Whew! Read this quickly. I love an engaging discussion like this.

Ok, Ted, I know you said slow down, but I'd like to just toss out two quick
things for the record.

Timeaus, you said: Now, to refer my argument to TE, I am also saying that
most TEs seem to believe that Darwinian mechanisms are sufficient causally.

I respond: I still see a disconnect here arising from the use of the word

Timeaus said: The idea that something could be metaphysically true and
scientifically false, or vice versa, is typical of the soul-destroying,
culture-destroying dualisms that have plagued the modern world since
Descartes. There is only one world, not two; there is only one "nature",
not two; there is only one "human nature", not two. If evolution shows us
that we IN FACT arose by accident, REAL accident, then we have a conflict.

I respond: Well, perhaps you think I sound like Descartes -- but I think
you sound like Hume, Mill and other phenomenalists. Your assumption that
"evolutionary science" could *prove* metaphysical chance makes no sense to
me. It can't! There is one Reality (not one "world"), but that Reality is
multi-layered. It includes, most basically, God, who is not material and
not of the created "world." It includes, according to scripture, a
"spiritual" realm of personal beings and forces that are not part of our
material "world." Demonstrating an apparently closed causal loop in
space-time does NOT elide divine causation. Wouldn't you agree?

Personally, I am trying to get past both dualism and phenomenalism (and past
both foundationalism and postmodernism), and I see critical realism as a
good avenue in this regard. Ironically, I think critical realism is a
better defense against metaphysical naturalism, and is more Biblical, than
the flat phenomenalist metaphysic you seem to be adopting here. For more,
see Roy Bhaskar's work, Alister McGrath's "Scientific Theology", Christopher
Kaiser's "Toward a Theology of Scientific Endeavor," or my paper on critical
realism and information technology: I would also
preliminarily suggest that the multi-layered metaphysic of critical realism
is consistent with some excellent thinking in the Reformed tradition,
particularly that of Herman Dooyeweerd.

None of this is to say that Darwinian mechanisms *must* be true. I have
read popularizations of Denton but not Denton himself, I confess. I will
make up for that gap.
