Okay.  I agree.  I too believe in the is/ought barrier,
if that's what you're saying.

Oh yes. Trying to extend what "I" means given all the
new possibilities is not easy!

Well, you mean one instance of me (who you refer to as
"you") will *watch* the other duplicate. The *experience*
you're referring to will be the copy's.

That's right.  When all is said and done, tomorrow someone
exceedingly similar to me will get up (but with an extra
fiver).  But that happens anyway.  Tomorrow someone *just*
like me will get up in my bed anyway, even without strange

NOT AT ALL.  It is axiomatic in these discussions that the
subject is as *selfish* as can be imagined. I don't believe
that any "ought" has slipped in here (though thanks for the
warning from Hume). Perhaps I *ought* to sacrifice myself
to save 1000 Australians, but, if I am to act selfishly,
then I *ought* not in order to maximize my own benefit.

But my use of the word "ought" in this last sentence is not
the moral "ought". It means what one would expect, e.g.,
you ought to go outside if you want some sun.
