John, lemme correct a possible misunderstanding. *I* do not disagree that the two are different people. It did seem odd to me that *you* expressed the same view, however, since you have previously stated that you believe (correct me if I err) that two physical instances of exactly the same pattern of mind are really only one person. This seems to me to imply that one of the two physical copies we seem to see is merely illusion, but I gather that this doesn't follow, to you. I do not understand that, and perhaps this is partly to blame for my viewing your position as inconsistent where it concerns two copies separated by only trivial amounts of time.

Again with the amnesia argument: if you wake up and are told that it is 1999, and that you have been in a coma ever since that nearly-fatal accident last September, do you think that the person that existed in September *died*, if you cannot remember having been him?

I'd say that less than a second is sufficient, but then, I also think that both copies are separate people.

But *also, from my point of view, a perfectly identical copy is not me (since if you kill him, I go on living).
