Since we're bringing in mathematical isomorphisms between systems (via
the hash function and the game of life), let's consider a simpler
example: differentiating functions. Let S be some finite (though
possibly very large) set of polynomial functions, closed under
differentiation. The derivative is a map from S to itself. Via a hash
function f, this is then seen as an abstract map from f(S) to itself.
Then what? Well, differentiation is connected with multiplication and
addition of functions. We can choose S to be sufficiently rich to have
many examples of this. Via f, we get some complicated relations on
f(S), and differentiation interacts with these relations (similaly,
localness can be phrased in terms of the image of the hash function;
it's just a lot more complicated).
So far, I see no reason to consider that S and f(S) should be treated
differently. Sure its more complicated in f(S), but consciousness is
I see only two ways of distinguishing S and f(S), and the equivalents
in the game of life: 1) The question asked and 2) The implicit
1) The question asked.
When you ask "what is the derivative of this function", you are not
asking the equivalent (but hideously complicated) version in f(S). In
fact that hideously complicated question has no meaning unless we know
its simple equivalent. Similalrly, when we ask "what is
consciousness", we expect the answer to have meaning, while the hash
function equivalent is meaningless.
We can even formalise what we mean by meaning. "What is consciousness"
is a complicated question, but we know the outlines of the answer (and
it is not: the average wavelength of the light hitting Io during a
solar flare). The answer, whatever it is, will have simpler, quasi
answers - incomplete but informative. The has function equivalents
will not be simpler than the hash function equivalent to the full
2) The implicit infinity.
Implicit in the definition of differentiation is the fact that we
could differentiate any polynomial (with, say, rational coefficients).
The definition of differentiation to f(S) does not extend to infinity
in this way; in fact, there is no evident extention of f(S).
So our definition of "differentiation" somehow covers an infinite
amount of cases, though it is defined finitely. A GLUT could not do
