Hi Bruno Marchal Every great discovery of man (even in logic and mathematics)started as a possibility (an insight, conjecture, an intuition, ahypothesis )in the mind of a man. The transistor, the basis of the computer,startedas a possibility. I offer this as a confirmation of Lucas and Penrose.

The mind, at least in practice, is far superior to any computer. For there are infinite possibilities.

Universal machine have infinite possibilities too. Bruno

"I can't think of an arithmetic example that LP could use, whichthey should have provided.So as the question is posed, LP seem to be mistaken or at leastincomplete themselves.Gödel talk about axiomatic logical theories, or machine, theoremprover. It shows that for such theories or machine, we can find truestatement that the machine or theory cannot prove.But the reason why Penrose and Lucas is based on the fact that Gödelprovide an algorithm for finding that true but non provableproposition. So machines excel in finding the true proposition aboutother little machine, that the little machine cannot find.Löbian machine can prove theorem own Gödel's theorem, and developtransfinite autonomous self-extension in provability matter. G andG* remains correct at each state, and Becklemishev has foundextension of G and G* formalizing the multimodal logic captureingthe [] = [0] and the [alpha] transfinite provability level.(But you need to study logic for making sense of this).At any rate, many factual statements can obviously be true butunproveableby a computer alone. That the sky is blue would be such a statement.OK. We are not "obviously" more gifted than the computer.Or any piece of data not in its data bank.No, the computer can assert much more than what is in the data bank.Much much more. What it deduces from it, what it induces from it,and all the hazardous theories, if not the lie and delusion etc.Look at the difference between the string "z_n := (z_(n-1))^2 +1",which is the data bank content, and what the universal machine saysfrom that :https://www.youtube.com/watch?v=G0nmVUU_7IQSo I conclude that LP are correct at least for most factualstatementsand they only needed one example.?No LP are not correct. They can do what they pretend on simplermachine than themselves, and machines can do that too. But theycannot do that for themselves without changing themselves, and themachine can do that too. The machine already knows that it is a bitrisky.

The simpler form is the Lucas argument, discussed in great scholarly detail on http://www.iep.utm.edu/lp-argue/To be franc there is nothing new in that paper, on the contrary itfails to mention the work done by Webb (not to talk on mine onLucas, Benacerraf and the Penrose argument).I have counted more than 50 errors in Lucas paper. Some areuninteresting, and some are very interesting. The argument of Lucasand Penrose are typically invalid, but it can be corrected, and itleads to the proposition according to whioch:If I am a machine, then I cannot know which machine I am, and thisplays some role in the formal part of the study of the first personindeterminacy.Lucas and Penrose assumes that they are sound, and that they knowthat they are sound, but this is already inconsistent, even if thesoundness is restricted to arithmetic.In Conscience & Mechanism, I show how all Löbian machines canrefute Lucas and Penrose. Basically they confuse []p (3p beliefs)with []p & p (1p knowledge)..It seems to me to be self-evident that 1p cannot be part of 3pBut that is good insight of you. For correct machine, this can beproved, as the machine cannot prove the true equivalence between[]p and []p & p, as they don't know that they are correct.[]p can be defined in the language of the universal machine, but[]p and p cannot. By assuming correctness of some other machine,the Löbian one can prove that for simpler machine than themselves,and they can bet on their correctness and lift that idea at theirown level, with the usual theological risk of this(forgetting the "bet" in the process).Which seems to be a equivalent to Godels's theorm.OK, but invalid when used to pretend that we are not machine, likeGodel and Lucas did.Or the observer can't be part of what is observed. Or more generally, the prover cannot be part of the proof.Well, both the observer (3p) and the prover (3p) can do that,without necessarily knwoing that they do that.But the knower (1p) cannot.To explain the details of this would need more familiarity inlogic, and notably Solovay's theorems, which I might explain someday.Bruno[Roger Clough], [rclo...@verizon.net] 11/21/2012 "Forever is a long time, especially near the end." -Woody Allen ----- Receiving the following content ----- From: Bruno Marchal Receiver: everything-list Time: 2012-11-20, 10:05:13Subject: Re: Reality Check: You Are Not a Computer Simulation[Audio]On 20 Nov 2012, at 14:51, Roger Clough wrote:Hi Bruno Marchal Sorry, where are the steps of UD ?You can find them here: http://iridia.ulb.ac.be/~marchal/publications/SANE2004MARCHALAbstract.htmlYou can download the PDF, and also the unique slide with a diagramfor each step, as this can help to remember them.

This does NOT mean that a computer create theconsciousness. It means only that the consciousness can only bemade manifestable through relative bodies, but it exists only inPlatonia. But then matter too, and it relies statistically on allcomputations going through my current comp states, and the mathshows that this will include some continuous/analog observable.I am not sure this can be understood without getting a personalunderstanding of at least the first seven step of the UD reasoning.Bruno[Roger Clough], [rclo...@verizon.net] 11/19/2012 "Forever is a long time, especially near the end." -Woody Allen ----- Receiving the following content ----- From: Bruno Marchal Receiver: everything-list Time: 2012-11-18, 07:46:20Subject: Re: Reality Check: You Are Not a Computer Simulation[Audio]On 17 Nov 2012, at 22:25, meekerdb wrote: > > > -------- Original Message -------- > >> >> More In This Article >> * Overview >> _Is Quantum Reality Analog after All?_ >> (http://www.scientificamerican.com/article.cfm?id=is-quantum-reality-analog-after-all >> ) >> >> >> >> Conventional wisdom says that quantum mechanics is a theory of>> discreteness, describing a world of irreducible buildingblocks.>> It stands to reason >> that computersÿÿwhich process information in discrete >> chunksÿÿshould be able>> to simulate nature fully, at least in principle.

As I have ofteninsisteddigital physics (the world can be fully be Turing emulated)violatedthe consequence of comp which makes necessary the presence of non computable observable, and even non enumerable spectra. Digital physics is self-contradictory. It implies comp, but comp implies the negation of digital physics, so, with or without comp, digital physics is contradictory.
