Highlights
Logic I: Tools for Thinking is used as an introductory or second-year textbook for students in grades 8 or 9 and above (and some 7th graders), in homeschool, co-op, and Christian school settings. Logic I: Tools for Thinking covers a wide range of topics in both formal and informal logic accurately and engagingly. Humorous and serious examples are drawn from a wide range of subject areas: religion, history, politics, literature, science, taxes, and more. If you're looking for in-depth coverage at a sensible pace—with no logic background required—and you want a thoroughly Christian perspective on logic, then Logic I: Tools for Thinking is for you.
"A great introduction to both formal and informal logic. If someone took no other introductory logic course, this would be the one to take . . .
I would use Birkett's Logic again in a heartbeat."
Peter Lipsy, co-op teacher

Scope of Logic I: Tools for Thinking
Logic I begins with vital foundational topics: thinking and reasoning, what logic is, language and how it relates to logic.
The course then moves on to statements and logical operators, along with various tools to use on them. Topics include negation, contradiction, conjunction, disjunction, equivalence, and implication.
On this foundation one of the most useful modern formal (or deductive) logic systems, the sentential calculus, is developed in detail. Formal logic has broad application in such areas as mathematics and computer programming.
The book closes with a substantial section devoted to informal (or inductive) logic. Informal logic encompasses the types of arguments students encounter on a daily basis.
This combination of formal and informal logic topics makes Logic I: Tools for Thinking unusual in its breadth and usefulness. If you're looking for a substantial, year-long course which will strengthen your child's thinking skills (and stimulate yours too!), this course is for you.
"At the end of the course I was astounded by the number of arguments that could be understood and usefully evaluated using the tools in this one textbook."
—Peter Lipsy, co-op teacher

If you will be schooling just one child and do not mind sharing the student book, then just order one teacher's manual and one student book, total. If you will be schooling just one child but want your own student book, then order one teacher's manual and two student books. (Note that the student book is not a workbook; all exercises are done on separate paper. So sharing the student book is possible even if you, too, wish to do all the exercises.)
