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 someone is skeptical about skepticism, are they still a skeptic?
