Introduction to Logic offers one of the most clear, interesting and accessible introductions to what has long been considered one of the most challenging subjects in philosophy. Harry Gensler engages readers with the basics of logic through practical examples and important arguments in the history of philosophy and from contemporary philosophy. Using simpler and manageable methods for testing arguments, readers are led through in a careful step-by-step way to master the complexities of logic.

Editorial Reviews

From the Publisher
“This new edition is a significant improvement on an already excellent text. The virtues of the original remain, including clear expositions, an intuitive proof procedure that generalizes naturally from propositional logic to more advanced logics, and a wealth of problems drawn from philosophical sources. There are new chapters on the history of logic, deviant logics and the philosophy of logic, and the accompanying LogiCola program has been improved. This is a student-friendly approach to logic.”Michael Bradie, Bowling Green State University

"Professor Gensler's Introduction to Logic is superb! Students are given a first-rate, accessible introduction to the fundamentals of logic through extensive examples from some of the great questions in the history of philosophy. Thus, students are learning philosophy even as they're doing logic. The free program accompanying the text, with its game format, is a genuine tutorial that enables students to master the concepts of each section through new examples and instant feedback. I strongly recommend this fine text for basic and more advanced courses in logic."–Jay Aultman-Moore, Waynesburg University

“This new edition of Introduction to Logic is truly a revision and not just an update. The book has been reorganized in a much more logical sequence. Virtually every chapter in the first edition has been significantly revised for greater clarity…I believe that Gensler’s Introduction to Logic is the best text available today for teaching logic. I look forward to using his book for several years to come.”–Darian C. De Bolt, University of Central Oklahoma
