In this paper Grice's requirements for assertability are imposed on the disjunction of Classical Logic. Defining material implication in terms of negation and disjunction supplemented by assertability conditions, results in the disappearance of the most important paradoxes of material implication. The resulting consequence relation displays a very strong resemblance to Schurz's conclusion-relevant consequence relation.

This paper is a contribution to the program of constructing formal representations of pragmatic aspects of human reasoning. We propose a formalization within the framework of Adaptive Logics of the exclusivity implicature governing the connective ‘or’.Keywords: exclusivity implicature, Adaptive Logics.

This paper contains different approaches to solve the problem how to construct the ultimate position out of one’s interventions in a discussion after possibly one or more position changes. In all approaches it is the aim to come as close as possible to human reasoning. Therefore all logics are adaptive logics. The first logic is an extension of an adaptive translation into S5 of the Rescher-Manor mechanisms. The second one is a dynamic proof theory based on a technique using indices. (...) In the end a satisfactory solution is given by a dynamic proof theory expressing the idea of prioritized compatibility, i.e. compatibility step by step. (shrink)

A logic of diagnosis proceeds in terms of a set of data and one or more (prioritized) sets of expectancies. In this paper we generalize the logics of diagnosis from [27] and present some alternatives. The former operate on the premises and expectancies themselves, the latter on their consequences.

Although the personal-subpersonal distinction was first proposed in 1969 by D. Dennett, it has been approximately in the last ten years that it has received in­creasing attention and has became a widely used distinction particularly in the philosophy of mind and cognitive psychology literature. While the distinction is ubiquitous there are a few recent proposals about the relationship between the levels, namely, inter alia, the mixed horizontal explanation (Bermúdez 2000), the semantic view of computation (Peacocke 1994), and interaction without reduction (...) (Davies 2000a, b). In this paper I will first describe the way of understanding the distinction shared by the proposals aforementioned. Second, I will show some of the difficulties facing each proposal. Finally, I will suggest what I consider are the misleading assumptions that are at the root of the proposed strategies of inter-level relations. (shrink)

This study investigates virtual community-building practices and discriminatory views in PAL NWS, a Dutch-speaking Belgian far-right alternative news medium, by examining discussions in the comments sections. Thematic analysis was applied to a total of 1,127 comments by 343 users in response to 50 articles about LGBTI topics. The findings show that far-right alternative news sites can function as virtual communities that facilitate polarization. The comments exhibited a high level of hostility towards LGBTI individuals, particularly toward transgender people and public displays (...) of LGBTI inclusion. Furthermore, Muslims were homogeneously perceived as homophobes, and LGBTI topics were understood as (woke) ideological suppression by a dogmatic minority. The results of this study have implications for understanding the dynamics of comments sections on alternative media and the potential for far-right news platforms to facilitate the spread of intolerance.

This essay series attempts to stimulate the debate about the moral challenges that internationalisation confronts us with, both in the Netherlands and abroad, and in particular for Artist-in-Residencies (AIRs). The publication is a reflection on how the crisis is reconsidering our international ambitions, starting from a post-COVID society. Internationalisation is an inevitable reality, inherent to the art landscape. The current time calls for a critical reflection on major issues such as climate inequality, plurality and the Western-dominant canon. 0With contributions and (...) critical insights by Jeanne van Heeswijk, Jack Segbars, Erik Hagoort, Pascal Gielen, Cecilia Bengtsson, Merlijn Twaalfhoven, Hicham Khalidi, reinaart vanhoe and Suzanne van der Beek.

There is little information about the content of ethics consultations in pediatrics. We sought to describe the reasons for consultation and ethical principles addressed during EC in pediatrics through retrospective review and directed content analysis of EC records at St. Jude Children's Research Hospital. Patient-based EC were highly complex and often involved evaluation of parental decision making, particularly consideration of the risks and benefits of a proposed medical intervention, and the physician's fiduciary responsibility to the patient. Nonpatient consultations provided guidance (...) in the development of institutional policies that would broadly affect patients and families. This is one of the few existing reviews of the content of pediatric EC and indicates that the distribution of ethical issues and reasons for moral distress are different than with adults. Pediatric EC often facilitates complex decision making among multiple stakeholders, and further prospective research is need.. (shrink)

This article studies the conceptions of social justice of women active in transnational migrant politics over a period of roughly 20 years in the Netherlands. The novel focus on migrant women reveals that transnational politics is almost completely male-dominated and -directed. Two of the exceptions found in this article include a leftist and a Kurdish women organization supporting the communist cause in the 1980s and the Kurdish struggle in the 1990s in Turkey, respectively. In both organizations gender equality was subordinated (...) to broader ideologies of political parties in their homeland. Leftist activists in the cold war era supported a narrow definition of the "politics of redistribution," while and Kurdish activists, combined classical features of the latter with those of traditional identity politics.

Entre los filósofos que consideran que pensamos utilizando representaciones simbólicas, P. Carruthers ha defendido, versus la hipótesis del ‘lenguaje del pensamiento’ (LDP), una versión débil de la hipótesis del ‘pensamiento en lenguaje natural’ (PLN). En este trabajo, me ocuparé, en primer lugar, de mostrar las razones por las cuales Carruthers, en su defensa de la hipótesis débil del PLN, siembra cierta confusión en la polémica entre el LDP y PLN. En segundo lugar, intentaré esbozar una salida de esta confusión, ofreciendo (...) y evaluando dos opciones posibles, i.e. la estrategia trascendental y la de la inferencia a la mejor explicación revisada, para quien desee sostener una versión débil del PLN que no desvirtúe la polémica.Among the philosophers who believe that we think with symbolic representations, P. Carruthers has defended -against the ‘language of thought’ hypothesis (LOT)- a weak version of the ‘thinking in natural language’ hypothesis (TNL). In this paper, I will firstly state the reasons why I think that Carruthers throws the LOT-TNL debate into some confusion. Secondly, I will try to outline a way out of this confusion, offering and evaluating two possible options -i.e., the transcendental and the revised inference to the best explanation strategies- for those who wish to hold a weak version of TNL that does not distort the debate.

Eyal et al have recently argued that researchers should consider conducting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) human challenge studies to hasten vaccine development. We have conducted (J. L.) and overseen (L. D.) human challenge studies and agree that they can be useful in developing anti-infective agents. We also agree that adults can autonomously choose to undergo risks with no prospect of direct benefit to themselves. However, we disagree that SARS-CoV-2 challenge studies are ethically appropriate at this time, for (...) 3 reasons: (1) current scientific knowledge of SARS-CoV-2 infection is insufficient to manage risks; (2) autonomous decision making, while necessary, does not override concerns about risk; and (3) undertaking challenge studies now would imperil confidence in the research enterprise, potentially undermining the global response to the coronavirus disease 2019 (COVID-19) pandemic.

Despite recent advances in HIV prevention and treatment, high HIV incidence persists among people who inject drugs. Difficult legal and political environments and lack of services for PWID likely contribute to high HIV incidence. Some advocates question whether any HIV prevention research is ethically justified in settings where healthcare system fails to provide basic services to PWID and where implementation of research findings is fraught with political barriers. Ethical challenges in research with PWID include concern about whether research evidence will (...) be translated into practice; concerns that research might exacerbate background risks; and ethical challenges regarding the standard of HIV prevention in research. While these questions arise in other research settings, for research with PWID, these questions are especially controversial. This paper analyses four ethical questions in determining whether research could be ethically acceptable: Can researchers ensure that research does not add to the burden of social harms and poor health experienced by PWID? Should research be conducted in settings where it is uncertain whether research findings will be translated into practice? When best practices in prevention and care are not locally available, what standard of care and prevention is ethically appropriate? Does the conduct of research in settings with oppressive policies constitute complicity? We outline specific criteria to address these four ethical challenges. We also urge researchers to join the call to action for policy change to provide proven safe and effective HIV prevention and harm reduction interventions for PWID around the world. (shrink)

The best-known argument in favor of the innatism of certain mental structures is still the 'Poverty of the Stimulus Argument'. The general idea of the POSA is that the knowledge which needs to be acquired to develop a certain cognitive capacity vastly exceeds the information available in the environment, so the organism contributes innate information. A review of the literature on linguistic POSA shows that it is not yet fully clear what kind of argument this is and what it really (...) shows. This paper is intended as a diagnosis of the innateness strategy that makes use of the POSA. I will distinguish three types of POSA and argue, first, that the most appropriate type of POSA, according to certain empirical and theoretical criteria, does not seem to be sufficient for linguistic nativism and, second, that for it to be sufficient, it is usually supplemented with an armchair argument which weakens the empirical nature of the innateness hypothesis. El argumento más conocido en favor del innatismo de ciertas estructuras mentales sigue siendo el 'Argumento de la Pobreza del estímulo'. La idea general del APE es que el conocimiento que se requiere para desarrollar una cierta capacidad cognitiva excede en gran medida la información disponible en el entorno, de manera que el organismo contribuye con información innata. Un examen de la literatura del APE lingüístico muestra que aún no está del todo claro qué clase de argumento es y lo que realmente muestra. Mi objetivo en este trabajo es ofrecer un diagnóstico de la estrategia innatista que utiliza el APE. Así, distingo tres tipos de APE y argumento, en primer lugar, que la versión más apropiada, según ciertos criterios empíricos y teóricos, no parece ser suficiente para el innatismo lingüístico y, en segundo lugar, que para ser suficiente, suele complementarse con un argumento 'de sillón', cuya consecuencia es que convierte al innatismo en una hipótesis empírica debilitada.

We report on the deliberations of an interdisciplinary group of experts in science, law, and philosophy who convened to discuss novel ethical and policy challenges in stem cell research. In this report we discuss the ethical and policy implications of safety concerns in the transition from basic laboratory research to clinical applications of cell-based therapies derived from stem cells. Although many features of this transition from lab to clinic are common to other therapies, three aspects of stem cell biology pose (...) unique challenges. First, tension regarding the use of human embryos may complicate the scientific development of safe and effective cell lines. Second, because human stem cells were not developed in the laboratory until 1998, few safety questions relating to human applications have been addressed in animal research. Third, preclinical and clinical testing of biologic agents, particularly those as inherently complex as mammalian cells, present formidable challenges, such as the need to develop suitable standardized assays and the difficulty of selecting appropriate patient populations for early phase trials. We recommend that scientists, policy makers, and the public discuss these issues responsibly, and further, that a national advisory committee to oversee human trials of cell therapies be established. **NB we did not reccommend a NAC, we think it might be appropriate**.

Narrative has proven itself a continuous as well as adaptable means for environmentally oriented expression. Its role goes beyond the mediation of pre-existing knowledge imported into the realm of storytelling from other domains; rather, influential models of the natural world tend to circulate as storyworlds. This special issue of SubStance proceeds from the premise that narratives are not only a sequence of signs encoding a story but also “invisible, elusive representations that exist only in the mind”. Narrative forms generate and (...) transfer environmental knowledge; moreover, any specifically narrative concerns are important contributing factors to the models of agency, change... (shrink)

This paper examines how three Dutch political parties employ the Internet as a tool to enhance ‘digital democracy’. The potential of digital democracy is considered to be strongest in the sphere of collective action outside the domain of political institutions. In this article, however, attention is given to how institutionalized channels might be supportive of digital democracy. Three components of the democratic process – information provision, deliberation, and political decision-making – are examined in the content and user assessments of the (...) web sites of the Socialist Party, the Christian Democratic Party and the Green Party. Minor differences were found in the party web sites regarding information provision; substantial differences were found regarding the degree and nature of political deliberation available on the sites. Indicators of the third component, political decision-making, were least evident on all three web sites. User assessments of the sites and opportunities for political deliberation followed, more or less, the general public images of the related political parties. (shrink)

Hornsby defiende una interpretación muy particular de la distinción personal-subpersonal tal como fue propuesta por Dennett y de la doctrina filosófica en la que está enraizada esta distinción. Según Hornsby de la aceptación de la distinción y la doctrina se sigue una defensa de la autonomía explicativa del nivel personal. Esta defensa nos compromete con un nivel personal genuino de explicación y la idea de que los hechos subpersonales no explican hechos personales. Hornsby sostiene, además, que mientras que en Dennett (...) se defiende la autonomía del nivel explicativo personal, en Dennett post-1969 al modificarse la doctrina de base cambia la manera de entender la distinción y con ello se reniega de ambos compromisos, de lo cual se sigue un abandono de la tesis de la autonomía del nivel explicativo personal. La tesis que vamos a sostener en este trabajo es que si bien la distinción de Dennett nos compromete con , no nos compromete con . Dado que una defensa de la autonomía explicativa del nivel personal, tal como Hornsby la entiende, abarca ambos compromisos, se sigue que no hay tal defensa. En consecuencia, si bien hay algunas cuestiones que en Dennett no se plantean de manera tan explícita y clara como en Dennett post-1969, no hay un cambio sustancial en su concepción de la distinción.According to Hornsby , Dennett's personal-subpersonal distinction has as one of its consequences a defense of the autonomy of personal level explanation, and this defense is based on two commitments: the personal level is a genuine level of explanation, and subpersonal facts do not explain personal facts. Moreover, Hornsby argues that Dennett post-1969 rejects both commitments, and that he consequently abandons the autonomy thesis. In this paper we shall argue that, although Dennett's distinction is committed to , it is not committed to . Given that a defense of the autonomy, as Hornsby understands it, presupposes both commitments, it follows that there is no such defense. We hold that there is no substantial change in Dennett's conception of the distinction, although some of these issues are not as clear and explicit in Dennett 1969 as in Dennett post-1969. (shrink)

Unconsented episiotomies and other procedures during labour are commonly reported by women in several countries, and often highlighted in birth activism. Yet, forced caesarean sections aside, the ethics of consent during labour has received little attention. Focusing on episiotomies, this paper addresses whether and how consent in labour should be obtained. We briefly review the rationale for informed consent, distinguishing its intrinsic and instrumental relevance for respecting autonomy. We also emphasise two non-explicit ways of giving consent: implied and opt-out consent. (...) We then discuss challenges and opportunities for obtaining consent in labour and birth, given its unique position in medicine.We argue that consent for procedures in labour is always necessary, but this consent does not always have to be fully informed or explicit. We recommend an individualised approach where the antenatal period is used to exchange information and explore values and preferences with respect to the relevant procedures. Explicit consent should always be sought at the point of intervening, unless women antenatally insist otherwise. We caution against implied consent. However, if a woman does not give a conclusive response during labour and the stakes are high, care providers can move to clearly communicated opt-out consent. Our discussion is focused on episiotomies, but also provides a useful starting point for addressing the ethics of consent for other procedures during labour, as well as general time-critical medical procedures.
