The “practice turn” in philosophy of science has strengthened the connections between philosophy and scientific practice. Apart from reinvigorating philosophy of science, this also increases the relevance of philosophical research for science, society, and science education. In this paper, we reflect on our extensive experience with teaching mandatory philosophy of science courses to science students from a range of programs at University of Copenhagen. We highlight some of the lessons we have learned in making philosophy of science “fit for teaching” (...) outside of philosophy circles by taking selected cases from the students’ own field as the starting point. We argue for adapting philosophy of science teaching to particular audiences of science students, and discuss the benefits of drawing on research within science education to inform curriculum and course design. This involves reconsidering teaching resources, assumptions about students, intended learning outcomes, and teaching formats. We also argue that to make philosophy of science relevant and engaging to science students, it is important to consider their potential career trajectories. By anticipating future contexts and situations in which methodological, conceptual, and ethical questions could be relevant, philosophy of science can demonstrate its value in the education of science students.

Many degree programs in science and engineering aim at enabling their students to perform interdisciplinary problem solving. In this paper we present three types of expertise that are involved in different ways in interdisciplinary problem solving. In doing so we shall first characterise two important epistemological challenges commonly faced in interdisciplinary problem solving, namely the communication challenge that arises from the use of different concepts within different scientific domains, and the integration challenge that arises from the differences between domain-specific epistemological (...) standards. Next, drawing on recent work on expertise developed within science studies, we characterize the interactional expertise that is a precondition for scientists to communicate across scientific domains, and the integrational expertise that is a precondition for scientists to be able to integrate cognitive resources originating in different domains. Finally, we shall analyse how different types of interdisciplinary problem solving sets different requirements for interactional and integrational expertise and discuss the implications for science and engineering programs in higher education.

Micro-phenomenology is an interview and analysis method for investigating subjective experience. As a research tool, it provides detailed descriptions of brief moments of any type of subjective experience and offers techniques for systematically comparing them. In this article, we use an auto-ethnographic approach to present and explore the method. The reader is invited to observe a dialogue between two authors that illustrates and comments on the planning, conducting and analysis of a pilot series of five micro-phenomenological interviews. All these interviews (...) asked experienced researchers of micro-phenomenology to browse their memories to identify one successful and one challenging instance of working with micro-phenomenology. The interview then focused on this reflective task to investigate whether applying the method to itself might reveal quality criteria. The article starts by presenting a shortened and edited version of the first of these interviews. Keeping the dialogue format, we then outline the micro-phenomenological analysis procedure by demonstrating its application to part of this data and corresponding passages of other interviews. We focus on one unexpected finding: interviewed researchers judge the quality of an interview in part based on a connection or contact between interviewer and interviewee. We discuss these results in the context of the means and intentions of the method and suggest avenues for future research. (shrink)

Little is known about the psychological processes that can explain how connectedness to nature evolves. From social psychology, we know that emotions play an essential role when connecting to others. In this article, we argue that social connectedness and connectedness to nature are underpinned by the same emotions. More specifically, we propose that social relational emotions are crucial to understanding the process, how humans connect to nature. Beside other emotions, kama muta (Sanskrit: being moved by love) might play a particular (...) crucial role when connecting to nature. Future research should address the consideration of social relational emotions in a range of areas when investigating the human-nature relationship. (shrink)

The paper critically discusses the moral view that neurotechnological behavioural treatment for criminal offenders should only be offered if it is in their best interests. First, I show that it is difficult to apply and assess the notion of the offender's best interests unless one has a clear idea of what ‘best interests’ means. Second, I argue that if one accepts that harmful punishment of offenders has a place in the criminal justice system, it seems inconsistent not to accept the (...) practice of offering offenders treatment even when the state will harm them in applying the treatment. Finally, leading penal theories like consequentialists and retributivists would not accept that the offender's best interests, at least in certain situations, impose a necessary condition for the treatment of an offender.

A novel theoretical framework for an embodied, non-representational approach to language that extends and deepens enactive theory, bridging the gap between sensorimotor skills and language. -/- Linguistic Bodies offers a fully embodied and fully social treatment of human language without positing mental representations. The authors present the first coherent, overarching theory that connects dynamical explanations of action and perception with language. Arguing from the assumption of a deep continuity between life and mind, they show that this continuity extends to language. (...) Expanding and deepening enactive theory, they offer a constitutive account of language and the co-emergent phenomena of personhood, reflexivity, social normativity, and ideality. Language, they argue, is not something we add to a range of existing cognitive capacities but a new way of being embodied. Each of us is a linguistic body in a community of other linguistic bodies. The book describes three distinct yet entangled kinds of human embodiment, organic, sensorimotor, and intersubjective; it traces the emergence of linguistic sensitivities and introduces the novel concept of linguistic bodies; and it explores the implications of living as linguistic bodies in perpetual becoming, applying the concept of linguistic bodies to questions of language acquisition, parenting, autism, grammar, symbol, narrative, and gesture, and to such ethical concerns as microaggression, institutional speech, and pedagogy.

This study examined the influence of two organizational context variables, codes of conduct and supervisor advice, on personnel decisions in an experimental simulation. Specifically, we studied personnel evaluations and decisions in a situation where codes of conduct conflict with supervisor advice. Past studies showed that supervisors’ advice to prefer ingroup over outgroup candidates leads to discriminatory personnel selection decisions. We extended this line of research by studying how codes of conduct and code enforcement may reduce this form of discrimination. Eighty (...) German managers evaluated and selected candidates from an applicant pool including Germans (ingroup members) and foreigners (outgroup members). Supervisor advice to prefer ingroup members lowered suitability ratings of outgroup members as well as their chances to be selected for an interview. Ethical codes of conduct referring to equal opportunities limited this form of discrimination, but only when codes were enforced by sanctions and integrated into organizational every-day practice. The implications of these findings for research and practice are discussed. (shrink)

Intuitions about contextualist cases such as Cohen’s airport case pose a problem for classical anti-skeptical versions of invariantism. Recently, Tim Black, Jessica Brown, and Patrick Rysiew have argued that the classical invariantist can respond by arguing that pragmatic aspects of epistemic discourse are responsible for the relevant problematic intuitions. This paper identifies the mechanisms of conversational implicature and impliciture as the basic sources of hope for this explanatory strategy. It then argues that neither of these sources provides the classical invariantist (...) with a convincing response to the airport case and its analogs. (shrink)

A ‘scientific worldview’ is commonly seen as contradictory to belief in supernatural forces, and there is little research on the supernatural beliefs of individuals who identify with science. In this article, we investigate the supernatural explanations of science-oriented individuals in domains of fundamental concern (suffering, death, and origins), and how supernatural causality is reconciled with belief in science. The open-ended responses of 387 Finns were analysed. The results show that science-oriented Finns endorsed both religion-related and more secular supernatural beliefs (such (...) as belief in evolution as a purposeful process). Following the coexistence model, science-oriented Finns applied synthetic and target-dependent reasoning. In addition, many who invoked supernatural explanations integrated supernatural causality with science. Two forms of integrated reasoning were found: 1) supernatural agency as the ultimate cause and scientific theory as the proximate cause, and 2) a similarity-based heuristic, as seen in afterlife beliefs appealing to the law of conservation of energy.

This article picks up from William James's pragmatism and metaphysics of experience, as expressed in his “radical empiricism,” and further develops this Jamesian pragmatist approach to uncertainty and ignorance by connecting it to phenomenological thought. The Jamesian pragmatist approach avoids both a “crude naturalism” and an “absolutist rationalism,” and allows for identification of intimations of the sacred in both scientific and religious practices—which all, in their respective ways, try to make sense of a complex world. Analogous to religious practices, emotion (...) and the metaphysics of experience play a central role in science, especially the emotion of wonder. Engaging in scientific or religious practices may create opportunities for individuals to realize that they are co-creators of the world in partnership with God, in full awareness of uncertainty and ignorance and filled with the emotion of wonder.

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

Pregnancy presents some interesting challenges for the philosophy of embodied cognition. Mother and fetus are generally considered to be passive during pregnancy, both individually and in their relation. In this paper, we use the enactive operational concepts of autonomy, agency, individuation, and participation to examine the relation between mother and fetus in utero. Based on biological, physiological, and phenomenological research, we explore the emergence of agentive capacities in embryo and fetus, as well as how maternal agency changes as pregnancy advances. (...) We show that qualitatively different kinds of agency have their beginnings already in utero, and to what extent fetal and maternal movement modulate affectivity and individuation in pregnancy. We thus propose that mother and fetus are both agents who participate in pregnancy. Pregnancy then emerges as a relational developmental organization that anchors and holds its developing participants. We end the paper with reflections on ethical implications of this proposal, and suggestions for future research. (shrink)

Anatomy texts are seen as authoritative sources for knowledge about natural sex differences. The concepts of a natural, biological sex and of a natural difference are, however, increasingly difficult to sustain. A growing number of scholars have pointed to the fact that `sex' as much as `gender' is a historical and social construction. This article examines how the multiple-edition anatomy textbook, Gray's Anatomy, has portrayed the sexed body and male/female differences during the course of its publication, 1858 to the present, (...) focusing on specific parts of the anatomy, namely the sex organs or `organs of generation', the pelvis, the skull and the brain. An analysis of textual descriptions and graphic illustrations reveals that the male body has been the stable norm or standard against which the female body has been compared and implicitly judged as underdeveloped, weak or faulty. Only rarely has the male body been compared with the female body. Reflecting long-standing views about sexual complementarity and natural differences between men and women, some comparisons emphasize the reproductive functioning of females or imply that females are intellectually inferior. It would appear that the discipline of anatomy has remained largely immune from broader public debates about sexual inequality and gender representations. (shrink)

Employers’ access to and use of criminal records as a selection mechanism in the labor market makes it far more difficult for ex-offenders to find jobs, especially regular, well-paid jobs, than those without criminal convictions. The paper asks whether there is anything morally problematic about this practice. The aims of the paper are twofold. First, arguments based on premises of wrongful discrimination against the current, commonest use of criminal records are critically discussed. It is argued that employers do not necessarily (...) engage in morally wrongful discrimination against job applicants when they use criminal records in recruitment screening. But it is also argued that ex-offenders who apply for jobs are subject to what can be called “structural and morally wrongful discrimination” when laws allow employers to request (or directly access) a job applicant’s full criminal record. Second, preliminary proposals on how criminal records can be used by employers in a way that avoids wrongful structural discrimination of ex-offenders will be presented and critically assessed. I suggest that it should be lawful for an employer to access an applicant’s criminal records only where there is a relevant and special match or link between the crime on the records and the job being applied for and the crime is serious. This proposal is defended against two objections, one based on concerns about crime prevention and the other based on the employer’s interest in knowing whom not to hire. (shrink)

Research biobanks are heterogeneous and exist to manage diverse biosample types with the goal of facilitating and serving biomedical discovery. The perspectives of biobank managers are reviewed, and the perspectives of two biobank directors, one with experience in institutional biobanks and the other with national cooperative group banks, are presented. Most research biobanks are not designed, nor do they have the resources, to return research results and incidental findings to participants or their families.

Genomic research results and incidental findings with health implications for a research participant are of potential interest not only to the participant, but also to the participant's family. Yet investigators lack guidance on return of results to relatives, including after the participant's death. In this paper, a national working group offers consensus analysis and recommendations, including an ethical framework to guide investigators in managing this challenging issue, before and after the participant's death.

The policy adopted by housing authorities of denying prospective tenants with a criminal record access to housing is an important barrier to ex-offenders seeking somewhere to live. The policy is legal, but are there any good reasons in favor of it when we know that having no, or limited, access to secure and affordable housing increases the probability of recidivism? The primary aim of this article is to critically discuss two central reasons that have been given for denying people with (...) criminal records access to housing: that doing so will prevent crime, and that the policy reduces fear of crime. We also try to evaluate an argument for the conclusion that current law, and the policies that follows wrongfully discriminate against people with criminal records. The general thrust of the article is that arguments for this practice turning on its crime preventive effect, and its role in reducing or preventing fear of crime, are unpersuasive. We then explained why, in our view, excluding ex-offenders from housing amounts to wrongful discrimination against them. Our analysis suggests that ex-offenders, apart from a few excemptions, ought to be allowed access to housing to the same extent as other people. (shrink)

In both philosophical and linguistic research, the explicit cancelability test is widely used to distinguish semantic contents from conversational implicatures. Assuming a straightforward relation between semantic content and explicit cancelability, a researcher might think that: if the proposition _p_ is expressed semantically by an utterance, then _p_ is not explicitly cancelable. In this paper, however, I argue for two amendments to this assumption. First, following Jerrold Sadock, I argue that the semantic content of an ambiguous utterance may be explicitly cancelable. (...) Against this widely accepted view, a recent paper by Arthur Sullivan argues that the ambiguity problem should be rejected. I respond to Sullivan’s arguments and argue that the ambiguity problem remains despite Sullivan’s objections. Second, I argue that there is also another type of case complicating the relation between semantic content and explicit cancelability. In some cases where an utterance of a sentence _s_ semantically expresses the proposition that _p_, certain resources that speakers have available for metalinguistic communication may be employed to make _p_ satisfy a sufficient condition for explicit cancelability, although _s_ is not ambiguous. These two weaknesses of the explicit cancelability test have important implications for its diagnostic use. (shrink)

Life history theory suggests that in risky and uncertain environments the optimal reproductive strategy is to reproduce early in order to maximize the probability of leaving any descendants at all. The fact that early menarche facilitates early reproduction provides an adaptationist rationale for our first two hypotheses: that women who experience more risky and uncertain environments early in life would have (1) earlier menarche and (2) earlier first births than women who experience less stress at an early age. Attachment theory (...) and research provide the rationale for our second two hypotheses: that the subjective early experience of risky and uncertain environments (insecurity) is (3) part of an evolved mechanism for entraining alternative reproductive strategies contingent on environmental risk and uncertainty and (4) reflected in expected lifespan. Evidence from our pilot study of 100 women attending antenatal clinics at a large metropolitan hospital is consistent with all four hypotheses: Women reporting more troubled family relations early in life had earlier menarche, earlier first birth, were more likely to identify with insecure adult attachment styles, and expected shorter lifespans. Multivariate analyses show that early stress directly affected age at menarche and first birth, affected adult attachment in interaction with expected lifespan, but had no effect on expected lifespan, where its original effect was taken over by interactions between age at menarche and adult attachment as well as age at first birth and adult attachment. We discuss our results in terms of the need to combine evolutionary and developmental perspectives and the relation between early stress in general and father absence in particular. (shrink)

Abstract.This paper is a sequel to my [7]. It focuses on the notion of natural number as introduced in section 11 of that paper with regard to forms of induction and recursive definitions. One point is that this notion of natural number is somewhat weaker than the classical one in so far as it is defined in terms of a weak implication. The other point is the lack of even a weak form of extensionality. As a main result of the (...) present paper it will turn out that the means provided in [7] are sufficient to account for an interpretation of primitive recursive arithmetic. (shrink)

According to recent news reports, developments in biotechnology promise to transform our bodies and our lives. Stem cell research and cloning research are reported to offer us the prospect of being able to grow `spare' body parts and to replace diseased or damaged tissue, implying that there are no natural limits to life, and that the body-machine may be endlessly repaired, and even replicated. The birth of a cloned sheep, Dolly, announced in February 1997, is seen as a milestone development (...) in this regard, suggesting that it is possible to defy `nature' by `turning back the biological clock'. While the development was heralded by many as pointing to new medical therapies, it also served to fuel widespread fears that the technology would soon be applied to cloning humans. This article explores how the news media `framed' issues on human cloning in the aftermath of the announcement of Dolly and thus may have heightened public concerns about its implications, particularly for `individuality' or `identity'. It draws on articles appearing in Australian newspapers, beginning with the initial stories on Dolly through to May 1999, when it was reported that Dolly had shown signs of premature ageing. The article highlights the role of the media in shaping public debate on biotechnology, particularly with regard to its impacts on the body, self and society. (shrink)

In this article several justifications of what I call ‘the claim from adoption’ are examined. The claim from adoption is that, instead of expending resources on bringing new children into the world using reproductive technology and then caring for these children, we ought to devote these resources to the adoption and care of existing destitute children.Arguments trading on the idea that resources should be directed to adoption instead of assisted reproduction because already existing people can benefit from such a use (...) of resources whereas we cannot benefit individuals by bringing them into existence are rejected. It is then argued that a utilitarian argument proposed by Christian Munthe that supports the claim from adoption in some situations should be rejected because the support it offers does not extend to certain situations in which it seems morally obvious that resources should be expended on adoption rather than assisted reproduction. A version of the Priority View improves upon Munthe’s utilitarianism by supporting the claim from adoption in the cases in which Munthe’s argument failed. Some allegedly counterintuitive implications of the Priority View are then discussed, and it is concluded that the Priority View is more plausible than utilitarianism.n a concluding section on policy issues it is argued that, even though the claim from adoption can be justified in a variety of situations, it does not follow that, in these situations, governments should direct resources away from assisted reproduction and towards adoption.

The purpose of this paper is to take a critical look at some of the assumptions and theories found in economics and management and discuss their implications for the practices found in the management of business and in public management. Two sets of assumptions are of interest here. First and foremost, the assumption that economic agents are only actuated by self-interest, accompanied by assumptions about the motivating effect of pecuniary incentives and assumptions about the regulation of behaviour through rules, controls (...) and sanctions; secondly, assumptions about “scientificness” and objectivity, accompanied by demands for mathematical formalism, clear goals, quantifiable models and measurements. The assertion is that unrealistic assumptions of economics have become taken for granted and tacitly included into theories and models of management. Guiding management to behave in a fashion that apparently makes these assumptions become “true”. Cases and illustrative examples are used to show how this influences the practice of decision makers and managers. (shrink)

A central aim within criminal justice ethics is to give a plausible justification concerning which type of acts ought to be criminalized by the state. One of the principles of criminalization which has been presented and critically discussed in the philosophical literature is the Offense Principle. The primary aim of this paper is to argue that unless a rather special and implausible objective list theory of well-being is accepted, the Offense Principle should be subsumed in the Harm Principle.

According to Priest, a proof can be distinct from itself in the same way that a number can. Priest does not specify any such number, so the present little note aims at filling this lacuna by providing a plain arithmetical code of a dialetheia similar to but simpler than the one presented in our recent work and thereby a natural number distinct from itself.

Objectives: Childhood cancer is a life-threatening disease that poses significant challenges to the life of the diagnosed child and his/her family members. Based on the ABCX-model, the aim of the current study was to explore the association between family functioning, cancer appraisal and the individual adjustment of patients, parents and siblings. Method: Participants were 60 children with leukemia or non-Hodgkin lymphoma, 172 parents and 78 siblings (115 families). Time since diagnosis varied from zero to 33 months. Patients, parents and siblings (...) completed the Family Environment Scale, Perceived Stress Scale, Situation-Specific Emotional Reactions Questionnaire and Pediatric Quality of Life Inventory/Maudsley Marital Questionnaire. Results: Family functioning and the appraisal of the cancer diagnosis proved to be related to patients’, parents’ and siblings’ cancer-related emotions and quality of life post-diagnosis. In addition, family members differed in their perception of some family functioning domains, the appraisal of the cancer diagnosis, positive feelings and quality of life. Discussion: Our findings led to the conclusion that family functioning and the appraisal of the cancer diagnosis are important for the individual adjustment of patients, parents and siblings when facing a diagnosis of cancer in the child. Differences across members within one family speak to the need of screening all family members and intervening at the level of the family unit. (shrink)

The enactive approach to cognition distinctively emphasizes autonomy, adaptivity, agency, meaning, experience, and interaction. Taken together, these principles can provide the new sciences of language with a comprehensive philosophical framework: languaging as adaptive social sense-making. This is a refinement and advancement on Maturana’s idea of languaging as a manner of living. Overcoming limitations in Maturana’s initial formulation of languaging is one of three motivations for this paper. Another is to give a response to skeptics who challenge enactivism to connect “lower-level” (...) sense-making with “higher-order” sophisticated moves like those commonly ascribed to language. Our primary goal is to contribute a positive story developed from the enactive account of social cognition, participatory sense-making. This concept is put into play in two different philosophical models, which respectively chronicle the logical and ontogenetic development of languaging as a particular form of social agency. Languaging emerges from the interplay of coordination and exploration inherent in the primordial tensions of participatory sense-making between individual and interactive norms; it is a practice that transcends the self-other boundary and enables agents to regulate self and other as well as interaction couplings. Linguistic sense-makers are those who negotiate interactive and internalized ways of meta-regulating the moment-to-moment activities of living and cognizing. Sense-makers in enlanguaged environments incorporate sensitivities, roles, and powers into their unique yet intelligible linguistic bodies. We dissolve the problematic dichotomies of high/low, online/offline, and linguistic/nonlinguistic cognition, and we provide new boundary criteria for specifying languaging as a prevalent kind of human social sense-making.

An argument against the use of non-medical egg freezing is that women should not use NMEF as it is an individualistic and morally problematic answer to the social problems that women face, for instance, in the labour market. Instead of allowing or expecting women to deal with these problems individually, we should address them by challenging the patriarchal structure of the labour market—for example, by securing equal pay and affordable childcare. In a recent article in Journal of Medical Ethics, I (...) argue that we should distinguish between different versions of this kind of reasoning and that all the versions discussed are implausible.1 In three separate comments following my article in the March 2021 issue of JME, Moen,2 Segers3 and Campo-Engelstein4 have supported and criticised some of my results.

Apart from a short clarification of what neuro-doping is, the aim of this article is twofold. First to give a few reasons in favour of having a special issue on neuro-doping. Second to present an overview of the articles in this issue. One reason for having this special issue, is that it needs to be established whether methods such as transcranial direct-current stimulation should be added to World Anti-Doping Agency’s prohibited list or not, as it is currently under discussion by (...) WADA. Another reason for dealing with the ethics of neuro-doping is that ethical analysis of the use or possible use of neuro-doping in sport is a neglected subject. This issue cover a wide range of ethical analyses of the use of neuro-doping among athletes, chess players, e-gamers and even couch potatoes. For example, whether tDCS ought to be prohibited by WADA and/or the state; or whether its use ought to be promoted by the state; whether the use of neuro-doping is unfair; or whether it should be allowed for businesses to advertise high-sugar, high-caffeine beverages to youngsters.

This article addresses the relationship between content, voice, and body language in persuasive communication and the contribution of these three elements of persuasive performances to its overall persuasiveness. Findings are presented from two separate laboratory experiments. In the first experiment three versions of a video displaying a speech were shown to three different groups of participants: without vocal emphasis and without gestures of the speaker, with vocal emphasis but without gestures, with vocal emphasis and gestures. Audio tracks of the first (...) two experimental conditions were later used in the second experiment to analyze the effects of vocal emphasis when no visual cues are present. Measurement included a questionnaire as well as Real Time Response-measurement. It was found that content dominates the effect of the speech; emphasis and gestures, however, improved the perception of some features of the speech, such as liveliness and power. Audio-only versions yielded similar results but were rated more favorably in general. (shrink)
