A list of software for logic: provers, checkers, etc.

HIS LIST comprises both provers, ie programs which control making proofs by machines, and checkers, ie programs which test the validity of proofs caaried out by humans, provided that a proof is written down in a specially devised language (mentioned below versions of Mizar provide typical examples).

The list is originally found in the American Philosophical Association resources. Encouraged by Authors' statement "additions are welcome", ', we added seven items, viz. programs called "Deductio" (Moscow), "Logika1" (Cracow, Poland), "MacLogic" (St. Andrews, Scottland), "Mizar-MSE"" nd "PC-Mizar" (Warsaw University, Poland), Theax (Japan), and Tableaux II (Oxford). Here follows the original text with the mentioned insertions.

The following is a preliminary list of logic tutorial programmes . This list is compiled from responses to our request for information concerning programmes compatible with Copi's Introductory and Symbolic Logic texts. Additions are welcome.
