Debates about the ethics and effects of placebos and whether ‘placebos’ in clinical trials of complex treatments such as acupuncture are adequate rage. Yet there is currently no widely accepted definition of the ‘placebo’. A definition of the placebo is likely to inform these controversies. Grünbaum’s characterization of placebos and placebo effects has been touted by some authors as the best attempt thus far, but has not won widespread acceptance largely because Grünbaum failed to specify what he means by a (...) therapeutic theory and because he does not stipulate a special role for expectation effects. Grünbaum claims that placebos are treatments whose ‘characteristic features’ do not have therapeutic effects on the target disorder. I show that with four modifications, Grünbaum’s definition provides a defensible account of placebos for the purpose of constructing placebo controls within clinical trials. The modifications I introduce are: adding a special role for expectations, insisting that placebo controls control for all and only the effects of the incidental treatment features, relativizing the definition of placebos to patients, and introducing harmful interventions and nocebos to the definitional scheme. I also provide guidance for classifying treatment features as characteristic or incidental. (shrink)

We discuss from a philosophical perspective the way in which the normal concept of time might be said to `emerge' in a quantum theory of gravity. After an introduction, we briefly discuss the notion of emergence, without regard to time. We then introduce the search for a quantum theory of gravity ; and review some general interpretative issues about space, time and matter. We then discuss the emergence of time in simple quantum geometrodynamics, and in the Euclidean approach. Section 6 (...) concludes. (shrink)

In a series of recent papers, Timothy Williamson has argued for the surprising conclusion that there are cases in which you know a proposition in spite of its being overwhelmingly improbable given what you know that you know it. His argument relies on certain formal models of our imprecise knowledge of the values of perceptible and measurable magnitudes. This paper suggests an alternative class of models that do not predict this sort of improbable knowing. I show that such models are (...) motivated by independently plausible principles in the epistemology of perception, the epistemology of estimation, and concerning the connection between knowledge and justified belief.

In this paper we present a schema for describing dualities between physical theories, and illustrate it in detail with the example of bosonization: a boson-fermion duality in two-dimensional quantum field theory. The schema develops proposals in De Haro : these proposals include construals of notions related to duality, like representation, model, symmetry and interpretation. The aim of the schema is to give a more precise criterion for duality than has so far been considered. The bosonization example, or boson-fermion duality, has (...) the feature of being simple, yet rich enough, to illustrate the most relevant aspects of our schema, which also apply to more sophisticated dualities. The richness of the example consists, mainly, in its concern with two non-trivial quantum field theories: including massive Thirring-sine-Gordon duality, and non-abelian bosonization. This prompts two comparisons with the recent philosophical literature on dualities:--- Unlike the standard cases of duality in quantum field theory and string theory, where only specific simplifying limits of the theories are explicitly known, the boson-fermion duality is known to hold {\it exactly}. This exactness can be exhibited explicitly. The bosonization example illustrates both the cases of isomorphic and {\it non-isomorphic} models: which we believe the literature on dualities has not so far discussed. (shrink)

Regulating affective responses to acute stress has the potential to improve health, performance, and well-being outcomes. Using the biopsychosocial model of challenge and threat as an organizing framework, we review how appraisals inform affective responses and highlight research that demonstrates how appraisals can be used as regulatory tools. Arousal reappraisal, specifically, instructs individuals on the adaptive benefits of stress arousal so that arousal is conceptualized as a coping resource. By reframing the meaning of signs of arousal that accompany stress, it (...) is possible to break the link between stressful situations, and malignant physiological responses and experiences of negative affect. Applications of arousal reappraisal for academic contexts and clinical science, and directions for future research are discussed. (shrink)

Hypnosis is considered a unique tool capable of modulating cognitive processes. The extent to which hypnotic suggestions intervenes is still under debate. This study was designed to provide a new insight into this issue, by focusing on an unintentional emotional process: attentional bias. In Experiment 1, highly suggestible participants performed three sessions of an emotional Stroop task where hypnotic suggestions aiming to increase and decrease emotional reactivity towards emotional stimuli were administered within an intra-individual design. Compared to a baseline condition (...) (without hypnotic suggestion), a significant increase in attentional bias was found when a hypnotic suggestion to increase emotional reactivity was administered. In contrast, the bias was eliminated when a suggestion to decrease emotional reactivity was administered. Experiment 2 investigated the effect of session repetition on attentional bias across three successive experimental sessions without hypnosis, and showed that the emotional Stroop effect did not vary across sessions. Hence, session repetition could not account for part of the modulation of attentional bias in Experiment 1. Taken together, the results suggest that specific hypnotic suggestions can influence elicitation of unintentional emotional processing. The implications are discussed regarding the locus of intervention of hypnotic suggestion in cognitive and emotional processes. (shrink)

The COVID-19 pandemic has brought the long-standing public health practice of contact tracing into the public spotlight. While contact tracing and case investigation have been carefully designed to protect privacy, the huge volume of tracing which is being carried out as part of the pandemic response in the United States is highlighting potential concerns around privacy, legality, and equity. Contact tracing during the pandemic has gained particular attention for the new use of digital technologies—both on the consumer side in the (...) form of Exposure Notification applications, and for public health agencies as digital case management software systems enable massive scaling of operations. While the consumer application side of digital innovation has dominated the news and academic discourse around privacy, people are likely to interact more intensively with public health agencies and their use of digital case management systems. Effective use of digital case management for contact tracing requires revisiting the existing legal frameworks, privacy protections, and security practices for management of sensitive health data. The scale of these tools and demands of an unprecedented pandemic response are introducing new risks through the collection of huge volumes of data, and expanding requirements for more adept data sharing among jurisdictions. Public health agencies must strengthen their best practices for data collection and protection even in the absence of comprehensive or clear guidance. This requires navigating a difficult balance between rigorous data protection and remaining highly adaptive and agile. (shrink)

The biopsychosocial model of challenge and threat posits that resource and demand appraisals interact in situations of acute stress to determine affective responses, and concomitant physiological responses, motivation, and decisions/behaviors. Regulatory approaches that alter appraisals to regulate challenge and threat affective states have the potential to facilitate coping. This reply clarifies the conceptualization of one such regulatory approach, arousal reappraisal, and suggests avenues for future research. However, it is important to note that arousal reappraisal is not a “silver bullet” for (...) improving stress outcomes, nor should this strategy be expected to positively impact all individuals. More work is needed to better elucidate how psychological and biological stress processes interact to shape health. (shrink)

“Terrorism”' is sometimes defined as a “form ofcoercion.” But there are important differences between ordinary coercion and terrorist intimidation. This paper explores some of those differences, particularly the relation between coercion, on the one hand, and terror and terrorization, on the other hand. The paper argues that while terrorism is not necessarily associated with terror in the literal sense, it does often seek to instill a mental state like terror in the populations that it targets. However, the point of instilling (...) this mental state is not necessarily coercive or intimidatory: one can try to instill terror as an act of punishment, or as an expressive or therapeutic act, or because one values the political consequences that might follow, or because one thinks terror is preferable, from an ethical point of view, to the inauthentic complacency that characterizes the targeted population at present. Though this paper asks questions about the definition of “terrorism,” these questions are not asked for their own sake. The quest for a canonical definition of “terrorism” is probably a waste of time. But asking questions which sound like questions of definition is sometimes a fruitful way of focusing our reflections on terrorism and organizing our response. (shrink)

We use the normality framework of Goodman and Salow (2018, 2021, 2023b) to investigate of dynamics of rational belief. The guiding idea is that people are entitled to believe that their circumstances aren’t especially abnormal. More precisely, a rational agent’s beliefs rule out all and only those possibilities that are either (i) ruled out by their evidence or (ii) sufficiently less normal than some other possibility not ruled out by their evidence. Working within this framework, we argue that the logic (...) of rational belief revision is much weaker than is usually supposed. We do so by isolating a natural family of orthodox principles about belief revision, describing realistic cases in which these principles seem to fail, and showing how these counterexamples are predicted by independently motivated models of the cases in question. In these models, whether one evidential possibility counts as sufficiently less normal than another is determined by underlying probabilities (together with a contextually determined question). We argue that the resulting probabilistic account of belief compares favorably with other such accounts, including Lockeanism (Foley, 1993), a ‘stability’ account inspired by Leitgeb (2017), the ‘tracking theory’ of Lin and Kelly (2012), and the influential precursor of Levi (1967). We show that all of these accounts yield subtly different but similarly heterodox logics of belief revision. (shrink)

In Section 2, I survey some of the ways that computers are used in mathematics. These raise questions that seem to have a generally epistemological character, although they do not fall squarely under a traditional philosophical purview. The goal of this article is to try to articulate some of these questions more clearly, and assess the philosophical methods that may be brought to bear. In Section 3, I note that most of the issues can be classified under two headings: some (...) deal with the ability of computers to deliver appropriate “evidence” for mathematical assertions, a notion that is explored in Section 4, while others deal with the ability of computers to deliver appropriate mathematical “understanding,” a notion that is considered in Section 5. Final thoughts are provided in Section 6. (shrink)

Depending on our mode of reasoning—moral, prudential, instrumental, empirical, dialectical, and so on—we may come to vastly different conclusions on the nature of death and the appropriate orientation toward matters such as euthanasia or procuring organs from brain-dead patients. These differing orientations have resulted in some of the most enduring conflicts in biomedical decision-making with roots in the earliest strands of philosophical discourse. Through continually grappling with questions over matters of death, we continually step closer to clarity, even if certainty (...) on these matters remains necessarily as elusive as death itself.

The ethical and political dilemmas raised byInformation and Communication Technology (ICT)have only just begun to be understood. Theimpact of centralised data collection, masscommunication technologies or the centrality ofcomputer technology as a means of accessingimportant social institutions, all poseimportant ethical and political questions. As away of capturing some of these effects I willcharacterise them in terms of the type of powerand, more particularly, the ‘Power-over’ peoplethat they exercise. My choice of thisparticular nomenclature is that it allows us todescribe, firstly, how specific (...) technologiesoperate and second, exactly what sorts ofconstraints they impose on people. The reasonfor this focus has to do with a further aim ofthe essay, which is to intervene in aparticular type of debate that is often hadaround the appropriate use and scope oftheories of power that are employed in thinkingabout ICT, especially those theories associatedwith the work of Michel Foucault. There isconsiderable use of his work in computerethics, but my claim will be that despite theproductive uses of his work in the areas ofsurveillance, for instance, it does not exhaustthe larger potential of his work on power and,in part, `government.' I will argue that inorder to properly understand the politicalimpact of some aspects of ICT, especially thedigital divide, one needs an account of howpower operates that includes more traditionaltypes of power-over. To the extent that I willdeal with these concerns, the paper is both acontribution to debates about the nature andscope of Foucault's theory of power and to theissue of the effects of the digital divide.

Mathematicians use the word ‘deep’ to convey a high appreciation of a concept, theorem, or proof. This paper investigates the extent to which the term can be said to have an objective character by examining its first use in mathematics. It was a consequence of Gauss's work on number theory and the agreement among his successors that specific parts of Gauss's work were deep, on grounds that indicate that depth was a structural feature of mathematics for them. In contrast, French (...) mathematicians had a less structural, more problem-oriented approach to mathematics and did not speak of depth so readily. (shrink)

Many people in desperate need of an organ will die on waiting lists for transplantation or face increased morbidity because of their wait. This circumstance is particularly troubling since many viable organs for transplantation go unused when individuals fail to participate in their local organ donation system. In this paper, I consider whether participating in organ transplantation should be considered a form of a rescue of others from the great harms caused by a shortage in transplantable organs. Specifically, I consider (...) whether cadaver organ transplantation is a case of an easy rescue. If so, participation in cadaver organ transplantation will be a duty rather than a supererogatory act.1 This question is important in illuminating individual duties to participate in organ transplantation. Moreover, as I will argue, it has repercussions for community-wide policies for enrolling individuals in transplantation schemes. -/- In the first section of this paper, I tie cadaver organ transplantation to the duty to rescue others from great harm when it is easy to do so. Given the number of persons who will die or be greatly harmed without transplanted organs, the transfer of organs upon death is seemingly similar to other, classical cases of easy rescue. In the second section, I consider objections to this proposal on the ground that cadaver organ transplantation is structurally dissimilar to classical rescue cases, especially given uncertainty over when and to whom organs will be transplanted, if they are transplanted at all. In the third section, I consider the objection that cadaver organ transplantation is a demanding, rather than easy, rescue. While I grant that cadaver organ transplantation will be demanding for some persons, I argue that there remain many cases where it will be an easy rescue. In the final section, I consider the policy implications of my argument. In particular, I argue that understanding cadaver organ transplantation as a duty should shift the debate over opt-out, opt-in, and mandatory choice procedures for participating in organ transplantation upon death. While different systems will be appropriate for different communities, understanding transplantation as a duty in some cases helps to justify an opt-out system. (shrink)

The ambition of this volume is twofold: to provide a comprehensive overview of the field and to serve as an indispensable reference work for anyone who wants to work in it. For example, any philosopher who hopes to make a contribution to the topic of the classical-quantum correspondence will have to begin by consulting Klaas Landsman’s chapter. The organization of this volume, as well as the choice of topics, is based on the conviction that the important problems in the philosophy (...) of physics arise from studying the foundations of the fundamental theories of physics. It follows that there is no sharp line to be drawn between philosophy of physics and physics itself. Some of the best work in the philosophy of physics is being done by physicists, as witnessed by the fact that several of the contributors to the volume are theoretical physicists: viz., Ellis, Emch, Harvey, Landsman, Rovelli, ‘t Hooft, the last of whom is a Nobel laureate. Key features - Definitive discussions of the philosophical implications of modern physics - Masterly expositions of the fundamental theories of modern physics - Covers all three main pillars of modern physics: relativity theory, quantum theory, and thermal physics - Covers the new sciences grown from these theories: for example, cosmology from relativity theory; and quantum information and quantum computing, from quantum theory - Contains special Chapters that address crucial topics that arise in several different theories, such as symmetry and determinism - Written by very distinguished theoretical physicists, including a Nobel Laureate, as well as by philosophers - Definitive discussions of the philosophical implications of modern physics - Masterly expositions of the fundamental theories of modern physics - Covers all three main pillars of modern physics: relativity theory, quantum theory, and thermal physics - Covers the new sciences that have grown from these theories: for example, cosmology from relativity theory; and quantum information and quantum computing, from quantum theory - Contains special Chapters that address crucial topics that arise in several different theories, such as symmetry and determinism - Written by very distinguished theoretical physicists, including a Nobel Laureate, as well as by philosophers.

The dominated convergence theorem implies that if is a sequence of functions on a probability space taking values in the interval [0, 1], and converges pointwise a.e., then converges to the integral of the pointwise limit. Tao [26] has proved a quantitative version of this theorem: given a uniform bound on the rates of metastable convergence in the hypothesis, there is a bound on the rate of metastable convergence in the conclusion that is independent of the sequence and the underlying (...) space. We prove a slight strengthening of Tao’s theorem which, moreover, provides an explicit description of the second bound in terms of the first. Specifically, we show that when the first bound is given by a continuous functional, the bound in the conclusion can be computed by a recursion along the tree of unsecured sequences. We also establish a quantitative version of Egorov’s theorem, and introduce a new mode of convergence related to these notions. (shrink)

From ancient times to the beginning of the nineteenth century, mathematics was commonly viewed as the general science of quantity, with two main branches: geometry, which deals with continuous quantities, and arithmetic, which deals with quantities that are discrete. Mathematical logic does not fit neatly into this taxonomy. In 1847, George Boole [1] offered an alternative characterization of the subject in order to make room for this new discipline: mathematics should be understood to include the use of any symbolic calculus (...) “whose laws of combination are known and general, and whose results admit of a consistent interpretation.” Depending on the laws chosen, symbols can just as well be used to represent propositions instead of quantities; in that way, one can consider calculations with propositions on par with more familiar arithmetic calculations. Despite Boole’s efforts, logic has always held an uncertain place in the mathematical community. This can partially be attributed to its youth; while number theory and geometry have their origins in antiquity, mathematical logic did not emerge as a recognizable discipline until the latter half of the nineteenth century, and so lacks the provenance and prestige of its elder companions. Furthermore, the nature of the subject matter serves to set it apart; as objects of mathematical study, formulas and proofs do not have the same character as groups, topological spaces, and measures. Even distinctly mathematical branches of contemporary logic, like model theory and set theory, tend to employ linguistic classifications and measures of complexity that are alien to other mathematical disciplines. The Birth of Model Theory, by Calixto Badesa, describes a seminal step in the emergence of logic as a mature mathematical discipline. As its title suggests, the focus is on one particular result, now referred to as the L¨owenheim-Skolem theorem, as presented in a paper by L¨owenheim in 1915. But the book is, more broadly, about the story of the logic community’s gradual coming to the modern distinction between syntax and semantics, that is, between systems of symbolic expressions and the meanings that can be assigned to them..

On September 6, 2004, using the Isabelle proof assistant, I verified the following statement: (%x. pi x * ln (real x) / (real x)) ----> 1 The system thereby confirmed that the prime number theorem is a consequence of the axioms of higher-order logic together with an axiom asserting the existence of an infinite set. All told, our number theory session, including the proof of the prime number theorem and supporting libraries, constitutes 673 pages of proof scripts, or roughly 30,000 (...) lines. This count includes about 65 pages of elementary number theory that we had at the outset, developed by Larry Paulson and others; also about 50 pages devoted to a proof of the law of quadratic reciprocity and properties of Euler’s ϕ function, neither of which are used in the proof of the prime number theorem. The page count does not include the basic HOL library, or properties of the real numbers that we obtained from the HOL-Complex library. (shrink)

Hilbert’s program: • Formalize abstract, infinitary, nonconstructive mathematics. • Prove consistency using only finitary methods.

In the theory of programming languages, type inference is the process of inferring the type of an expression automatically, often making use of information from the context in which the expression appears. Such mechanisms turn out to be extremely useful in the practice of interactive theorem proving, whereby users interact with a computational proof assistant to constructformal axiomatic derivations of mathematical theorems. This article explains some of the mechanisms for type inference used by the "Mathematical Components" project, which is working (...) towards a verification of the Feit-Thompson theorem. (shrink)

The first part of this paper surveys the current literature in the history of nineteenth-century mathematics in order to show that the question “Did the increasing abstraction of mathematics lead to a sense of anxiety?” is a new and valid question. I argue that the mathematics of the nineteenth century is marked by a growing appreciation of error leading to a note of anxiety, hesitant at first but persistent by 1900. This mounting disquiet about so many aspects of mathematics after (...) 1850 is seldom discussed. The second part explores the issue of anxiety in mathematical life through an interesting account of an address made by a mathematician in 1911, Oscar Perron. The third and final part ventures some conclusions about the value of anxiety as a question for historians of mathematics to pursue. (shrink)

ArgumentIt would have been easy for a less imaginative historian of mathematics than Herbert Mehrtens to have portrayed the work of Hilbert, Hausdorff, and other modernists as pioneers, and those who did not subscribe to their program as people who failed, were not good enough to make the turn, and were eventually and convincingly left behind. That he did not do so is not only because this would have been a shallow, selective view of the facts: it is incompatible with (...) his Foucauldian approach to the relations between knowledge and power. Instead, he defined what I see as the most intriguing category of actor in his Moderne—Sprache—Mathematik (1990), the Gegenmoderner, or counter-moderns. The three men who characterize this position are Felix Klein, Henri Poincaré, and Luitzen Brouwer, and each merits a section in the book.Of the three, Poincaré is the hardest to contain within that category. The range of his work, the nature of his influence, and the shifting standards by which mathematical significance has been evaluated by mathematicians, historians of mathematics, and society at large, all contribute to the problem. After thirty years, the methodological presumptions and aspirations of historians of mathematics have also changed, and I shall suggest that one way to appreciate the richness of Mehrtens’ book, to gain insight into what is meant by mathematical modernism, and to acknowledge a generation of work by other historians since 1990, is to re-examine aspects of Poincaré’s life and work and scholarship about him. Prodded by remarks by Leo Corry, Moritz Epple, and David Rowe, I shall suggest that the simple but useful dichotomy modern/counter-modern must be seen as a way into a more complicated situation, one in which different aspects of mathematics, specifically applied mathematics and the relationship of mathematics to contemporary physics, require fresh accounts of the role of modern mathematics in society.

This essay aims to examine metropolitan cities of Latin America with two aspects of the literature in anthropology, history, and sociology in mind. First, the essay addresses an imbalanced focus on cities in the USA and Canada by sketching the significance of migration, creation, and urban development in four major metropolises of Latin America. Second, in place of a framework of urban imaginaries, which has dominated the sociology of Latin American cities in recent years, I argue for a more precise (...) notion of metropolitan imaginaries that better frames the creativity of particular cities and their level of integration into international and regional networks. With this more precise notion, I distinguish southern cities as highly connected places, which attract migrants and bring economic and cultural traffic to their shores, ports, plazas, and streets. They are lively centers of Atlantic modernity with connections that generate greater magnitude for creativity and, as such, bear international significance as places of architecture and urban design. In their informal settlements, impulses of organic creation further distinguish southern metropolises from their North American counterparts. The quality of international and regional connections distinguishes these cities from other urban centers in Latin America, a point underestimated in the literature on urban imaginaries. In this essay, I examine 19th and 20th-century Buenos Aires, Mexico City, São Paulo, and Rio de Janeiro. Each is distinguished from most cities by the magnitude of migration, the diversity of their populations, and the connections they have to global and regional developments. Crucially, each one stands out for the quality and impact of their metropolis-making, particularly in creative architecture and urban design. (shrink)

This paper asks how we should regard the laws and customs of armed conflict, and specifically the rule prohibiting the targeting of civilians. What view should we take of the moral character and significance of such rules? Some philosophers have suggested that they are best regarded as useful conventions. This view is sometimes motivated by a "deep moral critique" of the rule protecting civilians: Jeff McMahan believes for example that the existing rules protect some who ought to be liable to (...) attack (on account of their having voluntarily contributed to the injustice or aggression being resisted). He thinks we would be better off with a different principle of discrimination in warfare. But McMahan acknowledges that for the time being we must stick with the rules that we have. The present paper does five things: (1) it explores and takes further some of McMahan's insights about the importance of existing positive law in this area; (2) it argues that some of the features that philosophers find problematic with the rule offering blanket protection to all civilians have to do with administrability; (3) it raises some questions about whether the rule protecting civilians can really be regarded as a convention (and it argues that certainly it cannot be regarded as a "Lewis-convention" in a strict sense); (4) to the extent that the rule can be regarded as conventional, the paper argues that it remains a deadly serious moral rule, partly because of the circumstances of death and destruction in which it operates and which it tries to ameliorate, and partly on account of its fragility. The fifth point is the most important. (5) The rule protecting civilians does not operate in circumstances in which, apart form positive law, civilians like everyone would be liable to attack. The rule operates against a moral background in which all deliberate killing is to be regarded as murder; some deliberate killings (of combatants) are privileged in warfare; but the rule about civilians reflects the fact that this is a strictly limited privilege and that those who target civilians do not get the benefit of it. Changing our view of the default position in this way enables us to better understand the distinctive work that this rule does. (shrink)

For a quarter of a century, the Council for Responsible Genetics has provided a unique historical lens into the modern history, science, ethics, and politics of genetic technologies.

Steven M. Cahn presented a fascinating and recalcitrant puzzle. Imagine that you own stock in a company that has undertaken an immoral course of action. Most people believe that selling the stock is the right thing to do. But if you sell the stock, you thereby abet the buyer in an immoral course of action, namely the buyer’s coming to own tainted stock. Is principled divestiture possible? If so, what are the moral grounds on which principled divestiture stands? These questions (...) have proven difficult. Cahn answered many attempted replies to his puzzle. In this journal, Saul Smilansky also attempted to answer the divestiture puzzle. Smilansky concluded, “Attempting to divest by offering the stock for sale is, however, morally problematic. It is problematic because it involves the bad faith of putting something forward as morally acceptable while claiming it to be morally tainted.” Smilansky continued, “One needs to get rid of the stock and take it off the market at the same time, i.e., make it impossible for others to purchase the stock.” Smilansky thereby implies that one should destroy the stock. However, Cahn had already replied to this move, noting that destroying one’s stock would increase the moral culpability of other owners. (shrink)
