If he's a devout Muslim he believes he will go to heaven with 77 virgins
when he pushes that button, but as I said I really don't care what he
believes will happen, I care about what will happen.

Yes, but he is not the only Helsinki man because YOU HAVE BEEN DUPLICATED,
and that means the 1P view has been duplicated too, and that means the 1P
view from the 1P view has been duplicated too, and that means the 1P view
from the 1P view from the 1P view has been duplicated too....

Once upon a time there was a equation called X^2=2, and X always wondered
what number he would turn out to be, and then one day a magical munchkin
mathematician solved the equation and said that X was plus 2 and minus 2.
All was well until minus 2 said the mathematician was wrong about who X was
and that caused great strife in the land. Minus 2 said he was the solution
to the equation and what's more he could prove it, and minus 2 said he was
one and only one number and he certainly wasn't plus 2, so the great
mathematician was wrong and was unable to predict what X would be.
Unfortunately the number plus 2 started making similar claims about being
the solution to the equation and got into a huge fight with minus 2, but
they all added up to nothing.

There is nothing in those diaries, nothing about the bodies and no third
party description that I failed to predict.

If a problem has 2 solutions that means it does not have one and only one
solution. How profound.

Mr. Washington man are you also the Helsinki man? Yes. Are you now in one
and only one city and is that city Washington? Yes.
Mr. Moscow man are you also the Helsinki man? Yes. Are you now in one and
only one city and is that city Moscow? Yes.
Mr. Helsinki man, that is to say the guy who is still experiencing
Helsinki, are you still the Helsinki man? Only dead silence can be heard as
And so "W and M" ALWAYS occurs, that is to say the Helsinki man from the
Helsinki man's viewpoint will be the Washington man and the Helsinki man
from the Helsinki man's viewpoint will be the Moscow man. And the Helsinki
man from the view of the guy who stayed in Helsinki no longer has a
viewpoint of any sort.

And you are still confused by the fact that "I" is no longer singular
because I HAS BEEN DUPLICATED AND SO HAS ALL OF I'S VIEWPOINTS.

Which what? I guess you mean which person goes to which city, I don't know
what else you could mean. The answer is that the Washington man goes to
Washington and the Moscow man goes to Moscow. Where is the indeterminacy?

There would be a single answer if "he" were singular but it is not because
HE HAS BEEN DUPLICATED, and that means his viewpoint from his viewpoint has
been duplicated too.
"W or M, but I can't be sure of which one".
If I demand a single answer from the question "are human beings male or
female?" I will always be able to find a counterexample to prove you wrong.
Can you find any great philosophical significance from that fact?

I agree, so the answer to the Helsinki man's question is that he, the
Helsinki man, will survive in both Moscow AND Washington from the Helsinki
