Lewis's notion of a "natural" property has proved divisive: some have taken to the notion with enthusiasm, while others have been sceptical. However, it is far from obvious what the enthusiasts and the sceptics are disagreeing about. This paper attempts to articulate what is at stake in this debate.

This paper considers how counterfactuals should be evaluated on the assumption that determinism is true. I argue against Lewis's influential view that the actual laws of nature would have been false if something had happened that never actually happened, and in favour of the competing view that history would have been different all the way back. I argue that we can do adequate justice to our ordinary practice of relying on a wide range of historical truths in evaluating counterfactuals by (...) saying that, in typical cases, history would have been only *very slightly* different until shortly before the relevant time. The paper also draws some connections between the puzzle about counterfactuals under determinism and the debate about whether determinism entails that no-one can ever do otherwise than they in fact do.

This paper defends the claim that although ‘Superman is Clark Kent and some people who believe that Superman flies do not believe that Clark Kent flies’ is a logically inconsistent sentence, we can still utter this sentence, while speaking literally, without asserting anything false. The key idea is that the context-sensitivity of attitude reports can be - and often is - resolved in different ways within a single sentence.

This paper is an investigation of the general logic of "identifications", claims such as 'To be a vixen is to be a female fox', 'To be human is to be a rational animal', and 'To be just is to help one's friends and harm one's enemies', many of which are of great importance to philosophers. I advocate understanding such claims as expressing higher-order identity, and discuss a variety of different general laws which they might be thought to obey. [New version: (...) Nov. 4th, 2016].

Seth Yalcin has pointed out some puzzling facts about the behaviour of epistemic modals in certain embedded contexts. For example, conditionals that begin ‘If it is raining and it might not be raining, … ’ sound unacceptable, unlike conditionals that begin ‘If it is raining and I don’t know it, … ’. These facts pose a prima facie problem for an orthodox treatment of epistemic modals as expressing propositions about the knowledge of some contextually specified individual or group. This paper (...) develops an explanation of the puzzling facts about embedding within an orthodox framework. (shrink)

We argue that all comparative expressions in natural language obey a principle that we call Comparability: if x and y are at least as F as themselves, then either x is at least as F as y or y is at least as F as x. This principle has been widely rejected among philosophers, especially by ethicists, and its falsity has been claimed to have important normative implications. We argue that Comparability is needed to explain the goodness of several patterns (...) of inference that seem manifestly valid, that the purported failures of Comparability would have absurd consequences, and that the influential arguments against Comparability are less compelling than they may have initially seemed.

There is a common practice of providing natural-language ‘glosses’ on sentences in the language of higher order logic: for example, the higher-order sentence ∃X(X Socrates) might be glossed using the English sentence ‘Socrates has some property’. It is widely held that such glosses cannot be strictly correct, on the grounds that the word ‘property’ is a noun and thus, if meaningful at all, should be meaningful in the same way as any other noun. Against this view, this paper argues that (...) natural languages feature pervasive type-ambiguity in such a way that the relevant English sentences are in fact semantically equivalent to the higher-order sentences of which they serve as ‘glosses’. It also responds to some objections that have often been taken to be fatal to such type-ambiguity, such as the challenge of accounting for the meaning of ‘mixed disjunctions’ like ‘Either Mars or the property of being red is interesting’.

This three-part chapter explores a higher-order logic we call ‘Classicism’, which extends a minimal classical higher-order logic with further axioms which guarantee that provable coextensiveness is sufficient for identity. The first part presents several different ways of axiomatizing this theory and makes the case for its naturalness. The second part discusses two kinds of extensions of Classicism: some which take the view in the direction of coarseness of grain (whose endpoint is the maximally coarse-grained view that coextensiveness is sufficient for (...) identity), and some which take the view in the direction of fineness of grain (whose endpoint is the maximally fine-grained theory containing all distinctness claims compatible with Classicism). The third part introduces some techniques for constructing models of Classicism, and uses them to prove the consistency of many of the extensions of Classicism introduced in the second part.

We present and discuss a counterexample to the following plausible principle: if you know that a coin is fair, and for all you know it is going to be flipped, then for all you know it will land tails.

We defend the thesis that every necessarily true proposition is always true. Since not every proposition that is always true is necessarily true, our thesis is at odds with theories of modality and time, such as those of Kit Fine and David Kaplan, which posit a fundamental symmetry between modal and tense operators. According to such theories, just as it is a contingent matter what is true at a given time, it is likewise a temporary matter what is true at (...) a given possible world; so a proposition that is now true at all worlds, and thus necessarily true, may yet at some past or future time be false in the actual world, and thus not always true. We reconstruct and criticize several lines of argument in favor of this picture, and then argue against the picture on the grounds that it is inconsistent with certain sorts of contingency in the structure of time.

According to a tradition stemming from Quine and Putnam, we have the same broadly inductive reason for believing in numbers as we have for believing in electrons: certain theories that entail that there are numbers are better, qua explanations of our evidence, than any theories that do not. This paper investigates how modal theories of the form ‘Possibly, the concrete world is just as it in fact is and T’ and ‘Necessarily, if standard mathematics is true and the concrete world (...) is just as it in fact is, then T’ bear on this claim. It concludes that, while analogies with theories that attempt to eliminate unobservable concrete entities provide good reason to regard theories of the former sort as explanatorily bad, this reason does not apply to theories of the latter sort.

In a recent paper, Yoaav Isaacs, Alan Hájek, and John Hawthorne argue for the rational permissibility of "credal imprecision" by appealing to certain propositions associated with non-measurable spatial regions: for example, the proposition that the pointer of a spinner will come to rest within a certain non-measurable set of points on its circumference. This paper rebuts their argument by showing that its premises lead to implausible consequences in cases where one is trying to learn, by making multiple observations, whether a (...) certain outcome is associated with a non-measurable region or a measurable one.

We defend three controversial claims about preference, credence, and choice. First, all agents (not just rational ones) have complete preferences. Second, all agents (again, not just rational ones) have real-valued credences in every proposition in which they are confident to any degree. Third, there is almost always some unique thing we ought to do, want, or believe.

This paper investigates the form a modal realist analysis of possibility and necessity should take. It concludes that according to the best version of modal realism, the notion of a world plays no role in the analysis of modal claims. All contingent claims contain some de re element; the effect of modal operators on these elements is described by a counterpart theory which takes the same form whether the de re reference is to a world or to something else. This (...) fully general counterpart theory can validate orthodox modal logic, including the logic of 'actually'. (shrink)

Mark Johnston (2016, 2017) has argued on ethical grounds against a wide variety of "naturalistic" world views, which imply 'in our close vicinity, there are many persisting things all ontologically on a par, very similar in their features and such that they come into being and cease to exist at various times'—'personites', for short. Johnston argues that if personites exist, their intrinsic properties are compatible with their being people and thus having moral status; but since moral status is an intrinsic (...) matter, this implies that personites enjoy the same kind of moral status as people, a conclusion which leads to various bizarre ethical consequences. In response, we defend the view that although personites exist, they lack moral status, and have intrinsic properties (including modal properties) which no person could have. We also isolate a different argument for the moral status of certain personites, based on the claim that they instantiate properties which 'person' could very easily have expressed; we show how this argument can be resisted by adopting a pluralistic semantics, on which predicates like 'person' and 'being with moral status' express many properties even at the actual world.

This paper is a response to Theodore Sider's book, Writing the Book of the World. It raises some puzzles about Sider's favoured methodology for finding out about naturalness (or 'structure').

David Builes presents a paradox concerning how confident you should be that any given member of an infinite collection of fair coins landed heads, conditional on the information that they were all flipped and only finitely many of them landed heads. We argue that if you should have any conditional credence at all, it should be 1/2.

Timothy Williamson has shown that the B axiom for 'definitely' (α → Δ¬Δ¬α) guarantees that if a sentence is second-order vague in a Kripke model, it is nth order vague for every n. More recently, Anna Mahtani has argued that Williamson's epistemicist theory of vagueness does not support the B axiom, and conjectured that if we consider models in which the “radius of accessibility” varies between different points, we will be able to find sentences that are nth-order vague but (n+1)th-order (...) precise, for any n. This paper bolsters Mahtani's argument, shows her conjecture to be true, and shows that imposing certain further natural constraints on "variable radius" models does not change the situation.

A discussion of a view, defended by Robert Adams and Boris Kment, according to which contingent existence requires rejecting many standard principles of propositional modal logic involving iterated modal operators.

I explore some ways in which one might base an account of the fundamental metaphysics of geometry on the mathematical theory of Linear Structures recently developed by Tim Maudlin (2010). Having considered some of the challenges facing this approach, Idevelop an alternative approach, according to which the fundamental ontology includes concrete entities structurally isomorphic to functions from space-time points to real numbers.

Region R Question: How many objects — entities, things — are contained in R? Ignore the empty space. Our question might better be put, 'How many material objects does R contain?' Let's stipulate that A, B and C are metaphysical atoms: absolutely simple entities with no parts whatsoever besides themselves. So you don't have to worry about counting a particle's top half and bottom half as different objects. Perhaps they are 'point-particles', with no length, width or breadth. Perhaps they are (...) extended in space without possessing spatial parts (if that is possible). Never mind. We stipulate that A, B and C are perfectly simple. We also stipulate that they are connected as follows. A and B are stuck together in such a way that when a force is applied to one of them, they move together 'as a unit'. Moreover, the two of them together exhibit behavior that neither would exhibit on its own — Perhaps they emit a certain sound, or glow in the dark — whereas C is.. (shrink)

The conclusion of this chapter is that higher-order vagueness is universal: no sentence whatsoever is definitely true, definitely definitely true, definitely definitely definitely true, and so on ad infinitum. The argument, of which there are several versions, turns on the existence of Sorites sequences of possible worlds connecting the actual world to possible worlds where a given sentence is used in such a way that its meaning is very different. The chapter attempts to be neutral between competing accounts of the (...) nature of vagueness and definiteness. (shrink)

We develop a Bayesian framework for thinking about the way evidence about the here and now can bear on hypotheses about the qualitative character of the world as a whole, including hypotheses according to which the total population of the world is infinite. We show how this framework makes sense of the practice cosmologists have recently adopted in their reasoning about such hypotheses.

Under what conditions is a belief inferentially justified? A partial answer is found in Justification from Justification : a belief is inferentially justified only if all of the beliefs from which it is essentially inferred are justified. After reviewing some important features of JFJ, I offer a counterexample to it. Then I outline a positive suggestion for how to think about inferentially justified beliefs while still retaining a basing condition. I end by concluding that epistemologists need a model of inferentially (...) justified belief that is more permissive and more complex than JFJ. (shrink)

Ernest Sosa and others have proposed a safety condition on knowledge: If S knows p, then in the nearest (non-actual) worlds in which S believes p, p is true.1 Colloquially, this is the idea that knowing requires not being easily mistaken. Here, I will argue that like another condition requiring a counterfactual relation between a subject’s belief and the world, viz. Robert Nozick’s sensitivity condition, safety leads, in certain cases, to the unacceptable result that knowledge is not closed under known (...) implication. (shrink)

What epistemic defect needs to show up in a skeptical scenario if it is to effectively target some belief? According to the false belief account, the targeted belief must be false in the skeptical scenario. According to the competing ignorance account, the targeted belief must fall short of being knowledge in the skeptical scenario. This paper argues for two claims. The first is that, contrary to what is often assumed, the ignorance account is superior to the false belief account. The (...) second is that the ignorance account ultimately hobbles the skeptic. It does so for two reasons. First, when this account is joined with either a closure-based skeptical argument or a skeptical underdetermination argument, the best the skeptic can do is show that we don’t know that we know. And second, the ignorance account directly implies the maligned KK principle. (shrink)

This paper looks at an argument strategy for assessing the epistemic closure principle. This is the principle that says knowledge is closed under known entailment; or (roughly) if S knows p and S knows that p entails q, then S knows that q. The strategy in question looks to the individual conditions on knowledge to see if they are closed. According to one conjecture, if all the individual conditions are closed, then so too is knowledge. I give a deductive argument (...) for this conjecture. According to a second conjecture, if one (or more) condition is not closed, then neither is knowledge. I give an inductive argument for this conjecture. In sum, I defend the strategy by defending the claim that knowledge is closed if, and only if, all the conditions on knowledge are closed. After making my case, I look at what this means for the debate over whether knowledge is closed. (shrink)

Conceivability is an important source of our beliefs about what is possible; inconceivability is an important source of our beliefs about what is impossible. What are the connections between the reliability of these sources? If one is reliable, does it follow that the other is also reliable? The central contention of this paper is that suitably qualified the reliability of inconceivability implies the reliability of conceivability, but the reliability of conceivability fails to imply the reliability of inconceivability.

Is there a role for aesthetic judgements in science? One aspect of scientific practice, the use of thought experiments, has a clear aesthetic dimension. Thought experiments are creatively produced artefacts that are designed to engage the imagination. Comparisons have been made between scientific (and philosophical) thought experiments and other aesthetically appreciated objects. In particular, thought experiments are said to share qualities with literary fiction as they invite us to imagine a fictional scenario and often have a narrative form (Elgin 2014). (...) But philosophical discussions of aesthetics in science have focused mainly on the epistemic role of beauty and elegance when it comes to theories and mathematical proofs, and thought experiments have been widely overlooked. My aim in this chapter is to address how the aesthetic choices scientists make in the design of a thought experiment contribute to its function: to communicate, convince, or explain a theory or phenomenon. A key issue is whether any aesthetic features in science provide anything beyond catching our attention, or are at best, a mere heuristic aid. I respond to accounts that argue this way and show how formulation is important in scientific thought experiments and, similarly to literary fictions, there is more than one way of interpreting a thought experiment scenario. I end by considering which literary examples are most appropriate when making comparisons with thought experiments. As a result, the difference between representations in art and science raised in current discussions is not as stark as it has been made out to be, and science is a more heterogeneous practice than has been allowed. Part of the value of thought experiments in scientific practice includes the qualities they share with literary works. (shrink)

Some parents have taken steps to ensure that they have deaf children, a choice that contrasts with the interest that other parents have in enhancing the traits of their children. Julian Savulescu has argued that, morally speaking, parents have a duty to use assisted reproductive technologies to give their children the best opportunity of the best life. This view extends beyond that which is actually required of parents, which is only that they give children reasonable opportunities to form and act (...) on a conception of a life that is good for them. Does the selection of deaf children violate that responsibility? Morally speaking, parents should refrain from using assisted reproductive treatments or prenatal interventions in order to have a child with a disability. Deafness and other disabilities represent intrinsic disadvantages that cannot be offset by other advantages that families and society can offer to people. By the same token, neither should parents seek enhancements of intelligence or physical traits that would undercut intrinsic goods of human life in similar ways. These moral arguments do not, however, sustain the judgment that the law should necessarily interfere with parents' decisions in these matters, even if those choices are morally unwise. (shrink)

Bioconservative commentators argue that parents should not take steps to modify the genetics of their children even in the name of enhancement because of the damage they predict for values, identities and relationships. Some commentators have even said that adults should not modify themselves through genetic interventions. One commentator worries that genetic modifications chosen by adults for themselves will undermine moral agency, lead to less valuable experiences and fracture people's sense of self. These worries are not justified, however, since the (...) effects of modification will not undo moral agency as such. Adults can still have valuable experiences, even if some prior choices no longer seem meaningful. Changes at the genetic level will not always, either, alienate people from their own sense of self. On the contrary, genetic modifications can help amplify choice, enrich lives and consolidate identities. Ultimately, there is no moral requirement that people value their contingent genetic endowment to the exclusion of changes important to them in their future genetic identities. Through weighing risks and benefits, adults also have the power to consent to—and assume the risks of—genetic modifications for themselves in a way not possible in prenatal genetic interventions.

This paper discusses the representation and explanation of relationships between phenomena that are important in psychiatric contexts. After a general discussion of complexity in the philosophy of science, I distinguish zooming-out approaches from zooming-in approaches. Zooming-out has to do with seeing complex mental illnesses as abstract models for the purposes of both explanation and reduction. Zooming-in involves breaking complex mental illnesses into simple components and trying to explain those components independently in terms of specific causes. Connections between existing practice and (...) zooming-out are drawn, and zooming-in is criticised. (shrink)

ABSTRACTThis article offers a novel sceptical argument that the sensitivity-contextualist must say is sound; moreover, she must say that the conclusion of this argument is true at ordinary standards. The view under scrutiny has it that in different contexts knowledge-attributing sentences express different propositions, propositions which differ in the stretch of worlds across which the subject is required to track the truth. I identify the underlying reason for the sceptical result and argue that it makes sensitivity-contextualism irremediably flawed. Contextualists, I (...) conclude, should abandon sensitivity for some other piece of epistemic machinery. (shrink)

This paper is about the nature of God’s pre-creation knowledge of possible creatures. I distinguish three theories: non-qualitative singularism, qualitative singularism, and qualitative generalism, which differ in terms of whether the relevant knowledge is qualitative or non-qualitative, and whether God has singular or merely general knowledge of creatures. My main aim is to argue that qualitative singularism does not depend on a version of the Principle of Identity of Indiscernibles to the effect that, necessarily, qualitatively indiscernible individuals are identical. It (...) follows that qualitative singularism does not depend on the view that possible creatures categorically have qualitative individual essences. (shrink)

This chapter begins by sketching an account of morally responsible agency and the general conditions under which it may fail. We discuss how far individuals with psychiatric diagnoses may be exempt from morally responsible agency in the way that infants are, with examples drawn from a sample of diagnoses intended to make dierent issues salient. We further discuss a recent proposal that clinicians may hold patients responsible without blaming them for their acts. We also consider cognitively impaired subjects in the (...) light of related issues in moral and political theory, asking whether they have been unjustly excluded from liberal conceptions of political community due to their presumed lack of agency.

Anja Karnein has suggested that because of the importance of respect for persons, law and policy should require some human embryos created in vitro to be available for adoption for a period of time. If no one comes forward to adopt the embryos during that time, they may be destroyed (in the case of embryos left over from fertility medicine) or used in research (in the case of embryos created for that purpose or left over from fertility medicine). This adoption (...) option would increase the number of embryos available for couples looking for help in having children, but that effect is less important—Karnein argues—than the observance of respect for human persons. As possible persons, she holds that embryos ought to be treated, as if they will become children, if only for a while. If enacted as a matter of law and policy, an ‘adoption option’ would wrongly interfere with the dispositional rights women and men ought to have over embryos they create in the course of trying to have children. Karnein's proposal would also deprive researchers of certainty that the embryos they create for research would actually be available that way, leading to increased burdens of time and money and maybe even to more embryos than would otherwise be produced. Karnein's analysis does not show, moreover, that any duty of rescue applies to embryos. No woman is required to adopt any embryo, which significantly undercuts the justification for an obligatory adoption period. (shrink)

There are no technologies at the present time that would allow parents to select the sexual orientation of their children. But what if there were? Some commentators believe that parents should be able to use those techniques so long as they are effective and safe. Others believe that these techniques are unethical because of the dangers they pose to homosexual men and women in general. Both sides point to motives and consequences when trying to analyse the ethics of this question. (...) These arguments are reviewed, and it is concluded that opponents of these technologies have not shown good reason why the law or policy should override parental choice in this matter. In general, therefore, if technologies become available to choose the sexual orientation of children, parents should be allowed to use them, provided they are safe and disrupt no interest of the child. This use will, at the very least, protect homosexual children from parents who do not want them, but it will also allow parents who want homosexual children to make that choice as well. (shrink)

Some commentators argue that conception constitutes the onset of human personhood in a metaphysical sense. This threshold is usually invoked as the basis both for protecting zygotes and embryos from exposure to risks of death in clinical research and fertility medicine and for objecting to abortion, but it also has consequences for certain religious perspectives, including Catholicism whose doctrines directly engage questions of personhood and its meanings. Since more human zygotes and embryos are lost than survive to birth, conferral of (...) personhood on them would mean – for those believing in personal immortality – that these persons constitute the majority of people living immortally despite having had only the shortest of earthly lives. For those believing in resurrection, zygotes and embryos would also be restored to physical lives. These outcomes do not mean that conception cannot function as a metaphysical threshold of personhood, but this interpretation carries costs that others do not. For example, treating conception as a moral threshold of respect for human life in general, rather than as a metaphysical threshold of personhood, would obviate the prospect of the afterlife being populated in the main by persons who have never lived more than a few hours or days.

In an earlier paper, I presented a novel objection to closure-based skeptical arguments. There I argued that the best account of what makes skeptical scenarios effective cripples the closure-based skeptical arguments that use those scenarios. On behalf of the skeptic, Christopher Buford and Anthony Brueckner have replied to my objection. Here I review my original argument, criticize their replies, and highlight two important issues for further investigation.

Historically left to the margins, the topics of imagination and creativity have gained prominence in philosophy of science, challenging the once dominant distinction between ‘context of discovery’ and ‘context of justification’. The aim of this chapter is to explore imagination and creativity starting from issues within contemporary philosophy of science, making connections to these topics in other domains along the way. It discusses the recent literature on the role of imagination in models and thought experiments, and their comparison with fictions. (...) It then turns to the importance of constraints on imaginings in the scientific domain, as well as whether constraints can hinder creativity. The second part of the paper focuses on the social dimensions of science. It considers imagination and creativity of scientific communities, asks whether the institution of science promotes creativity (and whether we want it to) or if it encourages conservativeness, and ends with a reflection on the politics of imagination and creativity in science.

As effective altruists often point out affluent people can do great good for others without having to make significant self-sacrifices. What is the correct moral assessment of patterns of giving that bring about great good and yet carry little in the way of self-sacrifice? Here I will clarify this question, state why it is important, and argue for an answer to it. After sketching the intuitive category of the morally best acts, I argue that self-sacrifice is not a condition that (...) an act must meet to be among the morally best acts. I argue that self-sacrifice is instead a condition that agents must meet to be deserving of the highest praise. (shrink)

Letheby’s book is an engaging and crystal-clear exploration of the philosophical issues raised by the use of psychedelic drugs. In this paper, we focus on the epistemological issues Letheby examines in chapter 8 and argue that his analysis requires an agency-first approach to epistemic evaluation. On an agency-first approach, epistemic evaluation is about identifying the skills agents needs to acquire in order to pursue and fulfil their epistemic goals.

The traditional way of drawing the a priori/a posteriori distinction, bequeathed to us by Kant, leads to overestimating the role that experience plays in justifying ourbeliefs. There is an irony in this: though Kant was in the rationalist camp, his way of drawing the distinction gives an unfair advantage to radical empiricism. I offer an alternative way of drawing the distinction, one that does not bias the rationalist/empiricist debate.

In the heyday of linguistic philosophy an experimental philosophy movement was born, and this chapter tells its story, both in its historical and philosophical context and as it is connected to controversies about experimental philosophy today. From its humble beginnings at the Vienna Circle, the movement matured into a vibrant research program at Oslo, and sought adventure at Berkeley thereafter. The harsh and uncharitable reaction it met is surprising but understandable in light of disciplinary tensions and the legacy of antipsychologism—sentiments (...) and arguments which have reemerged today, albeit in modified form. Yet the research at Oslo remained unperturbed and it flourished in both its theory and its applications, which spanned the philosophical domain. The Berkeley years were short but intense, as exemplified by their engagement with ordinary-language philosophy, J.L. Austin, and the theory of communicative significance. (shrink)

A capability approach has been proposed to risk analysis, where risk is conceptualized as the probability that capabilities are reduced. Capabilities refer to the genuine opportunities of individuals to achieve valuable doings and beings, such as being adequately nourished. Such doings and beings are called functionings. A current debate in risk analysis and other fields where a capability approach has been developed concerns whether capabilities or actual achieved functionings should be used. This paper argues that in risk analysis the consequences (...) of hazardous scenarios should be conceptualized in terms of capabilities, not achieved functionings. Furthermore, the paper proposes a method for assessing capabilities, which considers the levels of achieved functionings of other individuals with similar boundary conditions. The capability of an individual can then be captured statistically based on the variability of the achieved functionings over the considered population. (shrink)

Joseph Newhard (2017) argues that a libertarian anarchist society would be at a serious military disadvantage if it extended the nonaggression principle to include potential foreign invaders. He goes so far as to recommend cultivating the ability to launch a nuclear attack on foreign cities. In contrast, I argue that the free society would derive its strength from a total commitment to property rights and the protection of innocent life. Both theory and history suggest that a free society would be (...) capable of defending itself, and indeed that it would probably use other means to avoid military conflict altogether. (shrink)

This paper argues that the disagreement between positivists and nonpositivists about law is substantive rather than merely verbal, but that the depth and persistence of the disagreement about law, unlike for the case of morality, threatens skepticism about law. The range of considerations that can be brought to bear to help resolve moral disagreements is broader than is the case for law, thus improving the prospects of reconciliation in morality. But the central argument of the paper is that law, unlike (...) morality, is a concept-dependent social kind, in the sense that law cannot exist in a society without someone in that society having the concept of law. Since the existence of the social kind law is largely dependent on the existence of the corresponding concept, when different actors have different concepts, they can end up creating different kinds. Hence, the difference between positivists and nonpositivists is not just a conceptual one but is capable of giving rise to different legal norms. (shrink)

The pandemic significantly raised the stakes for the translation of bioethics insights into policy. The novelty, range and sheer quantity of the ethical problems that needed to be addressed urgently within public policy were unprecedented and required high‐bandwidth two‐way transfer of insights between academic bioethics and policy. Countries such as the United Kingdom, which do not have a National Ethics Committee, faced particular challenges in how to facilitate this. This paper takes as a case study the brief career of the (...) Ethics Advisory Board (EAB) for the NHS Covid‐19 App, which shows both the difficulty and the political complexity of policy‐relevant bioethics in a pandemic and how this was exacerbated by the transience and informality of the structures through which ethics advice was delivered. It analyses how and why, after EAB's demise, the Westminster government increasingly sought to either take its ethics advice in private or to evade ethical scrutiny of its policies altogether. In reflecting on EAB, and these later ethics advice contexts, the article provides a novel framework for analysing ethics advice within democracies, defining four idealised stances: the pure ethicist, the advocate, the ethics arbiter and the critical friend.
