I'm talking hypothetically. It refers to a hypothetical state of affairs. Does that make sense? — Purple Pond
How can mere words be about anything? For example, when I say, "the cat is on the mat", I'm talking about the cat being on the mat. The statement is about a state of affairs. — Purple Pond
They're more relaxing, yeah. — fdrake
There is no "lack of motion" in eternalism, so yes I ignore fictitious problems. — Inis
W indicates that the concepts of ethics and aesthetics contain a high degree of blurriness, and that (e.g.) philosophers have a similarly hopeless task of trying to find "definitions that correspond to our concepts". — Luke
It's only indeterminate if you're looking for an overaching time perspective, which is why I brought that up first. — Terrapin Station
Exactly, just as the twin that takes a side trip to some other star and back is not measuring the duration between the two events of departure and return. — noAxioms
Do you agree? — creativesoul
can measure the distance between myself and that tree over there, and get an indeterminate value because one of the measuring tapes takes a path around that other tree to the left over there, and thus measures a different distance. So all measurements are indeterminate in that sense. — noAxioms
This makes no sense to me. If the one reads 500 hours on the nose and the other reads 499 hours, 58 minutes and 30 seconds, then the amount of time between those two is not indefinite, it's a minute and 30 seconds. That's very definite. — Terrapin Station
I think you have a different concept of presentism than the one typically presented on philosophy sites, which might ask when the twins get back together and notice 10 or 20 years elapsed, isn't one of them more correct about how many years actually went by? Presentism would say yes to that, but you seem to say no, since a different amount time passed for each of them, so they're both right about it. — noAxioms
SR just says no preferred folation is locally detectable. It doesn't forbid its existence. — noAxioms
You seem to use 'indeterminate' as 'not absolute'. The word means 'uncalculable', or 'unpredictable', and as Terrapin has been trying to point out, it is quite calculable. These things are just frame dependent, but completely determined given a choice of frames. — noAxioms
This is a feature of your future light cone. That cone, not the present, delimits events which can and cannot be changed.
Similarly, the past light cone, not the present, delimits that about which we can know (events which can have an effect on us, vs those which cannot).
Neither of these fundamental things changes at the boundary of the present, except where the two cones happen to intersect the present. So no fundamental change as described here occurs at the present.
Those light cones are not frame dependent. They are 'determinate' as you put it. — noAxioms
No, it is determinate. This is just arithmetic (the amount of time between t1 and t2 is t2 - t1). Note that to specify times at all is to assume a particular reference frame. Normally we don't have to think about this because we (and most matter in the universe) age at about the same rate (because we move at similarly slow speeds relative to the speed of light). — Andrew M
It is called a preferred reference frame, or at least a preferred foliation (an objective ordering of events). Presentism must assume such a thing, but the existence of a preferred foliation does not necessarily imply the existence of a present (a preferred moment). — noAxioms
Anyway, under the preferred foliation, there is a fixed amount of time between any two moments in time, and frames which do not correspond to this preferred frame are simply not representative of the absolute ordering of events. Hence clocks are all wrong because they're all dilated, some more than others. — noAxioms
In the spacetime model, there is no concept of 'point in time'. — noAxioms
Both the time and the space between any two events is frame dependent (indeterminate), but the combination of the two (the interval) is always the same. — noAxioms
But that's not true. Again, we can know that on the ground, clocks are going to read, say, 500 hours on the nose, while on the space station, clocks read, say, 499-point-whatever (I don't know what the exact difference is--I'd have to research it) hours relative to the 500 hours on the ground.
How is that indeterminate? — Terrapin Station
But time isn't indeterminate in a particular frame of reference. — Terrapin Station
It's just relative--due to factors such as velocity--when you compare different frames of reference. We can predictively calculate those differences to a high degree of precision, which wouldn't make much sense if it were indeterminate. — Terrapin Station
That is two different kinds of referents. It is not two different kinds of referring. — creativesoul
Suppose Alice and Bob are twins. On the day they both turn 20 years old, Bob travels into space at high speed and returns on the day that Alice turns 30 years old (according to Alice's clock on Earth). But Bob is 26 years old (according to the clock on his spaceship) and has only aged 6 years. Less time has elapsed for Bob than for Alice. (Example here.) — Andrew M
- time simply elapsed at a different rate for each clock. — Andrew M
Which means I referred prior to showing. — creativesoul
What I'm questioning here is whether or not pointing alone, and/or showing alone is referring... — creativesoul
And the clue is in the fact that Witty says the seeing-as does not imply seeing differently; — StreetlightX
Witty aims to once again 'de-interiorize' perception - just as he did with the memory-image in §56/57. Just as, in §56/57, the importance of the memory-image had to do with its role in a langauge-game, so too does perception's importance come out in the role it also plays in an economy of use: — StreetlightX
Give me an example of successful reference that uses neither naming practices nor descriptive ones. — creativesoul
Our issue here, as always with you, is a difference in our notions of reference. — creativesoul
In order for successful reference to happen, a speaker must draw an other's attention to the same thing that their attention is already upon... — creativesoul
If the "Present" existed, then the clocks would read the same. — Inis
How about doing a simple time dilation experiment? Synchronise atomic clocks, and take one on a flight around the world. When the clocks are reunited, they no longer agree on the time. How is that possible under presentism? — Inis
I am getting at the idea that an idea of you is more real than the material you that is talking to me right now, do you follow me? The material you is a smartphone to me. All I know of you is your post. Going back to Plato's cave, perhaps you are a human that could track me down and show me you are not a bot, and my reality of you would change, and I would not "hold the idea" that you were just my phone any longer, until then-- and perhaps after if I chose to be an ass about it :wink: --how can I or you know which is the truth? How do you know you are not just an app in my smartphone or vice versa? In essence I understand Plato's argument to say that it is irrelevant-- you are what you convey. — Carmaris19
I’m saying I don’t even need the word “different” to understand relational dissimilarities; it’s just an instance where language mitigates confusion. When I’m working stuff out in my head “difference” is never brought to my attention, even while I’m busy cognizing relative judgements. Still, in a dialogue, the word “different” and it’s variations is used in order to show the participants understand there is in fact some relational disparity between them. — Mww
AJJ constructed his syllogism based on the definitions intrinsic to a favored discipline, and even if the form of the logical argument is valid in the holding to its definitions, the premises are not known to be true, which makes the conclusion unsound (the Universe exists necessarily because a timeless eternal thing created it).
TS, on the other hand, has constructed a logically valid syllogism where the major premise is indeed true, and from which the conclusion is sound (the Universe exists necessarily because we’re in it). — Mww
You say (pg15) logic is what makes this timeless eternal thing necessary and if one skips the logic, the principle of necessity is negated in both A and B. I disagree, insofar as it is merely the definitions grounding the logical argument A, re: “posited to exist timelessly and eternally”, which make the thing ipso facto necessary, and that is henceforth incorporated into the argument, and in B it is the absolute impossibility otherwise which grounds the principle of necessity. — Mww
See the.......er.....difference? — Mww
