Many authors have proposed constraining the behaviour of intelligent systems with ‘machine ethics’ to ensure positive social outcomes from the development of such systems. This paper critically analyses the prospects for machine ethics, identifying several inherent limitations. While machine ethics may increase the probability of ethical behaviour in some situations, it cannot guarantee it due to the nature of ethics, the computational limitations of computational agents and the complexity of the world. In addition, machine ethics, even if it were to (...) be ‘solved’ at a technical level, would be insufficient to ensure positive social outcomes from intelligent systems. (shrink)

This paper examines the UK’s response to a recent European Clinical Trials Directive, namely the Department of Health, Central Office for Research Ethics Committee guidance, Governance Arrangements for NHS Research Ethics Committees. The revisions have been long awaited by researchers and research ethics committee members alike. They substantially reform the ethical review system in the UK. We examine the new arrangements and argue that though they go a long way toward addressing the uncertainty surrounding ethics committee function, the system favours (...) the facilitation of research over the protection of the dignity and welfare of research participants.

This paper focuses on the fact that AI is predominantly portrayed as white—in colour, ethnicity, or both. We first illustrate the prevalent Whiteness of real and imagined intelligent machines in four categories: humanoid robots, chatbots and virtual assistants, stock images of AI, and portrayals of AI in film and television. We then offer three interpretations of the Whiteness of AI, drawing on critical race theory, particularly the idea of the White racial frame. First, we examine the extent to which this (...) Whiteness might simply reflect the predominantly White milieus from which these artefacts arise. Second, we argue that to imagine machines that are intelligent, professional, or powerful is to imagine White machines because the White racial frame ascribes these attributes predominantly to White people. Third, we argue that AI racialised as White allows for a full erasure of people of colour from the White utopian imaginary. Finally, we examine potential consequences of the racialisation of AI, arguing it could exacerbate bias and misdirect concern. (shrink)

Researchers have frequently complained that the NHS ethical review system stifles good research. At last measures are being put in place to address this criticism, but will they undermine the protection of research participants? The Declaration of Helsinki recognizes that medicine will not progress without good quality research, but also demands that the well-being of research participants takes precedence over the interests of science and society. This article examines the implications of the ongoing reform of the NHS research ethics review (...) system for researchers, ethics committees and research participants. (shrink)

There are entitlements, opportunities, and rights presently reserved to married couples by the basic structure of society, its major social institutions. Some claim that this is as it should be. But given the abiding effects of the basic structure on the prospects of individuals living within it, restrictions on liberty built into the basic structure require justification. One might think that we could justify reserving the benefits of marriage to married couples by appealing to harm prevention. In this paper, I (...) argue that the prospects of doing so successfully are dim. (shrink)

This paper exposes some examples of continuing murky thinking concerning holism. The exposure is a prelude to noting the importance of proximity in causal explanations of illnesses and wounds. The paper then draws attention to how the proximate should not hold exclusive sway regarding what constitutes best nursing treatment and care. The error of excessive preference for proximity is shown to be an error, using as an example the treatment of leg ulcers. One component of holism that can be clearly (...) expressed amounts therefore simply to the claim: resist the error of excessive proximity preference, resist the error of concentrating solely on nearness. It is left open whether there is any further sense to be gleaned from the holistic babble. (shrink)

Peter Cave gets to grips with maths, God and the meaning of life.

In 1962 I offered an analysis of the Line and Cave which maintained that the four main divisions of each are parallel and interpreted the three stages of ascent in the Cave allegory as representing the three stages in Plato's educational programme: music and gymnastic, mathematics and dialectic. At that time a major portion of my task was to counter arguments which purported to show that the Line and Cave could not be parallel. The present situation is (...) quite different since recent writers, for the most part, not only take the four main divisions of the Cave as parallel to those of the Line, but also accept the restriction of the Cave allegory to moral and mathematical education as a crucial step in the establishing of this fact. This last move, which is clearly in harmony with the form and content of the Republic, enables us to allow for the ordinary unenlightened man to be at the bottom level of the Cave without our having to suggest that he confuses the shadows of visual objects with their originals, which could well be the case if the Cave were taken to represent all sense perception as such. Despite fairly general agreement on these basic points of interpretation there remains, however, a wide divergence of opinion as to the significance of the various levels of education or moral awareness portrayed by the Cave. In keeping with several recent papers on this topic I shall focus my attention on the bottom two stages of this allegory: the state of the prisoners viewing shadows on the cave wall and that of the released prisoners, still in the cave, but turned around and looking at the puppets which cast these shadows.

Background Non-adherence to medication is associated with increased risk of relapse in patients with bipolar disorder. Objectives To validate patient-evaluated adherence to medication measured via smartphones against validated adherence questionnaire; and investigate characteristics for adherence to medication measured via smartphones. Methods Patients with BD evaluated adherence to medication daily for 6–9 months via smartphones. The Medication Adherence Rating Scale and the Rogers’ Empowerment questionnaires were filled out. The 17-item Hamilton Depression Rating Scale, the Young Mania Rating Scale and the Functional (...) Assessment Short Test were clinically rated. Data were collected multiple times per patient. The present study represents exploratory pooled reanalyses of data collected as part of two randomised controlled trials. Findings During the study 90.50% of the days were evaluated as ‘medication taken’, 6.91% as ‘medication taken with changes’ and 2.59% as ‘medication not taken’. Adherence to medication measured via smartphones was valid compared with the MARS. Younger age and longer illness duration were significant predictors for non-adherence to medication. Decreased affective symptoms measured with smartphone-based patient-reported mood and clinical ratings as well as decreased empowerment were associated with non-adherence. Conclusions Smartphone-based monitoring of adherence to medication was valid compared with validated adherence questionnaire. Younger age and longer illness duration were predictors for non-adherence. Increased empowerment was associated with adherence. Clinical implications Using smartphones for empowerment of adherence using patient-reported measures may be helpful in everyday clinical settings. Trial registration number NCT01446406 and NCT02221336. (shrink)

Certain paradoxes set us reeling endlessly. In surprise examination paradoxes, pupils' reasonings lead them to reel between expecting an examination and expecting none. With Newcomb's puzzle, choosers reel between reasoning in favour of choosing just one box and choosing two. The paradoxes demand an answer to what it is rational to believe or do. Highlighting other reelings and puzzles, this paper shows that the paradoxes should come as no surprise. The paradoxes demand an end to our reasoning when the conditions (...) they set ensure no end. They equivocate between, so to speak, reasoning in heaven and reasoning on earth; and, on the conditions set, not even an infinite god could reach a conclusion. (shrink)

In his short life, Alan Turing (1912-1954) made foundational contributions to philosophy, mathematics, biology, artificial intelligence, and computer science. He, as much as anyone, invented and showed how to program the digital electronic computer. From September, 1939, his work on computation was war-driven and brutally practical. He developed high speed computing devices needed to decipher German Enigma Machine messages to and from U-boats, countering the most serious threat by far to Britain..

We prove a Gleason-type theorem for the quantum probability rule using frame functions defined on positive-operator-valued measures, as opposed to the restricted class of orthogonal projection-valued measures used in the original theorem. The advantage of this method is that it works for two-dimensional quantum systems and even for vector spaces over rational fields—settings where the standard theorem fails. Furthermore, unlike the method necessary for proving the original result, the present one is rather elementary. In the case of a qubit, we (...) investigate similar results for frame functions defined upon various restricted classes of POVMs. For the so-called trine measurements, the standard quantum probability rule is again recovered.

While classical schools today typically exhibit a carefully considered approach to the linguistic arts of the trivium, the equally important mathematical arts of the quadrivium have received relatively little consideration. This being so, mathematics is often approached in ways that are not distinctly classical. This article seeks to establish the importance of the quadrivial arts as a means of ascending from lower to higher things. Though most know Plato’s comparison of a lack of education to being imprisoned in a (...) class='Hi'>cave, relatively few are familiar with the role the quadrivial arts play in ascending from the cave. Because the mathematical arts cultivate and direct the imagination, they enable students to move beyond sensible particulars to the formation of forms and figures by the mind. Thus, the mathematical arts help free us from an undue preoccupation with lower things and direct us toward the pursuit of knowledge and what truly is. (shrink)

Does which side of the fence we are on determine our perceptions of justice? Philosopher Eric M. Cave argues that rules of justice would benefit the members of a community little if individuals lacked an effective desire to comply with these rules. However, sometimes a sense of justice appears to do no more than to limit what individuals can do in pursuit of their own ends. Cave presents a provocative vehicle for self-examination.

In this witty and mischievous book, philosopher Peter Cave dissects the most controversial disputes today and uses philosophical argument to reveal that many issues are less straightforward than we'd like to believe. Leaving no sacred cow standing, Cave uses ingenious stories and examples to challenge our most strongly held assumptions. Is democracy inherently a good thing? What is the basis of so-called human rights? Is discrimination always bad? Are we morally obliged to accept refugees? In an age of (...) identity politics and so-called 'fake news', this book is an essential resource for reinvigorating genuine public debate - and an entertaining challenge to accepted wisdom.

A brief history of affective responses to AI.

Neoplatonic allegorical interpretation expounds how literary texts present philosophical ideas in an enigmatic and coded form, offering an alternative path to the divine truths. The Neoplatonist Porphyry’s _On the Cave of the Nymphs_ is one of the most significant allegorical interpretation handed down to us from Antiquity. This monograph, exclusively dedicated to the analysis of _On the Cave of Nymphs_, demonstrates that Porphyry interprets Homer’s verse from Odyssey 13.102-112 to convey his philosophical thoughts, particularly on the material world, (...) relationship between soul and body and the salvation of the soul through the doctrines of Plato and Plotinus. The Homeric cave of the nymphs with two gates is a station where the souls descend into genesis and ascend to the intelligible realm. Porphyry associates Odysseus’ long wanderings with the journey of the soul and its salvation from the irrational to rational through escape from all toils of the material world. (shrink)

In the Bayesian approach to quantum mechanics, probabilities—and thus quantum states—represent an agent’s degrees of belief, rather than corresponding to objective properties of physical systems. In this paper we investigate the concept of certainty in quantum mechanics. Particularly, we show how the probability-1 predictions derived from pure quantum states highlight a fundamental difference between our Bayesian approach, on the one hand, and Copenhagen and similar interpretations on the other. We first review the main arguments for the general claim that probabilities (...) always represent degrees of belief. We then argue that a quantum state prepared by some physical device always depends on an agent’s prior beliefs, implying that the probability-1 predictions derived from that state also depend on the agent’s prior beliefs. Quantum certainty is therefore always some agent’s certainty. Conversely, if facts about an experimental setup could imply agent-independent certainty for a measurement outcome, as in many Copenhagen-like interpretations, that outcome would effectively correspond to a preexisting system property. The idea that measurement outcomes occurring with certainty correspond to preexisting system properties is, however, in conflict with locality. We emphasize this by giving a version of an argument of Stairs [(1983). Quantum logic, realism, and value-definiteness. Philosophy of Science, 50, 578], which applies the Kochen–Specker theorem to an entangled bipartite system. (shrink)

Much has been written about recidivist punishments, particularly within the area of criminology. However there is a notorious lack of penal philosophical reflection on this issue. This book attempts to fill that gap by presenting the philosopher’s view on this matter as a way of furthering the debate on recidivist punishments.

In his study entitled “The Beginning and the Method of the Logic,” Dieter Henrich assumes an interpretive stance with regard to the beginning of Hegel’s Logic which is in staunch opposition to the scholarly tradition. That tradition, as Henrich tries to show, has almost unanimously rejected the dialectic of Becoming as untenable. This holds true not only for those critics whose ultimate aim was to discredit speculative dialectical method in general, but even for the members of Hegel’s own school, who (...) wished to salvage as much of the Logic as possible.

There is an international consensus that medical research involving humans should only be undertaken in accordance with ethical principles. Paradoxically though, there is no consensus over the kinds of activities that constitute research and should be subject to review. In the UK and elsewhere, research requiring review is distinguished from clinical audit. Unfortunately the two activities are not always easy to differentiate from one another. Moreover, as the volume of audit increases and becomes more formal in response to the demand (...) for evidence-based practice in medicine, the overlap between research and audit grows more acute. Arguably, similar ethical standards and systems for ensuring that those standards are met should be applied regardless of whether or not a project is classified as research or audit. At a time when the research ethics review system in the UK is undergoing significant reform it is important that the opportunity is not missed to address the longstanding research-audit problem. We discuss suggestions for further reform that addresses this issue. (shrink)

It has been a commonplace, embodied in philosophy curricula the world over, to think of Descartes' philosophy as he seems to present it: as a radical break with the past, as inaugurating a new philosophical problematic centred on epistemology and on a radical dualism of mind and body. In several ways, however, recent scholarship has undermined the simplicity of this picture. It has, for example, shown the considerable degree of literary artifice in Descartes' central works, and thereby brought out the (...) deceptive character of his self-presentation there. In particular, it has revealed the extent of his debts to the Neoplatonist tradition, particularly to Augustine, and of his engagement with the Scholastic commentators of his day. My aim in this paper is to push this interpretative tendency a step further, by bringing out Descartes' indebtedness to Plato. I begin by offering some reminders of the broadly Platonic nature of Cartesian dualism. I then argue that he provides clues sufficient for—and designed to encourage—reading the Meditations on First Philosophy in the light of distinctively Platonic doctrines, and in particular, as a rewriting of the Platonic allegory of the cave for modern times. It will further be argued that some puzzles about the Discourse on the Method can be resolved by recognizing that Descartes there presents himself as a Socratic enquirer after truth. I conclude by drawing attention to some practical benefits that flow from recognizing these linkages. (shrink)

I defend mereological nihilism, the view that there are no composite objects, against a challenge from ontological emergence, the view that some things have properties that are ‘something over and above’ the properties of their parts. As the nihilist does not believe in composite wholes, there is nothing in the nihilist's ontology to instantiate emergent properties – or so the challenge goes. However, I argue that some simples can collectively instantiate an emergent property, so the nihilist's ontology can in fact (...) accommodate emergent properties. Furthermore, I show that employing plural instantiation does not bloat the nihilist's ontology or ideology. (shrink)

Quantitative utilitarianism demands equal treatment of human and nonhuman animals where there are no relevant differences between them. A difference is relevant only if it excludes the animal from suffering evil if it is treated differently. Quantitative utilitarianism cannot, however, resolve conflicts of interest nor prove that painless killing of animals is morally wrong. For this we need a higher qualitativegood. I suggest Care, as Heidegger understands it, is such a good, and that it is the essence not only of (...) human, but of nonhuman animaI Dasein as well. Because animals care, we are morally obliged to desist from killing them, even painlessly. (shrink)

In the United Kingdom, the question of how much information is required to be given to patients about the benefits and risks of proposed treatment remains extant. Issues about whether healthcare resources can accommodate extended shared decision-making processes are yet to be resolved. COVID-19 has now stepped into this arena of uncertainty, adding more complexity. U.K. public health responses to the pandemic raise important questions about professional standards regarding how the obtaining and recording of consent might change or be maintained (...) in such emergency conditions, particularly in settings where equipment, medicines, and appropriately trained or specialized staff are in short supply. Such conditions have important implications for the professional capacity and knowledge available to discuss the risks and benefits of and alternatives to proposed treatment with patients. The government’s drive to expedite the recruitment to wards of medical students nearing the end of their studies, as well as inviting retired practitioners back into practice, raises questions about the ability of such healthcare providers to engage fully in shared decision-making.This article explores whether the legal duty on healthcare practitioners to disclose the material risks of a proposed medical treatment to a patient should be upheld during pandemic conditions or whether the pre-eminence of patient autonomy should be partly sacrificed in such exceptional circumstances. We argue that measures to protect public health and to respect autonomous decision-making are not mutually exclusive and that there are good reasons to maintain professional standards in obtaining consent to treatment even during acute pressures on public health systems.

This commentary is a response to ‘More than Skin Deep’ by Shelley M. Park, and a development of our own 2020 paper ‘The Whiteness of AI’. We aim to explain how representations of AI can be varied in one sense, whilst not being diverse. We argue that Whiteness’s claim to universal humanity permits a broad range of roles to White humans and White-presenting machines, whilst assigning a much narrower range of stereotypical roles to people of colour. Because the attributes of (...) AI in the popular imagination, such as intelligence, power and passing as human, are associated by the White racial frame with Whiteness, AI is cast predominantly as White. Following Sparrow, we suggest this presents a dilemma for those creating or representing AI. We discuss three possible solutions: avoiding anthropomorphisation, explicitly critiquing racial role-typing, and representing powerful AI as non-White. (shrink)

The pace of change and, indeed, the sheer number of clinical ethics committees has accelerated during the COVID-19 pandemic. Committees were formed to support healthcare professionals and to operationalise, interpret and compensate for gaps in national and professional guidance. But as the role of clinical ethics support becomes more prominent and visible, it becomes ever more important to address gaps in the support structure and misconceptions as to role and remit. The recent case of Great Ormond Street Hospital for Children (...) NHS Foundation Trust v MX, FX and X, [21]–[23] and [58]) has highlighted the importance of patient/family representation at clinical ethics committee meetings. The court viewed these meetings as making decisions about such treatment. We argue that this misunderstands the role of ethics support, with treatment decisions remaining with the clinical team and those providing their consent. The considered review by clinical ethics committees of the moral issues surrounding complex treatment decisions is not a matter of determining a single ethical course of action. In this article, we consider current legal understandings of clinical ethics committees, explore current concepts of ethics support and suggest how they may evolve, considering the various mechanisms of the inclusion of patients and their representatives in ethics meetings which is not standard in the UK.

The three puzzles here considered are shown to have a common structure. And in each, an agent is thrust into a cleverly contrived deliberatively unstable situation. The paper advocates a resolutely Pyrrhonian abandonment of the futile reasoning in which the agent is trapped and advocates an alternative strategy for escape.
