This paper raises the questions: 'What do we expect from nursing ethics?' and 'Is the literature of nursing ethics any different from that of medical ethics?' It is suggested that rather than develop nursing ethics as a separate field writers in nursing ethics should take a lead in making the patient the central focus of health care ethics. The case is made for empirical work in health care ethics and it is suggested that a good way of setting about this (...) is to ask practising nurses about the real ethical problems they encounter.

Este artigo busca ressoar um percurso de sensibilização vivido por um professor que descobre a força desestabilizadora e inspiradora da infância das crianças durante as aulas de filosofia. Ao investigar a (im)possibilidade das crianças fazerem filosofia, vemos semelhanças com a experiência de tocar violão, o qual transformamos em um personagem conceitual para nos ajudar a (re)pensar o ensino de filosofia para crianças. Ensaiamos, neste texto, formas de explorar os sentidos que se desprendem de experiências vividas entre a infância e a (...) filosofia a partir de encontros vividos em salas de aula, para encontrarmos/criarmos possibilidades de alimentarmos essa investigação ao invés de pôr fim a ela. Um exercício que nos possibilita encontrar/construir formas mais acolhedoras, sensíveis e inventivas de fazer, viver e habitar a educação entre a infância e a filosofia na escola. Deparamo-nos, assim, com ideia (conceito-corpo) de devir-violão, a qual trabalhamos a partir dos encontros com Gilles Deleuze e Jean-Luc Nancy. Vida. É disso que se trata este texto; e pesquisa, pois, no que diz respeito à educação, essas duas coisas se confundem, acontecem juntas, co-partilham percursos, são inseparáveis; do mesmo modo que não podemos separar o som do arrepio que causam em nossa pele. O texto é, antes de tudo, um convite a nos colocarmos à escuta daquilo que nos toca, não para explicar ou fundamentar nossas práticas, mas sim para descobrir e inventar sentidos: ser em-com-outros, entre educação, filosofia, infâncias e escolas.

Descartes's distinction between res cogitans and res extensa is a paradigmatic concept on which Western thought has been grounded. The reductionist and objectivistic approach of modern science draws its fundamental premise from it. This dualism has also instigated a view of human as separate from nature. The complexity approach in its most radical form questions many of these assumptions, asserting that the subjective and objective dimensions are involved in a relation of mutual determination and dependence. This article argues that if (...) the dualistic metaphysics is replaced by a vision emphasizing this mutual dependence, a new way of interacting with nature may also be fostered. (shrink)

Commonsense ontology contains both continuants and occurrents, but are continuants necessary? I argue that they are neither occurrents nor easily replaceable by them. The worst problem for continuants is the question in virtue of what a given continuant exists at a given time. For such truthmakers we must have recourse to occurrents, those vital to the continuant at that time. Continuants are, like abstract objects, invariants under equivalences over occurrents. But they are not abstract, and their being invariants enables us (...) to infer both their lack of temporal parts and that non-invariant predications about them must be relativized to times. \\\ [Joseph Melia] In this paper I try to eliminate occurrents from our ontology. I argue against Simons' position that occurrents are needed to supply truthmakers for existential claims about continuants. Nevertheless, those who would eliminate occurrents still need some account of our willingness to assert sentences that logically entail their existence. Though it turns out to be impossible to paraphrase away our reference to occurrents, I show that the truthmakers for such sentences are facts that involve only continuants. This is enough to allow us to regard our ordinary talk about occurrents as fictional. Finally, I argue that a proper conception of the underlying temporal facts about continuants can both avoid the problematic tensed theory of time and the problem of temporary intrinsics. (shrink)

According to the indispensability argument, the fact that we quantify over numbers, sets and functions in our best scientific theories gives us reason for believing that such objects exist. I examine a strategy to dispense with such quantification by simply replacing any given platonistic theory by the set of sentences in the nominalist vocabulary it logically entails. I argue that, as a strategy, this response fails: for there is no guarantee that the nominalist world that go beyond the set of (...) sentences in the nominalist language such theories entail. However, I argue that what such theories show is that mathematics can enable us to express possibilities about the concrete world that may not be expressible in nominalistically acceptable language. While I grant that this may make quantification over abstracta indispensable, I deny that such indispensability is a reason for accepting them into our ontology. I urge that the nominalist should be allowed to quantify over abstracta whilst denying their existence and I explain how this apparently contradictory practice (a practice I call 'weaseling') is in fact coherent, unproblematic and rational. Finally, I examine the view that platonistic theories are simpler or more attractive than their nominalistic reformulations, and thus that abstract ought to be accepted into our ontology for the same sorts of reasons as other theoretical objects. I argue that, at least in the case of numbers, functions and sets, such arguments misunderstand the kind of simplicity and attractiveness we seek. (shrink)

Cybernetic governmentality weakens the capacity of resistant subjectivities to struggle against neoliberal rationality because digitalized subjectivation processes are constantly pushed towards the logics of the market and into codifications of competitive evaluation. Despite the potential for new forms of collectivity contained in the concept of virtuality, technological evolution has disseminated a systemic form of digitality that operates not through collective procedures but through subjective-individualistic ones. Hence arises a danger that was indicated by Deleuze decades ago: that of confusing the virtual (...) with the possible. By constructing a genealogy that is built around Pierre Levy’s optimistic representation of cyberspace, Bernard Stiegler’s work on the contemporary disenchantment of the computerized world, Baudrillard’s metaphysics of code and Antoinette Rouvroy’s analysis of algorithmic governmentality, we will demonstrate that digitality is between us and that this amounts to an irreversible fact entailing a critical confrontation with its current manifestation.

Complex crises like the coronavirus pandemic are showing us that modern societies are becoming increasingly unable to live in equilibrium with nature. These crises are the result of multiple causes, which interact at different scales and across different domains. Therefore, investigating their proximate causes is not enough to fully understand them. It is also crucial to take into account the structural factors involved. As concerns the global pandemic, I suggest four levels of analysis: (i) the surface or “proximate” level of (...) the crisis; (ii) the human–environment–animal interface, as pointed out by the One Health approach; (iii) the broader socioeconomic context; and (iv) the deeper or worldview level. Furthermore, I argue that there is the need for a mindset shift if we want to properly trace causality. Much more attention must be given to the study of multilevel connecting patterns and nonlinear mechanisms as the producers of emergent global effects. (shrink)

Health Care Ethics examines the way ethical dilemmas are played out in everyday clinical practice and argues for an approach to ethical decision-making which focuses more on patient needs than competing professional interests. While advances in medical science and technology have improved the ability to save and prolong lives, they have also given rise to fundamental questions about what constitutes life and personhood, especially in the context of what are termed 'persistent vegetative state' and 'brain death'. Drawing on the example (...) of intensive care where such questions feature strongly in everyday practice, Kath M Melia examines how decisions are taken within the context of multiprofessional teamworking, including · whether to admit a patient and commence treatment · what the aim of treatment should be (i.e. palliation, care or cure) · when to limit, withhold or withdraw treatment · when to donate organs. As an area in which different professional groups work closely together, the author argues that there are lessons to be learnt from intensive care which can be applied to ethical decision making in all areas of health care for the greater good of patients. The book makes a significant contribution to the literature on ethics in health care and to the development of ethical decision making which prioritises the needs of patients. It is essential reading for ethicists, sociologists and health care professionals. (shrink)

(1) The average Mum has 2.4 children. (2) The number of Argle’s fingers equals the number of Bargle’s toes. (3) There are two possible ways in which Joe could win this chess game. In the right contexts, and outside the philosophy room, all the above sentences may be completely uncontroversial. For instance, if we know that Joe could win either by exchanging queens and entering an endgame, or by initiating a kingside attack then, if ignorant of Quine’s work on ontology, (...) we would take (3) to be uncontroversially true.

The potential for jointly using or integrating Western science and indigenous knowledge, especially in such fields as environmental management, is a hotly debated topic nowadays. However, the difficulties involved in such a task are not always fully understood and co-management experiences achieved only partially the expected outcomes. In this contribution, I show how a sound combination of the two bodies of knowledge would be possible only if there is a way to accommodate different interpretations of reality and knowledge criteria. The (...) issue should then be faced at the epistemological level too, discussing the possibility and implications of a genuine epistemic pluralism. With reference, among others, to Feyerabend’s later writings, here I illustrate some possible insights for addressing the matter that a Western perspectivist stance could provide. (shrink)

This introduction to modality places the emphasis on the metaphysics of modality rather than on the formal semetics of quantified modal logic. The text begins by introducing students to the "de re/de dicto" distinction, conventionalist and conceptualist theories of modality and some of the key problems in modality, particularly Quine's criticisms. It then moves on to explain how possible worlds provide a solution to many of the problems in modality and how possible worlds themselves have been used to analyse notions (...) outside modality such as properties and propositions. Possible worlds introduce problems of their own and the book argues that to make progress with these problems a theory of possible worlds is required. The pros and cons of various theories of possible worlds are then examined in turn, including those of Lewis, Kripke, Adams, Stalnaker and Plantinga. (shrink)

Model theoretic considerations purportedly show that a certain version of structural realism, one which articulates the nvtion of structure via Ramsey sentences, is in fact trivially true. In this paper we argue that the structural realist is by no means forced to Ramseyfy in the manner assumed in the formal proof. However, the structural realist's reprise is short-lived. For, as we show, there are related versions of the model theoretic argument which cannot be so easily blocked by the structural realist. (...) We examine various ways in which the structural realist may respond, and conclude that the best way of blocking the model theoretic argument involves formulating his Ramseyfied theories using intensional operators.

1. The problemLewis identifies the monadic property being F with the set of all actual and possible Fs; the dyadic relation R is identified with the set of actual and possible pairs of things that are related by R; and so on . 1 Egan has argued that the fact that some properties have some of their properties contingently leads to trouble: " Let @ be the actual world, in which being green is [someone's] favourite property, and let w be (...) a world in which being green is [nobody's] favourite property. Since being green is somebody's favourite property in @, it must be a member of … being somebody's favourite property. Since being green is not anybody's favourite property in w, it must not be a member of being somebody's favourite property. Contradiction. " Egan suggests identifying properties with functions from worlds to extensions. However, as Lewis and others have complained, this has the drawback of turning monadic properties into relations . 2 In this article, we shall show that the Lewisian has the resources to block the above argument while simultaneously respecting the adicity of the relevant property and the contingency of the predication without changing his theory of properties. However, our analysis reveals a hidden ambiguity in the Lewisian conception of properties, and on either disambiguation the resulting account of properties seems inadequate.2. On ‘being someone's favourite property’The phrase ‘ being someone's favourite property’ is ambiguous. Given Lewis's ontology of possibilia, where the phrase picks out a monadic property it is not one that is possessed contingently; where it picks out a property that is possessed contingently it is not one that is monadic. But the argument works only if being someone's favourite property is both monadic and possessed contingently.Why should …. (shrink)

We study a regularized version of Van Hove’s 1952 model, in which a quantum field interacts linearly with sources of finite width lying at fixed positions. We show that the central result of Van Hove’s 1952 paper on the foundations of Quantum Field Theory, the orthogonality between the spaces of state vectors which correspond to different values of the parameters of the theory, disappears when a well-defined model is considered. We comment on the implications of our results for the contemporary (...) relevance of Van Hove’s article. (shrink)

In this paper I claim that Earman and Norton 's hole argument against substantivalist interpretations of General Relativity assumes that the substantivalist must adopt a conception of determinism which I argue is unsatisfactory. Butterfield and others have responded to the hole argument by finding a conception of determinism open to the substantivalist that is not prone to the hole argument. But, unfortunately for the substantivalist, I argue this conception also turns out to be unsatisfactory. Accordingly, I search for a conception (...) of determinism that is both independently plausible and capable of blocking the hole argument. (shrink)

During the COVID-19 pandemic, scientific experts advised governments for measures to be promptly taken; they also helped people to understand the situation. They carried out this role in the face of a worldwide emergency, when scientific understanding was still underway. Public scientific disputes also arose, creating confusion among people. This article highlights the importance of experts’ epistemic stance under these circumstances. It suggests they should embrace the intellectual virtue of epistemic humility, regulating their epistemic behavior and communication accordingly. In so (...) doing, they would also favour the functioning of the broad network of knowledge-based experts, which is required to properly address all the aspects of the global pandemic. (shrink)

In this note, I defend Melia 2000 against objections in Daly and Langford 2010. I show that my formulation of the Comprehension Schema is correct while their modification is inadequate and that their approach to the problem through infinitary sentences is irrelevant to my original arguments. Finally, I argue that it is not a puzzle that we could find mathematics indispensable in our theorising, even when the mathematics is false.

The author, starting from what is currently known about cup-marks and their distribution in the north-western Italian alpine area, formulated a hypothesis on their material and ritual functions in the Neolithic period. It is conceivable that cup-marks were originally carved in connection with the ritual use of Amanita muscaria, and that they may later have assumed other functions as well.
