Ian Rumfitt (2000) developed a bilateralist account of logic in which the meaning of the connectives is given by conditions on asserted and rejected sentences. An additional set of inference rules, the coordination principles, determines the interaction of assertion and rejection. Fernando Ferreira (2008) found this account defective, as Rumfitt must state the coordination principles for arbitrary complex sentences. Rumfitt (2008) has a reply, but we argue that the problem runs deeper than he acknowledges and is in fact related to (...) the challenge of establishing proof-theoretic harmony. We motivate a distinctively bilateral criterion for harmony and show how the bilateralist can meet it. This also resolves Ferreira's complaint. (shrink)

The papers in Richard Vallée's Words and Contents span twenty-one years. The author navigates the discovery and exploration of different expressions and perspectives on language in this volume. Beginning with referring expressions and later addressing context sensitivity, the book examines how specific words contribute to the contents of utterances and the philosophical issues that surround them.

In a recent paper del Valle-Inclan and Schlöder argue that bilateral calculi call for their own notion of proof-theoretic harmony, distinct from the usual (or ‘unilateral’) ones. They then put forward a specifically bilateral criterion of harmony, and present a harmonious bilateral calculus for classical logic. In this paper, I show how del Valle-Inclan and Schlöder’s criterion of harmony suggests a notion of normal form for bilateral systems, and prove normalisation for two (harmonious) bilateral calculi for classical logic, (...) HB1 and HB2. The resulting normal derivations have the usual desirable features, like the separation and subformula properties. HB1-normal form turns out to be strictly stronger that the notion of normal form proposed by Nils Kürbis, and HB2-normal form is neither stronger nor weaker than a similar proposal by Marcello D’Agostino, Dov Gabbay, and Sanjay Modgyl.

Targeting high-risk populations for public health interventions is a classic tool of public health promotion programs. This practice becomes thornier when racial groups are identified as the at-risk populations. I present the particular ethical and epistemic challenges that arise when there are low-risk subpopulations within racial groups that have been identified as high-risk for a particular health concern. I focus on two examples. The black immigrant population does not have the same hypertension risk as US-born African Americans. Similarly, Finnish descendants (...) have a far lower rate of cystic fibrosis than other Caucasians. In both cases the exceptional nature of these subpopulations has been largely ignored by the designers of important public health efforts, including the recent US government dietary recommendations. I argue that amending the publicly-disseminated risk information to acknowledge these exceptions would be desirable for several reasons. First, recognizing low-risk subpopulations would allow more efficient use of limited resources. Communicating this valuable information to the subpopulations would also promote truth-telling. Finally, presenting a more nuanced empirically-supported representation of which groups are at known risk of diseases (not focusing on mere racial categories) would combat harmful biological race essentialist views held by the public.

In the scenario of growing polarization of promises and dangers that surround artificial intelligence (AI), how to introduce responsible AI and robotics in healthcare? In this paper, we develop an ethical–political approach to introduce democratic mechanisms to technological development, what we call “Caring in the In-Between”. Focusing on the multiple possibilities for action that emerge in the realm of uncertainty, we propose an ethical and responsible framework focused on care actions in between fears and hopes. Using the theoretical perspective of (...) Science and Technology Studies and empirical research, “Caring in the In-Between” is based on three movements: the first is a change of focus from the world of promises and dangers to the world of uncertainties; the second is a conceptual shift from assuming a relationship with robotics based on a Human–Robot Interaction to another focused on the network in which the robot is embedded (the “Robot Embedded in a Network”); and the last is an ethical shift from a general normative framework to a discussion on the context of use. Based on these suggestions, “Caring in the In-Between” implies institutional challenges, as well as new practices in healthcare systems. It is articulated around three simultaneous processes, each of them related to practical actions in the “in-between” dimensions considered: monitoring relations and caring processes, through public engagement and institutional changes; including concerns and priorities of stakeholders, with the organization of participatory processes and alternative forms of representation; and making fears and hopes commensurable, through the choice of progressive and reversible actions.

BackgroundHIV prevention research in resource-limited countries is associated with a variety of ethical dilemmas. Key amongst these is the question of what constitutes an appropriate standard of health care (SoC) for participants in HIV prevention trials. This paper describes a community-focused approach to develop a locally-appropriate SoC in the context of a phase III vaginal microbicide trial in Mwanza City, northwest Tanzania.MethodsA mobile community-based sexual and reproductive health service for women working as informal food vendors or in traditional and modern (...) bars, restaurants, hotels and guesthouses has been established in 10 city wards. Wards were divided into geographical clusters and community representatives elected at cluster and ward level. A city-level Community Advisory Committee (CAC) with representatives from each ward has been established. Workshops and community meetings at ward and city-level have explored project-related concerns using tools adapted from participatory learning and action techniques e.g. chapati diagrams, pair-wise ranking. Secondary stakeholders representing local public-sector and non-governmental health and social care providers have formed a trial Stakeholders' Advisory Group (SAG), which includes two CAC representatives.ResultsKey recommendations from participatory community workshops, CAC and SAG meetings conducted in the first year of the trial relate to the quality and range of clinic services provided at study clinics as well as broader standard of care issues. Recommendations have included streamlining clinic services to reduce waiting times, expanding services to include the children and spouses of participants and providing care for common local conditions such as malaria. Participants, community representatives and stakeholders felt there was an ethical obligation to ensure effective access to antiretroviral drugs and to provide supportive community-based care for women identified as HIV positive during the trial. This obligation includes ensuring sustainable, post-trial access to these services. Post-trial access to an effective vaginal microbicide was also felt to be a moral imperative.ConclusionParticipatory methodologies enabled effective partnerships between researchers, participant representatives and community stakeholders to be developed and facilitated local dialogue and consensus on what constitutes a locally-appropriate standard of care in the context of a vaginal microbicide trial in this setting.Trial registrationCurrent Controlled Trials ISRCTN64716212.

According to inferentialists the meaning of logical vocabulary is given by the rules of inference governing its use. In response to a challenge posed by Arthur Prior, inferentialists have typically argued that not all sets of rules can define a connective. The project of determining which sets of rules are acceptable definitions has come to be known as the project of finding a criterion of proof-theoretic harmony. One of the best-known proposals is Neil Tennant’s. His criterion of harmony relies on (...) the notions of the strength of a proposition and the strength of a rule. In this note, I argue that Tennant’s appeal to the notion of the strength of a rule gives rise to problems that make his account unsustainable. I also argue that the sort of consideration that gets Tennant into trouble applies, more generally, to other so-called ‘local’ accounts of harmony, and casts doubts on the idea that we can uniquely determine the harmonious counterpart of a given set of rules.

Recommender Systems (RecSys) have been around since the early days of the Internet, helping users navigate the vast ocean of information and the increasingly available options that have been available for us ever since. The range of tasks for which one could use a RecSys is expanding as the technical capabilities grow, with the disruption of Machine Learning representing a tipping point in this domain, as in many others. However, the increase of the technical capabilities of AI-powered RecSys did not (...) come with a thorough consideration of their ethical implications and, despite being a well-established technical domain, the potential impacts of RecSys on their users are still under-assessed. This paper aims at filling this gap in regards to one of the main impacts of RecSys: personal autonomy. We first describe how technology can affect human values and a suitable methodology to identify these effects and mitigate potential harms: Value Sensitive Design (VSD). We use VSD to carry out a conceptual investigation of personal autonomy in the context of a generic RecSys and draw on a nuanced account of procedural autonomy to focus on two components: competence and authenticity. We provide the results of our inquiry as a value hierarchy and apply it to the design of a speculative RecSys as an example. (shrink)

A growing body of literature has engaged with mass incarceration as a public health problem. This article reviews some of that literature, illustrating why and how bioethicists can and should engage with the problem of mass incarceration as a remediable cause of health inequities. “Mass incarceration” refers to a phenomenon that emerged in the United States fifty years ago: imprisoning a vastly larger proportion of the population than peer countries do, with a greatly disproportionate number of incarcerated people being members (...) of marginalized racial and ethnic groups. Bioethicists have long engaged with questions of health justice for incarcerated people, including consent issues for those participating in research and access to health care. This article provides an overview of the individual and public health impacts of mass incarceration. The article argues that mass incarceration is a bioethics issue that should be addressed in medical education, identifies opportunities for bioethicists to guide hospitals’ interactions with law enforcement officials, and calls on bioethicists to be in conversation with medical and nursing students and health care professionals about these groups’ advocacy efforts concerning structural racism, police violence, and mass incarceration.

In this paper, we explore how the definition of life takes on an essential character in the ethical debates around health technologies, with life thus being manufactured in the tensions and conflicts around the use of such artefacts and devices. We introduce concepts from science and technology studies (STS) to approach bioethics, overcoming the dualistic conception that separates the natural and the technological and questioning the dominant rationality that divides life into dualities. Drawing on two research projects in which we (...) have been involved in recent years, one regarding biobanks and the other regarding social care robots, we explore how the ethical discussions about biobanks and robots imply particular notions of life. We argue that the contemporary epistemic category of life is a manufactured life in which various rationalities coexist: one rationality based on a separation between the technological and the human, focused on pragmatism and functionalities that tend towards a dualized notion of life divided into qualified and non-qualified life, and another rationality based on a non-essentialist ontology, focused on the mediating role of health technologies, that entails a distributed life appearing as a precarious effect of a network. Each of these rationalities allows the emergence of different issues and ethical concerns, thus enriching the bioethical debate. (shrink)

Professionals in environmental fields engage with complex problems that involve stakeholders with different values, different forms of knowledge, and contentious decisions. There is increasing recognition of the need to train graduate students in interdisciplinary environmental science programs in these issues, which we refer to as “social ethics.” A literature review revealed topics and skills that should be included in such training, as well as potential challenges and barriers. From this review, we developed an online survey, which we administered to faculty (...) from 81 United States colleges and universities offering IESPs. Respondents overwhelmingly agreed that IESPs should address values in applying science to policy and management decisions. They also agreed that programs should engage students with issues related to norms of scientific practice. Agreement was slightly less strong that IESPs should train students in skills related to managing value conflicts among different stakeholders. The primary challenges to incorporating social ethics into the curriculum were related to the lack of materials and expertise for delivery, though challenges such as ethics being marginalized in relation to environmental science content were also prominent. Challenges related to students’ interest in ethics were considered less problematic. Respondents believed that social ethics are most effectively delivered when incorporated into existing courses, and they preferred case studies or problem-based learning for delivery. Student competence is generally not assessed, and respondents recognized a need for both curricular materials and assessment tools. (shrink)

The case of Merleau-Ponty’s phenomenology is based on the weaving between experience and expression of experience. From this point of view, the article examines Merleau-Ponty’s reflections on children’s drawing and on modern art. Bot try to get back the raw perception of the world - beyond the idealisations of perspective art and of geometry - and rediscover the expressive and symbolic dynamics in our body experience.

Há duas décadas celebramos o ‘descobrimento’ do Brasil. O quão distantes estamos, hoje, desta realidade? E o quão perto estamos de nos entender brasileiros? Com inspiração em trabalhos de artistas contemporâneos em diálogo com a teoria do caráter destrutivo de Walter Benjamin – onde faz-se destroços do existente menos pelas ruínas que pelos caminhos que surgem através delas (1973, p. 14) –; o presente artigo propõe pensarmos no que é preciso destruir da história oficial, uma história que ainda se pauta (...) na invasão e colonização portuguesa, para abrir caminhos para uma nova história milenar, de resistência e de festa. Uma narrativa que devolva, por fim, o amor à história brasileira. (shrink)

“Nobody had ever seen anything like this before.”“Nobody would have ever thought a thing like this could have happened.”There is a lot at stake in the current and forthcoming debates over what/why/how the COVID-19 pandemic’s effects on the US were unpredictable. These debates are crucial to both our assessments of backward-looking culpability and in the related but even more socially important task of guiding decisions about how to rebuild society after the pandemic subsides. The more we treat the harm as (...) unexpected—a fluke—the more we bolster the argument that no major structural changes need to be made to the US health system. I come to this question as one of...

Among the many applications of artificial intelligence (AI), virtual assistants are one of the tools most likely to grow in the future. The development of these systems may play an increasingly important role in many facets of our lives. Therefore, given their potential importance and present and future weight, it is worthwhile to analyze what kind of challenges they entail. In this chapter, we will provide an overview of the ethical aspects of artificial virtual assistants. First, we provide a conceptual (...) clarification of the term ‘virtual assistant’, including different types of interfaces and recommender systems. Second, we address three ethical issues related to the deployment of these systems: their effects on human agency and autonomy and the subsequent cognitive dependence they would generate; the human obsolescence that may cause a generalized extension of the dependence problem; and the invasions of privacy that virtual assistants may cause. Finally, we outline the debates about the use of virtual assistants to improve human moral decisions and some areas in which these systems can be applied. (shrink)

Since early in the Covid-19 pandemic, there have been wide disparities observed between different US racial groups’ rates of Covid-19 infections and deaths. This challenges physicians and patients to untangle what these race-associated risks mean for an individual patient. I argue that this task of providing individualized risk advice requires physicians to apply two skills: structural competency and epistemic humility.
