The Language of First-Order Logic : Including the Macintosh Program Tarski's World 4.0/Book and Disk (Csli Lecture Notes, No 23) (Volume 23)

The Language of First-Order Logic is a complete introduction to first-order symbolic logic, consisting of a computer program and a text. The program, an aid to learning and using symbolic notation, allows one to construct symbolic sentences and possible worlds, and verify that a sentence is well formed. The truth or falsity of a sentence can be determined by playing a deductive game with the computer.
