I'm sorry, I didn't mean to imply that there was some non-physical
aspect of the mind. I can see how what I wrote could be read that
way. I was only trying to explain that if I were copied into a new
being, that the physical aspect - how high I can jump, what I look
like, etc. - would be one component that would be of some importance
to me, but who I *really* am is defined by my thoughts. The thoughts
are determined by the chemistry of the meat, though.

I was trying to define "me" in more than just in terms of the
hardware (in this case organic). If you run the above definition on
some future quantum computing hardware and it still roughly worked
the same, it would still be "I". I probably went too far in trying
to define the importance of separate aspects of the same physical
thing, and then just confused my stance on this position. Too much
crack, I'd guess. :)

I'm not sure what you're arguing here. I concur that if both the
original and copy exist that they will diverge from one another.
What conclusion are you drawing from that?

No, I said that if you're restored from a just-made backup at the
moment of your destruction, you have effectively the same
consciousness, and that any feeling that your continuity has been
eliminated is sentimentality.

Note the question in my post regarding use of a futuristic
teleportation device that is essentially destroying then recreating
you from information. I may have sentimental problems about losing
my original meat, but my continuity is maintained.
