The general liar’s revenge sentence shows that logic is inconsistent even if it is incomplete, based on a hypothetical scenario predicated on the assumption of logic gates. Importantly, the assumption of logic gates as hypothesis suffices to show logic to be inconsistent.
That being said, when Gödel talks about incompleteness, he is referring to something tantamount to the incompleteness of logic gates.
Why completeness is preferable:
- Proving the proof – asserting that the proof is true is sufficient to prove the proof. Therefore, logic gates are complete. It doesn’t make sense to prove logic incomplete.
- Logic gates function – a or b?
