Catholics and ID, part III

For those following the debate between Ed Feser and Jay Richards, Richards has posted his Part III.

The passage I find most critical to the debate:

And he [Feser] reflects on the inadequacy of materialist explanations of DNA and the genetic code, that

seem teleological through and through. Descriptions of this famous molecule make constant reference to the "information," "data," "instructions," "blueprint," "software," "programming," and so on contained within it . . ."

He then speaks of DNA as "directed toward" a sort of "goal" or "end."vii

The ID theorist might sense an ally, but Feser quickly clarifies:


It is important to note that this has nothing whatsoever to do with the "irreducible complexity" that "Intelligent Design" theorists claim certain biological phenomena exhibit; the Aristotelian need not take sides in the debate between Darwinian biologists and "Intelligent Design" theorists (who generally accept the mechanistic view of nature endorsed by their materialist opponents). Final causality is evident in DNA not because of how complex it is, but because of what it does, and would be equally evident however simple in physical structure DNA might have been.viii


I think Feser may have a point. The argument that DNA is specified may be enough to establish teleology. The argument that it is complex may establish how God did it (through secondary causes or immediately).

I'm very taken by the argument of Feser and company on this point, and I actually think ID to a degree does a disservice by trying to get into arguments about complexity. Or at least, by trying to rely on those exclusively.

If you want to establish teleology in nature, it seems to me that the mere fact of DNA's existence does a marvelous job of doing so. Downplaying that and then trying to make a complexity argument do the work strikes me as comparable to someone getting dealt a 21 in blackjack, and then they say "Hit me!"

Hi Crude,

I think the best way to approach the question of origins is to pretend that everyone believes that God created the universe and life, and then all we're trying to do is figure out how. That way we avoid the whole "How to prove God" thing, and just have fun exploring how He did it.
