According to Leibniz’s infinite-analysis account of contingency, any derivative truth is contingent if and only if it does not admit of a finite proof. Following a tradition that goes back at least as far as Bertrand Russell, several interpreters have been tempted to explain this biconditional in terms of two other principles: first, that a derivative truth is contingent if and only if it contains infinitely complex concepts and, second, that a derivative truth contains infinitely complex concepts if and only (...) if it does not admit of a finite proof. A consequence of this interpretation is that Leibniz’s infinite-analysis account of contingency falls prey to Robert Adams’s Problem of Lucky Proof. I will argue that this interpretation is mistaken and that, once it is properly understood how the idea of an infinite proof fits into Leibniz’s circle of modal notions, the problem of lucky proof simply disappears.

The notion of being a burden to others is mostly discussed in the context of care‐intensive diseases or end‐of‐life decisions. But the notion is also crucial in decision‐making at the beginning of life, namely regarding prenatal testing. Ever more sophisticated testing methods, especially non‐invasive prenatal testing (NIPT), allow the detection of genetic traits in the unborn child that may cause disabilities. A positive result often influences the decision of the pregnant women towards a termination of the pregnancy. Thus, critics claim (...) that these testing methods send a negative message to people with disabilities. At the core of this is what we call the burden assumption. This assumption claims that children with disabilities are necessarily a burden to others, especially to their parents and other family members. In this paper, we discuss what being a burden to others means in this context and how such an attitude can be avoided without restraining reproductive autonomy. A closer examination shows that the burden assumption is mostly based on misinformation and a false model of disability. Empirical studies as well as narrative evidence from parents who raise a child with disabilities show that the burden assumption is wrong. Raising a child with disabilities does not necessarily mean a decrease in the quality of life. We show how the burden assumption can be challenged through an advanced genetic counselling that combines empirical evidence with narratives from a first‐person perspective. (shrink)

In this commentary, I focus on Jones' suggestion of a close connection between the domain of space and that of kinship. I expand on that suggestion by introducing the concept of frame of reference and show how it can possibly participate to the generation of kinship systems.

Reale's monumental work establishes the exact dimensions of Aristotle's concept of first philosophy and proves the profound unity of concept that exists in Aristotle's Metaphysics.

Digital technologies have become a crucial factor in nursing. Given the fact that many tasks could also be done by robots or AI systems, the place for the nurse in this scenario is unclear. In what way and to what extent will the implementation of ever more sophisticated technology affect nursing practice? It is the aim of this paper to analyse the potential challenges of nursing practice in the digital age. The analysis is conducted through the lens of new materialism, (...) a set of theoretical models that understand the relationship between humans and technology as dynamic and performative. According to this view, there is no prefixed essence of technology. Rather, the meaning of technology is enacted in concrete practice. The analysis shows that in past debates on technology use in nursing, the nurses’ role has been defined as guardians of humanity, defending the patient against the dehumanizing effects of technology. This role has been transferred to the digital age, where it is the duty of nurses to cushion the negative effects of digital technology. As an alternative to this outdated role, nurses should be included in processes of technology design and policymaking. Enabling nursing professionals to shape the circumstances of a digitally enhanced holistic practice may empower their status within the healthcare system and also benefit the patient by contributing to a more person‐centred care.

Pickering & Garrod (P&G) explain dialogue dynamics in terms of forward modeling and prediction-by-simulation mechanisms. Their theory dissolves a strict segregation between production and comprehension processes, and it links dialogue to action-based theories of joint action. We propose that the theory can also incorporate intentional strategies that increase communicative success: for example, signaling strategies that help remaining predictable and forming common ground.

Riassunto: Questo lavoro sviluppa due elementi, apparentemente lontani, ma per alcuni aspetti non secondari, convergenti. Per un verso l’attenzione è rivolta all’origine delle regole che disciplinano il comportamento sociale umano, oltrepassando le regole di matrice istituzionale e convenzionale, che sono spesso considerate le più nobili e le più umane, nel tentativo di far affiorare le regole più remote del nostro agire, legate al patrimonio genetico degli individui della nostra specie, al parlamento dei nostri istinti, sviluppatisi durante l’evoluzione filogenetica. Lungo questo (...) primo tratto del percorso l’articolo fa riferimento in particolare al pensiero di Konrad Lorenz e della sua scuola. Per altro verso, si seguono le tracce del pensiero etico di Lévinas, soffermandosi su alcuni punti fondamentali: il volto dell’altro, la passività, la responsabilità, al fine di porre in evidenza come tra il filosofo e l’etologo, pur nelle evidenti differenze di linguaggio, di approccio e di orizzonti, siano ravvisabili tratti e conclusioni comuni. Parole chiave: Alterità; Relazione; Istinto; Etica; Responsabilità Autrui: Ethics and anthropology in Lévinas: This paper moves along two seemingly distant paths, that turn out to converge in some significant ways. The first path leads us to the origin of what are often considered the most noble and essentially human principles that regulate our social behaviour, going beyond institutional and conventional norms. This allows us to highlight the deepest and most evolutionarily remote rules of human behaviour, related to our genetic code and instincts, which developed over phylogenetic evolution. As we move along this first path, we pay special attention to the work of Konrad Lorenz and his school. The second path follows the traces of Lévinas’ ethical thought, dwelling on some fundamental issues: the face of the other, passivity, and responsibility, and helps us shed light on some ideas and conclusions that are common to the philosopher and the ethologist, despite their clear differences in language, approach, and horizons. We hope this will show how the insights of each can be used to support of the theories of the other. Keywords: Otherness: relationship; Instinct; Ethics; Responsibility. (shrink)

Starting from the formal expressions of the hydrodynamical (or “local”) quantities employed in the applications of Clifford algebras to quantum mechanics, we introduce—in terms of the ordinary tensorial language—a new definition for the field of a generic quantity. By translating from Clifford into tensor algebra, we also propose a new (nonrelativistic) velocity operator for a spin- ${\frac{1}{2}}$ particle. This operator appears as the sum of the ordinary part p/m describing the mean motion (the motion of the center-of-mass), and of a (...) second part associated with the so-called Zitterbewegung, which is the spin “internal” motion observed in the center-of-mass frame (CMF). This spin component of the velocity operator is nonzero not only in the Pauli theoretical framework, i.e., in the presence of external electromagnetic fields with a nonconstant spin function, but also in the Schrödinger case, when the wavefunction is a spin eigenstate. Thus, one gets even in the latter case a decomposition of the velocity field for the Madelung fluid into two distinct parts, which constitutes the nonrelativistic analogue of the Gordon decomposition for the Dirac current. Explicit calculations are presented for the velocity field in the particular cases of the hydrogen atom, of a spherical well potential, and of an electron in a uniform magnetic field. We find, furthermore, that the Zitterbewegung motion involves a velocity field which is solenoidal, and that the local angular velocity is parallel to the spin vector. In the presence of a nonuniform spin vector (Pauli case) we have, besides the component of the local velocity normal to the spin (present even in the Schrödinger theory), also a component which is parallel to the curl of the spin vector.

This paper discusses the role of attention in the phenomenological analysis of intentional experience in light of the problem of the relation between consciousness, intentionality, and transcendental subjectivity. Are these concepts equivalent? Or should we rather say that there is more to intentionality (and subjectivity) than consciousness? Does subjectivity embrace an unconscious domain? And, if so, how does this unconscious, yet intentional, life of subjectivity operate and how is it related to consciousness? In order to answer these questions, the paper (...) tracks the development of Husserl’s conception of attention from the Logical Investigations to genetic phenomenology, by focusing on his analyses of temporality in the Bernau Manuscripts, on the relation between activity and passivity in the Analyses Concerning Active and Passive Synthesis, and on the issue of the self-constitution of subjectivity.

The theoretical system Lyell presented in 1830 was composed of three requirements or principles: 1) the Uniformity Principle which states that past geological events must be explained by the same causes now in operation; 2) the Uniformity of Rate Principle which states that geological laws operate with the same force as at present; 3) the Steady-state Principle which states that the earth does not undergo any directional change. The three principles form a single thesis called uniformitarianism which has been repeatedly (...) questioned and which has been reputed to be unable to face the competing directional synthesis based on the theory of the earth's cooling down. As a result, the significance of Lyell's system has been reduced to a simple actualism which admits the validity of the only Uniformity Principle. I believe that the only way to understand Lyell's role in the history of science is to maintain the unity of his synthesis. To show the Newtonian roots of this synthesis I will compare Lyell's principles and Newton's Rules of Reasoning. I will conclude with an analysis of the methodological function of principles in Lyell's scientific endeavour. (shrink)

A realidade virtual tem se tornado cada vez mais presente, o que dá origem a novas questões filosóficas: qual a natureza de experiências em realidade virtual? Seriam elas exatamente como percepções usuais, ou elas possuem algum traço que as diferencia? Seriam ilusórias? Nós argumentamos que experiências em realidade virtual não devem ser tratadas como ilusórias, assim como defendido pela maioria dos teóricos contemporâneos, mas sim como alusórias, condicionadas à incorporação do hardware e ao conhecimento prático envolvido no uso da tecnologia. (...) Para tal, abordamos sua associação com ilusões, exploramos como se relacionam com as nossas experiências do cotidiano e apresentamos nossa proposta de que podem ser compreendidas como alusórias. Em seguida mostramos que seu caráter alusório não as torna indistinguíveis de experiências não-virtuais, uma vez que os limites biológicos e sensório-motores da cognição fornecem o limiar de diferenciação, mesmo nos casos de realidade aumentada. Além disso, exploramos o surgimento da tecnologia de realidade aumentada e discutimos a possibilidade de substituir sistematicamente a percepção por projeções ilusórias. No entanto, até o momento, não há evidências empíricas que sustentem essa possibilidade. Destacamos a importância da relação entre percepção e ação no ambiente físico e argumentamos que erros pontuais em experiências virtuais não caracterizam seu estado como ilusório. (shrink)

The present work is a comment of a recent paper by Fortin and coauthors in which the authors propose the introduction of Bohmian mechanics in the philosophy of chemistry and the use of standard quantum mechanics as a mere instrument of prediction. This way would allow overcoming the obstacles found in linking molecular chemistry and quantum mechanics. Starting from some remarks on the orbital concept, we highlight and discuss some general issues that need to be taken into account when two (...) scientific theories coexist within the same investigation field, i.e. SQM and BM.
