Ok, I’ve just got time for a few words right now, I’ll try to elaborate more next time…
The main reason for my drawing attention to and asking you (generic you) to choose between models #2 and #3 (as described in post #81) is because I believe those two are too easily conflated, and have been at some level, during our discussions—sort of like being wave-like some times and particle-like other times. Pitting model #1 against an elusive model #3/#2 hybrid is an act of futility…or, at least difficult to do. Eliminating one of those puts constraints on the other, making for an easier comparison to #1.
Apparently, the consensus of our short list of responders so far is for model #3 (i.e. choosing “Copy” to live in the thought experiment on post #78) and rejecting model #2 (i.e. “it doesn’t matter to me one way or the other"). Therefore, we may conclude that model #3 adherents believe a real vested interest exists between “You, T-0” and “You, t-10”; and between “You, T-0” and “Copy”.
Model #1 vs. Model #3
The first step is to determine whether or not both models are at least theoretically possible, and in compliance with materialism (which we will assume is the correct philosophy). If one is not possible, the other wins by default. If neither is possible, we need to enlist an alternate model. If both are possible, only then must we proceed to the next step, Occam’s razor. I believe #1 wins on both accounts, being possible and more parsimonious, therefore more probable.
I believe #3 is not possible, because there’s a built-in paradox in the system (ultimately the result of conflating #2 and #3). If I fail to persuade you of that, then, we may need to get back in the ring and whip out our razors.
A Case for Model #1:
Let’s describe #1 in a little more detail, then figure out whether it’s theoretically possible. If it isn’t, #3 wins by default. This model says that there is a difference between “You, T-10” and “Copy” and it is with regard to their respective vested interest relationship with “You, T-0”. As far as this relationship is concerned (and only this relationship…we realize all three diverge from each other over time with regard to accumulated memories): “You, T-0” = “You, T-10” but, “You, T-0” ≠ “Copy” and therefore “You, T-10 ≠ “Copy”
There’s only one allowable VI pathway in the original you in this model (from the original you’s perspective) and that resides in your original brain forward and backward in time. If a copy of you is possible at all, then it must have its own unique VI in its own brain from the time of its creation on.
Here is my graphic interpretation of successive instances of accumulating memories in your brain with underlying supervienience (an overlying aura would look better, but I don’t know how to over-score characters):
a b c d e f g h I j k l m n o p q r s t u v w x y z
The single, unbroken line indicates that, even though the supervening “aura” of awareness created by your brain is merely an illusion, the perceived feeling of continuity is real (i.e. there is a real VI continuum into the future). However, the trade off is that it can’t split. If the real VI line exists, but can’t split, where does it go if it has only one place to go?: into a potential copy of itself, or does it remain in the original brain? (hint: it rhymes with drain).
Simple enough, but is this possible? How can there be any difference between any two minds, if their fundamental particle configuration and arrangement is exactly the same, particularly at the point before divergence commences? This seems to violate a major tenet of materialism.
Our physicalist* friends say this is only possible if there is some type of physical permanence that exists in the brain, for the duration of conscious-life, which can somehow bind self awareness to this unique physical continuum (do I have this correct, physicalists?)…converting, I suppose, a non-local event into a local event.
*( I don’t wish to separate myself from physicalists, I’m probably one myself, I just haven’t studied the manual and taken the membership exam, yet).
Is there any type of physical continuum present in the brain that may serve as a candidate for this unique VI pathway existence? Yes indeed, we’ve linked up-thread to cites noting that CNS neurons don’t regenerate or replace (cellular level physical continuum) and that particular occipital-cortex neurons atoms don’t turn over (atomic level continuum). So, continuity exists in the very place we need it to exist (the brain), for as long as we need it to exist (lifespan of active mind), to make consciousness a local event. And, to top it off, with regard to biology, this type of life-long continuity is rare. Coincidence?
(SentientMeat: “I’m happy to go with Frisen’s suggestion that this exception evolved because the configuration must remain more stable than the configuration of other cells” Yes, but for what reason do they need to remain more stable?)
Why would evolution select for non-regenerating neurons if the only result is consciousness? Maybe self awareness makes you horny? Perhaps it’s a chicken and the egg kind of thing wherein the neurons evolved that way for some unrelated reason, but consciousness didn’t develop until they got to that point.
Personally, I think consciousness as a local event is most likely due to either the aforementioned cellular or atomic continuum, but I think there is a third possibility: Since the original spark of conscious “current” begins (in the third trimester) from neural circuitry containing specific sub-atomic particles in space-time, this alone may provide and serve as an “id branding” template, making the resultant current a unique entity. And, as long as the current (the process of self awareness) remains intact and viable from that point on, there’s no reason it can’t remain a local event over time, even if physical continuity breaks down (this has interesting implications).
A Case Against #3
In this model you can imagine each successive instant as a freeze-frame particle configuration and arrangement referencing an accumulation of memories mapped from the previous instant. Adding its own memory configuration in real time, this is then referenced and changed in the next instant, on through time (is this a valid materialistic interpretation?) But, the way I see it, in the reality of this model, nothing is really being passed on as a continuum, memory wise, (like a wave, for instance) from one instance to the next, forward or backward in time. Each instant is more like a self-contained, discreet particle, or capsule of memories as represented by a particular configuration and arrangement of fundamental particles. One instant does not really need the one before or the one after in order to exist as a memory bank capsule, does it? Each freeze-frame instant of particle configuration and arrangement corresponding to a particular bank of memories may exist as a self sufficient entity, with no dependency or interest in any other particle configuration and arrangement. This is the main reason, in the # 2, #3…and maybe even #1 model world view, that memories may theoretically, at least, be able to split off, or be duplicated into multiple Copies. If this was a real hard-wired continuum, it couldn’t really branch, could it?
So far so good. With respect to memories, all three models may (or may not) follow the same mechanics. If this was all there was to it, we could have any number of copies made…of course, they would all be zombies! (Alright, I said I wasn’t going to bring zombies up again, but you needed a little scare to keep you from nodding off).
But, there is something else going on, another layer either acting with, or as one, with these memory frames. This is the supervenience trick of your brain making it appear to come “alive”, to be self aware. This is really the nuts and bolts of your consciousness; it’s not the memories per say, but the illusion your brain creates referencing these memories. This is what we really need to analyze in more detail. I don’t believe anyone can rightfully claim to know exactly how the process works; does it work as one with memories, or is it simply very closely associated with them. If it works as one with the memories, then it should follow the same rules. Here is my interpretation and representation of the memory/supervenience interface, over time, for Model #3:
a b c d e f g h I j k l m n o p q r s t u v w x y z
------------------ \I j k l m n o p q r s t u v w x y z
So we have a series of instances of particle configurations and arrangements referencing memories, each being self-contained and independent. Reassemble this exact configuration and arrangement of memory mapped particles anywhere in the Universe, and they will be the same. It’s a non-local event. If this alone was consciousness, we must conclude that one memory instant has no vested interest in any other one, correct?
But, the supervening aura attached to these discrete packets of memories feels continuous. I feel like I have a real vested interest in the future me and that the past instances of me had an invested interest in me. Can this be real, or, is it merely a false delusion created by your benevolent mind in order to keep you sane?
In this model, memories and the supervening “aura” of self awareness may be thought of as the same thing, correct? So, for the sake of simplicity let’s do away with the time factor and also say there are only 10 particles configured and arranged in a particular way corresponding to the sum total of my consciousness at a particular point in time. This little freeze frame of consciousness should be able to be duplicated anywhere. It need not reference any other set of particles to exist. It’s independent and has no real VI. If you could experience the supervening “aura” of self awareness at this instant, what would it feel like? It would feel like you had a future and it would feel like you had a past. That is the false delusion your brain worked into the machine, right? But, does this instant of self awareness have a real future or a real past? No, there was nothing there before or after. Nothing at all. Memories = awareness=No continuity=No real VI
So, who lives, you or your rich copy? The logical answer is, “it doesn’t matter to me one way or the other”…But, that’s a model #2 answer, the one you threw out.
And, here is where I think the conflating #2 and #3 problem comes in. The real graphic representative of model #3 looks like this:
a b c d e f g h I j k l m n o p q r s t u v w x y z
------------------\I j k l m n o p q r s t u v w x y z
But, this isn’t logical, because it implies a branching, or splitting, of a hard wired local event. This would involve literally being in two places at one time, in my opinion, and therefore, is a paradox.
I must confess, the real reason for my posting this is that I’m concerned that some of you model #2 or #3 believers may make a very regrettable choice one day, and I’d like to talk you out of it. When you reach the logical conclusion that extrapolating your model further means that your Copy is essentially no different than, well, anybody…or anything else that is not you, you may get confused and take a gamble that you shouldn’t: if someone offers to give, say, a duck $1-million dollars if you shoot yourself in the head, please think twice before planning an expensive vacation in some exotic pond).
(Heed this advice: Even if it walks like you and quacks like you, it’s a duck).
Summary:
Model #1 Assumes only 1 vested interest pathway is allowed per individual and it is a real pathway, not imaginary. It may exist as a local event expressed over time because it has physical continuity of some sort. If copies of the individual are possible at all, then they must have a unique VI pathway that begins at the time of their creation and progresses forward in time. VI = Real Local Event
Model #3: Assumes multiple vested interest pathways are allowed per individual, but they cannot be real pathways, only the illusion of continuity exists. As such this is nonlocal and no physical continuity is needed. Each instant a “new” you is created and the “old” you no longer exists. You and any copies of you have no real future. In the next instant, you and your copies believe you had a future in them and that they have a future in the next generation, but they don’t. VI = Illusionary Non Local Event
Model #2: Assumes multiple VI pathways are allowed per individual and they are real pathways, not imaginary. As a non local event, no physical continuity is needed. Action at a distance is allowed and may be expressed as a neural network of transcendent consciousness–some bastardized version of the One Mind Theory, perhaps.
Bonus: Something else to consider for those of you who believe you have a future in your copy. What happens if your copy is made from a map of your mind the way it was 10 minutes ago? Can you still have a future (a real vested interest) in something that was only briefly you in the past?
Conclusion:
You may choose the universe where you can look forward to vacationing in St. Croix next month, firm in the believe that it will really be you drinking mai tai’s on the beach; or the universe where it’s logical to shoot yourself in the head if you see a rich duck waddle by; or the universe that allows, say, an infinite number of SentientMeat-heads to array themselves into a neural network of shared consciousnesses, with the ability to perceive your wife behind closed doors as she undresses. 
Now, which model did you choose, again?
