Relational quantum mechanics (RQM) is an interpretation of quantum mechanics based on the idea that quantum states do not describe an absolute property of a system but rather a relationship between systems. There have recently been some criticisms of RQM pertaining to issues around intersubjectivity. In this article, we show how RQM can address these criticisms by adding a new postulate which requires that all of the information possessed by a certain observer is stored in physical variables of that observer (...) and thus is accessible by measurement to other observers. This makes it possible for observers to reach intersubjective agreement about quantum events that have occurred in the past. We suggest a possible ontology for a version of RQM employing this postulate; this ontology upholds the principle that quantum states are always relational, but it also postulates a set of quantum events that are not strictly relational. We show that the new postulate helps address the preferred basis problem in RQM. (shrink)

The laws of nature have come a long way since the time of Newton: quantum mechanics and relativity have given us good reasons to take seriously the possibility of laws which may be non-local, atemporal, ‘all-at-once,’ retrocausal, or in some other way not well-suited to the standard dynamical time evolution paradigm. Laws of this kind can be accommodated within a Humean approach to lawhood, but many extant non-Humean approaches face significant challenges when we try to apply them to laws outside (...) the time evolution picture. Thus for proponents of non-Humean approaches to lawhood there is a clear need for a novel non-Humean account which is capable of accommodating these sorts of laws. In this paper we propose such an account, characterizing lawhood in terms of constraints, which are understood as a form of modal structure. We demonstrate that our proposed realist account can indeed accommodate a large variety of laws outside the time evolution paradigm, and describe some possible applications to important philosophical problems.

Experiments are commonly thought to have epistemic privilege over simulations. Two ideas underpin this belief: first, experiments generate greater inferential power than simulations, and second, simulations cannot surprise us the way experiments can. In this article I argue that neither of these claims is true of experiments versus simulations in general. We should give up the common practice of resting in-principle judgments about the epistemic value of cases of scientific inquiry on whether we classify those cases as experiments or simulations, (...) per se. To the extent that either methodology puts researchers in a privileged epistemic position, this is context sensitive. (shrink)

There is an undeniable tendency to dismiss women’s sexual assault allegations out of hand. However, this tendency is not monolithic—allegations that black men have raped white women are often met with deadly seriousness. I argue that contemporary rape culture is characterized by the interplay between rape myths that minimize rape, and myths that catastrophize rape. Together, these two sets of rape myths distort the epistemic resources that people use when assessing rape allegations. These distortions result in the unjust exoneration of (...) people we cannot conceive of as monstrous, while making it too easy to believe that some marginalized people could be rapists. I also argue that rape myths enable a novel kind of epistemic injustice. This injustice concerns how our assessments of trustworthiness and our assessments of plausibility interact. I argue that rape myths can result in runaway credibility deflations that can explain both why people fail to believe most women, and also why people may unjustly believe false allegations that white women have been raped by black men.

Recently there have emerged an assortment of theorems relating to the ‘absoluteness of emerged events,’ and these results have sometimes been used to argue that quantum mechanics may involve some kind of metaphysically radical non-absoluteness, such as relationalism or perspectivalism. However, in our view a close examination of these theorems fails to convincingly support such possibilities. In this paper we argue that the Wigner’s friend paradox, the theorem of Bong et al and the theorem of Lawrence et al are all (...) best understood as demonstrating that if quantum mechanics is universal, and if certain auxiliary assumptions hold, then the world inevitably includes various forms of ‘disaccord,’ but this need not be interpreted in a metaphysically radical way; meanwhile, the theorem of Ormrod and Barrett is best understood either as an argument for an interpretation allowing multiple outcomes per observer, such as the Everett approach, or as a proof that quantum mechanics cannot be universal in the sense relevant for this theorem. We also argue that these theorems taken together suggest interesting possibilities for a different kind of relational approach in which _interaction_ states are relativized whilst observed events are absolute, and we show that although something like ‘retrocausality’ might be needed to make such an approach work, this would be a very special kind of retrocausality which would evade a number of common objections against retrocausality. We conclude that the non-absoluteness theorems may have a significant role to play in helping converge towards an acceptable solution to the measurement problem. (shrink)

Any successful interpretation of quantum mechanics must explain how our empirical evidence allows us to come to know about quantum mechanics. In this article, we argue that this vital criterion is not met by the class of ‘orthodox interpretations,’ which includes QBism, neo-Copenhagen interpretations, and some versions of relational quantum mechanics. We demonstrate that intersubjectivity fails in radical ways in these approaches, and we explain why intersubjectivity matters for empirical confirmation. We take a detailed look at the way in which (...) belief-updating might work in the kind of universe postulated by an orthodox interpretation, and argue that observers in such a universe are unable to escape their own perspective in order to learn about the structure of the set of perspectives that is supposed to make up reality according to these interpretations. We also argue that in some versions of these interpretations it is not even possible to use one’s own relative frequencies for empirical confirmation. Ultimately we conclude that it cannot be rational to believe these sorts of interpretations unless they are supplemented with some observer-independent structure which underwrites intersubjective agreement in at least certain sorts of cases.

Deception sometimes results in nonconsensual sex. A recent body of literature diagnoses such violations as invalidating consent: the agreement is not morally transformative, which is why the sexual contact is a rights violation. We pursue a different explanation for the wrongs in question: there is valid consent, but it is not consent to the sex act that happened. Semantic conventions play a key role in distinguishing deceptions that result in nonconsensual sex (like stealth condom removal) from those that don’t (like (...) white lies). Our framework is also applicable to more controversial cases, like those implicated in so-called “gender fraud” complaints. (shrink)

In recent years the quantum foundations community has seen increasing interest in the possibility of using retrocausality as a route to rejecting the conclusions of Bell’s theorem and restoring locality to quantum physics. On the other hand, it has also been argued that accepting nonlocality leads to a form of retrocausality. In this article we seek to elucidate the relationship between retrocausality and locality. We begin by providing a brief schema of the various ways in which violations of Bell’s inequalities (...) might lead us to consider some form of retrocausality. We then consider some possible motivations for using retrocausality to rescue locality, arguing that none of these motivations is sufficient to show that local retrocausal theories should always be preferred to nonlocal retrocausal theories, and therefore there is no clear reason to focus research efforts entirely on seeking local retrocausal models. Next, we examine several different conceptions of retrocausality, concluding that ‘all-at-once’ retrocausality is more coherent than the alternative dynamical picture. We then argue that since the ‘all-at-once’ approach requires probabilities to be assigned to entire histories, locality is not playing any crucial role within this picture. Thus we conclude that using retrocausality as a way to rescue locality may not be the right route to retrocausality. Finally, we demonstrate that accepting the existence of nonlocality and insisting on the nonexistence of preferred reference frames leads naturally to the acceptance of a form of retrocausality, albeit one which is not mediated by physical systems travelling backwards in time. We argue that this is the more natural way to motivate retrocausal models of quantum mechanics. (shrink)

Quantum mechanics is an extraordinarily successful scientific theory. But more than 100 years after it was first introduced, the interpretation of the theory remains controversial. This Element introduces some of the most puzzling questions at the foundations of quantum mechanics and provides an up-to-date and forward-looking survey of the most prominent ways in which physicists and philosophers of physics have attempted to resolve them. Topics covered include nonlocality, contextuality, the reality of the wavefunction and the measurement problem. The discussion is (...) supplemented with descriptions of some of the most important mathematical results from recent work in quantum foundations, including Bell's theorem, the Kochen-Specker theorem and the PBR theorem.

The growing block view of time holds that the past and present are real whilst the future is unreal; as future events become present and real, they are added on to the growing block of reality. Surprisingly, given the recent interest in this view, there is very little literature on its origins. This paper explores those origins, and advances two theses. First, I show that although C. D. Broad’s Scientific Thought provides the first defence of the growing block theory, the (...) theory receives its first articulation in Samuel Alexander’s Space, Time, and Deity. Further, Alexander’s account of deity inclines towards the growing block view. Second, I argue that Broad shifted towards the growing block theory as a result of his newfound conviction that time has a direction. By way of tying these theses together, I argue that Broad’s views on the direction of time – and possibly even his growing block theory – are sourced in Alexander. (shrink)

In this article we set out to understand the significance of the process matrix formalism and the quantum causal modelling programme for ongoing disputes about the role of causation in fundamental physics. We argue that the process matrix programme has correctly identified a notion of ‘causal order’ which plays an important role in fundamental physics, but this notion is weaker than the common-sense conception of causation because it does not involve asymmetry. We argue that causal order plays an important role (...) in grounding more familiar causal phenomena. Then we apply these conclusions to the causal modelling programme within quantum foundations, arguing that since no-signalling quantum correlations cannot exhibit causal order, they should not be analysed using classical causal models. This resolves an open question about how to interpret fine-tuning in classical causal models of no-signalling correlations. Finally we observe that a quantum generalization of causal modelling can play a similar functional role to standard causal reasoning, but we emphasize that this functional characterisation does not entail that quantum causal models offer novel explanations of quantum processes.

The COVID-19 pandemic has had a devastating impact on care homes in the United Kingdom, particularly for those residents living with dementia. The impetus for this article comes from a recent review conducted by the authors. That review, a qualitative media analysis of news and academic articles published during the first few months of the outbreak, identified ethical care as a key theme warranting further investigation within the context of the crisis. To explore ethical care further, a set of salient (...) ethical values for delivering care to care home residents living with dementia during the pandemic was derived from a synthesis of relevant ethical standards, codes and philosophical approaches. The ethical values identified were caring, non-maleficence, beneficence, procedural justice, dignity in death and dying, well-being, safety, and personhood. Using these ethical values as a framework, alongside examples from contemporaneous media and academic sources, this article discusses the delivery of ethical care to care home residents with dementia within the context of COVID-19. The analysis identifies positive examples of ethical values displayed by care home staff, care sector organisations, healthcare professionals and third sector advocacy organisations. However, concerns relating to the death rates, dignity, safety, well-being and personhood – of residents and staff – are also evident. These shortcomings are attributable to negligent government strategy, which resulted in delayed guidance, lack of resources and Personal Protective Equipment, unclear data, and inconsistent testing. Consequently, this review demonstrates the ways in which care homes are underfunded, under resourced and undervalued. (shrink)

In this article, I offer an analysis of what it is to take offense and what doing so is like, on which a more nuanced and positive appraisal of this emotion becomes possible as compared to its popular reputation. First, I survey the shortfalls of the limited discussion of offense by philosophers, before proposing an alternative analysis. Second, I distinguish offense from nearby emotions, like anger, disgust, and pride. Third, I examine the implications not only for how we conceptualize offense (...) but also how we regard those who take it. On my account, offense tends to be a smaller-scale, more everyday emotion than those making claims about its threats to society suppose, and one ripe for a moral reassessment. While offense sometimes appears excessive, that is likely only in limited cases: namely, those requiring symbolic withdrawal or proxy forms of estrangement. Even there, the appearance of excess may be illusory, with the grander gestures of offense appropriate given the distance between the offended and offending parties. Furthermore, on my account, to take offense is to resist affronts to one's standing, rather than merely a reflection of hurt feelings. Concluding, I sketch a defense of this resistance as a sometimes valuable response to injustice. (shrink)

I argue that the Oxford school Everett interpretation is internally incoherent, because we cannot claim that in an Everettian universe the kinds of reasoning we have used to arrive at our beliefs about quantum mechanics would lead us to form true beliefs. I show that in an Everettian context, the experimental evidence that we have available could not provide empirical confirmation for quantum mechanics, and moreover that we would not even be able to establish reference to the theoretical entities of (...) quantum mechanics. I then consider a range of existing Everettian approaches to the probability problem and show that they do not succeed in overcoming this incoherence. (shrink)

Aristotle claims that in making an animal, nature acts like a “good housekeeper” who “is accustomed to throw out nothing from which it is possible to make something useful” (744b16–17). How does nature act when it “make[s] something useful” in these cases – and does it differ from other ways it acts? I defend two main claims. The first is that Meteor. 4.2’s distinction between two sorts of ‘concoction’ processes offers an underappreciated source of evidence for answering this question. My (...) second claim concerns the nature of those processes and the ends they realize. While they are both the ends of their respective types of concoction, they differ in that some essential (process-defining) features of the second end – but not the first – are supplied by what the capacities of the “underlying” patient (on which the agent acts) are for. The result is a distinction between two kinds of end-directed efficient causation. (shrink)

Recently there has been a great deal of interest in tabletop experiments intended to exhibit the quantum nature of gravity by demonstrating that it can induce entanglement. In order to evaluate these experiments, we must determine if there is any interesting class of possibilities that will be convincingly ruled out if it turns out that gravity can indeed induce entanglement. In particular, since one argument for the significance of these experiments rests on the claim that they demonstrate the existence of (...) superpositions of spacetimes, it is important to keep in mind that different interpretations of quantum mechanics may make different predictions about superpositions of spacetimes. ψ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\psi$$\end{document}-complete interpretations of quantum mechanics, like the Everett interpretation, almost universally predict the existence of superpositions of spacetimes, whereas in ψ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\psi$$\end{document}-incomplete, ψ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\psi$$\end{document}-nonphysical interpretations it seems more natural to predict that spacetime superpositions are not possible.

There are two competing paradigms for the interpretation of these experiments, which have been dubbed the ‘Newtonian’ paradigm and the ‘tripartite’ paradigm: here we largely work within the tripartite paradigm, because the tripartite view is specifically concerned with ontological aspects of the mediating gravitational interaction and that makes it a suitable setting for enquiries about the ontology of quantum mechanics, but in Sect. 4 we consider what conclusions can be drawn if one does not presuppose the tripartite view. Finally in Sect. 5 we discuss a cosmological phenomenon which could be regarded as providing evidence for PIQG models. (shrink)

Many scholars have drawn attention to the way that elements of Anne Conway’s system anticipate ideas found in Leibniz. This paper explores the relationship between Conway and Leibniz’s work with regard to time, space, and process.

This exploration advances our (...) understanding of Conway’s system, and the intellectual relationships between Conway, More, and Leibniz. (shrink)

Children bring intuitive arithmetic knowledge to the classroom before formal instruction in mathematics begins. For example, children can use their number sense to add, subtract, compare ratios, and even perform scaling operations that increase or decrease a set of dots by a factor of 2 or 4. However, it is currently unknown whether children can engage in a true division operation before formal mathematical instruction. Here we examined the ability of 6- to 9-year-old children and college students to perform symbolic (...) and non-symbolic approximate division. Subjects were presented with non-symbolic or symbolic dividends ranging from 32 to 185, and non-symbolic divisors ranging from 2 to 8. Subjects compared their imagined quotient to a visible target quantity. Both children and adults were successful at the approximate division tasks in both dots and numeral formats. This was true even among the subset of children that could not recognize the division symbol or solve simple division equations, suggesting intuitive division ability precedes formal division instruction. For both children and adults, the ability to divide non-symbolically mediated the relation between Approximate Number System acuity and symbolic math performance, suggesting that the ability to calculate non-symbolically may be a mechanism of the relation between ANS acuity and symbolic math. Our findings highlight the intuitive arithmetic abilities children possess before formal math instruction. (shrink)

This essay explores how the distinctively anthropological concept of culture provides uniquely valuable insights into the workings of science in its cultural context. Recent efforts by anthropologists to dislodge the traditional notion of culture as a homogenous, stable whole have opened up a variety of ways of imagining culture that place power differentials, flux, and contradiction at its center. Including attention to a wide variety of social domains outside the laboratory, attending to the ways nonscientists actively engage with scientific knowledge, (...) and focusing on the complex interactions that flow both into and out of research laboratories are ways the activities of both scientists and nonscientists can be situated in the heterogeneous matrtx of culture. Three images—the citadel, the rhizome, and the string figure—allow us to picture the discontinuous ways science both permeates and is permeated by cultural life. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:IntroductionSpatial, Environmental, and Ecocritical Approaches to Holocaust MemoryEmily-Rose Baker (bio), Michael Holden (bio), Diane Otosaka (bio), Sue Vice (bio), and Dominic Williams (bio)The successful implementation of genocide during the Holocaust depended on the spatial organisation of mass murder. From the concentrated ghettos and camps delimited by walls and barbed wire to the open fields and camouflaged forests where victims were shot en masse, Anne Kelly Knowles et al. argue, (...) specific locations, patterns of migration, deportation and evacuation, and other spatial elements such as scale, were all central to the Nazi regime's creation of a "comprehensive geography of oppression."1 This is hardly surprising given the biopolitical logics and colonial fantasies underpinning Lebensraum ('living space'), the territorial concept guiding the genocidal aims of the Third Reich, which designated zones of life as well as the inverse on the European continent. The Holocaust was also experienced spatially by its victims, who were forced to navigate new (and at times familiar) sites and landscapes as those of genocide, and whose testimonies in the aftermath of the event conjured these very places in detail.In recent years, the spaces of the Holocaust have been variously revisited, reconstructed, and reimagined within Holocaust studies scholarship. As a broader part of the 'spatial turn' in the humanities, Holocaust scholars have increasingly employed spatial perspectives of the event to deepen our understanding of the environments in which the Holocaust took place and the transformation of these spaces over time—particularly in the fields of history and social science.2 While drawing on diverse modes of spatialisation from interdisciplinary perspectives, contributions from these fields have tended to privilege methods we might describe as variously 'forensic,' including mapping, model-making, and investigations of material traces of the past.3 This work has resulted in many significant insights, not only into the [End Page 1] contexts and structures of Nazi genocide and the perpetrator imaginings of space, but also the experiences of victims and survivors.4Another significant body of work has attended to space and culture within Holocaust contexts. From early on in the postwar period, particular locations and buildings became identified with the Holocaust, such as the notorious entrance guard house at Auschwitz-Birkenau, which appears on countless book covers as well as within films and artworks. Engaging with spatial insights and methodologies from the perspective of cultural and memory studies, scholars have attested to the production and mnemonic significance of these and less well-known sites, as well as the symbolic spatial worlds and experiences to which they give rise. These include Paul Jaskot and Gavriel Rosenfeld, who have turned respectively to Holocaust and post-Holocaust architectures as commonly overlooked sites of history and memory. Drawing attention to the construction of Holocaust space, Jaskot shows how reading architecture 'as process' rather than static structures laden with symbolic meaning reveals unique histories of forced labor in which "the goals of the SS intersected with victims' experience."5 Rosenfeld demonstrates the ways in which spaces built in response to Nazi genocide after 1945 have been variously "imbued with Jewish significance" by their users and creators, resulting in the rise to prominence of Jewish-identified architects.6 Along similar lines, Michael Meng's work has explored the ways in which Jews and gentiles interact with ruined synagogues, cemeteries and Jewish districts as important remnants of pre-war Jewish life in the post-war period in German and Polish cities.7Studies such as those noted above have tended to focus on cities and public buildings, as well as state and civic policy. But as the spatial histories and geographies of the Holocaust have helped to show, extermination often took place in rural settings (mostly located in Central and Eastern Europe), such as the killing fields where Jews were shot en masse; the forests where victims hid and were hunted by Germans and local collaborators; or the open spaces of the dissolving Reich through which former concentration camp inmates were forced to march during the final year of the war—sites in which, owing to less contained spatial dynamics, violence played out differently.8These kinds of sites, which are sparsely documented and often simply thought of...

The Cartesian method, construed as a way of organizing domains of knowledge according to the "order of reasons," was a powerful reductive tool. Descartes made significant strides in mathematics, physics, and metaphysics by relating certain complex items and problems back to more simple elements that served as starting points for his inquiries. But his reductive method also impoverished these domains in important ways, for it tended to restrict geometry to the study of straight line segments, physics to the study of (...) ambiguously constituted bits of matter in motion, and metaphysics to the study of the isolated, incorporeal knower. This book examines in detail the negative and positive impact of Descartes's method on his scientific and philosophical enterprises, exemplified by the Geometry, the Principles, the Treatise of Man, and the Meditations.

I assess various proposals for the source of the intuition that there is something problematic about contextuality, ultimately concluding that contextuality is best thought of in terms of fine-tuning. I then argue that as with other fine-tuning problems in quantum mechanics, this behaviour can be understood as a manifestation of teleological features of physics. Finally I discuss several formal mathematical frameworks that have been used to analyse contextuality and consider how their results should be interpreted by scientific realists. In the (...) course of this discussion I obtain several new mathematical results—I demonstrate that preparation contextuality is a form of fine-tuning, I show that measurement contextuality can be explained by appeal to a global constraint forbidding closed causal loops, and I demonstrate how negative probabilities can arise from a classical ontological model together with an epistemic restriction.

Madison Kilbride recently argued that insurance ) should cover in vitro fertilisation with preimplantation genetic testing services for couples at high risk of having a child affected with a genetic condition. She argues that IVF-PGT meets CMS’s definition of ‘medically necessary care’, where such care includes ‘services or supplies needed to diagnose or treat an illness, injury, condition, disease or its symptoms’. Kilbride argues that IVF-PGT satisfies this definition in two ways: as a diagnostic tool and as a treatment. Contradicting (...) Kilbride, however, I argue that IVF-PGT provides neither diagnosis nor treatment under CMS’s definition. Thus, as long as we accept CMS’s definition of medically necessary care—which Kilbride does, explicitly—it follows that IVF-PGT does not count as medically necessary care. Still, there may be other reasons to conclude that IVF-Preimplantation genetic testing should be covered, and so, it would be a mistake to reject Kilbride’s conclusion altogether. The problem is simply that Kilbride’s argument—that the procedure should be covered because it is medically necessary per CMS’s definition—is not sound. I conclude by discussing a number of other genetic services that are not currently being covered despite the fact that they do seem to satisfy CMS’s definition of ‘medically necessary diagnosis or treatment’. These services, I argue, should be provided under CMS before we consider expanding coverage to include elective procedures such as IVF-PGT. (shrink)

This book explicates Leibnizian analysis as a search for conditions of intelligibility, and reconsiders his use of principles and methods as well as his account of truth in this way. Via careful reading of well-known, lesser known, and previously unedited texts, it gives a more accurate picture of his philosophical intentions, as well as the relevance of his project to contemporary debate. Two case studies are included, one concerning logic and the other arithmetic; they illustrate a theory of intelligibility that (...) takes as its central notion "possibility for thought", a notion which allows Leibniz to escape certain traps of psychologism, the pseudo-ontology of empiricism, and the empty forms of logicism, and suggests new approaches for contemporary philosophy.

In Metaphysics Θ 1, Aristotle claims that the active power is definitionally prior to the passive power. Commentators have been puzzled by this claim, because the definitions appear, and seemingly should be, symmetric. However, their attempts to address this difficulty are dissatisfying, for commentators have not adequately appreciated what the difficulty is: they show (at most) how every kind of active power can be definitionally prior to every kind of passive power, but do not address how the active power as (...) such can be definitionally prior to the passive power as such. We undertake three tasks. First, we clarify the puzzle, demonstrating that it is the claim that the active power as such is definitionally prior to the passive power as such that stands in need of justification. Second, we defend a reading of the definitions which dissolves the appearance of symmetry. Third, we explain why the view that the active power is prior to the passive is philosophically attractive.

East Asians and Westerners differ in various aspects of perception and cognition. For example, visual memory for East Asians is believed to be more influenced by the contextual aspects of a scene than is the case for Westerners (Masuda & Nisbett, 2001). There are also differences in visual search: for Westerners, search for a long line among short is faster than for short among long, whereas this difference does not appear to hold for East Asians (Ueda et al., submitted). However, (...) it is unclear how these group-level differences originate. To investigate the extent to which they depend upon environment, we tested visual search and visual memory in East Asian immigrants who had lived in Canada for different amounts of time. Recent immigrants were found to exhibit no search asymmetry, unlike Westerners who had spent their lives in Canada. However, immigrants who had lived in Canada for more than two years showed performance comparable to that of Westerners. These differences could not be explained by the general analytic/holistic processing distinction believed to differentiate Westerners and East Asians, since all observers showed a strong holistic tendency for visual recognition. Results instead support the suggestion that exposure to a new environment can significantly affect the particular processes used to perceive a given stimulus. (shrink)

We discuss some difficulties that arise in attempting to interpret the Page–Wootters and Internal Quantum Reference Frames formalisms, then use a ‘final measurement’ approach to demonstrate that there is a workable single-world realist interpretation for these formalisms. We note that it is necessary to adopt some interpretation before we can determine if the ‘reference frames’ invoked in these approaches are operationally meaningful, and we argue that without a clear operational interpretation, such reference frames might not be suitable to define an (...) equivalence principle. We argue that the notion of superposition should take into account the way in which an instantaneous state is embedded in ongoing dynamical evolution, and this leads to a more nuanced way of thinking about the relativity of superposition in these approaches. We conclude that typically the operational content of these approaches appears only in the limit as the size of at least one reference system becomes large, and therefore these formalisms have an important role to play in showing how our macroscopic reference frames can emerge out of wholly relational facts.

Recently, some work in feminist epistemology has received more uptake from mainstream western analytic epistemology than it had in the past. There has been recognition of the importance of topics like epistemic injustice, standpoint epistemology, and epistemologies of ignorance, for instance. But these discussions are often seen as orthogonal to core epistemic theorizing - they have not received uptake as fundamental contestations of the ways we understand epistemic value, or core normative epistemic concepts. I suggest that one reasons for this (...) is the perception that insofar as feminist theorizing is responsive to moral and political concerns, it is not doing epistemology because it is not theorizing about epistemic value. This assumes a specific kind of epistemic value monism - a view whose popularity, I argue, derives at least partly from features of the methodologies that are popular in mainstream epistemology. I show that by using a different type of methodology - ameliorative inquiry - we see that there is a principled reason to doubt epistemic value monism. We can thus understand feminist theorizing in ways that are richer, more accurate, and that contribute to our understanding of the ways in which our practical, moral, and epistemic agency are intertwined.

In the Buddhist ethical traditions, equanimity along with love, compassion, and sympathetic joy form what are called the four boundless qualities, which are affective states one cultivates for moral and spiritual development. But there is a sense in which equanimity seems very unlike the three others: love, compassion, and sympathetic joy all imply an emotional investment in others, whereas equanimity seems to imply an absence of such investment. This observation has provoked debate as to how to properly understand the relationship (...) between equanimity and the other three qualities. In this paper, I propose that equanimity - like love, compassion, and sympathetic joy - is itself a virtue of good intimate relationships and not in conflict with such virtues. (shrink)

This book deals with a topic that has been largely neglected by philosophers of science to date: the ability to refer and analyze in tandem. On the basis of a set of philosophical case studies involving both problems in number theory and issues concerning time and cosmology from the era of Galileo, Newton and Leibniz up through the present day, the author argues that scientific knowledge is a combination of accurate reference and analytical interpretation. In order to think well, we (...) must be able to refer successfully, so that we can show publicly and clearly what we are talking about. And we must be able to analyze well, that is, to discover productive and explanatory conditions of intelligibility for the things we are thinking about. The book’s central claim is that the kinds of representations that make successful reference possible and those that make successful analysis possible are not the same, so that significant scientific and mathematical work typically proceeds by means of a heterogeneous discourse that juxtaposes and often superimposes a variety of kinds of representation, including formal and natural languages as well as more iconic modes. It demonstrates the virtues and necessity of heterogeneity in historically central reasoning, thus filling an important gap in the literature and fostering a new, timely discussion on the epistemology of science and mathematics.

Empirical psychology documents widespread evidence of bias in the ways that people select, interpret, and selectively interpret evidence in forming and revising their beliefs. These biases can function to create and perpetuate epistemologies of ignorance. I argue that virtue epistemology can help us explain what goes epistemically wrong in these cases, and can offer positive advice, orienting us toward ways to right it. In particular, I defend the virtue approach from epistemic situationist worries about the empirical plausibility of individual agents' (...) ability to develop corrective virtues. I argue that situational virtues are genuine responsibilist virtues, and are one of the tools at our disposal for overcoming epistemologies of ignorance. (shrink)

Opponents of same-sex marriage suggest that legalizing same-sex marriage will start a slide down a “slippery-slope” leading to the legalization of all kinds of salacious family arrangements including polygamy. In this paper, I argue that because previous attempts by liberal political theorists to combat such slippery-slope arguments have been unsuccessful, there are two options left open to political liberals. Either one could embrace polygamy as a logically consistent implication of extending civil liberties to same-sex couples or one could find a (...) new strategy for blocking the slide down the slope. I take the second option arguing that we ought to devise a harm principle for domestic partnerships. Once this principle has been established, it becomes clear that the risk of exploitation for those potentially occupying the multiple side of the marriage is sufficient reason to reject polygamous marriage arrangements. I conclude that, contrary to appearances, holding both same-sex marriage is permissible and polygamous marriage is impermissible is at the same time consistent and consistently liberal. (shrink)

This qualitative study of 27 women animal activists examines the risks and rewards that accompany a commitment to animal rights activism. One of the common beliefs about animal rights activists is that their political choices are fanatic and unyielding, resulting in rigid self-denial. Contrary to this notion, the women in this study experienced both the pain and the joy of their transformation toward animal activism. Activism took an enormous toll on their personal relationships, careers, and emotional well being. They struggled (...) as friendships ended and family relationships suffered; some experienced harassment and abuse as a result of their efforts. Yet the women were just as likely to extol the rewards and pleasure gained from their participation in the cause of animal liberation. These included a heightened awareness of political issues, greater self-confidence, the feeling that they were making a difference in the world, and the joy of living a “more meaningful life.”.

This article replies to the insightful contributions to the book symposium for On Taking Offence, These range from theoretical questions about how we should conceptualise an emotion like offence and the role of empirical evidence when justifying it, to practical questions about who has the power to take offence effectively and how to dispute another's offence-taking. In this reply, I first defend offence as a distinct emotion. Second, I argue against the implicit conception of social standing that underpins some of (...) these challenges, as static and fixed rather than dynamic, emerging from the particularities of particular social interactions, and easily threatened. Third, I address the instrumental justification of offence. I conclude with some unanswered questions, and some reasons to remain optimistic about what taking offence can do. (shrink)

The ‘new realist’ G E Moore is hardly known as a metaphysician of time, yet I argue his 1910–11 lectures, later published as Some Main Problems of Philosophy, offer the first substantial English-language defence of presentism and the A-theory. This paper contextualises Moore’s positions, stressing his intellectual connections with J M E McTaggart and Bertrand Russell; explores his Common Sense metaphysics of time; and argues that his time realism owes a great debt to ‘old realist’ Henry Sidgwick.

The omen of the door and the eagle at Iliad 24.314–21 appears to have sparked scant scholarly interest, but deserves careful attention. The omen itself forms part of an analogy, for the eagle is likened in the size of its wingspan to a large, barred door. This simile might seem unremarkable, merely a convenient means of depicting great size, a casual juxtaposition of two ordinary nouns. The omen, on the whole, might be dismissed as nothing more than a conventional expression (...) of divine favor. But closer scrutiny will reveal that there is, in fact, nothing arbitrary or haphazard in the selection of the terms of the analogy. Appreciation of the elegance and subtlety of the simile in turn reveals the full import of the omen. (shrink)

This chapter places Alexander in his intellectual context, focusing on his early 1880s work, and exploring how that flows into his mature work. It considers Alexander’s views on two major late nineteenth century debates about the mind. First, what is the relationship of mind to nature? During this period, idealists were battling with realists over whether mind should be identified with nature. I argue Alexander was always a realist, and speculate on his association with Oxford realism. Second, how did our (...) minds evolve biologically? Some theorists argued for naturalism, whilst others argued for supernaturalism. I argue Alexander was always a naturalist. Despite Alexander’s realism and naturalism, he leans towards both idealism and supernaturalism, sharply distinguishing his realism from that of early analytic philosophers. The final part of the chapter explains that while Alexander’s system won few converts, it was widely admired and remains a grand edifice in the history of speculative metaphysics. (shrink)
