				Proof Theory
Proof theory, also called metamathematics, is the study of mathematics and mathematical reasoning (Hofstadter 1989) in a general and abstract sense itself. Instead of studying the objects of a particular mathematical theory, it examines the mathematical theories as such, especially with respect to their logical structure. It concentrates mainly on the way in which theorems are derived from axioms.
