In this paper, I make two claims: an opera’s music, both vocal and instrumental, is part of the ontology of its fictional world, and song constitutes the normative mode of communication and expression in the fictional world. I refute Carolyn Abbate’s influential arguments that both of these claims are untrue. Abbate’s contention that opera characters do not have epistemic access to the music is based on false premises and gives rise to serious interpretive problems. My account of operatic metaphysics refines (...) and extends the work of Edward T. Cone and Peter Kivy. Where I diverge from their respective accounts is in my contention that the orchestral music typically does not have a fictional author. Often its real author is the only agent to which it may be logically attributed. (shrink)

Much neuroethics literature concludes with a set of normative recommendations. While these recommendations can be a helpful way of summarizing a proposal for a future direction, some have recently argued that ethics scholarship has devoted insufficient attention to considerations of audience and real-world applications. To date, however, while scholars have conducted topic analyses of neuroethics literature, to our knowledge no study has evaluated who neuroethics scholarship addresses and what it recommends. The objective of the present study therefore was to provide (...) a preliminary characterization of recommendations offered in neuroethics scholarship and an assessment of their target audiences. Rather than attempting to demarcate what constitutes “neuroethics scholarship,” we analyzed text that authors’ had self-identified as being neuroethics-related: abstracts presented at the International Neuroethics Society (INS) annual meetings and published as top abstracts in AJOB Neuroscience in the last decade (2011–2020). We found that a majority of abstracts utilized conceptual methods (62.2%) and provided conceptual recommendations (68%). Roughly 77% of all abstracts did not explicitly address a target audience, yet nearly all of these were implicitly directed at other scholars. The remainder specified a target audience of scholars (12.2%), regulators (6.7%), healthcare providers (6.7%) and industry (2.6%). Only a subset of abstracts provided practical or policy recommendations (19.7%). Of those, the majority (61.5%) did not specify a target audience. Among the subset with actionable recommendations, a clarification of target audience may help increase the impact. (shrink)

Philosophers and scientists both ask questions about what the world is like. How do these fields interact with one another? How should they? Naturalism Beyond the Limits of Science investigates an approach to these questions called methodological naturalism. According to methodological naturalism, when coming up with theories about what the world is like, philosophers should, whenever possible, make use of the same methodology that is deployed by scientists. Although many contemporary philosophers have implicit commitments that lead straightforwardly to methodological naturalism, (...) few have a clear understanding of how widespread and disruptive methodological naturalism promises to be for the field. By way of a series of case studies involving laws of nature, composition, time and modality, and drawing on historical and contemporary scientific developments including the discovery of the neutrino, the introduction of dark energy, and the advent of relativity theory, this book demonstrates the ways in which scientists rely on extra-empirical reasoning and how that very same extra-empirical reasoning can yield surprising results when applied to philosophical debates. Along the way, Nina Emery's investigation illuminates the complex relationship between philosophy and the sciences, and makes the case that philosophers and scientists alike would benefit from a greater understanding of the connections between the two fields.

Vibrant Death links philosophy and poetry-based, corpo-affectively grounded knowledge seeking. It offers a radically new materialist theory of death, critically moving the philosophical argument beyond Christian and secular-mechanistic understandings. The book's ethico-political figuration of vibrant death is shaped through a pluriversal conversation between Deleuzean philosophy, neo-vitalist materialism and the spiritual materialism of decolonial, queerfeminist poet and scholar Gloria Anzaldua. The book's posthuman deexceptionalizing of human death unfurls together with a collection of poetry, and autobiographical stories. They are analysed through the (...) lens of a posthuman, queerfeminist revision of the method of autophenomenography (phenomenological analysis of autobiographical material). Nina Lykke explores the speaking position of a mourning, queerfeminine "I", who contemplates the relationship with her dead beloved lesbian life partner. She reflects on her enactment of processes of co-becoming with the phenomenal and material traces of the deceased body, and the new assemblages with which it has merged through death's material metamorphoses: becoming-ashes through cremation, and becoming-mixed-with-algae-sand when the ashes were scattered across a seabed made of fiftyfive million-year-old, fossilized algae. It is argued that the mourning "I"'s intimate bodily empathizing (theorized as symphysizing) with her deceased, queermasculine beloved life partner facilitates the processes of vitalist-material and spiritual-material co-becoming, and the rethinking of death from a new and different perspective than that of the sovereign, philosophical subject.

BackgroundIt has been argued that ethics review committees—e.g., Research Ethics Committees, Institutional Review Boards, etc.— have weaknesses in reviewing big data and artificial intelligence research. For instance, they may, due to the novelty of the area, lack the relevant expertise for judging collective risks and benefits of such research, or they may exempt it from review in instances involving de-identified data.Main bodyFocusing on the example of medical research databases we highlight here ethical issues around de-identified data sharing which motivate the (...) need for review where oversight by ethics committees is weak. Though some argue for ethics committee reform to overcome these weaknesses, it is unclear whether or when that will happen. Hence, we argue that ethical review can be done by data access committees, since they have de facto purview of big data and artificial intelligence projects, relevant technical expertise and governance knowledge, and already take on some functions of ethical review. That said, like ethics committees, they may have functional weaknesses in their review capabilities. To strengthen that function, data access committees must think clearly about the kinds of ethical expertise, both professional and lay, that they draw upon to support their work.ConclusionData access committees can undertake ethical review of medical research databases provided they enhance that review function through professional and lay ethical expertise.

Introduction:The effects of specific suggestions are usually studied by measuring parameters that are directly addressed by these suggestions. We recently proposed the use of a uniform, unrelated, and objective measure like maximal muscle strength that allows comparison of suggestions to avoid nocebo effects and thus to improve communication. Since reduced breathing strength might impair respiration and increase the risk of post-operative pulmonary complications, the aim of the present study was to evaluate the effects of the suggestions on respiratory muscle power. (...) Both the identification and neutralization of negative suggestions in the clinical context and stimulating suggestions could improve breathing force, a predictor of physical fitness and convalescence.MethodsIn 50 healthy, adult volunteers, respiratory muscle strength was measured by maximal inspiratory and expiratory pressures, as well as by maximal inspiratory and expiratory flows. Baseline was compared to values after application of eleven suggestions, five out of clinical context, including memory of negative or positive past, risk information for informed consent, and a non-verbal suggestion. Six stimulating suggestions included self-affirmation, empowering words, a heroic mirror image, and an imagination.ResultsAll suggestions showed an impact on respiratory muscle strength, indicating placebo and nocebo effects. No single parameter could represent the breathing force in its complexity, however, trends and different specific aspects of it were measured. The strongest reaction was observed with the recall of a previous negative situation resulting in a reduction in expiratory flow to 96.1% of baseline. After risk information, a decrease was observed in three of the parameters, with the highest extend in expiratory pressure by 4.4%. This nocebo effect was neutralized by adding positive aspects to the risk information. Every intended strengthening suggestion resulted in statistically significant increases of at least one parameter, with changes of up to 10%, indicating placebo effects. Here, expiration was more affected than inspiration. Sex was the only influencing factor reaching statistical significance, with stronger reactions in women.ConclusionRespiratory muscle strength proved to be sensitive to suggestions with clinical context, as well as suggestions intended for stimulation. With this objective measurement, evaluation, and comparison of different suggestions is possible to help avoid nocebo effects. The demonstrated effect of supporting suggestions can be followed up and used in clinical practice. (shrink)

In this groundbreaking study, Nina Gurianova identifies the early Russian avant-garde as a distinctive movement in its own right and not a preliminary stage to the Constructivism of the 1920s. Gurianova identifies what she terms an “aesthetics of anarchy”—art-making without rules—that greatly influenced early twentieth-century modernists. Setting the early Russian avant-garde movement firmly within a broader European context, Gurianova draws on a wealth of primary and archival sources by individual writers and artists, Russian theorists, theorizing artists, and German philosophers. (...) Unlike the post-revolutionary avant-garde, which sought to describe the position of the artist in the new social hierarchy, the early Russian avant-garde struggled to overcome the boundaries defining art and to bridge the traditional gap between artist and audience. As it explores the aesthetics embraced by the movement, the book shows how artists transformed literary, theatrical, and performance practices, eroding the traditional boundaries of the visual arts and challenging the conventions of their day.

Temporal ersatzism is the view that past entities exist, but are not concrete. The view is analogous to modal ersatzism, according to which merely possible worlds exist, but are not concrete. The goal of this paper is to give the reader a sense of the scope of available temporal ersatzist views, the ways in which the analogy with modal ersatzism may be helpful in characterizing and defending those views, and the sorts of considerations that are relevant when evaluating particular versions (...) of temporal ersatzism.

There is a widespread notion, both within the sciences and among the general public, that mental deterioration can rob individuals of their identity. Yet there have been no systematic investigations of what types of cognitive damage lead people to appear to no longer be themselves. We measured perceived identity change in patients with three kinds of neurodegenerative disease: frontotemporal dementia, Alzheimer’s disease, and amyotrophic lateral sclerosis. Structural equation models revealed that injury to the moral faculty plays the primary role in (...) identity discontinuity. Other cognitive deficits, including amnesia, have no measurable impact on identity persistence. Accordingly, frontotemporal dementia has the greatest effect on perceived identity, and amyotrophic lateral sclerosis has the least. We further demonstrated that perceived identity change fully mediates the impact of neurodegenerative disease on relationship deterioration between patient and caregiver. Our results mark a departure from theories that ground personal identity in memory, distinctiveness, dispositional emotion, or global mental function. (shrink)

This article takes Viviana Zelizer’s (1985) Pricing the Priceless Child to the new millennium. Zelizer documented the transformation between the 19th and 20th century from an “economically useful” to an “emotionally priceless” child. She observed that by the 1930s, American children were practically economically worthless but invested with significant emotional value. What has happened to this emotionally priceless child at the dawn of the new millennium? Has there been a new transformation in the social value of children, and, if so, (...) what might have such a transformation entailed? To address these questions, we examine overtime trends that point to increasing devotion of resources and time to children’s education, a key input in the exceedingly influential human capital theory, which connects investment into children’s human capital with their future market value. Therefore, we argue that the priceless child 2.0 is a useful-to-be human capital investment child. We use four empirical examples of overtime growth in children’s human capital investment: (a) enrollments in early childhood education, (b) federal spending on early education, (c) federal spending on K-12 programs, and (d) parental spending on child care, education and extracurricular activities. In the conclusion, we discuss some potential consequences and concerns about raising children as human capital investment. (shrink)

In a recent paper, Guy Kahane asks whether God’s existence is something we should want to be true. Expanding on some cryptic remarks from Thomas Nagel, Kahane’s informative and wide-ranging piece eventually addresses whether personal anti-theism is justified, where personal anti-theism is the view that God’s existence would make things worse overall for oneself. In what follows, I develop, defend, but ultimately reject the Meaningful Life Argument, according to which if God’s existence precludes the realization of certain goods that seem (...) to an agent to constitute a meaningful life, it is rational for an agent both to believe that personal anti-theism is true and to prefer that God not exist.

A series of recent arguments purport to show that most counterfactuals of the form if A had happened then C would have happened are not true. These arguments pose a challenge to those of us who think that counterfactual discourse is a useful part of ordinary conversation, of philosophical reasoning, and of scientific inquiry. Either we find a way to revise the semantics for counterfactuals in order to avoid these arguments, or we find a way to ensure that the relevant (...) counterfactuals, while not true, are still assertible. I argue that regardless of which of these two strategies we choose, the natural ways of implementing these strategies all share a surprising consequence: they commit us to a particular metaphysical view about chance.

Pro-theism is the view that God’s existence would be good in that God’s existence increases the value of a world. Anti-theism is the view that God’s existence would decrease the value of a world. We develop and defend the morally good agent argument for pro-theism. The basic idea is that morally good agents tend to add value to states of affairs, and God, moral agent par excellence is no exception. Thus, we argue that the existence of God would be, on (...) balance, a good thing and therefore something that one can rationally desire to be true. (shrink)

Reshaping ethnography: contemporary postpositivist possibilitiesFollowing Leinginger's introduction of ethnography into the field of nursing research, numerous descriptive and interpretive studies of health care beliefs and practices have been conducted. The resultant data have been translated into recommendations relative to the areas of nursing education, administration and clinical practice in an effort to ensure that the identified cultural needs are recognized and met. In this paper die discourses that inform such work are explored. Its practices and emergent dilemmas are reassessed in (...) die light of an emerging body of work that challenges its foundational assumptions. Linked under die umbrella of ‘postpositivist ethnography’, such work recognizes the research area as a social and political field of which the researcher is an integral part. Hence, as an informed subject, die researcher, like the informants, is seen to be implicated in the generation of data. She, or he, is not charged with occupying die opposing roles of objective researcher and subjective participant, nor with reporting ‘the truth’ as told by informants. This emergent tradition is not without its dilemmas and of particular concern is the issue of authority; that is, whose voice constructs the text? As nursing academics grapple with questions regarding die nature of die knowledge that informs their discipline, it is imperative that they critique potentially fruitful research practices before they appropriate them. Failure to do so may lead diem to unwittingly generate knowledge that is inimical to their particular quest. The lsquo;new edinographyrsquo; discussed in this paper, offers academics and odiers interested in the generation of knowledge, not only a mediodology that invites the possibility of opening up previously hidden areas of practice, but one that actively involves die researcher in challenging her taken‐for‐granted assumptions.

I argue against the common and influential view that non-trivial chances arise only when the fundamental laws are indeterministic. The problem with this view, I claim, is not that it conflicts with some antecedently plausible metaphysics of chance or that it fails to capture our everyday use of ‘chance’ and related terms, but rather that it is unstable. Any reason for adopting the position that non-trivial chances arise only when the fundamental laws are indeterministic is also a reason for adopting (...) a much stronger, and far less attractive, position. I suggest an alternative account, according to which chances are probabilities that play a certain explanatory role: they are probabilities that explain associated frequencies. 1 Introduction2 A Paradigm Case3 The Incompatibilist’s Criterion4 Against the Incompatibilist’s Criterion5 The Explanatory Criterion6 Conclusion.

The concept of intersectionality is on its way to becoming a new paradigm in gender studies. In its current version, it denominates reciprocities between gender, race and class. However, it also allows for the integration of other socially defined categories, such as sexuality, nationality or age. On the other hand, it is widely left unclear as to which level these reciprocal effects apply: the level of social structures, the level of constructions of identity or the level of symbolic representations. This (...) article advocates an intersectional multi-level analysis which takes into account reciprocal effects between the various levels. This approach includes an analytical grasp of and methodical reflection on these reciprocal effects as well as making them empirically accessible. (shrink)

A long tradition of psychological research has explored the distinction between characteristics that are part of the self and those that lie outside of it. Recently, a surge of research has begun examining a further distinction. Even among characteristics that are internal to the self, people pick out a subset as belonging to the true self. These factors are judged as making people who they really are, deep down. In this paper, we introduce the concept of the true self and (...) identify features that distinguish people’s understanding of the true self from their understanding of the self more generally. In particular, we consider recent findings that the true self is perceived as positive and moral, and that this tendency is actor-observer invariant and cross-culturally stable. We then explore possible explanations for these findings and discuss their implications for a variety of issues in psychology. (shrink)

Actualism is the view that only actually existing things exist. Presentism is the view that only presently existing things exist. In this paper, I argue that being an actualist without also being a presentist is not as easy as many philosophers seem to think. A common objection to presentism is that there is an unavoidable conflict between presentism and relativity theory. But actualists who do not wish to be presentists cannot point to this relativity objection alone to support their position. (...) Unless they have some antecedent reason for thinking that actualism is more plausible than presentism, anyone who is moved by the relativity objection to give up presentism should be moved by a related objection to give up actualism as well. If there is a reason to be an actualist without also being a presentist, it must go beyond the relativity objection to presentism. (shrink)

Presentism is the view that only presently existing things exist. Actualism is the view that only actually existing things exist. Although these views have much in common, the position we take with respect to one of them is not usually thought to constrain the position that we may take toward the other. In this paper I argue that this standard attitude deserves further scrutiny. In particular, I argue that the considerations that motivate one common objection to presentism—the grounding objection—threaten to (...) give rise to an analogous grounding objection to actualism. Those who are moved by grounding considerations to give up presentism should either be moved by analogous considerations to give up actualism as well or be prepared to undertake quite a bit of further work in order to defend their position.

ABSTRACT Temporal eliminativism is the view that the present is privileged because past and future entities do not exist. Temporal ersatzism is the view that the present is privileged because, although past and future entities exist, they are not concrete. I argue that shifting from temporal eliminativism to temporal ersatzism can help to address objections to the former theory that are due to relativity theory—but only if temporal ersatzism is understood in a fairly specific way and only in so far (...) as the temporal ersatzist is willing to take on some prima facie surprising commitments. I close by showing how the claims that I make with respect to temporal ersatzism generalise to other theories of time on which the present is privileged, including McDaniel’s [2018] presentist existential pluralism.

A distinguished cast of contributors explores the central feminist concerns in each arena, through the central metaphors of monster, mother goddess and cyborg.

In this paper, we present and defend the theoretical framework of an empirical model to describe people’s fundamental moral attitudes (FMAs) to animals, the stratification of FMAs in society and the role of FMAs in judgment on the culling of healthy animals in an animal disease epidemic. We used philosophical animal ethics theories to understand the moral basis of FMA convictions. Moreover, these theories provide us with a moral language for communication between animal ethics, FMAs, and public debates. We defend (...) that FMA is a two-layered concept. The first layer consists of deeply felt convictions about animals. The second layer consists of convictions derived from the first layer to serve as arguments in a debate on animal issues. In a debate, the latter convictions are variable, depending on the animal issue in a specific context, time, and place. This variability facilitates finding common ground in an animal issue between actors with opposing convictions. (shrink)

Das Sterben wird längst nicht mehr verdrängt und verschwiegen, es gehört vielmehr zu den ausgiebig erörterten Themen unserer Zeit. Viele Debatten ranken sich um Sterbehilfe und um die Frage, was einen guten Tod ausmacht. Dabei scheinen wir uns bemerkenswert einig zu sein, dass gut stirbt, wer bis zuletzt er oder sie selbst bleibt. Wir wünschen uns, so die These dieses Buches, unseren 'eigenen Tod': ein Lebensende, wie es uns entspricht, ein authentisches Sterben. Dieses Ideal leitet in unterschiedlicher Weise die Palliativversorgung (...) und die Sterbehilfebewegung an. Doch Nina Streeck zeigt, dass sich das, was so erstrebenswert klingt, als anspruchsvoll entpuppt. Die Idee des 'eigenen Todes' droht sich in ihr Gegenteil zu verkehren: in einen Zwang zum authentischen Sterben."--Page 4 of cover. (shrink)

For decades now, environmental philosophers from Arne Næss to Freya Mathews have dreamt of environmental ethics that “make things happen.” We contend such ethics can be found in Nordic children’s tales—those scriptures of moral guidance, and influential propellers of environmental action. In this essay we discuss the moral-imaginative worlds of fictitious in Nordic children’s tales, choosing some of the most canonical stories of the Nordics as our focal point. We argue the complex and often inconsistent philosophical mediations between human and (...) more-than-human worlds as imagined by Astrid Lindgren, Selma Lagerlöf, Thorbjørn Egner, or Tove Jansson are as viable philosophical works as other, more systematic studies in environmental ethics. Further, we argue that places, or indeed larger geographical regions, animate the moral imagination of the characters who live there, suggesting there is a reciprocal and mutually enhancing relationship between dwelling, thinking, and acting, between being animated and becoming animateur. Indeed, we may speak of this animated and animating, cultural-ecological topos as part of a genuine Nordic Ecosphere. Coruscating in this ecosphere are the sparkles of ‘literary ecological ethics,’ which influence human actions, not as much through analysis, documentation, or argument as through world-making stories, images, and models of environmental heroines.

IntroductionIn the context of giving risk information for obtaining informed consent, it is not easy to comply with the ethical principle of “primum nihil nocere.” Carelessness, ignorance of nocebo effects and a misunderstood striving for legal certainty can lead doctors to comprehensive and brutal risk information. It is known that talking about risks and side effects can even trigger those and result in distress and nonadherence to medication or therapy.MethodsRecently, we have reported on significant clinically relevant effects of verbal and (...) non-verbal suggestions on maximal muscular arm strength in healthy volunteers and in patients at two time points before surgery. Maximal strength during arm abduction was measured by dynamometry of the deltoid muscle group. Suggestions from clinical everyday life were formulated as presumed negative and neutral versions.ResultsHere, we report on the effects of two versions of risk information in 45 patients. After sole mentioning risks of a puncture for the placement of a pain catheter, the maximal arm muscle strength was significantly reduced to 83% of baseline several days, and to 84% the evening before surgery. Strength was not significantly decreased and close to baseline at T1 and T2 when risks and benefits of a pain catheter were combined in one sentence. The difference between both versions was significant. With persistent normal distribution of values, the effect was due to uniform reactions of many patients, not to strong reactions of a few. High suggestibility and increase of anxiety with approaching surgery were identified as influencing factors for the neutralizing effect of modified wording.ConclusionWe not only suggest an alternative formulation for risk information to avoid nocebo effects but present an objective method to quantify and compare effects of different wordings. Thereby, we provide evidence that concurrently given positive aspects can neutralize negative effects during medical interview. (shrink)

The theory of causal Bayes nets [15, 19] is, from an empirical point of view, currently one of the most promising approaches to causation on the market. There are, however, counterexamples to its core axiom, the causal Markov condition. Probably the most serious of these counterexamples are EPR/B experiments in quantum mechanics (cf. [13, 23]). However, these are also the only counterexamples yet known from the quantum realm. One might therefore wonder whether they are the only phenomena in the quantum (...) realm that create problems for causal Bayes nets. The aim of this paper is to demonstrate that not only the phenomenon of quantum correlations in EPR/B experiments create problems for causal Bayes nets, but also the temporal evolution of quantum systems, which is described as dualistic by quantum mechanics. For this purpose, it is shown that single photon experiments in a Mach-Zehnder interferometer (MZI) violate the causal Markov condition as well. It is then argued, however, that the Markov violation does not occur under the de Broglie-Bohm interpretation of Bohmian mechanics. (shrink)

Some theories of quantum mechanical phenomena endorse wave function realism, according to which the physical space we inhabit is very different from the physical space we appear to inhabit. In this paper I explore an argument against wave function realism that appeals to a type of simplicity that, although often overlooked, plays a crucial role in scientific theory choice. The type of simplicity in question is simplicity of fit between the way a theory says the world is and the way (...) the world appears to be. This argument can be understood as one way of spelling out the so-called “incredulous stare objection” that is sometimes leveled against surprising metaphysical theories. (shrink)

The paper is concerned with the psychological relevance of a logical model for deductive reasoning. We propose a new way to analyze logical reasoning in a deductive version of the Mastermind game implemented within a popular Dutch online educational learning system (Math Garden). Our main goal is to derive predictions about the difficulty of Deductive Mastermind tasks. By means of a logical analysis we derive the number of steps needed for solving these tasks (a proxy for working memory load). Our (...) model is based on the analytic tableaux method, known from proof theory. We associate the difficulty of Deductive Mastermind game-items with the size of the corresponding logical trees obtained by the tableaux method. We derive empirical hypotheses from this model. A large group of students (over 37 thousand children, 5–12 years of age) played the Deductive Mastermind game, which gave empirical difficulty ratings of all 321 game-items. The results show that our logical approach predicts these item ratings well, which supports the psychological relevance of our model. (shrink)

The Lysis is one of Plato's most engaging but also puzzling dialogues; it has often been regarded, in the modern period, as a philosophical failure. The full philosophical and literary exploration of the dialogue illustrates how it in fact provides a systematic and coherent, if incomplete, account of a special theory about, and special explanation of, human desire and action. Furthermore, it shows how that theory and explanation are fundamental to a whole range of other Platonic dialogues and indeed to (...) the understanding of the corpus as a whole. Part One offers an analysis of, or running commentary on, the dialogue. In Part Two Professors Penner and Rowe examine the philosophical and methodological implications of the argument uncovered by the analysis. The whole is rounded off by an epilogue of the relation between the Lysis and some other Platonic texts. (shrink)

Selon Kirk Lougheed, favoriser une version objective de l’argument du sens de la vie établit une sorte d’antithéisme, c’est-à-dire une perspective qui maintient que l’existence d’un Dieu théiste aggraverait les choses et qu’il est donc plus rationnel de préférer que Dieu n’existe pas.
