Consider a recent expression of such traditionalism.

When Sandra Harding called for an epistemology of science whose systematic attention to the gendered Status of epistemic agents renders it ‘less partial and distorted’ than ‘traditional’ epistemologies, some commentators recoiled in horror. Propelled by ‘a mad form of the genetic fallacy’ they said, she descends ‘the slide to an arational account of science.’ On a less melodramatic reading, feminist epistemologies such as Harding's advocate not irrationalism, but senses of rationality more expanded than those which they associate with ‘traditional’ epistemology.

We discuss the intertwined topics of Fulling non-uniqueness and the Unruh effect. The Fulling quantization, which is in some sense the natural one for an observer uniformly accelerated through Minkowski spacetime to adopt, is often heralded as a quantization of the Klein-Gordon field which is both physically relevant and unitarily inequivalent to the standard Minkowski quantization. We argue that the Fulling and Minkowski quantizations do not constitute a satisfactory example of physically relevant, unitarily inequivalent quantizations, and indicate what it would (...) take to settle the open question of whether a satisfactory example exists. A popular gloss on the Unruh effect has it that an observer uniformly accelerated through the Minkowski vacuum experiences a thermal flux of Rindler quanta. Taking the Unruh effect, so glossed, to establish that the notion of particle must be relativized to a reference frame, some would use it to demote the particle concept from fundamental status. We explain why technical results do not support the popular gloss and why the attempted demotion of the particle concept is both unsuccessful and unnecessary. Fulling non-uniqueness and the Unruh effect merit attention despite these negative verdicts because they provide excellent vehicles for illustrating key concepts of quantum field theory and for probing foundational issues of considerable philosophical interest.

Philosophers of quantum mechanics have generally addressed exceedingly simple systems. Laura Ruetsche offers a much-needed study of the interpretation of more complicated systems, and an underexplored family of physical theories, such as quantum field theory and quantum statistical mechanics, showing why they repay philosophical attention. She guides those familiar with the philosophy of ordinary QM into the philosophy of 'QM infinity', by presenting accessible introductions to relevant technical notions and the foundational questions they frame--and then develops and defends (...) answers to some of those questions. Finally, Ruetsche highlights ties between the foundational investigation of QM infinity and philosophy more broadly construed, in particular by using the interpretive problems discussed to motivate new ways to think about the nature of physical possibility and the problem of scientific realism.

I explore how gender can shape the pragmatics of speech. In some circumstances, when a woman deploys standard discursive conventions in order to produce a speech act with a specific performative force, her utterance can turn out, in virtue of its uptake, to have a quite different force—a less empowering force—than it would have if performed by a man. When members of a disadvantaged group face a systematic inability to produce a specific kind of speech act that they are entitled (...) to perform—and in particular when their attempts result in their actually producing a different kind of speech act that further compromises their social position and agency—then they are victims of what I call discursive injustice. I examine three examples of discursive injustice. I contrast my account with Langton and Hornsby's account of illocutionary silencing. I argue that lack of complete control over the performative force of our speech acts is universal, and not a special marker of social disadvantage. However, women and other relatively disempowered speakers are sometimes subject to a distinctive distortion of the path from speaking to uptake, which undercuts their social agency in ways that track and enhance existing social disadvantages.

This paper discusses a crisis of accountability that arises when scientific collaborations are massively epistemically distributed. We argue that social models of epistemic collaboration, which are social analogs to what Patrick Suppes called a “model of the experiment,” must play a role in creating accountability in these contexts. We also argue that these social models must accommodate the fact that the various agents in a collaborative project often have ineliminable, messy, and conflicting interests and values; any story about accountability in (...) a massively distributed collaboration must therefore involve models of such interests and values and their methodological and epistemic effects.

One realist response to the pessimistic meta-induction distinguishes idle theoretical wheels from aspects of successful theories we can expect to persist and espouses realism about the latter. Implementing the response requires a strategy for identifying the distinguished aspects. The strategy I will call renormalization group realism has the virtue of directly engaging the gears of our best current physics—perturbative quantum field theories. I argue that the strategy, rather than disarming the skeptical possibilities evinced by the pessimistic meta-induction, forces them to (...) retreat a level. I also suggest that those skeptical possibilities continue to carry force. (shrink)

The availability of unitarily inequivalent representations of the canonical commutation relations constituting a quantization of a classical field theory raises questions about how to formulate and pursue quantum field theory. In a minimally technical way, I explain how these questions arise and how advocates of the Hilbert space and of the algebraic approaches to quantum theory might answer them. Where these answers differ, I sketch considerations for and against each approach, as well as considerations which might temper their apparent rivalry.

Taking Arthur Fine’s The Shaky Game as my inspiration, and the recent 25th anniversary of the publication of that work as the occasion to exercise that inspiration, I sketch an alternative to the “Naturalism” prevalent among philosophers of physics. Naturalism is a methodology eventuating in a metaphysics. The methodology is to seek the deep framework assumptions that make the best sense of science; the metaphysics is furnished by those assumptions and supported by their own support of science. The alternative presented (...) here, which I call “Locavoracity,” shares Naturalism’s commitment to making sense of science, but alters Naturalism’s methodology. The Locavore’s sense-making projects are piecemeal, rather than sweeping. The Locavore’s hypothesis is that the collection of local sense-making projects fails to issue a single overarching unifying framework deserving of the title “the metaphysics that makes the best sense of science.” I muster some examples supporting the Locavore hypothesis from the interpretation of quantum field theories. (shrink)

If a classical system has infinitely many degrees of freedom, its Hamiltonian quantization need not be unique up to unitary equivalence. I sketch different approaches (Hilbert space and algebraic) to understanding the content of quantum theories in light of this non‐uniqueness, and suggest that neither approach suffices to support explanatory aspirations encountered in the thermodynamic limit of quantum statistical mechanics.

I explore how we negotiate sexual encounters with one another in language and consider the pragmatic structure of such negotiations. I defend three theses: Discussions of consent have dominated the philosophical and legal discourse around sexual negotiation, and this has distorted our understanding of sexual agency and ethics. Of central importance to good-quality sexual negotiation are sexual invitations and gift offers, as well as speech designed to set up safe frameworks and exit conditions. Sexual communication that goes well does not (...) just prevent harm; it enables forms of agency, pleasure, and fulfillment that would not otherwise be possible. (shrink)

Philosophical accounts of quantum theory commonly suppose that the observables of a quantum system form a Type-I factor von Neumann algebra. Such algebras always have atoms, which are minimal projection operators in the case of quantum mechanics. However, relativistic quantum field theory and the thermodynamic limit of quantum statistical mechanics make extensive use of von Neumann algebras of more general types. This chapter addresses the question whether interpretations of quantum probability devised in the usual manner continue to apply in the (...) more general setting. Features of non-type I factor von Neumann algebras are cataloged. It is shown that these novel features do not cause the familiar formalism of quantum probability to falter, since Gleason's Theorem and the Lüders Rule can be generalized. However, the features render the problem of the interpretation of quantum probability more intricate. (shrink)

Some feminist epistemologists make the radical claim that there are varieties of epistemically valid warrant that agents access only through having lived particular types of contingent history, varieties of epistemic warrant to which, moreover, the confirmation-theoretic accounts of warrant favored by some traditional epistemologists are inapplicable. I offer Aristotelian virtue as a model for warrant of this sort, and use loosely Aristotelian vocabulary to express, and begin to evaluate, a range of feminist epistemological positions.

A normal state on a von Neumann algebra defines a countably additive probability measure over its projection lattice. The von Neumann algebras familiar from ordinary QM are algebras of all the bounded operators on a Hilbert space H, aka Type I factor von Neumann algebras. Their normal states are density operator states, and can be pure or mixed. In QFT and the thermodynamic limit of QSM, von Neumann algebras of more exotic types abound. Type III von Neumann algebras, for instance, (...) have no pure normal states; the pure states they do have fail to be countably additive. I will catalog a number of temptations to accord physical significance to non-normal states, and then give some reasons to resist these temptations: pure though they may be, non-normal states on non-Type I factor von Neumann algebras can't do the interpretive work we've come to expect from pure states on Type I factors; our best accounts of state preparation don't work for the preparation of non-normal states; there is a sense in which non-normal states fail to instantiate the laws of quantum mechanics.

The goal of this paper is to give an account of the pragmatic and social function of slurs, taken as speech acts. I develop a theory of the distinctive illocutionary force and pragmatic structure of slurs. I argue that slurs help to produce subjects who occupy social identities carved out by pernicious ideologies, and that they do this whether or not anyone involved intends for the slur to work that way or has any particular feelings or conscious thoughts associated with (...) using or being targeted by the slur. I offer an Althusser‐inspired account of what an ideology is, as well as of the mechanisms by which slurs can serve to cue and strengthen ideologies. A slur, I argue, is a kind of interpellation, which reduces its target to a generic identity and derogates and subordinates its target. I explore how slurs and ideologies work in tandem to constitute and fortify one another. I end by applying my account to see how well it fits and helps illuminate three quite different, especially complex slurs. (shrink)

I explore the role that values and interests, especially ideological interests, play in managing and balancing epistemic risks in medicine. I will focus in particular on how diseases are identified and operationalized. Before we can do biomedical research on a condition, it needs to be identified as a medical condition, and it needs to be operationalized in a way that lets us identify sufferers, measure progress, and so forth. I will argue that each time we do this, we engage in (...) epistemic risk balancing that inevitably draws upon values and interests, often including social and ideological values. My main interest here is in the conceptualization of infertility as a disease. Infertility is a rich test case for exploring the interplay between interests and epistemic risk management. There is no uncontested or standardized definition of infertility. The various definitions of it are internally ambiguous and tension-ridden, and in spectacular contradiction with one another. Many interest groups who are invested in framing infertility as a pressing problem deserving of social and medical redress are quick to insist that it is a legitimate ‘disease,’ but they cannot agree on which disease it is, what its symptoms or diagnostic markers are, or even what its basic ontology is. I suggest that there are political explanations for this epistemic mess. Indeed, I contend that there are good scientific and ethical reasons to reduce away the category of ‘infertility,’ especially understood as a scientific or medical category; I argue that we should excise the concept from our research and clinical practices.

Stephen Hawking has argued that universes containing evaporating black holes can evolve from pure initial states to mixed final ones. Such evolution is non-unitary and so contravenes fundamental quantum principles on which Hawking's analysis was based. It disables the retrodiction of the universe's initial state from its final one, and portends the time-asymmetry of quantum gravity. Small wonder that Hawking's paradox has met with considerable resistance. Here we use a simple result for C*-algebras to offer an argument for pure-to-mixed state (...) evolution in black hole evaporation, and review responses to the Hawking paradox with respect to how effectively they rebut this argument.

Mass Hysteria examines the medical and cultural practices surrounding pregnancy, new motherhood, and infant feeding. Late eighteenth century transformations in these practices reshaped mothers' bodies, and contemporary norms and routines of prenatal care and early motherhood have inherited the legacy of that era. As a result, mothers are socially positioned in ways that can make it difficult for them to establish and maintain healthy and safe boundaries and appropriate divisions between public and private space.

Wilfrid Sellars's iconic exposé of the ‘myth of the given’ taught us that experience must present the world to us as normatively laden, in the sense that the contents of experience must license inferences, rule out and justify various beliefs, and rationalize actions. Somehow our beliefs must be governed by the objects as they present themselves to us. Often this requirement is cashed out using language that attributes agent-like properties to objects: we are described as ‘accountable to’ objects, while objects (...) ‘hold us’ to standards, and so forth. But such language is either deeply anti-naturalistic or trades on a set of metaphors in need of a literal translation. We offer an explanation of how the material features of the world, as received in experience, can rationally constrain our beliefs and practices—one that makes no recourse to this imagery. In particular, we examine the structure of ostensive practices (that is, practices of directing one another's attention to objects and features of the world) and the distinctive role they play in making us jointly beholden to how things actually are.

Van Fraassen's 1991 modal interpretation of Quantum Mechanics offers accounts of measurement and state preparation. I argue that both accounts overlook a class of interactions I call General Unitary Measurements, or GUMs. Ironically, GUMs are significant for van Fraassen's account of measurement because they challenge it, and significant for his account of preparation because they simplify it. Van Fraassen's oversight prompts a question about modal interpretations: developed to account for ideal measurement outcomes, can they consistently account as well for the (...) whole horizon of laboratory practices by which we investigate QM?

An “intrinsically mixed” state is a mixed state of a system that is ‘orthogonal’ to every pure state of that system. Although the presence of such states in the quantum theories of infinite systems is well known to those who work with such theories, intrinsically mixed states are virtually unheralded in the philosophical literature. Rob Clifton was thoroughly familiar with intrinsically mixed states. I aim here to introduce them to a wider audience—and to encourage that audience to cultivate their acquaintance (...) by suggesting that intrinsically mixed states undermine assumptions framing standard discussions of the quantum measurement problem.

Mothers serve as an important layer of the health-care system, with special responsi-bilities to care for the health of families and nations. In our social discourse, we tend to treat maternal “choices” as though they were morally and causally Self-contained units of influence with primary control over children's health. In this essay, I use infant feeding as a lens for examining the ethical contours of mothers’ caretaking practices and responsibilities, as they are situated within cultural meanings and institutional pressures. I (...) give a close critical reading of the content and strategy of the new breastfeeding advocacy campaign sponsored by the United States Department of Health and Human Services. I argue that the campaign is unlikely to substantially increase breastfeeding rates, unresponsive and even hostile to many women's actual concerns about breastfeeding, and well positioned to produce shame and compromise agency among the women it targets.

Ghostwriting scandals are pervasive in industry-funded biomedical research, and most responses to them have presumed that they represent a sharp transgression of the norms of scientific authorship. I argue that in fact, ghostwriting represents a continuous extension of current socially accepted authorship practices. I claim that the radically collaborative, decentralized, interdisciplinary research that forms the gold standard in medicine is in an important sense unauthored, and that this poses a serious problem in applied social epistemology. It is no easy matter (...) to find procedural or architectural solutions that can secure epistemic trust and accountability for collaborative publishing in biomedicine. (shrink)

Epistemologists generally think that genuine warrant that is available to anyone must be available to everyone who is exposed to the relevant causal inputs and is able and willing to properly exercise her rationality. The motivating idea behind this requirement is roughly that an objective view is one that is not bound to a particular perspective. In this paper I ask whether the aperspectivality of our warrants is a precondition for securing the objectivity of our claims. I draw upon a (...) Sellarsian account of perception in order to argue that it is not; rather, inquirers can have contingent properties and perspectives that give them access to forms of rational warrant and objective knowledge that others do not have. The universal accessibility of reasons, on my account, is not a precondition for the legitimacy of any actual warrant, but rather a regulative ideal governing inquiry and communication. (shrink)

A number of arguments have been given to show that the modal interpretation of ordinary nonrelativistic quantum mechanics cannot be consistently extended to the relativistic setting. We find these arguments inconclusive. However, there is a prima facie reason to think that a tension exists between the modal interpretation and relativistic invariance; namely, the best candidate for a modal interpretation adapted to relativistic quantum field theory, a prescription due to Rob Clifton, comes out trivial when applied to a number of systems (...) of physical interest. However, it is far from clear whether this difficulty for the modal interpretation is traceable to relativistic invariance per se or to the infinite number of degrees of freedom involved. In any case, the proponents of the modal interpretation have work to do. (shrink)

According to a regnant criterion of physical equivalence for quantum theories, a quantum field theory (QFT) typically admits continuously many physically inequivalent realizations. This, the second of a two-part introduction to topics in the philosophy of QFT, continues the investigation of this alarming circumstance. It begins with a brief catalog of quantum field theoretic examples of this non-uniqueness, then presents the basics of the algebraic approach to quantum theories, which discloses a structure common even to ‘physically inequivalent’ realizations of a (...) QFT. Finally, it introduces and evaluates a handful of strategies for interpreting quantum theories in the face of the non-uniqueness of their Hilbert space representations. (shrink)

This is the first of a two-part introduction to some interpretive questions that arise in connection with quantum field theories (QFTs). Some of these questions are continuous with those familiar from the discussion of ordinary non-relativistic quantum mechanics (QM). For example, questions about locality can be rigorously posed and fruitfully pursued within the framework of QFT. A stark disanalogy between QFTs and ordinary QM – the former, but not the latter, typically admit infinitely many putatively physically inequivalent realizations – prompts (...) relatively novel questions, questions about how to understand and adjudicate different strategies for equipping quantum theories with content. Part I sketches the fate of locality and related notions in QFT, then documents the non-uniqueness unprecedented in ordinary QM but rampant in QFT. Part II presents foundations issues raised by non-uniqueness. (shrink)

We explain why technical results do not support the popular gloss and why the attempted demotion of the particle concept is both unsuccessful and unnecessary. Fulling non‐uniqueness and the Unruh effect merit attention despite these negative verdicts because they provide excellent vehicles for illustrating key concepts of quantum field theory and for probing foundational issues of considerable philosophical interest.

Philosophers have often posited a foundational calling voice, such that hearing its call constitutes subjects as responsive and responsible negotiators of normative claims. I give the name ldquo;transcendental conscience to that which speaks in this founding, constitutive voice. The role of transcendental conscience is not – or not merely – to normatively bind the subject, but to constitute the possibility of the subject's being bound by any particular, contentful normative claims in the first place. I explore the ontological and temporal (...) status of transcendental conscience, using Heidegger's account of conscience in Being and Time as my textual touchstone. I ask what performative structure the call of conscience might have that would enable it to constitute normative responsiveness, and I raise some temporal conundrums surrounding this structure. I argue that it is incoherent to attempt to give a literal, chronological account of the origin of normative grip and response. I suggest that we can best understand the founding calls of conscience, not as literal events occurring in regular time, but as events that can only show up retrospectively, as occurring in an ever-receding, unlocalizable past, and that these calls can only be figured mythically and metaphorically. Appropriating a Derridean term, I claim that the voice of transcendental conscience must be that of a lsquo;ghost, whose call binds us by haunting us – a haunting that is no less transcendentally necessary for its inability to be translated into a literal historical event.

There are challenges to the dominant research paradigm in breast cancer science. In the United States, science and social activism create paradigmatic shifts. Using interviews, ethnographic observations, and an extensive review of the literature, we create a three-dimensional model to situate changes in scientific controversy concerning environmental causes of breast cancer. We identify three paradigm challenges posed by activists and some scientists: to move debates about causation upstream to address causes; to shift emphasis from individual to modifiable societal-level factors beyond (...) an individual’s control; and to allow direct lay involvement in research, which may raise new questions and change how questions are approached, the methods used, and the standards of proof. We use our model to examine controversies about doing scientific research, interpreting scientific results, and acting on science. Ultimately, we aim to understand what impedes construction of new methodologies and knowledge about environmental factors in human disease. (shrink)

As a culture, we have a tendency to measure motherhood in terms of a set of signal moments that have become the focus of special social attention and anxiety; we interpret these as emblematic summations of women's mothering abilities. Women's performances during these moments can seem to exhaust the story of mothering, and mothers often internalize these measures and evaluate their own mothering in terms of them. "Good" mothers are those who pass a series of tests—they bond properly during their (...) routine ultrasound screening, they do not let a sip of alcohol cross their lips during pregnancy, they give birth vaginally without pain medication, they do not offer their child an artificial nipple during the first six months, they feed their children maximally nutritious meals with every bite, and so on. This reductive understanding of mothering has had counterproductive effects upon health care practice and policy, encouraging measures that penalize mothers who do not live up to cultural norms during signal moments, while failing to promote extended narratives of healthy mothering.

This volume explores the relationship between Kant's aesthetic theory and his critical epistemology as articulated in the Critique of Pure Reason and the Critique of the Power of Judgment. The essays, written specially for this volume, explore core elements of Kant's epistemology, such as his notions of discursive understanding, experience, and objective judgment. They also demonstrate a rich grasp of Kant's critical epistemology that enables a deeper understanding of his aesthetics. Collectively, the essays reveal that Kant's critical project, and the (...) dialectics of aesthetics and cognition within it, is still relevant to contemporary debates in epistemology, philosophy of mind, and the nature of experience and objectivity. The book also yields important lessons about the ineliminable, yet problematic place of imagination, sensibility and aesthetic experience in perception and cognition. (shrink)

It has been suggested that the Modal Interpretation of Quantum Mechanics (QM) is "incomplete" if it lacks a dynamics for possessed values. I argue that this is only one of two possible attitudes one might adopt toward a Modal Interpretation without dynamics. According to the other attitude, such an interpretation is a complete interpretation of QM as standardly formulated, an interpretation whose innovation is to attempt to make sense of the quantum realm without the expedient of novel physics. Then I (...) explain why this attitude, though available, is unattractive. Without dynamics, the Modal Interpretation vanquishes the measurement problem only, it seems, to succumb to the problem of state preparation. On this view, the Modal Interpretation needs dynamics not to be an interpretation at all, but to be an adequate one. I review reasons to suspect that the dynamics which would best suit the Modal Interpretation--a dynamics equivalent to a set of two time transition probabilities of the sort used to solve the preparation problem--is not a dynamics the interpretation can have. I close with a brief discussion of versions of the Modal Interpretation that may not succumb to the considerations presented here. (shrink)

In Games: Agency as Art, Thi Nguyen has given us a deep and compelling picture of agency as much more layered, volatile, environment-dependent and discontinuous than it appears in most philosophical accounts. Games ‘inscribe … forms of agency into artifactual vessels’.1 1 When we play a game, we take up a form of agency, including a set of motivations, values and goals, which has been artificially provided by the game. Our purpose in playing, in the kinds of gameplay that interest (...) Nguyen, is to have the aesthetic experience of first-personally exercising the kind of agency sculpted by the game. As we move in and out of gameplay, we take up and drop values, motives, and goals that are provided to us by the game. Games can expand our autonomy and the richness of life by allowing us to practice different forms of agency, taking on different ends for the aesthetic experience of striving to meet them. While I am on board with these central moves of Nguyen’s book, in this essay I will argue that the situation is substantially messier than Nguyen portrays it as being. Game play, I will claim, is inextricably embedded and entangled in its larger social, material and cultural context. Conversely, I will argue, everyday life is routinely sculpted in ways Nguyen claims are distinctive of games. (shrink)

The standard bioethics account is that respecting patient autonomy means ensuring that patients make their own decisions, and that requires that they give informed consent. In fact, respecting autonomy often has more to do with the overall shape and meaning of their health care regimes. Ideally, patients will sometimes take control of their health care but sometimes defer to medical authority. The physician's task is, in part, to inculcate patients into the appropriate good health care regimes.

The simplest case of quantum field theory on curved spacetime—that of the Klein–Gordon field on a globally hyperbolic spacetime—reveals a dilemma: In generic circumstances, either there is no dynamics for this quantum field, or else there is a dynamics that is not unitarily implementable. We do not try to resolve the dilemma here, but endeavour to spell out the consequences of seizing one or the other horn of the dilemma.

Over the last several years, as cesarean deliveries have grown increasingly common, there has been a great deal of public and professional interest in the phenomenon of women 'choosing' to deliver by cesarean section in the absence of any specific medical indication. The issue has sparked intense conversation, as it raises questions about the nature of autonomy in birth. Whereas mainstream bioethical discourse is used to associating autonomy with having a large array of choices, this conception of autonomy does not (...) seem adequate to capture concerns and intuitions that have a strong grip outside this discourse. An empirical and conceptual exploration of how delivery decisions ought to be negotiated must be guided by a rich understanding of women's agency and its placement within a complicated set of cultural meanings and pressures surrounding birth. It is too early to be 'for' or 'against' women's access to cesarean delivery in the absence of traditional medical indications – and indeed, a simple pro- or con- position is never going to do justice to the subtlety of the issue. The right question is not whether women ought to be allowed to choose their delivery approach but, rather, taking the value of women's autonomy in decision-making around birth as a given, what sorts of guidelines, practices, and social conditions will best promote and protect women's full inclusion in a safe and positive birth process.
