"... nor do I need to to grasp such a concept as I have alluded to above."

hey! we DO agree on something! ;>) And you're not alone.People everywhere are alluding to concepts which they don't grasp!

"...numb between your synapses when you hear a "religious word" being used in a discussion.." , au contraire, mais ami! My synapses experience a heightened level of activity when certain words are used in certain contexts!

"... think metaphorically, for heaven's sake." Ah, now THERE'S the crux! I understand metaphors, and will resort to them at times to evoke a feeling or enhance a concept, but golly gee!, I make a special effort at not mistaking the metaphor for some sort of reality.

If I were to use the " "all concepts (are) everywhere at once" theory.", I would submit that it only makes sense to treat it as the philosophical notion of 'potential'...that is, that any individual concept could be constructed, contemplated and, perhaps, explicated at any time by any person capable of the process. (some, obviously, are not). But this admission is almost trivial....it evokes in me a big "So?" Yes, I can formulate lots of 'concepts' and metaphors, but the phrase " being everywhere at once", if not used very carefully, imparts a dangerous force to 'being', and some folks get images of little 'concepts' floating and swirling about, like dust motes in a light beam.
   It's a bit like asking "How many angels can dance on the head of a pin?" or saying "My karma ran over my dogma." We have formulated correct sentences with vague,imprecise components and still we imagine we are communicating. nicht wahr!
It's a durn can of worms, that's what it is! ...to toss out a metaphor..(or, as my Daddy used to say, "It's a snare and a delusion!")
