This paper develops a Fragmentalist theory of Presentism and shows how it can help to develop a interpretation of quantum mechanics. There are several fragmental interpretations of physics. In the interpretation of this paper, each quantum system forms a fragment, and fragment f1 makes a measurement on fragment f2 if and only if f2 makes a corresponding measurement on f1. The main idea is then that each fragment has its own present (or ‘now’) until a mutual quantum measurement—at which time (...) they come (‘become’) to share the same ‘now’. The theory of time developed here will make use of both McTaggart’s A-series (in the form of future-present-past) and B-series (earlier-times to later-times). An example of an application is that a Bell pair of electrons does not take on definite spin values until measurement because the measuring system and the Bell pair do not share the same present (‘now’) until mutual quantum measurement, i.e. until they ‘become’ to share the same A-series. Before that point the ‘now’ of the opposing system is not in the reference system’s fragment. Relativistic no-signaling is preserved within each fragment, which will turn out to be sufficient for the general case. Several issues in the foundations of quantum mechanics are canvassed, including Schrodinger’s cat, the Born rule, modifications to Minkowski space that accommodate both the A-series and the B-series, and entropy.

It is often thought the relativity of simultaneity is inconsistent with presentism. This would be troubling as it conflicts with common sense and—arguably—the empirical data. This note gives a novel fragmentalist-presentist theory that allows for the (non-trivial) relativity of simultaneity. A detailed account of the canonical moving train argument is considered. Alice, standing at the train station, forms her own ontological fragment, in which Bob’s frame of reference, given by the moving train, is modified by the Lorentz transformations. On the (...) other hand, Bob, in the train, forms his own ontological fragment from which Alice’s space and time are modified by the corresponding Lorentz transformations. Each fragment accommodates a unique present moment but does not contain information about the unique present moment of another fragment. This allows for a ‘universal’ present moment that extends throughout space, but only from the perspective of each fragment. The relativity of simultaneity is, as it were, ‘relativised’ to each fragment. This is related to the idea that, roughly speaking, the time of relativity is McTaggart’s (1908) B-series (earlier times to later times) and the time of quantum mechanics is a (fragmentalist) A-series (future/present/past), where these two related series characterize one dimension of time. (shrink)

We motivate and develop a perspectival A-theory of time (future/present/past) and probe its implied interpretation of quantum mechanics. It will emerge that, as a first take, the time of relativity is a B-series (earlier-times to later-times) and the time of quantum mechanics is an A-series. There is philosophical motivation for the idea that mutual quantum measurement happens when and only when the systems’ A-series become one mutual A-series, as in the way qualia work in the Inverted Spectrum. This seems to (...) account for certain quantum phenomena, including that the electrons of a Bell pair do not have definite spins until measurement, as ‘until’ here is a (perspectival) A-series notion. Various issues in the foundations of quantum mechanics are canvassed. (shrink)

Many researchers suppose that the forward direction of time as a consequence of increasing entropy. But the human brain, including the human brain with memories, and life in general, are regarded as pockets of decreasing entropy, so as to accommodate the continual addition of memories and abilities. But then humans and life in general should see time going ‘backward’ in some sense. But we do not. Therefore, time is not entropic in origin. -/- The purpose of this note is to (...) bring attention to this idea. (shrink)

I accept that McTaggart's A-series and B-series are not inter-reducible and that both are needed for a complete temporal description of a physical system. I consider the Wigner's Friend thought experiment. The A-series are associated with each (quantum) system, and relativity is associated with the B-series. I consider temporal evolution through this 'hybrid' time. We may define the rate of temporal flow as 1 B-series second per A-series second.

We start by asking the question of ‘why there is something rather than nothing’ and change this to the question of ‘what are the weakest assumptions for existence’ Eagle [1]. Then we give a kind of Fragmental Perspectivalism. Within this Fragmentalist interpretation of quantum mechanics (each quantum mechanical system forms a fragment) Merriam [2], it turns out McTaggart’s [3] A-series of time (the A-series is future to the present to the past) has a kind of perspectivalism. We then use (...) McTaggart’s A-series and the B-series (the B-series is earlier times to later times) of time to differentiate between how far in the past the big bang was vs. how much earlier than now the big bang was. In one example model, the former goes infinitely far into the past while the latter stays finitely earlier-than. In this model the number of quantum interactions per unit 4-volume goes up to infinity as the big bang is approached from the present epoch. (shrink)

On being released from her black-and-white room into a colorful world it would seem Mary learns something new (the Knowledge Argument). On being released from his B-theory room into an A-theory world it would seem Mark learns something new (the Temporal Knowledge Argument). These thought experiments are parallel to each other and can inform each other.

We give a mathematical definition of the present or 'what is real' and its duration on McTaggart's A-series future/present/past. This is applicable to at least one conception of the block-world, the growing-block, and presentism.

A mechanism for life after death is given.

This article proposes an interpretation of time that incorporates both McTaggart's A-series and his B-series, and tries to cast it in a role that could be useful to physicists. This AB-series allows one, to reconcile special relativity with temporal becoming if the latter is understood as 'ontologically private', which is given a mathematical definition. This allows one to define a unit of becoming, as well as the rates of becoming. This article gives a picture of this interpretation.

We motivate and develop a new theory of time and apply it to a few thought experiments in physics.

There appears to be a temporal analogue to the Knowledge argument. If correct, it could be read as an argument that B-theorism is false: time is not completely described by McTaggart's B-series. We analyse the temporal knowledge argument in terms of Chalmers's 2-dimensional semantics. An adaptation of the most popular response to the Knowledge argument indicates that McTaggart's A-series and B-series have different modes of presentation.

This paper proposes an interpretation of time that incorporates both McTaggart's A-series and his B-series, and attempts to cast it in a way that might be usable by physicists.

This allows one to define a unit of becoming, as well as the rates of becoming. This paper gives a picture of this interpretation and applies a (...) rough outline of the concepts to several test cases. (shrink)

The moving spotlight theory of presentism is well-known (Emery et al. 2020). In this article I will give an unmoving spotlight theory of presentism. It has several components and, I will argue, is more satisfactory than a moving spotlight theory.

This careful note is a very initial foray into the issue of the change in entropy with respect to both McTaggart’s A-series and his B-series. We find a possible solution to the Past Hypothesis problem.

Why is there something rather than nothing? I don't know. But I give an argument that qualia exist *necessarily*. The *possibility* of the existence of red qualia requires actual red qualia to specify what the possibility is a possibility *of*.

We give an apparently new possible explanation for why there might be something rather than nothing—the weakest assumptions coupled with a kind of perspectivalism. Within a Fragmentalist interpretation of quantum mechanics (each quantum mechanics system forms a fragment), McTaggart’s A-series of time has this kind of perspectivalism. We then use the A-series and the B-series to differentiate between how far in the past the big bang was vs. how much earlier than now the big bang was. In one example model, (...) the former goes to infinity while the latter stays finite. This implies the number of quantum interactions per unit 4-volume goes up to infinity as we approach the big bang from the present epoch. (shrink)

Abstract to Equations, Qualia, and Qualations -/- With regard to consciousness, we could write an equation B = black. But it is possible to rewrite this using a quale, namely, B = █. This latter equation might be called a ‘qualation’. It has the same meaning regardless of the physiology that apprehends it. This article argues a whole theory of qualations could be developed. Further, to a Dualist, it could be that a materialist is convinced by materialist arguments involving the (...) first equation, but it is unimaginable how this could ever be for a qualation. In view of the strong association of qualia with McTaggart’s A-series (future/present/past) a few notes on time are included. (shrink)

The purpose of this note is to show how an 'AB-series' interpretation of time, given in a companion paper, leads, surprisingly, directly to the physicists' important AdS5 geometry. This is not a theory of 2 time dimensions. Rather, it is a theory of 1 time dimension that has both B-series and A-series characteristics. -/- To summarize the result, a spacetime in terms of 1. the earlier-to-later aspect of time, and 2. the related future-present-past aspect of time, and 3. 3-d space, (...) automatically gives us AdS_5.

The purpose of this yet-another version of this note is to make another attempt to show how an 'AB-series' interpretation of time, given in a companion paper, leads, surprisingly, apparently, to the signature of the physicists' important AdS^5 geometry. This is not a theory of 2 time dimensions. Rather, it is a theory of 1 time dimension that has both A-series and B-series characteristics.

The motivation comes from the analogy (equivalence?) of the A-series to ontologically private qualia in Dualism. This leads to the proposal that two quantum systems, no matter how small, mutually observe each other when and only when they come to share the same A-series. McTaggart's A-series and B-series can be varied independently so they cannot be the same temporal variable.

This paper proposes an interpretation of time that is an 'A-theory' in that it incorporates both McTaggart's A-series and his B-series. The A-series characteristics are supposed to be 'ontologically private' analogous to qualia in the problem of other minds, such as in the Inverted Spectrum thought experiment, and is given a definition. The main idea is then that the experimenter and the cat do not share the same A-series characteristics, e.g. the same 'now', to some extent. So there is no (...) single time at which the cat gets ascribed different states, one by the experimenter and one by the cat. Also it is proposed one may define an ontologically private 'unit of becoming' that coordinatizes the future/present/past A-series spectrum as well as allow one to calculate rates of becoming with seconds. The latter are taken to measure differences in B-series times. (shrink)

More on McTaggart's AB-series in physics, with integrals.

We define and develop a notion of spacetime that incorporates both McTaggart's A-series and his B-series that is consistent with special relativity. This 'McTaggartian spacetime' or 'AB-spacetime' requires *five* not *4* variables. The interface of two AB-spacetimes from different *ontological perspectives* is quantum mechanical. This note concentrates on the physics and not the philosophy. This is an invitation to contribute to a theory that is a work in progress.

A theory of time was proposed in "A theory of time", an early version of which is on PhilPapers. The idea was that the A-series features of a physical system are ontologically private, and this was given a mathematical definition. Also B-series features are ontologically public. This brief note is a detailed rumination on path-integrals and Schrodinger's Cat, in this theory.

This brief note gives a modest argument that there may be states-of-affairs that require fewer (weaker) assumptions than the assumption or 'default state' of Nothingness. It is meant as an add-on to the paper "Existence and the Big Bang" and to work in concert with several other papers on PhilPapers. This is meant to modestly help the idea that the Big Bang could have happened in the first place.

Non-locality is one of the great mysteries of quantum mechanics (qm). There is a new realist interpretation of qm on the table whose notion of time incorporates both of McTaggart's A-series and B-series. In this philosophically motivated interpretation there is no fact of the matter as to whether the 'now' of one system is the 'now' of another system, until measurement. But this reproduces the idea that the spins of a Bell pair of electrons do not become definite 'until' measurement. (...) And this almost trivially allows for non-locality. (shrink)

We are each entitled to our own opinions, and it’s my opinion that, as of this writing, 8/19/2021, physicists are endlessly confused about both the anthropic argument and the fine-tuning argument. Here is my take on them. The Anthropic argument (which I think works) involves two, not one, data points. The fine-tuning argument fails because ever smaller changes could always be contemplated.

There is a profound difference between asking a 'hard problem' and asking a 'hard problem' that has qualia in the question. There are plausible answers to the former that are nevertheless clearly not answers to the latter. I give a method by which hard problems will be able to be solved, if possible. I speculate on the (possible) causal efficaciousness of consciousness in evolution and in quantum mechanics.

Abstract We motivate and develop an A-theory of time and probe its implied interpretation of quantum mechanics. It will emerge that, as a first take, the time of relativity is a B-series and the time of quantum mechanics is an A-series. There is philosophical motivation for the idea that mutual quantum measurement happens when and only when the systems’ A-series become one mutual A-series. This accounts almost trivially for many quantum phenomena, including that the electrons of a Bell pair do (...) not have definite spins ‘until’ measurement, as ‘until’ here is an A-series notion. This version of the paper is in the process of being re-formatted for submission to a journal. (shrink)

The modest ambition of this short note is to point out a plausible route from a *perspectival ontology* and McTaggart’s *AB-spacetime* to an AdS/CFT correspondence. There are several minor arguments that would need to be filled in for this route to succeed.

The logic of qualia is different than classical logic. We take the first steps in defining it and applying it to the Hard Problem.

Some not quite random thoughts on the logic of qualia.

Relativity is briefly considered. (shrink)

In this short paper I suggest a few properties a good realist interpretation of quantum mechanics ought to have. Then I canvass several interpretations, most of which do not have these properties, and further suggest problems specific to each one. Then I give a reference to a novel interpretation that solves all of these problems.

How can McTaggart's A-series notion of time be incorporated into physics while retaining the B-series notion? It may be the A-series 'now' can be construed as ontologically private. How is that modeled? Could a definition of a combined AB-series entropy help with the Past Hypothesis problem? What if the increase in entropy as a system goes from earlier times to later times is canceled by the decrease in entropy as a system goes from future, to present, to past?

I give three brief scientifically informed arguments that free will is causally efficacious over-and-above the efficaciousness of its physical substrate.

This is an outline of the basic reasoning in the fragmentalist interpretation of presentism and quantum mechanics.

I suggest time flows at 1 B-series second per A-series second.
