"WebAs Bernays noted in Hilbert and Bernays 1934, the theorem permits generalizations in two directions: first, the class of theories to which the theorem applies can be broadened to a wider class of theories. Secondly, a more general notion of consistency could be introduced, than what was indicated by Gödel in his 1931 paper. " - Hilbert's basis theorem proof
