Maybe I'm jaded. I don't know what perfection is. Whenever I
   find a perfect answer, I look more closely and I see a lot of
   push and pull, give and take, just on a smaller and smaller
   scale. I'm all for winnowing down the extremes and finding your
   center area... but I don't see hard lines separating certainty
   from uncertainty here... just "here's a firmer spot" and "here's
   a less firm spot". == Balance is a process though, it's not a
   seesaw that doesn't move. ==
