Two decades ago, East European state socialism met with a paradoxical fate. Between 1989 and 1991, communist party hegemony was abolished, leaving the very idea of socialism permanently discredited—or so it seemed. Yet in the decade that followed, “socialistic” principles and practices would retain—or perhaps acquire—a surprising degree of popular appeal. Was this a cultural legacy of systematic indoctrination? A strategic response to material insecurities? Perhaps a combination of both? In this article, it is argued that many previous efforts to (...) unravel the paradox are inadequate because they ignore both the “strategic” dimensions of culture and the cultural dimensions of instrumental reason. Using life-history data on the former East Germany, it is shown that apparently discredited ideologies can acquire renewed salience in the wake of regime change if they (1) remain culturally available as strategies of action that (2) provided material opportunities or symbolic privileges in the past, and (3) promise to ameliorate new problems engendered by alternative strategies.

Numerous social, economic and academic pressures can have a negative impact on representations of biomedical research. We review several of the forces playing an increasingly pernicious role in how health and science information is interpreted, shared and used, drawing discussions towards the role of narrative. In turn, we explore how aspects of narrative are used in different social contexts and communication environments, and present creative responses that may help counter the negative trends. As traditional methods of communication have in many (...) ways failed the public, changes in approach are required, including the creative use of narratives. (shrink)

Widely hailed as one of the most significant works in modern political philosophy, John Rawls's _Political Liberalism_ defended a powerful vision of society that respects reasonable ways of life, both religious and secular. These core values have never been more critical as anxiety grows over political and religious difference and new restrictions are placed on peaceful protest and individual expression. This anthology of original essays suggests new, groundbreaking applications of Rawls's work in multiple disciplines and contexts. Thom Brooks, Martha Nussbaum, (...) Onora O'Neill, Paul Weithman, Jeremy Waldron, and Frank Michelman explore political liberalism's relevance to the challenges of multiculturalism, the relationship between the state and religion, the struggle for political legitimacy, and the capabilities approach. Extending Rawls's progressive thought to the fields of law, economics, and public reason, this book helps advance the project of a free society that thrives despite disagreements over religious and moral views.

This book is a series of essays by distinguished scholars concerned with the improvement of primary, secondary, and tertiary studies, most especially in arts but also in mathematics and science. It is concerned with past ideas about education in Australia, most particularly with the traditions that have yielded an education that has proven most beneficial to Australia in terms of comparison with other countries; and it advocates and emphasises how this tradition can be maintained and improved in specific ways. Essays (...) focus on primary and secondary education in music, and art, mathematics, history and the classics, on the improvement of memory and vocabulary, but more particularly on university education, discussing the purpose of education, learning in general, the use of the seminar, the necessity of freedom of debate, the inadequacies and contradictions of French and Anglo-post modernism, the teaching of history, of philosophy, and its branch aesthetics, mathematics, equality in education, teaching at university and funding of the whole enterprise. The authors are all well known in their disciplines and some are experts, internationally recognised in their fields. This book features essays by: David Daintree, Karl Schmude, Simon Haines, Kevin Donnelly, Matthew Lesh, Chris Berg & Bella d'Abrera, David Furse-Roberts, Greg Melleuish, Steven Schwartz, Blaise Joseph, James Franklin, Christopher Allen, Richard Gill, Jeremy Bell, Barry Spurr, David Brooks, Natalie Kennedy, Sarah Williams, Sarah Lawrence, Ivan Francis Head.

Political theory is a field that finds nourishment in others. From economics, history, sociology, psychology, and political science, theorists have drawn a rich repertoire of schemas to parse the social world and make sense of it. With each of these encounters, new subjects are brought into focus as others recede into the background, ushering a change not only in how questions are tackled but also in what questions are thought worth asking.

We discuss from a philosophical perspective the way in which the normal concept of time might be said to `emerge' in a quantum theory of gravity. After an introduction, we briefly discuss the notion of emergence, without regard to time. We then introduce the search for a quantum theory of gravity ; and review some general interpretative issues about space, time and matter. We then discuss the emergence of time in simple quantum geometrodynamics, and in the Euclidean approach. Section 6 (...) concludes. (shrink)

Philosophers of science have insisted that evidence of underlying mechanisms is required to support claims about the effects of medical interventions. Yet evidence about mechanisms does not feature on dominant evidence-based medicine “hierarchies.” After arguing that only inferences from mechanisms (“mechanistic reasoning”)—not mechanisms themselves—count as evidence, I argue for a middle ground. Mechanistic reasoning is not required to establish causation when we have high-quality controlled studies; moreover, mechanistic reasoning is more problematic than has been assumed. Yet where the problems can (...) be overcome, mechanistic reasoning can and should be used as evidence. (shrink)

This paper describes student outcomes from participating in a week-long out-of-school action civics program designed to increase students’ civic and political competence and engagement. Using analysis from four years of survey data, this paper presents findings related to changes in students’ civic competence as a result of participating in the program, including findings related to both first time and repeat campers. Data revealed that participants experienced gains in half of the civic competence construct variables, with first-time campers experiencing significant gains (...) in five of the civic competence construct variables. Data analysis suggests that iEngage, an action civics summer experience, was effective in increasing elements of students’ civic competence, including their ability to get people to care about a problem, organize and run a meeting, write an opinion letter or contact a media outlet to express their views, and contact an elected official or community leader to address an issue.

We survey some philosophical aspects of the search for a quantum theory of gravity, emphasising how quantum gravity throws into doubt the treatment of spacetime common to the two `ingredient theories' (quantum theory and general relativity), as a 4-dimensional manifold equipped with a Lorentzian metric. After an introduction (Section 1), we briefly review the conceptual problems of the ingredient theories (Section 2) and introduce the enterprise of quantum gravity (Section 3). We then describe how three main research programmes in quantum (...) gravity treat four topics of particular importance: the scope of standard quantum theory; the nature of spacetime; spacetime diffeomorphisms, and the so-called `problem of time' (Section 4). These programmes are the old particle-physics approach, superstring theory, and canonical quantum gravity. By and large, these programmes accept most of the ingredient theories' treatment of spacetime, albeit with a metric with some type of quantum nature; but they also suggest that the treatment has fundamental limitations. This prompts the idea of going further: either by quantizing structures other than the metric, such as the topology; or by regarding such structures as phenomenological. We discuss this in Section 5.

The main aim of this paper is to make a remark about the relation between dualities between theories, as `duality' is understood in physics and equivalence of theories, as `equivalence' is understood in logic and philosophy. The remark is that in physics, two theories can be dual, and accordingly get called `the same theory', though we interpret them as disagreeing---so that they are certainly not equivalent, as `equivalent' is normally understood. So the remark is simple: but, I shall argue, worth (...) stressing---since often neglected. My argument for this is based on the account of duality developed by De Haro: which is illustrated here with several examples, from both elementary physics and string theory. Thus I argue that in some examples, including in string theory, two dual theories disagree in their claims about the world. I also spell out how this remark implies a limitation of proposals to understand theoretical equivalence as either logical equivalence or a weakening of it. (shrink)

The Panopticon project for a model prison obsessed the English philosopher Jeremy Bentham for almost 20 years. In the end, the project came to nothing; the Panopticon was never built. But it is precisely this that makes the Panopticon project the best exemplification of Bentham’s own theory of fictions, according to which non-existent fictitious entities can have all too real effects. There is probably no building that has stirred more philosophical controversy than Bentham’s Panopticon. The Panopticon is not merely, (...) as Foucault thought, “a cruel, ingenious cage”, in which subjects collaborate in their own subjection, but much more—constructing the Panopticon produces not only a prison, but also a god within it. The Panopticon is a machine which on assembly is already inhabited by a ghost. It is through the Panopticon and the closely related theory of fictions that Bentham has made his greatest impact on modern thought; above all, on the theory of power. The Panopticon writings are frequently cited, rarely read. This edition contains the complete “Panopticon Letters”, together with selections from “Panopticon Postscript I” and “Fragment on Ontology”, Bentham’s fullest account of fictions. A comprehensive introduction by Miran Bozovic explores the place of Panopticon in contemporary theoretical debate. (shrink)

Surveying this large field with more amplitude and exactitude than anything else on offer, this book will be important for scholars of the humanities and specialists.

We have two aims. The main one is to expound the idea of renormalization in quantum field theory, with no technical prerequisites. Our motivation is that renormalization is undoubtedly one of the great ideas—and great successes--of twentieth-century physics. Also it has strongly influenced in diverse ways, how physicists conceive of physical theories. So it is of considerable philosophical interest. Second, we will briefly relate renormalization to Ernest Nagel's account of inter-theoretic relations, especially reduction. One theme will be a contrast between (...) two approaches to renormalization. The old approach, which prevailed from ca. 1945 to 1970, treated renormalizability as a necessary condition for being an acceptable quantum field theory. On this approach, it is a piece of great good fortune that high energy physicists can formulate renormalizable quantum field theories that are so empirically successful. But the new approach to renormalization explains why the phenomena we see, at the energies we can access in our particle accelerators, are described by a renormalizable quantum field theory. For whatever non-renormalizable interactions may occur at yet higher energies, they are insignificant at accessible energies. Thus the new approach explains why our best fundamental theories have a feature, viz. renormalizability, which the old approach treated as a selection principle for theories. That is worth saying since philosophers tend to think of scientific explanation as only explaining an individual event, or perhaps a single law, or at most deducing one theory as a special case of another. Here we see a framework in which there is a space of theories. And this framework is powerful enough to deduce that what seemed “manna from heaven” is to be expected: the good fortune is generic. We also maintain that universality, a concept stressed in renormalization theory, is essentially the familiar philosophical idea of multiple realizability; and that it causes no problems for reductions of a Nagelian kind.

I have two main aims. The first is general, and more philosophical. The second is specific, and more closely related to physics. The first aim is to state my general views about laws and causation at different ”levels’. The main task is to understand how the higher levels sustain notions of law and causation that ”ride free’ of reductions to the lower level or levels. I endeavour to relate my views to those of other symposiasts. The second aim is to (...) give a framework for describing dynamics at different levels, emphasizing how the various levels’ dynamics can mesh or fail to mesh. This framework is essentially that of elementary dynamical systems theory. The main idea will be, for simplicity, to work with just two levels, dubbed ”micro’ and ”macro’, which are related by coarse-graining. I use this framework to describe, in part, the first four of Ellis’ five types of top-down causation. (shrink)

In another paper, one of us argued that emergence and reduction are compatible, and presented four examples illustrating both. The main purpose of this paper is to develop this position for the example of phase transitions. We take it that emergence involves behaviour that is novel compared with what is expected: often, what is expected from a theory of the system's microscopic constituents. We take reduction as deduction, aided by appropriate definitions. Then the main idea of our reconciliation of emergence (...) and reduction is that one makes the deduction after taking a limit of an appropriate parameter $N$. Thus our first main claim will be that in some situations, one can deduce a novel behaviour, by taking a limit $N\to\infty$. Our main illustration of this will be Lee-Yang theory. But on the other hand, this does not show that the $N=\infty$ limit is physically real. For our second main claim will be that in such situations, there is a logically weaker, yet still vivid, novel behaviour that occurs before the limit, i.e. for finite $N$. And it is this weaker behaviour which is physically real. Our main illustration of this will be the renormalization group description of cross-over phenomena. (shrink)

Abstract: This paper assesses the Everettian approach to the measurement problem, especially the version of that approach advocated by Simon Saunders and David Wallace. I emphasise conceptual, indeed metaphysical, aspects rather than technical ones; but I include an introductory exposition of decoherence. In particular, I discuss whether---as these authors maintain---it is acceptable to have no precise definition of 'branch' (in the Everettian kind of sense). (A version of this paper will appear in a CTNS/Vatican Observatory volume on Quantum Theory and (...) Divine Action, ed. Robert Russell et al.). (shrink)

This paper expounds the modern theory of symplectic reduction in finite-dimensional Hamiltonian mechanics. This theory generalizes the well-known connection between continuous symmetries and conserved quantities, i.e. Noether's theorem. It also illustrates one of mechanics' grand themes: exploiting a symmetry so as to reduce the number of variables needed to treat a problem. The exposition emphasises how the theory provides insights about the rotation group and the rigid body. The theory's device of quotienting a state space also casts light on philosophical (...) issues about whether two apparently distinct but utterly indiscernible possibilities should be ruled to be one and the same. These issues are illustrated using ``relationist'' mechanics. (shrink)

Since the late 1990s, the use of contralateral prophylactic mastectomy to treat unilateral breast cancer has been on the rise. Over the past two decades, dozens of studies have been conducted in order to understand this trend, which has puzzled and frustrated physicians who find it at odds with efforts to curb the surgical overtreatment of breast cancer, as well as with evidence-based medicine, which has established that the procedure has little oncologic benefit for most patients. Based on the work (...) of Annemarie Mol and John Law, this paper argues that these efforts to understand increased CPM use are limited by the “epistemology problem” in medicine, or, in other words, the tendency to view healthcare controversies and decision making exclusively through the lenses of objective and subjective forms of knowledge. Drawing on public discourse about rationales for choosing CPM, we argue that this surgical trend cannot adequately be understood in terms of what doctors and patients know about breast cancer risk and how CPM affects that risk. In addition, it must be recognized as the outcome of how specific practices of screening, detection, and treatment do or enact the bodies of patients, producing tensions in their lives that cannot be remedied with better or better communicated information. Recognizing the embodied realities of these enactments and their effects on patient decision making, we maintain, is essential for physicians who want to avoid the paternalism that haunts breast cancer treatment in the US.

This paper presents the relationship between pedagogical content knowledge and political/ideological clarity as a framework for understanding the nuanced interpretations and applications of critical social studies pedagogy and practice. Using a qualitative case study research design, this study explores the decision-making process of two novice social studies teachers as they decide if and how to utilize critical historical inquiry within their classrooms. Findings indicate that teachers’ use of critical historical inquiry is informed by their subject area consciousness and political and (...) ideological clarity which is cultivated through personal, schooling, and communal experiences. However, we also find that a teacher's pedagogy is significantly strengthened when political and ideological clarity are coupled with pedagogical content knowledge to ensure a more developed enactment of critical historical inquiry is reached within the social studies classroom.

Niche construction theory (NCT) can be applied to examine the influence of culturally constructed learning environments on the acquisition and retention of beliefs, values, role expectations, and skills. Thus, NCT provides a quantitative framework to account for cultural-historical contingency affecting development and cultural evolution. Learning in a culturally constructed environment is of central concern to many sociologists, cognitive scientists, and sociocultural anthropologists, albeit often from different perspectives. This article summarizes four pertinent theories from these fields—situated learning, activity theory, practice theory, (...) and distributed cognition. As a basis for interdisciplinary investigation, the article considers how these theories may be addressed using a cultural niche-construction framework, including the utility of an embedded model that explicitly accounts for effects of the constructed learning environment on within-individual learning dynamics in an evolutionary framework.

Summary The object of this study is to analyse certain aspects of the debate between David Brewster and William Whewell concerning the probability of extra-terrestrial life, in order to illustrate the nature, constitution and condition of natural theology in the decades immediately preceding the publication in 1859 of Charles Darwin's Origin of species. The argument is directed against a stylised picture of natural theology which has been drawn from a backward projection of the Darwinian antithesis between natural selection and certain (...) forms of the design argument. Contrary to the popular image of natural theology as an essentially static, autonomous and monolithic set of presuppositions about the existence of design in nature, the paper underlines the existence of a fundamental divergence of strategies within natural theology, a divergence that, in the case of Brewster and Whewell, can be correlated with the religious cultures to which they most closely belonged. The fact that, in the plurality of worlds debate, their respective positions became mutually exclusive suggests that the fragmented and disordered state of natural theology, only too apparent before the Darwinian impact, was occasioned as much by the ulterior problem of rationalising the excessive space of the astronomers and the excessive time of the geologists as it was by any principle of the uniformity of nature in the biological sphere. The argument is substantiated with particular reference to the breakdown in communication as Brewster and Whewell developed conflicting strategies to expose the ?development hypothesis? that had appeared in Vestiges. Their altercation also reveals a certain conflict of status concerning the conclusions of astronomy and geology which, in turn, suggests that tensions between the physical and life sciences were not peculiar to the period following the publication of Darwin's theory.

The purpose of this survey was to gather individual’s attitudes and feelings towards privacy and the selling of data. A total (N) of 1,107 people responded to the survey. -/- Across continents, age, gender, and levels of education, people overwhelmingly think privacy is important. An impressive 82% of respondents deem privacy extremely or very important, and only 1% deem privacy unimportant. Similarly, 88% of participants either agree or strongly agree with the statement that ‘violations to the right to privacy are (...) one of the most important dangers that citizens face in the digital age.’ The great majority of respondents (92%) report having experienced at least one privacy breach. -/- People’s first concern when losing privacy is the possibility that their personal data might be used to steal money from them. Interestingly, in second place in the ranking of concerns, people report being concerned about privacy because ‘Privacy is a good in itself, above and beyond the consequences it may have.’ -/- People tend to feel that they cannot trust companies and institutions to protect their privacy and use their personal data in responsible ways. The majority of people believe that governments should not be allowed to collect everyone’s personal data. Privacy is thought to be a right that should not have to be paid for. (shrink)

Background: The current study was designed to examine whether ethnic-racial identity moderated the relationship between disordered eating and primary ethnic identification.Methods: Three hundred and ninety-eight undergraduate women were recruited from a large university in Hawai‘i. Participants completed the Eating Disorder Examination Questionnaire, the ERI measure, and reported their primary ethnicity as an index of ethnicity.Results: There was a significant correlation between eating concerns and centrality, r = 0.127, p < 0.05. Moderation analyses indicated that only ERI centrality moderated the predictive (...) effect of ethnicity on the importance of eating concerns, b = 0.05, t = 2.37, p = 0.018.Conclusions: The results suggest that the relationship between self-reported primary ethnicity and EDEQ scores is greater when ethnicity is more central to the individual's identity or when the in-group affect is important to an individual. Findings underscore the need for further research on the underlying mechanisms that account for the differing ways that ERI may affect eating concerns. (shrink)

The purpose of this paper is to think about the various methods of attempting to make money in the capital markets (“investing”). I suggest that though running a betting system on a Roulette wheel is silly, running a betting system on the capital markets may be a good idea.

I reject Norton and Earman's hole argument that spacetime substantivalism is incompatible with determinism. I reconcile these both technically and philosophically. There is a technical definition of determinism that is not violated by pairs of models of the kind used in the hole argument. And technicalities aside, the basic idea of determinism is not violated if we claim that at most one of the two models represents a possible world. This claim can be justified either by metrical essentialism, or by (...) denying transworld identity for points: I prefer the latter. (shrink)

No contemporary compatibilist account of free will can be complete unless it engages with the consequence argument.

Unfortunately, owing to the opacity of Sellars’s writings on free will, his solution has been neglected. I will reconstruct his view here, demonstrating how it represents a powerful challenge to the consequence argument and tying it to some recent developments in the compatibilist (...) literature.

In The life of Richard Owen by his grandson there is an inference to the effect that Owen had objected to his name being used to authorize various statements that Whewell was drafting in opposition to the Vestiges. The inference is drawn from letters that Whewell wrote to Owen on 13 and 15 February 1845. Corroboration of this would corne from a letter of Owen to Whewell, dated 14 February 1845, if extant. Among the Whewell papers at Trinity College, Cambridge, (...) there are several letters from Owen to Whewell, none of which bears that date. There is one, however, dated 14 February 1844 which, on doser inspection, turns out to be the missing link in their correspondance. The evidence for the misdating is not merely that the letter falls naturally into a later sequence. The conclusion is inescapable because Owen refers to an ‘opinion which I have always entertained, and still do strongly, on the subject of a refutation of “Vestiges”’. Since the first edition of Chambers's book did not appear until October 1844, the letter must belong to the following year. My object in this paper is to examine the implications of this letter for a reconstruction of Owen's attitude to that book which Adam Sedgwick could so detest for, among many things, its ‘gross views of physiology’.

We use a reverse Easton forcing iteration to obtain a universe with a definable well-order, while preserving the GCH and proper classes of a variety of very large cardinals. This is achieved by coding using the principle ◊ $_{k^ - }^* $ at a proper class of cardinals k. By choosing the cardinals at which coding occurs sufficiently sparsely, we are able to lift the embeddings witnessing the large cardinal properties without having to meet any non-trivial master conditions.

Background and Objectives People living with dementia have historically been excluded from qualitative research and their voices ignored due to the perception that a person with dementia is not able to express their opinions, preferences and feelings. Research institutions and organizations have contributed by adopting a paternalistic posture of overprotection. Furthermore, traditional research methods have proven to be exclusionary towards this group. The objective of this paper is to address the issue of inclusion of people with dementia in research and (...) provide an evidence-based framework for dementia researchers based on the five principles of human rights: Participation, Accountability, Non-discrimination and equality, Empowerment and Legality (PANEL). Design This paper adapts the PANEL principles to the research context, and uses evidence from the literature to create a framework for qualitative research in people with dementia. This new framework aims to guide dementia researchers in designing studies around the needs of people with dementia, to improve involvement and participation, facilitate research development and maximize research outcomes. Results A checklist is presented with questions related to the five PANEL principles. These questions cover ethical, methodological and legal issues that researchers may need to consider while developing qualitative research for people with dementia. Conclusions The proposed checklist offers a series of questions and considerations to facilitate the development of qualitative research in patients with dementia. It is inspired by current human rights work of recognized dementia researchers and organizations who have been directly involved in policy development. Future studies need to explore its utility in improving participation, facilitating ethics approvals and ensuring that outcomes are relevant to people with dementia. (shrink)

In a previous paper, we have proposed assigning as the value of a physical quantity in quantum theory, a certain kind of set (a sieve) of quantities that are functions of the given quantity. The motivation was in part physical---such a valuation illuminates the Kochen-Specker theorem; and in part mathematical---the valuation arises naturally in the topos theory of presheaves. This paper discusses the conceptual aspects of this proposal. We also undertake two other tasks. First, we explain how the proposed valuations (...) could arise much more generally than just in quantum physics; in particular, they arise as naturally in classical physics. Second, we give another motivation for such valuations (that applies equally to classical and quantum physics). This arises from applying to propositions about the values of physical quantities some general axioms governing partial truth for any kind of proposition. (shrink)

This paper forms part of a wider campaign: to deny pointillisme. That is the doctrine that a physical theory's fundamental quantities are defined at points of space or of spacetime, and represent intrinsic properties of such points or point-sized objects located there; so that properties of spatial or spatiotemporal regions and their material contents are determined by the point-by-point facts. Elsewhere, I argued against pointillisme about chrono-geometry, and about velocity in classical mechanics. In both cases, attention focussed on temporal extrinsicality: (...) i.e. on what an ascription of a property implies about other times. Therefore, I also discussed the metaphysical debate whether persistence should be understood as endurance or perdurance. In this paper, I focus instead on spatial extrinsicality: i.e. on what an ascription of a property implies about other places. The main idea will be that the classical mechanics of continuous media involves a good deal of spatial extrinsicality---which seems not to have been noticed by philosophers, even those who have no inclination to pointillisme. I begin by describing my wider campaign. Then I present some elementary aspects of stress, strain and elasticity---emphasising the kinds of spatial extrinsicality they each involve. I conduct the discussion entirely in the context of `Newtonian' ideas about space and time. But my arguments carry over to relativistic physics. (shrink)

Vopěnka’s Principle is a natural large cardinal axiom that has recently found applications in category theory and algebraic topology. We show that Vopěnka’s Principle and Vopěnka cardinals are relatively consistent with a broad range of other principles known to be independent of standard (ZFC) set theory, such as the Generalised Continuum Hypothesis, and the existence of a definable well-order on the universe of all sets. We achieve this by showing that they are indestructible under a broad class of forcing constructions, (...) specifically, reverse Easton iterations of increasingly directed closed partial orders.

This paper expounds the relations between continuous symmetries and conserved quantities, i.e. Noether's ``first theorem'', in both the Lagrangian and Hamiltonian frameworks for classical mechanics. This illustrates one of mechanics' grand themes: exploiting a symmetry so as to reduce the number of variables needed to treat a problem. I emphasise that, for both frameworks, the theorem is underpinned by the idea of cyclic coordinates; and that the Hamiltonian theorem is more powerful. The Lagrangian theorem's main ``ingredient'', apart from cyclic coordinates, (...) is the rectification of vector fields afforded by the local existence and uniqueness of solutions to ordinary differential equations. For the Hamiltonian theorem, the main extra ingredients are the asymmetry of the Poisson bracket, and the fact that a vector field generates canonical transformations iff it is Hamiltonian. (shrink)

This paper discusses some of the modal involvements of analytical mechanics. I first review the elementary aspects of the Lagrangian, Hamiltonian and Hamilton-Jacobi approaches. I then discuss two modal involvements; both are related to David Lewis' work on modality, especially on counterfactuals. The first is the way Hamilton-Jacobi theory uses ensembles, i.e. sets of possible initial conditions. The structure of this set of ensembles remains to be explored by philosophers. The second is the way the Lagrangian and Hamiltonian approaches' variational (...) principles state the law of motion by mentioning contralegal dynamical evolutions. This threatens to contravene the principle that any actual truth, in particular an actual law, is made true by actual facts. Though this threat can be avoided, at least for simple mechanical systems, it repays scrutiny; not least because it leads to some open questions. (shrink)

The ambition of this volume is twofold: to provide a comprehensive overview of the field and to serve as an indispensable reference work for anyone who wants to work in it. For example, any philosopher who hopes to make a contribution to the topic of the classical-quantum correspondence will have to begin by consulting Klaas Landsman’s chapter. The organization of this volume, as well as the choice of topics, is based on the conviction that the important problems in the philosophy (...) of physics arise from studying the foundations of the fundamental theories of physics. It follows that there is no sharp line to be drawn between philosophy of physics and physics itself. Some of the best work in the philosophy of physics is being done by physicists, as witnessed by the fact that several of the contributors to the volume are theoretical physicists: viz., Ellis, Emch, Harvey, Landsman, Rovelli, ‘t Hooft, the last of whom is a Nobel laureate.
