Strong relationships have been hypothesized between the timing of marriage and the familial environment of the couple. Sociologists have identified various mechanisms via which the age at marriage in the parental generation might be related to the age at marriage of the children. In our paper we study this relationship for historical populations. We use a dataset consisting of several hundreds of thousands of marriages contracted in three of the 11 Dutch provinces between 1812 and 1922. We identified the generational (...) links between the brides, grooms, their parents, and grandparents. We studied (a) whether there is a relationship between ages at marriage of (grandfathers) fathers and sons, and ages at marriage of (grandmothers) mothers and daughters and (b) whether this relationship might be explained by social class. We find evidence for a clear effect of the family on age at marriage and substantial intergenerational transmission. The impact that the family of origin has on age at entry into marriage can partly be attributed to social class. We also observed positive effects of grandparents’ age at marriage on their offspring’s age at marriage. (shrink)

BackgroundWith advances in sequencing technologies, increasing numbers of people are being informed about a genetic disease identified in their family. In current practice, probands are asked to inform at-risk relatives about the diagnosis. However, previous research has shown that relatives are sometimes not informed due to barriers such as family conflicts. Research on family communication in genetic diseases aims to explore the difficulties encountered in informing relatives and to identify ways to support probands in this.Main bodyResearch on family communication may (...) also reveal that participants did not inform their relatives about the risk of a serious genetic condition, even when preventive and treatment options are available. Researchers may then face a dilemma: Do they need to warn at-risk relatives about the finding? Or do they keep silent due to prior confidentiality agreements with study participants?ConclusionsWe believe that the absolute confidence promised to research participants outweighs the interests of their relatives, even though it can be claimed that relatives at risk of a genetic disease do, in principle, have a right to know information collected about their health. Not respecting confidentiality agreements could cause distrust between researchers and research participants and possibly harm the relationship between probands and relatives. Relatives' health interests can still be taken into account without jeopardizing participant trust, by considering alternative scenarios, including sharing general study findings on the barriers participants experience with their healthcare professionals and by offering participants psychosocial support for family communication.

In an effort to inform the discussion surrounding existential risks from AI, we formulate Extinction-level Goodhart’s Law as “Virtually any goal specification, pursued to the extreme, will result in the extinction of humanity”, and we aim to understand which formal models are suitable for investigating this hypothesis. Note that we remain agnostic as to whether Extinction-level Goodhart’s Law holds or not. As our key contribution, we identify a set of conditions that are necessary for a model that aims to be (...) informative for evaluating specific arguments for Extinction-level Goodhart’s Law. Since each of the conditions seems to significantly contribute to the complexity of the resulting model, formally evaluating the hypothesis might be exceedingly difficult. This raises the possibility that whether the risk of extinction from artificial intelligence is real or not, the underlying dynamics might be invisible to current scientific methods. (shrink)

This paper motivates institutional epistemic trust as an important ethical consideration informing the responsible development and implementation of artificial intelligence (AI) technologies (or AI-inclusivity) in healthcare. Drawing on recent literature on epistemic trust and public trust in science, we start by examining the conditions under which we can have institutional epistemic trust in AI-inclusive healthcare systems and their members as providers of medical information and advice. In particular, we discuss that institutional epistemic trust in AI-inclusive healthcare depends, in part, on (...) the reliability of AI-inclusive medical practices and programs, its knowledge and understanding among different stakeholders involved, its effect on epistemic and communicative duties and burdens on medical professionals and, finally, its interaction and alignment with the public’s ethical values and interests as well as background sociopolitical conditions against which AI-inclusive healthcare systems are embedded. To assess the applicability of these conditions, we explore a recent proposal for AI-inclusivity within the Dutch Newborn Screening Program. In doing so, we illustrate the importance, scope, and potential challenges of fostering and maintaining institutional epistemic trust in a context where generating, assessing, and providing reliable and timely screening results for genetic risk is of high priority. Finally, to motivate the general relevance of our discussion and case study, we end with suggestions for strategies, interventions, and measures for AI-inclusivity in healthcare more widely.

A letter written by Christiaan Huygens to David Gregory is published here for the first time. After an introduction about the contacts between the two correspondents, an annotated English translation of the letter is given. The letter forms part of the wider correspondence about the ‘new calculus’, in which L'Hospital and Leibniz also participated, and gives some new evidence about Huygens's ambivalent attitude towards the new developments. Therefore, two mathematical passages in the letter are discussed separately. An appendix contains (...) the original Latin text. (shrink)

The existence of various physical phenomena stems from the concept called asymptotic emergence, that is, they seem to be exclusively reserved for certain limiting theories. Important examples are spontaneous symmetry breaking (SSB) and phase transitions: these would only occur in the classical or thermodynamic limit of underlying finite quantum systems, since for finite quantum systems, due to the uniqueness of the relevant states, such phenomena are excluded by Theory. In Nature, however, finite quantum systems describing real materials clearly exhibit such (...) effects. In this paper we discuss these apparently “paradoxical” phenomena and outline various ideas and mechanisms that encompass both theory and reality, from physical and mathematical points of view.

Philosophy & Social Criticism, Volume 48, Issue 6, Page 904-933, July 2022. In this article, I reconstruct Étienne Balibar’s work against the background of the debate on modern universal citizenship. I argue that universal citizenship is neither fundamentally emancipatory nor fundamentally oppressive but is rather both. In order to defend this position, I build on Balibar’s concept of the “citizen subject.” First, I parse this concept, showing how it allows us to think about the contradictions of modern universal citizenship. In (...) the second section, I elucidate its temporal logic and show how it undermines the telos of modern universal citizenship. In sections three to five, I show how citizenship’s universalism clarifies both its oppressive and its emancipatory thrust. The dialectic of universal citizenship, I argue, unfolds as a conflict between and within political universals. In the conclusion, I will tie up these different strands and end with some reflections on the conditions of possibility of this dialectic. (shrink)

This article’s guiding thesis is that the theory of radical democratic citizenship is built on a tension between a radical, conflictual element and a democratic element. As radical democrats, these philosophers point to the intimate relation between conflict and both emancipation and democracy. But as radical democrats, they also propose different methods that prevent conflict from breaking up the polis—the common ground that makes democratic conflict possible. I look at two radical democrats’ way of dealing with this tension: Chantal Mouffe (...) and Étienne Balibar. My claim is that the former ends up overemphasising the danger of division in her later democratic works and is therefore unable to account for more intense forms of democratic resistance (such as riots). In the work of Balibar, however, we find a way of dealing with this tension. (shrink)

In response to critiques of rights as moralistic and depoliticising, a literature on the political nature and contestability of rights has emerged. In this view, rights are not merely formal, liberal and moralistic imperatives, but can also be invoked by the excluded in a struggle against domination. This article examines the limits to this practice of rights-claiming and its implication in forms of domination. It does this by returning to Marx’s blueprint for the critique of subjective rights. This engagement with (...) Marx will, however, take a particular form. I will read Marx first through the eyes of Claude Lefort and thereafter against Lefort. The latter’s critique of Marx still constitutes the strongest case against the dismissal of subjective rights. Introducing a reading of Lefort into the argument allows us to discover what is dead and what is well alive in the Marxist theory of rights. What is dead, I will argue, is Marx’s early conception of subjective rights as ideology and illusion. However, the more mature Marx developed a theory and critique of the legal form that is able to explain why the politics of rights—despite its undeniable advances—has not been able to overcome certain forms of domination.

The article engages Bakhtin’s corpus with Nietzschean ideas in order to draw out critical resources for the social theory of ‘community’. It begins by considering both thinkers’ debt to neo-Kantianism, and proceeds to relate the ‘will to power’ to Bakhtin’s early intersubjective phenomenology of intentional acts. This interpretation is then extended to Bakhtin’s conception of art, where aesthetics stands in tensile relation to ethics in the exercise of authorial will. Bakhtin’s later work might be seen as elaborating more complex terms (...) for describing will and event, now as composite embodiments of multiple intentions within art, discourse and language, thus suggesting a novel approach to ‘communality’ in modern social life.

The objective of this doctoral dissertation is to interpret the explanation of akrasia that the Dutch philosopher Benedictus Spinoza (1632-1677) gives in his work The Ethics. One is said to act acratically when one intentionally performs an action that one judges to be worse than another action which one believes one might perform instead. In order to interpret Spinoza’s explanation of akrasia, a large part of this dissertation investigates Spinoza’s theory of emotion. The first chapter is introductory and outlines Spinoza’s (...) categorisation of mental states and his conception of the relation between the mind and the body. The second chapter deals with Spinoza’s epistemology and the relation between cognitive mental states and states of the brain. The third chapter argues that Spinoza holds that emotions are non-cognitive mental states that are caused by cognitive mental states. The fourth chapter interprets Spinoza’s discussion of the emotions of Joy and Sadness insofar as they are mental states. The fifth chapter suggests that when Spinoza says that the power of our body is increased or decreased when we are joyful or sad, he means that when we are joyful or sad then, at the same time, our heart and perhaps the organs of our digestive system are affected in such a way that our bodily health is increased or decreased. The sixth chapter points to three problems that concern Spinoza’s definitions of the psychophysical states of pleasure, pain, cheerfulness and melancholy, and offers slightly altered definitions of these states. The seventh chapter interprets the various aspects of Spinoza’s conception of the emotion of Desire, both insofar as it is a state of the mind and insofar it is a state of the body, as well as the relation between the emotion of Desire and man’s striving for self-preservation. The eighth chapter discusses what Spinoza writes on the strength of emotions and the way in which we make value judgments in order to finally interpret why it is, according to Spinoza, that ‘we so often see the better for ourselves but follow the worse’.

Het verhaal van de natuurkunde is ook een persoonlijk verhaal, want achter de feiten gaan altijd mensen schuil. Van Einstein, die Beethoven op zijn viool probeert te spelen, tot Van Swinden, die jarenlang in het planetarium in Franeker werkt. Cees Andriesse, die 'Titan kan niet slapen' schreef, een biografie over Christiaan Huygens, heeft veel gevoel voor deze verhalen. In deze nieuwe geschiedenis van de natuurkunde wordt dan ook ruim aandacht besteed aan de zoektocht en wederwaardigheden van grote figuren, maar (...) ook van collega's uit de tijd dat Andriesse in Groningen werkte. De wetenschap draait om onmiskenbare relaties tussen harde feiten; die gaan spreken onder de pen van Andriesse, die oog heeft voor de ontdekkers en zichtbaar maakt hoe zijn eigen begrip is ontstaan. Het is hem niet te doen om de mechanisering van de natuurkunde, maar om de historisering daarvan. Dit boek biedt een nieuw perspectief op grote ontdekkingen, waarbij zowel God, als literatuur als psychologie een rol spelen. (shrink)

Beneficence is a foundational ethical principle in medicine. To provide benefit to a patient is to promote and protect the patient’s wellbeing, to promote the patient’s interests. But there are different conceptions of wellbeing, emphasizing different values. These conceptions of wellbeing are contrary to one another and give rise to dissimilar ideas of what it means to benefit a patient. This makes the concept of beneficence ambiguous: is a benefit related to the patient’s goals and wishes, or is it a (...) matter of objective criteria that constitute wellbeing? This paper suggests a unified conception of wellbeing for use in medicine to determine what counts as a benefit. Two components of wellbeing are identified: (1) objective functioning/health and (2) the patient’s view of her own good. The paper explores how to apply, balance, and weigh these components in clinical situations to determine what counts as a benefit to a patient. (shrink)

For many years the prevailing paradigm for medical decision making for children has been the best interest standard. Recently, some authors have proposed that Mill’s “harm principle” should be used to mediate or to replace the best interest standard. This article critically examines the harm principle movement and identifies serious defects within the project of using Mill’s harm principle for medical decision making for children. While the harm principle proponents successfully highlight some difficulties in present-day use of the best interest (...) standard, the use of the harm principle suffers substantial normative and conceptual problems. A medical decision-making framework for children is suggested, grounded in the four principles. It draws on the best interest standard, incorporates concepts of harm, and provides two questions that can act as guide and limit in medical decision making for children. (shrink)

In this paper, we criticize the current focus of the bio-based economy (BBE) on efficiency and control and demonstrate the contradictions that this causes. We elucidate these tensions by comparing the BBE to alternative conceptions of economy that emphasise the relevance of both the human condition and unfathomable nature in the macro ecological transition project. From Emmanuel Levinas’s philosophy, we take and extrapolate two major concepts—il y a and enjoyment—that help to re-evaluate the status of both nature and the human (...) subject involved in environmental instability. From this analysis, we evaluate current economic practice in close relation to the deteriorating environment to contribute to a conception of an economy that is truly based on principles of the biosphere. We conclude that humankind and nature are notions that must be always considered in this encompassing and topical effort and explain how they have been fundamentally overlooked in current thought on the bio-based and circular economy.

This article examines an argument which may negatively influence measles vaccination uptake. According to the argument, an individual child in a highly vaccinated society may be better off by being non-vaccinated; the child does not risk vaccine adverse effects and is protected against measles through herd immunity. Firstly, the conclusion of the argument is challenged by showing that herd immunity’s protection is unreliable and inferior to vaccination. Secondly, the logic of the argument is challenged by showing that the argument is (...) inherently self-defeating and therefore logically inconsistent. In practice the argument cannot be used to protect children against measles. Measles vaccination is undoubtedly best for children, even in highly vaccinated societies. Only if a medical contraindication to vaccination exists should vaccination be waived in favour of reliance on herd immunity. This places obligations on those who stand in care relationships with the child: parents, healthcare providers, and the state. (shrink)

In the Netherlands, current policy opinion emphasizes demand-driven health care. Central to this model is the view, advocated by some Dutch health policy makers, that patients should be encouraged to be aware of and make use of health quality and health outcomes information in making personal health care provider choices. The success of the new health care system in the Netherlands is premised on this being the case. After a literature review and description of the new Dutch health care system, (...) the adequacy of this demand-driven health policy is tested. The data from a July 2005, self-administered questionnaire survey of 409 patients (response rate of 94%) as to how they choose a hospital are presented. Results indicate that most patients did not choose by actively employing available quality and outcome information. They were, rather, referred by their general practitioner. Hospital choice is highly related to the importance a patient attaches to his or her physician’s opinion about a hospital. Some patients indicated that their hospital choice was affected by the reputation of the hospital, by the distance they lived from the hospital, etc. but physician’s advice was, by far, the most important factor. Policy consequences are important; the assumptions underlying the demand-driven model of patient health provider choice are inadequate to explain the pattern of observed responses. An alternative, more adequate model is required, one that takes into account the patient’s confidence in physician referral and advice. (shrink)

This paper defends four lines of argument that establish an ethical obligation for clinicians to be vaccinated against COVID-19. They are: (1) The obligation to protect patients against COVID-19 spread; (2) The obligation to maintain professional competence and remain available for patients; (3) Clinicians’ role and place in society in relation to COVID-19; (4) The obligation to encourage societal vaccination uptake. These arguments stand up well against potential objections and provide a compelling case to consider acceptance of COVID-19 vaccination a (...) duty for all clinicians. This duty brings with it the implication that vaccine refusal amounts to a dereliction of the professional’s ethical obligations, which means such clinicians should be subject to disciplinary action. Furthermore, this duty provides grounding for mandatory vaccination policies for clinicians. (shrink)

The 2005 UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions provides an international policy lens for analysing broad debates on issues of cultural globalization and development.

The broad gamut of theories, methods, and evidence collected (...) by the editors outlines UNESCO's accomplishments, shortcomings, and future policy prospects. This edited collection has a clear message: The Convention is a useful and important instrument in the debate on cultural diversity, but not broad enough or sufficient to confront major challenges concerning human rights, sustainability, and cultural diversity as a whole.

Bernard Lonergan argued that a Thomist theory of intellect must begin with advertence to the act of understanding. He distinguished his cognitional theory from a conceptualism that neglects the experience of insight and reflection on it. Early in his career, he explained how the conceptualist approach misinterprets Aquinas and creates problems for the metaphysics of rational psychology. This article explains Lonergan’s position and illustrates the conceptualist alternative by analysing Joseph Owens’s view of cognition. By explaining the metaphysical differences between Lonergan’s (...) and Owens’s opposing views of human knowing in relation to their distinctive readings of Aquinas, this article contributes to a more accurate reading of Aquinas on the act of understanding.

This essay surveys the main objections to aesthetic hedonism, the view that aesthetic value is reducible to the value of aesthetic pleasure or experience. Hedonism is the dominant view of aesthetic value, but a spate of recent criticisms has drawn its accuracy into question. I introduce some distinctions crucial to the criticisms, before using the bulk of the essay to identify and review six major lines of argument that hedonism's critics have employed against it. Whether or not these arguments suffice (...) to refute hedonism decisively, I argue that its privileged status, as the sole contender in aesthetic value theory, is detrimental to downstream research on aesthetic phenomena. The essay concludes with an overview of current work and promising avenues of inquiry into non-hedonic alternatives. (shrink)

In this article , I first engage in some conceptual clarification of what the words "imagine," "imagining," and "imagination" can mean. Each has a constructive sense, an attitudinal sense, and an imagistic sense. Keeping the senses straight in the course of cognitive theorizing is important for both psychology and philosophy. I then discuss the roles that perceptual memories, beliefs, and genre truth attitudes play in constructive imagination, or the capacity to generate novel representations that go well beyond what's prompted by (...) one's immediate environment.

The prospective robots in healthcare intended to be included within the conclave of the nurse-patient relationship—what I refer to as care robots—require rigorous ethical reflection to ensure their design and introduction do not impede the promotion of values and the dignity of patients at such a vulnerable and sensitive time in their lives. The ethical evaluation of care robots requires insight into the values at stake in the healthcare tradition. What’s more, given the stage of their development and lack of (...) standards provided by the International Organization for Standardization to guide their development, ethics ought to be included into the design process of such robots. The manner in which this may be accomplished, as presented here, uses the blueprint of the Value-sensitive design approach as a means for creating a framework tailored to care contexts. Using care values as the foundational values to be integrated into a technology and using the elements in care, from the care ethics perspective, as the normative criteria, the resulting approach may be referred to as care centered value-sensitive design. The framework proposed here allows for the ethical evaluation of care robots both retrospectively and prospectively. By evaluating care robots in this way, we may ultimately ask what kind of care we, as a society, want to provide in the future. (shrink)

This essay argues that there are theoretical benefits to keeping distinct—more pervasively than the literature has done so far—the psychological states of imagining that p versus believing that in-the-story p, when it comes to cognition of fiction and other forms of narrative. Positing both in the minds of a story’s audience helps explain the full range of reactions characteristic of story consumption. This distinction also has interesting conceptual and explanatory dimensions that haven’t been carefully observed, and the two mental state (...) types make distinct contributions to generating emotional responses to stories. Finally, the differences between the mental states illuminate how a given story can be both shared with others and at the same time experienced as personal. (shrink)

What makes paternalism wrong? I give an indirect answer to that question by challenging a recent trend in the literature that I call the exclusionary strategy. The exclusionary strategy aims to show how some feature of the paternalizee’s normative situation morally excludes acting for the paternalizee’s well-being. This moral exclusion consists either in ruling out the reasons for which a paternalizer may act or in changes to the right-making status of the reasons that (would) justify paternalistic intervention. I argue that (...) both versions of the exclusionary strategy fail to explain the wrongness of paternalism and that they struggle to accommodate the mainstream view that paternalism is only pro tanto wrong. Their failure consists either in being implausibly strong expressions of antipaternalism or in struggling to spell out the scope of exclusion in an uncomplicated way. After discouraging this exclusionary strategy, I suggest we can capture what is appealing about it—as well as avoiding its pitfalls—by sketching a philosophical model in which we compare the weights of reasons for and against paternalistically interfering. To precisify this sketch, I introduce some conceptual tools from the literature on practical reasoning—in particular, the concept of modifiers—and suggest that these tools offer a better starting point for figuring out what makes paternalism (pro tanto) wrong.

Generally, we want certain ethical claims to be unconditionally true. One such claim is “Apartheid was unjust”. In this paper, I discuss a group of South African post-structuralist philosophers who call their view Critical Complexity (CC). Because of post-structuralism’s radical contextualism, CCists can only claim that things are ‘as if’ Apartheid was unjust. They cannot claim that Apartheid was unconditionally unjust. Many will find this unsatisfying. I argue that a naturalised or Darwinian notion of rationality can help CCists (and perhaps (...) post-structuralists in general) in this regard. This kind of rationality is what has come to be known as embodied rationality. We employ embodied rationality when navigating the ecological and social domains. It has, though, been co-opted for navigating the ethical domain. We can, then, claim that Apartheid was unconditionally unjust because it is embodied rational to do so. This does not involve embracing the kind of Cartesian rationality that CCists rightly reject. (shrink)

The central question of the peer disagreement debate is: what should you believe about the disputed proposition if you have good reason to believe that an epistemic peer disagrees with you? This article shows that this question is ambiguous between evidential support (or propositional justification) and well-groundedness (or doxastic justification). The discussion focuses on conciliatory views, according to which peer disagreements require you to significantly revise your view or to suspend judgment. The article argues that for a wide range of (...) conceptions of evidential support, conciliatory views are false if they are understood entirely in terms of evidential support. Alternative conceptions of evidential support face some serious difficulties. These arguments speak against conciliationism, but the article then goes on to defend a conciliatory view about well-grounded belief: when you believe p, and you have good reason to believe that your epistemic peer disagrees with you, you are not justified in believing p because that belief is no longer well grounded. This picture of the epistemology of peer disagreement offers a reconciliation of some of the main competing views in the literature: conciliationism is true when we look at well-grounded belief, but a nonconciliatory view like Thomas Kelly's “total evidence view” is correct when we look at peer disagreement exclusively in terms of evidential support.

According to the traditional view in the philosophy of logic facts of logic bear normative authority regarding how one ought to reason. Usually this is to mean that the relation of logical consequence between statements has some special relevance for how one’s beliefs should cohere. However, as I will argue in this article, this is just one way in which logic is normative for reasoning. For one thing, belief is not the only kind of mental state involved in reasoning. Besides (...) adopting and revising beliefs, rational agents pose and resolve questions. For another thing, the consequence relation of classical logic can be conservatively extended such that it includes logical relations between questions as well. Therefore, there is an argument to be made that not only the inference of new beliefs from extant beliefs but also the process of raising additional questions falls under the normative authority of logic. Accordingly, a nuanced account of the normativity of logic presents itself, which convincingly deals with problems such as clutter-avoidance and the paradox of the preface. (shrink)

The story of how Perrin’s experimental work established the reality of atoms and molecules has been a staple in (realist) philosophy of science writings (Wesley Salmon, Clark Glymour, Peter Achinstein, Penelope Maddy, …).
