It is hypothesized that de Broglie’s ‘matter waves’ provide a dynamical basis for Minkowski spacetime in an antisubstantivalist or relational account. The relativity of simultaneity is seen as an effect of the de Broglie oscillation together with a basic relativity postulate, while the dispersion relation from finite rest mass gives rise to the differentiation of spatial and temporal axes. Thus spacetime is seen as not fundamental, but rather as emergent from the quantum level. A result by Solov’ev which demonstrates that (...) time is not an applicable concept at the quantum level is adduced in support of this claim. Finally, it is noted that de Broglie waves can be seen as the “bridge of becoming” discussed by ( 2005 ). (shrink)

This book of readings would make a superb ancillary text for an advanced or even graduate course in "existential phenomenology." Twelve of the twenty-two selections have been translated for the first time into English. This includes Sartre's defense of the major theses of Being and Nothingness before the Société française de philosophie and Ric£ur's similar defense of La Philosophie de la Volonté, I before the same body. As with Merleau-Ponty's similar defense, "The Primacy of Perception," also included in this volume, (...) the discussion which followed these defenses is presented. Integral texts in the form of articles rather than extracts from books are presented in most cases, including the first appearance of an essay by Marcel entitled "Desire and Hope." Where this is not done, as is partly the case for Strasser and wholly the case for Scheler, Dufrenne, Wild, and Ingarden, lengthy and context-faithful excerpts are given. There are four sections in the book: I. Existence in the Modalities of Consciousness, II. Existence as Embodied, III. Existence and Value, and IV. Existence and the Human Sciences. Each of these sections is skillfully laid out and effectively introduced. In addition to the philosophers mentioned, work by Buytendijk, May, Schutz, Van Kaam, Berger, Bollnow, Minkowski, Straus, and de Waelhens is included. Husserl is missing, as is Heidegger, but these gaps can be supplemented easily enough.—E. A. R. (shrink)

This paper places Julian Schwinger's development of the Euclidean Green's function formalism for quantum field theory in historical context. It traces the techniques employed in the formalism back to Schwinger's work on waveguides during World War II, and his subsequent formulation of the Minkowski space Green's function formalism for quantum field theory in 1951. Particular attention is dedicated to understanding Schwinger's physical motivation for pursuing the Euclidean extension of this formalism in 1958.

Galilean space-time plays the same role in nonrelativistic physics that Minkowski space-time does in relativistic physics. In this paper, the fundamental concepts (velocity, momentum, kinetic energy, etc.) and principles (laws of motion and conservation laws) of classical physics are formulated in the language of Galilean space-time. Much of the development closely parallels the development of similar concepts and principles in the theory of special relativity.

Mach's principle is discussed as a fundamental statement on kinematics, and an apparent contradiction is identified in the Lorentz-Minkowski form of the inertial metric. To resolve the incompatibility, length is redefined so that the speed of light is a field-dependent variable, although still constant for all inertial observers at a point in space-time. Gravitational theories with variableG are considered, and it is shown that a redefinition of length and time results in constantG and variablec.

Purpose. To examine the existential anthropology of G. Marcel and E. Minkowski, in order to demonstrate the necessity of distinguishing the universal-spiritual, as human in human being, apart from the individual-existential in him, and to reveal the hierarchical correlation of biosocial, existential and spiritual spheres in personality. Theoretical basis. Within existential philosophy the author differentiates two separate traditions and proceeds from the insufficiency of the distinction of existential sphere, proposed by phenomenological tradition, showing the necessity of its correlation with the (...) spiritual sphere as a sphere of humanity, proposed by non-phenomenological tradition of G. Marcel and E. Minkowski. Originality. The author presents the anthropological conception of G. Marcel and E. Minkowski, in which human personality is understood as unity of individual-existential and universal-spiritual, which requires a special trans-empirical field of culture, which contains senses, images and symbols of humanity. Also, the author presents the recent developments of existential thinkers in distinguishing existential and spiritual dimensions, both not reducible to the physical and social dimensions. Conclusions. In both existential traditions, the specifically human was founded as a trans-biological and trans-social phenomenon, which appears as indefinable and non-predetermined. But in first tradition, humanity is understood as an existence, as a unique individuality, "project", variant of humanity, equivalent to other variants, and universal is understood as a community of human condition in the world. While in the second tradition, the universal is understood as spiritual. Thus, horizontal level of our private existence, as the process of movement from birth to death, is supplemented by vertical of human, universal ideals and images. Humanity appears as a task, on the way to which human being transcends beyond the limits of his individual "self" to the "super-individual", through inclusion into spiritual community, into universal culture.

The purpose of this paper is twofold: a) to explore the compatibility of Minkowski’s space-time representation of the Special theory of relativity with a dynamic conception of space-time; b) to locate its roots in invariant features - like entropic relations - of the propagation of signals in space-time. From its very beginning Minkowski’s four-dimensional space-time was associated with a static view of reality, e.g. a block universe. Einstein added his influential voice to this conception when he wrote: ‘From a “happening” (...) in three-dimensional space, physics becomes (…) an “existence” in the four-dimensional “world”.’ (Einstein, Relativity 1920, 122) Yet it is by no means clear that Minkowski himself was a believer in the block universe. In his 1908 Cologne lecture on ‘Space and Time’ he speaks of a four-dimensional physics but concedes that a ‘necessary’ time order can be established at every world point. Although the conception of the block universe has gained much currency, an alternative view has been in circulation since the 1910s according to which the trajectories of particles constitute histories in space-time. (Robb 1914, Cunningham 1915, Carathéodorys 1924, Schlick 1917, Reichenbach 1924). (shrink)

Penrose’s Spin Geometry Theorem is extended further, from SU(2) and E(3) (Euclidean) to E(1, 3) (Poincaré) invariant elementary quantum mechanical systems. The Lorentzian spatial distance between any two non-parallel timelike straight lines of Minkowski space, considered to be the centre-of-mass world lines of E(1, 3)-invariant elementary classical mechanical systems with positive rest mass, is expressed in terms of E(1, 3)-invariant basic observables, viz. the 4-momentum and the angular momentum of the systems. An analogous expression for E(1, 3)-invariant elementary quantum mechanical (...) systems in terms of the basic quantum observables in an abstract, algebraic formulation of quantum mechanics is given, and it is shown that, in the classical limit, it reproduces the Lorentzian spatial distance between the timelike straight lines of Minkowski space with asymptotically vanishing uncertainty. Thus, the metric structure of Minkowski space can be recovered from quantum mechanics in the classical limit using only the observables of abstract quantum mechanical systems. (shrink)

A homeomorphism is built between the separable complex Hilbert space (quantum mechanics) and Minkowski space (special relativity) by meditation of quantum information (i.e. qubit by qubit). That homeomorphism can be interpreted physically as the invariance to a reference frame within a system and its unambiguous counterpart out of the system. The same idea can be applied to Poincaré’s conjecture (proved by G. Perelman) hinting at another way for proving it, more concise and meaningful physically. Furthermore, the conjecture can be generalized (...) and interpreted in relation to the pseudo-Riemannian space of general relativity therefore allowing for both mathematical and philosophical interpretations of the force of gravitation due to the mismatch of choice and ordering and resulting into the “curving of information” (e.g. entanglement). Mathematically, that homeomorphism means the invariance to choice, the axiom of choice, well-ordering, and well-ordering “theorem” (or “principle”) and can be defined generally as “information invariance”. Philosophically, the same homeomorphism implies transcendentalism once the philosophical category of the totality is defined formally. The fundamental concepts of “choice”, “ordering” and “information” unify physics, mathematics, and philosophy and should be related to their shared foundations. (shrink)

In this paper, we introduce the concept of N-dimensional generalized Minkowski space, i.e., a space endowed with a metric tensor, whose coefficients do depend on a set of non-metrical coordinates. This is the first of a series of papers devoted to the investigation of the Killing symmetries of generalized Minkowski spaces. In particular, we discuss here the infinitesimal-algebraic structure of the space-time rotations in such spaces. It is shown that the maximal Killing group of these spaces is the direct product (...) of a generalized Lorentz group and a generalized translation group. We derive the explicit form of the generators of the generalized Lorentz group in the self-representation and their related, generalized Lorentz algebra.

A class of metric theories of gravitation on Minkowski spacetime is considered, which is—provided that certain assumptions (staying close to the original ideas of Einstein) are made—the almost most general one that can be considered. In addition to the Minkowskian metric G a dynamical metric H (called the Einstein metric)is defined by means of a second-rank tensor field S (referred to as gravitational potential).The theory is defined by a Lagrangian ℒ, from which the field equations as well as, e.g., the (...) energy-momentum tensor field for the gravitational field follow. The case of weak fields is considered explicitly. The static, spherically and time-inversal symmetric field is calculated, and as a first step to investigate the theory's viability the parameters are fitted to the experimental data of the perihelion advance and the deflection of light at the Sun. Finally the question of gauge freedoms in the gravitational potential is briefly discussed. (shrink)

Se è nel tempo e attraverso il movimento che partecipiamo alla vita, la morte ci nega per sempre questa possibilità. Nei sistemi viventi il tempo funge da organizzatore della situazione vitale dell’organismo. Il metabolismo e le funzioni vitali si compiono infatti attraverso lo scandire preciso e incalzante di ritmi biologici. Con la morte si verifica il disgregamento della nozione di tempo. Non si tratta più del tempo della vita che unisce, che coordina, che costruisce, che organizza. Il tempo della morte (...) è un tempo che distrugge, che disgrega, che disorienta, che sfilaccia l’unità della nostra esistenza nei frammenti non più ricomponibili di un puzzle. Ma la morte non è un fatto solo individuale, osserva lo psichiatra Eugène Minkowski in Le temps vécu. La morte, infatti, pone anche fine a tutte le relazioni di affetto, parentela e amicizia che ci hanno accompagnato durante la vita. Nell’articolo mostro come, a partire dalla riflessione di Minkowski, si possa parlare della morte da una duplice prospettiva di tempo vissuto: la morte come evento che impone una riflessione sulla finitudine umana, e come esperienza del vissuto individuale, oppure della morte patologica, la quale implica la morte del vissuto, ossia del contatto vitale costitutivo dell`esistenza umana.

The seventeenth century author Nīlakaṇṭha Caturdhara wrote several works criticising the Vedāntic theology of the sixteenth century author, Appayya Dīkṣita. In one of these works, the Vedāntakataka, Nīlakaṇṭha picks out two doctrines for criticism: that the liberated soul becomes the Lord, and that souls thus liberated remain the Lord until all other souls are liberated. These doctrines appear both in Appayya’s Advaitin and in his Śivādvaitin writings. They appear to be ones to which Appayya was committed. They raise theological and (...) conceptual problems, however, both in themselves as doctrines, and as part of nondual Vedāntic teaching. A study of the Vedāntakataka reveals those features of Appayya’s Vedānta that Advaitins in Banaras in the century after his life considered to be anomalous, and illuminates aspects of the context in which his ideas developed and circulated.

Émile Meyerson (1859-1933), philosophe français, juif d'origine polonaise, chimiste formé en Allemagne, a élaboré une œuvre de philosophie des sciences considérable, forte de plusieurs volumes, qui embrasse les conceptions de la science classique comme les principes de la thermodynamique, la théorie de la relativité et la mécanique quantique. L'œuvre de Meyerson a longtemps été négligée dans la tradition épistémologique française, alors qu'elle avait rallié à elle nombre des physiciens aussi éminents qu'Einstein et de Broglie ou des psychiatres comme Minkowski et (...) le jeune Lacan. La " philosophie de l'intellect " de Meyerson fait de la recherche d'invariants dans la nature le principe fondamental de la raison et le ressort inaperçu de l'histoire des sciences. Elle a su aussi bien s'expliquer avec la pensée idéaliste allemande qu'interroger le fonctionnement du sens commun. Elle a entretenu des relations complexes avec certaines théories majeures de son temps, celles de Brunschvicg et de Bachelard, ou celles de Frege et de Schlick. Par son analyse des paradigmes scientifiques du passé, Meyerson annonce Koyré et Kuhn, qui se sont d'ailleurs réclamés de lui. Il ouvre ainsi des perspectives plus que jamais d'actualité dans les débats contemporains en philosophie des sciences. (shrink)

In a doxography of views called the Ṣaṭtantrīsāra, a seventeenth century commentator and Advaitin, Nīlakaṇṭha Caturdhara, describes the doctrines of a group he calls the Miśras. Nīlakaṇṭha represents the doctrines of the Miśras as in most ways distinct from those of the canonical positions that usually appear in such doxographies, both āstika and nāstika. And indeed, some of the doctrines he describes resemble those of the Abrahamic faiths, concerning the creator, a permanent afterlife in heaven or hell, and the unique (...) births of souls. Other doctriness are difficult to associate with any known South Asian religion, for example the emphasis placed on astrological determinism in the moral economy of the creation. As the Ṣaṭtantrīsāra is unpublished to date, a preliminary edition of those portions that concern the Miśras is presented here, together with a translation, notes, and some further discussion. Though the identification is not certain, it seems most likely that the views Nīlakaṇṭha describes in this text belonged to Vanamālī Miśra, a North Indian Mādhva who had lived in the Ganges-Yamuna doab in the mid to late seventeenth century. Even if that identification turns out to be correct, many questions remain. (shrink)

This is one of a group of essays (collected in this issue of the journal) about methodological considerations that have arisen for the project on the “Sanskrit knowledge systems on the eve of colonialism.” For the history of the exact sciences in Sanskrit, or Jyotiḥśāstra, in the early modern period, there are special problems. These have to do with the historically anomalous status of the exact sciences among the śāstras or Sanskrit knowledge systems, and with the predominantly “internalist” method by (...) which most recent research on Jyotiḥśāstra has been carried out. The essay considers the usefulness for tackling these problems of recent writing elsewhere in the history and philosophy of science, especially the work of Hacking. (shrink)

Standard models of adolescent risk taking posit that the cognitive abilities of adolescents and adults are equivalent, and that increases in risk taking that occur during adolescence are the result of socio emotional differences in impulsivity, sensation seeking, and lack of self-control. Fuzzy-trace theory incorporates these socio emotional differences. However, it predicts that there are also cognitive differences between adolescents and adults, specifically that there are developmental increases in gist-based intuition that reflects understanding. Gist understanding, as opposed to verbatim-based analysis, (...) generally has been hypothesized to have a protective effect on risk taking in adolescence. Gist understanding is also an essential element of informed consent regarding risks in medical decision- making. Evidence thus supports the argument that adolescents’ status as mature minors should be treated as an exception rather than a presumption, because accuracy in verbatim analysis is not mature gist understanding. Use of the exception should be accompanied by medical experts’ input on the bottom-line gist of risks involved in treatment. (shrink)

_Seeing the World through Children’s Eyes_ brings an overarching emphasis on ‘seeing’ to early years research and provides an opportunity to see and hear from leading researchers in the field concerning how they work with visual methodologies in their early years research.

Truth depends in some sense on reality. But it is a rather delicate matter to spell this intuition out in a plausible and precise way. According to the theory of truth-making this intuition implies that either every truth or at least every truth of a certain class of truths has a so-called truth-maker, an entity whose existence accounts for truth. This book aims to provide several ways of assessing the correctness of this controversial claim. This book presents a detailed introduction (...) to the theory of truth-making, which outlines truth-maker relations, the ontological category of truth-making entities, and the scope of a truth-maker theory. The essays brought together here represent the most important articles on truth-making in the last three decades as well as new essays by leading researchers in the field of the theory of truth and of truth-making.

A physical mechanical sequence is proposed representing measurement interactions ‘hidden' within QM's proverbial ‘black box'. Our ‘beam splitter' pairs share a polar angle, but head in opposite directions, so ‘led' by opposite hemisphere rotations. For orbital ‘ellipticity', we use the inverse value momentum ‘pairs' of Maxwell's ‘linear' and ‘curl' momenta, seen as vectors on the Poincare spherical surface. Values change inversely from 0 to 1 over 90 degrees, then ± inverts.. Detector polarising screens consist of electrons with the same vector (...) distributions, but polar angles set independently by A & B. The absorption/re-emission interaction process is modelled as surface vector additions at the angle of polar latitude of each interaction. This ‘collapse' of characteristic ‘wave values' is really then simply ‘re-polarisation', with new ellipticity. We then obtain the relation Cosθ at polarisers. We may simplify this to new ellipses with major/minor axis values. Considering as spherical orbital angular momentum rotation we invoke the unique quality of spheres to rotate concurrently on three axes! Rotating on y or z axes concurrent with x axis spin can return surface points to starting positions with non-integer x axis rotations, from half to infinity!. Second interactions at photomultiplier/ analysers are identical but at two orthogonal ‘channels'. Vector addition interactions at BOTH channel orientations normally produce a vector value of adequate amplitude to give a *click* from the MAJOR axis direction. At the ‘crossover' points at near circular polarity the orthogonal ‘certainty' is ~ 50:50, so both or neither channels may produce a ‘click'. The apparently unphysical but proved ‘Malus' law' relation; Cos2θ emerges physically from the 2nd set of interactions. The main departure from QM's assumptions are; That the original pair members each actually possessed two inverse momenta sets; ‘curl' and ‘linear'. Also that complex ‘vector additions' of those pairs occurs. Vector quantities allow A & B to reverse their OWN finding by reversing dial setting, reproducing experimental outputs without problematic ‘non-locality'. (shrink)

A partire da testi profondamente diversi come il Canzoniere petrarchesco e una raccolta di scritti autobiografici di pazienti oncologiche, l'autore compie un'indagine sul concetto di speranza, in particolare sulla sua dimensione temporale e sulla sua connessione con l'attivazione del pensiero. Con riferimenti teorici eterogenei che vanno da Bloch a Borgna, da Minkowski a Marcel, da Demetrio a Bénasayag e Schmit, dalla psicoanalisi alla teologia biblica e alla sociologia, si indagano gli aspetti regressivi e quelli evolutivi della speranza considerata come proiezione (...) del futuro nel presente che influisce sull'elaborzione del proprio passato personale. Infine si osserva come il tempo della contemporaneitÀ sia impermeabile alla speranza, che sopravvive solo in ambiti quali la scrittura, la creativitÀ, la lentezza, il silenzio nei quali ci si puň ancora prendere cura di sé.

The second edition of The Great Psychotherapy Debate has been updated and revised to include a history of healing practices, medicine, and psychotherapy, an expanded theoretical presentation of the contextual model, an examination of therapist effects, and a thorough review of the research on common factors such as the alliance, expectations, and empathy.

The Great Psychotherapy Debate: Models, Methods, and Findings comprehensively reviews the research on psychotherapy to dispute the commonly held view that the benefits of psychotherapy are derived from the specific ingredients contained in a given treatment (medical model). The author reviews the literature related to the absolute efficacy of psychotherapy, the relative efficacy of various treatments, the specificity of ingredients contained in established therapies, effects due to common factors, such as the working alliance, adherence and allegiance to the therapeutic protocol, (...) and effects that are produced by different therapists. In each case, the evidence convincingly corroborates the contextual model and disconfirms the prevailing medical model. (shrink)

'The problem of the twentieth-century is the problem of the color-line.' Originally published in 1903, The Souls of Black Folk is a classic study of race, culture, and education at the turn of the twentieth century. With its singular combination of essays, memoir, and fiction, this book vaulted W. E. B. Du Bois to the forefront of American political commentary and civil rights activism. The Souls of Black Folk is an impassioned, at times searing account of the situation of African (...) Americans in the United States. Du Bois makes a forceful case for the access of African Americans to higher education, memorably extols the achievements of black culture (above all the spirituals or 'sorrow songs'), and advances the provocative and influential argument that due to the inequalities and pressures of the 'race problem', African American identity is characterized by 'double consciousness'. This edition includes a valuable appendix of other writing by Du Bois, which sheds light on his attitudes and intentions. ABOUT THE SERIES: For over 100 years Oxford World's Classics has made available the widest range of literature from around the globe.
