Cyborg and prosthetic technologies frame prominent posthumanist approaches to understanding the nature of race. But these frameworks struggle to accommodate the phenomena of racial passing and racial travel, and their posthumanist orientation blurs useful distinctions between racialized humans and their social contexts. We advocate, instead, a humanist approach to race, understanding racial hierarchy as an industrial technology. Our approach accommodates racial passing and travel. It integrates a wide array of research across disciplines. It also helpfully distinguishes among grounds of racialization (...) and conditions facilitating impacts of such racialization. (shrink)

In her recent paper ‘The Epistemology of Propaganda’ Rachel McKinnon discusses what she refers to as ‘TERF propaganda’. We take issue with three points in her paper. The first is her rejection of the claim that ‘TERF’ is a misogynistic slur. The second is the examples she presents as commitments of so-called ‘TERFs’, in order to establish that radical (and gender critical) feminists rely on a flawed ideology. The third is her claim that standpoint epistemology can be used to establish (...) that such feminists are wrong to worry about a threat of male violence in relation to trans women. In Section 1 we argue that ‘TERF’ is not a merely descriptive term; that to the extent that McKinnon offers considerations in support of the claim that ‘TERF’ is not a slur, these considerations fail; and that ‘TERF’ is a slur according to several prominent accounts in the contemporary literature. In Section 2, we argue that McKinnon misrepresents the position of gender critical feminists, and in doing so fails to establish the claim that the ideology behind these positions is flawed. In Section 3 we argue that McKinnon’s criticism of Stanley fails, and one implication of this is that those she characterizes as ‘positively privileged’ cannot rely on the standpoint-relative knowledge of those she characterizes as ‘negatively privileged’. We also emphasize in this section McKinnon’s failure to understand and account for multiple axes of oppression, of which the cis/trans axis is only one. (shrink)

One of the key intentions of fresh expressions of church is to reach the kind of people inherited church find it hard to reach. Psychological type profiling of church congregations has demonstrated that Anglican churches have particular difficulty in reaching those whose Jungian judging preference is for thinking rather than for feeling. Studies that have explored the psychological type profile of participants within fresh expressions suggest that they do not significantly differ from inherited congregations in terms of reaching thinking types. (...) Two previous studies, however, have reported higher proportions of thinking types attending cathedral carol services. The present study among 441 individuals attending the Holly Bough service in Liverpool Cathedral also found a higher proportion of thinking types among the participants. These findings suggest that cathedral carol services may be functioning as fresh expressions of church in a significant way.Contribution: Situated within the science of cathedral studies, rooted in psychological type theory, and drawing on data from 441 attendees at the Holly Bough service, this study demonstrates that cathedral services at Christmas are more successful than either inherited church or fresh expressions of church in reaching thinking types.

This chapter briefly reviews the role of race (as a concept) in the history of theorizing the posthuman, engages with existing discussions of race as technology, and explores the significance of understanding race as technology for the field of posthumanism. Our aim is to engage existing literature that posits racialized individuals as posthumans and to consider how studying race might inform theories of the posthuman.

This study is designed to test the hypothesis that events like the Holly Bough service held in Liverpool Cathedral on the fourth Sunday of Advent that attracts a wide range of participants, including regular churchgoers and occasional visitors, contribute significantly to the psychological health and well-being of these participants. At the Holly Bough service held in 2019, a total of 383 participants completed a recognised measure of psychological health and well-being whilst they were waiting for the service to (...) begin and again during a 5-min organ improvisation just before the close of the service. The data demonstrated a significantly higher score on the Oxford Happiness Questionnaire at time 2 than at time 1, suggesting that the experience of the service functioned as an agent of psychological health and well-being.Contribution: Situated within the science of cathedral studies, this paper confirms by means of a repeated-measure study that cathedrals promote psychological health; 383 participants at a Christmas service completed the same well-being measure before and after the service, with a significant increase in scores at time two.

Rudolf Pfeiffer believed that, as a young man, Callimachus wrote four books of Aetia. To these the poet added in his old age a Reply to his Critics , and a slightly revised version of his recent occasional elegy, the Lock of Berenice ; this revised Coma became the last poem in Aetia book 4, to be followed by an Epilogue which may mark a transition to the Iambi. Pfeiffer's theory generally held the field until the brilliant article of P. (...) J. Parsons, in ZPE 25 , 1–50. With the help of newly recovered papyrus fragments Parsons showed that a previously unplaced elegy celebrating a Nemean victory was connected to the story of Molorchus , who entertained Heracles before that hero killed the Nemean lion and instituted the Nemean Games; thus the poem belonged to Aetia book 3. Furthermore, various pieces of evidence converge to make it probable, if not wholly certain, that this substantial poem stood first in its book. So it appears that, at least in the final form of the Aetia, books 3–4 were framed by two poems honouring the wife of Ptolemy III Euergetes, namely Victoria Berenices and Coma Berenices. Soon afterwards a further important advance was made by E. Livrea , who perceived, on grounds of subject-matter as well as papyrology, that the poor man who sets a mousetrap in fr. 177 Pf. must be none other than Molorchus; note particularly the probable mention of Cleonae in fr. 177.37 Pf. = Supplementum Hellenisticum 259.37. Thus a new fragment of 38 lines accrued to the poem. These discoveries have some implications for the composition of the Aetia. Addition of a Coma Berenices to a pre-existent Aetia book 4 could be countenanced easily enough, but, as Parsons says , it would have required a much more radical, and therefore less plausible, revision for Callimachus to have added Victoria Berenices to a pre-existent Aetia book 3. Accordingly Parsons suggested that the original Aetia contained only books 1–2, united by the conversation with the Muses; then in his old age Callimachus compiled two more books, partly at least from poems already composed, and gave them a frame of two poems honouring Queen Berenice. Parsons' view has, I think, been widely accepted; Professor Lloyd-Jones wrote in SIFC 77 , 56 ‘No-one has yet argued against the simple modification of Pfeiffer's theory of the two editions of the Aetia which Mr. Parsons based on this discovery. The first edition comprised two books only.’. (shrink)

Twentieth century philosophers introduced the distinction between “objective rightness” and “subjective rightness” to achieve two primary goals. The first goal is to reduce the paradoxical tension between our judgments of what is best for an agent to do in light of the actual circumstances in which she acts and what is wisest for her to do in light of her mistaken or uncertain beliefs about her circumstances. The second goal is to provide moral guidance to an agent who may be (...) uncertain about the circumstances in which she acts, and hence is unable to use her standard moral principle directly in deciding what to do. This paper distinguishes two important senses of “moral guidance”; proposes criteria of adequacy for accounts of subjective rightness; canvasses existing definitions for “subjective rightness”; finds them all deficient; and proposes a new and more successful account. It argues that each comprehensive moral theory must include multiple principles of subjective rightness to address the epistemic situations of the full range of moral decision-makers, and shows that accounts of subjective rightness formulated in terms of what it would reasonable for the agent to believe cannot provide that guidance.

Recently two distinct forms of rule-utilitarianism have been introduced that differ on how to measure the consequences of rules. Brad Hooker advocates fixed-rate rule-utilitarianism, while Michael Ridge advocates variable-rate rule-utilitarianism. I argue that both of these are inferior to a new proposal, optimum-rate rule-utilitarianism. According to optimum-rate rule-utilitarianism, an ideal code is the code whose optimum acceptance level is no lower than that of any alternative code. I then argue that all three forms of rule-utilitarianism fall prey to two fatal (...) problems that leave us without any viable form of rule-utilitarianism. (shrink)

A moral code consists of principles that assign moral status to individual actions – principles that evaluate acts as right or wrong, prohibited or obligatory, permissible or supererogatory. Many theorists have held that such principles must serve two distinct functions. On the one hand, they serve a theoretical function, insofar as they specify the characteristics in virtue of which acts possess their moral status. On the other hand, they serve a practical function, insofar as they provide an action-guide: a standard (...) by reference to which a person can choose which acts to perform and which not. Although the theoretical and practical functions of moral principles are closely linked, it is not at all obvious that what enables a principle to fill one of these roles automatically equips it to fill the other. In this paper I shall briefly examine some of the reasons why a moral principle might fail to fill its practical role, i.e., be incapable of guiding decisions. I shall then sketch three common responses to this kind of failure, and examine in some detail the adequacy of one of the most popular of these responses. (shrink)

Holly Lawford-Smith argues that gender is not something to be embraced and celebrated, but a system of oppression which should be rejected. She introduces gender-critical feminism, explaining what it means to conceive of gender as norms and to be critical of gender on the basis of that understanding.

In days gone by, when we had something called Rapid Economic Growth, we used to worry about it. We worried especially about its social costs and its technical limits. If growth meant gearing people to efficient production, we would have to be geographically and socially mobile. That threatened our old ways of community life, with their neighbourhood values and extended families. There were more obvious costs too, like chemicals in the air and highways through the landscape. Furthermore, the cornucopia need (...) not be bottomless. To sustain its effusions, nature might have to be pillaged until we ran out of trees or oil. Technology might hit bottlenecks so severe that costs began to outrun benefits. That would mean thwarting the new expectations which economic growth had aroused and which were its motivating force. But, for all that, our island race faced the horrors of affluence, abundance and goodies for all with a stiff upper lip. (shrink)

What should we do if we cannot figure what morality requires of us? Holly M. Smith argues that the best moral codes solve this problem by offering two tiers, one of which tells us what makes acts right and wrong, and the other of which provides user-friendly decision guides. She opens a path towards resolving a deep problem of moral life.

Scientists have used models for hundreds of years as a means of describing phenomena and as a basis for further analogy. In _Scientific Models in Philosophy of Science, _Daniela Bailer-Jones assembles an original and comprehensive philosophical analysis of how models have been used and interpreted in both historical and contemporary contexts. Bailer-Jones delineates the many forms models can take, and how they are put to use. She examines early mechanical models employed by nineteenth-century physicists such as Kelvin and (...) Maxwell, describes their roots in the mathematical principles of Newton and others, and compares them to contemporary mechanistic approaches. Bailer-Jones then views the use of analogy in the late nineteenth century as a means of understanding models and to link different branches of science. She reveals how analogies can also be models themselves, or can help to create them. The first half of the twentieth century saw little mention of models in the literature of logical empiricism. Focusing primarily on theory, logical empiricists believed that models were of temporary importance, flawed, and awaiting correction. The later contesting of logical empiricism, particularly the hypothetico-deductive account of theories, by philosophers such as Mary Hesse, sparked a renewed interest in the importance of models during the 1950s that continues to this day. Bailer-Jones analyzes subsequent propositions of: models as metaphors; Kuhn's concept of a paradigm; the Semantic View of theories; and the case study approaches of Cartwright and Morrison, among others. She then engages current debates on topics such as phenomena versus data, the distinctions between models and theories, the concepts of representation and realism, and the discerning of falsities in models.

For centuries it has been a mainstay of European and American moral thought that keeping promises—and the allied activity of upholding contracts—is one of the most important requirements of morality. On some historically powerful views the obligation to uphold promises or contracts not only regulates private relationships, but also provides the moral foundation for our duty to support and obey legitimate governments. Some theorists believe that the concept of keeping promises has gradually moved to center stage in European moral thought. (...) They see this movement as part of an historical shift from a moral conception in which an individual’s duties are mainly externally imposed and unalterable, to a conception in which duties are largely chosen by the individual.

Even though the evidence‐based medicine movement (EBM) labels mechanisms a low quality form of evidence, consideration of the mechanisms on which medicine relies, and the distinct roles that mechanisms might play in clinical practice, offers a number of insights into EBM itself. In this paper, I examine the connections between EBM and mechanisms from several angles. I diagnose what went wrong in two examples where mechanistic reasoning failed to generate accurate predictions for how a dysfunctional mechanism would respond to intervention. (...) I then use these examples to explain why we should expect this kind of mechanistic reasoning to fail in systematic ways, by situating these failures in terms of evolved complexity of the causal system(s) in question. I argue that there is still a different role in which mechanisms continue to figure as evidence in EBM: namely, in guiding the application of population‐level recommendations to individual patients. Thus, even though the evidence‐based movement rejects one role in which mechanistic reasoning serves as evidence, there are other evidentiary roles for mechanistic reasoning. This renders plausible the claims of some critics of evidencebased medicine who point to the ineliminable role of clinical experience. Clearly specifying the ways in which mechanisms and mechanistic reasoning can be involved in clinical practice frames the discussion about EBM and clinical experience in more fruitful terms.

Rilke's remark conjures up an officious array of well-meaning persons bent on completing our orderly passage from cradle to grave. They tidy our files cosily about us, inject us with extreme unction and slide us into the warm embrace of the undertaker. At the forefront of the array stands the doctor, part mechanic and part priest. His main task is to repair the living with resources whose effective and impartial allocation is a chief topic of medical ethics. But his role (...) is not that of an impartial allocator: his patients want his partisan support. This builds a moral tension into a role played out where system meets patient, and one made instructively plain in the care of the dying. The system no doubt prefers death to be cheap and orderly but this thought may not move someone like Rilke wanting a death of his own. The doctor is then caught between his general duty to patients at large and his particular duty to the patient in front of him, a tension tautened for a Hippocratic promoter of health and life by a patient in search of an exit.

In this field guide, I distinguish five separate senses with which the term ‘mechanism’ is used in contemporary philosophy of science. Many of these senses have overlapping areas of application but involve distinct philosophical claims and characterize the target mechanisms in relevantly different ways. This field guide will clarify the key features of each sense and introduce some main debates, distinguishing those that transpire within a given sense from those that are best understood as concerning distinct senses. The ‘new mechanisms’ (...) sense is at the center of most of these contemporary debates and will be treated at greater length; subsequent senses of mechanism will be primarily distinguished from this one. In part I of this paper, I distinguish two senses of the term ‘mechanism’, both of which are explicitly hierarchical and nested in character, such that any given mechanism is comprised of smaller sub-mechanisms, in turn comprised of yet smaller sub-sub-mechanisms and so on. While both of the senses discussed here are anti-reductive, they differ in their focus on scientific practice versus metaphysics, in the degree of regularity they attribute to mechanisms, and in terms of their relationships to the discussions of mechanisms in the history of philosophy and science.

A finer-grained delineation of a given explanandum reveals a nexus of closely related causal and non- causal explanations, complementing one another in ways that yield further explanatory traction on the phenomenon in question. By taking a narrower construal of what counts as a causal explanation, a new class of distinctively mathematical explanations pops into focus; Lange’s characterization of distinctively mathematical explanations can be extended to cover these. This new class of distinctively mathematical explanations is illustrated with the Lotka-Volterra equations. There (...) are at least two distinct ways those equations might hold of a system, one of which yields straightforwardly causal explanations, but the other of which yields explanations that are distinctively mathematical in terms of nomological strength. In the first, one first picks out a system or class of systems, finds that the equations hold in a causal -explanatory way; in the second, one starts with the equations and explanations that must apply to any system of which the equations hold, and only then turns to the world to see of what, if any, systems it does in fact hold. Using this new way in which a model might hold of a system, I highlight four specific avenues by which causal and non- causal explanations can complement one another. (shrink)

This chapter outlines a novel solution to the problem of the many, according to which objects can be simultaneously constituted by many collections of particles. To support this proposal, it develops a conception of objects that implies it. On this view, objects are fundamentally subjects of change: the changes an object can survive are explanatorily prior to its constitution. From this perspective, PM arises, and objects are multiply constituted because the changes that objects survive are too coarse-grained to distinguish among (...) the many different collections of particles that are candidates for constituting the relevant object.

This paper articulates an account of causation as a collection of information-theoretic relationships between patterns instantiated in the causal nexus. I draw on Dennett’s account of real patterns to characterize potential causal relata as patterns with specific identification criteria and noise tolerance levels, and actual causal relata as those patterns instantiated at some spatiotemporal location in the rich causal nexus as originally developed by Salmon. I develop a representation framework using phase space to precisely characterize causal relata, including their degree (...) of counterfactual robustness, causal profiles, causal connectivity, and privileged grain size. By doing so, I show how the philosophical notion of causation can be rendered in a format that is amenable for direct application of mathematical techniques from information theory such that the resulting informational measures are causal informational measures. This account provides a metaphysics of causation that supports interventionist semantics and causal modeling and discovery techniques. (shrink)

It might surprise someone, who knew only On Liberty, to hear J. S. Mill called the father of British socialism. That would sound a careless bid for a respectable pedigree, on a par with hailing King Canute as father of the British seaside holiday. Mill is passionate there about making the individual a protected species, not to be interfered with even for his own good, unless to prevent harm to others. He is so passionate that government seems at times to (...) have no other task than to protect. The Principles of Political Economy, on the other hand, displays clear, if intermittent, socialist leanings. There too ‘there is a circle round every individual human being, which no government… ought to be permitted to overstep’. But, subject to this constraint, government is urged to do all the utilitarian good it can and some nasty worries for democratic socialists surface instructively. They centre on the social aspects of individuality and give rise to problems in what my title calls the Social Liberty Game. British socialism, with its Lib-Lab origins and tolerant respect for individual liberty, embodies a tension between the rights of each and the good of all, which makes the Principles a living part of its intellectual history.

How regular do mechanisms need to be, in order to count as mechanisms? This paper addresses two arguments for dropping the requirement of regularity from the definition of a mechanism, one motivated by examples from the sciences and the other motivated by metaphysical considerations regarding causation. I defend a broadened regularity requirement on mechanisms that takes the form of a taxonomy of kinds of regularity that mechanisms may exhibit. This taxonomy allows precise explication of the degree and location of regular (...) operation within a mechanism, and highlights the role that various kinds of regularity play in scientific explanation. I defend this regularity requirement in terms of regularity’s role in individuating mechanisms against a background of other causal processes, and by prioritizing mechanisms’ ability to serve as a model of scientific explanation, rather than as a metaphysical account of causation. It is because mechanisms are regular, in the expanded sense described here, that they are capable of supporting the kinds of generalizations that figure prominently in scientific explanations.

This field guide will clarify the key features of each sense and introduce some main debates, distinguishing those that transpire within a given sense from those that are best understood as concerning two distinct senses.

In part II of this field guide, I consider three further senses of the term that are ontologically ‘flat’ or at least not explicitly hierarchical in character: equations in structural equation models of causation, causal-physical processes, and information-theoretic constraints on states available to systems. After characterizing each sense, I clarify its ontological commitments, its methodological implications, how it figures in explanations, its implications for reduction, and the key manners in which it differs from other senses of mechanism. I conclude that there is no substantive core meaning shared by all senses, and that debates in contemporary philosophy of science can benefit from clarification regarding precisely which sense of mechanism is at stake.
