This paper explains the phenomena that compose the experience of the passage of time and argues that this experience represents the temporal direction of causal processes. The experience of the passage of time comprises several more specific experiences, namely: (1) the experience of continuously advancing to later times; (2) the observation of continuous change, both in the things around us and in ourselves; (3) the feeling of a lack of control over (1) and (2); and (4) the experience of a (...) number of phenomena that we describe as animated, dynamic, or flowing. The experience of passage is a causal process whose function is to promote survival and reproductive success by representing the temporal direction of causal processes (including itself). It does this primarily via the specious present, wherein later content is presented as more vivid than earlier content. The experience of passage is veridical and is compatible with either the B‐theory or the A‐theoretic views of time. (shrink)

B- theorists frequently argue that the A- theoretic views are incompatible with the Special Theory of Relativity (STR) and that this is a problem for the A- theoretic views. however, the B- theory needs to be revised in light of implications of STR. in particular, it follows from STR that some events stand in genuine temporal relations to each other while others do not. Consequently, there isn’t a single temporal order of all events. instead, there are multiple B- series. Some (...) B- theorists defend a view of the passage of time according to which passage is simply temporal succession. This paper argues that, in Minkowski spacetime, time passes in each of the multiple B- series, but there is no passage spanning across all events because some events stand in no genuine temporal relations to each other.

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)

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)

We argue that recent empirical findings and theoretical models shed new light on the nature of attention. According to the resulting amplification view, attentional phenomena can be unified at the neural level as the consequence of the amplification of certain input signals of attention-independent perceptual computations. This way of identifying the core realizer of attention evades standard criticisms often raised against sub-personal accounts of attention. Moreover, this approach also reframes our thinking about the function of attention by shifting the focus (...) from the function of selection to the function of amplification. (shrink)

A tacit assumption in the field of consciousness studies is that the more empirical evidence a theory can explain, the better it fares when weighed against competitors. If one wants to take seriously the potential for empirical evidence to move forward debates in consciousness studies, there is a need to gather, organize, validate, and compare evidence. We present an inference to the best explanation (IBE) process on the basis of empirical support that is applicable in debates between competing theories of (...) consciousness. Our proposed IBE process consists in four steps: Assimilate, Compile, Validate, and Compare. Until now, the vast majority of the work in the field has consisted in gathering empirical evidence for theories i.e., the assimilation step. To illustrate the feasibility of our proposed IBE process, and what it may look like when applied in practice, we deliver a complete collection (the compilation step) of empirical support for the distinction between A-Consciousness and P-Consciousness and the overflow hypothesis. Finally, we offer an example of the validation step, by scrutinizing the interpretation of aphantasics’ performance on retro-cue paradigms offered in the literature in support of the overflow hypothesis. The compilation we deliver here is the first effort in the IBE process, the end result of which — hopefully — will be the ability of the research community to carry out side-by-side comparisons of theories and the empirical phenomena they claim to explain, i.e., the comparison step.

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 we argue that awareness comes in degrees, and we propose a novel multi-factor account that spans both subjective experiences and perceptual representations. At the subjective level, we argue that conscious experiences can be degraded by being fragmented, less salient, too generic, or flash-like. At the representational level, we identify corresponding features of perceptual representations—their availability for working memory, intensity, precision, and stability—and argue that the mechanisms that affect these features are what ultimately modulate the degree of awareness. (...) We conclude the paper by demonstrating why the original interpretations of certain empirical findings that apparently pose problems for our account are, in fact, flawed. (shrink)

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)

The notion of subjective vividness plays a fundamental role in comparing different conscious experiences, yet it is poorly understood and lacks proper definition. Philosophical reflection on this topic is especially scarce. This article proposes a novel account of vividness arguing that its standard operationalisation in psychology conflates two major modality‐general dimensions along which experiences vary—subjective intensity and subjective specificity—which themselves are determined by further modality‐specific factors. The article identifies the neural underpinnings of these factors in the visual domain, demonstrates the (...) unificatory power of the account, and argues that vividness is part of the content of perception.

This paper tracks the commitments of mechanistic explanations focusing on the relation between activities at different levels. It is pointed out that the mechanistic approach is inherently committed to identifying causal connections at higher levels with causal connections at lower levels. For the mechanistic approach to succeed a mechanism as a whole must do the very same thing what its parts organised in a particular way do. The mechanistic approach must also utilise bridge principles connecting different causal terms of different (...) theoretical vocabularies in order to make the identities of causal connections transparent. These general commitments get confronted with two claims made by certain proponents of the mechanistic approach: William Bechtel often argues that within the mechanistic framework it is possible to balance between reducing higher levels and maintaining their autonomy at the same time, whereas, in a recent paper, Craver and Bechtel argue that the mechanistic approach is able to make downward causation intelligible. The paper concludes that the mechanistic approach imbued with identity statements is no better candidate for anchoring higher levels to lower ones while maintaining their autonomy at the same time than standard reductive accounts are, and that what mechanistic explanations are able to do at best is showing that downward causation does not exist.

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.

Experiences that are self-generated and independent of sensory stimulations permeate our whole life. This theme issue examines their similarities and differences, systematizes the literature from an integrative perspective, critically discusses state-of-the-art empirical findings and proposes new theoretical approaches. The aim of the theme issue is to foster interaction between the different disciplines and research directions involved and to explore the prospects of a unificatory account of offline perception in general.

This paper makes and defends four interrelated claims. First: most conscious experiences are complex in the sense that they have discernible constituent structure with discernible parts that can feature as parts of other experiences, and might occur as standalone experiences. Second: complex experiences have simple constituents that have no further discernible parts. Third: the phenomenal quality of having a complex experience is jointly determined by the phenomenal quality of its simple constituents plus the phenomenal structure simple constituents are organised into. (...) And fourth: physical descriptions can convey all the relevant information about the discernible phenomenal structure of conscious experiences. The combination of these four claims tells us that there is no further explanatory gap related to the phenomenal quality of complex experiences given that one is familiar with the phenomenal qualities of the simple parts constituting the complex experience in question, and that it is possible to acquire knowledge about the phenomenal quality of yet unexperienced complex experiences on the basis of previous acquaintances with constituent parts plus structural information. That is, the paper argues for a ‘summation’ model of phenomenal qualities. (shrink)

The present paper surveys the three most prominent accounts in contemporary debates over how sound reduction should be executed. The classical Nagelian model of reduction derives the laws of the target-theory from the laws of the base theory plus some auxiliary premises (so-called bridge laws) connecting the entities of the target and the base theory. The functional model of reduction emphasizes the causal definitions of the target entities referring to their causal relations to base entities. The new-wave model of reduction (...) deduces not the original target theory but an analogous image of it, which remains inside the vocabulary of the base theory. One of the fundamental motivations of both the functional and the new-wave model is to show that bridge laws can be evaded. The present paper argues that bridge laws—in the original Nagelian sense—are inevitable, i.e. that none of these models can evade them. On the one hand, the functional model of reduction needs bridge laws, since its fundamental concept, functionalization, is an inter-theoretical process dealing with entities of two different theories. Theoretical entities of different theories (in a general heterogeneous case) do not have common causal relations, so the functionalization of an entity—without bridge laws—can only be executed in the framework of its own theory. On the other hand, the so-called images of the new-wave account cannot be constructed without the use of bridge laws. These connecting principles are needed to guide the process of deduction within the base theory; without them one would not be able to recognize if the deduced structure was an image of the target theory.

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.

Several prominent debates in biology, such as those surrounding adaptationism, group selection, and punctuated equilibrium, have focused on disagreements about the relative importance of a cause in producing a phenomenon of interest. Some philosophers, such as John Beatty have expressed scepticism about the scientific value of engaging in these controversies, and Karen Kovaka has suggested that their value might be limited. In this paper, I challenge that scepticism by giving a novel analysis of relative significance controversies, showing that there are (...) three forms they can take. I argue that these controversies can have significant epistemic upshots, in that they help scientists form predictions about new instances of the phenomenon of interest. Finally, using two historical examples, I show how engaging in these controversies can improve our understanding of causal relationships. (shrink)

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.

We argue that pre-cueing studies show that perception is cognitively penetrated via mental imagery. It is important to be clear about the relation between attention and mental imagery here. We do not want to question the role of attention in pre-cueing studies. After all, it is attention that is being pre-cued. The pre-cue draws attention to certain features, which via top-down connections induces mental imagery for the pre-cued properties, which, then, after stimulus-presentation, interacts with and influences the online computations that (...) process stimulus features. That is, what mediates the cognitive penetration of perceptual processing is not pre-cued attention, but cue-induced mental imagery. (shrink)

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

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.

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.

Traditionally, dream research focuses on accounting for typical psychological features of dream experiences characteristic of different sleep stages in terms of the global physiological features of the sleep stages in question. However, as subtle differences got into the forefront of enquiry, as, for example, in questions concerning between-stage similarities and within-stage differences of mentations, this methodology became insufficient. What recent findings and theoretical developments suggest is that understanding mental activity during sleep requires studying the fine-grained characteristics of the phenomenal features (...) of individual dreams, which, in turn, demands identifying specific neural processes that might underlie different characteristics of the experiences, and tracking their changes not just between but also within standard sleep stages. The paper argues that such a shift of focus from describing global stages to understanding the significance of local changes results in a true paradigm shift in dream research that can break away from the tradition of thinking about sleep mentation in terms of discrete categories, and offers a novel way of looking at dreams as forming a multidimensional continuum.

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.

Katherine Clarke explores three authors who wrote about the rise of the Roman Empire - Polybius, Posidonius, and Strabo. She examines the overlap between geography and history in their work, and considers how pre-existing traditions were used but transformed in order to describe the new world of Rome.

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.

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)

The mechanistic framework traditionally comes bundled with a multi-level view. Some ascribe ontological weight to these levels, whereas others claim that characterising a higher-level entity and the corresponding lower-level mechanism are only different descriptions of the same thing. The goal of this paper is to develop a consistent metaphysical picture that can underly the latter position. According to this flat view, wholes and their parts are embedded in the same network of interacting units. The flat view preserves the original virtues (...) of the mechanistic approach and is able to avoid the problems associated with the multi-level view. (shrink)

Scientific researchers welcome disagreement as a way of furthering epistemic aims. Religious communities, by contrast, tend to regard it as a potential threat to their beliefs. But I argue that religious disagreement can help achieve religious epistemic aims. I do not argue this by comparing science and religion, however. For scientific hypotheses are ideally held with a scholarly neutrality, and my aim is to persuade those who arecommittedto religious beliefs that religious disagreement can be epistemically beneficial for them too.
