I outline a number of parallels between trust and distrust, emphasising the significance of situations in which both trust and distrust would be an imposition upon the (dis)trustee. I develop an account of both trust and distrust in terms of commitment, and argue that this enables us to understand the nature of trustworthiness. Note that this article is available open access on the journal website.

What kind of entity is a committee, a book group or a band? I argue that committees and other such social groups are concrete, composite particulars, having ordinary human beings amongst their parts. So the committee members are literally parts of the committee. This mereological view of social groups was popular several decades ago, but fell out of favour following influential objections from David-Hillel Ruben. But recent years have seen a tidal wave of work in metaphysics, including the metaphysics of (...) parts and wholes. We now have the resources to rehabilitate the mereological view of social groups. I show how this can be done, and why we should bother. (shrink)

We articulate a view of natural kinds as complex universals. We do not attempt to argue for the existence of universals. Instead, we argue that, given the existence of universals, and of natural kinds, the latter can be understood in terms of the former, and that this provides a rich, flexible framework within which to discuss issues of indeterminacy, essentialism, induction, and reduction. Along the way, we develop a 'problem of the many' for universals.

Analytic metaphysics is in resurgence; there is renewed and vigorous interest in topics such as time, causation, persistence, parthood and possible worlds. We who share this interest often pay lip-service to the idea that metaphysics should be informed by modern science; some take this duty very seriously.2 But there is also a widespread suspicion that science cannot really contribute to metaphysics, and that scientific findings grossly underdetermine metaphysical claims. For some, this prompts the thought ‘so much the worse for metaphysics’; (...) others mutter ‘so much the worse for science’. (shrink)

Much of what we learn from talking and listening does not qualify as testimonial knowledge: we can learn a great deal from other people without simply accepting what they say as being true. In this article, I examine the ways in which we acquire skills or knowledge how from our interactions with other people, and I discuss whether there is a useful notion of testimonial knowledge how.Keywords: Knowledge how; Practical knowledge; Tacit knowledge; Testimony; Skills; Assertion.

Appeals to intersectionality serve to remind us that social categories like race and gender cannot be adequately understood independently from each other. But what, exactly, is the intersectional thesis a thesis about? Answers to this question are remarkably diverse. Intersectionality is variously understood as a claim about the nature of social kinds, oppression, or experience ; about the limits of antidiscrimination law or identity politics ; or about the importance of fuzzy sets, multifactor analysis, or causal modeling in social science.

Vague existence can seem like the worst kind of vagueness in the world, or seem to be an entirely unintelligible notion. This bad reputation is based upon the rumour that if there is vague existence then there are non-existent objects. But the rumour is false: the modest brand of vague existence entailed by certain metaphysical theories of composition does not deserve its bad reputation.

People are described as suffering from impostor syndrome when they feel that their external markers of success are unwarranted, and fear being revealed as a fraud. Impostor syndrome is commonly framed as a troubling individual pathology, to be overcome through self-help strategies or therapy. But in many situations an individual’s impostor attitudes can be epistemically justified, even if they are factually mistaken: hostile social environments can create epistemic obstacles to self-knowledge. The concept of impostor syndrome prevalent in popular culture needs (...) greater critical scrutiny, as does its source, the concept of impostor phenomenon which features in psychological research.

If the property _being a methane molecule_ is a universal, then it is a structural universal: objects instantiate _being a methane molecule_ just in case they have the right sorts of proper parts arranged in the right sort of way. Lewis argued that there can be no satisfactory account of structural universals; in this paper I provide a satisfactory account.

I argue that, despite van Inwagen’s pessimism about the task, it is worth looking for answers to his General Composition Question. Such answers or ‘principles of composition’ tell us about the relationship between an object and its parts. I compare principles of composition with criteria of identity, arguing that, just as different sorts of thing satisfy different criteria of identity, they may satisfy different principles of composition. Variety in criteria of identity is not taken to reflect ontological variety in the (...) identity relation; I discuss whether variety in principles of composition should be taken to reflect ontological variety in the composition relation.

If we are sympathetic to the project of naturalising metaphysics, how should we approach the metaphysics of the social world? What role can the social sciences play in metaphysical investigation? In the light of these questions, this paper examines three possible approaches to social metaphysics: inference to the best explanation from current social science, conceptual analysis, and Haslanger-inspired ameliorative projects.

Gatekeeping, or determining membership of your group, is crucial to science: the moniker ‘scientific’ is a stamp of epistemic quality or even authority. But gatekeeping in science is fraught with dangers. Gatekeepers must exclude bad science, science fraud and pseudoscience, while including the disagreeing viewpoints on which science thrives. This is a difficult tightrope, not least because gatekeeping is a human matter and can be influenced by biases such as groupthink. After spelling out these general tensions around gatekeeping in science, (...) we shed light on them with a case study from psychology. This concerns whether academic psychologists rightly or wrongly classify the applied-psychology framework of NLP (‘neuro-linguistic programming’) as unscientific and even pseudoscientific. This example of gatekeeping is particularly instructive because both the NLP community and the psychology community, we argue, make legitimate but also illegitimate moves. This case gives rise to several general insights about gatekeeping in science more generally. (shrink)

ABSTRACTThe Ant Trap is a terrific book, which opens up new opportunities to use philosophical methods in the social realm, by drawing on the tools and techniques of contemporary metaphysics. Epstein uses concepts of dependence, constitution, and grounding, of parts and whole, of membership and kindhood, both to clarify existing accounts of social reality and to develop an account of his own. Whilst I admire the general strategy, I take issue with some aspects of Epstein’s implementation, notably his distinction between (...) grounding and anchoring. I recommend that he give up this distinction, which is not crucial to his project. (shrink)

Conspiracy theorists believe that powerful agents are conspiring to achieve their nefarious aims and also to orchestrate a cover-up. People who suffer from impostor syndrome believe that they are not talented enough for the professional positions they find themselves in, and that they risk being revealed as inadequate. These are quite different outlooks on reality, and there is no reason to think that they are mutually reinforcing. Nevertheless, there are intriguing parallels between the patterns of trust and distrust which underpin (...) both conspiracy theorising and impostor thinking. In both cases subjects distrust standard sources of information, instead regarding themselves as especially insightful into the underlying facts of the matter. In both cases, seemingly-anomalous data takes on special significance. And in both cases, the content of belief dictates the epistemic behaviour of the believer. This paper explores these parallels, to suggest new avenues of research into both conspiracy theorising and impostor syndrome, including questions about whether impostor syndrome inevitably involves a personal failure of rationality, and issues about how, if at all, it is possible to convince others to abandon either conspiracy theories or impostor attitudes.

I claim that, if persisting objects have temporal parts, then there are non-supervenient relations between those temporal parts. These are relations which are not determined by intrinsic properties of the temporal parts. I use the Kripke-Armstrong 'rotating homogeneous disc' argument in order to establish this claim, and in doing so I defend and develop that argument. This involves a discussion of instantaneous velocity, and of the causes and effects of rotation. Finally, I compare alternative responses to the rotating disc argument, (...) and consider the implications of my arguments for the doctrines of Humean Supervenience and unrestricted mereology.

This is a short response to a paper by Trenton Merricks in which he argues against the following doctrine: Microphysical Supervenience (MS) Necessarily, if atoms A1 through An compose an object that exemplifies intrinsic qualitative properties Q1 through Qn, then atoms like A1 through An (in all their respective intrinsic qualitative properties), related to one another by all the same restricted atom-to-atom relations as A1 through An, compose an object that exemplifies Q1 through Qn.

This chapter explores the connections between David Lewis's perdurance theory and his Humean supervenience, arguing that his influential argument about temporary intrinsics is best seen in this light. It presents domestic dispute within the anti‐endurantist camp and analyzes the following questions: why does Lewis identify ordinary objects with world‐bound parts of transworld objects, but not with time‐bound parts of transtemporal objects? Given that Lewis is a counterpart theorist about modality, why isn't he a stage theorist about persistence? Humean supervenience in (...) isolation does not entail perdurance theory, even for the actual world. Lewis's treatment of temporary intrinsics in On the Plurality of Worlds forms part of a discussion of both persistence and its modal analogue, for which there is no neutral term. Perdurance theory is challenged by the stage theory of persistence, which identifies ordinary objects with brief stages instead of transtemporal sums of those stages. (shrink)

In his paper in the same volume, Sider argues that, of maximalism and quantifier variance, the latter promises to let us make better sense of neo-Fregeanism. I argue that neo-Fregeans should, and seemingly do, reject quantifier variance. If they must choose between these two options, they should choose maximalism.

In his Material Beings, Peter van Inwagen distinguishes two questions about parthood. What are the conditions necessary and sufficient for some things jointly to compose a whole? What are the conditions necessary and sufficient for a thing to have proper parts? The first of these, the Special Composition Question (SCQ), has been widely discussed, and David Lewis has argued that an important constraint on any answer to the SCQ is that it should not permit borderline cases of composition. This is (...) a far-reaching claim, since many plausible-seeming accounts of composition do permit borderline cases. Ned Markosian has recently directed our attention to the second, the neglected Inverse Special Composition Question (ISCQ). I will argue that those who accept Lewis’s constraint on answers to the SCQ should accept an analogous constraint on answers to the ISCQ, and I will discuss the effects of such a constraint.

Roughly speaking, perdurantism is the view that ordinary objects persist through time by having temporal parts, whilst endurantism is the view that they persist by being wholly present at different times. (Speaking less roughly will be important later.) It is often thought that perdurantists have an advantage over endurantists when dealing with objects which appear to coincide temporarily: lumps, statues, cats, tail-complements, bisected brains, repaired ships, and the like. Some cases – personal fission, for example – seem to involve temporary (...) coincidence between objects of the same kind. Other cases – a cat and its flesh, a statue and its lump – seem to involve objects of different kinds. (shrink)

Metaphysics can be used to help us understand the world, and has applications both within philosophy and beyond. Within philosophy, metaphysical questions arise whether we are thinking about ethics, art, religion, or science. Beyond philosophy, there are many areas where metaphysics can be applied. Case studies in this chapter include applied ontology in information science, social ontology in both philosophy and the social sciences, and questions about classification and kinds in psychiatry.

This research article analyses the influence of micro-enterprise managers' perception of their relationship to their environment on the nature of their ethics. We carried out a survey with the head managers of 125 French MEs, providing a large set of primary data. Two types of variables were defined: variables related to the nature and intensity of the relationships between ME managers and their social environment, and variables related to the ethical framework that the managers used. The results of univariate and (...) bivariate analyses show significant statistical relationships between the variables that indicated perceived embeddedness in the community and ethical variables. This result underlines the idea that "communities of ethics" may have an important influence in MEs. (shrink)

Take this banana. It is now yellow, and when I bought it yesterday it was green. How can a single object be both green all over and yellow all over without contradiction? It is, of course, the passage of time which dissolves the contradiction, but how is this possible? How can a banana ripen? These questions raise the problem of change. The problem is sometimes called the problem of temporary intrinsics, but, as I shall explain below, this emphasis on intrinsic (...) properties is misleading. For my more recent thoughts in this area, please see my 'David Lewis on Persistence' (2015). (shrink)

Nature and Narrative is the launch volume in a new series of books entitled International Perspectives in Philosophy and Psychiatry. The series will aim to build links between the sciences and humanities in psychiatry. Our ability to decipher mental disorders depends to a unique extent on both the sciences and the humanities. Science provides insight into the 'causes' of a problem, enabling us to formulate an 'explanation', and the humanities provide insight into its 'meanings' and helps with our 'understanding'. Psychiatry, (...) if it is to develop as a balanced discipline, must draw on input from both of these spheres. Nature (for causes) and Narrative (for meanings) will help define the series as a whole by touching on a range of issues relevant to this 'border country'. With contributions from an international star-studded cast, representing the field of psychiatry, psychology and philosophy, this volume will set the scene for this new interdisciplinary field. This will be of interest to all those with practical experience of mental health issues, whether as providers or as users/consumers of services, as well as to philosophers, social scientists, and bioethicists.

This is a paper, aimed at students, which sets out some issues regarding personal identity over time.

With the knowledge that team work is not always associated with high(er) performance, we draw from the Multi-Level Theory of Psychological Contracts, Person-Environment Fit Theory, and Optimal Distinctiveness Theory to study shared perceptions of psychological contract (PC) breach in relation to shared perceptions of complementary and supplementary fit to explain why some teams perform better than other teams. We collected three repeated survey measures in a sample of 128 respondents across 46 teams. After having made sure that we met all (...) statistical criteria, we aggregated our focal variables to the team-level and analysed our data by means of a longitudinal three-wave autoregressive moderated-mediation model in which each relationship was one-time lag apart. We found that shared perceptions of PC breach were directly negatively related to team output and negatively related to perceived team member effectiveness through a decrease in shared perceptions of supplementary fit. However, we also demonstrated a beneficial process in that shared perceptions of PC breach were positively related to shared perceptions of complementary fit, which in turn were positively related to team output. Moreover, best team output appeared in teams that could combine high shared perceptions of complementary fit with modest to high shared perceptions of supplementary fit. Overall, our findings seem to indicate that in terms of team output there may be a bright side to perceptions of PC breach and that perceived person-team fit may play an important role in this process.

In his 1991 book, Parts of Classes, David Lewis discusses the idea that composition is identity, alongside the idea that mereological overlap is a form of partial identity. But this notion of partial identity does nothing to help Lewis achieve his goals in that book. So why does he mention it? I explore and resolve this puzzle, by comparing Parts of Classes with Lewis's invocation of partial identity in his 1993 paper ‘Many But Almost One’, where he uses it to (...) address Unger's problem of the many. I raise some concerns about this way of thinking of partial identity, but conclude that, for Lewis, it is an important defence against accusations of ontological profligacy. (shrink)

This is a contribution to a symposium on Trenton Merricks' book Truth and Ontology. The symposium includes contributions by Karen Bennett and Kris McDaniel, with précis and replies by Trenton Merricks. I argue that even the very weak truthmaking principle he is willing to endorse is nevertheless useful for some philosophical purposes.

This article draws upon work by Gilles Deleuze, Sanford Meisner, and William Connolly to argue that the practice of acting helps citizens to encounter unsettling circumstances in daily life; respond to and connect with others in more open, interactive ways; and expand the relatively stable repertoire of selves each person cultivates through life. Considering scenes from the films of Anna Magnani, Ronald Reagan, and Joan Crawford, I argue that acting spaces can be sites where an exploration and decentring of subjectivity (...) can proceed and new modes of democratic interaction and togetherness can be enacted.

In lieu of an abstract, here is a brief excerpt of the content:A Prayer for the BabyKatherine J. GoldWe didn’t talk much about religion in medical school. Rightly so, it seemed to me at the time. I didn’t know how or why it would fit in to my patient care other than respecting patients who used their faith as a coping strategy. I was not at all religious and didn’t like the thought of talking about such things with patients. And (...) in my clinical experiences, it rarely came up.When I got to my last year of school, I signed up to work for a month with an obstetrician–gynecologist in her outpatient clinic. I don’t recall how I met her but remember she was respected for her outpatient teaching so it seemed like it would be a good experience to work with her. (I’ll refer to her by a fictional name here.)“Call me Maria,” she told new patients, enveloping them in a warm, supportive style. They did, and I adjusted to her caring approach, shadowing her as we saw patients during pregnancy, those with abnormal uterine bleeding, patients with pelvic pain, others needing pelvic surgeries. It was an odd experience for me, six months pregnant myself, to be seeing other patients during their own pregnancies.One day, about a week in to my rotation, a couple came in together for an appointment two weeks after an early miscarriage. I watched Dr. Copeland (as a student I just couldn’t call my attending by her first name) give them a hug and we sat down. She asked how they were doing and they shared their story, tears flowing as the mother recounted her emotions over the last week and support from their friends. I had the impression that they attended the same church as Dr. Copeland from their conversation. At the end of the visit everyone stood up.“Shall we pray?” Dr. Copeland asked, and they all took hands. I edged back, away from their small circle, uncertain what to do. I had never seen prayer in medical practice and certainly not initiated by the doctor. Not being religious myself, I felt uncomfortable. I didn’t know the protocol. This was not a setting where I knew what to do. So I leaned [End Page 200] quietly against the wall, trying to be unobtrusive, feeling my baby kicking while I watched. All of them bowed their heads and Dr. Copeland said a brief prayer. I watched the mother as her shoulders relaxed. They said “amen” and squeezed hands and hugged one last time. I thought about that interaction for weeks afterwards. I was uncomfortable, but clearly the patients were not. If there were a role for religion in medicine, I reflected, this might be a place for it. It had been accepted by the family without hesitation, so somehow Dr. Copeland knew it would be alright. It had been used in a healing way.There were several other visits where Dr. Copeland prayed with patients. Sometimes she seemed to know them from her church; at other times, I wasn’t sure. But there never seemed to be a misstep—patients never seemed surprised or awkward with her approach. Did they choose her because of shared beliefs? Did she have a reputation of using faith in her practice and patients selected her for this reason? I wasn’t sure. But it was always the same. They would bow their heads and pray. I would stand back a little uncertainly, but the patients were always grateful and appreciative, thanking Maria by her first name as they left.As I spent more time with her, I looked for other ways that faith might impact Dr. Copeland’s practice and asked questions when I thought there might be relevance. I knew from others that she was opposed to abortion, though I never heard her talk about it openly and I was unsure how this might be manifest in her practice. I watched her prescribe birth control (I knew some religious physicians who did not). I watched her send a patient with a second trimester fetal death to the hospital to be induced for delivery. I wondered if someone... (shrink)

There is very little literature on the actual decision-making frameworks used by general practitioners with respect to ethical issues and virtually none on the impact of personal experiences of illness on this. This study aimed to investigate what these frameworks might be and if and how they were altered by doctors’ own illness experience. Twenty general practitioners were recruited, 10 having had a previous serious medical illness and 10 having no such history. They participated in a semi-structured interview, including case (...) vignettes, recorded and analysed using qualitative thematic analysis. Being a patient themselves altered general practitioners’ decision-making by enhancing physician empathy, increasing ease at discussing difficult topics, having a greater willingness to support patient choice and a wider ability to provide a greater diversity of therapeutic strategies, with the role of empathy being the most noticeable difference between the groups. Doctors who had not had a severe personal illnes... (shrink)

The ethics of treating the seriously and critically ill have not been static throughout the ages. Twentieth century medicine has inherited from the nineteenth century a science which places an inappropriate weight on diagnosis over prognosis and management, combined with a seventeenth century duty to prolong life. However other earlier ethical traditions, both Hippocratic and Christian, respected both the limitations of medicine and emphasised the importance of prognosis. This paper outlines some of the historical precedents for the treatment of the (...) critically ill, and also how the current paradigm limits clinical practice and causes ethical tensions. An understanding that other paradigms have been ethically acceptable in the past allows wider consideration and acceptance of alternatives for the future. However future alternatives will also have to address the role of technology, given its importance in this area of medicine. (shrink)
