Language, Proof and Logic
From Wikipedia, the free encyclopedia
Language, Proof and Logic is an educational software package, devised and written by Jon Barwise and John Etchemendy, geared to teaching formal logic through the use of a tight integration between a textbook (same name as the package) and four software programs, where three of them are logic related (Boole, Fitch and Tarski's World) and the other (Submit) is an internet-based grading service. The name is a pun derived from Language, Truth, and Logic, the philosophy book by A. J. Ayer.
On September 2, 2014, there was launched a massive open online course (MOOC) with the same name, which utilizes this educational software package.
