Proof sketch for Gödel
WebJan 13, 2015 · Gödel's second incompleteness theorem states that in a system which is free of contradictions, this absence of contradictions is neither provable nor refutable. If we would find a contradiction, then we would have refuted the absence of contradictions. Gödel's theorem states that this is impossible. So we will never encounter a contradiction. WebThe proof of Gödel's incompleteness theorem just sketched is proof-theoretic (also called syntactic) in that it shows that if certain proofs exist (a proof of P(G(P)) or its negation) … WebJan 29, 2024 · 2 Answers Sorted by: 4 Here is such a proof (of the strong version of GIT 1 - that every consistent recursively axiomatizable theory extending PA is incomplete).
