In the recent philosophical literature, several counterexamples to the interpretative principle that symmetry-related models are physically equivalent have been suggested The Oxford handbook of philosophy of physics, Oxford University Press, Oxford, 2013, Noûs 52:946–981, 2018; Fletcher in Found Phys 50:228–249, 2020). Arguments based on these counterexamples can be understood as arguments from scientific practice of roughly the following form: because in scientific practice such-and-such symmetry-related models are treated as representing distinct physical situations, these models indeed represent distinct physical situations. In (...) this paper, a strategy for analysing arguments of this type is presented and applied to the examples that can be found in the literature. I argue that if we are exclusively interested in models understood as representing entire possible worlds, arguments from scientific practice should involve some additional assumptions to guarantee they are relevant for models understood in this way. However, none of the examples presented in the literature satisfy all these additional assumptions, which leads to the conclusion that arguments from scientific practice based on these examples do not undermine the interpretative principle that different symmetry-related models represent the same possible world.

Absolute velocities in Newtonian mechanics are commonly regarded as unmeasurable. Roberts (Br J Philos Sci 59(2):143–168, 2008) provides a justification for this thesis which appeals to the observational indistinguishability of boost-related models of Newtonian mechanics. Middleton and Murgueitio Ramírez (Australas J Philos, 2020) criticise his argumentation by pointing out that his analysis of the notion of measurement is too restrictive, and that, under a weaker analysis (based on counterfactuals), absolute velocities are measurable. Jacobs (Australas J Philos, 2020) opposes their view, (...) arguing that, on a properly formulated counterfactual-based account of measurement, absolute velocities are unmeasurable. However, in his argument, observational indistinguishability plays no role, even though, intuitively, it is very relevant for the issue of (un)measurability. This paper’s aim is to bring observational indistinguishability back to this discussion. I build upon the observation that there is an analogy between possible views on knowledge and justification on the one hand, and on measurement on the other. In particular, I explore the distinction between externalist and internalist approaches. Counterfactual-based accounts are all externalist, whereas the observational indistinguishability of boost-related models becomes relevant if we are interested in an internalist concept of measurement.

The article investigates the relations between Hausdorff and non-Hausdorff manifolds as objects of general relativity. We show that every non-Hausdorff manifold can be seen as a result of gluing together some Hausdorff manifolds. In the light of this result, we investigate a modal interpretation of a non-Hausdorff differential manifold, according to which it represents a bundle of alternative space-times, all of which are compatible with a given initial data set.

In this paper non-Hausdorff manifolds as potential basic objects of General Relativity are investigated. One can distinguish four stages of identifying an appropriate mathematical structure to describe physical systems: kinematic, dynamical, physical reasonability, and empirical. The thesis of this paper is that in the context of General Relativity, non-Hausdorff manifolds pass the first two stages, as they enable one to define the basic notions of differential geometry needed to pose the problem of the evolution-distribution of matter and are not in (...) conflict with the Einstein equations. With regard to the third stage, various potential conflicts with physical reasonability conditions are considered with a tentative conclusion that non-Hausdorff manifolds are more likely to pass this stage than is typically assumed. When dealing with some of these problems, the modal interpretation of non-Hausdorff manifolds is invoked, according to which they represent bundles of alternative possible spacetimes rather than single spacetimes.

In this paper, I argue that the Hole Argument can be formulated without using the notion of isomorphism, and for this reason it is not threatened by the criticism of Halvorson and Manchak (Br J Philos Sci, 2022. https://doi.org/10.1086/719193). Following Earman and Norton (Br J Philos Sci 38, pp. 515–525, 1987), I divide the Hole Argument into two steps: the proof of the Gauge Theorem and the transition from the Gauge Theorem to the conclusion of radical indeterminism. In the analaysis (...) of the first step, I argue that the Gauge Theorem does not rely on the notion of isomorphism but on the notion of the diffeomorphism-invariance of the equations of local spacetime theories; however, for this approach to work, the definition of local spacetime theories needs certain amendments with respect to Earman and Norton’s formulation. In the analysis of the second step, I postulate that we should use the notion of radical indeterminism instead of indeterminism simpliciter and that we should not decide in advance what kind of maps are to be used in comparing models. Instead, we can tentatively choose some kind of maps for this purpose and check whether a given choice leads to radical indeterminism involving empirically indistinguishable models. In this way, the use of the notion of isomorphism is also avoided in the second step of the Hole Argument. A general picture is that physical equivalence can be established by means of an iterative procedure in which we examine various candidate classes of maps, and, depending on the outcomes, we need to broaden or narrow these classes. The Hole Argument can be viewed as a particular instance of this procedure. (shrink)

In this paper, it is argued that, contrary to some suggestions in the philosophical literature, dispositions cannot replace laws in the description of the physical world. If for a certain type of physical situation a well-working law-based account is available, then it is not possible to describe that situation equally well in terms of dispositions. Using an example consisting of four laws (Coulomb’s law, Newton’s law of gravitation, the rule for the composition of forces and Newton’s second law), it is (...) shown that when one attempts to replace a law-based account with a disposition-based account, the latter turns out to be either less informative or inferior with respect to theoretical virtues, such as simplicity, unification, non-triviality of predictions and explanatory power. Laws are also better suited to deal with interactions and their screening off. Using inference to the best explanation, one can conclude from this comparison that it is laws rather than dispositions that should be included in our ontological picture of nature. (shrink)

In the recent philosophical debate about the relationship between symmetries and physical equivalence, two approaches have been distinguished: motivationalism and interpretationalism. In this paper, I point out that there are variants of interpretationalism that have not been taken into account by the proponents of motivationalism. I also argue that some of these overlooked variants of interpretationalism are not prone to the motivationalists’ criticism and overall are the most attractive positions available.

In this paper, I challenge the distinction between “epistemic” and “ontic” states propounded by Harrigan and Spekkens (Found Phys 40:125–157, 2010) by pointing out that because knowledge is factive, any state that represents someone’s knowledge about a physical system thereby also represents something about the physical system itself, so there is no such thing as “mere knowledge”. This criticism leads to the reformulation of the main question of the debate: instead of asking whether a given state is ontic or epistemic, (...) we should instead ask whether a given change of a state is ontic or epistemic. In particular, in the context of quantum mechanics, one can ask whether the collapse of the quantum state could be understood as an epistemically successful change of the observer’s beliefs about the complete state of the system that is not associated with any change in the physical reality. I argue that the answer to this question should be in the negative because it is possible that, in a series of measurements, the collapse rule tells us to update a certain state to a different one and then back to the same state; if both of these updates are merely changes of our beliefs, then they could not both be epistemically successful.

This paper investigates various properties that may by possessed by quantum states, which are believed to be specifically “quantum” and their opposites. It also considers their “absolute” counterparts in the following sense: a given state has a given property absolutely if after an arbitrary unitary transformation it still possesses it. The known relations between the listed properties and between their absolute counterparts are summarized. It is proven that the only two-qubit state that has zero quantum discord absolutely is the maximally (...) mixed state. Finally, related conceptual issues concerning the terms “classical” and “quantum” are discussed. (shrink)

One of the modern approaches to the laws of nature regards them as relations between universals. The most advanced version of such an approach has been presented by D. M. Armstrong. The aim of this paper is to reconstruct and interpret Armstrong’s conception but also to evaluate his theory and to point out what expectations from it are inadequate. My point of reference are two objections to Armstrong’s ideas, namely the problems of identification and inference. I claim that Armstrong’s theory (...) in general and his response to both problems in particular are based on some fundamental metaphysical principles, namely: the principle of identity for universals, the principle of non-contradiction, the relational principle of the indiscernibility of identicals and the principle of contingent necessity. The central part of my interpretation shows how from the laws of nature, properly understood, the occurrence of some states of affairs necessarily results provided that these principles are employed.

This essay responds to the Nancean account of presentation, evoked in the opening citation, in order to trace out in Nancy's enquiries a disruption of Husserlian presentation, and a re-thinking of materiality on the edge of classical phenomenology. It stages a non-encounter between the writings of Jean-Luc Nancy and of Jacques Derrida in relation to a third term, the Lacanian conception of the ‘real’. Thereby it can be shown how these writings touch on each other, in response to phenomenology and (...) to psychoanalytical theory, but do not engage. All the same, the claim to be made is that the writings of Nancy and Derrida converge in forming a third option, alongside the secularised phenomenologies of Sartre and Merleau-Ponty and the Christian phenomenologies of Jean-Luc Marion and Michel Henry, by marking up the event of Lacan's reformulation of Freud's psychoanalytical theorising.

This discussion consists of five sections, beginning with a pair of citations marking up a politics of inclusion, and exclusion in philosophical discussion. The second section, focusing on the first part of this essay’s title, ‘Phenomenological futures in dispute’, locates three inflections of the notion of the future, in the context of an encounter between phenomenology and Marxism. The third section proposes two rewritings of the subtitle, in terms of thematics, as opposed to using proper names as indices for theoretical (...) orientations. The first rewriting retrieves Heidegger’s notions of tradition, as both transmission and inheritance. This opens up a givenness of a futural horizon to alternating versions of futures; the second rewriting then offers modes of evaluating these alternating futures, in a contestation between a patriarchal, a differentiated, and a neutral mode of transmission. A fourth section raises some further questions of methodology, indicating the manner in which a rethinking of religion and of theology returns within phenomenology. In an inconclusive summary, the paper returns to the point of departure, the first version of a relation of non-relation, in a disputed connection to be set out between philosophy, a politics of exclusion, and psychoanalytical accounts of political investment. The paper seeks to locate a relation of non-relation, both in the failed encounters between Jacques Derrida and Jean-Luc Nancy, with respect to phenomenology and its futures, and in the re-emergence, as non-relation, of the formative function within phenomenology of religious precursors, preconditions and commitments.

This essay locates Jean-Luc Nancy's analyses, developed in relation to three invented terms, expeausition, excription, sexistence, in a threefold context: between Immanuel Kant on experience and Heidegger on existence; with Derrida on rethinking life and death ( lavielamort); and as a response to the alteration in phenomenology consequent on a transposition of key themes out of the German speaking context of the analyses of Husserl and Heidegger into the French language context of the French reception. An intensification ( survie) of (...) life forces may arrive in a ‘living on’ ( survivre) where thought processes only partially brought to expression in the lifetimes of their originators acquire precision and definition in moments of extremity, danger and horror, adding a fourth dimension to the initial three.

This book is framed as a dialogue, between Hugo Letiche's iconoclastic appeals to demontrate (as in a demo) for pedagogy/philosophy/politics of (re-)territoralization (as in the demos), and Jacques Rancière's call for dissensus and a new sensibility (le partage du sensible) that may lead to critical democratization.

They champion, affect, hope, poetic narrative, slow science, justice, the commons, engagement and fairness. (shrink)

In this paper, we discuss the processes of racialisation on the example of biomedical research. We argue that applying the concept of racialisation in biomedical research can be much more precise, informative and suitable than currently used categories, such as race and ethnicity. For this purpose, we construct a model of the different processes affecting and co-shaping the racialisation of an individual, and consider these in relation to biomedical research, particularly to studies on hypertension. We finish with a discussion on (...) the potential application of our proposition to institutional guidelines on the use of racial categories in biomedical research. (shrink)

A CHOICE Outstanding Academic Title 2012! Contemporary picturebooks open up spaces for philosophical dialogues between people of all ages. As works of art, picturebooks offer unique opportunities to explore ideas and to create meaning collaboratively. This book considers censorship of certain well-known picturebooks, challenging the assumptions on which this censorship is based. Through a lively exploration of children's responses to these same picturebooks the authors paint a way of working philosophically based on respectful listening and creative and authentic interactions, rather (...) than scripted lessons. This dialogical process challenges much current practice in education. The authors propose that a courageous and critical practice of listening is central to the facilitation of mutually educative dialogue. This book will be of interest to scholars and students of education studies, philosophy of education, literacy teaching and learning, children's literature, childhood and pedagogy. (shrink)

Features include: individual tasks and group activities to (...) promote discussion case studies notes boxes to highlight further reading; chapter overviews and summaries Drawing on readers' own experiences of education, the book reveals the connections between philosophical ideas and educational policy and practice. Part of the Foundations in Education Studies series, this timely textbook is essential reading for students coming to the study of philosophy of education for the first time. (shrink)

The author is in essential agreement with Tallis, that when we only deploy one mode of interpretation, ie the scientific mode, we lose the fundamental realities of human experience, including the experience of free will, on which, ironically, scientific practice depends. Tallis’s philosophical stance is compared to that of Owen Barfield and his work on free will is placed within the context of his other books. A sense of wonder is common to all of them.

This book addresses how people and organisations sometimes respond to uncertainty in making decisions. Those decisions are rooted in beliefs and behaviours that are not always rational, especially in response to perceived randomness, chaos and unexpected circumstances. The author uses a transdisciplinary approach to the study of superstition in the context of business and management, taking care to acknowledge that what is regarded as superstition to one person may well be constructed as a spiritual belief by another. Respect and sensitivity (...) in explicating individual and social constructions of spirituality is a core value in structuring the narrative of the text. The work also explores the interwoven relationships amongst superstition, religion, spirituality and empiricism and how cultural, political, economic and environmental factors are likely to influence organisations and those who are employed by them. Further, it examines the influence of beliefs related to topics such as feng shui, astrology, phrenology and the I Ching in recruitment. This comprehensive treatment of the role of superstition in business will advance the scholarly conversation on uncertainty in decision making. It points to the power of belief that defies empirical validation and how it can be used in a variety of contexts, such as the marketing of products and images to manipulate unwary consumers or inhibit the implementation of health advice in times of COVID-19.

Conferring legal personhood on purely synthetic entities is a very real legal possibility, one under consideration presently by the European Union. We show here that such legislative action would be morally unnecessary and legally troublesome. While AI legal personhood may have some emotional or economic appeal, so do many superficially desirable hazards against which the law protects us. We review the utility and history of legal fictions of personhood, discussing salient precedents where such fictions resulted in abuse or incoherence. We (...) conclude that difficulties in holding “electronic persons” accountable when they violate the rights of others outweigh the highly precarious moral interests that AI legal personhood might protect.

L'oeuvre du philosophe anglais est au coeur du débat qui divise historiens et philosophes sur le thème de la sécularisation de la pensée politique moderne.

Exercise-based rehabilitation forms a key part of the UK National Health Service patient-care pathway for cardiac rehabilitation (CR). Only around half of all eligible patients attend core CR, however, with social inequalities affecting participation. Few qualitative studies have explored in-depth the key factors influencing engagement with CR, specifically from a sociological theoretical, and ethnographic perspective. Utilising an ethnographic approach allowed us to get a sense of the embodied experiences of 10 participants attending or declining core CR, together with a further (...) seven family members/significant others. This provided in-depth appreciation of participants’ lifeworld contexts as key influences on CR participation. The article draws on these qualitative data and focuses on 1) participants’ initial thoughts about CR; and 2) navigating the field of CR, analysed via thematic analysis. We utilise a Bourdieusian theoretical perspective to theorise the findings, including salient socio-cultural factors influencing attendance/non-attendance and (non)adherence. The article findings highlight how perceptions of CR and the ability to navigate the field are strongly influenced by habitus and capital, and how personal biographies and socio-material conditions affect adherence to CR programmes. The study provides original insights into embodied experiences of exercise-based CR, and novel understandings of the reasons for drop-out/poor adherence, theorised from a Bourdieusian perspective.

The question of whether AI systems such as robots can or should be afforded moral agency or patiency is not one amenable either to discovery or simple reasoning, because we as societies constantly reconstruct our artefacts, including our ethical systems. Consequently, the place of AI systems in society is a matter of normative, not descriptive ethics. Here I start from a functionalist assumption, that ethics is the set of behaviour that maintains a society. This assumption allows me to exploit the (...) theoretical biology of sociality and autonomy to explain our moral intuitions. From this grounding I extend to consider possible ethics for maintaining either human- or of artefact-centred societies. I conclude that while constructing AI systems as either moral agents or patients is possible, neither is desirable. In particular, I argue that we are unlikely to construct a coherent ethics in which it it is ethical to afford AI moral subjectivity. We are therefore obliged not to build AI we are obliged to.

Alison Gopnik and her collaborators have recently proposed a bold and intriguing hypothesis about the relationship between scientific cognition and cognitive development in childhood. According to this view, the processes underlying cognitive development in infants and children and the processes underlying scientific cognition are _identical_. We argue that Gopnik’s bold hypothesis is untenable because it, along with much of cognitive science, neglects the many important ways in which human minds are designed to operate within a social environment. This leads to (...) a neglect of _norms_ and the processes of _social_ _transmission_ which have an important effect on scientific cognition and cognition more generally. (shrink)

How leaders and managers respond to not knowing is highly relevant given the complex, ambiguous, and chaotic business environment of the twenty-first century. Drawing on the literature from a variety of disciplines, the paper explores the dominant, unfavorable conceptualization of not knowing. The authors present some potential ethical implications of a negative view of not knowing and suggest how organizations would benefit from identifying any unhelpful aspects of the culture that may encourage unethical, undesirable, and/or hasty actions in situations of (...) not knowing. The paper specifically illustrates how patience, courage, honesty, integrity, and humility are integral to negative capability in the contexts of not knowing. Finally, the paper calls for deeper inquiry into the role of virtue ethics in preparing managers and leaders for not knowing and urges organizations to embrace negative capability in not knowing rather than engaging in damaging delusion.

Everyone knows what is feels like to be in pain. Scraped knees, toothaches, migraines, giving birth, cancer, heart attacks, and heartaches: pain permeates our entire lives. We also witness other people - loved ones - suffering, and we 'feel with' them. It is easy to assume this is the end of the story: 'pain-is-pain-is-pain', and that is all there is to say. But it is not. In fact, the way in which people respond to what they describe as 'painful' has (...) changed considerably over time. In the eighteenth and nineteenth centuries, for example, people believed that pain served a specific (and positive) function - it was a message from God or Nature; it would perfect the spirit. 'Suffer in this life and you wouldn't suffer in the next one'. Submission to pain was required. Nothing could be more removed from twentieth and twenty-first century understandings, where pain is regarded as an unremitting evil to be 'fought'. Focusing on the English-speaking world, this book tells the story of pain since the eighteenth century, addressing fundamental questions about the experience and nature of suffering over the last three centuries. How have those in pain interpreted their suffering - and how have these interpretations changed over time? How have people learnt to conduct themselves when suffering? How do friends and family react? And what about medical professionals: should they immerse themselves in the suffering person or is the best response a kind of professional detachment? (shrink)

Distant Suffering examines the moral and political implications for a spectator of the distant suffering of others as presented through the media. What are the morally acceptable responses to the sight of suffering on television, for example, when the viewer cannot act directly to affect the circumstances in which the suffering takes place? Luc Boltanski argues that spectators can actively involve themselves and others by speaking about what they have seen and how they were affected by it. Developing ideas in (...) Adam Smith's moral theory, he examines three rhetorical 'topics' available for the expression of the spectator's response to suffering: the topics of denunciation and of sentiment and the aesthetic topic. The book concludes with a discussion of a 'crisis of pity' in relation to modern forms of humanitarianism. A possible way out of this crisis is suggested which involves an emphasis and focus on present suffering. (shrink)

There is an abundance of enthusiasm and optimism about how governments at all levels can make use of big data, algorithms and artificial intelligence. There is also growing concern about the risks that come with these new systems. This article makes the case for greater government transparency and accountability about uses of big data through a Government of Canada qualitative research case study. Adapting a method from critical cartographers, I employ counter-mapping to map government big data practices and internal discussions (...) of risk and challenge. I do so by drawing on interviews and freedom of information requests. The analysis reveals that there are more concerns and risks than often publicly discussed and that there are significant areas of silence that need greater attention. The article underlines the need for our democratic systems to respond to our new datafied contexts by ensuring that our institutions make changes to better protect citizen rights, uphold democratic principles and ensure means for citizen intervention.

The universe is the result of a production that pertains not to craft, but to nature. This production does not involve either reasoning or concepts, but is the result of a power that acts on matter like an imprint. The Intellect transmits the intelligible forms it harbors, to the hypostasis Soul, where they become rational formulas. The hypostasis Soul then transmits these rational formulas to the world soul, which produces animate and inanimate beings, as if it had been ordered to (...) do so. Yet since it is the lower part of the soul of the world that is responsible for these productions, its action, which depends on reasons that do not hold the first rank and are drawn from itself, manifests inferior quality, which explains imperfection and the presence of evil in the sensible universe, despite its government by Providence.

What happens when the meaning of life based on a divine revelation no longer makes sense? Does the quest for transcendence end in the pursuit of material success and self-absorption? Luc Ferry argues that modernity and the emergence of secular humanism in Europe since the eighteenth century have not killed the search for meaning and the sacred, or even the idea of God, but rather have transformed both through a dual process: the humanization of the divine and the divinization of (...) the human. Ferry sees evidence for the first of these in the Catholic Church's attempts to counter the growing rejection of dogmatism and to translate the religious tradition into contemporary language. The second he traces to the birth of modern love and humanitarianism, both of which demand a concern for others and even self-sacrifice in defense of values that transcend life itself. Ferry concludes with a powerful statement in favor of what he calls "transcendental humanism"--a concept that for the first time in human history gives us access to a genuine spirituality rooted in human beings instead of the divine.

The Tragedy of the Commons is often associated with an n-person Prisoner’s Dilemma. But it can also have the structure of an n-person Game of Chicken, an Assurance Game, or of a Voting Games (or a Three-in-a-Boat Game). I present three historical stories that document tragedies of the commons, as presented in Aristotle, Mahanarayan and Hume and argue that the descriptions of these historical cases align better with Voting Games than with any other games.

A person who is liable to defensive harm has forfeited his rights against the imposition of the harm, and so is not wronged if that harm is imposed. A number of philosophers, most notably Jeff McMahan, argue for an instrumental account of liability, whereby a person is liable to defensive harm when he is either morally or culpably responsible for an unjust threat of harm to others, and when the imposition of defensive harm is necessary to avert the threatened unjust (...) harm. Others may favour a purely noninstrumental account of liability: one that looks only to the past behaviour of the potentially liable person. We argue that both views are vulnerable to serious objections. Instead we develop and defend a new view of liability to defensive harm: the pluralist account. The pluralist account states that liability to defensive harm has at least two bases. First, if an attacker is morally or culpably responsible for an unjust attack then he has forfeited what we call his agency right, and in doing so he has made himself partially liable to defensive harm. Whether the attacker is fully liable to defensive harm depends, however, on whether the imposition of defensive harm would infringe a different right held by the attacker: his humanitarian right. Humanitarian rights are rights to be provided with urgently needed resources or to be protected from serious harms when others can do so at reasonably low cost. We argue the pluralist account avoids the objections to which the instrumental and noninstrumental views are vulnerable, coheres with our intuitive reactions in a wide range of cases, and sheds new light on the way different rights combine to determine a person's liability to suffer harm.
