Introduction to Argument Mapping & Critical Thinking (Ebook/PDF, updated 12/5/2012)

You can download a free short introduction to critical thinking & argument mapping. Go here for more information.

I have made a comprehensive introduction to argument mapping and critical thinking in the form of an ebook. There is evidence that argument mapping is the most effective way to learn critical thinking. Argument maps are visual representations of arguments that help us understand how arguments work, and what it takes to make a good argument.

This ebook is no longer available for free on the website because I am considering publishing it. If you would like to use it for free to teach a class, you can send me a message with information about who you are, the school you work at, and how you plan on using it in the class. I would also require that you give me feedback. You can send me a message using the form below.


This ebook is an introduction to argumentation, argument form, informal fallacies, and more by using illustrative argument maps.

  2. Haven’t read the whole thing yet, but on page 262 there is this statement: “There might be reasons that marijuana should be illegal even if it doesn’t make people happy”, but I believe the word “illegal” should be changed to “legal”.

    This is a great resource – thank you so much for putting this together!

  3. Thank you very much for sharing your knowledge.

    The link “my other free ebooks here.” is broken. However, the “Free Ebooks” link on the right works.

  4. Also, you may want to publish your books on, both to acquire more visibility and to save bandwidth.
