"... Now I'll give you something to believe. I'm just one hundred and one,
five months and a day."
"I can't believe that!" said Alice.
"Can't you?" the Queen said in a pitying tone. "Try again: draw a long breath,
and shut your eyes."
Alice laughed. "There's no use trying," she said "one can't believe impossible things."
"I daresay you haven't had much practice," said the Queen. "When
I was your age, I always did it for half-an-hour a day. Why, sometimes I've
believed as many as six impossible things before breakfast..."
I extract from this interaction that the Red Queen is very likely to be religious, because credulity is a requirement for most religions.
This is because believers get rewarded and non-believers punished. A person must have choice of his beliefs if he is to be judged by them.
It seems to me that atheists would tend to feel that we do not have control over what we believe, while theists feel that we do. Do you believe this is probably correct?
