The Greeks attributed to Thales a great many discoveries and achievements. Few, if any, of these can be said to rest on thoroughly reliable testimony, most of them being the ascriptions of commentators and compilers who lived anything from 700 to 1,000 years after his death—a period of time equivalent to that between William the Conqueror and the present day. Inevitably there ilso accumulated round the name of Thales, as round that of Pythagoras , a number of anecdotes of varying (...) degrees of plausibility and of no historical worth whatsoever. These and the achievements credited to Thales have, of course, been painstakingly brought together by Hermann Diels in Der Fragmente der Vorsokratiker. Useful and necessary as this work undoubtedly is, it nevertheless has probably contributed as much as any other book to the exaggerated and false Aew of Thales which we meet in so many modern histories of science or philosophy, and which it is the purpose of this article to combat.

BackgroundThe emergence of artificial intelligence (AI) in medicine has prompted the development of numerous ethical guidelines, while the involvement of patients in the creation of these documents lags behind. As part of the European PROFID project we explore patient perspectives on the ethical implications of AI in care for patients at increased risk of sudden cardiac death (SCD).AimExplore perspectives of patients on the ethical use of AI, particularly in clinical decision-making regarding the implantation of an implantable cardioverter-defibrillator (ICD).MethodsSemi-structured, future scenario-based (...) interviews were conducted among patients who had either an ICD and/or a heart condition with increased risk of SCD in Germany (n = 9) and the Netherlands (n = 15). We used the principles of the European Commission’s Ethics Guidelines for Trustworthy AI to structure the interviews.ResultsSix themes arose from the interviews: the ability of AI to rectify human doctors’ limitations; the objectivity of data; whether AI can serve as second opinion; AI explainability and patient trust; the importance of the ‘human touch’; and the personalization of care. Overall, our results reveal a strong desire among patients for more personalized and patient-centered care in the context of ICD implantation. Participants in our study express significant concerns about the further loss of the ‘human touch’ in healthcare when AI is introduced in clinical settings. They believe that this aspect of care is currently inadequately recognized in clinical practice. Participants attribute to doctors the responsibility of evaluating AI recommendations for clinical relevance and aligning them with patients’ individual contexts and values, in consultation with the patient.ConclusionThe ‘human touch’ patients exclusively ascribe to human medical practitioners extends beyond sympathy and kindness, and has clinical relevance in medical decision-making. Because this cannot be replaced by AI, we suggest that normative research into the ‘right to a human doctor’ is needed. Furthermore, policies on patient-centered AI integration in clinical practice should encompass the ethics of everyday practice rather than only principle-based ethics. We suggest that an empirical ethics approach grounded in ethnographic research is exceptionally well-suited to pave the way forward. (shrink)

Developments in medical big data analytics may bring societal benefits but are also challenging privacy and other ethical values. At the same time, an overly restrictive data protection regime can form a serious threat to valuable observational studies. Discussions about whether data privacy or data solidarity should be the foundational value of research policies, have remained unresolved. We add to this debate with an empirically informed ethical analysis. First, experiences with the implementation of the General Data Protection Regulation (GDPR) within (...) a European research consortium demonstrate a gap between the aims of the regulation and its effects in practice. Namely, strictly formalised data protection requirements may cause routinisation among researchers instead of substantive ethical reflection, and may crowd out trust between actors in the health data research ecosystem; while harmonisation across Europe and data sharing between countries is hampered by different interpretations of the law, which partly stem from different views about ethical values. Then, building on these observations, we use theory to argue that the concept of trust provides an escape from the privacy-solidarity debate. Lastly, the paper details three aspects of trust that can help to create a responsible research environment and to mitigate the encountered challenges: trust as multi-agent concept; trust as a rational and democratic value; and trust as method for priority setting. Mutual cooperation in research—among researchers and with data subjects—is grounded in trust, which should be more explicitly recognised in the governance of health data research. (shrink)

In this article, we use the theory of Information Ethics to argue that deceased people have a prima facie moral right to privacy in the context of health data research, and that this should be reflected in regulation and guidelines. After death, people are no longer biological subjects but continue to exist as informational entities which can still be harmed/damaged. We find that while the instrumental value of recognising post-mortem privacy lies in the preservation of the social contract for health (...) research, its intrinsic value is grounded in respect for the dignity of the post-mortem informational entity. However, existing guidance on post-mortem data protection is available only in the context of genetic studies. In comparing the characteristics of genetic data and other health-related data, we identify two features of DNA often given as arguments for this genetic exceptionalism: relationality and embodiment. We use these concepts to show that at the appropriate Level of Abstraction, there is no morally relevant distinction between posthumous genetic and other health data. Thus, genetic data should not automatically receive special moral status after death. Instead we make a plea for ‘contextual exceptionalism’. Our analysis concludes by reflecting on a real-world case and providing suggestions for contextual factors that researchers and oversight bodies should take into account when designing and evaluating research projects with health data from deceased subjects.

BackgroundConsent for data research in acute and critical care is complex as patients become at least temporarily incapacitated or die. Existing guidelines and regulations in the European Union are of limited help and there is a lack of literature about the use of data from this vulnerable group. To aid the creation of a patient-centred framework for responsible data research in the acute setting, we explored views of patients and next-of-kin about the collection, storage, sharing and use of genetic and (...) health-related data for observational research.MethodsWe conducted qualitative interviews (n = 19) with Dutch sudden cardiac arrest survivors who donated clinical and socio-economic data and genetic samples to research. We also interviewed their next-of-kin. Topics were informed by ethics literature and we used scenario-sketches to aid discussion of complex issues.ResultsSudden cardiac arrest survivors displayed limited awareness of their involvement in health data research and of the content of their given consent. We found that preferences regarding disclosure of clinically actionable genetic findings could change over time. When data collection and use were limited to the medical realm, patients trusted researchers to handle data responsibly without concern for privacy or other risks. There was no consensus as to whether deferred consent should be explicitly asked from survivors. If consent is asked, this would ideally be done a few months after the event when cognitive capacities have been regained. Views were divided about the need to obtain proxy consent for research with deceased patients’ data. However, there was general support for the disclosure of potentially relevant post-mortem genetic findings to relatives.ConclusionsSudden cardiac arrest patients’ donation of data for research was grounded in trust in medicine overall, blurring the boundary between research and care. Our findings also highlight questions about the acceptability of a one-time consent and about responsibilities of patients, researchers and ethics committees. Finally, further normative investigation is needed regarding the (continued) use of participants’ data after death, which is of particular importance in this setting. Our findings are thought to be of relevance for other acute and life-threatening illnesses as well. (shrink)

In a recent paper I discussed the origin of the concept of the climata in Greek geography, and adduced reasons for attributing the formulation and elaboration of the concept to Hipparchus . The above passage in Strabo was naturally mentioned in the course of the argument, and I drew attention in a footnote to the unsatisfactory nature of the account given by him of the climata. I now propose to examine the passage in more detail.

The climata played an important role in Greek geography. As used in the mathematical geography of Hipparchus and Ptolemy the word denotes a narrow belt or strip of land, 400 stades wide, on each side of a parallel of latitude; inhabitants of the same clitma were assumed to be situated in the same geographical latitude, since, for practical purposes, the celestial phenomena, lengths of the longest and shortest days, and general climatic conditions did not change appreciably within this distance. We (...) may compare the modern conception of arbitrary zones each possessing its own standard time; but whereas these are belts of longitude contiguous to each other, the climata were belts of latitude not necessarily contiguous.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

Strengthening the abilities of smallholder farmers in developing countries, particularly women farmers, to produce for both home and the market is currently a development priority. In many contexts, ownership of assets is strongly gendered, reflecting existing gender norms and limiting women’s ability to invest in more profitable livelihood strategies such as market-oriented agriculture. Yet the intersection between women’s asset endowments and their ability to participate in and benefit from agricultural interventions receives minimal attention. This paper explores changes in gender relations (...) and women’s assets in four agricultural interventions that promoted high value agriculture with different degrees of market-orientation. Findings suggest that these dairy and horticulture projects can successfully involve women and increase production, income and the stock of household assets. In some cases, women were able to increase their control over production, income and assets; however in most cases men’s incomes increased more than women’s and the gender-asset gap did not decrease. Gender- and asset-based barriers to participation in projects as well as gender norms that limit women’s ability to accumulate and retain control over assets both contributed to the results. Comparing experiences across the four projects, especially where projects implemented adaptive measures to encourage gender-equitable outcomes, provides lessons for gender-responsive projects targeting existing and emerging value chains for high value products. Other targeted support to women farmers may also be needed to promote their acquisition of the physical assets required to expand production or enter other nodes of the value chain. (shrink)

An atom is confined to a box in its ground state. An attempt is made to observe it in the left half of the box by scattering photons out of a photon wave packet passing through this half of the box. If no photons are scattered, the atom is missing. It is located on the right side of the box and its wave function is changed. The expectation value of the combined atom and photon energy is increased. For the other (...) alternative, that the atom is found on the left side, the expectation value is decreased. By including both alternatives, it is shown that the mean energy is conserved. (shrink)

The juxtaposition of models of God and Christian faith may seem repugnant to many, as models are tentative and faith aims at an abiding certainty. In fact, for many Christians, using models of God in worship amounts to idolatry. By examining Biblical and extra-Biblical views of idolatry, I argue that models are not idols. To the contrary, the practice of God-modeling inoculates Christians against one of the most seductive idols of our age: the love of certainty. Furthermore, by examining meditations (...) upon certainty in Melville’s Moby Dick and the early discourses of the Buddha, I suggest that overweening conviction is a vice that hinders rather than guarantees Christian discipleship, and that Christian faith is better defined as any or all of the following: relative confidence in propositions, faithful relationship, and a virtue of disciplined credulity.

Herman Melville’s Moby Dick (1851) may have set the lengthy standard for books treating whales, but D. Graham Burnett has more than matched that standard with his hefty, almost eight-hundred page tome, The Sounding of the Whale. The requisite explanatory subtitle specifies the author’s intent to write the history of what he refers to as “whale science” spanning the twentieth century. The book divides rather naturally into three complementary sections. The opening two chapters discuss early conservation efforts aimed at (...) managing the whale industry. Next, two more chapters investigate the formation of the International Whaling Commission (IWC). A final chapter argues that dolphin research in the 1960s and 1970s led to the strident environmental concerns of the late twentieth century, including the drive to “save the whale” (the five chapters are bracketed by a lengthy introduction and conclusion).The most compelling features of Burnett’s book are delivered in the first four chapters.

There was once a leak from Hebdomadal Council. The Assessor told her husband, who told my wife, who told me that Monday afternoon had been spent discussing what Lucas would say if various courses of action were adopted, leading to the conclusion that it would be best to do nothing. I was flattered, but a bit surprised. The tide of philosophical scepticism had ebbed, and it was generally allowed that a reasonable way of discovering what someone would say was to (...) ask him. Dick Southwood did: he would quiz me in Common Room – sometimes ending "Thank you for letting me bounce these ideas off you" – and had reliable information about how one member of Congregation would react to various proposals. And not only me: he was a listening Vice-Chancellor, who used to bike from Wellington Square to Merton for lunch, greeting many as he passed them, and ready to stop if occasion warranted it. Of course, there are many other leaks. I remember once attending a meeting in the Town Hall to argue for cycle tracks, and someone coming up to me, and saying, "You’re having a tussle with Council, aren’t you? I think you ought to see the minutes of their latest meeting"; the next day there was a copy in my pigeon hole, giving me just the ammunition I needed. What members of Congregation tend the forget is the existence – the other side of the green baize door, so to speak – of a corps of bedells. (shrink)

The cosmological and teleological argument both start with some contingent feature of the actual world and argue that the best or only explanation of that feature is that it was produced by an intelligent and powerful supernatural being. The cosmological argument starts with a general feature, such as the existence of contingent being or the presence of motion and uses some version of the Principle of Sufficient Reason to conclude that this feature must have an explanation. The debate then focuses (...) on two points: first, whether the PSR in question is true, and second, whether the explanation must involve God or at least some God-like being. The teleological argument begins with a general feature of the cosmos judged to have value, such as the existence of intelligent life or the presence of order in the universe, and argues, usually inductively but sometimes deductively, that this feature is to be explained by the agency of a powerful supernatural being. Here, the debate tends to focus on whether there are alternate naturalistic explanations, such as Darwinian evolution. (shrink)

A plural referring expression (‘the Fs’ or ‘Tom, Dick and Harriet’) may be used to refer either distributively, saying something which applies to each of the Fs individually, or collectively, to the Fs taken as a single totality. Predicate Logic has to analyse both uses in terms of singular reference, treating them quite differently in so doing; but we think of such an expression as functioning in basically the same way in both kinds of use. This understanding can be (...) vindicated if we recognise that what a plural referring expression picks out is not either an aggregate simpliciter or a set, but a plurality– an aggregate taken relative to a principle for individuating its constituents; this admits of being seen either as many things or as one. In any given case, it is the nature of what is being said about the plurality which tells us whether the reference to it is to be taken as distributive, collective, or a combination of the two. Talk about pluralities is extensional. Augmenting Predicate Logic to accommodate the distinctive inference‐pattern associated with distributive plural reference is simple – and arguably necessary, to cope with cases in which distributive and collective reference are essentially combined (e.g., attributions of concerted action).
