, içinde yaşadığımız gerçek dünyaya inanmak demektir. İçkinliğin politik anlamı düşünceyi dünyaya getirmektir.
