About This Course
Gödel's proof, which states that within any rigidly logical
mathematical system there are propositions (or questions)
that cannot be proved or disproved on the basis of the
axioms within that system and that, therefore, it is
uncertain that the basic axioms of arithmetic will not give
rise to contradictions. This proof has become a hallmark of
20th-century mathematics, and its repercussions continue
to be felt and debated.
