Whither Are You Sure?

- Are you sure?
- I'm not sure.
- Are you sure you're not sure?
- I'm sure I'm not sure.
- Then you're sure.
- I'm sure I'm not sure, but I'm definitely not sure.
- I'm not so sure about that.
- No?
- Certainly.
- So you're sure that you're not sure but you're not sure that I'm not sure.
- I'm not sure - can you repeat that?
- Sure.
- Wait. You're sure you can repeat it but are you sure you're really repeating it correctly?
- Surely you don't think I'd be so unsure in my faculties that I'd forget something I just said.
- I'm sure some people do.
- I'm sure most people don't.
- How can you be so certain?
- Scientific studies on the nature of certainty.
- I heard that those results were uncertain.
- You're thinking of the uncertainty principle.
- Assuredly I am not!
- For someone who thinks he's so unsure you're sure sure of yourself.
- I'm not sure I'm explaining myself well.
- Then why do you sound so sure?
- Are you sure I sound sure? I sure don't hear it.
- Sure you do. It's the certainty in your voice.
- I'm not sure it's certainty.
- What is it then?
- I'm not sure.
- But you're sure you're not sure.
- I'm positive!
