What is your definition of mysticism? According to Webster, mysticism is either

  1. the experience of mystical union or direct communion with ultimate reality reported by mystics
  2. the belief that direct knowledge of God, spiritual truth, or ultimate reality can be attained through subjective experience (as intuition or insight) 3a : vague speculation : a belief without sound basis b : a theory postulating the possibility of direct and intuitive acquisition of ineffable knowledge or power

My argument has nothing to do with a mystical union or direct communication with ultimate reality, does not even refer to God, spiritual truth or ultimate reality, nor does it concern the acquisition of ineffable knowledge or power. I don't think there is anything vague about my argument, and it is based upon the premise that there are things in the universe of discourse that can appear different at different times. I personally think that premise is reasonable. If you don't, then I would like to hear your argument. Received on Sun Mar 22 2009 - 14:53:51 CET
