@edgarblythe,
Well said otherwise we couldn't say
anything about what we "know" other than mathematical facts. "I know my car is on the drive" would need to be re-written "I
believe my car is on the drive" in the case of the owner being elseswhere (and even if present his visual recognition could be mistaken). If we actually based our actions on what we were
absolutely certain about, we would be frozen to the spot !
Part of what theists claim they "know" is that their lives and thoughts have significance with respect to their "God", and this knowledge/belief informs their life activities. That knowledge/belief is
functional for them. It becomes
dysfunctional for me ( an atheist) when those activities negatively impinge on my activities. Thus my atheism is
no way logically equivalent to a theistic position, because it is not based on taking one side in a futile discussion of the evidence for metaphysical entities. That is the point which escapes simplistic agnostics.
