Re: [asa] TE/EC Response

While this evolution-perspective may be the case with many TEs, it is
not so for all. The TE position you describe is pretty much anchored to
the idea that man, in the form and function as we know it, is the single
and singularly purposed product of the evolutionary processes. That
requires that either God aimed the evolutionary gun at that target, or
guided the bullet directly, or influenced the ambient of the
bullet-in-flight so as to gently(?) guide the bullet to its human-state
target. One other posit is imply that God is "outside of time" (whatever
that means) and therefore has some other means of determining the
evolutionary trajectory such that we humans are the Creational culmination.

Thoese notions seem to be collectively guided by the uniqueness-of-man
perspective, and man-as-the-ultimate-objective of Creation understanding
(all referenced to humans as we know them). But there are some who would
suggest that these notions may ultimately be as quaint as geocentrism
and flat earth, noting for example that we humans don't seem to be at
the center of the known universe as would seem to be consonant with this
creational-objective perspective.

Instead, a Fully Gifted Creation (to use Howard Van Til's language)
could proceed in reasonable harmony even with the Darwin understanding
of evolution, by simply removing the constraint that the functioning of
the universe must by design and/or intent arrive at a sole preconceived
solution in the form of humanity. In other words, it could evidently
proceed constructively, productively and interestingly without the
specifically human form and function (and direction) "in mind" in any way.

Why require that all this "choice" and randomness and hugeness converge
on just one state solution? Why all the fuss and bother to move all over
the state map to get to just one particular and quite unlikely terminal
state? Why not just "poof" it all into existence without all the spatial
and temporal dynamics that seem to characterize our being and ambience
(as some of our more literalist brethren would prefer)?

The more I think about it, the more incredulous it seems to me that the
whole of this mind-bogglingly immense Creation is for the sole purpose
of accommodating a single trajectory to a singular "solution", ...man.
It seems excruciatingly limiting (and egotistical) to constrain the
intent of God in this particular way, though it admittedly puts a strain
on our imagination to think about the alternative(s). It is humbling too
to think that there might be/have been/may be other sentient creatures
elsewhere, who may similarly arrive at the "who" and "why" questions
about being.

Now, I am not arguing that this is the way it is. And I respect your use
of "most". My intent is just to point out that as with other labels,
there is a tendency to unduly narrow the reality that is collected for
convenience under a label such as TE.
