Thanks, Keith (and all). How would you distinguish divine guidance
generally from discontinuity? At one pole perhaps you have God inserting
fully formed organisms into the tree of life, at the other pole you have God
ensuring that just the right set conditions, mutations, and interactions
occur so that life in all its complexity arises as it has. In either case,
isn't there an insertion of divine agency that results in discontinuity with
what otherwise would have occurred? Is there a philosophical principle that
makes one type of discontinuity more palatable than the other, or is it just
a matter of how the proposed types of discontinuity match the observable
data?
(BTW, I ordered one of Keith's books and George I sprung the $45 bucks for
yours too, so I'm looking forward to fleshing out my understanding of these
things even more).
