I'm going to try this again, because we're all just repeating ourselves endlessly anyway in this never ending nightmare thread:
Jabba, please try to read all of this. This is the Materialist view of the sense of self. It doesn't matter if you agree with it, for your argument to make any sense you need to calculate your probabilities as if this is the case:
- We do experience consciousness, or a sense of self.
- This is caused by our physical brains, by the electrical signals and neurochemistry and all that jazz.
- If our brains are disrupted, so is the sense of self.
- Our sense of self isn't a tangible thing, nor is it a thing at all. It's an emergent property of our brains.
- If you duplicated someone perfectly, that duplicate would also have a sense of self. Since the person was duplicated exactly, both copies would have the same thoughts, feelings, and personality.
- Our sense of self goes away every night when we get some good sleep. By most reasonable definitions it's just gone. When we wake up we once again have a sense of self.
- Likewise, people have been pretty darn dead and have been brought back. During the time we are dead (or deeply sleeping, or in a coma, or whatever) our sense of self isn't somewhere else - it just is gone entirely. There is no persistent sense of self that survives outside our body.
- We don't really call this a "new" sense of self, because it's an emergent property rather than a countable thing. Likewise if a chameleon was green, and then turned red, and then turned green again we wouldn't say it had a "new" green. It was green, then it wasn't, then it was. We are aware, then we're not, then we are.
- When our brains break sufficiently that they can no longer generate this sense of self awareness ever again, it's just over. There's nothing to reincarnate because that sense of self isn't a countable thing and it's gone anyway. Nobody else will have "our" sense of self, or any part of it, because it's not a THING that can be passed around or divided up.
- That feeling you have, that a copy wouldn't be you and that there's something special about the original that would be lost in translation - that's not an actual thing, it's more like sentimental value. It means something TO YOU but it's not an actual measurable or quantifiable value. If we DID replace you with a perfect copy and didn't tell you, you would never know.
To elaborate on that last point:
You (Jabba) and JayUtah try to resolve this in person, and end up having such a good time that you forget all about this argument and spend a week in Disneyworld instead. You have the best time you've ever had anywhere and are left with feelings of platonic affection and memories that will last a lifetime. JayUtah buys you a Mickey Mouse hat, which you promise to treasure forever. I also have a Mickey Mouse hat, I got it off eBay as part of a lot of miscellaneous hats. These two Mickey Mouse hats, due to the wonders of modern engineering and random chance, are
physically identical down to the last molecule and are therefore identical for all real purposes.
You would assign way more meaning to one of them because the one you were given has sentimental value, but if I swapped them when you weren't looking you would be none the wiser and would take the "wrong" hat home. Now you would assign that added value to the one I bought on eBay from HatLover99 because no instrument in the universe could ever tell the two apart.
That's because sentimental value
isn't a tangible thing. Likewise, you feel that two identical people would nonetheless be different in some way. All that would actually be different, however, is the value that you assign to them. So you would
feel differently about them but in actual practice there is no difference and you wouldn't be able to tell them apart if you mixed them up.
I know you're not going to do this even though it would only take like a minute, but here goes anyway: I'm going to list off some things, and I want you to give a yes/no answer -
just yes/no - for each of them. If you respond with a whole paragraph we're probably going to just go into another stupid loop, so I really am begging you to answer all of the below with a yes or a no.
Assuming a physically perfect copy could be made, is there a difference between two completely identical:
1. Jabbas?
2. Other, non-Jabba people?
3. Dead bodies?
4. Plants?
5. Dogs?
6. Bacteria?
7. Rocks?
8. Mickey Mouse hats?
9. Mickey Mouse hats where one of them was a gift from a loved one and one wasn't, but in all physical ways they are identical?
If you could answer all nine of those with a YES or NO we might be able to narrow things down a bit.
