This paper aims to identify the key characteristics of model organisms that make them a specific type of model within the contemporary life sciences: in particular, we argue that the term “model organism” does not apply to all organisms used for the purposes of experimental research. We explore the differences between experimental and model organisms in terms of their material and epistemic features, and argue that it is essential to distinguish between their representational scope and representational target. We also examine (...) the characteristics of the communities who use these two types of models, including their research goals, disciplinary affiliations, and preferred practices to show how these have contributed to the conceptualization of a model organism. We conclude that model organisms are a specific subgroup of organisms that have been standardized to fit an integrative and comparative mode of research, and that it must be clearly distinguished from the broader class of experimental organisms. In addition, we argue that model organisms are the key components of a unique and distinctively biological way of doing research using models.Keywords: Experimental organism; Genetics; Model organism; Modeling; Philosophy of biology; Representation.

Epistemologists of testimony have focused almost exclusively on the epistemic dynamics of simple testimony. We do sometimes testify by ways of simple, single sentence assertions. But much of our testimony is narratively structured. I argue that narrative testimony gives rise to a form of epistemic dependence that is far richer and more far reaching than the epistemic dependence characteristic of simple testimony.

Our aesthetic judgments are embedded in and shaped by unjust social orders. But can our aesthetic judgments themselves—“this is beautiful; that is not”—be unjust? This article argues that they can. Admitting that this is so does not require us to be unduly revisionary with respect to our concept of justice. Rather, the thought that aesthetic judgments are unjust flows naturally from familiar egalitarian constraints.

This book is about the norms of the speech act of assertion. This is a topic of lively contemporary debate primarily carried out in epistemology and philosophy of language. Suppose that you ask me what time an upcoming meeting starts, and I say, “4 p.m.” I’ve just asserted that the meeting starts at 4 p.m. Whenever we make claims like this, we’re asserting. The central question here is whether we need to know what we say, and, relatedly, whether what we (...) assert must be true. If the meeting is really at 3:30 p.m., you’ll be late, and probably rather upset that I told you the wrong time. In some sense, it seems like I’m on the hook for having said something false. This sense that I’ve done something wrong suggests that there are certain standards of evaluating assertions: a way of distinguishing between good and bad, appropriate and inappropriate. We call these standards norms. And so the debate about what, if any, norms govern the linguistic practice of assertion is known as the norms of assertion debate. When one’s assertion satisfies the norm, we say that the assertion is warranted. -/- Various philosophers have typically focused their views of the norms of assertion on articulating the level of epistemic support required for properly asserting. Some argue, for example, that one must know what one asserts. Others argue that one merely needs to justifiably believe what one asserts–an epistemic standing weaker than knowledge. The purpose of this book is to defend what I propose as the central norm governing our practice of assertion, which I call the Supportive Reasons Norm. Here’s what it looks like: -/- One may assert that p only if: One has supportive reasons for p, The relevant conventional and pragmatic elements of the context are present, and One asserts that p at least in part because the assertion that p satisfies and. -/- In rough outline, the standards for warrantedly asserting shift with changes in context, although knowledge is never required for warrantedly asserting. In fact, in some special contexts, speakers may warrantedly lie. This latter feature particularly sets apart my view from others in the debate. This also means that truth, knowledge, and even belief aren’t necessary conditions for warrantedly asserting. (shrink)

Increasingly, metaphors are the target of political critique: Jewish groups condemn Holocaust imagery; mental health organizations, the metaphorical exploitation of psychosis; and feminists, “rape metaphors.” I develop a novel model for making sense of such critiques of metaphor.

Hate speech and misinformation are rife. How to respond? Counterspeech proposals say: with more and better speech. This paper considers the treatment of counterspeech in Maxime Lepoutre’s Democratic Speech In Divided Times. Lepoutre provides a nuanced defence of counterspeech. Some counterspeech, he grants, is flawed. But, he says: counterspeech can be debugged. Once we understand why counterspeech fails – when fail it does – we can engineer more effective counterspeech strategies. Lepoutre argues that the failures of counterspeech can be theorised (...) using the ideology of salience. Negative counterspeech fails because it reinforces the salience of the very ideas or associations that it contests. His solution? Positive counterspeech – a form of counterspeech which avoids the salience trap. I argue that the salience paradigm is ill-suited to theorise the failures of counterspeech. I suggest some alternatives. Further, I show that these alternative paradigms make importantly different practical recommendations – recommendations concerning how we ought to engineer our counterspeech – from those issued by the salience paradigm.

is a term introduced by Ian Hacking to refer to the kinds of people—child abusers, pregnant teenagers, the unemployed—studied by the human sciences. Hacking argues that classifying and describing human kinds results in feedback, which alters the very kinds under study. This feedback results in human kinds having histories totally unlike those of natural kinds (such as gold, electrons and tigers), leading Hacking to conclude that human kinds are radically unlike natural kinds. Here I argue that Hacking's argument fails and (...) that he has not demonstrated that human kinds cannot be natural kinds.

We argue that individual and institutional caregivers have a defeasible moral duty to provide dependent children with plant-based diets and related education. Notably, our three arguments for this claim do not presuppose any general duty of veganism. Instead, they are grounded in widely shared beliefs about children’s interests and caregivers’ responsibilities, as well as recent empirical research relevant to children’s moral development, autonomy development, and physical health. Together, these arguments constitute a strong cumulative case against inculcating in children the dietary (...) practice of regularly eating meat (and other animal products) — a practice we call ‘carnism’.

This article discusses recent theories of the meaning of generics. The discussion is centred on how the theories differ in their approach to addressing the primary difficulty in providing a theory of generic meaning: The notoriously complex ways in which the truth conditions of generics seem to vary. In addition, the article summarizes considerations for and against each theory.

In this paper I discuss the interrelated topics of stereotype threat and attributional ambiguity as they relate to gender and gender identity. The former has become an emerging topic in feminist philosophy and has spawned a tremendous amount of research in social psychology and elsewhere. But the discussion, at least in how it connects to gender, is incomplete: the focus is only on cisgender women and their experiences. By considering trans women's experiences of stereotype threat and attributional ambiguity, we gain (...) a deeper understanding of the phenomena and their problematic effects. (shrink)

Much recent philosophical work argues that power constrains speech—pornography silences women, testimonial injustice thwarts a speaker’s transmission of knowledge, bias distorts the performative force of subordinated speech. Though the constraints that power places on speech are serious, power also enables some speech. Power doesn’t just keep us from speaking—it also makes us speak. In this paper I explore how power produces, rather than constrains, speech. I discuss a kind of speech I call extracted speech: speech that is unjustly elicited from (...) an agent. I discuss examples of coerced confession, intimidated “consent,” and mandatory self-disclosure as instances of extracted speech, and theorize a bit about what significance this speech has more generally for philosophy of language and political philosophy.

Lucidly and persuasively written, this book will be an invaluable resource for students and scholars seeking to understand Irigaray's original contribution to philosophical and feminist thought.

This paper is about the relevance of attitude-ascriptions to debates about singular thought. It examines a methodology (common to early acquaintance theorists [Kaplan 1968] and recent critics of acquaintance [Hawthorne and Manley 2012], which assumes that the behaviour of ascriptions can be used to draw conclusions about singular thought. Although many theorists (e.g. [Recanati 2012]) reject this methodology, the literature lacks a detailed examination of its implications and the challenges faced by proponents and critics. I isolate an assumption of the (...) methodology, which I call the tracking assumption: that an attitude-ascription which states that s Φ's that P is true iff s has an attitude, of Φ-ing, which is an entertaining of the content P (with entertain used in a stipulated sense). I argue that the tracking assumption must be rejected, not because it has deflationary consequences, but because it leads to unstable commitments. I also show that there are independent reasons to reject it, because ordinary attitude ascriptions underdetermine even the truth-conditions of the mental-states they ascribe. However, I argue, this does not involve rejecting the claim that attitude-ascriptions express relations between agents and contents. Instead, they state different relations depending on contextual factors other than the nature of the mental-states ascribed. (shrink)

Diagnosing the Diagnostic and Statistical Manual of Mental Disorders (Karnac, 2014) evaluates the latest edition of the D.S.M.The publication of D.S.M-5 in 2013 brought many changes. Diagnosing the Diagnostic and Statistical Manual of Mental Disorders asks whether the D.S.M.-5 classifies the right people in the right way. It is aimed at patients, mental health professionals, and academics with an interest in mental health. Issues addressed include: How is the D.S.M. affected by financial links with the pharmaceutical industry? To what extent (...) were and should patients involved in revising the classification? How are diagnoses added to the D.S.M.? Does medicalization threaten the idea that anyone is normal? What happens when changes to diagnostic criteria mean that people lose their diagnoses? How important will the D.S.M. be in the future? (shrink)

In two posthumously published essays, ‘History of Astronomy’ and ‘Of the Nature of that Imitation which takes place in what are called The Imitative Arts’, Adam Smith suggests provocatively that philosophy is an ‘art of imagination’ and that we take the same ‘very high intellectual pleasure’ in appreciating systematic scientific theories and in listening to musical ‘systems’, i.e., complex works of non-programmatic instrumental music. In this paper, I reconstruct the view of imagination, as the cognitive faculty primarily responsible for perception (...) and appreciation of such ‘systems’, that undergirds these claims, and argue that it is to be understood as aiming at ideal ends – in the first instance, at beauty or an order among variety (systematicity). Smith thus offers a distinctive view of aesthetic imagination, as neither freely playing nor imitative (two common views of imagination both in his time and ours) but rather as aiming at, and progressively realizing non-rational norms of order (again, at least in the first instance, an ideal of beauty).

Within the rough ground that is the field of education there is a complex web of ethical obligations: to prepare our students for their future work; to be ethical as educators in our conduct and teaching; to the ethical principles embedded in the contexts in which we work; and given the Southern context of this work, the ethical obligations we have to this land and its First Peoples. We put out a call to colleagues whose work has been concerned with (...) the pedagogies of professional ethics, the ethical burdens of institutional injustice, and the application of ethical theory to education’s applied fields. In the responses we received it can be seen that ethical concerns in education are broad ranging, covering terrain varying from the preparation of preservice teachers, ethics in higher education, early childhood and care, educational leadership, relational and communicative ethics. Perhaps it could also be argued that this paper demonstrates Gibbon’s observation that ‘Assumptions about the particularity of this time as new and ripe with opportunity to make a difference through philosophy of education are not new and there’s much to learn from the persistence of wanting to imagine that they are’. However, while the field of ethics is perennially concerned with human relations and pedagogical interventions to improve these, the responses collected here show that educational ethics is far from static. Educational ethics is a field that continues to develop in response to changing contexts. (shrink)

The standard view amongst philosophers of language and linguists is that the logical form of generics is quantificational and contains a covert, unpronounced quantifier expression Gen. Recently, some theorists have begun to question the standard view and rekindle the competing proposal, that generics are a species of kind-predication. These theorists offer some forceful objections to the standard view, and new strategies for dealing with the abundance of linguistic evidence in favour of the standard view. I respond to these objections and (...) show that their strategies fail. I offer a novel argument in favour of the standard view that I call the binder argument. The upshot of this argument is that if one rejects the existence of Gen, then one is committed to rejecting the existence of covert structure in general. (shrink)

A thesis I call the name-based singular thought thesis is part of orthodoxy in contemporary philosophy of mind and language: it holds that taking part in communication involving a proper name puts one in a position to entertain singular thoughts about the name’s referent. I argue, first, that proponents of the NBT thesis have failed to explain the phenomenon of name-based singular thoughts, leaving it mysterious how name-use enables singular thoughts. Second, by outlining the reasoning that makes the NBT thesis (...) seem compelling and showing how it can be resisted, I argue that giving up the NBT thesis is not a cost, but rather a benefit. I do this by providing an expanded conception of understanding for communication involving names, which sheds light on the nature of communication involving names and the structure of name-using practices.

This paper attributes to Nietzsche a theory of cultural development according to which pyramid societies—steeply hierarchical societies following a unified morality—systematically alternate with motley societies, which emerge when pyramid societies encounter other cultures or allow their strict mores to relax. Motley societies contain multiple value systems due to individual innovation or intercultural contact, and are less stringent in dictating individuals' roles. Consequently, many people are torn between incompatible values and lack direction, so they are drawn to a morality of mediocrity, (...) which offers the modest goals of comfort and conformity. However, the need to mediate between conflicting values also tends to yield exceptional individuals who create new values, and can reshape the society into a new pyramid society governed by those values. I argue that Nietzsche favors neither type of society at the expense of the other, but believes the alternation itself is valuable: a pyramid society develops a value system to its full potential; then, when it encounters alternative values, the extraordinary individuals in the resulting motley society synthesize the competing systems into a fuller vision of human flourishing.

It is widely supposed that the scientists in any field use identical standards for evaluating theories. Without such unity of standards, consensus about scientific theories is supposedly unintelligible. However, the hypothesis of uniform standards can explain neither scientific disagreement nor scientific innovation. This paper seeks to show how the presumption of divergent standards (when linked to a hypothesis of dominance) can explain agreement, disagreement and innovation. By way of illustrating how a rational community with divergent standards can encourage innovation and (...) eventually reach consensus, recent developments in geophysics are discussed at some length.

This essay takes up two questions. First, what does it mean to say that someone creates her own luck? At least colloquially speaking, luck is conceived as something out of an agent's control. So how could an agent increase or decrease the likelihood that she'll be lucky? Building on some recent work on the metaphysics of luck, the essay argues that there is a sense in which agents can create their own luck because people with more skill tend to have (...) more opportunities to benefit from luck. Second, what implications does this conception of luck have for related topics such as how we evaluate performances (like shooting an arrow), including coming to know something? The ubiquitous presence of luck in our actions is often underappreciated. The essay argues that when we combine an expected outcomes view of luck with a counterfactual view of causation, the distinction between environmental and intervening veritic luck seems to disappear. We need a more nuanced view of how luck sometimes undermines credit for success in agents' actions. The upshot of this view is that while luck may undermine the creditworthiness of an agent's success, it only partially undermines creditworthiness. (shrink)

The DSM is the main classification of mental disorders used by psychiatrists in the United States and, increasingly, around the world. Although widely used, the DSM has come in for fierce criticism, with many commentators believing it to be conceptually flawed in a variety of ways. This paper assesses some of these philosophical worries. The first half of the paper asks whether the project of constructing a classification of mental disorders that ‘cuts nature at the joints’ makes sense. What is (...) mental disorder? Are types of mental disorder natural kinds (that is, are the distinctions between them objective and of fundamental theoretical importance, as are, say, the distinctions between the chemical elements)? The second half of the paper addresses epistemic worries. Even if types of mental disorder are natural kinds there may be reason to doubt that the DSM will come to reflect their natural structure. In particular, I examine the extent to which the DSM is theory-laden, and look at how it has been shaped by social and financial factors. Ultimately, I conclude that although the DSM is of immense practical importance it is not likely to become the best possible classification of mental disorders. (shrink)

A new reading of Plato's account of conventionalism about names in the Cratylus. It argues that Hermogenes' position, according to which a name is whatever anybody 'sets down' as one, does not have the counterintuitive consequences usually claimed. At the same time, Plato's treatment of conventionalism needs to be related to his treatment of formally similar positions in ethics and politics. Plato is committed to standards of objective natural correctness in all such areas, despite the problematic consequences which, as he (...) himself shows, arise in the case of language. (shrink)

Although cases are central to the epistemic practices utilized within clinical medicine, they appear to be limited in their ability to provide evidence about causal relations because they provide detailed accounts of particular patients without explicit filtering of those attributes most likely to be relevant for explaining the phenomena observed. This paper uses a series of recent case reports to explore the role of cases in casual attribution in medical diagnosis. It is argued that cases are brought together by practitioners (...) to generate causal attributions and testable predictions using a manipulability view of causation. (shrink)

The lottery paradox plays an important role in arguments for various norms of assertion. Why is it that, prior to information on the results of a draw, assertions such as, “My ticket lost,” seem inappropriate? This paper is composed of two projects. First, I articulate a number of problems arising from Timothy Williamson’s analysis of the lottery paradox. Second, I propose a relevant alternatives theory, which I call the Non-Destabilizing Alternatives Theory , that better explains the pathology of asserting lottery (...) propositions, while permitting assertions of what I call fallible propositions such as, “My car is in the driveway.” Le paradoxe de la loterie joue un rôle important dans l’argumentation visant à défendre diverses normes de l’assertion. Comment se fait-il que, avant que les résultats d’un tirage soient connus, des assertions comme «Mon billet a perdu» semblent inappropriées? Cet article se compose de deux projets. Premièrement, je relève certains problèmes issus de l’analyse du paradoxe de la loterie par Timothy Williamson. Deuxièmement, je propose une théorie des alternatives pertinentes que j’appelle la «théorie des alternatives non-déstabilisantes» , et qui explique d’une meilleure façon la pathologie de l’assertion de propositions concernant la loterie, tout en permettant des assertions faillibles, telles que «Ma voiture est dans l’entrée».

Hume's position in ethics, which is based on his empiricist theory of the mind, is best known for asserting four theses: (1) Reason alone cannot be a motive to the will, but rather is the slave of the passions (see Section 3) (2) Moral distinctions are not derived from reason (see Section 4). (3) Moral distinctions are derived from the moral sentiments: feelings of approval (esteem, praise) and disapproval (blame) felt by spectators who contemplate a character trait or action (see (...) Section 7). (4) While some virtues and vices are natural (see Section 13), others, including justice, are artificial (see Section 9). There is heated debate about what Hume intends by each of these theses and how he argues for them. He articulates and defends them within the broader context of his metaethics and his ethic of virtue and vice. Hume's main ethical writings are Book 3 of his Treatise of Human Nature, Of Morals (which builds on Book 2, Of the Passions), his Enquiry concerning the Principles of Morals, and some of his Essays. In part the moral Enquiry simply recasts central ideas from the moral part of the Treatise in a more accessible style; but there are important differences. The ethical positions and arguments of the Treatise are set out below, noting where the moral Enquiry agrees; differences between the Enquiry and the Treatise are discussed afterwards. (shrink)

I present and evaluate Johann Gottfried Herder's criticisms of Kant's account of the sublime and Herder's own theory of the sublime, as presented in his work, Kalligone. Herder's account and criticisms ought to be taken seriously, I argue, as (respectively) a non-reductive, naturalist aesthetics of the sublime, and as illuminating the metaphysical, moral, and political presuppositions underlying Kant's (and Burke's) accounts of the sublime.

Many philosophers today approach important psychological phenomena, such as weakness of the will and moral motivation, using a broadly Humean distinction between beliefs, which aim to represent the world, and desires, which aim to change the world. On this picture, desires provide the ends or goals of action, while beliefs simply tell us how to achieve those ends. In the Republic, Socrates attempts to explain the phenomena using a different distinction: he argues that the human soul or psyche consists in (...) reason, spirit, and appetite. It is initially tempting to assimilate Socrates’ picture to the standard belief ⁄ desire model, and to think that reason’s role in motivating action is restricted to calculating the best means for satisfying spirited and appetitive desires. But this would be a mistake, since Socrates thinks that each element in the soul is capable of setting the ends of action. But then how exactly should we understand these elements? My aim in this essay is to introduce the reader to Plato’s theory of the tripartite psychology. In part 2, I present Socrates’ argument for the claim that the soul has three elements. In part 3, I provide a general characterization of reason, spirit, and appetite, respectively. I then turn to discuss two central interpretive issues. In part 4, I discuss the sense in which Socrates considers the appetitive and spirited elements to be non-rational. And in the final part of the essay, I discuss the issue of how we ought to conceive of the parts of the soul, and more specifically, whether we should think of them as agent-like parts, or in some other way.

By examining first-person descriptions of thought insertion I show that thought insertion is a complex and heterogeneous phenomenon. People experiencing this phenomenon have huge difficulty explaining what it is like due to the bizarre nature of the experience. Through careful analysis of first-person descriptions I identify some of the characteristics of thought insertion. I then briefly examine some of the philosophical literature regarding agency, ownership and thought insertion and conclude that the standard account of the basic characteristics of thought insertion (...) is inadequate when we consider the phenomenon as it is experienced. First person descriptions suggest that thought insertion is characterised by a lack of personal ownership and not simply by a loss of agency or authorship. This is an important factor that should inform research and therapeutic intervention. We cannot hope to arrive at appropriate therapeutic intervention or identify underlying neuronal mechanisms for the experience if we cannot say what the experience actually is. I further suggest that more analysis of first-person description is required for an improved account of the phenomenology of thought insertion. (shrink)

I argue (contra Guyer et al.) that in the Critique of Judgment Kant espouses a formal, intentional theory of pleasure, and reconstruct Kant's arguments that this view can both identify what all pleasures have in common, and differentiate among kinds of pleasure. Through his investigation of aesthetic experience in the Critique of Judgment, I argue, Kant radically departs from his views about pleasure as mere sensation in the Groundwork and the Critique of Practical Reason, and provides a view of pleasure (...) whereby we can understand pleasure itself to be ruled by an a priori principle.

In this article, I compare and evaluate R. D. Laing and A. Esterson’s account of schizophrenia as developed in Sanity, Madness and the Family, social models of disability, and accounts of extended mental disorder. These accounts claim that some putative disorders should not be thought of as reflecting biological or psychological dysfunction within the afflicted individual, but instead as external problems. In this article, I consider the grounds on which such claims might be supported. I argue that problems should not (...) be located within an individual putative patient in cases where there is some acceptable test environment in which there is no problem. A number of cases where such an argument can show that there is no internal disorder are discussed. I argue, however, that Laing and Esterson’s argument—that schizophrenia is not within diagnosed patients—does not work. The problem with their argument is that they fail to show that the diagnosed women in their study function adequately in any environment. (shrink)

Paradigmatically, natural kinds are the kinds of thing or stuff that are classified by the natural sciences. The periodic table provides perhaps the best example of the potential importance of natural kinds for science. In the philosophy of psychiatry, debates over whether mental disorders can be natural kinds emerge because kinds of mental disorder are manifestly different from chemical kinds in various ways. While chemical kinds are precise, psychiatric kinds are fuzzy. While chemical kinds are objective, the identification of psychiatric (...) kinds is value-laden. Psychiatric classification involves classifying people, and unlike chemical elements, those people can respond to being classified in various ways. This chapter goes through these differences, one-by-one, and argues that despite them, mental disorders may be natural kinds. (shrink)

Background International collaborators face challenges in the design and implementation of ethical biomedical research. Evaluating community understanding of research and processes like informed consent may enable researchers to better protect research participants in a particular setting; however, there exist few studies examining community perspectives in health research, particularly in resource-limited settings, or strategies for engaging the community in research processes. Our goal was to inform ethical research practice in a biomedical research setting in western Kenya and similar resource-limited settings. Methods (...) We sought to use mabaraza , traditional East African community assemblies, in a qualitative study to understand community perspectives on biomedical research and informed consent within a collaborative, multinational research network in western Kenya. Analyses included manual, progressive coding of transcripts from mabaraza to identify emerging central concepts. Results Our findings from two mabaraza with 108 community members revealed that, while participants understood some principles of biomedical research, they emphasized perceived benefits from participation in research over potential risks. Many community members equated health research with HIV testing or care, which may be explained in part by the setting of this particular study. In addition to valuing informed consent as understanding and accepting a role in research activities, participants endorsed an increased role for the community in making decisions about research participation, especially in the case of children, through a process of community consent. Conclusions Our study suggests that international biomedical research must account for community understanding of research and informed consent, particularly when involving children. Moreover, traditional community forums, such as mabaraza in East Africa, can be used effectively to gather these data and may serve as a forum to further engage communities in community consent and other aspects of research.

The so-called "biometric-Mendelian controversy" has received much attention from science studies scholars. This paper focuses on one scientist involved in this debate, Arthur Dukinfield Darbishire, who performed a series of hybridization experiments with mice beginning in 1901. Previous historical work on Darbishire's experiments and his later attempt to reconcile Mendelian and biometric views describe Darbishire as eventually being "converted" to Mendelism. I provide a new analysis of this episode in the context of Darbishire's experimental results, his underlying epistemology, and his (...) influence on the broader debate surrounding the rediscovery and acceptance of Mendelism. I investigate various historiographical issues raised by this episode in order to reflect on the idea of "conversion" to a scientific theory. Darbishire was an influential figure who resisted strong forces compelling him to convert prematurely due to his requirements that the new theory account for particularly important anomalous facts and answer the most pressing questions in the field.

Tragic moral conflicts are situations from within which whatever one does—including abstaining from action—will be seriously wrong; even the overall right decision involves violating a moral responsibility. This article offers an account of recovery predicaments, a particular kind of tragic conflict that characterizes the current extinction crisis.

Recognizing the harm of (...) acting from within recovery conflicts adds force to appeals for interrogating and dismantling the systems of thinking, valuing, and acting that bring species to the brink of extinction.
