In particular section 3 goes to great pains to describe the
importance of the first person / third person distinction.
Of course it's important, but I didn't need Bruno's help to figure
that out. And I especially agree when is says "To avoid linguistic
confusion it is crucial that we distinguish between the outside view
of the world [from ] the inside view". Yes, we must avoid
linguistic confusion!
It's true that in everyday usage there is no linguistic confusion
and it would be silly to keep asking "what do you mean by the
pronoun "you?", but this is very far from everyday usage. This is a
thought experiment involving identity duplicating machines and is a
vital part of a proof that is trying to find something new about the
very thing that is being duplicated, identity. Under those very very
exotic circumstances the meaning of the personal pronoun "you" is
far from obvious. And if the meaning of "you" is vague then the
difference between 1p and 3p is vague too, and that is not
acceptable in a proof that claims to be mathematically precise.
So when Bruno asks "will you in Helsinki survive the duplication?"
or "what city will you see?" it depends entirely on what "you"
means. To me, and to Bruno too before he panicked and backpedaled,
"you" is the guy(s) who remembers being the Helsinki Man; thus I
would answer that yes "you" will survive and "you" will see both
Moscow and Washington. And if the ASCII sequence y-o-u means
something different in another language then John Clark would answer
the questions differently.
I give the two definition of the pronouns used in the reasoning, and
often confused by the use of an identical term in natural language,
but clearly distinguishes in UDA step 2, and the next one. The 1-you,
basically "your" definition, or simply the content of the diary taken
by the experiencer with him, and the 3-view, the content of the diary
of an external (not entering in the teleportation box).
But you stop the thinking before taking that distinction further into
account, and I don't know why.
