WebJul 14, 2024 · That’s Gödel’s first incompleteness theorem. The second — that no set of axioms can prove its own consistency — easily follows. What would it mean if a set of … Gödel's first incompleteness theorem first appeared as "Theorem VI" in Gödel's 1931 paper "On Formally Undecidable Propositions of Principia Mathematica and Related Systems I". The hypotheses of the theorem were improved shortly thereafter by J. Barkley Rosser (1936) using Rosser's trick. The resulting theorem (incorporating Rosser's improvement) may be paraphrased in English as follows, where "formal system" includes the assumption that the system is effectiv…

WebGödel's first incompleteness theorem states that in a consistent formal system with sufficient arithmetic power, there is a statement P such that no proof either of it or of its negation exists. This does not imply that there is no decision algorithm for the set of theorems of the theory, which would also say that nor P nor not P are theorems. ...
