The minimum-uncertainty states for systems with many degrees of freedom are investigated. The limiting situation, relevant to the electromagnetic field, is discussed and it is pointed out that the states that minimize Δp Δq do not tend to the coherent states. These latter, including the vacuum state, are minimum-uncertainty states for the transverse electric and magnetic fields. In an appendix a direct method to obtain the wave functional for the vacuum is presented.

»Mit Heideggers Eintreffen in Marburg begann … für das philosophische Denken eine neue Epoche.« – So erinnert sich Hans-Georg Gadamer an Heideggers Marburger Zeit, und nicht nur Heideggers eigenes Schaffen, auch die anhaltende Wirkung von Sein und Zeit und den anderen in Marburg verfassten Schriften und Vorlesungen, geben diesem Diktum recht. Seit diese Texte in der Gesamtausgabe vorliegen, wird immer deutlicher, wie sich Heidegger in Marburg philosophisch entwickelt hat, welche Ideen, Lektüren und Begegnungen diese Zeit prägten und (...) welche Wege Heideggers Denken in Marburg nahm. Als Ergebnis der »Übergangsarbeit« der Marburger Zeit hat Heidegger mit Sein und Zeit einen Text geschaffen, der zur Mitte seines Denkens werden sollte, und dies auch und gerade deshalb, weil dieses Werk Heideggers unvollendet geblieben ist. In einer Anmerkung zur letzten Seite heißt es in diesem Sinne, das Buch stelle einen Weg des Denkens da, aber »nicht ›den‹ einzigen«. Dass Sein und Zeit das in der Einleitung gesteckte Ziel nicht erreicht und Fragment geblieben ist, ist nur ein Anzeichen für die Komplexität, die wesentliche Schwierigkeit und innere Spannung der Themen, Argumente und Konstellationen, mit denen Heidegger sich in Marburg beschäftigt hat. ...

The paper focuses on the problem of constitution of our cognitive experience. Two approaches to this problem proposed by Cassirer and McDowell are central for the analysis. Both authors use Kant’s theory of cognition as a foundation for their own conceptions und they develop their independent interpretations of it according to the traditions they belong to. Although McDowell’s interpretation emerged within analytical philosophy, we can see similarity with Cassirer’s theory. Comparative studies of these theories will point out the convergences and (...) divergences between them. (shrink)

The article reconstructs some of the basic decisions underlying Hermann Cohen′s theoretical philosophy by drawing a line to some claims of Winfrid Sellars′ and to one aspect of Robert Brandom′s philosophy. The first part is concerned with a comparison of the main theses of Cohen′s book Kants Theorie der Erfahrung and Sellars′ early essay entitled “Some remarks on Kant′s Theory of Experience,” both authors reading the Critique of Pure Reason as the discovery of a new, holistic concept of experience. The (...) second part discusses some of the parallels between Cohen′s and Sellars′ respective critique of the myth of the given, and it is shown how Cohen′s later critique of Kant can be understood against this background. In the third part I suggest interpreting Cohen′s logic along the lines of Robert Brandoms inferentialism. It is the declared intention of both philosophers to explain the origin of the content of epistemic claims without making use of any claim about mental representations. The article ends with a comparison of Cohen′s and Sellars′ visions of the systematic character of philosophy. It is argued that while both assume the compatibility of scientific realism with an irreducibly normative ethics, Cohen′s approach is more ambitious, insofar as it requests ethics to develop its own ethical theory of man, the task of which is to overcome the mythical presuppositions of our common sense views on morals.

Die Wissenschaftsphilosophie als eigenständige philosophische Disziplin ist relativ jung. Ohne Anspruch auf Genauigkeit lassen sich ihre Anfänge auf das letzte Drittel des 19. Jahrhunderts datieren. Einen in der zeitgenössischen Diskussion lange vergessenen Ansatz der frühen Wissenschaftsphilosophie bilden die verschiedenen Strömungen des Neukantianismus, der bis in die ersten Jahrzehnte des 20. Jahrhunderts in Deutschland eine dominierende Rolle spielte.

This article concerns genealogy of ideas from the Marburg school of neo-Kantian philosophy in’s early works in the context of intellectual and educational tendencies in Europe and the Russian Empire at the turn of the 20th century. Yevhen Spektorskyi (1875–1951) is known as a prominent philosopher and lawyer, professor, and the last president at the Saint Volodymyr University. Analyzing his early works, which were strongly connected to his teaching and scientific activities at the law faculty of Warsaw University, the (...) author recognizes several key factors as the reasons for considerable development of the main neo-Kantian ideas of the philosopher. Firstly, Spektorskyi’s research interests were strongly influenced by the intellectual communication with his teacher, professor, and lawyer Oleksandr Blok (1852–1909), whose research was concentrated on the idea of classification of the sciences and its further substantiating. Secondly, we know that at the beginning of 20th century Spektorskyi was on several long-term educational secondments in European educational institutions, which allowed him to immerse into intellectual life of that time. In the article, the author focuses on analysis of Spektorskyi’s published works and unpublished manuscripts of the years 1903–1910. It is clarified that their main issues concern essential notions and arguments of critical idealism and its implications for the procedures of rational argumentation of sciences (mainly, social sciences) by setting ideal goals and clarification of regulative ideas for the social scientists in their research. The article also examines Spektorskyi’s logical structure of critique of the founder of the Marburg school of Neo-Kantianism Hermann Cohen (1842–1918). The critique concerns the development of ethics as “mathematics of natural science” and argues for the creative and productive rethinking of neo-Kantian ideas by Spektorskyi. (shrink)

Widmer sheds light on a neglected aspect of the Western philosophical tradition. Following an era of Hegelianism, the members of the neo-Kantian "Marburg School," such as Friedrich Albert Lange, Hermann Cohen, Rudolf Stammler, Paul Natorp, and Ernst Cassirer defended socialism or left-wing ideals on Kantian principles. In doing so, Widmer breaks with two mistaken assumptions. First, Widmer demonstrates that the left-Hegelian and Marxist traditions were not the only significant philosophical sources of socialist critique in nineteenth-century Germany, as the left-Kantians (...) identified problems of normativity that the left-Hegelians could not adequately address. Second, Widmer challenges the prevailing assumption that the political philosophies developed in the Marburg School can be comprehensively characterized as a unified school of "ethical socialism." By showing that they varied fundamentally regarding their political views and their philosophical foundations of socialism, Widmer fills a gap in the studies of neo-Kantianism that is long overdue.

After the completion of I. Kant’s “Copernican” turn in metaphysics, all subsequent European philosophy to one degree or another was under his influence. The purpose of the article is to consider the reception and transformation of the Kantian theoretical philosophy by the Marburg school of neo-Kantianism. It is necessary to analyze the reasons for H. Cohen's and P. Natorp’s interpretation of Kant's criticism. To do this, one should consider (i) internalist and (ii) externalist factors in the formation of the (...) Marburg School. Neo-Kantianism, on the one hand, emerged as a response to materialism, naturalism, and post-Kantian German idealism. In addition, the Marburg School was strongly influenced by the change in the scientific paradigm in mathematical natural science at the end of the 19th century. The justification by the Marburgers of Kant’s a priori doctrine presupposed thematization, first of all, of: a) purity of thought; b) systematic unity of thought and experience; c) the orientation of philosophy to the “fact of science”; d) transcendental method. As a result, the Marburg School interpreted the Kantian concept of the unity of consciousness; abandoned the principle of synthetic (real) unity of consciousness in favor of systematic (logical) unity; substantiated the purity of scientific thinking; put forward the requirement of orientation of philosophy to the “fact of science”; developed the concept of the origin of thinking (Ursprung); abandoned the idea of “givenness” of the subject of knowledge and proved its “assignment”; changed the understanding of the essence and functions of the transcendental method; put forward the concept of thinking as “generation” (“production”); formulated a new understanding a priori. The changes that took place in the 19th century in philosophy, mathematical natural science and mathematical sciences led to a sharp activation of constructivism. It can be concluded that Kant’s epistemological paradigm was realistic constructivism. Pure constructivism became the paradigm of the Marburg School. (shrink)

ZusammenfassungIm Mittelpunkt des Beitrags steht die Übertragung ausgewählter Kapitel aus den 1955 niedergelegten autobiographischen Erinnerungen des japanischen Bakteriologen Taichi Kitashima, in denen Kitashima stark persönlich gefärbt über seinen Aufenthalt in Marburg berichtet. Wie andere japanische Mediziner seiner Generation verbrachte Kitashima mehrere Jahre in Deutschland, um dort bei dem Serumforscher Emil von Behring zu arbeiten und sich weiterzubilden. Der Kontakt war über Kitashimas Lehrer Shibasaburô Kitasato zustande gekommen, mit dem Behring in Berlin über Fragen der Immunologie geforscht hatte. Im „Kommentar“ (...) wird diskutiert, inwieweit die von Kitashima in der zeitlichen Distanz von 50 Jahren getroffene Einschätzung des Deutschlandaufenthalts als „vergeudete Zeit“ als zutreffend anzusehen ist, welche Vorteile ihm aus den europäischen Kontakten, zu denen auch Begegnungen im Pariser Pasteur-Institut gehörten, erwuchsen und aus welchen Gründen sie im Nationalsozialismus wiederbelebt wurden.

In A Parting of the Ways Michael Friedman proposed to conceive the contemporary divide between analytic philosophy (AP) and continental philosophy (CP) as the outcome of the bifurcation between the Neokantians of Heidelbarg and Marburg. According to Friedman, Carnap can be characterized as the executor of the Marburg school, while Heidegger is to be considered as the heir of the Southwest Neokantianism. In this paper it is argued that Carnap was much closer to the Southwest Neokantianism than usually (...) recognized. To some extent, Carnap’s project in the Aufbau may be described as an attempt to modernize the Neokantian approach of the Southwest school with the help of modern relational logic. This entails that Carnap cannot be lined so easily with the Marburg school as Friedman assumes. (shrink)

Analyzes the philosophical ideas of two famous neo-Kantian philosophers, Hermann Cohen and Paul Natorp, who worked together in the Marburger Schule research institute from 1880 to 1912. In volume 1, mentions differences of opinion between them, partly due to Cohen's Jewishness, noting that Cohen resented the prevalence of antisemitism and discrimination. Cohen felt that Natorp's opposition to his ideas was motivated by antisemitism. The second volume is a collection of documents and correspondence between the two and others, where antisemitism is (...) frequently mentioned (see the index). (shrink)

Filling a gap in scholarship on 19th- and 20th-century religious thought, this book discusses the philosophy and theology of the influential Marburg School in Germany before 1914, focusing on the writings of Hermann Cohen, its leader, and on the Ritschlian theologian Wilhelm Herrmann, Karl Barth's teacher. In addition, Fisher examines Barth's earliest writings and clarifies the little-known liberal phase of Barth's theology.

Alongside the 'critical theory' of the Frankfurt School, West Germany was also home to another influential Marxist current known as the Marburg School. In this volume, Marburg disciple Lothar Peter traces the school's history and situates it in the political discourse and developments of its time. The renowned political scientist Wolfgang Abendroth plays a large role, but unlike most histories of the Marburg School Peter also takes the sociologists Werner Hofmann and Heinz Maus into account as well (...) as their many students and successors. They were united by the conviction that teaching and scholarship must necessarily be tied to the practical goal of transforming society - an approach that met with considerable opposition in the harshly anti-Communist atmosphere of the period.

These outbreaks can be seen as a paradigm for ethical issues posed by epidemic emergencies, through the convergence of such themes as: isolation and quarantine, privacy and confidentiality and the interpretation of ethical norms across different ethnocultural settings. With an emphasis on the boundaries between public health investigations and research, this article reviews specific challenges, past practices and current normative documents relevant to the application of ethical standards in the course of outbreaks of filovirus hemorrhagic fevers. Aside from commonly identified issues of informed consent and institutional review processes, we argue for more clarity over the specification of which communities are expected to share benefits, and we advocate for the use of collective definitions of duty to care and standard of care. We propose new elaborations around existing normative instruments, and we suggest some pathways toward more comprehensive approaches to the ethics of research in outbreak situations.

In 1912, Ernst Cassirer contributed to the special issue of the Kant-Studien that honored Hermann Cohen's retirement—his mentor and teacher, and the recognized founding father of the so-called 'Marburg school' of Neo-Kantianism. In the context of an otherwise rather conventional presentation of Cohen's interpretation of Kant, Cassirer made a remark that is initially surprising. It is “anything but accurate,” he wrote, to regard Cohen's philosophy as focused “exclusively on the mathematical theory of nature,” as is usually done. A reconstruction (...) of the genesis of Cohen's thought, Cassirer continued, would already refute this interpretation. Actually, “[t]he... (shrink)
