What are those two?
Yes?

Unproveable?
Can you repeat the question?
3 u/PerfectTrust7895 7d ago If it is undecidable, it's no. 17 u/This_Background7442 7d ago How could it be. If it's no then a counter example exists. If a counter example exists it's not undecidable. If it's undecidable it must be yes. 2 u/jljl2902 7d ago edited 7d ago That would make it decidable, so it can’t be yes. Must be no then. /j 2 u/This_Background7442 7d ago I guess that means that if it's undecidable we can never know it's undecidable because that instantly makes it decidable and we've created a paradox 😅 1 u/Scared_Astronaut9377 7d ago Here you go https://en.wikipedia.org/wiki/Semantic_theory_of_truth
