Objectives:Social isolation is increasing in aging societies and several studies have shown a relation with worse cognition in old age. However, less is known about the association in the oldest-old (85+); the group that is at highest risk for both social isolation and dementia. Methods:Analyses were based on follow-up 5 to 9 of the longitudinal German study on aging, cognition, and dementia in primary care patients (AgeCoDe) and the study on needs, health service use, costs, and health-related quality of life (...) in a large sample of oldest-old primary care patients (AgeQualiDe), a multi-center population-based prospective cohort study. Measurements included the Lubben Social Network Scale (LSNS-6), with a score below 12 indicating social isolation, as well as the Mini-Mental Status Examination (MMSE) as an indicator of cognitive function. Results:Dementia-free study participants (n = 942) were M = 86.4 (SD = 3.0) years old at observation onset, 68.2% were women. One third (32.3%) of them were socially isolated. Adjusted linear hybrid mixed effects models revealed significantly lower cognitive function in individuals with smaller social networks (β = 0.5, 95% CI = 0.3-0.7, p <.001). Moreover, changes in an individual's social network size were significantly associated with cognitive changes over time (β = 0.2, 95% CI = 0.1-0.4, p =.003), indicating worse cognitive function with shrinking social networks. Conclusion:Social isolation is highly prevalent among oldest-old individuals, being a risk factor for decreases in cognitive function. Consequently, it is important to maintain a socially active lifestyle into very old age. Likewise, this calls for effective ways to prevent social isolation. (shrink)

Religiöse Vielfalt mitsamt ihren destruktiven und bereichernden Elementen gehört weltweit mehr denn je zur Signatur der Lebenswelt gegenwärtiger Gesellschaften. Interreligiöse Kommunikation ist daher ein dialogischer Imperativ, von dem die friedliche Koexistenz religiöser Gemeinschaften in der jeweiligen Gesellschaft oder ganzer benachbarter Kulturen abhängt. Im Zentrum des Bandes steht die - im Zusammenspiel theologischer, religionswissenschaftlicher und -philosophischer, soziologischer sowie erziehungs- und medienwissenschaftlicher Perspektiven zu führende - Auseinandersetzung mit der höchst aktuellen Frage nach den Bedingungen und Grenzen des konstruktiven Umgangs mit religiöser Pluralität (...) und Differenz. Die Beiträge bieten unterschiedliche theoretische Zugänge sowie historische, religionswissenschaftliche und pädagogische Fallbeispiele. Sie sollen helfen, die Bedingungen und Potentiale einer kommunikativen Praxis zu diskutieren, die von der berechtigten Vielstimmigkeit einander widerstreitender Wahrheits- und Geltungsansprüche ausgeht und dazu befähigt, religiöse Differenz anzuerkennen und ihr mit Achtung zu begegnen, ohne den eigenen Standpunkt im Interesse eines rein konsensorientierten Dialogs zu verschweigen.

This study aims to describe social network and social participation and to assess associations with depressive symptoms in older persons with increased risk for dementia in Germany. We conducted a cross-sectional observational study in primary care patients (aged 60-77) as part of a multicenter cluster-randomized controlled trial (AgeWell.de). We present descriptive and multivariate analyses for social networks (Lubben Social Network Scale and subscales) and social participation (item list of social activities) and analyze associations of these variables with depressive symptoms (Geriatric (...) Depression Scale). Of 1030 included patients, 17.2% were at risk for social isolation (Lubben Social Network Scale < 12). Looking at the subscales, a reduced non-family network was found almost twice as often as a reduced family network. Patients with depressive symptoms had significantly smaller social networks than patients without depression (p < 0.001). They rather engaged in social activities of low involvement level or no weekly social activity at all (p < 0.001). The study shows associations of depressive symptoms with a decreased social network and less social participation in elderly participants. Sufficient non-family contacts and weekly social activities seem to play an important role in mental health and should be encouraged in elderly primary care patients. (shrink)

La philosophie peut-elle changer le monde? À en écouter Wittgenstein, la réponse est non. La philosophie laisse le monde tel qu’il est. Sa tâche consiste en la résolution des « pseudo-problèmes » qu’elle s’est elle-même posée. Pour Hans Jonas, au contraire, cette manière de philosopher est vaine. Oui, la philosophie peut et doit changer le monde, elle doit même s’emparer des problèmes du moment. Après être devenu un érudit du gnosticisme, Jonas comprend les limites de sa tour d’ivoire et rép...

Could a sufficiently detailed computer simulation of consciousness replicate consciousness? In other words, is performing the right computations sufficient for artificial consciousness? Or will there remain a difference between simulating and being a conscious system, because the right computations must be implemented in the right way? From the perspective of Karl Friston's free energy principle, self-organising systems (such as living organisms) share a set of properties that could be realised in artificial systems, but are not instantiated by computers with a (...) classical (von Neumann) architecture. I argue that at least one of these properties, viz. a certain kind of causal flow, can be used to draw a distinction between systems that merely simulate, and those that actually replicate consciousness. Since this property is instantiated by all systems that conform to the free energy principle (not just conscious beings), the account on offer here can be extended to draw a distinction between simulating and being a certain type of system, more generally. In particular, this may inform meta-ethical accounts of artificial moral status and artificial moral agency. (shrink)

An interdisciplinary account of phenomenal unity, investigating how experiential wholes can be characterized and how such characterizations can be analyzed computationally. How can we account for phenomenal unity? That is, how can we characterize and explain our experience of objects and groups of objects, bodily experiences, successions of events, and the attentional structure of consciousness as wholes? In this book, Wanja Wiese develops an interdisciplinary account of phenomenal unity, investigating how experiential wholes can be characterized and how such characterization (...) can be analyzed conceptually as well as computationally. Wiese first addresses how the unity of consciousness can be characterized phenomenologically, discussing what it is like to experience wholes and what is the experiential contribution of phenomenal unity. Considering the associated conceptual and empirical issues, he draws connections to phenomenological accounts and research on Gestalt theory. The results show how the attentional structure of experience, the experience of temporal flow, and different types of experiential wholes contribute to our sense of phenomenal unity. Moreover, characterizing phenomenal unity in terms of the existence of a single global phenomenal state is neither necessary nor sufficient to adequately address the problem of phenomenal unity. Wiese then suggests that the concepts and ideas of predictive processing can be used to analyze phenomenal unity computationally. The result is both a conceptual framework and an interdisciplinary account: the regularity account of phenomenal unity. According to this account, experienced wholes correspond to a hierarchy of connecting regularities. The brain tracks these regularities by hierarchical prediction error minimization, which approximates hierarchical Bayesian inference. (shrink)

Now available in English for the first time, The Visibility of the Image explores the development of an influential aesthetic tradition through the work of six figures. Analysing their contribution to the progress of formal aesthetics, from its origins in Germany in the 1880s to semiotic interpretations in America a century later, the six chapters cover: Robert Zimmermann (1824-1898), the first to separate aesthetics and metaphysics and approach aesthetics along the lines of formal logic, providing a purely syntactic way of (...) using signs, regardless of objective content; Alois Riegl (1858-1905), who went on to further develop aesthetics on the model of formal logic, creating a theory of style in response to Zimmermann's call for an aesthetics oriented toward formal logic; Heinrich Wölfflin (1864-1945), who represents a step toward an understanding of consciousness by using pictures as cognitive tools; Konrad Fiedler (1841-1895), the Saxon philosopher who considered the possibility that some kinds of images are made and viewed not for what they show, but for their visibility's sake alone; Maurice Merleau-Ponty (1908-1961), responsible for taking up the connections between the problems of reducing the range of potential meanings and contexts of a given image down to just the picture surface; Charles William Morris (1901-1979), who set out to establish whether a picture with no objective reference, such as an abstract painting, still counts as a sign, and if so, in what sense. Bringing these thinkers together and interlinking their ideas, Lambert Wiesing presents an engaging history of formal aesthetics, while reconstructing the philosophical foundations for the appearance of new image forms in the 20th century, including the video-clip, abstract collage, digital simulation and virtual reality. Using this original approach, The Visibility of the Image introduces the rise of modern image theory and provides a valuable account of our engagement with pictures in the 21st century. (shrink)

Zusammenfassung Die Forschungs- und Regulierungsebene bei datenintensiver Forschung in der Medizin liegen auseinander. Ein heterogenes Feld aus regulierenden Institutionen mit regional ungleichen Regelungen, sowohl hinsichtlich der Dichte als auch der Restriktivität von Regelungen, steht einer globalen Entwicklung der Technologien entgegen. Trotz oder gerade wegen mangelnder global-gültiger Regulierungen können auch unverbindliche oder nur bedingt verbindliche normative Vorgaben der Orientierung dienen. Doch wie soll eine solche normative Regulierung angesichts datenintensiver Forschung in der Medizin ausgestaltet werden und woran soll sie sich orientieren? Die (...) Frage, wie konkret und detailliert man eine solche Forschung regulieren sollte, lässt sich nur im Einzelfall für bestimmte Situationen und Institutionen beantworten. Ob dabei neue Normen oder Gewichtungen von Normen vorgenommen werden sollen, oder ob die Normen und deren Gewichtung weiterhin bestehen bleiben sollen, lässt sich nur mit Verweis auf starke normative Argumente beantworten. An zwingenden Argumenten für neue Normen angesichts der datenintensiven medizinischen Forschung mangelt es bisher. Dennoch ist eine Umsetzungsarbeit von Normen, egal ob neue oder alte, und deren Anwendung auf eine neue Methode oder Technologie allemal zu erbringen. Es bedarf daher – wie schon bisher – beider: sowohl etablierter und transparent kommunizierter Normen als auch des unabhängigen Urteils zur Anwendung dieser Normen. Angesichts der besonderen Eignung für diese Aufgabe sollten auch weiterhin Ethik-Kommissionen als prozedurale Instanz bei der Bewilligung von datenintensiver Forschung in der Medizin gefordert und befähigt werden, die als unabhängige Institution ein Urteil im Einzelfall anhand vorgegebener Normen fällen. Nichtsdestotrotz können sich die veränderten Praktiken datenintensiver Forschungsprojekte auch in neuen Anforderungen an Ethik-Kommissionen niederschlagen, denen mit Reformen der Arbeitsweise begegnet werden sollte.

Lambert Wiesing's The Philosophy of Perception challenges current theories of perception. Instead of attempting to understand how a subject perceives the world, Wiesing starts by taking perception to be real. He then asks what this reality means for a subject. In his original approach, the question of how human perception is possible is displaced by questions about what perception obliges us to be and do. He argues that perception requires us to be embodied, to be visible, and to continually participate (...) in the public and physical world we perceive. Only in looking at images, he proposes, can we achieve something like a break in participation, a temporary respite from this, one of perception's relentless demands. Wiesing's methods chart a markedly new path in contemporary perception theory. In addition to identifying common ground among diverse philosophical positions, he identifies how his own, phenomenological approach differs from those of many other philosophers, past and present. As part of the argument, he provides a succinct but comprehensive survey of the philosophy of images His original critical exposition presents scholars of phenomenology, perception and aesthetics with a new, important understanding of the old phenomenon, the human being in the world.

Legitimation und Musiktheater im Diskurs : politische, wirtschaftliche und ästhetische Narrative -- Material und Methode -- Legitimationsstrategien im Diskurs um das Musiktheater -- Schlussbetrachtung.

Whilst the topic of representations is one of the key topics in philosophy of mind, it has only occasionally been noted that representations and representational features may be gradual. Apart from vague allusions, little has been said on what representational gradation amounts to and why it could be explanatorily useful. The aim of this paper is to provide a novel take on gradation of representational features within the neuroscientific framework of predictive processing. More specifically, we provide a gradual account of (...) two features of structural representations: structural similarity and decoupling. We argue that structural similarity can be analysed in terms of two dimensions: number of preserved relations and state space granularity. Both dimensions can take on different values and hence render structural similarity gradual. We further argue that decoupling is gradual in two ways. First, we show that different brain areas are involved in decoupled cognitive processes to a greater or lesser degree depending on the cause (internal or external) of their activity. Second, and more importantly, we show that the degree of decoupling can be further regulated in some brain areas through precision weighting of prediction error. We lastly argue that gradation of decoupling (via precision weighting) and gradation of structural similarity (via state space granularity) are conducive to behavioural success. (shrink)

Kairos has been a key concept in medicine for millennia and is frequently understood as “the right time” in relation to treatment. In this study we scrutinize kairos in the context of diagnostics. This has become highly topical as technological developments have caused diagnostics to be performed ever earlier in the disease development. Detecting risk factors, precursors, and predictors of disease (in biomarkers, pre-disease, and pre-pre-disease) has resulted in too early diagnoses, i.e., overdiagnoses. Nonetheless, despite vast advances in science and (...) technology, diagnoses also come too late. Accordingly, timing diagnostics right is crucial. In this article we start with giving a brief overview of the etymology and general use of the concepts of kairos and diagnosis. Then we delimit kairos in diagnostics by analysing “too early” and “too late” diagnosis and by scrutinizing various phases of diagnostics. This leads us to define kairos of diagnostics as the time when there is potential for sufficient information for making a diagnosis that is most helpful for the person. It allows us to conclude that kairos is as important in diagnostics as in therapeutics. (shrink)

The goal of this short chapter, aimed at philosophers, is to provide an overview and brief explanation of some central concepts involved in predictive processing (PP). Even those who consider themselves experts on the topic may find it helpful to see how the central terms are used in this collection. To keep things simple, we will first informally define a set of features important to predictive processing, supplemented by some short explanations and an alphabetic glossary. -/- The features described here (...) are not shared in all PP accounts. Some may not be necessary for an individual model; others may be contested. Indeed, not even all authors of this collection will accept all of them. To make this transparent, we have encouraged contributors to indicate briefly which of the features are necessary to support the arguments they provide, and which (if any) are incompatible with their account. For the sake of clarity, we provide the complete list here, very roughly ordered by how central we take them to be for “Vanilla PP” (i.e., a formulation of predictive processing that will probably be accepted by most researchers working on this topic). More detailed explanations will be given below. Note that these features do not specify individually necessary and jointly sufficient conditions for the application of the concept of “predictive processing”. All we currently have is a semantic cluster, with perhaps some overlapping sets of jointly sufficient criteria. The framework is still developing, and it is difficult, maybe impossible, to provide theory-neutral explanations of all PP ideas without already introducing strong background assumptions. (shrink)

These collected studies on the philosophy of the image offer the fundamental insight that images alone make the artificial presence of things possible. Images present things as exclusively visible, released from the laws of physics. Taking this idea as his point of departure, Wiesing provides an overview of the fundamental positions in contemporary image studies. He describes the use of images as signs from a phenomenological perspective, reconstructs Plato's concept of mimesis by way of the canon of images it presupposes, (...) and demonstrates the special relevance of extreme types of images— virtual reality, desktop windows, or abstract photography—for the philosophical labor of the concept of the image.

This essay addresses Cartesian duality and how its implicit dialectic might be repaired using physics and information theory. Our agenda is to describe a key distinction in the physical sciences that may provide a foundation for the distinction between mind and matter, and between sentient and intentional systems. From this perspective, it becomes tenable to talk about the physics of sentience and ‘forces’ that underwrite our beliefs (in the sense of probability distributions represented by our internal states), which may ground (...) our mental states and consciousness. We will refer to this view as Markovian monism, which entails two claims: (1) fundamentally, there is only one type of thing and only one type of irreducible property (hence monism). (2) All systems possessing a Markov blanket have properties that are relevant for understanding the mind and consciousness: if such systems have mental properties, then they have them partly by virtue of possessing a Markov blanket (hence Markovian). Markovian monism rests upon the information geometry of random dynamic systems. In brief, the information geometry induced in any system—whose internal states can be distinguished from external states—must acquire a dual aspect. This dual aspect concerns the (intrinsic) information geometry of the probabilistic evolution of internal states and a separate (extrinsic) information geometry of probabilistic beliefs about external states that are parameterised by internal states. We call these intrinsic (i.e., mechanical, or state-based) and extrinsic (i.e., Markovian, or belief-based) information geometries, respectively. Although these mathematical notions may sound complicated, they are fairly straightforward to handle, and may offer a means through which to frame the origins of consciousness. (shrink)

In Germany — as probably worldwide — in vitro fertilization has provoked disapproval, fears, and dread, but it also raises hope and gives feelings of pride and satisfaction in a new scientific achievement. Critics look for convincing argu- ments that could ban IVF completely or at least restrict it considerably. Some of the most important arguments are outlined below.The main aspect of IVF that was new to society was that conception could take place outside the female body. Although this fact (...) has made a deep impression on us, no ethical relevance has been attributed to it. One must look further for arguments against IVF. (shrink)

The article aims to illuminate the recent debate in Germany about the legitimacy of circumcision for religious reasons. The aim is both to evaluate the new German law allowing religious circumcision, and to outline the resulting conflict between the surrounding ethical and legal issues. We first elucidate the diversity of legal and medical views on religious circumcision in Germany. Next we examine to what extent invasive and irreversible physical interventions on infant boys unable to given their consent should be carried (...) out for non-medical reasons. To this end, the potential benefits and harms of circumcision for non-medical reasons are compared. We argue that circumcision does not provide any benefits for the ‘child as a child’ and poses only risks to boys. We then set out to clarify and analyse political justifications of the new circumcision law. We demonstrate through this analysis how the circumcision debate in Germany has been transformed from a legal and ethical problem into a political issue, due at least in part to Germany's unique historical context. Although such a particular political sensibility is entirely comprehensible, it raises particular problems when it comes to framing and responding to medical ethical issues – as in the case of religious circumcision.

Gaze following occurs automatically in social interactions, but the degree to which gaze is followed depends on whether an agent is perceived to have a mind, making its behavior socially more relevant for the interaction. Mind perception also modulates the attitudes we have towards others, and deter-mines the degree of empathy, prosociality and morality invested in social interactions. Seeing mind in others is not exclusive to human agents, but mind can also be ascribed to nonhuman agents like robots, as long (...) as their appearance and/or behavior allows them to be perceived as intentional beings. Previous studies have shown that human appearance and reliable behavior induce mind perception to robot agents, and positively affect attitudes and performance in human-robot interaction. What has not been investigated so far is whether different triggers of mind perception have an independent or interactive effect on attitudes and performance in human-robot interaction. We examine this question by manipulating agent appearance (human vs. robot) and behavior (reliable vs. random) within the same paradigm and examine how congruent (human/reliable vs. robot/random) versus incongruent (human/random vs. robot/reliable) combinations of these triggers affect performance (i.e., gaze fol-lowing) and attitudes (i.e., agent ratings) in human-robot interaction. The results show that both ap-pearance and behavior affect human-robot interaction but that the two triggers seem to operate in iso-lation, with appearance more strongly impacting attitudes, and behavior more strongly affecting per-formance. The implications of these findings for human-robot interaction are discussed. (shrink)

The World Medical Association has announced that a new revision process of the Declaration of Helsinki has been started. This article will identify the criticisms that have been made in the bioethics literature, particularly since the last revision. In addition, criticisms are discussed that were made in the literature even before the last revision and have not fallen silent. The plausibility of the recommendation for a change in the Declaration of Helsinki is examined.

In March 2020, the rapid increase in severe COVID‐19 cases overwhelmed the healthcare systems in several European countries. The capacities for artificial ventilation in intensive care units were too scarce to care for patients with acute respiratory disorder connected to the disease. Several professional associations published COVID‐19 triage recommendations in an extremely short time: in 21 days between March 6 and March 27. In this article, we compare recommendations from five European countries, which combine medical and ethical reflections on this (...) situation in some detail. Our aim is to provide a detailed overview on the ethical elements of the recommendations, the differences between them and their coherence. In more general terms we want to identify shortcomings in regard to a common European response to the current situation. (shrink)

In this study, we investigate the three-dot sign as a discourse marker (DM) with textual, subjective and intersubjective discourse functions. As a graphical marker that is used across languages, the three-dot sign is especially suitable for comparative studies and dynamics in language contact. Our corpus study targeting instant messages of different languages (English, German, Greek, Russian, Turkish) and speaker groups (monolinguals and bilingual heritage speakers) suggests that graphical DMs are prone to cross-linguistic influence. This depends on the specific contact situation (...) and does not seem to be a general effect of bilingualism. The societal status of a language might further influence the use of such markers in digital informal writing. Language-specific developments that relate to emerging functions indicate that functional versatility promotes frequent use of (graphical) DMs. (shrink)

Should models of consciousness be detailed _mechanistic_ models of particular types of systems, or should they be _minimal_ models that abstract away from the underlying mechanistic details and provide generalisations? Detailed mechanistic models may afford a complete and precise account of consciousness in human beings and other, physiologically similar mammals. But they do not provide a good model of consciousness in other animals, such as non-vertebrates, let alone artificial systems. Minimal models can be applicable to a wide range of different (...) conscious systems. But do they provide genuine explanations that are autonomous from explanations by detailed mechanistic models? This paper provides a taxonomy of minimal models and measures of consciousness, clarifies their relation to detailed mechanistic models, and highlights benefits of different minimalist approaches to consciousness.

A weak version of the life-mind continuity thesis entails that every living system also has a basic mind (with a non-representational form of intentionality). The strong version entails that the same concepts that are sufficient to explain basic minds (with non-representational states) are also central to understanding non-basic minds (with representational states). We argue that recent work on the free energy principle supports the following claims with respect to the life-mind continuity thesis: (i) there is a strong continuity between life (...) and mind; (ii) all living systems can be described as if they had representational states; (iii) the ’as-if representationality’ entailed by the free energy principle is central to understanding both basic forms of intentionality and intentionality in non-basic minds. In addition to this, we argue that the free energy principle also renders realism about computation and representation compatible with a strong life-mind continuity thesis (although the free energy principle does not entail computational and representational realism). In particular, we show how representationality proper can be grounded in ’as-if representationality’. (shrink)
