Metalogic

Provides readers with complete proofs of the fundamental metatheorems of standard (that is, basically truth-functional) first order logic. This title includes a complete proof of the undecidability of first order logic, the most important fact about logic to emerge from the work of the last half-century. This work makes available to readers without specialized training in mathematics complete proofs of the fundamental metatheorems of standard (i.e., basically truth-functional) first order logic. Included is a complete proof, accessible to non-mathematicians, of the undecidability of first order logic, the most important fact about logic to emerge from the work of the last half-century. Hunter explains concepts of mathematics and set theory along the way for the benefit of non-mathematicians. He also provides ample exercises with comprehensive answers.
