For gods sake! In a world that contains first person
experience duplicating machines there is no such thing as
THE first person experience,
Of course there is.
By the definition of personal identity that both you and me are using,
and by the definition of first person used here, it is plain obvious
that "the" first experiences exist, and indeed, due to the
duplication, exists in the two places (and are incompatible from the
first person views). The guy in W, and the guy in M, will know exactly
what I was alluding with "THE", and one will answer "THE" has been
resumed into "Moscow", and the other will answer that "THE" has been
resumed into Washington, and both will expect this to happen again if
they reiterates the experience, helping them to make sense of the
question if they lacked the imagination to predict this. In the
iterated case, if asked which histories they bet on, it is plain
obvious that the vast majority will live a random experience, and
predict correctly that this will continue if they repeat it again, and
the verification criteria (entailed by the definition of first person
experience) confirms this.
and no matter how often the phrase is repeated it remains just as
stupid as it was the first time it was uttered.
We agree on this.
You might listen to yourself (which is exactly what you refuse to do
in the duplication thought experience). You predict that you will be
both the W-guy and the M-guy, which is of course correct in the 3p
view (that is the protocol!), but as far as being a description of
first person: it is wrong: both will tell you that the experience has
become asymmetrical at the very second when the door is open: they see
a unique city that they were unable to predict seeing.
