Provability logic is a modal logic, in which the box operator is interpreted as 'it is provable that'. The point is to capture the notion of a proof predicate of a reasonably rich formal theory. As basic axioms of the provability logic GL (Gödel-Löb), which captures provable in Peano Arithmetic, one takes modal analogues of the Hilbert-Bernays derivability conditions and Löb's theorem (if it is provable that the provability of A implies A, then A is provable). WebGödel's ontological proof is a formal argument by the mathematician Kurt Gödel (1906–1978) for the existence of God.The argument is in a line of development that goes back to Anselm of Canterbury (1033–1109).
