| 1931 ||[[Kurt Gödel]] showed that sufficiently powerful consistent [[formal system]]s permit the formulation of true theorems that are unprovable by any theorem-proving machine deriving all possible theorems from the axioms. To do this he had to build a universal, integer-based programming language, which is the reason why he is sometimes called the "father of [[theoretical computer science]]".
| [[Ludwig Wittgenstein]]'s ''[[Tractatus Logico-Philosophicus]]'' (1921) inspires [[Rudolf Carnap]] and the [[Logical positivism|logical positivists]] of the [[Vienna Circle]] to use formal logic as the foundation of philosophy. However, Wittgenstein's later work in the 1940s demonstrates that context free symbolic logic is incoherent without human interpretation.
