The main aim of the book is to provide a good understanding of a range of semantic phenomena and issues in semantics, adopting a truth-conditional account of meaning, but without using a compositional formalism. The book assumes no particular background in linguistics of philosophy, and all the technical tools used are explained as they are introduced. They style is accessible, with numerous examples.

One of Martin Heidegger’s enduring philosophical legacies is his overall vision of what it is to be us. We—whoever that turns out to include—are cases of Dasein, and as such we are distinctively open to entities, including others and ourselves. In this essay, I paint a picture of that openness that aims to capture why Heidegger’s vision has so powerfully gripped so many. Drawing on Heidegger’s thought both early and late, I present a synoptic view of us as open to (...) the encounter with entities' bursting forth into presencing. We can be more or less closed off to this upsurge, but we can also allow it in its full power: in philosophical and poetic openness. I draw on Borgmann, Buber, Plato’s Socrates, Rilke, and others to capture our openness at its Heideggerian best—and we ourselves at our best, showing up radiantly for encounter. (shrink)

This presentation of a system of propositional logic is a foundational paper for systems of illocutionary logic. The language contains the illocutionary force operators '' for assertion and ' ' for supposition. Sentences occurring in proofs of the deductive system must be prefixed with one of these operators, and rules of take account of the forces of the sentences. Two kinds of semantic conditions are investigated; familiar truth conditions and commitment conditions. Accepting a statement A or rejecting A commits a (...) person to accepting some statements (the symbol '' marks this value), to rejecting some statements (), and will leave the person uncommitted with respect to others (). Commitment valuations assign the values to sentences of ; such a valuation is conceived as reflecting the beliefs/knowledge of a particular person. This paper explores the relations between truth conditions and commitment conditions, and between semantic concepts defined in terms of these conditions. (shrink)

Although the principle of fair subject selection is a widely recognized requirement of ethical clinical research, it often yields conflicting imperatives, thus raising major ethical dilemmas regarding participant selection. In this paper, we diagnose the source of this problem, arguing that the principle of fair subject selection is best understood as a bundle of four distinct sub-principles, each with normative force and each yielding distinct imperatives: (1) fair inclusion; (2) fair burden sharing; (3) fair opportunity; and (4) fair distribution of (...) third-party risks. We first map out these distinct sub-principles, and then identify the ways in which they yield conflicting imperatives for the design of inclusion and exclusion criteria, and the recruitment of participants. We then offer guidance for how decision makers should navigate these conflicting imperatives to ensure that participants are selected fairly. (shrink)

This paper uses the resources of illocutionary logic to provide a new understanding of the Liar Paradox. In the system of illocutionary logic of the paper, denials are irreducible counterparts of assertions; denial does not in every case amount to the same as the assertion of the negation of the statement that is denied. Both a Liar statement, (a) Statement (a) is not true, and the statement which it negates can correctly be denied; neither can correctly be asserted. A Liar (...) statement, more precisely, an attempted Liar statement, fails to fulfill conditions essential to statements, but no linguistic rules are violated by the attempt. Ordinary language, our ordinary practice of using language, is not inconsistent or incoherent because of the Liar. We are committed to deny Liars, but not to accept or assert them. This understanding of the Liar Paradox and its sources cannot be fully accommodated in a conventional logical system, which fails to mark the distinction between sentences/statements and illocutionary acts of accepting, rejecting, and supposing statements.

Virtues commonly associated with physicians and other healthcare professionals include empathy, respect, kindness, compassion, trustworthiness, and many more. Building upon the work of Bortolloti, Murphy-Hollies, and others, I suggest that curiosity as a virtue has an integral role to play in healthcare, namely, in helping to make those who are invisible, visible. Practicing the virtue of curiosity enables one to engage with and explore the experiences of patients and contributes toward building a physician–patient relationship of trust. As the perspectives and (...) experiences of patients can be too often dismissed or lost within medical settings, curiosity can allow physicians to deeply know their patients, and thus provide better care. However, caution must be exercised so as to not to venture into inappropriate curiosity, where questions are asked for improper reasons or to help satisfy the personal interest of physicians. Finally, I sketch out two cases—on chronic pain and on vaccine hesitancy—to illustrate where curiosity can play a valuable role. (shrink)

This paper further develops the system of illocutionary logic presented in ?Propositional logic of supposition and assertion? (Notre Dame Journal of Formal Logic 1997, 38, 325-349) to accommodate an ?I believe that? operator and resolve Moore's Paradox. This resolution is accomplished by providing both a truth-conditional and a commitment-based semantics. An important feature of the logical system is that the correctness of some arguments depends on who it is that makes the argument. The paper then shows that the logical system (...) can be expanded to resolve the surprise execution paradox puzzle. The prisoner's argument showing that he can't be executed by surprise is correct but his beliefs are incoherent. The judge's beliefs (and our beliefs) about this situation are not incoherent.

Daniel Whiting’s excellent new book, The Range of Reasons (2022), makes a number of noteworthy contributions to the philosophical literature on reasons and normativity. A good deal has been written on normative reasons, and it is no easy thing to make novel and promising arguments. Yet, this is what Whiting manages to do. We are sympathetic to some of his ideas and critical of others. It makes sense for us to focus on the first half of his book, where Whiting (...) presents two accounts of normative reasons (the first superseded by, although possibly also compatible with, the second). We welcome this opportunity to clarify our own current views on the nature of normative reasons by contrasting them with Whiting’s views. (shrink)

How do things persist? Are material objects spread out through time just as they are spread out through space? Or is temporal persistence quite different from spatial extension? This key question lies at the heart of any metaphysical exploration of the material world, and it plays a crucial part in debates about personal identity and survival. This book explores and compares three theories of persistence — endurance, perdurance, and stage theories — investigating the ways in which they attempt to account (...) for the world around us. Having provided valuable clarification of its two main rivals, the book concludes by advocating stage theory. Such a basic issue about the nature of the physical world naturally has close ties with other central philosophical problems. This book includes discussions of change and parthood, of how we refer to material objects at different times, of the doctrine of Humean supervenience, and of the modal features of material things. In particular, it contains new accounts of the nature of worldly vagueness, and of what binds material things together over time, distinguishing the career of a natural object from an arbitrary sequence of events. Each chapter concludes with a reflection about the impact of these metaphysical debates upon questions about our personal identity and survival. (shrink)

Stereotypes sometimes lead us to make poor judgements of other people, but they also have the potential to facilitate quick, efficient, and accurate judgements. How can we discern whether any individual act of stereotyping will have the positive or negative effect? How Stereotypes Deceive Us addresses this question. It identifies various factors that determine whether or not the application of a stereotype to an individual in a specific context will facilitate or impede correct judgements and perceptions of the individual. It (...) challenges the thought that stereotyping only and always impedes correct judgement when the stereotypes that are applied are inaccurate, failing to reflect social realities. It argues instead that stereotypes that reflect social realities can lead to misperceptions and misjudgements, and that inaccurate but egalitarian social attitudes can therefore facilitate correct judgements and accurate perceptions. The arguments presented in this book have important implications for those who might engage in stereotyping and those who are at risk of being stereotyped. They have implications for those who work in healthcare and those who have mental health conditions. How Stereotypes Deceive Us provides a new conceptual framework-evaluative dispositionalism-that captures the epistemic faults of stereotypes and stereotyping, providing conceptual resources that can be used to improve our own thinking by avoiding the pitfalls of stereotyping, and to challenge other people's stereotyping where it is likely to lead to misperception and misjudgement.

This article reflects on the relevance and applicability of the Belmont Report nearly four decades after its original publication. In an exploration of criticisms that have been raised in response to the report and of significant changes that have occurred within the context of biomedical research, five primary themes arise. These themes include the increasingly vague boundary between research and practice, unique harms to communities that are not addressed by the principle of respect for persons, and how growing complexity and (...) commodification in research have shed light on the importance of transparency. The repercussions of Belmont's emphasis on the protection of vulnerable populations is also explored, as is the relationship between the report's ethical principles and their applications. It is concluded that while the Belmont Report was an impressive response to the ethical issues of its day, the field of research ethics involving human subjects may have outgrown it. (shrink)

What is epistemic self-trust? There is a tension in the way in which prominent accounts answer this question. Many construe epistemic trust in oneself as no more than reliance on our sub-personal cognitive faculties. Yet many accounts – often the same ones – construe epistemic trust in others as a normatively laden attitude directed at persons whom we expect to care about our epistemic needs. Is epistemic self-trust really so different from epistemic trust in others? I argue that it is (...) not. We certainly do rely on our cognitive faculties to achieve epistemic ends; but I argue that we also have the normatively rich sort of epistemic trust in ourselves. Moreover, there is a theoretical need for this normatively rich notion of epistemic self-trust: positing it yields the best account of how we secure important epistemic goods, including knowledge and recognition as knowers. I argue this by giving an account of epistemic trust in others and showing that it can be generalized to epistemic trust in oneself. (shrink)

Perceptual grouping has traditionally been thought to be governed by innate, universal principles. However, recent work has found differences in Japanese and English speakers' non-linguistic perceptual grouping, implicating language in non-linguistic perceptual processes (Iversen, Patel, & Ohgushi, 2008). Two experiments test Japanese- and English-learning infants of 5-6 and 7-8 months of age to explore the development of grouping preferences. At 5-6 months, neither the Japanese nor the English infants revealed any systematic perceptual biases. However, by 7-8 months, the same age (...) as when linguistic phrasal grouping develops, infants developed non-linguistic grouping preferences consistent with their language's structure (and the grouping biases found in adulthood). These results reveal an early difference in non-linguistic perception between infants growing up in different language environments. The possibility that infants' linguistic phrasal grouping is bootstrapped by abstract perceptual principles is discussed. (shrink)

In their article on the limited duty to reinterpret genetic variants, Watts and Newson argue that clinical labs are not morally obligated to conduct routine reinterpretation despite its potential clinical and personal value.1 We endorse the authors’ argument for a circumscribed duty to reclassify genomic variants in certain cases, including to promote diagnostic equity for racial and ethnic minority populations that have been historically excluded from and exploited by genomic research and medicine. However, given the history and resilience of scientific (...) racism, the use of socially constructed racial and ethnic categories to enhance diagnostic equity raises several ethical and practical challenges. In the short term, using socially constructed racial and ethnic categories to identify patients for variant reclassification is a practical approach for addressing concerns of diagnostic equity. In contrast, diagnostic accuracy depends on patients’ genetic similarity to reference genomes, rather than their socially determined race or ethnicity.2 Thus, in the long term, securing both diagnostic equity and diagnostic accuracy through targeted variant reclassification will require a shift away from relying on race and ethnicity and towards assessing genetic similarity. Critically, the identification of patients for genomic variant reclassification using socially constructed race or ethnicity runs the risk of perpetuating the harmful …. (shrink)

In this article we argue that nanotechnology represents an extraordinary opportunity to build in a robust role for the social sciences in a technology that remains at an early, and hence undetermined, stage of development. We examine policy dynamics in both the United States and United Kingdom aimed at both opening up, and closing down, the role of the social sciences in nanotechnologies. We then set out a prospective agenda for the social sciences and its potential in the future shaping (...) of nanotechnology research and innovation processes. The emergent, undetermined nature of nanotechnologies calls for an open, experimental, and interdisciplinary model of social science research. (shrink)

Conspiracy theorists believe that powerful agents are conspiring to achieve their nefarious aims and also to orchestrate a cover-up. People who suffer from impostor syndrome believe that they are not talented enough for the professional positions they find themselves in, and that they risk being revealed as inadequate. These are quite different outlooks on reality, and there is no reason to think that they are mutually reinforcing. Nevertheless, there are intriguing parallels between the patterns of trust and distrust which underpin (...) both conspiracy theorising and impostor thinking. In both cases subjects distrust standard sources of information, instead regarding themselves as especially insightful into the underlying facts of the matter. In both cases, seemingly-anomalous data takes on special significance. And in both cases, the content of belief dictates the epistemic behaviour of the believer. This paper explores these parallels, to suggest new avenues of research into both conspiracy theorising and impostor syndrome, including questions about whether impostor syndrome inevitably involves a personal failure of rationality, and issues about how, if at all, it is possible to convince others to abandon either conspiracy theories or impostor attitudes.

It has been argued that humans can face an ethical/epistemic dilemma over the automatic stereotyping involved in implicit bias: ethical demands require that we consistently treat people equally, as equally likely to possess certain traits, but if our aim is knowledge or understanding our responses should reflect social inequalities meaning that members of certain social groups are statistically more likely than others to possess particular features. I use psychological research to argue that often the best choice from the epistemic perspective (...) is the same as the best choice from the ethical perspective: to avoid automatic stereotyping even when this involves failing to reflect social realities in our judgements. This argument has an important implication: it shows that it is not possible to successfully defend an act of automatic stereotyping simply on the basis that the stereotype reflects an aspect of social reality. An act of automatic stereotyping can be poor from an epistemic perspective even if the stereotype that is activated reflects reality. (shrink)

What is Heidegger talking about when he says that being conceals itself? This is the first study to systematically address that question. Katherine Withy analyses texts from across Heidegger's philosophical career and sorts the various phenomena of concealing and concealment that Heideggerdiscusses into a highly-structured taxonomy. The taxonomy clarifies the relationships and differences between such phenomena as lethe, the nothing, earth, excess, the backgrounding of the world, and un-truth, as well as speaking falsely, talking idly, secrets, mysteries, seeming, andinauthentic (...) discovering. But in relating and differentiating these phenomena, the taxonomy shows that none of them is the self-concealing of being.Having established what the self-concealing of being is not, Withy establishes what it is. She argues that being conceals itself in that it shows up to us as lacking the sorts of contrast cases that render entities determinate and intelligible. This novel and powerful interpretation of theself-concealing of being explains why the secondary literature to date has discussed it in vague and metaphorical terms, as well as why Heidegger tends to collapse being's self-concealing into the concealment of lethe. Withy's interpretation is both a clarification of and a corrective to Heidegger'snotoriously difficult and sometimes misleading discussions of being as self-concealing. (shrink)

Research on value congruence rests on the assumption that values denote desirable behaviors and ideals that employees and organizations strive to approach. In the present study, we develop and test the argument that a more complete understanding of value congruence can be achieved by considering a second type of congruence based on employees’ and organizations’ counter-ideal values. We examined this proposition in a time-lagged study of 672 employees from various occupational and organizational backgrounds. We used difference scores as well as (...) polynomial regression and response surface analyses to test our hypotheses. Consistent with our hypotheses, results reveal that counter-ideal value congruence has unique relations to employees’ trust in the organization that go beyond the effects of ideal value congruence. We discuss theoretical and practical implications of this expanded perspective on value congruence. (shrink)

There are moments when things suddenly seem strange - objects in the world lose their meaning, we feel like strangers to ourselves, or human existence itself strikes us as bizarre and unintelligible. Through a detailed philosophical investigation of Heidegger's concept of uncanniness (Unheimlichkeit), Katherine Withy explores what such experiences reveal about us. She argues that while others (such as Freud, in his seminal psychoanalytic essay, 'The Uncanny') take uncanniness to be an affective quality of strangeness or eeriness, Heidegger uses (...) the concept to go beyond feeling uncanny to reach the ground of this feeling in our being uncanny. -/- "Heidegger on Being Uncanny" answers those who wonder whether human existence is fundamentally strange to itself by showing that we can be what we are only if we do not fully understand what it is to be us. This fundamental finitude in our self-understanding is our uncanniness. In this first dedicated interpretation of Heidegger's uncanniness, Withy tracks this concept from his early analyses of angst through his later interpretations of the choral ode from Sophocles's Antigone. Her interpretation uncovers a novel and robust continuity in Heidegger's thought and in his vision of the human being as uncanny, and it points the way toward what it is to live well as an uncanny human being.

Gatekeeping, or determining membership of your group, is crucial to science: the moniker ‘scientific’ is a stamp of epistemic quality or even authority. But gatekeeping in science is fraught with dangers. Gatekeepers must exclude bad science, science fraud and pseudoscience, while including the disagreeing viewpoints on which science thrives. This is a difficult tightrope, not least because gatekeeping is a human matter and can be influenced by biases such as groupthink. After spelling out these general tensions around gatekeeping in science, (...) we shed light on them with a case study from psychology. This concerns whether academic psychologists rightly or wrongly classify the applied-psychology framework of NLP (‘neuro-linguistic programming’) as unscientific and even pseudoscientific. This example of gatekeeping is particularly instructive because both the NLP community and the psychology community, we argue, make legitimate but also illegitimate moves. This case gives rise to several general insights about gatekeeping in science more generally. (shrink)

Findings from the cognitive sciences suggest that the cognitive mechanisms responsible for some memory errors are adaptive, bringing benefits to the organism. In this paper we argue that the same cognitive mechanisms also bring a suite of significant epistemic benefits, increasing the chance of an agent obtaining epistemic goods like true belief and knowledge. This result provides a significant challenge to the folk conception of memory beliefs that are false, according to which they are a sign of cognitive frailty, indicating (...) that a person is less reliable than others or their former self. Evidence of memory errors can undermine a person’s view of themselves as a competent epistemic agent, but we show that false memory beliefs can be the result of the ordinary operation of cognitive mechanisms found across the species, which bring substantial epistemic benefits. This challenge to the folk conception is not adequately captured by existing epistemological theories. However, it can be captured by the notion of epistemic innocence, which has previously been deployed to highlight how beliefs which have epistemic costs can also bring significant epistemic benefits. We therefore argue that the notion of epistemic innocence should be expanded so that it applies not just to beliefs but also to cognitive mechanisms. (shrink)

From 1908 to 1922, William Beebe, the curator of birds at the Bronx Zoo, tried unsuccessfully to bring tropical birds known as hoatzin to the zoological park in the Bronx run by the New York Zoological Society. Beebe was committed to bringing hoatzin to the zoo because he thought they could reveal scientific truths about ecology and evolution to him and the visiting public. While contemporary scholarship about zoo science in the United States has focused on how environmental conservation shaped (...) the scientific practices of zoos at the turn to the 20th century, Beebe's efforts to bring hoatzin to the Bronx shows that evolutionary theory and ecology were central issues at the institution. Beebe wanted to use zoo displays to conduct research into the relationships between organisms and environments in order to investigate how certain animal behaviors, such as flight, developed. Beebe's employers, Madison Grant and Henry Osborn, were less interested in Beebe's experimentation with zoo exhibits, and more invested in using the zoo as a place to disseminate evolutionary ideas they already understood as scientific truths about heredity, racial hierarchies, and eugenics. Whereas Beebe saw his scientific practice as dependent on ecological connections, Grant and Osborn stressed a narrative of purity and separation (of species and race) that governed the conservation projects and scientific focus of the Zoological Society, as well as the presentation of animals on zoo grounds. Ultimately, Grant and Osborn's evolutionary concerns and their vision of a hierarchical natural world dictated the scientific direction of the Bronx Zoo in a way that prevented the institution from becoming a site for ecological research.

The American Society for Bioethics and Humanities has created a quality attestation process for clinical ethics consultants; the pilot phase of reviewing portfolios has begun. One aspect of the QA process which is particularly challenging is assessing the interpersonal skills of individual clinical ethics consultants. We propose that using case simulation to evaluate clinical ethics consultants is an approach that can meet this need provided clear standards for assessment are identified. To this end, we developed the Assessing Clinical Ethics Skills (...) tool, which identifies and specifies specific behaviors that a clinical ethics consultant should demonstrate in an ethics case simulation. The aim is for the clinical ethics consultant or student to use a videotaped case simulation, along with the ACES tool scored by a trained rater, to demonstrate their competence as part of their QA portfolio. The development and piloting of the tool is described. (shrink)

B a c k g r o u n d. Deng Xiaoping is considered the main architect of socialist reforms and the founder of China's modernization theory. He mastered and developed the socialist system, trying to adjust it to the national conditions of China. Deng Xiaoping believed that it was by following the course of "socialism with Chinese characteristics" that China would transform from a poor country into a highly developed one. The article provides a theoretical reconstruction of the main (...) content of Deng Xiaoping's concept of "socialism with Chinese characteristics." The main philosophical and socio-political aspects of the concept of building socialism with Chinese characteristics are presented in a systematic form in the context of the foundations of Chineseization of Marxism. M e t h o d s. In the article, a historical-logical approach was used to reveal the specified research topic, which allowed us to determine the socio-political prerequisites for the emergence of Chineseized Marxism. An interdisciplinary approach made it possible to carry out a theoretical analysis of social, economic, and political changes in modern China, which were caused by the proposed theory of Deng Xiaoping's "socialism with Chinese characteristics". Systemic, structural-functional, and constructivist methods, as well as methods of synthesis and generalization, were also applied. R e s u l t s. Because of the above, the purpose of this study was to carry out a theoretical reconstruction of Deng Xiaoping's theory of building "socialism with Chinese characteristics" and to find out how his ideas influenced the development of modern China after the completion of the "Great Leap Forward" and the "Cultural Revolution" of Mao Zedong. The key features of Deng Xiaoping's proposed theory of "socialism with Chinese characteristics" were established, including the idea of democratization of society and implementation of the legal basis of state functioning; the beginning of a new period of "reforms and openness"; determining the course for socialist modernization; following Marxism-Leninism and the ideas of Mao Zedong. C o n c l u s i o n s. In conclusion, it can be noted that the main feature of Deng Xiaoping's ideas was that they were inextricably linked with the national and cultural traditions of Chinese civilization, starting from Confucianism and the gradual synthesis with Marxist ideology. Evaluating the theory of Deng Xiaoping, it can be defined as a relatively complete scientific system that covers the fields of philosophy, political economy, and scientific socialism, it contains the doctrine of socialist ideology, and the doctrine of the essence and ways of socialist development, theories of the reform of socialist political and economic systems, the theory of building a socialist country.

The COVID-19 pandemic laid bare systemic inequities shaped by social determinants of health (SDoH). Public health agencies, legislators, health systems, and community organizations took notice, and there is currently unprecedented interest in identifying and implementing programs to address SDoH. This special issue focuses on the role of medical-legal partnerships (MLPs) in addressing SDoH and racial and social inequities, as well as the need to support these efforts with evidence-based research, data, and meaningful partnerships and funding.

ABSTRACTDiagnostic self‐testing devices are being developed for many illnesses, chronic diseases and infections. These will be used in hospitals, at point‐of‐care facilities and at home. Designed to allow earlier detection of diseases, self‐testing diagnostic devices may improve disease prevention, slow the progression of disease and facilitate better treatment outcomes. These devices have the potential to benefit both the individual and society by enabling individuals to take a more proactive role in the maintenance of their health and by helping society improve (...) health and reduce health costs. However, the full implications of future home‐based diagnostic technology for individuals and society remain unclear due to their novelty.We argue that the development of diagnostic tools, especially for home use, will heighten a number of ethical challenges. This paper will explore some of the ethical implications of home‐based self‐testing diagnostic devices for the autonomous and relational dimensions of the person. This will be facilitated by examining the impact of diagnostic devices for individual autonomy, for the delivery of accurate diagnosis and for the personal significance of the information for the user. The latter will be examined using Charles Taylor's view of personhood and his emphasis on human agency and interpretation.While the ethical issues are not necessarily new, the development of home‐based self‐testing diagnostic devices will make issues regarding autonomy, accuracy of information and personal significance more and more demanding. This will be the case particularly when an individual's autonomous choices come into conflict with the person's relational responsibilities. (shrink)

Du Châtelet’s 1740 text Foundations of Physics tackles three of the major foundational issues facing natural philosophy in the early eighteenth century: the problem of bodies, the problem of force, and the question of appropriate methodology. This paper offers an introduction to Du Châtelet’s philosophy of science, as expressed in her Foundations of Physics, primarily through the lens of the problem of bodies.

This article draws from Hannah Arendt's theory of “inter-est” to formulate a model of coalition discourse that can coarticulate difference and commonality and approach them as mutually nourishing conditions rather than as polarities. By disrupting the normative fantasies of unified, a priori subjectivity and universal truth, interest-based discourse facilitates political interactions that neither rely on sameness nor reify difference to the exclusion of connection.

Katherine Hawley explores and compares three theories of persistence -- endurance, perdurance, and stage theories - investigating the ways in which they attempt to account for the world around us. Having provided valuable clarification of its two main rivals, she concludes by advocating stage theory.

Symmetry considerations dominate modern fundamental physics, both in quantum theory and in relativity. Philosophers are now beginning to devote increasing attention to such issues as the significance of gauge symmetry, quantum particle identity in the light of permutation symmetry, how to make sense of parity violation, the role of symmetry breaking, the empirical status of symmetry principles, and so forth. These issues relate directly to traditional problems in the philosophy of science, including the status of the laws of nature, the (...) relationships between mathematics, physical theory, and the world, and the extent to which mathematics suggests new physics.This entry begins with a brief description of the historical roots and emergence of the concept of symmetry that is at work in modern science. It then turns to the application of this concept to physics, distinguishing between two different uses of symmetry: symmetry principles versus symmetry arguments. It mentions the different varieties of physical symmetries, outlining the ways in which they were introduced into physics. Then, stepping back from the details of the various symmetries, it makes some remarks of a general nature concerning the status and significance of symmetries in physics. (shrink)
