Welcome to How We Argue! This is an interactive textbook designed by Harvard philosophers to help you improve your logical reasoning skills.

You can think of How We Argue as a “boot camp for arguments” because you will work through many practice exercises to help you strengthen your “logic muscles.”

We will teach you a method called argument mapping. Research indicates that practice with argument mapping significantly improves the logical reasoning skills that are tested on exams such as the SAT and LSAT.

Each lesson is broken down into very small chunks (short videos and practice exercises) so that you can work through it at your own pace. It will take you about 5-8 hours to work all the way through, if you want to finish everything.
