    I'm not entirely sure that the points of view being advocated
    or criticized have necessarily been fully defined. I see at
    least four options relating to "natural" versus ID
    explanations (with plenty of intergrades):

    1. Everything must have a "natural" explanation.

    2. "Natural" explanations seem to work pretty well and
    provide an adequate proximal explanation of the creation of
    organisms.

    3. "Natural" explanations do not seem adequate.

    4. There must be physical evidence pointing to
    non-"natural" events. God is more involved in them than in
    natural events.

    The first and last are philosophical positions and are major
    targets of criticism from the other side. Also, people
    holding the second or third views may be accused of the
    first or fourth. This is incorrect. For example, I think that it
    is theologically likely that the physical acts of creation of
    organisms used ordinary means throughout, and I do not
    see any physical evidence as disproving that. The popular
    ID use of bad counterexamples, such as the mitochondrial
    genetic code argument, makes me further dubious about
    the merits of purporedly irreducible events. However,
    endorsement by Dawkins is likewise detrimental to
    credibility for me.

    Both 1 and 4 assert that God must have done things a
    particular way (if He is involved), whereas 2 and 3 suggest
    that He did things a particular way.

    Of course, based on a general level of success or failure of
    a particular approach, one might reasonably put more
    initial credence to an explanation that fits that approach. It
    is the a priori ruling out of a possibility that is inherently
    philosophical rather than observational (not that we are
    perfectly obsevational in other cases, just more so).
