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)

Issues pertaining to sex and gender continue to be some of the most hotly debated topics of our time. While many of the most heated disputes occur at the level of politics and public policy, metaphysics, too, has a crucial role to play in these debates. In this essay, I explore several key metaphysical debates concerning sex and gender through the lenses of two important areas in contemporary metaphysics: the metaphysics of essence and the ontology of the human person. The (...) goal here is not to advocate any particular position on these issues, but to show how the tools of contemporary metaphysics can help to offer a more comprehensive map of the conceptual terrain, indicating where major areas of agreement can be found and where the most important disagreements really lie.

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)

Lady Mary Shepherd’s critique of Hume’s account of causation, his worries about knowledge of matters of fact, and the contention that it is possible for the course of nature to spontaneously change relies primarily on three premises, two of which – that objects are merely bundles of qualities and that the qualities of an object are individuated by the causal powers contributed by those qualities – anticipate contemporary metaphysical views in ways that she should be getting credit for. The remaining (...) premise – that it is impossible for an object to begin to exist uncaused – seems more old fashioned. I argue that Shepherd can do without her old-fashioned premise and that she provides the materials for arguing that her remaining premises demonstrate a stronger anti-Humeanism than is maintained even by the contemporary representatives of those views, even though she may have to concede more to Humeanism than she would like.

I have two main aims. The first is general, and more philosophical. The second is specific, and more closely related to physics. The first aim is to state my general views about laws and causation at different ”levels’. The main task is to understand how the higher levels sustain notions of law and causation that ”ride free’ of reductions to the lower level or levels. I endeavour to relate my views to those of other symposiasts. The second aim is to (...) give a framework for describing dynamics at different levels, emphasizing how the various levels’ dynamics can mesh or fail to mesh. This framework is essentially that of elementary dynamical systems theory. The main idea will be, for simplicity, to work with just two levels, dubbed ”micro’ and ”macro’, which are related by coarse-graining. I use this framework to describe, in part, the first four of Ellis’ five types of top-down causation. (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 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)

What can Stoicism offer to contemporary debates about forgiveness? Given their outright rejection of a reactive attitudes framework for responding to wrongdoing and their bold suggestions of how to revise our moral practices, the Stoics provide a valuable lens through which to re-evaluate various central claims in the debates about forgiveness. In this chapter, I highlight four common assumptions that the Stoics would consider problematic: firstly, that forgiveness is opposed to justice; secondly, that anger and resentment are necessary for registering (...) wrongdoing; thirdly, that anger and resentment are generally reliable at tracking the severity of wrongdoing; fourthly, that reconciliation with wrongdoers is an option rather than an imperative of virtue. Insofar as the Stoics provide defensible and often compelling alternatives to these positions, Stoicism offers a number of philosophical resources to re-conceptualize the way we think about forgiveness and suggests ways in which forgiveness might be better integrated into a virtue ethical framework.

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)

This article investigates the history of the relation between idealism and pragmatism by examining the importance of the French idealist Charles Renouvier for the development of William James's ‘Will to Believe’. By focusing on French idealism, we obtain a broader understanding of the kinds of idealism on offer in the nineteenth century. First, I show that Renouvier's unique methodological idealism led to distinctively pragmatist doctrines and that his theory of certitude and its connection to freedom is worthy of reconsideration. Second, (...) I argue that the technical vocabulary and main structure of the argument from the ‘Will to Believe’ depend upon Renouvier's idealist theory of knowledge and psychology of belief, and that taking account of this line of influence is of crucial importance for establishing the correct interpretation of James's work.

Using a social exchange perspective of narcissism as the foundation for study hypotheses, this study explored the relationship between leaders’ narcissism and the well-being of both leaders and subordinates at the individual and group levels. Results from a sample of 1017 subordinates working under 424 leaders generally support the hypothesized models finding leaders’ narcissism negatively relates to leader-member exchange, and that LMX subsequently relates to subordinates’ job satisfaction and emotional exhaustion. At the group level, leaders’ narcissism also negatively relates to (...) three forms of leaders’ personal well-being but these relationships go through average LMX. Elaboration on theoretical and empirical implications for business ethics is offered to provide a clearer direction for future research in this area. (shrink)

Time, along with concepts as space and matter, is bound to be a central concept of any physical theory. The chapter first discusses how time is treated similarly in quantum and classical theories. It then provides a few references on time‐reversal. The chapter discusses three chosen authors' (Paul Busch, Jan Hilgevoord and Jos Uffink) clarifications of uncertainty principles in general. Next, the chapter follows Busch in distinguishing three roles for time in quantum physics. They are external time, intrinsic time and (...) observable time. It also provides a brief discussion on time operators, in particular Pauli's influential proof. Finally, the chapter talks about time‐energy uncertainty principles with intrinsic times. (shrink)

Why does Foucault's work continue to be of central importance in current debates in sociology, political science and philosophy? Why do we still read him as a guide to contemporary social and cultural life? Foucault's work presents a provocative challenge to orthodox, habitual forms of belief and practice. The Later Foucault, with an impressive interdisciplinary focus, argues that one of the keys to understanding Foucault is his political thought. It is this which he expressed clearly in his last writings and (...) which pulled together his earlier interests in power, agency and subjectivity. In this volume a distinguished array of Foucauldian scholars and commentators on politics explore the significance of these l. (shrink)

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.

It is often suggested that, since the state of affairs in which God creates a good universe is better than the state of affairs in which He creates nothing, a perfectly good God would have to create that good universe. Making use of recent work by Christine Korgaard on the relational nature of the good, I argue that the state of affairs in which God creates is actually not better, due to the fact that it is not better for anyone (...) or anything in particular. Hence, even a perfectly good God would not be compelled to create a good universe. (shrink)

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)

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)

As our civilization careens toward climate breakdown, ecological destruction, and gaping inequality, people are losing their existential moorings. The dominant worldview of disconnection, which tells us we are split between mind and body, separate from each other, and at odds with the natural world, has been invalidated by modern science. Award-winning author, Jeremy Lent, investigates humanity's age-old questions -- Who am I? Why am I? How should I live? -- from a fresh perspective, weaving together findings from modern systems thinking, (...) evolutionary biology, and cognitive neuroscience with insights from Buddhism, Taoism, and Indigenous wisdom. The result is a breathtaking accomplishment: a rich, coherent worldview based on a deep recognition of connectedness within ourselves, between each other, and with the entire natural world. It offers a compelling foundation for a new philosophical framework that could enable humanity to thrive sustainably on a flourishing Earth. The Web of Meaning is for everyone looking for deep and coherent answers to the crisis of civilization. -- Amazon. (shrink)

In Science, Truth, and Democracy, Philip Kitcher challenges the view that science has a single, context‐independent, goal, and that the pursuit of this goal is essentially immune from moral critique. He substitutes a context‐dependent account of science’s goal, and shows that this account subjects science to moral evaluation. I argue that Kitcher’s approach must be modified, as his account of science ultimately must be explicated in terms of moral concepts. I attempt, therefore, to give an account of science’s goal that (...) is free of direct moral entanglements but still makes this goal context‐dependent and leaves the choice of which projects to pursue subject to moral scrutiny.

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.

Jamin Asay has recently argued that deflationists about the concept of truth cannot satisfactorily account for our alethic desires, i.e., those of our desires that pertain to the truth of our beliefs. In this brief reply, I show how deflationists can draw on well‐established psychological findings on framing effects to explain how the concept of truth behaves within the scope of our alethic desires.

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. Since 1983 the Council has had leading scientists, activists, science writers, and public health advocates researching and reporting on a broad spectrum of issues, including genetically engineered foods, biological weapons, genetic privacy and discrimination, reproductive technologies, and human cloning. Biotechnology in Our Lives examines how these issues affect us daily whether we realize (...) it or not. Written for the nonscientist, it looks at the many applications of genetics on the world around us by posing questions such as: What should we know about genetics and childbirth? Can our genes keep us from qualifying for health insurance? Can gene therapy cure cancer? Is behavior genetically determined? Why would the FBI want our genes? Are foreign genes in our food? And much more Ultimately, this definitive book on the subject also encourages us to think about the social, environmental, and moral ramifications of where this technology is taking us. (shrink)

I argue against the idea (made popular by H.L.A. Hart) that the key to a legal system is its "rule of recognition." I argue that much of the work allegedly done by a rule of recognition is either done by a different kind of secondary rule (what Hart called "a rule of change") or it is not done at all (and doesn't have to be done). A rule of change tells us the procedures that must be followed and the substantive (...) conditions that must be satisfied if law is to be changed legislatively; and a judge "recognizes" changes simply by using this checklist. In common law, there is no clear rule of change (because we are profoundly ambivalent about judicial lawmaking). But we get by without one, and without a determinate rule of recognition that would tell us precisely how to infer rules from precedents. It is quite liberating, really, to abandon the idea of a rule of recognition. Apart from anything else, it relieves us from having to participate in endless debates about whether the US Constitution is (or contains) a rule of recognition for American law. The Constitution contains rules of change; that's what matters. (shrink)

We argue that the language of Zermelo Fraenkel set theory with definitions and partial functions provides the most promising bedrock semantics for communicating and sharing mathematical knowledge. We then describe a syntactic sugaring of that language that provides a way of writing remarkably readable assertions without straying far from the set-theoretic semantics. We illustrate with some examples of formalized textbook definitions from elementary set theory and point-set topology. We also present statistics concerning the complexity of these definitions, under various complexity (...) measures. (shrink)

Although sensorimotor contingencies may explain visual perception, it is difficult to extend this concept to speech perception. However, the basic concept of perception as active hypothesis testing using attention does extend well to speech perception. We propose that the concept of sensorimotor contingencies can be broadened to sensory-attentional contingencies, thereby accounting for speech perception as well as vision.

Since its introduction just over two decades ago, evidence-based medicine (EBM) has come to dominate medical practice, teaching, and policy. There are a growing number of textbooks, journals, and websites dedicated to EBM research, teaching, and evidence dissemination. EBM was most recently defined as a method that integrates best research evidence with clinical expertise and patient values and circumstances in the treatment of patients. There have been debates throughout the early 21st century about what counts as good research evidence between (...) EBM proponents and philosophical critics and even within the EBM community itself. Similar controversy arises about the relative worth of patient values and clinical expertise (and how these can be integrated). EBM has also evolved in ways that have come under scrutiny. Specifically, policymakers have used EBM research methodology to increase the relative importance of clinical guidelines that some clinicians have argued are tyrannical. Philosophers have addressed all of these controversies, and with very few exceptions have been critical of EBM. In addition most philosophical attention has been on the epistemic role of Randomization and evidence hierarchies, with relatively little attention being paid to the role of Diagnosis, expertise, patient values, and Systematic Reviews within EBM.

On New year's Eve 1992 a man suffering from schizophrenia climbed into a lions' cage at the London Zoo and was badly mauled. This event provoked a full-scale moral panic among the media and government, the tragedy seeming to violate many of the comfortable myths about progress in psychiatry, echoing the impact of the civil war in former Yugoslavia which had shattered the hope of an era of unbroken European peace following the end of the cold war. Whatever we may (...) wish in reality the lion does not lie down with the lamb. Daniel the visionary, the interpreter of dreams, the one who asserted that his God, the God of angels and saints with power over man and beasts would eventually endure, while all earthly kings were found wanting, emerged from the lions’ den unscathed—but secular, psychiatric, suffering, decarcer-ated, visionless, late-twentieth-century man does not.

At the heart of the provocation defence lies the assumption that the excusatory focus should be the all-too-human and supposedly characteristic tendency to act in a spontaneously retaliatory fashion, when provocation has led to great anger. What if this is not the characteristic reaction of someone who acts for mixed motives, when not only angry at but also fearful of the provoker? Making such cases central to a plea of provocation would reshape the defence so as both to restrict and (...) to expand its availability in important ways, thus meeting some common criticisms of its current operation. The requirement that a defendant should have feared, as well as been angry at, a provoker, operates as what can be called a ‘subjective’ limiting condition, a new kind of limiting condition to set alongside more familiar ‘objective’ limiting conditions, such as the reasonable person test.
