Two centuries ago Bernard Bolzano published his Contributions to a more well-founded presentation of mathematics which Goethe praised as “an opusculum of very high value”. Bolzano still seems to accept the traditional principle that that intension and extension of a concept stand in an inverse relation . In particular he claims that the concept of a genus proximum is always a component of the concept of the species which are subordinated to it. However, this does not harmonize with his simultaneous (...) assumption that there are simple species-concepts. In section 1 of this paper I shall try to bring to light this tension in Bolzanos Contributions. In section 2 I shall try to reconstruct Bolzano ’s arguments to the effect that the properties an object must have if it is to fall under a certain concept are not always components of that concept. In section 3 I shall try to reconstructs his arguments against the Canon in his Theory of Science .In seinen vor zwei Jahrhunderten erschienenen Beyträgen zu einer begründeteren Darstellung der Mathematik, die Goethe als „ein Werkchen von besonderem Werte“ pries, scheint Bernard Bolzano den traditionellen Lehrsatz der Reziprozität noch zu akzeptieren, demzufolge Inhalt und Umfang eines Begriffs in inversem Verhältnis stehen. Insbesondere akzeptiert er die traditionelle These, dass der Begriff eines genus proximum immer ein Bestandteil der Begriffe der Spezies dieses Genus ist. Diese Annahme schient aber im Gegensatz zu seiner gleichzeitigen Akzeptanz der These zu stehen, dass es einfache Spezies-Begriffe gibt. Im Paragraphen 1 bespreche ich diese Frage. Im Paragraphen 2 versuche ich, einige der Argumente zu rekonstruieren, die Bolzano in seiner Wissenschaftslehre zur Widerlegung der These verwendet, dass die Begriffe der Beschaffenheiten, die ein Gegenstand haben muss, um unter einen bestimmten Begriff zu fallen, immer Teile dieses Begriffs sind. Im Paragraphen 3 präsentiere ich die wichtigsten Argumente Bolzanos, die in der Wissenschaftslehre dafür verwendet werden, um den Kanon Allgemeingültigkeit abzusprechen. (shrink)

Quantification is particularly seductive in times of global uncertainty. Not surprisingly, numbers, indicators, categorizations, and comparisons are central to governmental and popular response to the COVID-19 pandemic. This essay draws insights from critical data studies, sociology of quantification and decolonial thinking, with occasional excursion into the biomedical domain, to investigate the role and social consequences of counting broadly defined as a way of knowing about the virus. It takes a critical look at two domains of human activity that play a (...) central role in the fight against the virus outbreak, namely medical sciences and technological innovation. It analyzes their efforts to craft solutions for their user base and explores the unwanted social costs of these operations. The essay argues that the over-reliance of biomedical research on “whiteness” for lab testing and the techno-solutionism of the consumer infrastructure devised to curb the social costs of the pandemic are rooted in a distorted idea of a “standard human” based on a partial and exclusive vision of society and its components, which tends to overlook alterity and inequality. It contends that to design our way out of the pandemic, we ought to make space for distinct ways of being and knowing, acknowledging plurality and thinking in terms of social relations, alterity, and interdependence.

At a time when they had largely fallen into disrepute Bolzano reactivated the distinctions between ‚clear‘ and ‚obscure‘, ‚distinct‘ and ‚confused‘ ideas. In the central sections of this paper I offer a critical reconstruction of the explanations of these pairs of opposita which are to be found in vol. III of Bolzano's monumental Wissenschaftslehre . I then provide a detailed account of its Leibnizian counterparts that were well-known to the ‚Bohemian Leibniz‘, and finally I evaluate Bolzano's criticism thereof.

What are the main learning difficulties or advantages encountered by students with learning disabilities within e-environments? As a result of the Covid-19 emergency, e-learning is being increasingly used to support students’ learning processes. A number of countries closed their schools altogether, so face-to-face lessons were and have been replaced by distance lessons. A search of current literature via Scopus, Eric and Google Scholar electronic databases was conducted according to Prisma Guidelines. Other sources of literature were also considered, starting from the (...) references in the full text of the articles consulted. We used the following search keywords: “LDs” combined with the “AND/OR” Boolean operator and “e-learning platforms,” “well-being,” “psychological factors,” “emotional distress,” and “self-regulation.” One body of literature highlights the lack of inclusive accessibility standards and a lack of attention to specific tools for addressing LDs, which causes students to develop high levels of stress/anxiety and emotional distress, in addition to low levels of well-being, self-esteem and self-efficacy. Another area of literature looks at how students can develop high levels of self-regulation and emotional awareness, as well as high levels of inclusion. Results are discussed in terms of the promotion of e-learning that focuses on the psychological well-being of students and teachers use of technological tools. (shrink)

Stefania Tutino shows that post-Reformation Catholic culture was a rich laboratory for our current moral and hermeneutical anxieties.

The chemist and philosopher Michael Polanyi was one of the first twentieth-century scientists to propose a program to resolve the internal conflict of the modern Enlightenment: scientific detachment and moral nihilism with humanist values. Stefania Jha’s intellectual biography places Polanyi in the context of his time and culture, analyzes his key philosophical ideas, and explicates the application—and at times misappropriation—of his work. Polanyi’s method was not laid out in his published works, and his vocabulary tends to make his writings (...) difficult to understand. By exposing the structure of his theory of tacit knowing, and by tracing the growth of his thinking, Jha shows how the various elements of his thought are integrated. Through examination of his philosophical roots in Kant and the complexity of his evolving thought, she counteracts the popular notion that Polanyi’s philosophy stands apart from the western philosophic tradition. Jha’s deep analysis makes Polanyi’s shift of focus from science to philosophy more intelligible, his philosophy more approachable, and the causes he championed—such as the freedom of science and cultural freedom—more understandable. Applying his notion of tacit knowing in practical directions, Jha seeks to bring the study of Polanyi’s philosophy out of the specialists’ enclave and into such fields as ethics and clinical medicine.

In the present paper, we discuss Husserl's deep account of the notions of ?calculation? and of arithmetical ?operation? which is found in the final chapter of the Philosophy of Arithmetic, arguing that Husserl is as far as we know the first scholar to reflect seriously on and to investigate the problem of circumscribing the totality of computable numerical operations. We pursue two complementary goals, namely: (i) to provide a formal reconstruction of Husserl's intuitions, and (ii) to demonstrate on the basis (...) of our reconstruction that the class of operations that Husserl has in mind turns out to be extensionally equivalent to the one that, in contemporary logic, is known as the class of partial recursive functions.

This paper analyzes Mally’s system of deontic logic, introduced in his The Basic Laws of Ought: Elements of the Logic of Willing (1926). We discuss Mally’s text against the background of some contributions in the literature which show that Mally’s axiomatic system for deontic logic is flawed, in so far as it derives, for an arbitrary A, the theorem “A ought to be the case if and only if A is the case”, which represents a collapse of obligation. We then (...) try to sort out and understand which axioms are responsible for the collapse and consider two ways of amending Mally’s system: (i) by changing its original underlying logical basis, that is classical logic, and (ii) by modifying Mally’s axioms.

The history of modern modal logic is too often presented as an American success story that started with the work of the Harvard philosopher C. I. Lewis, while prewar modal logic research in Europe is passed off as a side-show of well-intended failures. As a contribute towards correcting this picture, we carefully analyze and reconsider Oskar Becker’s pioneering work On the Logic of Modalities (1930), highlighting its influence on the early development of modal logic in the decade 1930 - 1940.

During the sixteenth century Galen's De constitutione artis medicae enjoyed a great success: in about fifty years it received four different Latin translations and three commentaries. Certainly this is also true of other medical classical texts, but such success is surprising for a treatise which did not have a wide circulation either in the Middle Ages or in the seventeenth century and later. In fact it is preserved in its entirety in only one Greek manuscript and in a Latin translation (...) by Niccolò of Reggio, who worked mainly for King Robert I in Naples in the first half of the fourteenth century. Furthermore, in his edition of 1679 René Chartier made a mistake, which the humanistic editors of the Greek Galen had avoided. The last part of the De const, art. med. itself enjoyed a considerable fortuna as an independent tract on prognosis in the Greek and Latin manuscript tradition. The editors of the Aldine and the Basle editions knew such an excerptum, at least in the manuscript Par. gr. 2165 of the sixteenth century, and rightly decided not to print it. Chartier found it in the manuscript Par. gr. 2269 of the fifteenth or sixteenth century, and published it in the wrong belief that it was a new treatise of Galen's . He was followed by Carl Gottlob Kühn in his edition of 1821, who printed the De const, art. med. in the first volume and the De praesagitura in vol. xix.497–511. The error was not publicly detected until Kalbfleisch in 1896. (shrink)

The text approaches the phenomenon of transnational migration movements in the globalized world as a question related to the specific borders and mobilities of philosophy. The circulation of philosophical ideas and subjectivities between different countries and languages is challenged as a form of transnational citizenship. This main thesis will be examined in the light of the building process of the concept of belonging in the political theory of Hannah Arendt in relation to her German and US-American audiences. I will first (...) explain the approach of the transnational circulation of ideas as well as its presumption, the consideration of philosophy as a specific social practice. I will then explore the mutations of Arendt’s thinking on belonging along a close reading and a contextualization of some of her German and English texts. The contradictions in Arendt’s conceptualizations of the idea of belonging will be finally reexamined as practices of constructing transnational social and intellectual frames. (shrink)

BackgroundSeveral investigations have addressed the process of balance adaptation to external perturbations. The adaptation during unperturbed stance has received little attention. Further, whether the current sensory conditions affect the adaptation rate has not been established. We have addressed the role of vision and haptic feedback on adaptation while standing on foam.MethodsIn 22 young subjects, the analysis of geometric and spectral variables of the oscillation of the centre of feet pressure identified the effects of vision, light-touch or both in the anteroposterior (...) and mediolateral direction over 8 consecutive 90 s standing trials.ResultsAdaptation was obvious without vision and tenuous with vision. With trial repetition, path length and median frequency diminished with EC while sway area and mean level of the spectrum increased. The low- and high-frequency range of the spectrum increased and decreased in AP and ML directions, respectively. Touch compared to no-touch enhanced the rate of increase of the low-frequency power. Spectral differences in distinct sensory conditions persisted after adaptation.ConclusionBalance adaptation occurs during standing on foam. Adaptation leads to a progressive increase in the amplitude of the lowest frequencies of the spectrum and a concurrent decrease in the high-frequency range. Within this common behaviour, touch adds to its stabilising action a modest effect on the adaptation rate. Stabilisation is improved by favouring slow oscillations at the expense of sway minimisation. These findings are preliminary to investigations of balance problems in persons with sensory deficits, ageing, and peripheral or central nervous lesion. (shrink)

Two hundred years ago Bernard Bolzano published a booklet on the philosophy of mathematics that is the first major step forward in this area since Pascal’s De l’esprit géométrique. Following Aristotelian lines Bolzano distinguishes in his opusculum two kinds of proofs, those that simply show that something is the case, and those that explain why something is the case. In his Wissenschaftslehre this contrast reappears as that between derivability and consecutivity . Husserl takes up some of Bolzano’s key concepts in (...) his Prolegomena to Pure Logic. In this paper I discuss, among other things, the question whether consecutivity can be regarded as a special case of derivability, as Husserl seems to think, and I contrast Bolzano’s rejection of any appeal to self-evidence with Husserl’s reliance on this notion.Genau vor zweihundert Jahren erschienen Bernard Bolzano Beyträge zu einer begründeteren Darstellung der Mathematik. Dieses Büchlein ist der erste Meilenstein in der Geschichte der Philosophie der Mathematik seit Pascals De l’esprit géométrique. Im Anschluss an Aristoteles unterscheidet Bolzano in seinem Opusculum zwei Arten von Beweisen: solche, die nur dartun, dass etwas der Fall ist, und solche, die erklären warum etwas der Fall ist. Im seiner Wissenschaftslehre erscheint dieser Kontrast als der zwischen Ableitbarkeit und Abfolge. Husserl übernimmt einige von Bolzanos Grundbegriffen in seinen Prolegomena zur reinen Logik. In diesem Aufsatz diskutiere ich u.a. die Frage, ob Abfolge ein Spezialfall von Ableitbarkeit ist, wie Husserl anzunehmen scheint, und ich kontrastiere Bolzanos Ablehnung jeder Berufung auf Evidenz mit Husserls Einstellung.

This article approaches the paradigm shift of datafication from the perspective of civil society. Looking at how individuals and groups engage with datafication, it complements the notion of “data politics” by exploring what we call the “contentious politics of data”. By contentious politics of data we indicate the bottom-up, transformative initiatives interfering with and/or hijacking dominant processes of datafication, contesting existing power relations or re-appropriating data practices and infrastructure for purposes distinct from the intended. Said contentious politics of data is (...) articulated in an array of practices of data activism taking a critical stance towards datafication. In data activism, data as mediators take a central role, both as part of an action repertoire or as objects of struggle in their own right. Leveraging social movement studies and science and technology studies, this theoretical essay argues that data activism can be mapped along two analytical dimensions: “data as stakes” vs. “data as repertoires”, and “individual practice vs. collective action”. Mapping action repertoires and tactics along these axes allows us to chart the potential emergence of a political data subject at the intersection of these two dimensions. This furthers our understanding of people’s engagement with data in relation to other forms of activism and existing work in social movement studies. It also helps us interpreting potential trajectories of contemporary social movements, as they increasingly interface with data, devices and platforms. (shrink)

The aim of this paper is to analyze the concept of “world” in Karl Jaspers’ Psychology of Worldviews, to show how the tension between the theoretical-contemplative and existential approaches finds evident expression in the different roles that the “world” plays in the first and second parts of this work. In the first part, the world is still the object of a subject, although this relationship is neither evaluative nor only gnoseological, but is also the result of an Erlebnis, thus presenting (...) itself as a lived world. In the second part, beginning with the section on spiritual spheres, the world is characterised not only as a place of man’s action, but also as a shock, a resistance that acts upon man. The essay goes on to question whether it is possible to find a different approach to mental illness. (shrink)

The present study examined whether cinematographic editing density affects viewers’ perception of time. As a second aim, based on embodied models that conceive time perception as strictly connected to the movement, we tested the hypothesis that the editing density of moving images also affects viewers’ eye movements and that these later mediate the effect of editing density on viewers’ temporal judgments. Seventy participants watched nine video clips edited by manipulating the number of cuts (slow‐ and fast‐paced editing against a master (...) shot, unedited condition). For each editing density, multiple video clips were created, representing three different kinds of routine actions. The participants’ eye movements were recorded while watching the video, and the participants were asked to report duration judgments and subjective passage of time judgments after watching each clip. The results showed that participants subjectively perceived that time flew more while watching fast‐paced edited videos than slow‐paced or unedited videos; by contrast, concerning duration judgments, participants overestimated the duration of fast‐paced videos compared to the master‐shot videos. Both the slow‐ and the fast‐paced editing generated shorter fixations than the master shot, and the fast‐paced editing led to shorter fixations than the slow‐paced editing. Finally, compared to the unedited condition, editing led to an overestimation of durations through increased eye mobility. These findings suggest that the editing density of moving images by increasing the number of cuts effectively altered viewers’ experience of time and add further evidence to prior research showing that performed eye movement is associated with temporal judgments.

Background Ethics is a fundamental component of nursing education to increase students’ moral competence and moral reasoning abilities. However, the core ethics content that should be included in undergraduate education has not been established to date at the international level. Aim To identify the core contents required in formal undergraduate education to ensure morally competent nurses. Research Design An international workshop-research study design in 2023 reported here according to the COnsolidated criteria for REporting Qualitative research. Participants and Research Context Five (...) countries in the context of Promoting a Morally Competent Nurse project participated. In each country, two workshops took place, one with nurse professionals and one with patients’ representatives for a total of 58 individuals (32 and 26, respectively). After being translated into English language, data were categorized deductively. The Dublin Learning Outcomes Descriptors and the blueprint methodology were applied. Ethical Considerations The research protocol was ethically approved in every country where the study was performed. Results A total of 59 core content elements emerged, with ‘ethics of individualized/tailored/patient-centred care’ ( n = 8) and ‘empathy’ ( n = 6) as the most suggested. Nearly half ( n = 26) of the core content items suggested were reported only once (e.g. ‘priority setting’) while overall several referred to ‘communication skills’ ( n = 17). A diverse richness across countries emerged, with some suggesting a few items, and others providing several. Similarly, professionals and patients in most countries agreed that some contents of individualized care, empathy and responsibility should be taught in nursing education, but several core contents were mentioned by only one group of participants and in one country. Conclusion The lack of convergence on core content to be taught suggests that different views are still present. Merging these perspectives may stimulate a reciprocal understanding between professionals and patients, as well as across countries, and support the identification of commonalities and differences to further harmonize undergraduate education in the field.

Cet article se focalise sur un aspect précis du concept de temps dans l’éducation, sur les priorités que les temps futurs de l’éducation doivent choisir comme les directions les plus pertinentes pour nos sociétés. Les temps structurent et accompagnent la vie de chacun, marquent le passage entre les générations et deviennent un indicateur du développement des sociétés. Le rôle de la réflexion sur l’éducation est de s’atteler aux problématiques qui se dessinent à chaque période, et lui sont liées en termes (...) d’époque spécifique. Ceci implique d’ouvrir les frontières de la recherche vers des objets toujours vus comme nouveaux, au moins en partie, et d’envisager des opportunités et des défis importants et urgents, en ce que par leur condition de nouveauté, ces éléments inattendus sont susceptibles de former un projet tourné vers l’avenir. Au cours de cette réflection, nous proposons d’imaginer des futurs dans lesquels la résilience aux changements profonds et aux mutations complexes est présente. Celle-ci implique d’engager une réflexion sur l’avenir des connaissances et des valeurs qui sont plus importantes et urgents pour les savoirs et pour les sociétés. (shrink)

This paper proposes a political understanding of human rights which allows not to dissolve the contradiction between the positive and the normative aspect entailed in the idea and the institution of human rights, but rather to keep them together dialectically. I discuss the relationality of human rights through Hannah Arendt’s idea of the right to have rights and I develop it further through Jacques Rancière’s concept of subjectivity. This allows me to explain the dialectic of the human rights as a (...) conflict between existing positive rights, which assign specific subjects or groups to specific territories and legal spheres, and a universal claim of human equality and freedom, which is challenged from excluded, unclassified social groups and which is performed in situations of protests. I further explain the radical democratic potential of human rights on the paradigmatic case of struggles for a right to global movement and to political belonging. In order to grasp the complexity of those subjectivity practices, I distinguish four different dimensions of subjectivity: a legal and political one, an affective one, an epistemic one and finally an ethical transcultural one.

The COVID-19 pandemic served as a catalyst to build a stronger European Health Union to protect the health of Europeans and to develop a new Global Health Strategy to contribute to global health security. In positioning itself as a key player in global health governance, the EU seeks to assert its responsibility as a global health actor and deepen its leadership in global health law.
