Again, your use of the term "illusion" wants to suggest that it's invalid/not "real". This obsession with validity comes from the assumption that there can only be one 'truly true' truth and that we should seek it because any other concept or perception of truth is "invalid".
We invented clocks to synchronize our interactions with each other and with the environment we live in. You are calling synchronicity, "accuracy". Again suggesting that this determines "validity".
But time is not defined by synchronicity, which is why we experience it differently from each other in the first place. And why we had to invent machines and arbitrary scales of measurement to help us sync up with each other interactively. If anything were to be labeled "invalid" regarding time it's this mechanically imposed, overlay.
I have only used the word “illusion” once….
in a question to determine if you perceive time as such after having quoted your claim …
No one's perception of time is "invalid" because time is a perceptual phenomena. It doesn't exist apart from our perception of it.
The statement “It doesn’t exist apart from our perception of it” can easily be construed as meaning that it’s an illusion, and thus the question in order to clarify your meaning. To determine if YOU meant it’s not “real”.
So, do you believe time is an illusion; that it is not “real”?
When you claim: “We invented clocks to synchronize our interactions with each other and with the environment we live in.”
That’s not quite accurate.
Earlier instruments (sun dials/shadow clocks) accomplished those tasks.
We invented and perfected clocks/watches/chronometers to more precisely and unambiguously measure the passing of time in an objectively reliably, precise and accurate manner.
For example look up John Harrison, who invented the first chronometer after the British Parliament offered financial rewards of up to £20,000 (equivalent to £3.35 million in 2022) in 1714 in order to solve the problem determining longitude on a ship at sea.
In order to determine longitude, one needs a reliably accurate instrument that remains in synchronization with time in Greenwich to a very precise degree.
An error of a few seconds can result in an error of positions of miles.
We invented clocks to synchronize our interactions with each other and with the environment we live in. You are calling synchronicity, "accuracy". Again suggesting that this determines "validity".
“Synchronicity”: (An apparently meaningful coincidence in time of two or more similar events that are not causally related.)
“Synchronization”: ( To occur at the same time or coincide or agree in time.)
(To go on, move, operate, work, etc. at the same rate and exactly together; recur together.)
(To cause to indicate the same time, as on one timepiece to another.)
When you use the word “synchronicity” here, do you mean “synchronization”…wouldn’t that be more to the point?
I am taking it as the meaning you intended would be synonymous with “synchronization” ( To occur at the same time or coincide or agree in time.) ( To go on, move, operate, work, etc. at the same rate and exactly together; recur together) (To cause to indicate the same time, as one timepiece to another).
Would that be correct?
You are calling synchronicity, "accuracy". Again suggesting that this determines "validity".
Assuming you meant “synchronization” as outlined above……
When you have a room with 20 clocks (designated as A-S) all synchronized to UTC (Coordinated Universal Time) and over the course of a week 18 clocks remain in exact synchronization, 1 clock (S) shows a time that is 43 seconds behind the 18 clocks that remain in synchronization, and 1 clock (F) shows a time 22 seconds ahead of the 18 clocks that remain in synchronization.
After another week goes by clock (S) shows 87 seconds behind, and clock (F) shows 44 seconds ahead of the rest of the group of 18 clocks that remain synchronized exactly with UTC.
Clocks (S) and (F) would be considered less accurate (the extent to which a given measurement agrees with the standard value for that measurement).
Would you not agree?
Since
Validity refers to how accurately a method measures what it is intended to measure. High reliability is one indicator that a measurement is valid.
So yes, I’m suggesting that proven, reliable synchronization with a verified standard measurement is indicative of accuracy (the extent to which a measurement agrees with the standard value for measurement) and therefore more valid (sound; just; well-founded).
But time is not defined by synchronicity
Assuming once again the intended meaning here being “synchronization” in lieu of “synchronicity” as described above, you are correct it does not define it, but it is essential to demonstrably accurately, reliably, precisely, and unambiguously, measure the passage of it… which is what we’re talking about here.
Thus leading to the aplicable validity of it.
