  1. O afrykańskim stanie rzeczy. Analiza teorii systemu autorstwa Paulina J. Hountondji'ego.Krzysztof Trzcinski - 2011 - In A. Żukowski (ed.), Problem bogactwa i biedy we współczesnej Afryce. Olsztyn: pp. 393-413.
    Beniński filozof Paulin J. Hountondji jest autorem teorii systemu, która aspiruje do przynajmniej częściowego wytłumaczenia przyczyn złej kondycji afrykańskich społeczeństw i państw. Afrykański społeczno-polityczny stan rzeczy charakteryzuje, zdaniem Hountondjiego, przede wszystkim wadliwa organizacja struktur instytucjonalnych państw oraz codziennego życia Afrykanów. Hountondji krytykuje liczne wady afrykańskiej rzeczywistości - w tym inercję instytucji, działania pełne absurdów, marnowanie czasu, energii i zdrowia - i zarazem poszukuje ich ukrytych, „systemowych” podstaw. W rozumieniu Hountondjiego, system to zbiór wzajemnie ze sobą powiązanych elementów organizacji afrykańskich społeczeństw. (...)

  2. A Critique of Susanne Langer’s View of Musical Temporality.Eran Guter & Inbal Guter - 2018 - Proceedings of the European Society for Aesthetics, Vol. 10.
    Susanne Langer’s idea of the primary apparition of music involves a dichotomy between two kinds of temporality: “felt time” and “clock time.” For Langer, musical time is exclusively felt time, and in this sense, music is “time made audible.” However, Langer also postulates what we would call ‘a strong suspension thesis’: the swallowing up of clock time in the illusion of felt time. In this paper we take issue with the ‘strong suspension thesis’ and its implications and ramifications regarding not (...)

  3. The Puzzle of the Changing Past.Luca Barlassina & Fabio Del Prete - 2015 - Analysis 75 (1):59-67.
    If you utter sentence ‘Obama was born in 1961’ now, you say something true about the past. Since the past will always be such that the year 1961 has the property of being a time in which Obama was born, it seems impossible that could ever be false in a future context of utterance. We shall consider the case of a sentence about the past exactly like , but which was true when uttered a few years ago and is no (...)

  4. The Mathematical Representation of the Arrow of Time.Meir Hemmo & Orly Shenker - 2012 - Iyyun 61:167-192.
    This paper distinguishes between 3 meanings of reversal, all of which are mathematically equivalent in classical mechanics: velocity reversal, retrodiction, and time reversal. It then concludes that in order to have well defined velocities a primitive arrow of time must be included in every time slice. The paper briefly mentions that this arrow cannot come from the Second Law of thermodynamics, but this point is developed in more details elsewhere.

  2. From Time Asymmetry to Quantum Entanglement: The Humean Unification.Eddy Keming Chen - manuscript
    Two of the most difficult problems in the philosophical foundations of physics are (1) what gives rise to the arrow of time and (2) what the ontology of quantum mechanics is. The first problem is puzzling since the fundamental dynamical laws of physics do not include an arrow of time. The second problem is puzzling since the quantum-mechanical wave function describes a non-separable reality that is remarkably different from the objects in our ordinary experiences. In this paper, we propose a (...)

  3. Primitive Directionality and Diachronic Grounding.Naoyuki Kajimoto, Kristie Miller & James Norton - 2020 - Acta Analytica 35 (2):195-211.
    Eternalists believe that there is no ontological difference between the past, present and future. Thus, a challenge arises: in virtue of what does time have a direction? Some eternalists, Oaklander and Tegtmeier ) argue that the direction of time is primitive. A natural response to positing primitive directionality is the suspicion that said posit is too mysterious to do any explanatory work. The aim of this paper is to relieve primitive directionality of some of its mystery by offering a novel (...)

  4. Are the Notions of Past, Present and Future Compatible with the General Theory of Relativity?Daniel David Sega Neuman & Daniel Galviz - manuscript
    The notions of time and causality are revisited, as well as the A- and B-theory of time, in order to determine which theory of time is most compatible with relativistic spacetimes. By considering orientable spacetimes and defining a time-orientation, we formalize the concepts of a time-series in relativistic spacetimes; A-theory and B-theory are given mathematical descriptions within the formalism of General Relativity. As a result, in time-orientable spacetimes, the notions of events being in the future and in the past, which (...)

  5. An Empirical Investigation of the Role of Direction in Our Concept of Time.Andrew James Latham, Kristie Miller & James Norton - forthcoming - Acta Analytica:1-23.
    This paper empirically investigates one aspect of the folk concept of time (amongst US residents), by testing how the presence or absence of directedness impacts judgements about whether there is time in a world. Experiment 1 found that dynamists (those who think the actual world contains an A-series), showed significantly higher levels of agreement that there is time in dynamically directed (growing block) worlds than in non-dynamical non-directed (C-theory) worlds. Comparing our results to those of Latham et al. (ms), we (...)

  6. Causation and Time Reversal.Matt Farr - 2016 - British Journal for the Philosophy of Science 71 (1):177-204.
    What would it be for a process to happen backwards in time? Would such a process involve different causal relations? It is common to understand the time-reversal invariance of a physical theory in causal terms, such that whatever can happen forwards in time can also happen backwards in time. This has led many to hold that time-reversal symmetry is incompatible with the asymmetry of cause and effect. This article critiques the causal reading of time reversal. First, I argue that the (...)

  7. Time's Arrow in a Quantum Universe: On the Status of Statistical Mechanical Probabilities.Eddy Keming Chen - forthcoming - In Valia Allori (ed.), Statistical Mechanics and Scientific Explanation: Determinism, Indeterminism and Laws of Nature. World Scientific.
    In a quantum universe with a strong arrow of time, it is standard to postulate that the initial wave function started in a particular macrostate---the special low-entropy macrostate selected by the Past Hypothesis. Moreover, there is an additional postulate about statistical mechanical probabilities according to which the initial wave function is a ''typical'' choice in the macrostate. Together, they support a probabilistic version of the Second Law of Thermodynamics: typical initial wave functions will increase in entropy. Hence, there are two (...)

  8. Counterfactuals, Irreversible Laws and The Direction of Time.Terrance A. Tomkow - manuscript
    The principle of Information Conservation or Determinism is a governing assumption of physical theory. Determinism has counterfactual consequences. It entails that if the present were different, then the future would be different. But determinism is temporally symmetric: it entails that if the present were different, the past would also have to be different. This runs contrary to our commonsense intuition that what has happened in the future depends on the past in a way the past does not depend on the (...)

  9. A Study of Time in Modern Physics.Peter W. Evans - 2011 - Dissertation,
    This thesis is a study of the notion of time in modern physics, consisting of two parts. Part I takes seriously the doctrine that modern physics should be treated as the primary guide to the nature of time. To this end, it offers an analysis of the various conceptions of time that emerge in the context of various physical theories and, furthermore, an analysis of the relation between these conceptions of time and the more orthodox philosophical views on the nature (...)

  10. Temporal Phenomenology: Phenomenological Illusion Versus Cognitive Error.Kristie Miller, Alex Holcombe & Andrew James Latham - 2020 - Synthese 197 (2):751-771.
    Temporal non-dynamists hold that there is no temporal passage, but concede that many of us judge that it seems as though time passes. Phenomenal Illusionists suppose that things do seem this way, even though things are not this way. They attempt to explain how it is that we are subject to a pervasive phenomenal illusion. More recently, Cognitive Error Theorists have argued that our experiences do not seem that way; rather, we are subject to an error that leads us mistakenly (...)

  11. Time Reversal Invariance in Quantum Mechanics.Reza Moulavi Ardakani - 2017 - Dissertation, Texas Tech University
    Symmetries have a crucial role in today’s physics. In this thesis, we are mostly concerned with time reversal invariance (T-symmetry). A physical system is time reversal invariant if its underlying laws are not sensitive to the direction of time. There are various accounts of time reversal transformation resulting in different views on whether or not a given theory in physics is time reversal invariant. With a focus on quantum mechanics, I describe the standard account of time reversal and compare it (...)

  12. The Identification of the Intrinsic Nature of Time.Vincent Vesterby - 2014
    For millennia people have speculated about the nature of time—without success. Time plays a role with all processes and events studied by all the disciplines. It is reported here that the existence of time is a direct consequence of the existence of space. Space exists, and it continues to exist. Space is there, and it continues to be there. Space exists as place, the three-dimensional place that matter can occupy. The three-dimensional extension of spatial-place is measured with a ruler of (...)

  13. What’s So Spatial About Time Anyway?Sam Baron & Peter W. Evans - forthcoming - British Journal for the Philosophy of Science:axy077.
    Skow ([2007]), and much more recently Callender ([2017]), argue that time can be distinguished from space due to the special role it plays in our laws of nature: our laws determine the behaviour of physical systems across time, but not across space. In this work we assess the claim that the laws of nature might provide the basis for distinguishing time from space. We find that there is an obvious reason to be sceptical of the argument Skow submits for distinguishing (...)

    The Simulation Hypothesis proposes that all of reality is an artificial simulation, analogous to a computer simulation. Outlined here is a low computational cost method for programming cosmic microwave background parameters in Planck time Simulation Hypothesis Universe. The model initializes `micro Planck-size black-holes' as entities that embed the Planck units. For each incremental unit of Planck time, the universe expands by adding 1 micro black-hole, a dark energy is not required. The mass-space parameters increment linearly, the electric parameters in a (...)

    The central motivating idea behind the development of this work is the concept of prespace, a hypothetical structure that is postulated by some physicists to underlie the fabric of space or space-time. I consider how such a structure could relate to space and space-time, and the rest of reality as we know it, and the implications of the existence of this structure for quantum theory. Understanding how this structure could relate to space and to the rest of reality requires, I (...)

  19. Tensed Ontology Based on Simple Partial Logic.Daisuke Kachi - 2002 - Proceedings of Ninth International Symposium on Temporal Representation and Reasoning: TIME-02:141-145.
    Simple partial logic (=SPL) is, broadly speaking, an extensional logic which allows for the truth-value gap. First I give a system of propositional SPL by partializing classical logic, as well as extending it with several non-classical truth-functional operators. Second I show a way based on SPL to construct a system of tensed ontology, by representing tensed statements as two kinds of necessary statements in a linear model that consists of the present and future worlds. Finally I compare that way with (...)

  20. The Time Flow Manifesto CHAPTER 3 REVERSIBILTY IN PHYSICS.Andrew Holster - manuscript
    The conventional claims and concepts of 5* - 8* are a hang-over from the classical theory of thermodynamics – i.e. thermodynamics based on a fully deterministic micro-theory, developed in the time of Boltzmann, Loschmidt and Gibbs in the late C19th. The classical theory has well-known ‘reversibility paradoxes’ when applied to the universe as a whole. But the introduction of intrinsic probabilities in quantum mechanics, and its consequent time asymmetry, fundamentally changes the picture.

    The inevitability of arising in equations of kinetics and hydrodynamics irreversibility not contained in original equations of classic mechanics is substantiated. It is established that transfer of information about the direction of system evolution from initial conditions to resulting equations is the consequence of losing information about the position of an individual particle in space, which takes place at roughening description. It is shown that the roughening with respect to impact parameters of colliding particles is responsible for appearance of the (...)

These are the foundational principles of the conventional philosophy, which developed in the mid-C20th from positivist-inspired studies. The first chapter begins by (...)

    Statistical physics cannot explain why a thermodynamic arrow of time exists, unless one postulates very special and unnatural initial conditions. Yet, we argue that statistical physics can explain why the thermodynamic arrow of time is universal, i.e., why the arrow points in the same direction everywhere. Namely, if two subsystems have opposite arrow-directions at a particular time, the interaction between them makes the configuration statistically unstable and causes a decay towards a system with a universal direction of the arrow of (...)

    Bertrand Russell famously argued that causation is not part of the fundamental physical description of the world, describing the notion of cause as “a relic of a bygone age”. This paper assesses one of Russell’s arguments for this conclusion: the ‘Directionality Argument’, which holds that the time symmetry of fundamental physics is inconsistent with the time asymmetry of causation. We claim that the coherence and success of the Directionality Argument crucially depends on the proper interpretation of the ‘ time symmetry’ (...)

    Backtracking influence is influence that zigzags in time. For example, backtracking influence exists when an event E_1 makes an event E_2 more likely by way of a nomic connection that goes from E_1 back in time to an event C and then forward in time to E_2. I contend that in our local region of spacetime, at least, backtracking influence is redundant in the sense that any existing backtracking influence exerted by E_1 on E_2 is equivalent to E_1's temporally direct (...)

    The future is different from the past. What is past is fixed and set in stone. The future, on the other hand, is open insofar as it holds numerous possibilities. Branching-tree models of time account for this asymmetry by positing an ontological difference between the past and the future. Given a time t, a unique unified past lies behind t, whereas multiple alternative existing futures lie ahead of t. My goal in this paper is to show that there is an (...)

    Certains scientifiques et philosophes sont d’avis que toute théorie permettant un voyage dans le temps introduirait des problèmes de causalité. Ces types de paradoxes temporels peuvent être évités grâce au principe de cohérence de Novikov ou à une variation de l'interprétation des mondes multiples avec des mondes en interaction. L'argument classique contre la causalité rétrograde est l'argument du contournement.

    Orice teorie care ar permite călătoria în timp ar introduce probleme de cauzalitate. Aceste tipuri de paradoxuri temporale pot fi evitate prin principiul de consecvență Novikov sau printr-o variație a interpretării multor lumi cu lumi care interacționează. Argumentul clasic împotriva cauzalității înapoi este argumentul bilking, Dacă un eveniment A provoacă un eveniment anterior B, bilking recomandă o încercare de a decorela A și B, adică de a aduce A în cazurile în care B nu a avut loc și de a (...)

  6. Multilocation Without Time Travel.Justin Mooney - forthcoming - Erkenntnis:1-14.
    Some philosophers defend the possibility of synchronic multilocation, and have even used it to defend other substantive metaphysical theses. But just how strong is the case for the possibility of synchronic multilocation? The answer to this question depends in part on whether synchronic multilocation is wedded to other controversial metaphysical notions. In this paper, I consider whether the possibility of synchronic multilocation depends on the possibility of time travel, and I conclude that the answer hinges on the nature of time (...)

  8. Călătorii în timp.Nicolae Sfetcu - 2018 - Drobeta Turnu Severin: MultiMedia Publishing.
    Există teorii recente, inclusiv despre găurile de vierme, care permit călătoriile în timp. În cazul găurii de vierme. aceasta ar fi posibil accelerând unul din capetele găurii de vierme la o viteză mult mai mare decât celălalt capăt şi aducându-le, la un moment ulterior, în starea iniţială. Ar rezulta de aici o dilatare relativistă a timpului la capătul accelerat al găurii de vierme, timpul scurgându-se aici mai încet decât la celălalt capăt staţionar din punctul de vedere al unui observator extern, (...)

  9. La philosophie du voyage dans le temps.Nicolae Sfetcu - manuscript
    L'éternalisme soutient que le passé et le futur existent réellement, en partant de l’idée que le temps est une dimension similaire aux dimensions spatiales, que les événements passés et futurs sont « présents » sur l’axe du temps, mais cette opinion est contestée. Dans la vision à quatre dimensions, l'univers est une topologie espace-temps existante, contenant tout ce qui s'est passé, tout ce qui se passe et tout ce qui va se passer. Il en résulte qu'il n'y a aucun moment (...)

  10. Filosofia călătoriei în timp – Paradoxul bunicului.Nicolae Sfetcu - manuscript
    Newton a susținut ideea timpului absolut, spre deosebire de Leibniz pentru care timpul este doar o relație între evenimente și nu poate fi exprimat în mod independent, afirmație în concordanță ci relativitatea spațiu-timpului. Eternismul susține că trecutul și viitorul există într-un sens real, mergându-se până la ideea că timpul este o dimensiune similară cu dimensiunile spațiale, că evenimentele viitoare și trecute sunt "prezente" pe axa timpului, dar această opinie este contestată. Cel mai cunoscut exemplu de imposibilitate a călătoriei în timp (...)
