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. ==
