If I wasn't able to perceive space and time, I wouldn't be able to perceive that the truck was moving straight towards me. It would appear stationary and not presenting an immediate danger. — RussellA
Unfortunately, when going to the dentist, it is my mind that perceives the pain of the cold water on a sensitive tooth. If only it was just my unconscious senses that perceived the pain. — RussellA
However, in your latest post, you refer to the present time as "the temporal position of the sentient being" and "the human perspective" of one individual. — Luke
Therefore, no, you did not explain this. You simply changed your definition of "the present" to suit your argument, and once again did not address mine. — Luke
Disputes over when, or how long, the present time is are irrelevant. Once agreement is reached (or context understood) on that matter, then past and future are determined relative to that. — Luke
No, the present needn't be reduced to a non-dimensional point in time, hence my 1000 years example. You've also given examples of the present time being 2023 or July 8. Once established, the past and future are determined relative to that. — Luke
That people might bicker over the "real" duration of the present is irrelevant. — Luke
If we agree to refer to the current millennium as "the present time" then what comes before the current millennium is the past and what comes after the current millennium is the future, wIthout overlap. Your assertion is therefore refuted. — Luke
Why must it be "reduced to a mathematical point" in order to be "agreeable and reasonable"? You clearly don't agree with it or find it reasonable. — Luke
You are repeating your error of conflating "before" with "past" and "after" with "future". These are not interchangeable terms. If before and after are inside the now, it does not follow that past and future are inside the now, because past and future are determined relative to now. — Luke
Nonsense. Past and future are determined relative to the present. The present is not divisible into past and future, otherwise it would not be the present. — Luke
No part of the present can be in the past because if it were then it would no longer be in the present, and no part of the future can be in the present because if it were then it would no longer be in the future. Likewise, no part of the past can be in the present because if it were then it would not yet be in the past, and no part of the present can be in the future because if it were then it would not yet be in the present. — Luke
The present could be a dimensionless mathematical point or it could be 1,000 years long and, either way, it would still not overlap the past or future. The past is before the present and the future is after the present. — Luke
This is not part of the measurement... — Luke
But, as I understand it, while numbers tend to get grounded in quite abstruse work within set theory that there is less general confidence in, they can also be grounded using category theory. Barry Mazur has some relatively approachable stuff on this, although I certainly don't get all of it.
Timelessness remains either way, mathematics is eternal, not involved in becoming— in most takes at least. This, I think, may be a problem. Mazur had an article on time in mathematics but it didn't go that deep. But I recently discovered Gisin's work on intuitionist mathematics in physics, and that is quite interesting and sort of bound up with the philosophy of time. The Nature article seems stuck behind a paywall, but there is this Quanta article and one on arXiv.

You can forget about mathematical "points". The upshot is that there is no overlap between them; no part of the past or the future "inside" the present. — Luke
When have the conventional meanings of "past", "present" and "future" been "employed for the purpose of measurement"? — Luke
You have changed the meanings of "past", "present" and "future" to try and accommodate relativity? — Luke
Right, so past and future come before and after the present, respectively. In fact, that's what these words are typically used to mean. — Luke
And my argument has been that if you want to place the past and the future within the present time, then you need another present time inside that, that these past and future times actually come before and after. The words create the distinction. You are misusing these words. — Luke
Why do they need to be within the present? — Luke
Okay. But the past is not before the present and the future is not after the present in this example (per your second premise). Of course you will say that some of it is, but then you will need another present which completely is. That's what coming before and after means. — Luke
No, the meaning of the words requires those arbitrary points. — Luke
Are you saying that everyone uses the words "past", "present" and "future" incorrectly? — Luke
Since we can think about the past or the future in the present, then those times are present? — Luke
If you make a distinction between these, then what is it? — Luke
As a reminder, (A) represents past and future times that are external to the present time (A), whereas (B) represents past and future times that are internal to the present time (A); of which the present time (A) consists. Except you later reclaimed (A) times but with imprecise boundaries. However, I note that I never mentioned anything about sharp or imprecise boundaries with regard to (A) times (in the post where I first referred to (A) and (B) times). — Luke
You designed it that way? — Luke
Once again: If the present time (A) consists of both past (B) and future (B) times, then what are those past (B) and future (B) times relative to? They are in the past and in the future of what? — Luke
If there is no distinction between "past", "present" and "future", then what does each word mean? — Luke
I'm curious about your theory, as to how it is we are communicating with each other. However, I can tell you, that you can't understand much about the answer without a more accurate theory of time than you currently have. I suspect you haven't subjected your theory of time to the many falsifying tests which could be done. Thus you haven't seen the need for a more accurate paradigm. — wonderer1
You are correct that we can't think thoughts without a period of time elapsing but look at the inability to clearly distinguish between past and future that comes with your perspective. Do you think it is your thought processes which determine what is past and what is future? — wonderer1
ou don't acknowledge any duration called "the present" that is distinct from past and future times? — Luke
Well, we have different subjective experiences, and based on my subjective experiences it is not only possible, but extremely valuable to recognize difference in our subjective experiences of a present, and happenings in time in the world. — wonderer1
Another factor in my subjective experience is looking at signals captured by oscilloscopes that represent things at time resolutions down to around a nanosecond. I have very good reasons for thinking events really are happening on extremely small time scales regardless of the fact that my unaided perceptions don't reveal things on such small time scales. — wonderer1
Might it be the case that there is a relevant lack of diversity to the sort of subjective experiences you have had? — wonderer1
Most people use the following terms to refer to three distinct periods of time: — Luke
If 1 and 3 above are determined relative to 2, then 4 and 5 are determined relative to what? That is, 4 and 5 are in the past and in the future of what? — Luke
The answer can only be a second present - Present (B) - that is nested within Present (A). — Luke
Rather than a set of immutable numbers, which seems less defensible today, we can have a set of possible, contextually immutable axioms, which define a vast, perhaps infinite space of systems. The truths in the systems are mutable, because there are different systems, but then there is a sort of fall back, second-order Platonism where the existence of the systems themselves, and relations between them, are immutable. — Count Timothy von Icarus
Do you think it would make sense to distinguish between the nature of our subjective experiences of 'the present' and the nature of time in the larger reality we are a part of? — wonderer1
It seems to me that you and Luke are both right in ways, but this discussion seems a muddled mess due to not making such a distinction. — wonderer1
It is relevant because you are misusing the terms "past" and "future" — Luke
Your use of two different senses for each of these terms indicates your use of two different senses of "the present". — Luke
Points in time are consistent with a duration. A duration is a determinate period of time with beginning and end points. It is your premise that the present consists of a duration. — Luke
Thanks for clarifying. However, there seems to be some hidden premises because I fail to see how you reach the conclusion that "time passes" from these premises alone. — Luke
Also, if we take a closer look, premise 1 states that the present consists of a duration and premise 2 states that a duration consists of before and after parts. This implies that the present consists of before and after parts. This does not imply that those before and after parts are past and future parts, because it is the present which consists of those before and after parts. — Luke
We could add that, relative to the present moment, the past comes before the present moment and the future comes after the present moment, but we are not committed to any conclusion that the before parts of the present are past nor that the after parts of the present are future. The before and after parts are only what the present consists of. — Luke
You are still using two different senses of the present moment. — Luke
However, on the other hand, you also treat the present as some mid-point within the duration, which has some parts before it and some parts after, and you treat these as being past and future. — Luke
You should instead treat what is outside the duration of the present as being past and future, rather than what is inside it on either side of the duration of the present's mid-point. — Luke
The Golden Rule advocates initiating indirect reciprocity, the most powerful cooperation strategy known. Indirect reciprocity has no stated goal - it is a cooperation strategy, not a goal generator. — Mark S
If you define "the present" as the entirety of 2023, then the duration of the present is - the present lasts for - the entirety of 2023, by definition. — Luke
That time passes is presupposed regardless of your argument that the present contains parts of the future and past or not. Your stipulation that the present contains parts of the future and past does not make time pass, logically or otherwise. — Luke
Within both the past and future, there are "before" parts and "after" parts. Does it follow from this that the future is in the past and that the past is in the future? — Luke
By definition, it is the duration of the present, not the duration of the past nor the duration of the future. — Luke
We seem to agree that the present moment is defined by your conscious experience, and it is the duration of your conscious experience that defines the duration of the present moment, and only the present moment. — Luke
Why not? There were many years before 2023 and will be many afterwards. — Luke
Which premises? — Luke
How do they contradict the principle premise? They would need to state that conscious experience occurs in the past and in the future in order to contradict it. To avoid contradiction, we could simply state that conscious experience occurred in the past and will occur in the future. — Luke
We don't, not until the end of the story. — Ludwig V
There's another complication here, (which I was about to trip over at the end of my last paragraph. unenlightened's link between narrative and identity focuses on the stories we tell ourselves. — Ludwig V
I don't know how to articulate the next point properly, so I shall ask questions instead. What ensures that there is a single narrative throughout a biological life? What makes it impossible to live more than one narrative at a time? If the answer to those questions is Nothing, and a narrative defines a self, doesn't it follow that multiple narratives and multiple selves are possible? Apart from our legislation, what makes that conclusion paradoxical? — Ludwig V
I've already provided you with several rebuttals to your argument. You are welcome to address them. You could start with this: — Luke
s a part of your present conscious experience in the past and part in the future? — Luke
How can your present conscious experience be in the future or the past? — Luke
Wouldn't they just be your past and future conscious experiences? — Luke
It is defined by our conscious experience and it is the year 2023, or July 2, or whatever. — Luke
How can there be a duration without start and end points? If there is a duration of some length, then that length must have end points. — Luke
How can the present both be defined by our conscious experience and also be 2023? Is a part of your present conscious experience in the past and part in the future? How can your present conscious experience be in the future or the past? Wouldn't they just be your past and future conscious experiences? Unless you wish to argue that you consciously experience 2023 all at once? — Luke
The point being that the heavy-hitters in philosophy of maths all decry any form of platonism, on the grounds that it verges on a spooky ability to grasp non-physical truths. — Wayfarer
The second sentence does not follow from the first. What is before the present is called "past" and what is after the present is called "future". Therefore, neither the past nor the future are part of the present. — Luke
The present is a duration with start and end points. — Luke
If 2023 is the present, then the past is everything before 2023 and the future is everything after 2023.
If July 2 is the present, then the past is everything before July 2 and the future is everything after July 2.
If this minute is the present, then the past is everything before this minute and the future is everything after this minute. — Luke
There is no part of the past or the future in the present. — Luke
Good. Im glad you did not mean before and after the present. Now all that’s left to explain is how your conclusion follows: — Luke
Why must part of the present be in the future and part of it in the past? — Luke
Before and after what? — Luke
I don't see how the conclusion follows, — Luke
It was this claim about any proposed period of time being "indefinite" and "imprecise" that I was querying and criticising. As you confirm above, this relates only to measurement. There is nothing indefinite or imprecise about a stipulated measure of time, such as a minute. Your introduction of how to "actually apply measurement principles in practise" are not relevant to your statement that "any proposed period of time is indefinite [and] imprecise". A minute is exactly 60 seconds long - no more, no less. — Luke
This makes little sense to me. The present is neither past nor future. I see no reason to accept why it must "consist" of either past or future. — Luke
Are you saying that (e.g.) a minute is an indefinite period of time? Isn't it exactly 60 seconds?
Or are you saying that any measurement of time is indefinite? — Luke
My interest is that I didn't find your argument - that the present moment cannot be an instantaneous point in time - to be very convincing. — Luke
You could make an argument such that if we imagine an instant of time to be like a photograph, and if we consider that the average shutter speed of a typical photograph is 1/60th of a second, then it follows that an actual instant of time requires some duration, no matter how small. — Luke
As (I think) you note, an instantaneous point in time, like a point in space, is a dimensionless concept. However, in reality, if we assume the present to be the time at which we each find ourselves conscious, then a dimensionless point in time with zero duration would seem to be an insufficient "time window" in which to be conscious. A point in time with zero duration is no time at all, and there is nothing to be conscious of in no time at all. Or something like that. — Luke
If you mean a period of time, such as a minute or an hour, then I disagree that these are indefinite periods of time. If you mean any measurement of time, then I suppose there might be at least some imprecision involved with any measurement, but I don't see why it matters. — Luke
But if "an instant" is "not really consistent with reality" as a point in time, then "a minute" is "not really consistent with reality" as a period of time. — Luke
I can stop smoking and then start again, or I can stop smoking and never start again. what's the problem? — unenlightened
A process like identification can begin, and can end, and can begin again. — unenlightened
I have bee quite clear from the beginning that the thread and the topic is all narrative and none other. — unenlightened
It could be argued that the present time is that time while or during your saying of the word "now", and that (at that time) the past precedes this act and the future procedes it. — Luke
Then the same could be said of any period of time - not just an instant - and so all periods of time are "useful ideals" that are not "consistent with reality". — Luke
we must not use language as it is "not really consistent with reality". — Luke
Mostly theists opt for door number 2, and defend revelation as knowledge producing. — Srap Tasmaner
A bullet at any instant is at some point in space but my perception limits me to perceiving it in some region of space in that I cannot tell exactly where it is. Ontologically, the now may be a point in time even if I perceive it as a small region of time. — Art48

Oh yes, it signifies that we have to change all our taboos if we even question one of them, and I am advocating that. — unenlightened

In one person’s reference frame the event is in the present (or past), and in the other person’s reference frame the event is in the future. I find this peculiar. — Michael
Thus far I agree, but in general, the way we 'put clothes on' the body or rather socialise a dress code with legal sanctions, does as a matter of fact serve to raise the level of potential arousal. — unenlightened
But the relativity of simultaneity isn't just about one person seeing something before another person; it's about that thing actually happening for one person before another person. That's what I find peculiar. — Michael
