Yes, Bruno Marchal certainly has repeated this question many
many times, and after each and every time John Clark has begged
Bruno Marchal to stop using personal pronouns because in
duplicating chamber thought experiments like this it is not at all
clear what the personal pronoun "you" refers to.
Except that we have given the precision needed. "you" refer to the guy
who remember being John-Clark-in-Helsinki. In this case, it refer to
you in Helsinki, and the question concerns which of the next guy the
guy presently in Helsinki will feel to be.
And Bruno Marchal has without exception always refused John
Clark's simple request.
No, I have given it, and so well that we do agree on this.
Why? John Clark theorizes it's to hide sloppy thinking, at least
John Clark can't think of another reason for not making such a
change that though simple would expose many logical flaws and
assumptions to the light of day. Without personal pronouns there
would be no place for crap to hide.
Pronouns are my expertise, and if you were really interested you would
have study the small amount of computer science to see how the math
part handle them. You can still ask, I teach this every year.
But for UDA, you need only the precise and simple definition given, on
which you have agreed, and just pursue the reasoning. For a mysterious
reason, you seem unable to put yourself in the shoes of any of the
recontituted person, as you still deny that in Helsinki you know with
certainty (modulo the hypotheses) that you will see only one city
after pushing the button. But you have not yet say what happens: you
die? you feel to be in two cities at once? or what?
