Hi Stephen:

What I am basically saying is that you can not define a thing without
simultaneously defining another thing that consists of all that is "left
over" in the ensemble of building blocks. I suspect that usually the "left
over" thing is of little practical use.

However, this duality also applies to the "Nothing" and its left over which
is the "Everything". A look at this pair allows the derivation that the
boundary between them [the definition pair] can be represented as a
"normal" real and can not be a constant if zero info is to be maintained.

Thus, given the dynamic, this boundary's representation as I said in the
last post can be modeled as the output of a computer with an infinite
number of asynchronous multiprocessors. A cellular automaton with
asynchronous cells. Universes are interpretations of this output.

Sort of a left wing proof that we are "in" a massive computer.

The Hintikka material you pointed me to is far too imbedded in mathematical
language symbols for me to understand.
