I am not an
Atheist, however I do know a great many who would be better
represented (at least in their minds) with a slightly different yet somewhat related answer.
"Reason"
This is the "
credo", so to speak, of the
intellectual Atheist. I am forced to admit that it is what I claim as the capital cause of my
Agnostic lack of belief.
It would also be
noteworthy to point out that "Reason" is also claimed by many modern minded
christians as the very spark of their faith.
Objectively speaking, these are
starkly contrary. Deeper still, down the well of
logic, I find that we may all be better served if we
swapped out "Reason" with "Will" or "Choice" as it is quite a bit more base, honest and more easily
defended. :P
