Public health and service delivery programmes, interventions and policies are typically developed and implemented for the primary purpose of effecting change rather than generating knowledge. Nonetheless, evaluations of these programmes may produce valuable learning that helps determine effectiveness and costs as well as informing design and implementation of future programmes. Such studies might be termed ‘opportunistic evaluations’, since they are responsive to emergent opportunities rather than being studies of interventions that are initiated or designed by researchers. However, current ethical guidance (...) and registration procedures make little allowance for scenarios where researchers have played no role in the development or implementation of a programme, but nevertheless plan to conduct a prospective evaluation. We explore the limitations of the guidance and procedures with respect to opportunistic evaluations, providing a number of examples. We propose that one key missing distinction in current guidance is moral responsibility: researchers can only be held accountable for those aspects of a study over which they have control. We argue that requiring researchers to justify an intervention, programme or policy that would occur regardless of their involvement prevents or hinders research in the public interest without providing any further protections to research participants. We recommend that trial consent and ethics procedures allow for a clear separation of responsibilities for the intervention and the evaluation. (shrink)

Background Improving the ways in which routinely-collected mental health data are shared could facilitate substantial advances in research and treatment. However, this process should only be undertaken in partnership with those who provide such data. Despite relatively widespread investigation of public perspectives on health data sharing more generally, there is a lack of research on the views of people with mental illness. Methods Twelve people with lived experience of mental illness took part in semi-structured interviews via online video software. Participants (...) had experience of a broad range of mental health conditions including anxiety, depression, schizophrenia, eating disorders and addiction. Interview questions sought to establish how participants felt about the use of routinely-collected health data for research purposes, covering different types of health data, what health data should be used for, and any concerns around its use. Results Thematic analysis identified four overarching themes: benefits of sharing mental health data, concerns about sharing mental health data, safeguards, and data types. Participants were clear that health data sharing should facilitate improved scientific knowledge and better treatments for mental illness. There were concerns that data misuse could become another way in which individuals and society discriminate against people with mental illness, for example through insurance premiums or employment decisions. Despite this there was a generally positive attitude to sharing mental health data as long as appropriate safeguards were in place. Conclusions There was notable strength of feeling across participants that more should be done to reduce the suffering caused by mental illness, and that this could be partly facilitated by well-managed sharing of health data. The mental health research community could build on this generally positive attitude to mental health data sharing by following rigorous best practice tailored to the specific concerns of people with mental illness.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.1 (2001) 142-143 [Access article in PDF] Wright, John P. and Paul Potter, editors. Psyche and Soma: Physicians and Metaphysicians on the Mind-Body Problem from Antiquity to Enlightenment. New York: Oxford University Press, 2000. Pp. xii + 298. Cloth, $72.00. The mind-body problem has a long history that begins well before Descartes made it extreme by presenting mind as unextended active thinking and (...) matter as unthinking passive extension. This absolute division was motivated in some part by the desire to present the soul as an entity that can survive the death of the body. This is difficult to maintain if the soul is merely the form or the vital force motivating a human body. But the advance of physiology has led more and more to the conclusion that the functions often attributed to the soul are actually carried out by the brain. Thinking may be as natural (and perhaps as determined) a function of the body as is digestion. And if digestion does not survive the death of the body, maybe thinking does not either.This collection of studies provides a detailed introduction to both medical and metaphysical views and theories concerning the relation of mind to body. In particular, the first article by Beate Gundert on Hippocratic Medicine sets the stage by showing that "mind and body in the Hippocratic writings, while distinguished empirically by being related to different types of phenomena, are both ultimately accounted for by the same explanatory model: Human nature (physis), which embraces the totality of bodily structures, physiological processes, and psychic events" (35). T. M. Robinson shows that Plato admits of no solution as to how mind and body interact, and Philip J. van der Eijk argues that "to detach the essence of man completely from his physical make-up would run counter to Aristotle's biological approach to man as a natural living being, the ultimate implication of his view on the divinity of nous is that the fullest realization of what it is to be a human being is to go beyond the limits of corporeality and mortality, and to become, if only temporarily, a god" (77). Heinrich von Staden covers Epicurus, Herophilus, Erasistratus, the Stoics, and Galen, concluding that "The discovery of the nerves entailed the first significant erosion of the vast territory ruled by the soul in Platonic and Aristotelian philosophy, an erosion accompanied by an expansion of the rule of 'nature,' visible not only in medicine, but also in philosophy" (116). Theo K. Heckel discusses Saint Paul's insistence upon the whole person, and Gareth Matthews shows that, prior to Descartes, Augustine presents "a radically new argument for mind-body dualism... an internalist argument... that proceeds from what, allegedly, the mind can know concerning itself to the conclusion that the mind is incorporeal" (145). Emily Michael discusses Pomponazzi's view that we know the immortality of the soul only by faith and the scholastic attempts to show that the soul is a substantial form. Guillaume Lamy, for example, criticized Descartes for having a soul only of thinking, whereas the soul must be of life. Steven Voss shows how at the end of his life, Descartes did discuss in detail how thinking affects the body, particularly in the management of health and the curing of disease. But Descartes does not solve the problem of how this interaction takes place. Thomas Lennon discusses the views of Bayle on Leibniz's monadic forces and Locke's fideism. And Francois Duchesneu continues the discussion of Stahl and Leibniz, to [End Page 142] conclude that "Leibniz attempts to discover the formal foundation of the organism, which he locates in the capacity of perception-appetition proper to the dominant monad" (235).John P. Wright gives an exposition of a very important distinction between Cartesian dualism and the functional dualism that came to dominate medical thought, that is, the question of how the brain and vital organs interact. Roselyn Rey carries this discussion on to the development of theories... (shrink)

Drawing on the 1870s-1880s work of Shadworth Hodgson and Robert Kelly, William James famously characterised the specious present as ‘the short duration of which we are immediately and incessantly sensible’. Literature on the pre-history of late nineteenth century specious present theories clusters around the work of John Locke and Thomas Reid, and I argue it is incomplete. The pre-history is missing an inter-connected group of English philosophers writing on the present between 1749 and 1785: David Hartley, Joseph Priestley, Abraham Tucker, (...) and William Watson. With William Herschel, Watson even conducted experiments to determine the limits of human temporal perception. These thinkers do not appear in the specious present literature, or broader historical surveys of temporal consciousness. Yet this paper shows that they all produced important work on our experience of the present, variously defending theses that can be found in subsequent specious present theories. It argues their texts reward study, and may have influenced later theorists; contextualises the nineteenth century theories of James and others; and pushes back the start date of the 'standard history' of micro time by over half a century.

The Architectonics of Meaning is a lucid demonstration of the purposes, methods, and implications of philosophical semantics that both supports and builds on Richard McKeon's and other noted pluralists' convictions that multiple philosophical approaches are viable. Watson ingeniously explores ways to systematize these approaches, and the result is a well-structured instrument for understanding texts. This book exemplifies both general and particular aspects of systematic pluralism, reorienting our understanding of the realms of knowing, doing, and making.

Artificial intelligence has historically been conceptualized in anthropomorphic terms. Some algorithms deploy biomimetic designs in a deliberate attempt to effect a sort of digital isomorphism of the human brain. Others leverage more general learning strategies that happen to coincide with popular theories of cognitive science and social epistemology. In this paper, I challenge the anthropomorphic credentials of the neural network algorithm, whose similarities to human cognition I argue are vastly overstated and narrowly construed. I submit that three alternative supervised learning (...) methods—namely lasso penalties, bagging, and boosting—offer subtler, more interesting analogies to human reasoning as both an individual and a social phenomenon. Despite the temptation to fall back on anthropomorphic tropes when discussing AI, however, I conclude that such rhetoric is at best misleading and at worst downright dangerous. The impulse to humanize algorithms is an obstacle to properly conceptualizing the ethical challenges posed by emerging technologies. (shrink)

Only by inhabiting Dao (the Way of Nature) and dwelling in its unity can humankind achieve true happiness and freedom, in both life and death. This is Daoist philosophy's central tenet, espoused by the person--or group of people--known as Zhuangzi (369?-286? BCE) in a text by the same name. To be free, individuals must discard rigid distinctions between right and wrong, and follow a course of action not motivated by gain or striving. When one ceases to judge events as good (...) or bad, man-made suffering disappears, and natural suffering is embraced as part of life. Zhuangzi elucidates this mystical philosophy through humor, parable, and anecdote, using non sequitur and even nonsense to illuminate truths beyond the boundaries of ordinary logic. Boldly imaginative and inventively written, the _Zhuangzi_ floats free of its historical period and society, addressing the spiritual nourishment of all people across time. One of the most justly celebrated texts of the Chinese tradition, the _Zhuangzi_ is read by thousands of English-language scholars each year, yet, until now, only in the Wade-Giles romanization. Burton Watson's conversion to pinyin in this book brings the text in line with how Chinese scholars, and an increasing number of other scholars, read it. (shrink)

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealised explanation game in which players collaborate to find the best explanation for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore overlapping causal (...) patterns of variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)

Quantum mechanics is an extraordinarily successful scientific theory. But more than 100 years after it was first introduced, the interpretation of the theory remains controversial. This Element introduces some of the most puzzling questions at the foundations of quantum mechanics and provides an up-to-date and forward-looking survey of the most prominent ways in which physicists and philosophers of physics have attempted to resolve them. Topics covered include nonlocality, contextuality, the reality of the wavefunction and the measurement problem. The discussion is (...) supplemented with descriptions of some of the most important mathematical results from recent work in quantum foundations, including Bell's theorem, the Kochen-Specker theorem and the PBR theorem.

Compiled by disciples of Confucius in the centuries following his death in 479 B.C.E., _The Analects of Confucius_ is a collection of aphorisms and historical anecdotes embodying the basic values of the Confucian tradition: learning, morality, ritual decorum, and filial piety. Reflecting the model eras of Chinese antiquity, the Analects offers valuable insights into successful governance and the ideal organization of society. Filled with humor and sarcasm, it reads like a casual conversation between teacher and student, emphasizing the role of (...) the individual in the attainment of knowledge and the value of using historical events and people to illuminate moral and political concepts. Confucius's teachings focus on cultural and peaceful pursuits and the characteristics of benevolent and culturally distinguished government. He also discusses ancestor worship and other rites performed for the spirits of the dead. The single most influential philosophical work in all of Chinese history, _The Analects of Confucius_ has shaped the thought and customs of China and neighboring countries for centuries. Burton Watson's concise translation uses the pinyin romanization system and keeps explanatory notes to a minimum, yet his intimate knowledge of the Confucian tradition and precise attention to linguistic detail capture the original text's elegance, cogency, and wit.

The first part of the essay explores the relations between the will and practical reason or judgement. The second part takes up decision in the realm of belief, i.e. deciding that such and such is so. This phenomenon raises two questions. Since we decide that as well as to, should we speak of a doxastic will? Secondly, should we regard ourselves as active in the formation of our judgements as in the formation of our intentions? The author's answer to these (...) two further questions is ‘no’ and ‘yes’, respectively: the boundaries between the active and the passive are not marked by the will. (shrink)

Recently there have emerged an assortment of theorems relating to the ‘absoluteness of emerged events,’ and these results have sometimes been used to argue that quantum mechanics may involve some kind of metaphysically radical non-absoluteness, such as relationalism or perspectivalism. However, in our view a close examination of these theorems fails to convincingly support such possibilities. In this paper we argue that the Wigner’s friend paradox, the theorem of Bong et al and the theorem of Lawrence et al are all (...) best understood as demonstrating that if quantum mechanics is universal, and if certain auxiliary assumptions hold, then the world inevitably includes various forms of ‘disaccord,’ but this need not be interpreted in a metaphysically radical way; meanwhile, the theorem of Ormrod and Barrett is best understood either as an argument for an interpretation allowing multiple outcomes per observer, such as the Everett approach, or as a proof that quantum mechanics cannot be universal in the sense relevant for this theorem. We also argue that these theorems taken together suggest interesting possibilities for a different kind of relational approach in which _interaction_ states are relativized whilst observed events are absolute, and we show that although something like ‘retrocausality’ might be needed to make such an approach work, this would be a very special kind of retrocausality which would evade a number of common objections against retrocausality. We conclude that the non-absoluteness theorems may have a significant role to play in helping converge towards an acceptable solution to the measurement problem. (shrink)

Xunzi asserted that the original nature of man is evil, differing on this point from Mencius, his famous predecessor in the Confucian school. In the most complete, well-ordered philosophical system of his day, Xunzi advocated the counteraction of man's evil through self-improvement, the pursuit of learning, the avoidance of obsession, and observance of ritual in life. Readers familiar with Xunzi's work will find that Burton Watson's lucid translation breathes new life into this classic. Those new to Xunzi will find (...) his ideas on government, language, and order and safety in society surprisingly close to concerns of our own age. (shrink)

Postcolonial science studies entails ostensibly contradictory critical and empirical commitments. Science studies scholars influenced by Bruno Latour and Isabelle Stengers embrace forms of realist, radical empiricism, while postcolonial studies scholars influenced by Jacques Derrida trace the limits of the knowable. This essay takes their common use of the term cosmopolitics as an unexpected point of departure for reconciling Derrida’s program with Stengers’s and Latour’s. I read Derrida’s critique of hospitality and Stengers’s and Latour’s ontological politics as necessary complements for conceiving (...) a care-oriented subalternist cosmopolitics, a process of composing common worlds that remains attentive to the limits of representation.

The reference of the postmodern task of thinking is Auschwitz, the abyss and discontinuity separating us from the world of our ancestors. As inhabitants of Planet Auschwitz our point of reference lacks all transcendental warrants; it is not a non-referable reference which constitutes the abyss we must enter, endure, and in which our intellectual and cultural tradition must be transformed. The private/public transformations which constitute the texts of this book attempt to depart from the dystopic individuality and public life resulting (...) from business-as-usual after Auschwitz. The three parts of the book are progressive reworkings of traditional metaphysics as adapted and modified by a modernism that refuses to grapple with its complicity. It is precisely that complicity which postmodern thinking takes up in its attempt to signify otherwise than the easy modernist translations and images of tradition. Thus it is a series of uneasy images imaging otherwise but never apart from modernity that take us away from complicity toward a transformed tradition. The uneasy images of this book are photogrammic combinations of photographs and texts, mutual supplements, pulling tradition through the Event against the persistent and murderous forces of contemporary idolatry and repression.

Simple idealized models seem to provide more understanding than opaque, complex, and hyper-realistic models. However, an increasing number of scientists are going in the opposite direction by utilizing opaque machine learning models to make predictions and draw inferences, suggesting that scientists are opting for models that have less potential for understanding. Are scientists trading understanding for some other epistemic or pragmatic good when they choose a machine learning model? Or are the assumptions behind why minimal models provide understanding misguided? In (...) this paper, using the case of deep neural networks, I argue that it is not the complexity or black box nature of a model that limits how much understanding the model provides. Instead, it is a lack of scientific and empirical evidence supporting the link that connects a model to the target phenomenon that primarily prohibits understanding. (shrink)

The laws of nature have come a long way since the time of Newton: quantum mechanics and relativity have given us good reasons to take seriously the possibility of laws which may be non-local, atemporal, ‘all-at-once,’ retrocausal, or in some other way not well-suited to the standard dynamical time evolution paradigm. Laws of this kind can be accommodated within a Humean approach to lawhood, but many extant non-Humean approaches face significant challenges when we try to apply them to laws outside (...) the time evolution picture. Thus for proponents of non-Humean approaches to lawhood there is a clear need for a novel non-Humean account which is capable of accommodating these sorts of laws. In this paper we propose such an account, characterizing lawhood in terms of constraints, which are understood as a form of modal structure. We demonstrate that our proposed realist account can indeed accommodate a large variety of laws outside the time evolution paradigm, and describe some possible applications to important philosophical problems.

We describe how the set of tools, practices, and social relations known as “precision agriculture” is defined, promoted, and debated. To do so, we perform a critical discourse analysis of popular and trade press websites. Promoters of precision agriculture champion how big data analytics, automated equipment, and decision-support software will optimize yields in the face of narrow margins and public concern about farming’s environmental impacts. At its core, however, the idea of farmers leveraging digital infrastructure in their operations is not (...) new, as agronomic research in this vein has existed for over 30 years. Contemporary discourse in precision ag tends to favour emerging digital technologies themselves over their embeddedness in longstanding precision management approaches. Following several strands of science and technology studies research, we explore what rhetorical emphasis on technical innovation achieves, and argue that this discourse of novelty is a reinvention of precision agriculture in the context of the growing “smart” agricultural economy. We overview six tensions that remain unresolved in this promotional rhetoric, concerning the definitions, history, goals, adoption, uses, and impacts of precision agriculture. We then synthesize these in a discussion of the extent to which digital tools are believed to displace farmer decision-making and whether digital agriculture addresses the biophysical heterogeneity of farm landscapes or land itself has become an “experimental technology”—a way to advance the general development of artificial intelligence. This discussion ultimately helps us name a larger dilemma: that the smart agricultural economy is perhaps less about supporting land and its stewards than promising future tech and profits. (shrink)

Relational quantum mechanics (RQM) is an interpretation of quantum mechanics based on the idea that quantum states do not describe an absolute property of a system but rather a relationship between systems. There have recently been some criticisms of RQM pertaining to issues around intersubjectivity. In this article, we show how RQM can address these criticisms by adding a new postulate which requires that all of the information possessed by a certain observer is stored in physical variables of that observer (...) and thus is accessible by measurement to other observers. This makes it possible for observers to reach intersubjective agreement about quantum events that have occurred in the past. We suggest a possible ontology for a version of RQM employing this postulate; this ontology upholds the principle that quantum states are always relational, but it also postulates a set of quantum events that are not strictly relational. We show that the new postulate helps address the preferred basis problem in RQM. (shrink)

Any successful interpretation of quantum mechanics must explain how our empirical evidence allows us to come to know about quantum mechanics. In this article, we argue that this vital criterion is not met by the class of ‘orthodox interpretations,’ which includes QBism, neo-Copenhagen interpretations, and some versions of relational quantum mechanics. We demonstrate that intersubjectivity fails in radical ways in these approaches, and we explain why intersubjectivity matters for empirical confirmation. We take a detailed look at the way in which (...) belief-updating might work in the kind of universe postulated by an orthodox interpretation, and argue that observers in such a universe are unable to escape their own perspective in order to learn about the structure of the set of perspectives that is supposed to make up reality according to these interpretations. We also argue that in some versions of these interpretations it is not even possible to use one’s own relative frequencies for empirical confirmation. Ultimately we conclude that it cannot be rational to believe these sorts of interpretations unless they are supplemented with some observer-independent structure which underwrites intersubjective agreement in at least certain sorts of cases.

Experiments are commonly thought to have epistemic privilege over simulations. Two ideas underpin this belief: first, experiments generate greater inferential power than simulations, and second, simulations cannot surprise us the way experiments can. In this article I argue that neither of these claims is true of experiments versus simulations in general. We should give up the common practice of resting in-principle judgments about the epistemic value of cases of scientific inquiry on whether we classify those cases as experiments or simulations, (...) per se. To the extent that either methodology puts researchers in a privileged epistemic position, this is context sensitive. (shrink)

Compiling in one volume the basic writings of these three seminal thinkers of ancient China, each from a different philosophical school, this book reveals the richness and diversity of the ancient Chinese intellectual world.

Physicists are increasingly beginning to take seriously the possibility of laws outside the traditional time-evolution paradigm; yet many popular definitions of determinism are still predicated on a time-evolution picture, making them manifestly unsuited to the diverse range of research programmes in modern physics. In this article, we use a constraint-based framework to set out a generalization of determinism which does not presuppose temporal evolution, distinguishing between strong, weak and delocalised holistic determinism. We discuss some interesting consequences of these generalized notions (...) of determinism, and we show that this approach sheds new light on the long-standing debate surrounding the nature of objective chance.

Music as Agency: Diversities of Perspectives on Artistic Citizenship focuses on the concept, application, interpretation and manifestation of Artistic Citizenship in diverse contexts. The key concepts that the book tackles are: Cultural experience, artistic practice, musical identities, equity, democracy, community, activism, resistance and empathy. In giving an overview of aspects of the compound concept of artistic citizenship, Akuno and Westvall present the outcome of research and interrogation of practice by a global network of educator-researchers from Africa, the Americas, Asia and (...) Europe. The book articulates notions of artistic citizenship, coming up with the term artizenship as a derivative of the composite term. It further explains and analyses practical ways of perceiving and relating to art spaces, art practices and arts objects towards belonging, being and becoming in a global space that is disparate, polarised and often alienating, and thus responding to issues such as social justice, identity, participation and inclusion. With a focus on music, the book targets musicians, scholars, educators and enthusiasts keen on gaining a deeper understanding of how music and musicking can influence human interactions towards social integration, trust, cultural awareness and intercultural understanding.

Our in-the-moment experience of the world can feel vivid and rich, even when we cannot describe our experience due to limitations of attention, memory or other cognitive processes. But the nature of visual awareness is quite sparse, as suggested by the phenomena of failures of awareness, such as change blindness and inattentional blindness. I will argue that once failures of memory or failures of comparison are ruled out as explanations for these phenomena, they present strong evidence against rich awareness. To (...) accommodate and explain these massive failures of awareness, any theory of phenomenal consciousness must downgrade phenomenology to a degree where it is functionless or, ironically, does not reflect what we experience.

This collection addresses whether ethicists, like authorities in other fields, can speak as experts in their subject matter. Though ethics consultation is a growing practice in medical contexts, there remain difficult questions about the role of ethicists in professional decision-making. Contributors examine the nature and plausibility of moral expertise, the relationship between character and expertise, the nature and limits of moral authority, how one might become a moral expert, and the trustworthiness of moral testimony. This volume engages with the growing (...) literature in these debates and offers new perspectives from both academics and practitioners. The readings will be of particular interest to bioethicists, clinicians, ethics committees, and students of social epistemology. These new essays promise to advance discussions in the professionalization and accreditation of ethics consultation. (shrink)

Perhaps the most striking phenomenon of visual awareness is inattentional blindness (IB), in which a surprisingly salient event right in front of you may go completely unseen when unattended. Does IB reflect a failure of perception, or only of subsequent memory? Previous work has been unable to answer this question, due to a seemingly intractable dilemma: ruling out memory requires immediate perceptual reports, but soliciting such reports fuels an expectation that eliminates IB. Here we introduce a way of evoking repeated (...) IB in the same subjects and the same session: we show that observers fail to report seeing salient events’ not only when they have no expectation, but also when they have the wrong expectations about the events nature. This occurs when observers must immediately report seeing anything unexpected, even mid-event. Repeated IB thus demonstrates that IB is aptly named: it reflects a genuine deficit in moment-by-moment conscious perception, rather than a form of inattentional amnesia. (shrink)

Standpoint theorists have long been clear that marginalization does not make better understanding a given. They have been less clear, though, that social dominance does not make ignorance a given. Indeed, many standpoint theorists have implicitly committed themselves to what I call the strong epistemic disadvantage thesis. According to this thesis, there are strong, substantive limits on what the socially dominant can know about oppression that they do not personally experience. I argue that this thesis is not just implausible but (...) politically pernicious; it is an excuse for ignorance and silence that stifles our ability to address many injustices. Moreover, I argue that if we are to avoid lending support to the SEDT while working within a standpoint theory framework, we must hold that the socially dominant can achieve marginalized standpoints. So, we must hold that men can achieve feminist standpoints, that white women (and men) can achieve black feminist standpoints, and so on. (shrink)

Social epistemologists should be well-equipped to explain and evaluate the growing vulnerabilities associated with filter bubbles, echo chambers, and group polarization in social media. However, almost all social epistemology has been built for social contexts that involve merely a speaker-hearer dyad. Filter bubbles, echo chambers, and group polarization all presuppose much larger and more complex network structures. In this paper, we lay the groundwork for a properly social epistemology that gives the role and structure of networks their due. In particular, (...) we formally define epistemic constructs that quantify the structural epistemic position of each node within an interconnected network. We argue for the epistemic value of a structure that we call the (m,k)-observer. We then present empirical evidence that (m,k)-observers are rare in social media discussions of controversial topics, which suggests that people suffer from serious problems of epistemic vulnerability. We conclude by arguing that social epistemologists and computer scientists should work together to develop minimal interventions that improve the structure of epistemic networks. (shrink)

In this article we set out to understand the significance of the process matrix formalism and the quantum causal modelling programme for ongoing disputes about the role of causation in fundamental physics. We argue that the process matrix programme has correctly identified a notion of ‘causal order’ which plays an important role in fundamental physics, but this notion is weaker than the common-sense conception of causation because it does not involve asymmetry. We argue that causal order plays an important role (...) in grounding more familiar causal phenomena. Then we apply these conclusions to the causal modelling programme within quantum foundations, arguing that since no-signalling quantum correlations cannot exhibit causal order, they should not be analysed using classical causal models. This resolves an open question about how to interpret fine-tuning in classical causal models of no-signalling correlations. Finally we observe that a quantum generalization of causal modelling can play a similar functional role to standard causal reasoning, but we emphasize that this functional characterisation does not entail that quantum causal models offer novel explanations of quantum processes.

I argue that ML models used in science function as highly idealized toy models. If we treat ML models as a type of highly idealized toy model, then we can deploy standard representational and epistemic strategies from the toy model literature to explain why ML models can still provide epistemic success despite their lack of similarity to their targets.

In recent years the quantum foundations community has seen increasing interest in the possibility of using retrocausality as a route to rejecting the conclusions of Bell’s theorem and restoring locality to quantum physics. On the other hand, it has also been argued that accepting nonlocality leads to a form of retrocausality. In this article we seek to elucidate the relationship between retrocausality and locality. We begin by providing a brief schema of the various ways in which violations of Bell’s inequalities (...) might lead us to consider some form of retrocausality. We then consider some possible motivations for using retrocausality to rescue locality, arguing that none of these motivations is sufficient to show that local retrocausal theories should always be preferred to nonlocal retrocausal theories, and therefore there is no clear reason to focus research efforts entirely on seeking local retrocausal models. Next, we examine several different conceptions of retrocausality, concluding that ‘all-at-once’ retrocausality is more coherent than the alternative dynamical picture. We then argue that since the ‘all-at-once’ approach requires probabilities to be assigned to entire histories, locality is not playing any crucial role within this picture. Thus we conclude that using retrocausality as a way to rescue locality may not be the right route to retrocausality. Finally, we demonstrate that accepting the existence of nonlocality and insisting on the nonexistence of preferred reference frames leads naturally to the acceptance of a form of retrocausality, albeit one which is not mediated by physical systems travelling backwards in time. We argue that this is the more natural way to motivate retrocausal models of quantum mechanics. (shrink)

I argue that the Oxford school Everett interpretation is internally incoherent, because we cannot claim that in an Everettian universe the kinds of reasoning we have used to arrive at our beliefs about quantum mechanics would lead us to form true beliefs. I show that in an Everettian context, the experimental evidence that we have available could not provide empirical confirmation for quantum mechanics, and moreover that we would not even be able to establish reference to the theoretical entities of (...) quantum mechanics. I then consider a range of existing Everettian approaches to the probability problem and show that they do not succeed in overcoming this incoherence. (shrink)
