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.

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.

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)

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.

Norman Sieroka’s book is about “the systematic, structural relations between phenomenological and (neuro)physiological aspects of perception, consciousness, and time, with a specific focus on hearing” (p. 4), based on Leibniz’s and Husserl’s views. While Sieroka displays a great depth of knowledge in his discussions of these two philosophers, his main aims are not exegetic, but consist, rather, in casting new light on the said philosophical and interdisciplinary issues. However, the scope of his interpretative project is ambitious. There (...) is, on the one hand, Husserl, the founder of phenomenology, for whom perception is, first and foremost, conscious. On the other hand, there is Leibniz, the great rationalist metaphysician, who stands out in his era for bringing center-stage various kinds of unconscious perception. Sieroka effectively reconciles these seemingly very different perspectives, as he argues for numerous points of similarity between them and synthesizes them for mutual enrichment. (shrink)

In this book by the award-winning author of Just Healthcare, Norman Daniels develops a comprehensive theory of justice for health that answers three key questions: what is the special moral importance of health? When are health inequalities unjust? How can we meet health needs fairly when we cannot meet them all? Daniels' theory has implications for national and global health policy: can we meet health needs fairly in ageing societies? Or protect health in the workplace while respecting individual liberty? (...) Or meet professional obligations and obligations of justice without conflict? When is an effort to reduce health disparities, or to set priorities in realising a human right to health, fair? What do richer, healthier societies owe poorer, sicker societies? Just Health: Meeting Health Needs Fairly explores the many ways that social justice is good for the health of populations in developed and developing countries. (shrink)

How should medical services be distributed within society? Who should pay for them? Is it right that large amounts should be spent on sophisticated technology and expensive operations, or would the resources be better employed in, for instance, less costly preventive measures? These and others are the questions addreses in this book. Norman Daniels examines some of the dilemmas thrown up by conflicting demands for medical attention, and goes on to advance a theory of justice in the distribution of (...) health care. The central argument is that health care, both preventive and acute, has a crucial effect on equality of opportunity, and that a principle guaranteeing equality of opportunity must underly the distribution of health-care services. Access to care, preventive measures, treatment of the elderly, and the obligations of doctors and medical administrations are fully discussed, and the theory is shown to underwrite various practical policies in the area.

Of all the major philosophical works, Kant's Critique of Pure Reason is one of the most rewarding, yet one of the most difficult. Norman Kemp Smith's Commentary elucidates not only textural questions and minor issues, but also the central problems which arise, he contends, from the conflicting tendencies of Kant's own thinking. Kemp Smith's Commentary continues to be in demand with Kant scholars, and it is being reissued here with a new introduction by Sebastian Gardner to set it in (...) its contemporary context. (shrink)

This is the first book to gather the key writings of the distinguished political theorist Norman Geras into a single volume, providing a comprehensive overview of the thinking of one of the most important Marxist philosophers in the post-war era. Among the essays included here are 'The Controversy about Marx and Justice', 'The Duty to Bring Aid', 'Primo Levi and Jean Amery: Shame' and the contentious 'Euston Manifesto', which lays down a set of central principles for the democratic left (...) in the twenty-first century. The reader is rounded out with several posts from Geras's much-loved and widely read 'Normblog', as well as companion essays by Alan Johnson and Terry Glavin, which explore how Geras's philosophical concerns led to his more recent, trenchant critiques of the direction of left-wing politics.

This comprehension interpretation of Plato’s Euthyphro illuminates the necessary tension between tradition and autonomy in human and political life. Norman J. Fischer II argues that the dialogue defends Socrates by revealing the weaknesses of his opponents’ understanding of piety and the human soul, implicitly arguing for a Socratic alternative.

An accessible and enjoyable introduction to Zen Buddhist practice--in a reader-friendly question-and-answer format--by two highly regarded teacher-writers. The question-and-answer format makes this introduction to Zen especially easy to understand--and also to use as a reference, as you can easily look up just the question you had in mind. The esteemed Zen teacher Norman Fischer and his old friend and teaching colleague Susan Moon (both of them in the lineage of Shunryu Suzuki, author of Zen Mind, Beginner's Mind) give this (...) collaborative effort a playful tone: Susan asks a question on our behalf, Norman answers it, and then Sue challenges him. By the time you get through their conversations, you'll have a good basic education in Zen--not only the history, theory, and practice but also the contemporary issues, such as gender inequality, sexual ethics, and the tension between Asian traditions and the modern American reality.

"In his study of Philo Mr. Bentwich has done good service by demonstrating this characteristically Jewish combination of qualities in the spirit of the great Alexandrine, and by vindicating the claim of Philo to rank among the great teachers of Judaism." -The Jewish Review "Philo, the chief light of Hellenistic Judaism, by a strange fate was rejected and forgotten by his own people, while he was taken up by the Christians and almost adopted as one of their own. This difference (...) of attitude towards him on the part of Jews and Christians is easily explained. Philo was alien in spirit to the narrow rabbinical Judaism which became universal among the Jews in the second century after Christ, and hence was suspected as unorthodox and put under the ban. On the other hand, his philosophy and exegetical method appealed to the early Fathers, especially those of the Alexandrian school, and even much of his religious teaching was more in sympathy with Christian than with later Jewish thought. In modern times, however, Jewish sentiment towards this illustrious coreligionist has undergone considerable change. In the volume before us Mr. Norman Bentwich has undertaken to make him better known among his own people, and to remove any prejudice that might still exist against him by showing that, after all, he was a true Jew. Though the work is written for Jews, and, as the author frankly tells us, from a Jewish standpoint, by reason of its subject it is likely to attract also some Gentile readers." -America "Having specialized in Jewish history and literature, Mr. Bentwich was eminently fitted to undertake the work on Hellenism. It is this movement in Judaism which Mr. Bentwich has set himself to describe. During the last two or three centuries before the common era the Jewish people came in close contact with the Greek-speaking world, and naturally, could not entirely escape its influence. Greek thought prevailed throughout the Eastern world, and Hellenism, or the culture of Greece, for which Hellas is the older name, dominated the intellectual activity of men. Although the Jews were always opposed to foreign influences which conflicted with their mode of thinking, the Greek culture nevertheless penetrated Jewish life in one way or another....The struggle of Judaism with Hellenistic culture marks one of the most fundamental conflicts in the march of civilization, and as a result, Hellenistic Judaism is one of the most remarkable contributions to Jewish genius to the world's thought....The author treats this subject from the Jewish point of view. Others are chiefly interested in the relation of Hellenism to Christianity. The school of writers contrast the broad universalism of Hellenistic Judaism with the supposed narrow legalism of the Pharisees which eventually prevailed in Palestine. Mr. Bentwich combats this attitude. The present volume is popular in character and the author has not refrained from pointing out parallels in modern Jewish life....Mr. Bentwich apart from giving historical descriptions of the various phases of Hellenism in Palestine and in the Diaspora, fully describes the literature produced by the Jews during that period. He graphically and minutely describes the life and works of Philo, Josephus and other important Jewish writers. He gives a fine resume of the wisdom of Ben Sira and also, deals with the influence of the Septuagint and the attitude of the Jewish Rabbis toward it. The book will appeal to the cultured layman who wishes to be informed on the various movements of Judaism." -The Advocate: America's Jewish Journal. (shrink)

A prominent Zen teacher offers a “direct, penetrating, and powerful” perspective on a popular mind training practice of Tibetan Buddhism (Rick Hanson, author of Buddha’s Brain) Lojong is the Tibetan Buddhist practice of working with short phrases (called "slogans") to generate bodhichitta, the heart and mind of enlightened compassion. With roots tracing back to the 900 A.D., the practice has gained more Western adherents over the past two decades, partly due to the influence of American Buddhist teachers like Pema Chödrön. (...) Its effectiveness and accessibility have moved the practice out of its Buddhist context and into the lives of non-Buddhists across the world. It's in this spirit that Norman Fischer offers his unique, Zen-based commentary on the Lojong. Though traditionally a practice of Tibetan Buddhism, the power of the Lojong extends to other Buddhist traditions—and even to other spiritual traditions as well. As Fischer explores the 59 slogans through a Zen lens, he shows how people from a range of faiths and backgrounds can use Lojong to generate the insight, resilience, and compassion they seek.
