    Overall it's an ok book. The teaching is adequate, but I have major issues with some illogical examples in the book that are supposed to be examples of logic. For example (p 52): "Since all Labrador retrievers are four-legged animals, and since all dogs are four-legged animals, it follows that all Labrador retrievers are dogs." This is absolutely not a logical statement even though it's true. It indicates that all four-legged animals are dogs. This is the worst example of logic I have run into in the book so far. They are not all this bad so I have kept using the book.

    I think this text is technically very useful as it covers the basics of formal logic in a comprehensive manner. My major concern is the amount of text (a small font is used) if this book is aimed at the 12 - 15 year old age group, especially if the group is not academically strong. A lot of students will be put of just because of the amount of text they are presented with. I think this textbook is an excellent resource for a teacher or someone wishing to teach themselves. I would not recommend it for use with children in the 12-15 year old age group unless they are great readers and motivated academically.
