Summary In this paper we examine the reaction of the Leiden low-temperature laboratory of Heike Kamerlingh Onnes to new ideas in quantum theory. Especially the contributions of Albert Einstein (1906) and Peter Debye (1912) to the theory of specific heat, and the concept of zero-point energy formulated by Max Planck in 1911, gave a boost to solid state research to test these theories. In the case of specific heat measurements, Kamerlingh Onnes's laboratory faced stiff competition from Walter Nernst's Institute (...) of Physical Chemistry in Berlin. In fact, Berlin got the better of it because Leiden lacked focus. After the liquefaction of helium in 1908, Kamerlingh Onnes transformed his laboratory into an international facility for low temperature research, and for this reason it was impossible to make headway with the specific heat measurements. In the case of zero-point energy, Leiden developed a magnetic research programme to test the concept. Initially the balance of evidence seemed to be tipping in favour of zero-point energy. After 1914, however, Leiden would desert the theory in fovour, of a concept from calssical physics. A curious move that illustrates Kamerlingh Onnes's discomfort with the new quantum theory.

Cet article se donne pour objectif de réfléchir à ce que la crise mondiale du Covid-19 a révélé de nos manières d’habiter les lieux où nous vivons, et parmi celles-ci, la pratique de la danse. La démarche adoptée ici est celle d’un dialogue entre trois courants philosophiques spécifiques : la phénoménologie, le pragmatisme et l’écoféminisme, au sujet de leur conception de l’expérience somatique, à la fois vécue, complexe et ordinaire. Nous cherchons ici les lignes communes à ces trois mouvements philosophiques, (...) dans le but d’esquisser une compréhensions nouvelle du corps, et par extension, une nouvelle approche de la danse par temps de crise pandémique.

The normative mechanics of promising seem complex. The strength and content of promissory obligations, and the residual duties they entail upon being violated, have various prima facie surprising features. We give an account to explain these features. Promises have a point. The point of a promise to φ is a promise-independent reason to φ for the promisee’s sake. A promise turns this reason into a duty. This explains the mechanics of promises. And it grounds a nuanced picture of (...) immoral promises, an argument against promissory bare wrongings, and a constraint on theories of why we have promissory obligations at all. (shrink)

Anthropology from a Pragmatic Point of View essentially reflects the last lectures Kant gave for his annual course in anthropology, which he taught from 1772 until his retirement in 1796. The lectures were published in 1798, with the largest first printing of any of Kant's works. Intended for a broad audience, they reveal not only Kant's unique contribution to the newly emerging discipline of anthropology, but also his desire to offer students a practical view of the world and of (...) humanity's place in it. With its focus on what the human being 'as a free-acting being makes of himself or can and should make of himself,' the Anthropology also offers readers an application of some central elements of Kant's philosophy. This volume offers a new annotated translation of the text by Robert B. Louden, together with an introduction by Manfred Kuehn that explores the context and themes of the lectures. (shrink)

This article outlines how the international push for inclusive education cannot be aligned with current education systems centred on neoliberal ideals of individualism, measurement, and competition. The way that these systems are organised means that a proportion of (usually marginalised) students are necessarily excluded. In order to meaningfully address the global education crisis, that sees millions of children and young people either out of school or unengaged with learning, this ontological misalignment must be acknowledged, and discourse and engagement around it (...) must be promoted. Drawing from the work of Donella Meadows, I argue that ‘high leverage points’ (information flows, rules, system goals, mindsets) are crucial places to intervene in education systems. Intervention at such points, while challenging, has the potential to lead to transformational and sustainable change; change that current ‘low leverage point’ initiatives fail to produce. I conclude with a call for further discourse and research into an examination of ‘high leverage points’ within education systems, how they interact, and how the development of an associated framework would be beneficial for researchers and development partners.

The last three decades have witnessed a heated debate of the merits of intelligent design (ID) as a way to understand a number of observable natural phenomena. The present dispute has its roots in a much older discussion: that of natural theology, which has always had as its goal the discernment of design(s) attributable to God in the natural world. Despite its ongoing relevance, natural theology does not have a coherent scholarly history. Turning Points in Natural Theology from Bacon to (...) Darwin deftly fills that gap, analysing the argument of design during the period from Francis Bacon (1561-1626) to Charles Darwin (1809-82), with a specific focus on those moments at which the rhetorical terms changed significantly.

This essay provides a novel account of iterated epistemic states. The essay argues that states of epistemic determinacy might be secured by countenancing iterated epistemic states on the model of fixed points in the modal $\mu$-calculus. Despite the epistemic indeterminacy witnessed by the invalidation of modal axiom 4 in the sorites paradox -- i.e. the KK principle: $\square$$\phi$ $\rightarrow$ $\square$$\square$$\phi$ -- a hyperintensional epistemic $\mu$-automaton permits fixed points to entrain a principled means by which to iterate epistemic states and account (...) thereby for necessary conditions on self-knowledge. The hyperintensional epistemic $\mu$-calculus is applied to the iteration of the epistemic states of a single agent instead of the common knowledge of a group of agents, and is thus a novel contribution to the literature.

Recent work in philosophy and cognitive science shows that knowledge is the norm of our social practice of assertion, in the sense that an assertion should express knowledge. But why should an assertion express knowledge? I hypothesize that an assertion should express knowledge because the point of assertion is to transmit knowledge. I present evidence supporting this hypothesis.

Y a-t-il une psychanalyse chrétienne? Cette question a-t-elle un sens? Un croyant souffrant doit-il ou non s'assurer que son psychanalyste est lui-même croyant pour protéger sa foi? Autrement dit, comment l'analyse intègre-t-elle ou modifie-t-elle une donnée religieuse? Faire une analyse, c'est accepter de traverser le tragique de sa propre vie. En raison du dévoilement de la vérité que ce processus met en œuvre, le patient voit se dégager devant lui la perspective d'un désir dont la nouvelle mesure est infinie. Ce (...) désir avait été comblé par des objets qui, jusque-là, semblaient le satisfaire. Puis, le symptôme surgit, déstabilise, perturbe les petits arrangements que le patient s'était autorisés. Première ou dernière scène de son tragique? Dans le huis clos théâtral qu'est la séance analytique, le patient-acteur reprend et parle toute son histoire. Comme à son insu, il se voit contraint de redéfinir ce qui donne sens à sa vie : sens religieux? sens éthique? Bref, tout ce qui échappe à l'analyse et que, paradoxe imprévisible, elle évoque et convoque... Pourtant, un point restera toujours aveugle pour lui, à l'instar d'Œdipe qui, les yeux crevés, poursuit son chemin. C'est peut-être en ce même point - tragique-aveugle - que l'homme reconnaît sous une lumière nouvelle que son histoire personnelle rejoint la détresse commune et ordinaire de toute l'humanité.

In this paper, we propose some transfor mations based on the centroid points between single valued neutrosophic numbers. We introduce these trans formations according to truth, indeterminacy and falsity value of single valued neutrosophic numbers. We propose a new similarity measure based on falsity value between single valued neutrosophic sets. Then we prove some properties on new similarity measure based on falsity value between falsity value between single valued neutrosophic sets. Furthermore, we propose similarity measure based on falsity value between (...) single valued neutrosophic sets based on the centroid points of transformed single valued neutrosophic numbers. We also apply the proposed similarity measure between single valued neutrosophic sets to deal with pattern recognition problems. (shrink)

In the literature seeking to explain concepts in terms of their point, talk of ‘the point’ of concepts remains under-theorised. I propose a typology of points which distinguishes practical, evaluative, animating, and inferential points. This allows us to resolve tensions such as that between the ambition of explanations in terms of the points of concepts to be informative and the claim that mastering concepts requires grasping their point; and it allows us to exploit connections between types of (...) points to understand why they come apart, and whether they do so for problematic ideological reasons or for benignly functional reasons.

In this engaging and provocative new book, Lee Eisenberg, bestselling author of The Number, dares to tackle nothing less than what it takes to find enduring meaning and purpose in life. He explains how from a young age, each of us is compelled to take memories of events and relationships and shape them into a one-of-a-kind personal narrative. In addition to sharing his own pivotal memories (some of them moving, some just a shade embarrassing), Eisenberg presents striking research culled from (...) psychology and neuroscience, and draws on insights from a pantheon of thinkers and great writers-Tolstoy, Freud, Joseph Campbell, Virginia Woolf, among others. We also hear from men and women of all ages who are wrestling with the demands of work and family, ever in search of fulfillment and satisfaction. It all adds up to a fascinating story, delightfully told, one that goes straight to the heart of how we explain ourselves to ourselves-in other words, who we are and why. (shrink)

A “conceptual spaces” approach is used to formalize Aristotle’s main intuitions about time and change, and other ideas about temporal points of view. That approach has been used in earlier studies about points of view. Properties of entities are represented by locations in multidimensional conceptual spaces; and concepts of entities are identified with subsets or regions of conceptual spaces. The dimensions of the spaces, called “determinables”, are qualities in a very general sense. A temporal element is introduced by adding a (...) time variable to state functions that map entities into conceptual spaces. That way, states may have some permanency or stability around time instances. Following Aristotle’s intuitions, changes and events will not be necessarily instant phenomena, instead they could be processual and interval dependent. Change is defined relatively to the interval during which the change is taking place. Time intervals themselves are taken to represent points of view. To have a point of view is to look at the world as it is in the selected interval. Many important concepts are relativized to intervals, for instance change, events, identity, ontology, potentiality, etc. The definition of points of view as intervals allows to compare points of view in relation to all these concepts. The conceptual space approach has an immediate semantic and structural character, but it is tempting to develop also logics to describe them. A formal language is introduced to show how this could be done. (shrink)

This volume explores the range of Alfred North Whitehead's philosophy and his relevance to contemporary philosophical traditions.

This paper examines the meaningfulness of pointing in great apes. We appeal to Hannah Ginsborg’s conception of primitive normativity, which provides an adequate criterion for establishing whether a response is meaningful, and we attempt to make room for a conception according to which there is no fundamental difference between the responses of human infants and those of other great apes to pointing gestures. This conception is an alternative to Tomasello’s view that pointing gestures and reactions to them reveal a fundamental (...) difference between humans and other apes. (shrink)

The current standard interpretation of Moore’s proof assumes Moore offers a solution to Kant’s famously posed problem of an external world, which Moore quotes at the start of his 1939 lecture “Proof of an External World.” As a solution to Kant’s problem, Moore’s proof fails utterly. Similarly, a second received interpretation imputes an aim of refuting metaphysical idealism that Moore’s proof does not at all achieve. This study departs from the received interpretations to credit Moore’s stated aim for the proof (...) Moore performed in his 1939 lecture that is to impose a counter-example to an explicitly stated presupposition of Kant’s famously posed problem of an external world. The outcome would therefore subvert Kant’s problem. There is not, however, any rival external world problem that Moore commends in place of Kant’s problem. (shrink)

CHAPTER ONE On the Rhetorical Point of View. Why rhetoric declined, and what remained of it. Once upon a time rhetoric was a vast and influential branch of ...

I have two objectives in this article. The first is methodological: I elaborate a minimal phenomenological method and attempt to show its importance in studies of infant behavior. The second objective is substantive: Applying the minimal phenomenological approach, combined with Meltzoff’s “like-me” developmental framework, I propose the hypothesis that infants learn the pointing gesture at least in part through imitation. I explain how developments in sensorimotor ability (posture, arm and hand control and coordination, and locomotion) in the first year of (...) life prepare the infant for acquiring the pointing gesture. The former may directly enable the latter by allowing the infant to experience its own body as being “like those” of others, thus allowing it to imitatively appropriate a broader range of adult behavior. My proposal emphasizes the embodiment of mind in the development of cognition, contrary to latent dualistic tendencies in some developmental literature. (shrink)

After a period of relative exhaustion, French phenomenology has experienced a powerful revival in the last ten years, with the emer-gence of a “cosmological” paradigm in phenomenology. While this situation is obviously to be welcomed, it also presents contemporary phenomenologists with the challenge of acquiring a compass that will enable them to find their bearings in this rapidly reconfiguring philosophical landscape, and according to principles that still partly elude those who are committed to them. In so doing, the aim of (...) this study is twofold: firstly, to put forward a series of hypotheses as to the way in which it is being structured - and thus to elaborate a typology of contemporary French phenomenologies; and secondly, to attempt to determine the stakes and also the presuppositions of this new philosophical “deal” which, perhaps, remains transitory and, as such, rich in a future that, for the time being, it is only possible to presage.

What does the idea of taking 'the point of view of the universe' tell us about ethics? Lazari-Radek and Singer defend objectivism in ethics, and hedonistic utilitarianism, following Henry Sidgwick's lead. They explore how to justify an ethical theory; conflicts of self-interest and universal benevolence; and whether we should discount the future.

This article is devoted to the problem of ontological foundations of three-dimensional Euclidean geometry. Starting from Bertrand Russell’s intuitions concerning the sensual world we try to show that it is possible to build a foundation for pure geometry by means of the so called regions of space. It is not our intention to present mathematically developed theory, but rather demonstrate basic assumptions, tools and techniques that are used in construction of systems of point-free geometry and topology by means of (...) mereology and Whitehead-like connection structures. We list and briefly analyze axioms for mereological structures, as well as those for connection structures. We argue that mereology is a good tool to model so called spatial relations. We also try to justify our choice of axioms for connection relation. Finally, we briefly discuss two theories: Grzegorczyk’s point-free topology and Tarski’s geometry of solids. (shrink)

Points of view are a central phenomenon in human cognition. Although the concept of point of view is ambiguous, there exist common elements in different notions. A point of view is a certain way to look at things around us. In conceptual points of view, things are looked at or interpreted through conceptual lenses. Conceptual points of view are important for epistemology, cognitive science, and philosophy of science. In this article, a new method to formalize conceptual points of (...) view is introduced. It is based on the conceptual space approach, where concepts are regions of multi-dimensional quality spaces. Points of view, as defined in this article, consist of a selection of relevant dimensions, referred to here as determinables, and of a certain supposition, referred to here as a theory, about the subject content. After considering some early efforts to formalize points of view, the notion of conceptual space is defined and explored. One concept of point of view is defined and developed in the framework of conceptual space, and a new logic for points of view is also outlined. The problem of mind–body correlation is discussed as an example of the application of the notion of points of view. To conclude, the meaning and applications of the new concepts and tools developed in the article are discussed. (shrink)

Euclid’s definition of a point as “that which has no part” has been a major source of controversy in relation to the epistemological and ontological presuppositions of classical geometry, from the medieval and modern disputes on indivisibilism to the full development of point-free geometries in the 20th century. Such theories stem from the general idea that all talk of points as putative lower-dimensional entities must and can be recovered in terms of suitable higher-order constructs involving only extended regions (...) (or bodies). Here I focus on what is arguably the first thorough proposal of this sort, Whitehead’s theory of “extensive abstraction”, offering a critical reconstruction of the theory through its successive installments: from the purely mereological version of ‘La théorie relationniste de l’espace’ (1916) to the refined versions presented in An Enquiry Concerning the Principles of Natural Knowledge (1919) and in The Concept of Nature (1920) to the last, mereotopological version of Process and Reality (1929).

Recent years have seen a certain impatience with John Rawls's approach to political philosophy and calls for the discipline to move beyond it. One source of dissatisfaction is Rawls's idea of a well-ordered society. In a recent article, Alex Schaefer has tried to give further impetus to this movement away from Rawlsian theorizing by pursuing a question about well-ordered societies that he thinks other critics have not thought to ask. He poses that question in the title of his article: “Is (...) Justice a Fixed Point?.” Though Schaefer is critical of Rawlsian political theorizing, I shall contend that his arguments also suggest two paths forward for those who would follow the Rawlsian approach. First, the intellectual devices Schaefer deploys help those who would continue the Rawlsian project to see, and precisely to chart, the next step that that project needs to take—a step necessitated by a concession Rawls himself made late in the development of political liberalism. Second, the clarity and economy with which Schaefer lays out his alternative to the Rawlsian approach make it possible to state some fundamental Rawlsian challenges to a form of theorizing that has considerable appeal to many critics of that approach.

In his paper ``What is Structural Realism?'' James Ladyman drew a distinction between epistemological structural realism and metaphysical (or ontic) structural realism. He also drew a suggestive analogy between the perennial debate between substantivalist and relationalist interpretations of spacetime on the one hand, and the debate about whether quantum mechanics treats identical particles as individuals or as `non-individuals' on the other. In both cases, Ladyman's suggestion is that an ontic structural realist interpretation of the physics might be just what is (...) needed to overcome the stalemate. The main thesis of this paper is that, whatever the interpretative difficulties of generally covariant spacetime physics are, they do not support or suggest structural realism. In particular, I hope to show that there is in fact no analogy that supports a similar interpretation of the metaphysics of spacetime points and of quantum particles. (shrink)

The purpose of this paper is to compare the notion of a Grzegorczyk point introduced in [19] (and thoroughly investigated in [3, 14, 16, 18]) to the standard notions of a filter in Boolean algebras and round filter in Boolean contact algebras. In particular, we compare Grzegorczyk points to filters and ultrafilters of atomic and atomless algebras. We also prove how a certain extra axiom influences topological spaces for Grzegorczyk contact algebras. Last but not least, we do not refrain (...) from a philosophical interpretation of the results from the paper. (shrink)

A. W. Moore argues in this bold, unusual, and ambitious book that it is possible to think about the world from no point of view. His argument involves discussion of a very wide range of fundamental philosophical issues, including the nature of persons, the subject-matter of mathematics, realism and anti-realism, value, the inexpressible, and God. The result is a powerful critique of our own finitude.

A variety of recent work in epistemology employs a notion of normality to provide novel theories of knowledge or justification. While such theories are commonly advertised as affording particularly strong epistemic logics, they often make substantive assumptions about the background notion of normality and its logic. This article takes recent normality-based defences of the KK principle as a case study to submit such assumptions to scrutiny. After clarifying issues regarding the natural language use of normality claims, the article isolates a (...) number of choice points regarding the role of contingency, context-sensitivity and similarity in our theorizing with normality. It turns out that both weaker and stronger logics of normality can be motivated depending on how such choices are resolved. And yet securing logics of normality strong enough for normality to play its envisaged role in epistemology may have unwelcome downstream consequences for the resultant theories of knowledge or justification.
