I didn't have much respect for the guy's command of logic, after reading his claims in a NY Times interview:
http://www.nytimes.com/2007/03/04/magazine/04evolution.t.html?pagewanted=11&ei=5087%0A&em&en=166dbd9e75680e73&ex=1173243600
Views on Evolution of Religious Belief
Barrett is described in the New York Times as a "prominent member of the byproduct camp" and "an observant Christian who believes in “an all-knowing, all-powerful, perfectly good God who brought the universe into being,” [and] “that the purpose for people is to love God and love each other.” He considers that “Christian theology teaches that people were crafted by God to be in a loving relationship with him and other people, Why wouldn’t God, then, design us in such a way as to find belief in divinity quite natural?”
See a problem? He's offering a non-testable hypothesis, asking question of why God designed us a certain way when neither God OR us being "designed" is provable.
But even tentatively accepting his assumptions, his question only leads to ANOTHER question:
Then why didn't God create us so that we HAD to believe in him, just like we HAVE to breathe? Would THAT be more natural? Doesn't the existence of atheists indicate a problem with that hypothesis, indicating yet another design flaw?
And if you're tempted to answer with the old "God made us with free will" argument, that should confirm that he's not offering any kind of scientific testable claim or understanding, but is back in Theologyland, with theology wrapped in the cloak of science. That IS pseudo-science mixed with theology.
He continues:
Having a scientific explanation for mental phenomena does not mean we should stop believing in them. Suppose science produces a convincing account for why I think my wife loves me — should I then stop believing that she does? [3]
So if we have a scientific explanation of the biochemical basis of say, schizophrenia, the schizophrenic should not abandon the hallucinations that he believes are real?
Why would anyone believe in God
In his book Why would anyone believe in God he suggests that "belief in God is an almost inevitable consequence of the kind of minds we have. Most of what we believe comes from mental tools working below our conscious awareness. And what we believe consciously is in large part driven by these unconscious beliefs." and "that beliefs in gods match up well with these automatic assumptions; beliefs in an all-knowing, all-powerful God match up even better." [4]
Poetic stuff, but theological pesudo-science nonsense, nonetheless....
But let's remember how we got here:
CA, your claim was that newborns believe in God (that we weren't born atheists). M-kay, let's give you that point (which I don't agree with; but let's do it tentatively, to make a point).
Your argument would boil down to saying that we should believe in God because BABIES do so?
Should we all suck our thumbs, poop our pants, drool, etc?
You haven't actually just invented a NEW and NOVEL logical fallacy, "appeal to practices of infants"?
