But arithmetical structure are enough (or please mention a flaw in UDA). [SPK] Please reread my last post.

We need a physical world. No doubt on this. The point is that we don't need a primary physical world. [SPK] I am not claiming that the physical world is primary! But I am claiming that the number world is not primary either! Both the Ideal and the Physical emerge simultaneously from the Nothing as dual aspects. > otherwise we will be trapped in the UD in endless > Poincare recursions. This is the nightmare that Nietzsche saw. [BM]I doubt this, but if that were true, that would not been a reason to abandon comp. Only a reason to hope that comp is false. But comp is not yet sufficiently developed to start having premature fear of it. [SPK] Unless there is something that acts as a limit on the expressions of the UD then how do we recover inertia? > >>> Oh well, that is your choice, >> >> I am problem driven. I don't make choice. >> > > [SPK] You are choosing to not consider multiple interacting minds. [BM]Why do you say so? comp starts from the interaction between a patient and its doctor. Comp is an hypothesis. If it leads to solipsism, that would be a reason to abandon it, indeed. But everything points on the fact that there is all the room needed for mind interaction, and even that this is what stabilizes the first person plural in the long run. [SPK] Again, the "interaction" that occurs between patient and doctor is symmetrical and (maybe) commutative, but this does not allow the representation of true concurrency. The Doctor could be purely a construct of the patient's mind, nothing prevents this! Where we consider a situation of many separate minds having to simulate each other's 1p then one can see the issue that I am considering. We need a notion of "space" to allow for a variation of minds so that one can have a situation where two identical minds can have different locations relative to a third and thus be different minds. There is no topology in pure logic, thus we need the Stone and Pontryagin dualities to link logic and topology. Logic tells minds how to think, Topology tells minds how to differ. We need both, not just one or the other. > So > far I have only seen discussions in your papers in terms of > "interviews" between different logics. [BM]There is an 'interview' between a human (you and/or me) and a universal machine. The logics are related by representation theorems, as usual. [SPK] Yes, I understand that, but that same interview can be reproduced in the case where the Universal machine is generating a simulation of a human and a doctor having a conversation, but only if we assume that the Doctor and the human have 1p experiences of the event. The fact that the simulation has the identical information content that a 3rd person would experience that was an invisible man in the doctor's office does not require that the invisible man is real or his supposed experiences actual. We are conflating the act of writing down the expressions of theorems with the existence of the signified of those theorems if we do not distinguish between signified and interpretant. I invite you to read a good book on Semiotics. The Theory of Semiotics by Umberto Ecco is good. http://en.wikipedia.org/wiki/Semiotics and http://en.wikipedia.org/wiki/Semiotic_elements_and_classes_of_signs_%28Peirce%29 to start. > What you are calling > interviews, I would call them interpretations or mappings. [BM]"interview" just means that I am in front of the machine, and I have to ask her about each different points of view. I just translate the usual classical theory of knowledge in terms that the machine can understand. So of course, we are lead to mappings and representations. [SPK] See previous. No, you are not "in front of the machine." You are following an algorithm to derive expressions of a logic via the manipulation of its symbols following the rules of it grammar. There is nothing in a logic that can encode differences in topological points of view (diffeomorphisms between manifolds) unless one uses the duality that I have mentioned, thus I claim that we need this duality. > There is no > notion of separable entities having anything like what you and I are > doing right now here. [BM]You are not at the right level. You could criticize string theory because it does not bring you a pizza at home tonight. [SPK] No, I criticize string theorists that do not understand what it is that they are thinking about. [BM]The interaction comes from the linear combinatory algebra. But if I posit at the start, I will lose the qualia. I have to derive that linear algebra from the gluing property of the machine dreams (UDA shows we don't have choice in that matter). If eventually the machine dreams does not glue well enough, we will know that comp is false, with some degree. [SPK] Bisimulation is the glue between separate 1p. It allows us to recover diffeomorphisms in the continuum limit on the topologies but unless we have a means to define the delta-epsilonics and the Hausdorff property we cannot do this. http://mathprelims.wordpress.com/2009/02/22/the-hausdorff-property/ > You wrote brilliantly about your idea of > interviews here > http://www.mail-archive.com/everything-list@googlegroups.com/msg08457.html > But I will continue to argue that "the logic of arithmetical self- > reference" is not an exchange of information between separate minds. [BM]It is not supposed to be that. The logic of Bp & Dp should bring such a thing, or, if you can prove it prevents such exchanges, then comp +Theaetetus is refuted. [SPK] I am not trying to refute comp or Theaetetus or comp + Theaetetus! I am just trying to argue that comp + Theaetetus is insufficient to model multiple separate 1p interactions, i. e. true concurrency. > It is at most the exploration of 1p aspect of a logic by that logic. > It is solipsism at its most exquisite form. (Please understand that > this is not a bad thing, solipsism is thinking and dreaming about > one's thoughts in a closed and convex form). [BM]It is not solipsism-the philosophy. Bp & p, and Bp & Dp & p, leads to "lived solipsism", which is the case for the first person internal experiences. But the modality without "& p" are not solipsist at all. You are conflating different modalities. [SPK] Read what I wrote again, please. Unless we have multiple separate 1p that can have something that is like experiences of interacting with each other in a way that is irreducible to the computation of a single classical computation then something is obviously missing. I am arguing that we need bother multiple quantum systems (logics and topos in each) that can act to constrain each others possible experiences so that a world like that we experience can obtain. > > But there is something else that troubles me even more. > snip> > The problem is that "the set of all true arithmetical sentences" is > a very narrow, but deep, interpretation of the One. How can I define > such things as Zeno's paradox and its solution, for example? [BM]It is basically solved at the start, because real numbers are epistemological, or meta, construction. Comp suggests that the ontology is discrete, because we can explain the beliefs and uses of the rest from that. [SPK] I understand that one can generate an arbitrary approximation of a Real number by running a computation based on N to N maps, but this is not the same as claiming that only the Integers exist! Comp only works because there are physical systems that can implement the computations, just as you are able to have "interviews" with logics because you can write symbols and manipulate them on your chalk board (or equivalent)! > There is > no way to define an infinitesimal or a derivative that I can find. [BM]Because comp makes the real numbers a simplification, and it makes calculus a handy tool for manipulating big numbers and and epistemological mind constructs. Analysis and physics are epistemology. This follows from UDA + some amount of Occam. [SPK] I wish that you might spend a week trying to solve the equations of motion of 3 bodies mutually gravitating then come back and repeat that claim! > How > do I recover the calculus? [BM]In the stable numbers' dream. [SPK] And unless there are many separate dreamers then one is back the to the pathological solipsism problem. The fungibility of numbers causes this, unless on has a topology to differentiate the different dreamers then the is only one dreamer. > Your model has no expressions that can be > used to act as a clock... [BM] I told you that the definition of integers *is* a clock. Arithmetic starts from a clock. And besides, I have no model. Only a theory (that I am digitalizable at some level, yes doctor + CT). [SPK] NO! A clock requires at least one aspect of change, a scale to parameterize the change and a comparator between the change and the scale. Numbers alone will not do, at most they can act as labels on the scale. See my further comments on time below. > Thus it is no surprise that the whole > structure is frozen. [BM]The point is that after Gödel, nothing is more dynamical than Platonia, when seen by the creature defined internally in Platonia. If you assume a real fundamental time, you have just to abandon comp (and special relativity which makes time an illusion too). Anyway, time and space are things which I prefer to search an explanation for, than assuming them at the start. [SPK] Oh my! No, Gödel (and Post, Turing, etc.) could have never accomplished anything without the prior distinctions between signified, signifier and interpretant. > There is no room in it for the idea of evolution, > nothing 'becomes". [BM] When the UD is executed, all the becoming becomes. And so all possible evolutions develop. You could as well criticize SR and GR, and QM (without collapse). I mean, this is a place where comp already agree with most physicists, except Prigogine. [SPK] But Bruuno, my point is that (assuming your ideas) the UD is eternally “running” so there is no “when the UD is executed” as distinguished from “when the UD is not running”! But this does not address the concurrency problem it merely claims that all simulations exist. existence is not actual. Existence is property indefinite and context free. Actual 1p are contextual and locally determinate. > Everything just "is". [BM]Only in God's eye. [SPK] The idea of an anthropomophic God is oxymoronic. There is no “observer” or interpretant outside of existence. > Every fiber of my being > screams out in revulsion at this! [BM]There is no reason, but apart from solipsism, we cannot use such affirmation as an argument. You could say that Energy is not equal to mc^2 because we can do horrible bombs with that idea. [SPK] You know that I would not think or make claims that way... Please do not insult my intelligence, however feeble and addled by age it may be. > I am not a Σ1 sentence! [BM]I guess you mean: my mental state is not UD-accessible. Just say "no" to the digitalist surgeon, Stephen. I don't know if that is true or not. My point is that if it is true, then physics is a branch of number theory, and I show how time space and physics can indeed to be retrieve. There is already subjective duration, but not yet space. [SPK] No, I will not say “no”! You are missing my signified completely here. My claim is that number theory requires topology to be expressive and concurrent. So alone it is insufficient. [BM]We would disagree only if you want both - a fundamental basic *primary* time, and - saying yes to the doctor. OK? [SPK] NO, I DO NOT WANT A BASIC PRIMARY TIME!!!!! DO you actually try to understand these words? Let me see if I can find the French translation. Le temps absolu n'existe pas. I am arguing for a local notion of time, based upon the work of Hitoshi Kitada. See: http://kims.ms.u-tokyo.ac.jp/doc/time_V.pdf and http://kims.ms.u-tokyo.ac.jp/doc/time_XI.pdf (These have a lot less math than his other papers.) snip >> It is more correct to say that the first person defines it, and is >> itself defined by number relations. >> > > [SPK] OK, but the numbers can code noise just as they can code the > content of my 1p in this moment as I type this post.

[BM]My point is not that it is true, but that it is a consequence of the comp hyp. If you can show that 'something is wrong', then you refute comp. [SPK] No, I do not wish to refute comp. I am OK with comp. I am just saying that comp is incomplete even if we add AR. > The fact that we can represent a history of events as a sequential > narrative is OK, but this is not time.

At the same time you can see GR as the science of time. You are confusing God's point of view, with the relative points of view of the "terrestrial" beings. [SPK] It is abundantly clear to all that care to investigate that there is no “God’s point of view” except as an absract idea in a finite mind, nor is there an absolute ordering of events (Newton’s absolute time.) I am argue FOR a notion of local time as had by the points of view of the "terrestrial" beings. How you keep not understanding this amazes, confuses and frustrates me! Le temps absolu n'existe pas. Le temps absolu n'existe pas. Le temps absolu n'existe pas. snip > > [SPK] OK, but please try to understand what I am trying to > communicate.

[BM]Probabilities are relative to states, themselves relative to histories/ computation. Your question is meaningless. I'm afraid. [SPK] Can you distinguish between orderings and differentiations? If you cannot then I am trying to talk to a brick. Silly me! > >>> To the UD everything is simultaneously given.

[BM]There is an infinity of UDs. But they reflect each other in a way which makes them equivalent ontologically. They have the same internal epistemologies. That is why we have to recover quantum computation from number theory. [SPK] And how are they seperable in the Hausdorff sense? http://mathprelims.wordpress.com/2009/02/22/the-hausdorff-property/ http://en.wikipedia.org/wiki/Seperable_space > We need a local > version of the axiom of choice that does not lead to Banach-Tarski > paradox.

Note that Wegner says many things "against CT", which I believe is true in the comp-physics, but irrelevant for the problem of deriving physics from numbers. [SPK] If we are only trying to derive the physics of the 1p of a single entity we can do that easily from numbers, you have demonstrated that already, but if you are trying to derive the physics of many separate 1p then you must include topology. snip > [SPK] Could you elaborate on this bisimulation? [BM]The B of the logic Z can be define in G by Bp & Dt, and the D of Z, by Bf v Dp (the D of Z is really the usual logican's notion of relative consistency). Vandenbussche found that you can dually reverse that translation: the B of G can be defined in Z by Bp v Df, and the D of G can be defined in Z by Dp & Bt. Be careful to interpret the B and D in the right logic. I should perhaps write this in the following less ambiguous (but less readable) way: B_z A == B_g A & D_g t D_z A == D_g A v B_g f B_g A == B_z A v D_z f D_g A == D_z A & B_z t The two lines above are the usual definition of the Z box (the second follows by duality on Bp & Dt) The two last lines are Vandenbussche inversion. It leads toward an axiomatization of Z, Z1, Z* and Z1*. So despite their very different semantics, and "hypostasic role", G and Z are variants of each other. The same for G1 and Z1, G1* and Z1*. Unfortunately there is no such transformation available for the logics X. (X, X1, X*, X1*) We conjecture that G and X are not bisimulable, nor probably S4Grz and X. [SPK] I will have to study this further. My intuition is that bisimulation must occur between multiple versions of logics for my idea to work. So this presents a potential falsification. Good!
