    Acerca de la naturaleza del “yo” narrativo en Dennett.Malena Leon - 2020 - Griot : Revista de Filosofia 20 (2):109-128.
    Dennett elabora una concepción del “yo” entendido como un centro de gravedad narrativo. Uno de los obstáculos principales para valorar esta propuesta radica en que resulta dificultoso entender cuál es la naturaleza del concepto dennettiano de “yo”: concretamente, cuáles son los compromisos ontológicos y epistemológicos que cabe atribuir al fenómeno en cuestión. En este artículo defendemos que el mejor modo de realizar una reconstrucción interpretativa de su noción de “yo” es apelando a la distinción elaborada por Reichenbach entre tres clases (...)

    Hooke's Claim on the Law of Gravity.Nicolae Sfetcu - manuscript
    Based on Galileo's experiments, Newton develops the theory of gravity in his first book Philosophiæ Naturalis Principia Mathematica ("Principia") of 1686. Immediately after, Robert Hooke accused Newton of plagiarism, claiming that he unduly assumed his "notion" of "the rule of the decrease of Gravity, being reciprocally as the squares of the distances from the Center". But, according to Edmond Halley, Hooke agreed that "the demonstration of the curves generated by it" belongs entirely to Newton.

  4. The Trajectory of Self.Timothy Lane, Niall W. Duncan, Tony Cheng & Georg Northoff - 2016 - Trends in Cognitive Sciences 20 (7):481-482.
    In a recent Opinion article, Sui and Humphreys [1] argue that experimental findings suggest self is ‘special’, in that self-reference serves a binding function within human cognitive economy. Contrasting their view with other functionalist positions, chiefly Dennett's [2], they deny that self is a convenient fiction and adduce findings to show that a ‘core self representation’ serves as an ‘integrative glue’ helping to bind distinct types of information as well as distinct stages of psycho- logical processing. In other words, where (...)

    During the period 1870-1914 the existing discipline of psychology was transformed. British thinkers including Spencer, Lewes, and Romanes allied psychology with biology and viewed mind as a function of the organism for adapting to the environment. British and German thinkers called attention to social and cultural factors in the development of individual human minds. In Germany and the United States a tradition of psychology as a laboratory science soon developed, which was called a 'new psychology' by contrast with the old, (...)

Economically developed countries are known as doubtless leaders that are in progress and form political stability, social and economics standards, scientific and technical progress and determine future priorities. It is worth mentioning that the progressive development of national economies in conditions of globalization can take place only in case of the increase of their intellectualization level, through saturation of people`s life, economic relations and production by brain activity, (...)

    The paper seeks to indicate ways in which the crude distinction between Anglo-Saxon and Continental philosophy may have to be amended in light of recent developments in Eastern Europe. As is well known, the philosophy of science is to no small part a product of the universities of the Habsburg Empire (in Vienna, Prague, Lemberg/Lwow, etc.). Logic, too, has played a more significant role in Eastern Europe (not least in Poland) than in the philosophical cultures of Germany or France. For (...)

    This paper explores the possibility of constructing a Cartesian space-time that can resolve the dilemma posed by a famous argument from Newton's early essay, De gravitatione. In particular, Huygens' concept of a center-of-mass reference frame is utilized in an attempt to reconcile Descartes' relationalist theory of space and motion with both the Cartesian analysis of bodily impact and conservation law for quantity of motion. After presenting a modern formulation of a Cartesian space-time employing Huygens' frames, a series of Newtonian (...)

    According to the BSM- Supergravitation Unified Theory (BSM-SG), the energy is indispensable feature of matter, while the matter possesses hierarchical levels of organization from a simple to complex forms, with appearance of fields at some levels. Therefore, the energy also follows these levels. At the fundamental level, where the primary energy source exists, the matter is in its primordial form, where two super-dense fundamental particles (FP) exist in a classical pure empty space (not a physical vacuum). They are associated with (...)

  11. The Unified Equation of Gravity and QM: The Case of Non-Relativistic Motion.Abuzaid Samir - 2014 - AL-Mukhatabat 11.
    We propose to simplify the problem of the unified theory of Quantum-Gravity through dealing first with the simple case of non-relativistic equations of Gravity and Quantum Mechanics. We show that unification of the two non-relativistic formalisms can be achieved through the joined classical and Quantum postulate that every natural body is composed of N identical final particles. This includes the current 'elementary' particles of the standard model such as quarks, photons, gluons, etc. Furthermore, we show that this opens (...)

    Testing the Relativistic Theories of Gravity.Nicolae Sfetcu - manuscript
    In developing general relativity, Einstein was led by theoretical criteria of elegance and simplicity. His theory initially encountered "three classic tests": perihelion precession of Mercury's orbit, deflection of light by the Sun, and gravitational redshift of light. There are large differences in predictions between general relativity and classical physics, such as gravitational time dilation, gravitational lensing, gravitational redshift of light, and so on. And there are many relativistic theories of gravity, bifurcated or independent, but Einstein's general theory of relativity (...)

  13. Quantum Gravity, Timelessness, and the Contents of Thought.David Braddon-Mitchell & Kristie Miller - 2019 - Philosophical Studies 176 (7):1807-1829.
    A number of recent theories of quantum gravity lack a one-dimensional structure of ordered temporal instants. Instead, according to many of these views, our world is either best represented as a single three-dimensional object, or as a configuration space composed of such three-dimensional objects, none of which bear temporal relations to one another. Such theories will be empirically self-refuting unless they can accommodate the existence of conscious beings capable of representation. For if representation itself is impossible in a timeless (...)

    Mathematical Nature of Gravity, Which General Relativity Says is Space-Time : Topology Unites With the Matrix, E=Mc2, Advanced Waves, Wick Rotation, Dark Matter & Higher Dimensions.Rodney Bartlett - manuscript
    General Relativity says gravity is a push caused by space-time's curvature. Combining General Relativity with E=mc2 results in distances being totally deleted from space-time/gravity by future technology, and in expansion or contraction of the universe as a whole being eliminated. The road to these conclusions has branches shining light on supersymmetry and superconductivity. This push of gravitational waves may be directed from intergalactic space towards galaxy centres, helping to hold galaxies together and also creating supermassive black holes. Together (...)

    The current cosmological models are built based on general relativity. The solutions of the specific equations, Friedmann-Lemaître-Robertson-Walker, allow to model the evolution of the universe starting from the Big Bang. Some of the parameters of the universe have been established by observations. Based on these, and other observational data, the models can be tested. Predictions include the initial abundance of chemical elements formed in a period of nucleosynthesis during the Big Bang period, the subsequent structure of the universe, cosmic background (...)

    What it would take to vindicate folk temporal error theory? This question is significant against a backdrop of new views in quantum gravity—so-called timeless physical theories—that claim to eliminate time by eliminating a one-dimensional substructure of ordered temporal instants. Ought we to conclude that if these views are correct, nothing satisfies the folk concept of time and hence that folk temporal error theory is true? In light of evidence we gathered, we argue that physical theories that entirely eliminate an (...)

    Laboratory Test of a Class of Gravity Models.Richard Benish - 2007 - Apeiron 14 (4):362.
    Ideas for explaining the mechanism of gravity involving the expansion of matter have been proposed several times since the 1890’s. Due to their radical nature and other reasons, these ideas have not gotten much attention. Another essential feature needed to augment the viability of the model proposed here---even more important than matter expansion---is that of space generation. I.e., the production of space by matter, involving motion into or outfrom a fourth spatial dimension. An experiment is proposed whose result would (...)

    Life is the center of our existence. One would be tempted to say that first of all we live. However, our existence does not seem to pass in that modality. The exacerbated materialism in which our existence takes place, displaces life from the center of the scene. Our society is organized around production, consumerism, exploitation, efficiency, trade and propaganda. That is to say, our existence seems to have economy as the center of organization of our activities. The (...)

Lee and Kip S. Thorne (“The Foundation of Theory of Gravitational Theories”. Phys. Rev. D 1973, vol.7, pp.3563-3572) can help to solve the theory –choice problem in principle.

  23. To the Center of the Sky: Heidegger, Polar Symbolism, and Christian Sacred Architecture.William Behun - 2009 - Environment, Space, Place 1 (1):7-25.
    Heidegger’s sense of the holy is an important aspect of his thought, especially in the form that it takes in his later work. By juxtaposingHeidegger’s thinking on the sacred with traditional metaphysician René Guénon’s examination of the symbolism of the sacred pole, we can bring both elements into clearer focus. This paper undertakes to draw together these two radically disparate thinkers not to undermine either’s project, but rather to demonstrate one way in which the sacred can be more thoroughly understood, (...)

  25. Spacetime Emergence in Quantum Gravity: Functionalism and the Hard Problem.Baptiste Le Bihan - 2019 - Synthese.
    Spacetime functionalism is the view that spacetime is a functional structure implemented by a more fundamental ontology. Lam and Wüthrich have recently argued that spacetime functionalism helps to solve the epistemological problem of empirical coherence in quantum gravity and suggested that it also (dis)solves the hard problem of spacetime, namely the problem of offering a picture consistent with the emergence of spacetime from a non-spatio-temporal structure. First, I will deny that spacetime functionalism solves the hard problem by showing that (...)

    Principles are central to physical reasoning, particularly in the search for a theory of quantum gravity (QG), where novel empirical data is lacking. One principle widely adopted in the search for QG is UV completion: the idea that a theory should (formally) hold up to all possible high energies. We argue---/contra/ standard scientific practice---that UV-completion is poorly-motivated as a guiding principle in theory-construction, and cannot be used as a criterion of theory-justification in the search for QG.

This conflict is supposed to be solved only by unifying gravity with the other three interactions, to integrate GR and QFT into one theory. At the (...)

    Quantum gravity has required the consideration of fundamental epistemological questions, which can be identified in philosophy with the mind-body problem and the problem of free will. These questions influenced the epistemology of quantum mechanics in the form of von Neumann's "psycho-physical parallelism" and the subsequent analysis of the thesis by Wigner that "the collapse of the wave packet" occurs in the mind of the "observer".

    The classic example of a successful research program is Newton's gravitational theory, probably the most successful Lakatosian research program. Initially, Newton's gravitational theory faced a lot of "anomalies" ("counterexamples") and contradicted the observational theories that supported these anomalies. But supporters of the Newtonian gravity research program have turned every anomaly into corroborating cases. Moreover, they themselves pointed to counterexamples which they then explained through Newtonian theory . DOI: 10.13140/RG.2.2.32489.85601.

    Important features of space and time are taken to be missing in quantum gravity, allegedly requiring an explanation of the emergence of spacetime from non-spatio-temporal theories. In this paper, we argue that the explanatory gap between general relativity and non-spatio- temporal quantum gravity theories might significantly be reduced with two moves. First, we point out that spacetime is already partially missing in the context of general relativity when understood from a dynamical perspective. Second, we argue that most approaches (...)

    Epistemology of Canonical Quantum Gravity - Loop Quantum Gravity.Nicolae Sfetcu - manuscript
    In the interpretation of canonical quantum gravity (CQG), gravity appears as a geometric pseudoforce, is reduced to spacetime geometry and becomes a simple effect of spacetime curvature. The scale at which quantum gravitational effects occur is determined by the different physical constants of fundamental physics: h, c and G, which characterize quantum, relativistic and gravitational phenomena. By combining these constants, we obtain the Planck constants at which the effects of quantum gravity must manifest. Loop quantum gravity (...)

  43. In General Relativity, Gravity is Effect of Coordinates with Change of Geometry of Spacetime.Alfonso Leon Guillen Gomez - manuscript
    Einstein structured the theoretical frame of his work on gravity under the Special Relativity and Minkowski´s spacetime using three guide principles: The strong principle of equivalence establishes that acceleration and gravity are equivalents. Mach´s principle explains the inertia of the bodies and particles as completely determined by the total mass existent in the universe. And, general covariance searches to extend the principle of relativity from inertial motion to accelerated motion. Mach´s principle was abandoned quickly, general covariance resulted mathematical (...)

  44. The Use (and Misuse) of 'Cognitive Enhancers' by Students at an Academic Health Sciences Center.J. Bossaer, J. A. Gray, S. E. Miller, V. C. Gaddipati, R. E. Enck & G. G. Enck - 2013 - Academic Medicine (7):967-971.
    Purpose Prescription stimulant use as “cognitive enhancers” has been described among undergraduate college students. However, the use of prescription stimulants among future health care professionals is not well characterized. This study was designed to determine the prevalence of prescription stimulant misuse among students at an academic health sciences center. -/- Method Electronic surveys were e-mailed to 621 medical, pharmacy, and respiratory therapy students at East Tennessee State University for four consecutive weeks in fall 2011. Completing the survey was voluntary (...)

    Epistemology of String Theory in Quantum Gravity.Nicolae Sfetcu - manuscript
    In quantum field theory, the main obstacle is the occurrence of the untreatable infinities in the interactions of the particles due to the possibility of arbitrary distances between the point particles. Strings, as extended objects, provide a better framework, which allows finite calculations. String theory is part of a research program in which point particles in particle physics are replaced by one-dimensional objects called strings. It describes how these strings propagate through space and interact with one another. The purpose of (...)

    Understanding of Authorship by the Post Graduate Medical Students at a Center in Bangladesh.S. P. Lasker - 2021 - Bangladesh Journal of Bioethics 12 (1):25-34.
    Education on authorship was delivered and evaluated by pre test and post test questionnairen on 30 post graduate medical students at the Department of Anestheology, Dhaka Medical College, Bangladesh between January and June 2019 to understand the knowledge, skill and attitude of post graduate medical students on authorship. Result: Before intervention, majority (60%) of the students felt that who perform the research work should be the author of the article. But 40% students were divided and felt that who advised the (...)

  47. Presentism and Quantum Gravity.Bradley Monton - 2001 - In Dennis Dieks (ed.), The Ontology of Spacetime.
    There is a philosophical tradition of arguing against presentism, the thesis that only presently existing things exist, on the basis of its incompatibility with fundamental physics. I grant that presentism is incompatible with special and general relativity, but argue that presentism is not incompatible with quantum gravity, because there are some theories of quantum gravity that utilize a fixed foliation of spacetime. I reply to various objections to this defense of presentism, and point out a flaw in Gödel's (...)

    Epistemology of Newtonian Gravity.Nicolae Sfetcu - manuscript
    The first edition of Newton's Principia contains only two additional comments on the methodology: the notification that the purpose of the paper is to explain "how to determine the true motions from their causes, effects, and apparent differences, and, conversely, how to determine from motions, whether true or apparent, their causes and effects"; and, in the Scholium at the end of Book 1, Section 11, Newton asserts that his distinctive approach makes possible a safer argumentation in natural philosophy.

    Quantum Gravity As the Unification of General Relativity & Quantum Mechanics.Vasil Penchev - 2020 - Philosophy of Science eJournal (Elsevier: SSRN) 13 (32):1-3.
    A nonstandard viewpoint to quantum gravity is discussed. General relativity and quantum mechanics are to be related as two descriptions of the same, e.g. as Heisenberg’s matrix mechanics and Schrödinger’s wave mechanics merged in the contemporary quantum mechanics. From the viewpoint of general relativity one can search for that generalization of relativity implying the in-variance “within – out of” of the same system.

  50. Inter-Theory Relations in Quantum Gravity: Correspondence, Reduction and Emergence.Karen Crowther - 2018 - Studies in History and Philosophy of Modern Physics 63:74-85.
    Relationships between current theories, and relationships between current theories and the sought theory of quantum gravity (QG), play an essential role in motivating the need for QG, aiding the search for QG, and defining what would count as QG. Correspondence is the broad class of inter-theory relationships intended to demonstrate the necessary compatibility of two theories whose domains of validity overlap, in the overlap regions. The variety of roles that correspondence plays in the search for QG are illustrated, using (...)
