While I used to be an atheist, I find agnosticism more philosophically sound at present.
Doesn't agnosticism state that "truth is unknowable"...or is it "there is no truth"?
Either way, that idea seems self-contradictory...If a person believes there is no truth, how can they believe that the statement "there is no truth" is true?
Or, if the person believes truth is unknowable, then it is not knowable whether the statement "truth is unknowable" is true or not.
Basically, it seems to me that the agnostic is really admitting that the only thing he/she knows is nothing!
