Dennis Venema asked several questions regarding Intelligent Design. Since there is still much to discuss on the theology of common ancestry, it might be better to start a separate thread. I appreciate Dennis' questions and hope we can work out where we agree and where we don't.
Dennis asks, "I'll need to know what your definition of "design" is, as well as your definition of "scientifically." "
TJ: These are good questions. All of creation is designed and we can't distinguish between what is designed and what isn't. I admit I've seen that distinction in some ID writing but disagree with it. What I mean by design is that certain features may not be explained by the "laws" of science as we know them. This is not merely an argument from ignorance or a God of the gaps explanation, but is based on what we
do know from science. An example is the origin of the first cell. We know the intracellular and extracellular environments are quite different and these chemical and electrical gradients are essential for cell function. Thus the arguments against cellularization are based on knowledge, not ignorance. Same thing with the reduction in entropy that occurs in the formation of macromolecules like DNA, RNA and protein.
DV: As for your "truly random" comment - I'm not sure what you mean, to be honest. I don't think anything is "truly random, even to God" if by that you mean it is beyond God's control.
TJ: I'm glad you feel that way but many of your TE colleagues will argue that evolution is truly random, even to God. God knows the end result but not the means by which we get there. An example is Simon Conway Morris, who holds that the evolutionary process has to end up with some kind of creature that seeks a relationship with God, but the details aren't known, even to God.
DV: As for antipathy towards an "interventionist" idea of God: if evidence were present that such a "discontinuous" event had occurred, I would be happy to weigh it and consider it. It is certainly within God's purview to "intervene" (if one can really call God interacting with His creation 'intervening' in any meaningful way). Nothing in biology that I have seen thus far makes me reach for the "miracle" category as of yet. Nothing I have read in the ID literature makes me reach for that category either.
TJ: Again, I appreciate your answer. Now we can debate the evidence, rather than presuppositions. Many TE's have claimed that it's only an incompetent God who needs to tinker with the evolutionary process because it wasn't designed right in the first place.
DV: To give you some more info on how I view ID, I see it as an argument from analogy: things in biology are analogous to things we know are designed (by people or animals); ergo, the biological entity is designed. Well, the strength of that argument depends on the strength of the analogy - I have yet to see a case where, in my view, the analogy holds up.
TJ: So you agree with the argument from analogy but haven't yet found a convincing example?
DV: The other line of argumentation I see in ID (Dembski's Explanatory Filter, for example) seems to me to be an argument from ignorance. You can't use Dembski's filter unless you have perfect knowledge of all "natural" mechanisms. I have also never seen Dembski actually
use his filter and publish the results. Have you?
TJ: One initial comment about publishing: the names of Behe, Wells, Dembski et al. are anathema to the scientific community. They have tried to publish but their submissions aren't even reviewed. I personally think the Expelled movie was overdone but there's a lot of truth to it. So lack of publications doesn't mean anything. Secondly, I'm not sure what you mean by needing a perfect knowledge of all "natural" mechanisms before you can claim design. Does science ever work that way? We may not invoke new concepts like emergence and self-organization to explain phenomena we can't explain.
DV: Another problem I have with the ID movement is that as it focuses on narrow examples (the flagellum, for example) it seems to dividing biology into "the miraculous bits God did" over against "the natural bits God wasn't involved in because 'Darwinism' can explain those." Well, I prefer to see God as the author and sustainer of the whole deal. In their zeal to "prove" a Designer, I think they're ignoring a big part of His design.
TJ: Agreed, but ID
proper doesn't claim that some things are designed and others aren't. It merely claims that some parts cannot be explained by processes we know and understand. ID also doesn't claim to "prove" a designer. The word "proof" is only appropriate in mathematics and alcohol :-).
I hope this clears up some misconceptions so we can debate the evidence.
