Apophatic theology was one of my early drawing-in points to
  Orthodoxy back-in-the-day. It was the most ... logical (I guess)
  to me that one could best describe the indescribable by using
  "not" instead of "is".

  After all, once you have a term like uncircumscribed... and THEN
  you try to circumscribe... well....

  and yes of course by even using a term like uncircumscribed *is
  circumscribing* by it being a concept... but even in the church
  fathers, they repeatedly (that I remember) remind the reader
  that, they're using the terminology as a lesser form of language
  as it were.... pointers to unknowable knowledge but not the
  knowlege itself, which is experiential in nature etc.
