Background At the beginning of the coronavirus (Covid-19) pandemic, many non-Covid healthcare services were suspended. In April 2020, the Department of Health in England mandated that non-Covid services should resume, alongside the continuing pandemic response. This ‘resetting’ of healthcare services created a unique context in which it became critical to consider how ethical considerations did (and should) underpin decisions about integrating infection control measures into routine healthcare practices. We draw on data collected as part of the ‘NHS Reset Ethics’ project, (...) which explored the everyday ethical challenges of resetting England’s NHS maternity and paediatrics services during the pandemic. Methods Healthcare professionals and members of the public participated in interviews and focus group discussions. The qualitative methods are reported in detail elsewhere. The focus of this article is our use of Frith’s symbiotic empirical ethics methodology to work from our empirical findings towards the normative suggestion that clinical ethics should explicitly attend to the importance of relationships in clinical practice. This methodology uses a five-step approach to refine and develop ethical theory based on a naturalist account of ethics that sees practice and theory as symbiotically related. Results The Reset project data showed that changed working practices caused ethical challenges for healthcare professionals, and that infection prevention and control measures represented harmful barriers to the experience of receiving and offering care. For healthcare professionals, offering care as part of a relational interaction was an ethically important dimension of healthcare delivery. Conclusions Our findings suggest that foregrounding the importance of relationships across a hospital community will better promote the ethically important multi-directional expression of caring between healthcare professionals, patients, and their families. We offer two suggestions for making progress towards such a relational approach. First, that there is a change of emphasis in clinical ethics practice to explicitly acknowledge the importance of the relationships (including with their healthcare team) within which the patient is held. Second, that organisational decision-making should take into account the moral significance afforded to caring relationships by healthcare professionals, and the role such relationships can play in the negotiation of ethical challenges.

Aiming to unravel the mystery of quantum mechanics, this book is concerned with questions about action-at-a-distance, holism, and whether quantum mechanics gives a complete account of microphysical reality. With rigorous arguments and clear thinking, the author provides an introduction to the philosophy of physics.

We extend the work of French and Redhead [1988] further examining the relation of quantum statistics to the assumption that quantum entities have the sort of identity generally assumed for physical objects, more specifically an identity which makes them susceptible to being thought of as conceptually individuatable and labelable even though they cannot be experimentally distinguished. We also further examine the relation of such hypothesized identity of quantum entities to the Principle of the Identity of Indiscernibles. We conclude that (...) although such an assumption of identity is consistent with the facts of quantum statistics, methodological considerations show that we should take quantum entities to be entirely unindividuatable, in the way suggested by a Fock space description.

This book concentrates on research done during the last twenty years on the philosophy of quantum mechanics. In particular, the author focuses on three major issues: whether quantum mechanics is an incomplete theory, whether it is non-local, and whether it can be interpreted realistically. Much of the book is concerned with distinguishing various senses in which these questions can be taken, and assessing the bewildering variety of answers philosophers and physicists have given up to now. The book is self-contained in (...) that it presents the necessary parts of the mathematical formalism of quantum mechanics and also covers other interpretative topics, such as the problem of measurement and the uncertainty relations. A considerable portion of the book is based on original arguments presented by the author in lectures and research papers over the past ten years. However, this material is integrated with a broad coverage of most of the recent research in the field, so as to provide a balanced introduction to the whole subject. (shrink)

The book is drawn from the Tarner lectures, delivered in Cambridge in 1993. It is concerned with the ultimate nature of reality, and how this is revealed by modern physical theories such as relativity and quantum theory. The objectivity and rationality of science are defended against the views of relativists and social constructionists. It is claimed that modern physics gives us a tentative and fallible, but nevertheless rational, approach to the nature of physical reality. The role of subjectivity in science (...) is examined in the fields of relativity theory, statistical mechanics and quantum theory, and recent claims of an essential role for human consciousness in physics is rejected. Prospects for a 'Theory of Everything' are considered, and the related question of how to assess scientific progress is carefully examined. (shrink)

In this paper questions about vacuum fluctuations in local measurements, and the correlations between such fluctuations, are discussed. It is shown that maximal correlations always exist between suitably chosen local projection operators associated with spacelike separated regions of space-time, however far apart these regions may be. The connection of this result with the well-known Fregenhagen bound showing exponential decay of correlations with distance is explained, and the relevance of the discussion to the question “What do particle detectors detect?” is addressed.

Hume famously warned us that the ‘[The] ultimate springs and principles are totally shut up from human curiosity and enquiry’. Or, again, Newton: ‘Hitherto I have not been able to discover the cause of these properties of gravity … and I frame no hypotheses.’ Aristotelian science was concerned with just such questions, the specification of occult qualities, the real essences that answer the question What is matter, etc?, the preoccupation with circular definitions such as dormative virtues, and so on. The (...) rise of modern science is usually seen as a break with the sterility of Aristotelianism, so what exactly is it that modern science does discover, if it is not the essential nature of matter, of force, of energy, of space and time? A famous answer was provided by Poincaré: ‘The true relations between these real objects are the only reality we can attain.’ This is often regarded as the manifesto of so-called structural realism, as espoused in recent years by John Worrall, for example ). In response to the arguments of Larry Laudan against convergent realism, Worrall points to the continuity in the formal relations between elements of reality expressed by mathematical equations, while the intrinsic nature of these elements of reality gets constantly revised.

Over the past four decades, Charles Taylor's work as an intellectual historian, epistemologist, and normative political theorist has made him a leading figure in contemporary social philosophy. In Charles Taylor: Thinking and Living Deep Diversity, Mark Redhead examines the problem of political fragmentation, the problem of how to accommodate narrowly defined groups while promoting allegiance to a larger polity, through an analysis of Taylor's thought and politics.

The metaphysical commitments of quantum field theory are examined. A thesis of underdetermination as between field and particle approaches to the "elementary particles" is argued for but only if a disputed notion of transcendental individuality is admitted. The superiority of the field approach is further emphasized in the context of heuristics.

The status of the vacuum in relativistic quantum field theory is examined. A sharp distinction arises between the global vacuum and the local vacuum. The concept of local number density is critically assessed. The global vacuum state implies fluctuations for all local observables. Correlations between such fluctuations in space-like separated regions of space-time are discussed and the existence of correlations which are maximal in a certain sense is remarked on, independently of how far apart those regions may be. The analogy (...) with the mirror-image correlations in the singlet state of two spin-1/2 particles is explained. The connection between these maximal correlations and the well-known violation of the Bell inequality in the vacuum state is discussed, together with the way in which the existence of these correlations might be exploited in developing a vacuum version of the Einstein-Podolsky-Rosen argument. The recent relativistic formulation of the Einstein-Podolsky-Rosen argument by Ghirardi and Grassi is critically assessed with particular reference to the vacuum case. (shrink)

The paper is concerned with explaining some of the principal theoretical developments in elementary particle physics and discussing the associated methodological problems both in respect of heuristics and appraisal. Particular reference is made to relativistic quantum field theory, renormalization, Feynman diagram techniques, the analytic S-matrix and the Chew — Frautschi bootstrap.

Popper wrote extensively on the quantum theory. In Logic der Forschung he devoted a whole chapter to the topic, while the whole of Volume 3 of the Postscript to the Logic of Scientific Discovery is devoted to the quantum theory. This volume entitled Quantum Theory and the Schism in Physics incorporated a famous earlier essay, ‘Quantum Mechanics without “the Observer”’ . In addition Popper's development of the propensity interpretation of probability was much influenced by his views on the role of (...) probability in quantum theory, and he also wrote an insightful critique of the 1936 paper of Birkhoff and von Neumann on nondistributive quantum logic.

In Theoretical Times, Steve Redhead describes the post-crash economic, environmental, political and cultural condition we live in today. As the rise of the international right - Donald Trump, Brexit, Marine Le Pen - swarms the globe, a new global battle within the right is developing: the globalists and neo-liberals versus the economic nationalists and protectionists. What then are the prospects for a resurrected theoretical politics of the left? Theoretical Times considers the work of theorists such as Alain Badiou, Slavoj (...) Žižek, Jean Baudrillard and Paul Virilio, in this innovative reinvention of theory and the politics of theory. After the global financial crash the world is being hollowed out and we find ourselves in what Žižek calls a desperate state of hopelessness, the "new dark ages". Accelerated culture sees us digitally entertaining ourselves to death but leaves us exhausted and frightened waiting for World War Three. Theoretical Times offers new theoretical resources as a way out of the quicksand. (shrink)

In his paper, “Grand Unified Gauge Theories and the Number of Elementary Particles,“ Robert Weingard suggests what he calls the Extended Redhead's Principle for elementary particles: “Two particles for which there are conceivable circumstances in which one can be ‘rotated’ or reoriented into the other are the same particles”. The philosophical soundness of such a principle is questionable.

The bootstrap approach to understanding the elementary particles in hadronic physics was very popular in the 1960s as an alternative to quantum field theory. This episode is subjected to historical, methodological and philosophical analysis designed to complement the extensive work of Jim Cushing in this field.

In this article, I discuss Charles Taylor's reading of Nietzsche. Taylor argues that Nietzsche presents a challenge on the 'deepest level' because, on Taylor's reading, Nietzsche forces us to consider whether or not our 'continuing allegiance to standards of justice and benevolence' goes against our inner nature. I argue that this purported Nietzschean challenge is more self-revealing of Taylor than it is foreboding, as it brings to light the tension between the open and pluralistic content of Taylor's faith, and the (...) epistemological grounding of it, which a more well-rounded appreciation of Nietzsche could help to alleviate.

In what sense do the sciences explain? Or do they merely describe what is going on without answering why-questions at all. But cannot description at an appropriate ‘level’ provide all that we can reasonably ask of an explanation? Well, what do we mean by explanation anyway? What, if anything, gets left out when we provide a so-called scientific explanation? Are there limits of explanation in general, and scientific explanation, in particular? What are the criteria for a good explanation? Is it (...) possible to satisfy all the desiderata simultaneously? If not, which should we regard as paramount? What is the connection between explanation and prediction? What exactly is it that statistical explanations explain? These are some of the questions that have generated a very extensive literature in the philosophy of science. In attempting to answer them, definite views will have to be taken on related matters, such as physical laws, causality, reduction, and questions of evidence and confirmation, of theory and observation, realism versus antirealism, and the objectivity and rationality of science. I will state my own views on these matters, in the course of this essay. To argue for everything in detail and to do justice to all the alternative views, would fill a book, perhaps several books. I want to lead up fairly quickly to modern physics, and review the explanatory situation there in rather more detail. (shrink)

Granted that truth is valuable we must recognize that certifiable truth is hard to come by, for example in the natural and social sciences. This paper examines the case of mathematics. As a result of the work of Gödel and Tarski we know that truth does not equate with proof. This has been used by Lucas and Penrose to argue that human minds can do things which digital computers can't, viz to know the truth of unprovable arithmetical statements. The argument (...) is given a simple formulation in the context of sorites (Robinson) arithmetic, avoiding the complexities of formulating the Gödel sentence. The pros and cons of the argument are considered in relation to the conception of mathematical truth. (shrink)

Caroline New is an energetic activist who has interpolated critical realist ideas into the front-line of political activism. In this wide-ranging interview, she begins by reflecting on her life and how she became a realist and her account is illustrated with personal anecdotes recalling memories of well-known philosophers and activists from the time. She discusses how her position set her apart from other feminists and she examines the interacting threads of longstanding debates on the political left, as well as (...) longstanding debates within critical realist circles, such as the relative importance of quantitative methods in social research and the scope for agency as a source of intentional change. Finally she brings some of her ideas to bear on contemporary issues. This engaging interview notably provides some of the social context in which critical realism developed, while also pointing towards its future potential. (shrink)

The expansion of human rights provisions has produced an increasing number of human rights practitioners and delineated human rights as a field of its own. Questions of who is practicing human rights and how they practice it have become important. This paper considers the question of human rights practice and the agency of practitioners, arguing that practice should not be conceived as the application of philosophy, but instead approached from a sociological point of view. Whatever the structuring effect of political (...) institutions, human rights is being defined more expansively by practitioners. The weakness of international institutions and the interpretive scope of human rights discourse produce significant opportunity for practitioners to interpret the meaning of human rights. Our exploratory interviews of a small sample of practitioners reveal widely varying histories, in which they interpret their own work as “human rights” practice in differing ways. Practitioners who in the past thought of themselves differently, now identify as human rights activists. They are also becoming more professional, but concerned about professionalization. Their self-interpretations reflect these concerns and also respond to the necessities of career events. Through the conscious and unconscious aspects of their practice, practitioners exercise considerable agency in adapting human rights discourse to their own concerns while also being critical of it.

This article pursues two questions: Can one use Foucault’s later writings on parrhesia and Kant to create a Foucaldian approach to public reason? If so, what lessons might those attracted to John Rawls’ well-known model of public reason draw from a Foucaldian orientation? By putting Foucault into a competitive yet productive relationship with Rawls, this article addresses some of the latter’s shortcomings. In doing so it also makes a larger argument about the need to develop approaches to democratic deliberation that (...) involve engagement with – rather than simple toleration and/or accommodation of – the various ‘reasonable’ ethical commitments deliberators, on some fundamental level, reason in light of. The justificatory aims of public reason are best achieved when participants’ most-cherished beliefs are opened to critical dialogue rather than banished to the realm of the ‘non-political’. The article begins by briefly illuminating the salient features of Rawls’ model of public reasoning as well as three problems that ensue with the limitations it places on discourses regulated by public reason. It then attempts to distill a Foucaldian approach to public reason by briefly discussing 4 elements of Foucault’s later work on Rawls’ philosophical godfather Kant together with several features of the antiquarian studies of parrhesia that Foucault was conducting at the time these Kantian works were written. Third, Jeffrey Stout’s recent account of theistic democratic actors in some of the most economically disadvantaged US localities demonstrates how many of the ideals integral to this Foucaldian approach to public reasoning built on engaging (rather than simply tolerating and/or accommodating) contrasting ethical perspectives are central to some concrete practices of public reasoning. It concludes with some thoughts on the necessity of publicly reasoning through rather than independently of our deepest commitments. (shrink)

Recent discussions of experimental tests of the Sum Rule have been carried out in the context of the special circumstances attending the Cross-Ramsey experiment. A more general analysis of possible tests is presented. A technical mistake of Fine and Glymour concerned with a misunderstanding of the physics of the Cross-Ramsey experiment is explained and a detailed analysis of a thought experiment based on the Einstein-Podolsky-Rosen wave function is given. It is concluded, in agreement with Fine, that scattering experiments do not (...) test the Sum Rule as a principle which supplements standard quantum mechanics. (shrink)

Department of History and Philosophy of Science. University of Cambridge, Free School Lane, Cambridge CB2 3RH This paper is concerned with the question of whether atomic particles of the same species, i. e. with the same intrinsic state-independent properties of mass, spin, electric charge, etc, violate the Leibnizian Principle of the Identity of Indiscernibles, in the sense that, while there is more than one of them, their state-dependent properties may also all be the same. The answer depends on what exactly (...) the state-dependent properties of atomic particles are taken to be. On the plausible interpretation that these should comprise all monadic and relational properties that can be expressed in terms of physical magnitudes associated with self-adjoint operators that can be defined for the individual particles, then the weakest form of the Principle is shown to be violated for bosons, fermions and higher-order paraparticles, treated in first quantization *Some of the arguments inn this paper appeared in a thesis submited by one of us (S.F.) In partial fulfilment of the requirements for the PhD degree of the University of London, in 1984. entitled 'Identity and ‘Individuality in Classical and Quantum Physics’. (shrink)

Salient landmarks enhance route learning. We hypothesised that semantically salient nostalgic landmarks would improve route learning compared to non-nostalgic landmarks. In two experiments, participants learned a route through a computer-generated maze using directional arrows and wall-mounted pictures. On the test trial, the arrows were removed, and participants completed the maze using only the pictures. In the nostalgia condition, pictures were of popular music artists and TV characters from 5 to 10 years ago. In the control condition, they were recent pictures (...) of these same artists and characters. In Experiment 1, in the test trial, participants in the nostalgia condition completed the maze faster than controls. Experiment 2 conceptually replicated these findings and extended them by exploring boundary conditions. Participants had to learn two mazes sequentially. In Maze 1, we placed nostalgic/control landmarks only at non-decision points (whereas we placed them at decision points in Experiment 1). In Maze 2, we placed nostalgic/control landmarks at decision points during acquisition but removed them in the test trial (whereas they were present in the test trial in Experiment 1). In both mazes, participants in the nostalgia (compared to control) condition completed the test trial faster. (shrink)

This article focuses on Charles Taylor’s and William Connolly’s attempts to fashion alternative forms of secular public reasoning to those of liberals like Rawls and Galston. I provide a weak defense of Taylor against both Connolly and many of Taylor’s liberal secular foes. Despite its noted shortcomings that Connolly can help to address, Taylor’s model does provide a more adequate basis for thinking through a public morality appropriate to the times because it takes seriously the hold certain values have on (...) non-secular individuals, and thus is very much attuned to the realities of ethical deliberation in early 21st-century western democracies Key Words: democracy • liberalism • pluralism • secularism • theism.
