Well, I've been following this thread for many years. If anyone has ever attempted to document or sustain a "non-materialist" argument, I don't remember it. Nor am I aware that anyone has accepted its merit or validity. Face it, our community of male tech and car geeks is the wrong demography for the non-materialist type of guy. Personally, being very old, I've accumulated some experiences which challenge the materialist notion of consciousness and the strictly material basis of nature. But I don't believe in God. Neither do I believe against God. I do believe that this is not a good forum to find anything other that a one sided debate.
It's probably true that the kind of arguments that are based on belief are met with more criticism here than in other forums and because of that it would be easier to discuss spiritual matters elsewhere as people might be more willing to accept spiritual arguments in a forum for devoted believers. But strictly speaking the arguments wouldn't be any more valid there, just less challenged, or perhaps challenged in other ways.
The problem with religious arguments is that they are usually based on the reasoning:
"If X is true, then X must be true"
And because of this, the argument can only be accepted if you already believe that X is true. It also means that the argument makes perfect sense to those who are religious, and no sense at all to people who aren't and as such it's more or less hopeless to have a discussion on these matters.
From a sociological point of view, religion has (and has had) a great value in that it acts as a common cultural and traditional basis that can keep a group of people united, and in that it provides some basic rules for how people should act towards on another. So there can be great value in believing, or participating in religious activities and rituals, but that value doesn't give it any scientific validity.
If we apply what Famine said in his post, we'd end up with an experiment like the one described in the Guardian article.
Chances are pretty high she would fail this test....
But then how does that explain her getting our grandmother's name in 2 attempts?
Well, let's say that a person has one brother and one sister. Each of their parents also have a brother and a sister each. Each of these aunts /uncles are married and have a son and a daughter.
That gives you a more or less close family of:
Grandmother, grandfather
Mother, father, uncle, uncle, aunt, aunt
Brother, sister, cousin (f), cousin (m), cousin (f), cousin(m), cousin (f), cousin (m), cousin (f), cousin (m).
18 individuals, of which 9 are female and 9 are male.
Assuming that everyone have different names (and ignoring the fact that some names can be for both girls and boys), then for each guess there are nine chances that the guess is correct. With two guesses you've got 18 chances of a correct guess.
So in this case, rather than managing to guess
a specific name in two chances, there are 18 chances to guess
any name.
