Three reasons why you should use the Canon Logic Series
What Everyone is Saying
"The latest editions of both courses have been significantly improved over earlier editions. Most importantly, both courses are easier for a teacher to present to a class group, and they are also easier for students to use working independently."
-Cathy Duffy, Homeschool Curriculum Reviewer
"My daughter took this series for school. My husband and I ended up reading it with her because it was actually enjoyable. Everyone benefits from have 'logical' skills. My emails and conversations are more effective."
"I have BS and masters degrees, but have never had a class in logic. I am loving studying this with my Jr. High daughter. It is written at a level that she can easily understand, yet is very interesting and educational for me, too."

The Fundamentals of Thinking Well

Studying formal logic can be intimidating without the right help, but knowing how to think logically isn’t just for “experts.” It’s the tool for learning how to use other tools. With that in mind, we have painstakingly designed Introductory Logic for everyday students, teachers, and parents who’ve never tackled syllogisms or fallacies before, but who know just how important learning logic is.

You’ll get the benefit of our years of teaching experience — the Canon Logic series has been developed and used at Logos School for over 20 years — as you learn the fundamentals you need to think well wherever you are, including: How to properly define terms for maximum precision and accuracy—and thus win the debate; How to form and interpret statements, the building blocks of logical thought; How to compose valid syllogisms, and—just as importantly—expose the invalid fakes using counterexamples; How to analyze arguments in normal English; How to identify and deflect informal fallacies (one of the most instantly applicable parts of logic); And much more!

Mastering Propositional Arguments

In Intermediate Logic, you’ll get the benefit of our years of teaching experience to help you master propositional arguments: How to interpret and analyze logical operators and truth tables by reviewing and applying the concepts of validity, contradiction, consistency, and equivalence; How to internalize the nine basic rules of inference to derive an argument’s conclusions from its premises; How to easily determine consistency, self-contradiction, tautology, equivalence, and validity by using truth trees; How to apply all these skills to real-life thinkers and writers wherever you encounter them; An all-new optional unit on understanding digital logic, the “language” which modern gadgets (from digital alarm clock displays to computer processors) use to function.

Anybody can learn from Intermediate Logic. The whole series takes advantage of a brand new, clean, easy-to-read layout, lots of margin notes for key points and further study, a step-by-step modern method, and exercises for every lesson (plus review questions and exercises for every unit).

More importantly, anybody can teach Intermediate Logic. Here are the features that make the Teacher Edition for Introductory Logic the obvious choice for educators new to logic, no matter where they teach:
