Well, you probably still *feel* that the Earth is flat
as you walk around on it; but you *know* better.
You *could* adopt the point of view I espouse in my
first paragraph, above, and then it wouldn't be an
inconsistent mess, would it?

Well, it would *definitely* be someone else, not you!
It simply definitely true that if your body woke
tomorrow with all Bush's memories, and yours were
expunged from the Earth, then you'd be dead (here).

Yes, the good old Ship of Theseus. IN the ship case
we know all the facts; the problem is which one we
want to call the "real" Ship of Theseus. As for me,
both are the Ship of Theseus in this way or that.

Well, yes, it would be arbitrary to say whether
or not you are the same person you were ten years
ago.  Or at age 10.  But there *are* important
FACTS OF THE MATTER, in my opinion.  One fact of
the matter is that you are the same person you
were yesterday, and will be tomorrow. It's perfectly
clear that what is up for grabs is the *degree* to
which one is an earlier or a later version.

>From the viewpoint of physics, your duplicate across
the room created a moment ago much more vastly 
resembles you than the "you" of a month ago. Since
you are the same person that you were a month ago,
then it follows that you are the same person as
your duplicate across the room.  That it doesn't
*seem* that you are the same person is just one of
those things (like MWI itself) that physics is 
trying to tell us and that we have to just get used to.

Not quite!  It turns out that everyone who knows them
regards identical twins as different persons. And so
regards them, I am pretty certain as different people
in a way that they were *NOT* so regard you and your
duplicate.  You and your duplicate---created yesterday,
say---would be SO SIMILAR I claim, that people would
regard you as the same person.  It seems that identical
twins always do have slightly different personalities,
and that a lot of the differences they exhibit were
created during the nine months before birth.

Okay, you can't.  But you might be able to
save your duplicate across the room several
hours' torture at the cost of a few minutes
torture to your local version, and you should
sign up for that.  You should continue to 
sign up for that so long as you have the
