For the purposes of this monograph, "by a degree" is meant a degree of recursive unsolvability. A degree [script bold]m is said to be minimal if 0 is the unique degree less than [script bold]m. Each of the six chapters of this self-contained monograph is devoted to the proof of an existence theorem for minimal degrees.

This volume is not restricted to papers presented at the 1988 Colloquium, but instead aims to provide the reader with a (relatively) coherent reading on Algebraic Logic, with an emphasis on current research. To help the non-specialist reader, the book contains an introduction to cylindric and relation algebras by Roger D. Maddux and an introduction to Boolean Algebras by Bjarni Joacute;nsson.

'Leading economists presenting fundamentally important issues in economic theory' is the theme of the Nancy Schwartz lectures series held annually at the J. L. Kellogg Graduate School of Management of Northwestern University. Reporting on lectures delivered in the years 1983 through 1997, this collection of essays discusses economic behavior at the individual and group level and the implications to the performance of economic systems. Using non-technical language, the speakers present theoretical, experimental, and empirical analysis of decision making under uncertainty and (...) under full and bounded rationality, the influence of economic incentives and habits, and the effects of learning and evolution on dynamic choice. Perfect competition, economic development, social insurance and social mobility, and negotiation and economic survival, are major economic subjects analyzed through our understanding of economic behavior.

What is the relation between a reason and an action when the reason explains the action by giving the agent's reason for doing what he did? We may call such explanations rationalizations, and say that the reason rationalizes the action. In this paper I want to defend the ancient - and common-sense - position that rationalization is a species of ordinary causal explanation. The defense no doubt requires some redeployment, but not more or less complete abandonment of the position, as (...) urged by many recent writers. (shrink)

In the debate over clinicians’ conscience, there is a greater ethical, legal, and scholarly focus on negative, rather than positive, claims of conscience. This asymmetry produces a seemingly unjustified double standard with respect to clinicians’ conscience under the law. For example, a Roman Catholic physician working at a secular institution may refuse to provide physician-aid-in-dying on the basis of conscience, but a secular physician working at a Roman Catholic institution may not insist on providing physician-aid-in-dying on the basis of conscience. (...) This article outlines arguments against this asymmetry and critiques them for failing to distinguish between positive claims of conscience as positive or negative rights. I suggest the asymmetry debate should be focused on whether positive claims of conscience as positive rights ought to enjoy the same protections as negative claims of conscience. Clarifying the debate in this way helps elucidate some of the best reasons for the asymmetry, which these arguments have not addressed. This article does not take a definitive position on whether the asymmetry is justified, but attempts to bring some focus to the debate by directing arguments against the asymmetry to address the significant differences between positive claims of conscience as positive rights and negative claims of conscience.

What is the proper role of a clinical ethics consultant’s religious beliefs in forming recommendations for clinical ethics consultation? Where Janet Malek has argued that religious belief should have no influence on the formation of a CEC’s recommendations, Clint Parker has argued a CEC should freely appeal to all their background beliefs, including religious beliefs, in formulating their recommendations. In this paper, I critique both their views by arguing the position envisioned by Malek puts the CEC too far from religion (...) and the position envisioned by Parker puts the CEC too close. For a CEC to give recommendations about what is morally prohibited, permissible, or obligatory in the clinic, I propose a view of the CEC that is neither religious nor non-religious but quasi-religious. I argue that a quasi-religious approach avoids the problems of both religious and non-religious views while preserving their benefits. Additionally, a quasi-religious view resists the marginalization of “religious” traditions that occurs when secular ethicists come to think of their approach as somehow distinctly non-religious.

This paper provides a close reading of Erwin Straus’ “The Upright Posture” from a disability studies perspective. Straus argues that the upright posture dominates the human world. But he excludes those who dwell in it otherwise. By reviewing phenomenological disability literature, this paper asks what a disabled phenomenology would look like, one rooted in the problem of inclusion from the outset. Disabled phenomenology addresses ‘subjectivity’ critically, asking: what socio-material arrangements make subjectivity possible in the first place? This project is, I (...) argue, equal parts political economy and existential phenomenology. I conclude with some suggestions for future research. (shrink)

There is more than one way to say that composition is identity. Yi has distinguished the Weak Composition thesis from the Strong Composition thesis and attributed the former to David Lewis while noting that Lewis associates something like the latter with me. Weak Composition is the thesis that the relation between the parts collectively and their whole is closely analogous to identity. Strong Composition is the thesis that the relation between the parts collectively and their whole is identity. Yi is (...) right that Strong Composition does not fully reflect my view. We must recognize further what, borrowing Lewis's characterization, could be called the "stronger, and stranger" Composition thesis, or what I'll call the Stronger Composition thesis for short. On Strong Composition, it is only collectively that the parts are identical with the whole. On Stronger Composition, they are individually identical with it as well. I will explain and motivate this thesis. (shrink)

One of the most significant and persistent debates in secular clinical ethics is the question of ethics expertise, which asks whether ethicists can make justified moral recommendations in active patient cases. A critical point of contention in the ethics expertise debate is whether there is, in fact, a bioethical consensus upon which secular ethicists can ground their recommendations and whether there is, in principle, a way of justifying such a consensus in a morally pluralistic context. In a series of recent (...) articles in this journal, Janet Malek defends a positive view of ethics expertise, claiming that secular ethicists should comport their recommendations with bioethical consensus. In response, Nick Colgrove and Kelly Kate Evans deny the existence of a secular bioethical consensus; question why, even if it did exist, consensus should be considered a reliable way of resolving bioethical questions; and recommend a friendlier approach to clinical ethics based on the thought of H. Tristram Engelhardt Jr. In this article, I respond to Colgrove and Evans on all three points. In part one, I show there is a secular bioethical consensus but note it could be better consolidated and created through a more systematic and inclusive process. In part two, I argue that bioethical consensus is morally justified but note that this justification cannot be plausibly based upon claims that it only invokes moral principles available to or shared by all. In part three, I argue Engelhardt’s approach cannot be described as “friendlier” to clinical ethics because it is incompatible with many current healthcare laws and policies. (shrink)

How is it possible for David Hume to be both withering skeptic and constructive theorist? I recommend an answer like the Pyrrhonian answer to the question how it is possible to suspend all judgment yet engage in active daily life. Sextus Empiricus distinguishes two kinds of assent: one suspended across the board and one involved with daily living. The first is an act of will based on appreciation of reasons; the second is a causal effect of appearances. Hume makes the (...) same distinction, only he extends the sort of assent involved in daily life to theoretical matters as well. He is a skeptic both in finding no reason to grant the first sort of assent and in being subject to the second. (shrink)

Douglas Diekema has argued that it is not the best interest standard, but the harm principle that serves as the moral basis for ethicists, clinicians, and the courts to trigger state intervention to limit parental authority in the clinic. Diekema claims the harm principle is especially effective in justifying state intervention in cases of religiously motivated medical neglect in pediatrics involving Jehovah’s Witnesses and Christian Scientists. I argue that Diekema has not articulated a harm principle that is capable of justifying (...) state intervention in these cases. Where disagreements over appropriate care are tethered to metaphysical disagreements, it is moral-metaphysical standards, rather than merely moral standards, that are needed to provide substantive guidance. I provide a discussion of Diekema’s harm principle to the broader end of highlighting an inconsistency between the theory and practice of secular bioethics when overriding religiously based medical decisions. In a secular state, ethicists, clinicians, and the courts are purportedly neutral with respect to moral-metaphysical positions, especially regarding those claims considered to be religious. However, the practice of overriding religiously based parental requests requires doffing the mantle of neutrality. In the search for a meaningful standard by which to override religiously based parental requests in pediatrics, bioethicists cannot avoid some minimal metaphysical commitments. To resolve this inconsistency, bioethicists must either begin permitting religiously based requests, even at the cost of children’s lives, or admit that at least some moral-metaphysical disputes can be rationally adjudicated.

This paper is divided into three sections. The first presents some examples of the killing/letting die distinction. The second draws a further distinction between what I call negative and positive cases of acting or refraining. Here I argue that the moral significance of the acting/refraining distinction is different for positive and for negative cases. In the third section I apply the above distinction to euthanasia, and argue that mercy killing should be regarded as analogous to positive rather than negative cases. (...) On the basis of this, I then support active rather than passive euthanasia. (shrink)

The aim of UK-REACH (“The United Kingdom Research study into Ethnicity And COVID-19 outcomes in Healthcare workers”) is to understand if, how, and why healthcare workers (HCWs) in the United Kingdom (UK) from ethnic minority groups are at increased risk of poor outcomes from COVID-19. In this article, we present findings from the ethical and legal stream of the study, which undertook qualitative research seeking to understand and address legal, ethical, and social acceptability issues around data protection, privacy, and information (...) governance associated with the linkage of HCWs’ registration data and healthcare data. We interviewed 22 key opinion leaders in healthcare and health research from across the UK in two-to-one semi-structured interviews. Transcripts were coded using qualitative thematic analysis. Participants told us that a significant aspect of Big Data research in public health is varying drivers of mistrust—of the research itself, research staff and funders, and broader concerns of mistrust within participant communities, particularly in the context of COVID-19 and those situated in more marginalised community settings. However, despite the challenges, participants also identified ways in which legally compliant and ethically informed approaches to research can be crafted to mitigate or overcome mistrust and establish greater confidence in Big Data public health research. Overall, our research indicates that a “Big Data Ethics by Design” approach to research in this area can help assure (1) that meaningful community and participant engagement is taking place and that extant challenges are addressed, and (2) that any new challenges or hitherto unknown unknowns can be rapidly and properly considered to ensure potential (but material) harms are identified and minimised where necessary. Our findings indicate such an approach, in turn, will help drive better scientific breakthroughs that translate into medical innovations and effective public health interventions, which benefit the publics studied, including those who are often marginalised in research.

I argue that an individual has aspects numerically identical with it and each other that nonetheless qualitatively differ from it and each other. This discernibility of identicals does not violate Leibniz's Law, however, which concerns only individuals and is silent about their aspects. They are not in its domain of quantification. To argue that there are aspects I will appeal to the internal conflicts of conscious beings. I do not mean to imply that aspects are confined to such cases, but (...) the best way to start is to recognize them experientially. We can feel the conflicts within ourselves. In doing so we can feel some of our aspects. I will try to enhance our understanding of the concept of aspect by listing and formalizing some principles for its use. After that I will argue that all sorts of individual things have aspects, not just people who are conflicted. (shrink)

Robert Card has proposed a reasonability view of conscientious objection that asks providers to state the reasons for their objection for evaluation and approval by a review board. Jason Marsh has challenged Card to provide explicit criteria for what makes a conscientious objection reasonable, which he claims will be too difficult a task given that such objections often involve contentious metaphysical or religious claims. Card has responded by outlining standards by which a conscientious objection could be judged reasonable. In this (...) paper, I extend Marsh’s critique to key concepts in the standards outlined by Card such as abortifacient, harm, emergency, and discrimination, showing they can be given radically different interpretations given different metaphysical or religious presumptions. To resolve these conflicting interpretations, a reasonability view of conscientious objection will need more than the criteria outlined by Card, it will need the resources to evaluate the reasonability of metaphysical or religious claims.

The concept of metaphor as primarily a vehicle for conveying ideas, even if unusual ones, seems to me as wrong as the parent idea that a metaphor has a special meaning. I agree with the view that metaphors cannot be paraphrased, but I think this is not because metaphors say something too novel for literal expression but because there is nothing there to paraphrase. Paraphrase, whether possible or not, inappropriate to what is said: we try, in paraphrase, to say it (...) another way. But if I am right, a metaphor doesn't say anything beyond its literal meaning . This is not, of course, to deny that a metaphor has a point, nor that that point can be brought out by using further words. . . . My disagreement is with the explanation of how metaphor works its wonders. To anticipate: I depend on the distinction between what words mean and what they are used to do. I think metaphor belongs exclusively to the domain of use. It is something brought off by the imaginative employment of words and sentences and depends entirely on the ordinary meanings of those words and hence on the ordinary meanings of the sentences they comprise.

This article examines a handful of recent creative works that reflect speculatively on transgender pasts. I argue that each of these creative texts uses ontological interventions to reimagine moments in trans activist history that scholars have narrated only in terms of the attenuation of sociality and of political participation. These works do this by ratifying trans activists’ relations of reciprocity with extraordinary entities that are not often supported by secular and anthropocentric historiographies. Instead of engaging accounts of coalition work with (...) extraterrestrials, nonhuman animals, and magical powers mainly as sites of “subjugated knowledges”, these creative works all consider the political capacitations afforded by trans collaborations with other-than-human agencies. In order to make this argument, I draw from the recent body of anthropological scholarship known as the “new animism,” and consider the absence of commentary on religion and secularism within the Anglo-American posthuman turn. Ultimately, beyond offering alternatives to historical declension narratives about trans activism, these works urge scholars to consider how relations with “subaltern” agentive forces have become increasingly important to disenfranchised communities’ efforts to negotiate the political debilitations of a post-neoliberal world.

Acts of violence and murder have historically proved difficult to accommodate in standard accounts of the formula of universal law (FUL) version of Kant’s Categorical Imperative (CI). In “Murder and Mayhem,” Barbara Herman offers a distinctive account of the status of these acts that is intended to be appropriately didactic in comparison to accounts like the practical contradiction model. I argue that while Herman’s account is a promising one, the distinction she makes between coercive and non-coercive violence and her response (...) to concerns with the classification of the latter as imperfect duties raise significant questions about the status of some duties. I suggest that we look, instead, to Kant’s treatment of suicide in The Metaphysics of Morals for an account of norms of non-violence and, in particular, to the connection between this duty and concerns with inner freedom and moral health. I argue that we can use this account to inform our general understanding of duties prohibiting killing and violence, and that the resulting account is a promising one. (shrink)

Novel assisted reproductive technologies (ART) are poised to present our society with strange new ethical questions, such as whether lesbian, gay, bisexual, and transgender (LGBT) couples should be allowed to produce children biologically related to both parents, or whether trans‐women who want to experience childbirth should be allowed to receive uterine transplants. Clinicians opposed to offering such technologies to LGBT couples on moral grounds are likely to seek legal shelter through the conscience clauses enshrined in U.S. law. This paper begins (...) by briefly discussing some novel ART on the horizon and noting that it is unclear whether current conscience clauses will permit fertility clinics to deny such services to LGBT individuals. A compromise approach to conscience is any view that sees the value of respecting conscience claims within limits. I describe and critique the constraints proposed in the recent work of Wicclair, NeJaime and Siegel as ultimately begging the question. My purpose is to strengthen their arguments by suggesting that in the controversial situations that elicit claims of conscience, bioethicists should engage with the metaphysical claims in play. I argue that conscience claims against LGBT individuals ought to be constrained because the underlying metaphysic—that God has decreed the LGBT lifestyle to be sinful—is highly implausible from the perspective of a naturalized metaphysic, which ought to be the lens through which we evaluate conscience claims.

Physiologically accurate mouse models of cancer are critical in the pre‐clinical development of novel cancer therapies. However, current standardized animal‐housing temperatures elicit chronic cold‐associated stress in mice, which is further increased in the presence of tumor. This cold‐stress significantly impacts experimental outcomes. Data from our lab and others suggest standard housing fundamentally alters murine physiology, and this can produce altered immune baselines in tumor and other disease models. Researchers may thus underestimate the efficacy of therapies that are benefitted by immune (...) responses. A potential mediator, norepinephrine, also underlies stress pathways common in mice and humans. Therefore, research into mechanisms connecting cold‐stress and norepinephrine signaling with immune depression in mice could highlight new combination therapies for humans to simultaneously target stress while stimulating anti‐tumor immunity.

Back to the Concrete: A Pragmatist Response to Oppression Pragmatism is a vital tool for society today, both because it addresses our more pressing social problems and because it advances beyond other available solutions. As a good deal of recent European philosophy has shown, as in the cases of Adorno and Agamben, for example, our social life is mediated by abstractions that oppress us. With its focus on the immediacy of experience, pragmatism enables us to overcome these abstractions and return (...) to concrete life in a liberating way. I argue against Agamben, however, that the return to concrete life amounts to anarchism. I show that it leads to liberalism instead, along the lines laid out by Dewey in Liberalism and Social Action, in which freed individuality is compatible with the exercise of social intelligence and planning.
