BackgroundThe UN Convention on the Rights of Persons with Disabilities, and the reformed guardianship law in Germany, require that persons with a disability, including people with dementia in Alzheimer’s disease (PwAD), are supported in making self-determined decisions. This support is achieved through communication. While content-related communication is a deficit of PwAD, relational aspects of communication are a resource. Research in supported decision-making (SDM) has investigated the effectiveness of different content-related support strategies for PwAD but has only succeeded in improving understanding, (...) which, although one criterion of capacity to consent, is not sufficient to ensure overall capacity to consent. The aim of the ‘spatial intervention study’ of the DECIDE project is to examine an innovative resource-oriented SDM approach that focuses on relational aspects. We hypothesise that talking to PwAD in their familiar home setting (as opposed to a clinical setting) will reduce the complexity of the decision-making process and enhance overall capacity to consent. MethodsPeople with a suspected or confirmed diagnosis of dementia in Alzheimer’s disease will be recruited from two memory clinics (N = 80). We will use a randomised crossover design to investigate the intervention effect of the decision-making place on capacity to consent. Besides reasoning capacity, which is part of overall capacity to consent and will be the primary outcome, various secondary outcomes (e.g., other aspects of capacity to consent, subjective task complexity, decisional conflict) and suspected moderating or mediating variables (e.g., meaning of home, demographic characteristics) will be assessed.DiscussionThe results of the study will be used to develop a new SDM strategy that is based on relational resources for PwAD. If a change in location achieves the anticipated improvement in capacity to consent, future research should focus on implementing this SDM strategy in a cost-effective manner in clinical practice.Trial registration: DRKS00030799.

BackgroundEverybody has the right to decide whether to receive specific medical treatment or not and to provide their free, prior and informed consent to do so. As dementia progresses, people with Alzheimer’s dementia (PwAD) can lose their capacity to provide informed consent to complex medical treatment. When the capacity to consent is lost, the autonomy of the affected person can only be guaranteed when an interpretable and valid advance directive exists. Advance directives are not yet common in Germany, and their (...) validity is often questionable. Once the dementia diagnosis has been made, it is assumed to be too late to write an advance directive. One approach used to support the completion of advance directives is ‘Respecting Choices’®—an internationally recognised, evidence-based model of Advance Care Planning (ACP), which, until now, has not been evaluated for the target group of PwAD. This study’s aims include (a) to investigate the proportion of valid advance directives in a memory clinic population of persons with suspected AD, (b) to determine the predictors of valid advance directives, and (c) to examine whether the offer of ACP can increase the proportion of valid advance directives in PwAD.MethodWe intend to recruit at leastN = 250 participants from two memory clinics in 50 consecutive weeks. Of these, the first 25 weeks constitute the baseline phase (no offer of ACP), the following 25 weeks constitute the intervention phase (offer of ACP). The existence and validity of an advance directive will be assessed twice (before and after the memory clinic appointment). Moreover, potential predictors of valid advance directives are assessed.DiscussionThe results of this study will enhance the development of consent procedures for advance directives of PwAD based on the ACP/Respecting Choices (R) approach. Therefore, this project contributes towards increasing the autonomy and inclusion of PwAD and the widespread acceptance of valid advance directives in PwAD.Trial RegistrationDRKS, DRKS00026691, registered 15th of October 2021,https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00026691.

Variability is pervasive in spoken language, in particular if one is exposed to two varieties of the same language. Unlike in bilingual settings, standard and dialectal forms are often phonologically related, increasing the variability in word forms. We investigate whether dialectal variability in children’s input affects their ability to recognize words in Standard German, testing non-dialectal vs. dialectal children. Non-dialectal children, who typically grow up in urban areas, mostly hear Standard German forms, and hence encounter little segmental variability in their (...) input. Dialectal children in turn, who typically grow up in rural areas, hear both Standard German and dialectal forms, and are hence exposed to a large amount of variability in their input. We employ the familiar word paradigm for German children aged 12–18 months. Since dialectal children from rural areas are hard to recruit for laboratory studies, we programmed an App that allows all parents to test their children at home. Looking times to familiar vs. non-familiar words were analyzed using a semi-automatic procedure based on neural networks. Our results replicate the familiarity preference for non-dialectal German 12–18-month-old children. Non-dialectal children in the same age range, on the other hand, showed a novelty preference. One explanation for the novelty preference in dialectal children may be more mature linguistic processing, caused by more variability of word forms in the input. This linguistic maturation hypothesis is addressed in Experiment 2, in which we tested older children. These children, who are not exposed to dialectal forms, also showed a novelty preference. Taken together, our findings show that both dialectal and non-dialectal German children recognized the familiar Standard German word forms, but their looking pattern differed as a function of the variability in the input. Frequent exposure to both dialectal and Standard German word forms may hence have affected the nature of lexical representations, leading to more mature processing capacities. (shrink)

Consequentialism is the view that the rightness or wrongness of actions depend solely on their consequences. It is one of the most influential, and controversial, of all ethical theories. In this book, Julia Driver introduces and critically assesses consequentialism in all its forms. After a brief historical introduction to the problem, Driver examines utilitarianism, and the arguments of its most famous exponents, John Stuart Mill and Jeremy Bentham, and explains the fundamental questions underlying utilitarian theory: what value is to (...) be specified and how it is to be maximized. Driver also discusses indirect forms of consequentialism, the important theories of motive consequentialism and virtue consequentialism, and explains why the distinction between subjective and objective consequentialism is so important. Including helpful features such as a glossary, chapter summaries, and annotated further reading at the end of each chapter, Consequentialism is ideal for students seeking an authoritative and clearly explained survey of this important problem.

Los derechos humanos sólo adquieren sentido, para Julián Marías, en torno a la persona, una de las claves de su pensamiento.

Is the procreation asymmetry intuitively supported? According to a recent article in this journal, an experimental study suggests the opposite. Dean Spears (2020) claims that nearly three-quarters of participants report that there is a reason to create a person just because that person’s life would be happy. In reply, I argue that various confounding factors render the study internally invalid. More generally, I show how one might come to adopt the procreation asymmetry for the wrong reasons by misinterpreting one’s intuitions.

This paper offers a unified explanation for the procreation asymmetry and the non-identity thesis – two of the most intractable puzzles in population ethics. According to the procreation asymmetry, there are moral reasons not to create lives that are not worth living but no moral reasons to create lives that are worth living. I explain the procreation asymmetry by arguing that there are moral reasons to prevent the bad, but no moral reasons to promote the good. Various explanations for the (...) procreation asymmetry have failed to explain the non-identity thesis: if one could create a person with a good life or a different person with a better life, one has a moral reason to create the better life. I argue that reflections on the misfortune of unfulfilled potential allow us to circumvent the non-identity problem. (shrink)

Julia Annas offers a new account of virtue and happiness as central ethical ideas. She argues that exercising a virtue involves practical reasoning of the kind we find in someone exercising an everyday practical skill, such as farming, building, or playing the piano. This helps us to see virtue as part of an agent's happiness or flourishing.

Is there a pro tanto moral reason to create a life merely because it would be good for the person living it? Proponents of the procreation asymmetry claim there is not. Defending this controversial no reason claim, some have suggested that it is well in line with other phenomena in the moral realm: there is no reason to give a promise merely because one would keep it, and there is no reason to procreate merely to increase the extent of justice (...) in the world. Allegedly, some analogs extend so far as to support a unified theory of the no reason claim and the nonidentity thesis, that is, the view that of two persons leading lives of positive wellbeing, there is a reason to create the person with higher wellbeing. I dismantle the proposed analogs and show that they fail to meet various desiderata. Moreover, I refute Johann Frick's argument that the no reason claim follows from the assumption that reasons of beneficence are reasons to act for the sake of people. By criticizing attractive defenses for the no reason claim, I weaken its plausibility. (shrink)

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

ABSTRACT I propose a division of the literature on natural kinds into metaphysical worries, semantic worries, and methodological worries. I argue that the latter set of worries, which concern how classification influences scientific practices, should occupy centre stage in philosophy of science discussions about natural kinds. I apply this methodological framework to the problems of classifying chemical species and nanomaterials. I show that classification in nanoscience differs from classification in chemistry because the latter relies heavily on compositional identity, whereas the (...) former must consider additional properties, namely, size, shape, and surface chemistry. I use this difference to argue for a scale-dependent theory of scientific classification. _1_ Introduction _2_ The Methodological Problem of Kinds _3_ Chemical Kindhood: Reactivity, Microstructure, and the Structure–Property Paradigm _4_ Scale-Dependence and Nanoscale Kinds _5_ Conclusion.

Experiences—visual, emotional, or otherwise—play a role in providing us with justification to believe claims about the world. Some accounts of how experiences provide justification emphasize the role of the experiences’ distinctive phenomenology, i.e. ‘what it is like’ to have the experience. Other accounts emphasize the justificatory role to the experiences’ etiology. A number of authors have used cases of cognitively penetrated visual experience to raise an epistemic challenge for theories of perceptual justification that emphasize the justificatory role of phenomenology rather (...) than etiology. Proponents of the challenge argue that cognitively penetrated visual experiences can fail to provide the usual justification because they have improper etiologies. However, extant arguments for the challenge’s key claims are subject to formidable objections. In this paper, I present the challenge’s key claims, raise objections to previous attempts to establish them, and then offer a novel argument in support of the challenge. My argument relies on an analogy between cognitively penetrated visual and emotional experiences. I argue that some emotional experiences fail to provide the relevant justification because of their improper etiologies and conclude that analogous cognitively penetrated visual experiences fail to provide the relevant justification because of their etiologies, as well.

We discuss the idea that superpositions in quantum mechanics may involve contradictions or contradictory properties. A state of superposition such as the one comprised in the famous Schrödinger’s cat, for instance, is sometimes said to attribute contradictory properties to the cat: being dead and alive at the same time. If that were the case, we would be facing a revolution in logic and science, since we would have one of our greatest scientific achievements showing that real contradictions exist.We analyze that (...) claim by employing the traditional square of opposition.We suggest that it is difficult to make sense of the idea of contradiction in the case of quantum superpositions. From a metaphysical point of view the suggestion also faces obstacles, and we present some of them. (shrink)

This interpretive introduction provides unique insight into Plato's Republic. Stressing Plato's desire to stimulate philosophical thinking in his readers, Julia Annas here demonstrates the coherence of his main moral argument on the nature of justice, and expounds related concepts of education, human motivation, knowledge and understanding. In a clear systematic fashion, this book shows that modern moral philosophy still has much to learn from Plato's attempt to move the focus from questions of what acts the just person ought to (...) perform to the more profound questions of what sort of person the just person ought to be.

Wie lassen sich Banalität, Trivialität und Kitsch voneinander unterscheiden und welche Rolle spielen sie für Kunst und Literatur? Zur Beantwortung dieser Fragen betrachtet Julia Genz Banalität, Trivialität und Kitsch als Bestandteile von Diskursen, in denen Zugänglichkeit bewertet wird. Zugänglichkeit ist dabei nicht von vornherein gegeben, sondern muss diskursiv erst hergestellt werden. Durch die Ausdifferenzierung in soziale, kognitive und emotionale Zugänglichkeit lassen sich die drei bislang nicht überzeugend getrennten Bereiche voneinander abgrenzen und mit ihren Gegenpolen Exklusivität, Komplexität und Kunst in (...) ein umfassendes Ästhetikmodell integrieren.

How does history relate to the past? According to leading historical theorists, the relation to the past in history is reducible to evidential, psychological, practical and retrospective concerns. In contrast, this volume claims that historical relations to the past are irreducible products of the logical commitments of history as method. Ahlskog argues that the method of history shapes and enables relations to past in historical research by invoking past perspectives of meaning for rendering reality intelligible. The book provides a much-needed (...) philosophical clarification of key concepts in one of the most fundamental debates within the humanities today. (shrink)

Following J.-Y.Béziau in his pioneer work on non-standard interpretations of the traditional square of opposition, we have applied the abstract structure of the square to study the relation of opposition between states in superposition in orthodox quantum mechanics in [1]. Our conclusion was that such states are contraries, contradicting previous analyzes that have led to different results, such as those claiming that those states represent contradictory properties. In this chapter we bring the issue once again into the center of the (...) stage, but now discussing the metaphysical presuppositions which underlie each kind of analysis and which lead to each kind of result, discussing in particular the idea that superpositions represent potential contradictions. We shall argue that the analysis according to which states in superposition are contrary rather than contradictory is still more plausible. (shrink)

In this work, we focus on a very specific case study: assuming that quantum theories deal with “particles” of some kind, what kind of entity can such particles be? One possible answer, the one we shall examine here, is that they are not the usual kind of object found in daily life: individuals. Rather, we follow a suggestion by Erwin Schrödinger, according to which quantum mechanics poses a revolutionary kind of entity: non-individuals. While physics, as a scientific field, is not (...) concerned with whether entities posited by a specific physical theory are individuals or not, answering this question is part of the quest for a better understanding of physical reality. Here lies, in large measure, the relevance of ontology. (shrink)

This paper concerns how extant theorists of predictive coding conceptualize and explain possible instances of cognitive penetration. §I offers brief clarification of the predictive coding framework and relevant mechanisms, and a brief characterization of cognitive penetration and some challenges that come with defining it. §II develops more precise ways that the predictive coding framework can explain, and of course thereby allow for, genuine top-down causal effects on perceptual experience, of the kind discussed in the context of cognitive penetration. §III develops (...) these insights further with an eye towards tracking one extant criterion for cognitive penetration, namely, that the relevant cognitive effects on perception must be sufficiently direct. Throughout these discussions, we extend the analyses of the predictive coding models, as we know them. So one open question that surfaces is how much of the extended analyses are genuinely just part of the predictive coding models, or something that must be added to them in order to generate these additional explanatory benefits. In §IV, we analyze and criticize a claim made by some theorists of predictive coding, namely, that (interesting) instances of cognitive penetration tend to occur in perceptual circumstances involving substantial noise or uncertainty. It is here that our analysis is most critical. We argue that, when applied, the claim fails to explain (or perhaps even be consistent with) a large range of important and uncontroversially interesting possible cases of cognitive penetration. We conclude with a general speculation about how the recent work on the predictive mind may influence the current dialectic concerning top-down effects on perception. (shrink)

The strategy of developing an ontology or models of disability as a prior step to settling ethical issues regarding disabilities is highly problematic for two reasons. First, key definitional aspects of disability are normative and cannot helpfully be made value-neutral. Second, if we accept that the contested concept of disability is value-laden, it is far from obvious that there are definitive reasons for choosing one interpretation of the concept over another. I conclude that the concept of disability is better left (...) ethically open-ended or broad enough to encompass the examination of various ethical issues. Alternatively, the concept of disability could be altogether abandoned in order to focus on specific issues without being hindered by debates about the nature of disability. Only political costs, rather than conceptual considerations internal to the models, could be weighed against such a conclusion. (shrink)

Scientific realism is typically associated with metaphysics. One current incarnation of such an association concerns the requirement of a metaphysical characterization of the entities one is being a realist about. This is sometimes called “Chakravartty’s Challenge”, and codifies the claim that without a metaphysical characterization, one does not have a clear picture of the realistic commitments one is engaged with. The required connection between metaphysics and science naturally raises the question of whether such a demand is appropriately fulfilled, and how (...) metaphysics engages with science in order to produce what is called “scientific metaphysics”. Here, we map some of the options available in the literature, generating a conceptual spectrum according to how each view approximates science and metaphysics. This is done with the purpose of enlightening the current debate on the possibility of epistemic warrant that science could grant to such a metaphysics, and how different positions differently address the thorny issue concerning such a warrant.

Nonrelativistic quantum mechanics (QM) works perfectly well for all practical purposes. Once one admits, however, that a successful scientific theory is supposed not only to make predictions but also to tell us a story about the world in which we live, a philosophical problem emerges: in the specific case of QM, it is not possible to associate with the theory a unique scientific image of the world; there are several images. The fact that the theory may be compatible with distinct (...) ontologies, and that those ontologies may themselves be associated with a plurality of metaphysical approaches, gives rise to the problem of metaphysical underdetermination. This paper concludes that the available metametaphysical criteria fail to deliver objectivity in theory choice, and it puts forward its own criterion based on a tension between two methods of metaphysical inquiry: one that is closely related to science and another that is not.

In this paper we deal with two applications of the square of opposition to controversial issues in the philosophy of quantum mechanics. The first one concerns the kind of opposition represented by states in superposition. A superposition of “spin up” and “spin down” for a given spatial direction, for instance, is sometimes said to originate particular kinds of opposition such as contradictoriness. The second application concerns the problem of identical particles. Identity and indiscernibility are entangled in discussions of this problem (...) in such a way that a proper conceptual treatment of those issues through the square seems profitable. (shrink)

This paper investigates the norm of presupposition, as one pervasive type of indirect speech act. It argues against the view that sees presuppositions as an indirect counterpart of the direct speech act of assertion and proposes instead that they are much more similar to the direct speech act of assumption. More concretely, it suggests that the norm that governs presuppositions is not an epistemic or doxastic attitude such as knowledge, justified belief, or mere belief; it's a practical attitude, most plausibly (...) the attitude of rational acceptance. This view has important ramifications well beyond debates in philosophy of language and linguistics. It affects not only our view of which speech act sequences are fine and which are off; it bears on whether presuppositions can function as testimony, whether they can be lies, and whether they are ontologically committal, thus addressing central topics in epistemology, ethics, and metaphysics.

This volume launches a new series of contemporary conversations about scientific classification. Most philosophical conversations about kinds have focused centrally or solely on natural kinds, that is, kinds whose existence is not dependent on the scientific process of synthesis. This volume refocuses conversations about classification on unnatural, or synthetic, kinds via extensive study of three paradigm cases of unnatural kinds: nanomaterials, stem cells, and synthetic biology.

Sentences containing predicates of personal taste exhibit two striking features: whether they are true seems to lie in the eye of the beholder and whether they are true can be—and often is—subject to disagreement. In the last decade, there has been a lively debate about how to account for these two features. In this paper, I shall argue for two claims: first, I shall show that even the most promising approaches so far offered by proponents of so-called indexical contextualism fail (...) to account for the disagreement feature. They might be able to account for some disagreement data, but they have trouble accounting for two kinds of disagreement data that caused the estrangement from indexical contextualism and the migration to relativism in the first place: the denial and the retraction data. Second, I shall show that we still do not have to abandon indexical contextualism, because what I shall call the superiority approach—a new pragmatically extended version of indexical contextualism—can very well account for the data.

In this book, Julia Ching offers a survey of over 4,000 years of Chinese civilization through an examination of the relationship between kingship and mysticism. She investigates the sage-king myth and ideal, arguing that institutions of kingship were bound up with cultivation of trance states and communication with spirits. Over time, the sage-king myth became a model for the actual ruler. As a paradigm, it was also appropriated by private individuals who strove for wisdom without becoming kings. As the (...) Confucian tradition interacted with the Taoist and the Buddhist, the religious character of spiritual and mystical cultivation became more pronounced. But the sage-king idea continued, promoting expectations of benevolent despotism rather than democratization in Chinese civilization. (shrink)

Many people follow Grice in thinking that all conversational implicatures are cancellable. And often enough, they use this insight as a test for conversational implicatures. If you want to find out whether something is a conversational implicature, the test has it, you should ask yourself whether the thing in question is cancellable; if you find that it is not cancellable, you can infer that it is not a conversational implicature. If you find that it is cancellable, you can infer that (...) it might well be a conversational implicature and that you should now do further testing. Various philosophers and linguists have questioned the test however. Some have held that Grice's cancellability claim is subject to counterexamples and that the test is not reliable. Others have argued that even though Grice's claim can be defended against the examples in question, the test is not as informative as people have hoped. This article provides an overview of the recent discussion on the cancellability test and suggests a way forward. (shrink)

A close examination of the literature on ontology may strike one with roughly two distinct senses of this word. According to the first of them, which we shall call traditional ontology , ontology is characterized as the a priori study of various “ontological categories”. In a second sense, which may be called naturalized ontology , ontology relies on our best scientific theories and from them it tries to derive the ultimate furniture of the world. From a methodological point of view (...) these two senses of ontology are very far away. Here, we discuss a possible relationship between these senses and argue that they may be made compatible and complement each other. We also examine how logic, understood as a linguistic device dealing with the conceptual framework of a theory and its basic inference patterns must be taken into account in this kind of study. The idea guiding our proposal may be put as follows: naturalized ontology checks for the applicability of the ontological categories proposed by traditional ontology and give substantial feedback for it. The adequate expression of some of the resulting ontological frameworks may require a different logic. We conclude with a discussion of the case of orthodox quantum mechanics, arguing that this theory exemplifies the kind of relationship between the two senses of ontology. We also argue that the view proposed here may throw some light in ontological questions concerning this theory. (shrink)

Recently, macroscopic accounts of chemical kind individuation have been proposed as alternatives to the microstructural essentialist account advocated by Kripke, Putnam, and others. These accounts argue that individuation of chemical kinds is based on macroscopic criteria such as reactivity or thermodynamics, and they challenge the essentialism that grounds the Kripke-Putnam view. Using a variety of chemical examples, I argue that microstructure grounds these macroscopic accounts, but that this grounding need not imply essentialism. Instead, kinds are individuated on the basis of (...) similarity of reactivity between substances, and microstructure explains similarity of reactivity. (shrink)

Public or stakeholder participation in environmental governance has been strongly advocated within the United Nations (UN) since the early 1990s. A relatively new mechanism for global climate finance that emphasises stakeholder engagement is the Green Climate Fund (GCF), a UN strategy for channelling funds from the Global North to the Global South. Drawing on previous critical approaches to multi-stakeholder involvement in global governance, this article explores stakeholder involvement within the GCF. The study combines ideas from institutional logics and resource dependency (...) to provide a better understanding of how stakeholder arrangements are shaped in climate organisations. Results show that the GCF stakeholder arrangement favours private sector stakeholders – stakeholders that take a technical and apolitical approach to climate finance – and disfavours smaller, less resourceful stakeholders as well as those who perform a politicised watchdog function.

The first decade of event-related potential (ERP) research had established that the most consistent correlates of the onset of visual consciousness are the early visual awareness negativity (VAN), a posterior negative component in the N2 time range, and the late positivity (LP), an anterior positive component in the P3 time range. Two earlier extensive reviews ten years ago had concluded that VAN is the earliest and most reliable correlate of visual phenomenal consciousness, whereas LP probably reflects later processes associated with (...) reflective/access consciousness. This article provides an update to those earlier reviews. ERP and MEG studies that have appeared since 2010 and directly compared ERPs between aware and unaware conditions are reviewed, and important new developments in the field are discussed. The result corroborates VAN as the earliest and most consistent signature of visual phenomenal consciousness, and casts further doubt on LP as an ERP correlate of phenomenal consciousness. (shrink)

The Received View on quantum non-individuality is, roughly speaking, the view according to which quantum objects are not individuals. It seems clear that the RV finds its standard expression nowadays through the use of the formal apparatuses of non-reflexive logics, mainly quasi-set theory. In such logics, the relation of identity is restricted, so that it does not apply for terms denoting quantum particles; this “lack of identity” formally characterizes their non-individuality. We face then a dilemma: on the one hand, identity (...) seems too important to be given up, on the other hand the RV seems to require that identity be given up. In this paper we shall discuss how the specific characterization of the RV through non-reflexive logics came to be framed. We examine some of the main objections to this version of the RV and argue that they are misguided under this specific “non-reflexive” understanding of the RV. Finally, we shall also argue that this non-reflexive view is not the only option for a metaphysical articulation of the RV: less radical approaches to identity and logic are open. In particular, some of these alternative approaches to the RV we present may be immune to most of the criticisms presented against the non-reflexive approach. (shrink)

Outlines of Scepticism, by the Greek philosopher Sextus Empiricus, is a work of major importance for the history of Greek philosophy. It is the fullest extant account of ancient scepticism, and it is also one of our most copious sources of information about the other Hellenistic philosophies. Its first part contains an elaborate exposition of the Pyrrhonian variety of scepticism; its second and third parts are critical and destructive, arguing against 'dogmatism' in logic, epistemology, science and ethics - an approach (...) that revolutionized the study of philosophy when Sextus' works were rediscovered and published in the sixteenth century. This volume presents the accurate and readable translation which was first published in 1994, together with a substantial new historical and philosophical introduction by Jonathan Barnes. (shrink)

Ontic Structural Realism is a version of realism about science according to which by positing the existence of structures, understood as basic components of reality, one can resolve central difficulties faced by standard versions of scientific realism. Structures are invoked to respond to two important challenges: one posed by the pessimist meta-induction and the other by the underdetermination of metaphysics by physics, which arises in non-relativistic quantum mechanics. We argue that difficulties in the proper understanding of what a structure is (...) undermines the realist component of the view. Given the difficulties, either realism should be dropped or additional metaphysical components not fully endorsed by science should be incorporated. (shrink)

People disagree frequently, about both objective and subjective matters. But while at least one party must be wrong in a disagreement about objective matters, it seems that both parties can be right when it comes to subjective ones: it seems that there can be faultless disagreements. But how is this possible? How can people disagree with one another if they are both right? And why should they? In recent years, a number of philosophers and linguists have argued that we must (...) become relativists about truth to understand faultless disagreements. This book shows that we can dispense with relativism. It combines a more standard semantics with a novel pragmatic theory to develop a superior approach. The book discusses both classic and recent literature in philosophy and linguistics. It provides a general introduction to the debate about the semantics and pragmatics of perspectival expressions, as well as an original contribution to the contemporary discussion. (shrink)
