the problem atheists have is.......
it requires exactly the same (merely opposite) exercise of faith to say there is no God as it does to say there is a God.
If we accept a Pauline definition of faith it is "the evidence of things not seen,....the substance of that which is not known, ..."
By definition we either know (empirical validation) or we beleive (accept on faith.)
So, those things we know, we can't beleive. That which we believe we don't know. Reduced it follows, what we know we don't beleive, what we beleive we don't know.
Gee, sound like Ed Nelson.
