First-order predicate

We first fix a deductive system of first-order predicate calculus, choosing any of the well-known equivalent systems. Gödel's original proof assumed the Hilbert-Ackermann proof system. The completeness theorem says that if a formula is logically valid then there is a finite deduction (a formal proof) of the formula. Thus, the deductive system is "complete" in the sense that no additional inference rules are req…
