Subject: More of the Duplicates Paradox

More handwaving from Mike Perry et al on the issue of survival.

1. Suppose I fall asleep, am destructively scanned, and two
duplicates of me are created, one looking at the sun, and the other
looking at the moon. While you may be able to say, neither one of
them remains me for very long (as you said in your last message),
you still have yet to answer the question, when I fall asleep, and
wake up, what do I see? The moon or the sun? I cannot possibly see
both.

The correct answer to this question is that I will see neither,
because I was destroyed. However, I would like you to answer this

2. Imagine someone making a duplicate of you while you are awake.
The duplication process takes only 1 hour. After the duplicate is
made, you talk with him for a few hours, recounting childhood
memories, and then take him to dinner and a movie. Then, after you
have concluded your day, I come to you, take out my pocket knife
moves no more.

Here is my question for you: assuming I let your duplicate live,
would you consider the survival of your duplicate to be your own
survival?

scenario is identical to a different one, in which an
anesthesiologist puts you to sleep, you have some operation, and
then you wake up.

Why? Because the drugs the anesthesiologists use frequently include
an amnesiac ('just in case'), so you will forget everything that
happened approximately six hours prior to the operation.

In the first scenario, you and your duplicate were identical 6
hours ago, but then diverged. In the second scenario, you lose all
your short-term memories, thus reverting to an earlier self.

If you want to be consistent, you would have to say that the
duplicate DOES constitute your survival, even though I stabbed you
so many times, and you died a horrible death. In fact, if presented
with the situation, if I asked to stab you as a mere academic
exercise, you should have no problem with that (provided I gave you
some strong painkiller), because after all, you survive in your
duplicate, so there is no need to be concerned with the particular

Here I think many people will diverge from you. The survival of the
duplicate cannot be considered your survival in any useful way.

You are that hunk of matter in your head we call a brain. Protect
it well.

Richard B. R.
