Philosophy, the ?love of wisdom”, is the product of our endless fascination and curiosity about the world ? the child of wonder.

How do you know that you exist? What does it mean to have a future? Are you the same thing as your brain? What does it mean to be free? How can you know what knowledge is? A woman was advising her anguished friend, 'Be philosophical - then you won't need to think about it.' Well, being philosophical is sometimes taken to mean that you should adopt a resigned attitude to the world - a quiet-ism - but the study that (...) is western philosophy, starting with the ancient Greeks and continuing today in universities, bars and cafes - even bedrooms - is far from quiet. Philosophers think - but not just that, for they think about thinking and they think about how we think about the world, about how we conceive of ourselves, about how we possess a sense of right and wrong, about how we find meaning in life (if we do). How to Think Like a Bat might not help you to think like a bat, but it will certainly help you to think like a philosopher. Smart, witty and engaging, this is a superb introduction to the subject by one of Britain's most engaging philosophical writers. (shrink)

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.

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.

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..

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)

The shift to a market economy in post-communist Eastern Europe has had a profound impact on science and scientists across the region, leading to reforms in research management practices and to drastic cuts in funding levels everywhere. Many countries are moving to a system of competitive research grants awarded on the basis of peer review. The introduction of peer review is not simply a technical matter. It signifies a fundamental change in the social structure of science, enhancing profession-al autonomy and (...) giving working scientists a voice in the allocation of resources. This book combines first-hand accounts of the reform process with analyses of the strengths and weaknesses of both peer review and quantitative indicators. (shrink)

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)

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)

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)

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.

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)

In Lives of the Sophists Philostratus depicts the widespread influence of Sophistic in the second and third centuries CE. Lives of Philosophers and Sophists by Eunapius is our only source concerning Neo-Platonism in the latter part of the fourth century CE. Of the distinguished Lemnian family of Philostrati, Flavius Philostratus "the Athenian, " ca. 170-205 CE, was a Greek sophist who studied at Athens and later lived in Rome. He was author of the admirable Life of Apollonius of Tyana and (...) of Lives of the Sophists, a treasury of information about notable sophists. Philostratus's sketches of sophists in action yield a fascinating picture of the predominant influence of Sophistic in the educational, social, and political life of the Empire in the second and third centuries. The Greek sophist and historian Eunapius was born at Sardis in 347 CE, but went to Athens to study and lived much of his life there teaching rhetoric and possibly medicine. He was initiated into the mysteries and was hostile to Christians. His Lives of Philosophers and Sophists is our only source for knowledge of Neo-Platonism in the latter part of the fourth century.

Professional control in the selection of treatment options for patients is changing. In light of social and legal developments emphasising patient choice and autonomy, and restricting medical paternalism and judicial deference, this article examines how far patients and families can demand NHS treatment in England and Wales. It considers situations where the patient is an adult with capacity, an adult lacking capacity and a child. In all three cases, there is judicial support for professional autonomy, but there are also inconsistencies (...) that have potential to elevate the importance of patient and family preferences. In combination, they may be perceived by healthcare professionals as an obligation to follow patient preferences, even where doing so conflicts with other professional obligations. It is argued that a more nuanced approach to shared decision-making could help clarify the boundaries of decision-making responsibility. (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.

Uncertainty around the role ‘super-spreaders’ play in the transmission and escalation of infectious disease is compounded by its broad and vague definition. It is a term that has been much used in relation to COVID-19, particularly in social media. On its widest definition, it refers to a propensity to infect a larger than average number of people. Given the biological, behavioural and environmental variables relevant to infectivity, this might be pertinent to almost any infected individual who is not physically isolated (...) from others. Nor is the term confined to individuals with a propensity to spread infectious disease: it can potentially be used to describe events, policies or settings. This article explores the use of the term and considers circumstances in which the wide definition can be problematic. One problem is that it can lead to undeserved apportionment of moral blame to alleged super-spreaders. Another is that it can detract from scientific investigation of the heterogeneity of COVID-19 transmission. The author calls for a clearer epidemiological definition. (shrink)

When consent to medical treatment is described as ‘valid’, it might simply mean that it has a sound basis, or it could mean that it is legally valid. Where the two meanings are regularly interchanged, however, it can lead to aspects of the sound basis or the legal requirements being neglected. This article looks at how the term is used in a range of guidance on consent to treatment and argues for consistency.

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.

Consider manipulation in which one agent, avoiding force, threat, or fraud mobilizes some non-concern motive of another so as to induce this other to behave or move differently than she would otherwise have behaved or moved, given her circumstances and her initial ranking of concerns. As an instance, imagine that I get us to miss the opening of a play that I have grudgingly agreed to attend by engaging your sublimated compulsive tendency to check the stove when we are halfway (...) to the theatre. Such motive manipulation is, I take it, widely regarded as morally worrisome. If it really is morally worrisome, then we should be able to explain adequately why it is so. But existing condemnations of manipulation come up short in this regard. In this paper, I develop and defend a more plausible account of the moral status of this phenomenon. (shrink)

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

Thinking with Literature offers a succinct introduction to a cognitive literary criticsm, broad in scope but focusing on a particular cluster of approaches, some of which have so far been little used. Explanatory chapters and sections alternate with close readings of literary texts from a wide range of different periods and genres. The literary readings are not mere 'examples' of cognitive topics, still less of hypotheses in cognitive science: the central argument is that cognitive criticism must draw its primary energies (...) from the complexities of literature itself. The main objective of the book is to induce a change of perspective in the reader: to see the point, and the extreme interest, of adopting a cognitive approach to literary criticism. (shrink)

A brief history of affective responses to AI.

This paper discusses the use of the Milgram obedience experiments and the Tuskegee syphilis study in the bioethical literature. The two studies are presented and a variety of uses of them identified and discussed. It is argued that the use of these studies as paradigms of problematic research relies on a reduction of their complexity. What is discussed is thus often constructions of these studies that are closer to hypothetical examples than to the real studies.

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)

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.

Recently, the US has joined many European jurisdictions in extending civil marriage to same sex as well as different sex dyads. Many liberals regard this as a development worth entrenching. But a prominent recent liberal challenge to civil marriage claims otherwise. According to this challenge, by defining and conferring civil marriage, the state privileges some relationships over others that serve equally well the important liberal goal of fostering effective liberal citizenship, in violation of a prominent interpretation of the doctrine of (...) state neutrality. Theorists who press this challenge, such as Elizabeth Brake and Tamara Metz, argue that it can be met effectively only by dismantling civil marriage and replacing it with more inclusive state-maintained arrangements. So far, prominent responses to this neutralist challenge to civil marriage have focused on the special value of either the relationships to which civil marriage currently extends, or the special value of civil marriage itself. In this article, I develop an alternative reply to this neutralist challenge to civil marriage, one focusing instead on the special vulnerabilities of some of the liberally valuable relationships to which civil marriage currently extends, amorous caregiving dyads.

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 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.

Let the marriage bond be the set of extralegal obligations to one another that individuals acquire in getting married. And let a conception of the marriage bond be an account of the nature and content of these. Here, I argue that the conception of this bond dominant among us is uncongenial to romantic love among individuals of a certain psychological type. Then, after articulating a conception more congenial to romantic love among such individuals, I argue that if we wish to (...) make marriage safer for love, we should make room in our thinking and practice for this conception, embracing a form of marital pluralism.

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.

Zenon d'Elee est connu par les paradoxes que nous a transmis Aristote, Achille et la Tortue etant le plus celebre. Dans l'histoire de la philosophie, les questions ainsi posees n'ont pas cesse de stimuler la reflexion des plus grands penseurs, et de susciter des reponses tres divergentes, dont l'erudition et l'epistemologie modernes se sont saisies a leur tour. Mais en France il n'existait pas d'ouvrage faisant le point de ces controverses. Celui-ci procede a un examen systematique de tous les textes (...) pertinents legues par l'Antiquite sur la pensee de Zenon, essentiellement ceux de Simplicius, Aristote et Platon. Le lecteur trouvera pour chacun d'eux, apres une traduction nouvelle, un commentaire suivi, tant sur le plan de la critique textuelle que du point de vue scientifique. Il disposera aussi d'une discussion methodique des interpretations proposees par les modernes. La signification des arguments de l'Eleate dans leur contexte intellectuel et leur unite d'inspiration sont ainsi mis en lumiere. La dialectique zenonienne est replacee dans les debats philosophiques de son temps et sa portee historique explicitee. Pointant les contradictions des conceptions regnantes, elle marque une etape preliminaire dans l'histoire du concept du continu, dont Aristote donna la premiere theorie coherente. (shrink)

Successful jokes involve incongruities, but not any incongruity will do—not, for example, one as blatantly bare as an explicit instance of the form p.~p. Substitution in such is no secure generator of fun; and stand-up comedians would be lucky to escape with their lives, if—at the Glasgow Empire on a Saturday night—they delivered one-liners such as “She came from Dungeness and not from Dungeness.” Build-up context, alcohol level, and delivery skills—and it is not impossible that any line, even the p.~p (...) instance, could secure some laughs; but laughs alone need indicate no joke. At a level virtually platitudinous, jokes require an incongruity—a tension—between expectations typically aroused by initial words and resultant sabotaging revelations. We could, no doubt, be a species that laughed at every expressed contradiction, yet one for which banana skins, sexual spasms, and implied inconsistencies raised no flicker. Which particular sayings generate incongruities and not mere laughter is no empirical matter, but one of logic, logic taken sufficiently widely to include semantics and pragmatics. These incongruities, with the masking, the movement and unmasking—the teasing, stripping, and exposed sabotage—are to be found within many philosophical paradoxes as well as within jokes. Laying bare the jokes’ mechanisms can help to resolve such paradoxes. Joking matter itself need be no joking matter; and as jokes and paradoxes rely upon veiled incongruities, an all-seeing god would see no joke and meet no paradox. (shrink)
