The present paper focuses on the antecedents of solidarity behavior towards Ukrainian refugees, specifically examining the role of subjective uncertainty generated in public opinion by the aggression of Ukraine on feelings of compassion and perceptions of refugees as a threat. Based on pooled data from six representative samples collected in different waves during the first six months of the Russian army’s invasion of Ukraine among a representative sample of adult Italian citizens (N = 6,063), the study provided support for the (...) intensification hypothesis, suggesting that uncertainty can act as an affective amplifier. Indeed, the results showed that uncertainty increased perceptions of refugees as a threat (acting on its emotional component, i.e., anxiety), but also feelings of compassion, which is a main driver of solidarity. Moreover, compassion seemed to reduce the (perceived) threat posed by refugees on an economic, cultural, security, or political level. The pattern of relationships tested in the model proved to be stable across different areas of the country and for the first 6 months of the Russian invasion, suggesting that the empathic concern generated by the suffering of the Ukrainian population under attack did not significantly diminish its effects over the period considered.

Let M be an o-minimal expansion of a real closed field. Let G be a definably compact definably connected abelian n-dimensional group definable in M. We show the following: the o-minimal fundamental group of G is isomorphic to ℤn; for each k>0, the k-torsion subgroup of G is isomorphic to n, and the o-minimal cohomology algebra over ℚ of G is isomorphic to the exterior algebra over ℚ with n generators of degree one.

Quantum electrodynamics presents intrinsic limitations in the description of physical processes that make it impossible to recover from it the type of description we have in classical electrodynamics. Hence one cannot consider classical electrodynamics as reducing to quantum electrodynamics and being recovered from it by some sort of limiting procedure. Quantum electrodynamics has to be seen not as a more fundamental theory, but as an upgrade of classical electrodynamics, which permits an extension of classical theory to the description of phenomena (...) that, while being related to the conceptual framework of the classical theory, cannot be addressed from the classical theory.

The paper explains the application of a Social Innovation Based Transformative Learning pedagogical approach in an undergraduate, final year business ethics course taught at an Australian university. Using social innovation as an enabling process to extend students’ cognitive, behavioural and managerial competencies in an integrated manner, the paper describes how the SIBTL approach helps ethics teachers to promote students’ ethical action.

This paper is dedicated to extending and adapting to modal logic the approach of fractional semantics to classical logic. This is a multi-valued semantics governed by pure proof-theoretic considerations, whose truth-values are the rational numbers in the closed interval $[0,1]$. Focusing on the modal logic K, the proposed methodology relies on three key components: bilateral sequent calculus, invertibility of the logical rules, and stability (proof-invariance). We show that our semantic analysis of K affords an informational refinement with respect to the (...) standard Kripkean semantics (a new proof of Dugundji’s theorem is a case in point) and it raises the prospect of a proof-theoretic semantics for modal logic.

Qual o sentido da vida? Por que aqui estamos? Será destino? Será escolha? Neste livro, Mario Sergio Cortella e Leandro Karnal, dois dos maiores pensadores contemporâneos no Brasil, se encontram para refletir sobre essas questões que há séculos fascinam e intrigam a humanidade. A ciência, a filosofia, a religião e a arte têm oferecido algumas possibilidades de resposta que os autores discutem aqui. Afinal, pode ser aterrador imaginar que não há um destino, algo que explique a nossa existência. Por (...) outro lado, a ausência de sentido nos deixa livres para ser e viver conforme desejarmos - embora isso implique também responsabilidade. Mas somos mesmo livres? Seja escolha ou destino, seja a vida um drama que vamos tecendo ou uma tragédia anunciada, fato é que estamos sempre a procurar algum propósito que torne a existência mais significativa. Mas o que explica que algumas pessoas tenham mais sucesso do que outras no que fazem? Seria dom, vocação ou resultado de um esforço? Como os autores apontam, talvez a vida seja menos inspiração e mais transpiração. (shrink)

In this newly edited Book XI of Plato’s Republic, to be considered as the authentic conclusion of the dialogue, Socrates meets a Stranger from Trier, and discusses with him the questions of social reform, power and future revolutions.

Mit der Digitalisierung geht ein fundamentaler, herausfordernder Wandel einher. Durch eine Begriffsbestimmung und Operationalisierung wird in diesem Beitrag der digitale Wandel aus wirtschaftsphilosophischer Sicht vorgestellt. Zunächst werden wirtschaftsphilosophische Grundlagen der Digitalisierung wie die Informationsethik erläutert, gefolgt von einer Diskussion der digitalen Wertschöpfung, die auf Überwachung aufbaut und von einer Überwachungskultur gespeist wird. Schließlich werden Zukunftsperspektiven zum Internet der Dinge, Pricing, Privatheit und der Digitalen Demokratie skizziert.

Das Buch entwickelt und verteidigt eine Form des ethischen Naturalismus. Es kreist um zwei Fragen, die durch einen Leitgedanken eng verbunden sind. Dieser Leitgedanke lautet, dass das Leben, das wir führen, mit allen seinen ethischen Aspekten als Teil der Natur anzusehen ist. Die erste Frage lautet, wie dieser Leitgedanke näher zu verstehen ist. Die zweite Frage lautet, was aus diesem Leitgedanken, so verstanden, folgt. Wie könnte das ethische Leben im Verlauf der Evolution des Menschen entstanden sein? Welche Folgen hätte das (...) für uns? Die Untersuchung setzt bei Darwins Grundeinsichten an, die sie durch die weitere Entwicklung der Theorie der Evolution durch natürliche Selektion und moderne Hypothesen zur Erklärung der Entstehung des ethischen Lebens bis zum aktuellen Stand der Diskussion verfolgt. Wie sich zeigt, ist eine naturalistische Deutung nicht nur mit ethischem Denken und Handeln vereinbar, sondern trägt auch dazu bei, dessen Strukturen zu erklären. Relativiert werden dagegen die Ansprüche vieler Moraltheorien, die von überzogenen Erwartungen im Hinblick auf die Objektivität oder die Formalisierbarkeit des Ethischen geleitet sind. Den Abschluss bildet eine Fallstudie zur Menschenwürde, die nach der Deutung dieses Buchs zwar naturalistisch umgedeutet werden muss, aber als eine zentrale ethische Idee erhalten bleiben kann.

This article discusses two general strategies that have been pursued to explain how moral thought and moral institutions might have emerged. The first is found in the tradition of those whom Nietzsche calls "English psychologists"; the second is Nietzsche's own. I begin by giving an account of the resources of "English" genealogy as represented by Paul Rée and especially Charles Darwin. On the basis of that discussion, I consider Nietzsche's objections to English genealogy in detail. I argue that as they (...) stand, these objections are inconclusive; while they are, at least to a certain extent, effective against Rée, they fail as objections to the fundamental insights of Darwin. Moreover, I argue that on reflection, the rival genealogy that Nietzsche puts forward is not nearly as well supported and cannot plausibly bear the weight of explanation alone. Finally, I ask what this entails for our conception of ethical emotion. (shrink)

This essay focuses on the impossibility of considering food as ‘a thing.’ It addresses the legal profiles of food from an interdisciplinary perspective by treating the production, signification and consumption of food as semio-spatial categories. The argument starts from the foundational premise that the dynamics of food, as a magmatic flow, comprehensively connect and transform all human activities and ecological aspects of life. Like a stream of radial projections in a mass of fluid, food functions as a semiotic membrane, embodying (...) the fundamental relationality of each human body to the whole globe. The main implication subsequently drawn from this view of ‘food’ is that to eat is always and everywhere to incorporate the entire world. Since food is the epitome of the space and time proactively and enactively involved in its production, in terms of both human activities and natural resources, by the mere fact of eating no human being can avoid recognizing themselves as a space–time cannibal. The consequences of this conclusion for food justice and its spatial dynamics are enormous, and even more so in light of the current ecological crisis. The essay thus critiques many categories related to the food politics of the ecological footprint, including sustainability, bio-diversity, food systems, and the circularity of food and resources. One proposed alternative offered is a chorological reading of human rights and their possible use as semantic-spatial transducers of the activities and phenomena inherent in the ‘food-as-omnilateral-relationship.’ The dynamic and transformative relationship between space, human rights and ecological change emerges clearly. Human action, and thus law are, then, constitutive ‘ingredients’ of food, which comes to the fore as a ubiquitous icon of the interpenetrative relationship between humanity and the becoming of the Earth; being and becoming blur. In the same vein, spaces and actions, facts and values are transformed into moving elements of an overall evolving situation that makes each a means of the other and thereby a generative factor of its significance.

This paper consists of two parts. The first criticizes the usual interpretation of the so-called existential quantifier as denoting existence. It is argued that it symbolizes “someness,” as is obvious from its definition as not-all-not, as in “Some citizens will vote,” which is analyzable as “Not all citizens will abstain from voting.” The second part of the paper argues that “existence” is fivefold: real, phenomenal, conceptual, semiotic, and fantastic. A definition and a criterion are proposed for every one of them. (...) Real existence is identified with mutability; phenomenal existence, with occurrence in someone’s sensory experience; conceptual existence, as occurrence in a conceptual system; semiotic existence, as the ability of a sign to excite a reaction in an animal perceiving it; and fantastic existence, as occurrence in a work of fiction that contains or suggests it. Finally, a general concept of existence in a given context is defined with the help of the characteristic function of the said context. In other words, an existence predicate is defined, and so Anselm’s famous proof of the existence of God is shown to be formally correct. (shrink)

Una de las características de la transmisión manuscrita de los _Tractatus _ _de Pedro Hispano es el hecho de que el tratado sobre las _Categorías _no siempre ocupa el mismo lugar al interior de la obra. En algunos manuscritos se encuentra en tercer lugar, después del tratado acerca de la _Isagoge _de Porfirio, siguiendo el orden tradicional de la _logica vetus. _Pero en algunos otros, se encuentra en quinto lugar, después del tratado sobre los _Tópicos _y antes del tratado sobre (...) la suposición. En los dos casos, el lugar de las _Categorías _de Aristóteles en la lógica es definido por la noción de “término”. El propósito de este artículo es entender por qué ocurre esta variación, ya que no es teóricamente neutral. Por tanto, para atender al problema del orden de aparición del tratado sobre las _Categorías _dentro de la lógica, se presentarán tres de los más destacados comentaristas de los _Tractatus_: Juan Buridan, Juan Versor y Pedro Tartaret. Este ejercicio proporcionará algunas conclusiones sobre la relación entre las categorías y la teoría de la suposición, y también sobre la _vexata quaestio _acerca del sujeto de las categorías.

El propósito de este artículo consiste en mostrar el carácter social del contractualismo de Fichte. Para realizar ese propósito se comienza examinando la conexión entre trabajo y ciudadanía como una condición de la legitimidad política. Luego se presenta esa conexión en el marco del siempre posible desarrollo histórico de la naturaleza humana. Por último, se indican las razones de la recepción de Fichte como un precursor del socialismo germánico.

Analyzing the Dialogue between a Philosopher and a Student of the Common Laws of England by Thomas Hobbes, the essay traces the historical tradition and the reasons for its secular underestimation. The Hobbesian text is placed within the history of English law and the controversies that accompanied and followed the revolution of 1640. It is then compared with the political works of Hobbes, showing how the silence of the law is gradually replacing the state of nature as image of the (...) death of the Commonwealth . The Dialogue proves to be a firm position in favor of an universal and equal capacity to understand what the law is. This latter is the product of the will of a sovereign, who however is the institutionalization of the authorization of the individuals who constitute it. (shrink)
