Others, I thanks John Clark for giving me the opportunity to sum up the basics.
Of course anyone can ask for a precision. I train my pedagogy. Grayson, don’t hesitate to read my sum up here: http://iridia.ulb.ac.be/~marchal/publications/SANE2004MARCHALAbstract.html Download the slides, and read the argument in 8 steps. I mean, it seems you want to understand, OK? I am a teacher. I am aware that when people want to not understand, they can be quite gifted in the task. > On 30 May 2018, at 15:26, John Clark <[email protected]> wrote: > > > > On Wed, May 30, 2018 at 5:46 AM, Bruno Marchal <[email protected] > <mailto:[email protected]>> wrote: > > > Just try to refute step 3 without eliminating the distinction between > first and third person view, > > Just try explaining what unique thing the personal pronoun “you” refers to in > a world that contains first person view duplicating machines.

It means exactly the same as the one used informally by Everett in his short and long texts. The 1p-you is defined by the sequence of memories personally accessible, like the personal diary taken by the candidate for some duplication, or the person in the superposition state seeing a dead cat + seeing a cat alive. In both case, after the result of the experience, the 1p-you have multiplied (in the 3p “reality”) and each assess a precise sharp results of the measurement (like “Washington”, or “cat alive”, etc.). I remind you that your argument that in the two situations the doppelgängers have different chance to meet, is not relevant, or just add in the thought experience that someone has build a an unbridgeable wall between Washington and Moscow. The 1p-you are associated to series of machine states, and it is the sequence of memorised measurements, or local input readings building your personal history. The 1p-you is always unique from the 1p-you point of view. After a 10 times iterated duplication, each resulting persons surviving that experience, among 2^10, have a unique precise personal history given by a precise sequence, like say 100000100111011. As the 1p-you is defined by that sequences. The 3p-you is given by your body, up to some local representation with respect to some universal number/machine/combinator or more general. The only difference is that Everett does that in a universal quantum universal machine, the “universal” wave. I do it in arithmetic, or in any Turing universal machinery (phi_i) I recall that phi_i is the sequence of partial recursive/computable function, that you can enumerate by enumeration all programs in any presentation of a programming language or computer, in the sense of Church, Post, ... All I say is that if computationalism is true, the quantum universal dovetailing, the wave, the unitary rotation, has to be justified by some precise intensional variant of Gödel’s arithmetical (and sigma_1 complete) predicate of provability/believability. It is not a matter of choice, or you can always invoke some magic to stop the reasoning. If you study a bit of math, and what is a universal machinery (the phi_i and w_i), you will understand that I introduce (4 + 4 * infinity ) nuances of “you” and “me”. Each one having a precise definition either in first order arithmetic, or in in term of such arithmetical relations. I understand it is shocking for the strong believer in a primitively material universe(s), or in physicalism, as you can sum it all by it is in the head of the universal (church-Turing-Post-Kleene) machine. The universal machine is not a theory of everything, it is a door to the unknown. It is a baby god, which can become a terrible child, also.
