Say there is a soul. We inspect a teleportation process, and we find that, just like your body and brain, the soul disappears on the transmitter pad, and an identical soul appears on the receiver. What would this tell you that you don’t already know?
What, in principle, could demonstrate that two souls are in fact the same soul across time?
By “soul” here I mean a carrier for identity across time. A unique verification code of some sort. So that after we conduct a cloning experiment we can check and see that one person has the same code, while the other has a new code. Likewise, after the teleportation we can check and see whether the teleported person has the same code as before.
It really doesn’t seem like our universe works like that, but knowing this doesn’t help much to understand how exactly our reality is working.
What observation could demonstrate that this code indeed corresponded to the metaphysical important sense of continuity across time? What would the difference be between a world where it did or it didn’t?
Consider a simple cloning experiment. You are put to sleep, a clone of you is created, after awakening you are not sure whether you are the original or the clone. Now consider this modification: after the original and the clone awakens they are told their code. And then each of them participate in the next iteration of the same experiment, untill there are 2^n people each of whom has participated in n iterations of experiment.
Before the whole chain of the experiments starts you know your code and that there are 2^n possible paths that your subjective experience can go through this iterated cloning experiment. Only one of these path will be yours in the end. You go through all the chain of the experiments and turns out you have preserved your initial code. Now lets consider two hypothesises: 1) The code does not correspond to your continuity across time; 2) The code does correspond to your continuity across time. Under 1) you’ve experienced a rare event with probability 1/2^n. Under 2) it was the only possibility. Therefore you update in favor of 2).
The original mistake is that feeling of a “carrier for identity across time”—for which upon closer inspection we find no evidence, and which we thus have to let go of. Once you realize that you can explain all we observe and all you feel with merely, at any given time, your current mind, including its memories, and aspirations for the future, but without any further “carrier for identity”, i.e. without any super-material valuable extra soul, there is resolving peace about this question.
With that outlook, do you still plan for tomorrow? From big things like a career, to small things like getting the groceries in. If you do these things just as assiduously after achieving this “resolving peace” as before, it would not seem to have made any difference and was just a philosophical recreation.

Mind, in this discussion about cloning thought experiments I’d find it natural that there are not many currently tangible consequences, even if we did find a satisfying answer to some of the puzzling questions around that topic.
That said, I guess I’m not the only one here with a keen intrinsic interest in understanding the nature of self even absent tangible & direct implications, or if these implications may remain rather subtle at this very moment.
I obviously still care for tomorrow, as is perfectly in line with the theory.
I take you to imply that, under the here emphasized hypothesis about self not being a unified long-term self the way we tend to imagine, one would have to logically conclude sth like: “why care then, even about ‘my’ own future?!”. This is absolutely not implied:
The questions around which we can get “resolving peace” (see context above!) refers to things like: If someone came along proposing to clone/transmit/… you, what to do? We may of course find peace about that question (which I’d say I have for now) without giving up to care about the ‘natural’ successors of ours in standard live.
Note how you can still have particular care for your close kin or so after realizing your preferential care about these is just your personal (or our general cultural) preference w/o meaning you’re “unified” with your close kin in any magical way. It is equally all too natural for me to still keep my specific (and excessive) focus & care on the well-being of my ‘natural’ successors, i.e. on what we traditionally call “my tomorrow’s self”, even if I realize that we have no hint at anything magical (no persistent super-natural self) linking me to it; it’s just my ingrained preference.

The word “just” in the sense used here is always a danger sign. “X is just Y” means “X is Y and is not a certain other thing Z”, but without stating the Z. What is the Z here? What is the thing beyond brute, unanalysed preference, that you are rejecting here? You have to know what it is to be able to reject it with the words “just” and later “magical”, and further on “super-natural”. Why is it your preference? In another comment you express a keen interest in understanding the nature of self, yet there is an aversion here to understanding the sources of your preferences.
It is equally all too natural for me to still keep my specific (and excessive) focus & care on the well-being of my ‘natural’ successors, i.e. on what we traditionally call
Too natural? Excessive focus and care? What we traditionally call? This all sounds to me like you are trying not to know something.
I’m sorry but I find you’re nitpicking on words out of context, rather than to engage with what I mean. Maybe my EN is imperfect but I think not that unreadable:
A)
The word “just” in the sense used here is always a danger sign. “X is just Y” means “X is Y and is not a certain other thing Z”, but without stating the Z.
… ‘just’ might sometimes be used in such abbreviated way, but here, the second part of my very sentence itself readily says what I mean with the ‘just’ (see “w/o meaning you’re …”).
B)
You quoting me: “It is equally all too natural for me to still keep my specific (and excessive) focus & care on the well-being of my ‘natural’ successors, i.e. on what we traditionally call”
You: Too natural? Excessive focus and care? What we traditionally call? This all sounds to me like you are trying not to know something.
Recall, as I wrote in my comment, I try to support “why care [under my stated views], even about ‘my’ own future”. I try to rephrase the sentence you quote, in a paragraph that avoids the 3 elements you criticize. I hope the meaning becomes clear then:
Evolution has ingrained into my mind with a very strong preference to care for the next-period inhabitant(s) X of my body. This deeply ingrained preference to preserve the well-being of X tends to override everything else. So, however much my reflections suggest to me that X is not as unquestionably related to me as I instinctively would have thought before closer examination, I will not be able to give up my commonly observed preferences for doing (mostly) the best for X, in situations where there is no cloning or anything of the like going on.
(you can safely ignore “(and excessive)”. With it, I just meant to casually mention also we tend to be too egoistic; our strong specific focus on (or care for) our own body’s future is not good for the world overall. But this is quite a separate thing.)
I didn’t mean to be nitpicking, and I believe your words have well expressed your thoughts. But I found it striking that you treat preference as a brick wall that cannot be further questioned (or if you do, all you find behind it is “evolution”), while professing the virtue of an examined self.
In our present-day world I am as sure as I need to be that (barring having a stroke in the night) I am going to wake up tomorrow as me, little changed from today. I would find speculations about teleporters much more interesting if such machines actually existed. My preferences are not limited to my likely remaining lifespan, and the fact that I will not be around to have them then does not mean that I cannot have them and act on them now.

This is the most interesting answer I’ve ever gotten to this line of questioning. I will think it over!

Btw, regarding:

The answer that satisfies me is that I’ll wonder about cloning machines and teleporters when someone actually makes one. 😌
