We take up the challenge of developing an international network with capacity to survey the world's scientists on an ongoing basis, providing rich datasets regarding the opinions of scientists and scientific sub-communities, both at a time and also over time. The novel methodology employed sees local coordinators, at each institution in the network, sending survey invitation emails internally to scientists at their home institution. The emails link to a ‘10 second survey’, where the participant is presented with a single statement (...) to consider, and a standard five point Likert scale. In June 2023, a group of 30 philosophers and social scientists invited 20,085 scientists across 30 institutions in 12 countries to participate, gathering 6,807 responses to the statement 'Science has put it beyond reasonable doubt that COVID-19 is caused by a virus'. The study demonstrates that it is possible to establish a global network to quickly ascertain scientific opinion on a large international scale, with high response rate, low opt-out rate, and in a way that allows for significant (perhaps indefinite) repeatability. Measuring scientific opinion in this new way would be a valuable complement to currently available approaches, potentially informing policy decisions and public understanding across diverse fields.

In Humanism in Intercultural Perspective, editors Jörn Rüsen and Henner Laass outline their project of renewing the foundations of the notion of “humanism.” They collect a large variety of contributions they hope will be conducive to this aim. Yet the architecture of the project leaves open a long list of conceptual problems, concerning in particular: the integration of cultural diversity into humanism; the relationship between humanism and the political; the way in which normativity is incorporated into humanism; and the question (...) as to the place of historicity in the human condition. An extended discussion of Elisio Macamo's, Dipesh Chakrabarty's, and Friedrich Wilhelm Graf's contributions to the volume serves to further elucidate these problems and to explore ways in which they might possibly be solved.

The political scientist and former Bavarian Minister of Culture Hans Maier has created a historically profound, theologically educated, literarily and musically highly sensitive, politically mature body of work, with which he has inscribed himself in the (intellectual) history of the Federal Republic. This book is the first to contain contributions by renowned scholars and politicians on the rich work and impact of the Catholic scholar and politician Hans Maier. It thematises and appreciates in detail his view of German history and (...) the traditions of political thought, his critique of political language, political theology, totalitarianism and political religions, but also his contributions on Catholicism and modernity, his writings on literature and music, and finally his influence as an academic teacher, public intellectual and politician. With contributions by Udo Bermbach, Thomas Brose, Ahmet Cavuldak, Horst Dreier, Hermann-Josef Große Kracht, Jens Hacke, Oliver Hidalgo, Hans Günter Hockerts, Patrick Horst, Horst Möller, Heinrich Oberreuter, Henning Ottmann, Mark Edward Ruff, Hans Otto Seitschek, Michael Stolleis, Bernhard Vogel, Peter Graf von Kielmansegg, Theo Waigel and Markus Zimmermann.

Das mir vorgegebene Thema lautete: “The Significance of Troeltsch’s Soziallehren for the Present”’. Im ersten Teil skizziere ich die Genese von Troeltschs christentumshistorischem Hauptwerk. Im zweiten Teil geht es um die zentralen Themen seines “Lieblingsbuches”. Im dritten Teil werden einige seiner handschriftlichen Zusätze und Marginalien kurz vorgestellt, (...) die die 2020 erscheinende Kritische Ausgabe der “Soziallehren” erstmals zugänglich macht. Abschließend entfalte ich eine Antwort auf die Frage, warum es sich auch heute noch lohnt, Ernst Troeltsch zu lesen. (shrink)

By the end of April 1923, Paul Tillich’s Das System der Wissenschaften nach Gegenständen und Methoden (1981: The System of the Sciences according to Objects and Methods) was published by the German publishing house Vandenhoeck & Ruprecht in Göttingen. Based on numerous source documents from the publishers’ archives and particularly on the correspondence between the publishers Wilhelm and Gustav Ruprecht, hitherto unknown but now edited and commented on here, the present article explains that Tillich wrote his System of the Sciences (...) primarily for the publisher. It was Emanuel Hirsch who established the connection between them as the publishing house was looking for a new editor for their popular series Wege zur Philosophie (Ways to Philosophy), published since 1911. After Hirsch having brought Tillich into play, Wilhelm Ruprecht could convince the Berlin “Privatdozenten” to become the new editor of the series. As to the series, Tillich unfolded the concept of a comprehensive system design which covered 65 topics, i. e. forthcoming volumes. When the publisher then demanded that Tillich prove his abilities to write comprehensively in common language by providing a sample of a first issue of the series, he began to work on his System der Wissenschaften. Although this text contained all sorts of ideas and concepts, it was certainly not very well suited as an introduction to a series of popular accounts of the central themes and matters of philosophy. In the end, the System was published, although not as a volume of the series as having been announced by the publishing house in 1922, but as a text in its own right. (shrink)

In June 1947 Paul Tillich signed a contract with The University of Chicago Press for a “Systematic Theology” in two volumes. Having published the first volume in April 1951, he asked the publisher to split the second volume into two parts, which were published in 1957 as volume II and 1963 as volume III. In this article the different editions of “Systematic Theology” are described, and the economic aspects of writing and publishing this very influential academic book are explained. Many (...) unknown sources are presented. Some of them show Tillich as an author in real despair. (shrink)

Within collective epistemology, there is a class of theories that understand the epistemic status of collective attitude ascriptions, such as ‘the college union knows that the industrial action is going to plan’, or ‘the jury justifiedly believes that the suspect is guilty’, as saying that a sufficient subset of group member attitudes have the relevant epistemic status. In this paper, I will demonstrate that these summativist approaches to collective epistemology are incompatible with epistemic permissivism, the doctrine that a single body (...) of evidence may rationalize multiple doxastic attitudes. In particular, I will make use of epistemic permissivism to provide a general recipe for generating so-called divergence cases, which demonstrate situations in which rationality requires group-level and member-level attitudes to diverge. I will call this class of cases permissive divergence cases. While other divergence cases have been discussed in the literature, permissive divergence cases prove themselves to be less susceptible to many of the worries raised against their competitors, while being directly built on an often-defended epistemological thesis.

_Focused on existentialism, this issue explores current writers, thinkers, and texts affiliated with the movement_ In 1948, _Yale French Studies_ devoted its inaugural issue to existentialism. This anniversary issue responds seventy years later. In recent years, new critical and theoretical approaches have reconfigured existentialism and refreshed perspectives on the philosophical, literary, and stylistic movement. This special issue restores the writers, thinkers, and texts of the movement to their subversive strength. In so doing, it illustrates existentialism’s present relevance, revealing how the (...) concerns of the past urgently bristle into our own times. (shrink)

Both in scholarship on the Weimar Republic and in historical research in general, many conceptions of ‘crisis’ tend to remain vague and difficult to operationalize. These operational defects of the concept of crisis arise inevitably, we argue, from the concept’s constitutive link to human perception on the one hand and from its subsumption of complex interconnections of historical processes within different subsystems on the other. Frequently today, in both ordinary and historiographical usage, this basic openness of the concept of crisis (...) is foreclosed when it is deployed with a solely negative connotation of ‘downfall’ and ‘decline’, or of something being thrown into question or jeopardy. Such uses obscure a way in which a crisis can evoke not only the pessimistic sense of a threat to the old order but also the optimistic scenario of a chance for renewal. A one-sidedly negative understanding of crisis as prelude to calamity, we argue here, is problematic for historical research for two reasons. Firstly, it obscures comprehension of the consciousness of actors in the relevant period who at any particular moment can have had no prior knowledge of the crisis’s outcome. Secondly, it tends to reify the relevant crisis and to occlude its basic character as something narratively constructed in the accounts of both contemporaries and subsequent historiography. (shrink)

This thesis is an investigation into the nature of epistemic justification. It brings together themes from traditional, individual-centred epistemology, and collective, group-centred epistemology. The first half of the thesis is concerned with the question of whether rationality is epistemically permissive; that is, whether one body of evidence can rationalise more than one doxastic attitude. In chapter 1, I argue that permissive cases are best understood as epistemic standard conflicts. Doing so provides us with a novel understanding of the arbitrariness objection (...) against permissivism and enables us to reduce questions about epistemic permissibility to questions about the nature of incommensurability. In chapter 2, I show that the defended understanding of permissive cases generalises by defending it against an objection from self-fulfilling beliefs. In chapter 3, I demonstrate that we can use this view of epistemic rationality to generate so-called divergence arguments which show that the epistemic status of group-level attitudes and member-level attitudes can rationally diverge. In the second half of the thesis, I develop a novel evidentialist theory of epistemic justification, called Continuous Evidentialism. Continuous Evidentialism is inspired by some general methodological reflections (chapter 4), which suggest that we should opt for a theory of epistemic justification that analyses the epistemic status of group-level attitudes and member-level attitudes continuously. According to Continuous Evidentialism, to have a justified belief is to possess sufficient evidence and utilise that evidence in an epistemically responsible way when forming the belief. While I argue that we can reduce epistemic responsibility to higher-order evidentialist requirements. In chapter 5, I develop a theory of evidence, evidence possession and epistemic basing. Chapters 6 - 8, discuss various complications of the proposed theory, having to do with the alleged defeasibility of justification (chapter 6), epistemic responsibility (chapter 7), and the proposed reduction of epistemic responsibility (chapter 8). In chapter 9, I compare Continuous Evidentialism to various extant accounts. (shrink)

Methods Young healthy heterosexual couples underwent sleep-lab-based polysomnography of two sleeping arrangements: individual sleep and co-sleep. Individual and dyadic sleep parameters (i.e., synchronization of sleep stages) were collected. The latter were assessed using cross-recurrence quantification analysis. Additionally, subjective sleep quality, relationship characteristics, and chronotype were monitored. Data were analyzed comparing co-sleep vs. individual sleep. Interaction effects of the sleeping arrangement with gender, chronotype, or relationship characteristics were moreover tested. Results As compared to sleeping individually, co-sleeping was associated with about 10% (...) more REM sleep, less fragmented REM sleep (p = 0.008), longer undisturbed REM fragments (p = 0.0006), and more limb movements (p = 0.007). None of the other sleep stages was significantly altered. Social support interacted with sleeping arrangement in a way that individuals with suboptimal social support showed the biggest impact of the sleeping arrangement on REM sleep. Sleep architectures were more synchronized between partners during co-sleep (p = 0.005) even if wake phases were excluded (p = 0.022). Moreover, sleep architectures are significantly coupled across a lag of ± 5min. Depth of relationship represented an additional significant main effect regarding synchronization, reflecting a positive association between the two. Neither REM sleep nor synchronization was influenced by gender, chronotype, or other relationship characteristics. Conclusion Depending on the sleeping arrangement, couple's sleep architecture and synchronization show alterations that are modified by relationship characteristics. We discuss that these alterations could be part of a self-enhancing feedback loop of REM sleep and sociality and a mechanism through which sociality prevents mental illness. (shrink)

A central concern of nearly every environmental ethic is its desire to extend the scope of direct moral concern beyond human beings to plants, nonhuman animals, and the systems of which they are a part. Although nearly all environmental philosophies have long since rejected modernity’s conception of individuals as isolated and independent substances, few have replaced this worldview with an alternative that is adequate to the organic, processive world in which we find ourselves. In this context, Brian G. Henning (...) argues that the often overlooked work of Alfred North Whitehead has the potential to make a significant contribution to environmental ethics. Additionally inspired by classical American philosophers such as William James, John Dewey and Charles Sanders Pierce and environmental philosophers such as Aldo Leopold, Peter Singer, Albert Schweitzer, and Arne Naess, Henning develops an ethical theory of which the seminal insight is called “The Ethics of Creativity.” By systematically examining and developing a conception of individuality that is equally at home with the microscopic world of subatomic events and the macroscopic world of ecosystems, _The Ethics of Creativity_ correctly emphasizes the well-being of wholes, while not losing sight of the importance of the unique centers of value that constitute these wholes. In this way, _The Ethics of Creativity_ has the potential to be a unique voice in contemporary moral philosophy. (shrink)

Bodily movement has a deeper meaning than modern sport science might recognize. It can have religious undertones, and in modern societies, it is sometimes related to the building of national identity. In the study, two cases of bodily practice are compared. Norwegian ski has a relation to friluftsliv (outdoor activities) and is highly significant for modern Norwegian identity. Indian yoga is related to the traditional ayurveda medicine and to Hindu spirituality, and obtained an important place in the process of anti-colonial (...) nationalism. The aim is to demonstrate how Norwegian skiing and Indian yoga as national body and movement cultures in different ways, show a complex connection between ‘ancient roots’ and modern transformations of cultural identity. Gliding on skis, sitting, and breathing in yoga make up the basis on which people have built identities of their collective ‘we’. (shrink)

Is phenomenology a method or a philosophy (of ?ontological? character)? This question is discussed here with a recent philosophical collection of articles about the phenomenology of sport at hand. However, one finds very few concrete phenomena in this volume, but much abstract talk about the authoritative philosophers of ontology and existentialism. This gives the ?phenomenological school? a somewhat sectarian character, which is not typical in recent contributions of phenomenology. This review essay broadens out from the current volume under consideration towards (...) a history of phenomenology and a differential phenomenology of phenomenology. It is not clear how much value the volume itself, however, has for the understanding of sport as well as for the understanding of phenomenology. Nevertheless, it documents how phenomenological scholastics approach sport, which may serve as a warning at a time when positivist reductionism seems to have also become mainstream in human and social sciences.

CSR has become an important element in the business strategy of a growing number of companies worldwide. A large number of initiatives have been developed that aim to support companies in developing, implementing, and communicating about CSR. The Global Compact (GC), initiated by the United Nations, stands out. Since its launch in 2000, it has grown to about 2900 companies and 3800 members in total. The GC combines several mechanisms to support CSR strategies: normative principles, networks for learning and co-operation, (...) and communication and transparency about CSR activities. However, up to now only a few empirical evaluations of the contribution of the GC to CSR strategies have been conducted that however have not differentiated between different types of companies (regarding type of industry or regarding the maturity of CSR). This paper aims to partly fill this knowledge gap by a case study examination of three frontrunner companies in the telecommunications industry. The results show that the GC is only one of the many initiatives that these companies employ in shaping, implementing, and reporting about their CSR strategies, and that its role is at most modest. There are two important reasons. One is that many of the CSR issues that these companies deal with are industry specific and are hence addressed in specific networks. The second reason is that the GC principles are perceived as minimum requirements that do not provide many incentives to the three case study companies to perform better. A differentiation of norms for GC members is expected to enhance the contribution of the GC to CSR strategy employment, not only for frontrunner companies but as well for other categories of companies.

Rational or epistemically justified beliefs are often said to be defeasible. That is, beliefs that have some otherwise justification conferring property can lose their epistemic status because they are defeated by some evidence possessed by the believer or due to some external facts about the believer’s epistemic environment. Accordingly, many have argued that we need to add a so-called no defeater clause to any theory of epistemic justification. In this paper, I will survey various possible evidentialist as well as responsibilitst (...) no-defeater clauses and develop a general taxonomy of defeater cases against which these clauses can be tested. Despite influential arguments that evidentialist understandings of justification are ill-equipped to handle the full spectrum of defeater cases, I will demonstrate that evidentialism has the right tools to make sense of all kinds of defeaters, including propositional and normative defeaters. Moreover, I will demonstrate that the proposed solution avoids recently influential objections against the notion of defeat. (shrink)

Thomas Nagel recognizes that it is commonly believed that people can neither be held morally responsible nor morally assessed for what is beyond their control. Yet he is convinced that although such a belief may be intuitively plausible, upon reflection we find that we do make moral assessments of persons in a large number of cases in which such assessments depend on factors not under their control. Of such factors he says: (p. 26).

Resumen: Este artículo presenta la visión epistémica alternativa expuesta por Adorno y Horkheimer en los “Elementos del antisemitismo”, contenidos en la Dialéctica de la Ilustración, visión que sostiene un acercamiento ensayístico a su objeto de estudio a manera de montaje. El texto está compuesto por siete tesis, interrelacionadas de manera no-determinante, formando una constelación conceptual alrededor del tema. A partir de esta estrategia, los autores se oponen a la forma hegemónica de producción de conocimiento que conciben como sistematizante y totalizante. (...) Haciendo justicia a esta propuesta, mi lectura del texto se ha constituido de la misma manera: desmontando y reagrupando las tesis de tal forma que dan cuenta de nuevas perspectivas interpretativas del fenómeno del antisemitismo, así como de aspectos omitidos en la recepción de la obra de Adorno y Horkheimer.: The present article gives account of the epistemic vision exposed by Adorno and Horkheimer in the “Elements of anti-Semitism”, a text contained in the Dialectics of Enlightenment: the authors introduce a notion of knowledge that sustains an essayistic approach to its object using the strategy of montage. “Elements of anti-Semitism” consists of seven theses, which are interrelated in a non-determinant way, forming a conceptual constellation around the issue. Through this strategy, the authors oppose the system as the hegemonic form of philosophical production, it is conceived by Adorno and Horkheimer annihilating difference ant therefore totalitarian. According to this, my reading of this text tries to do justice to this epistemological proposal by constituting it in the way the authors suggest: the theses were disassembled and re-grouped, in order to give account of new interpretative perspectives on the phenomenon of anti-Semitism, as well as aspects neglected in most of the reception of Adorno and Horkheimer’s work.

Humphreys and Forde conceptualize object representations as structural descriptions, without discussing the implications of structural description models. We argue that structural description models entail two major assumptions – a part-structure assumption and an invariance assumption. The invariance assumption is highly problematic because it contradicts a large body of findings which indicate that recognition performance depends on orientation and size. We will delineate relevant findings and outline an alternative conception.
