Neil Lion:Seeing that there is no rigerous way to define what

make any sense to say my desktop computer has become conscious?
Bruno:Your desktop computer cannot be conscious, nor can my brain.
If you succeed putting my mind (software) in your desktop
computer, your desktop computer will still not be conscious, but
it will make possible for me to talk with you (as my brain does
now). Only a person can be said conscious. And person, like
nation, or game are immaterial (with comp), and not absolutely
singularisable (only relatively).
Brent:This confuses me, Bruno. You always postulate 'comp', i.e. that
the brain can be emulated. I had always assumed that this entailed
the emulation being conscious.
Well, not really the emulation, but some person can have
a consciousness such that that consciousness is manifested
through that emulation relatively to you, or relatively
to the computations you share with that consciousness.
Now I see that you regard consciousness as not only as immaterial (as
a computer program or mathematics is immaterial) but also independent
of material - a soul - and at the same time you regard the material
as independent of consciousness so that a material structure, such as
a brain, can have related consciousness or not. This seems to be
dualism - which as you must know has many problems related to the
interaction of spirit and material.
I do not regard the material as independent of consciousness.
Remember that the material is a consciousness construction
in the company of those computations going through that consciousness.
It is true that, locally, a piece of matter can be considered as
independent of my consciousness, but it is just a way of speaking.
I agree with you that dualism is difficult to defend, but comp
entails immaterialist monism. Now, we can bet, for empirical
reasons, that we are sharing long and deep computations, which
are also interfering (for pure computational reasons but we
can expect that quantum interferences mirror the comp interferences),
so that some very stable object appears in our experiences, and can
be considered as mind independent for all practical purposes.
Nevertheless any proposition like that object exists is a
machine anticipation true only relatively to a most probable
computation.
OK, as I understand your ontology it is something like:
mathematics-computation-consciousness-material
But this seems to still leave the problems of dualism because it allows
that a consciousness (e.g. mine) can be generated without any
associated material (e.g. a brain) and also that consciousnesses can
generate another brain (e.g. duplicate of mine) with no associated
consciousness. I take it that this is the 'indeterminism' you
illustrate by the Washington/Moscom duplication experiment. I had
never been able to understand what indeterminism you referred to until
now. Now I see that you suppose that the original consciousness will
go into one of the duplicates and the other will be void of
consciousness. Is this correct?
