JS Princeton and HUb',
I love your comments, and I thoroughly agree with the positions you have taken, with one minor exception:
HUb' stated "astrology {IMhO} assumes a nonvaring frame?" I do not believe in astrology, and, as far as I can tell, astrology has nothing to do with the subjects at hand.
I have prepared a more detailed answer. It is currently found at:
