Dialogical logic is a game-theoretical approach to logic. Logic is studied with the help of certain games, which can be thought of as idealized argumentations. Two players, the Proponent, who puts forward the initial thesis and tries to defend it, and the Opponent, who tries to attack the Proponent’s thesis, alternately utter argumentative moves according to certain rules. For a long time the dialogical approach had been worked out only for classical and intuitionistic logic. The seven papers of this dissertation (...) show that this narrowness was uncalled for. The initial paper presents an overview and serves as an introduction to the other papers. Those papers are related by one central theme. As each of them presents dialogical formulations of a different non-classical logic, they show that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof. As such it is especially attractive to logical pluralists that reject the idea of “the single correct logic”. The collection contains treatments of free logic, modal logic, relevance logic, connexive logic, linear logic, and multi-valued logic. (shrink)

Second-person neuroscience offers a framework for the study of social emotions, such as embarrassment and pride. However, we propose that an enduring mental representation of oneself in relation to others without a continuous direct social interaction is possible. We call this state and will explain its impact on the neuroscience of social emotions.

There is an argument (first presented by Fitch), which tries to show by formal means that the anti-realistic thesis that every truth might possibly be known, is equivalent to the unacceptable thesis that every truth is actually known (at some time in the past, present or future). First, the argument is presented and some proposals for the solution of Fitch's Paradox are briefly discussed. Then, by using Wehmeier's modal logic with subjunctive marks (S5*), it is shown how the derivation can (...) be blocked if one respects adequately the distinction between the indicative and the subjunctive mood. Essentially, this proposal amounts to the one by Edgington which was formulated with the help of the actuality-operator. Finally it is shown how the criticisms by Williamson against Edgington can be answered by the formulation of a new conception of possible knowledge that \alpha (thereby \alpha being in the indicative mood and thus referring to the actual world). This conception is based on the concept of same de re knowledge in different possible worlds. (shrink)

Telegraphy, the distant ancestor of Internet and GSM (Global System for Mobile Communications), was invented by Samuel Morse in 1838. One year later, William Grove invented the fuel cell. Although numerous highly successful innovations stemming from telegraphy may be observed, the development of fuel cells has been insignificant, slow, and erratic and has not yet resulted in notable positive socioeconomic effects. By comparing the modern development of fuel cells and hydrogen technology, that is, a potential radical innovation in energy generation, (...) with some aspects related to the evolution of two highly successful radical innovations, Internet and GSM, the author focuses on the role of innovation regimes and policy in a sectorial system of innovations perspective. In the slow pace in fuel cells and hydrogen technology development, two factors seem to interact negatively: weak and fragmented innovation regimes in the energy sector and the current hegemony of market-oriented R&D policies.

Zusammenfassung: Aktuelle Debatten zu gesellschaftspolitischen Folgen der Corona-Pandemie zeigen, dass Intellektuelle wie Giorgio Agamben und Roberto Esposito den Begriff „Biopolitik“ ins Treffen führen, um Regierungsmaßnahmen zur Eindämmung des Virus zu analysieren. Seit Michel Foucaults Überlegungen zur Funktionsweise und Genealogie der Biopolitik birgt der Begriff jedoch eine gewisse Problematik: Aufgrund strukturell bedingter Mechanismen der Inklusion und Exklusion menschlichen Lebens gelingt es den biopolitischen Modellen nach Agamben und Esposito nicht – so die These –, ein zentrales Element des Politischen zu beschreiben. Unberücksichtigt (...) bleibt die Möglichkeit des Widerstands und der Kritik an Regierungsmaßnahmen; eine Möglichkeit, die gerade die Heterogenität politischer Ordnungsstrukturen anzeigt. Im Zuge der Analytik moderner Machttechniken verschiebt Foucault anders als Agamben und Esposito den Fokus von der Biopolitik hin zu einem umfassenderen Paradigma des „Regierens“, der Gouvernementalität. Infolgedessen lässt sich die Biopolitik als Regierungsweise thematisieren, mit der immer schon Formen widerständigen Handelns einhergehen. Um dieser Perspektive Rechnung zu tragen, argumentiert mein Beitrag mit Foucault gegen die primär strukturale Auffassung politischer Ordnungen nach Agamben und Esposito. (shrink)

This commentary reviews the basic physical principles underlying human single- and multi-joint arm movements. The potential role of the cerebellum in dealing with the physics of movement is discussed in the light of recent physiological findings and the theoretical model of cerebellar detection and generation of input and output sequences put forward by Braitenberg and colleagues.

The story of superheavy elements - those at the very end of the periodic table - is not well known outside the community of heavy-ion physicists and nuclear chemists. But it is a most interesting story which deserves to be known also to historians, philosophers, and sociologists of science and indeed to the general public. This is what the present work aims at. It tells the story or rather parts of the story, of how physicists and chemists created elements heavier (...) than uranium or searched for them in nature. And it does so with an emphasis on the frequent discovery and naming disputes concerning the synthesis of very heavy elements. Moreover, it calls attention to the criteria which scientists have adopted for what it means to have discovered a new element. In this branch of modern science it may be more appropriate to speak of creation instead of discovery. The work will be of interest to scientists as well as to scholars studying modern science from a meta-perspective. (shrink)

Special purpose service robots have already entered the market and their users’ homes. Also the idea of the general purpose service robot or personal robot companion is increasingly discussed and investigated. To probe human–robot interaction with a mobile robot in arbitrary domestic settings, we conducted a study in eight different homes. Based on previous results from laboratory studies we identified particular interaction situations which should be studied thoroughly in real home settings. Based upon the collected sensory data from the robot (...) we found that the different environments influenced the spatial management observable during our subjects’ interaction with the robot. We also validated empirically that the concept of spatial prompting can aid spatial management and communication, and assume this concept to be helpful for Human–Robot Interaction design. In this article we report on our exploratory field study and our findings regarding, in particular, the spatial management observed during show episodes and movement through narrow passages. Keywords: COGNIRON, Domestic Service Robotics, Robot Field Trial, Human Augmented Mapping, Human–Robot Interaction, Spatial Management, Spatial Prompting. (shrink)

By 1870, non-Euclidean geometry had been established as a mathematical research field but was yet to be considered relevant to the real space inhabited by stars and nebulae. It was of much less interest to physicists and astronomers than to mathematicians and philosophers. Although most astronomers took the age-old Euclidean geometry for granted, during the following decades a few of them such as K. F. Zöllner, S. Newcomb and K. Schwarzschild followed in the footsteps of the pioneer N. I. Lobachevsky (...) by seriously considering the possibility that cosmic space might be curved. From the H. Poincaré’s conventionalist perspective the discussion was meaningless since there was no way in which observations or other empirical data could determine the geometry of space. Poincaré’s view was shared by a few astronomers, but its impact on astronomy was limited. The paper examines the question as it was discussed prior to the advent of the general theory of relativity.

Artificial neural networks (ANNs) are new mathematical techniques which can be used for modelling real neural networks, but also for data categorisation and inference tasks in any empirical science. This means that they have a twofold interest for the philosopher. First, ANN theory could help us to understand the nature of mental phenomena such as perceiving, thinking, remembering, inferring, knowing, wanting and acting. Second, because ANNs are such powerful instruments for data classification and inference, their use also leads us into (...) the problems of induction and probability. Ever since David Hume expressed his famous doubts about induction, the principles of scientific inference have been a central concern for philosophers. (shrink)

In dominant discourses, migrants are mostly perceived as either victims or villains but rarely as political subjects and democratic constituents. Challenging this view, the aim of the article is to rethink democracy with respect to migration struggles. I argue that movements of migration are not only consistent with democracy but also provide a decisive impetus for actualizing democratic principles in the context of debates about the crisis of representation and post-democracy. Drawing on the work of Jacques Rancière, Étienne Balibar and (...) Ernesto Laclau and Chantal Mouffe, I develop a theory of radical democracy as practice, which, starting from the proposed notion of ‘democratic difference’, goes beyond the fixation on democratic regimes and focuses on contentious practices of enacting democratic principles. I articulate these theoretical concepts by analysing how refugees in Germany have managed to break out of a marginalized position and have challenged their denial of rights through a protest march.

We have studied ethical considerations of care among health professionals when treating and setting priorities for elderly patients in Norway. The views of medical doctors and nurses were analysed using qualitative methods. We conducted 21 in depth interviews and 3 focus group interviews in hospitals and general practices. Both doctors and nurses said they treated elderly patients different from younger patients, and often they were given lower priorities. Too little or too much treatment, in the sense of too many interventions (...) and too much drugs, combined with too little care and comfort, was admitted as a relatively frequent yet unwanted consequence of the way clinical priorities were set for elderly patients. This was explained in terms of elderly patients not tolerating the same treatment as younger patients, and questions were raised about the quality of life of many elderly patients after treatment. These explanations were frequently referred to as medically sound decision making. Other explanations had little to do with medically sound decisions. These often included deep frustration with executive guidelines and budget constraints. (shrink)

Summary Cosmology has always been different from other areas of the natural sciences. Although an observationally supported standard model of the universe emerged in the 1960s, more speculative models and conceptions continued to attract attention. During the last decade, ideas of multiple universes (the ‘multiverse’) based on anthropic reasoning have become very popular among cosmologists and theoretical physicists. This had led to a major debate within the scientific community of the epistemic standards of modern cosmology. Is the multiverse a scientific (...) hypothesis, or is it rather a philosophical speculation disguised as science? This paper offers a review of the recent and still ongoing controversy concerning the multiverse, emphasizing its foundational nature and relation to philosophical issues. It also compares the multiverse controversy to some earlier episodes in the history of twentieth-century cosmology when particular theories and approaches came under attack for betraying the ideals of proper science.

Background: There is little research comparing clinicians’ and managers’ views on priority settings in the healthcare services. During research on two different qualitative research projects on healthcare prioritisations, we found a striking difference on how hospital executive managers and clinical healthcare professionals talked about and understood prioritisations. Aim: The purpose of this study is to explore how healthcare professionals in mental healthcare and somatic medicine prioritise their care, to compare different ways of setting priorities among managers and clinicians and to (...) explore how moral dilemmas are balanced and reconciled. Research design and participants: We conducted qualitative observations, interviews and focus groups with medical doctors, nurses and other clinical members of the interdisciplinary team in both somatic medical and mental health wards in hospitals in Norway. The interviews were recorded and transcribed verbatim. Ethical considerations: Basic ethical principles for research ethics were followed. The respondents signed an informed consent for participation. They were assured anonymity and confidentiality. The studies were approved by relevant ethics committees in line with the Helsinki Convention. Findings: Our findings showed a widening gap between the views of clinicians on one hand and managers on the other. Clinicians experienced a threat to their autonomy, to their professional ideals and to their desire to perform their job in a professional way. Prioritisations were a cause of constant concern and problematic decisions. Even though several managers understood and empathised with the clinicians, the ideals of patient flow and keeping budgets balanced were perceived as more important. Discussion: We discuss our findings in light of the moral challenges of patient-centred individual healthcare versus demands of distributive justice from healthcare management. Conclusion: The clinicians’ ideals of autonomy and good medical and nursing care for the individual patients were perceived as endangered. (shrink)

In this essay I intend to flesh out and discuss what I consider to be the groundbreaking contribution by the German historian and theorist of history Reinhart Koselleck to postwar historiography: his theory of historical times. I begin by discussing the view, so prominent in the Anglophone context, that Koselleck's idea of the plurality of historical times can be grasped only in terms of a plurality of historical periods in chronological succession, and hence, that Koselleck's theory of historical times is (...) in reality a theory of periodization. Against this interpretation, to be found in works by Kathleen Davis, Peter Osborne, and Lynn Hunt, among others, I will argue that not only is Koselleck's theory of historical times, or, with a more phenomenlogical turn of phrase, his theory of multiple temporalities, not a theory of periodization, it is, furthermore, a theory developed to defy periodization. Hence, at the core of Koselleck's work is the attempt to replace the idea of linear, homogeneous time with a more complex, heterogeneous, and multilayered notion of temporality. In this essay I will demonstrate how this shift is achieved by means of three dichotomies: between natural and historical, extralinguistic and intralinguistic, and diachronic and synchronic time.

Kant is generally conceived to have offered little attention to the fact that we experience the world in and through our bodies. This book argues that this standard image of the great German philosopher is radically wrong. Not only does Kant - throughout his career and in works published before and after the Critique of pure reason - reflect constantly upon the fact that human life is embodied, but the Critique of pure reason itself may be read as a critical (...) reflection aimed at exploring some significant philosophical implications of this fact. Bringing this aspect of Kant's philosophy into focus is important, not only because it sheds new light on our understanding of Kant's work, but also because it is relevant to contemporary discussions in philosophy about embodiment, learning and practice. By taking his philosophy of embodiment into account, the author makes Kant stand out as a true contemporary in new and unexpected ways. (shrink)

This volume offers a critical analysis and illustration of the challenges and promises of ‘stateless’ law thought, pedagogy and approaches to governance - that is, understanding and conceptualizing law in a post-national condition. Confronting the ‘transnational challenge’ posed to the traditional theoretical and institutional structures that underlie the teaching and study of law in the university, the book brings new insight to the ongoing and crucial conversation about the future shape of legal scholarship, education and practice that is emblematic of (...) the early twenty-first century.

A mobile service robot performing a task for its user might not be able to accomplish its mission without help from other people present in the shared environment. In previous research, collaborative control has been studied as an interactive mode of operation with a robot, compensating for its limitations in autonomy. However, few studies of robots requesting assistance by detecting potential collaborators, directing its attention to them, addressing them, and finally obtaining help from them, have previously been performed in real-world (...) use contexts. This study focuses on a fetch-and-carry robot, Cero, which has been designed to operate in an office environment as an aid for motion-impaired users. During its missions, the robot sometimes needs help with loading or unloading an object. The main question for the study was: under what conditions are people willing to help when requested to do so by the robot? We were particularly interested in bystanders, i.e. people who happened to be in the environment but who did not “have any official business” with the robot. To answer these questions and to provide a better understanding of human–robot help-seeking situations, we conducted an experimental study in which subjects who had not encountered our service robot before were requested to assist it with a task. The results of the study confirm that bystanders can to some degree be expected to help in robot missions, but that their willingness to help the robot depends on the situation and state of occupation that people are in when requested to interact with and assist the robot.

Le but de cet article est de montrer comment les logiques dites multivalentes peuvent être formulées dans le cadre de la logique dialogique. Pour formuler les règles de particule pour ces logiques on introduit l’idée de différents modes d’assertion. En donnant ensuite les règles de particule et les règles structurelles appropriées, on peut reconstruire dialogiquement les systèmes standards de logiques multivalentes. Cela est fait explicitement pour la logique `a trois valeurs de Łukasiewicz (L3c). En remplaçant la règle structurelle classique par (...) sa contrepartie intuitionniste on obtient des versions intuitionnistes de systèmes multivalents (par exemple L3i). Les systèmes dialogiques multivalents L3c et L3i sont illustrés par quelques exemples et pour conclure on formule les tableaux stratégiques correspondants. (shrink)

Keine ausführliche Beschreibung für "Natur und Technik – Theorie und Strategie" verfügbar.

Trust between a patient and a medical doctor is normally both justified and taken for granted, but sometimes it may need to be negotiated. In this paper I will present how trust can be interpreted as both an explicit and implicit phenomenon, drawing on literature from the social sciences and philosophy. The distinction between explicit and implicit interpretations of trust will be used to address problems that may arise in clinical consultations. Negotiating trust in any way very easily brings distrust (...) into a situation, but sometimes this can be helpful for building a more functional patient-doctor relationship. (shrink)

This article examines what comes to pass when philosophical practitioners start working in the institutional environment of a hospital, with its unique norms and culture through the experience of three philosophical practitioners in Norway. It finds that that a notable characteristic of these practitioners is their effort to avoid taking on the traditional helper role, which they perceive that other hospital professions are representing. Their ideal is to approach “life here and now” with openness, acceptance, curiosity, and wondering, while simultaneously (...) supporting a serious, playful creativity in the search for new perspectives when relevant. For the patients, this offers a space where they can rediscover themselves as whole individuals, rather than rather only beings in need of help. The article concludes that philosophical practitioners have the potential to play a significant role within hospitals. (shrink)
