And if you knew no facts - If you had no knowledge - What's left
  over? The input from your senses. First thing we learned? Pain
  makes no sense. So we Learn to avoid things that cause pain.
  Second thing we learned? There is a moving thing that does not
  cause us pain. This moving thing takes away pain. We study the
  thing that takes away pain. We call it "mom" - It is through her
  face that we re...cognize all other beings we see. Her face
  forever burns into our minds. We called the feeling we get when
  confusion melts away: love. Love and mom forever stay joined as
  one. Hate is simply love with pain and confusion obstructing its
  passage. In every person we ever meet in our lives, they are,
  deep down, compared to our mothers. Thank you mom. "
