I sense hostility in several places below. What changed your intentions?

Looks like you didn't want the truce to extend beyond Christmas season after all.

They affect our *understanding* of our universe by giving a
concrete meaning to the probability that a given universe of the multiverse
is hospitable to any kind of life.
There is a potential infinity of them in Linde's "perpetual inflation" hypothesis,
with no reason to think that *any* of the six "blueprint" constants is the same
in any but a vanishingly small percentage of them. Ironically, you would add MORE
to the list of six that anti-ID zealots have to take into account:

Stephen M. Barr adds a few more ingredients in _Modern_Physics_and_Ancient_Faith_.
But your hostile preceding paragraph suggests that you don't want to hear about them.

Stephen M. Barr does talk about the latter ratio [*op* *cit* pp. 125-126].
It goes by the name of "the fine structure constant".

I wasn't insulting YOU, I was insulting the last sentence you had written.
I would have expected you to say something like this in reply
to the following, but you breezed past it as though it weren't there:
[repeated from above]

But thanks for letting everyone know what utter contempt you
have for Ron Dean. How does it compare with your contempt
for Glenn -- or me, for that matter?

What vein? Are you completely ignoring the physics I've been writing about?

Think of how the following scenario sheds light
on the richness of one of the outcomes.
Suppose that, in a given hour, ten thousand people in the world
are flipping coins to see how long a "run" of one side they can
attain. Suppose one of them flips 30 heads in a row.
Before he gets to 30, don't you think anyone watching him would
become suspicious that he is flipping a 2-headed coin?
After all, the odds against him getting 30 in a row are more than a quadrillion to one.
In fact, it would be unusual to have even 20 in a row (ca. million to one odds)
in such a small sample of coin-flippers.
Yet, the odds against a universe bearing intelligent life are far worse
than quadrillion to one, unless the ranges and distributions are
tremendously loaded in favor of life. Lacking any evidence of such
loading, only a huge sample, in the form of a multiverse would take care of Hoyle's
suspicions that our universe is "a put-up job."

The ball is in your court to defend this polemical sentence against my analogy.
