The Power Of Logic, Alternate Edition

The Power of Logic renders balanced coverage of informal and formal logic in concise, accurate, and lively prose, making it the most accessible introductory logic text available. The text’s plentiful examples, imaginative exercises, and numerous visual aids help students develop their critical thinking skills as they put the powerful tools of logic to work.In response to teacher feedback on The Power of Logic, Steve Layman now provides an alternate notation for greater pedagogical convenience, along with other small refinements. Foremost among these changes is an alteration in the metalanguage used to state inference rules. The intention is to make this language more student-friendly by using Roman characters to express rules instead of Greek letters.
