The problem is doing anything in the first place. Computations don't
do anything at all. The reason that we do things is that we are not
computations. We use computations. We can program things, but we
can't thing programs without something to thing them with. This is a
fatal flaw. If Platonia exists, it makes no sense for anything other
than Platonia to exist. It would be redundant to go through the
formality of executing any function is already executed non-locally.
Why 'do' anything?
Bruno can 't answer that question. He is afraid that it will
Not at all, the answer is easy here. In the big picture, that is
arithmetic, nothing is done. The computations are already "done" in
it. "doing things" is a relative internal notion coming from the first
Also, Platonia does not really exist, nor God, as existence is what
belongs to Platonia. Comp follows Plotinus on this, both God and
Matter does not belong to the category exist (ontologically). They are
OK, but you are ignoring my question: How does the existence become
decomposed such that there are "epistemological beings"? So far your
explanation is focused on the representation in terms of arithmetics and
I accept your reasonings: In the big picture, that is arithmetic,
nothing is done." There is no "action", no change, all that exists "just
is". But then what do we make of time? We can dismiss it as an illusion?
But that would be just an evasion of the obvious question: Why does the
I am interested in explanation that at least try to answer this
question: How does the illusion persist? What might "cause" it? Why do
"special purpose" computations occur such that we can identify physical
systems with them? My proposal is to weaken the concept of Computational
Universality a tiny bit and thus allow room for the possibility of an
answer to the questions that I have.
Consider this: What happens is there does *not* exist any physical
system that can implement a particular computation X? Is it possible for
us, humans, or any other sentient physical being to "know" anything
about X, such that we might have some model of X that is faithfully
