That was my point. You may believe as you wish, but you cannot demonstrate that this is "God's will," any more than you can prove how many angels can dance on the head of a pin (another traditional preoccupation of Catholic thought).
Angels dancing on pins is an stereotypical criticism of scholaticism. It has never been a "traditional preoccupation of Catholic thought."
I'm not sure what sort of demonstration of God's will you're personally looking for, and I don't really care to debate epistemology with you. The Catholic Church is satisfied discerning God's will through His Scriptures and the traditions of His Church, interpreted for us through the teaching authority of the Magesterium. Obviously, this is not something non-Catholics accept. If that's your point it's a rather obvious one, and not terribly relevant to the discussion on this thread.
Of course not.
If you did, then you wouldve liked to become a Catholic :)
