It is nearly impossible to open a textbook on Newtonian mechanics without encountering the concept of inertial frames: the frames that are privileged by the theory’s dynamics. In this paper, I argue that extant definitions of inertial frames are unsatisfactory. I criticise two common definitions of inertial frames: law-based definitions, according to which inertial frames are simply those in which the laws are true, and structure-based definitions, according to which inertial frames are those that are ‘adapted’ to spatiotemporal structure. I (...) then offer a new, symmetry-based definition of inertial frames. This definition offers a non-conventional way of specifying the dynamically privileged frames. The result clarifies the foundations of Newtonian mechanics and accounts for the empirical success of coordinate-dependent formulations of it. (shrink)

It is now standard to interpret symmetry-related models of physical theories as representing the same state of affairs. Recently, a debate has sprung up around the question when this interpretational move is warranted. In particular, Møller-Nielsen :1253–1264, 2017) has argued that one is only allowed to interpret symmetry-related models as physically equivalent when one has a characterisation of their common content. I disambiguate two versions of this claim. On the first, a perspicuous interpretation is required: an account of the models’ (...) common ontology. On the second, stricter, version of this claim, a perspicuous formalism is required in addition: one whose mathematical structures ‘intrinsically’ represent the physical world, in the sense of Field. Using Dewar’s :485–521, 2019) distinction between internal and external sophistication as a case study, I argue that the second requirement is decisive. This clarifies the conditions under which it is warranted to interpret symmetry-related models as physically equivalent. (shrink)

The presence of symmetries in physical theories implies a pernicious form of underdetermination. In order to avoid this theoretical vice, philosophers often espouse a principle called Leibniz Equivalence, which states that symmetry-related models represent the same state of affairs. Moreover, philosophers have claimed that the existence of non-trivial symmetries motivates us to accept the Invariance Principle, which states that quantities that vary under a theory’s symmetries aren’t physically real. Leibniz Equivalence and the Invariance Principle are often seen as part of (...) the same package. I argue that this is a mistake: Leibniz Equivalence and the Invariance Principle are orthogonal to each other. This means that it is possible to hold that symmetry-related models represent the same state of affairs whilst having a realist attitude towards variant quantities. Various arguments have been presented in favour of the Invariance Principle: a rejection of the Invariance Principle is inter alia supposed to cause indeterminism, undetectability or failure of reference. I respond that these arguments at best support Leibniz Equivalence. (shrink)

Shifts are a well-known feature of the literature on spacetime symmetries. Recently, discussions have focused on so-called dynamic shifts, which by analogy with static and kinematic shifts enact arbitrary linear accelerations of all matter (as well as a change in the gravitational potential). But in mathematical formulations of these shifts, the analogy breaks down: while static and kinematic shift act on the matter field, the dynamic shift acts on spacetime structure instead. I formulate a different, `active' version of the dynamic (...) shift which does act on matter. (shrink)

ABSTRACT In this journal, Middleton and Murgueitio Ramírez argue that absolute velocity is measurable, contrary to the received wisdom. Specifically, they claim that ‘there exists at least one reasonable analysis of measurement according to which the speedometer in [a world called “the Basic World”] measures the absolute velocity of the car.’ In this note, I critically respond to that claim: the analysis of measurement that Middleton and Murgueitio Ramírez propose is not reasonable; nor does it entail that absolute velocities are (...) measurable.

Ruetsche ([2011]) argues that the occurrence of unitarily inequivalent representations in quantum theories with infinitely many degrees of freedom poses a novel interpretational problem. According to Ruetsche, such theories compel us to reject the so-called ideal of pristine interpretation; she puts forward the ‘coalescence approach’ as an alternative. In this paper I offer a novel defence of the coalescence approach. The defence rests on the claim that the ideal of pristine interpretation already fails before one considers the peculiarities of QM∞: (...) there are pre-QM∞ parallels to coalescence. Despite this departure from pristinism, the ‘modest’ view that emerges poses no threat to scientific realism. (shrink)

The distinction between dimensions and units in physics is commonplace. But are dimensions a feature of reality? The most widely-held view is that they are no more than a tool for keeping track of the values of quantities under a change of units. This anti-realist position is supported by an argument from underdetermination: one can assign dimensions to quantities in many different ways, all of which are empirically equivalent. In contrast, I defend a form of dimensional realism, on which some (...) assignments of dimensions to quantities better describe reality than others. The argument I provide is a form of inference to the best explanation. In particular, the technique of dimensional analysis is explanatory, but it is only successful for certain systems of dimensions. Since these dimensional systems support scientific explanations, we have reason to believe that they are real. (shrink)

Physics presents us with a symphony of natural constants: G, h, c, etc. Up to this point, constants have received comparatively little philosophical attention. In this paper I provide an account of dimensionful constants, in particular the gravitational constant. I propose that they represent inter-quantity structure in the form of relations between quantities with different dimensions. I use this account of G to settle a debate over whether mass scalings are symmetries of Newtonian Gravitation. I argue that they are not, (...) but only if we interpret mass anti-quidditistically. This is analogous to anti-haecceitism in the presence of spacetime symmetries. (shrink)

- Emilie du Châtelet offers an interesting and unusual account of the origin of our representation of extension. - She is an idealist about the essence extension, bodies and space, regarding them as mental constructs. - Du Châtelet's account requires a brute fact about the mind, in apparent tension with the Principle of Sufficient Reason.

It is often claimed that one can avoid the kind of underdetermination that is a typical consequence of symmetries in physics by stipulating that symmetry-related models represent the same state of affairs (Leibniz Equivalence). But recent commentators (Dasgupta 2011; Pooley 2021; Pooley and Read 2021; Teitel 2021a) have responded that claims about the representational capacities of models are irrelevant to the issue of underdetermination, which concerns possible worlds themselves. In this paper I distinguish two versions of this objection: (1) that (...) a theory’s formalism does not (fully) determine the space of physical possibilities, and (2) that the relevant notion of possibility is not physical possibility. I offer a refutation of each. (shrink)

Recently, Dewar (2019) has suggested that one can apply the strategy of 'sophistication' - as exemplified by sophisticated substantivalism as a response to the diffeomorphism invariance of General Relativity - to gauge theories such as electrodynamics. This requires a shift to the formalism of fibre bundles. In this paper, I develop and defend this suggestion. Where my approach differs from previous discussions is that I focus on the metaphysical picture underlying the fibre bundle formalism. In particular, I aim to affirm (...) the physical reality of gauge properties. I argue that this allows for a local and separable explanation of the Aharonov-Bohm effect. Its puzzling features are explained by a form of holism inherent to fibre bundles. (shrink)

Although physical theories routinely posit absolute quantities, such as absolute position or intrinsic mass, it seems that only comparative quantities such as distance and mass ratio are observable. But even if there are in fact only distances and mass ratios, the success of absolutist theories means that the world looks just as if there are absolute positions and intrinsic masses. If comparativism is nevertheless true, there is a sense in which it is a cosmic conspiracy that the world looks just (...) as if there are absolute quantities: the comparative quantities satisfy certain relations that only absolutism can explain. I show that such cosmic conspiracies are a pervasive feature of comparativist theories. The argument is structurally similar to the well-known No Miracles Argument for scientific realism. Just as anti-realism cannot explain the empirical adequacy of our theories in general, so comparativism cannot explain the empirical adequacy of absolutist theories in particular. (shrink)

The infamous Hole Argument has led philosophers to develop various versions of substantivalism, of which metric essentialism and sophisticated substantivalism are the most popular. In this journal, Trevor Teitel has recently advanced novel arguments against both positions. However, Teitel does not discuss the position of Jeremy Butterfield, which appeals to Lewisian counterpart theory in order to avoid the Hole Argument. In this note I show that the Lewis-Butterfield view is immune to Teitel’s challenges.

Dans un procès qui eut lieu à la fin du XVIIe siècle en Livonie (aujourd’hui Latvia) un homme surnommé « le vieux Thiess » avoua être un loup garou. Les anomalies qui marquent ses aveux ont été l’objet d’interprétations différentes, qui soulèvent le problème des ambitions, et des limites, de la comparaison. L’essai explore, à travers le cas du « vieux Thiess », la possibilité d’utiliser a) la notion d’anomalies conjonctives, inspirée par la critique textuelle, b) la notion de « (...) ressemblances de famille » proposée par Francis Galton, en tant qu’instruments de comparaison dans le domaine de l’histoire des religions.

Intentionality is the power of minds to be about, to represent, or to stand for, things, properties and states of affairs. The puzzles of intentionality lie at the interface between the philosophy of mind and the philosophy of language. The word itself, which is of medieval Scholastic origin, was rehabilitated by the philosopher Franz Brentano towards the end of the nineteenth century. ‘Intentionality’ is a philosopher's word. It derives from the Latin word intentio, which in turn derives from the verb (...) intendere, which means being directed towards some goal or thing. The entry falls into eleven sections. (shrink)

Personal authenticity is out of fashion amongst analytic philosophers. Yet, Kierkegaard, Nietzsche, Heidegger, Sartre and Camus were clearly preoccupied by its theoretical and practical viability. In this study, Jacob Golomb illuminates the writings of these philosophers in an attempt to explain their particular ethical stance on the subject. This book will prove invaluable reading for students and teachers of philosophy, literature and education and indeed for anyone who has ever empathized with Camus's Meursault, Sartre's Matthieu or Nietzsche's Zarathustra.

Some of a person's mental states have the power to represent real and imagined states of affairs: they have semantic properties. What Minds Can Do has two goals: to find a naturalistic or non-semantic basis for the representational powers of a person's mind, and to show that these semantic properties are involved in the causal explanation of the person's behaviour. In the process, this 1997 book addresses issues that are central to much contemporary philosophical debate. It will be of interest (...) to a wide range of readers in philosophy of mind and of language, cognitive science, and psychology. (shrink)

I discuss the views on logic held by three early Nordic neo-Aristotelians — the Swedes Johannes Canuti Lenaeus (1573–1669) and Johannes Rudbeckius (1581–1646), and the Dane Caspar Bartholin (1585–1629). They all studied in Wittenberg (enrolled respectively in 1597, 1601, and 1604) and were exponents of protestant (Lutheran) scholasticism. The works I utilize are Janitores logici bini (1607) and Enchiridion logicum (1608) by Bartholin; Logica (1625) and Controversiae logices (1629) by Rudbeckius; and Logica peripatetica (1633) by Lenaeus. Rudbeckius’s and Lenaeus’s (...) books were published much later than they were prepared. Rudbeckius wrote the first versions of his books in 1606, and the material for Lenaeus’s book had been prepared by 1607. Bartholin calls the treatment of the nature of logic the “first doorkeeper of logic”. To compare the views of the three neo-Aristotelians on this topic, I systematically investigate what they have to say about second notions, the subject of logic, the internal and external goal of logic, and the definition of logic. I also compare their approaches with those of Jacob Martini (teacher of Rudbeckius and Bartholin) and Iacopo Zabarella (an intellectual predecessor of all three). (shrink)

In many eighteenth‐century agricultural texts, peasants were depicted as an impediment to agrarian improvement, superstitious and resistant to novelty. That was the stereotype one often encountered, in any case, in more programmatic writing about agriculture from this period. A closer look at the era's technical literature tells a more complicated story, however. Much as traveling European naturalists relied on local intermediaries in far corners of the globe, elite agricultural improvers back home relied on local rural knowledge as they drafted a (...) new technical literature on farming. This article looks at Jacob Guyer (also known as Kleinjogg), a Swiss farmer who became an enlightened celebrity after the Zurich doctor Hans Caspar Hirzel published a biography of him in 1761. Hirzel called Kleinjogg a “philosophical farmer”; the article explores the implications of this title, and examines the various ways that elite eighteenth‐century authors used contact with rural people and direct experience of farming as a source of authority.

Kant's political philosophy draws a distinction between 'passive' citizens who are merely protected by the law and 'active' citizens who may also contribute to it. Although the distinction between passive and active citizens is often dismissed by scholars as an 'illiberal and undemocratic' relic of eighteenth century prejudice, the distinction is found in every democracy that distinguishes between mere inhabitants -- such as tourists and guestworkers -- and enfranchised citizens. The purpose of this essay is both interpretive and suggestive. First, (...) I will argue that Kant's mature distinction between active and passive citizens follows from an institutional deficiency in the the developing state rather than the natural deficiency of passive citizens, as Kant's critics have alleged. Second, I will draw on systematic features of Kant's political thought in order to claim that the state has a duty to create the institutional conditions of universal active citizenship. (shrink)

Several hypotheses on the form and function of sex differences in social behaviors were tested. The results suggest that friendship preferences in both sexes can be understood in terms of perceived reciprocity potential—capacity and willingness to engage in a mutually beneficial relationship. Divergent social styles may in turn reflect trade-offs between behaviors selected to maintain large, functional coalitions in men and intimate, secure relationships in women. The findings are interpreted from a broad socio-relational framework of the types of behaviors that (...) facilitate selective advertisement and investment of reciprocity potential across individuals and within groups of men and women.

Alva Noë’s version of the enactive conception in _Action in Perception_ is an important contribution to the study of visual perception. First, I argue, however, that it is unclear (at best) whether, as the enactivists claim, work on change blindness supports the denial of the existence of detailed visual representations. Second, I elaborate on what Noë calls the ‘puzzle of perceptual presence’. Thirdly, I question the enactivist account of perceptual constancy. Finally, I draw attention to the tensions between enactivism and (...) two trends in cognitive neuroscience: the two-visual systems model of human vision and the theory of internal forward models of action.

THE FREEHOF INSTITUTE OF PROGRESSIVE HALAKHAH The Freehof Institute of Progressive Halakhah is a creative research center devoted to studying and defining the progressive character of the halakhah in accordance with the principles and theology of Reform Judaism. It seeks to establish the ideological basis of Progressive halakhah, and its application to daily life. The Institute fosters serious studies, and helps scholars in various portions of the world to work together for a common cause. It provides an ongoing forum through (...) symposia, and publications including the quarterly newsletter, HalakhaH, published under the editorship of Walter Jacob, in the United States. The foremost halakhic scholars in the Reform, Liberal, and Progressive rabbinate along with some Conservative and Orthodox colleagues as well as university professors serve on our Academic Council. This collection of essays is the product of the symposia held in Atlanta and Pittsburgh in 1995 and 1996. This book follows the volumes DYNAMIC JEWISH LAW; Progressive Halakhah - Essence and Application (1991), RABBINIC -LAY RELATIONS IN JEWISH LAW (1993), CONVERSION TO JUDAISM IN JEWISH LAW (l994), DEATH AND EUTHANASIA INJEWISH LAW (1995) and THE FETUS AND FERTILITY IN JEWISH LAW (1995), ISRAEL AND THE DIASPORA IN JEWISH LAW (1997). It is part of a series whose subjects are diverse and the approaches taken by the authors are equally so. We wish to encourage wide ranging discussions of contemporary and historic themes. (shrink)

Nobilitas is a study of the history of aristocratic philosophy from ancient Greece to the early twentieth century that aims at providing an alternative to the liberal democratic norms, which are propagated today as the only viable socio-political system for the world community. Jacob reveals that, contrary to popular belief, the social and cultural development of European civilization has, for twenty-five centuries, been based not on democratic or communist notions but, rather on aristocratic and nationalist notions. Beginning with the (...) political philosophies of Plato and Aristotle, and continuing through Renaissance and Baroque aristocratic philosophers, the German Idealists, and English and Italian nationalists, the study ends with the transformation of aristocratic philosophy in nineteenth century Germany into racist elitism. As such, the study includes a survey of the philosophical bases of racism and anti-Semitism. These topics have been systematically excluded from academic and political debate since the end of the last Great War. This study is a pioneering work in understanding and changing political ideologies. (shrink)

Nietzsche described himself as the first psychologist of the West. His interpreters, however, have seldom regarded his works as contributions to psychology. This book gives the psychological perspective a central role and uses it as a guide through Nietzsche's aphoristic maze toward the centre of his thought, method, aims and ramifications. Psychology thus serves as the path to his philosophy and leads to a reconstruction of his substantive theses, including the morality of positive power. By exploring Nietzsche's depth psychology in (...) detail, the book clarifies his basic purpose: to entice readers into uncovering and reactivating their own sources of creative power. (shrink)

I pursue here three related aims. First, I criticise some of the metaphysical claims made on behalf of the so-called `enactive' approach to visual experience. Secondly, I explain why the enactive view of visual experience is hard to square with the evidence in favour of the two-visual-systems model of human vision. Finally, I explore one possible way to develop the `pre-emptive perception' framework and explain why, contrary to first appearances, some of the fundamental discoveries of brain mechanisms, whose function might (...) be to underlie pre-emptive perception, do not really support the enactive approach to visual experience.

Since its inception in 1994, scriptural reasoning has been practiced by academics and religious laypeople on an international scale. Scriptural reasoning is an activity or practice where Jews, Christians, and Muslims read and study together short passages from their traditionally sacred texts. In this book, Jacob L. Goodson describes this activity by giving a tour through modern philosophy and showing how certain arguments, ideas, and theories from modern philosophers help make sense of this inter-religious practice. According to Goodson, one (...) of the most interesting aspects of the practice of scriptural reasoning concerns how its driven by a tension between pragmatism and semiotics—what he calls purposefulness (pragmatism) vs. playfulness (semiotics) throughout the book. Can inter-religious practices only be playful, in terms of an academic “leisure activity”? Or do inter-religious practices need to strive toward a greater end or even a higher purpose, such as peace-making among the Abrahamic faiths or inter-religious friendships? In each individual chapter, Goodson explores this tension within the practice of scriptural reasoning. Utilizing Immanuel Kant’s deontology, Goodson concludes by demonstrating how the practice of scriptural reasoning might work if only two rules are in place while participating in it. (shrink)

Healthcare expenditures account for approximately 9% of GDP in OECD countries and are on an upward trajectory (OECD, 2017). This significant financial burden, combined with an aging global population and increasing demand, emphasizes the imperative for sustained research and innovation to enhance health system efficacy. Key to this transformation are technological advancements, including digital health, which presents novel opportunities for improvement. Emerging digital health technologies, such as virtual consultations, complex imaging procedures, and electronic medical records, are fundamental to modern healthcare (...) infrastructures. However, significant gaps remain in the evaluation and understanding of these innovations, especially for nascent technological areas. This thesis addresses this subject, aiming to delineate how individuals and institutions can bolster their evaluative capabilities, strategic decision-making, and planning for the deployment of emerging digital healthcare technologies. The research methodology amalgamates theoretical exploration, literature scrutiny, and empirical examinations, presenting an integrated perspective that intersects the disciplines of Management & Decision Science, Technology & Innovation, and Health Economics & Outcomes Research. From an applied perspective, this research focuses on developing evidence within the context of pediatric healthcare in Canada — a context notably underrepresented in healthcare management research, despite its disproportionate per capita expenditure. Technologically, the predominant focus is on applications in virtual reality (VR) and three-dimensional (3D) printing and virtualization, though with the aspiration of ensuring the generalizability of results. The current thesis is structured to parallel the progression of the research itself, as three distinct phases; this begins with a comprehensive Background that contextualizes the initial intent, exploring the relationship between technology, innovation, and health outcomes. In this phase, each academic discipline is analyzed to identify base theoretical underpinnings for the research. The second phase of this work includes five empirical studies, each preceded by context-specific literature reviews for the respective technological domain, providing insight into the current state of evidence related to value-based assessment and economic evaluation in that area. Empirical studies included a randomized controlled trial and a cost consequences assessment of VR for pre-procedural preparation for medical imaging. Additionally, novel applications of 3D printing and virtualization are critically analyzed, accompanied by a multi-case study on the implementation of 3D printing in pediatrics, a cost-consequences study of applications for thoracoabdominal surgeries, and an outcomes study on the use of 3D virtualization in medical education during the COVID-19 pandemic. The final phase of this research includes the critical analysis and synthesis of findings into a proposal for a novel value-based assessment and decision-making framework specific to emerging health innovations; this framework integrates insights and resources for clinicians, administrators, and policymakers. The outcomes of this research are skewed toward Knowledge Users, but also aims to advance the theoretical basis for health technology assessment (HTA). (shrink)
