Yes, but then you get the debate if the “last cut” is made by consciousness (Wigner, von Neumann), or is it in the device instruments and macro-world (Prigogine), plus the problem of the FTL if you want one and only one world, etc. With mechanism, things get far clearer: all you have is very elementary arithmetic, and the physical is given by the observable mode of the universal machine (which exists as a consequence of the laws of addition and multiplication). The observable are determined by the “probability 1”, which can be translated in arithmetic by []p & <>t. We lost transitivity which is nice for the immediate apprehension, and we get a quantum logic with a sharable part (quanta) and a non sharable part (qualia). It is motivated by the UDA that we can get observation only through 1) The Sigma_1 sentences p (the arithmetical description of the leaves of the universal dovetailer, or what you can access through very elementary arithmetic (cf sigma_1 completeness = Turing universal). 2) which are true (or false in some sense) in all accessible world, in arithmetic: []p, and 3) repeatable, avoiding the cul-de-sac world condition, in arithmetic <>p. Three arithmetical and quasi-arithmetic modes satisfies this requirement: []p & p (not arithmetical, non definable by the machine concerned, but “bettable”), []p & <>t, and []p & <>t & p. To be sure there is an infinity of them, conferring to them a graded structure, which is also welcome here. They all, at the G* (true) level provides a quantum logic, and the tree of them are different, and richer than most quantum logics isolated by physicist and logicians. The richness comes from the Löb’s formula, which encapsulate the self-reference implicit in all observation (the fingers, with the sign minus points on the observer). It would already be interesting to see which of the quantum logics is closer to the empirical one. If empirical-physics is closer to []p & p, then Plotinus is more right than my own intuition or taste, and the physical is more psychological than material in the phenomenology. If empirical-physics is closer to []p & <>t, then the separation between subjective and objective is less subjective, and the sigma_1 sentences looks like “primary matter”, and that is what I expect. If empirical-physics is closer to []p & <>t & p, then we get a curious mix of both, the physical would rely On an epistemic intuitionist quantum logic. The incompleteness divides those modes on the true and assertable part of the self-discovery. Theology contains many true but not assertable propositions. There is a notion of blasphemy, and it does not send the machine into hell, but it can transform its location paradise into local hell. It is all in the head of the universal numbers. Necessarily so once we assume mechanism explicitly, which is made possible by the Church-Turing Thesis.
