James Madison Critical Thinking Course
by The Critical Thinking Co. (website )
A comprehensive detective-themed logic course teaching students to analyze arguments and solve problems through formal and informal logic.
Best Fit For
High school students needing a solid foundation in logic for standardized tests (SAT/LSAT), secular homeschoolers, and students who enjoy mystery or detective themes.
Not Recommended For
Students looking for a quick or light elective, or younger middle schoolers who haven't yet developed strong reading comprehension skills.
What Reviewers Say
Reviewers consistently describe the James Madison Critical Thinking Course as one of the most rigorous and comprehensive logic programs available for the middle and high school levels. While many logic programs focus solely on informal fallacies, reviewers like Cathy Duffy highlight that this course dives deep into formal logic, including categorical and propositional logic. The detective-story framework featuring 'Capt. James Madison' is generally praised for making dry material more engaging, though some forum users note that the sheer volume of text can be daunting for students who struggle with reading stamina. A common trade-off mentioned is the density of the material; it is significantly more 'academic' than the publisher's earlier 'Building Thinking Skills' series and may require more parent-student interaction than a standard workbook.
How It Works
The course is contained in a large 530+ page workbook. Each week, the student reads a chapter that advances a detective story involving Captain James Madison, who must solve various cases using logical reasoning. After reading the narrative, the student completes several exercises that require identifying fallacies, evaluating evidence, or constructing logical proofs. A typical session takes 30-45 minutes, twice a week, allowing the course to be completed in one school year.
Switching to This?
There is no formal placement test, but the publisher recommends this for grades 7-12. Families often start this after completing 'Building Thinking Skills Level 3' or as an introductory logic course in 9th or 10th grade. It is suitable for mid-year starts as it is entirely self-contained.

Reviews We Consulted
Highly recommends this rigorous 534-page worktext for high schoolers, noting that the investigative "police detective" theme makes it far more approachable than traditional formal logic.
"This huge, 534-page worktext is more challenging than The Fallacy Detective but it seems more approachable than most other formal logic courses. This is probably because most lessons are presented as cases being investigated by a police detective."
Praises the engaging "mini-mystery" format for keeping students focused on an ambitious curriculum, but cautions that younger students will likely need parental guidance.
"The stories are fun and interesting and help keep students engaged... a student who sticks with the James Madison Critical Thinking Course through the end should be well-grounded in the processes that constitute critical thinking."
Identifies this as the most in-depth logic resource from the publisher, recommending it for older students who have already moved past basic informal logic.
"Our most-used resource is the Building Thinking Skills series, [but] the most in-depth one is the James Madison Critical Thinking Course."
Forum members consider this a solid secular option for high school logic, though some debate whether the workload is sufficient for a full high school credit.
"I plan to have my dd complete the James Madison Critical Thinking Course... By itself it does not seem to be worth a full credit [but it] is good in high school."

How This Compares
Commonly compared to 'The Art of Argument' (Classical Academic Press), which is more visually oriented and focused on fallacies, whereas James Madison covers more formal logic. It is also compared to 'Traditional Logic' (Memoria Press), which takes an Aristotelian approach and is explicitly Christian, while James Madison is secular and modern in its examples.
