These might be badly composed so feel free to fix them. ;-) 1) If my current state is equivalent to a 4-manifold and the next state is also, what is connecting the two? Markov's proof tells us that it is not a algorithm. So what is it? Markov theorem says that giving two arbitrary states, it is undecidable to know if a computation will relate those states or not. It does not say that some states are not algorithmically linked. With computer it is not in general possible to know in advance if states are related by computations. If they are, this can be usually decided, but if there are not , well there are no algorithm for deciding that in general. 2) Is there another equivalent set of words for the physical world is the limit of all computations going through your current state? 3) Is there at least one physical system running the computations? Is the physical universe a purely subjective appearance/experience for each conscious entity? What is it that shifts from one state to the next? 4) What is the cardinality of all computations? Aleph_0, when see in the third person picture. 2^aleph_0, when seen in the first person picture (well, the 3-view on the 1-views, because it is 1, from the 1_view on the 1_view). In that case, arbitrary sequence of natural numbers play the role of oracle. 5) Is the totality of what exists static and timeless and are all of the subsets of that totality static and timeless as well? Yes, for the basic ontological reality. No, for the epistemological reality. 6) Does all succession of events emerge only from the well ordering of Natural numbers? Not for the physical events.

I gave the algorithm in LISP (and from this you can compile it into a Turing machine). What it does is computable, in the 3-views, but not in the 1-view (which 'contains' consciousness and matter). A simple pseudo code is begin For i, j, k, non negative integers Compute phi_i(j) up to k steps end The relation 'phi_i(j) = r' is purely arithmetical. The UD is just a cousin of the universal machine, forced to generate all what it can do. It has to dovetail for not being stuck in some infinite computations (which we cannot prevent in advance). The existence of UMs and UDs are theorem of elementary arithmetic. The UD gives the only one known effective notion of everything. This is debate that has been going on since Democritus and Heraclitus stepped into the Academy. Can you guess what ontology I am championing? That is what goes into defining meaningfulness. When you define that X is Y, you are also defining all not-X to equal not-Y, no? No. Unless your simply defining X to be identical with Y, a mere semantic renaming, then a definition is something like X:=Y|Zx. And it is not the case that ~X=~Y. OK. When you start talking about a collection then you have to define what are its members. I'm not talking about a collection. You're the one assuming that all 4-manifolds exist and that everything existing must be computed BY THE SAME ALGORITHM. That's two more assumptions than I'm willing to make. Is a universal algorithm capable of generating all possible outputs when feed all possible inputs? I dunno what a universal algorithm is. What you describe however is easy to write: x-input print x. I think a better answer is a Universal Turing Machine, or universal computable function code. It is a number u such that phi_u(x, y) = phi_x(y). This exist provably for all known and very different powerful enough 'programming language' (systems, numbers, programs, ...), and it exists absolutely, with Church thesis. Bruno What exactly is an algorithm in your thinking? An explicit sequence of instructions. Absent the specification or ability to specify the members of a collection, what can you say of the collection? This universe is defined ostensively. Interesting word: Ostensively. Represented or appearing as such... It implies a subject to whom the representations or appearances have meaningful content. Who plays that role in your thinking? You do. When I write this you know what I mean. And are we alone in the universe? You seem to take for granted the existence of others. I wouldn't say taken for granted. I have some evidence. Brent Brent What is the a priori constraint on the Universe? Why this one and not some other? Is the limit of all computations not a computation? How did this happen?

It says there can be no algorithm that will determine the homomorphy of any two arbitrary compact 4-manifolds. But there is nothing that says the next state can be any arbitrary 4-manifold.

Is the physical universe a purely subjective appearance/ experience for each conscious entity? What is it that shifts from one state to the next? Well that's a crucial question. Bruno assumes that truth implies existence. That makes no sense. Only truth of existential statement entails existence. s(s(s(0))) is prime' entails Ex x is prime So if 1+1=2 is true that implies that 1, +, =, and 2 exist. This is because we assume logic, and P(n) === ExP(x) is an inference rule in first order logic. And this works for 1 and 2, not for + and =, which might exist for different reason, as well defined subsets of the models or as relation at the meta-level or through their Gödel numbers. I think this is a doubtful proposition; particularly when talking about infinities. Even if every number has a successor is true, what existence is implied? Just the non-existence of a number with no successor. 4) What is the cardinality of all computations? Aleph1. From the 1-views (or from the 3-view of the many 1-views).

I can control the probability range that it will happen through the strength of my motive and the clarity of my sense. However, from your point of view, you don't know which version of you you will experience, so your future is indeterminate / random / probabilistic, not deterministic. So you say. How much do you want to bet that I'm going to sleep in my bed tonight? How about for the rest of my life not including vacations? That's a lot of universe where I sleep under a bush or on the roof or in Jellystone Park. There is obviously at least a small probability that you will decide to sleep under a bush tonight. You would have to admit that under your concept of free will, otherwise in a deterministic single universe you would be compelled to sleep in your bed, which I don't have a problem with but you do. In a deterministic multiverse, you will definitely sleep in your bed in most universes (loosely most if they are infinite in number) and definitely sleep under a bush in a few. You can't be sure in which type of universe you will end up in so the future is indeterminate. It's impossible - logically impossible, impossible even if you know every deterministic detail of the multiverse's future history - for you to know which version will be the real you, since all versions have equal claim to being the real you. This is a quite simple, but counterintuitive idea. No I understand the idea completely, I just think it's an obvious plug for the inconsistencies of QM.

It's all phlogiston, libido, elan vital, animal magnetism, etc. It's quite nice in theory, but it sodomizes one side of Occam's Razor with the other.

Whether it's true or not is a separate question but it does allow for your future to be truly indeterminate in a deterministic multiverse. The teleportation thought experiments we often talk about here model this in a simpler way. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups Everything List group.

Quentin Hi Quentin, So could we agree that the idea that the universe is defined/determined ab initio (in the beginning) is refuted by this? I don't know what you mean here... but in comp the universe per se does not exist, it emerges from computations and is not an object by itself (independent of computations). Dear Quentin, My interest is philosophy so I am asking questions in an attempt to learn about peoples ideas. Now I am learning about yours. Your sentence here implies to me that only objects (considered as capable of being separate and isolated from all others) can exist. Only objects exist and not, for example, processes. Is this correct? No, it depends what you mean by existing. When I say in comp the universe per se does not exist, I mean it does not exist ontologically as it emerge from computations. Existence means different thing at different level. Does a table exist ? It depends at which level you describe it. Dear Quentin, I am trying to understand exactly how you think and define words. By exist are you considering capacity of the referent of a word, say table, of being actually experiencing by anyone that might happen to be in its vecinity or otherwise capable of being causally affected by the presence and non-presence of the table? I still don't understand what you mean by the idea that the universe is defined/determined ab initio (in the beginning) is refuted by this. Regards, Quentin Don't worry about that for now. Let us nail down what existence is first. -- Onward!

Existence means different thing at different level. Does a table exist ? It depends at which level you describe it. Dear Quentin, I am trying to understand exactly how you think and define words. By exist Existence is dependent on the level of description, and can be seperated by what exists ontologically and what exists epistemologically. So it depends on the theory you use to define existence. I would favor a theory which would define existence by what can be experienced/observed. Maybe it's a lack of imagination, but I don't know what it would mean for a thing to exist and never be observed/experienced. are you considering capacity of the referent of a word, say table, of being actually experiencing by anyone that might happen to be in its vecinity or otherwise capable of being causally affected by the presence and non-presence of the table?
