The 'you' I used referred only to the pre-duplication person, who is making the choice, and who is singular.
The view you describe is the view I described in the last paragraph of my previous comment (the one you replied to). I understand and agree that you decide things for all identical copies of you who may appear in the next second - because they're identical, they preserve your decisions. But you can only anticipate experiencing some one thing, not a plurality.
If someone creates a clone (or several) of me, I may not even know about it; and I do not expect to experience anything differently due to the existence of that clone.
If someone destroys my body, I presume I'll stop experiencing, although I have no idea what that would be like.
By inference, if someone creates a precise clone of me elsewhere and destroys my body at the same moment, I won't suddenly start experiencing the clone's life. I.e., I don't expect to suddenly experience a complete shift in location. Rather, I would experience the same thing (or lack of it) that I would experience if someone killed me without creating a clone.
Yes, this begs the question of why I experience continuity in this body, since physics has no concept of a continuous body. And why do I experience continuity across sleep and unconsciousness? I don't have an answer, but neither do the alternative you're proposing. The only real answer I've seen is the timeless hypothesis: that at each moment I have a separate moment-experience, which happens to include memories of previous experiences, but they are not necessarily true - they are just the way my brain makes sense of the universe, and it highlights or even invents continuity. But this is too much like the Boltzmann's Brain conjecture - consistent and with explanatory power, but unsatisfying.
"You" sure seemed like it referred to only one of the postduplication individuals here:
In the second option, you are not affected in any way.
(This when one of me seems to be quite seriously affected, in that you plan to torture and kill that one.)
And here:
You won't privilege what you actually experience.
(This when I do privilege what I actually experience, and simply think of "I" in these futures as a plural.)
you don't know in advance which of ten thousand copies you'll be
(But I'll be all of them! It's not as though 9,999 o...
From the dawn of civilization humans believed in eternal life. The flesh may rot, but the soul will be reborn. To save the soul from the potential adverse living conditions (e.g. hell), the body, being the transient and thus the less important part, was expected to make sacrifices. To accumulate the best possible karma, pleasures of the flesh had to be given up or at least heavily curtailed.
Naturally the wisdom of this trade-off was questioned by many skeptical minds. The idea of reincarnation may have a strong appeal to imagination, but in absence of any credible evidence the Occam’s razor mercilessly cuts it into pieces. Instead of sacrificing for the sake of the future incarnations, a rationalist should live for the present. But does he really?
Consider the “incarnations” of the same person at different ages. Upon reaching the age of self-awareness, the earlier “incarnations” start making sacrifices for the benefit of the later ones. Dreams of becoming an astronaut at 25 may prompt a child of nine to exercise or study instead of playing. Upon reaching the age of 25, the same child may take a job at the bank and start saving for the potential retirement. Of course, legally all these “incarnations” are just the same person. But beyond jurisprudence, what is it that makes you who you are at the age of nine, twenty five or seventy?
Over the years your body, tastes, goals and the whole worldview are likely to undergo dramatic change. The single thing which remains essentially constant through your entire life is your DNA sequence. Through natural selection, evolution has ensured that we preferentially empathize with those whose DNA sequence is most similar to our own, i.e. our children, siblings and, most importantly, ourselves. But, instinct excepted, is there a reason why a rational self-conscious being must obey a program implanted in us by the unconscious force of evolution? If you identify more with your mind (personality/views/goals/…) than with the DNA sequence, why should you care more for someone who, living many years from now will resemble you less than some actual people living today?
P.S. I am aware that the meaning of “self” was debated by philosophers for many years, but I am really curious about the personal answers of “ordinary” rationalists to this question.
