Stathis, my imagination does not run that high. If I imagine myself as an alien scientist, I would be self centered (pretentious?) enough to imagine that I know more about those stupid humans and don't have to experiment on computer - THEN on the real stuff, to LEARN how they are. I would know. I

Hi Bruno So you can see that comp, as defined in sane04, is a weaker version of CTM. (And thus all consequences of comp are inherit by CTM). Certainly it is clear that your /yes doctor/ hypothesis subsumes CTM. But since it is a broader proposition, I fail to see why "all consequences of co

Hi Bruno The first seven steps of UDA makes the following points: 1) that comp entails the existence of first person indeterminacy in a deterministic context. Step 1-3. This is an original result that I published in 1988 (although I made a dozen of conference on this in the seventies). Many

Peter, Everything is fine. You should understand the reasoning by using only the formal definition of "arithmetical realism", which is that a machine is arithmetical realist if she believes in the axiom of elementary arithmetic *with* (the realist part) the principle of the third excluded

A collapse aside

An aside, concerning what actually requires simulation / arithmetic explanation. The algorithm of the collapse dynamics itself operates in a domain meta to the physical, and in this regard there is a reversal of causality with respect to the physical and the arithmetic. But I don't think this

How do you define the relative point of view? Do you know Gödel's provability predicate? The points of view are defined by intensional variants of the current provability predicate of the machine with or without some oracle. There are 8 basic points of view p (truth), Bp (provability/belie
