The question of whether Everettian quantum mechanics (EQM) justifies the existence of metaphysical indeterminacy has recently come to the fore. Metaphysical indeterminacy has been argued to emerge from three sources: coherent superpositions, the indefinite number of branches in the quantum multiverse and the nature of these branches. This paper reviews the evidence and concludes that those arguments don’t rely on EQM alone and rest on metaphysical auxiliary assumptions that transcend the physics of EQM. We show how EQM can be ontologically (...) interpreted without positing metaphysical indeterminacy by adopting a deflationary attitude towards branches. Two ways of developing the deflationary view are then proposed: one where branches are eliminated, and another where they are reduced to the universal quantum state. (shrink)

A growing literature is premised on the claim that quantum mechanics provides evidence for metaphysical indeterminacy. But does it? None of the currently fashionable realist interpretations involve fundamental indeterminacy and the ‘standard interpretation’, to the extent that it can be made out, doesn't require indeterminacy either.

The Intellectualist thesis that know-how is a kind of propositional knowledge faces a simple problem: For any proposition p, it seems that one could know p without knowing how to do the activity in question. For example, it seems that one could know that w is a way to swim even if one didn't know how to swim oneself. In this paper I argue that this “sufficiency problem” cannot be adequately addressed by appealing to practical modes of presentation.

QBism is an agent-centered interpretation of quantum theory. It rejects the notion that quantum theory provides a God’s eye description of reality and claims instead that it imposes constraints on agents’ subjective degrees of belief. QBism’s emphasis on subjective belief has led critics to dismiss it as antirealism or instrumentalism, or even, idealism or solipsism. The aim of this paper is to consider the relation of QBism to scientific realism. I argue that while QBism is an unhappy fit with a (...) standard way of thinking about scientific realism, an alternative conception I call “perspectival normative realism” may allow for a reconciliation.

Anti-Intellectualists about know-how , following Ryle, hold that knowing how to do something is simply having the ability to do it. With qualifications, I defend this traditional view. The central motivation is drawn from observations about what is involved in learning to do something. Two sorts of ability are distinguished and the thesis is defended against putative counterexamples.

An account of the distinction between singular and general propositions should reflect the core ideas that have motivated the distinction. Those core ideas can be appreciated independently of many commitments regarding the metaphysics of propositions, but theorists with differing views on the latter have given quite different explanations of what it is for a proposition to be singular or general. Many of those explanations turn out not to reflect the core ideas adequately after all, either by misclassifying certain propositions or (...) by failing to be sufficiently informative. A more satisfactory account can be formulated by more directly elaborating on the background ideas motivating the distinction. The resulting account not only does better than its competitors, but is compatible with various views on the metaphysics of propositions. (shrink)

Metaphysical indeterminacy in the context of quantum mechanics is often motivated by the eigenstate-eigenvalue link. However, the sparse view of Glick illustrates why it has no such implications. Other links connecting quantum states and property ascriptions—such as those associated with the GRW theory—may introduce indeterminacy, but such indeterminacy may be viewed as merely representational and is susceptible to familiar treatments of vagueness. Thus, I contend that such links fail to provide a compelling motivation for quantum metaphysical indeterminacy.

In this paper I elicit a prediction from structural realism and compare it, not to a historical case, but to a contemporary scientific theory. If structural realism is correct, then we should expect physics to develop theories that fail to provide an ontology of the sort sought by traditional realists. If structure alone is responsible for instrumental success, we should expect surplus ontology to be eliminated. Quantum field theory (QFT) provides the framework for some of the best confirmed theories in (...) science, but debates over its ontology are vexed. Rather than taking a stand on these matters, the structural realist can embrace QFT as an example of just the kind of theory SR should lead us to expect. Yet, it is not clear that QFT meets the structuralist's positive expectation by providing a structure for the world. In particular, the problem of unitarily inequivalent representations threatens to undermine the possibility of QFT providing a unique structure for the world. In response to this problem, I suggest that the structuralist should endorse pluralism about structure. (shrink)

Experiments involving delayed-choice entanglement swapping seem to suggest that particles can become entangled after they’ve already been detected. This astonishing result is taken by some to undermine realism about entanglement. In this paper, I argue that one can offer a fully realist explanation of delayed-choice entanglement swapping by countenancing timelike entanglement relations. I argue that such an explanation—radical though it may be—isn’t incoherent and doesn’t invite paradox. I compare this approach to the antirealist alternative and a more deflationary realist strategy (...) defended by Egg, each of which face certain challenges. The upshot is that we should take seriously the possibility of timelike entanglement and seek to develop a framework for quantum theory which allows for it. (shrink)

Ontic structural realism claims that all there is to the world is structure. But how can this slogan be turned into a worked-out metaphysics? Here I consider one potential answer: a metaphysical framework known as ‘generalism’. According to the generalist, the most fundamental description of the world is not given in terms of individuals bearing properties, but rather, general facts about which states of affairs obtain. However, I contend that despite several apparent similarities between the positions, generalism is unable to (...) capture the two main motivations for OSR.

Quantum entanglement has long been thought to be have deep metaphysical consequences. For example, it has been claimed to show that Humean supervenience is false or to involve a novel form of ontological holism. One way to avoid confronting the metaphysical consequences is to adopt some form of antirealism. In this paper we discuss two prominent strands in recent literature—wavefunction realism and “Super-Humeanism”—that appear quite different, but, as we see it, are instances of a more general strategy. In effect, what (...) these attempt to do is to diffuse the puzzle of entanglement by eliminating it. These interpretative movements are advertised as equally realist, but, we claim, fail to take an appropriately realist attitude towards entanglement. What we advocate instead is a genuine metaphysics of entanglement: instead of eliminating entanglement, develop a metaphysics that accounts for and explains it. (shrink)

Ontic structural realism (OSR) claims that all there is to the world is structure. But how can this slogan be turned into a worked-out metaphysics? Here I consider one potential answer: a metaphysical framework known as generalism (Dasgupta, 2009, 2016). According to the generalist, the most fundamental description of the world is not given in terms of individuals bearing properties, but rather, general facts about which states of affairs obtain. However, I contend that despite several apparent similarities between the positions, (...) generalism is unable to capture the two main motivations for OSR. I suggest instead that OSR should be construed as a meta-metaphysical position. (shrink)

In this volume, written in honour of the eightieth birthday of Professor Shimon Glick, world renowned experts in the field of medical ethics struggle with the question of how to weigh the respective values of autonomy, altruism and authority in dealing with real life bioethical dilemmas.

From the feminist ‘sex wars’ of the 1980s to the queer theory and politics of the 1990s, debates about the politics of sexuality have been at the forefront of contemporary theoretical, social, and political demands. This article seeks to intervene in these debates by challenging the terms through which they have been defined. Investigating the importance of ‘sex positivity’ and transgression as conceptual features of feminist and queer discourses, this essay calls for a new focus on the political and material (...) effects of pro-sexuality.

The author congratulates Dr Brian Hurwitz, who recently reported the successful “intimidation” of an elderly competent widow into accepting badly needed therapy for a huge ulcerated carcinoma. He reports approvingly of the Israeli Patients' Rights Law, enacted in 1996, which demands detailed informed consent from competent patients before permitting treatment. But the law also provides an escape clause which permits coercing a competent patient into accepting life-saving therapy if an ethics committee feels that if treatment is imposed the patient will (...) give his/her consent retroactively. He suggests this approach as an appropriate middle road between overbearing paternalism and untrammelled autonomy. (shrink)

Worrall :99–124, 1989) famously claimed that structural realism is the best of both worlds; it enables one to endorse the best arguments for scientific realism and antirealism. In this paper, I argue that structural realism also enables one to combine two other seemingly inconsistent positions: realism and pluralism. Indeed, the very features which form the basis of the structural realist’s reply to the problem of theory change may be applied synchronically to allow for a pluralist structural realism. The resulting position (...) incorporates a robust variety of scientific pluralism unavailable to the traditional realist and thereby allows the structural realist to take seriously the pluralism apparent in scientific practice.

The author, a physician, rejects a previous defence of a doctors' strike. There is little justification for strikes in general, still less for doctors' strikes, he claims. Should not doctors rather 'stand above the common herd' and set an example, he asks. Furthermore the whole idea of strikes in which a third and innocent party is deliberately punished in order to apply pressure on someone else is a 'a bizarre ethic indeed' and not to his knowledge justified under any ethical (...) theory.

The ways in which space-time points and elementary particles are modeled share a curious feature: neither seems to specify which basic object has which properties. This chapter sketches the motivation for this claim and searches for an explanation for it. After reviewing several proposals, it argues for a view according to which objects occupy their place in a given relational structure essentially. This view, which is termed minimal structural essentialism, provides a metaphysical grounding for the physical equivalence of models related (...) by permutation. An interesting consequence of this position is that space-time points and elemental particles turn out to be individuals, albeit of a rather different sort than has traditionally been considered.

Consecutive measurements performed on the same quantum system can reveal fundamental insights into quantum theory’s causal structure, and probe different aspects of the quantum measurement problem. According to the Copenhagen interpretation, measurements affect the quantum system in such a way that the quantum superposition collapses after each measurement, erasing any memory of the prior state. We show here that counter to this view, un-amplified measurements have coherent ancilla density matrices that encode the memory of the entire set of quantum measurements (...) that came before, and that the chain of this entire set is therefore non-Markovian. In contrast, sequences of amplified measurements are equivalent to a quantum Markov chain. We argue that the non-Markovian nature of quantum measurement has empirical consequences that are incompatible with the assumption of wave function collapse, thus elevating the collapse assumption into a testable hypothesis. Finally, we find that all of the information necessary to reconstruct an arbitrary non-Markovian quantum chain of measurements is encoded on the boundary of that chain, reminiscent of the holographic principle.

Teaching medical ethics to medical students in a pluralistic society is a challenging task. Teachers of ethics have obligations not just to teach the subject matter but to help create an academic environment in which well motivated students have reinforcement of their inherent good qualities. Emphasis should be placed on the ethical aspects of daily medical practice and not just on the dramatic dilemmas raised by modern technology. Interdisciplinary teaching should be encouraged and teaching should span the entire duration of (...) medical studies. Attention should be paid particularly to ethical problems faced by the students themselves, preferably at the time when the problems are most on the students' minds. A high level of academic demands, including critical examination of students' progress is recommended. Finally, personal humility on the part of teachers can help set a good example for students to follow. (shrink)

I shared Raanan Gillon’s1 surprise at Robert Veatch’s criticism of the white coat ceremonies,2 and I think that the points raised by Veatch were quite adequately countered by Gillon’s response. The provocative points raised by Veatch do stimulate some valuable critical thinking about the process, although I think Veatch was carried away a bit by hyperbole. To label the drama of the ceremony as “ominous” goes a bit far by any criterion.I should like to describe an oath taking initiation ceremony (...) in use at the Ben Gurion University Faculty of Health Sciences for almost three decades, its history, features, current practice, and conclusions. I believe that Veatch’s specific objections are addressed by our process and merit consideration by other institutions as well.When the medical school was founded in 1974 the then dean , Professor Moshe Prywes, met with the just entering class several weeks before the onset of the academic year during a summer preliminary orientation period . Professor Prywes, an imaginative, charismatic innovator with a flair for public relations and the dramatic, suggested to the entering class that they take the physician’s oath during the first weeks of the academic year, coinciding with their first exposure to patients . He explained that he wanted the students to regard themselves as already bearing responsibilities and duties, and not just rights. He saw them as “change agents” working to upgrade the medical care and the health of the patients and community, right from the first days of their schooling.I had just arrived in Israel as a new immigrant to assume the foundation professorship of medicine, coming from ….

Some philosophers have attempted to utilize the conceptual tools of ethics in order to understand epistemology. One instantiation of this understands justification in terms of having a certain kind of epistemic right, namely, a right to believe. In variations of this theme, some hold that justification involves having the authority to believe, or being entitled to believe. But by examining the putative analogies between different versions of rights and justification, I demonstrate that justification should not be understood as having a (...) right to believe. (shrink)

The recent essay by Schuklenk and Smalling opposing respect for physicians’ conscientious objections to providing patients with medical services that are legally permitted in liberal democracies is based on several erroneous assumptions. Acting in this manner would have serious harmful effects on the ethos of medicine and of bioethics. A much more nuanced and balanced position is critical in order to respect physicians’ conscience with minimal damage to patients’ rights.

The principle of least action (PLA) has often been cited as a counterexample to the dominant mode of causal explanation in physics. In particular, PLA seems to involve an appeal to final causes or some other teleological ideology. However, Ben-Menahem (Causation in science, Princeton University Press, Princeton, 2018) argues that such implications no longer apply given that PLA can be recovered as limiting case from quantum theory. In this paper, I argue that the metaphysical implications of PLA-based explanations are not (...) undermined by its status as derivative. However, I contend that PLA functions as a diachronic constraint that licenses explanations by constraint (Lange, Because without cause: non-casual explanations in science and mathematics. Oxford University Press, Oxford, 2016). PLA-based explanations, on this account, are non-causal but also differ from familiar cases of teleological explanations in several respects. (shrink)

Experiments demonstrating entanglement swapping have been alleged to challenge realism about entanglement. Seevinck claims that entangle- ment “cannot be considered ontologically robust” while Healey claims that entanglement swapping “undermines the idea that ascribing an entangled state to quantum systems is a way of representing some new, non-classical, physical relation between them.” My aim in this paper is to show that realism is not threatened by the possibility of entanglement swapping, but rather, it should be informed by the phenomenon. I argue—expanding (...) the argument of Timpson and Brown —that ordinary entanglement swapping cases present no new challenges for the realist. With respect to the delayed-choice variant discussed by Healey, I claim that there are two options available to the realist: deny these are cases of genuine swapping ) or allow for existence of entanglement between timelike separated regions. This latter option, while radical, is not incoherent and has been suggested in quite different contexts. While I stop short of claiming that the realist must take this option, doing so allows one to avoid certain costs associated with Egg’s “orthodox” account. I conclude by noting several important implication of entanglement swapping for how one thinks of entanglement generally. (shrink)

Are space and time fundamental features of our world or might they emerge from something else? The Foundation of Reality brings together metaphysicians and philosophers of physics working on space, time, and fundamentality to address this timely question.

COPII coated vesicles bud from an ER domain termed the transitional ER (tER), but the mechanism that clusters COPII vesicles at tER sites is unknown. tER sites are closely associated with early Golgi or pre‐Golgi structures, suggesting that the clustering of nascent COPII vesicles could be achieved by tethering to adjacent membranes. This model challenges the prevailing view that COPII vesicles are clustered by a scaffolding protein at the ER surface. Although Sec16 was proposed to serve as such a scaffolding (...) protein, recent data suggest that rather than organizing COPII into higher‐order structures, Sec16 acts at the level of individual COPII vesicles to regulate COPII turnover. A plausible synthesis is that tER sites are created by tethering to Golgi membranes and are regulated by Sec16. Meanwhile, the COPII vesicles that bud from tER sites are thought to nucleate new Golgi cisternae. Thus, an integrated self‐organization process may generate tER‐Golgi units. (shrink)

In all the Alien films, the environments are gloomy settings originally inspired by Gothic architecture, but it's the creature design, which leaves the most profound mark on us. The interaction between these art‐horror monsters and the sterileturned‐ grotesque environments of the Alien films can produce disgust or revulsion in the viewer. In Alien a fair amount of time is spent on the relationships between the crew members. One of the most horrific moments of the series is the cry of “kill (...) me” that emerges from the half‐conscious hosts as the space Marines explore the former colony of Hadley's Hope. Central to Carroll's theory on art‐horror is revulsion at the suggestion of physical contact with the fusion‐figures. At the end of Alien: Resurrection, Ripley lies in the middle of the Queen's huge mass. It is the most striking image in an otherwise cartoonish film. (shrink)

I was deeply moved and inspired by Jason Dubroff’s article1 objecting to the source of the white coat distributed to the entering medical students at his school. The article stimulated me to ponder its implications and led to some thoughtful discussions with colleagues.

However, unlike many (...) of us who notice evidence of ethical insensitivity, react with a sigh or a comment, and go on with our lives without significant alteration in our normal activities, Jason initiated an investigation of the issue, researched it in his own time, and even proposed remedial actions—a remarkable, unusual and impressive course of events. His article reinforced some of my personal prejudices. To those of my colleagues who nostalgically bewail the alleged decrease in idealism in today’s entering medical students, I can point to Jason as an example of the kind of ethical sensitivity, ….

In the last few decades, residency in some of the world’s desired destination cities has become a privilege, as housing supply has not kept pace with population growth. This has led to a significant rise in housing prices and consequently to the exclusion of middle- and low-income populations on a large scale. These developments have received only scant attention in political theory despite their prominence in local policymaking and their contribution to processes of redrawing the boundaries of inclusion into local (...) political communities. My focus in this article is on the question ‘is it morally permissible for cities to sort members by economic means, and grant the better-off privileged access to residency?’ I explore this question by examining the main arguments used to support the city’s right to selectively admit would-be members. This allows me to delineate the limitations of the city’s general duty to be accessible to all segments of society and to present particular cases where the city has special obligations to incorporate nonmembers.
