And Bruno's prediction was that somebody by the mane of "me" would say "I
saw W or M", but nobody said that, certainly not "me". This entire problem
is caused by the inability of some to realize that in a world that has
working duplicating chambers and pronouns are still used with abandon just
like they are in our world without duplicating chambers then the end result
can only be tautologies or gibberish.

If the W-man looks around and the M-man does not then they are no longer
identical, and if nobody looks around then there is no W man or M man
regardless of where they are, there is just one man, the Helsinki man in a

Then why do you keep complaining that I've answered the question "only in

In this case a conscious being is different in the 3 p and the 1p. I can
think of examples where you and another are identical in the 3p and the 1p,
and examples where you and another are identical in the 1p but not the 3 p,
but I can't think of a example where you and another are identical in the
3p but not the 1p. Can you?

You admit that it's impossible to have 2 brains identical from the 3p but
not from the 1p; and yet you confidently state the above. It does not

And if you've changed your mind then you've changed your brain too, you've
changed the state of your brain because mind is what the brain does.

That is NOT what I agreed to! After opening that box and seeing different
things they are no longer each other, they are separate people and
different from each other from BOTH the 3p and the 1P view, and this in no
way contradicts the fact that they both retain the right to be called the

I try hard to understand the question asked, but in the middle of a
ambiguous pronoun blizzard it is very hard indeed.

Each of them? In Helsinki there is no "each of them" for the Helsinki man
to pick out, there is only one person. The Helsinki man can say the one
that sees Moscow will be the Moscow man and becomes the Moscow man by
seeing Moscow, and the one that sees Washington will be the Washington man
and becomes the Washington man by seeing Washington. I don't understand
what more you expect the poor Helsinki man to say.

If Heisenberg's Uncertainty principle did not exist then the world would be
different, I could measure both the position and velocity of a particle
with infinite accuracy, and that's how I know it's talking about something
real. Suppose, just suppose that this "1-P indeterminacy" stuff of yours
did not exist, how would the world be different? Without "1-P
indeterminacy" how would the Helsinki man respond to the question "what
city will you see?" and even more important how could we confirm the
prediction after the duplication? If this question can't be answered then
"1-P indeterminacy" doesn't mean anything.

I don't know what "comp" is and I don't know what "self-localization" is
but I can predict that if I see Moscow then I will be the Moscow man and
see Moscow. Not deep but very true.

If 2 experimenters of equal skill and reputation produce reports on a
experiment that are 100% in conflict with each other than I, a third party,
am no wiser about what is really true than I was before either experimenter
did anything.

If you put a gun to my head I couldn't say what you're talking about.

Yes, remind me again what we're arguing about.

Yes, remind me again what we're arguing about.

Is it the 1-I or the 3-I that am not currently duplicated? And how would
"I" know if "I" was duplicated or not?

If "I" was duplicated then "I's" diary was too.

I don't think so, I'm pretty sure I would have remembered that.

I'll settle for just one example above, and I don't see it.

Yes. And now that we've gotten all that out of the way I'm going to repeat
my request yet again, without invoking the supernatural please give a
example of 2 beings identical from the 3p but not from the 1p.

And should I shoot that other fellow before he can check the box for the
other city? That's the only way to get a single unambiguous result from the
experiment; but then again the experiment is symmetrical so if one has a
gun the other does too. So either all the boxes  in the Washington and
Moscow column in the lab notebook get checked or none of them do.

The result will NOT be random at all, the result will be that every box
that can be checked will be checked, and as a result nothing will be
learned from the experiment.

And Bruno forgot to explain who "you" is in a world with duplicating
