I am happy we agree here.

Computation of P is clearly impossible (especially if you include any
possible future knowledge ;-) ). But even if this is impossible, might
it perhaps be possible to estimate a Q > P such that Q < 10^(-150) (or
any other terribly small number)? Such a result would be extremely
We agree as far as P is concerned, but apparently not with respect to
the very much weaker claim about Q.

I don't know, but it might be the maximum possible number of elementary
events in the known universe since the big bang. How else do you want to
bound the unknown number of possible evolution-relevant events?
I don't think we should fault Dembski or other IDers for not specifying
the nature of the action or agent behind ID, as their goal is to first
provide evidence that there (probably) is ID.

As I wrote in my answer to Dick Fischer, the trouble is that those who
just _assume_ the configurational space is chock-full of functionality
will never trouble themselves with any thought of checking this
assumption. "We are here - therefore the spontaneous emergence of any
biological functionality is no problem". As long as they don't see any
problem here, they are not going to investigate these evolutionary
processes at the molecular level, because they assume they already know
the answer, cf. Dawkins.
I am not suggesting that you are guilty of such circular reasoning. In
your case, if I understood you correctly, this assumption is based on
the theological argument of the functional integrity of creation.
However, I feel we should be free to investigate such questions, both on
the scientific side (what Dembski is trying to do), and on the
theological side (which is your concern). Of course, I agree with you
that the two sides should talk to each other, both about the scientific
and the theological questions. Some time ago, I attempted to discuss
these questions with Dembski, but never got an answer from him.
And you know that I feel the functional integrity of creation is
irrelevant to the question of the Creator possibly using "hidden
options". Our job as scientists is to try to find scientific answers
(probabilities...) to questions about the emergence of life, biology,
evolution, etc., without regard to metaphysical convictions like
functional integrity of creation or the scalable back side of Mount
