Introduction to Logic: Predicate Logic - Softcover

Von der hinteren Coverseite

This clearly written, new edition by Howard Pospesel extends to general statements the system developed in Propositional Logic, revised Third Edition. This new edition covers symbolization, proofs, counterexamples, and truth trees. These topics are presented in graded steps, beginning with the symbolization of categorical propositions and concluding with the properties of relations.

Examples and exercises are drawn from such sources as newspapers, television broadcasts, films, books, and exams. The book enhances students' ability to recognize and evaluate the predicate arguments they encounter outside the logic classroom. Logic is made accessible without sacrificing rigor.

• Many new exercises and examples
• A chapter on truth trees
• New sections treating possible-world counterexamples, intensional contexts, quantifier scope, and quantifier order
• An appendix on metatheory by William G. Lycan

PredLogic, Windows-based software provides an environment in which students symbolize sentences, construct proofs of validity, devise counterexamples, and create truth trees. The program enables students to catch errors as they are made, and it offers hints for solving problems.
