Sorry to tell you this, Birdfeathers, but your nice set-up for a great philosophical discussion is wasted on me. I am a relatively simple person living in rural America. Here '"facts talk, bullshit walks". Even worse, my science background leads reinforces that opinion. Bill D. is philosophy major and a much better BS man than I. Several others may want to take the bait, but as Dave Van Ronk once said, "Somebody else - not me".
