Classical spinning particles are interpreted in terms of an underlying geometric theory. They are described by trajectories on the Poincaré group. Upon quantization an eleven-dimensional Kaluza-Klein type theory is obtained which incorporates spin and isospin in a local SL(2, C)×U(1)×SU(2) gauge theory, unifying gravity and the pre-Higgs standard model. The relation to parametrized relativistic quantum theory is discussed.

Semiotics, the age-old investigation of signs, is still striving for acknowledgement as a scientific discipline. Though the ‘linguistic turn’ in the philosophical disciplines seemed to be followed by a ‘semiotic turn’ in many sciences during the 1970s, efforts were not crowned by great success. When seen from a certain distance, a definition of semiotics as a discipline can only be obtained from its history. Research into the sources of the human pre-occupation with signs, and with concepts or conceptions of signs, (...) is really desirable and even necessary when a field of considerable scientific interest at the brink of being awarded the rank of a discipline runs the risk of getting lost between the unificationism of the Morris-type and the elegance of pseudo-mathematical empty classificationism on the one side, and profitable exploitation of the sign's popularized design qualities on the other.

In cognitive science, long-term anticipation, such as when planning to do something next year, is typically seen as a form of ‘higher’ cognition, requiring a different account than the more basic activities that can be understood in terms of responsiveness to ‘affordances,’ i.e. to possibilities for action. Starting from architects that anticipate the possibility to make an architectural installation over the course of many months, in this paper we develop a process-based account of affordances that includes long-term anticipation within its (...) scope. We present a framework in which situations and their affordances unfold, and can be thought of as continuing a history of practices into a current situational activity. In this activity affordances invite skilled participants to act further. Via these invitations one situation develops into the other; an unfolding process that sets up the conditions for its own continuation. Central to our process account of affordances is the idea that engaged individuals can be responsive to the direction of the process to which their actions contribute. Anticipation, at any temporal scale, is then part and parcel of keeping attuned to the movement of the unfolding situations to which an individual contributes. We concretize our account by returning to the example of anticipation observed in architectural practice. This account of anticipation opens the door to considering a wide array of human activities traditionally characterized as ‘higher’ cognition in terms of engaging with affordances. (shrink)

To address the tension between demands for more transparent AI systems and the aim to develop and design robots with apparent agency for smooth and intuitive human-robot interaction (HRI), we present in this paper an argument for why explainability in HRI would benefit from being question-centered. First, we review how explainability has been discussed in AI and HRI respectively, to then present the challenge in HRI to accommodate the requirement of transparency while also keeping up the appearance of the robot (...) as a social agent. Based on the conceptualization of questions as information-seeking acts, our proposal for a question-centered approach to explainable HRI (xHRI) implies that to ensure transparency, robots shall provide explanations upon request in the form of questioning. We end this paper by laying out a preliminary taxonomy of xHRI-relevant questions that present the kinds of explanations a robot can or should be able to provide for successful and transparent HRI.

The "immeasurable lightness and fragility of the human fact." Jan Patočka and the Crisis of HumanismThe article addresses Jan Patočka’s writings in the immediate aftermath of the Second World War. The paper’s title – "The Immense Lightness and Fragility of the Human Fact" – is taken from a short, yet immensely crucial 1946 text of his that formulates a severe criticism of ideology/ideologies and eventually offers a profound questioning of humanist ideals. Accentuating his critique against the backdrop of Sartre's and (...) Heidegger's contemporaneous challenges to humanism, the paper argues that Patočka debunks a misconceived "cult of the human being" and ideologies of progress while insisting on the integrity of a human life in confrontation with its inherent weakness and fragility.

'Symbolizing existence' deals with the current rapidly happening deterritorialization of everything which was once regarded stable and binding. What we today regard as statistically encoded information is capable to explicate and index the entire realm of what can be expressed and represented through a cascade of geometrical, functional, or finally logified schemes. We are currently experiencing a rapid loss of grounding of that which we once considered binding in our cultural and intellectual history. How can we obtain an articulate, cultivate (...) way of thinking about instances that does not fall back into a schematic model Platonism (thereby falling behind Plato), and that does not remain enmeshed in an Aristotelian realization dynamics with a naturalism organized by original genus, kinds, and specific marks of distinction? The central phenomenon considered was the technological process of doping material: At the quantum level, a particle or its representation, the point, is no longer "that which has no parts" (Euclid).

Profit-oriented service sectors such as tourism, hospitality, and entertainment are increasingly looking at how professional service robots can be integrated into the workplace to perform socio-cognitive tasks that were previously reserved for humans. This is a work in which social and labor sciences recognize the principle role of emotions. However, the models and narratives of emotions that drive research, design, and deployment of service robots in human–robot interaction differ considerably from how emotions are framed in the sociology of labor and (...) feminist studies of service work. In this paper, we explore these tensions through the concepts of affective and emotional labor, and outline key insights these concepts offer for the design and evaluation of professional service robots. Taken together, an emphasis on interactionist approaches to emotions and on the demands of affective labor, leads us to argue that service employees are under-represented in existing studies in human–robot interaction. To address this, we outline how participatory design and value-sensitive design approaches can be applied as complimentary methodological frameworks that include service employees as vital stakeholders.

The future will tell whether or not the European Union is developing a political philosophy of its own. But the current trend indicates several interesting features structurally different, or asymmetric, to the experiences with the evolution of key notions of political philosophy in relation to the past experience with the development of statehood. The paper gives examples which call for deepened research and provides stimulating material for a new and innovative reflection on the process and substance of European integration, this (...) most unique feature of political history in the course of the 20th century.

After a short sketch of Lowe’s account of his four basic categories, I discuss his theory of formal ontological relations and how Lowe wants to account for dispositional predications. I argue that on the ontic level Lowe is a pan-categoricalist, while he is a language dualist and an exemplification dualist with regard to the dispositional/categorical distinction. I argue that Lowe does not present an adequate account of disposition. From an Aristotelian point of view, Lowe conflates dispositional predication with hôs epi (...) to poly statements about what is normally or mostly the case. (shrink)

This volume offer a manifold approach to a less evident and until now much neglected undercurrent in the work of Hannah Arendt., namely her ambiguous relation to the Judeo-Christian relligious heritage. Arendt's dissertation was dedicated to the concept of love in the works of Augustine, where she set her tone and developmed her frame for approaching theological matters. Her understanding of secularity might provide a model for the reconciliation of secularization and the persistence of religious belief in the contemporary world. (...) Thought Hannah Arendt wad certainly and outspokenly a secular thinker, her work also harbors ways of understanding secularization as the possibility of a new, maybe even messianic, attitude towards finite life and earthly reality. She famously depicts this attitude as "faith in and hope for the world". --Book cover. (shrink)

Imagination is often considered the pinnacle of representational cognition. Looking at the concrete details of imagining in context, this paper aims to contribute to the emerging literature that is challenging this representational view by offering a relational and radically situated alternative. On the basis of observing architects in the process of making an architectural art installation, we show how to consider imagination not as de-contextualized achievement by an individual but as an opening up to larger-scale “affordances,” i.e. the unfolding possibilities (...) for action. We show how the architects coordinate the enactment of multiple affordances across different timescales, from small-scale affordances of picking up a mobile phone to the large-scale affordance of making the installation that takes months to unfold. These affordances get co-determined as they are jointly enacted. It is within this determining process that imagination too finds its place. On our view it is the indeterminacy of multiple affordances unfolding in action simultaneously that can be experienced as imaginative. The indeterminate character of this coordinative process allows activities to widen and open up, letting new possibilities for action enter into them. (shrink)

This study delves into the significant ethical criteria in the context of global standards. It addresses the moral wrongdoings and adverse side effects associated with global value chains as discussed in the business ethics literature. The methodology involves theoretical application and synthesis. The study employs ethical principles from deontology, consequentialism, and political cosmopolitanism to establish normative criteria such as “injustice and harm to others” and “bad outcomes.” It further investigates how these criteria should influence consumers' decisions, actions, and responsibilities. These (...) criteria are then used to examine the moral wrongdoings and negative effects mentioned in global standards. The study explores how global standards implicitly express consumers' roles in governing global value chains. It scrutinizes consumers' actions and decisions by applying ethical frameworks to global standards. The study outlines consumers' individual and political responsibilities in achieving the goals of global standards. The research findings have implications for governments, consumers, and organizations in practicing shared responsibility. The aim of this research is to provide normative guidance for responsible actions. (shrink)

Radical empiricists at the turn of the twentieth century described organisms as experiencing the relations they maintain with their surroundings prior to any analytic separation from their environment. They notably avoided separating perception of the material environment from social life. This perspective on perceptual experience was to prove the inspiration for Gibson’s ecological approach to perceptual psychology. Gibson provided a theory of how the direct perception of the organism-environment relation is possible. Central to his account was the notion of a (...) medium for direct perception. However Gibson provided two mutually inconsistent accounts of the medium leading to problems for his radical empiricism. We develop an account of the medium that does justice to ecological psychology’s radical empiricist roots. To complement this account of the medium we detail a usage-based account of information. Together they allow us to propose a novel radical empiricist view of direct perception. We then return to the notion of medium and expand it to include sociomaterial practices. We show how direct perception happens in the midst of social life, and is made possible by an active achieving and maintaining of a pragmatic relation with the environment. (shrink)

This paper aims to provide a starting point for a non-representational approach to language. It will do so by undoing some of the reifying tendencies that are at the heart of the ontology of scientific psychology. Although non-representational theories are beginning to emerge, they remain committed to giving explanations in terms of ontological structures that are independent of human activity. If they maintain this commitment it is unlikely that they will displace representationalism in domains such as language. By following some (...) of Wittgenstein’s remarks on language, I explain the phenomenon of reification by carefully considering the formative, situational flow of language—thus without invoking representations. In this way, the paper sketches a direction of approach for a non-representational theory of language, undercutting the most important assumptions that justify an explanatory ontology devoid of human activity.

The smooth integration of the natural sciences with everyday lived experience is an important ambition of radical embodied cognitive science. In this paper we start from Koffka’s recommendation in his Principles of Gestalt Psychology that to realize this ambition psychology should be a “science of molar behaviour”. Molar behavior refers to the purposeful behaviour of the whole organism directed at an environment that is meaningfully structured for the animal. Koffka made a sharp distinction between the “behavioural environment” and the “geographical (...) environment”. We show how this distinction picks out the difference between the environment as perceived by an individual organism, and the shared publicly available environment. The ecological psychologist James Gibson was later critical of Koffka for inserting a private phenomenal reality in between animals and the shared environment. Gibson tried to make do with just the concept of affordances in his explanation of molar behaviour. We argue however that psychology as a science of molar behaviour will need to make appeal both to the concepts of shared publicly available affordances, and of the multiplicity of relevant affordances that invite an individual to act. A version of Koffka’s distinction between the two environments remains alive today in a distinction we have made between the field and landscape of affordances. Having distinguished the two environments, we go on to provide an account of how the two environments are related. Koffka suggested that the behavioural environment forms out of the causal interaction of the individual with a pre-existing, ready-made geographical environment. We argue that such an account of the relation between the two environments fails to do justice to the complex entanglement of the social with the material aspects of the geographical environment. To better account for this sociomaterial reality of the geographical environment, we propose a process-perspective on our distinction between the landscape and field of affordances. While the two environments can be conceptually distinguished, we argue they should also be viewed as standing in a relation of reciprocal and mutual dependence. (shrink)

Die Tradition der Metaphysik, auf die sich die Neuzeit bezieht verdankt ihre Physiognomie den systematischen Ansätzen, die den nach Aristoteles „zweiten“ Anfang der Metaphysik im 13. Jhd. Bestimmen. Der Zusammenhang, der die mittelalterliche Metaphysik mit der neuzeitlichen Metaphysik und Metaphysikkritik verbindet, ist jedoch immer noch zu wenig erforscht. Die vorliegende Untersuchung greift den einflußreichsten der mittelalterlichen Ansätze, den des Johannes Duns Scotus, auf und verfolgt seine Rezeption und Transformation über Francisco Suárez und Christian Wolff zu Immanuel Kant und Charles Sanders (...) Peirce. Nach Duns Scotus ist Metaphysik als Wissenschaft vom Seienden als Seienden nur dann möglich, wenn man sie nicht als Wissenschaft vom ersten ausgezeichneten Seienden, sondern als Wissenschaft vom ersterkannten Begriff des Seienden versteht. Da dieser Begriff nur im Rückgang auf die Voraussetzungen unserer kategorialen Prädikate erfaßt und nur im Durchgang durch seine modalen Bestimmungen entfaltet werden kann, faßt Scotus Metaphysik strikt als „Transzendentalwissenschaft“ (scientia transcendens) und ordnet ihr als Inhalt die formalmodale Bestimmung und Explikation der „ratio entis“ zu. Die Erkenntnis des unendlichen Seienden ist Teil dieser Explikation und nur als solche möglich. Die neuzeitliche Gestalt der Metaphysik, die sich auf der bisher meist herangezogenen Folie der Metaphysik des Thomas von Aquin als Traditionsbruch darstellt, erweist sich im Blick auf das Konzept des Scotus als Resultat einer kritischen Transformation.

Theorizing about perception is often motivated by a belief that without a way of ensuring that our perceptual experience correctly reflects the external world we cannot be sure that we perceive the world at all. Historically, coming up with a way of securing such epistemic contact has been a foundational issue in psychology. Recent ecological and enactive approaches challenge the requirement for perception to attain epistemic contact. This article aims to explicate this pragmatic starting point and the new direction of (...) inquiry that this opens up for psychology. It does so by detailing the development of James J. Gibson’s ecological psychology. Securing epistemic contact has been a leitmotiv in Gibson’s early work, but subsequent developments in Gibson’s works can teach us what it takes to adopt a pragmatic approach to psychology. We propose a reading of the developments in Gibson’s original works that shows that, since perception is a mode of acting, perception aims for pragmatic contact before allowing for epistemic contact. Amplifying these pragmatist lines of thought in Gibson’s works we end by considering situations where an individual is adapted to the intricacies of specific social practices. These situations show how pragmatic contact can also afford attaining epistemic contact. (shrink)

How we use our own victimhood and that of others has been changing in recent years. Today it may be used to decry an injustice of violence, to garner attention to our causes, to command a unique moral and ecclesial authority, or even to gain advantage over other groups.

Die Vertreibung jüdischer Psychoanalytiker aus NS-Deutschland ging damit einher, dass sie von ihren eigenen Kollegen aus der DPG gedrängt wurden. Dieser Bruch hat die Wiederanknüpfung echter Beziehungen zwischen beiden Gruppen nach dem Zusammenbruch des NS-Regimes und der deutschen Niederlage im Zweiten Weltkrieg erheblich belastet. Anhand erhaltener Korrespondenzen wird diese gestörte Nachkriegskommunikation rekonstruiert und auf ihre Langzeitfolgen geprüft.
