Metaphysical dialetheism is the belief that there are contradictions in the world. I will argue that metaphysical dialetheism is, rightfully understood, the most controversial form of dialetheism, and further that it remains an open possibility. Dialetheism can come in many different forms, but all share the same belief in “dialethas”. Depending on how we understand what it means to be a contradiction, we will develop correspondingly different understandings of dialetheism. I will explore what different versions of the position might look (...) like, and how some of these versions of dialetheism could be more plausible than others, and argue that metaphysical dialetheism is the most interesting form of dialetheism. While few authors have considered the possibility of metaphysical dialetheism, there are some important arguments against the position to consider. Frederick Kroon argued in his 2004 article, _Realism and Dialetheism_, that in so far as we find arguments for dialetheism persuasive, we also have good reason to reject realism. Tumoas Tahko argued against the possibility of metaphysical dialetheism by explicitly arguing for a metaphysical definition of contradiction, and a metaphysical version of LNC. Graham Priest also challenged the idea of a “consistent” metaphysics in principle. This paper will take up all of these challenges, and defend the possibility of a metaphysical dialetheist position.

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

We have identified a sample of 53 societies outside of the classical Himalayan and Marquesean area that permit polyandrous unions. Our goal is to broadly describe the demographic, social, marital, and economic characteristics of these societies and to evaluate some hypotheses of the causes of polyandry. We demonstrate that although polyandry is rare it is not as rare as commonly believed, is found worldwide, and is most common in egalitarian societies. We also argue that polyandry likely existed during early human (...) history and should be examined from an evolutionary perspective. Our analysis reveals that it may be a predictable response to a high operational sex ratio favoring males and may also be a response to high rates of male mortality and, possibly, male absenteeism. Other factors may contribute, but our within-polyandry sample limits analysis. (shrink)

Social groups—like teams, committees, gender groups, and racial groups—play a central role in our lives and in philosophical inquiry. Here I develop and motivate a structuralist ontology of social groups centered on social structures (i.e., networks of relations that are constitutively dependent on social factors). The view delivers a picture that encompasses a diverse range of social groups, while maintaining important metaphysical and normative distinctions between groups of different kinds. It also meets the constraint that not every arbitrary collection of (...) people is a social group. In addition, the framework provides resources for developing a broader structuralist view in social ontology. (shrink)

Most theories about virtue cultivation fall under the general umbrella of the role model approach, according to which virtue is acquired by emulating role models, and where those role models are usually conceived of as superior in some relevant respect to the learners. I argue that although we need role models to cultivate virtue, we also need good and close relationships with people who are not our superiors. The overemphasis on role models is misguided and misleading, and a good antidote (...) draws on the Aristotelian concept of character friendship. Character friendship constitutes a unique form of experience in which we share a substantial way of seeing with a close other; facilitates a unique form of knowledge, the knowledge of a particular person ; develops other emotions important for virtue cultivation besides admiration, such as love, shame, trust, and hope; and is a praxis in which cooperative interactions and discussions function as a bridge between habituation of virtue at home and the public life. Character friendship provides necessary elements for human cultivation of virtue that the sole experience of having a role model does not. (shrink)

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

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

Social groups, including racial and gender groups and teams and committees, seem to play an important role in our world. This article examines key metaphysical questions regarding groups. I examine answers to the question ‘Do groups exist?’ I argue that worries about puzzles of composition, motivations to accept methodological individualism, and a rejection of Racialism support a negative answer to the question. An affirmative answer is supported by arguments that groups are efficacious, indispensible to our best theories, and accepted given (...) common sense. Then, I turn to an examination of the features of social groups. I argue that social groups can be divided into two sorts. Groups of Type 1 are organized social groups like courts and clubs. Groups of Type 2 are groups like Blacks, women, and lesbians. While groups of both sorts have some features in common, they also have marked differences in features. Finally, I turn to views of the nature of social groups. I argue that the difference in features provides evidence that social groups do not have a uniform nature. Teams and committees are structured wholes, while race and gender groups are social kinds. (shrink)

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

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

In this paper I argue for a view of groups, things like teams, committees, clubs and courts. I begin by examining features all groups seem to share. I formulate a list of six features of groups that serve as criteria any adequate theory of groups must capture. Next, I examine four of the most prominent views of groups currently on offer—that groups are non-singular pluralities, fusions, aggregates and sets. I argue that each fails to capture one or more of the (...) criteria. Last, I develop a view of groups as realizations of structures. The view has two components. First, groups are entities with structure. Second, since groups are concreta, they exist only when a group structure is realized. A structure is realized when each of its functionally defined nodes or places are occupied. I show how such a view captures the six criteria for groups, which no other view of groups adequately does, while offering a substantive answer to the question, “What are groups?”. (shrink)

Highlighting main issues and controversies, this book brings together current philosophical discussions of symmetry in physics to provide an introduction to the subject for physicists and philosophers. The contributors cover all the fundamental symmetries of modern physics, such as CPT and permutation symmetry, as well as discussing symmetry-breaking and general interpretational issues. Classic texts are followed by new review articles and shorter commentaries for each topic. Suitable for courses on the foundations of physics, philosophy of physics and philosophy of science, (...) the volume is a valuable reference for students and researchers. (shrink)

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

Recently several philosophers have argued that racial, gender, and other social generic generalizations should be avoided given their propensity to promote essentialist thinking, obscure the social nature of categories, and contribute to oppression. Here I argue that a general prohibition against social generics goes too far. Given that the truth of many generics require regularities or systematic rather than mere accidental correlations, they are our best means for describing structural forms of violence and discrimination. Moreover, their accuracy, their persistence in (...) the face of counterexamples, and features of the contemporary socio-political context make generics useful linguistic tools in social justice projects.

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

Some language encourages essentialist thinking. While philosophers have largely focused on generics and essentialism, I argue that nouns as a category are poised to refer to kinds and to promote representational essentializing. Our psychological propensity to essentialize when nouns are used reveals a limitation for anti-essentialist ameliorative projects. Even ameliorated nouns can continue to underpin essentialist thinking. I conclude by arguing that representational essentialism does not doom anti-essentialist ameliorative projects. Rather it reveals that would-be ameliorators ought to attend to the (...) propensities for our representational devices to essentialize and to the complex relationship between essentialism and prejudice.

Sartre considers the rise of spontaneous not cognitive consciousness or prereflexive cogito as a subject. Without any conditions, without any nature or essence can be determined. The awareness event as an absolute necessity is indeed unjustifiable that refers to the world, is pure intentionality. The abstract ideal of freedom for Sartre is a conscience without any determination. Man is free because it is free of any determination by precognitive structure of consciousness.

Como resultado del renacimiento de la ética de la virtud se generaron por lo menos dos grandes reacciones: una que afirma que esta ética es redundante, porque las teorías morales modernas incluyen —o pueden incluir— las virtudes, y otra que afirma que ésta es más amplia y completa, porque aborda la vida moral de mejor manera al poner el énfasis en lo más importante: el carácter moral. En el presente trabajo examino tanto el renacimiento del tema como el debate posterior, (...) y planteo una posible razón para preferir la ética de la virtud. (shrink)

Este artículo reconstruye panorámicamente la posición de Agustín de Hipona con respecto a la filosofía en la obra De civitate Dei. Sostiene que la valoración y el reproche que le hace Agustín a los platonici descansan en último término en un concepto de filosofía tomado del mismo platonismo y reinterpretado según textos bíblicos que enfatizan la centralidad de la mediación y el culto para alcanzar la beata vita.

Psychedelics such as psilocybin reliably produce significantly altered states of consciousness with a variety of subjectively experienced effects. These include certain changes to perception, cognition, and affect,1 which we refer to here as the acute subjective effects of psychedelics. In recent years, psychedelics such as psilocybin have also shown considerable promise as therapeutic agents when combined with talk therapy, for example, in the treatment of major depression or substance use disorder.2 However, it is currently unclear whether the aforementioned acute subjective (...) effects are necessary to bring about the observed therapeutic effects of psilocybin and other psychedelics. This uncertainty has sparked a lively—though still largely hypothetical—debate on whether psychedelics without subjective effects (“nonsubjective psychedelics” or “non-hallucinogenic psychedelics”) could still have the same therapeutic impact, or whether the acute subjective effects are in fact necessary for this impact to be fully realized.3,4,5.

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

ABSTRACT:Psychedelics, including psilocybin, and other consciousness-altering compounds such as 3,4-methylenedioxymethamphetamine (MDMA), currently are being scientifically investigated for their potential therapeutic uses, with a primary focus on measurable outcomes: for example, alleviation of symptoms or increases in self-reported well-being. Accordingly, much recent discussion about the possible value of these substances has turned on estimates of the magnitude and duration of persisting positive effects in comparison to harms. However, many have described the value of a psychedelic experience with little or no reference (...) to such therapeutic benefits, instead seeming to find the experience valuable in its own right. How can we make sense of such testimony? Could a psychedelic experience be valuable even if there were no persisting beneficial effects? If so, how? Using the concept of psychological richness, combined with insights from the philosophy of aesthetics and the enhancement literature, this essay explores potential sources of value in the acute subjective experience, apart from the value derived from persisting beneficial effects.

La realidad social, política, económica y sanitaria que experimentamos hoy denota que vivimos una crisis planetaria que convulsa al conjunto de las relaciones sociales. Es un imperativo teórico, retomar la fecundidad del concepto de persona y la crítica de Emmanuel Mounier al positivismo y al marxismo del siglo XX. Su crítica se basó en la noción de persona, de profunda raíz en la teología cristiana occidental y hoy considerado Patrimonio Cultural de la Humanidad al permitir fundamentar la validez global de (...) los Derechos Humanos y la posibilidad de la creación de una Ética Universal. En la presente investigación se propone redimensionar el valor de la filosofía personalista de Mounier y su activismo evangélico hacia los pobres, como un nuevo humanismo de una dimensión más que teórica, práctica. A través de una revisión cronológica y bibliográfica de los momentos más relevantes del personalismo, esta investigación se propone en su conclusión, comprender la fecundidad de la reflexión del concepto de persona, como de la vigencia de la crítica de este pensador al positivismo y al marxismo; para contribuir a situar el eje ético y político- social de la actual situación sociosanitaria que atraviesa la humanidad.

Symmetry, intended as invariance with respect to a transformation (more precisely, with respect to a transformation group), has acquired more and more importance in modern physics. This Chapter explores in 8 Sections the meaning, application and interpretation of symmetry in classical physics. This is done both in general, and with attention to specific topics. The general topics include illustration of the distinctions between symmetries of objects and of laws, and between symmetry principles and symmetry arguments (such as Curie's principle), and (...) reviewing the meaning and various types of symmetry that may be found in classical physics, along with different interpretative strategies that may be adopted. Specific topics discussed include the historical path by which group theory entered classical physics, transformation theory in classical mechanics, the relativity principle in Einstein's Special Theory of Relativity, general covariance in his General Theory of Relativity, and Noether's theorems. In bringing these diverse materials together in a single Chapter, we display the pervasive and powerful influence of symmetry in classical physics, and offer a possible framework for the further philosophical investigation of this topic.

This essay, written by a biologist, a microbial ecologist, a biological anthropologist, and an anthropologist‐historian, examines tensions and translations in microbiome research on animals in the laboratory and field. The authors trace how research questions and findings in the laboratory are extrapolated into the field and vice versa, and the shifting evidentiary standards that these research settings require. Showing how complexities of microbiomes challenge traditional standards of causation, the authors contend that these challenges require new approaches to inferences used in (...) ecology, anthropology, and history. As social scientists incorporate investigations of microbial life into their human studies, microbiome researchers venture into field settings to develop mechanistic understandings about the functions of complex microbial communities. These efforts generate new possibilities for cross‐fertilizations and inference frameworks to interpret microbiome findings. Microbiome research should integrate multiple scales, levels of variability, and other disciplinary approaches to tackle questions spanning conditions from the laboratory to the field. (shrink)

Slurs are expressions that can be used to demean and dehumanize targets based on their membership in racial, ethnic, religious, gender, or sexual orientation groups. Almost all treatments of slurs posit that they have derogatory content of some sort. Such views—which I call content-based—must explain why in cases of appropriation slurs fail to express their standard derogatory contents. A popular strategy is to take appropriated slurs to be ambiguous; they have both a derogatory content and a positive appropriated content. However, (...) if appropriated slurs are ambiguous, why can only members in the target group use them to express a non-offensive/positive meaning? Here, I develop and motivate an answer that could be adopted by any content-based theorist. I argue that appropriated contents of slurs include a plural fi rst-person pronoun. I show how the semantics of pronouns like ‘we’ can be put to use to explain why only some can use a slur to express its appropriated content. Moreover, I argue that the picture I develop is motivated by the process of appropriation and helps to explain how it achieves its aims of promoting group solidarity and positive group identity.

This book has two main and connected themes - the conception and articulation of time in the Greek world and the creation of history, especially in the context of the Greek city. Both how time is expressed and how the past is presented have often been seen as reflections of society. By looking at the construction of the past through the medium of local historiography, where we can view these issues in the relatively restricted world of individual city-states, we can (...) gain a clearer insight into how different versions of the past and different constructions of time were offered to the community for approval. In this way, the citizens were able to negotiate time past and indeed their own history, and thereby to express their values and aspirations. (shrink)

In a recent paper in this journal, Kosso ([2000]) discussed the observational status of continuous symmetries of physics. While we are in broad agreement with his approach, we disagree with his analysis. In the discussion of the status of gauge symmetry, a set of examples offered by 't Hooft ([1980]) has influenced several philosophers, including Kosso; in all cases the interpretation of the examples is mistaken.

Predicate nominals (e.g., “is a female”) seem to label or categorize their subjects, while their adjectival correlates (e.g., “is female”) merely attribute a property. Predicate nominals also elicit essentializing inferential judgments about inductive potential and stable explanatory membership. Data from psychology and semantics support that this distinction is robust and productive. I argue that while the difference between predicate nominals and predicate adjectives is elided by standard semantic theories, it ought not be. I then develop and defend a psychologically motivated (...) semantic account on which predicate nominals attribute kind membership and trigger a presupposition that underpins our essentialist judgments.

En este artículo examino el problema de si la concepción socrática de la eudaimonia entraña el egoísmo. Esto es, si, según Sócrates, un hombre que actúa teniendo como criterio final su felicidad es un egoísta. Este punto de vista parece entrar en contradicción con lo que pensamos comúnmente acerca de lo que debe decir una teoría moral. Clasifico los intentos que se han hecho por resolver el problema en dos grupos: los formalistas y los sustantivistas, con base en sus objetivos (...) generales. Argumento que la segunda clase de enfoque es más efectiva, puesto que trata de interpretar la teoría de Sócrates como un todo y la hace más coherente. Asume que Sócrates ofrece una teoría de la motivación humana para actuar en la que el agente busca su felicidad, pero otorgando también una función central a la amistad, el amor y la justicia.

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