About this topic
Summary

That things appear to be different across times when looking from earlier to later as opposed to from later to earlier is what it is for time to be anisotropic. But this alone doesn’t mean that time has a direction. Time has a direction if and only if there is an objective fact as to whether or not time goes from earlier to later or later to earlier. From this starting assumption, there are two core debates in the literature. The first is whether or not time has a direction. A-theorists and B-theorists hold that time has an objective direction, whereas C-theorists deny this. For those who think time does have a direction, then, there is the further disagreement about whether direction is an intrinsic or extrinsic feature of time. For the A-theorist, the directionality is intrinsic to time and is grounded in temporal passage, or objective becoming – i.e., time is directed from the past to the future because time passes as which moment is present changes. Some B-theorists likewise hold that direction is an intrinsic feature of time but that it is grounded in some B-theoretic feature, rather than temporal passage. On the other hand, other B-theorists make the stronger claim that the direction of time is reducible to B-theoretic features and is therefore extrinsic to time. The second core debate, then, is amongst those who hold that the direction of time is merely extrinsic. Put simply, the problem is how the temporal asymmetries that exist in the world can be accounted for, given that the laws of nature are time reversal invariant – i.e., hold even if the order of times were reversed. So called reductionist B-theorists have appealed to a few features of the universe in order to explain the directedness of time. They include the expansion of the universe, increase in entropy over time, causal order, and the fact that we deliberate about future events but not past events.

  1. 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.

  2. Two-Dimensional Time.Michael Kowalik - manuscript
    Philosophical views about the logical structure of time are typically divided between proponents of A and B theories, based on McTaggart's A and B series. Drawing on Paul Ricoeur's hermeneutic phenomenology, I develop and defend McTaggart's thesis that the C series and the A series working together give a consistent description of temporal experience, provided that the two series are treated as distinct dimensions internal to time. In the proposed two-dimensional model, the C series expresses a nesting order of the (...)

    This report offers a modern perspective on the question of time directionality as it arises in a classical and quantum mechanical context, based on key developments in the field of gravitational physics. Important clarifications are achieved regarding, in particular, the concepts of time reversal, negative energy and causality. From this analysis emerges an improved understanding of the general relativistic concept of stress-energy of matter as being a manifestation of local variations in the energy density of zero-point vacuum fluctuations.

    Joe Campbell has identified an apparent flaw in van Inwagen’s Consequence Argument. It apparently derives a metaphysically necessary conclusion from what Campbell argues is a contingent premise: that the past is in some sense necessary. I criticise Campbell’s examples attempting to show that this is not the case (in the requisite sense) and suggest some directions along which an incompatibilist could reconstruct her argument so as to remain immune to Campbell’s worries.

    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 (...)

    One of the most difficult problems in the foundations of physics is what gives rise to the arrow of time. Since the fundamental dynamical laws of physics are (essentially) symmetric in time, the explanation for time's arrow must come from elsewhere. A promising explanation introduces a special cosmological initial condition, now called the Past Hypothesis: the universe started in a low-entropy state. Unfortunately, in a universe where there are many copies of us (in the distant ''past'' or the distant ''future''), (...)

    If the Past Hypothesis underlies the arrows of time, what is the status of the Past Hypothesis? In this paper, I examine the role of the Past Hypothesis in the Boltzmannian account and defend the view that the Past Hypothesis is a candidate fundamental law of nature. Such a view is known to be compatible with Humeanism about laws, but as I argue it is also supported by a minimal non-Humean "governing'' view. Some worries arise from the non-dynamical and time-dependent (...)

The metaphysics can place demands on the proper formulations of physical theories. It is sometimes assumed that the governing view requires a fundamental / intrinsic direction of time: to govern, laws must be dynamical, producing later states of the world from earlier ones, in accord with the fundamental direction of (...)

    Two of the most difficult problems in the foundations of physics are (1) what gives rise to the arrow of time and (2) what the ontology of quantum mechanics is. I propose a unified 'Humean' solution to the two problems. Humeanism allows us to incorporate the Past Hypothesis and the Statistical Postulate into the best system, which we then use to simplify the quantum state of the universe. This enables us to confer the nomological status to the quantum state in (...)

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 (...)

    What exists at the fundamental level of reality? On the standard picture, the fundamental reality contains (among other things) fundamental matter, such as particles, fields, or even the quantum state. Non-fundamental facts are explained by facts about fundamental matter, at least in part. In this paper, I introduce a non-standard picture called the "cosmic void” in which the universe is devoid of any fundamental material ontology. Facts about tables and chairs are recovered from a special kind of laws that satisfy (...)

But how does a temporally adirectional metaphysics, or ‘C-theory’ of time, fit with the time of experience? In this chapter, I look at what kind of problem human time poses for C-theories. First, I ask whether there is a ‘hard problem’ of human time: whether it is in principle impossible to have the kinds of experience we do in a temporally adirectional world. Second I consider (...)

    It is often said that the world is explained by laws of nature together with initial conditions. But does that mean initial conditions don’t require further explanation? And does the explanatory role played by initial conditions entail or require that time has a preferred direction? This chapter looks at the use of the ‘initialness defence’ in physics, the idea that initial conditions are intrinsically special in that they don’t require further explanation, unlike the state of the world at other times.

    We standardly evaluate counterfactuals and abilities in temporally asymmetric terms—by keeping the past fixed and holding the future open. Only future events depend counterfactually on what happens now. Past events do not. Conversely, past events are relevant to what abilities one has now in a way that future events are not. Lewis, Sider and others continue to evaluate counterfactuals and abilities in temporally asymmetric terms, even in cases of backwards time travel. I’ll argue that we need more temporally neutral methods. (...)

One reason is that these definitions rest on an ontological question—‘Do the future and the past exist?’—to which no non-speculative answer can be provided. Another reason is that these definitions fail to distinguish between various A-theories of time at all times and, therefore, cannot be regarded as essential to them.

    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 (...)

    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 (...)

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 (...)

    What is the proper metaphysics of quantum mechanics? In this dissertation, I approach the question from three different but related angles. First, I suggest that the quantum state can be understood intrinsically as relations holding among regions in ordinary space-time, from which we can recover the wave function uniquely up to an equivalence class (by representation and uniqueness theorems). The intrinsic account eliminates certain conventional elements (e.g. overall phase) in the representation of the quantum state. It also dispenses with first-order (...)

    There seems to be a distinctive way in which we can remember events we have experienced ourselves, which differs from the capacity to retain information about events that we can also have when we have not experienced those events ourselves but just learned about them in some other way. Psychologists and increasingly also philosophers have tried to capture this difference in terms of the idea of two different types of memory: episodic memory and semantic memory. Yet, the demarcation between episodic (...)

I will argue that positing such a direction of time, in addition to time-asymmetric boundary conditions, enables a (...)

    I argue that Mumford and Anjum’s recent theory of simultaneous causation among powerful meso-level objects is problematic in several respects: it is based on a false dichotomy, it is incompatible with standard meso-level physics, it is explanatory deficient, and it threatens to render the powers metaphysics incoherent. Powers theorists are advised, therefore, to adopt a purely sequential conception of causation.

  41. Backtracking Counterfactuals Revisited.Justin Khoo - 2017 - Mind 126 (503):841-910.
    I discuss three observations about backtracking counterfactuals not predicted by existing theories, and then motivate a theory of counterfactuals that does predict them. On my theory, counterfactuals quantify over a suitably restricted set of historical possibilities from some contextually relevant past time. I motivate each feature of the theory relevant to predicting our three observations about backtracking counterfactuals. The paper concludes with replies to three potential objections.

  42. The Asymmetry of Counterfactual Dependence.Christian Loew - 2017 - Philosophy of Science 84 (3):436-455.
    A certain type of counterfactual is thought to be intimately related to causation, control, and explanation. The time asymmetry of these phenomena therefore plausibly arises from a time asymmetry of counterfactual dependence. But why is counterfactual dependence time asymmetric? The most influential account of the time asymmetry of counterfactual dependence is David Albert’s account, which posits a new, time-asymmetric fundamental physical law, the so-called “past hypothesis.” Albert argues that the time asymmetry of counterfactual dependence arises from holding fixed the past (...)

  43. A Blast From The Past.Kristie Miller - 2017 - The Philosophers' Magazine 77:82-86.
    That we find the idea of travelling in time, and in particular travelling backwards in time, fascinating, is evidenced by the plethora of new science fictions shows depicting time travel that hit our TV screens in 2016. I love time travel shows, and I can hardly keep up. In almost all cases these shows depict what philosophers call inconsistent time travel stories: stories that commit what my colleague Nick Smith (The University of Sydney) calls the second time around fallacy. These (...)

  44. 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 (...)

  45. Space, Time, and Irreversibility.Gustavo E. Romero - 2017 - MÈTODE Science Studies Journal 7:201-209.
    Scientific philosophy is that which is informed by science. It uses exact tools such as logic and mathematics and provides a framework for scientific activity to solve more general questions about nature, the language we use to describe it, and the knowledge we obtain thanks to it. Many of the scientific philosophy theories can be proven and evaluated using scientific evidence. In this paper, I focus on showing how several classical philosophy topics, such as the nature of space and time (...)

    Time travel and superluminal travel are two of mankind's dreams. They inspire our imagination and provide material for bizarre stories. -/- A work on the subject of time travel and superluminal travel forces us to re-examine our concept of "time". The complexity and the contradictory nature this subject makes it difficult to be more precise about "time". On its deepest subjective side, time is a means of perception, a biological rhythm, a social phenomenon in terms of our collective understanding of (...)

  49. The Unrealities of Time.Baptiste Le Bihan - 2015 - Dialogue 54 (1):25-44.
    Is time flowing? A-theorists say yes, B-theorists say no. But both take time to be real. It means that B-theorists accept that time might be real, even if lacking a property usually ascribed to it. In this paper, I want to ask what are the different properties usually ascribed to time in order to draw the list of different possible kinds of realism and anti-realism about time. As we will see, there are three main kinds of anti-realism. I will claim (...)

    Zur Aufklärung der vielschichtigen Beziehungen zwischen Lebenswelt und Physik diskutiere ich die für die beiden Erfahrungsweisen jeweils typischen Konzeptualisierungen von Zeit. Nach einer Einleitung beginne ich mit der Analyse der subjektiven und objektiven lebensweltlichen Zeitformen. Anschließend erörtere ich im dritten Abschnitt das Verhältnis von lebensweltlichen und physikalischen Elementen der Weltzeit. Vier physikalische Zeitverständnisse stelle ich in ihrer Differenz zur lebensweltlichen Auffassung im vierten Abschnitt dar. Historisch hat sich die generelle Tendenz zur Vergrößerung dieser Differenz fortgesetzt, ohne dass schon Instanzen zur (...)
