The material qualities of matter are all the results of rules (which are ultimately determined by the properties of the mathematical object an observer happens to find themselves in). With computationalism, the exact mathematical object an observer happens to exist in cannot be definitively determined or predicted. Rather it might be said the observer simultaneously exists in all of them (all mathematical structures which contain that observer's mind). This is confirmed by quantum mechanics. When you measure the state of a particle, the result is unpredictable because one cannot know in which universe they will be at the time the the result is observed. > Would that mean that in all possible > universes a proton is a proton and 79 protons is gold?

Varying these parameters results in universes with entirely different physics and chemistry. For example, physicists have discovered no good reason why the fine structure constant has the value it does. > > On Jul 21, 2:03 pm, Jason Resch <[email protected]> wrote: > > On Thu, Jul 21, 2011 at 10:54 AM, meekerdb <[email protected]> wrote: > > > On 7/21/2011 2:27 AM, Bruno Marchal wrote: > > > > >> Axiomatics are already in Platonia so of course that forces > computation > > >>> to be there. > > > > >> The computations are concrete relations. > > > > > If the are concrete then we should be able to point to them. > > > > If your mind is a computer, you don't even need to point to them, > everything > > you see and experience is direct evidence of the existence of the > > computation implementing your mind. > > > > Also, I don't think the "point test" works for everything that has a > > concrete existence.
