    I'm suggesting it could be that you have one life and experience it multiple times. So each time you experience it, you never remember the previous time, so it feels like the first time. If you remembered the previous experience, it would not be the same life.Devans99

    Again, this simply doesn't make sense. You can't watch a film for the first time numerous times, can you? On your view you can. So much the worse for your view. It doesn't make sense.

    You can live your life once, not numerous times. You can live numerous indistinguishable lives. But living numerous indistinguishable lives is not the same as living the same life again and again. Living the same life again and again would mean watching a film for the first time numerous times - which is obviously impossible.

    Think about 4d spacetime. There is no past/present/future in 4d spacetime. All moments have the same status. So I introduced the moving spotlight idea (not mine) as a way to have eternalism and have a distinction between 'now' and past/present. We can distinguish now from past/present so the concept seems to be a requirement. The moving spotlight moves over Jan 2020 and then X billion years later, it moves over Jan 2020 again.

    It is exactly you who is represented as a pixel on the circle of time and the spotlight comes around many times. So it would be exactly like watching a film for the first time repeatedly.

    This doesn't address my point. Put all the fancy labels you like on things, and talk about spotlights to your heart's content, you're not addressing the point.

    The point is this: on your view, 'now' is also 'future' and 'past'. So, this moment right now, is also future and also past. No good saying that it is just 'presently now', for it is also presently future, and presently past - on your view.

    That's incoherent.

    Not really. Everything would be calibrated to the start/end of time - the Big Bang / Big Crunch. So a moment would have in its future all the moments unto the Big Crunch and in its past all the moments from the Big Bang.

    Besides, I do not see the problem. The grandfather paradox is impossible - nothing can pass though the reset point of time at the Big Bang / Big Crunch.

    All moments of time are alternatively future, present and past. So I do not see your point.

    The proof is actually all intelligent beings must be benevolent:

    1. You are an evil person. You meet a good person. You are punished
    2. You are an evil person. You meet a evil person. You are punished
    3. You are an good person. You meet a evil person. You are punished
    4. You are an good person. You meet a good person. You are rewarded

    This sounds good, but has no basis in reality if one is attempting to prove anything about God. Even if you are defining God as an unknown limited entity, which you do here. It is an example of the thinking of a human intellect. It can only be relevant on the assumption that God is made in our image. Which is clearly naive, because by definition God made our universe, of which we are a small part.

    To illustrate, God may be a being who does not think in a linear, or binary way like we do, but might have a consciousness which is all knowing and understanding simultaneously, with no reasoning going on. God might have real understanding, while we as primitive minds can only ever assemble a one, or two dimensional conception of an artificial construct(our world). So have no real understanding of anything.

    There is a system of thought which is known in mysticism which is analogous to what you are suggesting, but works whatever the unknown entity or God is that one is proposing to encounter. One offers oneself up to any being who is at least as benevolent as ones self. The offer is not made to any being who is less benevolent than oneself. Therefore any being with whom one encounters, through mutual consent, is safe to encounter whatever form they take, because no harm will come of you, because you yourself is sufficiently benevolent, that you would do no harm to any being you encounter, even if they are less benevolent than yourself. Such a system of contemplation is a pre-requisite to any communion with an unknown advanced entity, or God.

    Perhaps I should ask you to define God, or which theological system you are referencing?

    I am saying that our kind of thinking is not up to the job of saying what Gods nature is or isn't. Let me illustrate how God can be both omniscient and limited at the same time. At the end of my last post I mentioned communion. God might be in eternal communion with a near endless number of other Gods, who as a collective are essentially omniscient. So God is not "god fearing", or lacking of any knowledge of all the other Gods out there. On the contrary God might be in eternal communion with all other real beings (remember, I am suggesting that we as we know ourselves are not real, but constructs).

    Anyway another point I was going to make in reference to your argument, was that for real beings there might not be any such thing as a non benevolent being, that might only occur in artificially constructed realities.

    All point [3] says is 'If there is no nth moment there is no nth+1 moment'. In the case of time ending, then there is an nth moment, so argument [3] does not apply to that scenario.Devans99

    You're right my bad

    So the spotlight would have had to start somewhere, no doubt at the Big BangDevans99

    If time is circular then why would the spotlight have started at the big bang? It could have started at any point.

    If time is circular, events must be deterministic, because if they're not they wouldn't repeat given the same conditions, so time wouldn't be circular

    That is about 5 proofs I've given that time has a startDevans99
    I've just addressed a couple of them — Leibnizian sufficient reason and your mathematical induction (and similar) — neither of which work. No use in repeating them I s'pose. I can show you again why they don't work. Here's the latter again:

    1. suppose no definite earliest time, no 1st moment (premise towards reductio ad absurdum)
    2. then there's no 2nd moment, obviously, since it would be the next number following the 1st
    3. if there's no nth moment, then there's no n+1th moment (n ∈ N)
    4. thus
    4.1. there can be no such moments at all, contra 1 :fire: (n)
    4.2. there can be no such numbering of such moments (y)

    Vs 0 proofs you have given that time has no startDevans99
    I'm not aware of any such proof. As mentioned somewhere, it's not a mere logical matter.

    if you remove a previous moment, all subsequent moments become undefinedDevans99
    I take "become undefined" to mean more or less "cannot exist". In the abstract, supposing a (definite) 1st moment = "removing all previous moments", which then, by this ↑ supposition of yours, implies that "all subsequent moments become undefined".

    If time is circular then why would the spotlight have started at the big bang? It could have started at any point.khaled

    It depends on how exactly time works:

    - If time is fully future real all the time, then the spotlight of time could start anywhere as you say. But fully future real is sort of a tough sell

    - So instead I was thinking of a hybrid model between future real and the growing block model of time: The Big Bang is the moment of initial creation. On the first iteration (first circle of time), the future is real but null (so like growing block). Then future is built up - the Big Bang happens, our earth results and later there is a Big Crunch. On the second and subsequent iterations, the future is real and non-null (and repeats exactly as before).

    If time is circular, events must be deterministic, because if they're not they wouldn't repeat given the same conditions, so time wouldn't be circularkhaled

    I'm not sure that determinism is a requirement: each event happens once (is determined once) but it experienced multiple times.

    A couple of more proofs that time has a start:

    Actual infinity is impossible (see https://thephilosophyforum.com/discussion/7379/infinite-bananas/p1) and past infinite time is an example of actual infinity. So time must have a start.

    And...

    1. Assume time had no start
    2. Assume a particle had a collision 5 minutes ago, label that 1
    3. Assume the particle had a collision 10 minutes ago, label that 2
    4. Assume the particle had a collision 20 minutes ago, label that 3
    5. And so on, collision numbers getting higher as we go back in time
    6. How many collisions has the particle had?
    7. It cannot be actually infinite collisions as it is impossible to count to actual infinity
    8. So it must have had every number of collisions
    9. So the particle has counted every possible number in the past
    10. But [9] is impossible, if you count 100 numbers, you are 0% of the way to counting all numbers. If you count a billion numbers, you are 0% of the way there. n/∞=0% so it is not possible that the particle counted all numbers
    11. So the particle must have a finite number of collisions in the past
    12. So time has a start.

    Could the counting eternal alien be on a finite number? No, then he would not be eternal.
    Could the counting eternal alien be on a infinite number? No, impossible to count to infinity.
    So by elimination of all possible numbers, he must be on UNDEFINED.

    He never started counting (a past forever has no start).

    The general rule is 'in order to be X, one has to start X', eg:

    - In order to be counting, one has to start counting
    - In order to be moving, one has to start moving
    - In order to be orbiting, one has to start orbiting
    - In order to be existing, one has to start existing

    Nothing can exist forever in time. Can't get something from nothing, so something must have always existed. Hence time must have a start and something timeless must exist.

    Your argument assumes that time consists of distinct and individual moments. But we experience time as continuous. These two have not been shown to be compatible, so to proceed with your argument you need to demonstrate the real, distinct, individual moments that time consists of, to support your premise. This is the matter which aletheist has brought up.

    If we remove any moment or time interval if you prefer, then all subsequent moments or time intervals become undefined.Devans99
    Since all real moments are indefinite, it is logically impossible to distinguish one from another, let alone "remove" one. We can arbitrarily designate instants to mark off intervals of time with fixed and finite duration, but we cannot "remove" those, either. It straightforwardly begs the question to treat time as if it were isomorphic to the natural numbers, which are discrete and have a first member, thus ruling out the possibility that time is truly continuous and does not have a definite beginning.

    As for the thread title, Charles Sanders Peirce has an interesting take.
    It may be assumed that there are two instants called the limits of all time, the one being Α, the commencement of all time and the other being Ω, the completion of all time. Whether there really are such instants or not we have no obvious means of knowing; nor is it easy to see what "really" in that question means. But it seems to me that if time is to be conceived as forming a collective whole, there either must be such limits or it must return into itself. This is an interesting question. — Peirce, NEM 3:1075, c. 1905
    Real time as a whole either has first and last instants or indeed "must return into itself," but we cannot determine which is the case solely by means of a strictly mathematical "proof."
    You may, for example, say that all evolution began at this instant, which you may call the infinite past, and comes to a close at that other instant, which you may call the infinite future. But all this is quite extrinsic to time itself. Let it be, if you please, that evolutionary time, our section of time, is contained between those limits. Nevertheless, it cannot be denied that time itself, unless it be discontinuous, as we have every reason to suppose it is not, stretches on beyond those limits, infinite though they be, returns into itself, and begins again. — Peirce, RLT 264, 1898
    Mathematical time, conceived as truly continuous, necessarily "returns into itself, and begins again."
    Actual time, in which all events occur, might correspond to only a portion of that hypothetical representation, between initial and final instants. We "reckon" actual time by arbitrarily assigning dates in accordance with the fixed and finite intervals between recurring events, such as the earth's rotation around its axis (one day) and revolution around the sun (one year).
    Observation leads us to suppose that changing things tend toward a state in the immeasurably distant future different from the state of things in the immeasurably distant past ... It is an important, though extrinsic, property of time that no such reckoning brings us round to the same time again. — Peirce, NEM 2:249-250, 1895
    Peirce's own cosmology is not "elliptical" (or "circular"), but "hyperbolic," positing that the states corresponding to the initial and final instants are different from each other as ideal limits, rather than actual events--complete chaos in the infinite past, and complete regularity in the infinite future.
    But at any assignable date in the past, however early, there was already some tendency toward uniformity; and at any assignable date in the future there will be some slight aberrancy from law. — Peirce, CP 1.409, c. 1888

    We cannot even mark off intervals of time by designating instants, because as special relativity indicates such designations would differ depending on your frame of reference. So to use Einstein's example; what you might call "the instant" that the lightning strikes the embankment is different depending on whether you are on the train or whether you are standing on the platform.

    We can't, but we know that an infinite past essentially comes with a moment removed at the start so such a construction is therefore impossible.

    Infinite past time is like a something from nothing - there is no initial state, so no subsequent states - the existence of the present would therefore be like a magic trick.

    Time may run at different rates for different people, but I feel each individual experiences it linearly so it is best represented by a linear series of moments. In SR/GR spacetime has a specific shape to it, so definitely has a temporal starting point (eg the spacetime of the Big Bang and aftermath are visualised as a 3d cone).

    ... we know that an infinite past essentially comes with a moment removed at the start so such a construction is therefore impossible.Devans99
    This is exactly backwards. An infinite past entails that there has never been a moment that was not preceded by another moment, consistent with the continuity of time that we directly perceive in the present. A definite beginning of time entails that there was one moment in the past that was not preceded by another moment, making it a discontinuity.

    Infinite past time is like a something from nothing - there is no initial state, so no subsequent states - the existence of the present would therefore be like a magic trick.Devans99
    Again, this is exactly backwards. Infinite past time entails that there was never nothing, instead always something--namely, time itself. A definite beginning of time entails that something came from nothing, or that something outside of time created it. As I said before, a strictly mathematical "proof" is insufficient to determine which hypothesis--infinite past time or a definite beginning of time--is correct.
