Proved incompleteness theorems transforming mathematical logic

Most quoted

"Any consistent formal system F within which a certain amount of elementary arithmetic can be carried out is incomplete; i.e., there are statements of the language of F which can neither be proved nor disproved in F."

— from On Formally Undecidable Propositions of Principia Mathematica and Related Systems, 1931

"Either mathematics is incompletable in this sense, that its evident axioms can never be exhausted by a finite number of formal rules, or else there exist mathematical problems which are undecidable in principle."

— from On Formally Undecidable Propositions of Principia Mathematica and Related Systems I, 1931

"The incompleteness theorems are a profound statement about the limits of formal systems and the indispensable role of human intuition and insight in mathematics."

— from On Formally Undecidable Propositions of Principia Mathematica and Related Systems I, 1931
