But his claim is that they are predisposed. Not that they magically understand the concept of God without being introduced to it.
Yes, they're predisposed. They're default wiring in the brain is to take up belief. Before they have the ability to believe, they already have the wiring to believe. And why is that? Read the list and think about what they mean to human nature and the ability for a person to exist as a person in society.
You proved my point. He says that they are "receptive to the idea of God". Where does he claim that they magically understand the concept on their own?
Except that the influence is natural. It's not through indoctrination.
I'm not sure where you get this "magically" from? What do you mean with the reference to the "magically understand"? No, that's not what he's suggesting. The research points to that we've evolved to have these wiring in our brain naturally. We are born with the "God believing brain capacities". And it's actually more effort to un-believe these things than to believe. He has several stories in the book about kids just picking up the "God belief" even after not being influenced in that direction by the parents.
I'm getting really bored of this topic. If you really want to understand what these researchers have said, then pick up their books and read them instead.
Now, I'm really going to try to cut my "lying" and "strawman" contribution to this thread, before I'm called something else ugly.
