[aruanan]

Where does logic come from, if not from our transcendent God?

The inherent, fixed nature of reality?

[anathemized]

I suppose one can assume that, and have faith in that assumption.

"The inherent, fixed nature of reality?"

Who says reality has an "inherent fixed nature"? In fact I've yet to see a workable definition of "reality" which doesn't rely on the some synonym of truth words "truth" or "reality".
