The Power of Logic

Rating:
Summary: an excellent introductory logic textbook
Review: As a college philosophy teacher I have tried many textbooks for teaching informal logic. I am very happy with this book. It presents the material thoroughly and clearly and has tons of useful exercises. I don't need the chapters on symbolic logic for the course I teach, but the material on informal and Aristotelian logic is working very nicely. The publisher maintains an interactive website with additional exercises and review material for students. My students use it and appreciate it.

Review: I found this book highly insightful and would recommend it for any philosophy/logic course in higher education. I did find that the online companion []slightly grating in its' acceptance of certain grammar and punctuation. This aside, I would recommend the book as a whole to anyone interested. It runs the gamut from formal to informal, and adds mighty descriptors of the information along the way. One point deduction for the companion site functionality that this book uses. The book by itself is easy to grasp with enough toughies to keep the average logic student going. I highly recommend it.
