Introduction to Logic: Predicate Logic

This clearly written book makes logic interesting and easier to learn without sacrificing content or rigor. It 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. Logic is applied to materials with which readers will be familiar; both examples and exercises are drawn from newspapers, television, and other popular sources. For individuals intrigued by the formal study of logic.

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.
