Overview Edit

This Chapter's title is an adaptation of the title of Gödel’s 1931 article, in which his Incompleteness-Theorem was first published. The two major parts of Gödel’s proof are gone through carefully. It is shown how the assumption of consistency of TNT forces one to conclude that TNT (or any similar system) is incomplete. Relations to Euclidean and non-Euclidean geometry are discussed.Implications for the philosophy of mathematics are gone into with some care.
