In the present paper I argue that the formalism of Newtonian mechanics stems directly from the general principle to be called the principle of microlevel reducibility which physical systems obey in the realm of classical physics. This principle assumes, first, that all the properties of physical systems must be determined by their states at the current moment of time, in a slogan form it is ``only the present matters to physics.'' Second, it postulates that any physical system is nothing but (...) an ensemble of structureless particles arranged in some whose interaction obeys the superposition principle. I substantiate this statement and demonstrate directly how the formalism of differential equations, the notion of forces in Newtonian mechanics, the concept of phase space and initial conditions, the principle of least actions, etc. result from the principle of microlevel reducibility. The philosophical concept of thick presentism and the introduction of two dimensional time-physical time and meta-time that are mutually independent on infinitesimal scales-are the the pivot points in these constructions.

The derivative is a basic concept of differential calculus. However, if we calculate the derivative as change in distance over change in time, the result at any instant is 0/0, which seems meaningless. Hence, Newton and Leibniz used the limit to determine the derivative. Their method is valid in practice, but it is not easy to intuitively accept. Thus, this article describes the novel method of differential calculus based on the double contradiction, which is easier to accept intuitively. Next, (...) the geometrical meaning of the double contradiction is considered as follows. A tangent at a point on a convex curve is iterated. Then, the slope of the tangent at the point is sandwiched by two kinds of lines. The first kind of line crosses the curve at the original point and a point to the right of it. The second kind of line crosses the curve at the original point and a point to the left of it. Then, the double contradiction can be applied, and the slope of the tangent is determined as a single value. Finally, the meaning of this method for the foundation of mathematics is considered. We reflect on Dehaene’s notion that the foundation of mathematics is based on the intuitions, which evolve independently. Hence, there may be gaps between intuitions. In fact, the Ancient Greeks identified inconsistency between arithmetic and geometry. However, Eudoxus developed the theory of proportion, which is equivalent to the Dedekind Cut. This allows the iteration of an irrational number by rational numbers as precisely as desired. Simultaneously, we can define the irrational number by the double contradiction, although its existence is not guaranteed. Further, an area of a curved figure is iterated and defined by rectilinear figures using the double contradiction. (shrink)

Plato's view on time, a key aspect of his doctrine of forms, is influenced by his reception of Parmenides, but the way in which Plato takes up and modifies Parmenides' view is a matter of ongoing scholarly debate. In this article, the author analyzes Plato's revision of Parmenidean time by exploring four temporalities: the eternal present, timeless eternity, the enduring present, and the instant between time and eternity. Through this examination, she uncovers the common origin of both the eternal (...) present of Parmenides' fragment B8 and the flowing present of the phenomenal realm in the instant (ἐξαίφνης) in Plato's Parmenides. This perspective on time offers a promising solution to Plato's problem of participation, bridging the gap between the eternal being of the form and the being in time of the particulars. (shrink)

El artículo aborda el problema del instante (Augenblick) a partir de la obra temprana de Martin Heidegger y su prolongación en Ser y tiempo. La persuasión de que solo el cristianismo primitivo ha vivido una temporalidad originaria, se prolonga en Ser y tiempo en una interpretación del instante como integración del pasado y del futuro. Aquello que en Aristóteles no alcanzaba a constituirse –la conexión entre kairós y výn– encuentra su pleno develamiento en la escatología paulina. Sin embargo, el ésjaton (...) de la parusía cristiana se convierte en Ser y tiempo en una escatología de la muerte. (shrink)

Many philosophers hold that ‘one-instant worlds’—worlds that contain a single instant—fail to contain time. We experimentally investigate whether these worlds satisfy the folk concept of time. We found that ~50% of participants hold that there is time in such worlds. We argue that this suggests one of two possibilities. First, the population disagree about whether at least one of the A-, B-, or C-series is necessary for time, with there being a substantial sub-population for whom the presence of (...) neither an A-, B-, nor C-series, is necessary for time, and hence those folk have a radically more minimal concept of time than has been attributed to them by philosophers. Or, second, the population do not disagree about whether at least one of the A-, B-, or C-series is necessary for time, but disagree about what it takes for a world to fail to contain even a C-series.

O presente artigo ambiciona discutir dois conceitos importantes presentes na última fase da filosofia poética de Gaston Bachelard, onde o pensador adotou o método fenomenológico das imagens poéticas, são eles: solidão e instante vertical. Logo em seguida, demonstraremos de que modo esses dois conceitos que são, diga-se de passagem, um tanto quanto curiosos, se conectam e, em certa medida, autorizam o pensador a definir precisamente o que é essa poesia produzida pelo artista, bem como, o impacto de uma obra poética (...) na vida daqueles leitores que intimamente foram sensibilizados pelo acontecimento criador e revelador de mundos que é a poesia.

Extending on an earlier paper [Found. Phys. Ltt., 16(4) 343–355, (2003)], it is argued that instants of time and the instantaneous (including instantaneous relative position) do not actually exist. This conclusion, one which is also argued to represent the correct solution to Zeno’s motion paradoxes, has several implications for modern physics and for our philosophical view of time, including that time and space cannot be quantized; that contrary to common interpretation, motion and change are compatible with the “block” universe and (...) relativity; and that time, space, and space-time too, cannot exist. Instead, motion and change become the major players. (shrink)

Korea Atomic Energy Research Institute (KAERI) has been carrying out a scaled-down moderator test program to simulate the CANDU-6 moderator circulation phenomena during steady state operation and accident conditions. The Moderator Circulation Test (MCT) facility was designed and constructed as 1/4 scale of the prototype of CANDU-6 reactor. In the present work spatial distribution of two-dimensional velocity in the MCT facility under isothermal condition was measured using planar Particle Image Velocimetry (PIV) system which consists of double pulsed laser, synchronizer, (...) and high speed camera. TSI’s Insight TM 4G software was used to perform PIV image capturing, PIV calculation and post processing. 10 μm sized silver-coated hollow sphere particles were used as flow tracer particles. Multiple experiments were conducted to cover large area of the MCT facility with limited field of view of a single camera. Instantaneous and averaged velocity field were analyzed for each spatial position and flow rate. This research is capable of offering validation data for self-reliant CFD tools to predict moderator subcooling margin in CANDU-6 reactor. (shrink)

The flame displacement speed is one of the major characteristics in turbulent premixed flames. The flame displacement speed is experimentally obtained from the displacement normal to the flame surface, while it is numerically evaluated by the transport equation of the flame surface. The flame displacement speeds obtained both experimentally and numerically cannot be compared directly because their definitions are different. In this study, two kinds of experimental flame displacement speeds—involving the mean inflow velocity and the local flow velocity—were (...) simulated using the DNS data with the different Lewis numbers, and were compared with the numerical flame displacement speed. The simulated experimental flame displacement speed involving the mean inflow velocity had no correlation with the numerical flame displacement speed, while the simulated displacement speed involving the local flow velocity had a clear correlation with the numerical displacement speed in the cases of higher Lewis number than unity. The correlation coefficient of the simulated displacement speed involving the local flow velocity with the numerical displacement speed had a maximum value on the isosurface of the reaction progress variable with the maximum temperature gradient where the dilation effect of the flame is strongest.

The local burning velocity and the flame displacement speed are the dominant properties in the mechanism of turbulent premixed combustion. The flame displacement speed and the local burning velocity have been investigated separately, because the flame displacement speed can be used for the discussion of flame-turbulence interactions and the local burning velocity can be used for the discussion of the inner structure of turbulent premixed flames. In this study, to establish the basis for the discussion on the (...) effects of turbulence on the inner structure of turbulent premixed flames, the indirect relationship between the flame displacement speed and the local burning velocity was investigated by the flame stretch, the flame curvature, and the tangential strain rate using DNS database with different density ratios. It was found that for the local tangential strain rate and the local flame curvature, the local burning velocity and the flame displacement speed had the opposite correlations in each density ratio case. Therefore, it is considered that the local burning velocity and the flame displacement speed have a negative correlation. (shrink)

The study developed and determined instant melon (Citrulluscolocynthis) soup powder’s shelf life for working-class mothers in Lagos, Nigeria. The study adopted research and development design. The population for the study was 2,077. The sample size for the study was 341. This consisted of three groups made up of 25 lecturers, 192 mothers working in banks and 124 mothers working. Seven sets of instruments were used for data collection. Data was analyzed using mean and standard deviation for the research questions. (...) Findings of the study indicated that the shelf life determinants included free fatty acid (FFA), moisture content and total viable count measured over a period of 22 weeks. From the analysis, FFA content slightly appreciated over the weeks; from 0.60 at the start to 0.7 5 at 4weeks; 0.86 at 8weeks; 0.95 at 12 weeks; 1.70 at 16 weeks and 4.06 at 22 weeks. The analysis showed that the moisture content of the developed melon soup powder slightly decreased over the weeks; from 9.41 at the start to 9.30 at 4 weeks; 9.00 at 8 weeks; 8.82 at 12 weeks; 8.60 at 16 weeks and 8.30 at 22 weeks. The total viable count (TVC) of the developed melon soup powder increased over the weeks. At the start of the experiment, the TVC of the developed melon soup powder was 8; TVC increased to 10 at 4 weeks; 14 at 8 weeks; 15 at 12 weeks; 18 at 16 weeks and 29 at 22 weeks. (shrink)

This paper presents an investigation about the instant in Heidegger, articulating the analytics of Dasein by Being and Time with the thought of Ereignis. Therefore, it seeks to think, as a presupposition, the existence in his character of temporality. The human being is conceived as Dasein, i. e, in its fundamental relationship to the Being as such. The essence of Dasein is existence. The existence is grounded on Sorge (concern, care), which, in turn, is grounded on temporality. The most (...) own temporality brings together future, past and present in the dynamics of an anticipatory decision on which the man, accepting himself as being-unto-death, it becomes free for their power-to-be authentic, in a response of dedication and self-donation to the call of Being. This gather together future, past and present in the authentic existence, i.e, in the most own temporality: the instant. Keywords: existence; resolution; temporality; instant; man; Being. (shrink)

The photon is typically regarded as a unitary object that is both particle-discrete and wave-continuous. This is a paradoxical position and we live with it by making dualism a fundamental feature of radiation. It is argued here that the photon is not unitary; rather it has two identities, one supporting discrete behavior and the other supporting continuous (wave) behavior. There is photon kinetic energy that is always discrete/localized on arrival; it never splits (on half-silvered mirrors) or diffracts (in pinholes or (...) slits). Then there is the photon’s probability wavefront that is continuous and diffractable. Acknowledging that the photon has two identities explains the photon’s dual nature. And wave-particle duality is central to quantum mechanics. Understanding it leads to new insights into the photon’s constant velocity and its entanglement with another photon. (shrink)

The impetus theory of motion states that to be in motion is to have a non-zero velocity. The at-at theory of motion states that to be in motion is to be at different places at different times, which in classical physics is naturally understood as the reduction of velocities to position developments. I first defend the at-at theory against the criticism raised by Arntzenius that it renders determinism impossible. I then develop a novel impetus theory of motion that reduces (...) positions to velocity developments. As this impetus theory of motion is by construction a mirror image of the at-at theory of motion, I claim that the two theories of motion are in fact epistemically on par—despite the unfamiliar metaphysical picture of the world furnished by the impetus version.

The paper will study an unpublished 1930–31 seminar where Heidegger reads Plato’s Parmenides, showing that in spite of his much-criticized habit of dismissing Plato as the progenitor of “idealist” metaphysics, Heidegger was quite aware of the radical potential of his later dialogues. Through a temporal account of the notion of oneness (to hen), the Parmenides attempts to reconcile the plurality of beings with the unity of Being. In Heidegger’s reading, the dialogue culminates in the notion of the “instant” (to (...) exaiphnēs, Augenblick)—a high point in the entire metaphysical tradition—where the temporal plurality of presence and un-presence converges into a unified disclosure.

Most of our best scientific descriptions of the world employ rates of change of some continuous quantity with respect to some other continuous quantity. For instance, in classical physics we arrive at a particle’s velocity by taking the time-derivative of its position, and we arrive at a particle’s acceleration by taking the time-derivative of its velocity. Because rates of change are defined in terms of other continuous quantities, most think that facts about some rate of change obtain in (...) virtue of facts about those other continuous quantities. For example, on this view facts about a particle’s velocity at a time obtain in virtue of facts about how that particle’s position is changing at that time. In this paper we raise a puzzle for this orthodox reductionist account of rate of change quantities and evaluate some possible replies. We don’t decisively come down in favour of one reply over the others, though we say some things to support taking our puzzle to cast doubt on the standard view that spacetime is continuous. (shrink)

Nosso objetivo é mostrar como Bachelard edifica a noção de vida em sua filosofia ao esboçar uma reflexão sobre o problema filosófico do tempo junto às noções de instante e duração. O livro A intuição do instante (1932), obra dedicada a esta reflexão metafísica sobre o tempo confluindo, quatro anos mais tarde, para A dialética da duração (1936), obra que, por sua vez, define o conceito de duração a partir das várias temporalidades superpostas constitutivas da própria existência, são as referências (...) privilegiadas deste estudo. Ressaltaremos a importância da filosofia de Henri Bergson nesta discussão ao estabelecermos um contraponto entre suas teses sobre a vida e a duração às mesmas teses conceituais bachelardianas, sobretudo a partir da oposição entre as seguintes noções: vida vivida (circunscrita ao tempo comum/tempo transitivo em Bergson) e vida pensada (circunscrita ao tempo do espírito/tempo imanente em Bachelard). Partimos da hipótese a ser debatida de que é porque o espírito pode chocar-se com a vida vulgar, escorregadia e homogênea que a vida superior, ou seja, do próprio espírito, deve ser entendida nesta filosofia bachelardiana como sendo uma construção racional ancorada em uma dialética pluralista de saberes sobre o tempo.

Some Presentists—according to whom everything is present—identify instants of time with propositions of a certain kind. However, the view that times are propositions seems to be at odds with Presentism: if there are times then there are past times, and therefore things that are past; but how could there be things that are past if everything is present? In this paper, we describe the Presentist view that times are propositions ; we set out the argument that Presentism is incompatible with (...) the view that times are propositions ; and then we describe three possible responses to that argument on behalf of Presentists who identify times with propositions. We argue that each of these responses comes with significant costs. Finally, we describe a fourth possible response—according to which times are irreducibly higher-order entities—which appears to avoid the costs of the other three. We also describe and respond to two objections to the higher-order strategy. (shrink)

The electronic and muonic hydrogen energy levels are calculated very accurately [1] in Quantum Electrodynamics (QED) by coupling the Dirac Equation four vector (c ,mc2) current covariantly with the external electromagnetic (EM) field four vector in QED’s Interactive Representation (IR). The c -Non Exclusion Principle(c -NEP) states that, if one accepts c as the electron/muon velocity operator because of the very accurate hydrogen energy levels calculated, the one must also accept the resulting electron/muon internal spatial and time coordinate operators (...) (ISaTCO) derived directly from c without any assumptions. This paper does not change any of the accurate QED calculations of hydrogen’s energy levels, given the simplistic model of the proton used in these calculations [1]. The Proton Radius Puzzle [2, 3] may indicate that new physics is necessary beyond the Standard Model (SM), and this paper describes the bizarre, and very different, situation when the electron and muon are located “inside” the spatially extended proton with their Centers of Charge (CoCs) orbiting the proton at the speed of light in S energy states. The electron/muon center of charge (CoC) is a structureless point that vibrates rapidly in its inseparable, non-random vacuum whose geometry and time structure are defined by the electron/muon ISaTCO discrete geometry. The electron/muon self mass becomes finite in a natural way due to the ISaTCOs cutting off high virtual photon energies in the photon propagator. The Dirac-Maxwell-Wilson (DMW) Equations are derived from the ISaTCO for the EM fields of an electron/muon, and the electron/muon “look” like point particles in far field scattering experiments in the same way the electric field from a sphere with evenly distributed charge “e” “looks” like a point with the same charge in the far field (Gauss Law). The electron’s/muon’s three fluctuating CoC internal spatial coordinate operators have eight possible eigenvalues [4, 5, 6] that fall on a spherical shell centered on the electron’s CoM with radius in the rest frame. The electron/muon internal time operator is discrete, describes the rapid virtual electron/positron pair production and annihilation. The ISaTCO together create a current that produce spin and magnetic moment operators, and the electron and muon no longer have “intrinsic” properties since the ISaTCO kinematics define spin and magnetic moment properties.

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 unequivocally (...) either falsify the model or support it. Analyses of star cluster velocity dispersions suggest that some support already exists. The simplest, most definitive way to test the model is to build and operate an apparatus that may be called a Small Low-Energy Non-Collider. Essentially the same experiment was proposed by Galileo in 1632. We are way overdue to at last bring to fruition this idea put forth by the Father of Modern Science so long ago. (shrink)

O objetivo da presente dissertação é mostrar como Bachelard edifica a noção de vida em sua filosofia por meio de uma reflexão sobre o problema filosófico do tempo e das noções de instante e duração. Ao refletirmos sobre o instante descontínuo associando-o a outros conceitos que perpassam seus escritos, tanto epistemológicos, quanto poéticos, estabeleceremos de que maneira o pressuposto teórico de complementariedade entre as duas vertentes de seu pensamento é alcançado. Destacaremos também que em sua metafísica o ser do homem (...) busca sua referência autosincrônica por meio da experiência descontínua do instante verdadeiramente dinâmico, onde o tempo não corre, jorra. O livro A intuição do instante (1932), obra dedicada a esta reflexão metafísica sobre o tempo conflui, quatro anos mais tarde, para A dialética da duração (1936), obra que, por sua vez, define o conceito de duração a partir das várias temporalidades superpostas constitutivas da própria existência, ambas apresentam os fundamentos de uma filosofia do repouso e são as referências privilegiadas deste estudo. Não é necessário ressaltar a importância da filosofia de Henri Bergson nesta discussão: é a partir de um contraponto com suas teses, tanto sobre a vida como sobre a duração, que Bachelard irá forjar sua própria compreensão do conceito de vida por meio de uma oposição que é sublinhada ao longo de suas duas obras temporais, ou seja, entre vida vivida (circunscrita ao tempo comum/tempo transitivo) e vida pensada (circunscrita ao tempo do espírito/tempo imanente). Partimos da hipótese de que é porque o espírito pode chocar-se com a vida vulgar, escorregadia e homogênea que a vida superior, ou seja, do próprio espírito, deve ser entendida nesta filosofia como sendo uma construção racional apoiada em uma dialética pluralista de saberes sobre o tempo. No final deste trabalho tentaremos esboçar alguns apontamentos relativos à valorização da vida pelo pensamento bachelardiano que a torna ritmicamente variada e harmônica. (shrink)

In a preceding publication a fundamentally oriented and irreversible world was shown to be de- rivable from the important principle of least action. A consequence of such a paradigm change is avoidance of paradoxes within a “dynamic” quantum physics. This becomes essentially possible because fundamental irreversibility allows consideration of the “entropy” concept in elementary processes. For this reason, and for a compensation of entropy in the spread out energy of the wave, the duality of particle and wave has to be (...) mediated via an information self-image of matter. In this publication considerations are extended to irreversible thermodynamics, to gravitation and cos- mology with its dependence on quantum interpretations. The information self-image of matter around particles could be identified with gravitation. Because information can also impose an al- ways constant light velocity there is no need any more to attribute such a property to empty space, as done in relativity theory. In addition, the possibility is recognized to consider entropy genera- tion by expanding photon fields in the universe. Via a continuous activation of information on matter photons can generate entropy and release small energy packages without interacting with matter. This facilitates a new interpretation of galactic redshift, emphasizes an information link between quantum- and cosmological phenomena, and evidences an information-triggered origin of the universe. Self-organized processes approach maximum entropy production within their constraints. In a far from equilibrium world also information, with its energy content, can self- organize to a higher hierarchy of computation. It is here identified with consciousness. This ap- pears to explain evolution of spirit and intelligence on a materialistic basis. Also gravitation, here identified as information on matter, could, under special conditions, self-organize to act as a su- per-gravitation, offering an alternative to dark matter. Time is not an illusion, but has to be understood as flux of action, which is the ultimate reality of change. The concept of an irreversible physical world opens a route towards a rational understanding of complex contexts in nature. (shrink)

This article shows how the so-called digital ontology betrays the metaphysical-theological thought of Leibniz (of which it claims to be heir), giving rise to an apparent “algorithmic providence” which, however, confines subjects in algorithmic types, making it impossible the occurrence of event and of the new. If digital ontology sees in Leibniz a thinker from whom to interpret being on the basis of algorithms, this article – by reconstructing Leibniz’s thought – wants to show not only how the operation of (...) digital ontology is not legitimate, but also how – through Leibniz’s doctrine of the divine decrees – it is possible to think of a praxis effectively generating of event. Starting from Leibniz, therefore, we will describe a metaphysics of the instant, in which the moment of decision and action is untied from algorithmic determinism. In conclusion, the article proposes that the theological-metaphysical notion of Providence can constitute a central idea for thinking a practice that is able to transcend the immanence of virtual reality, dominated by algorithmic determinism and the indefinite reproduction of the identical.

The main purpose of the thesis is to identify and fill some gaps that are regularly found in the analysis of the Platonic concept of ἐξαίφνης. The word ἐξαίφνης, which appears 36 times in the Platonic dialogues, has primarily been examined and discussed in relation to what is said in Parmenides and, more rarely, in Symposium, Republic and Seventh Letter. However, as is known, the word is also found in Gorgias, Cratylus, Theaetetus, Statesman and Laws. Moreover, it is worth noting (...) that a history of criticism about the concept of ἐξαίφνης has never been provided, mainly due to the chronological and interpretive difficulties relating to Parmenides. This absence brought on a fragmentation and discontinuity in the study of the concept and it often prompted specialists to see in this notion a secondary or imprecise aspect of the Platonic theory. Regardless of the correctness of interpretations that have been proposed over the centuries, my work clearly shows that all these exegeses share two fundamental limits: the former is a necessarily partial analysis, almost exclusively based on what is written in Parmenides, the latter is the absence of a historical perspective . Cette thèse portant sur le concept d’ἐξαίφνης tel qu’on le trouve dans les textes de Platon se propose de combler les lacunes existantes relatives à l’analyse de ce concept. En effet, le terme d’ἐξαίφνης, dont on trouve trente-six occurrences dans les dialogues de Platon n’a été jusqu’à présent principalement envisagé et examiné qu’à travers ce qui en est dit dans le Parménide et, plus rarement, dans le Banquet, la République et la Lettre VII. Le terme, comme on le sait, se trouve pourtant aussi dans le Gorgias, le Cratyle, le Théétète, le Politique et les Lois. En outre, en raison notamment des difficultés chronologiques et interprétatives liées au dialogue du Parménide, aucune histoire critique du concept d’ἐξαίφνης n’a été entreprise. Cette absence d’histoire critique a pour effet une fragmentation et une discontinuité des études portant sur ce concept, effets qui ont souvent conduit les spécialistes à ne voir dans cette notion qu’un aspect secondaire ou à tout le moins imprécis de la théorie que développe Platon à son sujet. Aussi la thèse s’est-elle attachée à entreprendre une étude préalable de l’histoire de ces interprétations. Quelle que soit la justesse et la valeur des interprétations qui se sont succédées au cours des siècles, cette étude s’emploie à montrer clairement que ces tendances exégétiques se heurtent à deux limites fondamentales que la thèse s’applique à lever : la première est le caractère nécessairement partiel d’une analyse menée presque exclusivement à partir du Parménide, la seconde est l’absence de mise en perspective historique.

There is a widespread assumption that B-theorists (according to whom there is nothing metaphysically special about the present moment in virtue of which it is present) should interpret the standard tense operators (‘it was the case that’, ‘it will be the case that’) as implicit quantifier-restrictors – so that, for example, an utterance at instant t of the sentence ‘It was the case that there are dinosaurs’ is true just in case there are dinosaurs located at some instant (...) t* earlier than t. However, it is easy to show that this interpretation of the tense operators creates serious problems for B-theorists when combined with certain other relatively uncontroversial B-theoretic assumptions. In this paper, I argue that the best way for B-theorists to respond to these problems is to treat the standard tense operators as redundant when the sentences in their scope are qualitative (i.e. not about any particular individuals).

By a `denoting phrase' I mean a phrase such as any one of the following: a man, some man, any man, every man, all men, the present King of England, the present King of France, the center of mass of the solar system at the first instant of the twentieth century, the revolution of the earth round the sun, the revolution of the sun round the earth. Thus a phrase is denoting solely in virtue of its form. We may (...) distinguish three cases: (1) A phrase may be denoting, and yet not denote anything; e.g., `the present King of France'. (2) A phrase may denote one definite object; e.g., `the present King of England' denotes a certain man. (3) A phrase may denote ambiguously; e.g. `a man' denotes not many men, but an ambiguous man. The interpretation of such phrases is a matter of considerably difficulty; indeed, it is very hard to frame any theory not susceptible of formal refutation. All the difficulties with which I am acquainted are met, so far as I can discover, by the theory which I am about to explain. (shrink)

Attraverso una breve e veloce premessa storico-critica e storico-filosofica il testo proposto fa emergere il tema del rapporto problematico sussistente fra l'attuale ideologia che sorregge il fenomeno economico, sociale e politico della globalizzazione internazionale dei capitali (soprattutto finanziari) ed i riflessi di ordine umano e naturale che ne sono l'effettiva conseguenza. Da un punto di vista psicologico, sociale ed educativo l'impianto ideologico neoliberista viene allora contrastato dalla ripresa di un pensiero critico, radicale e rivoluzionario, che riutilizza il principio dell'infinito creativo (...) e doppiamente dialettico, di lontana matrice presocratica e bruniana. Il testo analizza la progressione di avvicinamento a tale principio preparata dalle riflessioni di H. Marcuse, W. Reich, G. Deleuze, C. Castoriadis e A. Badiou. (shrink)

Positions taken in the current debate over free will can be seen as responses to the following conditional: -/- If every action is caused solely by another event and a cause necessitates its effect, then there is no action to which there is an alternative (C). -/- The Libertarian, who believes that alternatives are a requirement of free will, responds by denying the right conjunct of C’s antecedent, maintaining that some actions are caused, either mediately or immediately, by events whose (...) effects could be different, even if they were to recur under identical circumstances. We have here a denial of Laplacian Determinism (LD), according to which the condition of the world at any instant makes only one state possible at any other instant. One prominent defender of this view, Robert Kane, holds that unless an agent’s neural mechanisms operated indeterministicly in forming her character she is not responsible for its manifestations. This requirement is entailed by the principle of “ultimate responsibility” (UR) according to which an act is freely willed only if (a) its agent is personally responsible for its performance in the sense of having caused it to occur by voluntarily doing something that was avoidable and (b) there is no sufficient condition for its performance for which its agent is not personally responsible. The orthodox Compatibilist, adducing counterexamples to UR, argues that even if C and its antecedent are true, free will is possible. Ned Markosian has provided the Compatibilist with yet another response to UR-based objections to her view, wedding it to the notion of agent causation: here the deterministic causing of an act by its agent is necessary and sufficient for its being “morally free.” I criticize this view as inconsistent with the agent causalist's belief that moral responsibility precludes causation of a choice by any power other than the maker thereof: he being its efficient cause.

Since his Metaphysische Anfangsgründe der Naturwissenschaft was first published in 1786, controversy has surrounded Immanuel Kant’s conception of matter. In particular, the justification for both his dynamical theory of matter and the related dismissal of mechanical philosophy are obscure. In this paper, I address these longstanding issues and establish that Kant’s dynamism rests upon Leibnizian, metaphysical commitments held by Kant from his early pre-Critical texts on natural philosophy to his major critical works. I demonstrate that, throughout his corpus and inspired (...) by Leibniz, Kant endorses the a priori law of continuity of alteration as a truth of metaphysics, according to which all alterations in experience must occur gradually through all intervening degrees. The principle thus legislates against mechanical philosophy’s absolutely impenetrable atoms, as they would would involve instantaneous changes of velocity in impact. This reveals the metaphysical incoherencies in mechanical philosophy and leaves Kant’s own dynamical theory of matter, grounded on material forces, as the only viable approach to physical explanation. Subsequently, I demonstrate that Kant nevertheless made conceptual space in his system for the theoretical consideration of mechanical explanations, which makes manifest one of the positive roles that the faculty of reason can play with respect to natural science.

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 world, (...) then no being in such a world could entertain the thought that a timeless theory is true, let alone believe such a theory or rationally believe it. This paper investigates the options for understanding representation in a three-dimensional, timeless, world. Ultimately it concludes that the only viable option is one according to which representation is taken to be deeply non-naturalistic. Ironically then we are left with two seemingly very unattractive options. Either a very naturalistic motivation—taking seriously a live view in fundamental physics—leads us to a very non-naturalistic view of the mental, or else views in the philosophy of mind partly dictate what is an acceptable theory in physics.

My two daughters would love to go tobogganing down the hill by themselves, but they are just toddlers and I am an apprehensive parent, so, before letting them do so, I want to ensure that the toboggan won’t go too fast. But how fast will it go? One way to try to answer this question would be to tackle the problem head on. Since my daughters and their toboggan are initially at rest, according to classical mechanics, their final velocity (...) will be determined by the forces they will be subjected to between the moment the toboggan will be released at the top of the hill and the moment it will reach its highest speed. The problem is that, throughout their downhill journey, my daughters and the toboggan will be subjected to an incredibly large number of forces—from the gravitational pull of any massive object in the universe to the weight of the snowflake that is sitting on the tip of one of my youngest daughter’s hairs—so that any attempt to apply the theory directly to the real-world system in all its complexity seems to be doomed to failure.

Relativity theory is often said to support something called ‘the four-dimensional view of reality’. But there are at least three different views that sometimes go by this name. One is ‘spacetime unitism’, according to which there is a spacetime manifold, and if there are such things as points of space or instants of time, these are just spacetime regions of different sorts: thus space and time are not separate manifolds. A second is the B-theory of time, according to which the (...) past, present, and future are all equally real and there is nothing metaphysically special about the present. A third is perdurantism, according to which persisting material objects are made up of different temporal parts located at different times. We sketch routes from relativity to unitism and to the B-theory. We then discuss some routes to perdurantism, via the B-theory and via unitism. (shrink)

Some argue that time’s causal arrow is grounded in an underlying thermodynamic asymmetry. Often, this is tied to Humean skepticism that causes produce their effects, in any robust sense of ‘produce’. Conversely, those who advocate stronger notions of natural necessity often reject thermodynamic reductions of time’s causal arrow. Against these traditional pairings, I argue that ‘reduction-plus-production’ is coherent. Reductionists looking to invoke robust production can insist that there are metaphysical constraints on the signs of objects’ velocities in any state, given (...) other—including far later—states’ properties. The Past Hypothesis may thus be a metaphysical condition, not a physical law. (shrink)

La democracia en el texto es vista desde una perspectiva integral u onmicomprensiva que complementa la parte instrumental (procedimiento electoral) con la sustancial (goce efectivo de derechos humanos) basado en la concienciación de una real dignidad humana que permita que la persona realice su proyecto de vida, disfrute de sus derechos y funcione efectivamente en la sociedad dentro del Estado democrático constitucional: la interrelación e interdependencia entre democracia, dignidad humana y Estado constitucional de derecho resulta para el autor un norte (...) el cual hay que seguir a cada instante. El libro muestra la importancia de la dogmática actual de la Corte Constitucional colombiana sobre derechos fundamentales, lo cual es un aporte latinoamericano a la estructuración de un constitucionalismo que contribuya con soluciones a favor de la libertad y la justicia en función de la persona humana en un escenario de tensiones evidentes entre la globalización y nacionalismos populistas y patrioteros. En el sentido expresado en el punto anterior la obra del profesor Caldera corrobora la relevancia que dicha dogmática le atribuye a la funcionalidad de los DerechosFundamentales con el logro del contenido normativo de la dignidad humana. Así, para Caldera Ynfante y desde su especial interpretación de la democracia cumple con los requisitos dogmáticos entronizados por la Corte Constitucional para ser considerado como un derecho fundamental generador de todos los efectos instrumentales y sustanciales que le son señalados. El texto nos lleva a establecer conceptualmente con un propósito práctico que la democracia integral, es decir, entendida como derecho fundamental es posible asumirla desde la perspectiva de la denominada teoría de la integralidad de los DDHH a partir de la Declaración y Plan de Acción de Viena sobreDDHH de 1993, instrumento del derecho internacional que resulta apical a partir del cual considera como fundamentales todos los Derechos Humanos. En consecuencia para el autor la democracia integral, como derecho fundamental, es posible asumirla desde la perspectiva del Enfoque Basado enDDHH y así puede ser defendida ante cualquier sistema de protección, ora universal o regional. Por otra parte es necesario para el lector reflexionar en torno al sentido de una democracia integral que para el autor es asumida como una meta garantía de losDDHH; es decir, como el derecho fundamental de los derechos fundamentales.

An Intelligent Tutoring System (ITS) is a computer system that offers an instant, adapted instruction and customized feedback to students without human teacher interference. Reciting "Tajweed" the Holy Quran in the appropriate way is very important for all Muslims and is obligatory in Islamic devotions such as prayers. In this paper, the researchers introduce an intelligent tutoring system for teaching Reciting "Tajweed". Our "Tajweed" tutoring system is limited to "Tafkhim and Tarqiq in TAJWEED" the Holy Quran, Rewaya: Hafs from (...) ‘Aasem. The system was evaluated by reciting teachers and students, and the results were auspicious. (shrink)

Many philosophers of physics think that physical rates of change, like velocity or acceleration in classical physics, are extrinsic. Many philosophers of mind think that phenomenal properties, which characterize what it’s like to be an agent at a time, are intrinsic. I will argue that these two views can’t both be true. Given that these two views are in tension, we face an explanatory challenge. Why should there be any interesting connection between these physical quantities and consciousness in the (...) first place? In a speculative spirit, I close by developing a panpsychist view which promises to explain this connection in a particularly satisfying way. (shrink)

Suppose that you're lying in bed. You just woke up. But you're alert. Your mind is clear and you have no distractions. As you lie there, you think to yourself, ‘2 + 2 = 4.’ The thought just pops into your head. But, wanting to be sure of your mathematical insight, you once again think ‘2 + 2 = 4’, this time really meditating on your thought. Now suppose that you're sitting in an empty movie theatre. The lighting is normal (...) and the screen in front of you is blank. Then at some point an image of a peach is flashed on the screen. The image isn't up there for long. In fact, it's only on the screen for what seems like an instant—just long enough for you to see it. These two scenarios are a bit mundane. But, as I will show, reflection on them can yield significant results concerning the nature of persons and their persistence through time. First I will show that thought and perception have temporal constraints whereby your thinking or perceiving in the above scenarios implies that you exist through a temporally.. (shrink)

Those inclined to positions in the philosophy of time that take tense seriously have typically assumed that not all regions of space-time are equal: one special region of space-time corresponds to what is presently happening. When combined with assumptions from modern physics this has the unsettling consequence that the shape of this favored region distinguishes people in certain places or people traveling at certain velocities. In this paper I shall attempt to avoid this result by developing a tensed picture of (...) reality that is nonetheless consistent with ‘hypersurface egalitarianism’—the view that all hypersurfaces are equal.

The paper considers the symmetries of a bit of information corresponding to one, two or three qubits of quantum information and identifiable as the three basic symmetries of the Standard model, U(1), SU(2), and SU(3) accordingly. They refer to “empty qubits” (or the free variable of quantum information), i.e. those in which no point is chosen (recorded). The choice of a certain point violates those symmetries. It can be represented furthermore as the choice of a privileged reference frame (e.g. that (...) of the Big Bang), which can be described exhaustively by means of 16 numbers (4 for position, 4 for velocity, and 8 for acceleration) independently of time, but in space-time continuum, and still one, 17th number is necessary for the mass of rest of the observer in it. The same 17 numbers describing exhaustively a privileged reference frame thus granted to be “zero”, respectively a certain violation of all the three symmetries of the Standard model or the “record” in a qubit in general, can be represented as 17 elementary wave functions (or classes of wave functions) after the bijection of natural and transfinite natural (ordinal) numbers in Hilbert arithmetic and further identified as those corresponding to the 17 elementary of particles of the Standard model. Two generalizations of the relevant concepts of general relativity are introduced: (1) “discrete reference frame” to the class of all arbitrarily accelerated reference frame constituting a smooth manifold; (2) a still more general principle of relativity to the general principle of relativity, and meaning the conservation of quantum information as to all discrete reference frames as to the smooth manifold of all reference frames of general relativity. Then, the bijective transition from an accelerated reference frame to the 17 elementary wave functions of the Standard model can be interpreted by the still more general principle of relativity as the equivalent redescription of a privileged reference frame: smooth into a discrete one. The conservation of quantum information related to the generalization of the concept of reference frame can be interpreted as restoring the concept of the ether, an absolutely immovable medium and reference frame in Newtonian mechanics, to which the relative motion can be interpreted as an absolute one, or logically: the relations, as properties. The new ether is to consist of qubits (or quantum information). One can track the conceptual pathway of the “ether” from Newtonian mechanics via special relativity, via general relativity, via quantum mechanics to the theory of quantum information (or “quantum mechanics and information”). The identification of entanglement and gravity can be considered also as a ‘byproduct” implied by the transition from the smooth “ether of special and general relativity’ to the “flat” ether of quantum mechanics and information. The qubit ether is out of the “temporal screen” in general and is depicted on it as both matter and energy, both dark and visible. (shrink)

Lady Mary Shepherd holds that the relation of cause and effect consists of the combination of two objects to create a third object. She also holds that this account implies that causes are synchronous with their effects. There is a single instant in which the objects that are causes combine to create the object which is their effect. Hume argues that cause and effect cannot be synchronous because if they were then the entire chain of successive causes and effects (...) would all collapse into a single moment, and succession would not be possible. I argue that Shepherd has a ready, although implicit response, to Hume’s argument. Since causation is combination on Shepherd’s view, she is free to hold that there are times in between those instants in which combinations occur, during which times other, non-combinatory changes occur, which changes account for succession.

The Internet has been identified in human enhancement scholarship as a powerful cognitive enhancement technology. It offers instant access to almost any type of information, along with the ability to share that information with others. The aim of this paper is to critically assess the enhancement potential of the Internet. We argue that unconditional access to information does not lead to cognitive enhancement. The Internet is not a simple, uniform technology, either in its composition, or in its use. We (...) will look into why the Internet as an informational resource currently fails to enhance cognition. We analyze some of the phenomena that emerge from vast, continual fluxes of information–information overload, misinformation and persuasive design—and show how they could negatively impact users’ cognition. Methods for mitigating these negative impacts are then advanced: individual empowerment, better collaborative systems for sorting and categorizing information, and the use of artificial intelligence assistants that could guide users through the informational space of today’s Internet.

We propose a modular ontology of the dynamic features of reality. This amounts, on the one hand, to a purely spatial ontology supporting snapshot views of the world at successive instants of time and, on the other hand, to a purely spatiotemporal ontology of change and process. We argue that dynamic spatial ontology must combine these two distinct types of inventory of the entities and relationships in reality, and we provide characterizations of spatiotemporal reasoning in the light of the interconnections (...) between them.

The standard model of precedential constraint holds that a court is equally free to modify a precedent of its own and a precedent of a superior court—overruling aside, it does not differentiate horizontal and vertical precedents. This paper shows that no model can capture the U.S. doctrine of precedent without making that distinction. A precise model is then developed that does just that. This requires situating precedent cases in a formal representation of a hierarchical legal structure, and adjusting the constraint (...) that a precedent imposes based on the relationship of the precedent court and the instant court. The paper closes with suggestions for further improvements of the model. (shrink)

In this paper I develop a version of universalism that is non-mereological. Broadly speaking, non-mereological universalism is the thesis that for any arbitrary set of objects and times, there is a persisting object which, at each of those times, will be constituted by those of the objects that exist at that time. I consider two general versions of non-mereological universalism, one which takes basic simples to be enduring objects, and the other which takes simples to be instantaneous objects. This yields (...) three versions of endurantism, of which I ultimately defend the version I call universalist endurantism. Universalist endurantism is the thesis that for any arbitrary set S of instantaneous simples that exist at the same instant, there exists a fusion of the members of S, and for any arbitrary set S* of instantaneous fusions each of which exist at a different instant, there exists an enduring object O that is constituted by those fusions at those instants. Universalist endurantism is ‘non-mereological’ in that the relation that holds between instantaneous fusions and persisting objects is not the part/whole relation, but rather, is the relation of constitution, thus allowing that the persisting objects are three rather than four dimensional. I argue that universalist endurantism not only has the various benefits of mereological universalism in allowing vagueness to be explicated as semantic indeterminacy, but in addition allows the endurantist to hold that some properties are genuinely intrinsic and are exemplified simpliciter.

This paper empirically investigates the contention that the folk concept of time is a functional concept: a concept according to which time is whatever plays a certain functional role or roles. This hypothesis could explain why, in previous research, surprisingly large percentages of participants judge that there is time at worlds that contain no one-dimensional substructure of ordered instants. If it seems to participants that even in those worlds the relevant functional role is played, then this could explain why they (...) judge that there is time in those worlds. While our experiment supported the finding that participants are reticent to judge that there is no time, actually, we found no evidence that this is because they deploy a functionalist concept, at least of the kind proposed in recent research. Our findings are, however, consistent with the folk deploying a much more minimal functionalist concept according to which time is just whatever it is—regardless of its nature—that plays the role of grounding our temporal phenomenology.

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 paper aims to investigate the temporal content of perceptual experience. It argues that we must recognize the existence of temporal perceptions, i.e., perceptions the content of which cannot be spelled out simply by looking at what is the case at an isolated instant. Acts of apprehension can cover a succession of events. However, a subject who has such perceptions can fall short of having a concept of time. Similar arguments have been put forward to show that a subject (...) who has spatial perceptions can fall short of having a concept of space. In both cases, it is the fact that perception is from a point of view which stands in the way of it constituting an exercise of a concept of how things are objectively. However, the paper also shows that the way in which perception is perspectival takes a different form in each of the two cases. (shrink)
