*Do you think "this sentence is false" is a paradox?* someone
   just asked me.* Here's the answer I gave him: Not necessarily.
   There's other truths. It's true that you typed it. No paradox
   there. It's true that I saw it. No paradox there. It's true that
   it's on the screen right now. Not a paradox. Depends what level
   you're looking at it from. He was satisfied with my answer.* Can
   you see it?
