Starling murmurations

From Dr. Timothy Standish:

Why might someone, other than a Darwinist, perceive in starling murmurations a strong suggestion of design? As Jerry Coyne points out, echoing the clip from Flight, in the cold hard world of survival of the fittest, starlings that stick with the group may enhance their odds of surviving predation. But such an effect is an emergent property of the murmuration. Attributing the origin of murmurations to enhanced survival requires first that murmurations exist, thus making for a circular argument. To circumvent this problem, a Darwinist might invoke cooption. Maybe the ancestors of modern starlings gathered together for some other practical purpose and then, in a lucky coincidence, gained the survival advantage provided by murmurations. But think about the resources consumed by daily migrations followed by considerable time flying about with other starlings. It's unclear why any other proposed reason for investing resources this way would not be equally vulnerable to the criticism of circularity.

Flying in formation has advantages that humans quickly recognized once we mastered powered flight. The most obvious of these involves multiple sets of eyes looking out for enemies or obstacles. If human intelligence can figure this out, perhaps clever starlings can as well. But if there is a genetic component to the behavior -- a reasonable assumption given that starlings form murmurations wherever they are in the world while other birds do not -- then a mechanism for creating the required genetic changes would need to anticipate the need fulfilled by murmurations. Darwinian evolution is blind and unguided, incapable by definition of anticipating anything. In the case of human flight, various types of formation flying were developed in anticipation of a need. Generally that was to survive during battles in the air. Formation flying is not something that pilots stumbled upon in the middle of a dogfight then stuck with; it is a solution to an anticipated need. Intelligence alone has been shown to have produced such solutions.

When it comes to design and murmurations, the elephant in the room is the other abilities birds must possess to achieve the phenomenon. They must have the inclination to fly long distances and to congregate. They must have the ability to navigate, the ability to fly, the ability to perceive and react to the other birds they are flying with, and any number of other wonders. Most people, scientists or not, can see this; but Darwinism demands that we turn a blind eye to such things.

One might note, finally, that understanding starling murmurations in terms of design liberates us from a depressing view: that life is nothing more than a struggle for survival. Perhaps starlings share the same joy humans experience in reuniting at the end of the day. Perhaps as they dance this spectacular dance, they enjoy the warmth of one another's company. Dancing, you might imagine, has to be more fun up in the air. When you have observed murmurations on a lovely clear evening, the argument from beauty to intelligent design is only natural. Perhaps in witnessing this, we share some of the joy that starlings themselves feel.

John Loftus vs. Thomas Talbott

Philosopher Thomas Talbott recently criticized John Loftus' "challenge" for theists, dubbed the Outsider Test for Faith. In one of Loftus' many responses to Talbott (he's milking the critique for all it's worth), he makes this silly little claim,

"Talbott, if you want people to respect the philosophical disciplines then please, do it better than you do. You're making the rest of us look bad."

Given most of Loftus' argument against Christianity, this is ridiculous. Consider this coming from the guy who thinks it is a serious challenge to Christianity that God didn't make him with wings so that he could fly and drop poop bombs on people from 1,000 feet in the sky. Oh, no, sorry, that wasn't it; it was so he couldn't fall to his death. Or recall Loftus' claim that he'd rather be a dog in his wife's house than a human in God's world, and that he isn't shows that God isn't good. Apparently, he's unhappy that God hasn't neutered him or made him flexible enough to clean those hard to reach areas. Yes, these are the kinds of arguments Talbott should be giving. The kind atheologians should be giving. These arguments don't make atheologians look bad.

Anywho, enough of picking of Loftus—though he makes it so tempting and easy. Here I'll (again) point out a problem with Loftus outsider test (an issue I've pointed out before and hasn't been rebutted). Loftus writes,

"For Talbott or anyone else to suggest that I might possibility be wrong about an external world then all I can say is "so what?" Probability is the only thing that matters. Until he gives me a reason to think I am probably wrong then I'm not changing anything I think. "

As I've pointed out before, this makes the OTF superfluous. For example, I, like Loftus, will not take the OT for Christianity (or, in his case, for the external world) merely because of the possibility that I might be wrong. Loftus needs to show me that I am probably wrong. But if he can show that Christianity is probably wrong, there's no need, use, or purpose for and to the OTF. It's just a stupid waste of time when Loftus could use that time showing us that Christianity is probably false. But, if Loftus says that the mere fact that my belief in Christianity is at least partly due to where I was raised, and that this shows that Christianity is probably false, then (and besides the fact that it doesn't show this) the same applies, mutantis mutandis, to his belief in an external world EW.

The upshot is: If on the one hand Loftus claims that he doesn't have to take the OTEW until it is shown that his belief in the EW is "probably" false, then the OT is superfluous since once it is shown that some X is probably false, there's no need to take the OTX. On the other hand, if Loftus claims that the "accident of birth" into some culture show that the beliefs of members of that culture are "probably" false and so an OT must be taken (even though it needn't be taken, for supposedly it's already been shown that the beliefs are probably false), then Loftus' belief in an external world is "probably" false and so he needs to take the OTEW. So if Loftus wants us to take his response to Talbott seriously, then he must admit that no Christian should take his OTF until he shows that our belief is "probably" false, or he must admit that his OTF leads to OTEW, OT moral beliefs, OT western logic, OT other minds, OT science, OT etc. And if so, then Loftus is way too busy taking tests to be lecturing us about the tests we need to take. Indeed, him not taking his tests shows me I shouldn't take the ones he wants me to take.

Which horn does Loftus want to be impaled on?
