The conditional interpretation of general categorical statements like ‘All men are animals’ as universally quantified material conditionals ‘For all x, if x is F, then x is G’ suggests that the logical structure of law statements is conditional rather than categorical. Disregarding the problem that the universally quantified material conditional is trivially true whenever there are no xs that are F, there are some reasons to be sceptical of Frege’s equivalence between categorical and conditional expressions. -/- Now many philosophers will (...) claim that the material conditional interpretation of laws statements, dispositions ascriptions, or any causal claim is generally accepted as wrong and outdated. Still, there seem to be some basic logical assumptions that are shared by most of the participants in the debate on causal matters which at least stems from the traditional truth functional interpretation of conditionals. This is indicated by the vocabulary in the philosophical debate on causation, where one often speaks of ‘counterfactuals’, ‘possible worlds’ and ‘necessity’ without being explicit on whether or to what extent one accepts the logical-technical definition of these notions. To guarantee a non-Humean and non-extensional approach to causal relations, it is therefore important to be aware of the logical and metaphysical implications of the technical vocabulary. -/- In this paper we want to show why extensional logic cannot deal with causal relations. Via a logical analysis of law-like statements ‘All Fs are Gs’ we hope to throw some new light on interrelated notions like causation, laws, induction, hypotheticality and modality. If successful, our analysis should be of relevance for a deeper understanding of any type of causal relations, whether we understand them to be laws, dispositions, singulars or categoricals.

This paper argues that the technical notion of conditional probability, as given by the ratio analysis, is unsuitable for dealing with our pretheoretical and intuitive understanding of both conditionality and probability. This is an ontological account of conditionals that include an irreducible dispositional connection between the antecedent and consequent conditions and where the conditional has to be treated as an indivisible whole rather than compositional. The relevant type of conditionality is found in some well-defined group of conditional statements. As an (...) alternative, therefore, we briefly offer grounds for what we would call an ontological reading: for both conditionality and conditional probability in general. It is not offered as a fully developed theory of conditionality but can be used, we claim, to explain why calculations according to the RATIO scheme does not coincide with our intuitive notion of conditional probability. What it shows us is that for an understanding of the whole range of conditionals we will need what John Heil (2003), in response to Quine (1953), calls an ontological point of view. (shrink)

Hva er vitenskap og hva anser vi som vitenskaplighet? Dette er spørsmål som kan være verdt å se nøyere på før vi aksepterer at det er et klart skille mellom den etablerte skolemedisinen og alt det vi kaller ”alternativ medisin” eller ”alternativ behandling”. For hva er det egentlig som gjør noe til etablert og noe annet til et alternativ? Er den etablerte medisin mer vitenskapelig enn den alternative, ved at den for eksempel benytter seg av mer vitenskapelige metoder? Er resultatene (...) til den etablerte behandlingen ”vitenskapelig bevist”, mens den alternative behandlingen ikke har noen vitenskapelig dokumenterte resultater å vise til? Og har den alternative tradisjonen et forklaringsproblem med hensyn til hvorfor behandlingen eventuelt fungerer, mens den etablerte tradisjonen kan henvise til entydige kausale modeller? -/- Hva vi er tilbøyelig til å svare på slike spørsmål avhenger av hva vi legger i begrepene vitenskap og vitenskapelighet.

Background Equal access to healthcare is a core principle in Norway’s public healthcare system. The COVID-19 pandemic challenged healthcare systems in the early phase – in particular, related to testing and hospital capacity. There is little knowledge on how older people experienced being infected with an unfamiliar and severe disease, and how they experienced the need for healthcare early in the pandemic Aim To explore the experiences of older people infected by COVID-19 and their need for testing and hospitalisation. Research (...) design An explorative and descriptive approach, with qualitative interviews conducted in October 2020. Participants and research context Seventeen participants above 60 years of age hospitalised due to COVID-19 during spring 2020 were recruited 6 months after discharge. Ethical considerations Ethical approval was granted by the Regional Committee for Medical and Health Research Ethics in South-Eastern Norway (155425). Findings The main finding was that the informants experienced vulnerability and arbitrariness. This finding was supported by three sub-themes: experiences with a severe and unfamiliar disease, the strict criteria and the importance of someone advocating needs. Discussion Participants described varying access to healthcare. Those who did not meet the national criteria to be tested or hospitalised struggled against the system. Findings reveal arbitrary access to healthcare, in contrast to Norway’s ethical principle of fair and just access to health services. Moreover, to access and receive necessary healthcare, informants were dependent on their next-of-kin’s advocacy. Conclusion Even when dealing with an unfamiliar disease, health professionals’ assessments of symptoms must be performed with an ethical obligation to applicate competent appraisal and the exercise of discernment; this is in line with care ethics and ethical standards for nurses. These perspectives are a significant part of caring and the intension of doing good. (shrink)

The early coronavirus disease 2019 (COVID‐19) outbreak inflicted vulnerability on individuals and societies on a completely different scale than we have seen previously. The pandemic developed rapidly from 1 day to the next, and both society and individuals were put to the test. Older people's experiences of the early outbreak were no exception. Using an abductive analytical approach, the study explores the individual experiences of vulnerability as described by older people hospitalised with COVID–19 in the early outbreak. In these older (...) people, we found that the societal context and the individual experiences of vulnerability were inextricable linked. The study demonstrates that despite significant individual stress, informants displayed an interesting ability to also view their situation to reorient their perspective. The experience of vulnerability is both conditional and individual, which imposes a degree of unpredictability that neither they nor others were able to negotiate. The article discusses the phenomenon of unpredictability in light of a modern society with regard to how individuals and society may encounter unexpected events in the future where the potential to reorient will be vital.

Central to Nozick’s Anarchy, State and Utopia is a defense of the legitimacy of the minimal state’s use of coercion against anarchist objections. Individuals acting within their natural rights can establish the state without committing wrongdoing against those who disagree. Nozick attempts to show that even with a natural executive right, individuals need not actually consent to incur political obligations. Nozick’s argument relies on an account of compensation to remedy the infringement of the non-consenters’ procedural rights. Compensation, however, cannot remedy (...) the infringement, for either it is superfluous to Nozick’s account of procedural rights, or it is made to play a role inconsistent with Nozick’s liberal voluntarist commitments. Nevertheless, Nozick’s account of procedural rights contains clues for how to solve the problem. Since procedural rights are incompatible with a natural executive right, Nozickeans can argue that only the state can enforce individuals’ rights without wronging anyone, thus refuting the anarchist.
