A Short Response to the “Fine-Tuning Argument” (thanks, Siamang)

I think I was less than clear in my previous post on Francis Collins using creationist rhetoric to argue for the fine-tuning of the universe. That post was not really about the merits of Collins’ argument (which I think are dubious), but about Collins employing tactics that are indistinguishable from those trotted out by the garden-variety creationists against whom Collins still seeks to distinguish himself, including misappropriation of scientific credentials and intentionally misleading language.

With respect to the so-called “fine tuning” argument itself, I’ve noted that the universe is, to 37 significant figures, completely, 100% uninhabitable by humans. It strikes me as a very strange view of the facts when Christians characterize “100% uninhabitable” as “fine tuned for our unique benefit!”

Commenter Siamang makes another terrific point: the fine-tuning argument is vacuous because if the facts were exactly the opposite of what they are, creationists would be able to make the exact same argument! If the constraints of the universe were such that life was incredibly likely, that stars and planets would always form, then the very same Francis Collins-style creationists who declare that the universe is finely-tuned “on a razor’s edge” could make the exact same claims about divine providence in establishing a universe that would always be able to support us. But here, I’ll let Siamang say it, because he’s much pithier than I am:

What I want to know is, if the universe is fine-tuned, Who decided what settings the Tuner had to set the knobs to? I mean, if God was really God, couldn’t He create life in any kind of universe, not just the tuned ones? If God was merely following a recipe, then who wrote the laws that God was following?

I see these as fundamentally flawed competing claims:

[1.] The universe is fine-tuned for life. Therefore YAY GOD!
[2.] The universe is NOT fine-tuned for life, but life exists anyway. Therefore REALLY YAY GOD!

In any universe where life existed, beings using this argument are only extrapolating a God from the fact of their own existence. You don’t need to run this supposition through physics to come to this conclusion. That’s running around the barn to get a tool you’re already holding.

I don’t see a way, in principle, to rescue the “fine-tuning” argument from this criticism.

Video Refutation of the “Fine Tuning” Argument

Most of you have probably seen YouTube user “Thunderf00t‘s” excellent series, “Why People Laugh at Creationists.” (If not, you should.)

Part 10 of that series nicely responds to the Fine Tuning argument as advanced by the Discovery Institute in “The Privileged Planet” (the first clip) and Lee Strobel’s video “The Case For A Creator” (second clip). Here it is:

(After a brief interlude to smack down Kent Hovind — which is a bit too much like kicking a wounded puppy for my tastes — the response continues with part thirteen.)
