Just to clarify, Jabba, when you are calculating P(E|H) it doesn't matter whether or not H is correct: you have to assume that H is correct and calculate the likelihood as if H is correct.
I've said the above, and am still waiting for a reply. You must calculate the probability of you existing in H as if H were correct. Since, in H, there is nothing special about a sense of self as it is just an emergent property of the brain your argument would apply equally to things without this property.
Under H while there are of course physical differences between a rock and a living human being those differences are, in the grand scheme of things, trivial. Calculating likelihood of a specific clump of matter is the same whether that matter is a person, a giraffe, a redwood, or a rock. Therefore if your argument is that under H you are unlikely to exist, I can apply this same logic to any particular clump of matter.
By your own argument, this would then imply that rocks are immortal. You haven't responded to this except to say, essentially, nuh-uh.
SOdhner & Waterman,
- Do you agree with Dave?
I already answered this and you didn't reply to me. If I have two identical snowglobes, one of which I just bought at Walmart and one of which you were given by the love of your life in a little cafe in Vienna after a whirlwind adventure through Europe and these two snowglobes were physically identical down to the last molecule, then they would be 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" snowglobe home. Now you would assign that added value to the one I bought at Walmart 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. (On a related note, I wonder how many identical twins have accidentally switched names some time after birth because their parents lost track of which was which...)
Stop that. Stop individually polling your critics, probing for a perceived crack into which you can drive the wedge. Stop stalling the argument while waiting for individuals to respond. If you're so anxious about individual feedback, and insinuate that the argument can't proceed without it, give
this a go.
If you were wondering, Jabba, I agree with that too. You avoid clear questions, and then ask if we agree on things we've already said we agree on. It's a very wasteful use of your limited time here.
Dave, SOdhner and Waterman,
- So, I'm claiming that my duplicate self would be different from my original self (me) in more than separateness -- I would not be brought back to life by the copy. The new self would not be me. That would be a big difference between the two.
- It is that experience of self that I claim is unimaginably unlikely under H.
- Do you still disagree?
We've all said a bunch of times that we disagree with you on this. As above, this is equivalent to sentimental value. You feel like you are special and so you wouldn't lend the same value to a copy. That copy also wouldn't lend the same value to you. But objectively, scientifically, under H there is no difference. And since your argument requires that you calculate the odds under H you must do this calculation as if H were correct. That means you CANNOT include your sentimental value into the equation.
In a hypothetical scenario where we could make a perfect copy of your physical body, it would be a perfect copy of you - because under H the physical body is all that exists. Saying otherwise is to include ~H in H which obviously screws up your formula really badly.
- But you agree that I would not be brought back to life in the new self. IOW, the fact that the new self would not be me, but the old self was, would not make for a difference (and a significant one) between the two selves?
You're assigning special value to the *I* in that sentence, which is perfectly natural and understandable. It's the teleporter problem, this has been done to death. But from a materialistic point of view there's no difference. Just like sentimental value, it's a perceived difference but not an actual one.
I'd like to try something, I really hope you will respond to this. I think it would be very helpful to move this argument along. 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. Snowglobes?
9. Snowglobes 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.
