OK. I was thinking of systems with a complexity of arithmetic and above. I'll
explain the reason below.

The Nothing is the converse of the Everything (Plenitude). Nothing is like a black
screen. Everything is like a white screen. What they have in common is zero
information. I prefer to think in terms of the Everything axiom than in terms of
the Nothing axiom. The reason is that other conditions you may decide to bring in,
act as constraints that restrict the range of the universe you live in and it's
easier to restrict the Everything than to build on the Nothing. This approach is in
fact partially validated in quantum physics in which any phenomenon which is not
expressly forbidden is compulsory.

Now this being said, starting with the Everything axiom (or Plenitude axiom)  is OK
but not sufficient. You are ignoring the anthropic constraint. If you factor in
this constraint you'll find that the only systems which are acceptable are those
with a complexity equal or greater than arithmetic. Otherwise, conscious thought is
not possible.

I am puzzled by the whole concept of distribution when the number of items is
infinite. As Jacques Mallah has pointed out that the methods of limits should take
care of that. I am still not satisfied. IMO, when the number of items is infinite,
their ordering seems to be an important issue in defining the distribution. Yet how
is this ordering defined without resorting to distribution?

PS. I am still waiting for Bruno's explanation of G*.
