In the 70 years since Alan Turing’s ‘Computing Machinery and Intelligence’ appeared in Mind, there have been two widely-accepted interpretations of the Turing test: the canonical behaviourist interpretation and the rival inductive or epistemic interpretation. These readings are based on Turing’s Mind paper; few seem aware that Turing described two other versions of the imitation game. I have argued that both readings are inconsistent with Turing’s 1948 and 1952 statements about intelligence, and fail to explain the design of his game. (...) I argue instead for a response-dependence interpretation. This interpretation has implications for Turing’s view of free will: I argue that Turing’s writings suggest a new form of free will compatibilism, which I call response-dependence compatibilism. The philosophical implications of rethinking Turing’s test go yet further. It is assumed by numerous theorists that Turing anticipated the computational theory of mind. On the contrary, I argue, his remarks on intelligence and free will lead to a new objection to computationalism. (shrink)

Recent work in social robotics, which is aimed both at creating an artificial intelligence and providing a test-bed for psychological theories of human social development, involves building robots that can learn from ‘face-to-face’ interaction with human beings — as human infants do. The building-blocks of this interaction include the robot’s ‘expressive’ behaviours, for example, facial-expression and head-and-neck gesture. There is here an ideal opportunity to apply Wittgensteinian conceptual analysis to current theoretical and empirical work in the sciences. Wittgenstein’s philosophical psychology (...) is sympathetic to embodied and situated Artificial Intelligence (see Proudfoot, 2002, 2004b), and his discussion of facial-expression is remarkably modern. In this chapter, I explore his approach to facial-expression, using smiling as a representative example, and apply it to the canonical interactive face robot, Cynthia Breazeal’s Kismet (see e.g. Breazeal, 2009, 2002). I assess the claim that Kismet has expressive behaviours, with the aim of generating philosophical insights for AI. (shrink)

According to a rights forfeiture theory of punishment, liability to punishment hinges upon the notion that criminals forfeit their rights against hard treatment. In this paper, I assume the success of rights forfeiture theory in establishing the permissibility of punishment but aim to develop the view by considering how forfeited rights might be reclaimed. Built into the very notion of proportionate punishment is the idea that forfeited rights can be recovered. The interesting question is whether punishment is the sole means (...) for reclaiming forfeited rights. I argue for a pluralistic theory of rights reclamation, according to which, there are multiple ways by which a wrongdoer can recapture her forfeited rights. In particular, I argue that offering remorseful compensation is a valid means by which a wrongdoer might partially, or fully, reclaim her right against punishment. (shrink)

Trans and gender-nonconforming people sometimes say that certain gender norms are authentic for them. For example, a trans man might say that abiding by norms of masculinity tracks who he really is. Authenticity is sometimes taken to appeal to an essential, pre-social “inner self.” It is also sometimes understood as a moral notion. Authenticity claims about gender norms therefore appear inimical to two key commitments in feminist philosophy: that all gender norms are socially constructed, and that many domains of gender (...) norms are both morally and prudentially bad. I argue that that this apparent tension is illusory. Concordant with existing trans narratives of authenticity, I articulate an existentialist view that understands authenticity as a socially embedded, constructive project undertaken in a non-ideal social world, rather than a reflective uncovering of a pre-given, essential self. I then show that authenticity and morality can come apart; what is authentic for someone need not be either morally good or good for them. I conclude that the authenticity of gender norms does not cut against the feminist commitments that I identify. This conclusion enables a theoretical space that is both respectful of trans experience and critical of dominant gender norms, an important liberatory goal. (shrink)

In this article we focus on three key precepts shared by Confucianism and the African ethic of Ubuntu: the central value of community, the desirability of ethical partiality, and the idea that we tend to become morally better as we grow older. For each of these broad similarities, there are key differences underlying them, and we discuss those as well as speculate about the reasons for them. Our aim is not to take sides, but we do suggest ways that Ubuntu (...) and Confucianism might have something to learn from each other and perhaps come closer. We hope that our preliminary reflections can inspire further debate and thinking on a theme – dialogues between long-standing and large-scale non-Western traditions – that is bound to increase in importance as non-Western societies play a greater role in the global system and as the search continues for a 'global ethic'.

Turing used the expression “emotional” in three distinct ways: to state his philosophical theory of the concept of intelligence, to classify arguments for and against the possibility of machine intelligence, and to describe the education of a “child machine”. The remarks on emotion include several of the most important philosophical claims. This paper analyses these remarks and their significance for current research in Artificial Intelligence.

Early discussions of ?climate justice? have been dominated by economists rather than political philosophers. More recently, analytical liberal political philosophers have joined the debate. However, the philosophical discussion of climate justice remains in its early stages. This paper considers one promising approach based on human rights, which has been advocated recently by several theorists, including Simon Caney, Henry Shue and Tim Hayward. A basic argument supporting the claim that anthropogenic climate change violates human rights is presented. Four objections to this (...) argument are examined: the ?future persons? objection; the ?risk? objection; the ?collective causation? objection; and the ?demandingness? objection. This critical examination leads to a more detailed specification and defence of the claim that anthropogenic climate change violates human rights. (shrink)

The United States carceral system, as currently designed and implemented, is widely considered to be an immoral and inhumane system of criminal punishment. There are a number of pressing issues related to this topic, but in this essay, I will focus upon the problem of prison violence. Inadequate supervision has resulted in unsafe prison conditions where inmates are regularly threatened with rape, assault, and other forms of physical violence. Such callous disregard and exposure to unreasonable risk constitutes a severe violation (...) of the rights of prisoners by the state. While there have been numerous legal, political, and activist efforts to draw attention to this issue—with the goal of reforming and making prisons safer—my goal is different. I argue that inmates who are victims of prison violence should have their sentences automatically reduced. Two distinct arguments are advanced in support of this claim. First, I argue that acts of prison violence are a sort of state-mediated harm which can thus be appropriately described as punishment-constituting. Second, and more straightforwardly, I argue that the compensation owed to prisoners who are victims of prison violence may naturally take the form of a reduced sentence. (shrink)

Oppressive ideology regularly misrepresents features of structural injustice as normal or appropriate. Resisting such injustice therefore requires critical examination of the evaluative judgments encoded in shared concepts. In this paper, I diagnose a mechanism of ideological misevaluation, which I call "hermeneutical misfit." Hermeneutical misfit occurs when thick concepts, or concepts which both describe and evaluate, mobilize ideologically warped evaluative judgments which do not fit the facts (e.g. "slutty"). These ill-fitted thick concepts in turn are regularly deployed as if they merely (...) describe--a phenomenon I call "descriptive masquerade." I argue that, via descriptive masquerade, ill-fitted thick concepts smuggle in warped evaluative judgments alongside apparently value-neutral ‘mere facts’, a process which both reinforces those judgments and increases the difficulty of critique. I investigate the concept "obesity" as an example: scientists and medical practitioners will deploy this concept as if it "merely" describes, enabling the smuggling of a host of warped evaluative judgments. I suggest that, to resist this process, we should develop collective consciousness and articulate "meta-hermeneutical resources," or thick concepts which encode critique of other, ill-fitted concepts (e.g. "slut-shaming" or "fat-shaming").

Biomedical diagnostic science is a great deal less successful than we've been willing to acknowledge in bioethics, and this fact has far-reaching ethical implications. In this article I consider the surprising prevalence of medically unexplained symptoms, and the term's ambiguous meaning. Then I frame central questions that remain answered in this context with respect to informed consent, autonomy, and truth-telling. Finally, I show that while considerable attention in this area is given to making sure not to provide biological care to (...) patients without a need, comparatively little is given to the competing, ethically central task of making sure never to obstruct access to biological care for those with diagnostically confusing biological conditions. I suggest this problem arises from confusion about the philosophical value of vagueness when it comes to the line between biological and psychosocial needs. (shrink)

Gender norms can guide our sense of what we feel like we ought to do, even when we don't want them to. Understanding this norm responsiveness is an important part of understanding how oppressive gender systems are sustained. According to a social constructionist position, gender norm responsiveness happens as a result of social training, or socialization. It's often assumed that this training depends on our gender categories—that, for example, those who occupy the category “man” will be responsive to masculine norms, (...) and so on. Call this a category-based view. But trans and gender-nonconforming people are often responsive to gender norms that don't match our gender categories. This is sometimes taken as evidence for the conclusion that normative masculinity and femininity are somehow innate or pre-socialized. I reject this inference. I argue that we should instead dispense with a category-based view, and instead adopt a traits-based view. Gender norms apply to individuals on the basis of the gender-coded traits that they express. A traits-based view represents a social constructionist account of gender norms which leaves room for trans and GNC experiences of normative gender, and thus represents an important step towards creating inclusive theory.

The struggle by black people to obtain freedom, justice, and dignity is as old as this nation. At times, great and inspiring leaders rose out of desperate situations to give confidence and feelings of empowerment to the black community. Most of these leaders urged their people to strive for racial equality. They were firmly wedded to the idea that the courts and judiciary were the vehicle to better the social position of blacks. In spite of dramatic civil rights movements and (...) periodic victories in the legislatures, black Americans by no means are equal to whites. Racial equality is, in fact, not a realistic goal. By constantly aiming for a status that is unobtainable in a perilously racist America, black Americans face frustration and despair. Over time, our persistent quest for integration has hardened into self-defeating rigidity. (shrink)

We generally accept that medicine’s conceptual and ethical foundations are grounded in recognition of personhood. With patients in vegetative state, however, we’ve understood that the ethical implications of phenomenal consciousness are distinct from those of personhood. This suggests a need to reconsider medicine’s foundations. What is the role for recognition of consciousness (rather than personhood) in grounding the moral value of medicine and the specific demands of clinical ethics? I suggest that, according to holism, the moral value of medicine is (...) secured when conscious states are recognized in everyday medical science. Moreover, consciousness fully motivates traditional principles of clinical ethics if we understand respect for autonomy as respect for the dominion of an experiencer in the private, inescapable realm of bodily experience. When medicine’s foundations are grounded in recognition of consciousness, we understand how patients fully command respect even when they lack capacity to exercise their bodily dominion through decision-making.

What position on dualism does medicine require? Our understanding of that ques- tion has been dictated by holism, as defined by the biopsychosocial model, since the late twentieth century. Unfortunately, holism was characterized at the start with con- fused definitions of ‘dualism’ and ‘reductionism’, and that problem has led to a deep, unrecognized conceptual split in the medical professions. Some insist that holism is a nonreductionist approach that aligns with some form of dualism, while others insist it’s a reductionist view (...) that sets out to eradicate dualism. It’s important to consider each version. Nonreductive holism is philosophically consistent and clinically unprob- lematic. Reductive holism, however, is conceptually incoherent—yet it is the basis for the common idea that the boundary between medical and mental health disorders must be vague. When we trace that idea through to its implementation in medical practice, we find evidence that it compromises the safety of patient care in the large portion of cases where clinicians grapple with diagnosis at the boundary between psychiatry and medicine. Having established that medicine must embrace some form of nonreduc- tionism, I argue that Chalmers’ naturalistic dualism is a stronger prima facie candidate than the nonreductive alternatives. Regardless of which form of nonreductionism we prefer, some philosophical corrections are needed to give medicine a safe and coherent foundation. (shrink)

This study emphasizes the importance of enhancing food safety and hygiene practices among sidewalk vendors to safeguard public health in Balayan Public Market. Employing a mixed-methods approach, with both quantitative and qualitative components, a diverse sample of 55 consumers, 5 sidewalk vendors, and 5 market administrators was selected using a combination of purposive and random sampling techniques under non-probability sampling. Microbial investigations were conducted during both the initial sampling and testing phase (A) and subsequent sampling and testing phase (B) on (...) popular street food items at Lipa Quality Control Inc., including chicken nuggets, chicken nugget sauce (sweet and vinegar), Isaw, Isaw sauce, Proben, Proben sauce, Calamares, Calamares Vinegar Sauce, Kwek- Kwek, and Kwek-Kwek sauce. The findings reveal that “Isaw and Chicken Nuggets Sauce (Sweet)” had a result of “Too Numerous To Count (TNTC),” indicating an extraordinarily high bacteria count. This underscores the imperative need to raise awareness and provide targeted guidance to sidewalk vendors regarding essential food handling, storage, and sanitation practices. Therefore, a sanitary action plan is developed to promote community engagement, educational initiatives, and regulatory support, enhancing food safety practices among sidewalk vendors and ensuring a safer and healthier food environment.

Recently, the concept of "gender identity" has enjoyed a great deal of attention in gender metaphysics. This seems to be motivated by the goal of creating trans-inclusive theory, by explaining trans people's genders. In this paper, we aim to unmotivate this project. Notions of "gender identity" serve important pragmatic purposes for trans people, such as satisfying the curiosity of non-trans people, and, relatedly, securing our access to important goods like legal rights and medical care. However, we argue that this does (...) not mean that "gender identity" is a metaphysically substantial thing that deserves extensive theoretical attention. There are reasons to be skeptical of such a concept. We trace the history of "gender identity," primarily to identify its roots in trans-antagonistic medical theory and its connections to the problematic "wrong-body" model--a legacy that has pathologized and flattened trans experience. Moreover, we argue that trans people primarily use "gender identity" to explain ourselves to non-trans people, rather than to discuss ourselves among ourselves. Thus, we urge theorists to resist the urge to substantiate gender identity. Instead, we encourage the development of new and better concepts, ones that attend to the lived realities of trans community and the flourishing gender terms and practices that are constructed there. If these lived realities are taken seriously, there is no need to “explain” trans people’s genders; we can simply see them as they are. (shrink)

Philosophers who defend a person’s right, under certain circumstances, to end his own life or to have a physician end it for him typically appeal both to respect for patient autonomy and to considerations of beneficence. Neither autonomy alone nor beneficence alone can ground a persuasive case for euthanasia. I argue, however, that the standard argument for euthanasia is unsound. It is not possible to combine the principles of autonomy and beneficence in such a way as to justify euthanasia for (...) those who request it and are either incurably ill, in irremediable pain, or fearful of future incapacity, while excluding both involuntary euthanasia and assisted death for those who request it despite being neither incurably ill, in irremediable pain nor fearful of future incapacity.

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research.

Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

The dominance of the Abrahamic tradition in contemporary analytic philosophy of religion has led some to call for greater exploration of alternatives to the traditional conception of God, such as Pantheism, Ultimism, and Axiarchism. While we think this call for alternatives is important, we go in a different direction. Rather than explore and defend alternative conceptions of God, we defend a range of fairly traditional but non-religious conceptions of God. This range of views, from deism to philosophical theism, enjoys a (...) variety of benefits over its religious competitors and deserves greater attention. (shrink)

The first and greatest commandment according to Jesus, and so the one most central to Christian practice, is the command to love God. We argue that this commandment is best interpreted in aretaic rather than deontic terms. In brief, we argue that there is no obligation to love God. While bad, failure to seek and enjoy a union of love with God is not in violation of any general moral requirement. The core argument is straightforward: relations of intimacy should not (...) be morally imposed upon autonomous beings. We contend that such reasoning applies to human beings’ relationship to God. So, even if our ultimate end is to enjoy communion with God, God has no right that human beings seek a relationship with him. If this is correct, then the command to ‘love God’ is not the sort of moral principle that can be supported by threats of hellfire or other forms of coercion. (shrink)

The ability to solve problems is a prerequisite in preparing mathematics preservice teachers. This study assessed preservice teachers’ problem-solving difficulties and performance, particularly in worded problems on number sense, measurement, geometry, algebra, and probability. Also, academic profile differences in the preservice teacher’s problem-solving performance and common errors were determined. A descriptive-comparative research design was employed with 158 random respondents. Data were gathered face-to-face during the first semester of the school year 2022-2023, and data were analyzed with the aid of jamovi (...) software, ensuring ethical measures. Overall findings revealed that the preservice teachers experienced average difficulty in solving problems. The low performance of the preservice teachers on the given problems was also demonstrated. Further analysis revealed a significant difference between the preservice teachers’ problem-solving performance based on their subject preference and program. Moreover, the error analysis revealed that the preservice teachers incurred comprehension errors in misrepresentation, misinterpretation, and miscalculation. These results will serve as a measure for policymakers and curriculum developers of the teacher education institution concerned to make relevant enhancements to the math courses offered in the elementary and secondary education programs.

We respond to a Letter to the Editor regarding "Principlism and contemporary ethical considerations for providers of transgender health care." We address criticisms by Castle & Klein (2024) of blatant fatphobia related to the ethical elements concerning BMI restrictions for gender-affirming surgery. Our response corrects several mischaracterizations of the article and clarifies our position. My co-authors and I remain focused on advocating for patient-centered, ethically sound, evidence-based, and equitable healthcare policies.

Background: Transgender health care is a subject of much debate among clinicians, political commentators, and policy-makers. While the World Professional Association of Transgender Health (WPATH) Standards of Care (SOC) establish clinical standards, these standards contain implied ethics but lack explicit focused discussion of ethical considerations in providing care. An ethics chapter in the SOC would enhance clinical guidelines. Aims: We aim to provide a valuable guide for healthcare professionals, and anyone interested in the ethical aspects of clinical support for gender (...) diverse and transgender people of all ages. Recognizing that the WPATH is a global association, we address broad challenges. We offer a reflection on general ethical principles, providing conceptual tools for healthcare providers, patients, and families to navigate the specific challenges they might encounter in transgender health care, in line with WPATH’s worldwide mission and scope. Method: This article employs a descriptive analysis, and our framework of reference is the four principles of biomedical ethics: respect for autonomy, beneficence, nonmaleficence, and justice. Results: The article presents a discussion on the four ethical principles as applied to transgender health care. We address issues such as respect for patient autonomy in decision-making, the role of beneficence and nonmaleficence in clinical interventions, and the importance of justice in equitable treatment and access to care. Some of the ethical concerns we address in this article pertain to the current sociopolitical climate, where there has been increasing legal interference, internationally, for transgender and nonbinary people, particularly youth, seeking medical care. Discussion: We highlight the interplay between ethical principles and clinical practice, underscoring the need for ethical guidance in addressing the diverse challenges faced by healthcare providers and patients in transgender health care. We advocate for continuous refinement of ethical thinking to ensure that transgender health care is not only medically effective but also ethically sound. (shrink)

How can we improve business ethics education for the twenty first century? This study evaluates the effectiveness of a visual case exercise in the form of a 3D immersive game given to undergraduate students at two UK Universities as part of a mandatory business ethics module. We propose that due to evolving learning styles, the immersive nature of interactive games lends itself as a vehicle to make the learning of ethics more ‘concrete’ and ‘personal’ and therefore more engaging. To achieve (...) this, we designed and built an immersive 3D simulation game in the style of a visual case. The effectiveness of the game was evaluated using a mixed methods approach measuring recognised and adapted constructs from the technology acceptance model. Results demonstrate that students found the game beneficial to their learning of ethics with the development of knowledge and skills applicable to the real world and that they engaged with the process due to game elements. Findings demonstrate the potential for the development of simulated games to teach ethics at all levels and modes of delivery and the contribution of this type of visual case model as a pedagogic method.

Kampus Merdeka was part of the Merdeka Belajar policy released by the Indonesian Ministry of Education, Culture, Research, and Technology (Kemendikbudristek) at the end of January 2020. This study focuses on a university program that gave students opportunities to develop skills in accordance with their talents and interests by entering the workforce right away as training for future careers. Until the middle of September 2022, 12 programs had launched. To provide a reliable reference, a comprehensive analysis of the Merdeka Curriculum (...) program was carried out in this work. We took a qualitative approach, conducting observations and interviews with fellow actors as well as a thorough analysis of pertinent databases on the related subjects. We found that active student participation and support from the university are the keys to the success of Kampus Merdeka. Furthermore, serious commitment is needed from all parties to gain a company’s trust. This study is important to gain deep insights into the Kampus Merdeka policy so that the needs of Kurikulum Merdeka can be met effectively. (shrink)

Despite the recent proliferation of scientific, clinical, and narrative accounts of auditory verbal hallucinations, the phenomenology of voice hearing remains opaque and undertheorized. In this article, we outline an interdisciplinary approach to understanding hallucinatory experiences which seeks to demonstrate the value of the humanities and social sciences to advancing knowledge in clinical research and practice. We argue that an interdisciplinary approach to the phenomenology of AVH utilizes rigorous and context-appropriate methodologies to analyze a wider range of first-person accounts of AVH (...) at 3 contextual levels: cultural, social, and historical; experiential; and biographical. We go on to show that there are significant potential benefits for voice hearers, clinicians, and researchers. These include informing the development and refinement of subtypes of hallucinations within and across diagnostic categories; “front-loading” research in cognitive neuroscience; and suggesting new possibilities for therapeutic intervention. In conclusion, we argue that an interdisciplinary approach to the phenomenology of AVH can nourish the ethical core of scientific enquiry by challenging its interpretive paradigms, and offer voice hearers richer, potentially more empowering ways to make sense of their experiences.

Individual attributes, such as educational background, may influence the degree of health consideration in food consumption. The local social norms may affect the same consideration in the collective level. Represented by education level and the custom rules adherence in food choosing behavior, this study aimed to examine how knowledge influences health consideration in food consumption and how the local social norms moderate this association in a multicultural enriched society. By utilizing the Bayesian Mindsponge Framework (BMF) as a conceptual framework, this (...) study analyzed a dataset of 710 urban residents in Indonesia. There was a negative association between education level and health consideration in food consumption in which the custom rules adherence in food choosing behavior moderated against this negative association. For those with a low level of custom-based food consumption, their health consideration is lower as they have higher education level. However, the opposite trend which is a more intuitive positive association was found in those who consume more custom-based food. Socio-cultural factors have a complex impact on food choosing behavior among Indonesian urban residents. Therefore, governmental policies in the health promotion campaign of healthy-nutritious food should incorporate socio-cultural aspects with a deeper understanding of the human mind’s information processing.

In this short survey article, I discuss Bell’s theorem and some strategies that attempt to avoid the conclusion of non-locality. I focus on two that intersect with the philosophy of probability: (1) quantum probabilities and (2) superdeterminism. The issues they raised not only apply to a wide class of no-go theorems about quantum mechanics but are also of general philosophical interest.

I demonstrate that Bell's theorem is based on circular reasoning and thus a fundamentally flawed argument. It unjustifiably assumes the additivity of expectation values for dispersion-free states of contextual hidden variable theories for non-commuting observables involved in Bell-test experiments, which is tautologous to assuming the bounds of ±2 on the Bell-CHSH sum of expectation values. Its premises thus assume in a different guise the bounds of ±2 it sets out to prove. Once this oversight is ameliorated from (...) Bell's argument by identifying the impediment that leads to it and local realism is implemented correctly, the bounds on the Bell-CHSH sum of expectation values work out to be ±2√2 instead of ±2, thereby mitigating the conclusion of Bell's theorem. Consequently, what is ruled out by any of the Bell-test experiments is not local realism but the linear additivity of expectation values, which does not hold for non-commuting observables in any hidden variable theories to begin with. I also identify similar oversight in the GHZ variant of Bell's theorem, invalidating its claim of having found an inconsistency in the premisses of the argument by EPR for completing quantum mechanics. Conceptually, the oversight in both Bell's theorem and its GHZ variant traces back to the oversight in von Neumann's theorem against hidden variable theories identified by Grete Hermann in the 1930s.

What can be more fascinating than experimental metaphysics, to quote one of Abner Shimony’s enlightening expressions? Bell inequalities are at the heart of the study of nonlocality. I present a list of open questions, organised in three categories: fundamental; linked to experiments; and exploring nonlocality as a resource. New families of inequalities for binary outcomes are presented.

Bell’s theorem has fascinated physicists and philosophers since his 1964 paper, which was written in response to the 1935 paper of Einstein, Podolsky, and Rosen. Bell’s theorem and its many extensions have led to the claim that quantum mechanics and by inference nature herself are nonlocal in the sense that a measurement on a system by an observer at one location has an immediate effect on a distant entangled system. Einstein was repulsed by such “spooky action at a (...) distance” and was led to question whether quantum mechanics could provide a complete description of physical reality. In this paper I argue that quantum mechanics does not require spooky action at a distance of any kind and yet it is entirely reasonable to question the assumption that quantum mechanics can provide a complete description of physical reality. The magic of entangled quantum states has little to do with entanglement and everything to do with superposition, a property of all quantum systems and a foundational tenet of quantum mechanics.

This three-part paper comprises: (i) a critique by Halvorson of Bell’s (1973) paper ‘Subject and Object’; (ii) a comment by Butterfield; (iii) a reply by Halvorson. An Appendix gives the passage from Bell that is the focus of Halvorson’s critique.

The meaning of Lorentz contraction in special relativity and its connection with Bell’s spaceships parable is discussed. The motion of Bell’s spaceships is then compared with the accelerated motion of a rigid body. We have tried to write this in a simple form that could be used to correct students’ misconceptions due to conflicting earlier treatments.

Book review of "The Evil Within: Why we need Moral Philosophy", by Diane Jeske.

In recent work Mary Kate McGowan presents an account of oppressive speech inspired by David Lewis's analysis of conversational kinematics. Speech can effect identity-based oppression, she argues, by altering 'the conversational score', which is to say, roughly, that it can introduce presuppositions and expectations into a conversation, and thus determine what sort of subsequent conversational 'moves' are apt, correct, felicitous, etc., in a manner that oppresses members of a certain group (e.g. because the suppositions and expectations derogate or demean members (...) of that group). In keeping with the Lewisian picture, McGowan stresses the asymmetric pliability of conversational scores. She argues that it is easier to introduce (for example) sexist presuppositions and expectations into a conversation than it is to remove them. Responding to a sexist remark, she thus suggests, is like trying to "unring a bell". I begin by situating McGowan's work in the wider literature on speech and social hierarchy, and explaining how her account of oppressive speech improves upon the work of others in its explication of the relationship between individuals' verbal conduct and structurally oppressive social arrangements. I then propose an explanation and supportive elaboration of McGowan's claims about the asymmetric pliability of conversations involving identity-oppressive speech. Rather than regarding such asymmetry as a sui generis phenomenon, I show how we can understand it as a consequence of a more general asymmetry between making things salient and un-salient in speech, and I show how this asymmetry also operates in various cases that interested Lewis.

Clive Bell was not an ethicist. He was an aesthetician, known for his very strong formalist views, according to which art has nothing to do with ethics and politics. At least that is the textbook description of his general stance. ‘Art and war’ is a relatively unknown piece by him that has been ignored within art history partly because the relation between art on the one hand and ethics and politics on the other is much more complex here.

We show that the respective oversights in the von Neumann's general theorem against all hidden variable theories and Bell's theorem against their local-realistic counterparts are homologous. When latter oversight is rectified, the bounds on the CHSH correlator work out to be ±2√2 instead of ±2.

I point out a sign mistake in the GHZ variant of Bell's theorem, invalidating the GHZ's claim that the premisses of the EPR argument are inconsistent for systems of more than two particles in entangled quantum states.

She decided at last that the persecution of his presence was to be preferred to the persecution of his absence."Murdoch's novel (...) The Bell is about Imber Court. It is a small Anglican religious community of lay people whose lives were transformed, not just by the arrival of a couple of dissimilar visitors, not just by the arrival of a new bell to be installed at Imber Abbey located beyond the lake, but more significantly by the discovery of a centuries-old bell the story of which is engulfed in a terrible legend.

This book is devoted to the presentation of the new quantum mechanical formalism based on the probability representation of quantum states. In the 20s and 30s it became evident that some properties in quantum mechanics can be assigned only to the quantum mechanical system, but not necessarily to its constituents. This led Einstein, Podolsky and Rosen (EPR) to their remarkable 1935 paper where they concluded that quantum mechanics is not a complete theory of nature (EPR paradox). In order to avoid (...) the contradiction which arises from instantaneous action at a distance mentioned above we introduce an extension of the canonical relativity by using measure algebra of physical events in Minkowski space-time. The canonical QM formalism is extended by additional new postulate of EPRB nonlocality for continuous and discrete observables, chapter I. The postulate of EPRB nonlocality is supported by new quantum mechanical formalism based on the probability representation of quantum states. Chapter II is devoted to the new quantum mechanical formalism based on the probability representation of quantum states. Chapter III is devoted to the Einstein's 1927 gedanken experiment resolution. Chapter IV is devoted to the EPR paradox resolution. Chapter V is devoted to the EPR-B paradox resolution. Chapter VI is devoted to the Schrödinger's cat (measured spin) paradox resolution. Chapter VII is devoted to the Bell inequalities revisited. Remind that the canonical arguments which were presented by many authors, namely, that violations of Bell type inequalities signal us that the classical Kolmogorovian model of probability is inapplicable to quantum phenomena. We claimed that the canonical assumption, under which Bell type inequalities were derived, is not supported by real physical nature of the EPRB experiments. The fundamental physical nature violations of the canonical Bell type inequalities explained by Postulate of EPR-Nonlocality and Heisenberg noise-disturbance uncertainty relations. (shrink)

Bell inequalities are usually derived by assuming locality and realism, and therefore violations of the Bell-CHSH inequality are usually taken to imply violations of either locality or realism, or both. But, after reviewing an oversight by Bell, in the Corollary below we derive the Bell-CHSH inequality by assuming only that Bob can measure along vectors b and b' simultaneously while Alice measures along either a or a', and likewise Alice can measure along vectors a and a' (...) simultaneously while Bob measures along either b or b', without assuming locality. The violations of the Bell-CHSH inequality therefore only mean impossibility of measuring along b and b' simultaneously. (shrink)

We discuss models that attempt to provide an explanation for the violation of Bell inequalities at a distance in terms of hidden influences. These models reproduce the quantum correlations in most situations, but are restricted to produce local correlations in some configurations. The argument presented in (Bancal et al. Nat Phys 8:867, 2012) applies to all of these models, which can thus be proved to allow for faster-than-light communication. In other words, the signalling character of these models cannot remain (...) hidden. (shrink)
