But here Clark contradicts all the textbook on the subject. In fact all what John Clarks says here is that you cannot get a physical object from an arithmetical computations, which is trivial, but does not prove the existence of the physical object, as physical is a relative relational notion in arithmetic.
Those type of argument are only the usual knocking on the table.

Which is very good evidence for the existence of a physical object.

But it is no evidence at all about the ontological status of such object

It's ontological state is "exists". Bruno wrote above, "...does not prove the existence of the physical object, as physical is a relative relational notion in arithmetic." My point is that you don't have prove the existence of physical objects from Peano's axioms - there's much stronger evidence readily available.


No, that is evidence for stable information pattern. It is at best evidence for a sharable dream. And we want explain that stability without invoking a mysterious ontologically prior matter. We want extract its appearance by the computations which solves the measure problem. Step 8 does not give much choice. using ostentation works in physics, not in metaphysics, except to test the physical part of some metaphysics in which physics is explained. With comp, I don't see any other way to explain a relation between what we are conscious of and consciousness.

... so what is it for ? Computationalism, MWI, do not deny the existence of physical objects... even subjective idealism does not deny you interact with physical object, it is the reality/ ontological status of those which is questioned... so what's the point to use such argument ?
