By the 1880s it had become clear that the intellectual tide in Britain was turning against the idea of a minimal state. Under the influence of the New Idealists, the Liberal Party, once the champion of individual liberty, had changed into an organ for interventionist legislation. Challenging this movement was an assortment of anti-collectivists including Old Liberals, Tories, and radical individualists. Spearheading the defence of individualism was the 10th Earl of Wemyss, Francis Wemyss-Charteris-Douglas. Most famous for his role in the (...) formation of the Liberty and Property Defence League, Wemyss worked tirelessly in parliament to obstruct legislation deemed inimical to liberty, as well as to organise a mass educational effort to instruct the public about the errors of collectivist philosophy and policy. This paper examines the role Wemyss played within late Victorian individualism and considers how the melding of traditionalism and individualism provided an intellectual home for libertarianism on the Right.

The burden of COVID-19 has been widely unequal across the provinces and territories of Canada. At last count, infection rates vary from 4,003 per 100,000 people in Nunavut to 12,253 per 100,000 people in the North West Territories. The death rate from COVID-19 varies from 0 per 100,000 in PEI to 158 per 100,000 in Quebec. Each province and territory established different public health measures at different times, sometimes lifting them briefly only to have to reestablish them quickly. Each province (...) and territory has also managed the question of who will be required to be vaccinated, and how that requirement will be monitored, very differently. The gendered... (shrink)

One of the currently popular dogmata of anti-consequentialism is that consequentialism doesn't respect, recognize, or in some important way account for what is referred to as the The charge is often made, but rarely explained in any detail, much less argued for. In this paper I explain what I take to be the most plausible interpretation of the separateness of persons charge. I argue that the charge itself can be deconstructed into at least two further objections to consequentialist theories. These (...) objections amount to (i) the rejection of axiological aggregation, and (ii) the rejection of deontic aggregation. Of these two objections, I argue that the first one, though often made, is untenable. I also argue that the second objection, in its various forms, relies on distinctions whose moral significance is vigorously denied by almost all consequentialist theorists. I thus argue that the separateness of persons objection poses no special threat to consequentialism. (shrink)

Healthcare Ethics, Law and Professionalism: Essays on the Works of Alastair V Campbell features 15 original essays on bioethics, and healthcare ethics specifically. The volume is in honour of Professor Alastair V Campbell, who was the founding editor of the internationally-renowned Journal of Medical Ethics, and the founding director of three internationally leading centres in bioethics, in Otago, New Zealand, Bristol, UK, and Singapore. Campbell was trained in theology and philosophy and throughout his career worked with colleagues from (...) various disciplines, including law and various branches of healthcare. The diversity of topics and depth of contributors' insights reflect the breadth and impact of Campbell's philosophical work and policy contributions to healthcare ethics. Throughout his long academic career, Campbell's emphasis on healthcare ethics being practice-oriented, yet driven by critical reflection, has shaped the field in vital ways. The chapters are authored by leading scholars in healthcare ethics and law. Directly engaging with Campbell's work and influence, the essays discuss essential questions in healthcare ethics relating to its methodology and teaching, its intersection with law and policy, medical professionalism, religion, and its translation in different cultural settings. Chapters also grapple with specific enduring topics, such as the doctor-patient relationship, justice in health and biomedical research, and treatment of the human body and the dead. (shrink)

There is a systematic and suggestive analogy between grounding and causation. In my view, this analogy is no coincidence. Grounding and causation are alike because grounding is a type of causation: metaphysical causation. In this paper I defend the identification of grounding with metaphysical causation, drawing on the causation literature to explore systematic connections between grounding and metaphysical dependence counterfactuals, and I outline a non-reductive counterfactual theory of grounding along interventionist lines.

This book defends a radical new theory of contingency as a physical phenomenon. Drawing on the many-worlds approach to quantum theory and cutting-edge metaphysics and philosophy of science, it argues that quantum theories are best understood as telling us about the space of genuine possibilities, rather than as telling us solely about actuality. When quantum physics is taken seriously in the way first proposed by Hugh Everett III, it provides the resources for a new systematic metaphysical framework encompassing possibility, necessity, (...) actuality, chance, counterfactuals, and a host of related modal notions. -/- Rationalist metaphysicians argue that the metaphysics of modality is strictly prior to any scientific investigation; metaphysics establishes which worlds are possible, and physics merely checks which of these worlds is actual. Naturalistic metaphysicians respond that science may discover new possibilities and new impossibilities. This book's quantum theory of contingency takes naturalistic metaphysics one step further, allowing that science may discover what it is to be possible. As electromagnetism revealed the nature of light, as acoustics revealed the nature of sound, as statistical mechanics revealed the nature of heat, so quantum physics reveals the nature of contingency.

Alastair Norcross argues that the basic judgments of morality are essentially comparative: alternatives are judged to be better or worse than each other. Notions such as right and wrong are not part of the fundamental subject matter of moral theory, but are constructed in a context-relative fashion out of the basic comparative judgments.

This paper outlines a non-reductive counterfactual account of grounding along interventionist lines, and uses the account to argue that taking grounding seriously requires ascribing non-trivial truth-conditions to a range of counterpossible counterfactuals. This result allows for a diagnosis of a route to scepticism about grounding, as deriving at least in part from scepticism about non-trivial counterpossible truth and falsity.

This article explores three ways in which physics may involve counterpossible reasoning. The first way arises when evaluating false theories: to say what the world would be like if the theory were true, we need to evaluate counterfactuals with physically impossible antecedents. The second way relates to the role of counterfactuals in characterizing causal structure: to say what causes what in physics, we need to make reference to physically impossible scenarios. The third way is novel: to model metaphysical dependence in (...) physics, we need to consider counterfactual consequences of metaphysical impossibilities. Physics accordingly bears substantial and surprising counterpossible commitments. (shrink)

Background: Expanded newborn screening generates incidental results, notably carrier results. Yet newborn screening programmes typically restrict parental choice regarding receipt of this non-health serving genetic information. Healthcare providers play a key role in educating families or caring for screened infants and have strong beliefs about the management of incidental results. Methods: To inform policy on disclosure of infant sickle cell disorder (SCD) carrier results, a mixed-methods study of healthcare providers was conducted in Ontario, Canada, to understand attitudes regarding result management (...) using a cross-sectional survey (N = 1615) and semistructured interviews (N = 42). Results: Agreement to reasons favouring disclosure of SCD carrier results was high (65.1%–92.7%) and to reasons opposing disclosure was low (4.1%–18.1%). Genetics professionals expressed less support for arguments favouring disclosure (35.3%–78.8%), and more agreement with arguments opposing disclosure (15.7%–51.9%). A slim majority of genetics professionals (51.9%) agreed that a reason to avoid disclosure was the importance of allowing the child to decide to receive results. Qualitatively, there was a perceived “duty” to disclose, that if the clinician possessed the information, the clinician could not withhold it. Discussion: While a majority of respondents perceived a duty to disclose the incidental results of newborn screening, the policy implications of these attitudes are not obvious. In particular, policy must balance descriptive ethics (ie, what providers believe) and normative ethics (ie, what duty-based principles oblige), address dissenting opinion and consider the relevance of moral principles grounded in clinical obligations for public health initiatives.

In ‘Quiddistic Knowledge’ (Schaffer in Philos Stud 123:1–32, 2005), Jonathan Schaffer argued influentially against the view that the laws of nature are metaphysically necessary. In this reply I aim to show how a coherent and well-motivated form of necessitarianism can withstand his critique. Modal necessitarianism—the view that the actual laws are the laws of all possible worlds—can do justice to some intuitive motivations for necessitarianism, and it has the resources to respond to all of Schaffer’s objections. It also has certain (...) advantages over contingentism in the domain of modal epistemology. I conclude that necessitarianism about laws remains a live option. (shrink)

Distinctions in fundamentality between different levels of description are central to the viability of contemporary decoherence-based Everettian quantum mechanics (EQM). This approach to quantum theory characteristically combines a determinate fundamental reality (one universal wave function) with an indeterminate emergent reality (multiple decoherent worlds). In this chapter I explore how the Everettian appeal to fundamentality and emergence can be understood within existing metaphysical frameworks, identify grounding and concept fundamentality as promising theoretical tools, and use them to characterize a system of explanatory (...) levels (with associated laws of nature) for EQM. This Everettian level structure encompasses and extends the ‘classical’ levels structure. The ‘classical’ levels of physics, chemistry, biology, etc. are recovered, but they are emergent in character and potentially variable across Everett worlds. EQM invokes an additional fundamental level, not present in the classical levels picture, and a novel potential role for self-location in interlevel metaphysics. When given a modal realist interpretation, EQM also makes trouble for supervenience-based approaches to levels. (shrink)

This chapter contains section titled: Introduction The Demandingness Objection Scalar Utilitarianism Wrongness as Blameworthiness Rightness and Goodness as Guides to Action.

David Wallace has given a decision-theoretic argument for the Born Rule in the context of Everettian quantum mechanics. This approach promises to resolve some long-standing problems with probability in EQM, but it has faced plenty of resistance. One kind of objection charges that the requisite notion of decision-theoretic uncertainty is unavailable in the Everettian picture, so that the argument cannot gain any traction; another kind of objection grants the proof’s applicability and targets the premises. In this article I propose some (...) novel principles connecting the physics of EQM with the metaphysics of modality, and argue that in the resulting framework the incoherence problem does not arise. These principles also help to justify one of the most controversial premises of Wallace’s argument, ‘branching indifference’. Absent any a priori reason to align the metaphysics with the physics in some other way, the proposed principles can be adopted on grounds of theoretical utility. The upshot is that Everettians can, after all, make clear sense of objective probability. 1 Introduction2 Setup3 Individualism versus Collectivism4 The Ingredients of Indexicalism5 Indexicalism and Incoherence5.1 The trivialization problem5.2 The uncertainty problem6 Indexicalism and Branching Indifference6.1 Introducing branching indifference6.2 The pragmatic defence of branching indifference6.3 The non-existence defence of branching indifference6.4 The indexicalist defence of branching indifference7 Conclusion.

Many significant harms, such as the mass suffering of animals on factory farms, can only be prevented, or at least lessened, by the collective action of thousands, or in some cases millions, of individual agents. In the face of this, it can seem as if individuals are powerless to make a difference, and thus that they lack reasons, at least from the consequentialist perspective, to refrain from eating meat. This has become known as the “causal impotence” problem. The standard response (...) is to appeal to expected utility calculations. Recently, this response has been attacked, mostly on the grounds that the relevant causal mechanisms are more complex than its proponents are said to assume. In this paper, I argue that the attacks are unsuccessful, both at undermining specific expected utility calculations urged by me and Kagan, or even at showing that significantly different expected utility calculations wouldn’t justify the relevant behavior.

In On the Plurality of Worlds (Lewis 1986), David Lewis imposes a condition on realist theories of modality which he calls ‘plenitude’. Lewis apparently assigns this condition considerable importance, and uses it to motivate his Humean principle of recombination, but he never says exactly what plenitude amounts to. This chapter first sets aside some obvious ways of reconstructing the plenitude criterion which do not fit with the textual evidence. An objection to modal realism due to John Divers and Joseph Melia (...) (Divers and Melia 2002) is diagnosed as equivocating between an overly-demanding plenitude constraint and a weaker constraint which fails to establish their conclusion. An alternative deflationary interpretation of the plenitude condition has it following from an application of standard theoretical virtues to a modal realist’s total theory; Lewis’ correspondence provides new evidence in support of this interpretation. The deflationary plenitude criterion also has broader application, beyond Lewisian modal realism. (shrink)

Simon Saunders and David Wallace have proposed an attractive semantics for interpreting linguistic communities embedded in an Everettian multiverse. It provides a charitable interpretation of our ordinary talk about the future, and allows us to retain a principle of bivalence for propositions and to retain the law of excluded middle in the logic of propositions about the future. But difficulties arise when it comes to providing an appropriate account of the metaphysics of macroscopic objects and events. I evaluate various metaphysical (...) frameworks which might be combined with the Saunders–Wallace semantics. I conclude that the most appropriate metaphysics to underwrite the semantics renders Everettian quantum mechanics a theory of non-overlapping worlds. (shrink)

Kierkegaard and Philosophy makes many of the most important papers on Kierkegaard available in one place for the first time. These seventeen essays, written over a period of over twenty years, have all been substantially revised or specially prepared for this collection, with a new introduction by the author. In the first part, Alastair Hannay concentrates on Kierkegaard's central philosophical writings, offering closely text-based accounts of the slient concepts Kierkegaard uses. The second part shows the relevance of other thinkers' (...) treatments of shared themes, pointing our where they differ from Kierkegaard. The concluding chapter provides a reason Kierkegaard himself would give for disagreeing with those who claim his texts are infinitely interpretable. Written by the world's foremost Kierkegaard scholar and translator, Kierkegaard and Philosophy is an indispensible resource for all students of Kierkegaard's work. (shrink)

Frances Kamm's aptly titled Intricate Ethics is a tour de force of what Peter Unger calls the ‘preservationist’ approach to ethical theory. Here is some of what she says about her methodology: Consider as many case-based judgments of yours as prove necessary. Do not ignore some case-based judgments, assuming they are errors, just because they conflict with simple or intuitively plausible principles that account for some subset of your case-based judgments. Work on the assumption that a different principle can account (...) for all of the judgments. Be prepared to be surprised at what this principle is . . . . I say, consider your case-based judgments, rather than a survey of everyone's judgments. This is because I believe that much more is accomplished when one person considers her judgments and then tries to analyze and justify their grounds than if we do mere surveys. (shrink)

In this paper I assess the prospects for combining contemporary Everettian quantum mechanics (EQM) with branching-time semantics in the tradition of Kripke, Prior, Thomason and Belnap. I begin by outlining the salient features of ‘decoherence-based’ EQM, and of the ‘consistent histories’ formalism that is particularly apt for conceptual discussions in EQM. This formalism permits of both ‘branching worlds’ and ‘parallel worlds’ interpretations; the metaphysics of EQM is in this sense underdetermined by the physics. A prominent argument due to Lewis (On (...) the Plurality of Worlds, 1986 ) supports the non-branching interpretation. Belnap et al. (Facing the Future: Agents and Choices in Our Indeterministic World, 2001 ) refer to Lewis’ argument as the ‘Assertion problem’, and propose a pragmatic response to it. I argue that their response is unattractively ad hoc and complex, and that it prevents an Everettian who adopts branching-time semantics from making clear sense of objective probability. The upshot is that Everettians are better off without branching-time semantics. I conclude by discussing and rejecting an alternative possible motivation for branching time. (shrink)

Suppose that a very large number of people, say one billion, will suffer a moderately severe headache for the next twenty-four hours. For these billion people, the next twenty-four hours will be fairly unpleasant, though by no means unbearable. However, there will be no side-effects from these headaches; no drop in productivity in the work-place, no lapses in concentration leading to accidents, no unkind words spoken to loved ones that will later fester. Nonetheless, it is clearly desirable that these billion (...) people avoid the headaches. Even though the headaches are moderate, they are impervious to pain-killing drugs, acupuncture, transcendental meditation, and just about any other remedy. In fact, there is only one way in which the headaches can be avoided. In a remote South American village, a young woman, Agnes, is suffering from a fever. A simple dose of antibiotics will save her life, otherwise she will die. If, and only if, she dies, the billion headaches will be prevented. You just happen to be passing through the village, in full knowledge of the circumstances. Although not a doctor (and therefore not bound by codes of professional ethics, Hippocratic oaths, etc.), you possess the requisite dose of antibiotics, for which you have no other use, and which will become useless, if not used in the next two hours.

It is usually assumed to be possible, and sometimes even desirable, for consequentialists to make judgments about both the rightness and the goodness of actions. Whether a particular action is right or wrong is one question addressed by a consequentialist theory such as utilitarianism. Whether the action is good or bad, and how good or bad it is, are two others. I will argue in this paper that consequentialism cannot provide a satisfactory account of the goodness of actions, on the (...) most natural approach to the question. I will also argue that, strictly speaking, a consequentialist cannot judge one action to be better or worse than another action performed at a different time or by a different person. Even if such theories are thought to be primarily concerned with rightness, this would be surprising, but in the light of recent work challenging the place of rightness in consequentialism1, it seems particularly disturbing. If actions are neither right (or wrong) nor good (or bad), what moral judgments do apply to them? Doesn't the rejection of both rightness and goodness, as applied to actions, leave consequentialism unacceptably impoverished? On the contrary, I will argue that consequentialism is actually strengthened by the realization that actions can only be judged as better or worse than possible alternatives. (shrink)

The author explores different views of the significance of the human body and contrasts those which regard it as a commodity or personal possession with those which stress its moral value as integral to the personal identity of individuals.

Quantum physics is believed to be the fundamental theory underlying our understanding of the physical universe. However, it is based on concepts and principles that have always been difficult to understand and controversial in their interpretation. This book aims to explain these issues using a minimum of technical language and mathematics. After a brief introduction to the ideas of quantum physics, the problems of interpretation are identified and explained. The rest of the book surveys, describes and criticises a range of (...) suggestions that have been made with the aim of resolving these problems; these include the traditional, or 'Copenhagen' interpretation, the possible role of the conscious mind in measurement, and the postulate of parallel universes. This new edition has been revised throughout to take into account developments in this field over the past fifteen years, including the idea of 'consistent histories' to which a completely new chapter is devoted.

There is much to admire in this book. As a rigorous and systematic physics-oriented presentation of an austere empiricist fundamental metaphysics, it has no real rivals. The clarity with which the overall vision is presented will provide a valuable stalking-horse for those who would defend less austere approaches in the future. Esfeld and Deckert never shy away from the radical consequences of their approach, or try to disguise its revisionary nature. I also found several points of agreement with Esfeld and (...) Deckert’s metaphysical outlook. In particular, I thought their form of structural realism sophisticated and plausible and their application of it to contemporary physics salutary. Fundamental metaphysics would be a more respectable discipline if all of its exponents felt the need to show how their preferred ontology plays out in the context of real physics. These points of agreement noted, I will concentrate in these comments on points where I disagree with Esfeld and Deckert. From my perspective, the metaphysical project of the book is subject to two serious objections: firstly, it remains insufficiently naturalistic and overly a prioristic, and secondly, it drains much of the explanatory power out of fundamental physics.

How should we respond to cases of disagreement where two epistemic agents have the same evidence but come to different conclusions? Adam Elga has provided a Bayesian framework for addressing this question. In this paper, I shall highlight two unfortunate consequences of this framework, which Elga does not anticipate. Both problems derive from a failure of commutativity between application of the equal weight view and updating in the light of other evidence.

My aims in this article are threefold. First, I evaluate attempts to drive a wedge between the human and the natural in order to show that destroyed natural environments and extinct species cannot be restored; next, I examine the analogy between aesthetic value and the value of natural environments; and finally, I suggest briefly a different set of analogies with such human associations as families and cultures. My tentative conclusion is that while the recreation of extinct species may be logically (...) impossible, the restoration of natural environments raises only (formidable, no doubt) technical difficulties. Opponents of destructive developments which do not exterminate species, therefore, had better look elsewhere, rather than relying on the claim that restoration is logically impossible. (shrink)

If consequentialism is understood as claiming, at least, that the moral character of an action depends only on the consequences of the action, it might be thought that the difficulty of knowing what all the consequences of any action will be poses a problem for consequentialism.

Medical (...) Ethics also covers issues having to do with the beginning and end of life, as well as ethical questions surrounding the human body and the use of human tissue, confidentiality and AIDS, care of the mentally ill, and the implications of genetic technology. Each chapter presents a range of ethical views, drawing both from traditional philosophy and the most recent contemporary trends. The theoretical discussion is extended and illustrated by case studies and examples. This book is a non-technical guide to ethics written with the needs of medical students and medical practitioners in mind. It will also appeal to students and practitioners of allied health professions, and for all users of health care services. (shrink)

Sensory substitution devices (SSDs) aim to compensate for the loss of a sensory modality, typically vision, by converting information from the lost modality into stimuli in a remaining modality. “The vOICe” is a visual-to-auditory SSD which encodes images taken by a camera worn by the user into “soundscapes” such that experienced users can extract information about their surroundings. Here we investigated how much detail was resolvable during the early induction stages by testing the acuity of blindfolded sighted, naïve vOICe users. (...) Initial performance was well above chance. Participants who took the test twice as a form of minimal training showed a marked improvement on the second test. Acuity was slightly but not significantly impaired when participants wore a camera and judged letter orientations “live”. A positive correlation was found between participants' musical training and their acuity. The relationship between auditory expertise via musical training and the lack of a relationship with visual imagery, suggests that early use of a SSD draws primarily on the mechanisms of the sensory modality being used rather than the one being substituted. If vision is lost, audition represents the sensory channel of highest bandwidth of those remaining. The level of acuity found here, and the fact it was achieved with very little experience in sensory substitution by naïve users is promising. (shrink)

If the most familiar overlapping interpretation of Everettian quantum mechanics is correct, then each of us is constantly splitting into multiple people. This consequence gives rise to the quantum doomsday argument, which threatens to draw crippling epistemic consequences from EQM. However, a diverging interpretation of EQM undermines the quantum doomsday argument completely. This appears to tell in favour of the diverging interpretation. But it is surprising that a metaphysical question that is apparently underdetermined by the physics should be settled by (...) purely epistemological considerations; and I argue that the positive case for divergence based on the quantum doomsday effect is ultimately unsuccessful. I discuss how some influential treatments of Everettian confirmation handle the quantum doomsday puzzle, and suggest that it can most satisfyingly be resolved via a naturalistic approach to the metaphysics of modality.

In the forceful final chapter of the book, Campbell articulates ethical standards for just health-care delivery in the United States--standards that, above all, take account of deep religious faith and concern for one's neighbor.

Dispositions can combine as vector sums. Recent authors on dispositions, such as George Molnar and Stephen Mumford, have responded to this feature of dispositions by introducing a distinction between effects and contributions to effects, and by identifying disposition-manifestations with the latter. But some have been sceptical of the reality or knowability of component vectors; Jennifer McKitrick (forthcoming) presses these concerns against the conception of manifestations as contributions to effects. In this paper, I aim to respond to McKitrick's arguments and to (...) defend the metaphysical and epistemological propriety of component vectors. My strategy appeals to varying kinematic frames of reference. By transforming to the appropriate non-inertial frame, component acceleration vectors can be transformed into resultant acceleration vectors, and in such frames they become directly observable. Being a component acceleration vector and being a resultant acceleration vector are both frame-dependent properties of properties; they are not to be thought of as intrinsic or fundamental properties of an acceleration vector, but as artefacts of our frame-dependent notation for representing vector quantities. To conclude the paper, I defend the view proposed against two styles of objection. The first objection resurrects scepticism about component vectors as scepticism about fundamental component vectors. The second objection questions the need for reference frames in the explanation by invoking a 'counterfactual' theory of contributions. (shrink)
