This book/disk package describes a system for learning the principles of analytical reasoning and proof construction, combining graphical and sentential information and presenting a set of logic rules for integrating different forms of information. The accompanying software checks the logical validity of each type of proof. The text is compatible with various natural-deduction-style proof systems. CIP gives the title as Hyperproof for the Macintosh. Annotation copyright Book News, Inc. Portland, Or.

Hyperproof is a system for learning the principles of analytical reasoning and proof construction, consisting of a text and a Macintosh software program. Unlike traditional treatments of first-order logic, Hyperproof combines graphical and sentential information, presenting a set of logical rules for integrating these different forms of information. This strategy allows students to focus on the information content of proofs, rather than the syntactic structure of sentences. Using Hyperproof the student learns to construct proofs of both consequence and nonconsequence using an intuitive proof system that extends the standard set of sentential rules to incorporate information represented graphically. Hyperproof is compatible with various natural-deduction-style proof systems, including the system used in the authors' Language of First-Order Logic.
