No.  I'm talking about a sort of program/data division - which I recognize is
arbitrary in computer program - but I think may have an analogue in brains.
When I write a simulation of a system of ODEs the time evolution of the ODEs
define the states.  But in the simulation, what actually evolves them is
passing them to another program that takes them and the current state as data
and integrates; thus producing a sequence of states.  When you talk about
isolated OMs, what we are conscious of, I think of them as the states.  They
are what we write into memory; they form the "narrative" of the simulation.
The integrator is like a simulation at a lower level, perhaps at the level of
neurons.  We're not aware of it and in fact many different integration
algorithms could be used with little difference in the outcome (as in the comp
idea of replacing neurons with chips).  But the integrator, even conceived as
an abstract 'machine' in Platonia, is performing a function, connecting
one state to the next.  I'm not denying that you can simulate all this and that
you can take a block universe view of the simulation.  I'm just saying that the
block can't be made of just the conscious parts, the OMs, it needs to include
the unconscious parts that connect the conscious parts.
