U: Universal skepticism: For any assertion P, we don't know if P is true or false.

Proof: The assertion U: "For any assertion P, we don't know if P is true or false" is either true or false. If it's true, we know at least that one assertion is true (U itself) therefore it's false. QED.

If you find a universal skeptic here, let me know.
I'm not anti-Christian. I'm anti-stupid.
