what the point in investigating a proposition(the proposition being 'god exists) whose truth value we already cannot determine(and more importantly, that it can be shown that the truth value cannot be attained)? just because there's a difference between existing and not existing that doesn't entail that it's not an empty hypothesis.
Firstly, as I wrote in response to Rationalizer, there may well be different kinds of knowledge with regards to God's existence. It may not be knowable in the empirical sense but that does not preclude other forms of knowledge.
And as for not being able to know whether it is true or not, again, there is the matter of by what means one seeks to know. Is it by empirical inquiry or is it by way of some other method? It may be that the existence of God cannot be decisively known by way of empirical evidence, that does not mean that it cannot be known at all by any method.
And as I said regarding its being an 'empty hypothesis':
Hm, maybe. But the way I look it, an assertion that God exists or doesn't is one with truth value, it's true or false. Therefore, if one states that God exists, regardless of whether it can be known or not, that statement will be either true or false, and therefore, I don't believe that the statement is completely empty.
