My answer: the past exists, to the extent that the past is embodied in the present. A baby in the past is embodied in an adult in the present, since the adult causally flowed from the baby. But a past event or object which is embodied by nothing in the present, for instance, a butterfly flapping it's wings once 10000 years ago, no longer exists.

Similarly, future objects and events exist to the extent that they are embodied by present antecedents. For instance, a completed sculpture is embodied by a work in progress, but in a fuzzy manner, to the extent that the completed work can still take many forms. But future events and objects which have no antecedents yet, for instance the bar code number on a receipt given to a raven in a far future corvid civilization, does not yet exist in any sense.

Yes, it does, since you are talking about it.

You are asking the wrong question. You might usefully ask what such-and-such is, or how we use the term "such-and-such".

Here's an interesting quote from Carnap:

"Einstein said the problem of the Now worried him seriously. He explained that the experience of the Now means something special for man, something essentially different from the past and the future, but that this important difference does not and cannot occur within physics. That this experience cannot be grasped by science seemed to him a matter of painful but inevitable resignation. So he concluded 'that there is something essential about the Now which is just outside the realm of science.' "

Reply to Tate Einstein seems to answer that the past and future exist as much as the present. If we grant this, then there is nothing mysterious about a specialness to "now" that cannot be explained by science. It is simply an illusion. After all, every single "now" has this apparent specialness.

"You couldn't have it if you did want it," the Queen said. "The rule is, jam to-morrow and jam yesterday – but never jam to-day."
"It must come sometimes to 'jam to-day'," Alice objected.
"No, it can't," said the Queen. "It's jam every other day: to-day isn't any other day, you know."
"I don't understand you," said Alice. "It's dreadfully confusing!"

I think it's a perfectly good question.

Our experience seems to suggest to many that there is something special, something unique about the present moment, about now, and it is tempting to think that the universe is continuously changing from one instantaneous state into another and exists only as it is in such an instantaneous state.

There are, I understand, weighty arguments against such a view, but it is how we seem to experience things.

I'll reconstruct Parmenides' argument as best as I can.

1. Becoming and Unbecoming are impossible because we can't get an x from what x is not and neither can what x is not get us to an x.

Ergo

2. The past did exist and so it can't not exist. It still exists.

3. The future can't come into existence, but we're traveling into the future as I write this and so the future too exists.

The long and short of it

1. The past, present, and future ALL exist.

On the one hand this is just an issue of grammar. Things in the past existed, things in the present exist, and things in the future will exist.

On the other hand if "yesterday's rock", "today's rock", and "tomorrow's rock" refer to the same object, and if that object exists, then yesterday's rock exists and tomorrow's rock exists.

Perhaps a more relevant question would be "does the rock exist with the properties it had in the past and/or will have in the future", although I think the remark above regarding the grammar should answer that.

Obviously not.

To say a thing exists, logically references a given, present, temporal domain. The minutia of immediate past or future time being irrelevant, insofar as “present” specifically denotes the time of the saying, and only by association, the thing as subject of it.

Assuming “this rock” and “the rock” are in all ways identical.....

......yesterday I could have said this rock exists, but in the given temporal domain, I can only say this rock exist-ed yesterday, because I can prove that it did, which says something about this rock but does not say the same thing, and.....

.......it follows, under the same conditions, that I can only say this rock may exist tomorrow, because I cannot prove it does or does not, which is also saying something, but not the same something, about this rock.

Easy-peasey.

But says not a damn thing about whether past and future exist. The thread title and the OP have no relation to each other.

Things in the past existed, things in the present exist, and things in the future will exist.


Or, e.g. for physics, some existing things are spatio-temporal regions wholly earlier than your present point of view, some temporally overlap that point of view, and some are wholly later.

Quoting Michael
On the other hand if "yesterday's rock", "today's rock", and "tomorrow's rock" refer to the same object [or region of space-time], and if that object [or region not only] exists [but also temporally overlaps your p.o.v.], then yesterday's rock [not only] exists [but also overlaps] and tomorrow's rock [not only] exists [but also overlaps].


Yes, but any temporal slice of the region wholly earlier than today exists, and so does any temporal slice wholly later.

As per the theory of relativity, there is no one NOW, there are as many of 'em as there are moments, each to be experienced from particular frames of reference.

Consider a loaf of unsliced bread (o, the horror, the horror) as the block universe, a corollary of relativity; each slice is a NOW and you can slice the loaf in any way you wish - if you cut the bread at any angle other than 90[sub]o[/sub] relative to the length of the bread, you might see a slice of the past or the future relative to the base NOW which is at 90[sup]o[/sup] to the length of the bread , that would be your NOW.

In a sense, yes, though I'm not sure it helps with the question at hand.

i think we have three options:
(1) Tensed language centered on our notional now (most common);
(2) Untensed language with "timestamps" or times as parameters (common among scientists and not too uncommon among philosophers);
(3) Tensed language centered on some other time than our notional now (pretty uncommon except for the historical present -- the option you asked about).

You can, to some degree, use these three strategies interchangeably and just translate among them. I think they aren't entirely equivalent though, and it shows up not in the content of propositions but in our attitudes toward them. We do not remember the future, for instance, under any scheme. And speaking yesterday of the rock as it is today was future-tense speculation, but for us, looking at it in the present, it's merely fact. I think there's more to all that, but again I'm not sure it helps at all.

#1 gives us an image of time as something digital, or pulsing. Existence only applies to the present. The past is gone and future is imaginary.

#2 if scientific, time is affected by gravity, or maybe it's an aspect of gravity. There is no universal Now. The content of now, in terms of events, is relative to the observer. I think I have that right.

Quoting SEP article on Time
According to presentism, if we were to make an accurate list of all the things that exist...there would be not a single merely past or merely future object on the list. Thus, you and the Taj Mahal would be on the list, but neither Socrates nor any future Martian outposts would be included. (Assuming, that is, both (i) that each person is identical to his or her body, and (ii) that Socrates’s body ceased to be present—thereby going out of existence, according to presentism—shortly after he died. Those who reject the first of these assumptions should simply replace the examples in this article involving allegedly non-present people with appropriate examples involving the non-present bodies of those people.) And it is not just Socrates and future Martian outposts, either—the same goes for any other putative object that lacks the property of being present. No such objects exist, according to presentism.

There are different ways to oppose presentism—that is, to defend the view that at least some non-present objects exist. One version of non-presentism is eternalism, which says that objects from both the past and the future exist. According to eternalism, non-present objects like Socrates and future Martian outposts exist now, even though they are not currently present. We may not be able to see them at the moment, on this view, and they may not be in the same space-time vicinity that we find ourselves in right now, but they should nevertheless be on the list of all existing things.

It might be objected that there is something odd about attributing to a non-presentist the claim that Socrates exists now, since there is a sense in which that claim is clearly false. In order to forestall this objection, let us distinguish between two senses of “x exists now”. In one sense, which we can call the temporal location sense, this expression is synonymous with “x is present”. The non-presentist will admit that, in the temporal location sense of “x exists now”, it is true that no non-present objects exist now. But in the other sense of “x exists now”, which we can call the ontological sense, to say that “x exists now” is just to say that x is now in the domain of our most unrestricted quantifiers. Using the ontological sense of “exists”, we can talk about something existing in a perfectly general sense, without presupposing anything about its temporal location. When we attribute to non-presentists the claim that non-present objects like Socrates exist right now, we commit non-presentists only to the claim that these non-present objects exist now in the ontological sense (the one involving the most unrestricted quantifiers).

One can certainly say something about the rock in the present, the present being defined as what is happening right now, at this moment, while I am looking, and maybe feeling, the rock. But I cannot say anything with certainty about that rock when the moment passes and the event is something in the past. Much less can I say anything with certainty about what will happen to this rock in the future.

But I don't think that this example reflects your topic: Do the past and future exist?

Anyway, my answer to that question is "No, they don't". Past refers to something that existed or has happened and passed, so it doesn't exist anymore. Future refers to something that has not happened yet, so of course, it doesn’t exist either.

The future and past are very real. The future, as what will be, is a world of possibility. The past, as what has been, is the world of actuality. The difficult part to understand is the present, the world of change. This is when possibility becomes actual. We know the present is real because change is real, and change only occurs at the present.

Reply to Metaphysician Undercover
I have a somewhat similar view. I believe the past and future is real, but only by virtue of the present.

The past is not like a museum hall frozen in time. The past is both the progenitor and the imprint on the present. The bite wound on my finger is real, and the event that caused it is real, as it caused and imprinted the present state of my finger, and my memory of it. But as the scar and my memory fades, so does the bite event. In 100 years, the event will have passed from existence.

Similarly, the future is the set of open possibilities which can be arrived at from the present. A future event is real to the extent that it is the likely possibility or range of possibilities. The future event of me sitting in this chair 10 seconds from my typing this sentence is quite real, most paths from the present lead to it. But it is not quite as real as my present state of sitting. Where I will be at this time of day in June is largely undetermined and so has not emerged as real yet. The first thought of my day 20 years from now is barely real yet at all, since it is almost totally unconstrained from this point.

Tzeentch September 25, 2022 at 18:38 #742347
I think the fact that events in the past affect the present, and the events in the present affect the future, should not be confused with either being real.

Neither past nor future is real. If they are real, then where are they?

According to theory of relativity, time is a special kind of space. So you could say that the rock of yesterday or tomorrow exists in that space, just in a different location. However we cannot interact with objects in that space like we can with objects in the usual space, so we use past and future tenses of verbs when talking about past and future.
hypericin September 25, 2022 at 18:46 #742350
Moreover, even if the implication of relativity is true, that past and future are coequally real with the present, doesn't mean that they are real for us.

Similarly, from the god's eye view, there might be billions of other universes. But their events do not intersect ours, at all, and so from our view, they are not real.

According to theory of relativity, time is a special kind of space. So you could say that the rock of yesterday or tomorrow exists in that space, just in a different location.


So then the passage of time is an illusion, we experience every moment "simultaneously".

But we are "flatland" creatures living in a 4d universe confined to a 3d space, which, from our perspective, is drifting through the 4th dimension. Is 3d space real to flatlanders? I would say, only to the extent that it impinges on their 2d world. Events in 3d space which do not intersect their 2d world do not exist for the flatlanders.

Reply to hypericin You are choosing to think in antirealist terms. The consequence is rejecting bivalence and moving to non-classical logic. Hence your question, in the OP.

Perhaps you think you are describing how things are. But what you are doing is choosing between various ways of talking about how things are. I suspect you suppose yourself to have made a metaphysical discovery, that events in the past and future do not have a truth value. You haven't.

In the way of speaking you have chosen, there may be no truths about past and future events. Now it seems to me that this forms a reductio, and a good reason for rejecting antirealism; that it is better to choose a way of talking that permits events in the past to be true or false.

All this to return to the answer to your question: It is true that the rock existed yesterday.

The one in my yard, that Wife wants moved over to the new garden bed. It's been under the tree for years. This is how we do, and also how we ought, talk about rocks.

1. I do not rejected classical logic. But it is not a complete tool, much as Newtonian physics is an accurate but incomplete description. The world seen through the lens of language is simply not bivalent.
2. Rejecting bivalence is not antirealism., in fact quite the opposite. It is rejecting a distortion that prevents a faithful rendering of what is real.
3. That truth or falsity depends merely on the manner in which we speak of seems decidedly antirealist to me.
4. You quoted a discussion where I was defending the reality of the past and future. Its just that this reality, as most things, is not 0 or 1.


Banno September 25, 2022 at 23:01 #742410

If you take reality to be mind independent then you commit to there being statements that are neither true nor false - like that the rock existed yesterday. Hence you drop classical logic in favour of some form of paraconsistent logic. While rejecting bivalence need not lead to antirealism, antirealism does lead to rejecting bivalence.

Seems to me you are not happy with the consequences of reality being mind independent. Might be time to reconsider it.

To approach the issue of what reality is/isn't on the basis of mind dependence/independence is, as you can see, a dead end. It seems impossible to tell which is true i.e. the truth is beyond our reach. We can argue though and we are doing exactly that. Personally, I'd propose a motion to change the definitions of real and unreal, to ones that we can actually use to decide questions on whether something is real or not.

Absolutely not.

This is just another way of saying, mind independent. Real/unreal is a conceptual divide which separates that which exists independently of our thoughts of it from that which is our thoughts of it.

True/false is a different divide, which categorizes statements, not existents.

Maybe not in classical logic, but perhaps classical logic doesn't really fit with ordinary language, hence the development of free logic which makes for claims like "God does not exist" possible, and which some of us accept as true.

Or if you want to continue with classical logic then consider what I said here:

That fairies exist is that ?xFx, where Fx means "x is a fairy". If ¬?xFx then fairies do not exist. Some x is my nose but no x is a fairy, therefore my nose exists but fairies don't.

Only insofar as our favourite logic treats it with a special predicate (ish) called a quantifier.

?x T(x) ? R(x)

But in other words,

An x exists such that x is this and x rocks.

Hmm, how about a rockifier?

?x T(x) ? E(x)

An x rocks such that x is this and x exists.

Obviously this would be silly. But the utility of the canonical expression is in requiring an upfront commitment as to the perfectly sensible question whether or not such an x exists.

The distinction between "real" and "unreal" is the distinction between mind independence and mind dependence.


Can you talk about anything at all, that isn’t dependent on the thought of it?

How can anything at all be mind independent, when mind is that which determines what independence is? How can anything be said to be mind independent if the mind has already thought of it?

Just to assert a distinction of anything presupposes a necessary relation which cannot be given from the assertion itself. Even to merely perceive a difference presupposes that which recognizes that there is one, whether entailment of what the difference is occurs or not.

The distinction between the real and the unreal is given merely from the principle of complementarity a priori, but the principle itself is mind dependent. Whatever is real is not unreal, and whatever is unreal is not real. The relation between real and unreal needs to be distinguished long before the relation of either one to its dependence on the mind. Oooooo.....the irony.

If thoughts are real, then everything thought about must be as real as the thought of it, insofar as an empty thought is a contradiction. But the real in thought is never sufficient for the empirical existence of its object in reality. Hence, the thought of the rock of yesterday is a thought just as real as the thought of this rock today, but the existence of either rock is not given by mere thoughts about it.

The validity of things real in thought is a determination of logical reason a priori, and is called a cognition (of); the proof of the reality of the things real in thought, is a determination of practical reason a posteriori, and is called experience (of).

Perhaps now it is clear the original argument is grammatically flawed, insofar far as the existence of “this rock” in a particular time and place, is regulated by its mode of reason, but the existence of “the rock”, which is not necessarily “this rock” but merely signifies any rock in general, of arbitrary past or future time and place, is regulated by its mode of reason. It is therefore unjustifiable to say the same thing about those by which the determinations of each depends on non-congruent modes.
