Imagine you are destroyed in your sleep by aliens and replaced by an atomically identical duplicate. Would you call this "you"?

If not, what if the aliens recycled the atoms from your original body to make the new body, putting each original atom into the same original spot with the same position and momentum (ignoring quantum and uncertainty principle).

What if they recycled 99% of the atoms from your original body, but swapped 1% of them for different atoms?

What if they only destroyed 5% of your brain and reassembled that destroyed portion, leaving the rest of you untouched? What about 50%?

What if they waited 1 planck moment before reassembling you versus 5 seconds?

Where is your dividing line in this scenario space between "that's really me" versus "that's just a copy and is not really me" ?

The functionalist answer, as I understand it, is fungibility across time and copies when arriving at definitions of words like "you".

The functionalist answer is not that > 1 copy can communicate telepathically or supernaturally share experiences is a dualist sense. They are still causally independent physical entities.

None of these scenarios would result in "me" from a monist perspective. The destruction is a discontinuity point, I died there and then, and then the next planck moment a new being was created with all my memories. But "I" died.

The functionalist answer, as you understand it, is dualist. It says "something" survived the utter complete destruction of the physical body and was "put back in it" once it was reassembled. If "it" survived the complete physical destruction of the body, it must be somewhere else, detached from the body.

And, you know, there's really nothing wrong being dualist. I do not mean to denigrate that specific worldview. What is problematic is claiming to be a staunch monist while holding dualist positions.

  • What if they destroyed and reassembled only 0.5% of your brain? What's your dividing line? 0.36%? 0.0188%?

    > The functionalist answer, as you understand it, is dualist.

    I think you're misunderstanding that words are social constructs which can point to abstract categories rather than necessarily single concrete objects at a particular moment in time (although words can also do that).

    Like if you have multiple tennis balls, each ball is still a tennis ball, despite each ball being different, because "tennis ball" is a social construct and an abstraction that's an indirection to a certain concept. In the worldview I am talking about, the word "you" is an indirection to a mind that is indistinguishable in content and experience from the one you have right now, with the property of fungibility across modalities, time and space.

      Apologies, I read too quickly and skipped over this. See one of my sibling comments. I concede this is problematic for my position and I need to think harder on how to solve it, but I don't think it's unsolvable. The placeholder answer is that there must be a certain level of damage -- the precise % probably doesn't matter as much as exactly which parts you destroy -- that is incompatible with keeping continuity.

      For the rest, as a social construct, if we incinerate me to create a clone of me that is identical to the original at the subatomic level I agree that, for everyone else in society, it is me. But my self has still died and whatever replaced it is having its own experiences. And it matters very little what everybody else thinks: if tomorrow an imposter convinces everybody else that they are me, they aren't me for me. Their experiences aren't magically beamed to my brain.

      Your tennis ball example is again a textbook dualist position. You can have a tennis match with different balls which is functionally identical to have it with the same ball, because the ball in the game is an abstraction that lives _outside_ the ball itself. But, assuming balls can feel when they are hit by the racket, the ball you used in the previous point and now is lying on the sideline does not feel being hit when the next point starts with another ball.

  • As a monist who holds the view that you’re claiming monists can’t legitimately hold, I don’t see any difficulty at all in squaring these ideas:

    - there is no separate “stuff” that minds are made out of, no privileged plane of existence specific to minds; minds are just patterns like everything else

    - destroying an instantiation of a pattern != destroying the pattern

    And speaking of squaring ideas – if I draw a square on a piece of paper, and then light that paper on fire, I haven’t destroyed the concept of a square. I can always draw an identical square on another sheet of paper. If the square had consciousness, it’d be none the wiser.

    • > If the square had consciousness, it’d be none the wiser.

      This is exactly what don't know, and is interesting to explore.

      > there is no separate “stuff” that minds are made out of, no privileged plane of existence specific to minds; minds are just patterns like everything else

      So if your brain was somehow cloned, you'd exist in two places at the same time? It seems possible for two separate consciousness to have the same memories and be identical in all respects, and yet still not be the same.

      To illustrate, two instances of a programs can share the exact same binary code (the "pattern") and yet they are separate instances.

      If you have a son and you kill him, you haven't destroyed the concept of a son. You can always make a new son. If the son had consciousness, it’d be none the wiser.

      Is that the same son? Do you not go to prison for murder?

  • If this actually happened, would the 'I' that replaced you be any wiser. How do you know this hasn't happened to you already? Maybe multiple times per second?

    > It says "something" survived the utter complete destruction of the physical body and was "put back in it" once it was reassembled. If "it" survived the complete physical destruction of the body, it must be somewhere else, detached from the body.

    The information of how to put your body and mind back must have survived somewhere, in the alien mind for example or the machine they used. But the information would still be in (a medium in) this universe and bound to this universe physical laws. I would say this is still a monist position.

    A true dualist believes that consciousness survives outside of a medium in this universe.

    • > If this actually happened, would the 'I' that replaced you be any wiser. How do you know this hasn't happened to you already? Maybe multiple times per second?

      If this is true, that the body dies every planck time and the mind survives it, then it simply means the dualist position is true.

      > The information of how to put your body and mind back must have survived somewhere, in the alien mind for example or the machine they used.

      I'm sorry, but you're circling back to the first message I wrote. You are giving to information magical properties that it cannot have, because they lead to a contradiction. With the same information you can make multiple copies of me at the same time. But if you make two, the experiences of one do not get magically transmitted to the brain of the other. So those are two distinct selves, even if they are made with the exact same information. This clearly does not work. It's the same issue of mind uploading that I initially argued about.
