(This is one possible form of the No Cul De Sac Conjecture =NCDSC) Sure, the cul de sac is avoided by reaching the state of unconscious which is then consistent with with many more continuations. e.g. as a rock. I am not sure this makes sense. By definition a cul-de-sac world has no continuation. To be unconscious or dead (never more conscious) means no more experience at all (if that means something). The QTI is based on quantum theory of unitary evolution; not on the survival of memories or consciousness. Those are claimed to be consequences, so they must be justified from QM, not just promoted from conjecture to axiom. Assuming comp, QTI should be a particular case of Comp-TI. But this is complex to analyzed for the reason that we can survive ith amnesia, so that we can never be sure of who is the person who really survive. Comp and QM TI might end up trivial if there is only one person in the fundamental reality. Russell is right. The presence or non-presence of cul-de-sac is a question of points of view. Precisely we have that G* proves the equivalence of Bp and Bp Dp. But the machine cannot see that equivalence. The modality Bp entails the existence of cul-de-sac world at each states, and Bp Dp eliminates those end worlds. People have to go back to the semantic of G or of normal modal logic to see this. In a cul-de-sac world every statements are provable, but none are possible or consistent. With both QTI and COMP-TI we cannot go from being very old to being a baby. We can may be get slowly younger and younger in a more continuous way, by little backtracking. We always survive in the most normal world compatible with our states. But some kind of jumps are not excluded. Brent To avoid the cul de sac event, there would surely have to be a critical stage whereby consciousness diminishes and reaches a form of cusp at the point of lapsing into non existence and thereby requiring the necessity of an extension route or branch to another consistent universe. In short, from the third person POV, the person dies but from the first person -(now primitive) consciousness – state, there is rebirth. I am thinking that before we get to the croaking Amoeba there is a discontinuity in what we understand as consciousness – at least the form that applies to the NCDSC. Now if all this were to be the case, then maybe it says something very specific about the substrate on which consciousness runs. There would be something special about the architecture which the substrate employs to implement consciousness because it relies on a certain mode of decay, facilitating the branching to a new born baby having an appropriate structure (portal?) to secure a consistent extension of the consciousness into another branch. Unless a computer could simulate such a special substrate then it could not be used to implement consciousness. This would mean that it would be wise to say no to the Doctor! – Comp might be false? Comp might certainly be false. But I am not sure I see your point here. There is an infinity of computational histories going through your state. The substrate (matter) is made-of that infinity of computations. The Turing principle (p135 of David Deutsch’s book – “the Fabric of Reality”) would imply that, a universal machine could simulate the physical structure of brains in such a way so as to be able to act as a medium whereby, if the above argument is possible, consistent extensions of conscious physical observers (persons) could avoid cul de sacs. I think that the Turing principle is contradictory with Church thesis. What we can do is to (re)define matter by adding the Dp (= ~D ~p) in each state. It is needed for defining the first person measure one in the case of the first person indeterminacy. matter and physics is a probability/credibility

Now in the case of Parfit's argument, I find considerable doubt that the argument can be made to work. Whilst, if I randomly knocked out 1% of your neurons, you will still be awake, and probably little different from the experience, if I knocked out certain keystone (as the concept is called in ecology) neurons to a level of 1% of all neurons, your brain function would fall apart quite rapidly. Yet to transition from your brain to that of Napoleons would require rewiring those same keystone neurons, and that, I believe casts significant doubt that the continuum is possible, even in principle. Now, we also know that infant minds are not a tabula rasa. So I am sceptical that the transition of a dementiaed mind to an infant mind is possible, for just the same reason. It doesn't have to happen by removal of neurons in a single individual. The transition could happen, for example, by having a series of separate individuals who share a proportion of their predecessors' memories. They don't even have to run on the same substrate, let alone the same brain. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups Everything List group.

Usually people take the comp hyp by assuming that consciousness is related to a physical, or just a single implemented computation, without taking into consideration the infinities of computations leading to the same or equivalent states, as needed from the first person perspective (plural or not). In fine the physical computation is defined by the infinity of computations (executed by the UD, or in arithmetic) leading to the equivalent state, and physical causality emerges from all of them, leading to some multiverse structure observable once we look at ourself below our comp substitution level). If this does not help, try to make your question more specific. It is a difficult subject. You like math, I think. I can define for you the 'arithmetical physical causality': event A causes event B means that BD(BD A - BD B) is arithmetically true, with B and D being the new box defined by the Bp Dp translation in arithmetic.

For one thing they point in opposite directions! I still don't understand how you persist in not seeing the implications of the Stone duality! Oh well, that is your choice, but putting that aside the continuity of 1st person should supervene on the UD, no? It seems to me that from the point of view of the UD there is no before or after or this causing that. To the UD everything is simultaneously given. Additionally, the way that the dovetailing seems to work makes it so that the UD is dense on the space of computations in the same way that the Reals are dense in the continuum. But how can this be?

Only logical impossibility can count. Even physical impossibility is insufficient, because there is always the possibility of mind uploading into machines that may be of arbitrary age. I follow that this observation is not evidence against the NCDSC but am wondering if it is evidence against QTI! If we eventually end up as Tegmark's amoeba then this can be deemed continuous in some sense but hardly immortal. My definition of immortal (which I held for the purpose of my posting) was that it would be more like a continuation of self aware consciousness - ie the ability to recognise I was experiencing an observer moment. Even Jacques Mallah accepted the possibility that people of arbitrarily old age must exist somewhere in the Multiverse. What he couldn't accept was the certainty of getting from here to there, that the NCDSC implies. The refinement of that debate lead to the distinction of ASSA vs RSSA, and the NCDSC. But If we were to find ourselves in a universe in which we alone were arbitrarily very old and all other people had ages that were distributed about a mean of 70 yrs (give or take thirty yrs) then that would lead me to believe I was living in a very improbable universe - I might suspect self delusion! I often wonder about so called delusional conditions and their validity? In any case I would have suspected that the NCDSC would bring me into the most probable universes on the whole ( RSSA?). Hence if I was living to a very ripe old age then I would expect others to be sharing this perception too along with others who were even much older than me. I agree that we might just be on the verge of discovering the uploading of minds into computers, but if I had been a viking in 200 AD this would not really be realistic - yet they too must still be alive somewhere if the defined QTI I am considering is valid.

Hi Bruno Maybe what I am trying to say is that very old or dying brains might deterorate in a specific way that allows the transition from an old to a young mind i.e. the decaying brain becomes in some way homomorphic to a young brain. Indeed this defines the consciousness I am considering and is therefore subtrate dependent. If all of physics can be simulated on a computer then no problem. If you accept the classical theory of knowledge, it is easy. Computer are already conscious. They have not the tools to manifest their consciousness, and by programming them, we don't help them with that respect. Consciousness is not programmable. It exists in Platonia, and a universal machine is only a sort of interface between different levels of the Platonic reality (arithmetical truth). This is an interesting comment! Are you saying that everything including consciousness really emanates from platonia? Would you agree that we exist eternally in platonia? If so then perhaps we need only consider computationalism /QM as a means of comprehending the steps to this understanding. This platonic realm is very useful but hard to pin down as a concept.

The most probable way I can think of is that as you get older, medical science advances and everyone lives longer, then eventually mind uploading becomes available. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups Everything List group.

Eric Vandenbusche is currently trying to optimize the G* theorem prover to get an answer. And here I thought I was making progress in understanding Bruno's thesis.

Best Nick Is not a sufficiently young brain not isomorphic to a unconscious brain? After all, the brain of a human fetus has to grow to come sufficient level of complexity to turn on...
