Sebastian:
I see your point that given the atoms are what they are, they are 'the same person', but can't get around the sense that it still matters on some level.
What if cryonics were phrased as the ability to create an identical twin from your brain at some point in the future, rather than 'you' waking up. If all versions of people are the same, this distinction should be immaterial. But do you think it would have the same appeal to people?
Suppose you do a cryogenics brain scan and create a second version of yourself while you're still alive. Each twin mi...
I can understand why creating a reconstruction of a frozen brain might still be considered 'you'. But what happens if multiple versions of 'you' are created? Are they all still 'you'? If I create 4 reconstructions of a brain and put them in four different bodies, punching one in the arm will not create nerve impulses in the other three. And the punched brain will begin to think different thoughts ('who is this jerk punching me?').
In that case, all 4 brains started as 'you', but will not experience the same subsequent thoughts, and will be as disconnected f...
I can think of a few reasons why you would do this, although I'm not sure which one you had in mind.
Primarily, it's to evaluate the extent to which we commenters accept what you say on face value, particularly when we're not well informed to begin with. I don't mean picking at the specifics of examples, but whether we're evaluating what you're saying for internal consistency between posts.
For instance, the 'many worlds' argument you've presented DOES seem more plausible that collapse, but it certainly still seems mysterious. Having universes sprouting in a...
Sebastian:
Take this as a further question. One of the key distinctions between the 'you you' and the 'identical twin you' is the types of sacrifice I'll make for each one. Notwithstanding that I can't tell you why I'm still the same person when I wake up tomorrow, I'll sacrifice for my future self in ways that I won't for an atom-exact identical twin.
If you truly believe that 'the same atoms means its 'you' in every sense', suppose I'm going to scan you and create an identical copy of you on mars. Would you immediately transfer half your life savings to a ... (read more)
