Ie, they have the capacity to believe, but would rather not for whatever reason(s). This bias would give rise to loyalty to the idea, and faith in it. Has this possibility been considered?
So the other athiest don't have the 'capacity' to believe? How does one explain the fact that many used to believe then?
This is a rather bizarre concept for why people don't believe.
I don't believe...simply because it's not real. I used to believe, because I didn't know any different. I was told a god was real, like most of the world is told this. And I believed what I was told. I never really questioned it, or knew that could be questioned.
Once I started to honestly question my own belief...it didn't stack up. And when I listen to others that believe...they don't stack up either. People make things up. It's fantasy.
I'm not sure what you mean by 'nonmateriality' specifically. But if science was to uncover evidence of such I would consider it a possiblity. I mean, why not? Black holes don't seem very 'material', but I think that they probably exist. There is enough evidence to suggest it is true. There is nothing to suggest that any one of the millions of gods available to mankind are in any way real or true. And there are just so darn many to choose from, where do you begin?
