I have defined it. "I don't know".
   I can give you history:
   Raised Methodist (be nice, don't do evil, people of good
   conscience will have a pleasant time. No devil, hell or any of
   that growing up).
   But my grandmother was into Edgar Cayce (an American Mystic) and
   believed a little in ancient aliens, watched Star Trek and
   Doctor Who (and got me into them as well).
   My mother fed us yogurt.
   I didn't follow my grandmother in her Theosophy stuff, and she
   was barely into it anyway, just a little.
   Teenager: Got a job as custodian for my methodist church. I was
   there 7 days a week cleaning up the garbage.
   One day, age of 14, I looked around and said, "This place needs
   more candles".
   Flash forward, experimented with Bahai, Unitarian Universalist,
   Quaker, and then, JUST before almost going Roman Catholic
   (because I had a computer job at a Catholic University and
   enjoyed arguing with the priests-in-training about
   meaning-of-life questions), I opened up the Yellow pages on my
   lunch break and found something called "Eastern Orthodox".
   Never heard of it before then. I was about 24.

   Anyway, ended up getting into it. Stayed in a monastery for a
   very short time and even made it my retirement plan.

   Then, by 30, was bored with it, started a business, and got into
   Science and theoretical physics study hard-core in my spare
   time, after a brief stint with Osho who was fun 'cause he was
   basically, "Don't be an asshole, have fun with your life", which
   reminded me of the stuff I grew up with as a Methodist.

   Now I'm 43 years old. I'm agnostic.

   Does that help?
