What, if anything, would be wrong with replacing the light postulate in Einstein’s 1905 formulation of special relativity with a ‘sound postulate’, stating that the speed of sound is independent of the speed of the source? After reviewing the historical reasons underlying the particular focus on light in the special theory, we consider the circumstances under which such a theory of ‘sonic relativity’ would be justified on empirical grounds. We then consider the philosophical upshots of ‘sonic relativity’ for four contemporary (...) areas of investigation in the philosophy of spacetime: global versus subsystem symmetries, dynamical versus geometrical approaches to spacetime, the possibility of a preferred frame in theories of quantum gravity, and spacetime functionalism.

We explore the significance of physical theories set in Euclidean spacetimes. In particular, we explore the use of these theories in contemporary physics at large, and the sense in which there can be a notion of temporal evolution in these theories. Having achieved these tasks, we proceed to reflect on the lessons that one can take from such theories for Knox’s ‘inertial frame’ version of spacetime functionalism, which seems to issue incorrect verdicts in the case of theories with Euclidean metrical (...) structure.

In support of their contention that it is the absence of a subsisting medium that imbues the speed of light with fundamentality, Bryan Cheng and James Read discuss certain “fishbowl universes” in which physical influences evolve, not at the speed of light, but that of sound. The Lorentz transformation simulated in these sonic universes, which the authors cite from the literature of analogue gravity, is not that of Einstein, for whom an aether was “superfluous”, but that of the (...) earlier relativity of Lorentz and Poincaré, which did suppose such a medium. The authors’ intention is not to argue analogically, but simply to contrast the situation of light with that of sound. However, I argue that these universes are too successful as analogues to support the authors’ case. By reducing Lorentzian relativity to its bare essentials, they provide a compelling demonstration of the viability and explanatory strengths of the earlier theory. They show how a thoroughly wave-theoretic treatment of the elementary particles would explain why all aspects of matter transform in like manner, thereby avoiding a difficulty that was a significant reason for the demise of Lorentzian relativity after 1905. Importantly, these sonic universes suggest a unifying explanation, not only of the Lorentz transformation and de Broglie wave, but of the principle of relativity, which was merely postulated, rather than explained, by Einstein in 1905.

This study aims to provide a coherent new interpretation of the notorious anti-hedonism of Speusippus, Plato’s nephew and the second scholarch of the Academy, by reconsidering all the relevant sources concerning his attitude toward pleasure—sources that seem to be in tension or even incompatible with each other. By reassessing Speusippus’ anti-hedonism and Aristotle’s response, it also sheds new light on the Academic debate over pleasure in which he and Aristotle participated: This debate is not merely concerned with the truth and (...) credibility of the arguments for or against hedonism; there are also notable differences among the participants in their understanding of the practical significance of evaluating hedonic experiences. This new interpretation allows us to better understand Aristotle’s selective representation of the intra-school debate and some neglected features of his responses to different interlocutors.

Montague and Kaplan began a revolution in semantics, which promised to explain how a univocal expression could make distinct truth-conditional contributions in its various occurrences. The idea was to treat context as a parameter at which a sentence is semantically evaluated. But the revolution has stalled. One salient problem comes from recurring demonstratives: "He is tall and he is not tall". For the sentence to be true at a context, each occurrence of the demonstrative must make a different truth-conditional contribution. (...) But this difference cannot be accounted for by standard parameter sensitivity. Semanticists, consoled by the thought that this ambiguity would ultimately be needed anyhow to explain anaphora, have been too content to posit massive ambiguities in demonstrative pronouns. This article aims to revived the parameter revolution by showing how to treat demonstrative pronouns as univocal while providing an account of anaphora that doesn't end up re-introducing the ambiguity.

This is a revised and enlarged version of Bryan Magee's widely praised study of Schopenhauer, the most comprehensive book on this great philosopher. It contains a brief biography of Schopenhauer, a systematic exposition of his thought, and a critical discussion of the problems to which it gives rise and of its influence on a wide range of thinkers and artists. For this new edition Magee has added three new chapters and made many minor revisions and corrections throughout. This new (...) edition will consolidate the book's standing as the definitive study of Schopenhauer. (shrink)

Those of us who take skepticism seriously typically have two relevant beliefs: (a) it’s plausible (even if false) that in order to know that I have hands I have to be able to epistemically neutralize, to some significant degree, some skeptical hypotheses, such as the brain-in-a-vat (BIV) one; and (b) it’s also plausible (even if false) that I can’t so neutralize those hypotheses. There is no reason for us to also think (c) that the BIV hypothesis, for instance, is plausible (...) or probably true. In order to take skepticism seriously it’s sufficient to hold (a) and (b); one need not hold (c). Indeed, philosophers who accept (a) and (b) never endorse (c). Show me a philosopher who suspects that he is a brain in a vat and I’ll show you someone who is deranged! That’s one thing that bothers undergraduates in philosophy. They object: why on earth do some philosophers take the BIV hypothesis to pose any threat at all to our beliefs given that those very same philosophers think that there’s no real chance that the BIV hypothesis is true? Sure, the BIV hypothesis is formally inconsistent with my belief that I have hands, so if the former is true then my belief is false. But so what? Why should that bare inconsistency matter so much? Is this strange attitude amongst philosophers the result of some logic fetish infecting the philosophical community? It is sometimes said that the skeptical hypotheses are not only inconsistent with our beliefs but are explanatory of our experiences, which is supposed to make them more of a threat. But students aren’t fooled: although the skeptical hypotheses may attempt to explain why our experience is as it is, it’s the kind of attempt appropriate for science fiction movies that are all special effects and virtually no plot. No one with any sense of reality will take the evil demon hypothesis to be even tenuously explanatory. (shrink)

The Greek word eoikos can be translated in various ways. It can be used to describe similarity, plausibility or even suitability. This book explores the philosophical exploitation of its multiple meanings by three philosophers, Xenophanes, Parmenides and Plato. It offers new interpretations of the way that each employs the term to describe the status of their philosophy, tracing the development of this philosophical use of eoikos from the fallibilism of Xenophanes through the deceptive cosmology of Parmenides to Plato's Timaeus. The (...) central premise of the book is that, in reflecting on the eoikos status of their accounts, Xenophanes, Parmenides and Plato are manipulating the contexts and connotations of the term as it has been used by their predecessors. By focusing on this continuity in the development of the philosophical use of eoikos, the book serves to enhance our understanding of the epistemology and methodology of Xenophanes, Parmenides and Plato's Timaeus.

In the language of second-order logic, first- and second-order variables are distinguished syntactically and cannot be grammatically substituted. According to a prominent argument for the deployment of these languages, these substitution failures are necessary to block the derivation of paradoxes that result from attempts to generalize over predicate interpretations. I first examine previous approaches which interpret second-order sentences using expressions of natural language and argue that these approaches undermine these syntactic restrictions. I then examine Williamson’s primitivist approach according to which (...) second-order sentences are not offered readings in a previously understood language. I argue that the syntactic restrictions alone do not block the derivation of the paradox, unless they are backed by a principled reason that the language cannot be expanded to allow the grammatical substitution of first- and second- order variables. I argue that there is neither a syntactic nor a semantic principle that prohibits such an expansion. (shrink)

The principle of compositionality requires that the meaning of a complex expression remains the same after substitution of synonymous expressions. Alleged counterexamples to compositionality seem to force a theoretical choice: either apparent synonyms are not synonyms or synonyms do not syntactically occur where they appear to occur. Some theorists have instead looked to Frege’s doctrine of “reference shift” according to which the meaning of an expression is sensitive to its linguistic context. This doctrine is alleged to retain the relevant claims (...) about synonymy and substitution while respecting the compositionality principle. Thus, Salmon (Philos Rev 115(4):415, 2006) and Glanzberg and King (Philosophers’ Imprint 20(2):1–29, 2020) offer occurrence-based accounts of variable binding, and Pagin and Westerståhl (Linguist Philos 33(5):381–415, 2010c) argue that an occurrence-based semantics delivers a compositional account of quotation. Our thesis is this: the occurrence-based strategies resolve the apparent failures of substitutivity in the same general way as the standard expression-based semantics do. So it is a myth that a Frege-inspired occurrence-based semantics affords a genuine alternative strategy. (shrink)

Aristotle’s theory of human happiness in the Nicomachean Ethics explicitly depends on the claim that contemplation (theôria) is peculiar to human beings, whether it is our function or only part of it. But there is a notorious problem: Aristotle says that divine beings also contemplate. Various solutions have been proposed, but each has difficulties. Drawing on an analysis of what divine contemplation involves according to Aristotle, I identify an assumption common to all of these proposals and argue for rejecting it. (...) This allows a straightforward solution to the problem and there is evidence that Aristotle would have adopted it. (shrink)

After a period of inactivity, interest in explanationism as a thesis about the nature of epistemic justification has been renewed. Poston and McCain have both recently offered versions of explanationist evidentialism. In this paper, we pose two objections to explanationist evidentialism. First, explanationist evidentialism fails to state a sufficient condition for justification. Second, explanationist evidentialism implies a vicious regress.

:Since the advent of recombinant DNA technology, expectations about the potential for altering genes and controlling our biology at the fundamental level have been sky high. These expectations have gone largely unfulfilled. But though the dream of being able to control our biology is still far off, gene editing research has made enormous strides toward potential clinical use. This paper argues that when it comes to determining permissible uses of gene editing in one important medical context—germline intervention in reproductive medicine—issues (...) about enhancement and eugenics are, for the foreseeable future, a red herring. Current translational goals for gene editing research involve a different kind of editing than would be required to achieve manipulation of complex traits such as intelligence, and there are more pressing questions that need attention if clinical use of gene editing in reproductive medicine ever becomes a possibility.

This practical guide helps us identify the wrong beliefs about God we received from our families of origin and replace them with truth so we can embrace the abundant Christian life we long for.

In a brilliant and explosively controversial work, the author attacks modern science for destroying our spiritual sense of self. What is the role of science in present-day society? Should we be as dazzled as we are by the innovations, the insights, and the miraculous improvements in material life that science has wrought? Or is there a darker, more pernicious side to our scientific success? Renowned British science columnist Bryan Appleyard thoroughly explores each of these provocative topics in a book (...) that has incited the ire of the scientific community. He points out that while scientists have shaped our lives and our beliefs, they have consistently failed to explain human consciousness, the soul, or the meaning of life. From Galileo to Darwin, from Copernicus to Oppenheimer, countless scientists have proclaimed a universe in which human beings are only an accidental presence. The unwitting result is that science has cast humankind adrift, paralyzing us with fear and cutting us off from personal or religious truth. In Appleyard's view, science has done us "appalling spiritual damage." These startling conclusions have prompted strong counterattacks from the scientific establishment. Yet regardless of where one falls in the debate, Understanding the Present forces readers to re-examine society's blind faith in the benevolence of modern science.

A central dispute in understanding Frege’s philosophy concerns how the sense of a complex expression relates to the senses of its component expressions. According to one reading, the sense of a complex expression is a whole built from the senses of the component expressions. On this interpretation, Frege is an early proponent of structured propositions. A rival reading says that senses compose by functional application: the sense of a complex expression is the value of the function denoted by its functional (...) component for the arguments denoted by its remaining components. I argue that two non-negotiable Fregean theses entail that senses compose by functional application. One thesis is that referents compose by functional application. The other thesis is that an expression in an indirect context refers to its customary sense. (shrink)

The distinction between germline and somatic gene editing is fundamental to the ethics of human gene editing. Multiple conferences of scientists, ethicists, and policymakers, and multiple professional bodies, have called for moratoria on germline gene editing, and editing of human germline cells is considered to be an ethical “red line” that either never should be crossed, or should only be crossed with great caution and care. However, as research on germline gene editing has progressed, it has become clear that not (...) all germline interventions are alike, and that these differences make a significant moral difference, when it comes to ethical questions about research, regulation, clinical application, and medical justification. In this paper, I argue that, rather than lumping all germline interventions together, we should distinguish between revising, correcting, and transferring genes, and I assess the consequences of this move for the ethics of gene editing.

This book develops a comprehensive framework for ethics in the helping professions based on bioethicist Bernard Gert's theory of common morality. The prevailing model of ethics education is built upon adherence to codes of ethics applied largely through the use of decision-making trees. While a firm understanding of a professions code of ethics and all relevant laws is essential to responsible practice, this approach to teaching ethics excludes the opportunity for students to acquire a holistic, and grounded understanding of moral (...) action. The framework proposed in this text moves beyond codes of ethics, and allows students to develop a cohesive sense of ethical reasoning that both validates their moral intuition and challenges moral assumptions. The theory of a common morality uses a systematic, step-by-step approach that readers and practitioners can apply to all questions of moral action and behaviour. While there is no such thing as a single right answer to any ethical question, by following this approach practitioners can confidently eliminate the bad decisions, allowing them to feel more secure in their decision and practice.

One of the problems religious men and philosophers often face is how to convey enlightenment or wisdom to others so that sentient beings can be enlightened or awakened from dogmatic views. This problem is also the question of how truth is made known to men. The purpose of this paper is to investigate the problem of communicating truth in Ch'an Buddhism.

We tend to think that philosophical progress, to the extent that it exists, is a good thing. I agree. Even so, it has some surprising unfortunate consequences for the rationality of philosophical belief.

Design of clinical trials for germline gene editing stretches current accepted standards for human subjects research. Among the challenges involved is a set of issues concerningintergenerational monitoring—long-term follow-up study of subjects and their descendants. Because changes made at the germline would be heritable, germline gene editing could have adverse effects on individuals’ health that can be passed on to future generations. Determining whether germline gene editing is safe and effective for clinical use thus may require intergenerational monitoring. The aim of (...) this paper is to identify and argue for the significance of a set of ethical issues raised by intergenerational monitoring in future clinical trials of germline gene editing. Though long-term, multigenerational follow-up study of this kind is not without precedent, intergenerational monitoring in this context raises unique ethical challenges, challenges that go beyond existing protocols and standards for human subjects research. These challenges will need to be addressed if clinical trials of germline gene editing are ever pursued. (shrink)

This article argues that economic crises are incompatible with the realisation of non-domination in capitalist societies. The ineradicable risk that an economic crisis will occur undermines the robust security of the conditions of non-domination for all citizens, not only those who are harmed by a crisis. I begin by demonstrating that the unemployment caused by economic crises violates the egalitarian dimensions of freedom as non-domination. The lack of employment constitutes an exclusion from the social bases of self-respect, and from a (...) practice of mutual social contribution crucial to the intersubjective affirmation of one’s status. While this argument shows that republicans must be concerned about economic crises, I suggest a more powerful argument can be grounded in the republican requirement that freedom must be robust. The systemic risk of economic crisis constitutes a threat to the conditions of free citizenship that cannot be nullified using policy mechanisms. As a result, republicans appear to be faced with the choice of revising their commitments or rejecting the possibility that republican freedom can be robustly secured in capitalist societies.

How secular is contemporary society? Are pockets of sectarianism embedded in societies of developed countries? This timely book examines the interweaving of politics and religion, and of tradition and innovation in a variety of cultural settings. Eminent scholars from four continents examine here current turmoil in religious beliefs, practices, and organization--not only in the Western world, but in South America, Africa, South Asia, New Zealand, and Japan. They scrutinize evidence of religious change, decline, and revival; investigate challenges posed by new (...) religious movements; and locate religious change and conflict in the context of broader shifts in consciousness and culture. Contributors include Richard Fenn, Phillip E. Hammond, David Martin, Philip Rieff, Roland Robertson, and Mark Schibley. With its focus on the interplay of secularization, rationalism, and sectarianism, this work offers a fitting tribute to Bryan Wilson, who has made so many contributions to the sociological understanding of these phenomena.

Aristotle thinks that happiness is an activity---it consists in doing something---rather than a feeling. It is the best activity of which humans are capable and is spread out over the course of a life. But what kind of activity is it? Some of his remarks indicate that it is a single best kind of activity, intellectual contemplation. Other evidence suggests that it is an overarching activity that has various virtuous activities, ethical and intellectual, as parts. At stake are questions about (...) how we should live and the correct balance of theoretical and practical activity. Numerous interpreters have sharply disagreed about Aristotle's answers to such questions. This book offers a fundamentally new approach to determining what kind of activity Aristotle thinks happiness is, one that challenges widespread assumptions that have until now prevented a dialectically satisfactory interpretation. This approach displays the boldness and systematicity of Aristotle's practical philosophy. (shrink)

Este artigo investiga as diferentes concepções de “Sujeito” de acordo com o corpus teórico do filósofo Paul B. Preciado. As categorias analisadas são: os processos subjetivos e técnicos de sujeição social e servidão maquínica na era farmacopornográfica; o sujeito Playboy e petrosexorracial; a Multidão, seus múltiplos devires e as micropolíticas de resistência à opressão; a metamorfose dos sujeitos em agentes revolucionários e os simbiontes políticos, postulados por Preciado em seu mais recente livro publicado, Dysphoria mundi. Como Preciado articula todas estas (...) concepções, considerando ainda as linhas de fuga da submissão, isto é, o horizonte filosófico de resistência onto-epístemo-política, metamorfose e até a possível superação da dominação capitalística? Os procedimentos metodológicos foram baseados na pesquisa bibliográfica (livros, artigos e crônicas), de modo a evidenciar o contraste, as semelhanças, diferenças e interstícios entre a teoria de Preciado e as suas principais referências. Os resultados obtidos indicam uma linearidade consistente entre-categorias, os desafios em materializar as teorias revolucionárias na realidade cotidiana, bem como estratégias práticas que contribuem para a organização ontopolítica proposta por Preciado.

If you retain your belief upon learning that a large number and percentage of your recognized epistemic superiors disagree with you, then what happens to the epistemic status of your belief?

I argue that even if all those error theories are false, either (...)

To contribute to the continuing challenge of explaining how managers identify stakeholders and assess their salience, in this article, we chronicle the history, assess the impact, and evaluate the possibilities opened by Mitchell, Agle, and Wood (MAW-1997). We do so through two types of qualitative analysis, and also through utilizing a quantitative network analysis tool. The first qualitative analysis categorizes the major contributions of the most influential papers succeeding MAW-1997; the second identifies and compares the relevant issues with MAW-1997 at (...) the time of initial publication and today. We apply main path analysis, a quantitative tool, to map how this scholarly domain has evolved. These three analyses robustly depict the impact of MAW-1997 and the ensuing scholarly conversation, and they enable us to illustrate the current state and trajectory of stakeholder identification and salience scholarship. We close by discussing pressing topics related to the broader body of stakeholder theory literature. (shrink)

Ancient Greek and Roman philosophy is often characterised in terms of competitive individuals debating orally with one another in public arenas. But it also developed over its long history a sense in which philosophers might acknowledge some other particular philosopher or group of philosophers as an authority and offer to that authority explicit intellectual allegiance. This is most obvious in the development after the classical period of the philosophical 'schools' with agreed founders and, most importantly, canonical founding texts. There also (...) developed a tradition of commentary, interpretation, and discussion of texts which itself became a mode of philosophical debate. As time went on, the weight of a growing tradition of reading and appealing to a certain corpus of foundational texts began to shape how later antiquity viewed its philosophical past and also how philosophical debate and inquiry was conducted. In this book leading scholars explore aspects of these important developments. (shrink)

In this paper I begin by suggesting that Immanuel Kant’s argument for the impermissibility of treating others with contempt seems to be subject to a paradox very similar to the well known paradox of forgiveness first described by Aurel Kolnai. Specifically, either the object of the judgment of contempt is not really contemptible, in which case the prohibition on treating him with contempt is superfluous, or else the person truly is contemptible, in which case the prohibition seems unjustifiable, reducing to (...) a mere condonation of wrongdoing. My goal in the paper is to show that this paradox is only apparent. Making use of the philosophy of phrases that Jean-François Lyotard develops in The Differend—emphasizing especially the ideas of phrase-event, presentation, situation, addressor, and addressee—I argue that the Kantian prohibition on treating others with contempt is rationally defensible, even in cases in which we believe the object of the judgment of contempt truly is contemptible.
