The so-called quantum Zeno effect is essentially a consequence of the projection postulate for ideal measurements. To test the effect, Itanoet al. have performed an experiment on an ensemble of atoms where rapidly repeated level measurements were realized by means of short laser pulses. Using dynamical considerations, we give an explanation why the projection postulate can be applied in good approximation to such measurements. Corrections to ideal measurements are determined explicitly. This is used to discuss how far the experiment of (...) Itanoet al. can be considered as a test of the quantum Zeno effect. We also analyze a new possible experiment on a single atom where stochastic light and dark periods can be interpreted as manifestation of the quantum Zeno effect. We show that the measurement point of view gives a quick and intuitive understanding of experiments of the above type, although a finer analysis has to take the corrections into account. (shrink)

Druck der Zensur, nicht Aufhebung der Zielvorstellungen ist die richtige Begründung für das Vorherrschen der ober-flächlichen Assoziationen. Die oberflächlichen Assoziationen ersetzen in der Darstellung die tiefen, wenn die Zensur diese normalen Verbindungswege ungangbar macht. Es ist, wie wenn ein allgemeines Verkehrshindernis, z.B. eine Überschwemmung, im Gebirge die großen und breiten Straßen unwegsam werden läßt; der Verkehr wird dann auf unbequemen und steilen Fußpfaden aufrechterhalten, die sonst nur der Jäger begangen hat.

Hermann Cohen’s essay on Maimonides’ ethics is one of the most fundamental texts of twentieth-century Jewish philosophy, correlating Platonic, prophetic, Maimonidean, and Kantian traditions. Almut Sh. Bruckstein provides the first English translation and her own extensive commentary on this landmark 1908 work, which inspired readings of medieval and rabbinic sources by Leo Strauss, Franz Rosenzweig, and Emmanuel Levinas. Cohen rejects the notion that we should try to understand texts of the past solely in the context of their own historical (...) era. Subverting the historical order, he interprets the ethical meanings of texts in the light of a future yet to be realized. He commits the entire Jewish tradition to a universal socialism prophetically inspired by ideals of humanity, peace, and universal justice. Through her own probing commentary on Cohen’s text, like the margin notes of a medieval treatise, Bruckstein performs the hermeneutical act that lies at the core of Cohen’s argument: she reads Jewish sources from a perspective that recognizes the interpretive act of commentary itself.

Health is a value-laden concept. The state of being that it designates is a fundamental human goal. As a value, the concept is normative, governing both clinical practice and the therapeutic treatment developed by medical research. Also, the promise of health plays a pivotal role in health-policy discourse. Almut Caspary considers philosophical and theological concepts of health in the context of its practical significance, both in the past and today. This conceptual analysis culminates in a preliminary sketch of a (...) concept of health; focusing on the stem-cell debate, it offers a discriminating approach to contemporary ethical problems in medicine. "Gesundheit" ist ein wertgeladener Begriff. Er bezeichnet einen grundsatzlich wunschenswerten Zustand menschlicher Existenz, der das arztliche Handeln im klinischen Alltag leitet. Daruber hinaus werden (gesundheits-)politische Debatten mit Verweis auf den Nutzen fur die Gesundheit entschieden. Vor diesem Hintergrund setzt sich Almut Caspary epochenubergreifend mit philosophischen und theologischen Uberlegungen zur Gesundheit auseinander. Die konzeptuelle Diskussion erlaubt die Skizzierung eines Gesundheitsverstandnisses, das - wie am Beispiel der Stammzelldebatte gezeigt wird - ein differenziertes Abwagen in medizinethischen Konfliktfallen zulasst.

The strict distinction and separation of mind and body is a particularly modern Western point of view that is routinely also applied to other cultures. Arguing against this dichotomy, the following contribution builds upon research on "implicit knowledge" and "knowing how" that allow us to view body and mind in their interaction. The focus is on Simeon Stylites the Elder, the most prominent representative of the Syrian ascetic movement, who, in a spectacular way and after incessant exercise, was able to (...) act from a sphere of internalized body-knowledge. Selected texts on him dating from Late Antiquity will illustrate how the ascetic body was represented as a body of knowledge with which the idea of Christian perfection was to be fulfilled. (shrink)

The speech of Gregory Thaumaturgus to the Christian scholar and theologian Origen is a historical document of unusual importance, both in terms of its content, depicting the master-student relationship of the time from the perspective of the student, and in terms of form, providing an actual implementation of the theory of rhetoric that was a cornerstone of higher education. Yet disagreement persists to this day in the scholarly literature over the generic classification of this first example of Christian epideictic oratory. (...) It is most frequently found categorized as a speech of thanksgiving, of praise, or of farewell. This paper discusses the grounds for the various definitions, examines the text itself in search of such grounds, and shows, in reference to two treatises on epideictic attributed to Menander Rhetor, why the most plausible classification is as a logos syntaktikos – a farewell speech, in which a traveler, by means of portraying and arousing emotion, laments the necessary parting and praises the person or people of whom leave is taken.

In both ancient tradition and modern research Pythagoreanism has been understood as a religious sect or as a philosophical and scientific community. Numerous attempts have been made to reconcile these pictures as well as to analyze them separately. The most recent scholarship compartmentalizes different facets of Pythagorean knowledge, but this offers no context for exploring their origins, development, and interdependence. This collection aims to reverse this trend, addressing connections between the different fields of Pythagorean knowledge, such as eschatology, metempsychosis, metaphysics, (...) epistemology, arithmology and numerology, music, dietetics and medicine as well as politics. In particular, the contributions discuss how the Pythagorean way of life related to more doctrinal aspects of knowledge, such as Pythagorean religion and science. The volume explores the effects of this interdependence between different kinds of knowledge both within the Pythagorean corpus and in its later reception. Chapters cover historical periods from the Archaic Period (6th century BC) to Neoplatonism, Early Christianity, the European and Arabic Middle Ages, and the Renaissance through to the Early Modern Period (17th century AD).

Wann habe ich zu existieren begonnen? Mit der Geburt? Mit der "Empfangnis"? Oder noch davor? Wenige Fragen beruhren unser Selbstverstandnis so sehr wie diese. Diesen Fragen wird transdisziplinar theologisch-philosophisch-naturwissenschaftlich nachgegangen. Gezeigt wird, welcher Status dem Vorgeburtlichen in Geschichte und Gegenwart zugeschrieben wurde bzw. wird; Begriffe wie "biologisches Individuum", "Spezies" und "aktive Potenz" werden geklart; sodann wird diskutiert, welche ontogenetischen Ereignisse als "Beginn" - sei es des Organismus, des Individuums, des Menschen oder der Person - taugen.

Abstract„Erleuchtung“ ist einer der prominentesten Begriffe, mit dem in der europäischen Kultur- und Religionsgeschichte Ideen der Vervollkommnung des Menschen zum Ausdruck gebracht worden sind. Anhand ausgewählter Beispiele umreißt das vorliegende Papier seine Entwicklung von einer Metapher in der griechischen Philosophie hin zu einem transkonfessionellen Sammelbegriff, der im Zuge der Pluralisierung von Religionen seit den 1960er Jahren eine Konjunktur in neuen, durch Markt und Medien allgemein zugänglichen Sinnstiftungsangeboten der „populären Religion“ (Knoblauch) erfahren hat. In einer Tour d’horizon, die bei Platon einsetzt (...) und über Clemens von Alexandrien und Ps.-Dionysios Areopagita ins 18. Jahrhundert sowie in die Gegenwart führt, wird gezeigt, wie sich Vorstellungen von Licht und Erleuchtung und die Rede hierüber zu einem religiösen Begriff verdichtet haben, der über lange Zeit einen Ort im Christentum hatte, bevor er, begünstigt durch die Aufklärung, zu einer populären Kategorie wurde, die vor allem mit asiatischen, oder zumindest asiatisch inspirierten, Praktiken zur Erlangung von Heil in Verbindung gebracht wird. Der Beitrag rückt bei der Darstellung dieser Entwicklung in der Moderne Auswirkungen der Aufklärung in den Blick sowie asiatisch-euroamerikanische Beziehungsdynamiken der europäischen Kolonialzeit, die zur Entdeckung des Buddhismus als Religion führten. Haben diese doch maßgeblich dazu beigetragen, dass Erleuchtung im gegenwärtigen populären Verständnis, wie es sich beispielhaft in der sog. Satsang-Bewegung und populär-religiöser Erzähl- und Ratgeberliteratur findet, nicht mehr, wie in der neoplatonischchristlichen Prägung des Begriffs, als Zwischenstufe auf einem Weg zur Vervollkommnung gilt, sondern als Ziel und bleibender Besitz, der mit Vollendung assoziiert wird.

The link between justice and climate change is becoming increasingly prominent in public debates on climate policy. This clear and concise philosophical introduction to climate justice addresses the hot topic of climate change as a moral challenge. Using engaging everyday examples the authors address the core arguments by providing a comprehensive and balanced overview of this heated debate, enabling students and practitioners to think critically about the subject area and to promote discussion on questions such as: Why do anything in (...) the face of climate change? How much do we owe our descendants – a better world, or nothing at all? How should we distribute the burden of climate action between industrialized and developing countries? Should I adopt a green lifestyle even if no one else makes an effort? Which means of reducing emissions are permissible? Should we put hope in technological solutions? Should we re-design democratic institutions for more effective climate policy? With chapter summaries, illustrative examples and suggestions for further reading, this book is an ideal introduction for students in political philosophy, applied ethics and environmental ethics, as well as for practitioners working on one of the most urgent issues of our time.

The adoption of the French Duty of Vigilance law has been celebrated as a milestone for advancing the transnational business and human rights regime. The law can contribute to harden corporate accountability by challenging the “separation principle” of transnational companies and by obligating companies to report on their duty of vigilance. However, the question of whether the law actually contributes to human rights and environmental protection along global supply chains requires empirically grounded research that connects processes in home and host (...) state countries. This paper contributes to such a new research agenda by linking political ecology literature and empirical insights from the Global South to research on due diligence regulations. With reference to field research data on contestations between the oil and gas company Total E&P and indigenous communities in Bolivia, I argue that the burden of proof and contestations over valid knowledge represent major obstacles when trying to establish legal liability.

The Deontic Transfer Principle states that if it is permissible for a person A to cause another person B harm H then, other things being equal, it is permissible for A to impose a risk of harm H on B. In this article we show that the Deontic Transfer Principle is vulnerable to counterexamples, and that the same is true of a range of closely related principles. We conclude that the deontic status of a risk imposition is not directly inherited (...) from the deontic properties of deterministic acts. (shrink)

In this paper, we will discuss Peter van Inwagen’s contribution to the epistemological debate about revealed peer disagreement. Roughly, this debate focuses on situations in which at least two participants disagree on a certain proposition based on the same evidence. This leads to the problem of how one should react rationally when peer disagreement is revealed. Van Inwagen, as we will show, discusses four possible reactions, all of which he rejects as unsatisfying. Our proposal will be to point to hidden (...) assumptions in van Inwagen’s reasoning and ask whether he is willing to reject at least one of these to get rid of the problem. In short, our thesis amounts to the following: Of the two epistemological claims, which we call “Weak” and “Full-blown Fallibilism”, van Inwagen cannot simultaneously accept the first and reject the latter, while this is what he seems to suggest. Revealing this potential dilemma for van Inwagen’s position will lead to a more detailed discussion of how “rationality”, “truth”, “evidence” and “justification” interrelate and how a closer look at their relation might help solving the puzzle of revealed peer disagreement.

The recently much discussed phenomenon of testimony as a social source of knowledge plays a crucial justificatory role in Richard Swinburne's philosophy of religion. Although Swinburne officially reduces his principle of testimony to the criterion of simplicity and, therefore, to a derivative epistemic source, we will show that simplicity does not play the crucial role in this epistemological context. We will argue that both Swinburne's philosophical ideas and his formulations allow for a fundamental epistemic principle of testimony, by showing that (...) Swinburne has already implicitly justified the use of testimony as an epistemic source via his fundamental a priori principle of credulity. (shrink)

In this paper I will introduce a practical explication for the notion of expertise. At first, I motivate this attempt by taking a look on recent debates which display great disagreement about whether and how to define expertise in the first place. After that I will introduce the methodology of practical explications in the spirit of Edward Craig’s Knowledge and the state of nature along with some conditions of adequacy taken from ordinary and scientific language. This eventually culminates in the (...) respective explication of expertise according to which this term essentially refers to a certain kind of service-relation. This is why expertise should be considered as a predominantly social kind. This article will end up with a discussion of advantages and prima facie plausible objections against my account of expertise. (shrink)

Philip Kitcher’s account of scientific realism in 'The Advancement of Science' (AS) differs from his account in 'Science, Truth and Democracy' (STD). We demonstrate that (1) contrary to appearance, Kitcher in AS proposes a so-called Kantian realism that is accompanied not by a correspondence theory, but by a hybrid conception of truth. (2) Also, we point out that Kitcher does not pertain to the “promiscuous realism” proposed in STD stringently, but falls back on his Kantian realism of AS at points. (...) Here, we question Kitcher’s claim that his promiscuous-realist conception stems initially from commonsensical be-liefs. (shrink)

Are our beliefs justified only relatively to a specific culture or society? Is it possible to give reasons for the superiority of our scientific, epistemic methods? Markus Seidel sets out to answer these questions in his critique of epistemic relativism. Focusing on the work of the most prominent, explicitly relativist position in the sociology of scientific knowledge – so-called 'Edinburgh relativism' or the 'Strong Programme' –, he scrutinizes the key arguments for epistemic relativism from a philosophical perspective: underdetermination and (...) norm-circularity. His main negative result is that these arguments fall short of establishing epistemic relativism. -/- Despite arguing for epistemic absolutism, Seidel aims to provide an account of non-relative justification that nevertheless integrates the basic, correct intuition of the epistemic relativist. His main positive result is that the epistemic absolutist can very well accept the idea that people using different standards of justification can be equally justified in holding their beliefs: Rational disagreement, he maintains, is perfectly possible. -/- The book provides a detailed critique of relativism in the sociology of scientific knowledge and beyond. With its constructive part it aims at making conciliatory steps in a highly embittered discussion between sociology and philosophy of science. (shrink)

One third of all materials extracted from the Earth is used in the furniture industry. Of these, timber counts for 25%: the furniture industry is key to save one of the most important commons – our forest. Starting from the assumption that a better knowledge of consumers’ attitude and behaviour towards sustainable furniture is essential to spur the industry all along the chain to take action towards more sustainable operations, this study explores the actual offer of sustainable furniture in the (...) Netherlands and consumers’ attitude towards it in order to determine opportunities for the furniture sector to take a more sustainable stance. (shrink)
